partial changelog for 0.2.2.15-alpha
2010-07-21 15:28:34 +02:00
Changes in version 0.2.2.15-alpha - 2010-07-2?
o Major bugfixes:
- Stop assigning the HSDir flag to relays that disable their
DirPort (and thus will refuse to answer directory requests). This
fix should dramatically improve the reachability of hidden services:
hidden services and hidden service clients pick three HSDir relays
to store and retrieve the hidden service descriptor, and currently
about half of the HSDir relays will refuse to work. Bugfix on
0.2.0.10-alpha; fixes part of bug 1693.
o Major features:
- Lower the maximum weighted-fractional-uptime cutoff to 98%. This
should give us approximately 40-50% more Guard-flagged nodes,
improving the anonymity the Tor network can provide and also
decreasing the dropoff in throughput that relays experience when
they first get the Guard flag.
o Minor features:
- Have the controller interface give a more useful message than
"Internal Error" in response to failed GETINFO requests.
o Minor bugfixes:
- Alter directory authorities to always consider Exit-flagged nodes
as potential Guard nodes in their votes. The actual decision to
use Exits as Guards is done in the consensus bandwidth weights.
Fixes bug 1294; bugfix on 0.2.2.10-alpha.
- When the controller is reporting the purpose of circuits that
didn't finish building before the circuit build timeout, it was
printing UNKNOWN_13. Now print EXPIRED. Bugfix on 0.2.2.14-alpha.
- Fix a bug in the controller interface where "GETINFO ns/asdaskljkl"
would return "551 Internal error" rather than "552 Unrecognized key
ns/asdaskljkl".

0.2.2.14-alpha blurb
2010-07-13 21:50:24 +02:00
Tor 0.2.2.14-alpha greatly improves client-side handling of
circuit build timeouts, which are used to estimate speed and improve
performance. We also move to a much better GeoIP database, port Tor to
Windows CE, introduce new compile flags that improve code security,
add an eighth v3 directory authority, and address a lot of more
minor issues.

assert. Bugfix on 0.0.8pre1; fixes bug 1522.
- Ignore negative and large circuit build timeout values that can
happen during a suspend or hibernate. These values caused various
asserts to fire. Bugfix on 0.2.2.2-alpha; fixes bug 1245.
- Alter calculation of Pareto distribution parameter 'Xm' for

Circuit Build Timeout learning to use the weighted average of the
top N=3 modes (because we have three entry guards). Considering
multiple modes should improve the timeout calculation in some cases,
and prevent extremely high timeout values. Bugfix on 0.2.2.2-alpha;
fixes bug 1335.

- Alter calculation of Pareto distribution parameter 'Alpha' to use a

2010-07-12 22:46:28 +02:00
right censored distribution model. This approach improves over the
synthetic timeout generation approach that was producing insanely
high timeout values. Now we calculate build timeouts using truncated
times. Bugfix on 0.2.2.2-alpha; fixes bugs 1245 and 1335.
- Do not close circuits that are under construction when they reach
the circuit build timeout. Instead, leave them building (but do not
use them) for up until the time corresponding to the 95th percentile

on the Pareto CDF or 60 seconds, whichever is greater. This is done
to provide better data for the new Pareto model. This percentile
can be controlled by the consensus.

o Major features:
- Move to the June 2010 Maxmind GeoLite country db (rather than the
June 2009 ip-to-country GeoIP db) for our statistics that count
how many users relays are seeing from each country. Now we have
more accurate data for many African countries.
- Port Tor to build and run correctly on Windows CE systems, using
the wcecompat library. Contributed by Valerio Lupi.
guh. 'git commit' did not do what i expect.
2010-07-12 22:46:28 +02:00
- New "--enable-gcc-hardening" ./configure flag (off by default)
to turn on gcc compile time hardening options. It ensures
that signed ints have defined behavior (-fwrapv), enables
-D_FORTIFY_SOURCE=2 (requiring -O2), adds stack smashing protection
with canaries (-fstack-protector-all), turns on ASLR protection if
supported by the kernel (-fPIE, -pie), and adds additional security
related warnings. Verified to work on Mac OS X and Debian Lenny.
- New "--enable-linker-hardening" ./configure flag (off by default)
to turn on ELF specific hardening features (relro, now). This does
not work with Mac OS X or any other non-ELF binary format.

2010-06-30 00:40:08 +02:00
o New directory authorities:
- Set up maatuska (run by Linus Nordberg) as the eighth v3 directory
authority.
o Minor features:
- New config option "WarnUnsafeSocks 0" disables the warning that
occurs whenever Tor receives only an IP address instead of a
hostname. Setups that do DNS locally over Tor are fine, and we
shouldn't spam the logs in that case.
- Convert the HACKING file to asciidoc, and add a few new sections
to it, explaining how we use Git, how we make changelogs, and
what should go in a patch.

2010-07-09 20:07:54 +02:00
- Add a TIMEOUT_RATE keyword to the BUILDTIMEOUT_SET control port
event, to give information on the current rate of circuit timeouts
over our stored history.
- Add ability to disable circuit build time learning via consensus
parameter and via a LearnCircuitBuildTimeout config option. Also
automatically disable circuit build time calculation if we are
either a AuthoritativeDirectory, or if we fail to write our state
file. Fixes bug 1296.
- More gracefully handle corrupt state files, removing asserts
in favor of saving a backup and resetting state.
guh. 'git commit' did not do what i expect.
2010-07-12 22:46:28 +02:00
- Rename the "log.h" header to "torlog.h" so as to conflict with fewer
system headers.

2010-06-30 00:40:08 +02:00
o Minor bugfixes:
- Build correctly on OSX with zlib 1.2.4 and higher with all warnings
enabled.
- When a2x fails, mention that the user could disable manpages instead
of trying to fix their asciidoc installation.
- Where available, use Libevent 2.0's periodic timers so that our
once-per-second cleanup code gets called even more closely to
once per second than it would otherwise. Fixes bug 943.
- If you run a bridge that listens on multiple IP addresses, and
some user configures a bridge address that uses a different IP
address than your bridge writes in its router descriptor, and the
user doesn't specify an identity key, their Tor would discard the
descriptor because "it isn't one of our configured bridges", and
fail to bootstrap. Now believe the descriptor and bootstrap anyway.
Bugfix on 0.2.0.3-alpha.
- If OpenSSL fails to make a duplicate of a private or public key, log
an error message and try to exit cleanly. May help with debugging
if bug 1209 ever remanifests.
- Save a couple bytes in memory allocation every time we escape
certain characters in a string. Patch from Florian Zumbiehl.
- Make it explicit that we don't cannibalize one-hop circuits. This
happens in the wild, but doesn't turn out to be a problem because
we fortunately don't use those circuits. Many thanks to outofwords
for the initial analysis and to swissknife who confirmed that
two-hop circuits are actually created.

- Make directory mirrors report non-zero dirreq-v[23]-shares again.
Fixes bug 1564; bugfix on 0.2.2.9-alpha.
- Eliminate a case where a circuit build time warning was displayed
after network connectivity resumed. Bugfix on 0.2.2.2-alpha.

Copy the release notes from 0.2.1.26 into the master ChangeLog
2010-06-11 22:31:03 +02:00
Changes in version 0.2.1.26 - 2010-05-02
Tor 0.2.1.26 addresses the recent connection and memory overload
problems we've been seeing on relays, especially relays with their
DirPort open. If your relay has been crashing, or you turned it off
because it used too many resources, give this release a try.
This release also fixes yet another instance of broken OpenSSL libraries
that was causing some relays to drop out of the consensus.
o Major bugfixes:
- Teach relays to defend themselves from connection overload. Relays
now close idle circuits early if it looks like they were intended
for directory fetches. Relays are also more aggressive about closing
TLS connections that have no circuits on them. Such circuits are
unlikely to be re-used, and tens of thousands of them were piling
up at the fast relays, causing the relays to run out of sockets
and memory. Bugfix on 0.2.0.22-rc (where clients started tunneling
their directory fetches over TLS).
- Fix SSL renegotiation behavior on OpenSSL versions like on Centos
that claim to be earlier than 0.9.8m, but which have in reality
backported huge swaths of 0.9.8m or 0.9.8n renegotiation
behavior. Possible fix for some cases of bug 1346.
- Directory mirrors were fetching relay descriptors only from v2
directory authorities, rather than v3 authorities like they should.
Only 2 v2 authorities remain (compared to 7 v3 authorities), leading
to a serious bottleneck. Bugfix on 0.2.0.9-alpha. Fixes bug 1324.
o Minor bugfixes:
- Finally get rid of the deprecated and now harmful notion of "clique
mode", where directory authorities maintain TLS connections to
every other relay.
o Testsuite fixes:
- In the util/threads test, no longer free the test_mutex before all
worker threads have finished. Bugfix on 0.2.1.6-alpha.
- The master thread could starve the worker threads quite badly on
certain systems, causing them to run only partially in the allowed
window. This resulted in test failures. Now the master thread sleeps
occasionally for a few microseconds while the two worker-threads
compete for the mutex. Bugfix on 0.2.0.1-alpha.

prepare the 0.2.2.13-alpha changelog
2010-04-24 02:59:20 +02:00
- Directory authorities now do an immediate reachability check as soon
as they hear about a new relay. This change should slightly reduce
the time between setting up a relay and getting listed as running
in the consensus. It should also improve the time between setting
up a bridge and seeing use by bridge users.
- Directory authorities no longer launch a TLS connection to every
relay as they startup. Now that we have 2k+ descriptors cached,
the resulting network hiccup is becoming a burden. Besides,
authorities already avoid voting about Running for the first half
hour of their uptime.

Changes in version 0.2.2.12-alpha - 2010-04-20
blurbs for two recent alphas
2010-04-24 01:42:34 +02:00
Tor 0.2.2.12-alpha fixes a critical bug in how directory authorities
handle and vote on descriptors. It was causing relays to drop out of
the consensus.
prepare for 0.2.2.12-alpha
2010-04-20 09:53:07 +02:00
o Major bugfixes:
- Many relays have been falling out of the consensus lately because
not enough authorities know about their descriptor for them to get
a majority of votes. When we deprecated the v2 directory protocol,
we got rid of the only way that v3 authorities can hear from each
other about other descriptors. Now authorities examine every v3
vote for new descriptors, and fetch them from that authority. Bugfix
on 0.2.1.23.
- Fix two typos in tor_vasprintf() that broke the compile on Windows,
and a warning in or.h related to bandwidth_weight_rule_t that
prevented clean compile on OS X. Fixes bug 1363; bugfix on
0.2.2.11-alpha.
- Fix a segfault on relays when DirReqStatistics is enabled
and 24 hours pass. Bug found by keb. Fixes bug 1365; bugfix on
0.2.2.11-alpha.

2010-04-20 09:59:23 +02:00
o Minor bugfixes:
- Demote a confusing TLS warning that relay operators might get when
someone tries to talk to their OrPort. It is neither the operator's
fault nor can they do anything about it. Fixes bug 1364; bugfix
on 0.2.0.14-alpha.

- Fix a parsing error that made every possible value of

CircuitPriorityHalflifeMsec, so authorities can tell newer relays
about the option without breaking older ones.

let people test the RefuseUnknownExits idea
2010-03-11 04:43:23 +01:00
o Minor features:
- Experiment with a more aggressive approach to preventing clients
from making one-hop exit streams. Exit relays who want to try it
out can set "RefuseUnknownExits 1" in their torrc, and then look
for "Attempt by %s to open a stream" log messages. Let us know
how it goes!

- Fix a segfault that happens whenever a Tor client that is using
libevent2's bufferevents gets a hup signal. Bugfix on 0.2.2.5-alpha;
fixes bug 1341.
fix the tor-exit-notice.html file (bug 1295)
2010-03-09 02:40:21 +01:00
- When we cleaned up the contrib/tor-exit-notice.html file, we left

- When building the manpage from a tarball, we required asciidoc, but
the asciidoc -> roff/html conversion was already done for the
tarball. Make 'make' complain only when we need asciidoc (either
because we're compiling directly from git, or because we altered
the asciidoc manpage in the tarball). Bugfix on 0.2.2.9-alpha.
- When none of the directory authorities vote on any params, Tor
segfaulted when trying to make the consensus from the votes. We
didn't trigger the bug in practice, because authorities do include

2010-03-09 05:09:49 +01:00
Tor 0.2.2.10-alpha fixes a regression introduced in 0.2.2.9-alpha that
could prevent relays from guessing their IP address correctly. It also
starts the groundwork for another client-side performance boost, since
currently we're not making efficient use of relays that have both the
Guard flag and the Exit flag.

2010-03-07 06:13:12 +01:00
o Major bugfixes:
- Fix a regression from our patch for bug 1244 that caused relays
to guess their IP address incorrectly if they didn't set Address
in their torrc and/or their address fails to resolve. Bugfix on
0.2.2.9-alpha; fixes bug 1269.
Add a changelog entry for the bandwidth weightings.

o Major features (performance):
prepare 0.2.2.10-alpha for release
2010-03-07 06:13:12 +01:00
- Directory authorities now compute consensus weightings that instruct
clients how to weight relays flagged as Guard, Exit, Guard+Exit,
and no flag. Clients that use these weightings will distribute
network load more evenly across these different relay types. The
weightings are in the consensus so we can change them globally in
the future. Extra thanks to "outofwords" for finding some nasty
security bugs in the first implementation of this feature.

o Minor bugfixes (on 0.2.2.x):
Fix another coverity-spotted memleak
2010-02-23 15:02:34 +01:00
- Fix a memleak in the EXTENDCIRCUIT logic. Spotted by coverity.
Bugfix on 0.2.2.9-alpha.
Restrict PerConnBWRate|Burst to INT32_MAX, update manpage All other bandwidthrate settings are restricted to INT32_MAX, but this check was forgotten for PerConnBWRate and PerConnBWBurst. Also update the manpage to reflect the fact that specifying a bandwidth in terabytes does not make sense, because that value will be too large.
2010-02-25 12:25:57 +01:00
- Disallow values larger than INT32_MAX for PerConnBWRate|Burst
config option. Bugfix on 0.2.2.7-alpha.

- Ship the asciidoc-helper file in the tarball, so that people can
build from source if they want to, and touching the .1.txt files
doesn't break the build. Bugfix on 0.2.2.9-alpha.

descriptors. Bugfix on 0.2.1.5-alpha. Discovered by ekir; fixes
bug 1255.
- Fix another dereference-then-NULL-check sequence. Bugfix on
0.2.1.14-rc. Discovered by ekir; fixes bug 1256.
- Make sure we treat potentially not NUL-terminated strings correctly.
Bugfix on 0.1.1.13-alpha. Discovered by rieo; fixes bug 1257.
Update a section of the exit notice file, give it a changelog.
2010-02-23 19:59:34 +01:00
o Code simplifications and refactoring:
- Fix some urls in the exit notice file and make it XHTML1.1 strict

Changes in version 0.2.2.9-alpha - 2010-02-22
blurbs for recent alphas
2010-03-09 05:09:49 +01:00
Tor 0.2.2.9-alpha makes Tor work again on the latest OS X, updates the
location of a directory authority, and cleans up a bunch of small bugs.
prepare for 0.2.2.9-alpha
2010-02-22 06:20:55 +01:00
o Directory authority changes:
- Change IP address for dannenberg (v3 directory authority), and
remove moria2 (obsolete v1, v2 directory authority and v0 hidden
service directory authority) from the list.
Don't assign Exit flag incorrectly exit_policy_is_general_exit() assumed that there are no redundancies in the passed policy, in the sense that we actively combine entries in the policy to really get rid of any redundancy. Since we cannot do that without massively rewriting the policy lines the relay operators set, fix exit_policy_is_general_exit(). Fixes bug 1238, discovered by Martin Kowalczyk.
2010-02-02 14:51:51 +01:00
o Major bugfixes:
prepare for 0.2.2.9-alpha
2010-02-22 06:20:55 +01:00
- Make Tor work again on the latest OS X: when deciding whether to
use strange flags to turn TLS renegotiation on, detect the OpenSSL
version at run-time, not compile time. We need to do this because
Apple doesn't update its dev-tools headers when it updates its
libraries in a security patch.
- Fix a potential buffer overflow in lookup_last_hid_serv_request()
that could happen on 32-bit platforms with 64-bit time_t. Also fix
a memory leak when requesting a hidden service descriptor we've
requested before. Fixes bug 1242, bugfix on 0.2.0.18-alpha. Found
by aakova.

2010-01-29 23:02:17 +01:00
o Minor bugfixes:
Add a changelog entry for fixing bug 1237. We don't have such an entry for 0.2.1.x, since bug 1237 never made it into a released version of 0.2.1.x.
2010-02-02 22:22:12 +01:00
- Fix static compilation by listing the openssl libraries in the right
prepare for 0.2.2.9-alpha
2010-02-22 06:20:55 +01:00
order. Bugfix on Tor 0.2.2.8-alpha; fixes bug 1237.
- Resume handling .exit hostnames in a special way: originally we
stripped the .exit part and used the requested exit relay. In
0.2.2.1-alpha we stopped treating them in any special way, meaning
if you use a .exit address then Tor will pass it on to the exit
relay. Now we reject the .exit stream outright, since that behavior
might be more expected by the user. Found and diagnosed by Scott
Bennett and Downie on or-talk.
- Don't spam the controller with events when we have no file
descriptors available. Bugfix on 0.2.1.5-alpha. (Rate-limiting
for log messages was already solved from bug 748.)
- Avoid a bogus overlapped memcpy in tor_addr_copy(). Reported by
Add changelog for memcpy bug, with credit for "memcpyfail"
2010-02-09 19:08:49 +01:00
"memcpyfail".
Make the DNSPort option work with libevent 2.x We need to use evdns_add_server_port_with_base() when configuring our DNS listener, because libevent segfaults otherwise. Add a macro in compat_libevent.h to pick the correct implementation depending on the libevent version. Fixes bug 1143, found by SwissTorExit
2010-02-19 17:19:33 +01:00

prepare for 0.2.2.9-alpha
2010-02-22 06:20:55 +01:00
- Emit a GUARD DROPPED controller event for a case we missed.
- Make more fields in the controller protocol case-insensitive, since
control-spec.txt said they were.
- Refactor resolve_my_address() to not use gethostbyname() anymore.
Fixes bug 1244; bugfix on 0.0.2pre25. Reported by Mike Mestnik.
network-status-version must come first in a vote/consensus Spec conformance issue: The code didn't force the network-status-version token to be the first token in a v3 vote or consensus. Problem discovered by Parakeep.

Fix ChangeLog entry for asciidoc branch.
2010-01-27 19:27:53 +01:00
o Code simplifications and refactoring:
prepare for 0.2.2.9-alpha
2010-02-22 06:20:55 +01:00
- Generate our manpage and HTML documentation using Asciidoc. This
change should make it easier to maintain the documentation, and
produce nicer HTML.
- Remove the --enable-iphone option. According to reports from Marco
Bonetti, Tor builds fine without any special tweaking on recent
iPhone SDK versions.

Expand homedirs in paths passed to tor-checkkey This is so that coverity stops complaining about using a user-supplied string with the open() syscall. Let's see if it works.
2010-02-22 12:08:58 +01:00

Changes in version 0.2.1.25 - 2010-03-16
Tor 0.2.1.25 fixes a regression introduced in 0.2.1.23 that could
prevent relays from guessing their IP address correctly. It also fixes
several minor potential security bugs.
Zero a cipher completely before freeing it We used to only zero the first ptrsize bytes of the cipher. Since cipher is large enough, we didn't zero too many bytes. Discovered and fixed by ekir. Fixes bug 1254.
2010-02-22 11:39:29 +01:00
o Major bugfixes:
clean up the 0.2.1.25 changelog
2010-03-07 04:39:34 +01:00
- Fix a regression from our patch for bug 1244 that caused relays
to guess their IP address incorrectly if they didn't set Address
in their torrc and/or their address fails to resolve. Bugfix on
0.2.1.23; fixes bug 1269.
- When freeing a session key, zero it out completely. We only zeroed
the first ptrsize bytes. Bugfix on 0.0.2pre8. Discovered and
patched by ekir. Fixes bug 1254.
Apply Roger's bug 1269 fix. From http://archives.seul.org/tor/relays/Mar-2010/msg00006.html : As I understand it, the bug should show up on relays that don't set Address to an IP address (so they need to resolve their Address line or their hostname to guess their IP address), and their hostname or Address line fails to resolve -- at that point they'll pick a random 4 bytes out of memory and call that their address. At the same time, relays that *do* successfully resolve their address will ignore the result, and only come up with a useful address if their interface address happens to be a public IP address.

Proper NULL checking for hsdesc publication Fix a dereference-then-NULL-check sequence. This bug wasn't triggered in the wild, but we should fix it anyways in case it ever happens.

Changes in version 0.2.1.24 - 2010-02-21
Tor 0.2.1.24 makes Tor work again on the latest OS X -- this time
for sure!
Fix a memory corruption bug while collecting bridge stats We accidentally freed the internal buffer for bridge stats when we were writing the bridge stats file or honoring a control port request for said data. Change the interfaces for geoip_get_bridge_stats* to prevent these problems, and remove the offending free/add a tor_strdup. Fixes bug 1208.

again on the latest OS X, and updates the location of a directory
authority.
weight guard choice by bandwidth; discard old guards
2010-01-19 23:30:52 +01:00
o Major bugfixes (performance):
- We were selecting our guards uniformly at random, and then weighting
which of our guards we'd use uniformly at random. This imbalance
meant that Tor clients were severely limited on throughput (and
probably latency too) by the first hop in their circuit. Now we
select guards weighted by currently advertised bandwidth. We also
automatically discard guards picked using the old algorithm. Fixes
bug 1217; bugfix on 0.2.1.3-alpha. Found by Mike Perry.

throughout the month, but we still avoid leaving a precise timestamp
in the state file about when we first picked the guard. Improves
over the behavior introduced in 0.1.2.17.

- When choosing which cells to relay first, relays can now favor
circuits that have been quiet recently, to provide lower latency
for low-volume circuits. By default, relays enable or disable this
feature based on a setting in the consensus. You can override
this default by using the new "CircuitPriorityHalflife" config
option. Design and code by Ian Goldberg, Can Tang, and Chris
Alexander.

2009-12-21 10:38:49 +01:00
- If EntryNodes, ExitNodes, ExcludeNodes, or ExcludeExitNodes
change during a config reload, mark and discard all our origin
circuits. This fix should address edge cases where we change the
config options and but then choose a circuit that we created before
the change.
- If EntryNodes or ExitNodes are set, be more willing to use an
unsuitable (e.g. slow or unstable) circuit. The user asked for it,
they get it.
- Make EntryNodes config option much more aggressive even when
StrictNodes is not set. Before it would prepend your requested
entrynodes to your list of guard nodes, but feel free to use others
after that. Now it chooses only from your EntryNodes if any of
those are available, and only falls back to others if a) they're
all down and b) StrictNodes is not set.
- Now we refresh your entry guards from EntryNodes at each consensus
fetch -- rather than just at startup and then they slowly rot as
the network changes.

o Major bugfixes:
- Stop bridge directory authorities from answering dbg-stability.txt
directory queries, which would let people fetch a list of all
bridge identities they track. Bugfix on 0.2.1.6-alpha.
New config option "CircuitStreamTimeout" New config option "CircuitStreamTimeout" to override our internal timeout schedule for how many seconds until we detach a stream from a circuit and try a new circuit. If your network is particularly slow, you might want to set this to a number like 60.

for security-conscious users to recognize when a local application
is knocking on their controller door. Suggested by bug 1196.

- Avoid a mad rush at the beginning of each month when each client
rotates half of its guards. Instead we spread the rotation out
throughout the month, but we still avoid leaving a precise timestamp
in the state file about when we first picked the guard. Improves
over the behavior introduced in 0.1.2.17.

- Fix statistics on client numbers by country as seen by bridges that
were broken in 0.2.2.1-alpha. Also switch to reporting full 24-hour
intervals instead of variable 12-to-48-hour intervals.
- After we free an internal connection structure, overwrite it
with a different memory value than we use for overwriting a freed

o Removed features:

service authorities could have used to track statistics of overall
hidden service usage.
Fix compilation on OSX 10.3. On this OSX version, there is a stub mlockall() function that doesn't work, *and* the declaration for it is hidden by an '#ifdef _P1003_1B_VISIBLE'. This would make autoconf successfully find the function, but our code fail to build when no declaration was found. This patch adds an additional test for the declaration.

Tor 0.2.1.22 fixes a critical privacy problem in bridge directory
authorities -- it would tell you its whole history of bridge descriptors
if you make the right directory request. This stable update also
rotates two of the seven v3 directory authority keys and locations.

Changes in version 0.2.1.21 - 2009-12-21
Tor 0.2.1.21 fixes an incompatibility with the most recent OpenSSL
library. If you use Tor on Linux / Unix and you're getting SSL
renegotiation errors, upgrading should help. We also recommend an
upgrade if you're an exit relay.
o Major bugfixes:
- Work around a security feature in OpenSSL 0.9.8l that prevents our
handshake from working unless we explicitly tell OpenSSL that we
are using SSL renegotiation safely. We are, of course, but OpenSSL
0.9.8l won't work unless we say we are.
- Avoid crashing if the client is trying to upload many bytes and the
circuit gets torn down at the same time, or if the flip side
happens on the exit relay. Bugfix on 0.2.0.1-alpha; fixes bug 1150.
o Minor bugfixes:
- Do not refuse to learn about authority certs and v2 networkstatus
documents that are older than the latest consensus. This bug might
have degraded client bootstrapping. Bugfix on 0.2.0.10-alpha.
Spotted and fixed by xmux.
- Fix a couple of very-hard-to-trigger memory leaks, and one hard-to-
trigger platform-specific option misparsing case found by Coverity
Scan.
- Fix a compilation warning on Fedora 12 by removing an impossible-to-
trigger assert. Fixes bug 1173.

2010-01-19 21:20:07 +01:00
Tor 0.2.2.6-alpha lays the groundwork for many upcoming features:
support for the new lower-footprint "microdescriptor" directory design,
future-proofing our consensus format against new hash functions or
other changes, and an Android port. It also makes Tor compatible with
the upcoming OpenSSL 0.9.8l release, and fixes a variety of bugs.

Partially implements Proposal 162: "Publish the consensus in
multiple flavors".
- Directory authorities can now agree on and publish small summaries
of router information that clients can use in place of regular
server descriptors. This transition will eventually allow clients
to use far less bandwidth for downloading information about the
network. Begins the implementation of Proposal 158: "Clients
download consensus + microdescriptors".
Changelog for microdescriptor branch.
2009-10-19 06:39:20 +02:00
- The directory voting system is now extensible to use multiple hash

algorithms for signatures and resource selection. Newer formats
are signed with SHA256, with a possibility for moving to a better
hash algorithm in the future.
Implement DisableAllSwap to avoid putting secret info in page files. This commit implements a new config option: 'DisableAllSwap' This option probably only works properly when Tor is started as root. We added two new functions: tor_mlockall() and tor_set_max_memlock(). tor_mlockall() attempts to mlock() all current and all future memory pages. For tor_mlockall() to work properly we set the process rlimits for memory to RLIM_INFINITY (and beyond) inside of tor_set_max_memlock(). We behave differently from mlockall() by only allowing tor_mlockall() to be called one single time. All other calls will result in a return code of 1. It is not possible to change DisableAllSwap while running. A sample configuration item was added to the torrc.complete.in config file. A new item in the man page for DisableAllSwap was added. Thanks to Moxie Marlinspike and Chris Palmer for their feedback on this patch. Please note that we make no guarantees about the quality of your OS and its mlock/mlockall implementation. It is possible that this will do nothing at all. It is also possible that you can ulimit the mlock properties of a given user such that root is not required. This has not been extensively tested and is unsupported. I have included some comments for possible ways we can handle this on win32.
2009-10-22 06:21:57 +02:00
- New DisableAllSwap option. If set to 1, Tor will attempt to lock all
clean up changelog for the 0.2.2.6-alpha release
2009-11-17 13:02:17 +01:00
current and future memory pages via mlockall(). On supported
platforms (modern Linux and probably BSD but not Windows or OS X),
this should effectively disable any and all attempts to page out
memory. This option requires that you start your Tor as root --
if you use DisableAllSwap, please consider using the User option
to properly reduce the privileges of your Tor.
- Numerous changes, bugfixes, and workarounds from Nathan Freitas
to help Tor build correctly for Android phones.

Fix a crash when using evdns from Libevent 2. When we tried to use the deprecated non-threadsafe evdns interfaces in Libevent 2 without using the also-deprecated event_init() interface, Libevent 2 would sensibly crash, since it has no guess where to find the Libevent library.

Changes in version 0.2.1.20 - 2009-10-15
Tor 0.2.1.20 fixes a crash bug when you're accessing many hidden
services at once, prepares for more performance improvements, and
fixes a bunch of smaller bugs.
The Windows and OS X bundles also include a more recent Vidalia,
and switch from Privoxy to Polipo.
The OS X installers are now drag and drop. It's best to un-install
Tor/Vidalia and then install this new bundle, rather than upgrade. If
you want to upgrade, you'll need to update the paths for Tor and Polipo
in the Vidalia Settings window.
o Major bugfixes:
- Send circuit or stream sendme cells when our window has decreased
by 100 cells, not when it has decreased by 101 cells. Bug uncovered
by Karsten when testing the "reduce circuit window" performance
patch. Bugfix on the 54th commit on Tor -- from July 2002,
before the release of Tor 0.0.0. This is the new winner of the
oldest-bug prize.
- Fix a remotely triggerable memory leak when a consensus document
contains more than one signature from the same voter. Bugfix on
0.2.0.3-alpha.
- Avoid segfault in rare cases when finishing an introduction circuit
as a client and finding out that we don't have an introduction key
for it. Fixes bug 1073. Reported by Aaron Swartz.
o Major features:
- Tor now reads the "circwindow" parameter out of the consensus,
and uses that value for its circuit package window rather than the
default of 1000 cells. Begins the implementation of proposal 168.
o New directory authorities:
- Set up urras (run by Jacob Appelbaum) as the seventh v3 directory
authority.
- Move moria1 and tonga to alternate IP addresses.
o Minor bugfixes:
- Fix a signed/unsigned compile warning in 0.2.1.19.
- Fix possible segmentation fault on directory authorities. Bugfix on
0.2.1.14-rc.
- Fix an extremely rare infinite recursion bug that could occur if
we tried to log a message after shutting down the log subsystem.
Found by Matt Edman. Bugfix on 0.2.0.16-alpha.
- Fix an obscure bug where hidden services on 64-bit big-endian
systems might mis-read the timestamp in v3 introduce cells, and
refuse to connect back to the client. Discovered by "rotor".
Bugfix on 0.2.1.6-alpha.
- We were triggering a CLOCK_SKEW controller status event whenever
we connect via the v2 connection protocol to any relay that has
a wrong clock. Instead, we should only inform the controller when
it's a trusted authority that claims our clock is wrong. Bugfix
on 0.2.0.20-rc; starts to fix bug 1074. Reported by SwissTorExit.
- We were telling the controller about CHECKING_REACHABILITY and
REACHABILITY_FAILED status events whenever we launch a testing
circuit or notice that one has failed. Instead, only tell the
controller when we want to inform the user of overall success or
overall failure. Bugfix on 0.1.2.6-alpha. Fixes bug 1075. Reported
by SwissTorExit.
- Don't warn when we're using a circuit that ends with a node
excluded in ExcludeExitNodes, but the circuit is not used to access
the outside world. This should help fix bug 1090. Bugfix on
0.2.1.6-alpha.
- Work around a small memory leak in some versions of OpenSSL that
stopped the memory used by the hostname TLS extension from being
freed.
o Minor features:
- Add a "getinfo status/accepted-server-descriptor" controller
command, which is the recommended way for controllers to learn
whether our server descriptor has been successfully received by at
least on directory authority. Un-recommend good-server-descriptor
getinfo and status events until we have a better design for them.

addresses around to reduce the impact from recent blocking events,
and fixes a few smaller bugs.

Debugging logs for TLS handshake The big change is to add a function to display the current SSL handshake state, and to log it everywhere reasonable. (A failure in SSL23_ST_CR_SRVR_HELLO_A is different from one in SSL3_ST_CR_SESSION_TICKET_A.) This patch also adds a new log domain for OR handshaking, so you can pull out all the handshake log messages without having to run at debug for everything. For example, you'd just say "log notice-err [handshake]debug-err file tor.log".

Debugging logs for TLS handshake The big change is to add a function to display the current SSL handshake state, and to log it everywhere reasonable. (A failure in SSL23_ST_CR_SRVR_HELLO_A is different from one in SSL3_ST_CR_SESSION_TICKET_A.) This patch also adds a new log domain for OR handshaking, so you can pull out all the handshake log messages without having to run at debug for everything. For example, you'd just say "log notice-err [handshake]debug-err file tor.log".

Fix a couple of smaller issues with gathering statistics. - Avoid memmoving 0 bytes which might lead to compiler warnings. - Don't require relays to be entry node AND bridge at the same to time to record clients. - Fix a memory leak when writing dirreq-stats. - Don't say in the stats files that measurement intervals are twice as long as they really are. - Reduce minimum observation time for requests to 12 hours, or we might never record usage. - Clear exit stats correctly after writing them, or we accumulate old stats over time. - Reset interval start for buffer stats, too.

2009-10-10 19:33:17 +02:00
Tor 0.2.2.2-alpha introduces our latest performance improvement for
clients: Tor tracks the average time it takes to build a circuit, and
avoids using circuits that take too long to build. For fast connections,
this feature can cut your expected latency in half. For slow or flaky
connections, it could ruin your Tor experience. Let us know if it does!
Implement proposal 167: Authorities vote on network parameters. This code adds a new field to vote on: "params". It consists of a list of sorted key=int pairs. The output is computed as the median of all the integers for any key on which anybody voted. Improved with input from Roger.
2009-09-15 04:15:57 +02:00
o Major features:
give proposal 151 a changelog and other touchups
2009-09-17 07:42:33 +02:00
- Tor now tracks how long it takes to build client-side circuits
over time, and adapts its timeout to local network performance.
Since a circuit that takes a long time to build will also provide
bad performance, we get significant latency improvements by
discarding the slowest 20% of circuits. Specifically, Tor creates
circuits more aggressively than usual until it has enough data
points for a good timeout estimate. Implements proposal 151.
We are especially looking for reports (good and bad) from users with
both EDGE and broadband connections that can move from broadband
to EDGE and find out if the build-time data in the .tor/state gets
reset without loss of Tor usability. You should also see a notice
log message telling you that Tor has reset its timeout.

- Directories that set "DirReqStatistics 1" write statistics on
directory request to disk every 24 hours. As compared to the
--enable-geoip-stats flag in 0.2.1.x, there are a few improvements:
1) stats are written to disk exactly every 24 hours; 2) estimated
shares of v2 and v3 requests are determined as mean values, not at
the end of a measurement period; 3) unresolved requests are listed
with country code '??'; 4) directories also measure download times.

Merge commit 'ioerror/DirFetchInfoExtraEarly' Conflicts: ChangeLog
2009-07-25 06:52:54 +02:00
- Certain Tor clients (such as those behind check.torproject.org) may
want to fetch the consensus in an extra early manner. To enable this
a user may now set FetchDirInfoExtraEarly to 1. This also depends on
setting FetchDirInfoEarly to 1. Previous behavior will stay the same
as only certain clients who must have this information sooner should
set this option.
Add the first 8 bytes of the git commit digest to our versions. Note that unlike subversion revision numbers, it isn't meaningful to compare these for anything but equality. We define a sort-order anyway, in case one of these accidentally slips into a recommended-versions list.
2009-06-12 19:38:37 +02:00
- Instead of adding the svn revision to the Tor version string, report

Command-line option to dump SHA1 digests of all source files. Now, when you call tor --digests, it dumps the SHA1 digest of each source file that Tor was built with. We support both 'sha1sum' and 'openssl sha1'. If the user is building from a tarball and they haven't edited anything, they don't need any program that calculates SHA1. If they _have_ modified a file but they don't have a program to calculate SHA1, we try to build so we do not output digests.

services on Tor 0.2.1.3-alpha through 0.2.1.18.
three hacks to workaround bug 1038 The problem is that clients and hidden services are receiving relay_early cells, and they tear down the circuit. Hack #1 is for rendezvous points to rewrite relay_early cells to relay cells. That way there are never any incoming relay_early cells. Hack #2 is for clients and hidden services to never send a relay_early cell on an established rendezvous circuit. That works around rendezvous points that haven't upgraded yet. Hack #3 is for clients and hidden services to not tear down the circuit when they receive an inbound relay_early cell. We already refuse extend cells at clients.

