All Tor users should upgrade to this release, or + to another of the releases coming out today. + + Note: the Tor 0.3.0 series will no longer be supported after 26 Jan + 2018. If you need a release with long-term support, please stick with + the 0.2.9 series. Otherwise, please upgrade to 0.3.1 or later. + + o Major bugfixes (security, backport from 0.3.2.6-alpha): + - Fix a denial of service bug where an attacker could use a + malformed directory object to cause a Tor instance to pause while + OpenSSL would try to read a passphrase from the terminal. (Tor + instances run without a terminal, which is the case for most Tor + packages, are not impacted.) Fixes bug 24246; bugfix on every + version of Tor. Also tracked as TROVE-2017-011 and CVE-2017-8821. + Found by OSS-Fuzz as testcase 6360145429790720. + - Fix a denial of service issue where an attacker could crash a + directory authority using a malformed router descriptor. Fixes bug + 24245; bugfix on 0.2.9.4-alpha. Also tracked as TROVE-2017-010 + and CVE-2017-8820. + - When checking for replays in the INTRODUCE1 cell data for a + (legacy) onion service, correctly detect replays in the RSA- + encrypted part of the cell. We were previously checking for + replays on the entire cell, but those can be circumvented due to + the malleability of Tor's legacy hybrid encryption. This fix helps + prevent a traffic confirmation attack. Fixes bug 24244; bugfix on + 0.2.4.1-alpha. This issue is also tracked as TROVE-2017-009 + and CVE-2017-8819. + + o Major bugfixes (security, onion service v2, backport from 0.3.2.6-alpha): + - Fix a use-after-free error that could crash v2 Tor onion services + when they failed to open circuits while expiring introduction + points. Fixes bug 24313; bugfix on 0.2.7.2-alpha. This issue is + also tracked as TROVE-2017-013 and CVE-2017-8823. + + o Major bugfixes (security, relay, backport from 0.3.2.6-alpha): + - When running as a relay, make sure that we never build a path + through ourselves, even in the case where we have somehow lost the + version of our descriptor appearing in the consensus. Fixes part + of bug 21534; bugfix on 0.2.0.1-alpha. This issue is also tracked + as TROVE-2017-012 and CVE-2017-8822. + - When running as a relay, make sure that we never choose ourselves + as a guard. Fixes part of bug 21534; bugfix on 0.3.0.1-alpha. This + issue is also tracked as TROVE-2017-012 and CVE-2017-8822. + + o Major bugfixes (exit relays, DNS, backport from 0.3.2.4-alpha): + - Fix an issue causing DNS to fail on high-bandwidth exit nodes, + making them nearly unusable. 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 Minor features (security, windows, backport from 0.3.1.1-alpha): + - Enable a couple of pieces of Windows hardening: one + (HeapEnableTerminationOnCorruption) that has been on-by-default + since Windows 8, and unavailable before Windows 7; and one + (PROCESS_DEP_DISABLE_ATL_THUNK_EMULATION) which we believe doesn't + affect us, but shouldn't do any harm. Closes ticket 21953. + + o Minor features (bridge, backport from 0.3.1.9): + - Bridges now include notice in their descriptors that they are + bridges, and notice of their distribution status, based on their + publication settings. Implements ticket 18329. For more fine- + grained control of how a bridge is distributed, upgrade to 0.3.2.x + or later. + + o Minor features (directory authority, backport from 0.3.2.6-alpha): + - Add an IPv6 address for the "bastet" directory authority. Closes + ticket 24394. + + o Minor features (geoip): + - Update geoip and geoip6 to the November 6 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfix (relay address resolution, backport from 0.3.2.1-alpha): + - Avoid unnecessary calls to directory_fetches_from_authorities() on + relays, to prevent spurious address resolutions and descriptor + rebuilds. This is a mitigation for bug 21789. Fixes bug 23470; + bugfix on in 0.2.8.1-alpha. + + o Minor bugfixes (compilation, backport from 0.3.2.1-alpha): + - Fix unused variable warnings in donna's Curve25519 SSE2 code. + Fixes bug 22895; bugfix on 0.2.7.2-alpha. + + o Minor bugfixes (logging, relay shutdown, annoyance, backport from 0.3.2.2-alpha): + - When a circuit is marked for close, do not attempt to package any + cells for channels on that circuit. Previously, we would detect + this condition lower in the call stack, when we noticed that the + circuit had no attached channel, and log an annoying message. + Fixes bug 8185; bugfix on 0.2.5.4-alpha. + + o Minor bugfixes (relay, crash, backport from 0.3.2.4-alpha): + - 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, backport from 0.3.1.6-rc): + - Fix an undersized buffer in test-memwipe.c. Fixes bug 23291; + bugfix on 0.2.7.2-alpha. Found and patched by Ties Stuij. + + +Changes in version 0.3.0.12 - 2017-10-25 + Tor 0.3.0.12 backports a collection of bugfixes from later Tor release + series, including a bugfix for a crash issue that had affected relays + under memory pressure. It also adds a new directory authority, Bastet. + + Note: the Tor 0.3.0 series will no longer be supported after 26 Jan + 2018. If you need a release with long-term support, please stick with + the 0.2.9 series. Otherwise, please upgrade to 0.3.1 or later. + + o Directory authority changes: + - Add "Bastet" as a ninth directory authority to the default list. + Closes ticket 23910. + - The directory authority "Longclaw" has changed its IP address. + Closes ticket 23592. + + o Major bugfixes (relay, crash, assertion failure, backport from 0.3.2.2-alpha): + - Fix a timing-based assertion failure that could occur when the + circuit out-of-memory handler freed a connection's output buffer. + Fixes bug 23690; bugfix on 0.2.6.1-alpha. + + o Minor features (directory authorities, backport from 0.3.2.2-alpha): + - Remove longclaw's IPv6 address, as it will soon change. Authority + IPv6 addresses were originally added in 0.2.8.1-alpha. This leaves + 3/8 directory authorities with IPv6 addresses, but there are also + 52 fallback directory mirrors with IPv6 addresses. Resolves 19760. + + o Minor features (geoip): + - Update geoip and geoip6 to the October 4 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (directory authority, backport from 0.3.1.5-alpha): + - When a directory authority rejects a descriptor or extrainfo with + a given digest, mark that digest as undownloadable, so that we do + not attempt to download it again over and over. We previously + tried to avoid downloading such descriptors by other means, but we + didn't notice if we accidentally downloaded one anyway. This + behavior became problematic in 0.2.7.2-alpha, when authorities + began pinning Ed25519 keys. Fixes bug 22349; bugfix + on 0.2.1.19-alpha. + + o Minor bugfixes (hidden service, relay, backport from 0.3.2.2-alpha): + - Avoid a possible double close of a circuit by the intro point on + error of sending the INTRO_ESTABLISHED cell. Fixes bug 23610; + bugfix on 0.3.0.1-alpha. + + o Minor bugfixes (memory safety, backport from 0.3.2.3-alpha): + - Clear the address when node_get_prim_orport() returns early. + Fixes bug 23874; bugfix on 0.2.8.2-alpha. + + o Minor bugfixes (Windows service, backport from 0.3.1.6-rc): + - When running as a Windows service, set the ID of the main thread + correctly. Failure to do so made us fail to send log messages to + the controller in 0.2.1.16-rc, slowed down controller event + delivery in 0.2.7.3-rc and later, and crash with an assertion + failure in 0.3.1.1-alpha. Fixes bug 23081; bugfix on 0.2.1.6-alpha. + Patch and diagnosis from "Vort". + + +Changes in version 0.3.0.11 - 2017-09-18 + Tor 0.3.0.11 backports a collection of bugfixes from Tor the 0.3.1 + series. + + Most significantly, it includes a fix for TROVE-2017-008, a + security bug that affects hidden services running with the + SafeLogging option disabled. For more information, see + https://trac.torproject.org/projects/tor/ticket/23490 + + o Minor features (code style, backport from 0.3.1.7): + - Add "Falls through" comments to our codebase, in order to silence + GCC 7's -Wimplicit-fallthrough warnings. Patch from Andreas + Stieger. Closes ticket 22446. + + o Minor features: + - Update geoip and geoip6 to the September 6 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (compilation, backport from 0.3.1.7): + - Avoid compiler warnings in the unit tests for calling tor_sscanf() + with wide string outputs. Fixes bug 15582; bugfix on 0.2.6.2-alpha. + + o Minor bugfixes (controller, backport from 0.3.1.7): + - Do not crash when receiving a HSPOST command with an empty body. + Fixes part of bug 22644; bugfix on 0.2.7.1-alpha. + - Do not crash when receiving a POSTDESCRIPTOR command with an empty + body. Fixes part of bug 22644; bugfix on 0.2.0.1-alpha. + + o Minor bugfixes (file limits, osx, backport from 0.3.1.5-alpha): + - When setting the maximum number of connections allowed by the OS, + always allow some extra file descriptors for other files. Fixes + bug 22797; bugfix on 0.2.0.10-alpha. + + o Minor bugfixes (logging, relay, backport from 0.3.1.6-rc): + - Remove a forgotten debugging message when an introduction point + successfully establishes a hidden service prop224 circuit with + a client. + - Change three other log_warn() for an introduction point to + protocol warnings, because they can be failure from the network + and are not relevant to the operator. Fixes bug 23078; bugfix on + 0.3.0.1-alpha and 0.3.0.2-alpha. + + +Changes in version 0.3.0.10 - 2017-08-02 + Tor 0.3.0.10 backports a collection of small-to-medium bugfixes + from the current Tor