-Changes in version 0.3.3.6 - 2018-05-22
|
|
|
- Tor 0.3.3.6 is the first stable release in the 0.3.3 series. It
|
|
|
- backports several important fixes from the 0.3.4.1-alpha.
|
|
|
-
|
|
|
- The Tor 0.3.3 series includes controller support and other
|
|
|
- improvements for v3 onion services, official support for embedding Tor
|
|
|
- within other applications, and our first non-trivial module written in
|
|
|
- the Rust programming language. (Rust is still not enabled by default
|
|
|
- when building Tor.) And as usual, there are numerous other smaller
|
|
|
- bugfixes, features, and improvements.
|
|
|
-
|
|
|
- Below are the changes since 0.3.2.10. For a list of only the changes
|
|
|
- since 0.3.3.5-rc, see the ChangeLog file.
|
|
|
-
|
|
|
- o New system requirements:
|
|
|
- - When built with Rust, Tor now depends on version 0.2.39 of the
|
|
|
- libc crate. Closes tickets 25310 and 25664.
|
|
|
-
|
|
|
- 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 fixed crash bugs that prevented it from working at
|
|
|
- all, but many bugs probably remain, including a 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 information makes it easier for IPv6 clients to
|
|
|
- bootstrap and choose reachable entry guards. Implements
|
|
|
- ticket 23826.
|
|
|
- - Add consensus method 28, which removes IPv6 ORPorts from
|
|
|
- microdescriptors. Now that the consensus contains IPv6 ORPorts,
|
|
|
- they are redundant in microdescs. This change will be used by Tor
|
|
|
- clients on 0.2.8.x and later. (That is to say, with all Tor
|
|
|
- clients that have IPv6 bootstrap and guard support.) Implements
|
|
|
- ticket 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):
|
|
|
- - The control port now supports commands and events for v3 onion
|
|
|
- services. It is now possible to create ephemeral v3 services using
|
|
|
- ADD_ONION. 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; implements proposal 284.
|
|
|
-
|
|
|
- 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. These options are for use in conjunction with experiments
|
|
|
- with "vanguards" for preventing guard enumeration attacks. Closes
|
|
|
- ticket 13837.
|
|
|
- - When v3 onion service clients send introduce cells, they now
|
|
|
- include the IPv6 address of the rendezvous point, if it has one.
|
|
|
- Current v3 onion services running 0.3.2 ignore IPv6 addresses, but
|
|
|
- in future Tor versions, IPv6-only v3 single onion services will be
|
|
|
- able to use IPv6 addresses to connect directly to the rendezvous
|
|
|
- point. Closes ticket 23577. Patch by Neel Chauhan.
|
|
|
-
|
|
|
- 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. If you want to run an exit node without
|
|
|
- thinking too hard about which ports to allow, this one is for you.
|
|
|
- Closes ticket 13605. Patch from Neel Chauhan.
|
|
|
-
|
|
|
- o Major features (rust, portability, experimental):
|
|
|
- - 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 bugfixes (directory authorities, security, backport from 0.3.4.1-alpha):
|
|
|
- - When directory authorities read a zero-byte bandwidth file, they
|
|
|
- would previously log a warning with the contents of an
|
|
|
- uninitialised buffer. They now log a warning about the empty file
|
|
|
- instead. Fixes bug 26007; bugfix on 0.2.2.1-alpha.
|
|
|
-
|
|
|
- o Major bugfixes (security, directory authority, denial-of-service):
|
|
|
- - Fix a bug that could have allowed an attacker to force a directory
|
|
|
- authority to use up all its RAM by passing it a maliciously
|
|
|
- crafted protocol versions string. Fixes bug 25517; bugfix on
|
|
|
- 0.2.9.4-alpha. This issue is also tracked as TROVE-2018-005.
|
|
|
-
|
|
|
- o Major bugfixes (crash, backport from 0.3.4.1-alpha):
|
|
|
- - Avoid a rare assertion failure in the circuit build timeout code
|
|
|
- if we fail to allow any circuits to actually complete. Fixes bug
|
|
|
- 25733; bugfix on 0.2.2.2-alpha.
