+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.
+ - Install libcap-dev and libseccomp2-dev so these optional
+ 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 0.3.4.6-rc):
+ - When compiling with --enable-openbsd-malloc or --enable-tcmalloc,
+ tell the compiler not to include the system malloc implementation.
+ Fixes bug 20424; bugfix on 0.2.0.20-rc.
+
+ 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
+ function pointer cast on 64-bit Windows. Fixes bug 27461; bugfix
+ 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
+ the underlying issue in bug 26076 is resolved. Fixes bug 26830 and
+ 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
+ rend_client_send_introduction(). Fixes bug 27463; bugfix
+ on 0.1.1.2-alpha.
+
+ o Minor bugfixes (single onion services, Tor2web, backport from 0.3.4.6-rc):
+ - Log a protocol warning when single onion services or Tor2web clients
+ fail to authenticate direct connections to relays.
+ Fixes bug 26924; bugfix on 0.2.9.1-alpha.
+
+ o Minor bugfixes (testing, backport from 0.3.4.6-rc):
+ - Disable core dumps in test_bt.sh, to avoid failures in "make
+ distcheck". Fixes bug 26787; bugfix on 0.2.5.2-alpha.
+
+ o Minor bugfixes (testing, chutney, backport from 0.3.4.8):
+ - 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
+ OpenSSL internals. Previously, it relied on unsupported OpenSSL
+ behavior in a way that caused it to crash with OpenSSL 1.0.2p.
+ Fixes bug 27226; bugfix on 0.2.5.1-alpha.
+
+ o Minor bugfixes (Windows, compilation, backport from 0.3.4.7-rc):
+ - Silence a compilation warning on MSVC 2017 and clang-cl. Fixes bug
+ 27185; bugfix on 0.2.2.2-alpha.

+ ExtOrPorts via GETINFO net/listeners/httptunnel and
+ 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

+
+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.
+ - Show config.log and test-suite.log after failed Appveyor builds.
+ Also upload the zipped full logs as a build artifact. Implements
+ ticket 27430.
+
+ o Minor bugfixes (compilation):
+ - 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.

+
+ 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.

+ 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.

+
+ o Minor bugfixes (testing, chutney):
+ - 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.

+
+ o Minor features (directory authorities, backport from 0.3.4.7-rc):

+ o Minor bugfixes (Windows, compilation, backport from 0.3.4.7-rc):
+ - Silence a compilation warning on MSVC 2017 and clang-cl. Fixes bug
+ 27185; bugfix on 0.2.2.2-alpha.
+
+
+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 0.3.3.9. For a list of only the changes
+ since 0.3.4.7-rc, see the ChangeLog file.
+
+ o New system requirements:
+ - Tor no longer tries to support old operating systems without
+ mmap() or some local equivalent. Apparently, compilation on such
+ systems has been broken for some time, without anybody noticing or
+ complaining. Closes ticket 25398.
+
+ o Major features (directory authority, modularization):
+ - The directory authority subsystem has been modularized. The code
+ is now located in src/or/dirauth/, and is compiled in by default.
+ To disable the module, the configure option
+ --disable-module-dirauth has been added. This module may be
+ disabled by default in some future release. Closes ticket 25610.
+
+ o Major features (main loop, CPU usage):
+ - When Tor is disabled (via DisableNetwork or via hibernation), it
+ no longer needs to run any per-second events. This change should
+ make it easier for mobile applications to disable Tor while the
+ device is sleeping, or Tor is not running. Closes ticket 26063.
+ - Tor no longer enables all of its periodic events by default.
+ Previously, Tor would enable all possible main loop events,
+ regardless of whether it needed them. Furthermore, many of these
+ events are now disabled when Tor is hibernating or DisableNetwork
+ is set. This is a big step towards reducing client CPU usage by
+ reducing the amount of wake-ups the daemon does. Closes tickets
+ 25376 and 25762.
+ - The bandwidth-limitation logic has been refactored so that
+ bandwidth calculations are performed on-demand, rather than every
+ TokenBucketRefillInterval milliseconds. This change should improve
+ the granularity of our bandwidth calculations, and limit the
+ number of times that the Tor process needs to wake up when it is
+ idle. Closes ticket 25373.