alpha series. OpenBSD users and TPROXY users + should upgrade; others are probably okay sticking with 0.3.0.9. + + o Major features (build system, continuous integration, backport from 0.3.1.5-alpha): + - Tor's repository now includes a Travis Continuous Integration (CI) + configuration file (.travis.yml). This is meant to help new + developers and contributors who fork Tor to a Github repository be + better able to test their changes, and understand what we expect + to pass. To use this new build feature, you must fork Tor to your + Github account, then go into the "Integrations" menu in the + repository settings for your fork and enable Travis, then push + your changes. Closes ticket 22636. + + o Major bugfixes (linux TPROXY support, backport from 0.3.1.1-alpha): + - Fix a typo that had prevented TPROXY-based transparent proxying + from working under Linux. Fixes bug 18100; bugfix on 0.2.6.3-alpha. + Patch from "d4fq0fQAgoJ". + + o Major bugfixes (openbsd, denial-of-service, backport from 0.3.1.5-alpha): + - Avoid an assertion failure bug affecting our implementation of + inet_pton(AF_INET6) on certain OpenBSD systems whose strtol() + handling of "0xfoo" differs from what we had expected. Fixes bug + 22789; bugfix on 0.2.3.8-alpha. Also tracked as TROVE-2017-007. + + o Minor features (backport from 0.3.1.5-alpha): + - Update geoip and geoip6 to the July 4 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (bandwidth accounting, backport from 0.3.1.2-alpha): + - Roll over monthly accounting at the configured hour and minute, + rather than always at 00:00. Fixes bug 22245; bugfix on 0.0.9rc1. + Found by Andrey Karpov with PVS-Studio. + + o Minor bugfixes (compilation warnings, backport from 0.3.1.5-alpha): + - Suppress -Wdouble-promotion warnings with clang 4.0. Fixes bug 22915; + bugfix on 0.2.8.1-alpha. + - Fix warnings when building with libscrypt and openssl scrypt + support on Clang. Fixes bug 22916; bugfix on 0.2.7.2-alpha. + - When building with certain versions of the mingw C header files, + avoid float-conversion warnings when calling the C functions + isfinite(), isnan(), and signbit(). Fixes bug 22801; bugfix + on 0.2.8.1-alpha. + + o Minor bugfixes (compilation, mingw, backport from 0.3.1.1-alpha): + - Backport a fix for an "unused variable" warning that appeared + in some versions of mingw. Fixes bug 22838; bugfix on + 0.2.8.1-alpha. + + o Minor bugfixes (coverity build support, backport from 0.3.1.5-alpha): + - Avoid Coverity build warnings related to our BUG() macro. By + default, Coverity treats BUG() as the Linux kernel does: an + instant abort(). We need to override that so our BUG() macro + doesn't prevent Coverity from analyzing functions that use it. + Fixes bug 23030; bugfix on 0.2.9.1-alpha. + + o Minor bugfixes (directory authority, backport from 0.3.1.1-alpha): + - When rejecting a router descriptor for running an obsolete version + of Tor without ntor support, warn about the obsolete tor version, + not the missing ntor key. Fixes bug 20270; bugfix on 0.2.9.3-alpha. + + o Minor bugfixes (linux seccomp2 sandbox, backport from 0.3.1.5-alpha): + - Avoid a sandbox failure when trying to re-bind to a socket and + mark it as IPv6-only. Fixes bug 20247; bugfix on 0.2.5.1-alpha. + + o Minor bugfixes (unit tests, backport from 0.3.1.5-alpha) + - Fix a memory leak in the link-handshake/certs_ok_ed25519 test. + Fixes bug 22803; bugfix on 0.3.0.1-alpha. + + +Changes in version 0.3.0.9 - 2017-06-29 + Tor 0.3.0.9 fixes a path selection bug that would allow a client + to use a guard that was in the same network family as a chosen exit + relay. This is a security regression; all clients running earlier + versions of 0.3.0.x or 0.3.1.x should upgrade to 0.3.0.9 or + 0.3.1.4-alpha. + + This release also backports several other bugfixes from the 0.3.1.x + series. + + o Major bugfixes (path selection, security, backport from 0.3.1.4-alpha): + - When choosing which guard to use for a circuit, avoid the exit's + family along with the exit itself. Previously, the new guard + selection logic avoided the exit, but did not consider its family. + Fixes bug 22753; bugfix on 0.3.0.1-alpha. Tracked as TROVE-2017- + 006 and CVE-2017-0377. + + o Major bugfixes (entry guards, backport from 0.3.1.1-alpha): + - Don't block bootstrapping when a primary bridge is offline and we + can't get its descriptor. Fixes bug 22325; fixes one case of bug + 21969; bugfix on 0.3.0.3-alpha. + + o Major bugfixes (entry guards, backport from 0.3.1.4-alpha): + - When starting with an old consensus, do not add new entry guards + unless the consensus is "reasonably live" (under 1 day old). Fixes + one root cause of bug 22400; bugfix on 0.3.0.1-alpha. + + o Minor features (geoip): + - Update geoip and geoip6 to the June 8 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (voting consistency, backport from 0.3.1.1-alpha): + - Reject version numbers with non-numeric prefixes (such as +, -, or + whitespace). Disallowing whitespace prevents differential version + parsing between POSIX-based and Windows platforms. Fixes bug 21507 + and part of 21508; bugfix on 0.0.8pre1. + + o Minor bugfixes (linux seccomp2 sandbox, backport from 0.3.1.4-alpha): + - Permit the fchmod system call, to avoid crashing on startup when + starting with the seccomp2 sandbox and an unexpected set of + permissions on the data directory or its contents. Fixes bug + 22516; bugfix on 0.2.5.4-alpha. + + o Minor bugfixes (defensive programming, backport from 0.3.1.4-alpha): + - Fix a memset() off the end of an array when packing cells. This + bug should be harmless in practice, since the corrupted bytes are + still in the same structure, and are always padding bytes, + ignored, or immediately overwritten, depending on compiler + behavior. Nevertheless, because the memset()'s purpose is to make + sure that any other cell-handling bugs can't expose bytes to the + network, we need to fix it. Fixes bug 22737; bugfix on + 0.2.4.11-alpha. Fixes CID 1401591. + + +Changes in version 0.3.0.8 - 2017-06-08 + Tor 0.3.0.8 fixes a pair of bugs that would allow an attacker to + remotely crash a hidden service with an assertion failure. Anyone + running a hidden service should upgrade to this version, or to some + other version with fixes for TROVE-2017-004 and TROVE-2017-005. + + Tor 0.3.0.8 also includes fixes for several key management bugs + that sometimes made relays unreliable, as well as several other + bugfixes described below. + + o Major bugfixes (hidden service, relay, security, backport + from 0.3.1.3-alpha): + - Fix a remotely triggerable assertion failure when a hidden service + handles a malformed BEGIN cell. Fixes bug 22493, tracked as + TROVE-2017-004 and as CVE-2017-0375; bugfix on 0.3.0.1-alpha. + - Fix a remotely triggerable assertion failure caused by receiving a + BEGIN_DIR cell on a hidden service rendezvous circuit. Fixes bug + 22494, tracked as TROVE-2017-005 and CVE-2017-0376; bugfix + on 0.2.2.1-alpha. + + o Major bugfixes (relay, link handshake, backport from 0.3.1.3-alpha): + - When performing the v3 link handshake on a TLS connection, report + that we have the x509 certificate that we actually used on that + connection, even if we have changed certificates since that + connection was first opened. Previously, we would claim to have + used our most recent x509 link certificate, which would sometimes + make the link handshake fail. Fixes one case of bug 22460; bugfix + on 0.2.3.6-alpha. + + o Major bugfixes (relays, key management, backport from 0.3.1.3-alpha): + - Regenerate link and authentication certificates whenever the key + that signs them changes; also, regenerate link certificates + whenever the signed key changes. Previously, these processes were + only weakly coupled, and we relays could (for minutes to hours) + wind up with an inconsistent set of keys and certificates, which + other relays would not accept. Fixes two cases of bug 22460; + bugfix on 0.3.0.1-alpha. + - When sending an Ed25519 signing->link certificate in a CERTS cell, + send the certificate that matches the x509 certificate that we + used on the TLS connection. Previously, there was a race condition + if the TLS context rotated after we began the TLS handshake but + before we sent the CERTS cell. Fixes a case of bug 22460; bugfix + on 0.3.0.1-alpha. + + o Major bugfixes (hidden service v3, backport from 0.3.1.1-alpha): + - Stop rejecting v3 hidden service descriptors because their size + did not match an old padding rule. Fixes bug 22447; bugfix on + tor-0.3.0.1-alpha. + + o Minor features (fallback directory list, backport from 0.3.1.3-alpha): + - Replace the 177 fallbacks originally introduced in Tor 0.2.9.8 in + December 2016 (of which ~126 were still functional) with a list of + 151 fallbacks (32 new, 119 unchanged, 58 removed) generated in May + 2017. Resolves ticket 21564. + + o Minor bugfixes (configuration, backport from 0.3.1.1-alpha): + - Do not crash when starting with LearnCircuitBuildTimeout 0. Fixes + bug 22252; bugfix on 0.2.9.3-alpha. + + o Minor bugfixes (correctness, backport from 0.3.1.3-alpha): + - Avoid undefined behavior when parsing IPv6 entries from the geoip6 + file. Fixes bug 22490; bugfix on 0.2.4.6-alpha. + + o Minor bugfixes (link handshake, backport from 0.3.1.3-alpha): + - Lower the lifetime of the RSA->Ed25519 cross-certificate to six + months, and regenerate it when it is within one month of expiring. + Previously, we had generated this certificate at startup with a + ten-year lifetime, but that could lead to weird behavior when Tor + was started with a grossly