|
|
|
-
|
|
|
- o Major bugfixes (netflow padding):
|
|
|
- - Stop adding unneeded channel padding right after we finish
|
|
|
- flushing to a connection that has been trying to flush for many
|
|
|
- seconds. Instead, treat all partial or complete flushes as
|
|
|
- activity on the channel, which will defer the time until we need
|
|
|
- to add padding. This fix should resolve confusing and scary log
|
|
|
- messages like "Channel padding timeout scheduled 221453ms in the
|
|
|
- past." Fixes bug 22212; bugfix on 0.3.1.1-alpha.
|
|
|
-
|
|
|
- o Major bugfixes (networking):
|
|
|
- - Tor will no longer reject IPv6 address strings from Tor Browser
|
|
|
- when they are passed as hostnames in SOCKS5 requests. Fixes bug
|
|
|
- 25036, bugfix on Tor 0.3.1.2.
|
|
|
-
|
|
|
- o Major bugfixes (onion service, backport from 0.3.4.1-alpha):
|
|
|
- - Correctly detect when onion services get disabled after HUP. Fixes
|
|
|
- bug 25761; bugfix on 0.3.2.1.
|
|
|
-
|
|
|
- o Major bugfixes (performance, load balancing):
|
|
|
- - Directory authorities no longer vote in favor of the Guard flag
|
|
|
- for relays without directory support. Starting in Tor
|
|
|
- 0.3.0.1-alpha, clients have been avoiding using such relays in the
|
|
|
- Guard position, leading to increasingly broken load balancing for
|
|
|
- the 5%-or-so of Guards that don't advertise directory support.
|
|
|
- Fixes bug 22310; bugfix on 0.3.0.6.
|
|
|
-
|
|
|
- o Major bugfixes (relay):
|
|
|
- - If we have failed to connect to a relay and received a connection
|
|
|
- refused, timeout, or similar error (at the TCP level), do not try
|
|
|
- that same address/port again for 60 seconds after the failure has
|
|
|
- occurred. Fixes bug 24767; bugfix on 0.0.6.
|
|
|
-
|
|
|
- o Major bugfixes (relay, denial of service, backport from 0.3.4.1-alpha):
|
|
|
- - Impose a limit on circuit cell queue size. The limit can be
|
|
|
- controlled by a consensus parameter. Fixes bug 25226; bugfix
|
|
|
- on 0.2.4.14-alpha.
|
|
|
-
|
|
|
- o Minor features (cleanup):
|
|
|
- - Tor now deletes the CookieAuthFile and ExtORPortCookieAuthFile
|
|
|
- when it stops. Closes ticket 23271.
|
|
|
-
|
|
|
- o Minor features (compatibility, backport from 0.3.4.1-alpha):
|
|
|
- - Avoid some compilation warnings with recent versions of LibreSSL.
|
|
|
- Closes ticket 26006.
|
|
|
-
|
|
|
- o Minor features (config options):
|
|
|
- - Change the way the default value for MaxMemInQueues is calculated.
|
|
|
- We now use 40% of the hardware RAM if the system has 8 GB RAM or
|
|
|
- more. Otherwise we use the former value of 75%. Closes
|
|
|
- ticket 24782.
|
|
|
-
|
|
|
- o Minor features (continuous integration):
|
|
|
- - Update the Travis CI configuration to use the stable Rust channel,
|
|
|
- now that we have decided to require that. Closes ticket 25714.
|
|
|
-
|
|
|
- o Minor features (continuous integration, backport from 0.3.4.1-alpha):
|
|
|
- - Our .travis.yml configuration now includes support for testing the
|
|
|
- results of "make distcheck". (It's not uncommon for "make check"
|
|
|
- to pass but "make distcheck" to fail.) Closes ticket 25814.
|
|
|
- - Our Travis CI configuration now integrates with the Coveralls
|
|
|
- coverage analysis tool. Closes ticket 25818.
|
|
|
-
|
|
|
- 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.
|
|
|
- - Check that microdesc ed25519 ids are non-zero in
|
|
|
- node_get_ed25519_id() before returning them. Implements ticket
|
|
|
- 24001, patch by "aruna1234".
