Specifically, it was a fix on 33e2053ebc, where we introduced the
WRA_* and ROUTER_* codes for dirserv_add_descriptor. Previously, we
had checked for a _negative_ return from dirserv_add_descriptor, which
meant "rejected". An insufficiently new descriptor would give a
0-valued return. But when we switched from numbers to enums, we got
this check wrong and had init_keys() give an error whenever the
descriptor wasn't accepted.
This mitigates an attack proposed by wanoskarnet, in which all of a
client's bridges collude to restrict the exit nodes that the client
knows about. Fixes bug 5343.
Since 0.2.3.1-alpha, we've supported the Linux extensions to socket(),
open(), socketpair(), and accept() that enable us to create an fd and
make it close-on-exec with a single syscall. This not only saves us a
syscall (big deal), but makes us less vulnerable to race conditions
where we open a socket and then exec before we can make it
close-on-exec.
But these extensions are not supported on all Linuxes: They were added
between 2.6.23 or so and 2.6.28 or so. If you were to build your Tor
against a recent Linux's kernel headers, and then run it with a older
kernel, you would find yourselve unable to open sockets. Ouch!
The solution here is that, when one of these syscalls fails with
EINVAL, we should try again in the portable way. This adds an extra
syscall in the case where we built with new headers and are running
with old ones, but it will at least allow Tor to work.
Fixes bug 5112; bugfix on 0.2.3.1-alpha.
The big change here is a patch (first added to Libevent by Ed Day)
to make sure that the CreateProcess forked-test trick works even
when the main test program is invoked without its .exe suffix.
Previously we'd been using "we have clock_gettime()" as a proxy for
"we need -lrt to link a static libevent". But that's not really
accurate: we should only add -lrt if searching for clock_gettime
function adds -lrt to our libraries.
in Makefile.am, we used it without quoting it, causing build failure if
your openssl/sed/sha1sum happened to live in a directory with a space in
it (very common on windows)
This reverts commit 55e8cae815.
The conversation from irc:
> weasel: i had intended to leave torrc.sample.in alone in maint-0.2.2,
since i don't want to make all your stable users have to deal with
a torrc change. but nickm changed it. is it in fact the case that a
change in that file means a change in the deb?
<weasel> it means you'll prompt every single user who ever touched
their torrc
<weasel> and they will be asked if they like your new version better
than what they have right now
<weasel> so it's not great
Instead I changed the website to redirect requests for the tor-manual
URL listed in maint-0.2.2's torrc.sample.in so the link will still work.
If we don't do this, [::] can be interpreted to mean all v4 and all

There was one MS_WINDOWS that remained because it wasn't on a macro
line; a few remaining uses (and the definition!) in configure.in;
and a now-nonsensical stanza of eventdns_tor.h that previously
defined 'WIN32' if it didn't exist.
Previously the client would ask the bridge for microdescriptors, which are
only supported in 0.2.3.x and later, and then fail to bootstrap when it
didn't get the answers it wanted. Fixes bug 4013; bugfix on 0.2.3.2-alpha.
The fix here is to revert to using normal descriptors if any of our
bridges are known to not support microdescs. This is not ideal, a) because
we'll start downloading a microdesc consensus as soon as we get a bridge
descriptor, and that will waste time if we later get a bridge descriptor
that tells us we don't like microdescriptors; and b) by changing our mind
we're leaking to our other bridges that we have an old-version bridge.
The alternate fix would have been to change
we_use_microdescriptors_for_circuits() to ask if *any* of our bridges
can support microdescriptors, and then change the directory logic that
picks a bridge to only select from those that do. For people living in
the future, where 0.2.2.x is obsolete, there won't be a difference.
Note that in either of these potential fixes, we have risk of oscillation
if our one funny-looking bridges goes away / comes back.
This option seems to be supported all the way back to at least 10.4, so
enabling it for OS X in general should be fine. If not, someone will
yell.
With no libs statically linked, that's a 3% win in binary size, with
just libevent linked statically, this gives us an advantage of 5% in
terms of binary size, and with libevent and openssl statically linked,
we gain over 18% or over 500KB.