inaccurate clock. Mitigates bug 22466; + mitigation on 0.3.0.1-alpha. + + o Minor bugfixes (memory leak, directory authority, backport from + 0.3.1.2-alpha): + - When directory authorities reject a router descriptor due to + keypinning, free the router descriptor rather than leaking the + memory. Fixes bug 22370; bugfix on 0.2.7.2-alpha. + + + +Changes in version 0.3.0.7 - 2017-05-15 + Tor 0.3.0.7 fixes a medium-severity security bug in earlier versions + of Tor 0.3.0.x, where an attacker could cause a Tor relay process to + exit. Relays running earlier versions of Tor 0.3.0.x should upgrade; + clients are not affected. + + o Major bugfixes (hidden service directory, security): + - Fix an assertion failure in the hidden service directory code, + which could be used by an attacker to remotely cause a Tor relay + process to exit. Relays running earlier versions of Tor 0.3.0.x + should upgrade. This security issue is tracked as TROVE-2017-002. + Fixes bug 22246; bugfix on 0.3.0.1-alpha. + + o Minor features: + - Update geoip and geoip6 to the May 2 2017 Maxmind GeoLite2 + Country database. + + o Minor features (future-proofing): + - Tor no longer refuses to download microdescriptors or descriptors + if they are listed as "published in the future". This change will + eventually allow us to stop listing meaningful "published" dates + in microdescriptor consensuses, and thereby allow us to reduce the + resources required to download consensus diffs by over 50%. + Implements part of ticket 21642; implements part of proposal 275. + + o Minor bugfixes (Linux seccomp2 sandbox): + - The getpid() system call is now permitted under the Linux seccomp2 + sandbox, to avoid crashing with versions of OpenSSL (and other + libraries) that attempt to learn the process's PID by using the + syscall rather than the VDSO code. Fixes bug 21943; bugfix + on 0.2.5.1-alpha. + + +Changes in version 0.3.0.6 - 2017-04-26 + Tor 0.3.0.6 is the first stable release of the Tor 0.3.0 series. + + With the 0.3.0 series, clients and relays now use Ed25519 keys to + authenticate their link connections to relays, rather than the old + RSA1024 keys that they used before. (Circuit crypto has been + Curve25519-authenticated since 0.2.4.8-alpha.) We have also replaced + the guard selection and replacement algorithm to behave more robustly + in the presence of unreliable networks, and to resist guard- + capture attacks. + + This series also includes numerous other small features and bugfixes, + along with more groundwork for the upcoming hidden-services revamp. + + Per our stable release policy, we plan to support the Tor 0.3.0 + release series for at least the next nine months, or for three months + after the first stable release of the 0.3.1 series: whichever is + longer. If you need a release with long-term support, we recommend + that you stay with the 0.2.9 series. + + Below are the changes since 0.3.0.5-rc. For a list of all changes + since 0.2.9, see the ReleaseNotes file. + + o Minor features (geoip): + - Update geoip and geoip6 to the April 4 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (control port): + - The GETINFO extra-info/digest/<digest> command was broken because + of a wrong base16 decode return value check, introduced when + refactoring that API. Fixes bug 22034; bugfix on 0.2.9.1-alpha. + + o Minor bugfixes (crash prevention): + - Fix a (currently untriggerable, but potentially dangerous) crash + bug when base32-encoding inputs whose sizes are not a multiple of + 5. Fixes bug 21894; bugfix on 0.2.9.1-alpha. + + +Changes in version 0.3.0.5-rc - 2017-04-05 + Tor 0.3.0.5-rc fixes a few remaining bugs, large and small, in the + 0.3.0 release series. + + This is the second release candidate in the Tor 0.3.0 series, and has + much fewer changes than the first. If we find no new bugs or + regressions here, the first stable 0.3.0 release will be nearly + identical to it. + + o Major bugfixes (crash, directory connections): + - Fix a rare crash when sending a begin cell on a circuit whose + linked directory connection had already been closed. Fixes bug + 21576; bugfix on 0.2.9.3-alpha. Reported by Alec Muffett. + + o Major bugfixes (guard selection): + - Fix a guard selection bug where Tor would refuse to bootstrap in + some cases if the user swapped a bridge for another bridge in + their configuration file. Fixes bug 21771; bugfix on 0.3.0.1-alpha. + Reported by "torvlnt33r". + + o Minor features (geoip): + - Update geoip and geoip6 to the March 7 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfix (compilation): + - Fix a warning when compiling hs_service.c. Previously, it had no + exported symbols when compiled for libor.a, resulting in a + compilation warning from clang. Fixes bug 21825; bugfix + on 0.3.0.1-alpha. + + o Minor bugfixes (hidden services): + - Make hidden services check for failed intro point connections, + even when they have exceeded their intro point creation limit. + Fixes bug 21596; bugfix on 0.2.7.2-alpha. Reported by Alec Muffett. + - Make hidden services with 8 to 10 introduction points check for + failed circuits immediately after startup. Previously, they would + wait for 5 minutes before performing their first checks. Fixes bug + 21594; bugfix on 0.2.3.9-alpha. Reported by Alec Muffett. + + o Minor bugfixes (memory leaks): + - Fix a memory leak when using GETCONF on a port option. Fixes bug + 21682; bugfix on 0.3.0.3-alpha. + + o Minor bugfixes (relay): + - Avoid a double-marked-circuit warning that could happen when we + receive DESTROY cells under heavy load. Fixes bug 20059; bugfix + on 0.1.0.1-rc. + + o Minor bugfixes (tests): + - Run the entry_guard_parse_from_state_full() test with the time set + to a specific date. (The guard state that this test was parsing + contained guards that had expired since the test was first + written.) Fixes bug 21799; bugfix on 0.3.0.1-alpha. + + o Documentation: + - Update the description of the directory server options in the + manual page, to clarify that a relay no longer needs to set + DirPort in order to be a directory cache. Closes ticket 21720. + + +Changes in version 0.3.0.4-rc - 2017-03-01 + Tor 0.3.0.4-rc fixes some remaining bugs, large and small, in the + 0.3.0 release series, and introduces a few reliability features to + keep them from coming back. + + This is the first release candidate in the Tor 0.3.0 series. If we + find no new bugs or regressions here, the first stable 0.3.0 release + will be nearly identical to it. + + o Major bugfixes (bridges): + - When the same bridge is configured multiple times with the same + identity, but at different address:port combinations, treat those + bridge instances as separate guards. This fix restores the ability + of clients to configure the same bridge with multiple pluggable + transports. Fixes bug 21027; bugfix on 0.3.0.1-alpha. + + o Major bugfixes (hidden service directory v3): + - Stop crashing on a failed v3 hidden service descriptor lookup + failure. Fixes bug 21471; bugfixes on tor-0.3.0.1-alpha. + + o Major bugfixes (parsing): + - When parsing a malformed content-length field from an HTTP + message, do not read off the end of the buffer. This bug was a + potential remote denial-of-service attack against Tor clients and + relays. A workaround was released in October 2016, to prevent this + bug from crashing Tor. This is a fix for the underlying issue, + which should no longer matter (if you applied the earlier patch). + Fixes bug 20894; bugfix on 0.2.0.16-alpha. Bug found by fuzzing + using AFL (http://lcamtuf.coredump.cx/afl/). + - Fix an integer underflow bug when comparing malformed Tor + versions. This bug could crash Tor when built with + --enable-expensive-hardening, or on Tor 0.2.9.1-alpha through Tor + 0.2.9.8, which were built with -ftrapv by default. In other cases + it was harmless. Part of TROVE-2017-001. Fixes bug 21278; bugfix + on 0.0.8pre1. Found by OSS-Fuzz. + + o Minor feature (protocol versioning): + - Add new protocol version for proposal 224. HSIntro now advertises + version "3-4" and HSDir version "1-2". Fixes ticket 20656. + + o Minor features (directory authorities): + - Directory authorities now reject descriptors that claim to be + malformed versions of Tor. Helps prevent exploitation of + bug 21278. + - Reject version numbers with components that exceed INT32_MAX. + Otherwise 32-bit and 64-bit platforms would behave inconsistently. + Fixes bug 21450; bugfix on 0.0.8pre1. + + o Minor features (geoip): + - Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2 + Country database. + + o Minor features (reliability, crash): + - Try better to detect problems in buffers where they might grow (or + think they have grown) over 2 GB in size. Diagnostic for + bug 21369. + + o Minor features (testing): + - During 'make test-network-all', if tor logs any warnings, ask + chutney to output them. Requires a recent version of chutney with + the 21572 patch. Implements 21570. + + o Minor bugfixes (certificate expiration time): + - Avoid using link certificates that don't become valid till some + time in the future. Fixes bug 21420; bugfix on 0.2.4.11-alpha + + o Minor bugfixes (code correctness): + - Repair a couple of (unreachable or harmless) cases of the risky + comparison-by-subtraction pattern that caused bug 21278. + - Remove a redundant check for the UseEntryGuards option from the + options_transition_affects_guards() function. Fixes bug 21492; + bugfix on 0.3.0.1-alpha. + + o Minor bugfixes (directory mirrors): + - Allow relays to use directory mirrors without a DirPort: these + relays need