Anyone + running a hidden service should upgrade to this version, or to some + other version with fixes for TROVE-2017-005. (Versions before 0.3.0 + are not affected by TROVE-2017-004.) + + o Major bugfixes (hidden service, relay, security): + - 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 Minor features (geoip): + - Update geoip and geoip6 to the May 2 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (correctness): + - Avoid undefined behavior when parsing IPv6 entries from the geoip6 + file. Fixes bug 22490; bugfix on 0.2.4.6-alpha. + + +Changes in version 0.2.6.11 - 2017-03-03 + Tor 0.2.6.11 backports a number of security fixes from later Tor + releases. Anybody running Tor 0.2.6.10 or earlier should upgrade to + this release, if for some reason they cannot upgrade to a later + release series. + + Note that support for Tor 0.2.6.x is ending this year: we will not issue + any fixes for the Tor 0.2.6.x series after 1 August 2017. If you need + a Tor release series with longer-term support, we recommend Tor 0.2.9.x. + + o Directory authority changes (backport from 0.2.8.5-rc): + - Urras is no longer a directory authority. Closes ticket 19271. + + o Directory authority changes (backport from 0.2.9.2-alpha): + - The "Tonga" bridge authority has been retired; the new bridge + authority is "Bifroest". Closes tickets 19728 and 19690. + + o Directory authority key updates (backport from 0.2.8.1-alpha): + - Update the V3 identity key for the dannenberg directory authority: + it was changed on 18 November 2015. Closes task 17906. Patch + by "teor". + + o Major features (security fixes, backport from 0.2.9.4-alpha): + - Prevent a class of security bugs caused by treating the contents + of a buffer chunk as if they were a NUL-terminated string. At + least one such bug seems to be present in all currently used + versions of Tor, and would allow an attacker to remotely crash + most Tor instances, especially those compiled with extra compiler + hardening. With this defense in place, such bugs can't crash Tor, + though we should still fix them as they occur. Closes ticket + 20384 (TROVE-2016-10-001). + + o Major bugfixes (parsing, security, backport from 0.2.9.8): + - Fix a bug in parsing that could cause clients to read a single + byte past the end of an allocated region. This bug could be used + to cause hardened clients (built with --enable-expensive-hardening) + to crash if they tried to visit a hostile hidden service. Non- + hardened clients are only affected depending on the details of + their platform's memory allocator. Fixes bug 21018; bugfix on + 0.2.0.8-alpha. Found by using libFuzzer. Also tracked as TROVE- + 2016-12-002 and as CVE-2016-1254. + + o Major bugfixes (security, client, DNS proxy, backport from 0.2.8.3-alpha): + - 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, correctness, backport from 0.2.7.4-rc): + - Fix an error that could cause us to read 4 bytes before the + beginning of an openssl string. This bug could be used to cause + Tor to crash on systems with unusual malloc implementations, or + systems with unusual hardening installed. Fixes bug 17404; bugfix + on 0.2.3.6-alpha. + + o Major bugfixes (security, pointers, backport from 0.2.8.2-alpha): + - Avoid a difficult-to-trigger heap corruption attack when extending + a smartlist to contain over 16GB of pointers. Fixes bug 18162; + bugfix on 0.1.1.11-alpha, which fixed a related bug incompletely. + Reported by Guido Vranken. + + o Major bugfixes (dns proxy mode, crash, backport from 0.2.8.2-alpha): + - Avoid crashing when running as a DNS proxy. Fixes bug 16248; + bugfix on 0.2.0.1-alpha. Patch from "cypherpunks". + + o Major bugfixes (guard selection, backport from 0.2.7.6): + - Actually look at the Guard flag when selecting a new directory + guard. When we implemented the directory guard design, we + accidentally started treating all relays as if they have the Guard + flag during guard selection, leading to weaker anonymity and worse + performance. Fixes bug 17772; bugfix on 0.2.4.8-alpha. Discovered + by Mohsen Imani. + + o Major bugfixes (key management, backport from 0.2.8.3-alpha): + - 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 (parsing, backported from 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 (security, memory erasure, backport from 0.2.8.1-alpha): + - Make memwipe() do nothing when passed a NULL pointer or buffer of + zero size. Check size argument to memwipe() for underflow. Fixes + bug 18089; bugfix on 0.2.3.25 and 0.2.4.6-alpha. Reported by "gk", + patch by "teor". + + o Minor features (bug-resistance, backport from 0.2.8.2-alpha): + - Make Tor survive errors involving connections without a + corresponding event object. Previously we'd fail with an + assertion; now we produce a log message. Related to bug 16248. + + o Minor features (geoip): + - Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (compilation, backport from 0.2.7.6): + - Fix a compilation warning with Clang 3.6: Do not check the + presence of an address which can never be NULL. Fixes bug 17781. + + +Changes in version 0.2.6.10 - 2015-07-12 + Tor version 0.2.6.10 fixes some significant stability and hidden + service client bugs, bulletproofs the cryptography init process, and + fixes a bug when using the sandbox code with some older versions of + Linux. Everyone running an older version, especially an older version + of 0.2.6, should upgrade. + + o Major bugfixes (hidden service clients, stability): + - Stop refusing to store updated hidden service descriptors on a + client. This reverts commit 9407040c59218 (which indeed fixed bug + 14219, but introduced a major hidden service reachability + regression detailed in bug 16381). This is a temporary fix since + we can live with the minor issue in bug 14219 (it just results in + some load on the network) but the regression of 16381 is too much + of a setback. First-round fix for bug 16381; bugfix + on 0.2.6.3-alpha. + + o Major bugfixes (stability): + - Stop crashing with an assertion failure when parsing certain kinds + of malformed or truncated microdescriptors. Fixes bug 16400; + bugfix on 0.2.6.1-alpha. Found by "torkeln"; fix based on a patch + by "cypherpunks_backup". + - Stop random client-side assertion failures that could occur when + connecting to a busy hidden service, or connecting to a hidden + service while a NEWNYM is in progress. Fixes bug 16013; bugfix + on 0.1.0.1-rc. + + o Minor features (geoip): + - Update geoip to the June 3 2015 Maxmind GeoLite2 Country database. + - Update geoip6 to the June 3 2015 Maxmind GeoLite2 Country database. + + o Minor bugfixes (crypto error-handling): + - Check for failures from crypto_early_init, and refuse to continue. + A previous typo meant that we could keep going with an + uninitialized crypto library, and would have OpenSSL initialize + its own PRNG. Fixes bug 16360; bugfix on 0.2.5.2-alpha, introduced + when implementing ticket 4900. Patch by "teor". + + o Minor bugfixes (Linux seccomp2 sandbox): + - Allow pipe() and pipe2() syscalls in the seccomp2 sandbox: we need + these when eventfd2() support is missing. Fixes bug 16363; bugfix + on 0.2.6.3-alpha. Patch from "teor". + + +Changes in version 0.2.6.9 - 2015-06-11 + Tor 0.2.6.9 fixes a regression in the circuit isolation code, increases the + requirements for receiving an HSDir flag, and addresses some other small + bugs in the systemd and sandbox code. Clients using circuit isolation + should upgrade; all directory authorities should upgrade. + + o Major bugfixes (client-side privacy): + - Properly separate out each SOCKSPort when applying stream + isolation. The error occurred because each port's session group was + being overwritten by a default value when the listener connection + was initialized. Fixes bug 16247; bugfix on 0.2.6.3-alpha. Patch + by "jojelino". + + o Minor feature (directory authorities, security): + - The HSDir flag given by authorities now requires the Stable flag. + For the current network, this results in going from 2887 to 2806 + HSDirs. Also, it makes it harder for an attacker to launch a sybil + attack by raising the effort for a relay to become Stable which + takes at the very least 7 days to do so and by keeping the 96 + hours uptime requirement for HSDir. Implements ticket 8243. + + o Minor bugfixes (compilation): + - Build with --enable-systemd correctly when libsystemd is + installed, but systemd is not. Fixes bug 16164; bugfix on + 0.2.6.3-alpha. Patch from Peter Palfrader. + + o Minor bugfixes (Linux seccomp2 sandbox): + - Fix sandboxing to work when running as a relaymby renaming of + secret_id_key, and allowing the eventfd2 and futex syscalls. Fixes + bug 16244; bugfix on 0.2.6.1-alpha. Patch by Peter Palfrader. + - Allow systemd connections to work with the Linux seccomp2 sandbox + code. Fixes bug 16212; bugfix on 0.2.6.2-alpha. Patch by + Peter Palfrader. + + o Minor bugfixes (tests): + - Fix a crash in the unit tests when built with MSVC2013. Fixes bug + 16030; bugfix on 0.2.6.2-alpha. Patch from "NewEraCracker". + + +Changes in version 0.2.6.8 - 2015-05-21 + Tor 0.2.6.8 fixes a bit of dodgy code in parsing INTRODUCE2 cells, and + fixes an authority-side bug in assigning the HSDir flag. All directory + authorities should upgrade. + + o Major bugfixes (hidden services, backport from 0.2.7.1-alpha): + - Revert commit that made directory authorities assign the HSDir + flag to relay without a DirPort; this was bad because such relays + can't handle BEGIN_DIR cells. Fixes bug 15850; bugfix + on tor-0.2.6.3-alpha. + + o Minor bugfixes (hidden service, backport from 0.2.7.1-alpha): + - Fix an out-of-bounds read when parsing invalid INTRODUCE2 cells on + a client authorized hidden service. Fixes bug 15823; bugfix + on 0.2.1.6-alpha. + + o Minor features (geoip): + - Update geoip to the April 8 2015 Maxmind GeoLite2 Country database. + - Update geoip6 to the April 8 2015 Maxmind GeoLite2 + Country database. + +Changes in version 0.2.6.7 - 2015-04-06 + Tor 0.2.6.7 fixes two security issues that could be used by an + attacker to crash hidden