If we find no + new bugs or regression here, then the first stable 0.3.2. release will be + nearly identical to this. + + o Major bugfixes (circuit prediction): + - Fix circuit prediction logic so that a client doesn't treat a stream as + being "handled" by a circuit if that circuit already has isolation + settings on it that might make it incompatible with the stream. This + change should make Tor clients more responsive by improving their + chances of having a pre-created circuit ready for use when a new client + request arrives. Fixes bug 18859; bugfix on 0.2.3.3-alpha. + + o Minor features (logging): + - Provide better warnings when the getrandom() syscall fails. + Closes ticket 24500. + + o Minor features (portability): + - Tor now compiles correctly on arm64 with libseccomp-dev installed. + (It doesn't yet work with the sandbox enabled.) Closes ticket 24424. + + o Minor bugfix (KIST scheduler): + - Downgrade a warning to log info when the monotonic time diff is + negative. This can happen on platform not supporting monotonic time. The + scheduler recovers from this without any problem. Fixes bug 23696; + bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (bridge clients, bootstrap): + - Retry directory downloads when we get our first bridge descriptor + during bootstrap or while reconnecting to the network. Keep retrying + every time we get a bridge descriptor, until we have a reachable bridge. + Fixes bug 24367; bugfix on 0.2.0.3-alpha. + - Stop delaying bridge descriptor fetches when we have cached bridge + descriptors. Instead, only delay bridge descriptor fetches when we + have at least one reachable bridge. + Fixes bug 24367; bugfix on 0.2.0.3-alpha. + - Stop delaying directory fetches when we have cached bridge descriptors. + Instead, only delay bridge descriptor fetches when all our bridges are + definitely unreachable. + Fixes bug 24367; bugfix on 0.2.0.3-alpha. + + o Minor bugfixes (compilation): + - Fix a signed/unsigned comparison warning introduced by our + fix to TROVE-2017-009. Fixes bug 24480; bugfix on 0.2.5.16. + + o Minor bugfixes (correctness): + - Fix several places in our codebase where a C compiler would be likely + to eliminate a check, based on assuming that undefined behavior had not + happened elsewhere in the code. These cases are usually a sign of + redundant checking, or dubious arithmetic. Found by Georg Koppen using + the "STACK" tool from Wang, Zeldovich, Kaashoek, and + Solar-Lezama. Fixes bug 24423; bugfix on various Tor versions. + + o Minor bugfixes (hidden service v3): + - Fix a race between the circuit close and free where the service would + launch a new intro circuit after the close, and then fail to register it + before the free of the previously closed circuit. This was making the + service unable to find the established intro circuit and thus not upload + its descriptor. It can make a service unavailable for up to 24 hours. + Fixes bug 23603; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (scheduler): + - Properly set the scheduler state of an unopened channel in the KIST + scheduler main loop. This prevents a harmless but annoying log warning. + Fixes bug 24502; bugfix on 0.3.2.4-alpha. + + o Minor bugfixes (scheduler, KIST): + - Avoid a possible integer overflow when computing the available space on + the TCP buffer of a channel. This has no security implications but can + make KIST not behave properly by allowing more cells on a already + saturated connection.
