This series + improves reliability and stability, and includes several stability and + correctness improvements for onion services. It also fixes many smaller + bugs present in previous series. + + Per our support policy, we will support the 0.4.2.x series for nine + months, or until three months after the release of a stable 0.4.3.x: + whichever is longer. If you need longer-term support, please stick + with 0.3.5.x, which will we plan to support until Feb 2022. + + Per our support policy, we will support the 0.4.2.x series for nine + months, or until three months after the release of a stable 0.4.3.x: + whichever is longer.

For a complete list of changes + since 0.4.1.5, see the ReleaseNotes file. + + o Minor features (geoip): + - Update geoip and geoip6 to the December 3 2019 Maxmind GeoLite2 + Country database. Closes ticket 32685. + + o Testing: + - Require C99 standards-conforming code in Travis CI, but allow GNU + gcc extensions. Also activates clang's -Wtypedef-redefinition + warnings. Build some jobs with -std=gnu99, and some jobs without. + Closes ticket 32500. + + +Changes in version 0.4.1.7 - 2019-12-09 + This release backports several bugfixes to improve stability and + correctness. Anyone experiencing build problems or crashes with 0.4.1.6, + including all relays relying on AccountingMax, should upgrade. + + o Major features (directory authorities, backport from 0.4.2.2-alpha): + - Directory authorities now reject relays running all currently + deprecated release series. The currently supported release series + are: 0.2.9, 0.3.5, 0.4.0, 0.4.1, and 0.4.2. Closes ticket 31549. + + o Major bugfixes (embedded Tor, backport from 0.4.2.2-alpha): + - Avoid a possible crash when restarting Tor in embedded mode and + enabling a different set of publish/subscribe messages. Fixes bug + 31898; bugfix on 0.4.1.1-alpha. + + o Major bugfixes (relay, backport from 0.4.2.3-alpha): + - Relays now respect their AccountingMax bandwidth again. When + relays entered "soft" hibernation (which typically starts when + we've hit 90% of our AccountingMax), we had stopped checking + whether we should enter hard hibernation. Soft hibernation refuses + new connections and new circuits, but the existing circuits can + continue, meaning that relays could have exceeded their configured + AccountingMax. Fixes bug 32108; bugfix on 0.4.0.1-alpha. + + o Major bugfixes (torrc parsing, backport from 0.4.2.2-alpha): + - Stop ignoring torrc options after an %include directive, when the + included directory ends with a file that does not contain any + config options (but does contain comments or whitespace). Fixes + bug 31408; bugfix on 0.3.1.1-alpha. + + o Major bugfixes (v3 onion services, backport from 0.4.2.3-alpha): + - Onion services now always use the exact number of intro points + configured with the HiddenServiceNumIntroductionPoints option (or + fewer if nodes are excluded). Before, a service could sometimes + pick more intro points than configured. Fixes bug 31548; bugfix + on 0.3.2.1-alpha. + + o Minor features (continuous integration, backport from 0.4.2.2-alpha): + - When building on Appveyor and Travis, pass the "-k" flag to make, + so that we are informed of all compilation failures, not just the + first one or two. Closes ticket 31372. + + o Minor features (geoip, backport from 0.4.2.5): + - Update geoip and geoip6 to the December 3 2019 Maxmind GeoLite2 + Country database. Closes ticket 32685. + + o Minor bugfixes (Appveyor CI, backport from 0.4.2.2-alpha): + - Avoid spurious errors when Appveyor CI fails before the install step. + Fixes bug 31884; bugfix on 0.3.4.2-alpha. + + o Minor bugfixes (client, onion service v3, backport from 0.4.2.4-rc): + - Fix a BUG() assertion that occurs within a very small race window + between when a client intro circuit opens and when its descriptor + gets cleaned up from the cache. The circuit is now closed early, + which will trigger a re-fetch of the descriptor and continue the + connection. Fixes bug 28970; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (connections, backport from 0.4.2.3-rc): + - Avoid trying to read data from closed connections, which can cause + needless loops in Libevent and infinite loops in Shadow. Fixes bug + 30344; bugfix on 0.1.1.1-alpha. + + o Minor bugfixes (error handling, backport from 0.4.2.1-alpha): + - On abort, try harder to flush the output buffers of log messages. + On some platforms (macOS), log messages could be discarded when + the process terminates. Fixes bug 31571; bugfix on 0.3.5.1-alpha. + - Report the tor version whenever an assertion fails. Previously, we + only reported the Tor version on some crashes, and some non-fatal + assertions. Fixes bug 31571; bugfix on 0.3.5.1-alpha. + - When tor aborts due to an error, close log file descriptors before + aborting. Closing the logs makes some OSes flush log file buffers, + rather than deleting buffered log lines. Fixes bug 31594; bugfix + on 0.2.5.2-alpha. + + o Minor bugfixes (logging, backport from 0.4.2.2-alpha): + - Add a missing check for HAVE_PTHREAD_H, because the backtrace code + uses mutexes. Fixes bug 31614; bugfix on 0.2.5.2-alpha. + - Disable backtrace signal handlers when shutting down tor. Fixes + bug 31614; bugfix on 0.2.5.2-alpha. + - Rate-limit our the logging message about the obsolete .exit + notation. Previously, there was no limit on this warning, which + could potentially be triggered many times by a hostile website. + Fixes bug 31466; bugfix on 0.2.2.1-alpha. + + o Minor bugfixes (logging, protocol violations, backport from 0.4.2.2-alpha): + - Do not log a nonfatal assertion failure when receiving a VERSIONS + cell on a connection using the obsolete v1 link protocol. Log a + protocol_warn instead. Fixes bug 31107; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (mainloop, periodic events, in-process API, backport from 0.4.2.3-alpha): + - Reset the periodic events' "enabled" flag when Tor is shut down + cleanly. Previously, this flag was left on, which caused periodic + events not to be re-enabled when Tor was relaunched in-process + with tor_api.h after a shutdown. Fixes bug 32058; bugfix + on 0.3.3.1-alpha. + + o Minor bugfixes (multithreading, backport from 0.4.2.2-alpha): + - Avoid some undefined behaviour when freeing mutexes. Fixes bug + 31736; bugfix on 0.0.7. + + o