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.

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. - - Changes in version 0.3.1.10 - 2018-03-03 Tor 0.3.1.10 backports a number of bugfixes, including important fixes for security issues.
