+ +Changes in version 0.2.8.3-alpha - 2016-05-26 + Tor 0.2.8.3-alpha resolves several bugs, most of them introduced over + the course of the 0.2.8 development cycle. It improves the behavior of + directory clients, fixes several crash bugs, fixes a gap in compiler + hardening, and allows the full integration test suite to run on + more platforms. + + o Major bugfixes (security, client, DNS proxy): + - Stop a crash that could occur when a client running with DNSPort + received a query with multiple address types, and the first + address type was not supported. Found and fixed by Scott Dial. + Fixes bug 18710; bugfix on 0.2.5.4-alpha. + + o Major bugfixes (security, compilation): + - Correctly detect compiler flags on systems where _FORTIFY_SOURCE + is predefined. Previously, our use of -D_FORTIFY_SOURCE would + cause a compiler warning, thereby making other checks fail, and + needlessly disabling compiler-hardening support. Fixes one case of + bug 18841; bugfix on 0.2.3.17-beta. Patch from "trudokal". + + o Major bugfixes (security, directory authorities): + - Fix a crash and out-of-bounds write during authority voting, when + the list of relays includes duplicate ed25519 identity keys. Fixes + bug 19032; bugfix on 0.2.8.2-alpha. + + o Major bugfixes (client, bootstrapping): + - Check if bootstrap consensus downloads are still needed when the + linked connection attaches. This prevents tor making unnecessary + begindir-style connections, which are the only directory + connections tor clients make since the fix for 18483 was merged. + - Fix some edge cases where consensus download connections may not + have been closed, even though they were not needed. Related to fix + for 18809. + - Make relays retry consensus downloads the correct number of times, + rather than the more aggressive client retry count. Fixes part of + ticket 18809. + - Stop downloading consensuses when we have a consensus, even if we + don't have all the certificates for it yet. Fixes bug 18809; + bugfix on 0.2.8.1-alpha. Patches by arma and teor. + + o Major bugfixes (directory mirrors): + - Decide whether to advertise begindir support in the the same way + we decide whether to advertise our DirPort. Allowing these + decisions to become out-of-sync led to surprising behavior like + advertising begindir support when hibernation made us not + advertise a DirPort. Resolves bug 18616; bugfix on 0.2.8.1-alpha. + Patch by teor. + + o Major bugfixes (IPv6 bridges, client): + - Actually use IPv6 addresses when selecting directory addresses for + IPv6 bridges. Fixes bug 18921; bugfix on 0.2.8.1-alpha. Patch + by "teor". + + o Major bugfixes (key management): + - If OpenSSL fails to generate an RSA key, do not retain a dangling + pointer to the previous (uninitialized) key value. The impact here + should be limited to a difficult-to-trigger crash, if OpenSSL is + running an engine that makes key generation failures possible, or + if OpenSSL runs out of memory. Fixes bug 19152; bugfix on + 0.2.1.10-alpha. Found by Yuan Jochen Kang, Suman Jana, and + Baishakhi Ray. + + o Major bugfixes (testing): + - Fix a bug that would block 'make test-network-all' on systems where + IPv6 packets were lost. Fixes bug 19008; bugfix on tor-0.2.7.3-rc. + - Avoid "WSANOTINITIALISED" warnings in the unit tests. Fixes bug 18668; + bugfix on 0.2.8.1-alpha. + + o Minor features (clients): + - Make clients, onion services, and bridge relays always use an + encrypted begindir connection for directory requests. Resolves + ticket 18483. Patch by "teor". + + o Minor features (fallback directory mirrors): + - Give each fallback the same weight for client selection; restrict + fallbacks to one per operator; report fallback directory detail + changes when rebuilding list; add new fallback directory mirrors + to the whitelist; update fallback directories based on the latest + OnionOO data; and any other minor simplifications and fixes. + Closes tasks 17158, 17905, 18749, bug 18689, and fixes part of bug + 18812 on 0.2.8.1-alpha; patch by "teor". + + o Minor features (geoip): + - Update geoip and geoip6 to the May 4 2016 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (assert, portability): + - Fix