Minor bugfixes (process management, backport from 0.4.2.3-alpha): + - Remove overly strict assertions that triggered when a pluggable + transport failed to launch. Fixes bug 31091; bugfix + on 0.4.0.1-alpha. + - Remove an assertion in the Unix process backend. This assertion + would trigger when we failed to find the executable for a child + process. Fixes bug 31810; bugfix on 0.4.0.1-alpha. + + o Minor bugfixes (relay, backport from 0.4.2.2-alpha): + - Avoid crashing when starting with a corrupt keys directory where + the old ntor key and the new ntor key are identical. Fixes bug + 30916; bugfix on 0.2.4.8-alpha. + + o Minor bugfixes (testing, backport from 0.4.2.3-alpha): + - When testing port rebinding, don't busy-wait for tor to log. + Instead, actually sleep for a short time before polling again. + Also improve the formatting of control commands and log messages. + Fixes bug 31837; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (tests, SunOS, backport from 0.4.2.2-alpha): + - Avoid a map_anon_nofork test failure due to a signed/unsigned + integer comparison. Fixes bug 31897; bugfix on 0.4.1.1-alpha. + + o Minor bugfixes (tls, logging, backport from 0.4.2.3-alpha): + - Log bugs about the TLS read buffer's length only once, rather than + filling the logs with similar warnings. Fixes bug 31939; bugfix + on 0.3.0.4-rc. + + o Documentation (backport from 0.4.2.2-alpha): + - Explain why we can't destroy the backtrace buffer mutex. Explain + why we don't need to destroy the log mutex. Closes ticket 31736. + + o Testing (continuous integration, backport from 0.4.2.3-alpha): + - Disable all but one Travis CI macOS build, to mitigate slow + scheduling of Travis macOS jobs. Closes ticket 32177. + - Run the chutney IPv6 networks as part of Travis CI. Closes + ticket 30860. + - Simplify the Travis CI build matrix, and optimise for build time. + Closes ticket 31859. + - Use Windows Server 2019 instead of Windows Server 2016 in our + Appveyor builds. Closes ticket 32086. + + o Testing (continuous integration, backport from 0.4.2.4-rc): + - In Travis, use Xcode 11.2 on macOS 10.14. Closes ticket 32241. + - Use Ubuntu Bionic images for our Travis CI builds, so we can get a + recent version of coccinelle. But leave chutney on Ubuntu Trusty, + until we can fix some Bionic permissions issues (see ticket + 32240). Related to ticket 31919. + - Install the mingw OpenSSL package in Appveyor. This makes sure + that the OpenSSL headers and libraries match in Tor's Appveyor + builds. (This bug was triggered by an Appveyor image update.) + Fixes bug 32449; bugfix on 0.3.5.6-rc. + + o Testing (continuous integration, backport from 0.4.2.5): + - Require C99 standards-conforming code in Travis CI, but allow GNU gcc + extensions. Also activates clang's -Wtypedef-redefinition warnings. + Build some jobs with -std=gnu99, and some jobs without. + Closes ticket 32500. + + +Changes in version 0.4.0.6 - 2019-12-09 + This is the second stable release in the 0.4.0.x series. This release + backports several bugfixes to improve stability and correctness. Anyone + experiencing build problems or crashes with 0.4.0.5, including all relays + relying on AccountingMax, should upgrade. + + Note that, per our support policy, support for the 0.4.0.x series will end + on 2 Feb 2020. Anyone still running 0.4.0.x should plan to upgrade to the + latest stable release, or downgrade to 0.3.5.x, which will get long-term + support until 1 Feb 2022. + + o Directory authority changes (backport from 0.4.1.5): + - The directory authority "dizum" has a new IP address. Closes + ticket 31406. + + o Major bugfixes (bridges, backport from 0.4.1.2-alpha): + - Consider our directory information to have changed when our list + of bridges changes. Previously, Tor would not re-compute the + status of its directory information when bridges changed, and + therefore would not realize that it was no longer able to build + circuits. Fixes part of bug 29875. + - Do not count previously configured working bridges towards our + total of working bridges. Previously, when Tor's list of bridges + changed, it would think that the old bridges were still usable, + and delay fetching router descriptors for the new ones. Fixes part + of bug 29875; bugfix on 0.3.0.1-alpha. + + o Major bugfixes (circuit build, guard, backport from 0.4.1.4-rc): + - When considering upgrading circuits from "waiting for guard" to + "open", always ignore circuits that are marked for close. Otherwise, + we can end up in the situation where a subsystem is notified that + a closing circuit has just opened, leading to undesirable + behavior. Fixes bug 30871; bugfix on 0.3.0.1-alpha. + + o Major bugfixes (Onion service reachability, backport from 0.4.1.3-alpha): + - Properly clean up the introduction point map when circuits change + purpose from onion service circuits to pathbias, measurement, or + other circuit types. This should fix some service-side instances + of introduction point failure. Fixes bug 29034; bugfix + on 0.3.2.1-alpha. + + o Major bugfixes (onion service v3, backport from 0.4.1.1-alpha): + - Fix an unreachable bug in which an introduction point could try to + send an INTRODUCE_ACK with a status code that Trunnel would refuse + to encode, leading the relay to assert(). We've consolidated the + ABI values into Trunnel now. Fixes bug 30454; bugfix + on 0.3.0.1-alpha. + - Clients can now handle unknown status codes from INTRODUCE_ACK + cells. (The NACK behavior will stay the same.) This will allow us + to extend status codes in the future without breaking the normal + client behavior. Fixes another part of bug 30454; bugfix + on 0.3.0.1-alpha. + + o Major bugfixes (relay, backport from 0.4.2.3-alpha): + - Relays now respect their AccountingMax bandwidth again. When + relays entered "soft" hibernation (which typically starts when + we've hit 90% of our AccountingMax), we had stopped checking + whether we should enter hard hibernation. Soft hibernation refuses + new connections and new circuits, but the existing circuits can + continue, meaning that relays could have exceeded their configured + AccountingMax. Fixes bug 32108; bugfix on 0.4.0.1-alpha. + + o Major bugfixes (torrc parsing, backport from 0.4.2.2-alpha): + - Stop ignoring torrc options after an %include directive, when the + included directory