- Changes in version 0.3.5.4-alpha - 2018-11-08
- Tor 0.3.5.4-alpha includes numerous bugfixes on earlier versions and
- improves our continuous integration support. It continues our attempts
- to stabilize this alpha branch and build it into a foundation for an
- acceptable long-term-support release.
- o Major bugfixes (compilation, rust):
- - Rust tests can now build and run successfully with the
- --enable-fragile-hardening option enabled. Doing this currently
- requires the rust beta channel; it will be possible with stable
- rust once Rust version 1.31 is released. Patch from Alex Crichton.
- Fixes bugs 27272, 27273, and 27274. Bugfix on 0.3.1.1-alpha.
- o Major bugfixes (embedding, main loop):
- - When DisableNetwork becomes set, actually disable periodic events
- that are already enabled. (Previously, we would refrain from
- enabling new ones, but we would leave the old ones turned on.)
- Fixes bug 28348; bugfix on 0.3.4.1-alpha.
- o Minor features (continuous integration):
- - Add a Travis CI build for --enable-nss on Linux gcc. Closes
- ticket 27751.
- - Add new CI job to Travis configuration to run stem-based
- integration tests. Closes ticket 27913.
- o Minor features (Windows, continuous integration):
- - Build tor on Windows Server 2012 R2 and Windows Server 2016 using
- Appveyor's CI. Closes ticket 28318.
- o Minor bugfixes (C correctness, also in 0.3.4.9):
- - Avoid undefined behavior in an end-of-string check when parsing
- the BEGIN line in a directory object. Fixes bug 28202; bugfix
- on 0.2.0.3-alpha.
- o Minor bugfixes (compilation):
- - Fix a pair of missing headers on OpenBSD. Fixes bug 28303; bugfix
- on 0.3.5.1-alpha. Patch from Kris Katterjohn.
- o Minor bugfixes (compilation, OpenSolaris):
- - Fix compilation on OpenSolaris and its descendants by adding a
- missing include to compat_pthreads.c. Fixes bug 27963; bugfix
- on 0.3.5.1-alpha.
- o Minor bugfixes (configuration):
- - Refuse to start with relative file paths and RunAsDaemon set
- (regression from the fix for bug 22731). Fixes bug 28298; bugfix
- on 0.3.3.1-alpha.
- o Minor bugfixes (directory authority, also in 0.3.4.9):
- - Log additional info when we get a relay that shares an ed25519 ID
- with a different relay, instead of a BUG() warning with a
- backtrace. Fixes bug 27800; bugfix on 0.3.2.1-alpha.
- o Minor bugfixes (onion service v3):
- - Build the service descriptor's signing key certificate before
- uploading, so we always have a fresh one: leaving no chances for
- it to expire service side. Fixes bug 27838; bugfix
- on 0.3.2.1-alpha.
- o Minor bugfixes (onion service v3, client authorization):
- - Fix an assert() when adding a client authorization for the first
- time and then sending a HUP signal to the service. Before that,
- Tor would stop abruptly. Fixes bug 27995; bugfix on 0.3.5.1-alpha.
- o Minor bugfixes (onion services):
- - Unless we have explicitly set HiddenServiceVersion, detect the
- onion service version and then look for invalid options.
- Previously, we did the reverse, but that broke existing configs
- which were pointed to a v2 service and had options like
- HiddenServiceAuthorizeClient set. Fixes bug 28127; bugfix on
- 0.3.5.1-alpha. Patch by Neel Chauhan.
- o Minor bugfixes (portability):
- - Make the OPE code (which is used for v3 onion services) run
- correctly on big-endian platforms. Fixes bug 28115; bugfix
- on 0.3.5.1-alpha.
- o Minor bugfixes (protover, rust):
- - Reject extra commas in version strings. Fixes bug 27197; bugfix
- on 0.3.3.3-alpha.
- o Minor bugfixes (relay shutdown, systemd):
- - Notify systemd of ShutdownWaitLength so it can be set to longer
- than systemd's TimeoutStopSec. In Tor's systemd service file, set
- TimeoutSec to 60 seconds to allow Tor some time to shut down.
- Fixes bug 28113; bugfix on 0.2.6.2-alpha.
- o Minor bugfixes (rust, also in 0.3.4.9):
- - Fix a potential null dereference in protover_all_supported(). Add
- a test for it. Fixes bug 27804; bugfix on 0.3.3.1-alpha.
- - Return a string that can be safely freed by C code, not one
- created by the rust allocator, in protover_all_supported(). Fixes
- bug 27740; bugfix on 0.3.3.1-alpha.
- o Minor bugfixes (rust, directory authority, also in 0.3.4.9):
- - Fix an API mismatch in the rust implementation of
- protover_compute_vote(). This bug could have caused crashes on any
- directory authorities running Tor with Rust (which we do not yet
- recommend). Fixes bug 27741; bugfix on 0.3.3.6.
- o Minor bugfixes (testing):
- - Avoid hangs and race conditions in test_rebind.py. Fixes bug
- 27968; bugfix on 0.3.5.1-alpha.
- o Minor bugfixes (testing, also in 0.3.4.9):
- - Treat backtrace test failures as expected on BSD-derived systems
- (NetBSD, OpenBSD, and macOS/Darwin) until we solve bug 17808.
- (FreeBSD failures have been treated as expected since 18204 in
- 0.2.8.) Fixes bug 27948; bugfix on 0.2.5.2-alpha.
- o Documentation (onion service manpage):
- - Improve HSv3 client authorization by making some options more
- explicit and detailed. Closes ticket 28026. Patch by Mike Tigas.
- Changes in version 0.3.4.9 - 2018-11-02
- Tor 0.3.4.9 is the second stable release in its series; it backports
- numerous fixes, including a fix for a bandwidth management bug that
- was causing memory exhaustion on relays. Anyone running an earlier
- version of Tor 0.3.4.9 should upgrade.
- o Major bugfixes (compilation, backport from 0.3.5.3-alpha):
- - Fix compilation on ARM (and other less-used CPUs) when compiling
- with OpenSSL before 1.1. Fixes bug 27781; bugfix on 0.3.4.1-alpha.
- o Major bugfixes (mainloop, bootstrap, backport from 0.3.5.3-alpha):
- - Make sure Tor bootstraps and works properly if only the
- ControlPort is set. Prior to this fix, Tor would only bootstrap
- when a client port was set (Socks, Trans, NATD, DNS or HTTPTunnel
- port). Fixes bug 27849; bugfix on 0.3.4.1-alpha.
- o Major bugfixes (relay, backport from 0.3.5.3-alpha):
- - When our write bandwidth limit is exhausted, stop writing on the
- connection. Previously, we had a typo in the code that would make
- us stop reading instead, leading to relay connections being stuck
- indefinitely and consuming kernel RAM. Fixes bug 28089; bugfix
- on 0.3.4.1-alpha.
- o Major bugfixes (restart-in-process, backport from 0.3.5.1-alpha):
- - Fix a use-after-free error that could be caused by passing Tor an
- impossible set of options that would fail during options_act().
- Fixes bug 27708; bugfix on 0.3.3.1-alpha.
- o Minor features (continuous integration, backport from 0.3.5.1-alpha):
- - Don't do a distcheck with --disable-module-dirauth in Travis.
- Implements ticket 27252.
- - Only run one online rust build in Travis, to reduce network
- errors. Skip offline rust builds on Travis for Linux gcc, because
- they're redundant. Implements ticket 27252.
- - Skip gcc on OSX in Travis CI, because it's rarely used. Skip a
- duplicate hardening-off build in Travis on Tor 0.2.9. Skip gcc on
- Linux with default settings, because all the non-default builds
- use gcc on Linux. Implements ticket 27252.
- o Minor features (continuous integration, backport from 0.3.5.3-alpha):
- - Use the Travis Homebrew addon to install packages on macOS during
- Travis CI. The package list is the same, but the Homebrew addon
- does not do a `brew update` by default. Implements ticket 27738.
- o Minor features (geoip):
- - Update geoip and geoip6 to the October 9 2018 Maxmind GeoLite2
- Country database. Closes ticket 27991.
- o Minor bugfixes (32-bit OSX and iOS, timing, backport from 0.3.5.2-alpha):
- - Fix an integer overflow bug in our optimized 32-bit millisecond-
- difference algorithm for 32-bit Apple platforms. Previously, it
- would overflow when calculating the difference between two times
- more than 47 days apart. Fixes part of bug 27139; bugfix
- on 0.3.4.1-alpha.
- - Improve the precision of our 32-bit millisecond difference
- algorithm for 32-bit Apple platforms. Fixes part of bug 27139;
- bugfix on 0.3.4.1-alpha.
- - Relax the tolerance on the mainloop/update_time_jumps test when
- running on 32-bit Apple platforms. Fixes part of bug 27139; bugfix
- on 0.3.4.1-alpha.
- o Minor bugfixes (C correctness, to appear in 0.3.5.4-alpha):
- - Avoid undefined behavior in an end-of-string check when parsing
- the BEGIN line in a directory object. Fixes bug 28202; bugfix
- on 0.2.0.3-alpha.
- o Minor bugfixes (CI, appveyor, to appear in 0.3.5.4-alpha):
- - Only install the necessary mingw packages during our appveyor
- builds. This change makes the build a little faster, and prevents
- a conflict with a preinstalled mingw openssl that appveyor now
- ships. Fixes bugs 27943 and 27765; bugfix on 0.3.4.2-alpha.
- o Minor bugfixes (code safety, backport from 0.3.5.3-alpha):
- - Rewrite our assertion macros so that they no longer suppress the
- compiler's -Wparentheses warnings. Fixes bug 27709; bugfix
- o Minor bugfixes (continuous integration, backport from 0.3.5.1-alpha):
- - Stop reinstalling identical packages in our Windows CI. Fixes bug
- 27464; bugfix on 0.3.4.1-alpha.
- o Minor bugfixes (directory authority, to appear in 0.3.5.4-alpha):
- - Log additional info when we get a relay that shares an ed25519 ID
- with a different relay, instead making a BUG() warning. Fixes bug
- 27800; bugfix on 0.3.2.1-alpha.
- o Minor bugfixes (directory connection shutdown, backport from 0.3.5.1-alpha):
- - Avoid a double-close when shutting down a stalled directory
- connection. Fixes bug 26896; bugfix on 0.3.4.1-alpha.
- o Minor bugfixes (HTTP tunnel, backport from 0.3.5.1-alpha):
- - Fix a bug warning when closing an HTTP tunnel connection due to an
- HTTP request we couldn't handle. Fixes bug 26470; bugfix
- on 0.3.2.1-alpha.
- o Minor bugfixes (netflow padding, backport from 0.3.5.1-alpha):
- - Ensure circuitmux queues are empty before scheduling or sending
- padding. Fixes bug 25505; bugfix on 0.3.1.1-alpha.
- o Minor bugfixes (onion service v3, backport from 0.3.5.1-alpha):
- - When the onion service directory can't be created or has the wrong
- permissions, do not log a stack trace. Fixes bug 27335; bugfix
- on 0.3.2.1-alpha.
- o Minor bugfixes (onion service v3, backport from 0.3.5.2-alpha):
- - Close all SOCKS request (for the same .onion) if the newly fetched
- descriptor is unusable. Before that, we would close only the first
- one leaving the other hanging and let to time out by themselves.
- Fixes bug 27410; bugfix on 0.3.2.1-alpha.
- o Minor bugfixes (onion service v3, backport from 0.3.5.3-alpha):
- - When selecting a v3 rendezvous point, don't only look at the