+ - Move responsibility for many operations from a once-per-second
+ callback to a callback that is only scheduled as needed. Moving
+ this functionality has allowed us to disable the callback when
+ Tor's network is disabled. Once enough items are removed from our
+ once-per-second callback, we can eliminate it entirely to conserve
+ CPU when idle. The functionality removed includes: closing
+ connections, circuits, and channels (ticket 25932); consensus
+ voting (25937); flushing log callbacks (25951); honoring delayed
+ SIGNEWNYM requests (25949); rescanning the consensus cache
+ (25931); saving the state file to disk (25948); warning relay
+ operators about unreachable ports (25952); and keeping track of
+ Tor's uptime (26009).
+
+ o Minor features (accounting):
+ - When Tor becomes dormant, it now uses a scheduled event to wake up
+ at the right time. Previously, we would use the per-second timer
+ to check whether to wake up, but we no longer have any per-second
+ timers enabled when the network is disabled. Closes ticket 26064.
+
+ 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.
+ Closes ticket 26779; workaround for Debian issue 903709.
+
+ o Minor features (code quality):
+ - Add optional spell-checking for the Tor codebase, using the
+ "misspell" program. To use this feature, run "make check-typos".
+ Closes ticket 25024.
+
+ 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.
+ - Tor now detects versions of OpenSSL 1.1.0 and later compiled with
+ the no-deprecated option, and builds correctly with them. Closes
+ tickets 19429, 19981, and 25353.
+
+ o Minor features (compilation):
+ - When compiling with --enable-openbsd-malloc or --enable-tcmalloc,
+ tell the compiler not to include the system malloc implementation.
+ Fixes bug 20424; bugfix on 0.2.0.20-rc.
+ - Don't try to use a pragma to temporarily disable the
+ -Wunused-const-variable warning if the compiler doesn't support
+ it. Fixes bug 26785; bugfix on 0.3.2.11.
+ - When building Tor, prefer to use Python 3 over Python 2, and more
+ recent (contemplated) versions over older ones. Closes
+ ticket 26372.
+
+ o Minor features (compression, zstd):
+ - When running with zstd, Tor now considers using advanced functions
+ that the zstd maintainers have labeled as potentially unstable. To
+ prevent breakage, Tor will only use this functionality when the
+ runtime version of the zstd library matches the version with which
+ Tor was compiled. Closes ticket 25162.
+
+ o Minor features (configuration):
+ - The "DownloadSchedule" options have been renamed to end with
+ "DownloadInitialDelay". The old names are still allowed, but will
+ produce a warning. Comma-separated lists are still permitted for
+ these options, but all values after the first are ignored (as they
+ have been since 0.2.9). Closes ticket 23354.
+
+ o Minor features (continuous integration):
+ - Log the compiler path and version during Appveyor builds.
+ Implements ticket 27449.
+ - Show config.log and test-suite.log after failed Appveyor builds.
+ Also upload the zipped full logs as a build artifact. Implements
+ ticket 27430.
+ - Backport Travis rust distcheck to 0.3.3. Closes ticket 24629.
+ - Enable macOS builds in our Travis CI configuration. Closes
+ ticket 24629.
+ - Install libcap-dev and libseccomp2-dev so these optional
+ dependencies get tested on Travis CI. Closes ticket 26560.
+ - Only post Appveyor IRC notifications when the build fails.
+ Implements ticket 27275.
+ - Run asciidoc during Travis CI. Implements ticket 27087.
+ - Use ccache in our Travis CI configuration. Closes ticket 26952.
+ - Add the necessary configuration files for continuous integration
+ testing on Windows, via the Appveyor platform. Closes ticket
+ 25549. Patches from Marcin Cieślak and Isis Lovecruft.
+
+ o Minor features (continuous integration, rust):
+ - Use cargo cache in our Travis CI configuration. Closes
+ ticket 26952.
