Loading ChangeLog +122 −0 Original line number Diff line number Diff line Changes in version 0.4.2.2-alpha - 2019-10-0? This release fixes several bugs from the previous alpha release. o Major bugfixes (embedded Tor): - 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 (torrc): - 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 Minor features (authority): - 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 Minor features (auto-formatting scripts): - When annotating C macros, never generate a line that our check-spaces script would reject. Closes ticket 31759. - When annotating C macros, try to remove cases of double-negation. Closes ticket 31779. o Minor features (continuous integration): - When building on Appveyor, pass the "-k" flag to make, so that we are informed of all compilation failures, not just the first one or two. Closes part of ticket 31372. - When building on Travis, pass the "-k" flag to make, so that we are informed of all compilation failures, not just the first one or two. Closes part of ticket 31372. o Minor features (geoip): - Update geoip and geoip6 to the October 1 2019 Maxmind GeoLite2 Country database. Closes ticket 31931. o Minor features (maintenance scripts): - Add a coccinelle script to detect bugs caused by incrementing or decrementing a variable inside a call to log_debug(). Since log_debug() is a macro whose arguments are conditionally evaluated, it is usually an error to do this. One such bug was 30628, in which SENDME cells were miscounted by a decrement operator inside a log_debug() call. Closes ticket 30743. o Minor features (onion services v3): - Assist users who try to setup v2 client authorization in v3 onion services by pointing them to the right documentation. Closes ticket 28966. o Minor bugfixes (Appveyor CI): - Avoid spurious errors when Appveyor CI fails before the install step. Fixes bug 31884; bugfix on 0.3.4.2-alpha. o Minor bugfixes (best practices tracker): - When listing overbroad exceptions, do not also list problems, and do not list insufficiently broad exceptions. Fixes bug 31338; bugfix on 0.4.2.1-alpha. o Minor bugfixes (controller protocol): - Fix the MAPADDRESS controller command to accept one or more arguments. Previously, it required two or more arguments, and ignored the first. Fixes bug 31772; bugfix on 0.4.1.1-alpha. o Minor bugfixes (logging): - 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. - When initialising log domain masks, only set known log domains. Fixes bug 31854; bugfix on 0.2.1.1-alpha. o Minor bugfixes (logging, protocol violations): - 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 (modules): - Explain what the optional Directory Authority module is, and what happens when it is disabled. Fixes bug 31825; bugfix on 0.3.4.1-alpha. o Minor bugfixes (multithreading): - Avoid some undefined behaviour when freeing mutexes. Fixes bug 31736; bugfix on 0.0.7. o Minor bugfixes (relay): - 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 (tests, SunOS): - 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 Code simplification and refactoring (onion services): - Interface for function `decrypt_desc_layer` cleaned up. Closes ticket 31589. o Code simplification and refactoring: - Refactor connection_control_process_inbuf() to reduce the size of a practracker exception. Closes ticket 31840. - Refactor the microdescs_parse_from_string() function into smaller pieces, for better comprehensibility. Closes ticket 31675. - Use SEVERITY_MASK_IDX() to find the LOG_* mask indexes in the unit tests and fuzzers, rather than using hard-coded values. Closes ticket 31334. o Documentation: - Document the signal-safe logging behaviour in the tor man page. Also add some comments to the relevant functions. Closes ticket 31839. - Explain why we can't destroy the backtrace buffer mutex. Explain why we don't need to destroy the log mutex. Closes ticket 31736. - The Tor source code repository now includes a (somewhat dated) description of Tor's modular architecture, in doc/HACKING/design. This is based on the old "tor-guts.git" repository, which we are adopting and superseding. Closes ticket 31849. Changes in version 0.4.1.6 - 2019-09-19 This release backports several bugfixes to improve stability and correctness.