an assertion failure in memarea.c on systems where "long" is + shorter than the size of a pointer. Fixes bug 18716; bugfix + on 0.2.1.1-alpha. + + o Minor bugfixes (bootstrap): + - Consistently use the consensus download schedule for authority + certificates. Fixes bug 18816; bugfix on 0.2.4.13-alpha. + + o Minor bugfixes (build): + - Remove a pair of redundant AM_CONDITIONAL declarations from + configure.ac. Fixes one final case of bug 17744; bugfix + on 0.2.8.2-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. + - 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. + + o Minor bugfixes (client): + - Turn all TestingClientBootstrap* into non-testing torrc options. + This changes simply renames them by removing "Testing" in front of + them and they do not require TestingTorNetwork to be enabled + anymore. Fixes bug 18481; bugfix on 0.2.8.1-alpha. + - Make directory node selection more reliable, mainly for IPv6-only + clients and clients with few reachable addresses. Fixes bug 18929; + bugfix on 0.2.8.1-alpha. Patch by "teor". + + o 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. + + o Minor bugfixes (crypto, portability): + - The SHA3 and SHAKE routines now produce the correct output on Big + Endian systems. No code calls either algorithm yet, so this is + primarily a build fix. Fixes bug 18943; bugfix on 0.2.8.1-alpha. + - Tor now builds again with the recent OpenSSL 1.1 development + branch (tested against 1.1.0-pre4 and 1.1.0-pre5-dev). Closes + ticket 18286. + + o 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. + + o Minor bugfixes (logging): + - When we can't generate a signing key because OfflineMasterKey is + set, do not imply that we should have been able to load it. Fixes + bug 18133; bugfix on 0.2.7.2-alpha. + - Stop periodic_event_dispatch() from blasting twelve lines per + second at loglevel debug. Fixes bug 18729; fix on 0.2.8.1-alpha. + - When rejecting a misformed INTRODUCE2 cell, only log at + PROTOCOL_WARN severity. Fixes bug 18761; bugfix on 0.2.8.2-alpha. + + o Minor bugfixes (pluggable transports): + - Avoid reporting a spurious error when we decide that we don't need + to terminate a pluggable transport because it has already exited. + Fixes bug 18686; bugfix on 0.2.5.5-alpha. + + o Minor bugfixes (pointer arithmetic): + - Fix a bug in memarea_alloc() that could have resulted in remote + heap write access, if Tor had ever passed an unchecked size to + memarea_alloc(). Fortunately, all the sizes we pass to + memarea_alloc() are pre-checked to be less than 128 kilobytes. + Fixes bug 19150; bugfix on 0.2.1.1-alpha. Bug found by + Guido Vranken. + + o Minor bugfixes (relays): + - Consider more config options when relays decide whether to + regenerate their descriptor. Fixes more of bug 12538; bugfix + on 0.2.8.1-alpha. + - Resolve some edge cases where we might launch an ORPort + reachability check even when DisableNetwork is set. Noticed while + fixing bug 18616; bugfix on 0.2.3.9-alpha. + + o Minor bugfixes (statistics): + - We now include consensus downloads via IPv6 in our directory- + request statistics. Fixes bug 18460; bugfix on 0.2.3.14-alpha. + + o Minor bugfixes (testing): + - Allow directories in small networks to bootstrap by skipping + DirPort checks when the consensus has no exits. Fixes bug 19003; + bugfix on 0.2.8.1-alpha. Patch by teor. + - Fix a small memory leak that would occur when the + TestingEnableCellStatsEvent option was turned on. Fixes bug 18673; + bugfix on 0.2.5.2-alpha. + + o Minor bugfixes (time handling): + - When correcting a corrupt 'struct tm' value, fill in the tm_wday + field. Otherwise, our unit tests crash on Windows. Fixes bug + 18977; bugfix on 0.2.2.25-alpha. + + o Documentation: + - Document the contents of the 'datadir/keys' subdirectory in the + manual page. Closes ticket 17621. + - Stop recommending use of nicknames to identify relays in our + MapAddress documentation. Closes ticket 18312. + + Changes in version 0.2.8.2-alpha - 2016-03-28 Tor 0.2.8.2-alpha is the second alpha in its series. It fixes numerous bugs in earlier versions of Tor, including some that prevented