services, or crash clients visiting hidden + services. Hidden services should upgrade as soon as possible; clients + should upgrade whenever packages become available. + + This release also contains two simple improvements to make hidden + services a bit less vulnerable to denial-of-service attacks. + + o Major bugfixes (security, hidden service): + - Fix an issue that would allow a malicious client to trigger an + assertion failure and halt a hidden service. Fixes bug 15600; + bugfix on 0.2.1.6-alpha. Reported by "disgleirio". + - Fix a bug that could cause a client to crash with an assertion + failure when parsing a malformed hidden service descriptor. Fixes + bug 15601; bugfix on 0.2.1.5-alpha. Found by "DonnchaC". + + o Minor features (DoS-resistance, hidden service): + - Introduction points no longer allow multiple INTRODUCE1 cells to + arrive on the same circuit. This should make it more expensive for + attackers to overwhelm hidden services with introductions. + Resolves ticket 15515. + - Decrease the amount of reattempts that a hidden service performs + when its rendezvous circuits fail. This reduces the computational + cost for running a hidden service under heavy load. Resolves + ticket 11447. + + +Changes in version 0.2.6.6 - 2015-03-24 + Tor 0.2.6.6 is the first stable release in the 0.2.6 series. + + It adds numerous safety, security, correctness, and performance + improvements. Client programs can be configured to use more kinds of + sockets, AutomapHosts works better, the multithreading backend is + improved, cell transmission is refactored, test coverage is much + higher, more denial-of-service attacks are handled, guard selection is + improved to handle long-term guards better, pluggable transports + should work a bit better, and some annoying hidden service performance + bugs should be addressed. + + o Minor bugfixes (portability): + - Use the correct datatype in the SipHash-2-4 function to prevent + compilers from assuming any sort of alignment. Fixes bug 15436; + bugfix on 0.2.5.3-alpha. + + +Changes in version 0.2.6.5-rc - 2015-03-18 + Tor 0.2.6.5-rc is the second and (hopefully) last release candidate in + the 0.2.6. It fixes a small number of bugs found in 0.2.6.4-rc. + + o Major bugfixes (client): + - Avoid crashing when making certain configuration option changes on + clients. Fixes bug 15245; bugfix on 0.2.6.3-alpha. Reported + by "anonym". + + o Major bugfixes (pluggable transports): + - Initialize the extended OR Port authentication cookie before + launching pluggable transports. This prevents a race condition + that occured when server-side pluggable transports would cache the + authentication cookie before it has been (re)generated. Fixes bug + 15240; bugfix on 0.2.5.1-alpha. + + o Major bugfixes (portability): + - Do not crash on startup when running on Solaris. Fixes a bug + related to our fix for 9495; bugfix on 0.2.6.1-alpha. Reported + by "ruebezahl". + + o Minor features (heartbeat): + - On relays, report how many connections we negotiated using each + version of the Tor link protocols. This information will let us + know if removing support for very old versions of the Tor + protocols is harming the network. Closes ticket 15212. + + o Code simplification and refactoring: + - Refactor main loop to extract the 'loop' part. This makes it + easier to run Tor under Shadow. Closes ticket 15176. + + +Changes in version 0.2.5.11 - 2015-03-17 + Tor 0.2.5.11 is the second stable release in the 0.2.5 series. + + It backports several bugfixes from the 0.2.6 branch, including a + couple of medium-level security fixes for relays and exit nodes. + It also updates the list of directory authorities. + + o Directory authority changes: + - Remove turtles as a directory authority. + - Add longclaw as a new (v3) directory authority. This implements + ticket 13296. This keeps the directory authority count at 9. + - The directory authority Faravahar has a new IP address. This + closes ticket 14487. + + o Major bugfixes (crash, OSX, security): + - Fix a remote denial-of-service opportunity caused by a bug in + OSX's _strlcat_chk() function. Fixes bug 15205; bug first appeared + in OSX 10.9. + + o Major bugfixes (relay, stability, possible security): + - Fix a bug that could lead to a relay crashing with an assertion + failure if a buffer of exactly the wrong layout was passed to + buf_pullup() at exactly the wrong time. Fixes bug 15083; bugfix on + 0.2.0.10-alpha. Patch from 'cypherpunks'. + - Do not assert if the 'data' pointer on a buffer is advanced to the + very end of the buffer; log a BUG message instead. Only assert if + it is past that point. Fixes bug 15083; bugfix on 0.2.0.10-alpha. + + o Major bugfixes (exit node stability): + - Fix an assertion failure that could occur under high DNS load. + Fixes bug 14129; bugfix on Tor 0.0.7rc1. Found by "jowr"; + diagnosed and fixed by "cypherpunks". + + o Major bugfixes (Linux seccomp2 sandbox): + - Upon receiving sighup with the seccomp2 sandbox enabled, do not + crash during attempts to call wait4. Fixes bug 15088; bugfix on + 0.2.5.1-alpha. Patch from "sanic". + + o Minor features (controller): + - New "GETINFO bw-event-cache" to get information about recent + bandwidth events. Closes ticket 14128. Useful for controllers to + get recent bandwidth history after the fix for ticket 13988. + + o Minor features (geoip): + - Update geoip to the March 3 2015 Maxmind GeoLite2 Country database. + - Update geoip6 to the March 3 2015 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (client, automapping): + - Avoid crashing on torrc lines for VirtualAddrNetworkIPv[4|6] when + no value follows the option. Fixes bug 14142; bugfix on + 0.2.4.7-alpha. Patch by "teor". + - Fix a memory leak when using AutomapHostsOnResolve. Fixes bug + 14195; bugfix on 0.1.0.1-rc. + + o Minor bugfixes (compilation): + - Build without warnings with the stock OpenSSL srtp.h header, which + has a duplicate declaration of SSL_get_selected_srtp_profile(). + Fixes bug 14220; this is OpenSSL's bug, not ours. + + o Minor bugfixes (directory authority): + - Allow directory authorities to fetch more data from one another if + they find themselves missing lots of votes. Previously, they had + been bumping against the 10 MB queued data limit. Fixes bug 14261; + bugfix on 0.1.2.5-alpha. + - Enlarge the buffer to read bwauth generated files to avoid an + issue when parsing the file in dirserv_read_measured_bandwidths(). + Fixes bug 14125; bugfix on 0.2.2.1-alpha. + + o Minor bugfixes (statistics): + - Increase period over which bandwidth observations are aggregated + from 15 minutes to 4 hours. Fixes bug 13988; bugfix on 0.0.8pre1. + + o Minor bugfixes (preventative security, C safety): + - When reading a hexadecimal, base-32, or base-64 encoded value from + a string, always overwrite the whole output buffer. This prevents + some bugs where we would look at (but fortunately, not reveal) + uninitialized memory on the stack. Fixes bug 14013; bugfix on all + versions of Tor. + + +Changes in version 0.2.4.26 - 2015-03-17 + Tor 0.2.4.26 includes an updated list of directory authorities. It + also backports a couple of stability and security bugfixes from 0.2.5 + and beyond. + o Directory authority changes: + - Remove turtles as a directory authority. + - Add longclaw as a new (v3) directory authority. This implements + ticket 13296. This keeps the directory authority count at 9. + - The directory authority Faravahar has a new IP address. This + closes ticket 14487. + + o Major bugfixes (exit node stability, also in 0.2.6.3-alpha): + - Fix an assertion failure that could occur under high DNS load. + Fixes bug 14129; bugfix on Tor 0.0.7rc1. Found by "jowr"; + diagnosed and fixed by "cypherpunks". + + o Major bugfixes (relay, stability, possible security, also in 0.2.6.4-rc): + - Fix a bug that could lead to a relay crashing with an assertion + failure if a buffer of exactly the wrong layout was passed to + buf_pullup() at exactly the wrong time. Fixes bug 15083; bugfix on + 0.2.0.10-alpha. Patch from 'cypherpunks'. + - Do not assert if the 'data' pointer on a buffer is advanced to the + very end of the buffer; log a BUG message instead.

It also resolves some minor issues left over from, or + introduced in, Tor 0.2.6.3-alpha or earlier. + + o Major bugfixes (crash, OSX, security): + - Fix a remote denial-of-service opportunity caused by a bug in + OSX's _strlcat_chk() function. Fixes bug 15205; bug first appeared + in OSX 10.9. + + o Major bugfixes (relay, stability, possible security): + - Fix a bug that could lead to a relay crashing with an assertion + failure if a buffer of exactly the wrong layout is passed to + buf_pullup() at exactly the wrong time.

Only assert if + it is past that point. Fixes bug 15083; bugfix on 0.2.0.10-alpha. + + o Major bugfixes (FreeBSD IPFW transparent proxy): + - Fix address detection with FreeBSD transparent proxies, when + "TransProxyType ipfw" is in use. Fixes bug 15064; bugfix + on 0.2.5.4-alpha. + + o Major bugfixes (Linux seccomp2 sandbox): + - Pass IPPROTO_TCP rather than 0 to socket(), so that the Linux + seccomp2 sandbox doesn't fail. Fixes bug 14989; bugfix + on 0.2.6.3-alpha. + - Allow AF_UNIX hidden services to be used with the seccomp2 + sandbox. Fixes bug 15003; bugfix on 0.2.6.3-alpha. + - Upon receiving sighup with the seccomp2 sandbox enabled, do not + crash during attempts to call wait4. Fixes bug 15088; bugfix on + 0.2.5.1-alpha.

Closes + ticket 14950. + + o Minor bugfixes (certificate handling): + - If an authority operator accidentally makes a signing certificate + with a future publication time, do not discard its real signing + certificates. Fixes bug 11457; bugfix on 0.2.0.3-alpha. + - Remove any old authority certificates that have been superseded + for at least two days. Previously, we would keep superseded + certificates until they expired, if they were published close in + time to the certificate that superseded them. Fixes bug 11454; + bugfix on 0.2.1.8-alpha. + + o Minor bugfixes (compilation): + - Fix a compilation warning on s390.