|
|
|
-
|
|
|
- o Minor features (directory authority):
|
|
|
- - When directory authorities are unable to add signatures to a
|
|
|
- pending consensus, log the reason why. Closes ticket 24849.
|
|
|
-
|
|
|
- o Minor features (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.
|
|
|
- - 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 be significant for programs that 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.
|
|
|
- - Applications that want to embed Tor can now tell Tor not to
|
|
|
- register any of its own POSIX signal handlers, using the
|
|
|
- __DisableSignalHandlers option. Closes ticket 24588.
|
|
|
-
|
|
|
- o Minor features (fallback directory list):
|
|
|
- - 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 (fallback directory mirror configuration):
|
|
|
- - 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.
|
|
|
- - Stop logging excessive information about fallback netblocks.
|
|
|
- Implements ticket 24791.
|
|
|
-
|
|
|
- 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 (geoip):
|
|
|
- - Update geoip and geoip6 to the May 1 2018 Maxmind GeoLite2 Country
|
|
|
- database. Closes ticket 26104.
|
|
|
-
|
|
|
- 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, development):
|
|
|
- - Add the MainloopStats option to allow developers to get
|
|
|
- instrumentation information from the main event loop via the
|
|
|
- heartbeat messages. We hope to use this to improve Tor's behavior
|
|
|
- when it's trying to sleep. Closes ticket 24605.
|
|
|
-
|
|
|
- o Minor features (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 ticket 23827.
|
|
|
- - When a consensus has IPv6 ORPorts, make IPv6-only clients use
|
|
|
- them, rather than waiting to download microdescriptors. Implements
|
|
|
- ticket 23827.
|
|
|
-
|
|
|
- o Minor features (log messages):
|
|
|
- - Improve log message in the out-of-memory handler to include
|
|
|
- information about memory usage from the different compression
|
|
|
- backends. Closes ticket 25372.
|
|
|
- - 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):
|
|
|
- - Clarify the log messages produced when getrandom() or a related
|
|
|
- entropy-generation mechanism gives an error. Closes ticket 25120.
|
|
|
- - Added support for the Android logging subsystem. Closes
|
|
|
- ticket 24362.
|
|
|
-
|
|
|
- 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
|
|
|
- when calculating the 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, OSX, iOS):
|
|
|
- - 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, 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 (sandbox):
|
|
|
- - Explicitly permit the poll() system call when the Linux
|
|
|
- seccomp2-based sandbox is enabled: apparently, some versions of
|
|
|
- libc use poll() when calling getpwnam(). Closes ticket 25313.
|
|
|
-
|
|
|
- o Minor features (storage, configuration):
|
|
|
- - Users can 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 Minor features (testing):
|
|
|
- - Add a "make test-rust" target to run the rust tests only. Closes
|
|
|
- ticket 25071.
|
|
|
-
|
|
|
- o Minor features (testing, debugging, embedding):
|
|
|
- - 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-debugging, 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 bugfixes (build, rust):
|
|
|
- - 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.
|
|
|
- - 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 (C correctness):
|
|
|
- - Fix a very unlikely (impossible, we believe) null pointer
|
|
|
- dereference. Fixes bug 25629; bugfix on 0.2.9.15. Found by
|
|
|
- Coverity; this is CID 1430932.
|
|
|
-
|
|
|
- o Minor bugfixes (channel, client):
|
|
|
- - Better identify client connection when reporting to the geoip
|
|
|
- client cache. Fixes bug 24904; bugfix on 0.3.1.7.
|
|
|
-
|
|
|
- o Minor bugfixes (circuit, cannibalization):
|
|
|
- - Don't cannibalize preemptively-built circuits if we no longer
|
|
|
- recognize their first hop. This situation can happen if our Guard
|
|
|
- relay went off the consensus after the circuit was created. Fixes
|
|
|
- bug 24469; bugfix on 0.0.6.