ends with a file that does not contain any + config options (but does contain comments or whitespace). Fixes + bug 31408; bugfix on 0.3.1.1-alpha. + + o Major bugfixes (v3 onion services, backport from 0.4.2.3-alpha): + - Onion services now always use the exact number of intro points + configured with the HiddenServiceNumIntroductionPoints option (or + fewer if nodes are excluded). Before, a service could sometimes + pick more intro points than configured. Fixes bug 31548; bugfix + on 0.3.2.1-alpha. + + o Minor features (compile-time modules, backport from version 0.4.1.1-alpha): + - Add a "--list-modules" command to print a list of which compile- + time modules are enabled. Closes ticket 30452. + + o Minor features (continuous integration, backport from 0.4.1.1-alpha): + - Remove sudo configuration lines from .travis.yml as they are no + longer needed with current Travis build environment. Resolves + issue 30213. + + o Minor features (continuous integration, backport from 0.4.1.4-rc): + - Our Travis configuration now uses Chutney to run some network + integration tests automatically. Closes ticket 29280. + + o Minor features (continuous integration, backport from 0.4.2.2-alpha): + - When building on Appveyor and Travis, pass the "-k" flag to make, + so that we are informed of all compilation failures, not just the + first one or two. Closes ticket 31372. + + o Minor features (fallback directory list, backport from 0.4.1.4-rc): + - Replace the 157 fallbacks originally introduced in Tor 0.3.5.6-rc + in December 2018 (of which ~122 were still functional), with a + list of 148 fallbacks (70 new, 78 existing, 79 removed) generated + in June 2019. Closes ticket 28795. + + o Minor features (geoip, backport from 0.4.2.5): + - Update geoip and geoip6 to the December 3 2019 Maxmind GeoLite2 + Country database. Closes ticket 32685. + + o Minor features (stem tests, backport from 0.4.2.1-alpha): + - Change "make test-stem" so it only runs the stem tests that use + tor. This change makes test-stem faster and more reliable. Closes + ticket 31554. + + o Minor bugfixes (Appveyor CI, backport from 0.4.2.2-alpha): + - Avoid spurious errors when Appveyor CI fails before the install step. + Fixes bug 31884; bugfix on 0.3.4.2-alpha. + + o Minor bugfixes (build system, backport form 0.4.2.1-alpha): + - Do not include the deprecated on Linux or Windows + systems. Fixes bug 31673; bugfix on 0.2.5.4-alpha. + + o Minor bugfixes (circuit isolation, backport from 0.4.1.3-alpha): + - Fix a logic error that prevented the SessionGroup sub-option from + being accepted. Fixes bug 22619; bugfix on 0.2.7.2-alpha. + + o Minor bugfixes (circuit padding, backport from 0.4.1.4-rc): + - On relays, properly check that a padding machine is absent before + logging a warning about it being absent. Fixes bug 30649; bugfix + on 0.4.0.1-alpha. + + o Minor bugfixes (client, onion service v3, backport from 0.4.2.4-rc): + - Fix a BUG() assertion that occurs within a very small race window + between when a client intro circuit opens and when its descriptor + gets cleaned up from the cache. The circuit is now closed early, + which will trigger a re-fetch of the descriptor and continue the + connection. Fixes bug 28970; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (clock skew detection, backport from 0.4.1.5): + - Don't believe clock skew results from NETINFO cells that appear to + arrive before we sent the VERSIONS cells they are responding to. + Previously, we would accept them up to 3 minutes "in the past". + Fixes bug 31343; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (compilation warning, backport from 0.4.1.5): + - Fix a compilation warning on Windows about casting a function + pointer for GetTickCount64(). Fixes bug 31374; bugfix + on 0.2.9.1-alpha. + + o Minor bugfixes (compilation, backport from 0.4.1.5): + - Avoid using labs() on time_t, which can cause compilation warnings + on 64-bit Windows builds. Fixes bug 31343; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (compilation, backport from 0.4.2.1-alpha): + - Suppress spurious float-conversion warnings from GCC when calling + floating-point classifier functions on FreeBSD. Fixes part of bug + 31687; bugfix on 0.3.1.5-alpha. + + o Minor bugfixes (compilation, unusual configurations, backport from 0.4.1.1-alpha): + - Avoid failures when building with the ALL_BUGS_ARE_FATAL option + due to missing declarations of abort(), and prevent other such + failures in the future. Fixes bug 30189; bugfix on 0.3.4.1-alpha. + + o Minor bugfixes (configuration, proxies, backport from 0.4.1.2-alpha): + - Fix a bug that prevented us from supporting SOCKS5 proxies that + want authentication along with configured (but unused!) + ClientTransportPlugins. Fixes bug 29670; bugfix on 0.2.6.1-alpha. + + o Minor bugfixes (connections, backport from 0.4.2.3-rc): + - Avoid trying to read data from closed connections, which can cause + needless loops in Libevent and infinite loops in Shadow. Fixes bug + 30344; bugfix on 0.1.1.1-alpha. + + o Minor bugfixes (continuous integration, backport from 0.4.1.3-alpha): + - Allow the test-stem job to fail in Travis, because it sometimes + hangs. Fixes bug 30744; bugfix on 0.3.5.4-alpha. + - Skip test_rebind on macOS in Travis, because it is unreliable on + macOS on Travis. Fixes bug 30713; bugfix on 0.3.5.1-alpha. + - Skip test_rebind when the TOR_SKIP_TEST_REBIND environment + variable is set. Fixes bug 30713; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (crash on exit, backport from 0.4.1.4-rc): + - Avoid a set of possible code paths that could try to use freed + memory in routerlist_free() while Tor was exiting. Fixes bug + 31003; bugfix on 0.1.2.2-alpha. + + o Minor bugfixes (directory authorities, backport from 0.4.1.3-alpha): + - Stop crashing after parsing an unknown descriptor purpose + annotation. We think this bug can only be triggered by modifying a + local file. Fixes bug 30781; bugfix on 0.2.0.8-alpha. + + o Minor bugfixes (directory authority, backport from 0.4.1.2-alpha): + - Move the "bandwidth-file-headers" line in directory authority + votes so that it conforms to dir-spec.txt. Fixes bug 30316; bugfix + on 0.3.5.1-alpha. + + o Minor bugfixes (error handling, backport from 0.4.2.1-alpha): + - On abort, try harder to flush the output buffers of log