to be contacted over their ORPorts using a begindir + connection. Fixes one case of bug 20711; bugfix on 0.2.8.2-alpha. + - Clarify the message logged when a remote relay is unexpectedly + missing an ORPort or DirPort: users were confusing this with a + local port. Fixes another case of bug 20711; bugfix + on 0.2.8.2-alpha. + + o Minor bugfixes (guards): + - Don't warn about a missing guard state on timeout-measurement + circuits: they aren't supposed to be using guards. Fixes an + instance of bug 21007; bugfix on 0.3.0.1-alpha. + - Silence a BUG() warning when attempting to use a guard whose + descriptor we don't know, and make this scenario less likely to + happen. Fixes bug 21415; bugfix on 0.3.0.1-alpha. + + o Minor bugfixes (hidden service): + - Pass correct buffer length when encoding legacy ESTABLISH_INTRO + cells. Previously, we were using sizeof() on a pointer, instead of + the real destination buffer. Fortunately, that value was only used + to double-check that there was enough room--which was already + enforced elsewhere. Fixes bug 21553; bugfix on 0.3.0.1-alpha. + + o Minor bugfixes (testing): + - Fix Raspbian build issues related to missing socket errno in + test_util.c. Fixes bug 21116; bugfix on tor-0.2.8.2. Patch + by "hein". + - Rename "make fuzz" to "make test-fuzz-corpora", since it doesn't + actually fuzz anything. Fixes bug 21447; bugfix on 0.3.0.3-alpha. + - Use bash in src/test/test-network.sh. This ensures we reliably + call chutney's newer tools/test-network.sh when available. Fixes + bug 21562; bugfix on 0.2.9.1-alpha. + + o Documentation: + - Small fixes to the fuzzing documentation. Closes ticket 21472. + + +Changes in version 0.2.9.10 - 2017-03-01 + Tor 0.2.9.10 backports a security fix from later Tor release. It also + includes fixes for some major issues affecting directory authorities, + LibreSSL compatibility, and IPv6 correctness. + + The Tor 0.2.9.x release series is now marked as a long-term-support + series. We intend to backport security fixes to 0.2.9.x until at + least January of 2020. + + o Major bugfixes (directory authority, 0.3.0.3-alpha): + - During voting, when marking a relay as a probable sybil, do not + clear its BadExit flag: sybils can still be bad in other ways + too. (We still clear the other flags.) Fixes bug 21108; bugfix + on 0.2.0.13-alpha. + + o Major bugfixes (IPv6 Exits, backport from 0.3.0.3-alpha): + - Stop rejecting all IPv6 traffic on Exits whose exit policy rejects + any IPv6 addresses. Instead, only reject a port over IPv6 if the + exit policy rejects that port on more than an IPv6 /16 of + addresses. This bug was made worse by 17027 in 0.2.8.1-alpha, + which rejected a relay's own IPv6 address by default. Fixes bug + 21357; bugfix on commit 004f3f4e53 in 0.2.4.7-alpha. + + o Major bugfixes (parsing, also in 0.3.0.4-rc): + - Fix an integer underflow bug when comparing malformed Tor + versions. This bug could crash Tor when built with + --enable-expensive-hardening, or on Tor 0.2.9.1-alpha through Tor + 0.2.9.8, which were built with -ftrapv by default. In other cases + it was harmless. Part of TROVE-2017-001. Fixes bug 21278; bugfix + on 0.0.8pre1. Found by OSS-Fuzz. + + o Minor features (directory authorities, also in 0.3.0.4-rc): + - Directory authorities now reject descriptors that claim to be + malformed versions of Tor. Helps prevent exploitation of + bug 21278. + - Reject version numbers with components that exceed INT32_MAX. + Otherwise 32-bit and 64-bit platforms would behave inconsistently. + Fixes bug 21450; bugfix on 0.0.8pre1. + + o Minor features (geoip): + - Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2 + Country database. + + o Minor features (portability, compilation, backport from 0.3.0.3-alpha): + - Autoconf now checks to determine if OpenSSL structures are opaque, + instead of explicitly checking for OpenSSL version numbers. Part + of ticket 21359. + - Support building with recent LibreSSL code that uses opaque + structures. Closes ticket 21359. + + o Minor bugfixes (code correctness, also in 0.3.0.4-rc): + - Repair a couple of (unreachable or harmless) cases of the risky + comparison-by-subtraction pattern that caused bug 21278. + + o Minor bugfixes (tor-resolve, backport from 0.3.0.3-alpha): + - The tor-resolve command line tool now rejects hostnames over 255 + characters in length. Previously, it would silently truncate them, + which could lead to bugs. Fixes bug 21280; bugfix on 0.0.9pre5. + Patch by "junglefowl".

If you want to see more detailed descriptions of the changes in each development snapshot, see the ChangeLog file. +Changes in version 0.3.0.13 - 2017-12-01 + Tor 0.3.0.13 backports important security and stability bugfixes from + later Tor releases. All Tor users should upgrade to this release, or + to another of the releases coming out today. + + Note: the Tor 0.3.0 series will no longer be supported after 26 Jan + 2018. If you need a release with long-term support, please stick with + the 0.2.9 series. Otherwise, please upgrade to 0.3.1 or later. + + o Major bugfixes (security, backport from 0.3.2.6-alpha): + - Fix a denial of service bug where an attacker could use a + malformed directory object to cause a Tor instance to pause while + OpenSSL would try to read a passphrase from the terminal. (Tor + instances run without a terminal, which is the case for most Tor + packages, are not impacted.) Fixes bug 24246; bugfix on every + version of Tor. Also tracked as TROVE-2017-011 and CVE-2017-8821. + Found by OSS-Fuzz as testcase 6360145429790720. + - Fix a denial of service issue where an attacker could crash a + directory authority using a malformed router descriptor. Fixes bug + 24245; bugfix on 0.2.9.4-alpha. Also tracked as TROVE-2017-010 + and CVE-2017-8820. + - When checking for replays in the INTRODUCE1 cell data for a + (legacy) onion service, correctly detect replays in the RSA- + encrypted part of the cell. We were previously checking for + replays on the entire cell, but those can be circumvented due to + the malleability of Tor's legacy hybrid encryption. This fix helps + prevent a traffic confirmation attack. Fixes bug 24244; bugfix on + 0.2.4.1-alpha. This issue is also tracked as TROVE-2017-009 + and CVE-2017-8819. + + o Major bugfixes (security, onion service v2, backport from 0.3.2.6-alpha): + - Fix a use-after-free error that could crash v2 Tor onion services + when they failed to open circuits while expiring introduction + points. Fixes bug 24313; bugfix on 0.2.7.2-alpha. This issue is + also tracked as TROVE-2017-013 and CVE-2017-8823. + + o Major bugfixes (security, relay, backport from 0.3.2.6-alpha): + - When running as a relay, make sure that we never build a path + through ourselves, even in the case where we have somehow lost the + version of our descriptor appearing in the consensus. Fixes part + of bug 21534; bugfix on 0.2.0.1-alpha. This issue is also tracked + as TROVE-2017-012 and CVE-2017-8822. + - When running as a relay, make sure that we never choose ourselves + as a guard. Fixes part of bug 21534; bugfix on 0.3.0.1-alpha. This + issue is also tracked as TROVE-2017-012 and CVE-2017-8822. + + o Major bugfixes (exit relays, DNS, backport from 0.3.2.4-alpha): + - Fix an issue causing DNS to fail on high-bandwidth exit nodes, + making them nearly unusable. 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 Minor features (security, windows, backport from 0.3.1.1-alpha): + - Enable a couple of pieces of Windows hardening: one + (HeapEnableTerminationOnCorruption) that has been on-by-default + since Windows 8, and unavailable before Windows 7; and one + (PROCESS_DEP_DISABLE_ATL_THUNK_EMULATION) which we believe doesn't + affect us, but shouldn't do any harm. Closes ticket 21953. + + o Minor features (bridge, backport from 0.3.1.9): + - Bridges now include notice in their descriptors that they are + bridges, and notice of their distribution status, based on their + publication settings. Implements ticket 18329. For more fine- + grained control of how a bridge is distributed, upgrade to 0.3.2.x + or later. + + o Minor features (directory authority, backport from 0.3.2.6-alpha): + - Add an IPv6 address for the "bastet" directory authority. Closes + ticket 24394. + + o Minor features (geoip): + - Update geoip and geoip6 to the November 6 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfix (relay address resolution, backport from 0.3.2.1-alpha): + - Avoid unnecessary calls to directory_fetches_from_authorities() on + relays, to prevent spurious address resolutions and descriptor + rebuilds. This is a mitigation for bug 21789. Fixes bug 23470; + bugfix on in 0.2.8.1-alpha. + + o Minor bugfixes (compilation, backport from 0.3.2.1-alpha): + - Fix unused variable warnings in donna's Curve25519 SSE2 code. + Fixes bug 22895; bugfix on 0.2.7.2-alpha. + + o Minor bugfixes (logging, relay shutdown, annoyance, backport from 0.3.2.2-alpha): + - When a circuit is marked for close, do not attempt to package any + cells for channels on that circuit. Previously, we would detect + this condition lower in the call stack, when we noticed that the + circuit had no attached channel, and log an annoying message. + Fixes bug 8185; bugfix on 0.2.5.4-alpha. + + o Minor bugfixes (relay, crash, backport from 0.3.2.4-alpha): + - 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, backport from 0.3.1.6-rc): + - Fix an undersized buffer in test-memwipe.c. Fixes bug 23291; + bugfix on 0.2.7.2-alpha. Found and patched by Ties Stuij. + + +Changes in version 0.3.0.12 - 2017-10-25 + Tor 0.3.0.12 backports a