Changes in version 0.3.3.1-alpha - 2018-01-??:
|
||||
Blurb goes here
|
||||
|
||||
o Major feature (channel):
|
||||
- Remove the incoming and outgoing channel queues. The reason to do
|
||||
so was due to the fact that they were always empty meaning never
|
||||
used but still looked at in our fast path. Bottom line, it was an
|
||||
unused code path.
|
||||
- The majority ot the channel unit tests have been rewritten and the
|
||||
code coverage has now been raised to 83.6% for channel.c. Closes
|
||||
ticket 23709.
|
||||
- We've simplify a lot the channel subsystem by removing those
|
||||
queues but also by removing a lot of unused code or dead code
|
||||
around it. Overall this is a cleanup removing more than 1500 lines
|
||||
of code overall and adding very little except for unit test.
|
||||
|
||||
o Major features (embedding):
|
||||
- There is now a documented stable API for programs that need to
|
||||
embed Tor. See tor_api.h for full documentation and known bugs.
|
||||
Closes ticket 23684.
|
||||
- Tor now has support for restarting in the same process.
|
||||
Controllers that run Tor using the "tor_api.h" interface can now
|
||||
restart Tor after Tor has exited. This support is incomplete,
|
||||
however: we have fixed the crash bugs that prevented it from
|
||||
working at all before, but many bugs probably remain, including
|
||||
the possibility of security issues. Implements ticket 24581.
|
||||
|
||||
o Major features (IPv6, directory documents):
|
||||
- Add consensus method 27, which adds IPv6 ORPorts to the microdesc
|
||||
consensus. This makes it easier for IPv6 clients to bootstrap and
|
||||
choose reachable entry guards. Implements 23826.
|
||||
- Add consensus method 28, which removes IPv6 ORPorts from
|
||||
microdescriptors. Now that there are IPv6 ORPorts in the microdesc
|
||||
consensus, they are redundant in microdescs. This change is
|
||||
compatible with tor clients on 0.2.8.x and later. (0.2.8.x
|
||||
introduced client IPv6 bootstrap and guard support.)
|
||||
Implements 23828.
|
||||
- Expand the documentation for AuthDirHasIPv6Connectivity when it is
|
||||
set by different numbers of authorities. Fixes 23870
|
||||
on 0.2.4.1-alpha.
|
||||
|
||||
o Major features (onion service v3, control port):
|
||||
- Control port now supports command and events for v3 onion
|
||||
services. See proposal 284 for more information on what has been
|
||||
done exactly. Only the HSFETCH command hasn't been implemented at
|
||||
this stage because of a lack of use case with v3.
|
||||
|
||||
It is now possible to create ephemeral v3 services using the
|
||||
ADD_ONION command. Additionally, several events (HS_DESC,
|
||||
HS_DESC_CONTENT, CIRC and CIRC_MINOR) and commands (GETINFO,
|
||||
HSPOST, ADD_ONION and DEL_ONION) have been extended to support v3
|
||||
onion services. Closes ticket 20699.
|
||||
|
||||
o Major features (Onion Services):
|
||||
- Provide torrc options to pin the second and third hops of onion
|
||||
service circuits to a list of nodes. The option HSLayer2Guards
|
||||
pins the second hop, and the option HSLayer3Guards pins the third
|
||||
hop. Closes ticket 13837.
|
||||
|
||||
o Major features (relay):
|
||||
- Implement an option, ReducedExitPolicy, to allow an Tor exit relay
|
||||
operator to use a more reasonable ("reduced") exit policy, rather
|
||||
than the default one. Closes ticket 13605. Patch from Neel Chauhan.
|
||||
|
||||
o Major features (Rust experimentation):
|
||||
- Tor now ships with an optional implementation of one of its
|
||||
smaller modules (protover.c) in the Rust programming language. To
|
||||
try it out, install a Rust build environment, and configure Tor
|
||||
with "--enable-rust --enable-cargo-online-mode". This should not
|
||||
cause any user-visible changes, but should help us gain more
|
||||
experience with Rust, and plan future Rust integration work.
|
||||
Implementation by Chelsea Komlo. Closes ticket 22840.
|
||||
|
||||
o Major features (storage):
|
||||
- Users can choose to store cached directory documents somewhere
|
||||
other than the DataDirectory by using the CacheDirectory option.
|
||||
Similarly, the storage location for relay's keys can be overridden
|
||||
with the KeyDirectory option. Closes ticket 22703.
