; bugfix on 0.2.1.1-alpha.
Minor bugfixes (bootstrap):
- Consistently use the consensus download schedule for authority certificates. Fixes bug 18816; bugfix on 0.2.4.13-alpha.
Minor bugfixes (build):
- Avoid spurious failures from configure files related to calling exit(0) in TOR_SEARCH_LIBRARY. Fixes bug 18625; bugfix on 0.2.0.1-alpha. Patch from “cypherpunks”.
- Do not link the unit tests against both the testing and non- testing versions of the static libraries. Fixes bug 18490; bugfix on 0.2.7.1-alpha.
- Resolve warnings when building on systems that are concerned with signed char. Fixes bug 18728; bugfix on 0.2.7.2-alpha and 0.2.6.1-alpha.
- Silence spurious clang-scan warnings in the ed25519_donna code by explicitly initializing some objects. Fixes bug 18384; bugfix on 0.2.7.2-alpha. Patch by teor.
- When libscrypt.h is found, but no libscrypt library can be linked, treat libscrypt as absent. Fixes bug 19161; bugfix on 0.2.6.1-alpha.
- Cause the unit tests to compile correctly on mingw64 versions that lack sscanf. Fixes bug 19213; bugfix on 0.2.7.1-alpha.
- Don’t try to use the pthread_condattr_setclock() function unless it actually exists. Fixes compilation on NetBSD-6.x. Fixes bug 17819; bugfix on 0.2.6.3-alpha.
- Fix backtrace compilation on FreeBSD. Fixes bug17827; bugfix on 0.2.5.2-alpha.
- Fix search for libevent libraries on OpenBSD (and other systems that install libevent 1 and libevent 2 in parallel). Fixes bug 16651; bugfix on 0.1.0.7-rc. Patch from “rubiate”.
- Isolate environment variables meant for tests from the rest of the build system. Fixes bug 17818; bugfix on 0.2.7.3-rc.
- Mark all object files that include micro-revision.i as depending on it, so as to make parallel builds more reliable. Fixes bug 17826; bugfix on 0.2.5.1-alpha.
- Remove config.log only from make distclean, not from make clean. Fixes bug 17924; bugfix on 0.2.4.1-alpha.
- Replace usage of ‘INLINE’ with ‘inline’. Fixes bug 17804; bugfix on 0.0.2pre8.
- Remove an #endif from configure.ac so that we correctly detect the presence of in6_addr.s6_addr32. Fixes bug 17923; bugfix on 0.2.0.13-alpha.
Minor bugfixes (client, bootstrap):
- Count receipt of new microdescriptors as progress towards bootstrapping. Previously, with EntryNodes set, Tor might not successfully repopulate the guard set on bootstrapping. Fixes bug 16825; bugfix on 0.2.3.1-alpha.
Minor bugfixes (code correctness):
- Fix a bad memory handling bug that would occur if we had queued a cell on a channel’s incoming queue. Fortunately, we can’t actually queue a cell like that as our code is constructed today, but it’s best to avoid this kind of error, even if there isn’t any code that triggers it today. Fixes bug18570; bugfix on 0.2.4.4-alpha.
- Assert that allocated memory held by the reputation code is freed according to its internal counters. Fixes bug 17753; bugfix on 0.1.1.1-alpha.
- Assert when the TLS contexts fail to initialize. Fixes bug 17683; bugfix on 0.0.6.
- Update to the latest version of Trunnel, which tries harder to avoid generating code that can invoke memcpy(p,NULL,0). Bug found by clang address sanitizer. Fixes bug18373; bugfix on 0.2.7.2-alpha.
- When closing an entry connection, generate a warning if we should have sent an end cell for it but we haven’t. Fixes bug 17876; bugfix on 0.2.3.2-alpha.
Minor bugfixes (configuration):
- Fix a tiny memory leak when parsing a port configuration ending in “:auto”. Fixes bug18374; bugfix on 0.2.3.3-alpha.
Minor bugfixes (containers):
- If we somehow attempt to construct a heap with more than 1073741822 elements, avoid an integer overflow when maintaining the heap property. Fixes bug 18296; bugfix on 0.1.2.1-alpha.
Minor bugfixes (controller, microdescriptors):
- Make GETINFO dir/status-vote/current/consensus conform to the control specification by returning “551 Could not open cached consensus…” when not caching consensuses. Fixes bug 18920; bugfix on 0.2.2.6-alpha.
Minor bugfixes (crypto):
- Check the return value of HMAC() and assert on failure. Fixes bug 17658; bugfix on 0.2.3.6-alpha. Patch by teor.
Minor bugfixes (directories):
- When fetching extrainfo documents, compare their SHA256 digests and Ed25519 signing key certificates with the routerinfo that led us to fetch them, rather than with the most recent routerinfo. Otherwise we generate many spurious warnings about mismatches. Fixes bug 17150; bugfix on 0.2.7.2-alpha.
- When generating a URL for a directory server on an IPv6 address, wrap the IPv6 address in square brackets. Fixes bug 18051; bugfix on 0.2.3.9-alpha. Patch from Malek.
Minor bugfixes (downloading):
