[RELEASE] Release candidate 0.4.8.3-rc
by David Goulet 04 Aug '23

04 Aug '23

Greetings, We just relased 0.4.8.3-rc: https://forum.torproject.org/t/release-candidate-0-4-8-3-rc/8629 Here is the ChangeLog. Cheers! Changes in version 0.4.8.3-rc - 2023-08-04 This is the first release candidate (and likely the only) of the 0.4.8.x series. We fixed a major conflux bugfix which was a fatal asserts on the relay Exit side. See below for more details. Couple minor bugfixes. Until stable, name of the game here is stabilization. o Major bugfixes (conflux): - Fix a relay-side assert crash caused by attempts to use a conflux circuit between circuit close and free, such that no legs were on the conflux set. Fixed by nulling out the stream's circuit back- pointer when the last leg is removed. Additional checks and log messages have been added to detect other cases. Fixes bug 40827; bugfix on 0.4.8.1-alpha. o Minor features (fallbackdir): - Regenerate fallback directories generated on August 04, 2023. - Regenerate fallback directories generated on July 26, 2023. o Minor features (geoip data): - Update the geoip files to match the IPFire Location Database, as retrieved on 2023/07/26. - Update the geoip files to match the IPFire Location Database, as retrieved on 2023/08/04. o Minor bugfixes (compilation): - Fix all -Werror=enum-int-mismatch warnings. No behavior change. Fixes bug 40824; bugfix on 0.3.5.1-alpha. o Minor bugfixes (protocol warn): - Wrap a handful of cases where ProtocolWarning logs could emit IP addresses. Fixes bug 40828; bugfix on 0.3.5.1-alpha. -- nQQ5ObgzQzcePV1s1cEOo40knHabaCl2Fv6fw+TKiks=

[RELEASE] Tor 0.4.7.14 stable
by David Goulet 26 Jul '23

26 Jul '23

Greetings, We have just released 0.4.7.14 stable: https://forum.torproject.org/t/stable-release-0-4-7-14/8493 Below is the ChangeLog. Cheers! David -- Changes in version 0.4.7.14 - 2023-07-26 This version contains several minor fixes and one major bugfix affecting vanguards (onion service). As usual, we recommend upgrading to this version as soon as possible. o Major bugfixes (vanguards): - Rotate to a new L2 vanguard whenever an existing one loses the Stable or Fast flag. Previously, we would leave these relays in the L2 vanguard list but never use them, and if all of our vanguards end up like this we wouldn't have any middle nodes left to choose from so we would fail to make onion-related circuits. Fixes bug 40805; bugfix on 0.4.7.1-alpha. o Minor feature (CI): - Update CI to use Debian Bullseye for runners. o Minor feature (lzma): - Fix compiler warnings for liblzma >= 5.3.1. Closes ticket 40741. o Minor features (directory authorities): - Directory authorities now include their AuthDirMaxServersPerAddr config option in the consensus parameter section of their vote. Now external tools can better predict how they will behave. Implements ticket 40753. o Minor features (fallbackdir): - Regenerate fallback directories generated on July 26, 2023. o Minor features (geoip data): - Update the geoip files to match the IPFire Location Database, as retrieved on 2023/07/26. o Minor bugfix (relay, logging): - The wrong max queue cell size was used in a protocol warning logging statement. Fixes bug 40745; bugfix on 0.4.7.1-alpha. o Minor bugfixes (compilation): - Fix all -Werror=enum-int-mismatch warnings. No behavior change. Fixes bug 40824; bugfix on 0.3.5.1-alpha. o Minor bugfixes (metrics): - Decrement hs_intro_established_count on introduction circuit close. Fixes bug 40751; bugfix on 0.4.7.12. o Minor bugfixes (sandbox): - Allow membarrier for the sandbox. And allow rt_sigprocmask when compiled with LTTng. Fixes bug 40799; bugfix on 0.3.5.1-alpha. -- cjlyhJWoh9tk5jdAyBvT6egdmgfeNQjX16LRl2NPolY=

[RELEASE] Tor 0.4.8.2-alpha
by David Goulet 12 Jul '23

12 Jul '23

Greetings, We just released the second alpha of the 0.4.8.x series. Here is the announcement and below the ChangeLog. https://forum.torproject.org/t/alpha-release-0-4-8-2-alpha/8353 Cheers! David Changes in version 0.4.8.2-alpha - 2023-07-12 This is our second alpha containing some minor bugfixes and one major bugfix about L2 vanguard rotation. We believe this will be the last alpha before the rc in a couple of weeks. o Major bugfixes (vanguards): - Rotate to a new L2 vanguard whenever an existing one loses the Stable or Fast flag. Previously, we would leave these relays in the L2 vanguard list but never use them, and if all of our vanguards end up like this we wouldn't have any middle nodes left to choose from so we would fail to make onion-related circuits. Fixes bug 40805; bugfix on 0.4.7.1-alpha. o Minor feature (hs): - Fix compiler warnings in equix and hashx when building with clang. Closes ticket 40800. o Minor features (fallbackdir): - Regenerate fallback directories generated on July 12, 2023. o Minor features (geoip data): - Update the geoip files to match the IPFire Location Database, as retrieved on 2023/07/12. o Minor bugfix (congestion control): - Reduce the accepted range of a circuit's negotiated 'cc_sendme_inc' to be +/- 1 from the consensus parameter value. Fixes bug 40569; bugfix on 0.4.7.4-alpha. - Remove unused congestion control algorithms and BDP calculation code, now that we have settled on and fully tuned Vegas. Fixes bug 40566; bugfix on 0.4.7.4-alpha. - Update default congestion control parameters to match consensus. Fixes bug 40709; bugfix on 0.4.7.4-alpha. o Minor bugfixes (compilation): - Fix "initializer is not a constant" compilation error that manifests itself on gcc versions < 8.1 and MSVC. Fixes bug 40773; bugfix on 0.4.8.1-alpha o Minor bugfixes (conflux): - Count leg launch attempts prior to attempting to launch them. This avoids inifinite launch attempts due to internal circuit building failures. Additionally, double-check that we have enough exits in our consensus overall, before attempting to launch conflux sets. Fixes bug 40811; bugfix on 0.4.8.1-alpha. - Fix a case where we were resuming reading on edge connections that were already marked for close. Fixes bug 40801; bugfix on 0.4.8.1-alpha. - Fix stream attachment order when creating conflux circuits, so that stream attachment happens after finishing the full link handshake, rather than upon set finalization. Fixes bug 40801; bugfix on 0.4.8.1-alpha. - Handle legs being closed or destroyed before computing an RTT (resulting in warns about too many legs). Fixes bug 40810; bugfix on 0.4.8.1-alpha. - Remove a "BUG" warning from conflux_pick_first_leg that can be triggered by broken or malicious clients. Fixes bug 40801; bugfix on 0.4.8.1-alpha. o Minor bugfixes (KIST): - Prevent KISTSchedRunInterval from having values of 0 or 1, neither of which work properly. Additionally, make a separate KISTSchedRunIntervalClient parameter, so that the client and relay KIST values can be set separately. Set the default of both to 2ms. Fixes bug 40808; bugfix on 0.3.2.1-alpha. -- SCCJSq3++gLvtcViLCnYL3xswoYt5w4BmK/HeCEDeks=