|
|
|
-
|
|
|
- o Minor bugfixes (client, backport from 0.3.4.1-alpha):
|
|
|
- - Don't consider Tor running as a client if the ControlPort is open,
|
|
|
- but no actual client ports are open. Fixes bug 26062; bugfix
|
|
|
- on 0.2.9.4-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (compilation):
|
|
|
- - Fix a C99 compliance issue in our configuration script that caused
|
|
|
- compilation issues when compiling Tor with certain versions of
|
|
|
- xtools. Fixes bug 25474; bugfix on 0.3.2.5-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (controller):
|
|
|
- - Restore the correct operation of the RESOLVE command, which had
|
|
|
- been broken since we added the ability to enable/disable DNS on
|
|
|
- specific listener ports. Fixes bug 25617; bugfix on 0.2.9.3-alpha.
|
|
|
- - Avoid a (nonfatal) assertion failure when extending a one-hop
|
|
|
- circuit from the controller to become a multihop circuit. Fixes
|
|
|
- bug 24903; bugfix on 0.2.5.2-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (correctness):
|
|
|
- - Remove a nonworking, unnecessary check to see whether a circuit
|
|
|
- hop's identity digest was set when the circuit failed. Fixes bug
|
|
|
- 24927; bugfix on 0.2.4.4-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (correctness, client, backport from 0.3.4.1-alpha):
|
|
|
- - Upon receiving a malformed connected cell, stop processing the
|
|
|
- cell immediately. Previously we would mark the connection for
|
|
|
- close, but continue processing the cell as if the connection were
|
|
|
- open. Fixes bug 26072; bugfix on 0.2.4.7-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 initialize the port to zero. Fixes bug 24488; bugfix
|
|
|
- on 0.2.4.1-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (documentation):
|
|
|
- - Document that the PerConnBW{Rate,Burst} options will fall back to
|
|
|
- their corresponding consensus parameters only if those parameters
|
|
|
- are set. Previously we had claimed that these values would always
|
|
|
- be set in the consensus. Fixes bug 25296; bugfix on 0.2.2.7-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (documentation, backport from 0.3.4.1-alpha):
|
|
|
- - Stop saying in the manual that clients cache ipv4 dns answers from
|
|
|
- exit relays. We haven't used them since 0.2.6.3-alpha, and in
|
|
|
- ticket 24050 we stopped even caching them as of 0.3.2.6-alpha, but
|
|
|
- we forgot to say so in the man page. Fixes bug 26052; bugfix
|
|
|
- on 0.3.2.6-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (exit relay DNS retries):
|
|
|
- - Re-attempt timed-out DNS queries 3 times before failure, since our
|
|
|
- timeout is 5 seconds for them, but clients wait 10-15. Also allow
|
|
|
- slightly more timeouts per resolver when an exit has multiple
|
|
|
- resolvers configured. Fixes bug 21394; bugfix on 0.3.1.9.
|
|
|
-
|
|
|
- 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, bandwidth accounting, shutdown):
|
|
|
- - When hibernating, close connections normally and allow them to
|
|
|
- flush. Fixes bug 23571; bugfix on 0.2.4.7-alpha. Also fixes
|
|
|
- bug 7267.
|
|
|
- - Do not attempt to launch self-reachability tests when entering
|
|
|
- hibernation. Fixes a case 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, bridges):
|
|
|
- - Tor now always sets IPv6 preferences for bridges. Fixes bug 24573;
|
|
|
- bugfix on 0.2.8.2-alpha.
|
|
|
- - Tor now sets IPv6 address in the routerstatus as well as in the
|
|
|
- router descriptors when updating addresses for a bridge. 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 (Linux seccomp2 sandbox, backport from 0.3.4.1-alpha):
|
|
|
- - Allow the nanosleep() system call, which glibc uses to implement
|
|
|
- sleep() and usleep(). Fixes bug 24969; bugfix on 0.2.5.1-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (logging):
|
|
|
- - Fix a (mostly harmless) race condition when invoking
|
|
|
- LOG_PROTOCOL_WARN message from a subthread while the torrc options
|
|
|
- are changing. Fixes bug 23954; bugfix on 0.1.1.9-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (man page, SocksPort):
|
|
|
- - Remove dead code from the old "SocksSocket" option, and rename
|
|
|
- SocksSocketsGroupWritable to UnixSocksGroupWritable. The old
|
|
|
- option still works, but is deprecated. Fixes bug 24343; bugfix
|
|
|
- on 0.2.6.3.
|
|
|
-
|
|
|
- o Minor bugfixes (memory leaks):
|
|
|
- - 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.