Closes ticket 19271. + + o Directory authority changes (backport from 0.2.9.2-alpha): + - The "Tonga" bridge authority has been retired; the new bridge + authority is "Bifroest". Closes tickets 19728 and 19690. + + o Directory authority key updates (backport from 0.2.8.1-alpha): + - Update the V3 identity key for the dannenberg directory authority: + it was changed on 18 November 2015. Closes task 17906. Patch + by "teor". + + o Major features (security fixes, backport from 0.2.9.4-alpha): + - Prevent a class of security bugs caused by treating the contents + of a buffer chunk as if they were a NUL-terminated string. At + least one such bug seems to be present in all currently used + versions of Tor, and would allow an attacker to remotely crash + most Tor instances, especially those compiled with extra compiler + hardening. With this defense in place, such bugs can't crash Tor, + though we should still fix them as they occur. Closes ticket + 20384 (TROVE-2016-10-001). + + o Major bugfixes (parsing, security, backport from 0.2.9.8): + - Fix a bug in parsing that could cause clients to read a single + byte past the end of an allocated region. This bug could be used + to cause hardened clients (built with --enable-expensive-hardening) + to crash if they tried to visit a hostile hidden service. Non- + hardened clients are only affected depending on the details of + their platform's memory allocator. Fixes bug 21018; bugfix on + 0.2.0.8-alpha. Found by using libFuzzer. Also tracked as TROVE- + 2016-12-002 and as CVE-2016-1254. + + o Major bugfixes (security, client, DNS proxy, backport from 0.2.8.3-alpha): + - 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, correctness, backport from 0.2.7.4-rc): + - Fix an error that could cause us to read 4 bytes before the + beginning of an openssl string. This bug could be used to cause + Tor to crash on systems with unusual malloc implementations, or + systems with unusual hardening installed. Fixes bug 17404; bugfix + on 0.2.3.6-alpha. + + o Major bugfixes (security, pointers, backport from 0.2.8.2-alpha): + - Avoid a difficult-to-trigger heap corruption attack when extending + a smartlist to contain over 16GB of pointers. Fixes bug 18162; + bugfix on 0.1.1.11-alpha, which fixed a related bug incompletely. + Reported by Guido Vranken. + + o Major bugfixes (dns proxy mode, crash, backport from 0.2.8.2-alpha): + - Avoid crashing when running as a DNS proxy. Fixes bug 16248; + bugfix on 0.2.0.1-alpha. Patch from "cypherpunks". + + o Major bugfixes (guard selection, backport from 0.2.7.6): + - Actually look at the Guard flag when selecting a new directory + guard. When we implemented the directory guard design, we + accidentally started treating all relays as if they have the Guard + flag during guard selection, leading to weaker anonymity and worse + performance. Fixes bug 17772; bugfix on 0.2.4.8-alpha. Discovered + by Mohsen Imani. + + o Major bugfixes (key management, backport from 0.2.8.3-alpha): + - 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 (parsing, backported from 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 (security, memory erasure, backport from 0.2.8.1-alpha): + - Make memwipe() do nothing when passed a NULL pointer or buffer of + zero size. Check size argument to memwipe() for underflow. Fixes + bug 18089; bugfix on 0.2.3.25 and 0.2.4.6-alpha. Reported by "gk", + patch by "teor". + + o Minor features (bug-resistance, backport from 0.2.8.2-alpha): + - Make Tor survive errors involving connections without a + corresponding event object. Previously we'd fail with an + assertion; now we produce a log message. Related to bug 16248. + + o Minor features (geoip): + - Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (compilation, backport from 0.2.7.6): + - Fix a compilation warning with Clang 3.6: Do not check the + presence of an address which can never be NULL. Fixes bug 17781. + + +Changes in version 0.2.6.10 - 2015-07-12 + Tor version 0.2.6.10 fixes some significant stability and hidden + service client bugs, bulletproofs the cryptography init process, and + fixes a bug when using the sandbox code with some older versions of + Linux. Everyone running an older version, especially an older version + of 0.2.6, should upgrade. + + o Major bugfixes (hidden service clients, stability): + - Stop refusing to store updated hidden service descriptors on a + client. This reverts commit 9407040c59218 (which indeed fixed bug + 14219, but introduced a major hidden service reachability + regression detailed in bug 16381). This is a temporary fix since + we can live with the minor issue in bug 14219 (it just results in + some load on the network) but the regression of 16381 is too much + of a setback. First-round fix for bug 16381; bugfix + on 0.2.6.3-alpha. + + o Major bugfixes (stability): + - Stop crashing with an assertion failure when parsing certain kinds + of malformed or truncated microdescriptors. Fixes bug 16400; + bugfix on 0.2.6.1-alpha. Found by "torkeln"; fix based on a patch + by "cypherpunks_backup". + - Stop random client-side assertion failures that could occur when + connecting to a busy hidden service, or connecting to a hidden + service while a NEWNYM is in progress. Fixes bug 16013; bugfix + on 0.1.0.1-rc. + + o Minor features (geoip): + - Update geoip to the June 3 2015 Maxmind GeoLite2 Country database. + - Update geoip6 to the June 3 2015 Maxmind GeoLite2 Country database. + + o Minor bugfixes (crypto error-handling): + - Check for failures from crypto_early_init, and refuse to continue. + A previous typo meant that we could keep going with an + uninitialized crypto library, and would have OpenSSL initialize + its own PRNG. Fixes bug 16360; bugfix on 0.2.5.2-alpha, introduced + when implementing ticket 4900. Patch by "teor". + + o Minor bugfixes (Linux seccomp2 sandbox): + - Allow pipe() and pipe2() syscalls in the seccomp2 sandbox: we need + these when eventfd2() support is missing. Fixes bug 16363; bugfix + on 0.2.6.3-alpha. Patch from "teor". + + +Changes in version 0.2.6.9 - 2015-06-11 + Tor 0.2.6.9 fixes a regression in the circuit isolation code, increases the + requirements for receiving an HSDir flag, and addresses some other small + bugs in the systemd and sandbox code. Clients using circuit isolation + should upgrade; all directory authorities should upgrade. + + o Major bugfixes (client-side privacy): + - Properly separate out each SOCKSPort when applying stream + isolation. The error occurred because each port's session group was + being overwritten by a default value when the listener connection + was initialized. Fixes bug 16247; bugfix on 0.2.6.3-alpha. Patch + by "jojelino". + + o Minor feature (directory authorities, security): + - The HSDir flag given by authorities now requires the Stable flag. + For the current network, this results in going from 2887 to 2806 + HSDirs. Also, it makes it harder for an attacker to launch a sybil + attack by raising the effort for a relay to become Stable which + takes at the very least 7 days to do so and by keeping the 96 + hours uptime requirement for HSDir. Implements ticket 8243. + + o Minor bugfixes (compilation): + - Build with --enable-systemd correctly when libsystemd is + installed, but systemd is not. Fixes bug 16164; bugfix on + 0.2.6.3-alpha. Patch from Peter Palfrader. + + o Minor bugfixes (Linux seccomp2 sandbox): + - Fix sandboxing to work when running as a relaymby renaming of + secret_id_key, and allowing the eventfd2 and futex syscalls. Fixes + bug 16244; bugfix on 0.2.6.1-alpha. Patch by Peter Palfrader. + - Allow systemd connections to work with the Linux seccomp2 sandbox + code. Fixes bug 16212; bugfix on 0.2.6.2-alpha. Patch by + Peter Palfrader. + + o Minor bugfixes (tests): + - Fix a crash in the unit tests when built with MSVC2013. Fixes bug + 16030; bugfix on 0.2.6.2-alpha. Patch from "NewEraCracker". + + +Changes in version 0.2.6.8 - 2015-05-21 + Tor 0.2.6.8 fixes a bit of dodgy code in parsing INTRODUCE2 cells, and + fixes an authority-side bug in assigning the HSDir flag. All directory + authorities should upgrade. + + o Major bugfixes (hidden services, backport from 0.2.7.1-alpha): + - Revert commit that made directory authorities assign the HSDir + flag to relay without a DirPort; this was bad because such relays + can't handle BEGIN_DIR cells. Fixes bug 15850; bugfix + on tor-0.2.6.3-alpha. + + o Minor bugfixes (hidden service, backport from 0.2.7.1-alpha): + - Fix an out-of-bounds read when parsing invalid INTRODUCE2 cells on + a client authorized hidden service. Fixes bug 15823; bugfix + on 0.2.1.6-alpha. + + o Minor features (geoip): + - Update geoip to the April 8 2015 Maxmind GeoLite2 Country database. + - Update geoip6 to the April 8 2015 Maxmind GeoLite2 + Country database. + + +Changes in version 0.2.6.7 - 2015-04-06 + Tor 0.2.6.7 fixes two security issues that could be used by an + attacker to crash hidden services, or crash clients visiting hidden + services. Hidden services should upgrade as soon as possible; clients + should upgrade whenever packages become available. + + This release also contains two simple improvements to make hidden + services a bit less vulnerable to denial-of-service attacks. + + o Major bugfixes (security, hidden service): + - Fix an issue that would allow a malicious client to trigger an + assertion failure and halt a hidden service. Fixes bug 15600; + bugfix on 0.2.1.6-alpha. Reported by "disgleirio". + - Fix a bug that could cause a client to crash with an assertion + failure when parsing a malformed hidden service descriptor. Fixes + bug 15601; bugfix on 0.2.1.5-alpha. Found by "DonnchaC". + + o Minor features (DoS-resistance, hidden service): + - Introduction points no longer allow multiple INTRODUCE1 cells to + arrive on the same circuit. This should make it more expensive for + attackers to overwhelm hidden services with introductions. + Resolves ticket 15515. + - Decrease the amount of reattempts that a hidden service performs + when its rendezvous circuits fail. This reduces the computational + cost for running a hidden service under heavy load. Resolves + ticket 11447. + + +Changes in version 0.2.6.6 - 2015-03-24 + Tor 0.2.6.6 is the first stable release in the 0.2.6 series. + + It adds numerous safety, security, correctness, and performance + improvements. Client programs can be configured to use more kinds of + sockets, AutomapHosts