|
||||
|
||||
o Major features (v3 onion services):
|
||||
- When v3 onion service clients send introduce cells, include the
|
||||
IPv6 address of the rendezvous point, if it has one. v3 onion
|
||||
services running 0.3.2 ignore IPv6 addresses. In future Tor
|
||||
versions, IPv6-only v3 single onion services can use IPv6
|
||||
addresses to connect directly to the rendezvous point. Closes
|
||||
ticket 23577. Patch by Neel Chauhan.
|
||||
|
||||
o Major bugfixes (onion services):
|
||||
- Fix an "off by 2" error in counting rendezvous failures on the
|
||||
onion service side. While we thought we would stop the rendezvous
|
||||
attempt after one failed circuit, we were actually making three
|
||||
circuit attempts before giving up. Now switch to a default of 2,
|
||||
and allow the consensus parameter "hs_service_max_rdv_failures" to
|
||||
override. Fixes bug 24895; bugfix on 0.0.6.
|
||||
|
||||
o Major bugfixes (relays):
|
||||
- Fix a set of false positives where relays would consider
|
||||
connections to other relays as being client-only connections (and
|
||||
thus e.g. deserving different link padding schemes) if those
|
||||
relays fell out of the consensus briefly. Now we look only at the
|
||||
initial handshake and whether the connection authenticated as a
|
||||
relay. Fixes bug 24898; bugfix on 0.3.1.1-alpha.
|
||||
|
||||
o Major bugfixes (v3 onion services):
|
||||
- New-style (v3) onion services now obey the "max rendezvous circuit
|
||||
attempts" logic. Previously they would make as many rendezvous
|
||||
circuit attempts as they could fit in the MAX_REND_TIMEOUT second
|
||||
window before giving up. Fixes bug 24894; bugfix on 0.3.2.1-alpha.
|
||||
|
||||
o Minor feature (IPv6):
|
||||
- Make IPv6-only clients wait for microdescs for relays, even if we
|
||||
were previously using descriptors (or were using them as a bridge)
|
||||
and have a cached descriptor for them. Implements 23827.
|
||||
- When a consensus has IPv6 ORPorts, make IPv6-only clients use
|
||||
them, rather than waiting to download microdescriptors.
|
||||
Implements 23827.
|
||||
|
||||
o Minor features (API, embedding):
|
||||
- Tor can now start with a preauthenticated control connection
|
||||
created by the process that launched it. This feature is meant for
|
||||
use by programs that want to launch and manage a Tor process
|
||||
without allowing other programs to manage it as well. For more
|
||||
information, see the __OwningControllerFD option documented in
|
||||
control-spec.txt. Closes ticket 23900.
|
||||
|
||||
o Minor features (cleanup):
|
||||
- Tor now deletes the CookieAuthFile and ExtORPortCookieAuthFile
|
||||
when it stops. Closes ticket 23271.
|
||||
|
||||
o Minor features (code correctness, descriptors):
|
||||
- Check that microdesc ed25519 ids are non-zero in
|
||||
node_get_ed25519_id(), before returning them. Implements 24001,
|
||||
patch by "aruna1234".
|
||||
|
||||
o Minor features (defensive programming):
|
||||
- Most of the functions in Tor that free objects have been replaced
|
||||
with macros that free the objects and set the corresponding
|
||||
pointers to NULL. This change should help prevent a large class of
|
||||
dangling pointer bugs. Closes ticket 24337.
|
||||
- Where possible, the tor_free() macro now only evaluates its input
|
||||
once. Part of ticket 24337.
|
||||
|
||||
o Minor features (directory authority):
|
||||
- Make the "Exit" flag assignment only depend on whether the exit
|
||||
policy allows connections to ports 80 and 443. Previously relays
|
||||
would get the Exit flag if they allowed connections to one of
|
||||
these ports and also port 6667. Resolves ticket 23637.
|
||||
|
||||
o Minor features (embedding):
|
||||
- On most errors that would cause Tor to exit, it now tries to
|
||||
return from the tor_main() function, rather than calling the
|
||||
system exit() function. Most users won't notice a difference here,
|
||||
but it should make a significant difference on platforms that try
|
||||
to run Tor inside a separate thread: they should now be able to
|
||||
survive Tor's exit conditions rather than having Tor shut down the
|
||||
entire process. Closes ticket 23848.
|
||||
|
||||
o Minor features (embedding, mobile):
|
||||
- Applications that want to embed Tor can now tell Tor not to
|
||||
register any of its own POSIX signal handlers, using the
|
||||
__DisableSignalHandlers option. This option is not meant for
|
||||
general use. Closes ticket 24588.