messages. + On some platforms (macOS), log messages could be discarded when + the process terminates. Fixes bug 31571; bugfix on 0.3.5.1-alpha. + - Report the tor version whenever an assertion fails. Previously, we + only reported the Tor version on some crashes, and some non-fatal + assertions. Fixes bug 31571; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (FreeBSD, PF-based proxy, IPv6, backport from 0.4.2.1-alpha): + - When extracting an IPv6 address from a PF-based proxy, verify that + we are actually configured to receive an IPv6 address, and log an + internal error if not. Fixes part of bug 31687; bugfix + on 0.2.3.4-alpha. + + o Minor bugfixes (guards, backport from 0.4.2.1-alpha): + - When tor is missing descriptors for some primary entry guards, + make the log message less alarming. It's normal for descriptors to + expire, as long as tor fetches new ones soon after. Fixes bug + 31657; bugfix on 0.3.3.1-alpha. + + o Minor bugfixes (logging, backport from 0.4.1.1-alpha): + - Do not log a warning when running with an OpenSSL version other + than the one Tor was compiled with, if the two versions should be + compatible. Previously, we would warn whenever the version was + different. Fixes bug 30190; bugfix on 0.2.4.2-alpha. + + o Minor bugfixes (logging, backport from 0.4.2.1-alpha): + - Change log level of message "Hash of session info was not as + expected" to LOG_PROTOCOL_WARN. Fixes bug 12399; bugfix + on 0.1.1.10-alpha. + + o Minor bugfixes (logging, backport from 0.4.2.2-alpha): + - Rate-limit our the logging message about the obsolete .exit + notation. Previously, there was no limit on this warning, which + could potentially be triggered many times by a hostile website. + Fixes bug 31466; bugfix on 0.2.2.1-alpha. + + o Minor bugfixes (logging, protocol violations, backport from 0.4.2.2-alpha): + - Do not log a nonfatal assertion failure when receiving a VERSIONS + cell on a connection using the obsolete v1 link protocol. Log a + protocol_warn instead. Fixes bug 31107; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (mainloop, periodic events, in-process API, backport from 0.4.2.3-alpha): + - Reset the periodic events' "enabled" flag when Tor is shut down + cleanly. Previously, this flag was left on, which caused periodic + events not to be re-enabled when Tor was relaunched in-process + with tor_api.h after a shutdown. Fixes bug 32058; bugfix + on 0.3.3.1-alpha. + + o Minor bugfixes (memory leak, backport from 0.4.1.1-alpha): + - Avoid a minor memory leak that could occur on relays when failing + to create a "keys" directory. Fixes bug 30148; bugfix + on 0.3.3.1-alpha. + + o Minor bugfixes (memory leak, backport from 0.4.1.4-rc): + - Fix a trivial memory leak when parsing an invalid value + from a download schedule in the configuration. Fixes bug + 30894; bugfix on 0.3.4.1-alpha. + + o Minor bugfixes (NetBSD, backport from 0.4.1.2-alpha): + - Fix usage of minherit() on NetBSD and other platforms that define + MAP_INHERIT_{ZERO,NONE} instead of INHERIT_{ZERO,NONE}. Fixes bug + 30614; bugfix on 0.4.0.2-alpha. Patch from Taylor Campbell. + + o Minor bugfixes (onion services, backport from 0.4.1.1-alpha): + - Avoid a GCC 9.1.1 warning (and possible crash depending on libc + implemenation) when failing to load an onion service client + authorization file. Fixes bug 30475; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (out-of-memory handler, backport from 0.4.1.2-alpha): + - When purging the DNS cache because of an out-of-memory condition, + try purging just the older entries at first. Previously, we would + always purge the whole thing. Fixes bug 29617; bugfix + on 0.3.5.1-alpha. + + o Minor bugfixes (portability, backport from 0.4.1.2-alpha): + - Avoid crashing in our tor_vasprintf() implementation on systems + that define neither vasprintf() nor _vscprintf(). (This bug has + been here long enough that we question whether people are running + Tor on such systems, but we're applying the fix out of caution.) + Fixes bug 30561; bugfix on 0.2.8.2-alpha. Found and fixed by + Tobias Stoeckmann. + + o Minor bugfixes (process management, backport from 0.4.2.3-alpha): + - Remove overly strict assertions that triggered when a pluggable + transport failed to launch. Fixes bug 31091; bugfix + on 0.4.0.1-alpha. + - Remove an assertion in the Unix process backend. This assertion + would trigger when we failed to find the executable for a child + process. Fixes bug 31810; bugfix on 0.4.0.1-alpha. + + o Minor bugfixes (relay, backport from 0.4.2.2-alpha): + - Avoid crashing when starting with a corrupt keys directory where + the old ntor key and the new ntor key are identical. Fixes bug + 30916; bugfix on 0.2.4.8-alpha. + + o Minor bugfixes (rust, backport from 0.4.2.1-alpha): + - Correctly exclude a redundant rust build job in Travis. Fixes bug + 31463; bugfix on 0.3.5.4-alpha. + + o Minor bugfixes (testing, backport from 0.4.2.3-alpha): + - When testing port rebinding, don't busy-wait for tor to log. + Instead, actually sleep for a short time before polling again. + Also improve the formatting of control commands and log messages. + Fixes bug 31837; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (tls, logging, backport from 0.4.2.3-alpha): + - Log bugs about the TLS read buffer's length only once, rather than + filling the logs with similar warnings. Fixes bug 31939; bugfix + on 0.3.0.4-rc. + + o Minor bugfixes (v2 single onion services, backport from 0.4.2.1-alpha): + - Always retry v2 single onion service intro and rend circuits with + a 3-hop path. Previously, v2 single onion services used a 3-hop + path when rendezvous circuits were retried after a remote or + delayed failure, but a 1-hop path for immediate retries. Fixes bug + 23818; bugfix on 0.2.9.3-alpha. + - Make v3 single onion services fall back to a 3-hop intro, when all + intro points are unreachable via a 1-hop path. Previously, v3 + single onion services failed when all intro nodes were unreachable + via a 1-hop path. Fixes bug 23507; bugfix on 0.3.2.1-alpha. + + o Documentation (backport from 0.4.2.1-alpha): + - Use RFC 2397 data URL scheme to embed an image into tor-exit- + notice.html so that operators no longer have to host it + themselves. Closes ticket 31089. + + o Testing (backport from 0.4.1.2-alpha): + - Specify torrc paths (with empty