- protover, but also check whether the curve25519 onion key is
- present. This way we avoid picking a relay that supports the v3
- rendezvous but for which we don't have the microdescriptor. Fixes
- bug 27797; bugfix on 0.3.2.1-alpha.
- o Minor bugfixes (protover, backport from 0.3.5.3-alpha):
- - Reject protocol names containing bytes other than alphanumeric
- characters and hyphens ([A-Za-z0-9-]). Fixes bug 27316; bugfix
- on 0.2.9.4-alpha.
- o Minor bugfixes (rust, backport from 0.3.5.1-alpha):
- - Compute protover votes correctly in the rust version of the
- protover code. Previously, the protover rewrite in 24031 allowed
- repeated votes from the same voter for the same protocol version
- to be counted multiple times in protover_compute_vote(). Fixes bug
- 27649; bugfix on 0.3.3.5-rc.
- - Reject protover names that contain invalid characters. Fixes bug
- 27687; bugfix on 0.3.3.1-alpha.
- o Minor bugfixes (rust, backport from 0.3.5.2-alpha):
- - protover_all_supported() would attempt to allocate up to 16GB on
- some inputs, leading to a potential memory DoS. Fixes bug 27206;
- bugfix on 0.3.3.5-rc.
- o Minor bugfixes (rust, directory authority, to appear in 0.3.5.4-alpha):
- - Fix an API mismatch in the rust implementation of
- protover_compute_vote(). This bug could have caused crashes on any
- directory authorities running Tor with Rust (which we do not yet
- recommend). Fixes bug 27741; bugfix on 0.3.3.6.
- o Minor bugfixes (rust, to appear in 0.3.5.4-alpha):
- - Fix a potential null dereference in protover_all_supported(). Add
- a test for it. Fixes bug 27804; bugfix on 0.3.3.1-alpha.
- - Return a string that can be safely freed by C code, not one
- created by the rust allocator, in protover_all_supported(). Fixes
- bug 27740; bugfix on 0.3.3.1-alpha.
- o Minor bugfixes (testing, backport from 0.3.5.1-alpha):
- - If a unit test running in a subprocess exits abnormally or with a
- nonzero status code, treat the test as having failed, even if the
- test reported success. Without this fix, memory leaks don't cause
- the tests to fail, even with LeakSanitizer. Fixes bug 27658;
- bugfix on 0.2.2.4-alpha.
- o Minor bugfixes (testing, backport from 0.3.5.3-alpha):
- - Make the hs_service tests use the same time source when creating
- the introduction point and when testing it. Now tests work better
- on very slow systems like ARM or Travis. Fixes bug 27810; bugfix
- on 0.3.2.1-alpha.
- o Minor bugfixes (testing, to appear in 0.3.5.4-alpha):
- - Treat backtrace test failures as expected on BSD-derived systems
- (NetBSD, OpenBSD, and macOS/Darwin) until we solve bug 17808.
- (FreeBSD failures have been treated as expected since 18204 in
- 0.2.8.) Fixes bug 27948; bugfix on 0.2.5.2-alpha.
- Changes in version 0.3.5.3-alpha - 2018-10-17
- Tor 0.3.5.3-alpha fixes several bugs, mostly from previous 0.3.5.x
- versions. One important fix for relays addresses a problem with rate-
- limiting code from back in 0.3.4.x: If the fix works out, we'll be
- backporting it soon. This release is still an alpha, but we hope it's
- getting closer and closer to stability.
- o Major features (onion services):
- - Version 3 onion services can now use the per-service
- HiddenServiceExportCircuitID option to differentiate client
- circuits. It communicates with the service by using the HAProxy
- protocol to assign virtual IP addresses to inbound client
- circuits. Closes ticket 4700. Patch by Mahrud Sayrafi.
- o Major bugfixes (compilation):
- - Fix compilation on ARM (and other less-used CPUs) when compiling
- with OpenSSL before 1.1. Fixes bug 27781; bugfix on 0.3.4.1-alpha.
- o Major bugfixes (initialization, crash):
- - Fix an assertion crash that would stop Tor from starting up if it
- tried to activate a periodic event too early. Fixes bug 27861;
- bugfix on 0.3.5.1-alpha.
- o Major bugfixes (mainloop, bootstrap):
- - Make sure Tor bootstraps and works properly if only the
- ControlPort is set. Prior to this fix, Tor would only bootstrap
- when a client port was set (Socks, Trans, NATD, DNS or HTTPTunnel
- port). Fixes bug 27849; bugfix on 0.3.4.1-alpha.
- o Major bugfixes (relay):
- - When our write bandwidth limit is exhausted, stop writing on the
- connection. Previously, we had a typo in the code that would make
- us stop reading instead, leading to relay connections being stuck
- indefinitely and consuming kernel RAM. Fixes bug 28089; bugfix
- on 0.3.4.1-alpha.
- o Minor features (continuous integration):
- - Use the Travis Homebrew addon to install packages on macOS during
- Travis CI. The package list is the same, but the Homebrew addon
- does not do a `brew update` by default. Implements ticket 27738.
- - Report what program produced the mysterious core file that we
- occasionally see on Travis CI during make distcheck. Closes
- ticket 28024.
- o Minor features (geoip):
- - Update geoip and geoip6 to the October 9 2018 Maxmind GeoLite2
- Country database. Closes ticket 27991.
- o Minor bugfixes (code safety):
- - Rewrite our assertion macros so that they no longer suppress the
- compiler's -Wparentheses warnings. Fixes bug 27709; bugfix
- on 0.0.6.
- o Minor bugfixes (compilation):
- - Compile the ed25519-donna code with a correct declaration of
- crypto_strongest_rand(). Previously, we built it with one type,
- but linked it against another in the unit tests, which caused
- compilation failures with LTO enabled. This could have caused
- other undefined behavior in the tests. Fixes bug 27728; bugfix
- on 0.3.5.1-alpha.
- o Minor bugfixes (compilation, netbsd):
- - Add a missing include back into procmon.c. Fixes bug 27990; bugfix
- on 0.3.5.1-alpha.
- o Minor bugfixes (continuous integration, appveyor):
- - Install only the necessary mingw packages during our appveyor
- builds. This change makes the build a little faster, and prevents
- a conflict with a preinstalled mingw openssl that appveyor now
- ships. Fixes bugs 27765 and 27943; bugfix on 0.3.4.2-alpha.
- o Minor bugfixes (directory permissions):
- - When a user requests a group-readable DataDirectory, give it to
- them. Previously, when the DataDirectory and the CacheDirectory
- were the same, the default setting (0) for
- CacheDirectoryGroupReadable would override the setting for
- DataDirectoryGroupReadable. Fixes bug 26913; bugfix
- on 0.3.3.1-alpha.
- o Minor bugfixes (memory leaks):
- - Fix a small memory leak when calling Tor with --dump-config. Fixes
- bug 27893; bugfix on 0.3.2.1-alpha.
- o Minor bugfixes (networking):
- - In retry_listeners_ports(), make sure that we're removing a member
- of old_conns smartlist at most once. Fixes bug 27808; bugfix
- on 0.3.5.1-alpha.
- - Refrain from attempting socket rebinding when old and new
- listeners are in different address families. Fixes bug 27928;
- bugfix on 0.3.5.1-alpha.
- o Minor bugfixes (onion service v3):
- - Stop dumping a stack trace when trying to connect to an intro
- point without having a descriptor for it. Fixes bug 27774; bugfix
- on 0.3.2.1-alpha.
- - Don't warn so loudly when Tor is unable to decode an onion
- descriptor. This can now happen as a normal use case if a client
- gets a descriptor with client authorization but the client is not
- authorized. Fixes bug 27550; bugfix on 0.3.5.1-alpha.
- - When selecting a v3 rendezvous point, don't only look at the
- protover, but also check whether the curve25519 onion key is
- present. This way we avoid picking a relay that supports the v3
- rendezvous but for which we don't have the microdescriptor. Fixes
- bug 27797; bugfix on 0.3.2.1-alpha.
- o Minor bugfixes (protover):
- - Reject protocol names containing bytes other than alphanumeric
- characters and hyphens ([A-Za-z0-9-]). Fixes bug 27316; bugfix
- on 0.2.9.4-alpha.
- o Minor bugfixes (testing):
- - Make the hs_service tests use the same time source when creating
- the introduction point and when testing it. Now tests work better
- on very slow systems like ARM or Travis. Fixes bug 27810; bugfix
- on 0.3.2.1-alpha.
- - In test_rebind.py, check if the Python version is in the supported
- range. Fixes bug 27675; bugfix on 0.3.5.1-alpha.
- o Code simplification and refactoring:
- - Divide more large Tor source files -- especially ones that span
- multiple areas of functionality -- into smaller parts, including
- onion.c and main.c. Closes ticket 26747.
- - Divide the "routerparse.c" module into separate modules for each
- group of parsed objects. Closes ticket 27924.
- - Move protover_rust.c to the same place protover.c was moved to.
- Closes ticket 27814.
- - Split directory.c into separate pieces for client, server, and
- common functionality. Closes ticket 26744.
- - Split the non-statistics-related parts from the rephist.c and
- geoip.c modules. Closes ticket 27892.
- - Split the router.c file into relay-only and shared components, to
- help with future modularization. Closes ticket 27864.
- o Documentation:
- - In the tor-resolve(1) manpage, fix the reference to socks-
- extensions.txt by adding a web URL. Resolves ticket 27853.
- - Mention that we require Python to be 2.7 or newer for some
- integration tests that we ship with Tor. Resolves ticket 27677.
- Changes in version 0.3.5.2-alpha - 2018-09-21
- Tor 0.3.5.2-alpha fixes several bugs in 0.3.5.1-alpha, including one
- that made Tor think it had run out of sockets. Anybody running a relay
- or an onion service on 0.3.5.1-alpha should upgrade.
- o Major bugfixes (relay bandwidth statistics):
- - When we close relayed circuits, report the data in the circuit
- queues as being written in our relay bandwidth stats. This
- mitigates guard discovery and other attacks that close circuits
- for the explicit purpose of noticing this discrepancy in
- statistics. Fixes bug 23512; bugfix on 0.0.8pre3.
- o Major bugfixes (socket accounting):
- - In our socket accounting code, count a socket as closed even when
- it is closed indirectly by the TLS layer. Previously, we would
- count these sockets as still in use, and incorrectly believe that
- we had run out of sockets. Fixes bug 27795; bugfix
- on 0.3.5.1-alpha.
- o Minor bugfixes (32-bit OSX and iOS, timing):
- - Fix an integer overflow bug in our optimized 32-bit millisecond-
- difference algorithm for 32-bit Apple platforms. Previously, it
- would overflow when calculating the difference between two times
- more than 47 days apart. Fixes part of bug 27139; bugfix
- on 0.3.4.1-alpha.
- - Improve the precision of our 32-bit millisecond difference
- algorithm for 32-bit Apple platforms. Fixes part of bug 27139;
- bugfix on 0.3.4.1-alpha.
- - Relax the tolerance on the mainloop/update_time_jumps test when