+
+ o Minor features (control port):
+ - Introduce GETINFO "current-time/{local,utc}" to return the local
+ and UTC times respectively in ISO format. This helps a controller
+ like Tor Browser detect a time-related error. Closes ticket 25511.
+ Patch by Neel Chauhan.
+ - Introduce new fields to the CIRC_BW event. There are two new
+ fields in each of the read and written directions. The DELIVERED
+ fields report the total valid data on the circuit, as measured by
+ the payload sizes of verified and error-checked relay command
+ cells. The OVERHEAD fields report the total unused bytes in each
+ of these cells. Closes ticket 25903.
+
+ o Minor features (controller):
+ - The control port now exposes the list of HTTPTunnelPorts and
+ ExtOrPorts via GETINFO net/listeners/httptunnel and
+ net/listeners/extor respectively. Closes ticket 26647.
+
+ o Minor features (directory authorities):
+ - Stop warning about incomplete bw lines before the first complete
+ bw line has been found, so that additional header lines can be
+ ignored. Fixes bug 25960; bugfix on 0.2.2.1-alpha
+ - 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 (directory authority):
+ - Directory authorities now open their key-pinning files as O_SYNC,
+ to limit their chances of accidentally writing partial lines.
+ Closes ticket 23909.
+
+ o Minor features (directory authority, forward compatibility):
+ - Make the lines of the measured bandwidth file able to contain
+ their entries in any order. Previously, the node_id entry needed
+ to come first. Closes ticket 26004.
+
+ o Minor features (entry guards):
+ - Introduce a new torrc option NumPrimaryGuards for controlling the
+ number of primary guards. Closes ticket 25843.
+
+ o Minor features (geoip):
+ - Update geoip and geoip6 to the August 7 2018 Maxmind GeoLite2
+ Country database. Closes ticket 27089.
+
+ o Minor features (performance):
+ - Avoid a needless call to malloc() when processing an incoming
+ relay cell. Closes ticket 24914.
+ - Make our timing-wheel code run a tiny bit faster on 32-bit
+ platforms, by preferring 32-bit math to 64-bit. Closes
+ ticket 24688.
+ - Avoid a needless malloc()/free() pair every time we handle an ntor
+ handshake. Closes ticket 25150.
+
+ o Minor features (Rust, portability):
+ - Rust cross-compilation is now supported. Closes ticket 25895.
+
+ o Minor features (testing):
+ - Add a unit test for voting_schedule_get_start_of_next_interval().
+ Closes ticket 26014, and helps make unit test coverage
+ more deterministic.
+ - A new unittests module specifically for testing the functions in
+ the (new-ish) bridges.c module has been created with new
+ unittests, raising the code coverage percentages. Closes 25425.
+ - We now have improved testing for addressmap_get_virtual_address()
+ function. This should improve our test coverage, and make our test
+ coverage more deterministic. Closes ticket 25993.
+
+ o Minor features (timekeeping, circuit scheduling):
+ - When keeping track of how busy each circuit have been recently on
+ a given connection, use coarse-grained monotonic timers rather
+ than gettimeofday(). This change should marginally increase
+ accuracy and performance. Implements part of ticket 25927.
+
+ o Minor features (unit tests):
+ - Test complete bandwidth measurements files, and test that
+ incomplete bandwidth lines only give warnings when the end of the
+ header has not been detected. Fixes bug 25947; bugfix
+ on 0.2.2.1-alpha
+
+ o Minor bugfixes (bandwidth management):
+ - Consider ourselves "low on write bandwidth" if we have exhausted
+ our write bandwidth some time in the last second. This was the
+ documented behavior before, but the actual behavior was to change
+ this value every TokenBucketRefillInterval. Fixes bug 25828;
+ bugfix on 0.2.3.5-alpha.
+
+ o Minor bugfixes (C correctness):
+ - Add a missing lock acquisition in the shutdown code of the control
+ subsystem. Fixes bug 25675; bugfix on 0.2.7.3-rc. Found by
+ Coverity; this is CID 1433643.