files) when launching tor in + integration tests; refrain from reading user and system torrcs. + Resolves issue 29702. + + o Testing (continuous integration, backport from 0.4.1.1-alpha): + - In Travis, show stem's tor log after failure. Closes ticket 30234. + + o Testing (continuous integration, backport from 0.4.1.5): + - In Travis, make stem log a controller trace to the console, and + tail stem's tor log after failure. Closes ticket 30591. + - In Travis, only run the stem tests that use a tor binary. Closes + ticket 30694. + + o Testing (continuous integration, backport from 0.4.2.3-alpha): + - Disable all but one Travis CI macOS build, to mitigate slow + scheduling of Travis macOS jobs. Closes ticket 32177. + - Run the chutney IPv6 networks as part of Travis CI. Closes + ticket 30860. + - Simplify the Travis CI build matrix, and optimise for build time. + Closes ticket 31859. + - Use Windows Server 2019 instead of Windows Server 2016 in our + Appveyor builds. Closes ticket 32086. + + o Testing (continuous integration, backport from 0.4.2.4-rc): + - Use Ubuntu Bionic images for our Travis CI builds, so we can get a + recent version of coccinelle. But leave chutney on Ubuntu Trusty, + until we can fix some Bionic permissions issues (see ticket + 32240). Related to ticket 31919. + - Install the mingw OpenSSL package in Appveyor. This makes sure + that the OpenSSL headers and libraries match in Tor's Appveyor + builds. (This bug was triggered by an Appveyor image update.) + Fixes bug 32449; bugfix on 0.3.5.6-rc. + - In Travis, use Xcode 11.2 on macOS 10.14. Closes ticket 32241. + + o Testing (continuous integration, backport from 0.4.2.5): + - Require C99 standards-conforming code in Travis CI, but allow GNU gcc + extensions. Also activates clang's -Wtypedef-redefinition warnings. + Build some jobs with -std=gnu99, and some jobs without. + Closes ticket 32500. + +Changes in version 0.3.5.9 - 2019-12-09 + Tor 0.3.5.9 backports serveral fixes from later releases, including + several that affect bridge users, relay stability, onion services, + and much more. + + o Directory authority changes (backport from 0.4.1.5): + - The directory authority "dizum" has a new IP address. Closes + ticket 31406. + + o Major bugfixes (bridges, backport from 0.4.1.2-alpha): + - Consider our directory information to have changed when our list + of bridges changes. Previously, Tor would not re-compute the + status of its directory information when bridges changed, and + therefore would not realize that it was no longer able to build + circuits. Fixes part of bug 29875. + - Do not count previously configured working bridges towards our + total of working bridges. Previously, when Tor's list of bridges + changed, it would think that the old bridges were still usable, + and delay fetching router descriptors for the new ones. Fixes part + of bug 29875; bugfix on 0.3.0.1-alpha. + + o Major bugfixes (circuit build, guard, backport from 0.4.1.4-rc): + - When considering upgrading circuits from "waiting for guard" to + "open", always ignore circuits that are marked for close. Otherwise, + we can end up in the situation where a subsystem is notified that + a closing circuit has just opened, leading to undesirable + behavior. Fixes bug 30871; bugfix on 0.3.0.1-alpha. + + o Major bugfixes (NSS, relay, backport from 0.4.0.4-rc): + - When running with NSS, disable TLS 1.2 ciphersuites that use + SHA384 for their PRF. Due to an NSS bug, the TLS key exporters for + these ciphersuites don't work -- which caused relays to fail to + handshake with one another when these ciphersuites were enabled. + Fixes bug 29241; bugfix on 0.3.5.1-alpha. + + o Major bugfixes (Onion service reachability, backport from 0.4.1.3-alpha): + - Properly clean up the introduction point map when circuits change + purpose from onion service circuits to pathbias, measurement, or + other circuit types. This should fix some service-side instances + of introduction point failure. Fixes bug 29034; bugfix + on 0.3.2.1-alpha. + + o Major bugfixes (onion service v3, backport from 0.4.1.1-alpha): + - Fix an unreachable bug in which an introduction point could try to + send an INTRODUCE_ACK with a status code that Trunnel would refuse + to encode, leading the relay to assert(). We've consolidated the + ABI values into Trunnel now. Fixes bug 30454; bugfix + on 0.3.0.1-alpha. + - Clients can now handle unknown status codes from INTRODUCE_ACK + cells. (The NACK behavior will stay the same.) This will allow us + to extend status codes in the future without breaking the normal + client behavior. Fixes another part of bug 30454; bugfix + on 0.3.0.1-alpha. + + o Major bugfixes (torrc parsing, backport from 0.4.2.2-alpha): + - Stop ignoring torrc options after an %include directive, when the + included directory ends with a file that does not contain any + config options (but does contain comments or whitespace). Fixes + bug 31408; bugfix on 0.3.1.1-alpha. + + o Major bugfixes (v3 onion services, backport from 0.4.2.3-alpha): + - Onion services now always use the exact number of intro points + configured with the HiddenServiceNumIntroductionPoints option (or + fewer if nodes are excluded). Before, a service could sometimes + pick more intro points than configured. Fixes bug 31548; bugfix + on 0.3.2.1-alpha. + + o Minor features (address selection, backport from 0.4.0.3-alpha): + - Treat the subnet 100.64.0.0/10 as public for some purposes; + private for others. This subnet is the RFC 6598 (Carrier Grade + NAT) IP range, and is deployed by many ISPs as an alternative to + RFC 1918 that does not break existing internal networks. Tor now + blocks SOCKS and control ports on these addresses and warns users + if client ports or ExtORPorts are listening on a RFC 6598 address. + Closes ticket 28525. Patch by Neel Chauhan. + + o Minor features (bandwidth authority, backport from 0.4.0.4-rc): + - Make bandwidth authorities ignore relays that are reported in the + bandwidth file with the flag "vote=0". This change allows us to + report unmeasured relays for diagnostic reasons without including + their bandwidth in the bandwidth authorities' vote. Closes + ticket 29806. + + o Minor features (compile-time modules, backport from version 0.4.1.1-alpha): + - Add a "--list-modules" command to print a list of which