Write fingerprint to file and log without spaces Now it will look like the fingerprints in our bridges documentation, and confuse fewer users.
2009-07-28 04:51:20 +02:00
o Minor features:
- When a relay/bridge is writing out its identity key fingerprint to
the "fingerprint" file and to its logs, write it without spaces. Now
it will look like the fingerprints in our bridges documentation,
and confuse fewer users.

Tor 0.2.1.18 lays the foundations for performance improvements,
adds status events to help users diagnose bootstrap problems, adds
optional authentication/authorization for hidden services, fixes a
variety of potential anonymity problems, and includes a huge pile of
other features and bug fixes.

Changes in version 0.2.1.17-rc - 2009-07-07
add blurbs for recent release candidates
2009-07-24 22:53:40 +02:00
Tor 0.2.1.17-rc marks the fourth -- and hopefully last -- release
candidate for the 0.2.1.x series. It lays the groundwork for further
client performance improvements, and also fixes a big bug with directory
authorities that were causing them to assign Guard and Stable flags
poorly.
The Windows bundles also finally include the geoip database that we
thought we'd been shipping since 0.2.0.x (oops), and the OS X bundles
should actually install Torbutton rather than giving you a cryptic
failure message (oops).
Revise 0.2.1.17-rc changelog.
2009-07-02 16:13:01 +02:00
o Major features:
- Clients now use the bandwidth values in the consensus, rather than
the bandwidth values in each relay descriptor. This approach opens
the door to more accurate bandwidth estimates once the directory
authorities start doing active measurements. Implements more of
proposal 141.

o Major bugfixes:
Revise 0.2.1.17-rc changelog.
2009-07-02 16:13:01 +02:00
- When Tor clients restart after 1-5 days, they discard all their
cached descriptors as too old, but they still use the cached
consensus document. This approach is good for robustness, but
bad for performance: since they don't know any bandwidths, they
end up choosing at random rather than weighting their choice by
speed. Fixed by the above feature of putting bandwidths in the
consensus. Bugfix on 0.2.0.x.
and give the bug 969 fixes a changelog
2009-06-20 12:14:32 +02:00
- Directory authorities were neglecting to mark relays down in their
internal histories if the relays fall off the routerlist without
ever being found unreachable. So there were relays in the histories
that haven't been seen for eight months, and are listed as being
up for eight months. This wreaked havoc on the "median wfu"
and "median mtbf" calculations, in turn making Guard and Stable
flags very wrong, hurting network performance. Fixes bugs 696 and
969. Bugfix on 0.2.0.6-alpha.
Serve DirPortFrontPage even if the write bucket is low. arma's rationale: "I think this is a bug, since people intentionally set DirPortFrontPage, so they really do want their relay to serve that page when it's asked for. Having it appear only sometimes (or roughly never in Sebastian's case) makes it way less useful." Fixes bug 1013; bugfix on 0.2.1.8-alpha.
2009-06-22 18:34:32 +02:00

our quotas recently. Fixes bug 1013; bugfix on 0.2.1.8-alpha.
- The control port would close the connection before flushing long
replies, such as the network consensus, if a QUIT command was issued
before the reply had completed. Now, the control port flushes all
pending replies before closing the connection. Also fixed a spurious
warning when a QUIT command is issued after a malformed or rejected
AUTHENTICATE command, but before the connection was closed. Patch
by Marcus Griep. Bugfix on 0.2.0.x; fixes bugs 1015 and 1016.
Make an attempt to fix bug 1024. The internal error "could not find intro key" occurs when we want to send an INTRODUCE1 cell over a recently finished introduction circuit and think we built the introduction circuit with a v2 hidden service descriptor, but cannot find the introduction key in our descriptor. My first guess how we can end up in this situation is that we are wrong in thinking that we built the introduction circuit based on a v2 hidden service descriptor. This patch checks if we have a v0 descriptor, too, and uses that instead.
2009-06-30 20:35:03 +02:00
- When we can't find an intro key for a v2 hidden service descriptor,
fall back to the v0 hidden service descriptor and log a bug message.

2009-08-26 20:11:53 +02:00
Changes in version 0.2.0.35 - 2009-06-24
o Security fix:
- Avoid crashing in the presence of certain malformed descriptors.
Found by lark, and by automated fuzzing.
- Fix an edge case where a malicious exit relay could convince a
controller that the client's DNS question resolves to an internal IP
address. Bug found and fixed by "optimist"; bugfix on 0.1.2.8-beta.
o Major bugfixes:
- Finally fix the bug where dynamic-IP relays disappear when their
IP address changes: directory mirrors were mistakenly telling
them their old address if they asked via begin_dir, so they
never got an accurate answer about their new address, so they
just vanished after a day. For belt-and-suspenders, relays that
don't set Address in their config now avoid using begin_dir for
all direct connections. Should fix bugs 827, 883, and 900.
- Fix a timing-dependent, allocator-dependent, DNS-related crash bug
that would occur on some exit nodes when DNS failures and timeouts
occurred in certain patterns. Fix for bug 957.
o Minor bugfixes:
- When starting with a cache over a few days old, do not leak
memory for the obsolete router descriptors in it. Bugfix on
0.2.0.33; fixes bug 672.
- Hidden service clients didn't use a cached service descriptor that
was older than 15 minutes, but wouldn't fetch a new one either,
because there was already one in the cache. Now, fetch a v2
descriptor unless the same descriptor was added to the cache within
the last 15 minutes. Fixes bug 997; reported by Marcus Griep.

Fix gprof bottlenecks on exit nodes found by Jacob. Apparently all the stuff that does a linear scan over all the DNS cache entries can get really expensive when your DNS cache is very large. It's hard to say how much this will help performance, since gprof doesn't count time spent in OpenSSL or zlib, but I'd guess 10%. Also, this patch removes calls to assert_connection_ok() from inside the read and write callbacks, which are similarly unneeded, and a little costlier than I'm happy with. This is probably worth backporting to 0.2.0.
2009-06-03 19:52:03 +02:00

o Minor features:
- Update to the "June 3 2009" ip-to-country file.
tor-resolve: Don't automatically refuse .onion addresses. If the Tor is running with AutomapHostsOnResolve set, it _is_ reasonable to do a DNS lookup on a .onion address. So instead we make tor-resolve willing to try to resolve anything. Only if Tor refuses to resolve it do we suggest to the user that resolving a .onion address may not work. Fix for bug 1005.
2009-06-18 17:08:10 +02:00
- Do not have tor-resolve automatically refuse all .onion addresses;

- Actually return -1 in the error case for read_bandwidth_usage().
Harmless bug, since we currently don't care about the return value
anywhere. Bugfix on 0.2.0.9-alpha.
Better debugging output for bug 977 case. (Don't crash immediately if we have leftover chunks to free after freeing chunks in a buffer freelist; instead log a debugging message that might help.)
2009-05-12 19:54:21 +02:00

- Fix an assertion failure on 64-bit platforms when we allocated
memory right up to the end of a memarea, then realigned the memory
one step beyond the end. Fixes a possible cause of bug 930.
Use a mutex to protect the count of open sockets. This matters because a cpuworker can close its socket when it finishes. Cpuworker typically runs in another thread, so without a lock here, we can have a race condition and get confused about how many sockets are open. Possible fix for bug 939.

Fix an assertion-failure in memarea_alloc() on 64-bit platforms. The trick is that we should assert that our next_mem pointer has not run off the end of the array _before_ we realign the pointer, since doing that could take us over the end... but only if we're on a system where malloc() gives us ram in increments smaller than sizeof(void*).

Raise the minimum bandwidth to be a relay from 20000 bytes to 20480 bytes (aka 20KB/s), to match our documentation. Also update directory authorities so they always assign the Fast flag to relays with 20KB/s of capacity.

Tor 0.2.1.14-rc marks the first release candidate for the 0.2.1.x
series. It begins fixing some major performance problems, and also
finally addresses the bug that was causing relays on dynamic IP
addresses to fall out of the directory.
Clients replace entry guards that were chosen more than a few months ago. This change should significantly improve client performance, especially once more people upgrade, since relays that have been a guard for a long time are currently overloaded. svn:r19287

IP address changes: directory mirrors were mistakenly telling
them their old address if they asked via begin_dir, so they
never got an accurate answer about their new address, so they
just vanished after a day. For belt-and-suspenders, relays that
don't set Address in their config now avoid using begin_dir for
all direct connections. Should fix bugs 827, 883, and 900.

2009-03-13 05:47:12 +01:00
Tor 0.2.1.13-alpha includes another big pile of minor bugfixes and
cleanups. We're finally getting close to a release candidate.
Possible fix for broken country settings in ExcludeExitNodes. It turns out that we weren't updating the _ExcludeExitNodesUnion set's country numbers when we reloaded (or first loaded!) the IP-to-country file. Spotted by Lark. Bugfix on 0.2.1.6-alpha. svn:r18575

2009-03-09 01:43:03 +01:00
help to people who didn't use the startup script. Resolves bug 863.
Retry circuits if the exit node is optional and nonexistant. Previously, when we had the chosen_exit set but marked optional, and we failed because we couldn't find an onion key for it, we'd just give up on the circuit. But what we really want to do is try again, without the forced exit node. Spotted by rovv. Another case of bug 752. I think this might be unreachable in our current code, but proposal 158 could change that. svn:r18451

be possible now, but will probably become feasible with proposal
158. Spotted by rovv. Fixes another case of bug 752.

been suppressing the bug since 0.1.2.10-alpha. Partial fix for
bug 929.
Add and use set/get_uint64 on onion tags. [bug 604; backportable] It seems that 64-bit Sparc Solaris demands 64-bit-aligned access to uint64_t, but does not 64-bit-align the stack-allocated char array we use for cpuworker tags.

Changes in version 0.2.0.34 - 2009-02-08
Tor 0.2.0.34 features several more security-related fixes. You should
upgrade, especially if you run an exit relay (remote crash) or a
directory authority (remote infinite loop), or you're on an older
(pre-XP) or not-recently-patched Windows (remote exploit).
This release marks end-of-life for Tor 0.1.2.x. Those Tor versions
have many known flaws, and nobody should be using them. You should
upgrade. If you're using a Linux or BSD and its packages are obsolete,
stop using those packages and upgrade anyway.
o Security fixes:
- Fix an infinite-loop bug on handling corrupt votes under certain
circumstances. Bugfix on 0.2.0.8-alpha.
- Fix a temporary DoS vulnerability that could be performed by
a directory mirror. Bugfix on 0.2.0.9-alpha; reported by lark.
- Avoid a potential crash on exit nodes when processing malformed
input. Remote DoS opportunity. Bugfix on 0.2.0.33.
- Do not accept incomplete ipv4 addresses (like 192.168.0) as valid.
Spec conformance issue. Bugfix on Tor 0.0.2pre27.
o Minor bugfixes:
- Fix compilation on systems where time_t is a 64-bit integer.

This fixes the last known case of bug 891, which could happen if two hosts, A and B, disagree about how long a circuit has been open, because of clock drift of some kind. Host A would then mark the connection as is_bad_for_new_circs when it got too old and open a new connection. In between when B receives a NETINFO cell on the new conn, and when B receives a conn cell on the new circuit, the new circuit will seem worse to B than the old one, and so B will mark it as is_bad_for_new_circs in the second or third loop of connection_or_group_set_badness().

one of them created a new connection with just the wrong timing,
the other might decide to deprecate the new connection erroneously.

Fix a race condition on nameserver reconfiguration. This resolves bug 526, wherein we would crash if the following events occurred in this order: A: We're an OR, and one of our nameservers goes down. B: We launch a probe to it to see if it's up again. (We do this hourly in steady-state.) C: Before the probe finishes, we reconfigure our nameservers, usually because we got a SIGHUP and the resolve.conf file changed. D: The probe reply comes back, or times out. (There is a five-second window for this, after B has happens). IOW, if one of our nameservers is down and our nameserver configuration has changed, there were 5 seconds per hour where HUPing the server was unsafe. Bugfix on 0.1.2.1-alpha.

Changes in version 0.2.0.33 - 2009-01-21
Tor 0.2.0.33 fixes a variety of bugs that were making relays less
useful to users. It also finally fixes a bug where a relay or client
that's been off for many days would take a long time to bootstrap.
This update also fixes an important security-related bug reported by
Ilja van Sprundel. You should upgrade. (We'll send out more details
about the bug once people have had some time to upgrade.)
o Security fixes:
- Fix a heap-corruption bug that may be remotely triggerable on
some platforms. Reported by Ilja van Sprundel.
o Major bugfixes:
- When a stream at an exit relay is in state "resolving" or
"connecting" and it receives an "end" relay cell, the exit relay
would silently ignore the end cell and not close the stream. If
the client never closes the circuit, then the exit relay never
closes the TCP connection. Bug introduced in Tor 0.1.2.1-alpha;
reported by "wood".
- When sending CREATED cells back for a given circuit, use a 64-bit
connection ID to find the right connection, rather than an addr:port
combination. Now that we can have multiple OR connections between
the same ORs, it is no longer possible to use addr:port to uniquely
identify a connection.
- Bridge relays that had DirPort set to 0 would stop fetching
descriptors shortly after startup, and then briefly resume
after a new bandwidth test and/or after publishing a new bridge
descriptor. Bridge users that try to bootstrap from them would
get a recent networkstatus but would get descriptors from up to
18 hours earlier, meaning most of the descriptors were obsolete
already. Reported by Tas; bugfix on 0.2.0.13-alpha.
- Prevent bridge relays from serving their 'extrainfo' document
to anybody who asks, now that extrainfo docs include potentially
sensitive aggregated client geoip summaries. Bugfix on
0.2.0.13-alpha.
- If the cached networkstatus consensus is more than five days old,
discard it rather than trying to use it. In theory it could be
useful because it lists alternate directory mirrors, but in practice
it just means we spend many minutes trying directory mirrors that
are long gone from the network. Also discard router descriptors as
we load them if they are more than five days old, since the onion
key is probably wrong by now. Bugfix on 0.2.0.x. Fixes bug 887.
o Minor bugfixes:
- Do not mark smartlist_bsearch_idx() function as ATTR_PURE. This bug
could make gcc generate non-functional binary search code. Bugfix
on 0.2.0.10-alpha.
- Build correctly on platforms without socklen_t.
- Compile without warnings on solaris.
- Avoid potential crash on internal error during signature collection.
Fixes bug 864. Patch from rovv.
- Correct handling of possible malformed authority signing key
certificates with internal signature types. Fixes bug 880.
Bugfix on 0.2.0.3-alpha.
- Fix a hard-to-trigger resource leak when logging credential status.
CID 349.
- When we can't initialize DNS because the network is down, do not
automatically stop Tor from starting. Instead, we retry failed
dns_init() every 10 minutes, and change the exit policy to reject
*:* until one succeeds. Fixes bug 691.
- Use 64 bits instead of 32 bits for connection identifiers used with
the controller protocol, to greatly reduce risk of identifier reuse.
- When we're choosing an exit node for a circuit, and we have
no pending streams, choose a good general exit rather than one that
supports "all the pending streams". Bugfix on 0.1.1.x. Fix by rovv.
- Fix another case of assuming, when a specific exit is requested,
that we know more than the user about what hosts it allows.
Fixes one case of bug 752. Patch from rovv.
- Clip the MaxCircuitDirtiness config option to a minimum of 10
seconds. Warn the user if lower values are given in the
configuration. Bugfix on 0.1.0.1-rc. Patch by Sebastian.
- Clip the CircuitBuildTimeout to a minimum of 30 seconds. Warn the
user if lower values are given in the configuration. Bugfix on
0.1.1.17-rc. Patch by Sebastian.
- Fix a memory leak when we decline to add a v2 rendezvous descriptor to
the cache because we already had a v0 descriptor with the same ID.
Bugfix on 0.2.0.18-alpha.
- Fix a race condition when freeing keys shared between main thread
and CPU workers that could result in a memory leak. Bugfix on
0.1.0.1-rc. Fixes bug 889.
- Send a valid END cell back when a client tries to connect to a
nonexistent hidden service port. Bugfix on 0.1.2.15. Fixes bug
840. Patch from rovv.
- Check which hops rendezvous stream cells are associated with to
prevent possible guess-the-streamid injection attacks from
intermediate hops. Fixes another case of bug 446. Based on patch
from rovv.
- If a broken client asks a non-exit router to connect somewhere,
do not even do the DNS lookup before rejecting the connection.
Fixes another case of bug 619. Patch from rovv.
- When a relay gets a create cell it can't decrypt (e.g. because it's
using the wrong onion key), we were dropping it and letting the
client time out. Now actually answer with a destroy cell. Fixes
bug 904. Bugfix on 0.0.2pre8.
o Minor bugfixes (hidden services):
- Do not throw away existing introduction points on SIGHUP. Bugfix on
0.0.6pre1. Patch by Karsten. Fixes bug 874.
o Minor features:
- Report the case where all signatures in a detached set are rejected
differently than the case where there is an error handling the
detached set.
- When we realize that another process has modified our cached
descriptors, print out a more useful error message rather than
triggering an assertion. Fixes bug 885. Patch from Karsten.
- Implement the 0x20 hack to better resist DNS poisoning: set the
case on outgoing DNS requests randomly, and reject responses that do
not match the case correctly. This logic can be disabled with the
ServerDNSRamdomizeCase setting, if you are using one of the 0.3%
of servers that do not reliably preserve case in replies. See
"Increased DNS Forgery Resistance through 0x20-Bit Encoding"
for more info.
- Check DNS replies for more matching fields to better resist DNS
poisoning.
- Never use OpenSSL compression: it wastes RAM and CPU trying to
compress cells, which are basically all encrypted, compressed, or
both.

Tor 0.2.1.10-alpha fixes two major bugs in bridge relays (one that
would make the bridge relay not so useful if it had DirPort set to 0,
and one that could let an attacker learn a little bit of information
about the bridge's users), and a bug that would cause your Tor relay
to ignore a circuit create request it can't decrypt (rather than reply
with an error). It also fixes a wide variety of other bugs.

thanks to Karsten.
- When we're sending non-EXTEND cells to the first hop in a circuit,
for example to use an encrypted directory connection, we don't need
to use RELAY_EARLY cells: the first hop knows what kind of cell
it is, and nobody else can even see the cell type. Conserving
RELAY_EARLY cells makes it easier to cannibalize circuits like
this later.
- Stop logging nameserver addresses in reverse order.
- If we are retrying a directory download slowly over and over, do
not automatically give up after the 254th failure. Bugfix on
0.2.1.9-alpha.
- Resume reporting accurate "stream end" reasons to the local control
port. They were lost in the changes for Proposal 148. Bugfix on
0.2.1.9-alpha.

When a stream at an exit relay is in state "resolving" or "connecting" and it receives an "end" relay cell, the exit relay would silently ignore the end cell and not close the stream.

2008-12-17 23:46:00 +01:00
- Give a better error message when an overzealous init script says

pairs. Partial implementation of proposal 157.
Implement proposal 148: Make client stream end reasons uniform. This patch makes every RELAY_COMMAND_END cell that we send pass through one of two functions: connection_edge_end and relay_send_end_cell_from_edge. Both of these functions check the circuit purpose, and change the reason to MISC if the circuit purpose means that it's for client use. svn:r17612
2008-12-12 21:30:42 +01:00
- Clients now never report any stream end reason except 'MISC'.
Implements proposal 148.

messages to that length ourselves, rather than relying on the
system to do it for us.

or for every cell. On systems where time() is a slow syscall,

2008-12-11 18:18:03 +01:00
Tor 0.2.0.32 fixes a major security problem in Debian and Ubuntu
packages (and maybe other packages) noticed by Theo de Raadt, fixes
a smaller security flaw that might allow an attacker to access local
services, further improves hidden service performance, and fixes a
variety of other issues.
and forward-port those svn:r17359
2008-11-22 06:14:12 +01:00
o Security fixes:
- The "User" and "Group" config options did not clear the
supplementary group entries for the Tor process. The "User" option
is now more robust, and we now set the groups to the specified
user's primary group. The "Group" option is now ignored. For more
detailed logging on credential switching, set CREDENTIAL_LOG_LEVEL
in common/compat.c to LOG_NOTICE or higher. Patch by Jacob Appelbaum
and Steven Murdoch. Bugfix on 0.0.2pre14. Fixes bug 848 and 857.
- The "ClientDNSRejectInternalAddresses" config option wasn't being
consistently obeyed: if an exit relay refuses a stream because its
exit policy doesn't allow it, we would remember what IP address
the relay said the destination address resolves to, even if it's
an internal IP address. Bugfix on 0.2.0.7-alpha; patch by rovv.
o Major bugfixes:
- Fix a DOS opportunity during the voting signature collection process
at directory authorities. Spotted by rovv. Bugfix on 0.2.0.x.
o Major bugfixes (hidden services):
- When fetching v0 and v2 rendezvous service descriptors in parallel,
we were failing the whole hidden service request when the v0
descriptor fetch fails, even if the v2 fetch is still pending and
might succeed. Similarly, if the last v2 fetch fails, we were
failing the whole hidden service request even if a v0 fetch is
still pending. Fixes bug 814. Bugfix on 0.2.0.10-alpha.
- When extending a circuit to a hidden service directory to upload a
rendezvous descriptor using a BEGIN_DIR cell, almost 1/6 of all
requests failed, because the router descriptor has not been
downloaded yet. In these cases, do not attempt to upload the
rendezvous descriptor, but wait until the router descriptor is
downloaded and retry. Likewise, do not attempt to fetch a rendezvous
descriptor from a hidden service directory for which the router
descriptor has not yet been downloaded. Fixes bug 767. Bugfix
on 0.2.0.10-alpha.
o Minor bugfixes:
- Fix several infrequent memory leaks spotted by Coverity.
- When testing for libevent functions, set the LDFLAGS variable
correctly. Found by Riastradh.
- Avoid a bug where the FastFirstHopPK 0 option would keep Tor from
bootstrapping with tunneled directory connections. Bugfix on
0.1.2.5-alpha. Fixes bug 797. Found by Erwin Lam.
- When asked to connect to A.B.exit:80, if we don't know the IP for A
and we know that server B rejects most-but-not all connections to
port 80, we would previously reject the connection. Now, we assume
the user knows what they were asking for. Fixes bug 752. Bugfix
on 0.0.9rc5. Diagnosed by BarkerJr.
- If we overrun our per-second write limits a little, count this as
having used up our write allocation for the second, and choke
outgoing directory writes. Previously, we had only counted this when
we had met our limits precisely. Fixes bug 824. Patch from by rovv.
Bugfix on 0.2.0.x (??).
- Remove the old v2 directory authority 'lefkada' from the default
list. It has been gone for many months.
- Stop doing unaligned memory access that generated bus errors on
sparc64. Bugfix on 0.2.0.10-alpha. Fixes bug 862.
- Make USR2 log-level switch take effect immediately. Bugfix on
0.1.2.8-beta.
o Minor bugfixes (controller):
- Make DNS resolved events into "CLOSED", not "FAILED". Bugfix on
0.1.2.5-alpha. Fix by Robert Hogan. Resolves bug 807.

2008-10-12 02:51:02 +02:00
Tor 0.2.1.6-alpha further improves performance and robustness of
hidden services, starts work on supporting per-country relay selection,
and fixes a variety of smaller issues.
Add patch 4 from Karsten for proposal 121, slightly modified. Karsten should definitely re-review the bits I changed. svn:r16955
2008-09-24 16:44:29 +02:00
o Major features:
- Implement proposal 121: make it possible to build hidden services
changelog cleanups. give 0.2.1.6-alpha a deadline. svn:r16995
2008-09-29 08:54:32 +02:00
that only certain clients are allowed to connect to. This is
enforced at several points, so that unauthorized clients are unable
to send INTRODUCE cells to the service, or even (depending on the
type of authentication) to learn introduction points. This feature
raises the bar for certain kinds of active attacks against hidden
services. Code by Karsten Loesing.
- Relays now store and serve v2 hidden service descriptors by default,
i.e., the new default value for HidServDirectoryV2 is 1. This is
the last step in proposal 114, which aims to make hidden service
lookups more reliable.
bump to 0.2.1.6-alpha, and note that the exclude*nodes config discussion hasn't finished. svn:r17011
2008-09-30 11:37:18 +02:00
- Start work to allow node restrictions to include country codes. The
syntax to exclude nodes in a country with country code XX is
"ExcludeNodes {XX}". Patch from Robert Hogan. It still needs some
refinement to decide what config options should take priority if
you ask to both use a particular node and exclude it.

2008-09-09 08:25:39 +02:00
o Major bugfixes:
- Fix a bug when parsing ports in tor_addr_port_parse() that caused
Tor to fail to start if you had it configured to use a bridge
relay. Fixes bug 809. Bugfix on 0.2.1.5-alpha.

requests failed, because the router descriptor had not been
downloaded yet. In these cases, we now wait until the router
descriptor is downloaded, and then retry. Likewise, clients
now skip over a hidden service directory if they don't yet have
its router descriptor, rather than futilely requesting it and
putting mysterious complaints in the logs. Fixes bug 767. Bugfix

descriptor fetch fails, even if the v2 fetch is still pending and
might succeed. Similarly, if the last v2 fetch fails, we were
failing the whole hidden service request even if a v0 fetch is
still pending. Fixes bug 814. Bugfix on 0.2.0.10-alpha.

these names should be in the questions section, not necessarily
in the answers section. Fixes bug 823. Bugfix on 0.2.1.5-alpha.
rearrange the changelog a bit more svn:r16996
2008-09-29 11:30:06 +02:00
o Minor features:
- Update to the "September 1 2008" ip-to-country file.
- Allow ports 465 and 587 in the default exit policy again. We had
rejected them in 0.1.0.15, because back in 2005 they were commonly
misconfigured and ended up as spam targets. We hear they are better
locked down these days.
- Use a lockfile to make sure that two Tor processes are not
simultaneously running with the same datadir.
- Serve the latest v3 networkstatus consensus via the control
port. Use "getinfo dir/status-vote/current/consensus" to fetch it.
- Better logging about stability/reliability calculations on directory
servers.
- Drop the requirement to have an open dir port for storing and
serving v2 hidden service descriptors.
- Directory authorities now serve a /tor/dbg-stability.txt URL to
help debug WFU and MTBF calculations.
- Implement most of Proposal 152: allow specialized servers to permit
single-hop circuits, and clients to use those servers to build
single-hop circuits when using a specialized controller. Patch
from Josh Albrecht. Resolves feature request 768.
Make tor-resolve take a -p port option in addition to the current host:port syntax. svn:r17002

Changes in version 0.2.0.31 - 2008-09-03
Tor 0.2.0.31 addresses two potential anonymity issues, starts to fix
a big bug we're seeing where in rare cases traffic from one Tor stream
gets mixed into another stream, and fixes a variety of smaller issues.
o Major bugfixes:
- Make sure that two circuits can never exist on the same connection
with the same circuit ID, even if one is marked for close. This
is conceivably a bugfix for bug 779. Bugfix on 0.1.0.4-rc.
- Relays now reject risky extend cells: if the extend cell includes
a digest of all zeroes, or asks to extend back to the relay that
sent the extend cell, tear down the circuit. Ideas suggested
by rovv.
- If not enough of our entry guards are available so we add a new
one, we might use the new one even if it overlapped with the
current circuit's exit relay (or its family). Anonymity bugfix
pointed out by rovv.
o Minor bugfixes:
- Recover 3-7 bytes that were wasted per memory chunk. Fixes bug
794; bug spotted by rovv. Bugfix on 0.2.0.1-alpha.
- Correctly detect the presence of the linux/netfilter_ipv4.h header
when building against recent kernels. Bugfix on 0.1.2.1-alpha.
- Pick size of default geoip filename string correctly on windows.
Fixes bug 806. Bugfix on 0.2.0.30.
- Make the autoconf script accept the obsolete --with-ssl-dir
option as an alias for the actually-working --with-openssl-dir
option. Fix the help documentation to recommend --with-openssl-dir.
Based on a patch by "Dave". Bugfix on 0.2.0.1-alpha.
- When using the TransPort option on OpenBSD, and using the User
option to change UID and drop privileges, make sure to open
/dev/pf before dropping privileges. Fixes bug 782. Patch from
Christopher Davis. Bugfix on 0.1.2.1-alpha.
- Try to attach connections immediately upon receiving a RENDEZVOUS2
or RENDEZVOUS_ESTABLISHED cell. This can save a second or two
on the client side when connecting to a hidden service. Bugfix
on 0.0.6pre1. Found and fixed by Christian Wilms; resolves bug 743.
- When closing an application-side connection because its circuit is
getting torn down, generate the stream event correctly. Bugfix on
0.1.2.x. Anonymous patch.

and here too svn:r16835
2008-09-10 21:08:46 +02:00
Tor 0.2.1.5-alpha moves us closer to handling IPv6 destinations, puts
in a lot of the infrastructure for adding authorization to hidden
services, lays the groundwork for having clients read their load
balancing information out of the networkstatus consensus rather than
the individual router descriptors, addresses two potential anonymity
issues, and fixes a variety of smaller issues.

o Major features:
r17641@31-33-44: nickm | 2008-08-05 16:07:53 -0400 Initial conversion of uint32_t addr to tor_addr_t addr in connection_t and related types.

2008-08-05 22:08:19 +02:00
- Convert many internal address representations to optionally hold
IPv6 addresses.
- Generate and accept IPv6 addresses in many protocol elements.

authorization data for hidden services at clients. The next
step is to actually access hidden services that perform client
authorization.
- More progress toward proposal 141: Network status consensus
documents and votes now contain bandwidth information for each
router and a summary of that router's exit policy. Eventually this
will be used by clients so that they do not have to download every
known descriptor before building circuits.

might cause exit relays to corrupt streams they send back; allows
address patterns (e.g. 255.128.0.0/16) to appear in ExcludeNodes and
ExcludeExitNodes config options; and fixes a big pile of bugs.

- Implement most of proposal 110: The first K cells to be sent
along a circuit are marked as special "early" cells; only K "early"
cells will be allowed. Once this code is universal, we can block
certain kinds of DOS attack by requiring that EXTEND commands must
be sent using an "early" cell.

o Major bugfixes:
- If you have more than one bridge but don't know their keys,
you would only launch a request for the descriptor of the first one
on your list. (Tor considered launching requests for the others, but
found that it already had a connection on the way for $0000...0000
so it didn't open another.) Bugfix on 0.2.0.x.
- If you have more than one bridge but don't know their keys, and the
connection to one of the bridges failed, you would cancel all
pending bridge connections. (After all, they all have the same
digest.) Bugfix on 0.2.0.x.
- When a hidden service was trying to establish an introduction point,
and Tor had built circuits preemptively for such purposes, we
were ignoring all the preemptive circuits and launching a new one
instead. Bugfix on 0.2.0.14-alpha.
- When a hidden service was trying to establish an introduction point,
and Tor *did* manage to reuse one of the preemptively built
circuits, it didn't correctly remember which one it used,
so it asked for another one soon after, until there were no
more preemptive circuits, at which point it launched one from
scratch. Bugfix on 0.0.9.x.
- Make directory servers include the X-Your-Address-Is: http header in
their responses even for begin_dir conns. Now clients who only
ever use begin_dir connections still have a way to learn their IP
address. Fixes bug 737; bugfix on 0.2.0.22-rc. Reported by goldy.

- Start sending "count" and "recommendation" key/value pairs in
bootstrap problem status events, so the controller can hear about
problems even before Tor decides they're worth reporting for sure.

put in some of the release summaries svn:r15535
2008-06-28 06:23:26 +02:00
Tor 0.2.1.1-alpha fixes a lot of memory fragmentation problems that
were making the Tor process bloat especially on Linux; makes our TLS
handshake blend in better; sends "bootstrap phase" status events to
the controller, so it can keep the user informed of progress (and
problems) fetching directory information and establishing circuits;
and adds a variety of smaller features.

o Major features:
make some of the 0.2.1.1-alpha changelog items more prominent svn:r15186
2008-06-13 07:13:22 +02:00
- More work on making our TLS handshake blend in: modify the list
of ciphers advertised by OpenSSL in client mode to even more
closely resemble a common web browser. We cheat a little so that
we can advertise ciphers that the locally installed OpenSSL doesn't
know about.

2008-06-13 06:26:05 +02:00
- Start sending "bootstrap phase" status events to the controller,
so it can keep the user informed of progress fetching directory
information and establishing circuits. Also inform the controller
if we think we're stuck at a particular bootstrap phase. Implements
proposal 137.
make some of the 0.2.1.1-alpha changelog items more prominent svn:r15186
2008-06-13 07:13:22 +02:00
- Resume using OpenSSL's RAND_poll() for better (and more portable)
cross-platform entropy collection again. We used to use it, then
stopped using it because of a bug that could crash systems that
called RAND_poll when they had a lot of fds open. It looks like the
bug got fixed in late 2006. Our new behavior is to call RAND_poll()
at startup, and to call RAND_poll() when we reseed later only if
we have a non-buggy OpenSSL version.
o Major bugfixes:
- When we choose to abandon a new entry guard because we think our
older ones might be better, close any circuits pending on that

faster when our network is down and then comes back. Bugfix on

o Memory fixes and improvements:
- Add a malloc_good_size implementation to OpenBSD_malloc_linux.c,
to avoid unused RAM in buffer chunks and memory pools.
- Speed up parsing and cut down on memory fragmentation by using
stack-style allocations for parsing directory objects. Previously,
this accounted for over 40% of allocations from within Tor's code
on a typical directory cache.
- Use a Bloom filter rather than a digest-based set to track which
descriptors we need to keep around when we're cleaning out old
router descriptors. This speeds up the computation significantly,
and may reduce fragmentation.
- Reduce the default smartlist size from 32 to 16; it turns out that
most smartlists hold around 8-12 elements tops.
- Make dumpstats() log the fullness and size of openssl-internal
buffers.
- If the user has applied the experimental SSL_MODE_RELEASE_BUFFERS
patch to their OpenSSL, turn it on to save memory on servers. This
patch will (with any luck) get included in a mainline distribution
before too long.
make some of the 0.2.1.1-alpha changelog items more prominent svn:r15186
2008-06-13 07:13:22 +02:00
- Never use OpenSSL compression: it wastes RAM and CPU trying to
compress cells, which are basically all encrypted, compressed,
or both.

2008-02-27 20:19:34 +01:00

Tor 0.2.0.28-rc fixes an anonymity-related bug, fixes a hidden-service
performance bug, and fixes a bunch of smaller bugs.
forward-port the 0.2.0.28-rc changelog svn:r15194
2008-06-13 08:40:36 +02:00
o Anonymity fixes:
- Fix a bug where, when we were choosing the 'end stream reason' to
put in our relay end cell that we send to the exit relay, Tor
clients on Windows were sometimes sending the wrong 'reason'. The
anonymity problem is that exit relays may be able to guess whether
the client is running Windows, thus helping partition the anonymity
set. Down the road we should stop sending reasons to exit relays,
or otherwise prevent future versions of this bug.
o Major bugfixes:
- While setting up a hidden service, some valid introduction circuits
were overlooked and abandoned. This might be the reason for
the long delay in making a hidden service available. Bugfix on
When establishing a hidden service, introduction points that originate from cannibalized circuits are completely ignored and not included in rendezvous service descriptors. Bugfix on 0.2.0.14-alpha. Backport candidate. svn:r15332

o Minor features:

- Run 'make test' as part of 'make dist', so we stop releasing so
many development snapshots that fail their unit tests.
o Minor bugfixes:
- When we're checking if we have enough dir info for each relay
to begin establishing circuits, make sure that we actually have
the descriptor listed in the consensus, not just any descriptor.

2008-06-28 06:23:26 +02:00
Tor 0.2.0.27-rc adds a few features we left out of the earlier
release candidates. In particular, we now include an IP-to-country
GeoIP database, so controllers can easily look up what country a
given relay is in, and so bridge relays can give us some sanitized
summaries about which countries are making use of bridges. (See proposal
126-geoip-fetching.txt for details.)
forward-port the 0.2.0.27-rc changelog svn:r14967
2008-06-05 08:27:58 +02:00
o Major features:
- Include an IP-to-country GeoIP file in the tarball, so bridge
relays can report sanitized summaries of the usage they're seeing.
o Minor features:
- Add a "PURPOSE=" argument to "STREAM NEW" events, as suggested by
Robert Hogan. Fixes the first part of bug 681.
- Make bridge authorities never serve extrainfo docs.
- Add support to detect Libevent versions in the 1.4.x series
on mingw.
- Fix build on gcc 4.3 with --enable-gcc-warnings set.
- Include a new contrib/tor-exit-notice.html file that exit relay
operators can put on their website to help reduce abuse queries.
o Minor bugfixes:
- When tunneling an encrypted directory connection, and its first
circuit fails, do not leave it unattached and ask the controller
to deal. Fixes the second part of bug 681.
- Make bridge authorities correctly expire old extrainfo documents
from time to time.

