+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.