+
+ o Minor bugfixes (code style):
+ - Fixed multiple includes of transports.h in src/or/connection.c
+ Fixes bug 25261; bugfix on 0.2.5.1-alpha.
+ - Remove the unused variable n_possible from the function
+ channel_get_for_extend(). Fixes bug 25645; bugfix on 0.2.4.4-alpha
+
+ o Minor bugfixes (compilation):
+ - 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
+ function pointer cast on 64-bit Windows. Fixes bug 27461; bugfix
+ on 0.2.2.23-alpha.
+ - 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.
+ - Refrain from compiling unit testing related object files when
+ --disable-unittests is set to configure script. Fixes bug 24891;
+ bugfix on 0.2.5.1-alpha.
+ - The --enable-fatal-warnings flag now affects Rust code as well.
+ Closes ticket 26245.
+ - Avoid a compiler warning when casting the return value of
+ smartlist_len() to double with DEBUG_SMARTLIST enabled. Fixes bug
+ 26283; bugfix on 0.2.4.10-alpha.
+
+ o Minor bugfixes (compilation, windows):
+ - 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):
+ - Build with zstd on macOS. Fixes bug 27090; bugfix on 0.3.1.5-alpha.
+ - Skip a pair of unreliable key generation tests on Windows, until
+ the underlying issue in bug 26076 is resolved. Fixes bug 26830 and
+ bug 26853; bugfix on 0.2.7.3-rc and 0.3.2.1-alpha respectively.
+
+ o Minor bugfixes (control port):
+ - Respond with more human-readable error messages to GETINFO exit-
+ policy/* requests. Also, let controller know if an error is
+ transient (response code 551) or not (response code 552). Fixes
+ bug 25852; bugfix on 0.2.8.1-alpha.
+ - Parse the "HSADDRESS=" parameter in HSPOST commands properly.
+ Previously, it was misparsed and ignored. Fixes bug 26523; bugfix
+ on 0.3.3.1-alpha. Patch by "akwizgran".
+ - Make CIRC_BW event reflect the total of all data sent on a
+ circuit, including padding and dropped cells. Also fix a mis-
+ counting bug when STREAM_BW events were enabled. Fixes bug 25400;
+ bugfix on 0.2.5.2-alpha.
+
+ o Minor bugfixes (correctness, flow control):
+ - Upon receiving a stream-level SENDME cell, verify that our window
+ has not grown too large. Fixes bug 26214; bugfix on svn
+ r54 (pre-0.0.1)
+
+ o Minor bugfixes (directory authority):
+ - 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 (directory client):
+ - When unverified-consensus is verified, rename it to cached-
+ consenus. Fixes bug 4187; bugfix on 0.2.0.3-alpha.
+ - Fixed launching a certificate fetch always during the scheduled
+ periodic consensus fetch by fetching only in those cases when
+ consensus are waiting for certs. Fixes bug 24740; bugfix
+ on 0.2.9.1-alpha.
+
+ o Minor bugfixes (error reporting):
+ - Improve tolerance for directory authorities with skewed clocks.
+ Previously, an authority with a clock more than 60 seconds ahead
+ could cause a client with a correct clock to warn that the
+ client's clock was behind. Now the clocks of a majority of
+ directory authorities have to be ahead of the client before this
+ warning will occur. Fixes bug 25756; bugfix on 0.2.2.25-alpha.
+
+ o Minor bugfixes (in-process restart):
+ - Always call tor_free_all() when leaving tor_run_main(). When we
+ did not, restarting tor in-process would cause an assertion
+ failure. Fixes bug 26948; bugfix on 0.3.3.1-alpha.
+
+ o Minor bugfixes (Linux seccomp2 sandbox):
+ - Fix a bug in our 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 (logging):
+ - Improve the log message when connection initiators fail to
+ authenticate direct connections to relays. Fixes bug 26927; bugfix
+ on 0.3.0.1-alpha.
+
+ o Minor bugfixes (onion services):
+ - Silence a spurious compiler warning in
+ rend_client_send_introduction(). Fixes bug 27463; bugfix
+ on 0.1.1.2-alpha.