- running on 32-bit Apple platforms. Fixes part of bug 27139; bugfix
- on 0.3.4.1-alpha.
- o Minor bugfixes (onion service v3):
- - Close all SOCKS request (for the same .onion) if the newly fetched
- descriptor is unusable. Before that, we would close only the first
- one leaving the other hanging and let to time out by themselves.
- Fixes bug 27410; bugfix on 0.3.2.1-alpha.
- o Minor bugfixes (memory leak):
- - Fix an unlikely memory leak when trying to read a private key from
- a ridiculously large file. Fixes bug 27764; bugfix on
- 0.3.5.1-alpha. This is CID 1439488.
- o Minor bugfixes (NSS):
- - Correctly detect failure to open a dummy TCP socket when stealing
- ownership of an fd from the NSS layer. Fixes bug 27782; bugfix
- on 0.3.5.1-alpha.
- o Minor bugfixes (rust):
- - protover_all_supported() would attempt to allocate up to 16GB on
- some inputs, leading to a potential memory DoS. Fixes bug 27206;
- bugfix on 0.3.3.5-rc.
- o Minor bugfixes (testing):
- - Revise the "conditionvar_timeout" test so that it succeeds even on
- heavily loaded systems where the test threads are not scheduled
- within 200 msec. Fixes bug 27073; bugfix on 0.2.6.3-alpha.
- o Code simplification and refactoring:
- - Divide the routerlist.c and dirserv.c modules into smaller parts.
- Closes ticket 27799.
- Changes in version 0.3.5.1-alpha - 2018-09-18
- Tor 0.3.5.1-alpha is the first release of the 0.3.5.x series. It adds
- client authorization for modern (v3) onion services, improves
- bootstrap reporting, begins reorganizing Tor's codebase, adds optional
- support for NSS in place of OpenSSL, and much more.
- o Major features (onion services, UI change):
- - For a newly created onion service, the default version is now 3.
- Tor still supports existing version 2 services, but the operator
- now needs to set "HiddenServiceVersion 2" in order to create a new
- version 2 service. For existing services, Tor now learns the
- version by reading the key file. Closes ticket 27215.
- o Major features (relay, UI change):
- - Relays no longer run as exits by default. If the "ExitRelay"
- option is auto (or unset), and no exit policy is specified with
- ExitPolicy or ReducedExitPolicy, we now treat ExitRelay as 0.
- Previously in this case, we allowed exit traffic and logged a
- warning message. Closes ticket 21530. Patch by Neel Chauhan.
- - Tor now validates that the ContactInfo config option is valid UTF-
- 8 when parsing torrc. Closes ticket 27428.
- o Major features (bootstrap):
- - Don't report directory progress until after a connection to a
- relay or bridge has succeeded. Previously, we'd report 80%
- progress based on cached directory information when we couldn't
- even connect to the network. Closes ticket 27169.
- o Major features (new code layout):
- - Nearly all of Tor's source code has been moved around into more
- logical places. The "common" directory is now divided into a set
- of libraries in "lib", and files in the "or" directory have been
- split into "core" (logic absolutely needed for onion routing),
- "feature" (independent modules in Tor), and "app" (to configure
- and invoke the rest of Tor). See doc/HACKING/CodeStructure.md for
- more information. Closes ticket 26481.
- This refactoring is not complete: although the libraries have been
- refactored to be acyclic, the main body of Tor is still too
- interconnected. We will attempt to improve this in the future.
- o Major features (onion services v3):
- - Implement onion service client authorization at the descriptor
- level: only authorized clients can decrypt a service's descriptor
- to find out how to contact it. A new torrc option was added to
- control this client side: ClientOnionAuthDir <path>. On the
- service side, if the "authorized_clients/" directory exists in the
- onion service directory path, client configurations are read from
- the files within. See the manpage for more details. Closes ticket
- 27547. Patch done by Suphanat Chunhapanya (haxxpop).
- - Improve revision counter generation in next-gen onion services.
- Onion services can now scale by hosting multiple instances on
- different hosts without synchronization between them, which was
- previously impossible because descriptors would get rejected by
- HSDirs. Addresses ticket 25552.
- o Major features (portability, cryptography, experimental, TLS):
- - Tor now has the option to compile with the NSS library instead of
- OpenSSL. This feature is experimental, and we expect that bugs may
- remain. It is mainly intended for environments where Tor's
- performance is not CPU-bound, and where NSS is already known to be
- installed. To try it out, configure Tor with the --enable-nss
- flag. Closes tickets 26631, 26815, and 26816.
- If you are experimenting with this option and using an old cached
- consensus, Tor may fail to start. To solve this, delete your
- "cached-consensus" and "cached-microdesc-consensus" files,
- (if present), and restart Tor.
- o Major bugfixes (directory authority):
- - Actually check that the address we get from DirAuthority
- configuration line is valid IPv4. Explicitly disallow DirAuthority
- address to be a DNS hostname. Fixes bug 26488; bugfix
- on 0.1.2.10-rc.
- o Major bugfixes (restart-in-process):
- - Fix a use-after-free error that could be caused by passing Tor an
- impossible set of options that would fail during options_act().
- Fixes bug 27708; bugfix on 0.3.3.1-alpha.
- o Minor features (admin tools):
- - Add a new --key-expiration option to print the expiration date of
- the signing cert in an ed25519_signing_cert file. Resolves
- issue 19506.
- o Minor features (build):
- - If you pass the "--enable-pic" option to configure, Tor will try
- to tell the compiler to build position-independent code suitable
- to link into a dynamic library. (The default remains -fPIE, for
- code suitable for a relocatable executable.) Closes ticket 23846.
- o Minor features (code correctness, testing):
- - Tor's build process now includes a "check-includes" make target to
- verify that no module of Tor relies on any headers from a higher-
- level module. We hope to use this feature over time to help
- refactor our codebase. Closes ticket 26447.
- o Minor features (code layout):
- - We have a new "lowest-level" error-handling API for use by code
- invoked from within the logging module. With this interface, the
- logging code is no longer at risk of calling into itself if a
- failure occurs while it is trying to log something. Closes
- ticket 26427.
- o Minor features (compilation):
- - Tor's configure script now supports a --with-malloc= option to
- select your malloc implementation. Supported options are
- "tcmalloc", "jemalloc", "openbsd" (deprecated), and "system" (the
- default). Addresses part of ticket 20424. Based on a patch from
- Alex Xu.
- o Minor features (config):
- - The "auto" keyword in torrc is now case-insensitive. Closes
- ticket 26663.
- o Minor features (continuous integration):
- - Don't do a distcheck with --disable-module-dirauth in Travis.
- Implements ticket 27252.
- - Install libcap-dev and libseccomp2-dev so these optional
- dependencies get tested on Travis CI. Closes ticket 26560.
- - Only run one online rust build in Travis, to reduce network
- errors. Skip offline rust builds on Travis for Linux gcc, because
- they're redundant. Implements ticket 27252.
- - Skip gcc on OSX in Travis CI, because it's rarely used. Skip a
- duplicate hardening-off build in Travis on Tor 0.2.9. Skip gcc on
- Linux with default settings, because all the non-default builds
- use gcc on Linux. Implements ticket 27252.
- o Minor features (controller):
- - Emit CIRC_BW events as soon as we detect that we processed an
- invalid or otherwise dropped cell on a circuit. This allows
- vanguards and other controllers to react more quickly to dropped
- cells. Closes ticket 27678.
- - For purposes of CIRC_BW-based dropped cell detection, track half-
- closed stream ids, and allow their ENDs, SENDMEs, DATA and path
- bias check cells to arrive without counting it as dropped until
- either the END arrives, or the windows are empty. Closes
- ticket 25573.
- - Implement a 'GETINFO md/all' controller command to enable getting
- all known microdescriptors. Closes ticket 8323.
- - The GETINFO command now support an "uptime" argument, to return
- Tor's uptime in seconds. Closes ticket 25132.
- o Minor features (denial-of-service avoidance):
- - Make our OOM handler aware of the DNS cache so that it doesn't
- fill up the memory. This check is important for our DoS mitigation
- subsystem. Closes ticket 18642. Patch by Neel Chauhan.
- o Minor features (development):
- - Tor's makefile now supports running the "clippy" Rust style tool
- on our Rust code. Closes ticket 22156.
- o Minor features (directory authority):
- - There is no longer an artificial upper limit on the length of
- bandwidth lines. Closes ticket 26223.
- - When a bandwidth file is used to obtain the bandwidth measurements,
- include this bandwidth file headers in the votes. Closes
- ticket 3723.
- - Improved support for networks with only a single authority or a
- single fallback directory. Patch from Gabriel Somlo. Closes
- ticket 25928.
- o Minor features (embedding API):
- - The Tor controller API now supports a function to launch Tor with
- a preconstructed owning controller FD, so that embedding
- applications don't need to manage controller ports and
- authentication. Closes ticket 24204.
- - The Tor controller API now has a function that returns the name
- and version of the backend implementing the API. Closes
- ticket 26947.
- o Minor features (geoip):
- - Update geoip and geoip6 to the September 6 2018 Maxmind GeoLite2
- Country database. Closes ticket 27631.
- o Minor features (memory management):
- - Get Libevent to use the same memory allocator as Tor, by calling
- event_set_mem_functions() during initialization. Resolves
- ticket 8415.
- o Minor features (memory usage):
- - When not using them, store legacy TAP public onion keys in DER-
- encoded format, rather than as expanded public keys. This should
- save several megabytes on typical clients. Closes ticket 27246.
- o Minor features (OpenSSL):
- - When possible, use RFC5869 HKDF implementation from OpenSSL rather
- than our own. Resolves ticket 19979.
- o Minor features (Rust, code quality):
- - Improve rust code quality in the rust protover implementation by
- making it more idiomatic. Includes changing an internal API to
- take &str instead of &String. Closes ticket 26492.
- o Minor features (testing):