Changes in version 0.2.0.26-rc - 2008-05-13
Tor 0.2.0.26-rc fixes a major security vulnerability caused by a bug
in Debian's OpenSSL packages. All users running any 0.2.0.x version
should upgrade, whether they're running Debian or not.
o Major security fixes:
- Use new V3 directory authority keys on the tor26, gabelmoo, and
moria1 V3 directory authorities. The old keys were generated with
a vulnerable version of Debian's OpenSSL package, and must be
considered compromised. Other authorities' keys were not generated
with an affected version of OpenSSL.
o Major bugfixes:
- List authority signatures as "unrecognized" based on DirServer
lines, not on cert cache. Bugfix on 0.2.0.x.
o Minor features:
- Add a new V3AuthUseLegacyKey option to make it easier for
authorities to change their identity keys if they have to.

Changes in version 0.2.0.25-rc - 2008-04-23
Tor 0.2.0.25-rc makes Tor work again on OS X and certain BSDs.
o Major bugfixes:
- Remember to initialize threading before initializing logging.
Otherwise, many BSD-family implementations will crash hard on
startup. Fixes bug 671. Bugfix on 0.2.0.24-rc.
o Minor bugfixes:
- Authorities correctly free policies on bad servers on
exit. Fixes bug 672. Bugfix on 0.2.0.x.
Changes in version 0.2.0.24-rc - 2008-04-22
Tor 0.2.0.24-rc adds dizum (run by Alex de Joode) as the new sixth
v3 directory authority, makes relays with dynamic IP addresses and no
DirPort notice more quickly when their IP address changes, fixes a few
rare crashes and memory leaks, and fixes a few other miscellaneous bugs.
o New directory authorities:
- Take lefkada out of the list of v3 directory authorities, since
it has been down for months.
- Set up dizum (run by Alex de Joode) as the new sixth v3 directory
authority.
o Major bugfixes:
- Detect address changes more quickly on non-directory mirror
relays. Bugfix on 0.2.0.18-alpha; fixes bug 652.
o Minor features (security):
- Reject requests for reverse-dns lookup of names that are in
a private address space. Patch from lodger.
- Non-exit relays no longer allow DNS requests. Fixes bug 619. Patch
from lodger.
o Minor bugfixes (crashes):
- Avoid a rare assert that can trigger when Tor doesn't have much
directory information yet and it tries to fetch a v2 hidden
service descriptor. Fixes bug 651, reported by nwf.
- Initialize log mutex before initializing dmalloc. Otherwise,
running with dmalloc would crash. Bugfix on 0.2.0.x-alpha.
- Use recursive pthread mutexes in order to avoid deadlock when
logging debug-level messages to a controller. Bug spotted by nwf,
bugfix on 0.2.0.16-alpha.
o Minor bugfixes (resource management):
- Keep address policies from leaking memory: start their refcount
at 1, not 2. Bugfix on 0.2.0.16-alpha.
- Free authority certificates on exit, so they don't look like memory
leaks. Bugfix on 0.2.0.19-alpha.
- Free static hashtables for policy maps and for TLS connections on
shutdown, so they don't look like memory leaks. Bugfix on 0.2.0.x.
- Avoid allocating extra space when computing consensuses on 64-bit
platforms. Bug spotted by aakova.
o Minor bugfixes (misc):
- Do not read the configuration file when we've only been told to
generate a password hash. Fixes bug 643. Bugfix on 0.0.9pre5. Fix
based on patch from Sebastian Hahn.
- Exit relays that are used as a client can now reach themselves
using the .exit notation, rather than just launching an infinite
pile of circuits. Fixes bug 641. Reported by Sebastian Hahn.
- When attempting to open a logfile fails, tell us why.
- Fix a dumb bug that was preventing us from knowing that we should
preemptively build circuits to handle expected directory requests.
Fixes bug 660. Bugfix on 0.1.2.x.
- Warn less verbosely about clock skew from netinfo cells from
untrusted sources. Fixes bug 663.
- Make controller stream events for DNS requests more consistent,
by adding "new stream" events for DNS requests, and removing
spurious "stream closed" events" for cached reverse resolves.
Patch from mwenge. Fixes bug 646.
- Correctly notify one-hop connections when a circuit build has
failed. Possible fix for bug 669. Found by lodger.

certain censored countries by default again.

o Minor bugfixes (on 0.1.2.x):
- Generate "STATUS_SERVER" events rather than misspelled
"STATUS_SEVER" events. Caught by mwenge.
- When counting the number of bytes written on a TLS connection,
look at the BIO actually used for writing to the network, not
at the BIO used (sometimes) to buffer data for the network.
Looking at different BIOs could result in write counts on the
order of ULONG_MAX. Fixes bug 614.

o Minor bugfixes (on 0.2.0.x):
- Downgrade "sslv3 alert handshake failure" message to INFO.
- If we set RelayBandwidthRate and RelayBandwidthBurst very high but
left BandwidthRate and BandwidthBurst at the default, we would be
silently limited by those defaults. Now raise them to match the
RelayBandwidth* values.
- Fix the SVK version detection logic to work correctly on a branch.
- Make --enable-openbsd-malloc work correctly on Linux with alpha
CPUs. Fixes bug 625.
- Logging functions now check that the passed severity is sane.
- Use proper log levels in the testsuite call of
get_interface_address6().
- When using a nonstandard malloc, do not use the platform values for
HAVE_MALLOC_GOOD_SIZE or HAVE_MALLOC_USABLE_SIZE.
- Make the openbsd malloc code use 8k pages on alpha CPUs and
16k pages on ia64.
- Detect mismatched page sizes when using --enable-openbsd-malloc.
- Avoid double-marked-for-close warning when certain kinds of invalid
.in-addr.arpa addresses are passed to the DNSPort. Part of a fix
for bug 617. Bugfix on 0.2.0.1-alpha.
- Make sure that the "NULL-means-reject *:*" convention is followed by
all the policy manipulation functions, avoiding some possible crash
bugs. Bug found by lodger. Bugfix on 0.2.0.16-alpha.

- The control port should declare that it requires password auth
when HashedControlSessionPassword is set too. Patch from Matt Edman;
bugfix on 0.2.0.20-rc. Fixes bug 615.
- Downgrade assert in connection_buckets_decrement() to a log message.
This may help us solve bug 614, and in any case will make its
symptoms less severe. Bugfix on 0.2.0.20-rc. Reported by fredzupy.
- We were sometimes miscounting the number of bytes read from the
network, causing our rate limiting to not be followed exactly.
Bugfix on 0.2.0.16-alpha. Reported by lodger.
o Minor bugfixes:
When a relay gets a create cell it can't decrypt (e.g. because it's using the wrong onion key), we were dropping it and letting the client time out. Now actually answer with a destroy cell. Bugfix on 0.0.2pre8. svn:r17970

2008-02-26 04:11:37 +01:00
Tor 0.2.0.20-rc is the first release candidate for the 0.2.0 series. It
makes more progress towards normalizing Tor's TLS handshake, makes
hidden services work better again, helps relays bootstrap if they don't
know their IP address, adds optional support for linking in openbsd's
allocator or tcmalloc, allows really fast relays to scale past 15000
sockets, and fixes a bunch of minor bugs reported by Veracode.
Start choosing which bridge to use proportional to its advertised bandwidth, rather than uniformly at random. This should speed up Tor for bridge users. Also do this for people who set StrictEntryNodes. svn:r13486

bump to 0.2.0.20-rc svn:r13715
2008-02-25 01:39:58 +01:00
proposal 105. The new handshake is meant to be harder for censors
to fingerprint, and it adds the ability to detect certain kinds of
man-in-the-middle traffic analysis attacks. The version negotiation
feature will allow us to improve Tor's link protocol more safely
in the future.
- Choose which bridge to use proportional to its advertised bandwidth,
rather than uniformly at random. This should speed up Tor for
bridge users. Also do this for people who set StrictEntryNodes.
- When a TrackHostExits-chosen exit fails too many times in a row,
stop using it. Bugfix on 0.1.2.x; fixes bug 437.

- When counting the number of open sockets, count not only the number
of sockets we have received from the socket() call, but also
the number we've gotten from accept() and socketpair(). This bug
made us fail to count all sockets that we were using for incoming
connections. Bugfix on 0.2.0.x.
- Fix code used to find strings within buffers, when those strings
are not in the first chunk of the buffer. Bugfix on 0.2.0.x.
- Fix potential segfault when parsing HTTP headers. Bugfix on 0.2.0.x.
- Add a new __HashedControlSessionPassword option for controllers
to use for one-off session password hashes that shouldn't get
saved to disk by SAVECONF --- Vidalia users were accumulating a
pile of HashedControlPassword lines in their torrc files, one for
each time they had restarted Tor and then clicked Save. Make Tor
automatically convert "HashedControlPassword" to this new option but
only when it's given on the command line. Partial fix for bug 586.

guessing more robust, and generally fixes a lot of bugs in preparation
for calling the 0.2.0 branch stable.

o Major features:
- Do not include recognizeable strings in the commonname part of
Tor's x509 certificates.
o Major bugfixes:
- If we're a relay, avoid picking ourselves as an introduction point,
a rendezvous point, or as the final hop for internal circuits. Bug
reported by taranis and lodger. Bugfix on 0.1.2.x.
- Patch from "Andrew S. Lists" to catch when we contact a directory
mirror at IP address X and he says we look like we're coming from
IP address X. Bugfix on 0.1.2.x.
o Minor features (security):
- Be more paranoid about overwriting sensitive memory on free(),
as a defensive programming tactic to ensure forward secrecy.

Changes in version 0.1.2.19 - 2008-01-17
Tor 0.1.2.19 fixes a huge memory leak on exit relays, makes the default
exit policy a little bit more conservative so it's safer to run an
exit relay on a home system, and fixes a variety of smaller issues.
o Security fixes:
- Exit policies now reject connections that are addressed to a
relay's public (external) IP address too, unless
ExitPolicyRejectPrivate is turned off. We do this because too
many relays are running nearby to services that trust them based
on network address.
o Major bugfixes:
- When the clock jumps forward a lot, do not allow the bandwidth
buckets to become negative. Fixes bug 544.
- Fix a memory leak on exit relays; we were leaking a cached_resolve_t
on every successful resolve. Reported by Mike Perry.
- Purge old entries from the "rephist" database and the hidden
service descriptor database even when DirPort is zero.
- Stop thinking that 0.1.2.x directory servers can handle "begin_dir"
requests. Should ease bugs 406 and 419 where 0.1.2.x relays are
crashing or mis-answering these requests.
- When we decide to send a 503 response to a request for servers, do
not then also send the server descriptors: this defeats the whole
purpose. Fixes bug 539.
o Minor bugfixes:
- Changing the ExitPolicyRejectPrivate setting should cause us to
rebuild our server descriptor.
- Fix handling of hex nicknames when answering controller requests for
networkstatus by name, or when deciding whether to warn about
unknown routers in a config option. (Patch from mwenge.)
- Fix a couple of hard-to-trigger autoconf problems that could result
in really weird results on platforms whose sys/types.h files define
nonstandard integer types.
- Don't try to create the datadir when running --verify-config or
--hash-password. Resolves bug 540.
- If we were having problems getting a particular descriptor from the
directory caches, and then we learned about a new descriptor for
that router, we weren't resetting our failure count. Reported
by lodger.
- Although we fixed bug 539 (where servers would send HTTP status 503
responses _and_ send a body too), there are still servers out there
that haven't upgraded. Therefore, make clients parse such bodies
when they receive them.
- Run correctly on systems where rlim_t is larger than unsigned long.
This includes some 64-bit systems.
- Run correctly on platforms (like some versions of OS X 10.5) where
the real limit for number of open files is OPEN_FILES, not rlim_max
from getrlimit(RLIMIT_NOFILES).
- Avoid a spurious free on base64 failure.
- Avoid segfaults on certain complex invocations of
router_get_by_hexdigest().
- Fix rare bug on REDIRECTSTREAM control command when called with no
port set: it could erroneously report an error when none had
happened.

Tor 0.2.0.14-alpha and 0.2.0.15-alpha fix a bunch of bugs with the
features added in 0.2.0.13-alpha.
Fix several remotely triggerable asserts based on DirPort requests for a v2 or v3 networkstatus object before we were prepared. This was particularly bad for 0.2.0.13 and later bridge relays, who would never have a v2 networkstatus and would thus always crash when used. Bugfixes on 0.2.0.x. Estimate the v3 networkstatus size more accurately, rather than estimating it at zero bytes and giving it artificially high priority compared to other directory requests.

where Tor is blocked.

snapshot summaries svn:r12523
2007-11-17 08:15:56 +01:00
This tenth development snapshot adds a third v3 directory authority
run by Mike Perry, adds most of Karsten Loesing's new hidden service
descriptor format, fixes a bad crash bug and new bridge bugs introduced
in 0.2.0.9-alpha, fixes many bugs with the v3 directory implementation,
fixes some minor memory leaks in previous 0.2.0.x snapshots, and
addresses many more minor issues.
Set up ides (run by Mike Perry) as the third v3 directory authority. svn:r12423
2007-11-07 22:20:45 +01:00
o New directory authorities:
- Set up ides (run by Mike Perry) as the third v3 directory authority.
Separate "SOCKS_COMMAND_CONNECT_DIR" into two flags in edge_connection_t: want_onehop if it must attach to a circuit with only one hop (e.g. for the current tunnelled connections that use begin_dir), and use_begindir if we mean to use a BEGIN_DIR relay command to establish the stream rather than the normal BEGIN. Now we can make anonymized begin_dir connections for (e.g.) more secure hidden service posting and fetching. svn:r12244
2007-10-28 09:16:19 +01:00
o Major features:
start to muck with the 0.2.0.10-alpha changelog svn:r12421
2007-11-07 20:38:08 +01:00
- Allow tunnelled directory connections to ask for an encrypted
"begin_dir" connection or an anonymized "uses a full Tor circuit"
connection independently. Now we can make anonymized begin_dir
connections for (e.g.) more secure hidden service posting and
fetching.
- More progress on proposal 114: code from Karsten Loesing to
implement new hidden service descriptor format.
Raise the default BandwidthRate/BandwidthBurst to 5MB/10MB, to accommodate the growing number of servers that use the default and are reaching it. svn:r12364
2007-11-03 23:08:52 +01:00
- Raise the default BandwidthRate/BandwidthBurst to 5MB/10MB, to
accommodate the growing number of servers that use the default
and are reaching it.

2007-11-10 08:03:05 +01:00
- Directory authorities use a new formula for selecting which nodes
to advertise as Guards: they must be in the top 7/8 in terms of
how long we have known about them, and above the median of those
nodes in terms of weighted fractional uptime.
bump to 0.2.0.10-alpha svn:r12455
2007-11-10 08:26:56 +01:00
- Make "not enough dir info yet" warnings describe *why* Tor feels
it doesn't have enough directory info yet.
Separate "SOCKS_COMMAND_CONNECT_DIR" into two flags in edge_connection_t: want_onehop if it must attach to a circuit with only one hop (e.g. for the current tunnelled connections that use begin_dir), and use_begindir if we mean to use a BEGIN_DIR relay command to establish the stream rather than the normal BEGIN. Now we can make anonymized begin_dir connections for (e.g.) more secure hidden service posting and fetching. svn:r12244

no longer work for clients.

2007-11-04 03:36:09 +01:00
o Major bugfixes (v3 dir, bugfixes on 0.2.0.9-alpha):
start to muck with the 0.2.0.10-alpha changelog svn:r12421
2007-11-07 20:38:08 +01:00
- When the consensus lists a router descriptor that we previously were
mirroring, but that we considered non-canonical, reload the
descriptor as canonical. This fixes bug 543 where Tor servers
would start complaining after a few days that they don't have
enough directory information to build a circuit.

2007-11-04 03:36:09 +01:00
considering replacement when the new certs _didn't_ help.
- Fix an assert error on startup if we didn't already have the
consensus and certs cached in our datadirectory: we were caching
the consensus in consensus_waiting_for_certs but then free'ing it
right after.
- Avoid sending a request for "keys/fp" (for which we'll get a 400 Bad
Request) if we need more v3 certs but we've already got pending
requests for all of them.

2007-10-27 00:50:40 +02:00
o Minor features:
Set up ides (run by Mike Perry) as the third v3 directory authority. svn:r12423
2007-11-07 22:20:45 +01:00
- Clients now hold circuitless TLS connections open for 1.5 times
bump to 0.2.0.10-alpha svn:r12455
2007-11-10 08:26:56 +01:00
MaxCircuitDirtiness (15 minutes), since it is likely that they'll
rebuild a new circuit over them within that timeframe. Previously,
they held them open only for KeepalivePeriod (5 minutes).
- Use "If-Modified-Since" to avoid retrieving consensus
networkstatuses that we already have.
r16247@catbus: nickm | 2007-10-28 19:38:00 -0400 Add changelog for last entry svn:r12260
2007-10-29 00:44:55 +01:00
- When we have no consensus, check FallbackNetworkstatusFile (defaults
to $PREFIX/share/tor/fallback-consensus) for a consensus. This way
we start knowing some directory caches.
r16278@catbus: nickm | 2007-10-30 09:46:28 -0400 Accept future networkstatus documents, but warn about skew when we get them. svn:r12282
2007-10-30 16:17:01 +01:00

cleanups in the changelog, plus ask nickm a question svn:r12363
2007-11-03 23:06:56 +01:00
- Improve skew reporting: try to give the user a better log message
about how skewed they are, and how much this matters.
- When we have a certificate for an authority, believe that
certificate's claims about the authority's IP address.
r16322@catbus: nickm | 2007-11-01 00:26:15 -0400 Implement --quiet. svn:r12306
2007-11-01 05:38:43 +01:00
- New --quiet command-line option to suppress the default console log.
Good in combination with --hash-password.
r16326@catbus: nickm | 2007-11-01 00:56:45 -0400 As an authority, send back an X-Descriptor-Not-New header when we accept but do not store a descriptor. Partial implementation of fix for bug 535. svn:r12310
2007-11-01 06:01:24 +01:00
- Authorities send back an X-Descriptor-Not-New header in response to
an accepted-but-discarded descriptor upload. Partially implements
fix for bug 535.
r16523@catbus: nickm | 2007-11-07 11:35:49 -0500 Improve "tls error. breaking" message a little. svn:r12411
2007-11-07 17:37:08 +01:00
- Make the log message for "tls error. breaking." more useful.

2007-11-08 17:19:04 +01:00
- Better log messages about certificate downloads, to attempt to
track down the second incarnation of bug 546.
r16279@catbus: nickm | 2007-10-30 11:14:29 -0400 Improved skew reporting: "You are 365 days in the duture" is more useful than "You are 525600 minutes in the future". Also, when we get something that proves we are at least an hour in the past, tell the controller "CLOCK_SKEW MIN_SKEW=-3600" rather than just "CLOCK_SKEW" svn:r12283

2007-11-04 01:15:42 +01:00
o Minor features (bridges):
- If bridge users set UpdateBridgesFromAuthority, but the digest
they ask for is a 404 from the bridge authority, they now fall
back to trying the bridge directly.
- Bridges now use begin_dir to publish their server descriptor to
the bridge authority, even when they haven't set TunnelDirConns.

Changes in version 0.1.2.18 - 2007-10-28
Tor 0.1.2.18 fixes many problems including crash bugs, problems with
hidden service introduction that were causing huge delays, and a big
bug that was causing some servers to disappear from the network status
lists for a few hours each day.
o Major bugfixes (crashes):
- If a connection is shut down abruptly because of something that
happened inside connection_flushed_some(), do not call
connection_finished_flushing(). Should fix bug 451:
"connection_stop_writing: Assertion conn->write_event failed"
Bugfix on 0.1.2.7-alpha.
- Fix possible segfaults in functions called from
rend_process_relay_cell().
o Major bugfixes (hidden services):
- Hidden services were choosing introduction points uniquely by
hexdigest, but when constructing the hidden service descriptor
they merely wrote the (potentially ambiguous) nickname.
- Clients now use the v2 intro format for hidden service
connections: they specify their chosen rendezvous point by identity
digest rather than by (potentially ambiguous) nickname. These
changes could speed up hidden service connections dramatically.
o Major bugfixes (other):
- Stop publishing a new server descriptor just because we get a
HUP signal. This led (in a roundabout way) to some servers getting
dropped from the networkstatus lists for a few hours each day.
- When looking for a circuit to cannibalize, consider family as well
as identity. Fixes bug 438. Bugfix on 0.1.0.x (which introduced
circuit cannibalization).
- When a router wasn't listed in a new networkstatus, we were leaving
the flags for that router alone -- meaning it remained Named,
Running, etc -- even though absence from the networkstatus means
that it shouldn't be considered to exist at all anymore. Now we
clear all the flags for routers that fall out of the networkstatus
consensus. Fixes bug 529.
o Minor bugfixes:
- Don't try to access (or alter) the state file when running
--list-fingerprint or --verify-config or --hash-password. Resolves
bug 499.
- When generating information telling us how to extend to a given
router, do not try to include the nickname if it is
absent. Resolves bug 467.
- Fix a user-triggerable segfault in expand_filename(). (There isn't
a way to trigger this remotely.)
- When sending a status event to the controller telling it that an

OR address is reachable, set the port correctly. (Previously we
forward-port the 0.1.2.18 entries svn:r12465
2007-11-11 01:33:53 +01:00
were reporting the dir port.)
- Fix a minor memory leak whenever a controller sends the PROTOCOLINFO
command. Bugfix on 0.1.2.17.
- When loading bandwidth history, do not believe any information in
the future. Fixes bug 434.
- When loading entry guard information, do not believe any information
in the future.
- When we have our clock set far in the future and generate an
onion key, then re-set our clock to be correct, we should not stop
the onion key from getting rotated.
- On some platforms, accept() can return a broken address. Detect
this more quietly, and deal accordingly. Fixes bug 483.
- It's not actually an error to find a non-pending entry in the DNS
cache when canceling a pending resolve. Don't log unless stuff
is fishy. Resolves bug 463.
- Don't reset trusted dir server list when we set a configuration
option. Patch from Robert Hogan.

This ninth development snapshot switches clients to the new v3 directory
system; allows servers to be listed in the network status even when they
have the same nickname as a registered server; and fixes many other
bugs including a big one that was causing some servers to disappear
from the network status lists for a few hours each day.

of v2 networkstatus documents. Clients and caches now base their
opinions about routers on these consensus documents. Clients only
download router descriptors listed in the consensus.
- Authorities now list servers who have the same nickname as
a different named server, but list them with a new flag,

"Unnamed". Now we can list servers that happen to pick the same
nickname as a server that registered two years ago and then
disappeared. Partially implements proposal 122.

Running, etc -- even though absence from the networkstatus means
that it shouldn't be considered to exist at all anymore. Now we

- Reattempt certificate downloads immediately on failure, as long as
we haven't failed a threshold number of times yet.

2007-10-24 21:53:11 +02:00
- Delay retrying consensus downloads while we're downloading
certificates to verify the one we just got. Also, count getting a
consensus that we already have (or one that isn't valid) as a failure,
and count failing to get the certificates after 20 minutes as a
failure.

than 28 days unmodified, then most likely it's a leftover from
when we upgraded to 0.2.0.8-alpha. Remove it. It has no good
routers anyway.
- When we (as a cache) download a descriptor because it was listed
in a consensus, remember when the consensus was supposed to expire,
and don't expire the descriptor until then.

- Don't try to launch new descriptor downloads quite so often when we
already have enough directory information to build circuits.
- Base64 decoding was actually showing up on our profile when parsing
the initial descriptor file; switch to an in-process all-at-once
implementation that's about 3.5x times faster than calling out to
OpenSSL.

- When we discard a vote as a duplicate, do not report this as
an error.

- Treat missing v3 keys or certificates as an error when running as a

2007-10-24 14:23:49 +02:00
- When we're configured to be a v3 authority, but we're only listed
as a non-v3 authority in our DirServer line for ourself, correct
the listing.
- If an authority doesn't have a qualified hostname, just put
its address in the vote. This fixes the problem where we referred to
"moria on moria:9031."
r15961@catbus: nickm | 2007-10-19 12:40:15 -0400 Learn the difference between "mismatched vote digest" and "mismatched vote times": the latter is more informative. svn:r12049

2007-10-19 20:56:30 +02:00
- Fix a small memory leak when computing a consensus.
When there's no concensus, we were forming a vote every 30 minutes, but writing the "valid-after" line in our vote based on our configured V3AuthVotingInterval: so unless the intervals matched up, we immediately rejected our own vote because it didn't start at the voting interval that caused us to construct a vote. This caused log entries like: Oct 23 01:16:16.303 [notice] Choosing expected valid-after time as 2007-10-23 05:30:00: consensus_set=0, interval=1800 ...

Bugfix on r7072, which turned out to basically be a no-op: Respond to INT and TERM SIGNAL commands before we execute the signal, in case the signal shuts us down. We had a patch in 0.1.2.1-alpha that tried to do this by queueing the response on the connection's buffer before shutting down, but that really isn't the same thing. Bug located by Matt Edman.

This eighth development snapshot fixes a crash bug that's been bothering
us since February 2007, lets bridge authorities store a list of bridge
descriptors they've seen, gets v3 directory voting closer to working,
starts caching v3 directory consensus documents on directory mirrors,
and fixes a variety of smaller issues including some minor memory leaks.

2007-10-11 01:40:21 +02:00
o Major features (router descriptor cache):
- Store routers in a file called cached-descriptors instead of in
cached-routers. Initialize cached-descriptors from cached-routers
if the old format is around. The new format allows us to store
annotations along with descriptors.
muck with the changelog some more svn:r11898
2007-10-12 20:55:30 +02:00
- Use annotations to record the time we received each descriptor, its
source, and its purpose.
Disable the SETROUTERPURPOSE controller command: it is now obsolete. svn:r11891
2007-10-12 00:19:47 +02:00
- Disable the SETROUTERPURPOSE controller command: it is now
obsolete.
Controllers should now specify cache=no or cache=yes when using the +POSTDESCRIPTOR command. svn:r11892

2007-10-11 01:40:21 +02:00
- Bridge authorities now write bridge descriptors to disk, meaning
we can export them to other programs and begin distributing them
to blocked users.

o Major features (directory authorities):

2007-10-11 01:40:21 +02:00
- When a v3 authority is missing votes or signatures, it now tries
to fetch them.
r15630@catbus: nickm | 2007-10-10 13:39:44 -0400 Save weighted-fractional-uptime to disk as well as MTBF. Bump the version on rouer-stability: downgrading to versions earlier than this one will lose your WFU data. svn:r11835
2007-10-10 19:48:58 +02:00
- Directory authorities track weighted fractional uptime as well as
weighted mean-time-between failures. WFU is suitable for deciding
whether a node is "usually up", while MTBF is suitable for deciding
rough up the changelog svn:r11856
2007-10-11 01:40:21 +02:00
whether a node is "likely to stay up." We need both, because
"usually up" is a good requirement for guards, while "likely to
stay up" is a good requirement for long-lived connections.

o Major features (v3 directory system):
muck with the changelog some more svn:r11898
2007-10-12 20:55:30 +02:00
- Caches now download v3 network status documents as needed,
and download the descriptors listed in them.

- All hosts now attempt to download and keep fresh v3 authority
certificates, and re-attempt after failures.

happened inside connection_flushed_some(), do not call
connection_finished_flushing(). Should fix bug 451. Bugfix on
0.1.2.7-alpha.

2007-10-11 01:40:21 +02:00
o Major bugfixes (performance):
- Fix really bad O(n^2) performance when parsing a long list of
routers: Instead of searching the entire list for an "extra-info "
string which usually wasn't there, once for every routerinfo
we read, just scan lines forward until we find one we like.
Bugfix on 0.2.0.1.
r15689@catbus: nickm | 2007-10-11 16:40:25 -0400 Fix bug 451. This was a nasty bug, so let's fix it twice: first, by banning recursive calls to connection_handle_write from connection_flushed_some; and second, by not calling connection_finished_flushing() on a closed connection. Backport candidate. svn:r11882
2007-10-11 22:45:26 +02:00
- When we add data to a write buffer in response to the data on that

write buffer getting low because of a flush, do not consider the
newly added data as a candidate for immediate flushing, but rather
make it wait until the next round of writing. Otherwise, we flush
and refill recursively, and a single greedy TLS connection can
eat all of our bandwidth. Bugfix on 0.1.2.7-alpha.
r15420@catbus: nickm | 2007-09-27 15:40:25 -0400 Remove annotated_desc_store store (which we never used). Instead, shift name of router store to cached-descriptors, but initialize it from cached-routers as needed svn:r11678

certificate requests.

0.2.0.7-alpha.
rough up the changelog svn:r11856
2007-10-11 01:40:21 +02:00
- Only change the reply to a vote to "OK" if it's not already
set. This gets rid of annoying "400 OK" log messages, which may
have been masking some deeper issue. Bugfix on 0.2.0.7-alpha.
r15581@catbus: nickm | 2007-10-09 14:36:47 -0400 Recompute voting schedule whenever a consensus is set. svn:r11808

- When we get a valid consensus, recompute the voting schedule.

advantage of 64-bit platforms and to remove some possibly-costly
voodoo.

2007-10-09 17:27:15 +02:00
- Merge the extra fields in local_routerstatus_t back into
routerstatus_t: we used to need one routerstatus_t for each
authority's opinion, plus a local_routerstatus_t for the locally
rough up the changelog svn:r11856
2007-10-11 01:40:21 +02:00
computed consensus opinion. To save space, we put the locally
modified fields into local_routerstatus_t, and only the common
stuff into routerstatus_t. But once v3 directories are in use,
clients and caches will no longer need to hold authority opinions;
thus, the rationale for keeping the types separate is now gone.
- Make the code used to reschedule and reattempt downloads more
uniform.
- Turn all 'Are we a directory server/mirror?' logic into a call to
dirserver_mode().

2007-09-21 22:19:38 +02:00
o Major bugfixes (crashes):
- Fix possible segfaults in functions called from
rend_process_relay_cell(). Bugfix on 0.1.2.x.
o Major bugfixes (bridges):
- Fix a bug that made servers send a "404 Not found" in response to
attempts to fetch their server descriptor. This caused Tor servers
to take many minutes to establish reachability for their DirPort,
and it totally crippled bridges. Bugfix on 0.2.0.5-alpha.
Make "UpdateBridgesFromAuthority" torrc option work: when bridge users configure that and specify a bridge with an identity fingerprint, now they will lookup the bridge descriptor at the default bridge authority via a one-hop tunnel, but once circuits are established they will switch to a three-hop tunnel for later connections to the bridge authority. svn:r11550

connections to the bridge authority. Bugfix in 0.2.0.3-alpha.
o Major bugfixes (hidden services):
- Hidden services were choosing introduction points uniquely by
hexdigest, but when constructing the hidden service descriptor
they merely wrote the (potentially ambiguous) nickname.
- Clients now use the v2 intro format for hidden service
connections: they specify their chosen rendezvous point by identity
digest rather than by (potentially ambiguous) nickname. Both
are bugfixes on 0.1.2.x, and they could speed up hidden service
connections dramatically. Thanks to Karsten Loesing.

o Minor features (guard nodes):

2007-09-21 22:19:38 +02:00
- Tag every guard node in our state file with the version that
we believe added it, or with our own version if we add it. This way,
if a user temporarily runs an old version of Tor and then switches
back to a new one, she doesn't automatically lose her guards.

2007-10-22 10:52:01 +02:00
Tor 0.1.2.17 features a new Vidalia version in the Windows and OS
X bundles. Vidalia 0.0.14 makes authentication required for the
ControlPort in the default configuration, which addresses important
security risks. Everybody who uses Vidalia (or another controller)
should upgrade.
In addition, this Tor update fixes major load balancing problems with
path selection, which should speed things up a lot once many people
have upgraded.
forward-port the 0.1.2.17 changelog svn:r11340
2007-08-31 23:39:11 +02:00
o Major bugfixes (security):
- We removed support for the old (v0) control protocol. It has been
deprecated since Tor 0.1.1.1-alpha, and keeping it secure has
become more of a headache than it's worth.
o Major bugfixes (load balancing):
- When choosing nodes for non-guard positions, weight guards
proportionally less, since they already have enough load. Patch
from Mike Perry.
- Raise the "max believable bandwidth" from 1.5MB/s to 10MB/s. This
will allow fast Tor servers to get more attention.
- When we're upgrading from an old Tor version, forget our current
guards and pick new ones according to the new weightings. These
three load balancing patches could raise effective network capacity
by a factor of four. Thanks to Mike Perry for measurements.
o Major bugfixes (stream expiration):
- Expire not-yet-successful application streams in all cases if
they've been around longer than SocksTimeout. Right now there are
some cases where the stream will live forever, demanding a new
circuit every 15 seconds. Fixes bug 454; reported by lodger.
o Minor features (controller):
- Add a PROTOCOLINFO controller command. Like AUTHENTICATE, it
is valid before any authentication has been received. It tells
a controller what kind of authentication is expected, and what
protocol is spoken. Implements proposal 119.
o Minor bugfixes (performance):
- Save on most routerlist_assert_ok() calls in routerlist.c, thus
greatly speeding up loading cached-routers from disk on startup.
- Disable sentinel-based debugging for buffer code: we squashed all
the bugs that this was supposed to detect a long time ago, and now
its only effect is to change our buffer sizes from nice powers of
two (which platform mallocs tend to like) to values slightly over
powers of two (which make some platform mallocs sad).
o Minor bugfixes (misc):
- If exit bandwidth ever exceeds one third of total bandwidth, then
use the correct formula to weight exit nodes when choosing paths.
Based on patch from Mike Perry.
- Choose perfectly fairly among routers when choosing by bandwidth and
weighting by fraction of bandwidth provided by exits. Previously, we
would choose with only approximate fairness, and correct ourselves
if we ran off the end of the list.
- If we require CookieAuthentication but we fail to write the
cookie file, we would warn but not exit, and end up in a state
where no controller could authenticate. Now we exit.
- If we require CookieAuthentication, stop generating a new cookie
every time we change any piece of our config.
- Refuse to start with certain directory authority keys, and
encourage people using them to stop.
- Terminate multi-line control events properly. Original patch
from tup.
- Fix a minor memory leak when we fail to find enough suitable
servers to choose a circuit.
- Stop leaking part of the descriptor when we run into a particularly
unparseable piece of it.

the ControlPort in the default configuration, which addresses important
security risks.
In addition, this snapshot fixes major load balancing problems

mean-time-between-failure approach to tracking which servers are stable,
rather than just looking at the most recent uptime.

This fifth development snapshot fixes compilation on Windows again;
fixes an obnoxious client-side bug that slowed things down and put
extra load on the network; gets us closer to using the v3 directory
voting scheme; makes it easier for Tor controllers to use cookie-based
authentication; and fixes a variety of other bugs.
r14103@catbus: nickm | 2007-08-09 18:30:40 -0400 Drop v1 directory support: instead, just generate stub v1 directories. This should save lots and lots of directory bandwidth, and break any code relying on v1 directories, including Tor 0.1.0.x and earlier. svn:r11067
2007-08-10 00:32:33 +02:00
o Removed features:
clean up changelog in preparation for release svn:r11169
2007-08-19 04:01:02 +02:00
- Version 1 directories are no longer generated in full. Instead,
authorities generate and serve "stub" v1 directories that list
no servers. This will stop Tor versions 0.1.0.x and earlier from
working, but (for security reasons) nobody should be running those
versions anyway.

o Minor features (controller):
clean up changelog in preparation for release svn:r11169
2007-08-19 04:01:02 +02:00
- Add a PROTOCOLINFO controller command. Like AUTHENTICATE, it
is valid before any authentication has been received. It tells
a controller what kind of authentication is expected, and what
protocol is spoken. Implements proposal 119.
- New config option CookieAuthFile to choose a new location for the
cookie authentication file, and config option
CookieAuthFileGroupReadable to make it group-readable.

2007-08-19 04:01:02 +02:00
invoke any chosen test from the command line rather than having
to run the whole test suite at once; and so that we can turn on
logging for the unit tests.