works better, the multithreading backend is + improved, cell transmission is refactored, test coverage is much + higher, more denial-of-service attacks are handled, guard selection is + improved to handle long-term guards better, pluggable transports + should work a bit better, and some annoying hidden service performance + bugs should be addressed. + + o New compiler and system requirements: + - Tor 0.2.6.x requires that your compiler support more of the C99 + language standard than before. The 'configure' script now detects + whether your compiler supports C99 mid-block declarations and + designated initializers. If it does not, Tor will not compile. + + We may revisit this requirement if it turns out that a significant + number of people need to build Tor with compilers that don't + bother implementing a 15-year-old standard. Closes ticket 13233. + - Tor no longer supports systems without threading support. When we + began working on Tor, there were several systems that didn't have + threads, or where the thread support wasn't able to run the + threads of a single process on multiple CPUs. That no longer + holds: every system where Tor needs to run well now has threading + support. Resolves ticket 12439. + + o Deprecated versions and removed support: + - Tor relays older than 0.2.4.18-rc are no longer allowed to + advertise themselves on the network. Closes ticket 13555. + - Tor clients no longer support connecting to hidden services + running on Tor 0.2.2.x and earlier; the Support022HiddenServices + option has been removed. (There shouldn't be any hidden services + running these versions on the network.) Closes ticket 7803. + + o Directory authority changes: + - The directory authority Faravahar has a new IP address. This + closes ticket 14487. + - Remove turtles as a directory authority. + - Add longclaw as a new (v3) directory authority. This implements + ticket 13296. This keeps the directory authority count at 9. + + o Major features (bridges): + - Expose the outgoing upstream HTTP/SOCKS proxy to pluggable + transports if they are configured via the "TOR_PT_PROXY" + environment variable. Implements proposal 232. Resolves + ticket 8402. + + o Major features (changed defaults): + - Prevent relay operators from unintentionally running exits: When a + relay is configured as an exit node, we now warn the user unless + the "ExitRelay" option is set to 1. We warn even more loudly if + the relay is configured with the default exit policy, since this + can indicate accidental misconfiguration. Setting "ExitRelay 0" + stops Tor from running as an exit relay. Closes ticket 10067. + + o Major features (client performance, hidden services): + - Allow clients to use optimistic data when connecting to a hidden + service, which should remove a round-trip from hidden service + initialization. See proposal 181 for details. Implements + ticket 13211. + + o Major features (directory system): + - Upon receiving an unparseable directory object, if its digest + matches what we expected, then don't try to download it again. + Previously, when we got a descriptor we didn't like, we would keep + trying to download it over and over. Closes ticket 11243. + - When downloading server- or microdescriptors from a directory + server, we no longer launch multiple simultaneous requests to the + same server. This reduces load on the directory servers, + especially when directory guards are in use. Closes ticket 9969. + - When downloading server- or microdescriptors over a tunneled + connection, do not limit the length of our requests to what the + Squid proxy is willing to handle. Part of ticket 9969. + - Authorities can now vote on the correct digests and latest + versions for different software packages. This allows packages + that include Tor to use the Tor authority system as a way to get + notified of updates and their correct digests. Implements proposal + 227. Closes ticket 10395. + + o Major features (guards): + - Introduce the Guardfraction feature to improves load balancing on + guard nodes. Specifically, it aims to reduce the traffic gap that + guard nodes experience when they first get the Guard flag. This is + a required step if we want to increase the guard lifetime to 9 + months or greater. Closes ticket 9321. + + o Major features (hidden services): + - Make HS port scanning more difficult by immediately closing the + circuit when a user attempts to connect to a nonexistent port. + Closes ticket 13667. + - Add a HiddenServiceStatistics option that allows Tor relays to + gather and publish statistics about the overall size and volume of + hidden service usage. Specifically, when this option is turned on, + an HSDir will publish an approximate number of hidden services + that have published descriptors to it the past 24 hours. Also, if + a relay has acted as a hidden service rendezvous point, it will + publish the approximate amount of rendezvous cells it has relayed + the past 24 hours. The statistics themselves are obfuscated so + that the exact values cannot be derived. For more details see + proposal 238, "Better hidden service stats from Tor relays". This + feature is currently disabled by default. Implements feature 13192. + + o Major features (performance): + - Make the CPU worker implementation more efficient by avoiding the + kernel and lengthening pipelines. The original implementation used + sockets to transfer data from the main thread to the workers, and + didn't allow any thread to be assigned more than a single piece of + work at once. The new implementation avoids communications + overhead by making requests in shared memory, avoiding kernel IO + where possible, and keeping more requests in flight at once. + Implements ticket 9682. + + o Major features (relay): + - Raise the minimum acceptable configured bandwidth rate for bridges + to 50 KiB/sec and for relays to 75 KiB/sec. (The old values were + 20 KiB/sec.) Closes ticket 13822. + - Complete revision of the code that relays use to decide which cell + to send next. Formerly, we selected the best circuit to write on + each channel, but we didn't select among channels in any + sophisticated way. Now, we choose the best circuits globally from + among those whose channels are ready to deliver traffic. + + This patch implements a new inter-cmux comparison API, a global + high/low watermark mechanism and a global scheduler loop for + transmission prioritization across all channels as well as among + circuits on one channel. This schedule is currently tuned to + (tolerantly) avoid making changes in network performance, but it + should form the basis for major circuit performance increases in + the future. Code by Andrea; tuning by Rob Jansen; implements + ticket 9262. + + o Major features (sample torrc): + - Add a new, infrequently-changed "torrc.minimal". This file is + similar to torrc.sample, but it will change as infrequently as + possible, for the benefit of users whose systems prompt them for + intervention whenever a default configuration file is changed. + Making this change allows us to update torrc.sample to be a more + generally useful "sample torrc". + + o Major features (security, unix domain sockets): + - Allow SocksPort to be an AF_UNIX Unix Domain Socket. Now high risk + applications can reach Tor without having to create AF_INET or + AF_INET6 sockets, meaning they can completely disable their + ability to make non-Tor network connections. To create a socket of + this type, use "SocksPort unix:/path/to/socket". Implements + ticket 12585. + - Support mapping hidden service virtual ports to AF_UNIX sockets. + The syntax is "HiddenServicePort 80 unix:/path/to/socket". + Implements ticket 11485. + + o Major bugfixes (client, automap): + - Repair automapping with IPv6 addresses. This automapping should + have worked previously, but one piece of debugging code that we + inserted to detect a regression actually caused the regression to + manifest itself again. Fixes bug 13811 and bug 12831; bugfix on + 0.2.4.7-alpha. Diagnosed and fixed by Francisco Blas + Izquierdo Riera. + + o Major bugfixes (crash, OSX, security): + - Fix a remote denial-of-service opportunity caused by a bug in + OSX's _strlcat_chk() function. Fixes bug 15205; bug first appeared + in OSX 10.9. + + o Major bugfixes (directory authorities): + - Do not assign the HSDir flag to relays if they are not Valid, or + currently hibernating. Fixes 12573; bugfix on 0.2.0.10-alpha. + + o Major bugfixes (directory bandwidth performance): + - Don't flush the zlib buffer aggressively when compressing + directory information for clients. This should save about 7% of + the bandwidth currently used for compressed descriptors and + microdescriptors. Fixes bug 11787; bugfix on 0.1.1.23. + + o Major bugfixes (exit node stability): + - Fix an assertion failure that could occur under high DNS load. + Fixes bug 14129; bugfix on Tor 0.0.7rc1. Found by "jowr"; + diagnosed and fixed by "cypherpunks". + + o Major bugfixes (FreeBSD IPFW transparent proxy): + - Fix address detection with FreeBSD transparent proxies, when + "TransProxyType ipfw" is in use. Fixes bug 15064; bugfix + on 0.2.5.4-alpha. + + o Major bugfixes (hidden services): + - When closing an introduction circuit that was opened in parallel + with others, don't mark the introduction point as unreachable. + Previously, the first successful connection to an introduction + point would make the other introduction points get marked as + having timed out. Fixes bug 13698; bugfix on 0.0.6rc2. + + o Major bugfixes (Linux seccomp2 sandbox): + - Upon receiving sighup with the seccomp2 sandbox enabled, do not + crash during attempts to call wait4. Fixes bug 15088; bugfix on + 0.2.5.1-alpha. Patch from "sanic". + + o Major bugfixes (mixed relay-client operation): + - When running as a relay and client at the same time (not + recommended), if we decide not to use a new guard because we want + to retry older guards, only close the locally-originating circuits + passing through that guard. Previously we would close all the + circuits through that guard. Fixes bug 9819; bugfix on + 0.2.1.1-alpha. Reported by "skruffy". + + o Major bugfixes (pluggable transports): + - Initialize the extended OR Port authentication cookie before + launching pluggable transports. This prevents a race condition + that occured when server-side pluggable transports would cache the + authentication cookie before it has been (re)generated. Fixes bug + 15240; bugfix on 0.2.5.1-alpha. + + o Major bugfixes (relay, stability, possible security): + - Fix a bug that could lead to a relay crashing with an assertion + failure if a buffer of exactly the wrong layout is passed to + buf_pullup() at exactly the wrong time. Fixes bug 15083; bugfix on + 0.2.0.10-alpha. Patch from "cypherpunks". + - Do not assert if the 'data' pointer on a buffer is advanced to the + very end of the buffer; log a BUG message instead. Only assert if + it is past that point. Fixes bug 15083; bugfix on 0.2.0.10-alpha. + + o Minor features (build): + - New --disable-system-torrc compile-time option to prevent Tor from + looking for the system-wide torrc or torrc-defaults files. + Resolves ticket 13037. + + o Minor features (client): + - Clients are now willing to send optimistic data (before they + receive a 'connected' cell) to relays of any version. (Relays + without support for optimistic data are no longer supported on the + Tor network.) Resolves ticket 13153. + + o Minor features (client): + - Validate hostnames in SOCKS5 requests more strictly. If SafeSocks + is enabled, reject requests with IP addresses as hostnames. + Resolves ticket 13315. + + o Minor features (controller): + - Add a "SIGNAL HEARTBEAT" controller command that tells Tor to + write an unscheduled heartbeat message to the log. Implements + feature 9503. + - Include SOCKS_USERNAME and SOCKS_PASSWORD values in controller + events so controllers can observe circuit isolation inputs. Closes + ticket 8405. + - ControlPort now supports the unix:/path/to/socket syntax as an + alternative to the ControlSocket option, for consistency with + SocksPort and HiddenServicePort. Closes ticket 14451. + - New "GETINFO bw-event-cache" to get information about recent + bandwidth events. Closes ticket 14128. Useful for controllers to + get recent bandwidth history after the fix for ticket 13988. + - Messages about problems in the bootstrap process now include + information about the server we were trying to connect to when we + noticed the problem. Closes ticket 15006. + + o Minor features (Denial of service resistance): + - Count the total number of bytes used storing hidden service + descriptors against the value of MaxMemInQueues. If we're low on + memory, and more than 20% of our memory is used holding hidden + service descriptors, free them until no more than 10% of our + memory holds hidden service descriptors. Free the least recently + fetched descriptors first. Resolves ticket 13806. + - When we have recently been under memory pressure (over 3/4 of + MaxMemInQueues is allocated), then allocate smaller zlib objects + for small requests. Closes ticket 11791. + + o Minor features (directory authorities): + - Don't list relays with a bandwidth estimate of 0 in the consensus. + Implements a feature proposed during discussion of bug 13000. + - In tor-gencert, report an error if the user provides the same + argument more than once. + - If a directory authority can't find a best consensus method in the + votes that it holds, it now falls back to its favorite consensus + method. Previously, it fell back to method 1. Neither of these is + likely to get enough signatures, but "fall back to favorite" + doesn't require us to maintain support an obsolete consensus + method. Implements part of proposal 215. + + o Minor features (geoip): + - Update geoip to the March 3 2015 Maxmind GeoLite2 Country database. + - Update geoip6 to the March 3 2015 Maxmind GeoLite2 + Country database. + + o Minor features (guard nodes): + - Reduce the time delay before saving guard status to disk from 10 + minutes to 30 seconds (or from one hour to 10 minutes if + AvoidDiskWrites is set). Closes ticket 12485. + + o Minor features (heartbeat): + - On relays, report how many connections we negotiated using each + version of the Tor link protocols. This information will let us + know if removing support for very old versions of the Tor + protocols is harming the network. Closes ticket 15212. + + o Minor features (hidden service): + - Make Sybil attacks against hidden services harder by changing the + minimum time required to get the HSDir flag from 25 hours up to 96 + hours. Addresses ticket 14149. + - New option "HiddenServiceAllowUnknownPorts" to allow hidden + services to disable the anti-scanning feature introduced in + 0.2.6.2-alpha. With this option not set, a connection to an + unlisted port closes the circuit. With this option set, only a + RELAY_DONE cell is sent. Closes ticket 14084. + - When re-enabling the network, don't try to build introduction + circuits until we have successfully built a circuit. This makes + hidden services come up faster when the network is re-enabled. + Patch from "akwizgran". Closes ticket 13447. + - When we fail to retrieve a hidden service descriptor, send the + controller an "HS_DESC FAILED" controller event. Implements + feature 13212. + - New HiddenServiceDirGroupReadable option to cause hidden service + directories and hostname files to be created group-readable. Patch + from "anon", David Stainton, and "meejah". Closes ticket 11291. + + o Minor features (interface): + - Implement "-f -" command-line option to read torrc configuration + from standard input, if you don't want to store the torrc file in + the file system. Implements feature 13865. + + o Minor features (logging): + - Add a count of unique clients to the bridge heartbeat message. + Resolves ticket 6852. + - Suppress "router info incompatible with extra info" message when + reading extrainfo documents from cache. (This message got loud + around when we closed bug 9812 in 0.2.6.2-alpha.) Closes + ticket 13762. + - Elevate hidden service authorized-client message from DEBUG to + INFO. Closes ticket 14015. + - On Unix-like systems, you can now use named pipes as the target of + the Log option, and other options that try to append to files. + Closes ticket 12061. Patch from "carlo von lynX". + - When opening a log file at startup, send it every log message that + we generated between startup and opening it. Previously, log + messages that were generated before opening the log file were only + logged to stdout. Closes ticket 6938. + - Add a TruncateLogFile option to overwrite logs instead of + appending to them. Closes ticket 5583. + - Quiet some log messages in the heartbeat and at startup. Closes + ticket 14950. + + o Minor features (portability, Solaris): + - Threads are no longer disabled by default on Solaris; we believe + that the versions of Solaris with broken threading support are all + obsolete by now. Resolves ticket 9495. + + o Minor features (relay): + - Re-check our address after we detect a changed IP address from + getsockname(). This ensures that the controller command "GETINFO + address" will report the correct value. Resolves ticket 11582. + Patch from "ra". + - A new AccountingRule option lets Relays set whether they'd like + AccountingMax to be applied separately to inbound and outbound + traffic, or applied to the sum of inbound and outbound traffic. + Resolves ticket 961. Patch by "chobe". + - When identity keypair is generated for first time, log a + congratulatory message that links to the new relay lifecycle + document. Implements feature 10427. + + o Minor features (security, memory wiping): + - Ensure we securely wipe keys from memory after + crypto_digest_get_digest and init_curve25519_keypair_from_file + have finished using them. Resolves ticket 13477. + + o Minor features (security, out-of-memory handling): + - When handling an out-of-memory condition, allocate less memory for + temporary data structures. Fixes issue 10115. + - When handling an out-of-memory condition, consider more types of + buffers, including those on directory connections, and zlib + buffers. Resolves ticket 11792. + + o Minor features (stability): + - Add assertions in our hash-table iteration code to check for + corrupted values that could cause infinite loops. Closes + ticket 11737. + + o Minor features (systemd): + - Various improvements and modernizations in systemd hardening + support. Closes ticket 13805. Patch from Craig Andrews. + - Where supported, when running with systemd, report successful + startup to systemd. Part of ticket 11016. Patch by Michael Scherer. + - When running with systemd, support systemd watchdog messages. Part + of ticket 11016. Patch by Michael Scherer. + + o Minor features (testing networks): + - Add the TestingDirAuthVoteExit option, which lists nodes to assign + the "Exit" flag regardless of their uptime, bandwidth, or exit + policy. TestingTorNetwork must be set for this option to have any + effect. Previously, authorities would take up to 35 minutes to + give nodes the Exit flag in a test network. Partially implements + ticket 13161. + - Drop the minimum RendPostPeriod on a testing network to 5 seconds, + and the default on a testing network to 2 minutes. Drop the + MIN_REND_INITIAL_POST_DELAY on a testing network to 5 seconds, but + keep the default on a testing network at 30 seconds. This reduces + HS bootstrap time to around 25 seconds. Also, change the default + time in test-network.sh to match. Closes ticket 13401. Patch + by "teor". + - Create TestingDirAuthVoteHSDir to correspond to + TestingDirAuthVoteExit/Guard. Ensures that authorities vote the + HSDir flag for the listed relays regardless of uptime or ORPort + connectivity. Respects the value of VoteOnHidServDirectoriesV2. + Partial implementation for ticket 14067. Patch by "teor". + + o Minor features (tor2web mode): + - Introduce the config option Tor2webRendezvousPoints, which allows + clients in Tor2webMode to select a specific Rendezvous Point to be + used in HS circuits. This might allow better performance for + Tor2Web nodes. Implements ticket 12844. + + o Minor features (transparent proxy): + - Update the transparent proxy option checks to allow for both ipfw + and pf on OS X. Closes ticket 14002. + - Use the correct option when using IPv6 with transparent proxy + support on Linux. Resolves 13808. Patch by Francisco Blas + Izquierdo Riera. + + o Minor features (validation): + - Check all date/time values passed to tor_timegm and + parse_rfc1123_time for validity, taking leap years into account. + Improves HTTP header validation. Implemented with bug 13476. + - In correct_tm(), limit the range of values returned by system + localtime(_r) and gmtime(_r) to be between the