- - Add scripts/test/chutney-git-bisect.sh, for bisecting using
- chutney. Implements ticket 27211.
- o Minor features (tor-resolve):
- - The tor-resolve utility can now be used with IPv6 SOCKS proxies.
- Side-effect of the refactoring for ticket 26526.
- o Minor features (UI):
- - Log each included configuration file or directory as we read it,
- to provide more visibility about where Tor is reading from. Patch
- from Unto Sten; closes ticket 27186.
- - Lower log level of "Scheduler type KIST has been enabled" to INFO.
- Closes ticket 26703.
- o Minor bugfixes (bootstrap):
- - Try harder to get descriptors in non-exit test networks, by using
- the mid weight for the third hop when there are no exits. Fixes
- bug 27237; bugfix on 0.2.6.2-alpha.
- o Minor bugfixes (C correctness):
- - Avoid casting smartlist index to int implicitly, as it may trigger
- a warning (-Wshorten-64-to-32). Fixes bug 26282; bugfix on
- 0.2.3.13-alpha, 0.2.7.1-alpha and 0.2.1.1-alpha.
- - Use time_t for all values in
- predicted_ports_prediction_time_remaining(). Rework the code that
- computes difference between durations/timestamps. Fixes bug 27165;
- bugfix on 0.3.1.1-alpha.
- o Minor bugfixes (client, memory usage):
- - When not running as a directory cache, there is no need to store
- the text of the current consensus networkstatus in RAM.
- Previously, however, clients would store it anyway, at a cost of
- over 5 MB. Now, they do not. Fixes bug 27247; bugfix
- on 0.3.0.1-alpha.
- o Minor bugfixes (client, reachableaddresses):
- - Instead of adding a "reject *:*" line to ReachableAddresses when
- loading the configuration, add one to the policy after parsing it
- in parse_reachable_addresses(). This prevents extra "reject *.*"
- lines from accumulating on reloads. Fixes bug 20874; bugfix on
- 0.1.1.5-alpha. Patch by Neel Chauhan.
- o Minor bugfixes (code quality):
- - Rename sandbox_getaddrinfo() and other functions to no longer
- misleadingly suggest that they are sandbox-only. Fixes bug 26525;
- bugfix on 0.2.7.1-alpha.
- o Minor bugfixes (configuration, Onion Services):
- - In rend_service_parse_port_config(), disallow any input to remain
- after address-port pair was parsed. This will catch address and
- port being whitespace-separated by mistake of the user. Fixes bug
- 27044; bugfix on 0.2.9.10.
- o Minor bugfixes (continuous integration):
- - Stop reinstalling identical packages in our Windows CI. Fixes bug
- 27464; bugfix on 0.3.4.1-alpha.
- o Minor bugfixes (controller):
- - Consider all routerinfo errors other than "not a server" to be
- transient for the purpose of "GETINFO exit-policy/*" controller
- request. Print stacktrace in the unlikely case of failing to
- recompute routerinfo digest. Fixes bug 27034; bugfix
- on 0.3.4.1-alpha.
- o Minor bugfixes (directory connection shutdown):
- - Avoid a double-close when shutting down a stalled directory
- connection. Fixes bug 26896; bugfix on 0.3.4.1-alpha.
- o Minor bugfixes (HTTP tunnel):
- - Fix a bug warning when closing an HTTP tunnel connection due to an
- HTTP request we couldn't handle. Fixes bug 26470; bugfix
- on 0.3.2.1-alpha.
- o Minor bugfixes (ipv6):
- - In addrs_in_same_network_family(), we choose the subnet size based
- on the IP version (IPv4 or IPv6). Previously, we chose a fixed
- subnet size of /16 for both IPv4 and IPv6 addresses. Fixes bug
- 15518; bugfix on 0.2.3.1-alpha. Patch by Neel Chauhan.
- o Minor bugfixes (logging):
- - As a precaution, do an early return from log_addr_has_changed() if
- Tor is running as client. Also, log a stack trace for debugging as
- this function should only be called when Tor runs as server. Fixes
- bug 26892; bugfix on 0.1.1.9-alpha.
- - Refrain from mentioning bug 21018 in the logs, as it is already
- fixed. Fixes bug 25477; bugfix on 0.2.9.8.
- o Minor bugfixes (logging, documentation):
- - When SafeLogging is enabled, scrub IP address in
- channel_tls_process_netinfo_cell(). Also, add a note to manpage
- that scrubbing is not guaranteed on loglevels below Notice. Fixes
- bug 26882; bugfix on 0.2.4.10-alpha.
- o Minor bugfixes (netflow padding):
- - Ensure circuitmux queues are empty before scheduling or sending
- padding. Fixes bug 25505; bugfix on 0.3.1.1-alpha.
- o Minor bugfixes (onion service v2):
- - Log at level "info", not "warning", in the case that we do not
- have a consensus when a .onion request comes in. This can happen
- normally while bootstrapping. Fixes bug 27040; bugfix
- on 0.2.8.2-alpha.
- o Minor bugfixes (onion service v3):
- - When the onion service directory can't be created or has the wrong
- permissions, do not log a stack trace. Fixes bug 27335; bugfix
- on 0.3.2.1-alpha.
- o Minor bugfixes (OS compatibility):
- - Properly handle configuration changes that move a listener to/from
- wildcard IP address. If the first attempt to bind a socket fails,
- close the old listener and try binding the socket again. Fixes bug
- 17873; bugfix on 0.0.8pre-1.
- o Minor bugfixes (performance)::
- - Rework node_is_a_configured_bridge() to no longer call
- node_get_all_orports(), which was performing too many memory
- allocations. Fixes bug 27224; bugfix on 0.2.3.9.
- o Minor bugfixes (relay statistics):
- - Update relay descriptor on bandwidth changes only when the uptime
- is smaller than 24h, in order to reduce the efficiency of guard
- discovery attacks. Fixes bug 24104; bugfix on 0.1.1.6-alpha.
- o Minor bugfixes (relays):
- - Consider the fact that we'll be making direct connections to our
- entry and guard nodes when computing the fraction of nodes that
- have their descriptors. Also, if we are using bridges and there is
- at least one bridge with a full descriptor, treat the fraction of
- guards available as 100%. Fixes bug 25886; bugfix on 0.2.4.10-alpha.
- Patch by Neel Chauhan.
- - Update the message logged on relays when DirCache is disabled.
- Since 0.3.3.5-rc, authorities require DirCache (V2Dir) for the
- Guard flag. Fixes bug 24312; bugfix on 0.3.3.5-rc.
- o Minor bugfixes (rust, protover):
- - Compute protover votes correctly in the rust version of the
- protover code. Previously, the protover rewrite in 24031 allowed
- repeated votes from the same voter for the same protocol version
- to be counted multiple times in protover_compute_vote(). Fixes bug
- 27649; bugfix on 0.3.3.5-rc.
- - Reject protover names that contain invalid characters. Fixes bug
- 27687; bugfix on 0.3.3.1-alpha.
- o Minor bugfixes (testing):
- - Fix two unit tests to work when HOME environment variable is not
- set. Fixes bug 27096; bugfix on 0.2.8.1-alpha.
- - If a unit test running in a subprocess exits abnormally or with a
- nonzero status code, treat the test as having failed, even if the
- test reported success. Without this fix, memory leaks don't cause
- the tests to fail, even with LeakSanitizer. Fixes bug 27658;
- bugfix on 0.2.2.4-alpha.
- - When logging a version mismatch in our openssl_version tests,
- report the actual offending version strings. Fixes bug 26152;
- bugfix on 0.2.9.1-alpha.
- - Fix forking tests on Windows when there is a space somewhere in
- the path. Fixes bug 26437; bugfix on 0.2.2.4-alpha.
- o Code simplification and refactoring:
- - 'updateFallbackDirs.py' now ignores the blacklist file, as it's not
- longer needed. Closes ticket 26502.
- - Include paths to header files within Tor are now qualified by
- directory within the top-level src directory.
- - Many structures have been removed from the centralized "or.h"
- header, and moved into their own headers. This will allow us to
- reduce the number of places in the code that rely on each
- structure's contents and layout. Closes ticket 26383.
- - Remove ATTR_NONNULL macro from codebase. Resolves ticket 26527.
- - Remove GetAdaptersAddresses_fn_t. The code that used it was
- removed as part of the 26481 refactor. Closes ticket 27467.
- - Rework Tor SOCKS server code to use Trunnel and benefit from
- autogenerated functions for parsing and generating SOCKS wire
- format. New implementation is cleaner, more maintainable and
- should be less prone to heartbleed-style vulnerabilities.
- Implements a significant fraction of ticket 3569.
- - Split sampled_guards_update_from_consensus() and
- select_entry_guard_for_circuit() into subfunctions. In
- entry_guards_update_primary() unite three smartlist enumerations
- into one and move smartlist comparison code out of the function.
- Closes ticket 21349.
- - Tor now assumes that you have standards-conformant stdint.h and
- inttypes.h headers when compiling. Closes ticket 26626.
- - Unify our bloom filter logic. Previously we had two copies of this
- code: one for routerlist filtering, and one for address set
- calculations. Closes ticket 26510.
- - Use the simpler strcmpstart() helper in
- rend_parse_v2_service_descriptor instead of strncmp(). Closes
- ticket 27630.
- - Utility functions that can perform a DNS lookup are now wholly
- separated from those that can't, in separate headers and C
- modules. Closes ticket 26526.
- o Documentation:
- - Copy paragraph and URL to Tor's code of conduct document from
- CONTRIBUTING to new CODE_OF_CONDUCT file. Resolves ticket 26638.
- - Remove old instructions from INSTALL document. Closes ticket 26588.
- - Warn users that they should not include MyFamily line(s) in their
- torrc when running Tor bridge. Closes ticket 26908.
- o Removed features:
- - Tor no longer supports building with the dmalloc library. For
- debugging memory issues, we suggest using gperftools or msan
- instead. Closes ticket 26426.
- - Tor no longer attempts to run on Windows environments without the
- GetAdaptersAddresses() function. This function has existed since
- Windows XP, which is itself already older than we support.
- - Remove Tor2web functionality for version 2 onion services. The
- Tor2webMode and Tor2webRendezvousPoints options are now obsolete.
- (This feature was never shipped in vanilla Tor and it was only
- possible to use this feature by building the support at compile
- time. Tor2webMode is not implemented for version 3 onion services.)
- Closes ticket 26367.
- Changes in version 0.2.9.17 - 2018-09-10
- Tor 0.2.9.17 backports numerous bugfixes from later versions of Tor.
- o Minor features (compatibility, backport from 0.3.4.8):
- - Tell OpenSSL to maintain backward compatibility with previous
- RSA1024/DH1024 users in Tor. With OpenSSL 1.1.1-pre6, these
- ciphers are disabled by default. Closes ticket 27344.
- o Minor features (continuous integration, backport from 0.3.4.7-rc):
- - Enable macOS builds in our Travis CI configuration. Closes
- ticket 24629.