These were found by looking for tor_snprintf() instances that were

(To ensure correctness, in every case, make sure that the temporary

To solve bug 4779, we want to avoid OpenSSL 1.0.0's counter mode.
But Fedora (and maybe others) lie about the actual OpenSSL version,
so we can't trust the header to tell us if it's safe.
Instead, let's do a run-time test to see whether it's safe, and if
not, use our built-in version.
fermenthor contributed a pretty essential fixup to this patch. Thanks!

Hostname components cannot be larger than 63 characters.
This simple check makes certain randlen cannot overflow rand_bytes_len.
We used to do this as a workaround for older Tors, but now it's never
the correct thing to do (especially since anything that didn't
understand RELAY_EARLY is now deprecated hard).
This patch should make us reject every Tor that was vulnerable to
CVE-2011-0427. Additionally, it makes us reject every Tor that couldn't
handle RELAY_EARLY cells, which helps with proposal 110 (#4339).
Previously we required 1.0.0, but there was a bug in the 1.0.0 counter
mode. Found by Pascal. Fixes bug 4779.
A more elegant solution would be good here if somebody has time to code

Back in #1240, r1eo linked to information about how this could happen
with older Linux kernels in response to nmap. Bugs #4545 and #4547
are about how our approach to trying to deal with this condition was

This is a fix for the abovementioned bugs, and is a bugfix on
0.1.0.3-rc.
Preprocessor directives should not be put inside the arguments
of a macro. This is not supported on older GCC releases (< 3.3)
thus broke compilation on Haiku (running gcc2).
--enable-gcc-warnings enables two warnings that clang doesn't support,
so the build fails. We had hoped clang 3.0 would add those, but it
didn't, so let's just always disable those warnings when building with
clang. We can still fix it later once they add support
If a relay is dormant at startup, it will call init_keys before
crypto_set_tls_dh_prime. This is bad. Let's make it not so bad, because

This merge just adds the changes file from 0.2.2.
Some controllers want this so they can mess with Tor's configuration
for a while via the control port before actually letting Tor out of
the house.
We do this with a new DisableNetwork option, that prevents Tor from
making any outbound connections or binding any non-control
listeners. Additionally, it shuts down the same functionality as
shuts down when we are hibernating, plus the code that launches
directory downloads.
To make sure I didn't miss anything, I added a clause straight to
connection_connect, so that we won't even try to open an outbound
socket when the network is disabled. In my testing, I made this an
assert, but since I probably missed something, I've turned it into a
BUG warning for testing.
This will mainly help distributors by giving a way to set system or package
defaults that a user can override, and that a later package can replace.
No promises about the particular future location or semantics for this:
we will probably want to tweak it some before 0.2.3.x-rc
The file is searched for in CONFDIR/torrc-defaults , which can be
overridden with the "--defaults-torrc" option on the command line.
This starts an effort to refactor torrc handling code to make it easier
to live with. It makes it possible to override exit policies from the
command line, and possible to override (rather than append to) socksport
lists from the command line.
It'll be necessary to make a "base" torrc implementation work at all.
This shaves about 7% off our per-cell AES crypto time for me; the
effect for accelerated AES crypto should be even more, since the AES
calculation itself will make an even smaller portion of the
counter-mode performance.
(We don't want to do this for pre-1.0.0 OpenSSL, since our AES_CTR
implementation was actually faster than OpenSSL's there, by about
10%.)
Fixes issue #4526.
The timercmp macro uses triggers a "space between function name and
opening parentheses" warning for the check spaces script. Work around
this by simply disabling the check for all "functions" named 'op()'.
The function is over 10 or 20% on some of Moritz's profiles, depending
on how you could.
Since it's checking for a multi-hour timeout, this is safe to do.
Fixes bug 4518.
Completely disable stats if we aren't running as a relay. We won't
collect any anyway, so setting up the infrastructure for them and
logging about them is wrong. This also removes a confusing log
message that clients without a geoip db would have seen.
Fixes bug 4353.
When running with IOCP, we are in theory able to use userspace-
allocated buffers to avoid filling up the stingy amount of kernel
space allocated for sockets buffers.
The bufferevent_async implementation in Libevent provides this
ability, in theory. (There are likely to be remaining bugs). This
patch adds a new option that, when using IOCP bufferevents, sets
each socket's send and receive buffers to 0, so that we should use
this ability.
When all the bugs are worked out here, if we are right about bug 98,
this might solve or mitigate bug 98.
This option is experimental and will likely require lots of testing
and debugging.
This is a fancier bug4457 workaround for 0.2.3. In 0.2.2, we could
just tell Libevent "Don't enable locking!" so it wouldn't try to make
the event_base notifiable. But for IOCP, we need a notifiable base.
(Eventually, we'll want a notifiable base for other stuff, like
multithreaded crypto.) So the solution is to try a full-featured
initialization, and then retry with all the options turned off if that
fails.
Conflicts:
src/common/compat_libevent.c
Resolving conflict by not taking 7363eae13c ("Use the
EVENT_BASE_FLAG_NOLOCK flag to prevent socketpair() invocation"): in
Tor 0.2.3.x, we _do_ sometimes use notifiable event bases.
In Tor 0.2.2, we never need the event base to be notifiable, since we
don't call it from other threads. This is a workaround for bug 4457,
which is not actually a Tor bug IMO.
This thing was pretty pointless on versions of OpenSSL 0.9.8 and later,
and almost totally pointless on OpenSSL 1.0.0.
Also, favor EVP by default, since it lets us get hardware acceleration
where present. (See issue 4442)
The old behavior was susceptible to the compiler optimizing out our
assertion check, *and* could still overflow size_t on 32-bit systems
even when it did work.
- Rename tor_tls_got_server_hello() to tor_tls_got_client_hello().
- Replaced some aggressive asserts with LD_BUG logging.
They were the innocent "I believe I understand how these callbacks
work, and this assert proves it" type of callbacks, and not the "If
this statement is not true, computer is exploding." type of
callbacks.
- Added a changes file.
We would stash the certs in the handshake state before checking them
for validity... and then if they turned out to be invalid, we'd give
an error and free them. Then, later, we'd free them again when we
tore down the connection.
Fixes bug 4343; fix on 0.2.3.6-alpha.
It used to mean "Force": it would tell tor-resolve to ask tor to
resolve an address even if it ended with .onion. But when
AutomapHostsOnResolve was added, automatically refusing to resolve
.onion hosts stopped making sense. So in 0.2.1.16-rc (commit
298dc95dfd), we made tor-resolve happy to resolve anything.
The -F option stayed in, though, even though it didn't do anything.
Oddly, it never got documented.
Found while fixing GCC 4.6 "set, unused variable" warnings.
Previously we did this nearer to the end (in the old_options &&
transition_affects_workers() block). But other stuff cares about