|
|
|
- - Fix a harmless memory leak in tor-resolve. Fixes bug 24582; bugfix
|
|
|
- on 0.2.1.1-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (network IPv6 test):
|
|
|
- - Tor's test scripts now check 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 (networking):
|
|
|
- - string_is_valid_hostname() will not consider IP strings to be
|
|
|
- valid hostnames. Fixes bug 25055; bugfix on Tor 0.2.5.5.
|
|
|
-
|
|
|
- o Minor bugfixes (onion service v3):
|
|
|
- - Avoid an assertion failure when the next onion service descriptor
|
|
|
- rotation type is out of sync with the consensus's valid-after
|
|
|
- time. Instead, log a warning message with extra information, so we
|
|
|
- can better hunt down the cause of this assertion. Fixes bug 25306;
|
|
|
- bugfix on 0.3.2.1-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (onion service, backport from 0.3.4.1-alpha):
|
|
|
- - Fix a memory leak when a v3 onion service is configured and gets a
|
|
|
- SIGHUP signal. Fixes bug 25901; bugfix on 0.3.2.1-alpha.
|
|
|
- - When parsing the descriptor signature, look for the token plus an
|
|
|
- extra white-space at the end. This is more correct but also will
|
|
|
- allow us to support new fields that might start with "signature".
|
|
|
- Fixes bug 26069; bugfix on 0.3.0.1-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (onion services):
|
|
|
- - If we are configured to offer a single onion service, don't log
|
|
|
- long-term established one hop rendezvous points in the heartbeat.
|
|
|
- Fixes bug 25116; bugfix on 0.2.9.6-rc.
|
|
|
-
|
|
|
- o Minor bugfixes (performance):
|
|
|
- - Reduce the number of circuits that will be opened at once during
|
|
|
- the circuit build timeout phase. This is done by increasing the
|
|
|
- idle timeout to 3 minutes, and lowering the maximum number of
|
|
|
- concurrent learning circuits to 10. Fixes bug 24769; bugfix
|
|
|
- on 0.3.1.1-alpha.
|
|
|
- - Avoid calling protocol_list_supports_protocol() from inside tight
|
|
|
- loops when running with cached routerinfo_t objects. Instead,
|
|
|
- summarize the relevant protocols as flags in the routerinfo_t, as
|
|
|
- we do for routerstatus_t objects. This change simplifies our code
|
|
|
- a little, and saves a large amount of short-term memory allocation
|
|
|
- operations. Fixes bug 25008; bugfix on 0.2.9.4-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (performance, timeouts):
|
|
|
- - 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 (relay, crash, backport from 0.3.4.1-alpha):
|
|
|
- - Avoid a crash when running with DirPort set but ORPort tuned off.
|
|
|
- Fixes a case of bug 23693; bugfix on 0.3.1.1-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (Rust FFI):
|
|
|
- - Fix a minor memory leak which would happen whenever the C code
|
|
|
- would call the Rust implementation of
|
|
|
- protover_get_supported_protocols(). This was due to the C version
|
|
|
- returning a static string, whereas the Rust version newly allocated
|
|
|
- a CString to pass accross the FFI boundary. Consequently, the C
|
|
|
- code was not expecting to need to free() what it was given. Fixes
|
|
|
- bug 25127; bugfix on 0.3.2.1-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (spelling):
|
|
|
- - Use the "misspell" tool to detect and fix typos throughout the
|
|
|
- source code. Fixes bug 23650; bugfix on various versions of Tor.
|
|
|
- Patch from Deepesh Pathak.
|
|
|
-
|
|
|
- o Minor bugfixes (testing):
|
|
|
- - Avoid intermittent test failures due to a test that had relied on
|
|
|
- onion service introduction point creation finishing within 5
|
|
|
- seconds of real clock time. Fixes bug 25450; bugfix
|
|
|
- on 0.3.1.3-alpha.
|
|
|
- - Give out Exit flags in bootstrapping networks. Fixes bug 24137;
|
|
|
- bugfix on 0.2.3.1-alpha.
|
|
|
-
|
|
|
- o Minor bugfixes (unit test, monotonic time):
|
|
|
- - Increase a constant (1msec to 10msec) in the monotonic time test
|
|
|
- that makes sure the nsec/usec/msec times read are synchronized.