- dependencies get tested on Travis CI. Closes ticket 26560.
- - Run asciidoc during Travis CI. Implements ticket 27087.
- - Use ccache in our Travis CI configuration. Closes ticket 26952.
- o Minor features (geoip):
- - Update geoip and geoip6 to the August 7 2018 Maxmind GeoLite2
- Country database. Closes ticket 27089.

- o Minor bugfixes (compilation, backport from 0.3.4.7-rc):
- - Silence a spurious compiler warning on the GetAdaptersAddresses
- function pointer cast. This issue is already fixed by 26481 in
- 0.3.5 and later, by removing the lookup and cast. Fixes bug 27465;
- bugfix on 0.2.3.11-alpha.
- - Stop calling SetProcessDEPPolicy() on 64-bit Windows. It is not
- supported, and always fails. Some compilers warn about the

- on 0.2.2.23-alpha.
- o Minor bugfixes (compilation, windows, backport from 0.3.4.7-rc):
- - Don't link or search for pthreads when building for Windows, even
- if we are using build environment (like mingw) that provides a
- pthreads library. Fixes bug 27081; bugfix on 0.1.0.1-rc.
- o Minor bugfixes (continuous integration, backport from 0.3.4.6-rc):
- - Skip a pair of unreliable key generation tests on Windows, until