We use a hash of the identity key to seed a prng to tell when an
accounting period should end. But thanks to the bug998 changes,
clients no longer have server-identity keys to use as a long-term seed
in accounting calculations. In any case, their identity keys (as used
in TLS) were never never fixed. So we can just set the wakeup time
from a random seed instead there. Still open is whether everybody
should be random.

From the code:
zlib 1.2.4 and 1.2.5 do some "clever" things with macros. Instead of
saying "(defined(FOO) ? FOO : 0)" they like to say "FOO-0", on the theory
that nobody will care if the compile outputs a no-such-identifier warning.
Sorry, but we like -Werror over here, so I guess we need to define these.
I hope that zlib 1.2.6 doesn't break these too.
Possible fix for bug 1526.

as well as 25, 50, 75 percentile.

intuition on how many descriptors are actually fetched from it and how
many fetches happen in total.

Original message by submitter:
Changing nodes restrictions using a controller while Tor is doing
DNS resolution could makes Tor crashes (on WinXP at least). The
problem can be repeated by trying to reach a non-existent domain
using Tor:
curl --socks4a 127.0.0.1:9050 inexistantdomain.ext
.. and changing the ExitNodes parameter through the control port
before Tor returns a DNS resolution error (of course, the following
command won't work directly if the control port is password
protected):
echo SETCONF ExitNodes=TinyTurtle | nc -v 127.0.0.1 9051
Using a non-existent domain is needed to repeat the issue so that
Tor takes a few seconds for resolving the domain (which allows us to
change the configuration). Tor will crash while processing the
configuration change.
The bug is located in the addressmap_clear_excluded_trackexithosts
method which iterates over the entries of the addresses map in order
to check whether the changes made to the configuration will impact
those entries. When a DNS resolving is in progress, the new_adress
field of the associated entry will be set to NULL. The method
doesn't expect this field to be NULL, hence the crash.
Now let's have "lookup" indicate that there can be a hostname
resolution, and "parse" indicate that there wasn't. Previously, we
had one "lookup" function that did resolution; four "parse" functions,
half of which did resolution; and a "from_str()" function that didn't
do resolution. That's confusing and error-prone!
The code changes in this commit are exactly the result of this perl
script, run under "perl -p -i.bak" :
s/tor_addr_port_parse/tor_addr_port_lookup/g;
s/parse_addr_port(?=[^_])/addr_port_lookup/g;
s/tor_addr_from_str/tor_addr_parse/g;
This patch leaves aton and pton alone: their naming convention and
behavior is is determined by the sockets API.
More renaming may be needed.
Change the default values for collecting directory request statistics and
inlcuding them in extra-info descriptors to 1.
Don't break if we are configured to collect directory request or entry
statistics and don't have a GeoIP database. Instead, print out a notice