compile- + time modules are enabled. Closes ticket 30452. + + o Minor features (continuous integration, backport from 0.4.0.4-rc): + - On Travis Rust builds, cleanup Rust registry and refrain from + caching the "target/" directory to speed up builds. Resolves + issue 29962. + + o Minor features (continuous integration, backport from 0.4.0.5): + - In Travis, tell timelimit to use stem's backtrace signals, and + launch python directly from timelimit, so python receives the + signals from timelimit, rather than make. Closes ticket 30117. + + o Minor features (continuous integration, backport from 0.4.1.1-alpha): + - Remove sudo configuration lines from .travis.yml as they are no + longer needed with current Travis build environment. Resolves + issue 30213. + + o Minor features (continuous integration, backport from 0.4.1.4-rc): + - Our Travis configuration now uses Chutney to run some network + integration tests automatically. Closes ticket 29280. + + o Minor features (continuous integration, backport from 0.4.2.2-alpha): + - When building on Appveyor and Travis, pass the "-k" flag to make, + so that we are informed of all compilation failures, not just the + first one or two. Closes ticket 31372. + + o Minor features (fallback directory list, backport from 0.4.1.4-rc): + - Replace the 157 fallbacks originally introduced in Tor 0.3.5.6-rc + in December 2018 (of which ~122 were still functional), with a + list of 148 fallbacks (70 new, 78 existing, 79 removed) generated + in June 2019. Closes ticket 28795. + + o Minor features (geoip, backport from 0.4.2.5): + - Update geoip and geoip6 to the December 3 2019 Maxmind GeoLite2 + Country database. Closes ticket 32685. + + o Minor features (NSS, diagnostic, backport from 0.4.0.4-rc): + - Try to log an error from NSS (if there is any) and a more useful + description of our situation if we are using NSS and a call to + SSL_ExportKeyingMaterial() fails. Diagnostic for ticket 29241. + + o Minor features (stem tests, backport from 0.4.2.1-alpha): + - Change "make test-stem" so it only runs the stem tests that use + tor. This change makes test-stem faster and more reliable. Closes + ticket 31554. + + o Minor bugfixes (security, backport from 0.4.0.4-rc): + - Verify in more places that we are not about to create a buffer + with more than INT_MAX bytes, to avoid possible OOB access in the + event of bugs. Fixes bug 30041; bugfix on 0.2.0.16. Found and + fixed by Tobias Stoeckmann. + - Fix a potential double free bug when reading huge bandwidth files. + The issue is not exploitable in the current Tor network because + the vulnerable code is only reached when directory authorities + read bandwidth files, but bandwidth files come from a trusted + source (usually the authorities themselves). Furthermore, the + issue is only exploitable in rare (non-POSIX) 32-bit architectures, + which are not used by any of the current authorities. Fixes bug + 30040; bugfix on 0.3.5.1-alpha. Bug found and fixed by + Tobias Stoeckmann. + + o Minor bugfix (continuous integration, backport from 0.4.0.4-rc): + - Reset coverage state on disk after Travis CI has finished. This + should prevent future coverage merge errors from causing the test + suite for the "process" subsystem to fail. The process subsystem + was introduced in 0.4.0.1-alpha. Fixes bug 29036; bugfix + on 0.2.9.15. + - Terminate test-stem if it takes more than 9.5 minutes to run. + (Travis terminates the job after 10 minutes of no output.) + Diagnostic for 29437. Fixes bug 30011; bugfix on 0.3.5.4-alpha. + + o Minor bugfixes (Appveyor CI, backport from 0.4.2.2-alpha): + - Avoid spurious errors when Appveyor CI fails before the install step. + Fixes bug 31884; bugfix on 0.3.4.2-alpha. + + o Minor bugfixes (build system, backport form 0.4.2.1-alpha): + - Do not include the deprecated on Linux or Windows + systems. Fixes bug 31673; bugfix on 0.2.5.4-alpha. + + o Minor bugfixes (C correctness, backport from 0.4.0.4-rc): + - Fix an unlikely memory leak in consensus_diff_apply(). Fixes bug + 29824; bugfix on 0.3.1.1-alpha. This is Coverity warning + CID 1444119. + + o Minor bugfixes (circuit isolation, backport from 0.4.1.3-alpha): + - Fix a logic error that prevented the SessionGroup sub-option from + being accepted. Fixes bug 22619; bugfix on 0.2.7.2-alpha. + + o Minor bugfixes (client, onion service v3, backport from 0.4.2.4-rc): + - Fix a BUG() assertion that occurs within a very small race window + between when a client intro circuit opens and when its descriptor + gets cleaned up from the cache. The circuit is now closed early, + which will trigger a re-fetch of the descriptor and continue the + connection. Fixes bug 28970; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (clock skew detection, backport from 0.4.1.5): + - Don't believe clock skew results from NETINFO cells that appear to + arrive before we sent the VERSIONS cells they are responding to. + Previously, we would accept them up to 3 minutes "in the past". + Fixes bug 31343; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (compilation warning, backport from 0.4.1.5): + - Fix a compilation warning on Windows about casting a function + pointer for GetTickCount64(). Fixes bug 31374; bugfix + on 0.2.9.1-alpha. + + o Minor bugfixes (compilation, backport from 0.4.0.2-alpha): + - Silence a compiler warning in test-memwipe.c on OpenBSD. Fixes bug + 29145; bugfix on 0.2.9.3-alpha. Patch from Kris Katterjohn. + + o Minor bugfixes (compilation, backport from 0.4.1.5): + - Avoid using labs() on time_t, which can cause compilation warnings + on 64-bit Windows builds. Fixes bug 31343; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (compilation, backport from 0.4.2.1-alpha): + - Suppress spurious float-conversion warnings from GCC when calling + floating-point classifier functions on FreeBSD. Fixes part of bug + 31687; bugfix on 0.3.1.5-alpha. + + o Minor bugfixes (compilation, unusual configurations, backport from 0.4.1.1-alpha): + - Avoid failures when building with the ALL_BUGS_ARE_FATAL option + due to missing declarations of abort(), and prevent other such + failures in the future. Fixes bug 30189; bugfix on 0.3.4.1-alpha. + + o Minor bugfixes (configuration, proxies, backport from 0.4.1.2-alpha): + - Fix a bug that prevented us from supporting SOCKS5 proxies that + want