2007-10-22 10:52:01 +02:00
Tor 0.1.2.16 fixes a critical security vulnerability that allows a
remote attacker in certain situations to rewrite the user's torrc
configuration file. This can completely compromise anonymity of users
in most configurations, including those running the Vidalia bundles,
TorK, etc. Or worse.
forward-port the 0.1.2.16 changelog svn:r11315
2007-08-30 10:40:52 +02:00
o Major security fixes:
- Close immediately after missing authentication on control port;
do not allow multiple authentication attempts.
r13892@Kushana: nickm | 2007-08-01 18:27:13 -0700 Close immediately after anything but a successful authentication attempt on the control port. Backport candidate. svn:r11016

2007-10-22 10:52:01 +02:00
This fourth development snapshot fixes a critical security vulnerability
for most users, specifically those running Vidalia, TorK, etc. Everybody
should upgrade to either 0.1.2.16 or 0.2.0.4-alpha.

r13872@Kushana: nickm | 2007-07-31 08:27:54 -0700 Rename IN4_ADDR and IN6_ADDR to try to avoid conflicting with Windows definitions. This may fix the windows build. svn:r11011
2007-08-01 17:57:34 +02:00
o Major bugfixes (compilation):
- Fix win32 compilation: apparently IN_ADDR and IN6_ADDR are already
defined there.
Yet another buffer RAM patch: tNever ever ever keep a buffer memory chunk around for an empty buffer that could go on the freelist. This wants profiling to make sure that performance doesnt suffer. svn:r10993
2007-07-30 19:47:43 +02:00
o Minor features (performance):
- Be even more aggressive about releasing RAM from small
empty buffers. Thanks to our free-list code, this shouldn't be too
performance-intensive.
r14024@catbus: nickm | 2007-07-30 14:13:58 -0400 Glibc (and maybe others) define a mallinfo() that can be used to see how the platform malloc is acting inside. When we have it, dump its output on dumpmemusage(). svn:r10996

o Major features:
clean up the changelog svn:r10986
2007-07-30 14:13:32 +02:00
- The first pieces of our "bridge" design for blocking-resistance
are implemented. People can run bridge directory authorities;
people can run bridges; and people can configure their Tor clients
with a set of bridges to use as the first hop into the Tor network.

2007-07-30 14:13:32 +02:00
User and Group. Now non-Windows users can choose port values
under 1024, start Tor as root, and have Tor bind those ports
before it changes to another UID. (Windows users could already
pick these ports.)
- Added a new ConstrainedSockets config option to set SO_SNDBUF and
SO_RCVBUF on TCP sockets. Hopefully useful for Tor servers running
on "vserver" accounts. (Patch from coderman.)
Be even more aggressive about separating local traffic from relayed traffic when RelayBandwidthRate is set. (Refines proposal 111.) svn:r10974

Of course, I have probably forgotten something, and there are probably bugs in there somewhere too. svn:r10976

o Major features (experimental):
clean up the changelog svn:r10986
2007-07-30 14:13:32 +02:00
- First cut of code for "v3 dir voting": directory authorities will
vote on a common network status document rather than each publishing
their own opinion. This code needs more testing and more corner-case
handling before it's ready for use.

2007-07-29 03:07:35 +02:00
o Security fixes:
- Directory authorities now call routers Fast if their bandwidth is
at least 100KB/s, and consider their bandwidth adequate to be a
Guard if it is at least 250KB/s, no matter the medians. This fix
complements proposal 107. [Bugfix on 0.1.2.x]

- Minor change to organizationName and commonName generation

some earlier censorware approaches. This is not a long-term
solution, but applying it will give us a bit of time to look into
the epidemiology of countermeasures as they spread.

o Performance improvements:

bugs. Everybody should upgrade.
forward-port the 0.1.2.15 changelog svn:r10859
2007-07-17 22:57:43 +02:00
o Major bugfixes (compilation):
- Fix compile on FreeBSD/NetBSD/OpenBSD. Oops.
o Major bugfixes (crashes):
- Try even harder not to dereference the first character after
an mmap(). Reported by lodger.
- Fix a crash bug in directory authorities when we re-number the
routerlist while inserting a new router.
- When the cached-routers file is an even multiple of the page size,
don't run off the end and crash. (Fixes bug 455; based on idea
from croup.)
- Fix eventdns.c behavior on Solaris: It is critical to include
orconfig.h _before_ sys/types.h, so that we can get the expected
definition of _FILE_OFFSET_BITS.
o Major bugfixes (security):
- Fix a possible buffer overrun when using BSD natd support. Bug
found by croup.
- When sending destroy cells from a circuit's origin, don't include
the reason for tearing down the circuit. The spec says we didn't,
and now we actually don't. Reported by lodger.
- Keep streamids from different exits on a circuit separate. This
bug may have allowed other routers on a given circuit to inject
cells into streams. Reported by lodger; fixes bug 446.
- If there's a never-before-connected-to guard node in our list,
never choose any guards past it. This way we don't expand our
guard list unless we need to.
o Minor bugfixes (guard nodes):
- Weight guard selection by bandwidth, so that low-bandwidth nodes
don't get overused as guards.
o Minor bugfixes (directory):
- Correctly count the number of authorities that recommend each
version. Previously, we were under-counting by 1.
- Fix a potential crash bug when we load many server descriptors at
once and some of them make others of them obsolete. Fixes bug 458.
o Minor bugfixes (hidden services):
- Stop tearing down the whole circuit when the user asks for a
connection to a port that the hidden service didn't configure.
Resolves bug 444.
o Minor bugfixes (misc):
- On Windows, we were preventing other processes from reading
cached-routers while Tor was running. Reported by janbar.
- Fix a possible (but very unlikely) bug in picking routers by
bandwidth. Add a log message to confirm that it is in fact
unlikely. Patch from lodger.
- Backport a couple of memory leak fixes.
- Backport miscellaneous cosmetic bugfixes.

This early development snapshot provides new features for people running
Tor as both a client and a server (check out the new RelayBandwidth
config options); lets Tor run as a DNS proxy; and generally moves us
forward on a lot of fronts.
polish 0.2.0.1-alpha changelog svn:r10436
2007-06-01 09:12:14 +02:00
o Major features, server usability:
- New config options RelayBandwidthRate and RelayBandwidthBurst:
a separate set of token buckets for relayed traffic. Right now
relayed traffic is defined as answers to directory requests, and
OR connections that don't have any local circuits on them.
o Major features, client usability:
- A client-side DNS proxy feature to replace the need for
dns-proxy-tor: Just set "DNSPort 9999", and Tor will now listen
for DNS requests on port 9999, use the Tor network to resolve them
anonymously, and send the reply back like a regular DNS server.
The code still only implements a subset of DNS.
- Make PreferTunneledDirConns and TunnelDirConns work even when
we have no cached directory info. This means Tor clients can now
do all of their connections protected by TLS.
o Major features, performance and efficiency:
- Directory authorities accept and serve "extra info" documents for
routers. These documents contain fields from router descriptors
that aren't usually needed, and that use a lot of excess
bandwidth. Once these fields are removed from router descriptors,
the bandwidth savings should be about 60%. [Partially implements
proposal 104.]
- Servers upload extra-info documents to any authority that accepts
them. Authorities (and caches that have been configured to download
extra-info documents) download them as needed. [Partially implements
proposal 104.]
r12651@Kushana: nickm | 2007-03-24 18:26:42 -0400 Initial version of circuit-based cell queues. Instead of hammering or_conns with piles of cells, queue cells on their corresponding circuits, and append them to the or_conn as needed. This seems to work so far, but needs a bit more work. This will break the memory-use-limitation patch for begin_dir conns: the solution will be a fun but fiddly. svn:r9904
2007-03-26 16:07:59 +02:00
- Change the way that Tor buffers data that it is waiting to write.
Instead of queueing data cells in an enormous ring buffer for each
client->OR or OR->OR connection, we now queue cells on a separate
queue for each circuit. This lets us use less slack memory, and
will eventually let us be smarter about prioritizing different kinds
of traffic.
if you're using relaybandwidthrate and relaybandwidthburst, make sure that's reflected in your router descriptor. svn:r10114
2007-05-04 11:20:13 +02:00
- Use memory pools to allocate cells with better speed and memory
efficiency, especially on platforms where malloc() is inefficient.
r12652@Kushana: nickm | 2007-03-25 15:01:48 -0400 A surprisingly simple patch to stop reading on edge connections when their circuits get too full, and start again when they empty out. This lets us remove the logic to block begin_dir conns when the corresponding or conns get full: it was already broken by cell queues anyway. svn:r9905
2007-03-26 16:08:18 +02:00

buffers are full; start again as the circuits empty out.

o Minor fixes (resource management):
polish up the 0.2.0.1-alpha in-progress changelog svn:r10174
2007-05-13 01:19:10 +02:00
- Count the number of open sockets separately from the number
of active connection_t objects. This will let us avoid underusing
our allocated connection limit.
r12763@Kushana: nickm | 2007-04-20 18:42:58 -0400 Initial version of code to stop using socket pairs for linked connections. Superficially, it seems to work, but it probably needs a lot more testing and attention. svn:r9995
2007-04-21 19:26:12 +02:00
- We no longer use socket pairs to link an edge connection to an

2007-05-13 01:19:10 +02:00
Instead, we track the link internally and transfer the data
in-process. This saves two sockets per "linked" connection (at the
client and at the server), and avoids the nasty Windows socketpair()
workaround.

o Minor features (build):
r12351@catbus: nickm | 2007-04-11 12:09:46 -0400 More autoconf hacking: use same machinery to find zlib as for openssl and libevent. Have unified library finder include setup for --with variable.

know if the compile succeeds anyway, so we can downgrade the
warning.
r12429@catbus: nickm | 2007-04-18 15:28:41 -0400 Make svn revision number visible in version even if building from a .tar.gz. This was remarkably painless. svn:r9988
2007-04-18 21:28:47 +02:00
- Include the current subversion revision as part of the version
string: either fetch it directly if we're in an SVN checkout, do
some magic to guess it if we're in an SVK checkout, or use
the last-detected version if we're building from a .tar.gz.

o Minor features (logging):
- Always prepend "Bug: " to any log message about a bug.
Put a platform string (e.g. "Linux i686") in the startup log message, so when people paste just their logs, we know if it's openbsd or windows or what. svn:r9775

2007-04-16 23:37:21 +02:00
o Minor features (directory system):
New config option V2AuthoritativeDirectory that all directory authorities should set. This will let future authorities choose not to serve V2 directory information. Also, go through and revamp all the authdir_mode stuff so it tries to do the right thing if you're an auth but not a V1 or V2 auth. svn:r10092

- More unit tests.
r12946@catbus: nickm | 2007-05-25 10:46:50 -0400 Add an AutomapHostsOnResolve option. It seems to work. svn:r10324
2007-05-25 16:48:16 +02:00
- Add a new AutomapHostsOnResolve option: when it is enabled, any
resolve request for hosts matching a given pattern causes Tor to
generate an internal virtual address mapping for that host. This
allows DNSPort to work sensibly with hidden service users. By
default, .exit and .onion addresses are remapped; the list of
patterns can be reconfigured with AutomapHostsSuffixes.
polish 0.2.0.1-alpha changelog svn:r10436
2007-06-01 09:12:14 +02:00
- Add an "-F" option to tor-resolve to force a resolve for a .onion
address. Thanks to the AutomapHostsOnResolve option, this is no
longer a completely silly thing to do.
If Tor is invoked from something that isn't a shell (e.g. Vidalia), now we expand "-f ~/.tor/torrc" correctly. Suggested by Matt Edman. svn:r10351

r12077@catbus: nickm | 2007-03-04 16:08:23 -0500 Remove support for v0 control protocol from 0.2.0.x trunk; send back error when we receive a v0 control message. (Leave "if(v1){...}"blocks indented for now so this patch is easier to read.) ((Finally, the linecount goes _down_ a little.)) svn:r9735
2007-03-04 22:08:28 +01:00
o Removed features:
- Removed support for the old binary "version 0" controller protocol.
This has been deprecated since 0.1.1, and warnings have been issued
polish 0.2.0.1-alpha changelog svn:r10436
2007-06-01 09:12:14 +02:00
since 0.1.2. When we encounter a v0 control message, we now send
back an error and close the connection.

2007-03-05 03:40:58 +01:00
- Remove the old "dns worker" server DNS code: it hasn't been default
since 0.1.2.2-alpha, and all the servers seem to be using the new
eventdns code.

o Minor bugfixes (directory):
- Correctly enforce that elements of directory objects do not appear
more often than they are allowed to appear.
- When we are reporting the DirServer line we just parsed, we were
logging the second stanza of the key fingerprint, not the first.

don't try to remove the log from the list: just mark it as
unusable. (Bulletproofs against bug 222.)

- In the exitlist script, only consider the most recently published
server descriptor for each server. Also, when the user requests
a list of servers that _reject_ connections to a given address,

Instead of hammering or_conns with piles of cells, queue cells on their corresponding circuits, and append them to the or_conn as needed. This seems to work so far, but needs a bit more work.

2007-10-22 10:52:01 +02:00
Tor 0.1.2.14 changes the addresses of two directory authorities (this
change especially affects those who serve or use hidden services),
and fixes several other crash- and security-related bugs.
forward-port the 0.1.2.14 changelog, and remove redundant entries from the 0.2.0.1 changelog svn:r10338
2007-05-25 23:31:49 +02:00
o Directory authority changes:
- Two directory authorities (moria1 and moria2) just moved to new
IP addresses. This change will particularly affect those who serve
or use hidden services.
o Major bugfixes (crashes):
- If a directory server runs out of space in the connection table
as it's processing a begin_dir request, it will free the exit stream
but leave it attached to the circuit, leading to unpredictable
behavior. (Reported by seeess, fixes bug 425.)
- Fix a bug in dirserv_remove_invalid() that would cause authorities
to corrupt memory under some really unlikely scenarios.
- Tighten router parsing rules. (Bugs reported by Benedikt Boss.)
- Avoid segfaults when reading from mmaped descriptor file. (Reported
by lodger.)
o Major bugfixes (security):
- When choosing an entry guard for a circuit, avoid using guards
that are in the same family as the chosen exit -- not just guards
that are exactly the chosen exit. (Reported by lodger.)
o Major bugfixes (resource management):
- If a directory authority is down, skip it when deciding where to get
networkstatus objects or descriptors. Otherwise we keep asking
every 10 seconds forever. Fixes bug 384.
- Count it as a failure if we fetch a valid network-status but we
don't want to keep it. Otherwise we'll keep fetching it and keep
not wanting to keep it. Fixes part of bug 422.
- If all of our dirservers have given us bad or no networkstatuses
lately, then stop hammering them once per minute even when we
think they're failed. Fixes another part of bug 422.
o Minor bugfixes:
- Actually set the purpose correctly for descriptors inserted with
purpose=controller.
- When we have k non-v2 authorities in our DirServer config,
we ignored the last k authorities in the list when updating our
network-statuses.
- Correctly back-off from requesting router descriptors that we are
having a hard time downloading.
- Read resolv.conf files correctly on platforms where read() returns
partial results on small file reads.
- Don't rebuild the entire router store every time we get 32K of
routers: rebuild it when the journal gets very large, or when
the gaps in the store get very large.
o Minor features:
- When routers publish SVN revisions in their router descriptors,
authorities now include those versions correctly in networkstatus
documents.
- Warn when using a version of libevent before 1.3b to run a server on
OSX or BSD: these versions interact badly with userspace threads.

2007-10-22 10:52:01 +02:00
This release features some major anonymity fixes, such as safer path
selection; better client performance; faster bootstrapping, better
address detection, and better DNS support for servers; write limiting as
well as read limiting to make servers easier to run; and a huge pile of
other features and bug fixes. The bundles also ship with Vidalia 0.0.11.
and synchronize that with the ReleaseNotes file svn:r12094
2007-10-22 10:54:32 +02:00
Tor 0.1.2.13 is released in memory of Rob Levin (1955-2006), aka lilo
of the Freenode IRC network, remembering his patience and vision for
free speech on the Internet.

2007-04-24 20:29:57 +02:00
o Minor fixes:
- Fix a memory leak when we ask for "all" networkstatuses and we
get one we don't recognize.
- Add more asserts to hunt down bug 417.
- Disable kqueue on OS X 10.3 and earlier, to fix bug 371.
forward-port r9850 and the changelogs (it's a band) svn:r9853
2007-03-17 05:32:04 +01:00
Changes in version 0.1.2.12-rc - 2007-03-16
o Major bugfixes:
- Fix an infinite loop introduced in 0.1.2.7-alpha when we serve
directory information requested inside Tor connections (i.e. via
begin_dir cells). It only triggered when the same connection was
serving other data at the same time. Reported by seeess.
o Minor bugfixes:
- When creating a circuit via the controller, send a 'launched'
event when we're done, so we follow the spec better.
Changes in version 0.1.2.11-rc - 2007-03-15
o Minor bugfixes (controller), reported by daejees:
- Correct the control spec to match how the code actually responds
to 'getinfo addr-mappings/*'.
- The control spec described a GUARDS event, but the code
implemented a GUARD event. Standardize on GUARD, but let people
ask for GUARDS too.

a clearer changelog, and a future todo item svn:r9702
2007-03-01 06:04:54 +01:00
o Major bugfixes (Windows):
- On MinGW, use "%I64u" to printf/scanf 64-bit integers, instead
of the usual GCC "%llu". This prevents a bug when saving 64-bit
int configuration values: the high-order 32 bits would get
truncated. In particular, we were being bitten by the default
MaxAdvertisedBandwidth of 128 TB turning into 0. (Fixes bug 400
and maybe also bug 397.)
r11959@catbus: nickm | 2007-02-26 22:53:36 -0500 try to make aes encryption of cells about 30-40% faster where applicable. offer not available for all architectures or all versions of openssl. svn:r9663
2007-02-27 04:53:45 +01:00
o Minor bugfixes (performance):
- Use OpenSSL's AES implementation on platforms where it's faster.
This could save us as much as 10% CPU usage.
r11958@catbus: nickm | 2007-02-26 22:28:03 -0500 Add a missing set to onion_key_set_at to avoid premature rotates. svn:r9662
2007-02-27 04:53:40 +01:00
o Minor bugfixes (server):
- Do not rotate onion key immediately after setting it for the first
time.

o Minor bugfixes (directory authorities):
- Stop calling servers that have been hibernating for a long time "stable". Also, stop letting hibernating or obsolete servers affect uptime and bandwidth cutoffs. - Stop listing hibernating servers in the v1 directory. svn:r9690

r12012@catbus: nickm | 2007-02-28 18:25:18 -0500 Twiddle constants wrt uploading hidden service descriptors. svn:r9694
2007-03-01 01:41:28 +01:00
o Minor bugfixes (hidden services):
- Upload hidden service descriptors slightly less often, to reduce
load on authorities.
r11970@catbus: nickm | 2007-02-27 19:17:27 -0500 Fix a bug found by Udo van den Heuvel: avoid an assertion failure when a controller sets and clears EntryNodes before the next call to choose_random_entry(). Also make a function static. svn:r9669
2007-02-28 01:23:05 +01:00
o Minor bugfixes (other):
- Fix an assert that could trigger if a controller quickly set then
cleared EntryNodes. (Bug found by Udo van den Heuvel.)
r11981@catbus: nickm | 2007-02-28 11:55:27 -0500 Clamp declarable bandwidth at INT32_MAX, not INT_MAX. svn:r9677
2007-02-28 17:56:07 +01:00
- On architectures where sizeof(int)>4, still clamp declarable bandwidth
to INT32_MAX.
Update changelog with rpm race fix. svn:r9680
2007-02-28 18:27:36 +01:00
- Fix a potential race condition in the rpm installer. Found by
Stefan Nordhausen.
r12000@catbus: nickm | 2007-02-28 15:12:21 -0500 Try to fix eventdns bug 326 again, this time by noting that rcode 2 (serverfailed) does not really mean "The server is useless." svn:r9687
2007-02-28 21:24:23 +01:00
- Try to fix eventdns warnings once and for all: do not treat a dns rcode
of 2 as indicating that the server is completely bad; it sometimes
means that the server is just bad for the request in question. (may fix
the last of bug 326.)
Disable encrypted directory connections when we don't have a server descriptor for the destination. We'll get this working again in the 0.2.0 branch. svn:r9700

3 of bug 367.)

2007-02-09 01:21:41 +01:00
- Display correct results when reporting which versions are
recommended, and how recommended they are. (Resolves bug 383.)
- Improve our estimates for directory bandwidth to be less random:
guess that an unrecognized directory will have the average bandwidth
from all known directories, not that it will have the average
bandwidth from those directories earlier than it on the list.

r11774@catbus: nickm | 2007-02-12 16:31:47 -0500 Handle errors on opening cached-routers* more uniformly and sanely: log not-found errors at level INFO, and all other errors at level WARN. Needs testing on win32. svn:r9569
2007-02-12 22:39:44 +01:00
- On platforms with no working mmap() equivalent, don't warn the
user when cached-routers doesn't exist.
- Warn the user when mmap() [or its equivalent] fails for some reason
other than file-not-found.

Also, when entrynodes is configured, then build the guard list as: (parts of EntryNodes that were guards before), (the rest of EntryNodes), (the rest of the old guards). This last point ensures that EntryNode users will get the EntryNodes they want with the minimum change to their guard list. svn:r9574

- Mask out all signals in sub-threads; only the libevent signal
handler should be processing them. This should prevent some crashes
on some machines using pthreads. (Patch from coderman.)
- Fix switched arguments on memset in the implementation of
tor_munmap() for systems with no mmap() call.
- When Tor receives a router descriptor that it asked for, but
no longer wants (because it has received fresh networkstatuses
in the meantime), do not warn the user. Cache the descriptor if
we're a cache; drop it if we aren't.
- Make earlier entry guards _really_ get retried when the network

r11726@catbus: nickm | 2007-02-08 16:04:53 -0500 Resolve some XXXX012 items: - Remove PathlenCoinWeight: if we want it again, we can add it back in. - Ditto with RelayBandwidth*. - Decide to leave in the "hey, you didn't set end_reason!" BUG log message, but stop telling people to bug me personally. - Postpone strengthening assert_connection_ok(): it's important, but it's also a good way to introduce weird bugs. - Move some expensive consistency checking from dns_free_all() into assert_cache_ok(). svn:r9533
2007-02-08 23:07:56 +01:00
- Remove some never-implemented options. Mark PathlenCoinWeight as
obsolete.
r11773@catbus: nickm | 2007-02-12 15:18:48 -0500 Implement proposal 106: stop requiring clients to have certificates, and stop checking for nicknames in certificates. [See proposal 106 for rationale.] Also improve messages when checking TLS handshake, to re-resolve bug 382. svn:r9568
2007-02-12 22:39:33 +01:00
- Implement proposal 106: Stop requiring clients to have well-formed
more cleanup svn:r9650
2007-02-25 14:39:33 +01:00
certificates; stop checking nicknames in certificates. (Clients
have certificates so that they can look like Tor servers, but in
the future we might want to allow them to look like regular TLS
clients instead. Nicknames in certificates serve no purpose other
than making our protocol easier to recognize on the wire.)

2007-02-12 22:39:33 +01:00
- Revise messages on handshake failure again to be even more clear about
which are incoming connections and which are outgoing.
r11781@catbus: nickm | 2007-02-12 18:31:33 -0500 Discard any v1 directory info that is so old as to be useless. (Fixes bug 387) svn:r9572
2007-02-13 00:39:24 +01:00
- Discard any v1 directory info that's over 1 month old (for
directories) or over 1 week old (for running-routers lists).
r11785@catbus: nickm | 2007-02-12 20:27:48 -0500 Node-picking fixes: Never warn when a down node is listed in a config option (bug 348); always warn when a node in a config option is unnamed. Also, when entrynodes is configured, then build the guard list as: (parts of EntryNodes that were guards before), (the rest of EntryNodes), (the rest of the old guards). This last point ensures that EntryNode users will get the EntryNodes they want with the minimum change to their guard list. svn:r9574
2007-02-13 02:27:55 +01:00
- Do not warn when individual nodes in the configuration's EntryNodes,
more cleanup svn:r9650
2007-02-25 14:39:33 +01:00
ExitNodes, etc are down: warn only when all possible nodes
are down. (Fixes bug 348.)
r11787@catbus: nickm | 2007-02-12 21:01:34 -0500 Always remove expired routers and networkstatus docs before checking whether we have enough information to build circuits. (Fixes bug 373.) svn:r9575

o Major bugfixes (rate limiting):
add a changelog item, rearrange some others svn:r9367
2007-01-18 04:35:13 +01:00
- Servers decline directory requests much more aggressively when
they're low on bandwidth. Otherwise they end up queueing more and
more directory responses, which can't be good for latency.
a bit of revisionist history for our changelog svn:r9520
2007-02-08 06:38:17 +01:00
- But never refuse directory requests from local addresses.
more changes. i'm all caught up now. svn:r9495
2007-02-06 03:49:07 +01:00
- Fix a memory leak when sending a 503 response for a networkstatus
request.
Be willing to read or write on local connections (e.g. controller connections) even when the global rate limiting buckets are empty. svn:r9368
2007-01-18 04:38:24 +01:00
- Be willing to read or write on local connections (e.g. controller
connections) even when the global rate limiting buckets are empty.
If our system clock jumps back in time, don't publish a negative uptime in the descriptor. Also, don't let the global rate limiting buckets go absurdly negative. svn:r9377

reformat the 0.1.2.7-alpha changelog a bit svn:r9420
2007-01-26 08:54:16 +01:00
- Flush local controller connection buffers periodically as we're
writing to them, so we avoid queueing 4+ megabytes of data before
trying to flush.
r11643@catbus: nickm | 2007-02-05 15:44:59 -0500 Fix bug 254, sort of: make the default NT service user NetworkService rather than NULL (system). Also, add a --user argument to --service install so that admins can override this default: this latter point should take care of most of my objections to NetworkService. I have no idea whether this even compiles. svn:r9486
2007-02-05 21:45:02 +01:00
o Major bugfixes (NT services):
r11646@catbus: nickm | 2007-02-05 16:15:48 -0500 Make default NT service user be LocalService. Again, I have no idea if this compiles, let alone if it works. svn:r9487

command-line flag so that admins can override the default by saying
r11676@catbus: nickm | 2007-02-07 00:10:00 -0500 (Hopefully) final changes for 0.1.2.7-alpha: disable checking for whether the user account in question exists on --service install, since that seems to make windows go boom. We can figure out why later. Also, let the admin specify a password for the target user. svn:r9506

r11667@catbus: nickm | 2007-02-06 13:36:18 -0500 The --service install code can no longer default to adding an -f option for the appdata directory of the current user, since the target user probably will not be able to read it. Instead, warn the user if no explicit torrc filename is given. svn:r9502
2007-02-06 19:36:26 +01:00
existing installed services. Also, warn the user that the service
will look for its configuration file in the service user's
%appdata% directory. (We can't do the 'hardwire the user's appdata
directory' trick any more, since we may not have read access to that
directory.)

o Major bugfixes (other):
- Previously, we would cache up to 16 old networkstatus documents
indefinitely, if they came from nontrusted authorities. Now we
discard them if they are more than 10 days old.
more changes. i'm all caught up now. svn:r9495
2007-02-06 03:49:07 +01:00
- Fix a crash bug in the presence of DNS hijacking (reported by Andrew
Del Vecchio).
r9692@catbus: nickm | 2007-01-21 12:04:22 -0500 Detect pointer loops in DNS requests and replies; avoid infinite loop on such malformed replies. Fixes bug 380. svn:r9378
2007-01-21 18:05:10 +01:00
- Detect and reject malformed DNS responses containing circular
pointer loops.
cleanups based on looking through svn commits svn:r9491
2007-02-06 01:27:03 +01:00
- If exits are rare enough that we're not marking exits as guards,
ignore exit bandwidth when we're deciding the required bandwidth
to become a guard.
- When we're handling a directory connection tunneled over Tor,
don't fill up internal memory buffers with all the data we want
to tunnel; instead, only add it if the OR connection that will
eventually receive it has some room for it. (This can lead to
slowdowns in tunneled dir connections; a better solution will have
to wait for 0.2.0.)
r11931@Kushana: nickm | 2007-01-11 09:12:49 -0500 Fix a crash bug in the presence of DNS hijacking. svn:r9333

2007-01-10 20:49:21 +01:00
- Add some defensive programming to eventdns.c in an attempt to catch
possible memory-stomping bugs.

extra bytes.)
- Fix as-yet-unused reverse IPv6 lookup code so it sends nybbles

- Free memory held in recently-completed DNS lookup attempts on exit.
This was not a memory leak, but may have been hiding memory leaks.
more changes. i'm all caught up now. svn:r9495
2007-02-06 03:49:07 +01:00
- Handle TTL values correctly on reverse DNS lookups.
- Treat failure to parse resolv.conf as an error.
o Minor bugfixes (other):
- Fix crash with "tor --list-fingerprint" (reported by seeess).
- When computing clock skew from directory HTTP headers, consider what
time it was when we finished asking for the directory, not what
time it is now.
- Expire socks connections if they spend too long waiting for the
handshake to finish. Previously we would let them sit around for
days, if the connecting application didn't close them either.
- And if the socks handshake hasn't started, don't send a
"DNS resolve socks failed" handshake reply; just close it.
- Stop using C functions that OpenBSD's linker doesn't like.
r9723@catbus: nickm | 2007-01-22 15:47:17 -0500 Fix an XXXX012 in routerlist.c: when we do not have enough networkstatuses to launch router requests, do not launch router requests. Backport candidate. svn:r9388
2007-01-22 21:57:26 +01:00
- Don't launch requests for descriptors unless we have networkstatuses
reformat the 0.1.2.7-alpha changelog a bit svn:r9420
2007-01-26 08:54:16 +01:00
from at least half of the authorities. This delays the first
download slightly under pathological circumstances, but can prevent
us from downloading a bunch of descriptors we don't need.
- Do not log IPs with TLS failures for incoming TLS
connections. (Fixes bug 382.)

r11592@catbus: nickm | 2007-01-29 18:09:16 -0500 Oops. Apparently, we weren't supposed to call our autoconf cached variables ac_cv_*; these are reserved. svn:r9460
2007-01-30 00:09:26 +01:00
- Stop using the reserved ac_cv namespace in our configure script.
r11620@catbus: nickm | 2007-02-01 13:06:27 -0500 Call stat() slightly less often; use fstat() when possible. svn:r9472
2007-02-01 19:09:27 +01:00
- Call stat() slightly less often; use fstat() when possible.
r11637@catbus: nickm | 2007-02-05 12:41:51 -0500 Fix an XXXX012, and make circuits_pending_or_conns a static variable. In addition to cleaning up the code, this may also resolve Bug 386 if Roger has the right intuition there. svn:r9482
2007-02-05 18:42:40 +01:00
- Refactor the way we handle pending circuits when an OR connection
completes or fails, in an attempt to fix a rare crash bug.
Only rewrite a conn's address based on X-Forwarded-For: headers if it's a parseable public IP address; and stop adding extra quotes to the resulting address. svn:r9505

as at the client, and warn less verbosely when they fail. You can
override this by setting ServerDNSAllowNonRFC953Addresses to 1.
minor cleanups svn:r9387
2007-01-22 20:20:33 +01:00
- Adapt a patch from goodell to let the contrib/exitlist script

r11586@catbus: nickm | 2007-01-29 13:13:27 -0500 Add a couple of fixes I turned up while writing regression tests for libevent: Allow DNS servers on ports other than 53, and handle TTLs correctly on reverse hostname lookups. svn:r9458
2007-01-29 19:13:42 +01:00
- Allow exit nodes to use nameservers running on ports other than 53.

2007-02-06 19:36:21 +01:00
- Add an --ignore-missing-torrc command-line option so that we can
get the "use sensible defaults if the configuration file doesn't
exist" behavior even when specifying a torrc location on the command
line.

o Minor bugfixes:
- Warn if we (as a server) find that we've resolved an address that we
weren't planning to resolve.
- Warn that using select() on any libevent version before 1.1 will be
unnecessarily slow (even for select()).
- Flush ERR-level controller status events just like we currently
flush ERR-level log events, so that a Tor shutdown doesn't prevent
the controller from learning about current events.
o Minor features (more controller status events):

2007-01-06 06:42:31 +01:00
- Implement EXTERNAL_ADDRESS server status event so controllers can
learn when our address changes.
- Implement BAD_SERVER_DESCRIPTOR server status event so controllers
can learn when directories reject our descriptor.
- Implement SOCKS_UNKNOWN_PROTOCOL client status event so controllers
can learn when a client application is speaking a non-socks protocol
to our SocksPort.
- Implement DANGEROUS_SOCKS client status event so controllers
can learn when a client application is leaking DNS addresses.
- Implement BUG general status event so controllers can learn when
Tor is unhappy about its internal invariants.
- Implement CLOCK_SKEW general status event so controllers can learn
when Tor thinks the system clock is set incorrectly.
- Implement GOOD_SERVER_DESCRIPTOR and ACCEPTED_SERVER_DESCRIPTOR
server status events so controllers can learn when their descriptors
are accepted by a directory.
- Implement CHECKING_REACHABILITY and REACHABILITY_{SUCCEEDED|FAILED}

some cleanups. more probably remain, but hey, it's an alpha. time to put out the bugfix release. svn:r9309
2007-01-09 06:14:34 +01:00
- Authorities no longer recommend exits as guards if this would shift
too much load to the exit nodes.
r11862@Kushana: nickm | 2007-01-06 01:05:15 -0500 Re-enable warning when we resolve an already resolved address. We only warn here now if the address is not a testing address. Also, refactor out a function to check whether an address is used for testing. svn:r9280

Changes in version 0.1.2.5-alpha - 2007-01-06
finish enabling begin-dir cells. require one-hop circs for socks-command-connect-dir streams, so we don't open new anonymity questions. svn:r9099
2006-12-13 03:49:45 +01:00
o Major features:
a changelog for write limiting. also, disable the "advertise dirport until we reach our max bandwidth if it's tiny" trick now that we do the bandwidth self-test on boot. svn:r9134
2006-12-15 22:39:35 +01:00
- Enable write limiting as well as read limiting. Now we sacrifice
capacity if we're pushing out lots of directory traffic, rather
than overrunning the user's intended bandwidth limits.
r11741@Kushana: nickm | 2006-12-28 22:41:29 -0500 Count TLS bytes accurately: previously, we counted only the number of bytes read or transmitted via tls, not the number of extra bytes used to do so. This has been a lonstanding wart. The fix "Works for me". svn:r9207
2006-12-29 04:42:46 +01:00
- Include TLS overhead when counting bandwidth usage; previously, we

would count only the bytes sent over TLS, but not the bytes used
to send them.
i like this 0.1.2.5-alpha changelog better svn:r9275
2007-01-06 06:14:57 +01:00
- Support running the Tor service with a torrc not in the same
directory as tor.exe and default to using the torrc located in
the %appdata%\Tor\ of the user who installed the service. Patch
from Matt Edman.
- Servers now check for the case when common DNS requests are going to
wildcarded addresses (i.e. all getting the same answer), and change
their exit policy to reject *:* if it's happening.
- Implement BEGIN_DIR cells, so we can connect to the directory
server via TLS to do encrypted directory requests rather than
plaintext. Enable via the TunnelDirConns and PreferTunneledDirConns
config options if you like.

disk writes as possible while still storing important things in
a timely fashion.

- Make PIDFile work on Windows (untested).
r11598@Kushana: nickm | 2006-12-15 15:59:00 -0500 Add internal documentation for a bunch of configuration options. We should do something to keep this list, the canonical list, the tor.1 list, and the torrc.complete list in sync. svn:r9133
2006-12-15 22:27:19 +01:00

avoid some inadvertent info leaks. Add an option
AllowNonRFC953Hostnames to disable this behavior, in case somebody
is running a private network with hosts called @, !, and #.
r11651@Kushana: nickm | 2006-12-20 12:05:04 -0500 Add a maintainer script and a new make target "make check-docs" to get a quick dump of which options are undocumented where, and which documentation refers to nonexistent options. svn:r9160
2006-12-20 18:05:48 +01:00

2007-01-06 06:14:57 +01:00
- Add a new address-spec.txt document to describe our special-case
addresses: .exit, .onion, and .noconnnect.
o Minor features (DNS):
- Ongoing work on eventdns infrastructure: now it has dns server
and ipv6 support. One day Tor will make use of it.
- Add client-side caching for reverse DNS lookups.
- Add support to tor-resolve tool for reverse lookups and SOCKS5.
- When we change nameservers or IP addresses, reset and re-launch
our tests for DNS hijacking.
o Minor features (directory):
- Authorities now specify server versions in networkstatus. This adds
forward-port the 0.1.2.13 changelog and releasenotes svn:r10018
2007-04-24 20:29:57 +02:00
about 2% to the size of compressed networkstatus docs, and allows

The implementation is forward-compatible with a proposed future
protocol version scheme not tied to Tor versions.