This is the cherry-picked 499661524b.
Apparently autoheader throws a tantrum if you say 'AC_DEFINE([a],
[b])'. Instead you must say 'AC_DEFINE([a], [b], [description of
a])'. We were running into this in our replacement definitions for
FLEXIBLE_ARRAY_MEMBER, which were only getting built on autoconf
versions before 2.61 -- and this made us stop working with those
autoconf versinos.
Fixes bug 2430; bugfix on 0.2.3.1-alpha.
Right now we only force a new descriptor upload every 18 hours.
This can make servers become unlisted if they upload a descriptor at
time T which the authorities reject as being "too similar" to one
they uploaded before. Nothing will actually make the server upload a
new descriptor later on, until another 18 hours have passed.
This patch changes the upload behavior so that the 18 hour interval
applies only when we're listed in a live consensus with a descriptor
published within the last 18 hours. Otherwise--if we're not listed
in the live consensus, or if we're listed with a publication time
over 18 hours in the past--we upload a new descriptor every 90
minutes.
This is an attempted bugfix for #3327. If we merge it, it should
obsolete #535.
For some reason, autoconf doesn't by default have an "AC_PROG_AR" for
this -- possibly it's assumed that any "ar" you have will work
everyplace.
Fixes bug 3909; found by sid77.
This fixes a build issue first present in fdbdb4dc15, but the bug
(of not using a correct ar) has been in every Tor version ever: it
just didn't matter until then.
Add a "default" state which we use until we've decided whether we're
live or hibernating. This allows us to properly track whether we're
resuming a hibernation period or not. Fixes bug 2003.
For bufferevents, we had all of connection_buckets_decrement() stubbed
out. But that's not actually right! The rephist_* parts were
essential for, inter alia, recording our own bandwidth. This patch
splits out the rephist parts of connection_buckets_decrement() into their
own function, and makes the bufferevent code call that new function.
Fixes bug 3803, and probably 3824 and 3826 too. Bugfix on 0.2.3.1-alpha.
Previously, if you were set up to use microdescriptors, and you
weren't a cache, you'd never fetch router descriptors (except for
bridges). Now FetchUselessDescriptors causes descriptors and
mirodescs to get cached. Also, FetchUselessDescriptors changes the
behavior of "UseMicrodescriptors auto" to be off, since there's no
point in saying "UseMicrodescriptors 1" when you have full descriptors
too.
Fix for bug 3851; bugfix on 0.2.3.1-alpha.
Because tunneled connections are implemented with buffervent_pair,
writing to them can cause an immediate flush. This means that
added to them and then checking to see whether their outbuf is
empty is _not_ an adequate way to see whether you added anything.
This caused a problem in directory server connections, since they
would try spooling a little more data out, and then close the
connection if there was no queued data to send.
This fix should improve matters; it only closes the connection if
there is no more data to spool, and all of the spooling callbacks
are supposed to put the dirconn into dir_spool_none on completion.
This is bug 3814; Sebastian found it; bugfix on 0.2.3.1-alpha.
When we're doing filtering ssl bufferevents, we want the rate-limits
to apply to the lowest level of the bufferevent stack, so that we're
actually limiting bytes sent on the network. Otherwise, we'll read
from the network aggressively, and only limit stuff as we process it.
Also remove a few other related warnings that could occur during the ssl
handshake. We do this because the relay operator can't do anything about
them, and they aren't their fault.
Starting with Lion, Apple decided to deprecate the system openssl. We
can start requiring users to install their own openssl once OS X doesn't
ship with it anymore.
Right now, we append statistics to files in the stats/ directory for
half of the statistics, whereas we overwrite these files for the other
half. In particular, we append buffer, dirreq, and entry stats and
overwrite exit, connection, and bridge stats.
Appending to files was useful when we didn't include stats in extra-info
descriptors, because otherwise we'd have to copy them away to prevent
Tor from overwriting them.
But now that we include statistics in extra-info descriptors, it makes
no sense to keep the old statistics forever. We should change the
behavior to overwriting instead of appending for all statistics.
Implements #2930.
We'll still need to tweak it so that it looks for includes and