years 1 and 8099. + This means we don't have to deal with negative or too large dates, + even if a clock is wrong. Otherwise we might fail to read a file + written by us which includes such a date. Fixes bug 13476. + - Stop allowing invalid address patterns like "*/24" that contain + both a wildcard address and a bit prefix length. This affects all + our address-range parsing code. Fixes bug 7484; bugfix + on 0.0.2pre14. + + o Minor bugfixes (bridge clients): + - When configured to use a bridge without an identity digest (not + recommended), avoid launching an extra channel to it when + bootstrapping. Fixes bug 7733; bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (bridges): + - When DisableNetwork is set, do not launch pluggable transport + plugins, and if any are running, terminate them. Fixes bug 13213; + bugfix on 0.2.3.6-alpha. + + o Minor bugfixes (C correctness): + - Fix several instances of possible integer overflow/underflow/NaN. + Fixes bug 13104; bugfix on 0.2.3.1-alpha and later. Patches + from "teor". + - In circuit_build_times_calculate_timeout() in circuitstats.c, + avoid dividing by zero in the pareto calculations. This traps + under clang's "undefined-trap" sanitizer. Fixes bug 13290; bugfix + on 0.2.2.2-alpha. + - Fix an integer overflow in format_time_interval(). Fixes bug + 13393; bugfix on 0.2.0.10-alpha. + - Set the correct day of year value when the system's localtime(_r) + or gmtime(_r) functions fail to set struct tm. Not externally + visible. Fixes bug 13476; bugfix on 0.0.2pre14. + - Avoid unlikely signed integer overflow in tor_timegm on systems + with 32-bit time_t. Fixes bug 13476; bugfix on 0.0.2pre14. + + o Minor bugfixes (certificate handling): + - If an authority operator accidentally makes a signing certificate + with a future publication time, do not discard its real signing + certificates. Fixes bug 11457; bugfix on 0.2.0.3-alpha. + - Remove any old authority certificates that have been superseded + for at least two days. Previously, we would keep superseded + certificates until they expired, if they were published close in + time to the certificate that superseded them. Fixes bug 11454; + bugfix on 0.2.1.8-alpha. + + o Minor bugfixes (client): + - Fix smartlist_choose_node_by_bandwidth() so that relays with the + BadExit flag are not considered worthy candidates. Fixes bug + 13066; bugfix on 0.1.2.3-alpha. + - Use the consensus schedule for downloading consensuses, and not + the generic schedule. Fixes bug 11679; bugfix on 0.2.2.6-alpha. + - Handle unsupported or malformed SOCKS5 requests properly by + responding with the appropriate error message before closing the + connection. Fixes bugs 12971 and 13314; bugfix on 0.0.2pre13. + + o Minor bugfixes (client, automapping): + - Avoid crashing on torrc lines for VirtualAddrNetworkIPv[4|6] when + no value follows the option. Fixes bug 14142; bugfix on + 0.2.4.7-alpha. Patch by "teor". + - Fix a memory leak when using AutomapHostsOnResolve. Fixes bug + 14195; bugfix on 0.1.0.1-rc. + - Prevent changes to other options from removing the wildcard value + "." from "AutomapHostsSuffixes". Fixes bug 12509; bugfix + on 0.2.0.1-alpha. + - Allow MapAddress and AutomapHostsOnResolve to work together when + an address is mapped into another address type (like .onion) that + must be automapped at resolve time. Fixes bug 7555; bugfix + on 0.2.0.1-alpha. + + o Minor bugfixes (client, bridges): + - When we are using bridges and we had a network connectivity + problem, only retry connecting to our currently configured + bridges, not all bridges we know about and remember using. Fixes + bug 14216; bugfix on 0.2.2.17-alpha. + + o Minor bugfixes (client, DNS): + - Report the correct cached DNS expiration times on SOCKS port or in + DNS replies. Previously, we would report everything as "never + expires." Fixes bug 14193; bugfix on 0.2.3.17-beta. + - Avoid a small memory leak when we find a cached answer for a + reverse DNS lookup in a client-side DNS cache. (Remember, client- + side DNS caching is off by default, and is not recommended.) Fixes + bug 14259; bugfix on 0.2.0.1-alpha. + + o Minor bugfixes (client, IPv6): + - Reject socks requests to literal IPv6 addresses when IPv6Traffic + flag is not set; and not because the NoIPv4Traffic flag was set. + Previously we'd looked at the NoIPv4Traffic flag for both types of + literal addresses. Fixes bug 14280; bugfix on 0.2.4.7-alpha. + + o Minor bugfixes (client, microdescriptors): + - Use a full 256 bits of the SHA256 digest of a microdescriptor when + computing which microdescriptors to download. This keeps us from + erroneous download behavior if two microdescriptor digests ever + have the same first 160 bits. Fixes part of bug 13399; bugfix + on 0.2.3.1-alpha. + - Reset a router's status if its microdescriptor digest changes, + even if the first 160 bits remain the same. Fixes part of bug + 13399; bugfix on 0.2.3.1-alpha. + + o Minor bugfixes (client, torrc): + - Stop modifying the value of our DirReqStatistics torrc option just + because we're not a bridge or relay. This bug was causing Tor + Browser users to write "DirReqStatistics 0" in their torrc files + as if they had chosen to change the config. Fixes bug 4244; bugfix + on 0.2.3.1-alpha. + - When GeoIPExcludeUnknown is enabled, do not incorrectly decide + that our options have changed every time we SIGHUP. Fixes bug + 9801; bugfix on 0.2.4.10-alpha. Patch from "qwerty1". + + o Minor bugfixes (compilation): + - Fix a compilation warning on s390. Fixes bug 14988; bugfix + on 0.2.5.2-alpha. + - Silence clang warnings under --enable-expensive-hardening, + including implicit truncation of 64 bit values to 32 bit, const + char assignment to self, tautological compare, and additional + parentheses around equality tests. Fixes bug 13577; bugfix + on 0.2.5.4-alpha. + - Fix a clang warning about checking whether an address in the + middle of a structure is NULL. Fixes bug 14001; bugfix + on 0.2.1.2-alpha. + - The address of an array in the middle of a structure will always + be non-NULL. clang recognises this and complains. Disable the + tautologous and redundant check to silence this warning. Fixes bug + 14001; bugfix on 0.2.1.2-alpha. + - Compile correctly with (unreleased) OpenSSL 1.1.0 headers. + Addresses ticket 14188. + - Build without warnings with the stock OpenSSL srtp.h header, which + has a duplicate declaration of SSL_get_selected_srtp_profile(). + Fixes bug 14220; this is OpenSSL's bug, not ours. + - Do not compile any code related to Tor2Web mode when Tor2Web mode + is not enabled at compile time. Previously, this code was included + in a disabled state. See discussion on ticket 12844. + - Allow our configure script to build correctly with autoconf 2.62 + again. Fixes bug 12693; bugfix on 0.2.5.2-alpha. + - Improve the error message from ./configure to make it clear that + when asciidoc has not been found, the user will have to either add + --disable-asciidoc argument or install asciidoc. Resolves + ticket 13228. + + o Minor bugfixes (controller): + - Report "down" in response to the "GETINFO entry-guards" command + when relays are down with an unreachable_since value. Previously, + we would report "up". Fixes bug 14184; bugfix on 0.1.2.2-alpha. + - Avoid crashing on a malformed EXTENDCIRCUIT command. Fixes bug + 14116; bugfix on 0.2.2.9-alpha. + + o Minor bugfixes (controller): + - Return an error when the second or later arguments of the + "setevents" controller command are invalid events. Previously we + would return success while silently skipping invalid events. Fixes + bug 13205; bugfix on 0.2.3.2-alpha. Reported by "fpxnns". + + o Minor bugfixes (directory authority): + - Allow directory authorities to fetch more data from one another if + they find themselves missing lots of votes. Previously, they had + been bumping against the 10 MB queued data limit. Fixes bug 14261; + bugfix on 0.1.2.5-alpha. + - Do not attempt to download extrainfo documents which we will be + unable to validate with a matching server descriptor. Fixes bug + 13762; bugfix on 0.2.0.1-alpha. + - Fix a bug that was truncating AUTHDIR_NEWDESC events sent to the + control port. Fixes bug 14953; bugfix on 0.2.0.1-alpha. + - Enlarge the buffer to read bwauth generated files to avoid an + issue when parsing the file in dirserv_read_measured_bandwidths(). + Fixes bug 14125; bugfix on 0.2.2.1-alpha. + - When running as a v3 directory authority, advertise that you serve + extra-info documents so that clients who want them can find them + from you too. Fixes part of bug 11683; bugfix on 0.2.0.1-alpha. + + o Minor bugfixes (directory system): + - Always believe that v3 directory authorities serve extra-info + documents, whether they advertise "caches-extra-info" or not. + Fixes part of bug 11683; bugfix on 0.2.0.1-alpha. + - Check the BRIDGE_DIRINFO flag bitwise rather than using equality. + Previously, directories offering BRIDGE_DIRINFO and some other + flag (i.e. microdescriptors or extrainfo) would be ignored when + looking for bridges. Partially fixes bug 13163; bugfix + on 0.2.0.7-alpha. + + o Minor bugfixes (file handling): + - Stop failing when key files are zero-length. Instead, generate new + keys, and overwrite the empty key files. Fixes bug 13111; bugfix + on all versions of Tor. Patch by "teor". + - Stop generating a fresh .old RSA onion key file when the .old file + is missing. Fixes part of 13111; bugfix on 0.0.6rc1. + - Avoid overwriting .old key files with empty key files. + - Skip loading zero-length extrainfo store, router store, stats, + state, and key files. + - Avoid crashing when trying to reload a torrc specified as a + relative path with RunAsDaemon turned on. Fixes bug 13397; bugfix + on 0.2.3.11-alpha. + + o Minor bugfixes (hidden services): + - Close the introduction circuit when we have no more usable intro + points, instead of waiting for it to time out. This also ensures + that no follow-up HS descriptor fetch is triggered when the + circuit eventually times out. Fixes bug 14224; bugfix on 0.0.6. + - When fetching a hidden service descriptor for a down service that + was recently up, do not keep refetching until we try the same + replica twice in a row. Fixes bug 14219; bugfix on 0.2.0.10-alpha. + - Correctly send a controller event when we find that a rendezvous + circuit has finished. Fixes bug 13936; bugfix on 0.1.1.5-alpha. + - Pre-check directory permissions for