- Directory servers are more willing to send a 503 "busy" if they
are near their write limit, especially for v1 directory requests.
Now they can use their limited bandwidth for actual Tor traffic.

o Minor features (controller):
- Have GETINFO dir/status/* work on hosts with DirPort disabled.
- Reimplement GETINFO so that info/names stays in sync with the
actual keys.
- Implement "GETINFO fingerprint".
- Implement "SETEVENTS GUARD" so controllers can get updates on
entry guard status as it changes.
o Minor features (clean up obsolete pieces):
- Remove some options that have been deprecated since at least
0.1.0.x: AccountingMaxKB, LogFile, DebugLogFile, LogLevel, and
SysLog. Use AccountingMax instead of AccountingMaxKB, and use Log
to set log options.
- We no longer look for identity and onion keys in "identity.key" and
"onion.key" -- these were replaced by secret_id_key and
secret_onion_key in 0.0.8pre1.
- We no longer require unrecognized directory entries to be
preceded by "opt".
o Major bugfixes (security):
forward-port the 0.1.1.26 changelog, plus some other entries svn:r9128
2006-12-15 20:56:56 +01:00
- Stop sending the HttpProxyAuthenticator string to directory
servers when directory connections are tunnelled through Tor.
- Clients no longer store bandwidth history in the state file.
- Do not log introduction points for hidden services if SafeLogging
is set.
- When generating bandwidth history, round down to the nearest
1k. When storing accounting data, round up to the nearest 1k.
- When we're running as a server, remember when we last rotated onion
keys, so that we will rotate keys once they're a week old even if
we never stay up for a week ourselves.

r11486@Kushana: nickm | 2006-12-08 00:58:47 -0500 Fix a longstanding bug in eventdns related to timeouts: The timeout count was never actually reset to 0. Argh.

2007-01-26 07:44:38 +01:00
Changes in version 0.1.1.26 - 2006-12-14
o Security bugfixes:
- Stop sending the HttpProxyAuthenticator string to directory
servers when directory connections are tunnelled through Tor.
- Clients no longer store bandwidth history in the state file.
- Do not log introduction points for hidden services if SafeLogging
is set.
o Minor bugfixes:
- Fix an assert failure when a directory authority sets
AuthDirRejectUnlisted and then receives a descriptor from an
unlisted router (reported by seeess).

2006-12-03 17:48:01 +01:00
Changes in version 0.1.2.4-alpha - 2006-12-03
cleanups, bump to 0.1.2.4-alpha svn:r9015
2006-12-02 23:47:46 +01:00
o Major features:
- Add support for using natd; this allows FreeBSDs earlier than
5.1.2 to have ipfw send connections through Tor without using
SOCKS. (Patch from Zajcev Evgeny with tweaks from tup.)
r9308@totoro: nickm | 2006-11-13 18:41:23 -0500 Add support for (Free?)BSD's natd, which was an old way to let you have your firewall automatically redirect traffic. (Original patch from Zajcev Evgeny, updated for 0.1.2.x by tup.) svn:r8946
2006-11-14 01:06:31 +01:00
cleanups, bump to 0.1.2.4-alpha svn:r9015
2006-12-02 23:47:46 +01:00
o Minor features:
- Make all connections to addresses of the form ".noconnect"
immediately get closed. This lets application/controller combos
successfully test whether they're talking to the same Tor by
watching for STREAM events.
- Make cross.sh cross-compilation script work even when autogen.sh
hasn't been run. (Patch from Michael Mohr.)
- Statistics dumped by -USR2 now include a breakdown of public key
operations, for profiling.
r9561@Kushana: nickm | 2006-11-16 22:32:54 -0500 Tweaks to test-connection patch: use ".noconnect" instead of ".test" (since there are lots of ways to test things). Use a regular sequence of STREAM events (NEW followed by CLOSED) instead of a new event type. Make the function that checks the address be static and use const and strcasecmpend properly. svn:r8959

cleanups, bump to 0.1.2.4-alpha svn:r9015
2006-12-02 23:47:46 +01:00
o Major bugfixes:
- Fix a major leak when directory authorities parse their
approved-routers list, a minor memory leak when we fail to pick
an exit node, and a few rare leaks on errors.
r9307@totoro: nickm | 2006-11-13 18:25:56 -0500 Patch from tup based on patch from Zajcev Evgeny: Make TransPort work even when the server wants to talk before the client. svn:r8945

2006-11-01 00:35:50 +01:00
- Don't log spurious warnings when we see a circuit close reason we
don't recognize; it's probably just from a newer version of Tor.

2007-01-26 07:44:38 +01:00
Changes in version 0.1.1.25 - 2006-11-04
o Major bugfixes:
- When a client asks us to resolve (rather than connect to)
an address, and we have a cached answer, give them the cached
answer. Previously, we would give them no answer at all.
- We were building exactly the wrong circuits when we predict
hidden service requirements, meaning Tor would have to build all
its circuits on demand.
- If none of our live entry guards have a high uptime, but we
require a guard with a high uptime, try adding a new guard before
we give up on the requirement. This patch should make long-lived
connections more stable on average.
- When testing reachability of our DirPort, don't launch new
tests when there's already one in progress -- unreachable
servers were stacking up dozens of testing streams.
o Security bugfixes:
- When the user sends a NEWNYM signal, clear the client-side DNS
cache too. Otherwise we continue to act on previous information.
o Minor bugfixes:
- Avoid a memory corruption bug when creating a hash table for
the first time.
- Avoid possibility of controller-triggered crash when misusing
certain commands from a v0 controller on platforms that do not
handle printf("%s",NULL) gracefully.
- Avoid infinite loop on unexpected controller input.
- Don't log spurious warnings when we see a circuit close reason we
don't recognize; it's probably just from a newer version of Tor.
- Add Vidalia to the OS X uninstaller script, so when we uninstall
Tor/Privoxy we also uninstall Vidalia.

clean changelog, bump to 0.1.2.3-alpha svn:r8860
2006-10-30 03:55:17 +01:00
- If most authorities set a BadExit flag for a server, clients
don't think of it as a general-purpose exit. Clients only consider
authorities that advertise themselves as listing bad exits.
r9277@Kushana: nickm | 2006-10-19 19:03:05 -0400 Add pragma:no-cache and expires headers so that directory lookups can work better in the presence of caching HTTP proxies. (I would have used Cache-Control, but that is an HTTP/1.1 thing.) All timeouts are currently wild-assed guesses. svn:r8765
2006-10-20 01:05:34 +02:00
- Directory servers now provide 'Pragma: no-cache' and 'Expires'
headers for content, so that we can work better in the presence of
caching HTTP proxies.
r9318@Kushana: nickm | 2006-10-22 15:22:57 -0400 Let directory authorities set the BadExit flag if they like. Also, refactor directory authority code so we can believe multiple things about a single router, and do fewer linear searches. svn:r8794
2006-10-23 05:48:42 +02:00
- Allow authorities to list nodes as bad exits by fingerprint or by
address.

a router's status has changed.
r9364@Kushana: nickm | 2006-10-23 22:57:48 -0400 Remove reference to NS_FULL event; add two GETINFO targets. svn:r8812

2006-10-30 03:55:17 +01:00
- Avoid sending junk to controllers or segfaulting when a controller
uses EVENT_NEW_DESC with verbose nicknames.
- Stop triggering asserts if the controller tries to extend hidden
service circuits (reported by mwenge).
- Avoid infinite loop on unexpected controller input.
- When the controller does a "GETINFO network-status", tell it
about even those routers whose descriptors are very old, and use
long nicknames where appropriate.

In the hidden service example in torrc.sample, stop recommending esoteric and discouraged hidden service options. svn:r8648
2006-10-08 09:45:16 +02:00
- Do DirPort reachability tests less often, since a single test
chews through many circuits before giving up.
- In the hidden service example in torrc.sample, stop recommending
esoteric and discouraged hidden service options.
r8970@totoro: nickm | 2006-10-09 10:12:53 -0400 Win32 patch from Matt Edman: fix compilation bugs by casting to int; defining SSIZE_T; defining USE_TWOS_COMPLEMENT in windows orconfig.h; and using the proper names for win32 functions on GetProcAddress. Also fixes bug 295. svn:r8669
2006-10-09 17:46:21 +02:00
- When stopping an NT service, wait up to 10 sec for it to actually
stop. (Patch from Matt Edman; resolves bug 295.)
r8983@totoro: nickm | 2006-10-09 14:19:18 -0400 Add missing ! to code to generate short/verbose nicknames for orconn events. svn:r8674
2006-10-09 20:19:32 +02:00
- Fix handling of verbose nicknames with ORCONN controller events:
make them show up exactly when requested, rather than exactly when
not requested.
When reporting verbose nicknames in entry_guards_getinfo(), avoid printing a duplicate "$" in the keys we send. (Reported by mwenge) svn:r8681

- Correctly set maximum connection limit on Cygwin. (This time
for sure!)
- Try to detect Windows correctly when cross-compiling.
- Detect the size of the routers file correctly even if it is
corrupted (on systems without mmap) or not page-aligned (on systems
with mmap). This bug was harmless.
- Sometimes we didn't bother sending a RELAY_END cell when an attempt
to open a stream fails; now we do in more cases. This should
make clients able to find a good exit faster in some cases, since
unhandleable requests will now get an error rather than timing out.
and a changelog entry to go with it svn:r8790

Previously, clients could only connect to director servers over Tor from exit nodes, but couldn't get directory information anonymously from a non-exit cache without getting a directory server involved. This needs testing, and needs client-side code to actually exercise it. svn:r8527

NEEDS REVIEW. Act on previous comment, and handle named servers differently: now, we allow multiple servers with the same name in the routerlist even if that name is reserved, but we check whether names are reserved when we try to look up routers by nickname. This is a minor security fix. This makes router_add_to_routerlist O(1). This is a backport candidate. svn:r8433

o Minor bugfixes, performance:
- Two small performance improvements on parsing descriptors.
- Major performance improvement on inserting descriptors: change
algorithm from O(n^2) to O(n).
- Make the common memory allocation path faster on machines where

- Avoid duplicate entries on MyFamily line in server descriptor.
o Packaging, features:
- Remove architecture from OS X builds. The official builds are
now universal binaries.
- The Debian package now uses --verify-config when (re)starting,

2007-01-26 07:44:38 +01:00
Changes in version 0.1.1.24 - 2006-09-29
o Major bugfixes:
- Allow really slow clients to not hang up five minutes into their
directory downloads (suggested by Adam J. Richter).
- Fix major performance regression from 0.1.0.x: instead of checking
whether we have enough directory information every time we want to
do something, only check when the directory information has changed.
This should improve client CPU usage by 25-50%.
- Don't crash if, after a server has been running for a while,
it can't resolve its hostname.
o Minor bugfixes:
- Allow Tor to start when RunAsDaemon is set but no logs are set.
- Don't crash when the controller receives a third argument to an
"extendcircuit" request.
- Controller protocol fixes: fix encoding in "getinfo addr-mappings"

- Fix configure.in to not produce broken configure files with

- Fix security bug on NetBSD that could allow someone to force

- Warn user when using libevent 1.1a or earlier with win32 or kqueue
methods: these are known to be buggy.

Changes in version 0.1.2.1-alpha - 2006-08-27
o Major features:
- Add "eventdns" async dns library from Adam Langley, tweaked to
turn eventdns off by default until we can get some more useful log messages into it. no use learning that it's broken without being able to learn what is broken too. svn:r8245

build on OSX and Windows. Only enabled if you pass the
--enable-eventdns argument to configure.
clean up the 0.1.2.1-alpha changelog svn:r8240
2006-08-27 08:55:48 +02:00
- Allow servers with no hostname or IP address to learn their
IP address by asking the directory authorities. This code only
kicks in when you would normally have exited with a "no address"
error. Nothing's authenticated, so use with care.
- Rather than waiting a fixed amount of time between retrying
application connections, we wait only 5 seconds for the first,
10 seconds for the second, and 15 seconds for each retry after
that. Hopefully this will improve the expected user experience.
- Patch from Tup to add support for transparent AP connections:
this basically bundles the functionality of trans-proxy-tor
into the Tor mainline. Now hosts with compliant pf/netfilter
implementations can redirect TCP connections straight to Tor
without diverting through SOCKS. Needs docs.
- Busy directory servers save lots of memory by spooling server
descriptors, v1 directories, and v2 networkstatus docs to buffers
as needed rather than en masse. Also mmap the cached-routers
files, so we don't need to keep the whole thing in memory too.
- Automatically avoid picking more than one node from the same
/16 network when constructing a circuit.
- Revise and clean up the torrc.sample that we ship with; add
a section for BandwidthRate and BandwidthBurst.
o Minor features:
checkpoint in-progress changelog notes svn:r7054
2006-08-14 12:16:42 +02:00
- Split circuit_t into origin_circuit_t and or_circuit_t, and
split connection_t into edge, or, dir, control, and base structs.
These will save quite a bit of memory on busy servers, and they'll
clean up the 0.1.2.1-alpha changelog svn:r8240

also help us track down bugs in the code and bugs in the spec.
- Experimentally re-enable kqueue on OSX when using libevent 1.1b
or later. Log when we are doing this, so we can diagnose it when
it fails. (Also, recommend libevent 1.1b for kqueue and
win32 methods; deprecate libevent 1.0b harder; make libevent
recommendation system saner.)
- Start being able to build universal binaries on OS X (thanks
to Phobos).
checkpoint in-progress changelog notes svn:r7054
2006-08-14 12:16:42 +02:00

clean up the 0.1.2.1-alpha changelog svn:r8240
2006-08-27 08:55:48 +02:00
- Add a man page entry for ProtocolWarnings.
- Add TestVia config option to the man page.
- Remove even more protocol-related warnings from Tor server logs,
such as bad TLS handshakes and malformed begin cells.
- Stop fetching descriptors if you're not a dir mirror and you
haven't tried to establish any circuits lately. [This currently
causes some dangerous behavior, because when you start up again
you'll use your ancient server descriptors.]
- New DirPort behavior: if you have your dirport set, you download
descriptors aggressively like a directory mirror, whether or not
your ORPort is set.
checkpoint in-progress changelog notes svn:r7054
2006-08-14 12:16:42 +02:00
- Get rid of the router_retry_connections notion. Now routers
no longer try to rebuild long-term connections to directory
authorities, and directory authorities no longer try to rebuild
long-term connections to all servers. We still don't hang up
connections in these two cases though -- we need to look at it
more carefully to avoid flapping, and we likely need to wait til
0.1.1.x is obsolete.
clean up the 0.1.2.1-alpha changelog svn:r8240
2006-08-27 08:55:48 +02:00
- Drop compatibility with obsolete Tors that permit create cells

- Re-enable per-connection rate limiting. Get rid of the "OP
bandwidth" concept. Lay groundwork for "bandwidth classes" --
separate global buckets that apply depending on what sort of conn
it is.

2006-08-27 08:55:48 +02:00
o Major bugfixes:
- When we find our DirPort to be reachable, publish a new descriptor
so we'll tell the world (reported by pnx).
- Publish a new descriptor after we hup/reload. This is important
if our config has changed such that we'll want to start advertising
our DirPort now, etc.
- Allow Tor to start when RunAsDaemon is set but no logs are set.
- When we have a state file we cannot parse, tell the user and
move it aside. Now we avoid situations where the user starts
Tor in 1904, Tor writes a state file with that timestamp in it,
the user fixes her clock, and Tor refuses to start.
- Fix configure.in to not produce broken configure files with
more recent versions of autoconf. Thanks to Clint for his auto*
voodoo.
- "tor --verify-config" now exits with -1(255) or 0 depending on
whether the config options are bad or good.
- Resolve bug 321 when using dnsworkers: append a period to every
address we resolve at the exit node, so that we do not accidentally
pick up local addresses, and so that failing searches are retried
in the resolver search domains. (This is already solved for
eventdns.) (This breaks Blossom servers for now.)
- If we are using an exit enclave and we can't connect, e.g. because
its webserver is misconfigured to not listen on localhost, then
back off and try connecting from somewhere else before we fail.
o Minor bugfixes:
- Start compiling on MinGW on Windows (patches from Mike Chiussi).
- Start compiling on MSVC6 on Windows (patches from Frediano Ziglio).
- Fix bug 314: Tor clients issued "unsafe socks" warnings even
when the IP address is mapped through MapAddress to a hostname.
- Start passing "ipv4" hints to getaddrinfo(), so servers don't do
useless IPv6 DNS resolves.
- Patch suggested by Karsten Loesing: respond to SIGNAL command
before we execute the signal, in case the signal shuts us down.
- Clean up AllowInvalidNodes man page entry.
- Claim a commonname of Tor, rather than TOR, in TLS handshakes.
- Add more asserts to track down an assert error on a windows Tor
server with connection_add being called with socket == -1.
- Handle reporting OR_CONN_EVENT_NEW events to the controller.
checkpoint in-progress changelog notes svn:r7054
2006-08-14 12:16:42 +02:00
- Fix misleading log messages: an entry guard that is "unlisted",
as well as not known to be "down" (because we've never heard
of it), is not therefore "up".
- Remove code to special-case "-cvs" ending, since it has not
actually mattered since 0.0.9.
clean up the 0.1.2.1-alpha changelog svn:r8240
2006-08-27 08:55:48 +02:00

throw out everything waiting on the buffer in between socks
handshake phases, since they can't possibly (so the theory
goes) have predicted what we plan to respond to them.

forward-port the 0.1.1.23 changelog. svn:r6946
2006-07-30 07:36:17 +02:00
Changes in version 0.1.1.23 - 2006-07-30
o Major bugfixes:
- Fast Tor servers, especially exit nodes, were triggering asserts
due to a bug in handling the list of pending DNS resolves. Some
bugs still remain here; we're hunting them.
- Entry guards could crash clients by sending unexpected input.
- More fixes on reachability testing: if you find yourself reachable,
then don't ever make any client requests (so you stop predicting
circuits), then hup or have your clock jump, then later your IP
changes, you won't think circuits are working, so you won't try to
test reachability, so you won't publish.
o Minor bugfixes:
- Avoid a crash if the controller does a resetconf firewallports
and then a setconf fascistfirewall=1.
- Avoid an integer underflow when the dir authority decides whether
a router is stable: we might wrongly label it stable, and compute
a slightly wrong median stability, when a descriptor is published
later than now.
- Fix a place where we might trigger an assert if we can't build our
own server descriptor yet.
forward-port the 0.1.1.22 changelog, minus the line about the osx uninstaller. svn:r6738
2006-07-06 18:19:00 +02:00
Changes in version 0.1.1.22 - 2006-07-05
o Major bugfixes:
- Fix a big bug that was causing servers to not find themselves
reachable if they changed IP addresses. Since only 0.1.1.22+
servers can do reachability testing correctly, now we automatically
make sure to test via one of these.
- Fix to allow clients and mirrors to learn directory info from
descriptor downloads that get cut off partway through.
- Directory authorities had a bug in deciding if a newly published
descriptor was novel enough to make everybody want a copy -- a few
servers seem to be publishing new descriptors many times a minute.
o Minor bugfixes:
- Fix a rare bug that was causing some servers to complain about
"closing wedged cpuworkers" and skip some circuit create requests.
- Make the Exit flag in directory status documents actually work.
forward-port the 0.1.1.21 changelog. svn:r6600
2006-06-11 03:42:21 +02:00
Changes in version 0.1.1.21 - 2006-06-10
o Crash and assert fixes from 0.1.1.20:
- Fix a rare crash on Tor servers that have enabled hibernation.
- Fix a seg fault on startup for Tor networks that use only one
directory authority.
- Fix an assert from a race condition that occurs on Tor servers
while exiting, where various threads are trying to log that they're
exiting, and delete the logs, at the same time.
- Make our unit tests pass again on certain obscure platforms.
o Other fixes:
- Add support for building SUSE RPM packages.
- Speed up initial bootstrapping for clients: if we are making our
first ever connection to any entry guard, then don't mark it down
right after that.
- When only one Tor server in the network is labelled as a guard,
and we've already picked him, we would cycle endlessly picking him
again, being unhappy about it, etc. Now we specifically exclude
current guards when picking a new guard.
- Servers send create cells more reliably after the TLS connection
is established: we were sometimes forgetting to send half of them
when we had more than one pending.
- If we get a create cell that asks us to extend somewhere, but the
Tor server there doesn't match the expected digest, we now send
a destroy cell back, rather than silently doing nothing.
- Make options->RedirectExit work again.
- Make cookie authentication for the controller work again.
- Stop being picky about unusual characters in the arguments to
mapaddress. It's none of our business.
- Add a new config option "TestVia" that lets you specify preferred
middle hops to use for test circuits. Perhaps this will let me
debug the reachability problems better.
o Log / documentation fixes:
- If we're a server and some peer has a broken TLS certificate, don't
log about it unless ProtocolWarnings is set, i.e., we want to hear
about protocol violations by others.
- Fix spelling of VirtualAddrNetwork in man page.
- Add a better explanation at the top of the autogenerated torrc file
about what happened to our old torrc.

2007-01-26 07:34:48 +01:00
o Bugfixes:
- Downgrade a log severity where servers complain that they're
invalid.
- Avoid a compile warning on FreeBSD.
- Remove string size limit on NEWDESC messages; solve bug 291.
- Correct the RunAsDaemon entry in the man page; ignore RunAsDaemon
more thoroughly when we're running on windows.

Changes in version 0.1.1.19-rc - 2006-05-03
o Minor bugs:
- Regenerate our local descriptor if it's dirty and we try to use
it locally (e.g. if it changes during reachability detection).
- If we setconf our ORPort to 0, we continued to listen on the
old ORPort and receive connections.
- Avoid a second warning about machine/limits.h on Debian
GNU/kFreeBSD.
- Be willing to add our own routerinfo into the routerlist.
Now authorities will include themselves in their directories
and network-statuses.
- Stop trying to upload rendezvous descriptors to every
directory authority: only try the v1 authorities.
- Servers no longer complain when they think they're not
registered with the directory authorities. There were too many
false positives.
- Backport dist-rpm changes so rpms can be built without errors.

break out 0.1.1 changelog entries svn:r9418
2007-01-26 07:34:48 +01:00
o Features:
- Implement an option, VirtualAddrMask, to set which addresses
get handed out in response to mapaddress requests. This works
around a bug in tsocks where 127.0.0.0/8 is never socksified.
Changes in version 0.1.1.18-rc - 2006-04-10
o Major fixes:
- Work harder to download live network-statuses from all the
directory authorities we know about. Improve the threshold
decision logic so we're more robust to edge cases.
- When fetching rendezvous descriptors, we were willing to ask
v2 authorities too, which would always return 404.
o Minor fixes:
- Stop listing down or invalid nodes in the v1 directory. This will
reduce its bulk by about 1/3, and reduce load on directory
mirrors.
- When deciding whether a router is Fast or Guard-worthy, consider
his advertised BandwidthRate and not just the BandwidthCapacity.
- No longer ship INSTALL and README files -- they are useless now.
- Force rpmbuild to behave and honor target_cpu.

- Avoid warnings about machine/limits.h on Debian GNU/kFreeBSD.
break out 0.1.1 changelog entries svn:r9418
2007-01-26 07:34:48 +01:00
- Start to include translated versions of the tor-doc-*.html
files, along with the screenshots. Still needs more work.
- Start sending back 512 and 451 errors if mapaddress fails,
rather than not sending anything back at all.
- When we fail to bind or listen on an incoming or outgoing
socket, we should close it before failing. otherwise we just
leak it. (thanks to weasel for finding.)
- Allow "getinfo dir/status/foo" to work, as long as your DirPort
is enabled. (This is a hack, and will be fixed in 0.1.2.x.)
- Make NoPublish (even though deprecated) work again.
- Fix a minor security flaw where a versioning auth dirserver
could list a recommended version many times in a row to make
clients more convinced that it's recommended.
- Fix crash bug if there are two unregistered servers running
with the same nickname, one of them is down, and you ask for
them by nickname in your EntryNodes or ExitNodes. Also, try
to pick the one that's running rather than an arbitrary one.
- Fix an infinite loop we could hit if we go offline for too long.
- Complain when we hit WSAENOBUFS on recv() or write() too.
Perhaps this will help us hunt the bug.
- If you're not a versioning dirserver, don't put the string
"client-versions \nserver-versions \n" in your network-status.
- Lower the minimum required number of file descriptors to 1000,
so we can have some overhead for Valgrind on Linux, where the
default ulimit -n is 1024.

o New features:
- Add tor.dizum.com as the fifth authoritative directory server.
- Add a new config option FetchUselessDescriptors, off by default,
for when you plan to run "exitlist" on your client and you want
to know about even the non-running descriptors.

2007-01-26 07:34:48 +01:00
Changes in version 0.1.1.17-rc - 2006-03-28
o Major fixes:
- Clients and servers since 0.1.1.10-alpha have been expiring
connections whenever they are idle for 5 minutes and they *do*
have circuits on them. Oops. With this new version, clients will
discard their previous entry guard choices and avoid choosing
entry guards running these flawed versions.
- Fix memory leak when uncompressing concatenated zlib streams. This
was causing substantial leaks over time on Tor servers.
- The v1 directory was including servers as much as 48 hours old,
because that's how the new routerlist->routers works. Now only
include them if they're 20 hours old or less.
o Minor fixes:
- Resume building on irix64, netbsd 2.0, etc.
- On non-gcc compilers (e.g. solaris), use "-g -O" instead of
"-Wall -g -O2".
- Stop writing the "router.desc" file, ever. Nothing uses it anymore,
and it is confusing some users.
- Mirrors stop caching the v1 directory so often.
- Make the max number of old descriptors that a cache will hold
rise with the number of directory authorities, so we can scale.
- Change our win32 uname() hack to be more forgiving about what
win32 versions it thinks it's found.
o New features:
- Add lefkada.eecs.harvard.edu as a fourth authoritative directory
server.
- When the controller's *setconf commands fail, collect an error
message in a string and hand it back to the controller.

2006-05-23 08:20:35 +02:00
- Make the v2 dir's "Fast" flag based on relative capacity, just
like "Stable" is based on median uptime. Name everything in the
top 7/8 Fast, and only the top 1/2 gets to be a Guard.

have to go hunting around their filesystem for it.

- Let the controller ask for GETINFO dir/status/foo so it can ask
directly rather than connecting to the dir port. Only works when
dirport is set for now.

2007-01-26 07:34:48 +01:00
o New config options rather than constants in the code:
- SocksTimeout: How long do we let a socks connection wait
unattached before we fail it?
- CircuitBuildTimeout: Cull non-open circuits that were born
at least this many seconds ago.
- CircuitIdleTimeout: Cull open clean circuits that were born
at least this many seconds ago.
Changes in version 0.1.1.16-rc - 2006-03-18
o Bugfixes on 0.1.1.15-rc:
- Fix assert when the controller asks to attachstream a connect-wait
or resolve-wait stream.
- Now do address rewriting when the controller asks us to attach
to a particular circuit too. This will let Blossom specify
"moria2.exit" without having to learn what moria2's IP address is.
- Make the "tor --verify-config" command-line work again, so people
can automatically check if their torrc will parse.
- Authoritative dirservers no longer require an open connection from
a server to consider him "reachable". We need this change because
when we add new auth dirservers, old servers won't know not to
hang up on them.
- Let Tor build on Sun CC again.
- Fix an off-by-one buffer size in dirserv.c that magically never
hit our three authorities but broke sjmurdoch's own tor network.
- If we as a directory mirror don't know of any v1 directory
authorities, then don't try to cache any v1 directories.
- Stop warning about unknown servers in our family when they are
given as hex digests.
- Stop complaining as quickly to the server operator that he
hasn't registered his nickname/key binding.
- Various cleanups so we can add new V2 Auth Dirservers.
- Change "AllowUnverifiedNodes" to "AllowInvalidNodes", to
reflect the updated flags in our v2 dir protocol.
- Resume allowing non-printable characters for exit streams (both
for connecting and for resolving). Now we tolerate applications
that don't follow the RFCs. But continue to block malformed names
at the socks side.
o Bugfixes on 0.1.0.x:
- Fix assert bug in close_logs(): when we close and delete logs,
remove them all from the global "logfiles" list.
- Fix minor integer overflow in calculating when we expect to use up
our bandwidth allocation before hibernating.
- Fix a couple of bugs in OpenSSL detection. Also, deal better when
there are multiple SSLs installed with different versions.
- When we try to be a server and Address is not explicitly set and
our hostname resolves to a private IP address, try to use an
interface address if it has a public address. Now Windows machines
that think of themselves as localhost can work by default.
o New features:
- Let the controller ask for GETINFO dir/server/foo so it can ask
directly rather than connecting to the dir port.

2006-05-22 22:00:12 +02:00
- Let the controller tell us about certain router descriptors
that it doesn't want Tor to use in circuits. Implement
break out 0.1.1 changelog entries svn:r9418
2007-01-26 07:34:48 +01:00
SETROUTERPURPOSE and modify +POSTDESCRIPTOR to do this.
- New config option SafeSocks to reject all application connections
using unsafe socks protocols. Defaults to off.
Changes in version 0.1.1.15-rc - 2006-03-11
o Bugfixes and cleanups:
- When we're printing strings from the network, don't try to print
non-printable characters. This protects us against shell escape
sequence exploits, and also against attacks to fool humans into
misreading their logs.
- Fix a bug where Tor would fail to establish any connections if you
left it off for 24 hours and then started it: we were happy with
the obsolete network statuses, but they all referred to router
descriptors that were too old to fetch, so we ended up with no
valid router descriptors.
- Fix a seg fault in the controller's "getinfo orconn-status"
command while listing status on incoming handshaking connections.
Introduce a status name "NEW" for these connections.
- If we get a linelist or linelist_s config option from the torrc
(e.g. ExitPolicy) and it has no value, warn and skip rather than
silently resetting it to its default.
- Don't abandon entry guards until they've been down or gone for
a whole month.
- Cleaner and quieter log messages.
o New features:
- New controller signal NEWNYM that makes new application requests
use clean circuits.
- Add a new circuit purpose 'controller' to let the controller ask
for a circuit that Tor won't try to use. Extend the EXTENDCIRCUIT
controller command to let you specify the purpose if you're
starting a new circuit. Add a new SETCIRCUITPURPOSE controller
command to let you change a circuit's purpose after it's been
created.
- Accept "private:*" in routerdesc exit policies; not generated yet
because older Tors do not understand it.
- Add BSD-style contributed startup script "rc.subr" from Peter
Thoenen.
Changes in version 0.1.1.14-alpha - 2006-02-20
o Bugfixes on 0.1.1.x:
- Don't die if we ask for a stdout or stderr log (even implicitly)
and we're set to RunAsDaemon -- just warn.
- We still had a few bugs in the OR connection rotation code that
caused directory servers to slowly aggregate connections to other
fast Tor servers. This time for sure!
- Make log entries on Win32 include the name of the function again.
- We were treating a pair of exit policies if they were equal even
if one said accept and the other said reject -- causing us to
not always publish a new descriptor since we thought nothing
had changed.
- Retry pending server downloads as well as pending networkstatus
downloads when we unexpectedly get a socks request.
- We were ignoring the IS_FAST flag in the directory status,
meaning we were willing to pick trivial-bandwidth nodes for "fast"
connections.
- If the controller's SAVECONF command fails (e.g. due to file
permissions), let the controller know that it failed.
o Features:
- If we're trying to be a Tor server and running Windows 95/98/ME
as a server, explain that we'll likely crash.
- When we're a server, a client asks for an old-style directory,
and our write bucket is empty, don't give it to him. This way
small servers can continue to serve the directory *sometimes*,
without getting overloaded.
- Compress exit policies even more -- look for duplicate lines
and remove them.
- Clients now honor the "guard" flag in the router status when
picking entry guards, rather than looking at is_fast or is_stable.
- Retain unrecognized lines in $DATADIR/state file, so that we can
be forward-compatible.
- Generate 18.0.0.0/8 address policy format in descs when we can;
warn when the mask is not reducible to a bit-prefix.
- Let the user set ControlListenAddress in the torrc. This can be
dangerous, but there are some cases (like a secured LAN) where it
makes sense.
- Split ReachableAddresses into ReachableDirAddresses and
ReachableORAddresses, so we can restrict Dir conns to port 80
and OR conns to port 443.
- Now we can target arch and OS in rpm builds (contributed by
Phobos). Also make the resulting dist-rpm filename match the
target arch.
- New config options to help controllers: FetchServerDescriptors
and FetchHidServDescriptors for whether to fetch server
info and hidserv info or let the controller do it, and
PublishServerDescriptor and PublishHidServDescriptors.
- Also let the controller set the __AllDirActionsPrivate config
option if you want all directory fetches/publishes to happen via
Tor (it assumes your controller bootstraps your circuits).
Changes in version 0.1.0.17 - 2006-02-17
o Crash bugfixes on 0.1.0.x:
- When servers with a non-zero DirPort came out of hibernation,
sometimes they would trigger an assert.
o Other important bugfixes:
- On platforms that don't have getrlimit (like Windows), we were
artificially constraining ourselves to a max of 1024
connections. Now just assume that we can handle as many as 15000
connections. Hopefully this won't cause other problems.
o Backported features:
- When we're a server, a client asks for an old-style directory,
and our write bucket is empty, don't give it to him. This way
small servers can continue to serve the directory *sometimes*,
without getting overloaded.
- Whenever you get a 503 in response to a directory fetch, try
once more. This will become important once servers start sending
503's whenever they feel busy.
- Fetch a new directory every 120 minutes, not every 40 minutes.
Now that we have hundreds of thousands of users running the old
directory algorithm, it's starting to hurt a lot.
- Bump up the period for forcing a hidden service descriptor upload
from 20 minutes to 1 hour.

Changes in version 0.1.1.13-alpha - 2006-02-09
o Crashes in 0.1.1.x:
- When you tried to setconf ORPort via the controller, Tor would
crash. So people using TorCP to become a server were sad.
- Solve (I hope) the stack-smashing bug that we were seeing on fast
servers. The problem appears to be something do with OpenSSL's
random number generation, or how we call it, or something. Let me
know if the crashes continue.
- Turn crypto hardware acceleration off by default, until we find
somebody smart who can test it for us. (It appears to produce
seg faults in at least some cases.)
- Fix a rare assert error when we've tried all intro points for
a hidden service and we try fetching the service descriptor again:
"Assertion conn->state != AP_CONN_STATE_RENDDESC_WAIT failed"
o Major fixes:
- Fix a major load balance bug: we were round-robining in 16 KB
continue messing with the changelog. it's getting better now. svn:r6468
2006-05-23 08:20:35 +02:00
chunks, and servers with bandwidthrate of 20 KB, while downloading
a 600 KB directory, would starve their other connections. Now we
try to be a bit more fair.
break out 0.1.1 changelog entries svn:r9418
2007-01-26 07:34:48 +01:00
- Dir authorities and mirrors were never expiring the newest
descriptor for each server, causing memory and directory bloat.
- Fix memory-bloating and connection-bloating bug on servers: We
were never closing any connection that had ever had a circuit on
it, because we were checking conn->n_circuits == 0, yet we had a
bug that let it go negative.
- Make Tor work using squid as your http proxy again -- squid
returns an error if you ask for a URL that's too long, and it uses
a really generic error message. Plus, many people are behind a
transparent squid so they don't even realize it.
- On platforms that don't have getrlimit (like Windows), we were
artificially constraining ourselves to a max of 1024
connections. Now just assume that we can handle as many as 15000
connections. Hopefully this won't cause other problems.
- Add a new config option ExitPolicyRejectPrivate which defaults to
1. This means all exit policies will begin with rejecting private
addresses, unless the server operator explicitly turns it off.
o Major features:
changelog entry for r11985 (bug 529) svn:r12034
2007-10-19 01:14:42 +02:00
- Clients no longer download descriptors for non-running
break out 0.1.1 changelog entries svn:r9418
2007-01-26 07:34:48 +01:00
descriptors.
- Before we add new directory authorities, we should make it
clear that only v1 authorities should receive/publish hidden
service descriptors.
o Minor features:
- As soon as we've fetched some more directory info, immediately
try to download more server descriptors. This way we don't have
a 10 second pause during initial bootstrapping.
- Remove even more loud log messages that the server operator can't
do anything about.
- When we're running an obsolete or un-recommended version, make
the log message more clear about what the problem is and what
versions *are* still recommended.
- Provide a more useful warn message when our onion queue gets full:
the CPU is too slow or the exit policy is too liberal.
- Don't warn when we receive a 503 from a dirserver/cache -- this
will pave the way for them being able to refuse if they're busy.
- When we fail to bind a listener, try to provide a more useful
log message: e.g., "Is Tor already running?"
- Adjust tor-spec to parameterize cell and key lengths. Now Ian
Goldberg can prove things about our handshake protocol more
easily.
- MaxConn has been obsolete for a while now. Document the ConnLimit
config option, which is a *minimum* number of file descriptors
that must be available else Tor refuses to start.
- Apply Matt Ghali's --with-syslog-facility patch to ./configure
if you log to syslog and want something other than LOG_DAEMON.
- Make dirservers generate a separate "guard" flag to mean,
"would make a good entry guard". Make clients parse it and vote
on it. Not used by clients yet.
- Implement --with-libevent-dir option to ./configure. Also, improve
search techniques to find libevent, and use those for openssl too.
- Bump the default bandwidthrate to 3 MB, and burst to 6 MB
- Only start testing reachability once we've established a
circuit. This will make startup on dirservers less noisy.
- Don't try to upload hidden service descriptors until we have
established a circuit.
- Fix the controller's "attachstream 0" command to treat conn like
it just connected, doing address remapping, handling .exit and
.onion idioms, and so on. Now we're more uniform in making sure
that the controller hears about new and closing connections.
Changes in version 0.1.1.12-alpha - 2006-01-11
o Bugfixes on 0.1.1.x:
- The fix to close duplicate server connections was closing all
Tor client connections if they didn't establish a circuit
quickly enough. Oops.
- Fix minor memory issue (double-free) that happened on exit.
o Bugfixes on 0.1.0.x:
- Tor didn't warn when it failed to open a log file.