collection of bugfixes from later Tor release + series, including a bugfix for a crash issue that had affected relays + under memory pressure. It also adds a new directory authority, Bastet. + + Note: the Tor 0.3.0 series will no longer be supported after 26 Jan + 2018. If you need a release with long-term support, please stick with + the 0.2.9 series. Otherwise, please upgrade to 0.3.1 or later. + + o Directory authority changes: + - Add "Bastet" as a ninth directory authority to the default list. + Closes ticket 23910. + - The directory authority "Longclaw" has changed its IP address. + Closes ticket 23592. + + o Major bugfixes (relay, crash, assertion failure, backport from 0.3.2.2-alpha): + - Fix a timing-based assertion failure that could occur when the + circuit out-of-memory handler freed a connection's output buffer. + Fixes bug 23690; bugfix on 0.2.6.1-alpha. + + o Minor features (directory authorities, backport from 0.3.2.2-alpha): + - Remove longclaw's IPv6 address, as it will soon change. Authority + IPv6 addresses were originally added in 0.2.8.1-alpha. This leaves + 3/8 directory authorities with IPv6 addresses, but there are also + 52 fallback directory mirrors with IPv6 addresses. Resolves 19760. + + o Minor features (geoip): + - Update geoip and geoip6 to the October 4 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (directory authority, backport from 0.3.1.5-alpha): + - When a directory authority rejects a descriptor or extrainfo with + a given digest, mark that digest as undownloadable, so that we do + not attempt to download it again over and over. We previously + tried to avoid downloading such descriptors by other means, but we + didn't notice if we accidentally downloaded one anyway. This + behavior became problematic in 0.2.7.2-alpha, when authorities + began pinning Ed25519 keys. Fixes bug 22349; bugfix + on 0.2.1.19-alpha. + + o Minor bugfixes (hidden service, relay, backport from 0.3.2.2-alpha): + - Avoid a possible double close of a circuit by the intro point on + error of sending the INTRO_ESTABLISHED cell. Fixes bug 23610; + bugfix on 0.3.0.1-alpha. + + o Minor bugfixes (memory safety, backport from 0.3.2.3-alpha): + - Clear the address when node_get_prim_orport() returns early. + Fixes bug 23874; bugfix on 0.2.8.2-alpha. + + o Minor bugfixes (Windows service, backport from 0.3.1.6-rc): + - When running as a Windows service, set the ID of the main thread + correctly. Failure to do so made us fail to send log messages to + the controller in 0.2.1.16-rc, slowed down controller event + delivery in 0.2.7.3-rc and later, and crash with an assertion + failure in 0.3.1.1-alpha. Fixes bug 23081; bugfix on 0.2.1.6-alpha. + Patch and diagnosis from "Vort". + + +Changes in version 0.3.0.11 - 2017-09-18 + Tor 0.3.0.11 backports a collection of bugfixes from Tor the 0.3.1 + series. + + Most significantly, it includes a fix for TROVE-2017-008, a + security bug that affects hidden services running with the + SafeLogging option disabled. For more information, see + https://trac.torproject.org/projects/tor/ticket/23490 + + Note: now that Tor 0.3.1.x is stable and released, support for the + 0.3.0.x series will end on 26 Jan 2018. For longer term support, + either upgrade to the most recent 0.3.1.x release, or downgrade to + 0.2.9.x for long-term support. + + o Minor features (code style, backport from 0.3.1.7): + - Add "Falls through" comments to our codebase, in order to silence + GCC 7's -Wimplicit-fallthrough warnings. Patch from Andreas + Stieger. Closes ticket 22446. + + o Minor features: + - Update geoip and geoip6 to the September 6 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (compilation, backport from 0.3.1.7): + - Avoid compiler warnings in the unit tests for calling tor_sscanf() + with wide string outputs. Fixes bug 15582; bugfix on 0.2.6.2-alpha. + + o Minor bugfixes (controller, backport from 0.3.1.7): + - Do not crash when receiving a HSPOST command with an empty body. + Fixes part of bug 22644; bugfix on 0.2.7.1-alpha. + - Do not crash when receiving a POSTDESCRIPTOR command with an empty + body. Fixes part of bug 22644; bugfix on 0.2.0.1-alpha. + + o Minor bugfixes (file limits, osx, backport from 0.3.1.5-alpha): + - When setting the maximum number of connections allowed by the OS, + always allow some extra file descriptors for other files. Fixes + bug 22797; bugfix on 0.2.0.10-alpha. + + o Minor bugfixes (logging, relay, backport from 0.3.1.6-rc): + - Remove a forgotten debugging message when an introduction point + successfully establishes a hidden service prop224 circuit with + a client. + - Change three other log_warn() for an introduction point to + protocol warnings, because they can be failure from the network + and are not relevant to the operator. Fixes bug 23078; bugfix on + 0.3.0.1-alpha and 0.3.0.2-alpha. + + +Changes in version 0.3.0.10 - 2017-08-02 + Tor 0.3.0.10 backports a collection of small-to-medium bugfixes + from the current Tor alpha series. OpenBSD users and TPROXY users + should upgrade; others are probably okay sticking with 0.3.0.9. + + o Major features (build system, continuous integration, backport from 0.3.1.5-alpha): + - Tor's repository now includes a Travis Continuous Integration (CI) + configuration file (.travis.yml). This is meant to help new + developers and contributors who fork Tor to a Github repository be + better able to test their changes, and understand what we expect + to pass. To use this new build feature, you must fork Tor to your + Github account, then go into the "Integrations" menu in the + repository settings for your fork and enable Travis, then push + your changes. Closes ticket 22636. + + o Major bugfixes (linux TPROXY support, backport from 0.3.1.1-alpha): + - Fix a typo that had prevented TPROXY-based transparent proxying + from working under Linux. Fixes bug 18100; bugfix on 0.2.6.3-alpha. + Patch from "d4fq0fQAgoJ". + + o Major bugfixes (openbsd, denial-of-service, backport from 0.3.1.5-alpha): + - Avoid an assertion failure bug affecting our implementation of + inet_pton(AF_INET6) on certain OpenBSD systems whose strtol() + handling of "0xfoo" differs from what we had expected. Fixes bug + 22789; bugfix on 0.2.3.8-alpha. Also tracked as TROVE-2017-007. + + o Minor features (backport from 0.3.1.5-alpha): + - Update geoip and geoip6 to the July 4 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (bandwidth accounting, backport from 0.3.1.2-alpha): + - Roll over monthly accounting at the configured hour and minute, + rather than always at 00:00. Fixes bug 22245; bugfix on 0.0.9rc1. + Found by Andrey Karpov with PVS-Studio. + + o Minor bugfixes (compilation warnings, backport from 0.3.1.5-alpha): + - Suppress -Wdouble-promotion warnings with clang 4.0. Fixes bug 22915; + bugfix on 0.2.8.1-alpha. + - Fix warnings when building with libscrypt and openssl scrypt + support on Clang. Fixes bug 22916; bugfix on 0.2.7.2-alpha. + - When building with certain versions of the mingw C header files, + avoid float-conversion warnings when calling the C functions + isfinite(), isnan(), and signbit(). Fixes bug 22801; bugfix + on 0.2.8.1-alpha. + + o Minor bugfixes (compilation, mingw, backport from 0.3.1.1-alpha): + - Backport a fix for an "unused variable" warning that appeared + in some versions of mingw. Fixes bug 22838; bugfix on + 0.2.8.1-alpha. + + o Minor bugfixes (coverity build support, backport from 0.3.1.5-alpha): + - Avoid Coverity build warnings related to our BUG() macro. By + default, Coverity treats BUG() as the Linux kernel does: an + instant abort(). We need to override that so our BUG() macro + doesn't prevent Coverity from analyzing functions that use it. + Fixes bug 23030; bugfix on 0.2.9.1-alpha. + + o Minor bugfixes (directory authority, backport from 0.3.1.1-alpha): + - When rejecting a router descriptor for running an obsolete version + of Tor without ntor support, warn about the obsolete tor version, + not the missing ntor key. Fixes bug 20270; bugfix on 0.2.9.3-alpha. + + o Minor bugfixes (linux seccomp2 sandbox, backport from 0.3.1.5-alpha): + - Avoid a sandbox failure when trying to re-bind to a socket and + mark it as IPv6-only. Fixes bug 20247; bugfix on 0.2.5.1-alpha. + + o Minor bugfixes (unit tests, backport from 0.3.1.5-alpha) + - Fix a memory leak in the link-handshake/certs_ok_ed25519 test. + Fixes bug 22803; bugfix on 0.3.0.1-alpha. + + +Changes in version 0.3.0.9 - 2017-06-29 + Tor 0.3.0.9 fixes a path selection bug that would allow a client + to use a guard that was in the same network family as a chosen exit + relay. This is a security regression; all clients running earlier + versions of 0.3.0.x or 0.3.1.x should upgrade to 0.3.0.9 or + 0.3.1.4-alpha. + + This release also backports several other bugfixes from the 0.3.1.x + series. + + o Major bugfixes (path selection, security, backport from 0.3.1.4-alpha): + - When choosing which guard to use for a circuit, avoid the exit's + family along with the exit itself. Previously, the new guard + selection logic avoided the exit, but did not consider its family. + Fixes bug 22753; bugfix on 0.3.0.1-alpha. Tracked as TROVE-2017- + 006 and CVE-2017-0377. + + o Major bugfixes (entry guards, backport from 0.3.1.1-alpha): + - Don't block bootstrapping when a primary bridge is offline and we + can't get its descriptor. Fixes bug 22325; fixes one case of bug + 21969; bugfix on 0.3.0.3-alpha. + + o Major bugfixes (entry guards, backport from 0.3.1.4-alpha): + - When starting with an old consensus, do not add new entry guards + unless the consensus is "reasonably live" (under 1 day old). Fixes + one root cause of bug 22400; bugfix on 0.3.0.1-alpha. + + o Minor features (geoip): + - Update geoip and geoip6 to the June 8 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (voting consistency, backport from 0.3.1.1-alpha): + - Reject version numbers with non-numeric prefixes (such as +, -, or + whitespace). Disallowing whitespace prevents differential version + parsing between POSIX-based and Windows platforms. Fixes bug 21507 + and part of 21508; bugfix on 0.0.8pre1. + + o Minor bugfixes (linux seccomp2 sandbox, backport from 0.3.1.4-alpha): + - Permit the fchmod system call, to avoid crashing on startup when + starting with the seccomp2 sandbox and an unexpected set of + permissions on the data directory or its contents. Fixes bug + 22516; bugfix on 0.2.5.4-alpha. + + o Minor bugfixes (defensive programming, backport from 0.3.1.4-alpha): + - Fix a memset() off the end of an array when packing cells. This + bug should be harmless in practice, since the corrupted bytes are + still in the same structure, and are always padding bytes, + ignored, or immediately overwritten, depending on compiler + behavior. Nevertheless, because the memset()'s purpose is to make + sure that any other cell-handling bugs can't expose bytes to the + network, we need to fix it. Fixes bug 22737; bugfix on + 0.2.4.11-alpha. Fixes CID 1401591. + + +Changes in version 0.3.0.8 - 2017-06-08 + Tor 0.3.0.8 fixes a pair of bugs that would allow an attacker to + remotely crash a hidden service with an assertion failure. Anyone + running a hidden service should upgrade to this version, or to some + other version with fixes for TROVE-2017-004 and TROVE-2017-005. + + Tor 0.3.0.8 also includes fixes for several key management bugs + that sometimes made relays unreliable, as well as several other + bugfixes described below. + + o Major bugfixes (hidden service, relay, security, backport + from 0.3.1.3-alpha): + - Fix a remotely triggerable assertion failure when a hidden service + handles a malformed BEGIN cell. Fixes bug 22493, tracked as + TROVE-2017-004 and as CVE-2017-0375; bugfix on 0.3.0.1-alpha. + - Fix a remotely triggerable assertion failure caused by receiving a + BEGIN_DIR cell on a hidden service rendezvous circuit. Fixes bug + 22494, tracked as TROVE-2017-005 and CVE-2017-0376; bugfix + on 0.2.2.1-alpha. + + o Major bugfixes (relay, link handshake, backport from 0.3.1.3-alpha): + - When performing the v3 link handshake on a TLS connection, report + that we have the x509 certificate that we actually used on that + connection, even if we have changed certificates since that + connection was first opened. Previously, we would claim to have + used our most recent x509 link certificate, which would sometimes + make the link handshake fail. Fixes one case of bug 22460; bugfix + on 0.2.3.6-alpha. + + o Major bugfixes (relays, key management, backport from 0.3.1.3-alpha): + - Regenerate link and authentication certificates whenever the key + that signs them changes; also, regenerate link certificates + whenever the signed key changes. Previously, these processes were + only weakly coupled, and we relays could (for minutes to hours) + wind up with an inconsistent set of keys and certificates, which + other relays would not accept. Fixes two cases of bug 22460; + bugfix on 0.3.0.1-alpha. + - When sending an Ed25519 signing->link certificate in a CERTS cell, + send the certificate that matches the x509 certificate that we + used on the TLS connection. Previously, there was a race condition + if the TLS context rotated after we began the TLS handshake but + before we sent the CERTS cell. Fixes a case of bug 22460; bugfix + on 0.3.0.1-alpha. + + o Major bugfixes (hidden service v3, backport from 0.3.1.1-alpha): + - Stop rejecting v3 hidden service descriptors because their size + did not match an old padding rule. Fixes bug 22447; bugfix on + tor-0.3.0.1-alpha. + + o Minor features (fallback directory list, backport from 0.3.1.3-alpha): + - Replace the 177 fallbacks originally introduced in Tor 0.2.9.8 in + December 2016 (of which ~126 were still functional) with a list of + 151 fallbacks (32 new, 119 unchanged, 58 removed) generated in May + 2017. Resolves ticket 21564. + + o Minor bugfixes (configuration, backport from 0.3.1.1-alpha): + - Do not crash when starting with LearnCircuitBuildTimeout 0. Fixes + bug 22252; bugfix on 0.2.9.3-alpha. + + o Minor bugfixes (correctness, backport from 0.3.1.3-alpha): + - Avoid undefined behavior when parsing IPv6 entries from the geoip6 + file. Fixes bug 22490; bugfix on 0.2.4.6-alpha. + + o Minor bugfixes (link handshake, backport from 0.3.1.3-alpha): + - Lower the lifetime of the RSA->Ed25519 cross-certificate to six + months, and regenerate it when it is within one month of expiring. + Previously, we had generated this certificate at startup with a + ten-year lifetime, but that could lead to weird behavior when Tor + was started with a grossly inaccurate clock. Mitigates bug 22466; + mitigation on 0.3.0.1-alpha. + + o Minor bugfixes (memory leak, directory authority, backport from + 0.3.1.2-alpha): + - When directory authorities reject a router descriptor due to + keypinning, free the router descriptor rather than leaking the + memory. Fixes bug 22370; bugfix on 0.2.7.2-alpha. + + +Changes in version 0.3.0.7 - 2017-05-15 + Tor 0.3.0.7 fixes a medium-severity security bug in earlier versions + of Tor 0.3.0.x, where an attacker could cause a Tor relay process + to exit. Relays running earlier versions of Tor 0.3.0.x should upgrade; + clients are not affected. + + o Major bugfixes (hidden service directory, security): + - Fix an assertion failure in the hidden service directory code, which + could be used by an attacker to remotely cause a Tor relay process to + exit. Relays running earlier versions of Tor 0.3.0.x should upgrade. + should upgrade. This security issue is tracked as TROVE-2017-002. + Fixes bug 22246; bugfix on 0.3.0.1-alpha. + + o Minor features: + - Update geoip and geoip6 to the May 2 2017 Maxmind GeoLite2 + Country database. + + o Minor features (future-proofing): + - Tor no longer refuses to download microdescriptors or descriptors + if they are listed as "published in the future". This change will + eventually allow us to stop listing meaningful "published" dates + in microdescriptor consensuses, and thereby allow us to reduce the + resources required to download consensus diffs by over 50%. + Implements part of ticket 21642; implements part of proposal 275. + + o Minor bugfixes (Linux seccomp2 sandbox): + - The getpid() system call is now permitted under the Linux seccomp2 + sandbox, to avoid crashing with versions of OpenSSL (and other + libraries) that attempt to learn the process's PID by using the + syscall rather than the VDSO code. Fixes bug 21943; bugfix + on 0.2.5.1-alpha. + + +Changes in version 0.3.0.6 - 2017-04-26 + Tor 0.3.0.6 is the first stable release of the Tor 0.3.0 series. + + With the 0.3.0 series, clients and relays now use Ed25519 keys to + authenticate their link connections to relays, rather than the old + RSA1024 keys that they used before. (Circuit crypto has been + Curve25519-authenticated since 0.2.4.8-alpha.) We have also replaced + the guard selection and replacement algorithm to behave more robustly + in the presence of unreliable networks, and to resist guard- + capture attacks. + + This series also includes numerous other small features and bugfixes, + along with more groundwork for the upcoming hidden-services revamp. + + Per our stable release policy, we plan to support the Tor 0.3.0 + release series for at least the next nine months, or for three months + after the first stable release of the 0.3.1 series: whichever is + longer. If you need a release with long-term support, we recommend + that you stay with the 0.2.9 series. + + Below are the changes since 0.2.9.10. For a list of only the changes + since 0.3.0.5-rc, see the ChangeLog file. + + o Major features (directory authority, security): + - The default for AuthDirPinKeys is now 1: directory authorities + will reject relays where the RSA identity key matches a previously + seen value, but the Ed25519 key has changed. Closes ticket 18319. + + o Major features (guard selection algorithm): + - Tor's guard selection algorithm has been redesigned from the + ground up, to better support unreliable networks and restrictive + sets of entry nodes, and to better resist guard-capture attacks by + hostile local networks. Implements proposal 271; closes + ticket 19877. + + o Major features (next-generation hidden services): + - Relays can now handle v3 ESTABLISH_INTRO cells as specified by + prop224 aka "Next Generation Hidden Services". Service and clients + don't use this functionality yet. Closes ticket 19043. Based on + initial code by Alec Heifetz. + - Relays now support the HSDir version 3 protocol, so that they can + can store and serve v3 descriptors. This is part of the next- + generation onion service work detailled in proposal 224. Closes + ticket 17238. + + o Major features (protocol, ed25519 identity keys): + - Clients now support including Ed25519 identity keys in the EXTEND2 + cells they generate. By default, this is controlled by a consensus + parameter, currently disabled. You can turn this feature on for + testing by setting ExtendByEd25519ID in your configuration. This + might make your traffic appear different than the traffic + generated by other users, however. Implements part of ticket + 15056; part of proposal 220. + - Relays now understand requests