libraries somewhere more sensible than "where we happened to find
them on Erinn's system"; so that tests and tools get built too;
so that it's a bit documented; and so that we actually try running
the output.
Work done with Erinn Clark.
Previously, if tor_addr_to_str() returned NULL, we would reuse the
last value returned by fmt_addr(). (This could happen if we were
erroneously asked to format an AF_UNSPEC address.) Now instead we
return "???".
The problem was that we weren't initializing want_length to 0 before
calling parse_socks() the first time, so it looked like we were
risking an infinite loop when in fact we were safe.
Fixes 3615; bugfix on 0.2.3.2-alpha.
This is the meat of proposal 171: we change circuit_is_acceptable()
to require that the connection is compatible with every connection
that has been linked to the circuit; we update circuit_is_better to
prefer attaching streams to circuits in the way that decreases the
circuits' usefulness the least; and we update link_apconn_to_circ()
to do the appropriate bookkeeping.
Proposal 171 gives us a new syntax for parsing client port options.
You can now have as many FooPort options as you want (for Foo in
Socks, Trans, DNS, NATD), and they can have address:port arguments,
and you can specify the level of isolation on those ports.
Additionally, this patch refactors the client port parsing logic to
use a new type, port_cfg_t. Previously, ports to be bound were
half-parsed in config.c, and later re-parsed in connection.c when
we're about to bind them. Now, parsing a port means converting it
into a port_cfg_t, and binding it uses only a port_cfg_t, without
needing to parse the user-provided strings at all.
We should do a related refactoring on other port types. For
control ports, that'll be easy enough. For ORPort and DirPort,
we'll want to do this when we solve proposal 118 (letting servers
bind to and advertise multiple ports).
This implements tickets 3514 and 3515.
Previously we were using router_get_by_id(foo) to test "do we have a
descriptor that will let us make an anonymous circuit to foo". But
that isn't right for microdescs: we should have been using node_t.
Fixes bug 3601; bugfix on 0.2.3.1-alpha.
Previously, we had an issue where we'd treat an unknown address as
0, which turned into "0.0.0.0", which looked like a rejected
address. This meant in practice that as soon as we started doing
comparisons of unknown uint32 addresses to short policies, we'd get
'rejected' right away. Because of the circumstances under which
this would be called, it would only happen when we had local DNS
cached entries and we were looking to launch new circuits.
Previously, we'd just take all the nodes in EntryNodes, see which
ones were already in the guard list, and add the ones that weren't.
There were some problems there, though:
* We'd add _every_ entry in EntryNodes, and add them in the order
they appeared in the routerlist. This wasn't a problem
until we added the ability to give country-code or IP-range
entries in the EntryNodes set, but now that we did, it is.
(Fix: We now shuffle the entry nodes before adding them; only
add up to 10*NumEntryGuards)
* We didn't screen EntryNodes for the Guard flag. That's okay
if the user has specified two or three entry nodes manually,
but if they have listed a whole subcontinent, we should
restrict ourselves to the entries that are currently guards.
(Fix: separate out the new guard from the new non-guard nodes,
and add the Guards first.)
* We'd prepend new EntryNodes _before_ the already configured
EntryNodes. This could lead to churn.
(Fix: don't prepend these.)
This patch also pre-screens EntryNodes entries for
reachableaddresses/excludenodes, even though we check for that
later. This is important now, since we cap the number of entries
we'll add.
Just looking at the "latest" consensus could give us a microdesc
consensus, if microdescs were enabled. That would make us decide
that every routerdesc was unlisted in the latest consensus and drop
them all: Ouch.
Fixes bug 3113; bugfix on 0.2.3.1-alpha.
The issue was that we overlooked the possibility of reverse DNS success
at the end of connection_ap_handshake_socks_resolved(). Issue discovered
by katmagic, thanks!
Using strncpy meant that if listenaddress were ever >=
sizeof(sockaddr_un.sun_path), we would fail to nul-terminate
sun_path. This isn't a big deal: we never read sun_path, and the
kernel is smart enough to reject the sockaddr_un if it isn't
nul-terminated. Nonetheless, it's a dumb failure mode. Instead, we
should reject addresses that don't fit in sockaddr_un.sun_path.
Coverity found this; it's CID 428. Bugfix on 0.2.0.3-alpha.