+ - Fix bug that causes services to not ever rotate their descriptors
+ if they were getting SIGHUPed often. Fixes bug 26932; bugfix
+ on 0.3.2.1-alpha.
+ - Recompute some consensus information after detecting a clock jump,
+ or after transitioning from a non-live consensus to a live
+ consensus. We do this to avoid having an outdated state, and
+ miscalculating the index for next-generation onion services. Fixes
+ bug 24977; bugfix on 0.3.2.1-alpha.
+
+ o Minor bugfixes (portability):
+ - Fix compilation of the unit tests on GNU/Hurd, which does not
+ define PATH_MAX. Fixes bug 26873; bugfix on 0.3.3.1-alpha. Patch
+ from "paulusASol".
+ - Work around two different bugs in the OS X 10.10 and later SDKs
+ that would prevent us from successfully targeting earlier versions
+ of OS X. Fixes bug 26876; bugfix on 0.3.3.1-alpha.
+ - Do not align mmap length, as it is not required by POSIX, and the
+ getpagesize function is deprecated. Fixes bug 25399; bugfix
+ on 0.1.1.23.
+
+ o Minor bugfixes (portability, FreeBSD):
+ - In have_enough_mem_for_dircache(), the variable DIRCACHE_MIN_MEM_MB
+ does not stringify on FreeBSD, so we switch to tor_asprintf().
+ Fixes bug 20887; bugfix on 0.2.8.1-alpha. Patch by Neel Chauhan.
+
+ o Minor bugfixes (relay statistics):
+ - When a relay is collecting internal statistics about how many
+ create cell requests it has seen of each type, accurately count
+ the requests from relays that temporarily fall out of the
+ consensus. (To be extra conservative, we were already ignoring
+ requests from clients in our counts, and we continue ignoring them
+ here.) Fixes bug 24910; bugfix on 0.2.4.17-rc.
+
+ o Minor bugfixes (rust):
+ - Backport test_rust.sh from master. Fixes bug 26497; bugfix
+ on 0.3.1.5-alpha.
+ - Protover parsing was accepting the presence of whitespace in
+ 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.
+ - Stop setting $CARGO_HOME. cargo will use the user's $CARGO_HOME, or
+ $HOME/.cargo by default. Fixes bug 26497; bugfix on 0.3.1.5-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.
+
+ o Minor bugfixes (single onion services, Tor2web):
+ - Log a protocol warning when single onion services or Tor2web
+ clients fail to authenticate direct connections to relays. Fixes
+ bug 26924; bugfix on 0.2.9.1-alpha.
+
+ o Minor bugfixes (test coverage tools):
+ - Update our "cov-diff" script to handle output from the latest
+ version of gcov, and to remove extraneous timestamp information
+ from its output. Fixes bugs 26101 and 26102; bugfix
+ on 0.2.5.1-alpha.
+
+ o Minor bugfixes (testing):
+ - Disable core dumps in test_bt.sh, to avoid failures in "make
+ distcheck". Fixes bug 26787; bugfix on 0.2.5.2-alpha.
+ - When testing workqueue event-cancellation, make sure that we
+ actually cancel an event, and that cancel each event with equal
+ probability. (It was previously possible, though extremely
+ unlikely, for our event-canceling test not to cancel any events.)
+ Fixes bug 26008; bugfix on 0.2.6.3-alpha.
+ - Repeat part of the test in test_client_pick_intro() a number of
+ times, to give it consistent coverage. Fixes bug 25996; bugfix
+ on 0.3.2.1-alpha.
+ - Remove randomness from the hs_common/responsible_hsdirs test, so
+ that it always takes the same path through the function it tests.
+ Fixes bug 25997; bugfix on 0.3.2.1-alpha.
+ - Change the behavior of the "channel/outbound" test so that it
+ never causes a 10-second rollover for the EWMA circuitmux code.
+ Previously, this behavior would happen randomly, and result in
+ fluctuating test coverage. Fixes bug 25994; bugfix
+ on 0.3.3.1-alpha.
