Bug found by fuzzing with + Radamsa. Fixes bug 6811; bugfix on 0.2.0.20-rc. + + o Major bugfixes: + - Fix a possible crash bug when checking for deactivated circuits + in connection_or_flush_from_first_active_circuit(). Fixes bug 6341; + bugfix on 0.2.2.7-alpha. Bug report and fix received pseudonymously. + - Allow routers to detect that their own DirPorts are running. When + we removed support for versions_supports_begindir, we also + accidentally removed the mechanism we used to self-test our + DirPort. Diagnosed with help from kargig. Fixes bugs 6814 and 6815; + bugfix on 0.2.4.2-alpha. + + o Security features: + - Switch to a completely time-invariant approach for picking nodes + weighted by bandwidth. Our old approach would run through the + part of the loop after it had made its choice slightly slower + than it ran through the part of the loop before it had made its + choice. Addresses ticket 6538. + + o Minor bugfixes: + - Correct file sizes when reading binary files on Cygwin, to avoid + a bug where Tor would fail to read its state file. Fixes bug 6844; + bugfix on 0.1.2.7-alpha. + - Fix round_to_power_of_2() so it doesn't invoke undefined behavior + with large values. This situation was untriggered, but nevertheless + incorrect. Fixes bug 6831; bugfix on 0.2.0.1-alpha. + - Reject consensus votes with more than 64 known-flags. We aren't even + close to that limit yet, and our code doesn't handle it correctly. + Fixes bug 6833; bugfix on 0.2.0.1-alpha. + - Avoid undefined behaviour when parsing the list of supported + rendezvous/introduction protocols in a hidden service descriptor. + Previously, Tor would have confused (as-yet-unused) protocol version + numbers greater than 32 with lower ones on many platforms. Fixes + bug 6827; bugfix on 0.2.0.10-alpha. Found by George Kadianakis. + - Fix building with older versions of GCC that don't like preprocessor + directives inside macro arguments. Found by grarpamp. Fixes bug + 6842; bugfix on 0.2.4.2-alpha. + - Switch weighted node selection rule from using a list of doubles + to using a list of int64_t. This change should make the process + slightly easier to debug and maintain. Needed to finish ticket 6538. + + o Code simplification and refactoring: + - Move the generic "config" code into a new file, and have "config.c" + hold only torrc- and state-related code. Resolves ticket 6823. + - Move the core of our "choose a weighted element at random" logic + into its own function, and give it unit tests. Now the logic is + testable, and a little less fragile too. + + o Documentation fixes: + - Resolve a typo in torrc.sample.in. Fixes bug 6819; bugfix on + 0.2.3.14-alpha. + + Changes in version 0.2.3.22-rc - 2012-09-11 Tor 0.2.3.22-rc fixes another opportunity for a remotely triggerable assertion. |