Bugfix on 0.2.1.7-alpha. Found by coverity. Fixes CID # 450.
For some inexplicable reason, Coverity departs from its usual
standards of avoiding false positives here, and warns about all

A couple of places in control.c were using connection_handle_write()
to flush important stuff (the response to a SIGNAL command, an
ERR-level status event) before Tor went down. But
connection_handle_write() isn't meaningful for bufferevents, so we'd
crash.
This patch adds a new connection_flush() that works for all connection
backends, and makes control.c use that instead.
Fix for bug 3367; bugfix on 0.2.3.1-alpha.
libnatpmp-20110618 changed the API that tor-fw-helper used and for a time
tor-fw-helper could not build against the newest libnatpmp. This patch brings
support for libnatpmp to tor-fw-helper.
When we set a networkstatus in the non-preferred flavor, we'd check
the time in the current_consensus. But that might have been NULL,
which could produce a crash as seen in bug 3361.
George Kadianakis notes that if you give crypto_rand_int() a value
above INT_MAX, it can return a negative number, which is not what
the documentation would imply.
The simple solution is to assert that the input is in [1,INT_MAX+1].
If in the future we need a random-value function that can return
values up to UINT_MAX, we can add one.
Fixes bug 3306; bugfix on 0.2.2pre14.
When we added the check for key size, we required that the keys be
128 bytes. But RSA_size (which defers to BN_num_bytes) will return
128 for keys of length 1017..1024. This patch adds a new
crypto_pk_num_bits() that returns the actual number of significant
bits in the modulus, and uses that to enforce key sizes.
Also, credit the original bug3318 in the changes file.
This merge was a bit nontrivial, since I had to write a new

When we introduced NEED_KEY_1024 in routerparse.c back in
0.2.0.1-alpha, I forgot to add a *8 when logging the length of a
bad-length key.
Bugfix for 3318 on 0.2.0.1-alpha.
The conflicts were mainly caused by the routerinfo->node transition.
Conflicts:
src/or/circuitbuild.c
src/or/command.c
src/or/connection_edge.c
src/or/directory.c
src/or/dirserv.c
src/or/relay.c
src/or/rendservice.c
src/or/routerlist.c
Previously we did this nearer to the end (in the old_options &&
transition_affects_workers() block). But other stuff cares about
keys being consistent with options... particularly anything which
tries to access a key, which can die in assert_identity_keys_ok().
Fixes bug 3228; bugfix on 0.2.2.18-alpha.
Fixes part of #1297; bugfix on 48e0228f1e,
when circuit_expire_building was changed to assume that timestamp_dirty
was set when a circuit changed purpose to _C_REND_READY. (It wasn't.)
This situation can happen easily if you set 'ORPort auto' and
'AccountingMax'. Doing so means that when you have no ORPort, you
won't be able to set an ORPort in a descriptor, so instead you would
just generate lots of invalid descriptors, freaking out all the time.
Possible fix for 3216; fix on 0.2.2.26-beta.
We had all the code in place to handle this right... except that we
were unconditionally opening a PF_INET socket instead of looking at
sa_family. Ow.
Fixes bug 2574; not a bugfix on any particular version, since this
never worked before.
Most instances were dead code; for those, I removed the assignments.
Some were pieces of info we don't currently plan to use, but which
we might in the future. For those, I added an explicit cast-to-void
to indicate that we know that the thing's unused. Finally, one was
a case where we were testing the wrong variable in a unit test.
That one I fixed.
This resolves bug 3208.