+ - Use X509_new() to allocate certificates that will be freed later
+ with X509_free(). Previously, some parts of the unit tests had
+ used tor_malloc_zero(), which is incorrect, and which caused test
+ failures on Windows when they were built with extra hardening.
+ Fixes bugs 25943 and 25944; bugfix on 0.2.8.1-alpha. Patch by
+ Marcin Cieślak.
+ - While running the circuit_timeout test, fix the PRNG to a
+ deterministic AES stream, so that the test coverage from this test
+ will itself be deterministic. Fixes bug 25995; bugfix
+ on 0.2.2.2-alpha.
+
+ o Minor bugfixes (testing, bootstrap):
+ - When calculating bootstrap progress, check exit policies and the
+ exit flag. Previously, Tor would only check the exit flag, which
+ caused race conditions in small and fast networks like chutney.
+ Fixes bug 27236; bugfix on 0.2.6.3-alpha.
+
+ o Minor bugfixes (testing, chutney):
+ - 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):
+ - Our "tortls/cert_matches_key" unit test no longer relies on
+ OpenSSL internals. Previously, it relied on unsupported OpenSSL
+ behavior in a way that caused it to crash with OpenSSL 1.0.2p.
+ Fixes bug 27226; bugfix on 0.2.5.1-alpha.
+
+ o Minor bugfixes (v3 onion services):
+ - Stop sending ed25519 link specifiers in v3 onion service introduce
+ cells and descriptors, when the rendezvous or introduction point
+ doesn't support ed25519 link authentication. Fixes bug 26627;
+ bugfix on 0.3.2.4-alpha.
+
+ o Minor bugfixes (vanguards):
+ - Allow the last hop in a vanguard circuit to be the same as our
+ first, to prevent the adversary from influencing guard node choice
+ by choice of last hop. Also prevent the creation of A - B - A
+ paths, or A - A paths, which are forbidden by relays. Fixes bug
+ 25870; bugfix on 0.3.3.1-alpha.
+
+ o Minor bugfixes (Windows, compilation):
+ - Silence a compilation warning on MSVC 2017 and clang-cl. Fixes bug
+ 27185; bugfix on 0.2.2.2-alpha.
+
+ o Code simplification and refactoring:
+ - Remove duplicate code in parse_{c,s}method_line and bootstrap
+ their functionalities into a single function. Fixes bug 6236;
+ bugfix on 0.2.3.6-alpha.
+ - We remove the PortForwsrding and PortForwardingHelper options,
+ related functions, and the port_forwarding tests. These options
+ were used by the now-deprecated Vidalia to help ordinary users
+ become Tor relays or bridges. Closes ticket 25409. Patch by
+ Neel Chauhan.
+ - In order to make the OR and dir checking function in router.c less
+ confusing we renamed some functions and
+ consider_testing_reachability() has been split into
+ router_should_check_reachability() and
+ router_do_reachability_checks(). Also we improved the documentation
+ in some functions. Closes ticket 18918.
+ - Initial work to isolate Libevent usage to a handful of modules in
+ our codebase, to simplify our call structure, and so that we can
+ more easily change event loops in the future if needed. Closes
+ ticket 23750.
+ - Introduce a function to call getsockname() and return tor_addr_t,
+ to save a little complexity throughout the codebase. Closes
+ ticket 18105.
+ - Make hsdir_index in node_t a hsdir_index_t rather than a pointer
+ as hsdir_index is always present. Also, we move hsdir_index_t into
+ or.h. Closes ticket 23094. Patch by Neel Chauhan.
+ - Merge functions used for describing nodes and suppress the
+ functions that do not allocate memory for the output buffer
+ string. NODE_DESC_BUF_LEN constant and format_node_description()
+ function cannot be used externally from router.c module anymore.
+ Closes ticket 25432. Patch by valentecaio.
+ - Our main loop has been simplified so that all important operations
+ happen inside events. Previously, some operations had to happen
+ outside the event loop, to prevent infinite sequences of event
+ activations. Closes ticket 25374.
+ - Put a SHA1 public key digest in hs_service_intro_point_t, and use
+ it in register_intro_circ() and service_intro_point_new(). This
+ prevents the digest from being re-calculated each time. Closes
+ ticket 23107. Patch by Neel Chauhan.