Changes in version 0.1.1.11-alpha - 2006-01-10
o Crashes in 0.1.1.x:
- Include all the assert/crash fixes from 0.1.0.16.
- If you start Tor and then quit very quickly, there were some
races that tried to free things that weren't allocated yet.
- Fix a rare memory stomp if you're running hidden services.
- Fix segfault when specifying DirServer in config without nickname.
- Fix a seg fault when you finish connecting to a server but at
that moment you dump his server descriptor.
- Extendcircuit and Attachstream controller commands would
assert/crash if you don't give them enough arguments.
- Fix an assert error when we're out of space in the connection_list
and we try to post a hidden service descriptor (reported by weasel).
- If you specify a relative torrc path and you set RunAsDaemon in
your torrc, then it chdir()'s to the new directory. If you HUP,
it tries to load the new torrc location, fails, and exits.
The fix: no longer allow a relative path to torrc using -f.
o Major features:
- Implement "entry guards": automatically choose a handful of entry
nodes and stick with them for all circuits. Only pick new guards
when the ones you have are unsuitable, and if the old guards
become suitable again, switch back. This will increase security
dramatically against certain end-point attacks. The EntryNodes
config option now provides some hints about which entry guards you
want to use most; and StrictEntryNodes means to only use those.
- New directory logic: download by descriptor digest, not by
fingerprint. Caches try to download all listed digests from
authorities; clients try to download "best" digests from caches.
This avoids partitioning and isolating attacks better.
- Make the "stable" router flag in network-status be the median of
the uptimes of running valid servers, and make clients pay
attention to the network-status flags. Thus the cutoff adapts
to the stability of the network as a whole, making IRC, IM, etc
connections more reliable.

- Tor servers with dynamic IP addresses were needing to wait 18
hours before they could start doing reachability testing using
the new IP address and ports. This is because they were using
the internal descriptor to learn what to test, yet they were only
rebuilding the descriptor once they decided they were reachable.

2007-01-26 07:34:48 +01:00
- Tor 0.1.1.9 and 0.1.1.10 had a serious bug that caused clients
to download certain server descriptors, throw them away, and then
fetch them again after 30 minutes. Now mirrors throw away these
server descriptors so clients can't get them.
- We were leaving duplicate connections to other ORs open for a week,
rather than closing them once we detect a duplicate. This only
really affected authdirservers, but it affected them a lot.
- Spread the authdirservers' reachability testing over the entire
testing interval, so we don't try to do 500 TLS's at once every
20 minutes.
o Minor fixes:
- If the network is down, and we try to connect to a conn because
we have a circuit in mind, and we timeout (30 seconds) because the
network never answers, we were expiring the circuit, but we weren't
obsoleting the connection or telling the entry_guards functions.
- Some Tor servers process billions of cells per day. These statistics
need to be uint64_t's.
- Check for integer overflows in more places, when adding elements
to smartlists. This could possibly prevent a buffer overflow
on malicious huge inputs. I don't see any, but I haven't looked
carefully.
- ReachableAddresses kept growing new "reject *:*" lines on every
setconf/reload.
- When you "setconf log" via the controller, it should remove all
logs. We were automatically adding back in a "log notice stdout".

- Newly bootstrapped Tor networks couldn't establish hidden service
circuits until they had nodes with high uptime. Be more tolerant.
break out 0.1.1 changelog entries svn:r9418
2007-01-26 07:34:48 +01:00
- We were marking servers down when they could not answer every piece
of the directory request we sent them. This was far too harsh.
- Fix the torify (tsocks) config file to not use Tor for localhost
connections.
- Directory authorities now go to the proper authority when asking for
a networkstatus, even when they want a compressed one.
- Fix a harmless bug that was causing Tor servers to log
"Got an end because of misc error, but we're not an AP. Closing."
- Authorities were treating their own descriptor changes as cosmetic,
meaning the descriptor available in the network-status and the
descriptor that clients downloaded were different.
- The OS X installer was adding a symlink for tor_resolve but
the binary was called tor-resolve (reported by Thomas Hardly).
- Workaround a problem with some http proxies where they refuse GET
requests that specify "Content-Length: 0" (reported by Adrian).
- Fix wrong log message when you add a "HiddenServiceNodes" config
line without any HiddenServiceDir line (reported by Chris Thomas).
o Minor features:
- Write the TorVersion into the state file so we have a prayer of
keeping forward and backward compatibility.
- Revive the FascistFirewall config option rather than eliminating it:
now it's a synonym for ReachableAddresses *:80,*:443.
- Clients choose directory servers from the network status lists,
not from their internal list of router descriptors. Now they can
go to caches directly rather than needing to go to authorities
to bootstrap.
- Directory authorities ignore router descriptors that have only
cosmetic differences: do this for 0.1.0.x servers now too.
- Add a new flag to network-status indicating whether the server
can answer v2 directory requests too.
- Authdirs now stop whining so loudly about bad descriptors that
they fetch from other dirservers. So when there's a log complaint,
it's for sure from a freshly uploaded descriptor.
- Reduce memory requirements in our structs by changing the order
of fields.
- There used to be two ways to specify your listening ports in a
server descriptor: on the "router" line and with a separate "ports"
line. Remove support for the "ports" line.
- New config option "AuthDirRejectUnlisted" for auth dirservers as
a panic button: if we get flooded with unusable servers we can
revert to only listing servers in the approved-routers file.
- Auth dir servers can now mark a fingerprint as "!reject" or
"!invalid" in the approved-routers file (as its nickname), to
refuse descriptors outright or include them but marked as invalid.
- Servers store bandwidth history across restarts/crashes.
- Add reasons to DESTROY and RELAY_TRUNCATED cells, so clients can
get a better idea of why their circuits failed. Not used yet.
- Directory mirrors now cache up to 16 unrecognized network-status
docs. Now we can add new authdirservers and they'll be cached too.
- When picking a random directory, prefer non-authorities if any
are known.
- New controller option "getinfo desc/all-recent" to fetch the
latest server descriptor for every router that Tor knows about.
Changes in version 0.1.0.16 - 2006-01-02
o Crash bugfixes on 0.1.0.x:
- On Windows, build with a libevent patch from "I-M Weasel" to avoid
corrupting the heap, losing FDs, or crashing when we need to resize
the fd_sets. (This affects the Win32 binaries, not Tor's sources.)
- It turns out sparc64 platforms crash on unaligned memory access
too -- so detect and avoid this.
- Handle truncated compressed data correctly (by detecting it and
giving an error).
- Fix possible-but-unlikely free(NULL) in control.c.
- When we were closing connections, there was a rare case that
stomped on memory, triggering seg faults and asserts.
- Avoid potential infinite recursion when building a descriptor. (We
don't know that it ever happened, but better to fix it anyway.)
- We were neglecting to unlink marked circuits from soon-to-close OR
connections, which caused some rare scribbling on freed memory.
- Fix a memory stomping race bug when closing the joining point of two
rendezvous circuits.
- Fix an assert in time parsing found by Steven Murdoch.
o Other bugfixes on 0.1.0.x:
- When we're doing reachability testing, provide more useful log
messages so the operator knows what to expect.
- Do not check whether DirPort is reachable when we are suppressing
advertising it because of hibernation.
- When building with -static or on Solaris, we sometimes needed -ldl.
- When we're deciding whether a stream has enough circuits around
that can handle it, count the freshly dirty ones and not the ones
that are so dirty they won't be able to handle it.
- When we're expiring old circuits, we had a logic error that caused
us to close new rendezvous circuits rather than old ones.
- Give a more helpful log message when you try to change ORPort via
the controller: you should upgrade Tor if you want that to work.
- We were failing to parse Tor versions that start with "Tor ".
- Tolerate faulty streams better: when a stream fails for reason
exitpolicy, stop assuming that the router is lying about his exit
policy. When a stream fails for reason misc, allow it to retry just
as if it was resolvefailed. When a stream has failed three times,
reset its failure count so we can try again and get all three tries.
Changes in version 0.1.1.10-alpha - 2005-12-11
o Correctness bugfixes on 0.1.0.x:
- On Windows, build with a libevent patch from "I-M Weasel" to avoid
corrupting the heap, losing FDs, or crashing when we need to resize
the fd_sets. (This affects the Win32 binaries, not Tor's sources.)
- Stop doing the complex voodoo overkill checking for insecure
Diffie-Hellman keys. Just check if it's in [2,p-2] and be happy.
- When we were closing connections, there was a rare case that
stomped on memory, triggering seg faults and asserts.
- We were neglecting to unlink marked circuits from soon-to-close OR
connections, which caused some rare scribbling on freed memory.
- When we're deciding whether a stream has enough circuits around
that can handle it, count the freshly dirty ones and not the ones
that are so dirty they won't be able to handle it.

o Security bugfixes on 0.1.0.x:
- Refuse server descriptors if the fingerprint line doesn't match
the included identity key. Tor doesn't care, but other apps (and
humans) might actually be trusting the fingerprint line.
- We used to kill the circuit when we receive a relay command we
don't recognize. Now we just drop it.
- Start obeying our firewall options more rigorously:
. If we can't get to a dirserver directly, try going via Tor.
. Don't ever try to connect (as a client) to a place our
firewall options forbid.
. If we specify a proxy and also firewall options, obey the
firewall options even when we're using the proxy: some proxies
can only proxy to certain destinations.
- Fix a bug found by Lasse Overlier: when we were making internal
circuits (intended to be cannibalized later for rendezvous and
introduction circuits), we were picking them so that they had
useful exit nodes. There was no need for this, and it actually
aids some statistical attacks.
- Start treating internal circuits and exit circuits separately.
It's important to keep them separate because internal circuits
have their last hops picked like middle hops, rather than like
exit hops. So exiting on them will break the user's expectations.

o Bugfixes on 0.1.1.x:
- Take out the mis-feature where we tried to detect IP address
flapping for people with DynDNS, and chose not to upload a new
server descriptor sometimes.
- Try to be compatible with OpenSSL 0.9.6 again.
- Log fix: when the controller is logging about .onion addresses,
sometimes it didn't include the ".onion" part of the address.
- Don't try to modify options->DirServers internally -- if the
user didn't specify any, just add the default ones directly to
the trusted dirserver list. This fixes a bug where people running
controllers would use SETCONF on some totally unrelated config
option, and Tor would start yelling at them about changing their
DirServer lines.
- Let the controller's redirectstream command specify a port, in
case the controller wants to change that too.
- When we requested a pile of server descriptors, we sometimes
accidentally launched a duplicate request for the first one.
- Bugfix for trackhostexits: write down the fingerprint of the
chosen exit, not its nickname, because the chosen exit might not
be verified.
- When parsing foo.exit, if foo is unknown, and we are leaving
circuits unattached, set the chosen_exit field and leave the
address empty. This matters because controllers got confused
otherwise.
- Directory authorities no longer try to download server
descriptors that they know they will reject.
o Features and updates:
- Replace balanced trees with hash tables: this should make stuff
significantly faster.
- Resume using the AES counter-mode implementation that we ship,
rather than OpenSSL's. Ours is significantly faster.
- Many other CPU and memory improvements.

2006-05-22 22:00:12 +02:00

- Warn when listening on a public address for socks. I suspect a
lot of people are setting themselves up as open socks proxies,
and they have no idea that jerks on the Internet are using them,
since they simply proxy the traffic into the Tor network.

2006-05-22 22:00:12 +02:00

o Usability improvements:

or port.

2006-05-22 22:00:12 +02:00
- Reduce clutter in server logs. We're going to try to make
them actually usable now. New config option ProtocolWarnings that
lets you hear about how _other Tors_ are breaking the protocol. Off
by default.
- Divide log messages into logging domains. Once we put some sort
of interface on this, it will let people looking at more verbose
break out 0.1.1 changelog entries svn:r9418
2007-01-26 07:34:48 +01:00
log levels specify the topics they want to hear more about.
- Make directory servers return better http 404 error messages
instead of a generic "Servers unavailable".
- Check for even more Windows version flags when writing the platform
string in server descriptors, and note any we don't recognize.
- Clean up more of the OpenSSL memory when exiting, so we can detect
memory leaks better.
- Make directory authorities be non-versioning, non-naming by
default. Now we can add new directory servers without requiring
their operators to pay close attention.

o Performance improvements:
- Directory servers now silently throw away new descriptors that
haven't changed much if the timestamps are similar. We do this to
tolerate older Tor servers that upload a new descriptor every 15
minutes. (It seemed like a good idea at the time.)
- Inline bottleneck smartlist functions; use fast versions by default.
- Add a "Map from digest to void*" abstraction digestmap_t so we
can do less hex encoding/decoding. Use it in router_get_by_digest()
to resolve a performance bottleneck.
- Allow tor_gzip_uncompress to extract as much as possible from
truncated compressed data. Try to extract as many
descriptors as possible from truncated http responses (when
DIR_PURPOSE_FETCH_ROUTERDESC).
- Make circ->onionskin a pointer, not a static array. moria2 was using
125000 circuit_t's after it had been up for a few weeks, which
translates to 20+ megs of wasted space.
- The private half of our EDH handshake keys are now chosen out
of 320 bits, not 1024 bits. (Suggested by Ian Goldberg.)

o Security improvements:

clients can start asking by digest of descriptor rather than by
fingerprint of server.
- Add half our entropy from RAND_poll in OpenSSL. This knows how
to use egd (if present), openbsd weirdness (if present), vms/os2
weirdness (if we ever port there), and more in the future.

o Bugfixes on 0.1.0.x:
- Do round-robin writes of at most 16 kB per write. This might be
more fair on loaded Tor servers, and it might resolve our Windows
crash bug. It might also slow things down.
- Our TLS handshakes were generating a single public/private
keypair for the TLS context, rather than making a new one for
each new connections. Oops. (But we were still rotating them
periodically, so it's not so bad.)
- When we were cannibalizing a circuit with a particular exit
node in mind, we weren't checking to see if that exit node was
already present earlier in the circuit. Oops.
- When a Tor server's IP changes (e.g. from a dyndns address),
upload a new descriptor so clients will learn too.
- Really busy servers were keeping enough circuits open on stable
connections that they were wrapping around the circuit_id
space. (It's only two bytes.) This exposed a bug where we would
feel free to reuse a circuit_id even if it still exists but has
been marked for close. Try to fix this bug. Some bug remains.
- If we would close a stream early (e.g. it asks for a .exit that
we know would refuse it) but the LeaveStreamsUnattached config
option is set by the controller, then don't close it.

o Bugfixes on 0.1.1.8-alpha:
- Fix a big pile of memory leaks, some of them serious.
- Do not try to download a routerdesc if we would immediately reject
it as obsolete.
- Resume inserting a newline between all router descriptors when
generating (old style) signed directories, since our spec says
we do.
- When providing content-type application/octet-stream for
server descriptors using .z, we were leaving out the
content-encoding header. Oops. (Everything tolerated this just
fine, but that doesn't mean we need to be part of the problem.)
- Fix a potential seg fault in getconf and getinfo using version 1
of the controller protocol.
- Avoid crash: do not check whether DirPort is reachable when we
are suppressing it because of hibernation.
- Make --hash-password not crash on exit.
Changes in version 0.1.1.8-alpha - 2005-10-07
o New features (major):
- Clients don't download or use the directory anymore. Now they
download and use network-statuses from the trusted dirservers,
and fetch individual server descriptors as needed from mirrors.
See dir-spec.txt for all the gory details.
- Be more conservative about whether to advertise our DirPort.
The main change is to not advertise if we're running at capacity
and either a) we could hibernate or b) our capacity is low and
we're using a default DirPort.
- Use OpenSSL's AES when OpenSSL has version 0.9.7 or later.

o New features (minor):
- Try to be smart about when to retry network-status and
server-descriptor fetches. Still needs some tuning.
- Stop parsing, storing, or using running-routers output (but
mirrors still cache and serve it).
- Consider a threshold of versioning dirservers (dirservers who have
an opinion about which Tor versions are still recommended) before
deciding whether to warn the user that he's obsolete.
- Dirservers can now reject/invalidate by key and IP, with the
config options "AuthDirInvalid" and "AuthDirReject". This is
useful since currently we automatically list servers as running
and usable even if we know they're jerks.
- Provide dire warnings to any users who set DirServer; move it out
of torrc.sample and into torrc.complete.
- Add MyFamily to torrc.sample in the server section.
- Add nicknames to the DirServer line, so we can refer to them
without requiring all our users to memorize their IP addresses.
- When we get an EOF or a timeout on a directory connection, note
how many bytes of serverdesc we are dropping. This will help
us determine whether it is smart to parse incomplete serverdesc
responses.
- Add a new function to "change pseudonyms" -- that is, to stop
using any currently-dirty circuits for new streams, so we don't
link new actions to old actions. Currently it's only called on
HUP (or SIGNAL RELOAD).
- On sighup, if UseHelperNodes changed to 1, use new circuits.
- Start using RAND_bytes rather than RAND_pseudo_bytes from
OpenSSL. Also, reseed our entropy every hour, not just at
startup. And entropy in 512-bit chunks, not 160-bit chunks.
o Fixes on 0.1.1.7-alpha:
- Nobody ever implemented EVENT_ADDRMAP for control protocol
version 0, so don't let version 0 controllers ask for it.
- If you requested something with too many newlines via the
v1 controller protocol, you could crash tor.
- Fix a number of memory leaks, including some pretty serious ones.
- Re-enable DirPort testing again, so Tor servers will be willing
to advertise their DirPort if it's reachable.
- On TLS handshake, only check the other router's nickname against
its expected nickname if is_named is set.
o Fixes forward-ported from 0.1.0.15:
- Don't crash when we don't have any spare file descriptors and we
try to spawn a dns or cpu worker.
- Make the numbers in read-history and write-history into uint64s,
so they don't overflow and publish negatives in the descriptor.

o Fixes on 0.1.0.x:
- For the OS X package's modified privoxy config file, comment
out the "logfile" line so we don't log everything passed
through privoxy.
- We were whining about using socks4 or socks5-with-local-lookup
even when it's an IP in the "virtual" range we designed exactly
for this case.
- We were leaking some memory every time the client changes IPs.
- Never call free() on tor_malloc()d memory. This will help us
use dmalloc to detect memory leaks.
- Check for named servers when looking them up by nickname;
warn when we'recalling a non-named server by its nickname;
don't warn twice about the same name.
- Try to list MyFamily elements by key, not by nickname, and warn
if we've not heard of the server.
- Make windows platform detection (uname equivalent) smarter.
- It turns out sparc64 doesn't like unaligned access either.

- Looking up a non-existent stream for a v1 control connection would

o Fixes on 0.1.0.x:
- If the user gave tor an odd number of command-line arguments,
we were silently ignoring the last one. Now we complain and fail.
[This wins the oldest-bug prize -- this bug has been present since
November 2002, as released in Tor 0.0.0.]
- Do not use unaligned memory access on alpha, mips, or mipsel.
It *works*, but is very slow, so we treat them as if it doesn't.
- Retry directory requests if we fail to get an answer we like
from a given dirserver (we were retrying before, but only if
we fail to connect).
- When writing the RecommendedVersions line, sort them first.
- When the client asked for a rendezvous port that the hidden
service didn't want to provide, we were sending an IP address
back along with the end cell. Fortunately, it was zero. But stop
that anyway.
- Correct "your server is reachable" log entries to indicate that
it was self-testing that told us so.
Changes in version 0.1.1.6-alpha - 2005-09-09
o Fixes on 0.1.1.5-alpha:
- We broke fascistfirewall in 0.1.1.5-alpha. Oops.
- Fix segfault in unit tests in 0.1.1.5-alpha. Oops.
- Fix bug with tor_memmem finding a match at the end of the string.
- Make unit tests run without segfaulting.
- Resolve some solaris x86 compile warnings.
- Handle duplicate lines in approved-routers files without warning.
- Fix bug where as soon as a server refused any requests due to his
exit policy (e.g. when we ask for localhost and he tells us that's
127.0.0.1 and he won't do it), we decided he wasn't obeying his
exit policy using him for any exits.
- Only do openssl hardware accelerator stuff if openssl version is
at least 0.9.7.
o New controller features/fixes:
- Add a "RESETCONF" command so you can set config options like
AllowUnverifiedNodes and LongLivedPorts to "". Also, if you give
a config option in the torrc with no value, then it clears it
entirely (rather than setting it to its default).
- Add a "GETINFO config-file" to tell us where torrc is.
- Avoid sending blank lines when GETINFO replies should be empty.
- Add a QUIT command for the controller (for using it manually).
- Fix a bug in SAVECONF that was adding default dirservers and
other redundant entries to the torrc file.
o Start on the new directory design:
- Generate, publish, cache, serve new network-status format.
- Publish individual descriptors (by fingerprint, by "all", and by
"tell me yours").
- Publish client and server recommended versions separately.
- Allow tor_gzip_uncompress() to handle multiple concatenated
compressed strings. Serve compressed groups of router
descriptors. The compression logic here could be more
memory-efficient.
- Distinguish v1 authorities (all currently trusted directories)
from v2 authorities (all trusted directories).
- Change DirServers config line to note which dirs are v1 authorities.
- Add configuration option "V1AuthoritativeDirectory 1" which
moria1, moria2, and tor26 should set.
- Remove option when getting directory cache to see whether they
support running-routers; they all do now. Replace it with one
to see whether caches support v2 stuff.
o New features:
- Dirservers now do their own external reachability testing of each
Tor server, and only list them as running if they've been found to
be reachable. We also send back warnings to the server's logs if
it uploads a descriptor that we already believe is unreachable.
- Implement exit enclaves: if we know an IP address for the
destination, and there's a running Tor server at that address
which allows exit to the destination, then extend the circuit to
that exit first. This provides end-to-end encryption and end-to-end
authentication. Also, if the user wants a .exit address or enclave,
use 4 hops rather than 3, and cannibalize a general circ for it
if you can.
- Permit transitioning from ORPort=0 to ORPort!=0, and back, from the
controller. Also, rotate dns and cpu workers if the controller
changes options that will affect them; and initialize the dns
worker cache tree whether or not we start out as a server.
- Only upload a new server descriptor when options change, 18
hours have passed, uptime is reset, or bandwidth changes a lot.
- Check [X-]Forwarded-For headers in HTTP requests when generating
log messages. This lets people run dirservers (and caches) behind
Apache but still know which IP addresses are causing warnings.
o Config option changes:
- Replace (Fascist)Firewall* config options with a new
ReachableAddresses option that understands address policies.
For example, "ReachableAddresses *:80,*:443"
- Get rid of IgnoreVersion undocumented config option, and make us
only warn, never exit, when we're running an obsolete version.
- Make MonthlyAccountingStart config option truly obsolete now.
o Fixes on 0.1.0.x:
- Reject ports 465 and 587 in the default exit policy, since
people have started using them for spam too.
- It turns out we couldn't bootstrap a network since we added
reachability detection in 0.1.0.1-rc. Good thing the Tor network
has never gone down. Add an AssumeReachable config option to let
servers and dirservers bootstrap. When we're trying to build a
high-uptime or high-bandwidth circuit but there aren't enough
suitable servers, try being less picky rather than simply failing.
- Our logic to decide if the OR we connected to was the right guy
was brittle and maybe open to a mitm for unverified routers.
- We weren't cannibalizing circuits correctly for
CIRCUIT_PURPOSE_C_ESTABLISH_REND and
CIRCUIT_PURPOSE_S_ESTABLISH_INTRO, so we were being forced to
build those from scratch. This should make hidden services faster.
- Predict required circuits better, with an eye toward making hidden
services faster on the service end.
- Retry streams if the exit node sends back a 'misc' failure. This
should result in fewer random failures. Also, after failing
from resolve failed or misc, reset the num failures, so we give
it a fair shake next time we try.
- Clean up the rendezvous warn log msgs, and downgrade some to info.
- Reduce severity on logs about dns worker spawning and culling.
- When we're shutting down and we do something like try to post a
server descriptor or rendezvous descriptor, don't complain that
we seem to be unreachable. Of course we are, we're shutting down.
- Add TTLs to RESOLVED, CONNECTED, and END_REASON_EXITPOLICY cells.
We don't use them yet, but maybe one day our DNS resolver will be
able to discover them.
- Make ContactInfo mandatory for authoritative directory servers.
- Require server descriptors to list IPv4 addresses -- hostnames
are no longer allowed. This also fixes some potential security
problems with people providing hostnames as their address and then
preferentially resolving them to partition users.
- Change log line for unreachability to explicitly suggest /etc/hosts
as the culprit. Also make it clearer what IP address and ports we're
testing for reachability.
- Put quotes around user-supplied strings when logging so users are
more likely to realize if they add bad characters (like quotes)
to the torrc.
- Let auth dir servers start without specifying an Address config
option.
- Make unit tests (and other invocations that aren't the real Tor)
run without launching listeners, creating subdirectories, and so on.
Changes in version 0.1.1.5-alpha - 2005-08-08
o Bugfixes included in 0.1.0.14.
o Bugfixes on 0.1.0.x:
- If you write "HiddenServicePort 6667 127.0.0.1 6668" in your
torrc rather than "HiddenServicePort 6667 127.0.0.1:6668",
it would silently using ignore the 6668.

o Bugfixes included in 0.1.0.13.
o Features:
- Improve tor_gettimeofday() granularity on windows.
- Make clients regenerate their keys when their IP address changes.
- Implement some more GETINFO goodness: expose helper nodes, config

Changes in version 0.1.0.13 - 2005-08-04
o Bugfixes on 0.1.0.x:
- Fix a critical bug in the security of our crypto handshakes.
- Fix a size_t underflow in smartlist_join_strings2() that made
it do bad things when you hand it an empty smartlist.
- Fix Windows installer to ship Tor license (thanks to Aphex for
pointing out this oversight) and put a link to the doc directory
in the start menu.

Changes in version 0.1.1.3-alpha - 2005-07-23
o Bugfixes on 0.1.1.2-alpha:
- Fix a bug in handling the controller's "post descriptor"
function.
- Fix several bugs in handling the controller's "extend circuit"
function.
- Fix a bug in handling the controller's "stream status" event.
- Fix an assert failure if we have a controller listening for
circuit events and we go offline.
- Re-allow hidden service descriptors to publish 0 intro points.
- Fix a crash when generating your hidden service descriptor if
you don't have enough intro points already.
o New features on 0.1.1.2-alpha:
- New controller function "getinfo accounting", to ask how
many bytes we've used in this time period.
- Experimental support for helper nodes: a lot of the risk from
a small static adversary comes because users pick new random
nodes every time they rebuild a circuit. Now users will try to
stick to the same small set of entry nodes if they can. Not
enabled by default yet.
o Bugfixes on 0.1.0.12:
- If you're an auth dir server, always publish your dirport,
even if you haven't yet found yourself to be reachable.
- Fix a size_t underflow in smartlist_join_strings2() that made
it do bad things when you hand it an empty smartlist.

o New directory servers:
- tor26 has changed IP address.
o Bugfixes on 0.1.0.x:
- Fix a possible double-free in tor_gzip_uncompress().
- When --disable-threads is set, do not search for or link against
pthreads libraries.
- Don't trigger an assert if an authoritative directory server
claims its dirport is 0.
- Fix bug with removing Tor as an NT service: some people were
getting "The service did not return an error." Thanks to Matt
Edman for the fix.

Changes in version 0.1.1.2-alpha - 2005-07-15
o New directory servers:
- tor26 has changed IP address.
o Bugfixes on 0.1.0.x, crashes/leaks:
- Port the servers-not-obeying-their-exit-policies fix from
0.1.0.11.
- Fix an fd leak in start_daemon().
- On Windows, you can't always reopen a port right after you've
closed it. So change retry_listeners() to only close and re-open
ports that have changed.
- Fix a possible double-free in tor_gzip_uncompress().
o Bugfixes on 0.1.0.x, usability:
- When tor_socketpair() fails in Windows, give a reasonable
Windows-style errno back.
- Let people type "tor --install" as well as "tor -install" when
they
want to make it an NT service.
- NT service patch from Matt Edman to improve error messages.
- When the controller asks for a config option with an abbreviated
name, give the full name in our response.
- Correct the man page entry on TrackHostExitsExpire.
- Looks like we were never delivering deflated (i.e. compressed)
running-routers lists, even when asked. Oops.
- When --disable-threads is set, do not search for or link against
pthreads libraries.
o Bugfixes on 0.1.1.x:
- Fix a seg fault with autodetecting which controller version is
being used.
o Features:
- New hidden service descriptor format: put a version in it, and
let people specify introduction/rendezvous points that aren't
in "the directory" (which is subjective anyway).
- Allow the DEBUG controller event to work again. Mark certain log
entries as "don't tell this to controllers", so we avoid cycles.

Changes in version 0.1.0.11 - 2005-06-30
o Bugfixes on 0.1.0.x:
- Fix major security bug: servers were disregarding their
exit policies if clients behaved unexpectedly.
- Make OS X init script check for missing argument, so we don't
confuse users who invoke it incorrectly.
- Fix a seg fault in "tor --hash-password foo".
- The MAPADDRESS control command was broken.

Changes in version 0.1.1.1-alpha - 2005-06-29
o Bugfixes:
- Make OS X init script check for missing argument, so we don't
confuse users who invoke it incorrectly.
- Fix a seg fault in "tor --hash-password foo".
- Fix a possible way to DoS dirservers.
- When we complain that your exit policy implicitly allows local or
private address spaces, name them explicitly so operators can
fix it.
- Make the log message less scary when all the dirservers are
temporarily unreachable.
- We were printing the number of idle dns workers incorrectly when
culling them.
o Features:
- Revised controller protocol (version 1) that uses ascii rather
than binary. Add supporting libraries in python and java so you
can use the controller from your applications without caring how
our protocol works.
- Spiffy new support for crypto hardware accelerators. Can somebody
test this?

Changes in version 0.1.0.9-rc - 2005-06-09
o Bugfixes:
- Reset buf->highwater every time buf_shrink() is called, not just on
a successful shrink. This was causing significant memory bloat.
- Fix buffer overflow when checking hashed passwords.
- Security fix: if seeding the RNG on Win32 fails, quit.
- Allow seeding the RNG on Win32 even when you're not running as
Administrator.
- Disable threading on Solaris too. Something is wonky with it,
cpuworkers, and reentrant libs.
integrate the 0.1.0.9-rc changelog into the 0.1.0.10 changelog svn:r4421
2005-06-13 03:29:35 +02:00
- Reenable the part of the code that tries to flush as soon as an
OR outbuf has a full TLS record available. Perhaps this will make
OR outbufs not grow as huge except in rare cases, thus saving lots
of CPU time plus memory.
- Reject malformed .onion addresses rather then passing them on as
normal web requests.
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
- Adapt patch from Adam Langley: fix possible memory leak in
tor_lookup_hostname().
- Initialize libevent later in the startup process, so the logs are
already established by the time we start logging libevent warns.
- Use correct errno on win32 if libevent fails.
- Check and warn about known-bad/slow libevent versions.
- Pay more attention to the ClientOnly config option.
- Have torctl.in/tor.sh.in check for location of su binary (needed
on FreeBSD)
- Correct/add man page entries for LongLivedPorts, ExitPolicy,
KeepalivePeriod, ClientOnly, NoPublish, HttpProxy, HttpsProxy,
HttpProxyAuthenticator
- Stop warning about sigpipes in the logs. We're going to
pretend that getting these occassionally is normal and fine.
- Resolve OS X installer bugs: stop claiming to be 0.0.9.2 in
certain
installer screens; and don't put stuff into StartupItems unless
the user asks you to.
- Require servers that use the default dirservers to have public IP
addresses. We have too many servers that are configured with private
IPs and their admins never notice the log entries complaining that
their descriptors are being rejected.
- Add OSX uninstall instructions. An actual uninstall script will
come later.
a changelog for 0.1.0.5-rc svn:r4134
2005-04-27 06:36:32 +02:00
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
Changes in version 0.1.0.8-rc - 2005-05-23
o Bugfixes:
- It turns out that kqueue on OS X 10.3.9 was causing kernel
panics. Disable kqueue on all OS X Tors.
- Fix RPM: remove duplicate line accidentally added to the rpm
spec file.
- Disable threads on openbsd too, since its gethostaddr is not
reentrant either.
- Tolerate libevent 0.8 since it still works, even though it's
ancient.
- Enable building on Red Hat 9.0 again.
- Allow the middle hop of the testing circuit to be running any
version, now that most of them have the bugfix to let them connect
to unknown servers. This will allow reachability testing to work
even when 0.0.9.7-0.0.9.9 become obsolete.
- Handle relay cells with rh.length too large. This prevents
a potential attack that could read arbitrary memory (maybe even
keys) from the exit server's process.
- We screwed up the dirport reachability testing when we don't yet
have a cached version of the directory. Hopefully now fixed.
- Clean up router_load_single_router() (used by the controller),
so it doesn't seg fault on error.
- Fix a minor memory leak when somebody establishes an introduction
point at your Tor server.
- If a socks connection ends because read fails, don't warn that
you're not sending a socks reply back.
o Features:
- Add HttpProxyAuthenticator config option too, that works like
the HttpsProxyAuthenticator config option.
forward-port the 0.1.0.9 changelog svn:r4365
2005-06-09 06:06:52 +02:00
- Encode hashed controller passwords in hex instead of base64,
to make it easier to write controllers.
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
Changes in version 0.1.0.7-rc - 2005-05-17
o Bugfixes:
- Fix a bug in the OS X package installer that prevented it from
installing on Tiger.
- Fix a script bug in the OS X package installer that made it
complain during installation.
- Find libevent even if it's hiding in /usr/local/ and your
CFLAGS and LDFLAGS don't tell you to look there.
- Be able to link with libevent as a shared library (the default
after 1.0d), even if it's hiding in /usr/local/lib and even
if you haven't added /usr/local/lib to your /etc/ld.so.conf,
assuming you're running gcc. Otherwise fail and give a useful
error message.
- Fix a bug in the RPM packager: set home directory for _tor to
something more reasonable when first installing.
- Free a minor amount of memory that is still reachable on exit.
Changes in version 0.1.0.6-rc - 2005-05-14
o Bugfixes:
- Implement --disable-threads configure option. Disable threads on
netbsd by default, because it appears to have no reentrant resolver
functions.
- Apple's OS X 10.4.0 ships with a broken kqueue. The new libevent
release (1.1) detects and disables kqueue if it's broken.
- Append default exit policy before checking for implicit internal
addresses. Now we don't log a bunch of complaints on startup
when using the default exit policy.
forward-port the 0.1.0.9 changelog svn:r4365
2005-06-09 06:06:52 +02:00
- Some people were putting "Address " in their torrc, and they had
a buggy resolver that resolved " " to 0.0.0.0. Oops.
- If DataDir is ~/.tor, and that expands to /.tor, then default to
LOCALSTATEDIR/tor instead.
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
- Fix fragmented-message bug in TorControl.py.
- Resolve a minor bug which would prevent unreachable dirports
from getting suppressed in the published descriptor.
- When the controller gave us a new descriptor, we weren't resolving
it immediately, so Tor would think its address was 0.0.0.0 until
we fetched a new directory.
- Fix an uppercase/lowercase case error in suppressing a bogus
libevent warning on some Linuxes.
o Features:
- Begin scrubbing sensitive strings from logs by default. Turn off
the config option SafeLogging if you need to do debugging.
- Switch to a new buffer management algorithm, which tries to avoid
reallocing and copying quite as much. In first tests it looks like
it uses *more* memory on average, but less cpu.
- First cut at support for "create-fast" cells. Clients can use
these when extending to their first hop, since the TLS already
provides forward secrecy and authentication. Not enabled on
clients yet.
- When dirservers refuse a router descriptor, we now log its
contactinfo, platform, and the poster's IP address.
- Call tor_free_all instead of connections_free_all after forking, to
save memory on systems that need to fork.
- Whine at you if you're a server and you don't set your contactinfo.
forward-port the 0.1.0.9 changelog svn:r4365
2005-06-09 06:06:52 +02:00
- Implement --verify-config command-line option to check if your torrc
is valid without actually launching Tor.
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
- Rewrite address "serifos.exit" to "localhost.serifos.exit"
rather than just rejecting it.