|
||||
|
||||
o Minor features (fallback directory mirrors):
|
||||
- Add a nickname to each fallback in a C comment. This makes it
|
||||
easier for operators to find their relays, and allows stem to use
|
||||
nicknames to identify fallbacks. Implements ticket 24600.
|
||||
- Add a type and version header to the fallback directory mirror
|
||||
file. Also add a delimiter to the end of each fallback entry. This
|
||||
helps external parsers like stem and Relay Search. Implements
|
||||
ticket 24725.
|
||||
- Add an extrainfo cache flag for each fallback in a C comment. This
|
||||
allows stem to use fallbacks to fetch extra-info documents, rather
|
||||
than using authorities. Implements ticket 22759.
|
||||
- Add the generateFallbackDirLine.py script for automatically
|
||||
generating fallback directory mirror lines from relay fingerprints.
|
||||
No more typos! Add the lookupFallbackDirContact.py script for
|
||||
automatically looking up operator contact info from relay
|
||||
fingerprints. Implements ticket 24706, patch by teor and atagar.
|
||||
- Reject any fallback directory mirror that serves an expired
|
||||
consensus. Implements ticket 20942, patch by "minik".
|
||||
- Remove commas and equals signs from external string inputs to the
|
||||
fallback list. This avoids format confusion attacks. Implements
|
||||
ticket 24726.
|
||||
- Remove the "weight=10" line from fallback directory mirror
|
||||
entries. Ticket 24681 will maintain the current fallback weights
|
||||
by changing Tor's default fallback weight to 10. Implements
|
||||
ticket 24679.
|
||||
|
||||
o Minor features (fallbacks):
|
||||
- Avoid selecting fallbacks that change their IP addresses too
|
||||
often. Select more fallbacks by ignoring the Guard flag, and
|
||||
allowing lower cutoffs for the Running and V2Dir flags. Also allow
|
||||
a lower bandwidth, and a higher number of fallbacks per operator
|
||||
(5% of the list). Implements ticket 24785.
|
||||
- Update the fallback whitelist and blacklist based on opt-ins and
|
||||
relay changes. Closes tickets 22321, 24678, 22527, 24135,
|
||||
and 24695.
|
||||
|
||||
o Minor features (forward-compatibility):
|
||||
- If a relay supports some link authentication protocol that we do
|
||||
not recognize, then include that relay's ed25519 key when telling
|
||||
other relays to extend to it. Previously, we treated future
|
||||
versions as if they were too old to support ed25519 link
|
||||
authentication. Closes ticket 20895.
|
||||
|
||||
o Minor features (heartbeat):
|
||||
- Add onion service information to our heartbeat logs, displaying
|
||||
stats about the activity of configured onion services. Closes
|
||||
ticket 24896.
|
||||
|
||||
o Minor features (instrumentation):
|
||||
- Add the MainloopStats option to Tor that allows developers to get
|
||||
instrumentation information from the main event loop via the
|
||||
heartbeat messages. Closes ticket 24605.
|
||||
|
||||
o Minor features (logging):
|
||||
- Improve a warning message that happens when we fail to re-parse an
|
||||
old router because of an expired certificate. Closes ticket 20020.
|
||||
- Make the log more quantitative when we hit MaxMemInQueues
|
||||
threshold exposing some values. Closes ticket 24501.
|
||||
|
||||
o Minor features (logging, android):
|
||||
- Added support for the Android logging subsystem. Closes
|
||||
ticket 24362.
|
||||
|
||||
o Minor features (OSX, iOS, performance):
|
||||
- Use the mach_approximate_time() function (when available) to
|
||||
implement coarse monotonic time. Having a coarse time function
|
||||
should avoid a large number of system calls, and improve
|
||||
performance slightly, especially under load. Closes ticket 24427.
|
||||
|
||||
o Minor features (performance):
|
||||
- Support predictive circuit building for onion service circuits
|
||||
with multiple layers of guards. Closes ticket 23101.
|
||||
- Use stdatomic.h where available, rather than mutexes, to implement
|
||||
atomic_counter_t. Closes ticket 23953.
|
||||
|
||||
o Minor features (performance, 32-bit):
|
||||
- Improve performance on 32-bit systems by avoiding 64-bit division
|
||||
to calculate the current timestamp in milliseconds for channel
|
||||
padding computations. Implements ticket 24613.
|
||||
- Improve performance on 32-bit systems by avoiding 64-bit division
|
||||
when timestamping cells and buffer chunks for OOM calculations.
