Fixes bugs 21394 and 18580; bugfix on + 0.1.2.2-alpha, which introduced eventdns. Thanks to Dhalgren for + identifying and finding a workaround to this bug and to Moritz, + Arthur Edelstein, and Roger for helping to track it down and + analyze it. + + o Major bugfixes (scheduler, channel): + - Stop processing scheduled channels if they closed while flushing + cells. This can happen if the write on the connection fails + leading to the channel being closed while in the scheduler loop. + Fixes bug 23751; bugfix on 0.3.2.1-alpha. + + o Minor features (logging, scheduler): + - Introduce a SCHED_BUG() function to log extra information about + the scheduler state if we ever catch a bug in the scheduler. + Closes ticket 23753. + + o Minor features (removed deprecations): + - The ClientDNSRejectInternalAddresses flag can once again be set in + non-testing Tor networks, so long as they do not use the default + directory authorities. This change also removes the deprecation of + this flag from 0.2.9.2-alpha. Closes ticket 21031. + + o Minor features (testing): + - Our fuzzing tests now test the encrypted portions of v3 onion + service descriptors. Implements more of 21509. + + o Minor bugfixes (directory client): + - On failure to download directory information, delay retry attempts + by a random amount based on the "decorrelated jitter" algorithm. + Our previous delay algorithm tended to produce extra-long delays + too easily. Fixes bug 23816; bugfix on 0.2.9.1-alpha. + + o Minor bugfixes (IPv6, v3 single onion services): + - Remove buggy code for IPv6-only v3 single onion services, and + reject attempts to configure them. This release supports IPv4, + dual-stack, and IPv6-only v3 onion services; and IPv4 and dual- + stack v3 single onion services. Fixes bug 23820; bugfix + on 0.3.2.1-alpha. + + o Minor bugfixes (logging, relay): + - Give only a protocol warning when the ed25519 key is not + consistent between the descriptor and microdescriptor of a relay. + This can happen, for instance, if the relay has been flagged + NoEdConsensus. Fixes bug 24025; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (manpage, onion service): + - Document that the HiddenServiceNumIntroductionPoints option is + 0-10 for v2 services and 0-20 for v3 services. Fixes bug 24115; + bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (memory leaks): + - Fix a minor memory leak at exit in the KIST scheduler. This bug + should have no user-visible impact. Fixes bug 23774; bugfix + on 0.3.2.1-alpha. + - Fix a memory leak when decrypting a badly formatted v3 onion + service descriptor. Fixes bug 24150; bugfix on 0.3.2.1-alpha. + Found by OSS-Fuzz; this is OSS-Fuzz issue 3994. + + o Minor bugfixes (onion services): + - Cache some needed onion service client information instead of + constantly computing it over and over again. Fixes bug 23623; + bugfix on 0.3.2.1-alpha. + - Properly retry HSv3 descriptor fetches when missing required + directory information. Fixes bug 23762; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (path selection): + - When selecting relays by bandwidth, avoid a rounding error that + could sometimes cause load to be imbalanced incorrectly. + Previously, we would always round upwards; now, we round towards + the nearest integer. This had the biggest effect when a relay's + weight adjustments should have given it weight 0, but it got + weight 1 instead. Fixes bug 23318; bugfix on 0.2.4.3-alpha. + - When calculating the fraction of nodes that have descriptors, and + all nodes in the network have zero bandwidths, count the number of + nodes instead. Fixes bug 23318; bugfix on 0.2.4.10-alpha. + - Actually log the total bandwidth in compute_weighted_bandwidths(). + Fixes bug 24170; bugfix on 0.2.4.3-alpha. + + o Minor bugfixes (relay, crash): + - Avoid a crash when transitioning from client mode to bridge mode. + Previously, we would launch the worker threads whenever our + "public server" mode changed, but not when our "server" mode + changed. Fixes bug 23693; bugfix on 0.2.6.3-alpha. + + o Minor bugfixes (testing): + - Fix a spurious fuzzing-only use of an uninitialized value. Found + by Brian Carpenter. Fixes bug 24082; bugfix on 0.3.0.3-alpha. + - Test that IPv6-only clients can use microdescriptors when running + "make test-network-all". Requires chutney master 61c28b9 or later. + Closes ticket 24109. + + Changes in version 0.3.2.3-alpha - 2017-10-27 Tor 0.3.2.3-alpha is the third release in the 0.3.2 series. It fixes numerous small bugs in earlier versions of 0.3.2.x, and adds a new