0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
Changes in version 0.1.0.5-rc - 2005-04-27
o Bugfixes:
- Stop trying to print a null pointer if an OR conn fails because
we didn't like its cert.
o Features:
- Switch our internal buffers implementation to use a ring buffer,
to hopefully improve performance for fast servers a lot.
- Add HttpsProxyAuthenticator support (basic auth only), based
on patch from Adam Langley.
- Bump the default BandwidthRate from 1 MB to 2 MB, to accommodate
the fast servers that have been joining lately.
- Give hidden service accesses extra time on the first attempt,
since 60 seconds is often only barely enough. This might improve
robustness more.
- Improve performance for dirservers: stop re-parsing the whole
directory every time you regenerate it.
- Add more debugging info to help us find the weird dns freebsd
pthreads bug; cleaner debug messages to help track future issues.
Changes in version 0.0.9.9 - 2005-04-23
o Bugfixes on 0.0.9.x:
- If unofficial Tor clients connect and send weird TLS certs, our
Tor server triggers an assert. This release contains a minimal
backport from the broader fix that we put into 0.1.0.4-rc.
Changes in version 0.1.0.4-rc - 2005-04-23
o Bugfixes:
- If unofficial Tor clients connect and send weird TLS certs, our
Tor server triggers an assert. Stop asserting, and start handling
TLS errors better in other situations too.
- When the controller asks us to tell it about all the debug-level
logs, it turns out we were generating debug-level logs while
telling it about them, which turns into a bad loop. Now keep
track of whether you're sending a debug log to the controller,
and don't log when you are.
- Fix the "postdescriptor" feature of the controller interface: on
non-complete success, only say "done" once.
o Features:
- Clients are now willing to load balance over up to 2mB, not 1mB,
of advertised bandwidth capacity.
- Add a NoPublish config option, so you can be a server (e.g. for
testing running Tor servers in other Tor networks) without
publishing your descriptor to the primary dirservers.
Changes in version 0.1.0.3-rc - 2005-04-08
o Improvements on 0.1.0.2-rc:
- Client now retries when streams end early for 'hibernating' or
'resource limit' reasons, rather than failing them.
- More automated handling for dirserver operators:
- Automatically approve nodes running 0.1.0.2-rc or later,
now that the the reachability detection stuff is working.
- Now we allow two unverified servers with the same nickname
but different keys. But if a nickname is verified, only that
nickname+key are allowed.
- If you're an authdirserver connecting to an address:port,
and it's not the OR you were expecting, forget about that
descriptor. If he *was* the one you were expecting, then forget
about all other descriptors for that address:port.
- Allow servers to publish descriptors from 12 hours in the future.
Corollary: only whine about clock skew from the dirserver if
he's a trusted dirserver (since now even verified servers could
have quite wrong clocks).
- Adjust maximum skew and age for rendezvous descriptors: let skew
be 48 hours rather than 90 minutes.
- Efficiency improvements:
- Keep a big splay tree of (circid,orconn)->circuit mappings to make
it much faster to look up a circuit for each relay cell.
- Remove most calls to assert_all_pending_dns_resolves_ok(),
since they're eating our cpu on exit nodes.
- Stop wasting time doing a case insensitive comparison for every
dns name every time we do any lookup. Canonicalize the names to
lowercase and be done with it.
- Start sending 'truncated' cells back rather than destroy cells,
if the circuit closes in front of you. This means we won't have
to abandon partially built circuits.
- Only warn once per nickname from add_nickname_list_to_smartlist

per failure, so an entrynode or exitnode choice that's down won't
yell so much.
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
- Put a note in the torrc about abuse potential with the default
exit policy.
- Revise control spec and implementation to allow all log messages to
be sent to controller with their severities intact (suggested by
Matt Edman). Update TorControl to handle new log event types.
- Provide better explanation messages when controller's POSTDESCRIPTOR
fails.
- Stop putting nodename in the Platform string in server descriptors.
It doesn't actually help, and it is confusing/upsetting some people.
o Bugfixes on 0.1.0.2-rc:
- We were printing the host mask wrong in exit policies in server
descriptors. This isn't a critical bug though, since we were still
obeying the exit policy internally.
- Fix Tor when compiled with libevent but without pthreads: move
connection_unregister() from _connection_free() to
connection_free().
- Fix an assert trigger (already fixed in 0.0.9.x): when we have
the rare mysterious case of accepting a conn on 0.0.0.0:0, then
when we look through the connection array, we'll find any of the
cpu/dnsworkers. This is no good.
o Bugfixes on 0.0.9.8:
- Fix possible bug on threading platforms (e.g. win32) which was
leaking a file descriptor whenever a cpuworker or dnsworker died.
- When using preferred entry or exit nodes, ignore whether the
circuit wants uptime or capacity. They asked for the nodes, they
get the nodes.
- chdir() to your datadirectory at the *end* of the daemonize process,
not the beginning. This was a problem because the first time you
run tor, if your datadir isn't there, and you have runasdaemon set
to 1, it will try to chdir to it before it tries to create it. Oops.
- Handle changed router status correctly when dirserver reloads
fingerprint file. We used to be dropping all unverified descriptors
right then. The bug was hidden because we would immediately
fetch a directory from another dirserver, which would include the
descriptors we just dropped.

2005-04-08 08:16:38 +02:00
- When we're connecting to an OR and he's got a different nickname/key
than we were expecting, only complain loudly if we're an OP or a
dirserver. Complaining loudly to the OR admins just confuses them.
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
- Tie MAX_DIR_SIZE to MAX_BUF_SIZE, so now directory sizes won't get
artificially capped at 500kB.

Changes in version 0.0.9.8 - 2005-04-07
o Bugfixes on 0.0.9.x:
- We have a bug that I haven't found yet. Sometimes, very rarely,
cpuworkers get stuck in the 'busy' state, even though the cpuworker
thinks of itself as idle. This meant that no new circuits ever got
established. Here's a workaround to kill any cpuworker that's been
busy for more than 100 seconds.
Changes in version 0.1.0.2-rc - 2005-04-01
o Bugfixes on 0.1.0.1-rc:
- Fixes on reachability detection:
- Don't check for reachability while hibernating.
- If ORPort is reachable but DirPort isn't, still publish the
descriptor, but zero out DirPort until it's found reachable.
- When building testing circs for ORPort testing, use only
high-bandwidth nodes, so fewer circuits fail.
- Complain about unreachable ORPort separately from unreachable
DirPort, so the user knows what's going on.
- Make sure we only conclude ORPort reachability if we didn't
initiate the conn. Otherwise we could falsely conclude that
we're reachable just because we connected to the guy earlier
and he used that same pipe to extend to us.
- Authdirservers shouldn't do ORPort reachability detection,
since they're in clique mode, so it will be rare to find a
server not already connected to them.
- When building testing circuits, always pick middle hops running
Tor 0.0.9.7, so we avoid the "can't extend to unknown routers"
bug. (This is a kludge; it will go away when 0.0.9.x becomes
obsolete.)
- When we decide we're reachable, actually publish our descriptor
right then.
- Fix bug in redirectstream in the controller.
- Fix the state descriptor strings so logs don't claim edge streams
are in a different state than they actually are.
- Use recent libevent features when possible (this only really affects
win32 and osx right now, because the new libevent with these
features hasn't been released yet). Add code to suppress spurious
libevent log msgs.
- Prevent possible segfault in connection_close_unattached_ap().
- Fix newlines on torrc in win32.
- Improve error msgs when tor-resolve fails.
o Improvements on 0.0.9.x:
add a changelog for 0.1.0.2-rc svn:r3971
2005-04-01 18:29:52 +02:00
- New experimental script tor/contrib/ExerciseServer.py (needs more
work) that uses the controller interface to build circuits and
fetch pages over them. This will help us bootstrap servers that
have lots of capacity but haven't noticed it yet.
- New experimental script tor/contrib/PathDemo.py (needs more work)
that uses the controller interface to let you choose whole paths
via addresses like
"<hostname>.<path,separated by dots>.<length of path>.path"
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
- When we've connected to an OR and handshaked but didn't like
the result, we were closing the conn without sending destroy
cells back for pending circuits. Now send those destroys.

Changes in version 0.0.9.7 - 2005-04-01
o Bugfixes on 0.0.9.x:
- Fix another race crash bug (thanks to Glenn Fink for reporting).
- Compare identity to identity, not to nickname, when extending to
a router not already in the directory. This was preventing us from
extending to unknown routers. Oops.
- Make sure to create OS X Tor user in <500 range, so we aren't
creating actual system users.
- Note where connection-that-hasn't-sent-end was marked, and fix
a few really loud instances of this harmless bug (it's fixed more
in 0.1.0.x).
Changes in version 0.1.0.1-rc - 2005-03-28
o New features:
- Add reachability testing. Your Tor server will automatically try
to see if its ORPort and DirPort are reachable from the outside,
and it won't upload its descriptor until it decides they are.
- Handle unavailable hidden services better. Handle slow or busy
hidden services better.
- Add support for CONNECTing through https proxies, with "HttpsProxy"
config option.
- New exit policy: accept most low-numbered ports, rather than
rejecting most low-numbered ports.
- More Tor controller support (still experimental). See
http://tor.eff.org/doc/control-spec.txt for all the new features,
including signals to emulate unix signals from any platform;
redirectstream; extendcircuit; mapaddress; getinfo; postdescriptor;
closestream; closecircuit; etc.
- Make nt services work and start on startup on win32 (based on
patch by Matt Edman).
- Add a new AddressMap config directive to rewrite incoming socks
addresses. This lets you, for example, declare an implicit
required exit node for certain sites.
- Add a new TrackHostExits config directive to trigger addressmaps
for certain incoming socks addresses -- for sites that break when
your exit keeps changing (based on patch by Mike Perry).
- Redo the client-side dns cache so it's just an addressmap too.
- Notice when our IP changes, and reset stats/uptime/reachability.
forward-port the 0.1.0.9 changelog svn:r4365
2005-06-09 06:06:52 +02:00
- When an application is using socks5, give him the whole variety of
potential socks5 responses (connect refused, host unreachable, etc),
rather than just "success" or "failure".
- A more sane version numbering system. See
http://tor.eff.org/cvs/tor/doc/version-spec.txt for details.
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
- New contributed script "exitlist": a simple python script to
parse directories and find Tor nodes that exit to listed
addresses/ports.
- New contributed script "privoxy-tor-toggle" to toggle whether
Privoxy uses Tor. Seems to be configured for Debian by default.
- Report HTTP reasons to client when getting a response from directory
servers -- so you can actually know what went wrong.
- New config option MaxAdvertisedBandwidth which lets you advertise
a low bandwidthrate (to not attract as many circuits) while still
allowing a higher bandwidthrate in reality.
o Robustness/stability fixes:
- Make Tor use Niels Provos's libevent instead of its current
poll-but-sometimes-select mess. This will let us use faster async
cores (like epoll, kpoll, and /dev/poll), and hopefully work better
on Windows too.
- pthread support now too. This was forced because when we forked,
we ended up wasting a lot of duplicate ram over time. Also switch
to foo_r versions of some library calls to allow reentry and
threadsafeness.
- Better handling for heterogeneous / unreliable nodes:
- Annotate circuits w/ whether they aim to contain high uptime nodes
and/or high capacity nodes. When building circuits, choose
appropriate nodes.
- This means that every single node in an intro rend circuit,
not just the last one, will have a minimum uptime.
- New config option LongLivedPorts to indicate application streams
that will want high uptime circuits.
- Servers reset uptime when a dir fetch entirely fails. This
hopefully reflects stability of the server's network connectivity.
- If somebody starts his tor server in Jan 2004 and then fixes his
clock, don't make his published uptime be a year.
- Reset published uptime when you wake up from hibernation.
- Introduce a notion of 'internal' circs, which are chosen without
regard to the exit policy of the last hop. Intro and rendezvous
circs must be internal circs, to avoid leaking information. Resolve
and connect streams can use internal circs if they want.
- New circuit pooling algorithm: make sure to have enough circs around
to satisfy any predicted ports, and also make sure to have 2 internal
circs around if we've required internal circs lately (and with high
uptime if we've seen that lately too).
- Split NewCircuitPeriod option into NewCircuitPeriod (30 secs),
which describes how often we retry making new circuits if current
ones are dirty, and MaxCircuitDirtiness (10 mins), which describes
how long we're willing to make use of an already-dirty circuit.
- Cannibalize GENERAL circs to be C_REND, C_INTRO, S_INTRO, and S_REND
circ as necessary, if there are any completed ones lying around
when we try to launch one.
- Make hidden services try to establish a rendezvous for 30 seconds,
rather than for n (where n=3) attempts to build a circuit.
- Change SHUTDOWN_WAIT_LENGTH from a fixed 30 secs to a config option
"ShutdownWaitLength".
- Try to be more zealous about calling connection_edge_end when
things go bad with edge conns in connection.c.
- Revise tor-spec to add more/better stream end reasons.
- Revise all calls to connection_edge_end to avoid sending "misc",
and to take errno into account where possible.
o Bug fixes:
- Fix a race condition that can trigger an assert, when we have a
pending create cell and an OR connection fails right then.
- Fix several double-mark-for-close bugs, e.g. where we were finding
a conn for a cell even if that conn is already marked for close.
- Make sequence of log messages when starting on win32 with no config
file more reasonable.
- When choosing an exit node for a new non-internal circ, don't take
into account whether it'll be useful for any pending x.onion
addresses -- it won't.
- Turn addr_policy_compare from a tristate to a quadstate; this should
help address our "Ah, you allow 1.2.3.4:80. You are a good choice
for google.com" problem.
- Make "platform" string in descriptor more accurate for Win32 servers,
so it's not just "unknown platform".
- Fix an edge case in parsing config options (thanks weasel).
If they say "--" on the commandline, it's not an option.
- Reject odd-looking addresses at the client (e.g. addresses that
contain a colon), rather than having the server drop them because
they're malformed.
- tor-resolve requests were ignoring .exit if there was a working circuit
they could use instead.
- REUSEADDR on normal platforms means you can rebind to the port
right after somebody else has let it go. But REUSEADDR on win32
means to let you bind to the port _even when somebody else
already has it bound_! So, don't do that on Win32.
first cut of a 0.1.0.1-rc1 changelog svn:r3881
2005-03-26 01:46:02 +01:00
- Change version parsing logic: a version is "obsolete" if it is not
recommended and (1) there is a newer recommended version in the
same series, or (2) there are no recommended versions in the same
series, but there are some recommended versions in a newer series.
A version is "new" if it is newer than any recommended version in
the same series.
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
- Stop most cases of hanging up on a socks connection without sending
the socks reject.
o Helpful fixes:
- Require BandwidthRate to be at least 20kB/s for servers.
- When a dirserver causes you to give a warn, mention which dirserver
it was.
- New config option DirAllowPrivateAddresses for authdirservers.
Now by default they refuse router descriptors that have non-IP or
private-IP addresses.
first cut of a 0.1.0.1-rc1 changelog svn:r3881
2005-03-26 01:46:02 +01:00
- Stop publishing socksport in the directory, since it's not
actually meant to be public. For compatibility, publish a 0 there
for now.
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
- Change DirFetchPeriod/StatusFetchPeriod to have a special "Be
smart" value, that is low for servers and high for clients.
- If our clock jumps forward by 100 seconds or more, assume something
has gone wrong with our network and abandon all not-yet-used circs.
- Warn when exit policy implicitly allows local addresses.
- If we get an incredibly skewed timestamp from a dirserver mirror
that isn't a verified OR, don't warn -- it's probably him that's
wrong.

to Brett Carrington for pointing this out.)
0.1.0 in all its detailed glory svn:r9412
2007-01-26 03:08:53 +01:00
- When a client asks us for a dir mirror and we don't have one,
launch an attempt to get a fresh one.
- If we're hibernating and we get a SIGINT, exit immediately.
- Add --with-dmalloc ./configure option, to track memory leaks.
- And try to free all memory on closing, so we can detect what
we're leaking.
- Cache local dns resolves correctly even when they're .exit
addresses.
- Give a better warning when some other server advertises an
ORPort that is actually an apache running ssl.
first cut of a 0.1.0.1-rc1 changelog svn:r3881
2005-03-26 01:46:02 +01:00
- Add "opt hibernating 1" to server descriptor to make it clearer
whether the server is hibernating.
Changes in version 0.0.9.6 - 2005-03-24
o Bugfixes on 0.0.9.x (crashes and asserts):
- Add new end stream reasons to maintainance branch. Fix bug where
reason (8) could trigger an assert. Prevent bug from recurring.
- Apparently win32 stat wants paths to not end with a slash.
- Fix assert triggers in assert_cpath_layer_ok(), where we were
blowing away the circuit that conn->cpath_layer points to, then
checking to see if the circ is well-formed. Backport check to make
sure we dont use the cpath on a closed connection.
- Prevent circuit_resume_edge_reading_helper() from trying to package
inbufs for marked-for-close streams.
- Don't crash on hup if your options->address has become unresolvable.
- Some systems (like OS X) sometimes accept() a connection and tell
you the remote host is 0.0.0.0:0. If this happens, due to some
other mis-features, we get confused; so refuse the conn for now.
o Bugfixes on 0.0.9.x (other):
- Fix harmless but scary "Unrecognized content encoding" warn message.
- Add new stream error reason: TORPROTOCOL reason means "you are not
speaking a version of Tor I understand; say bye-bye to your stream."
- Be willing to cache directories from up to ROUTER_MAX_AGE seconds
into the future, now that we are more tolerant of skew. This
resolves a bug where a Tor server would refuse to cache a directory
because all the directories it gets are too far in the future;
yet the Tor server never logs any complaints about clock skew.
- Mac packaging magic: make man pages useable, and do not overwrite
existing torrc files.
- Make OS X log happily to /var/log/tor/tor.log

o Bugfixes on 0.0.9.x:
- Fix an assert race at exit nodes when resolve requests fail.
- Stop picking unverified dir mirrors--it only leads to misery.
- Patch from Matt Edman to make NT services work better. Service
support is still not compiled into the executable by default.
- Patch from Dmitri Bely so the Tor service runs better under
the win32 SYSTEM account.
- Make tor-resolve actually work (?) on Win32.
- Fix a sign bug when getrlimit claims to have 4+ billion
file descriptors available.
- Stop refusing to start when bandwidthburst == bandwidthrate.
- When create cells have been on the onion queue more than five
seconds, just send back a destroy and take them off the list.

- Don't crash as badly if we have spawned the max allowed number
of dnsworkers, or we're out of file descriptors.
- Block more file-sharing ports in the default exit policy.
forward-port the changelog patch svn:r3550
2005-02-04 03:23:16 +01:00
- MaxConn is now automatically set to the hard limit of max
file descriptors we're allowed (ulimit -n), minus a few for
logs, etc.
- Give a clearer message when servers need to raise their
ulimit -n when they start running out of file descriptors.
forward-port the changelog svn:r3541
2005-02-04 00:55:49 +01:00
- SGI Compatibility patches from Jan Schaumann.
- Tolerate a corrupt cached directory better.
- When a dirserver hasn't approved your server, list which one.
- Go into soft hibernation after 95% of the bandwidth is used,
not 99%. This is especially important for daily hibernators who
have a small accounting max. Hopefully it will result in fewer
cut connections when the hard hibernation starts.
- Load-balance better when using servers that claim more than
800kB/s of capacity.
- Make NT services work (experimental, only used if compiled in).
forward-port the 0.0.9.3 changelog svn:r3414
2005-01-22 08:21:15 +01:00
Changes in version 0.0.9.3 - 2005-01-21
o Bugfixes on 0.0.9:
- Backport the cpu use fixes from main branch, so busy servers won't
need as much processor time.
- Work better when we go offline and then come back, or when we
run Tor at boot before the network is up. We do this by
optimistically trying to fetch a new directory whenever an
application request comes in and we think we're offline -- the
human is hopefully a good measure of when the network is back.
- Backport some minimal hidserv bugfixes: keep rend circuits open as
long as you keep using them; actually publish hidserv descriptors
shortly after they change, rather than waiting 20-40 minutes.
- Enable Mac startup script by default.
- Fix duplicate dns_cancel_pending_resolve reported by Giorgos Pallas.
- When you update AllowUnverifiedNodes or FirewallPorts via the
controller's setconf feature, we were always appending, never
resetting.
- When you update HiddenServiceDir via setconf, it was screwing up
the order of reading the lines, making it fail.
- Do not rewrite a cached directory back to the cache; otherwise we
will think it is recent and not fetch a newer one on startup.
- Workaround for webservers that lie about Content-Encoding: Tor
now tries to autodetect compressed directories and compression
itself. This lets us Proxypass dir fetches through apache.
forward-port the 0.0.9.2 changelog svn:r3287
2005-01-04 10:09:00 +01:00
Changes in version 0.0.9.2 - 2005-01-04
o Bugfixes on 0.0.9 (crashes and asserts):
- Fix an assert on startup when the disk is full and you're logging
to a file.
- If you do socks4 with an IP of 0.0.0.x but *don't* provide a socks4a
style address, then we'd crash.
- Fix an assert trigger when the running-routers string we get from
a dirserver is broken.
- Make worker threads start and run on win32. Now win32 servers
may work better.
- Bandaid (not actually fix, but now it doesn't crash) an assert
where the dns worker dies mysteriously and the main Tor process
doesn't remember anything about the address it was resolving.
o Bugfixes on 0.0.9 (Win32):
- Workaround for brain-damaged __FILE__ handling on MSVC: keep Nick's
name out of the warning/assert messages.
- Fix a superficial "unhandled error on read" bug on win32.
- The win32 installer no longer requires a click-through for our
license, since our Free Software license grants rights but does not
take any away.
- Win32: When connecting to a dirserver fails, try another one
immediately. (This was already working for non-win32 Tors.)
- Stop trying to parse $HOME on win32 when hunting for default
DataDirectory.
- Make tor-resolve.c work on win32 by calling network_init().
o Bugfixes on 0.0.9 (other):
- Make 0.0.9.x build on Solaris again.
- Due to a fencepost error, we were blowing away the \n when reporting
confvalue items in the controller. So asking for multiple config
values at once couldn't work.
- When listing circuits that are pending on an opening OR connection,
if we're an OR we were listing circuits that *end* at us as
being pending on every listener, dns/cpu worker, etc. Stop that.
- Dirservers were failing to create 'running-routers' or 'directory'
strings if we had more than some threshold of routers. Fix them so
they can handle any number of routers.
- Fix a superficial "Duplicate mark for close" bug.
- Stop checking for clock skew for OR connections, even for servers.
- Fix a fencepost error that was chopping off the last letter of any
nickname that is the maximum allowed nickname length.
- Update URLs in log messages so they point to the new website.
- Fix a potential problem in mangling server private keys while
writing to disk (not triggered yet, as far as we know).
- Include the licenses for other free software we include in Tor,
now that we're shipping binary distributions more regularly.

o Bugfixes on 0.0.9rc:
- Fix a stack-trashing crash when an exit node begins hibernating.
- Avoid looking at unallocated memory while considering which
ports we need to build circuits to cover.
- Stop a sigpipe: when an 'end' cell races with eof from the app,
we shouldn't hold-open-until-flush if the eof arrived first.
- Fix a bug with init_cookie_authentication() in the controller.
- When recommending new-format log lines, if the upper bound is
LOG_ERR, leave it implicit.
o Bugfixes on 0.0.8.1:
- Fix a whole slew of memory leaks.
bump to 0.0.9rc7 svn:r3121
2004-12-08 02:14:56 +01:00
- Fix isspace() and friends so they still make Solaris happy
but also so they don't trigger asserts on win32.
a preliminary changelog for rc7 svn:r3119
2004-12-08 00:42:32 +01:00
- Fix parse_iso_time on platforms without strptime (eg win32).
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
- win32: tolerate extra "readable" events better.
a preliminary changelog for rc7 svn:r3119
2004-12-08 00:42:32 +01:00
- win32: when being multithreaded, leave parent fdarray open.
- Make unit tests work on win32.
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
Changes in version 0.0.9rc6 - 2004-12-06
o Bugfixes on 0.0.9pre:
- Clean up some more integer underflow opportunities (not exploitable
we think).
- While hibernating, hup should not regrow our listeners.
- Send an end to the streams we close when we hibernate, rather
than just chopping them off.
- React to eof immediately on non-open edge connections.
o Bugfixes on 0.0.8.1:
bump us to 0.0.9rc6 svn:r3089
2004-12-06 07:27:39 +01:00
- Calculate timeout for waiting for a connected cell from the time
we sent the begin cell, not from the time the stream started. If
it took a long time to establish the circuit, we would time out
right after sending the begin cell.
- Fix router_compare_addr_to_addr_policy: it was not treating a port
of * as always matching, so we were picking reject *:* nodes as
exit nodes too. Oops.
make a changelog for 0.0.9 svn:r3131
2004-12-11 19:07:52 +01:00
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
o Features:
bump us to 0.0.9rc6 svn:r3089
2004-12-06 07:27:39 +01:00
- New circuit building strategy: keep a list of ports that we've
used in the past 6 hours, and always try to have 2 circuits open
or on the way that will handle each such port. Seed us with port
80 so web users won't complain that Tor is "slow to start up".
- Make kill -USR1 dump more useful stats about circuits.
- When warning about retrying or giving up, print the address, so
the user knows which one it's talking about.
- If you haven't used a clean circuit in an hour, throw it away,
just to be on the safe side. (This means after 6 hours a totally
unused Tor client will have no circuits open.)
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
Changes in version 0.0.9rc5 - 2004-12-01
o Bugfixes on 0.0.8.1:
- Disallow NDEBUG. We don't ever want anybody to turn off debug.
- Let resolve conns retry/expire also, rather than sticking around
forever.
- If we are using select, make sure we stay within FD_SETSIZE.
o Bugfixes on 0.0.9pre:
- Fix integer underflow in tor_vsnprintf() that may be exploitable,
but doesn't seem to be currently; thanks to Ilja van Sprundel for
finding it.
- If anybody set DirFetchPostPeriod, give them StatusFetchPeriod
instead. Impose minima and maxima for all *Period options; impose
even tighter maxima for fetching if we are a caching dirserver.
Clip rather than rejecting.
- Fetch cached running-routers from servers that serve it (that is,
authdirservers and servers running 0.0.9rc5-cvs or later.)
o Features:
- Accept *:706 (silc) in default exit policy.
- Implement new versioning format for post 0.1.
a changelog for rc5 svn:r3045
2004-11-30 11:33:23 +01:00
- Support "foo.nickname.exit" addresses, to let Alice request the
address "foo" as viewed by exit node "nickname". Based on a patch
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
by Geoff Goodell.
- Make tor --version --version dump the cvs Id of every file.
Changes in version 0.0.9rc4 - 2004-11-28
o Bugfixes on 0.0.8.1:
- Make windows sockets actually non-blocking (oops), and handle
win32 socket errors better.
add a changelog for rc1 svn:r2950
2004-11-23 08:36:48 +01:00
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
o Bugfixes on 0.0.9rc1:
- Actually catch the -USR2 signal.
Changes in version 0.0.9rc3 - 2004-11-25
o Bugfixes on 0.0.8.1:
- Flush the log file descriptor after we print "Tor opening log file",
so we don't see those messages days later.
o Bugfixes on 0.0.9rc1:
- Make tor-resolve work again.
- Avoid infinite loop in tor-resolve if tor hangs up on it.
- Fix an assert trigger for clients/servers handling resolves.
Changes in version 0.0.9rc2 - 2004-11-24
o Bugfixes on 0.0.9rc1:
- I broke socks5 support while fixing the eof bug.
- Allow unitless bandwidths and intervals; they default to bytes
and seconds.
- New servers don't start out hibernating; they are active until
they run out of bytes, so they have a better estimate of how
long it takes, and so their operators can know they're working.
Changes in version 0.0.9rc1 - 2004-11-23
o Bugfixes on 0.0.8.1:
- Finally fix a bug that's been plaguing us for a year:
With high load, circuit package window was reaching 0. Whenever
we got a circuit-level sendme, we were reading a lot on each
socket, but only writing out a bit. So we would eventually reach
eof. This would be noticed and acted on even when there were still
bytes sitting in the inbuf.
- When poll() is interrupted, we shouldn't believe the revents values.
o Bugfixes on 0.0.9pre6:
- Fix hibernate bug that caused pre6 to be broken.
- Don't keep rephist info for routers that haven't had activity for
24 hours. (This matters now that clients have keys, since we track
them too.)
- Never call close_temp_logs while validating log options.
- Fix backslash-escaping on tor.sh.in and torctl.in.
o Features:
add a changelog for rc1 svn:r2950
2004-11-23 08:36:48 +01:00
- Implement weekly/monthly/daily accounting: now you specify your
hibernation properties by
AccountingMax N bytes|KB|MB|GB|TB
AccountingStart day|week|month [day] HH:MM
Defaults to "month 1 0:00".
- Let bandwidth and interval config options be specified as 5 bytes,
kb, kilobytes, etc; and as seconds, minutes, hours, days, weeks.
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
- kill -USR2 now moves all logs to loglevel debug (kill -HUP to
get back to normal.)
- If your requested entry or exit node has advertised bandwidth 0,
pick it anyway.
- Be more greedy about filling up relay cells -- we try reading again
once we've processed the stuff we read, in case enough has arrived
to fill the last cell completely.
- Apply NT service patch from Osamu Fujino. Still needs more work.
a changelog for 0.0.9pre6 svn:r2900
2004-11-16 04:12:35 +01:00
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
Changes in version 0.0.9pre6 - 2004-11-15
o Bugfixes on 0.0.8.1:
- Fix assert failure on malformed socks4a requests.
- Use identity comparison, not nickname comparison, to choose which
half of circuit-ID-space each side gets to use. This is needed
because sometimes we think of a router as a nickname, and sometimes
as a hex ID, and we can't predict what the other side will do.
- Catch and ignore SIGXFSZ signals when log files exceed 2GB; our
write() call will fail and we handle it there.
- Add a FAST_SMARTLIST define to optionally inline smartlist_get
and smartlist_len, which are two major profiling offenders.
o Bugfixes on 0.0.9pre5:
- Fix a bug in read_all that was corrupting config files on windows.
- When we're raising the max number of open file descriptors to
'unlimited', don't log that we just raised it to '-1'.
- Include event code with events, as required by control-spec.txt.
- Don't give a fingerprint when clients do --list-fingerprint:
it's misleading, because it will never be the same again.
- Stop using strlcpy in tor_strndup, since it was slowing us
down a lot.
- Remove warn on startup about missing cached-directory file.
- Make kill -USR1 work again.
- Hibernate if we start tor during the "wait for wakeup-time" phase
of an accounting interval. Log our hibernation plans better.
- Authoritative dirservers now also cache their directory, so they
have it on start-up.
o Features:
- Fetch running-routers; cache running-routers; compress
running-routers; serve compressed running-routers.z
- Add NSI installer script contributed by J Doe.
a changelog for 0.0.9pre6 svn:r2900
2004-11-16 04:12:35 +01:00
- Commit VC6 and VC7 workspace/project files.
- Commit a tor.spec for making RPM files, with help from jbash.
- Add contrib/torctl.in contributed by Glenn Fink.
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
- Implement the control-spec's SAVECONF command, to write your
configuration to torrc.
- Get cookie authentication for the controller closer to working.
- Include control-spec.txt in the tarball.
- When set_conf changes our server descriptor, upload a new copy.
But don't upload it too often if there are frequent changes.
- Document authentication config in man page, and document signals
we catch.
- Clean up confusing parts of man page and torrc.sample.
a changelog for 0.0.9pre6 svn:r2900
2004-11-16 04:12:35 +01:00
- Make expand_filename handle ~ and ~username.
- Use autoconf to enable largefile support where necessary. Use
ftello where available, since ftell can fail at 2GB.
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
- Distinguish between TOR_TLS_CLOSE and TOR_TLS_ERROR, so we can
log more informatively.
- Give a slightly more useful output for "tor -h".
- Refuse application socks connections to port 0.
- Check clock skew for verified servers, but allow unverified
servers and clients to have any clock skew.
- Break DirFetchPostPeriod into:
- DirFetchPeriod for fetching full directory,
- StatusFetchPeriod for fetching running-routers,
- DirPostPeriod for posting server descriptor,
- RendPostPeriod for posting hidden service descriptors.
- Make sure the hidden service descriptors are at a random offset
from each other, to hinder linkability.
Changes in version 0.0.9pre5 - 2004-11-09
o Bugfixes on 0.0.9pre4:
- Fix a seg fault in unit tests (doesn't affect main program).
- Fix an assert bug where a hidden service provider would fail if
the first hop of his rendezvous circuit was down.
- Hidden service operators now correctly handle version 1 style
INTRODUCE1 cells (nobody generates them still, so not a critical
bug).
- If do_hup fails, actually notice.
- Handle more errnos from accept() without closing the listener.
Some OpenBSD machines were closing their listeners because
they ran out of file descriptors.
- Send resolve cells to exit routers that are running a new
enough version of the resolve code to work right.
- Better handling of winsock includes on non-MSV win32 compilers.
- Some people had wrapped their tor client/server in a script
that would restart it whenever it died. This did not play well
with our "shut down if your version is obsolete" code. Now people
don't fetch a new directory if their local cached version is
recent enough.
- Make our autogen.sh work on ksh as well as bash.