to extend to other relays by their + Ed25519 identity keys. When an Ed25519 identity key is included in + an EXTEND2 cell, the relay will only extend the circuit if the + other relay can prove ownership of that identity. Implements part + of ticket 15056; part of proposal 220. + - Relays now use Ed25519 to prove their Ed25519 identities and to + one another, and to clients. This algorithm is faster and more + secure than the RSA-based handshake we've been doing until now. + Implements the second big part of proposal 220; Closes + ticket 15055. + + o Major features (security): + - Change the algorithm used to decide DNS TTLs on client and server + side, to better resist DNS-based correlation attacks like the + DefecTor attack of Greschbach, Pulls, Roberts, Winter, and + Feamster. Now relays only return one of two possible DNS TTL + values, and clients are willing to believe DNS TTL values up to 3 + hours long. Closes ticket 19769. + + o Major bugfixes (client, onion service, also in 0.2.9.9): + - Fix a client-side onion service reachability bug, where multiple + socks requests to an onion service (or a single slow request) + could cause us to mistakenly mark some of the service's + introduction points as failed, and we cache that failure so + eventually we run out and can't reach the service. Also resolves a + mysterious "Remote server sent bogus reason code 65021" log + warning. The bug was introduced in ticket 17218, where we tried to + remember the circuit end reason as a uint16_t, which mangled + negative values. Partially fixes bug 21056 and fixes bug 20307; + bugfix on 0.2.8.1-alpha. + + o Major bugfixes (crash, directory connections): + - Fix a rare crash when sending a begin cell on a circuit whose + linked directory connection had already been closed. Fixes bug + 21576; bugfix on 0.2.9.3-alpha. Reported by Alec Muffett. + + o Major bugfixes (directory authority): + - During voting, when marking a relay as a probable sybil, do not + clear its BadExit flag: sybils can still be bad in other ways + too. (We still clear the other flags.) Fixes bug 21108; bugfix + on 0.2.0.13-alpha. + + o Major bugfixes (DNS): + - Fix a bug that prevented exit nodes from caching DNS records for + more than 60 seconds. Fixes bug 19025; bugfix on 0.2.4.7-alpha. + + o Major bugfixes (IPv6 Exits): + - Stop rejecting all IPv6 traffic on Exits whose exit policy rejects + any IPv6 addresses. Instead, only reject a port over IPv6 if the + exit policy rejects that port on more than an IPv6 /16 of + addresses. This bug was made worse by 17027 in 0.2.8.1-alpha, + which rejected a relay's own IPv6 address by default. Fixes bug + 21357; bugfix on commit 004f3f4e53 in 0.2.4.7-alpha. + + o Major bugfixes (parsing): + - Fix an integer underflow bug when comparing malformed Tor + versions. This bug could crash Tor when built with + --enable-expensive-hardening, or on Tor 0.2.9.1-alpha through Tor + 0.2.9.8, which were built with -ftrapv by default. In other cases + it was harmless. Part of TROVE-2017-001. Fixes bug 21278; bugfix + on 0.0.8pre1. Found by OSS-Fuzz. + - When parsing a malformed content-length field from an HTTP + message, do not read off the end of the buffer. This bug was a + potential remote denial-of-service attack against Tor clients and + relays. A workaround was released in October 2016, to prevent this + bug from crashing Tor. This is a fix for the underlying issue, + which should no longer matter (if you applied the earlier patch). + Fixes bug 20894; bugfix on 0.2.0.16-alpha. Bug found by fuzzing + using AFL (http://lcamtuf.coredump.cx/afl/). + + o Major bugfixes (scheduler): + - Actually compare circuit policies in ewma_cmp_cmux(). This bug + caused the channel scheduler to behave more or less randomly, + rather than preferring channels with higher-priority circuits. + Fixes bug 20459; bugfix on 0.2.6.2-alpha. + + o Major bugfixes (security, also in 0.2.9.9): + - Downgrade the "-ftrapv" option from "always on" to "only on when + --enable-expensive-hardening is provided." This hardening option, + like others, can turn survivable bugs into crashes--and having it + on by default made a (relatively harmless) integer overflow bug + into a denial-of-service bug. Fixes bug 21278 (TROVE-2017-001); + bugfix on 0.2.9.1-alpha. + + o Minor feature (client): + - Enable IPv6 traffic on the SocksPort by default. To disable this, + a user will have to specify "NoIPv6Traffic". Closes ticket 21269. + + o Minor feature (fallback scripts): + - Add a check_existing mode to updateFallbackDirs.py, which checks + if fallbacks in the hard-coded list are working. Closes ticket + 20174. Patch by haxxpop. + + o Minor feature (protocol versioning): + - Add new protocol version for proposal 224. HSIntro now advertises + version "3-4" and HSDir version "1-2". Fixes ticket 20656. + + o Minor features (ciphersuite selection): + - Allow relays to accept a wider range of ciphersuites, including + chacha20-poly1305 and AES-CCM. Closes the other part of 15426. + - Clients now advertise a list of ciphersuites closer to the ones + preferred by Firefox. Closes part of ticket 15426. + + o Minor features (controller): + - Add "GETINFO sr/current" and "GETINFO sr/previous" keys, to expose + shared-random values to the controller. Closes ticket 19925. + - When HSFETCH arguments cannot be parsed, say "Invalid argument" + rather than "unrecognized." Closes ticket 20389; patch from + Ivan Markin. + + o Minor features (controller, configuration): + - Each of the *Port options, such as SocksPort, ORPort, ControlPort, + and so on, now comes with a __*Port variant that will not be saved + to the torrc file by the controller's SAVECONF command. This + change allows TorBrowser to set up a single-use domain socket for + each time it launches Tor. Closes ticket 20956. + - The GETCONF command can now query options that may only be + meaningful in context-sensitive lists. This allows the controller + to query the mixed SocksPort/__SocksPort style options introduced + in feature 20956. Implements ticket 21300. + + o Minor features (diagnostic, directory client): + - Warn when we find an unexpected inconsistency in directory + download status objects. Prevents some negative consequences of + bug 20593. + + o Minor features (directory authorities): + - Directory authorities now reject descriptors that claim to be + malformed versions of Tor. Helps prevent exploitation of + bug 21278. + - Reject version numbers with components that exceed INT32_MAX. + Otherwise 32-bit and 64-bit platforms would behave inconsistently. + Fixes bug 21450; bugfix on 0.0.8pre1. + + o Minor features (directory authority): + - Add a new authority-only AuthDirTestEd25519LinkKeys option (on by + default) to control whether authorities should try to probe relays + by their Ed25519 link keys. This option will go away in a few + releases--unless we encounter major trouble in our ed25519 link + protocol rollout, in which case it will serve as a safety option. + + o Minor features (directory cache): + - Relays and bridges will now refuse to serve the consensus they + have if they know it is too old for a client to use. Closes + ticket 20511. + + o Minor features (ed25519 link handshake): + - Advertise support for the ed25519 link handshake using the + subprotocol-versions mechanism, so that clients can tell which + relays can identity themselves by Ed25519 ID. Closes ticket 20552. + + o Minor features (entry guards): + - Add UseEntryGuards to TEST_OPTIONS_DEFAULT_VALUES in order to not + break regression tests. + - Require UseEntryGuards when UseBridges is set, in order to make + sure bridges aren't bypassed. Resolves ticket 20502. + + o Minor features (fallback directories): + - Allow 3 fallback relays per operator, which is safe now that we + are choosing 200 fallback relays. Closes ticket 20912. + - Annotate updateFallbackDirs.py with the bandwidth and consensus + weight for each candidate fallback. Closes ticket 20878. + - Display the relay fingerprint when downloading consensuses from + fallbacks. Closes ticket 20908. + - Exclude relays affected by bug 20499 from the fallback list. + Exclude relays from the fallback list if they are running versions + known to be affected by bug 20499, or if in our tests they deliver + a stale consensus (i.e. one that expired more than 24 hours ago). + Closes ticket 20539. + - Make it easier to change the output sort order of fallbacks. + Closes ticket 20822. + - Reduce the minimum fallback bandwidth to 1 MByte/s. Part of + ticket 18828. + - Require fallback directories to have the same address and port for + 7 days (now that we have enough relays with this stability). + Relays whose OnionOO stability timer is reset on restart by bug + 18050 should upgrade to Tor 0.2.8.7 or later, which has a fix for + this issue. Closes ticket 20880; maintains short-term fix + in 0.2.8.2-alpha. + - Require fallbacks to have flags for 90% of the time (weighted + decaying average), rather than 95%. This allows at least 73% of + clients to bootstrap in the first 5 seconds without contacting an + authority. Part of ticket 18828. + - Select 200 fallback directories for each release. Closes + ticket 20881. + + o Minor features (fingerprinting resistence, authentication): + - Extend the length of RSA keys used for TLS link authentication to + 2048 bits. (These weren't used for forward secrecy; for forward + secrecy, we used P256.) Closes ticket 13752. + + o Minor features (geoip): + - Update geoip and geoip6 to the April 4 2017 Maxmind GeoLite2 + Country database. + + o Minor features (geoip, also