Fixes bug 40504; bugfix on 0.4.6.1-alpha. Changes in version 0.4.6.9 - 2021-12-15 This version fixes several bugs from earlier versions of Tor. One important piece is the removal of DNS timeout metric from the overload general signal. See below for more details. o Major bugfixes (relay, overload): - Don't make Tor DNS timeout trigger an overload general state. These timeouts are different from DNS server timeout. They have to be seen as timeout related to UX and not because of a network problem. Fixes bug 40527; bugfix on 0.4.6.1-alpha. o Minor feature (reproducible build): - The repository can now build reproducible tarballs which adds the build command "make dist-reprod" for that purpose. Closes ticket 26299. o Minor features (compilation): - Give an error message if trying to build with a version of LibreSSL known not to work with Tor. (There's an incompatibility with LibreSSL versions 3.2.1 through 3.4.0 inclusive because of their incompatibility with OpenSSL 1.1.1's TLSv1.3 APIs.) Closes ticket 40511. o Minor features (fallbackdir): - Regenerate fallback directories generated on December 15, 2021. o Minor features (geoip data): - Update the geoip files to match the IPFire Location Database, as retrieved on 2021/12/15. o Minor bugfixes (compilation): - Fix our configuration logic to detect whether we had OpenSSL 3: previously, our logic was reversed. This has no other effect than to change whether we suppress deprecated API warnings. Fixes bug 40429; bugfix on 0.3.5.13. o Minor bugfixes (relay): - Reject IPv6-only DirPorts. Our reachability self-test forces DirPorts to be IPv4, but our configuration parser allowed them to be IPv6-only, which led to an assertion failure. Fixes bug 40494; bugfix on 0.4.5.1-alpha. o Documentation (man, relay): - Missing "OverloadStatistics" in tor.1 manpage. Fixes bug 40504; bugfix on 0.4.6.1-alpha.

Changes in version 0.4.7.3-alpha - 2021-12-15 This third alpha release of the 0.4.7.x series fixes several bugs including two major ones affecting Bridges and Relays (see below). If you are running an earlier 0.4.7.x version, you should upgrade to this version. o Major bugfixes (bridges): - Make Tor work reliably again when you have multiple bridges configured and one or more of them are unreachable. The problem came because we require that we have bridge descriptors for both of our first two bridges (else we refuse to try to connect), but in some cases we would wait three hours before trying to fetch these missing descriptors, and/or never recover when we do try to fetch them.

Closes ticket 40355. o Minor bugfix (pluggable transport): - Do not kill a managed proxy if one of its transport configurations emits a method error. Instead log a warning and continue processing method arguments. Fixes bug 7362; bugfix on 0.2.3.6-alpha. o Minor bugfixes (bridges): - When we don't yet have a descriptor for one of our bridges, disable the entry guard retry schedule on that bridge. The entry guard retry schedule and the bridge descriptor retry schedule can conflict, e.g. where we mark a bridge as "maybe up" yet we don't try to fetch its descriptor yet, leading Tor to wait (refusing to do anything) until it becomes time to fetch the descriptor. Fixes bug 40497; bugfix on 0.3.0.3-alpha. o Minor bugfixes (compilation): - Fix our configuration logic to detect whether we had OpenSSL 3: previously, our logic was reversed. This has no other effect than to change whether we suppress deprecated API warnings. Fixes bug 40429; bugfix on 0.3.5.13. o Minor bugfixes (controller, path bias): - When a circuit's path is specified, in full or in part, from the controller API, do not count that circuit towards our path-bias calculations. (Doing so was incorrect, since we cannot tell whether the controller is selecting relays randomly.) Resolves a "Bug" warning. Fixes bug 40515; bugfix on 0.2.4.10-alpha. o Minor bugfixes (logging): - When we no longer have enough directory information to use the network, we would log a notice-level message -- but we would not reliably log a message when we recovered and resumed using the network. Now make sure there is always a corresponding message about recovering. Fixes bug 40496; bugfix on 0.3.5.1-alpha. o Minor bugfixes (performance, DoS): - Fix one case of a not-especially viable denial-of-service attack found by OSS-Fuzz in our consensus-diff parsing code. This attack causes a lot small of memory allocations and then immediately frees them: this is only slow when running with all the sanitizers enabled. Fixes one case of bug 40472; bugfix on 0.3.1.1-alpha. o Minor bugfixes (relay): - Reject IPv6-only DirPorts. Our reachability self-test forces DirPorts to be IPv4, but our configuration parser allowed them to be IPv6-only, which led to an assertion failure. Fixes bug 40494; bugfix on 0.4.5.1-alpha. o Minor bugfixes (sandbox): - Fix the sandbox on i386 by modifying it to allow the "clock_gettime64" and "statx" system calls and to filter the "chown32" and "stat64" system calls in place of "chown" and "stat", respectively.