0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
o Major Features:
- Hibernation: New config option "AccountingMaxKB" lets you
set how many KBytes per month you want to allow your server to
consume. Rather than spreading those bytes out evenly over the
month, we instead hibernate for some of the month and pop up
at a deterministic time, work until the bytes are consumed, then
hibernate again. Config option "MonthlyAccountingStart" lets you
specify which day of the month your billing cycle starts on.
draft of a 0.0.9pre5 changelog svn:r2739
2004-11-09 09:13:03 +01:00
- Control interface: a separate program can now talk to your
client/server over a socket, and get/set config options, receive
notifications of circuits and streams starting/finishing/dying,
bandwidth used, etc. The next step is to get some GUIs working.
mention doc/control-spec.txt in changelog svn:r2751

Let us know if you want to help out. See doc/control-spec.txt .
draft of a 0.0.9pre5 changelog svn:r2739
2004-11-09 09:13:03 +01:00
- Ship a contrib/tor-control.py as an example script to interact
with the control port.
- "tor --hash-password zzyxz" will output a salted password for
use in authenticating to the control interface.
- New log format in config:
"Log minsev[-maxsev] stdout|stderr|syslog" or
update the 009pre5 changelog with what i actually announced svn:r2843
2004-11-14 05:54:35 +01:00

0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
o Minor Features:
draft of a 0.0.9pre5 changelog svn:r2739
2004-11-09 09:13:03 +01:00
- DirPolicy config option, to let people reject incoming addresses
from their dirserver.
- "tor --list-fingerprint" will list your identity key fingerprint
and then exit.
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
- Add "pass" target for RedirectExit, to make it easier to break
out of a sequence of RedirectExit rules.
- Clients now generate a TLS cert too, in preparation for having
them act more like real nodes.
- Ship src/win32/ in the tarball, so people can use it to build.
- Make old win32 fall back to CWD if SHGetSpecialFolderLocation
is broken.
- New "router-status" line in directory, to better bind each verified
nickname to its identity key.
- Deprecate unofficial config option abbreviations, and abbreviations
not on the command line.
- Add a pure-C tor-resolve implementation.
- Use getrlimit and friends to ensure we can reach MaxConn (currently
1024) file descriptors.
o Code security improvements, inspired by Ilja:
- Replace sprintf with snprintf. (I think they were all safe, but
hey.)
- Replace strcpy/strncpy with strlcpy in more places.
- Avoid strcat; use snprintf or strlcat instead.
- snprintf wrapper with consistent (though not C99) overflow behavior.
Changes in version 0.0.9pre4 - 2004-10-17
o Bugfixes on 0.0.9pre3:
- If the server doesn't specify an exit policy, use the real default
exit policy, not reject *:*.
- Ignore fascistfirewall when uploading/downloading hidden service
descriptors, since we go through Tor for those; and when using
an HttpProxy, since we assume it can reach them all.
- When looking for an authoritative dirserver, use only the ones
configured at boot. Don't bother looking in the directory.
- The rest of the fix for get_default_conf_file() on older win32.
- Make 'Routerfile' config option obsolete.
o Features:
commit a changelog for pre4 svn:r2556
2004-10-17 07:15:46 +02:00
- New 'MyFamily nick1,...' config option for a server to
specify other servers that shouldn't be used in the same circuit
with it. Only believed if nick1 also specifies us.
- New 'NodeFamily nick1,nick2,...' config option for a client to
specify nodes that it doesn't want to use in the same circuit.
- New 'Redirectexit pattern address:port' config option for a
server to redirect exit connections, e.g. to a local squid.
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
Changes in version 0.0.9pre3 - 2004-10-13
o Bugfixes on 0.0.8.1:
- Better torrc example lines for dirbindaddress and orbindaddress.
- Improved bounds checking on parsed ints (e.g. config options and
the ones we find in directories.)
- Better handling of size_t vs int, so we're more robust on 64
bit platforms.
- Fix the rest of the bug where a newly started OR would appear
as unverified even after we've added his fingerprint and hupped
the dirserver.
- Fix a bug from 0.0.7: when read() failed on a stream, we would
close it without sending back an end. So 'connection refused'
would simply be ignored and the user would get no response.
o Bugfixes on 0.0.9pre2:
- Serving the cached-on-disk directory to people is bad. We now
provide no directory until we've fetched a fresh one.
- Workaround for bug on windows where cached-directories get crlf
corruption.
- Make get_default_conf_file() work on older windows too.
- If we write a *:* exit policy line in the descriptor, don't write
any more exit policy lines.
o Features:
- Use only 0.0.9pre1 and later servers for resolve cells.
changelog for 0.0.9pre3 and 0.0.8.1 svn:r2496
2004-10-14 07:31:03 +02:00
- Make the dirservers file obsolete.
- Include a dir-signing-key token in directories to tell the
parsing entity which key is being used to sign.
more useful changelog for pre3 svn:r2513
2004-10-14 12:27:26 +02:00
- Remove the built-in bulky default dirservers string.
- New config option "Dirserver %s:%d [fingerprint]", which can be
repeated as many times as needed. If no dirservers specified,
default to moria1,moria2,tor26.
0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
- Make moria2 advertise a dirport of 80, so people behind firewalls
will be able to get a directory.
- Http proxy support
- Dirservers translate requests for http://%s:%d/x to /x
- You can specify "HttpProxy %s[:%d]" and all dir fetches will
be routed through this host.
- Clients ask for /tor/x rather than /x for new enough dirservers.
This way we can one day coexist peacefully with apache.
- Clients specify a "Host: %s%d" http header, to be compatible
with more proxies, and so running squid on an exit node can work.

o Bugfixes:
update cvs changelog with 0.0.8.1 entry svn:r2501
2004-10-14 08:44:47 +02:00
- Fix a seg fault that can be triggered remotely for Tor
clients/servers with an open dirport.
changelog for 0.0.9pre3 and 0.0.8.1 svn:r2496
2004-10-14 07:31:03 +02:00
- Fix a rare assert trigger, where routerinfos for entries in
our cpath would expire while we're building the path.
- Fix a bug in OutboundBindAddress so it (hopefully) works.
- Fix a rare seg fault for people running hidden services on
intermittent connections.
- Fix a bug in parsing opt keywords with objects.
- Fix a stale pointer assert bug when a stream detaches and
reattaches.
- Fix a string format vulnerability (probably not exploitable)
in reporting stats locally.
- Fix an assert trigger: sometimes launching circuits can fail
immediately, e.g. because too many circuits have failed recently.
update changelog re: weasel's warn svn:r2505
2004-10-14 08:50:57 +02:00

0.0.9 was a fun one. those were the days. svn:r9409
2007-01-26 01:22:33 +01:00
Changes in version 0.0.9pre2 - 2004-10-03
o Bugfixes:
- Make fetching a cached directory work for 64-bit platforms too.
- Make zlib.h a required header, not an optional header.
Changes in version 0.0.9pre1 - 2004-10-01
o Bugfixes:
- Stop using separate defaults for no-config-file and
empty-config-file. Now you have to explicitly turn off SocksPort,
if you don't want it open.
- Fix a bug in OutboundBindAddress so it (hopefully) works.
- Improve man page to mention more of the 0.0.8 features.
- Fix a rare seg fault for people running hidden services on
intermittent connections.
- Change our file IO stuff (especially wrt OpenSSL) so win32 is
happier.
- Fix more dns related bugs: send back resolve_failed and end cells
more reliably when the resolve fails, rather than closing the
circuit and then trying to send the cell. Also attach dummy resolve
connections to a circuit *before* calling dns_resolve(), to fix
a bug where cached answers would never be sent in RESOLVED cells.
- When we run out of disk space, or other log writing error, don't
crash. Just stop logging to that log and continue.
- We were starting to daemonize before we opened our logs, so if
there were any problems opening logs, we would complain to stderr,
which wouldn't work, and then mysteriously exit.
- Fix a rare bug where sometimes a verified OR would connect to us
before he'd uploaded his descriptor, which would cause us to
assign conn->nickname as though he's unverified. Now we look through
the fingerprint list to see if he's there.
- Fix a rare assert trigger, where routerinfos for entries in
our cpath would expire while we're building the path.
o Features:
- Clients can ask dirservers for /dir.z to get a compressed version
of the directory. Only works for servers running 0.0.9, of course.
- Make clients cache directories and use them to seed their router
lists at startup. This means clients have a datadir again.
- Configuration infrastructure support for warning on obsolete
options.
- Respond to content-encoding headers by trying to uncompress as
appropriate.
- Reply with a deflated directory when a client asks for "dir.z".
We could use allow-encodings instead, but allow-encodings isn't
specified in HTTP 1.0.
- Raise the max dns workers from 50 to 100.
- Discourage people from setting their dirfetchpostperiod more often
than once per minute.
- Protect dirservers from overzealous descriptor uploading -- wait
10 seconds after directory gets dirty, before regenerating.

and break out the 0.0.8 changelog too svn:r9408
2007-01-25 23:19:13 +01:00
o Port it to SunOS 5.9 / Athena
Changes in version 0.0.8rc2 - 2004-08-20
o Make it compile on cygwin again.
o When picking unverified routers, skip those with low uptime and/or
low bandwidth, depending on what properties you care about.
Changes in version 0.0.8rc1 - 2004-08-18
o Changes from 0.0.7.3:
- Bugfixes:
- Fix assert triggers: if the other side returns an address 0.0.0.0,
don't put it into the client dns cache.
- If a begin failed due to exit policy, but we believe the IP address
should have been allowed, switch that router to exitpolicy reject *:*
until we get our next directory.
- Features:
- Clients choose nodes proportional to advertised bandwidth.
- Avoid using nodes with low uptime as introduction points.
- Handle servers with dynamic IP addresses: don't replace
options->Address with the resolved one at startup, and
detect our address right before we make a routerinfo each time.
- 'FascistFirewall' option to pick dirservers and ORs on specific
ports; plus 'FirewallPorts' config option to tell FascistFirewall
which ports are open. (Defaults to 80,443)
- Be more aggressive about trying to make circuits when the network
has changed (e.g. when you unsuspend your laptop).
- Check for time skew on http headers; report date in response to
"GET /".
- If the entrynode config line has only one node, don't pick it as
an exitnode.
- Add strict{entry|exit}nodes config options. If set to 1, then
we refuse to build circuits that don't include the specified entry
or exit nodes.
- OutboundBindAddress config option, to bind to a specific
IP address for outgoing connect()s.
- End truncated log entries (e.g. directories) with "[truncated]".
o Patches to 0.0.8preX:
- Bugfixes:
- Patches to compile and run on win32 again (maybe)?
- Fix crash when looking for ~/.torrc with no $HOME set.
- Fix a race bug in the unit tests.
- Handle verified/unverified name collisions better when new
routerinfo's arrive in a directory.
- Sometimes routers were getting entered into the stats before
we'd assigned their identity_digest. Oops.
- Only pick and establish intro points after we've gotten a
directory.
- Features:
- AllowUnverifiedNodes config option to let circuits choose no-name
routers in entry,middle,exit,introduction,rendezvous positions.
Allow middle and rendezvous positions by default.
- Add a man page for tor-resolve.
Changes in version 0.0.7.3 - 2004-08-12
o Stop dnsworkers from triggering an assert failure when you
ask them to resolve the host "".
Changes in version 0.0.8pre3 - 2004-08-09
o Changes from 0.0.7.2:
- Allow multiple ORs with same nickname in routerlist -- now when
people give us one identity key for a nickname, then later
another, we don't constantly complain until the first expires.
- Remember used bandwidth (both in and out), and publish 15-minute
snapshots for the past day into our descriptor.
- You can now fetch $DIRURL/running-routers to get just the
running-routers line, not the whole descriptor list. (But
clients don't use this yet.)
- When people mistakenly use Tor as an http proxy, point them
at the tor-doc.html rather than the INSTALL.
- Remove our mostly unused -- and broken -- hex_encode()
function. Use base16_encode() instead. (Thanks to Timo Lindfors
for pointing out this bug.)
- Rotate onion keys every 12 hours, not every 2 hours, so we have
fewer problems with people using the wrong key.
- Change the default exit policy to reject the default edonkey,
kazaa, gnutella ports.
- Add replace_file() to util.[ch] to handle win32's rename().
o Changes from 0.0.8preX:
- Fix two bugs in saving onion keys to disk when rotating, so
hopefully we'll get fewer people using old onion keys.
- Fix an assert error that was making SocksPolicy not work.
- Be willing to expire routers that have an open dirport -- it's
just the authoritative dirservers we want to not forget.
- Reject tor-resolve requests for .onion addresses early, so we
don't build a whole rendezvous circuit and then fail.
- When you're warning a server that he's unverified, don't cry
wolf unpredictably.
- Fix a race condition: don't try to extend onto a connection
that's still handshaking.
- For servers in clique mode, require the conn to be open before
you'll choose it for your path.
- Fix some cosmetic bugs about duplicate mark-for-close, lack of
end relay cell, etc.
- Measure bandwidth capacity over the last 24 hours, not just 12
- Bugfix: authoritative dirservers were making and signing a new
directory for each client, rather than reusing the cached one.
Changes in version 0.0.8pre2 - 2004-08-04
o Changes from 0.0.7.2:
- Security fixes:
- Check directory signature _before_ you decide whether you're
you're running an obsolete version and should exit.
- Check directory signature _before_ you parse the running-routers
list to decide who's running or verified.
- Bugfixes and features:
- Check return value of fclose while writing to disk, so we don't
end up with broken files when servers run out of disk space.
- Log a warning if the user uses an unsafe socks variant, so people
are more likely to learn about privoxy or socat.
- Dirservers now include RFC1123-style dates in the HTTP headers,
which one day we will use to better detect clock skew.
o Changes from 0.0.8pre1:
- Make it compile without warnings again on win32.
- Log a warning if you're running an unverified server, to let you
know you might want to get it verified.
- Only pick a default nickname if you plan to be a server.
Changes in version 0.0.8pre1 - 2004-07-23
add release notes for 0.0.8pre1 svn:r2118
2004-07-23 02:35:44 +02:00
o Bugfixes:
- Made our unit tests compile again on OpenBSD 3.5, and tor
itself compile again on OpenBSD on a sparc64.
- We were neglecting milliseconds when logging on win32, so
everything appeared to happen at the beginning of each second.
o Protocol changes:
- 'Extend' relay cell payloads now include the digest of the
intended next hop's identity key. Now we can verify that we're
extending to the right router, and also extend to routers we
hadn't heard of before.
o Features:
- Tor nodes can now act as relays (with an advertised ORPort)
without being manually verified by the dirserver operators.
- Uploaded descriptors of unverified routers are now accepted
by the dirservers, and included in the directory.
- Verified routers are listed by nickname in the running-routers
list; unverified routers are listed as "$<fingerprint>".
- We now use hash-of-identity-key in most places rather than
nickname or addr:port, for improved security/flexibility.
and break out the 0.0.8 changelog too svn:r9408
2007-01-25 23:19:13 +01:00
- To avoid Sybil attacks, paths still use only verified servers.
But now we have a chance to play around with hybrid approaches.
- Nodes track bandwidth usage to estimate capacity (not used yet).
add release notes for 0.0.8pre1 svn:r2118
2004-07-23 02:35:44 +02:00
- ClientOnly option for nodes that never want to become servers.
- Directory caching.
- "AuthoritativeDir 1" option for the official dirservers.
- Now other nodes (clients and servers) will cache the latest
directory they've pulled down.
- They can enable their DirPort to serve it to others.
- Clients will pull down a directory from any node with an open
DirPort, and check the signature/timestamp correctly.
- Authoritative dirservers now fetch directories from other
authdirservers, to stay better synced.
- Running-routers list tells who's down also, along with noting
if they're verified (listed by nickname) or unverified (listed
by hash-of-key).
- Allow dirservers to serve running-router list separately.
This isn't used yet.
- ORs connect-on-demand to other ORs
- If you get an extend cell to an OR you're not connected to,
connect, handshake, and forward the create cell.
- The authoritative dirservers stay connected to everybody,
and everybody stays connected to 0.0.7 servers, but otherwise
clients/servers expire unused connections after 5 minutes.
- When servers get a sigint, they delay 30 seconds (refusing new
connections) then exit. A second sigint causes immediate exit.
- File and name management:
- Look for .torrc if no CONFDIR "torrc" is found.
- If no datadir is defined, then choose, make, and secure ~/.tor
as datadir.
- If torrc not found, exitpolicy reject *:*.
- Expands ~/ in filenames to $HOME/ (but doesn't yet expand ~arma).
- If no nickname is defined, derive default from hostname.
- Rename secret key files, e.g. identity.key -> secret_id_key,
to discourage people from mailing their identity key to tor-ops.
- Refuse to build a circuit before the directory has arrived --
it won't work anyway, since you won't know the right onion keys
to use.
and break out the 0.0.8 changelog too svn:r9408
2007-01-25 23:19:13 +01:00
- Try other dirservers immediately if the one you try is down. This
should tolerate down dirservers better now.
add release notes for 0.0.8pre1 svn:r2118
2004-07-23 02:35:44 +02:00
- Parse tor version numbers so we can do an is-newer-than check
rather than an is-in-the-list check.
- New socks command 'resolve', to let us shim gethostbyname()
locally.
- A 'tor_resolve' script to access the socks resolve functionality.
- A new socks-extensions.txt doc file to describe our
interpretation and extensions to the socks protocols.
- Add a ContactInfo option, which gets published in descriptor.
and break out the 0.0.8 changelog too svn:r9408
2007-01-25 23:19:13 +01:00
- Publish OR uptime in descriptor (and thus in directory) too.
add release notes for 0.0.8pre1 svn:r2118
2004-07-23 02:35:44 +02:00
- Write tor version at the top of each log file
- New docs in the tarball:
- tor-doc.html.
- Document that you should proxy your SSL traffic too.

2004-07-08 04:20:25 +02:00
Changes in version 0.0.7.2 - 2004-07-07
o A better fix for the 0.0.0.0 problem, that will hopefully
eliminate the remaining related assertion failures.
add a changelog for 0.0.7.1 svn:r2008
2004-07-04 21:15:11 +02:00
Changes in version 0.0.7.1 - 2004-07-04
o When an address resolves to 0.0.0.0, treat it as a failed resolve,
since internally we use 0.0.0.0 to signify "not yet resolved".

o Updated the man page to reflect the new features.
Changes in version 0.0.7rc2 - 2004-06-06
o Changes from 0.0.7rc1:
- Make it build on Win32 again.
o Changes from 0.0.6.2:
- Rotate dnsworkers and cpuworkers on SIGHUP, so they get new config
settings too.
Changes in version 0.0.7rc1 - 2004-06-02
o Bugfixes:
- On sighup, we were adding another log without removing the first
one. So log messages would get duplicated n times for n sighups.
- Several cases of using a connection after we'd freed it. The
problem was that connections that are pending resolve are in both
the pending_resolve tree, and also the circuit's resolving_streams
list. When you want to remove one, you must remove it from both.
- Fix a double-mark-for-close where an end cell arrived for a
resolving stream, and then the resolve failed.
- Check directory signatures based on name of signer, not on whom
we got the directory from. This will let us cache directories more
easily.
o Features:
- Crank up some of our constants to handle more users.

a changelog for 0.0.7pre1 svn:r1932
2004-06-02 00:42:01 +02:00
o Fixes for crashes and other obnoxious bugs:

2004-05-16 10:50:36 +02:00
- Fix an epipe bug: sometimes when directory connections failed
to connect, we would give them a chance to flush before closing
them.
a changelog for 0.0.7pre1 svn:r1932
2004-06-02 00:42:01 +02:00
- When we detached from a circuit because of resolvefailed, we
would immediately try the same circuit twice more, and then
give up on the resolve thinking we'd tried three different
exit nodes.
- Limit the number of intro circuits we'll attempt to build for a
hidden service per 15-minute period.
- Check recommended-software string *early*, before actually parsing
the directory. Thus we can detect an obsolete version and exit,
even if the new directory format doesn't parse.
o Fixes for security bugs:
- Remember which nodes are dirservers when you startup, and if a
random OR enables his dirport, don't automatically assume he's
a trusted dirserver.
o Other bugfixes:
commit changelog on 0.0.6.2 (about to be released), and notes on 0.0.7pre1 (not yet released) svn:r1872
2004-05-16 10:50:36 +02:00
- Directory connections were asking the wrong poll socket to
start writing, and not asking themselves to start writing.
- When we detached from a circuit because we sent a begin but
didn't get a connected, we would use it again the first time;
but after that we would correctly switch to a different one.
- Stop warning when the first onion decrypt attempt fails; they
will sometimes legitimately fail now that we rotate keys.
interim changelog notes for 0.0.7pre1 svn:r1923
2004-05-28 17:05:48 +02:00
- Override unaligned-access-ok check when $host_cpu is ia64 or
arm. Apparently they allow it but the kernel whines.
- Dirservers try to reconnect periodically too, in case connections
a changelog for 0.0.7pre1 svn:r1932

have failed.
- Fix some memory leaks in directory servers.

- Doxygen markup on all functions and global variables.
interim changelog notes for 0.0.7pre1 svn:r1923
2004-05-28 17:05:48 +02:00
- Make directory functions update routerlist, not replace it. So
a changelog for 0.0.7pre1 svn:r1932
2004-06-02 00:42:01 +02:00
now directory disagreements are not so critical a problem.
interim changelog notes for 0.0.7pre1 svn:r1923
2004-05-28 17:05:48 +02:00
- Remove the upper limit on number of descriptors in a dirserver's
directory (not that we were anywhere close).
- Allow multiple logfiles at different severity ranges.
- Allow *BindAddress to specify ":port" rather than setting *Port
separately. Allow multiple instances of each BindAddress config
option, so you can bind to multiple interfaces if you want.
- Allow multiple exit policy lines, which are processed in order.
Now we don't need that huge line with all the commas in it.
- Enable accept/reject policies on SOCKS connections, so you can bind
to 0.0.0.0 but still control who can use your OP.

o Fix two bugs in our AES counter-mode implementation (this affected
onion-level stream encryption, but not TLS-level). It turns
out we were doing something much more akin to a 16-character
polyalphabetic cipher. Oops.

[version bump only]
Changes in version 0.0.6rc4 - 2004-05-01
o Update the built-in dirservers list to use the new directory format
o Fix a rare seg fault: if a node offering a hidden service attempts
to build a circuit to Alice's rendezvous point and fails before it
reaches the last hop, it retries with a different circuit, but
then dies.
o Handle windows socket errors correctly.
Changes in version 0.0.6rc3 - 2004-04-28
o Don't expire non-general excess circuits (if we had enough
circuits open, we were expiring rendezvous circuits -- even
when they had a stream attached. oops.)
o Fetch randomness from /dev/urandom better (not via fopen/fread)
o Better debugging for tls errors
o Some versions of openssl have an SSL_pending function that erroneously
returns bytes when there is a non-application record pending.
o Set Content-Type on the directory and hidserv descriptor.
o Remove IVs from cipher code, since AES-ctr has none.
o Win32 fixes. Tor now compiles on win32 with no warnings/errors.
o We were using an array of length zero in a few places.
o win32's gethostbyname can't resolve an IP to an IP.
o win32's close can't close a socket.
Changes in version 0.0.6rc2 - 2004-04-26
o Fix a bug where we were closing tls connections intermittently.
It turns out openssl keeps its errors around -- so if an error
happens, and you don't ask about it, and then another openssl
operation happens and succeeds, and you ask if there was an error,
it tells you about the first error. Fun fun.
o Fix a bug that's been lurking since 27 may 03 (!)
When passing back a destroy cell, we would use the wrong circ id.
'Mostly harmless', but still worth fixing.
o Since we don't support truncateds much, don't bother sending them;
just close the circ.
o check for <machine/limits.h> so we build on NetBSD again (I hope).
o don't crash if a conn that sent a begin has suddenly lost its circuit
(this was quite rare).
Changes in version 0.0.6rc1 - 2004-04-25
o We now rotate link (tls context) keys and onion keys.
o CREATE cells now include oaep padding, so you can tell
if you decrypted them correctly.
o Add bandwidthburst to server descriptor.
o Directories now say which dirserver signed them.
o Use a tor_assert macro that logs failed assertions too.
Changes in version 0.0.6pre5 - 2004-04-18
o changes from 0.0.6pre4:
- make tor build on broken freebsd 5.2 installs
- fix a failed assert when you try an intro point, get a nack, and try
a second one and it works.
- when alice uses a port that the hidden service doesn't accept,
it now sends back an end cell (denied by exit policy). otherwise
alice would just have to wait to time out.
- fix another rare bug: when we had tried all the intro
points for a hidden service, we fetched the descriptor
again, but we left our introcirc thinking it had already
sent an intro, so it kept waiting for a response...
- bugfix: when you sleep your hidden-service laptop, as soon
as it wakes up it tries to upload a service descriptor, but
socketpair fails for some reason (localhost not up yet?).
now we simply give up on that upload, and we'll try again later.
i'd still like to find the bug though.
- if an intro circ waiting for an ack dies before getting one, then
count it as a nack
- we were reusing stale service descriptors and refetching usable
ones. oops.
Changes in version 0.0.6pre4 - 2004-04-14
o changes from 0.0.6pre3:
- when bob fails to connect to the rendezvous point, and his
circ didn't fail because of the rendezvous point itself, then
he retries a couple of times
- we expire introduction and rendezvous circs more thoroughly
(sometimes they were hanging around forever)
- we expire unattached rendezvous streams that have been around
too long (they were sticking around forever).
- fix a measly fencepost error that was crashing everybody with
a strict glibc.
Changes in version 0.0.6pre3 - 2004-04-14
o changes from 0.0.6pre2:
- make hup work again
- fix some memory leaks for dirservers
- allow more skew in rendezvous descriptor timestamps, to help
handle people like blanu who don't know what time it is
- normal circs are 3 hops, but some rend/intro circs are 4, if
the initiator doesn't get to choose the last hop
- send acks for introductions, so alice can know whether to try
again
- bob publishes intro points more correctly
o changes from 0.0.5:
- fix an assert trigger that's been plaguing us since the days
of 0.0.2prexx (thanks weasel!)
- retry stream correctly when we fail to connect because of
exit-policy-reject (should try another) or can't-resolve-address
(also should try another, because dns on random internet servers
is flaky).
- when we hup a dirserver and we've *removed* a server from the
approved-routers list, now we remove that server from the
in-memory directories too
Changes in version 0.0.6pre2 - 2004-04-08
o We fixed our base32 implementation. Now it works on all architectures.
Changes in version 0.0.6pre1 - 2004-04-08
commit the 0.0.6 changelog svn:r1769
2004-05-02 21:26:51 +02:00
o Features:
- Hidden services and rendezvous points are implemented. Go to
http://6sxoyfb3h2nvok2d.onion/ for an index of currently available
hidden services. (This only works via a socks4a proxy such as
Privoxy, and currently it's quite slow.)

o Hold socks connection open until reply is flushed (if possible)
o Make exit nodes resolve IPs to IPs immediately, rather than asking
the dns farm to do it.
o Fix c99 aliasing warnings in rephist.c
o Don't include server descriptors that are older than 24 hours in the
directory.
o Give socks 'reject' replies their whole 15s to attempt to flush,
rather than seeing the 60s timeout and assuming the flush had failed.
o Clean automake droppings from the cvs repository
spelunking: break 0.0.5 and 0.0.6 into their actual changelog entries svn:r9406
2007-01-25 22:25:22 +01:00
Changes in version 0.0.5rc1 - 2004-03-28
o Fix mangled-state bug in directory fetching (was causing sigpipes).
o Only build circuits after we've fetched the directory: clients were
using only the directory servers before they'd fetched a directory.
This also means longer startup time; so it goes.
o Fix an assert trigger where an OP would fail to handshake, and we'd
expect it to have a nickname.
o Work around a tsocks bug: do a socks reject when AP connection dies
early, else tsocks goes into an infinite loop.

2004-03-26 19:15:31 +01:00
Changes in version 0.0.3 - 2004-03-26
o Warn and fail if server chose a nickname with illegal characters
o Port to Solaris and Sparc:
- include missing header fcntl.h
- have autoconf find -lsocket -lnsl automatically
- deal with hardware word alignment
- make uname() work (solaris has a different return convention)
- switch from using signal() to sigaction()
o Preliminary work on reputation system:
- Keep statistics on success/fail of connect attempts; they're published
by kill -USR1 currently.
- Add a RunTesting option to try to learn link state by creating test
circuits, even when SocksPort is off.
- Remove unused open circuits when there are too many.

now we allow them if they're set explicitly).
- And fix a few endian issues.
a changelog for pre26 svn:r1274
2004-03-15 02:03:10 +01:00
Changes in version 0.0.2pre26 - 2004-03-14
o New features:
- If a stream times out after 15s without a connected cell, don't
try that circuit again: try a new one.
- Retry streams at most 4 times. Then give up.
- When a dirserver gets a descriptor from an unknown router, it
logs its fingerprint (so the dirserver operator can choose to
accept it even without mail from the server operator).
- Inform unapproved servers when we reject their descriptors.
- Make tor build on Windows again. It works as a client, who knows
about as a server.
- Clearer instructions in the torrc for how to set up a server.
- Be more efficient about reading fd's when our global token bucket
(used for rate limiting) becomes empty.
o Bugfixes:
- Stop asserting that computers always go forward in time. It's
simply not true.
- When we sent a cell (e.g. destroy) and then marked an OR connection
expired, we might close it before finishing a flush if the other
side isn't reading right then.
- Don't allow dirservers to start if they haven't defined
RecommendedVersions
- We were caching transient dns failures. Oops.
- Prevent servers from publishing an internal IP as their address.
- Address a strcat vulnerability in circuit.c

2004-03-04 22:40:38 +01:00
Changes in version 0.0.2pre25 - 2004-03-04
o New features:
- Put the OR's IP in its router descriptor, not its fqdn. That way
we'll stop being stalled by gethostbyname for nodes with flaky dns,
e.g. poblano.
o Bugfixes:
- If the user typed in an address that didn't resolve, the server
crashed.

Changes in version 0.0.2pre24 - 2004-03-03
o Bugfixes:
- Fix an assertion failure in dns.c, where we were trying to dequeue
a pending dns resolve even if it wasn't pending

2004-05-09 18:32:22 +02:00
- Fix a spurious socks5 warning about still trying to write after the
connection is finished.
commit the pre24 changelog svn:r1216
2004-03-03 10:41:13 +01:00
- Hold certain marked_for_close connections open until they're finished
flushing, rather than losing bytes by closing them too early.
- Correctly report the reason for ending a stream
- Remove some duplicate calls to connection_mark_for_close
- Put switch_id and start_daemon earlier in the boot sequence, so it
will actually try to chdir() to options.DataDirectory
- Make 'make test' exit(1) if a test fails; fix some unit tests
- Make tor fail when you use a config option it doesn't know about,
rather than warn and continue.
- Make --version work
- Bugfixes on the rpm spec file and tor.sh, so it's more up to date

2004-02-29 12:13:14 +01:00
Changes in version 0.0.2pre23 - 2004-02-29
o New features:
- Print a statement when the first circ is finished, so the user
knows it's working.
- If a relay cell is unrecognized at the end of the circuit,
send back a destroy. (So attacks to mutate cells are more
clearly thwarted.)
- New config option 'excludenodes' to avoid certain nodes for circuits.
- When it daemonizes, it chdir's to the DataDirectory rather than "/",
so you can collect coredumps there.
o Bugfixes:
- Fix a bug in tls flushing where sometimes data got wedged and
didn't flush until more data got sent. Hopefully this bug was
a big factor in the random delays we were seeing.
- Make 'connected' cells include the resolved IP, so the client
dns cache actually gets populated.
- Disallow changing from ORPort=0 to ORPort>0 on hup.
- When we time-out on a stream and detach from the circuit, send an
end cell down it first.
- Only warn about an unknown router (in exitnodes, entrynodes,
excludenodes) after we've fetched a directory.
changelog entries for pre22 svn:r1135
2004-02-27 01:55:31 +01:00
Changes in version 0.0.2pre22 - 2004-02-26
o New features:
- Servers publish less revealing uname information in descriptors.
- More memory tracking and assertions, to crash more usefully when
errors happen.
- If the default torrc isn't there, just use some default defaults.
Plus provide an internal dirservers file if they don't have one.
- When the user tries to use Tor as an http proxy, give them an http
501 failure explaining that we're a socks proxy.
- Dump a new router.desc on hup, to help confused people who change
their exit policies and then wonder why router.desc doesn't reflect
it.
- Clean up the generic tor.sh init script that we ship with.
o Bugfixes:
- If the exit stream is pending on the resolve, and a destroy arrives,
then the stream wasn't getting removed from the pending list. I
think this was the one causing recent server crashes.
- Use a more robust poll on OSX 10.3, since their poll is flaky.
- When it couldn't resolve any dirservers, it was useless from then on.
Now it reloads the RouterFile (or default dirservers) if it has no
dirservers.
- Move the 'tor' binary back to /usr/local/bin/ -- it turns out
many users don't even *have* a /usr/local/sbin/.

2004-02-18 10:40:18 +01:00
- There's a 'torify' wrapper script, with an accompanying
tor-tsocks.conf, that simplifies the process of using tsocks for
tor. It even has a man page.

his/her torrc.
- Allow imaps and pop3s in default exit policy
o Bugfixes:
- Prevent picking middleman nodes as the last node in the circuit
Put something useful into the ChangeLog, like past release announcments svn:r1061
2004-02-17 01:31:39 +01:00
Changes in version 0.0.2pre20 - 2004-01-30
o New features:
- We now have a deb package, and it's in debian unstable. Go to
it, apt-getters. :)
- I've split the TotalBandwidth option into BandwidthRate (how many
bytes per second you want to allow, long-term) and
BandwidthBurst (how many bytes you will allow at once before the cap
kicks in). This better token bucket approach lets you, say, set
BandwidthRate to 10KB/s and BandwidthBurst to 10MB, allowing good
performance while not exceeding your monthly bandwidth quota.
- Push out a tls record's worth of data once you've got it, rather
than waiting until you've read everything waiting to be read. This
may improve performance by pipelining better. We'll see.
- Add an AP_CONN_STATE_CONNECTING state, to allow streams to detach
from failed circuits (if they haven't been connected yet) and attach
to new ones.
- Expire old streams that haven't managed to connect. Some day we'll
have them reattach to new circuits instead.
o Bugfixes:
- Fix several memory leaks that were causing servers to become bloated
after a while.
- Fix a few very rare assert triggers. A few more remain.
- Setuid to User _before_ complaining about running as root.
Changes in version 0.0.2pre19 - 2004-01-07
o Bugfixes:
- Fix deadlock condition in dns farm. We were telling a child to die by
closing the parent's file descriptor to him. But newer children were
inheriting the open file descriptor from the parent, and since they
weren't closing it, the socket never closed, so the child never read
eof, so he never knew to exit. Similarly, dns workers were holding
open other sockets, leading to all sorts of chaos.
- New cleaner daemon() code for forking and backgrounding.
- If you log to a file, it now prints an entry at the top of the
logfile so you know it's working.
- The onionskin challenge length was 30 bytes longer than necessary.
- Started to patch up the spec so it's not quite so out of date.
Changes in version 0.0.2pre18 - 2004-01-02
o Bugfixes:
- Fix endian issues with the 'integrity' field in the relay header.
- Fix a potential bug where connections in state
AP_CONN_STATE_CIRCUIT_WAIT might unexpectedly ask to write.
Changes in version 0.0.2pre17 - 2003-12-30
o Bugfixes:
- Made --debuglogfile (or any second log file, actually) work.
- Resolved an edge case in get_unique_circ_id_by_conn where a smart
adversary could force us into an infinite loop.
o Features:
- Each onionskin handshake now includes a hash of the computed key,
to prove the server's identity and help perfect forward secrecy.
- Changed cell size from 256 to 512 bytes (working toward compatibility
with MorphMix).
- Changed cell length to 2 bytes, and moved it to the relay header.
- Implemented end-to-end integrity checking for the payloads of
relay cells.
- Separated streamid from 'recognized' (otherwise circuits will get
messed up when we try to have streams exit from the middle). We
use the integrity-checking to confirm that a cell is addressed to
this hop.
- Randomize the initial circid and streamid values, so an adversary who
breaks into a node can't learn how many circuits or streams have
been made so far.
Changes in version 0.0.2pre16 - 2003-12-14
o Bugfixes:
- Fixed a bug that made HUP trigger an assert
- Fixed a bug where a circuit that immediately failed wasn't being
counted as a failed circuit in counting retries.
o Features:
- Now we close the circuit when we get a truncated cell: otherwise we're
open to an anonymity attack where a bad node in the path truncates
the circuit and then we open streams at him.
- Add port ranges to exit policies
- Add a conservative default exit policy
- Warn if you're running tor as root
- on HUP, retry OR connections and close/rebind listeners
- options.EntryNodes: try these nodes first when picking the first node
- options.ExitNodes: if your best choices happen to include any of
your preferred exit nodes, you choose among just those preferred
exit nodes.
- options.ExcludedNodes: nodes that are never picked in path building
Changes in version 0.0.2pre15 - 2003-12-03
o Robustness and bugfixes:
- Sometimes clients would cache incorrect DNS resolves, which would
really screw things up.
- An OP that goes offline would slowly leak all its sockets and stop
working.
- A wide variety of bugfixes in exit node selection, exit policy
handling, and processing pending streams when a new circuit is
established.
- Pick nodes for a path only from those the directory says are up
- Choose randomly from all running dirservers, not always the first one
- Increase allowed http header size for directory fetch.
- Stop writing to stderr (if we're daemonized it will be closed).
- Enable -g always, so cores will be more useful to me.
- Switch "-lcrypto -lssl" to "-lssl -lcrypto" for broken distributions.
o Documentation:
- Wrote a man page. It lists commonly used options.
o Configuration:
- Change default loglevel to warn.
- Make PidFile default to null rather than littering in your CWD.
- OnionRouter config option is now obsolete. Instead it just checks
ORPort>0.
- Moved to a single unified torrc file for both clients and servers.
Changes in version 0.0.2pre14 - 2003-11-29
o Robustness and bugfixes:
- Force the admin to make the DataDirectory himself
- to get ownership/permissions right
- so clients no longer make a DataDirectory and then never use it
- fix bug where a client who was offline for 45 minutes would never
pull down a directory again
- fix (or at least hide really well) the dns assert bug that was
causing server crashes
- warnings and improved robustness wrt clockskew for certs
- use the native daemon(3) to daemonize, when available
- exit if bind() fails
- exit if neither socksport nor orport is defined
- include our own tor_timegm (Win32 doesn't have its own)
- bugfix for win32 with lots of connections
- fix minor bias in PRNG
- make dirserver more robust to corrupt cached directory
o Documentation:
- Wrote the design document (woo)
o Circuit building and exit policies:
- Circuits no longer try to use nodes that the directory has told them
are down.
- Exit policies now support bitmasks (18.0.0.0/255.0.0.0) and
bitcounts (18.0.0.0/8).
- Make AP connections standby for a circuit if no suitable circuit
exists, rather than failing
- Circuits choose exit node based on addr/port, exit policies, and
which AP connections are standing by
- Bump min pathlen from 2 to 3
- Relay end cells have a payload to describe why the stream ended.
- If the stream failed because of exit policy, try again with a new
circuit.
- Clients have a dns cache to remember resolved addresses.
- Notice more quickly when we have no working circuits
o Configuration:
- APPort is now called SocksPort
- SocksBindAddress, ORBindAddress, DirBindAddress let you configure
where to bind
- RecommendedVersions is now a config variable rather than
hardcoded (for dirservers)
- Reloads config on HUP
- Usage info on -h or --help
- If you set User and Group config vars, it'll setu/gid to them.

2004-06-23 22:45:12 +02:00
Changes in version 0.0.2pre13 - 2003-10-19
o General stability:
- SSL_write no longer fails when it returns WANTWRITE and the number
of bytes in the buf has changed by the next SSL_write call.
- Fix segfault fetching directory when network is down
- Fix a variety of minor memory leaks
- Dirservers reload the fingerprints file on HUP, so I don't have
to take down the network when I approve a new router
- Default server config file has explicit Address line to specify fqdn
o Buffers:
- Buffers grow and shrink as needed (Cut process size from 20M to 2M)
- Make listener connections not ever alloc bufs
o Autoconf improvements:
- don't clobber an external CFLAGS in ./configure
- Make install now works
- create var/lib/tor on make install
- autocreate a tor.sh initscript to help distribs
- autocreate the torrc and sample-server-torrc with correct paths
o Log files and Daemonizing now work:
- If --DebugLogFile is specified, log to it at -l debug
- If --LogFile is specified, use it instead of commandline
- If --RunAsDaemon is set, tor forks and backgrounds on startup