new hidden-services to avoid + at least one case of "Bug: Acting on config options left us in a + broken state. Dying." Fixes bug 13942; bugfix on 0.0.6pre1. + - When fetching hidden service descriptors, we now check not only + for whether we got the hidden service we had in mind, but also + whether we got the particular descriptors we wanted. This prevents + a class of inefficient but annoying DoS attacks by hidden service + directories. Fixes bug 13214; bugfix on 0.2.1.6-alpha. Reported + by "special". + + o Minor bugfixes (Linux seccomp2 sandbox): + - Make transparent proxy support work along with the seccomp2 + sandbox. Fixes part of bug 13808; bugfix on 0.2.5.1-alpha. Patch + by Francisco Blas Izquierdo Riera. + - Fix a memory leak in tor-resolve when running with the sandbox + enabled. Fixes bug 14050; bugfix on 0.2.5.9-rc. + - Allow glibc fatal errors to be sent to stderr before Tor exits. + Previously, glibc would try to write them to /dev/tty, and the + sandbox would trap the call and make Tor exit prematurely. Fixes + bug 14759; bugfix on 0.2.5.1-alpha. + + o Minor bugfixes (logging): + - Avoid crashing when there are more log domains than entries in + domain_list. Bugfix on 0.2.3.1-alpha. + - Downgrade warnings about RSA signature failures to info log level. + Emit a warning when an extra info document is found incompatible + with a corresponding router descriptor. Fixes bug 9812; bugfix + on 0.0.6rc3. + - Make connection_ap_handshake_attach_circuit() log the circuit ID + correctly. Fixes bug 13701; bugfix on 0.0.6. + + o Minor bugfixes (networking): + - Check for orconns and use connection_or_close_for_error() rather + than connection_mark_for_close() directly in the getsockopt() + failure case of connection_handle_write_impl(). Fixes bug 11302; + bugfix on 0.2.4.4-alpha. + + o Minor bugfixes (parsing): + - Stop accepting milliseconds (or other junk) at the end of + descriptor publication times. Fixes bug 9286; bugfix on 0.0.2pre25. + - Support two-number and three-number version numbers correctly, in + case we change the Tor versioning system in the future. Fixes bug + 13661; bugfix on 0.0.8pre1. + + o Minor bugfixes (portability): + - Fix the ioctl()-based network interface lookup code so that it + will work on systems that have variable-length struct ifreq, for + example Mac OS X. + - Use the correct datatype in the SipHash-2-4 function to prevent + compilers from assuming any sort of alignment. Fixes bug 15436; + bugfix on 0.2.5.3-alpha. + + o Minor bugfixes (preventative security, C safety): + - When reading a hexadecimal, base-32, or base-64 encoded value from + a string, always overwrite the whole output buffer. This prevents + some bugs where we would look at (but fortunately, not reveal) + uninitialized memory on the stack. Fixes bug 14013; bugfix on all + versions of Tor. + - Clear all memory targetted by tor_addr_{to,from}_sockaddr(), not + just the part that's used. This makes it harder for data leak bugs + to occur in the event of other programming failures. Resolves + ticket 14041. + + o Minor bugfixes (relay): + - When generating our family list, remove spaces from around the + entries. Fixes bug 12728; bugfix on 0.2.1.7-alpha. + - If our previous bandwidth estimate was 0 bytes, allow publishing a + new relay descriptor immediately. Fixes bug 13000; bugfix + on 0.1.1.6-alpha. + + o Minor bugfixes (shutdown): + - When shutting down, always call event_del() on lingering read or + write events before freeing them. Otherwise, we risk double-frees + or read-after-frees in event_base_free(). Fixes bug 12985; bugfix + on 0.1.0.2-rc. + + o Minor bugfixes (small memory leaks): + - Avoid leaking memory when using IPv6 virtual address mappings. + Fixes bug 14123; bugfix on 0.2.4.7-alpha. Patch by Tom van + der Woerdt. + + o Minor bugfixes (statistics): + - Increase period over which bandwidth observations are aggregated + from 15 minutes to 4 hours. Fixes bug 13988; bugfix on 0.0.8pre1. + + o Minor bugfixes (systemd support): + - Run correctly under systemd with the RunAsDaemon option set. Fixes + part of bug 14141; bugfix on 0.2.5.7-rc. Patch from Tomasz Torcz. + - Inform the systemd supervisor about more changes in the Tor + process status. Implements part of ticket 14141. Patch from + Tomasz Torcz. + + o Minor bugfixes (testing networks): + - Fix TestingDirAuthVoteGuard to properly give out Guard flags in a + testing network. Fixes bug 13064; bugfix on 0.2.5.2-alpha. + - Stop using the default authorities in networks which provide both + AlternateDirAuthority and AlternateBridgeAuthority. Partially + fixes bug 13163; bugfix on 0.2.0.13-alpha. + + o Minor bugfixes (testing networks, fast startup): + - Allow Tor to build circuits using a consensus with no exits. If + the consensus has no exits (typical of a bootstrapping test + network), allow Tor to build circuits once enough descriptors have + been downloaded. This assists in bootstrapping a testing Tor + network. Fixes bug 13718; bugfix on 0.2.4.10-alpha. Patch + by "teor". + - When V3AuthVotingInterval is low, give a lower If-Modified-Since + header to directory servers. This allows us to obtain consensuses + promptly when the consensus interval is very short. This assists + in bootstrapping a testing Tor network. Fixes parts of bugs 13718 + and 13963; bugfix on 0.2.0.3-alpha. Patch by "teor". + - Stop assuming that private addresses are local when checking + reachability in a TestingTorNetwork. Instead, when testing, assume + all OR connections are remote. (This is necessary due to many test + scenarios running all relays on localhost.) This assists in + bootstrapping a testing Tor network. Fixes bug 13924; bugfix on + 0.1.0.1-rc. Patch by "teor". + - Avoid building exit circuits from a consensus with no exits. Now + thanks to our fix for 13718, we accept a no-exit network as not + wholly lost, but we need to remember not to try to build exit + circuits on it. Closes ticket 13814; patch by "teor". + - Stop requiring exits to have non-zero bandwithcapacity in a + TestingTorNetwork. Instead, when TestingMinExitFlagThreshold is 0, + ignore exit bandwidthcapacity. This assists in bootstrapping a + testing Tor network. Fixes parts of bugs 13718 and 13839; bugfix + on 0.2.0.3-alpha. Patch by "teor". + - Add "internal" to some bootstrap statuses when no exits are + available. If the consensus does not contain Exits, Tor will only + build internal circuits. In this case, relevant statuses will + contain the word "internal" as indicated in the Tor control- + spec.txt. When bootstrap completes, Tor will be ready to build + internal circuits. If a future consensus contains Exits, exit + circuits may become available. Fixes part of bug 13718; bugfix on + 0.2.4.10-alpha. Patch by "teor". + - Decrease minimum consensus interval to 10 seconds when + TestingTorNetwork is set, or 5 seconds for the first consensus. + Fix assumptions throughout the code that assume larger intervals. + Fixes bugs 13718 and 13823; bugfix on 0.2.0.3-alpha. Patch + by "teor". + - Avoid excluding guards from path building in minimal test + networks, when we're in a test network and excluding guards would + exclude all relays. This typically occurs in incredibly small tor + networks, and those using "TestingAuthVoteGuard *". Fixes part of + bug 13718; bugfix on 0.1.1.11-alpha. Patch by "teor". + + o Minor bugfixes (testing): + - Avoid a side-effect in a tor_assert() in the unit tests. Fixes bug + 15188; bugfix on 0.1.2.3-alpha. Patch from Tom van der Woerdt. + - Stop spawn test failures due to a race condition between the + SIGCHLD handler updating the process status, and the test reading + it. Fixes bug 13291; bugfix on 0.2.3.3-alpha. + - Avoid passing an extra backslash when creating a temporary + directory for running the unit tests on Windows. Fixes bug 12392; + bugfix on 0.2.2.25-alpha. Patch from Gisle Vanem. + + o Minor bugfixes (TLS): + - Check more thoroughly throughout the TLS code for possible + unlogged TLS errors. Possible diagnostic or fix for bug 13319. + + o Minor bugfixes (transparent proxy): + - Use getsockname, not getsockopt, to retrieve the address for a + TPROXY-redirected connection. Fixes bug 13796; bugfix + on 0.2.5.2-alpha. + + o Minor bugfixes (windows): + - Remove code to special-case handling of NTE_BAD_KEYSET when + acquiring windows CryptoAPI context. This error can't actually + occur for the parameters we're providing. Fixes bug 10816; bugfix + on 0.0.2pre26. + + o Minor bugfixes (zlib): + - Avoid truncating a zlib stream when trying to finalize it with an + empty output buffer. Fixes bug 11824; bugfix on 0.1.1.23. + + o Code simplification and refactoring: + - Change the entry_is_live() function to take named bitfield + elements instead of an unnamed list of booleans. Closes + ticket 12202. + - Refactor and unit-test entry_is_time_to_retry() in entrynodes.c. + Resolves ticket 12205. + - Use calloc and reallocarray functions instead of multiply- + then-malloc. This makes it less likely for us to fall victim to an + integer overflow attack when allocating. Resolves ticket 12855. + - Use the standard macro name SIZE_MAX, instead of our + own SIZE_T_MAX. + - Document usage of the NO_DIRINFO and ALL_DIRINFO flags clearly in + functions which take them as arguments. Replace 0 with NO_DIRINFO + in a function call for clarity. Seeks to prevent future issues + like 13163. + - Avoid 4 null pointer errors under clang static analysis by using + tor_assert() to prove that the pointers aren't null. Fixes + bug 13284. + - Rework the API of policies_parse_exit_policy() to use a bitmask to + represent parsing options, instead of a confusing mess of + booleans. Resolves ticket 8197. + - Introduce a helper function to parse ExitPolicy in + or_options_t structure. + - Move fields related to isolating and configuring client ports into + a shared structure. Previously, they were duplicated across + port_cfg_t, listener_connection_t, and edge_connection_t. Failure + to copy them correctly had been the cause of at least one bug in + the past. Closes ticket 8546. + - Refactor the get_interface_addresses_raw() doom-function into + multiple smaller and simpler subfunctions. Cover the resulting + subfunctions with unit-tests. Fixes a significant portion of + issue 12376. + - Remove workaround in dirserv_thinks_router_is_hs_dir() that was + only for version <= 0.2.2.24 which is now deprecated. Closes + ticket 