authentication along with configured (but unused!) + ClientTransportPlugins. Fixes bug 29670; bugfix on 0.2.6.1-alpha. + + o Minor bugfixes (connections, backport from 0.4.2.3-rc): + - Avoid trying to read data from closed connections, which can cause + needless loops in Libevent and infinite loops in Shadow. Fixes bug + 30344; bugfix on 0.1.1.1-alpha. + + o Minor bugfixes (continuous integration, backport from 0.4.1.3-alpha): + - Allow the test-stem job to fail in Travis, because it sometimes + hangs. Fixes bug 30744; bugfix on 0.3.5.4-alpha. + - Skip test_rebind on macOS in Travis, because it is unreliable on + macOS on Travis. Fixes bug 30713; bugfix on 0.3.5.1-alpha. + - Skip test_rebind when the TOR_SKIP_TEST_REBIND environment + variable is set. Fixes bug 30713; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (crash on exit, backport from 0.4.1.4-rc): + - Avoid a set of possible code paths that could try to use freed + memory in routerlist_free() while Tor was exiting. Fixes bug + 31003; bugfix on 0.1.2.2-alpha. + + o Minor bugfixes (directory authorities, backport from 0.4.1.3-alpha): + - Stop crashing after parsing an unknown descriptor purpose + annotation. We think this bug can only be triggered by modifying a + local file. Fixes bug 30781; bugfix on 0.2.0.8-alpha. + + o Minor bugfixes (directory authority, backport from 0.4.1.2-alpha): + - Move the "bandwidth-file-headers" line in directory authority + votes so that it conforms to dir-spec.txt. Fixes bug 30316; bugfix + on 0.3.5.1-alpha. + + o Minor bugfixes (error handling, backport from 0.4.2.1-alpha): + - On abort, try harder to flush the output buffers of log messages. + On some platforms (macOS), log messages could be discarded when + the process terminates. Fixes bug 31571; bugfix on 0.3.5.1-alpha. + - Report the tor version whenever an assertion fails. Previously, we + only reported the Tor version on some crashes, and some non-fatal + assertions. Fixes bug 31571; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (FreeBSD, PF-based proxy, IPv6, backport from 0.4.2.1-alpha): + - When extracting an IPv6 address from a PF-based proxy, verify that + we are actually configured to receive an IPv6 address, and log an + internal error if not. Fixes part of bug 31687; bugfix + on 0.2.3.4-alpha. + + o Minor bugfixes (guards, backport from 0.4.2.1-alpha): + - When tor is missing descriptors for some primary entry guards, + make the log message less alarming. It's normal for descriptors to + expire, as long as tor fetches new ones soon after. Fixes bug + 31657; bugfix on 0.3.3.1-alpha. + + o Minor bugfixes (logging, backport from 0.4.0.2-alpha): + - Avoid logging that we are relaxing a circuit timeout when that + timeout is fixed. Fixes bug 28698; bugfix on 0.2.4.7-alpha. + + o Minor bugfixes (logging, backport from 0.4.0.3-alpha): + - Correct a misleading error message when IPv4Only or IPv6Only is + used but the resolved address can not be interpreted as an address + of the specified IP version. Fixes bug 13221; bugfix on + 0.2.3.9-alpha. Patch from Kris Katterjohn. + - Log the correct port number for listening sockets when "auto" is + used to let Tor pick the port number. Previously, port 0 was + logged instead of the actual port number. Fixes bug 29144; bugfix + on 0.3.5.1-alpha. Patch from Kris Katterjohn. + - Stop logging a BUG() warning when Tor is waiting for exit + descriptors. Fixes bug 28656; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (logging, backport from 0.4.1.1-alpha): + - Do not log a warning when running with an OpenSSL version other + than the one Tor was compiled with, if the two versions should be + compatible. Previously, we would warn whenever the version was + different. Fixes bug 30190; bugfix on 0.2.4.2-alpha. + + o Minor bugfixes (logging, backport from 0.4.2.1-alpha): + - Change log level of message "Hash of session info was not as + expected" to LOG_PROTOCOL_WARN. Fixes bug 12399; bugfix + on 0.1.1.10-alpha. + + o Minor bugfixes (logging, backport from 0.4.2.2-alpha): + - Rate-limit our the logging message about the obsolete .exit + notation. Previously, there was no limit on this warning, which + could potentially be triggered many times by a hostile website. + Fixes bug 31466; bugfix on 0.2.2.1-alpha. + + o Minor bugfixes (logging, protocol violations, backport from 0.4.2.2-alpha): + - Do not log a nonfatal assertion failure when receiving a VERSIONS + cell on a connection using the obsolete v1 link protocol. Log a + protocol_warn instead. Fixes bug 31107; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (mainloop, periodic events, in-process API, backport from 0.4.2.3-alpha): + - Reset the periodic events' "enabled" flag when Tor is shut down + cleanly. Previously, this flag was left on, which caused periodic + events not to be re-enabled when Tor was relaunched in-process + with tor_api.h after a shutdown. Fixes bug 32058; bugfix + on 0.3.3.1-alpha. + + o Minor bugfixes (memory leak, backport from 0.4.1.1-alpha): + - Avoid a minor memory leak that could occur on relays when failing + to create a "keys" directory. Fixes bug 30148; bugfix + on 0.3.3.1-alpha. + + o Minor bugfixes (memory leak, backport from 0.4.1.4-rc): + - Fix a trivial memory leak when parsing an invalid value + from a download schedule in the configuration. Fixes bug + 30894; bugfix on 0.3.4.1-alpha. + + o Minor bugfixes (memory management, backport from 0.4.0.3-alpha): + - Refactor the shared random state's memory management so that it + actually takes ownership of the shared random value pointers. + Fixes bug 29706; bugfix on 0.2.9.1-alpha. + + o Minor bugfixes (memory management, testing, backport from 0.4.0.3-alpha): + - Stop leaking parts of the shared random state in the shared-random + unit tests. Fixes bug 29599; bugfix on 0.2.9.1-alpha. + + o Minor bugfixes (onion services, backport from 0.4.1.1-alpha): + - Avoid a GCC 9.1.1 warning (and possible crash depending on libc + implemenation) when failing to load an onion service client + authorization file. Fixes bug 30475; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (out-of-memory handler, backport from 0.4.1.2-alpha): + - When purging the DNS cache because of an out-of-memory condition, + try purging just the older entries at first. Previously, we would + always purge the whole thing. Fixes