+ - Refactor token-bucket implementations to use a common backend.
+ Closes ticket 25766.
+ - Remove extern declaration of stats_n_seconds_working variable from
+ main, protecting its accesses with get_uptime() and reset_uptime()
+ functions. Closes ticket 25081, patch by “valentecaio”.
+ - Remove our previous logic for "cached gettimeofday()" -- our
+ coarse monotonic timers are fast enough for this purpose, and far
+ less error-prone. Implements part of ticket 25927.
+ - Remove the return value for fascist_firewall_choose_address_base(),
+ and sister functions such as fascist_firewall_choose_address_node()
+ and fascist_firewall_choose_address_rs(). Also, while we're here,
+ initialize the ap argument as leaving it uninitialized can pose a
+ security hazard. Closes ticket 24734. Patch by Neel Chauhan.
+ - Rename two fields of connection_t struct. timestamp_lastwritten is
+ renamed to timestamp_last_write_allowed and timestamp_lastread is
+ renamed to timestamp_last_read_allowed. Closes ticket 24714, patch
+ by "valentecaio".
+ - Since Tor requires C99, remove our old workaround code for libc
+ implementations where free(NULL) doesn't work. Closes ticket 24484.
+ - Use our standard rate-limiting code to deal with excessive
+ libevent failures, rather than the hand-rolled logic we had
+ before. Closes ticket 26016.
+ - We remove the return value of node_get_prim_orport() and
+ node_get_prim_dirport(), and introduce node_get_prim_orport() in
+ node_ipv6_or_preferred() and node_ipv6_dir_preferred() in order to
+ check for a null address. Closes ticket 23873. Patch by
+ Neel Chauhan.
+ - We switch to should_record_bridge_info() in
+ geoip_note_client_seen() and options_need_geoip_info() instead of
+ accessing the configuration values directly. Fixes bug 25290;
+ bugfix on 0.2.1.6-alpha. Patch by Neel Chauhan.
+
+ o Deprecated features:
+ - As we are not recommending 0.2.5 anymore, we require relays that
+ once had an ed25519 key associated with their RSA key to always
+ have that key, instead of allowing them to drop back to a version
+ that didn't support ed25519. This means they need to use a new RSA
+ key if the want to downgrade to an older version of tor without
+ ed25519. Closes ticket 20522.
+
+ o Removed features:
+ - Directory authorities will no longer support voting according to
+ any consensus method before consensus method 25. This keeps
+ authorities compatible with all authorities running 0.2.9.8 and
+ later, and does not break any clients or relays. Implements ticket
+ 24378 and proposal 290.
+ - The PortForwarding and PortForwardingHelper features have been
+ removed. The reasoning is, given that implementations of NAT
+ traversal protocols within common consumer grade routers are
+ frequently buggy, and that the target audience for a NAT punching
+ feature is a perhaps less-technically-inclined relay operator,
+ when the helper fails to setup traversal the problems are usually
+ deep, ugly, and very router specific, making them horrendously
+ impossible for technical support to reliable assist with, and thus
+ resulting in frustration all around. Unfortunately, relay
+ operators who would like to run relays behind NATs will need to
+ become more familiar with the port forwarding configurations on
+ their local router. Closes 25409.
+ - The TestingEnableTbEmptyEvent option has been removed. It was used
+ in testing simulations to measure how often connection buckets
+ were emptied, in order to improve our scheduling, but it has not
+ been actively used in years. Closes ticket 25760.
+ - The old "round-robin" circuit multiplexer (circuitmux)
+ implementation has been removed, along with a fairly large set of
+ code that existed to support it. It has not been the default
+ circuitmux since we introduced the "EWMA" circuitmux in 0.2.4.x,
+ but it still required an unreasonable amount of memory and CPU.
+ Closes ticket 25268.

Changes in version 0.3.3.9 - 2018-07-13
Tor 0.3.3.9 moves to a new bridge authority, meaning people running
bridge relays should upgrade.