14202. + - Remove a test for a long-defunct broken version-one + directory server. + - Refactor main loop to extract the 'loop' part. This makes it + easier to run Tor under Shadow. Closes ticket 15176. + - Stop using can_complete_circuits as a global variable; access it + with a function instead. + - Avoid using operators directly as macro arguments: this lets us + apply coccinelle transformations to our codebase more directly. + Closes ticket 13172. + - Combine the functions used to parse ClientTransportPlugin and + ServerTransportPlugin into a single function. Closes ticket 6456. + - Add inline functions and convenience macros for inspecting channel + state. Refactor the code to use convenience macros instead of + checking channel state directly. Fixes issue 7356. + - Document all members of was_router_added_t and rename + ROUTER_WAS_NOT_NEW to ROUTER_IS_ALREADY_KNOWN to make it less + confusable with ROUTER_WAS_TOO_OLD. Fixes issue 13644. + - In connection_exit_begin_conn(), use END_CIRC_REASON_TORPROTOCOL + constant instead of hardcoded value. Fixes issue 13840. + - Refactor our generic strmap and digestmap types into a single + implementation, so that we can add a new digest256map + type trivially. + + o Documentation: + - Add a doc/TUNING document with tips for handling large numbers of + TCP connections when running busy Tor relay. Update the warning + message to point to this file when running out of sockets + operating system is allowing to use simultaneously. Resolves + ticket 9708. + - Adding section on OpenBSD to our TUNING document. Thanks to mmcc + for writing the OpenBSD-specific tips. Resolves ticket 13702. + - Make the tor-resolve documentation match its help string and its + options. Resolves part of ticket 14325. + - Log a more useful error message from tor-resolve when failing to + look up a hidden service address. Resolves part of ticket 14325. + - Document the bridge-authority-only 'networkstatus-bridges' file. + Closes ticket 13713; patch from "tom". + - Fix typo in PredictedPortsRelevanceTime option description in + manpage. Resolves issue 13707. + - Stop suggesting that users specify relays by nickname: it isn't a + good idea. Also, properly cross-reference how to specify relays in + all parts of manual documenting options that take a list of + relays. Closes ticket 13381. + - Clarify the HiddenServiceDir option description in manpage to make + it clear that relative paths are taken with respect to the current + working directory. Also clarify that this behavior is not + guaranteed to remain indefinitely. Fixes issue 13913. + + o Distribution (systemd): + - systemd unit file: only allow tor to write to /var/lib/tor and + /var/log/tor. The rest of the filesystem is accessible for reading + only. Patch by intrigeri; resolves ticket 12751. + - systemd unit file: ensure that the process and all its children + can never gain new privileges. Patch by intrigeri; resolves + ticket 12939. + - systemd unit file: set up /var/run/tor as writable for the Tor + service. Patch by intrigeri; resolves ticket 13196. + + o Downgraded warnings: + - Don't warn when we've attempted to contact a relay using the wrong + ntor onion key. Closes ticket 9635. + + o Removed code: + - Remove some lingering dead code that once supported mempools. + Mempools were disabled by default in 0.2.5, and removed entirely + in 0.2.6.3-alpha. Closes more of ticket 14848; patch + by "cypherpunks". + + o Removed features (directory authorities): + - Remove code that prevented authorities from listing Tor relays + affected by CVE-2011-2769 as guards. These relays are already + rejected altogether due to the minimum version requirement of + 0.2.3.16-alpha. Closes ticket 13152. + - The "AuthDirRejectUnlisted" option no longer has any effect, as + the fingerprints file (approved-routers) has been deprecated. + - Directory authorities do not support being Naming dirauths anymore. + The "NamingAuthoritativeDir" config option is now obsolete. + - Directory authorities do not support giving out the BadDirectory + flag anymore. + - Directory authorities no longer advertise or support consensus + methods 1 through 12 inclusive. These consensus methods were + obsolete and/or insecure: maintaining the ability to support them + served no good purpose. Implements part of proposal 215; closes + ticket 10163. + + o Removed features: + - To avoid confusion with the "ExitRelay" option, "ExitNode" is no + longer silently accepted as an alias for "ExitNodes". + - The --enable-mempool and --enable-buf-freelists options, which + were originally created to work around bad malloc implementations, + no longer exist. They were off-by-default in 0.2.5. Closes + ticket 14848. + - We no longer remind the user about configuration options that have + been obsolete since 0.2.3.x or earlier. Patch by Adrien Bak. + - Remove our old, non-weighted bandwidth-based node selection code. + Previously, we used it as a fallback when we couldn't perform + weighted bandwidth-based node selection. But that would only + happen in the cases where we had no consensus, or when we had a + consensus generated by buggy or ancient directory authorities. In + either case, it's better to use the more modern, better maintained + algorithm, with reasonable defaults for the weights. Closes + ticket 13126. + - Remove the --disable-curve25519 configure option. Relays and + clients now are required to support curve25519 and the + ntor handshake. + - The old "StrictEntryNodes" and "StrictExitNodes" options, which + used to be deprecated synonyms for "StrictNodes", are now marked + obsolete. Resolves ticket 12226. + - Clients don't understand the BadDirectory flag in the consensus + anymore, and ignore it. + + o Removed platform support: + - We no longer include special code to build on Windows CE; as far + as we know, nobody has used Tor on Windows CE in a very long time. + Closes ticket 11446. + + o Testing (test-network.sh): + - Stop using "echo -n", as some shells' built-in echo doesn't + support "-n". Instead, use "/bin/echo -n". Partially fixes + bug 13161. + - Stop an apparent test-network hang when used with make -j2. Fixes + bug 13331. + - Add a --delay option to test-network.sh, which configures the + delay before the chutney network tests for data transmission. + Partially implements ticket 13161. + + o Testing: + - Test that tor does not fail when key files are zero-length. Check + that tor generates new keys, and overwrites the empty key files. + - Test that tor generates new keys when keys are missing + (existing behavior). + - Test that tor does not overwrite key files that already contain + data (existing behavior). Tests bug 13111. Patch by "teor". + - New "make test-stem" target to run stem integration tests. + Requires that the "STEM_SOURCE_DIR" environment variable be set. + Closes ticket 14107. + - Make the test_cmdline_args.py script work correctly on Windows. + Patch from Gisle Vanem. + - Move the slower unit tests into a new "./src/test/test-slow" + binary that can be run independently of the other tests. Closes + ticket 13243. + - New tests for many parts of channel, relay, and circuitmux + functionality. Code by Andrea; part of 9262. + - New tests for parse_transport_line(). Part of ticket 6456. + - In the unit tests, use chgrp() to change the group of the unit + test temporary directory to the current user, so that the sticky + bit doesn't interfere with tests that check directory groups. + Closes 13678. + - Add unit tests for resolve_my_addr(). Part of ticket 12376; patch + by 'rl1987'. + - Refactor the function that chooses guard nodes so that it can more + easily be tested; write some tests for it. + - Fix and re-enable the fgets_eagain unit test. Fixes bug 12503; + bugfix on 0.2.3.1-alpha. Patch from "cypherpunks." + - Create unit tests for format_time_interval(). With bug 13393. + - Add unit tests for tor_timegm signed overflow, tor_timegm and + parse_rfc1123_time validity checks, correct_tm year clamping. Unit + tests (visible) fixes in bug 13476. + - Add a "coverage-html" make target to generate HTML-visualized + coverage results when building with --enable-coverage. (Requires + lcov.) Patch from Kevin Murray. + - Enable the backtrace handler (where supported) when running the + unit tests. + - Revise all unit tests that used the legacy test_* macros to + instead use the recommended tt_* macros. This patch was generated + with coccinelle, to avoid manual errors. Closes ticket 13119. + +Changes in version 0.2.5.11 - 2015-03-17 + Tor 0.2.5.11 is the second stable release in the 0.2.5 series. + + It backports several bugfixes from the 0.2.6 branch, including a + couple of medium-level security fixes for relays and exit nodes. + It also updates the list of directory authorities. + + o Directory authority changes: + - Remove turtles as a directory authority. + - Add longclaw as a new (v3) directory authority. This implements + ticket 13296. This keeps the directory authority count at 9. + - The directory authority Faravahar has a new IP address.

Fixes bug 15088; bugfix on + 0.2.5.1-alpha. Patch from "sanic". + + o Minor features (controller): + - New "GETINFO bw-event-cache" to get information about recent + bandwidth events. Closes ticket 14128. Useful for controllers to + get recent bandwidth history after the fix for ticket 13988. + + o Minor features (geoip): + - Update geoip to the March 3 2015 Maxmind GeoLite2 Country database. + - Update geoip6 to the March 3 2015 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (client, automapping): + - Avoid crashing on torrc lines for VirtualAddrNetworkIPv[4|6] when + no value follows the option.

Previously, they had + been bumping against the 10 MB queued data limit. Fixes bug 14261; + bugfix on 0.1.2.5-alpha. + - Enlarge the buffer to read bwauth generated files to avoid an + issue when parsing the file in dirserv_read_measured_bandwidths(). + Fixes bug 14125; bugfix on 0.2.2.1-alpha. + + o Minor bugfixes (statistics): + - Increase period over which bandwidth observations are aggregated + from 15 minutes to 4 hours. Fixes bug 13988; bugfix on 0.0.8pre1. + + o Minor bugfixes (preventative security, C safety): + - When reading a hexadecimal, base-32, or base-64 encoded value from + a string, always overwrite the whole output buffer. This prevents + some bugs where we would look at (but fortunately, not reveal) + uninitialized memory on the stack.