bug 29617; bugfix + on 0.3.5.1-alpha. + + o Minor bugfixes (portability, backport from 0.4.1.2-alpha): + - Avoid crashing in our tor_vasprintf() implementation on systems + that define neither vasprintf() nor _vscprintf(). (This bug has + been here long enough that we question whether people are running + Tor on such systems, but we're applying the fix out of caution.) + Fixes bug 30561; bugfix on 0.2.8.2-alpha. Found and fixed by + Tobias Stoeckmann. + + o Minor bugfixes (relay, backport from 0.4.2.2-alpha): + - Avoid crashing when starting with a corrupt keys directory where + the old ntor key and the new ntor key are identical. Fixes bug + 30916; bugfix on 0.2.4.8-alpha. + + o Minor bugfixes (rust, backport from 0.4.0.5): + - Abort on panic in all build profiles, instead of potentially + unwinding into C code. Fixes bug 27199; bugfix on 0.3.3.1-alpha. + + o Minor bugfixes (rust, backport from 0.4.2.1-alpha): + - Correctly exclude a redundant rust build job in Travis. Fixes bug + 31463; bugfix on 0.3.5.4-alpha. + + o Minor bugfixes (single onion services, backport from 0.4.0.3-alpha): + - Allow connections to single onion services to remain idle without + being disconnected. Previously, relays acting as rendezvous points + for single onion services were mistakenly closing idle rendezvous + circuits after 60 seconds, thinking that they were unused + directory-fetching circuits that had served their purpose. Fixes + bug 29665; bugfix on 0.2.1.26. + + o Minor bugfixes (stats, backport from 0.4.0.3-alpha): + - When ExtraInfoStatistics is 0, stop including PaddingStatistics in + relay and bridge extra-info documents. Fixes bug 29017; bugfix + on 0.3.1.1-alpha. + + o Minor bugfixes (testing, backport from 0.4.0.3-alpha): + - Downgrade some LOG_ERR messages in the address/* tests to + warnings. The LOG_ERR messages were occurring when we had no + configured network. We were failing the unit tests, because we + backported 28668 to 0.3.5.8, but did not backport 29530. Fixes bug + 29530; bugfix on 0.3.5.8. + - Fix our gcov wrapper script to look for object files at the + correct locations. Fixes bug 29435; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (testing, backport from 0.4.0.4-rc): + - Backport the 0.3.4 src/test/test-network.sh to 0.2.9. We need a + recent test-network.sh to use new chutney features in CI. Fixes + bug 29703; bugfix on 0.2.9.1-alpha. + - Fix a test failure on Windows caused by an unexpected "BUG" + warning in our tests for tor_gmtime_r(-1). Fixes bug 29922; bugfix + on 0.2.9.3-alpha. + + o Minor bugfixes (testing, backport from 0.4.2.3-alpha): + - When testing port rebinding, don't busy-wait for tor to log. + Instead, actually sleep for a short time before polling again. + Also improve the formatting of control commands and log messages. + Fixes bug 31837; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (TLS protocol, backport form 0.4.0.4-rc): + - When classifying a client's selection of TLS ciphers, if the + client ciphers are not yet available, do not cache the result. + Previously, we had cached the unavailability of the cipher list + and never looked again, which in turn led us to assume that the + client only supported the ancient V1 link protocol. This, in turn, + was causing Stem integration tests to stall in some cases. Fixes + bug 30021; bugfix on 0.2.4.8-alpha. + + o Minor bugfixes (tls, logging, backport from 0.4.2.3-alpha): + - Log bugs about the TLS read buffer's length only once, rather than + filling the logs with similar warnings. Fixes bug 31939; bugfix + on 0.3.0.4-rc. + + o Minor bugfixes (v2 single onion services, backport from 0.4.2.1-alpha): + - Always retry v2 single onion service intro and rend circuits with + a 3-hop path. Previously, v2 single onion services used a 3-hop + path when rendezvous circuits were retried after a remote or + delayed failure, but a 1-hop path for immediate retries. Fixes bug + 23818; bugfix on 0.2.9.3-alpha. + - Make v3 single onion services fall back to a 3-hop intro, when all + intro points are unreachable via a 1-hop path. Previously, v3 + single onion services failed when all intro nodes were unreachable + via a 1-hop path. Fixes bug 23507; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (Windows, CI, backport from 0.4.0.3-alpha): + - Skip the Appveyor 32-bit Windows Server 2016 job, and 64-bit + Windows Server 2012 R2 job. The remaining 2 jobs still provide + coverage of 64/32-bit, and Windows Server 2016/2012 R2. Also set + fast_finish, so failed jobs terminate the build immediately. Fixes + bug 29601; bugfix on 0.3.5.4-alpha. + + o Documentation (backport from 0.4.2.1-alpha): + - Use RFC 2397 data URL scheme to embed an image into tor-exit- + notice.html so that operators no longer have to host it + themselves. Closes ticket 31089. + + o Testing (backport from 0.4.1.2-alpha): + - Specify torrc paths (with empty files) when launching tor in + integration tests; refrain from reading user and system torrcs. + Resolves issue 29702. + + o Testing (continuous integration, backport from 0.4.1.1-alpha): + - In Travis, show stem's tor log after failure. Closes ticket 30234. + + o Testing (continuous integration, backport from 0.4.1.5): + - In Travis, make stem log a controller trace to the console, and + tail stem's tor log after failure. Closes ticket 30591. + - In Travis, only run the stem tests that use a tor binary. Closes + ticket 30694. + + o Testing (continuous integration, backport from 0.4.2.3-alpha): + - Disable all but one Travis CI macOS build, to mitigate slow + scheduling of Travis macOS jobs. Closes ticket 32177. + - Run the chutney IPv6 networks as part of Travis CI. Closes + ticket 30860. + - Simplify the Travis CI build matrix, and optimise for build time. + Closes ticket 31859. + - Use Windows Server 2019 instead of Windows Server 2016 in our + Appveyor builds. Closes ticket 32086. + + o Testing (continuous integration, backport from 0.4.2.4-rc): + - Use Ubuntu Bionic images for our Travis CI builds, so we can get a + recent version of coccinelle. But leave chutney on Ubuntu Trusty, + until we can fix some Bionic permissions issues (see ticket + 32240). Related to ticket 31919. + - Install the mingw OpenSSL package in Appveyor. This makes sure + that the OpenSSL headers and libraries match in Tor's Appveyor + builds.