|
||||
Implements ticket 24374.
|
||||
|
||||
o Minor features (performance, windows):
|
||||
- Improve performance on Windows Vista and Windows 7 by adjusting
|
||||
TCP send window size according to the recommendation from
|
||||
SIO_IDEAL_SEND_BACKLOG_QUERY. Closes ticket 22798. Patch
|
||||
from Vort.
|
||||
|
||||
o Minor features (testing, debugging):
|
||||
- For development purposes, Tor now has a mode in which it runs for
|
||||
a few seconds, then stops, and starts again without exiting the
|
||||
process. This mode is meant to help us debug various issues with
|
||||
ticket 23847. To use this feature, compile with
|
||||
--enable-restart-degbugging, and set the TOR_DEBUG_RESTART
|
||||
environment variable. This is expected to crash a lot, and is
|
||||
really meant for developers only. It will likely be removed in a
|
||||
future release. Implements ticket 24583.
|
||||
|
||||
o Minor bugfix (network IPv6 test):
|
||||
- Tor test now checks if "ping -6 ::1" works when the user runs
|
||||
"make test-network-all". Fixes bug 24677; bugfix on 0.2.9.3-alpha.
|
||||
Patch by "ffmancera".
|
||||
|
||||
o Minor bugfixes (build):
|
||||
- Fix output of autoconf checks to display success messages for Rust
|
||||
dependencies and a suitable rustc compiler version. Fixes bug
|
||||
24612; bugfix on 0.3.1.3-alpha.
|
||||
|
||||
o Minor bugfixes (build, rust):
|
||||
- When building with Rust on OSX, link against libresolv, to work
|
||||
around the issue at https://github.com/rust-lang/rust/issues/46797.
|
||||
Fixes bug 24652; bugfix on 0.3.1.1-alpha.
|
||||
- Don't pass the --quiet option to cargo: it seems to suppress some
|
||||
errors, which is not what we want to do when building. Fixes bug
|
||||
24518; bugfix on 0.3.1.7.
|
||||
- Build correctly when building from outside Tor's source tree with
|
||||
the TOR_RUST_DEPENDENCIES option set. Fixes bug 22768; bugfix
|
||||
on 0.3.1.7.
|
||||
|
||||
o Minor bugfixes (code correctness):
|
||||
- Stop invoking undefined behaviour by using tor_free() on an
|
||||
unaligned pointer in get_interface_addresses_ioctl(). This pointer
|
||||
alignment issue exists on x86_64 macOS, but is unlikely to exist
|
||||
elsewhere. Fixes bug 24733; bugfix on 0.3.0.0-alpha-dev; not in
|
||||
any released version of tor.
|
||||
|
||||
o Minor bugfixes (debugging, memory leaks):
|
||||
- Fix a harmless memory leak in tor-resolve. Fixes bug 24582; bugfix
|
||||
on 0.2.1.1-alpha.
|
||||
|
||||
o Minor bugfixes (directory authorities, IPv6):
|
||||
- When creating a routerstatus (vote) from a routerinfo (descriptor),
|
||||
set the IPv6 address to the unspecified IPv6 address, and
|
||||
explicitly initialise the port to zero. Fixes bug 24488; bugfix
|
||||
on 0.2.4.1-alpha.
|
||||
|
||||
o Minor bugfixes (fallback directory mirrors):
|
||||
- Make updateFallbackDirs.py search harder for python. (Some OSs
|
||||
don't put it in /usr/bin.) Fixes bug 24708; bugfix
|
||||
on 0.2.8.1-alpha.
|
||||
|
||||
o Minor bugfixes (hibernation):
|
||||
- When hibernating, close connections normally and allow them to
|
||||
flush. Fixes bug 23571; bugfix on 0.2.4.7-alpha. Also fixes
|
||||
bug 7267.
|
||||
|
||||
o Minor bugfixes (hibernation, bandwidth accounting, shutdown):
|
||||
- Do not attempt to launch self-reachability tests when entering
|
||||
hibernation. Fixes a base of bug 12062; bugfix on 0.0.9pre5.
|
||||
- Resolve several bugs related to descriptor fetching on bridge
|
||||
clients with bandwidth accounting enabled. (This combination is
|
||||
not recommended!) Fixes a case of bug 12062; bugfix
|
||||
on 0.2.0.3-alpha.
|
||||
- When hibernating, do not attempt to launch DNS checks. Fixes a
|
||||
case of bug 12062; bugfix on 0.1.2.2-alpha.