- bug 26853; bugfix on 0.2.7.3-rc and 0.3.2.1-alpha respectively.
- o Minor bugfixes (continuous integration, backport from 0.3.4.7-rc):
- - Pass the module flags to distcheck configure, and log the flags
- before running configure. (Backported to 0.2.9 and later as a
- precaution.) Fixes bug 27088; bugfix on 0.3.4.1-alpha.
- o Minor bugfixes (continuous integration, backport from 0.3.4.8):
- - When a Travis build fails, and showing a log fails, keep trying to
- show the other logs. Fixes bug 27453; bugfix on 0.3.4.7-rc.
- - When we use echo in Travis, don't pass a --flag as the first
- argument. Fixes bug 27418; bugfix on 0.3.4.7-rc.
- o Minor bugfixes (directory authority, backport from 0.3.4.6-rc):
- - When voting for recommended versions, make sure that all of the
- versions are well-formed and parsable. Fixes bug 26485; bugfix
- on 0.1.1.6-alpha.
- o Minor bugfixes (linux seccomp2 sandbox, backport from 0.3.4.7-rc):
- - Fix a bug in out sandboxing rules for the openat() syscall.
- Previously, no openat() call would be permitted, which would break
- filesystem operations on recent glibc versions. Fixes bug 25440;
- bugfix on 0.2.9.15. Diagnosis and patch from Daniel Pinto.
- o Minor bugfixes (onion services, backport from 0.3.4.8):
- - Silence a spurious compiler warning in