|
|
|
- This change was needed to accommodate slow systems like armel or
|
|
|
- when the clock_gettime() is not a VDSO on the running kernel.
|
|
|
- Fixes bug 25113; bugfix on 0.2.9.1.
|
|
|
-
|
|
|
- o Code simplification and refactoring:
|
|
|
- - Move the list of default directory authorities to its own file.
|
|
|
- Closes ticket 24854. Patch by "beastr0".
|
|
|
- - Remove the old (deterministic) directory retry logic entirely:
|
|
|
- We've used exponential backoff exclusively for some time. Closes
|
|
|
- ticket 23814.
|
|
|
- - Remove the unused nodelist_recompute_all_hsdir_indices(). Closes
|
|
|
- ticket 25108.
|
|
|
- - Remove a series of counters used to track circuit extend attempts
|
|
|
- and connection status but that in reality we aren't using for
|
|
|
- anything other than stats logged by a SIGUSR1 signal. Closes
|
|
|
- ticket 25163.
|
|
|
- - 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
|
|
|
- rather than accessing it directly. Closes ticket 23760. Patch by
|
|
|
- Neel Chauhan.
|
|
|
- - Add a function to log channels' scheduler state changes to aid
|
|
|
- debugging efforts. Closes ticket 24531.
|
|
|
-
|
|
|
- o Documentation:
|
|
|
- - Improved the documentation of AccountingStart parameter. Closes
|
|
|
- ticket 23635.
|
|
|
- - Update the documentation for "Log" to include the current list of
|
|
|
- logging domains. Closes ticket 25378.
|
|
|
- - Add documentation on how to build tor with Rust dependencies
|
|
|
- without having to be online. Closes ticket 22907; bugfix
|
|
|
- on 0.3.0.3-alpha.
|
|
|
- - Clarify the behavior of RelayBandwidth{Rate,Burst} with client
|
|
|
- traffic. Closes ticket 24318.
|
|
|
- - Document that OutboundBindAddress doesn't apply to DNS requests.
|
|
|
- Closes ticket 22145. Patch from Aruna Maurya.
|
|
|
-
|
|
|
- o Code simplification and refactoring (channels):
|
|
|
- - Remove the incoming and outgoing channel queues. These were never
|
|
|
- used, but still took up a step in our fast path.
|
|
|
- - The majority of the channel unit tests have been rewritten and the
|
|
|
- code coverage has now been raised to 83.6% for channel.c. Closes
|
|
|
- ticket 23709.
|
|
|
- - Remove other dead code from the channel subsystem: All together,
|
|
|
- this cleanup has removed more than 1500 lines of code overall and
|
|
|
- adding very little except for unit test.
|
|
|
-
|
|
|
- o Code simplification and refactoring (circuit rendezvous):
|
|
|
- - Split the client-side rendezvous circuit lookup into two
|
|
|
- functions: one that returns only established circuits and another
|
|
|
- that returns all kinds of circuits. Closes ticket 23459.
|
|
|
-
|
|
|
- o Code simplification and refactoring (controller):
|
|
|
- - Make most of the variables in networkstatus_getinfo_by_purpose()
|
|
|
- const. Implements ticket 24489.
|
|
|
-
|
|
|
- o Documentation (backport from 0.3.4.1-alpha):
|
|
|
- - Correct an IPv6 error in the documentation for ExitPolicy. Closes
|
|
|
- ticket 25857. Patch from "CTassisF".
|
|
|
-
|
|
|
- o Documentation (man page):
|
|
|
- - The HiddenServiceVersion torrc option accepts only one number:
|
|
|
- either version 2 or 3. Closes ticket 25026; bugfix
|
|
|
- on 0.3.2.2-alpha.
|
|
|
-
|
|
|
- o Documentation (manpage, denial of service):
|
|
|
- - Provide more detail about the denial-of-service options, by
|
|
|
- listing each mitigation and explaining how they relate. Closes
|
|
|
- ticket 25248.

|
|
|
Tor 0.3.1.10 backports a number of bugfixes, including important fixes for
|
|
|
security issues.
|