|
||||
- When hibernating, do not try to upload or download descriptors.
|
||||
Fixes a case of bug 12062; bugfix on 0.0.9pre5.
|
||||
|
||||
o Minor bugfixes (IPv6 preferences on bridges):
|
||||
- Tor now always sets IPv6 preferences for bridges, even if there is
|
||||
only router information or router status and warns about them.
|
||||
Fixes bug 24573; bugfix on 0.2.8.2-alpha.
|
||||
- Tor now sets IPv6 address in rs as well as it's set the one in ri.
|
||||
Closes ticket 24572; bugfix on 0.2.4.5-alpha. Patch by "ffmancera".
|
||||
|
||||
o Minor bugfixes (linux seccomp2 sandbox):
|
||||
- When running with the sandbox enabled, reload configuration files
|
||||
correctly even when %include was used. Previously we would crash.
|
||||
Fixes bug 22605; bugfix on 0.3.1. Patch from Daniel Pinto.
|
||||
|
||||
o Minor bugfixes (memory cleanup):
|
||||
- Avoid possible at-exit memory leaks related to use of Libevent's
|
||||
event_base_once() function. (This function tends to leak memory if
|
||||
the event_base is closed before the event fires.) Fixes bug 24584;
|
||||
bugfix on 0.2.8.1-alpha.
|
||||
|
||||
o Minor bugfixes (OSX):
|
||||
- Don't exit the Tor process if setrlimit() fails to change the file
|
||||
limit (which can happen sometimes on some versions of OSX). Fixes
|
||||
bug 21074; bugfix on 0.0.9pre5.
|
||||
|
||||
o Minor bugfixes (performance):
|
||||
- Consider circuits for timeout as soon as they complete a hop. This
|
||||
is more accurate than applying the timeout in
|
||||
circuit_expire_building() because that function is only called
|
||||
once per second, which is now too slow for typical timeouts on the
|
||||
current network. Fixes bug 23114; bugfix on 0.2.2.2-alpha.
|
||||
- Use onion service circuits (and other circuits longer than 3 hops)
|
||||
to calculate a circuit build timeout. Previously, Tor only
|
||||
calculated its build timeout based on circuits that planned to be
|
||||
exactly 3 hops long. With this change, we include measurements
|
||||
from all circuits at the point where they complete their third
|
||||
hop. Fixes bug 23100; bugfix on 0.2.2.2-alpha.
|
||||
|
||||
o Minor bugfixes (performance, fragile-hardening):
|
||||
- Improve the performance of our consensus-diff application code
|
||||
when Tor is built with the --enable-fragile-hardening option set.
|
||||
Fixes bug 24826; bugfix on 0.3.1.1-alpha.
|
||||
|
||||
o Minor bugfixes (testing):
|
||||
- Give out Exit flags in bootstrapping networks. Fixes bug 24137;
|
||||
bugfix on 0.2.3.1-alpha.
|
||||
- Fix a memory leak in the scheduler/loop_kist unit test. Fixes bug
|
||||
25005; bugfix on 0.3.2.7-rc.
|
||||
|
||||
o Code simplification and refactoring:
|
||||
- Remove /usr/athena from search path in configure.ac. Closes
|
||||
ticket 24363.
|
||||
- Remove duplicate code in node_has_curve25519_onion_key() and
|
||||
node_get_curve25519_onion_key(), and add a check for a zero
|
||||
microdesc curve25519 onion key. Closes ticket 23966, patch by
|
||||
"aruna1234" and "teor".
|
||||
- Rewrite channel_rsa_id_group_set_badness to reduce temporary
|
||||
memory allocations with large numbers of OR connections (e.g.
|
||||
relays). Closes ticket 24119.
|
||||
- Separate the function that deletes ephemeral files when Tor
|
||||
stops gracefully.
|
||||
- Small changes to Tor's buf_t API to make it suitable for use as a
|
||||
general-purpose safe string constructor. Closes ticket 22342.
|
||||
- Switch -Wnormalized=id to -Wnormalized=nfkc in configure.ac to
|
||||
avoid source code identifier confusion. Closes ticket 24467.
|
||||
- The tor_git_revision[] constant no longer needs to be redeclared
|
||||
by everything that links against the rest of Tor. Done as part of
|
||||
ticket 23845, to simplify our external API.
|
||||
- We make extend_info_from_node() use node_get_curve25519_onion_key()
|
||||
introduced in ticket 23577 to access the curve25519 public keys