- net/listeners/extor respectively. Closes ticket 26647.
- o Minor features (directory authorities, backport from 0.3.4.7-rc):
- - Authorities no longer vote to make the subprotocol version
- "LinkAuth=1" a requirement: it is unsupportable with NSS, and
- hasn't been needed since Tor 0.3.0.1-alpha. Closes ticket 27286.
- o Minor features (geoip):

- o Minor bugfixes (testing, chutney, backport from 0.3.4.8):
- - When running make test-network-all, use the mixed+hs-v2 network.
- (A previous fix to chutney removed v3 onion services from the
- mixed+hs-v23 network, so seeing "mixed+hs-v23" in tests is
- confusing.) Fixes bug 27345; bugfix on 0.3.2.1-alpha.
- - Before running make test-network-all, delete old logs and test
- result files, to avoid spurious failures. Fixes bug 27295; bugfix
- on 0.2.7.3-rc.

- header, but where C11 atomic functions don't actually compile.
- Closes ticket 26779; workaround for Debian issue 903709.
- o Minor features (compatibility, backport from 0.3.4.8):

- o Minor features (directory authorities, backport from 0.3.4.7-rc):
- - Authorities no longer vote to make the subprotocol version
- "LinkAuth=1" a requirement: it is unsupportable with NSS, and
- hasn't been needed since Tor 0.3.0.1-alpha. Closes ticket 27286.
- o Minor features (geoip):

- version strings, which the C implementation would choke on, e.g.
- "Desc=1\t,2". Fixes bug 27177; bugfix on 0.3.3.5-rc.
- - Protover parsing was ignoring a 2nd hyphen and everything after
- it, accepting entries like "Link=1-5-foo". Fixes bug 27164; bugfix
- on 0.3.3.1-alpha.

- - cd to ${abs_top_builddir}/src/rust before running cargo in
- src/test/test_rust.sh. This makes the working directory consistent
- between builds and tests. Fixes bug 26497; bugfix on 0.3.3.2-alpha.