in 0.2.9.9): + - Update geoip and geoip6 to the January 4 2017 Maxmind GeoLite2 + Country database. + + o Minor features (infrastructure): + - Implement smartlist_add_strdup() function. Replaces the use of + smartlist_add(sl, tor_strdup(str)). Closes ticket 20048. + + o Minor features (linting): + - Enhance the changes file linter to warn on Tor versions that are + prefixed with "tor-". Closes ticket 21096. + + o Minor features (logging): + - In several places, describe unset ed25519 keys as "<unset>", + rather than the scary "AAAAAAAA...AAA". Closes ticket 21037. + + o Minor features (portability, compilation): + - Autoconf now checks to determine if OpenSSL structures are opaque, + instead of explicitly checking for OpenSSL version numbers. Part + of ticket 21359. + - Support building with recent LibreSSL code that uses opaque + structures. Closes ticket 21359. + + o Minor features (relay): + - We now allow separation of exit and relay traffic to different + source IP addresses, using the OutboundBindAddressExit and + OutboundBindAddressOR options respectively. Closes ticket 17975. + Written by Michael Sonntag. + + o Minor features (reliability, crash): + - Try better to detect problems in buffers where they might grow (or + think they have grown) over 2 GB in size. Diagnostic for + bug 21369. + + o Minor features (testing): + - During 'make test-network-all', if tor logs any warnings, ask + chutney to output them. Requires a recent version of chutney with + the 21572 patch. Implements 21570. + + o Minor bugfix (control protocol): + - The reply to a "GETINFO config/names" request via the control + protocol now spells the type "Dependent" correctly. This is a + breaking change in the control protocol. (The field seems to be + ignored by the most common known controllers.) Fixes bug 18146; + bugfix on 0.1.1.4-alpha. + - The GETINFO extra-info/digest/<digest> command was broken because + of a wrong base16 decode return value check, introduced when + refactoring that API. Fixes bug 22034; bugfix on 0.2.9.1-alpha. + + o Minor bugfix (logging): + - Don't recommend the use of Tor2web in non-anonymous mode. + Recommending Tor2web is a bad idea because the client loses all + anonymity. Tor2web should only be used in specific cases by users + who *know* and understand the issues. Fixes bug 21294; bugfix + on 0.2.9.3-alpha. + + o Minor bugfixes (bug resilience): + - Fix an unreachable size_t overflow in base64_decode(). Fixes bug + 19222; bugfix on 0.2.0.9-alpha. Found by Guido Vranken; fixed by + Hans Jerry Illikainen. + + o Minor bugfixes (build): + - Replace obsolete Autoconf macros with their modern equivalent and + prevent similar issues in the future. Fixes bug 20990; bugfix + on 0.1.0.1-rc. + + o Minor bugfixes (certificate expiration time): + - Avoid using link certificates that don't become valid till some + time in the future. Fixes bug 21420; bugfix on 0.2.4.11-alpha + + o Minor bugfixes (client): + - Always recover from failures in extend_info_from_node(), in an + attempt to prevent any recurrence of bug 21242. Fixes bug 21372; + bugfix on 0.2.3.1-alpha. + - When clients that use bridges start up with a cached consensus on + disk, they were ignoring it and downloading a new one. Now they + use the cached one. Fixes bug 20269; bugfix on 0.2.3.12-alpha. + + o Minor bugfixes (code correctness): + - Repair a couple of (unreachable or harmless) cases of the risky + comparison-by-subtraction pattern that caused bug 21278. + + o Minor bugfixes (config): + - Don't assert on startup when trying to get the options list and + LearnCircuitBuildTimeout is set to 0: we are currently parsing the + options so of course they aren't ready yet. Fixes bug 21062; + bugfix on 0.2.9.3-alpha. + + o Minor bugfixes (configuration): + - Accept non-space whitespace characters after the severity level in + the `Log` option. Fixes bug 19965; bugfix on 0.2.1.1-alpha. + - Support "TByte" and "TBytes" units in options given in bytes. + "TB", "terabyte(s)", "TBit(s)" and "terabit(s)" were already + supported. Fixes bug 20622; bugfix on 0.2.0.14-alpha. + + o Minor bugfixes (configure, autoconf): + - Rename the configure option --enable-expensive-hardening to + --enable-fragile-hardening. Expensive hardening makes the tor + daemon abort when some kinds of issues are detected. Thus, it + makes tor more at risk of remote crashes but safer against RCE or + heartbleed bug category. We now try to explain this issue in a + message from the configure script. Fixes bug 21290; bugfix + on 0.2.5.4-alpha. + + o Minor bugfixes (consensus weight): + - Add new consensus method that initializes bw weights to 1 instead + of 0. This prevents a zero weight from making it all the way to + the end (happens in small testing networks) and causing an error. + Fixes bug 14881; bugfix on 0.2.2.17-alpha. + + o Minor bugfixes (crash prevention): + - Fix an (currently untriggerable, but potentially dangerous) crash + bug when base32-encoding inputs whose sizes are not a multiple of + 5. Fixes bug 21894; bugfix on 0.2.9.1-alpha. + + o Minor bugfixes (dead code): + - Remove a redundant check for PidFile changes at runtime in + options_transition_allowed(): this check is already performed + regardless of whether the sandbox is active. Fixes bug 21123; + bugfix on 0.2.5.4-alpha. + + o Minor bugfixes (descriptors): + - Correctly recognise downloaded full descriptors as valid, even + when using microdescriptors as circuits. This affects clients with + FetchUselessDescriptors set, and may affect directory authorities. + Fixes bug 20839; bugfix on 0.2.3.2-alpha. + + o Minor bugfixes (directory mirrors): + - Allow relays to use directory mirrors without a DirPort: these + relays need to be contacted over their ORPorts using a begindir + connection. Fixes one case of bug 20711; bugfix on 0.2.8.2-alpha. + - Clarify the message logged when a remote relay is unexpectedly + missing an ORPort or DirPort: users were confusing this with a + local port. Fixes another case of bug 20711; bugfix + on 0.2.8.2-alpha. + + o Minor bugfixes (directory system): + - Bridges and relays now use microdescriptors (like clients do) + rather than old-style router descriptors. Now bridges will blend + in with clients in terms of the circuits they build. Fixes bug + 6769; bugfix on 0.2.3.2-alpha. + - Download all consensus flavors, descriptors, and authority + certificates when FetchUselessDescriptors is set, regardless of + whether tor is a directory cache or not. Fixes bug 20667; bugfix + on all recent tor versions. + + o Minor bugfixes (documentation): + - Update the tor manual page to document every option that can not + be changed while tor is running. Fixes bug 21122. + + o Minor bugfixes (ed25519 certificates): + - Correctly interpret ed25519 certificates that would expire some + time after 19 Jan 2038. Fixes bug 20027; bugfix on 0.2.7.2-alpha. + + o Minor bugfixes (fallback directories): + - Avoid checking fallback candidates' DirPorts if they are down in + OnionOO. When a relay operator has multiple relays, this + prioritizes relays that are up over relays that are down. Fixes + bug 20926; bugfix on 0.2.8.3-alpha. + - Stop failing when OUTPUT_COMMENTS is True in updateFallbackDirs.py. + Fixes bug 20877; bugfix on 0.2.8.3-alpha. + - Stop failing when a relay has no uptime data in + updateFallbackDirs.py. Fixes bug 20945; bugfix on 0.2.8.1-alpha. + + o Minor bugfixes (hidden service): + - Clean up the code for expiring intro points with no associated + circuits. It was causing, rarely, a service with some expiring + introduction points to not open enough additional introduction + points. Fixes part of bug 21302; bugfix on 0.2.7.2-alpha. + - Resolve two possible underflows which could lead to creating and + closing a lot of introduction point circuits in a non-stop loop. + Fixes bug 21302; bugfix on 0.2.7.2-alpha. + - Stop setting the torrc option HiddenServiceStatistics to "0" just + because we're not a bridge or relay. Instead, we preserve whatever + value the user set (or didn't set). Fixes bug 21150; bugfix + on 0.2.6.2-alpha. + + o Minor bugfixes (hidden services): + - Make hidden services check for failed intro point connections, + even when they have exceeded their intro point creation limit. + Fixes bug 21596; bugfix on 0.2.7.2-alpha. Reported by Alec Muffett. + - Make hidden services with 8 to 10 introduction points check for + failed circuits immediately after startup. Previously, they would + wait for 5 minutes before performing their first checks. Fixes bug + 21594; bugfix on 0.2.3.9-alpha. Reported by Alec Muffett. + - Stop ignoring misconfigured hidden services. Instead, refuse to + start tor until the misconfigurations have been corrected. Fixes + bug 20559; bugfix on multiple commits in 0.2.7.1-alpha + and earlier. + + o Minor bugfixes (IPv6): + - Make IPv6-using clients try harder to find an IPv6 directory + server. Fixes bug 20999; bugfix on 0.2.8.2-alpha. + - When IPv6 addresses have not been downloaded yet (microdesc + consensus documents don't list relay IPv6 addresses), use hard- + coded addresses for authorities, fallbacks, and configured + bridges. Now IPv6-only clients can use microdescriptors. Fixes bug + 20996; bugfix on b167e82 from 19608 in 0.2.8.5-alpha. + + o Minor bugfixes (memory leak at exit): + - Fix a small harmless memory leak at exit of the previously unused + RSA->Ed identity cross-certificate. Fixes bug 17779; bugfix + on 0.2.7.2-alpha. + + o Minor bugfixes (onion services): + - Allow the number of introduction points to be as low as 0, rather + than as low as 3.
