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 port + as being "handled" by a circuit if that circuit already has + isolation settings on it. This change should make Tor clients more + responsive by improving their chances of having a pre-created + circuit ready for use when a 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 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 part of 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 part of 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 part of 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 (onion service v3): + - Fix a race where an onion service would launch a new intro circuit + after closing an old one, but fail to register it before freeing + the previously closed circuit. This bug was making the service + unable to find the established intro circuit and thus not upload + its descriptor, thus making a service unavailable for up to 24 + hours. Fixes bug 23603; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (scheduler, KIST): + - 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. + - Avoid a possible integer overflow when computing the available + space on the TCP buffer of a channel. This had no security + implications; but could make KIST allow too many cells on a + saturated connection. Fixes bug 24590; bugfix on 0.3.2.1-alpha. + - Downgrade to "info" a harmless warning about the monotonic time + moving backwards: This can happen on platform not supporting + monotonic time. Fixes bug 23696; bugfix on 0.3.2.1-alpha. + + Changes in version 0.3.2.6-alpha - 2017-12-01 This version of Tor is the latest in the 0.3.2 alpha series. It includes fixes for several important security issues. All Tor users