- - When running make test-network-all, use the mixed+hs-v2 network.
- (A previous fix to chutney removed v3 onion services from the
- mixed+hs-v23 network, so seeing "mixed+hs-v23" in tests is
- confusing.) Fixes bug 27345; bugfix on 0.3.2.1-alpha.
- - Before running make test-network-all, delete old logs and test
- result files, to avoid spurious failures. Fixes bug 27295; bugfix
- on 0.2.7.3-rc.
- o Minor bugfixes (testing, openssl compatibility, backport from 0.3.4.7-rc):
- - Our "tortls/cert_matches_key" unit test no longer relies on

- Changes in version 0.3.4.8 - 2018-09-10
- Tor 0.3.4.8 is the first stable release in its series; it includes
- compilation and portability fixes.
- The Tor 0.3.4 series includes improvements for running Tor in
- low-power and embedded environments, which should help performance in
- general. We've begun work on better modularity, and included preliminary
- changes on the directory authority side to accommodate a new bandwidth
- measurement system. We've also integrated more continuous-integration
- systems into our development process, and made corresponding changes to
- Tor's testing infrastructure. Finally, we've continued to refine
- our anti-denial-of-service code.
- Below are the changes since 0.3.4.7-rc. For a complete list of changes
- since 0.3.3.9, see the ReleaseNotes file.
- o Minor features (compatibility):
- - Tell OpenSSL to maintain backward compatibility with previous
- RSA1024/DH1024 users in Tor. With OpenSSL 1.1.1-pre6, these
- ciphers are disabled by default. Closes ticket 27344.
- o Minor features (continuous integration):
- - Log the compiler path and version during Appveyor builds.
- Implements ticket 27449.

- bugfix on 0.2.3.11-alpha.
- - Stop calling SetProcessDEPPolicy() on 64-bit Windows. It is not
- supported, and always fails. Some compilers warn about the
- function pointer cast on 64-bit Windows. Fixes bug 27461; bugfix
- on 0.2.2.23-alpha.
- o Minor bugfixes (continuous integration):
- - Disable gcc hardening in Appveyor Windows 64-bit builds. As of
- August 29 2018, Appveyor images come with gcc 8.2.0 by default.
- Executables compiled for 64-bit Windows with this version of gcc
- crash when Tor's --enable-gcc-hardening flag is set. Fixes bug
- 27460; bugfix on 0.3.4.1-alpha.
- - When a Travis build fails, and showing a log fails, keep trying to
- show the other logs. Fixes bug 27453; bugfix on 0.3.4.7-rc.

- Changes in version 0.3.4.7-rc - 2018-08-24
- Tor 0.3.4.7-rc fixes several small compilation, portability, and
- correctness issues in previous versions of Tor. This version is a
- release candidate: if no serious bugs are found, we expect that the
- stable 0.3.4 release will be (almost) the same as this release.
- o Minor features (bug workaround):
- - Compile correctly on systems that provide the C11 stdatomic.h
- header, but where C11 atomic functions don't actually compile.

- o Minor bugfixes (testing, openssl compatibility):
- - Our "tortls/cert_matches_key" unit test no longer relies on

- release candidate: if no serious bugs are found, we expect that the
- stable 0.3.4 release will be (almost) the same as this release.
- o Major bugfixes (event scheduler):
- - When we enable a periodic event, schedule it in the event loop
- rather than running it immediately. Previously, we would re-run
- periodic events immediately in the middle of (for example)
- changing our options, with unpredictable effects. Fixes bug 27003;
- bugfix on 0.3.4.1-alpha.
- o Minor features (compilation):

- - The "Bifroest" bridge authority has been retired; the new bridge
- authority is "Serge", and it is operated by George from the
- TorBSD project. Closes ticket 26771.

- o Minor features (sandbox, backport from 0.3.3.4-alpha):
- - 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 feature (continuous integration, backport from 0.3.3.5-rc):
- - 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"

- Country database. Closes ticket 26674.
- 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 (Linux seccomp2 sandbox, backport from 0.3.4.1-alpha):
- - Allow the nanosleep() system call, which glibc uses to implement

- o Minor bugfixes (testing, compatibility, backport from 0.3.4.4-rc):
- - When running the hs_ntor_ref.py test, make sure only to pass
- strings (rather than "bytes" objects) to the Python subprocess
- module. Python 3 on Windows seems to require this. Fixes bug
- 26535; bugfix on 0.3.1.1-alpha.
- - When running the ntor_ref.py test, make sure only to pass strings

- Python 3 on Windows seems to require this. Fixes bug 26535; bugfix
- on 0.2.5.5-alpha.
- o Minor bugfixes (compatibility, openssl, backport from 0.3.4.2-alpha):
- - Work around a change in OpenSSL 1.1.1 where return values that
- would previously indicate "no password" now indicate an empty
- password. Without this workaround, Tor instances running with
- OpenSSL 1.1.1 would accept descriptors that other Tor instances
- would reject. Fixes bug 26116; bugfix on 0.2.5.16.
- o Minor bugfixes (documentation, backport from 0.3.3.5-rc):
- - 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 (compilation, backport from 0.3.4.4-rc):
- - Fix a compilation warning on some versions of GCC when building
- code that calls routerinfo_get_my_routerinfo() twice, assuming
- that the second call will succeed if the first one did. Fixes bug
- 26269; bugfix on 0.2.8.2-alpha.
- 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 (hardening, backport from 0.3.4.2-alpha):
- - Prevent a possible out-of-bounds smartlist read in
- protover_compute_vote(). Fixes bug 26196; bugfix on 0.2.9.4-alpha.
- o Minor bugfixes (C correctness, backport from 0.3.3.4-alpha):
- - 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 (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 (relay, backport from 0.3.4.3-alpha):
- - Relays now correctly block attempts to re-extend to the previous
- relay by Ed25519 identity. Previously they would warn in this
- case, but not actually reject the attempt. Fixes bug 26158; bugfix
- on 0.3.0.1-alpha.
- o Minor bugfixes (relay, crash, backport from 0.3.4.1-alpha):
- - Avoid a crash when running with DirPort set but ORPort turned off.
- Fixes a case of bug 23693; bugfix on 0.3.1.1-alpha.
- o Minor bugfixes (compilation, backport from 0.3.4.2-alpha):
- - Silence unused-const-variable warnings in zstd.h with some GCC
- versions. Fixes bug 26272; bugfix on 0.3.1.1-alpha.
- o Minor bugfixes (testing, backport from 0.3.3.4-alpha):
- - 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.
- o Minor bugfixes (compilation, backport from 0.3.3.4-alpha):
- - 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 (memory, correctness, backport from 0.3.4.4-rc):
- - Fix a number of small memory leaks identified by coverity. Fixes
- bug 26467; bugfix on numerous Tor versions.
- o Code simplification and refactoring (backport from 0.3.3.5-rc):
- - Move the list of default directory authorities to its own file.
- Closes ticket 24854. Patch by "beastr0".
- Changes in version 0.2.9.16 - 2018-07-13
- Tor 0.2.9.16 moves to a new bridge authority, meaning people running
- bridge relays should upgrade. We also take this opportunity to backport
- other minor fixes.
- o Directory authority changes:
- - The "Bifroest" bridge authority has been retired; the new bridge
- authority is "Serge", and it is operated by George from the
- TorBSD project.
