Fixes bug 40509; + bugfix on 0.3.5.17. + + o Minor bugfixes (MetricsPort, Prometheus): + - Add double quotes to the label values of the onion service + metrics. Fixes bug 40552; bugfix on 0.4.5.1-alpha. + + +Changes in version 0.4.6.9 - 2021-12-15 + This version fixes several bugs from earlier versions of Tor. One important + piece is the removal of DNS timeout metric from the overload general signal. + See below for more details. + + o Major bugfixes (relay, overload): + - Don't make Tor DNS timeout trigger an overload general state. + These timeouts are different from DNS server timeout. They have to + be seen as timeout related to UX and not because of a network + problem. Fixes bug 40527; bugfix on 0.4.6.1-alpha. + + o Minor feature (reproducible build): + - The repository can now build reproducible tarballs which adds the + build command "make dist-reprod" for that purpose. Closes + ticket 26299. + + o Minor features (compilation): + - Give an error message if trying to build with a version of + LibreSSL known not to work with Tor. (There's an incompatibility + with LibreSSL versions 3.2.1 through 3.4.0 inclusive because of + their incompatibility with OpenSSL 1.1.1's TLSv1.3 APIs.) Closes + ticket 40511. + + o Minor features (fallbackdir): + - Regenerate fallback directories generated on December 15, 2021. + + o Minor features (geoip data): + - Update the geoip files to match the IPFire Location Database, as + retrieved on 2021/12/15. + + o Minor bugfixes (compilation): + - Fix our configuration logic to detect whether we had OpenSSL 3: + previously, our logic was reversed. This has no other effect than + to change whether we suppress deprecated API warnings. Fixes bug + 40429; bugfix on 0.3.5.13. + + o Minor bugfixes (relay): + - Reject IPv6-only DirPorts. Our reachability self-test forces + DirPorts to be IPv4, but our configuration parser allowed them to + be IPv6-only, which led to an assertion failure. Fixes bug 40494; + bugfix on 0.4.5.1-alpha. + + o Documentation (man, relay): + - Missing "OverloadStatistics" in tor.1 manpage. Fixes bug 40504; + bugfix on 0.4.6.1-alpha. + + +Changes in version 0.4.6.8 - 2021-10-26 + This version fixes several bugs from earlier versions of Tor. One + highlight is a fix on how we track DNS timeouts to report general + relay overload. + + o Major bugfixes (relay, overload state): + - Relays report the general overload state for DNS timeout errors + only if X% of all DNS queries over Y seconds are errors. Before + that, it only took 1 timeout to report the overload state which + was just too low of a threshold. The X and Y values are 1% and 10 + minutes respectively but they are also controlled by consensus + parameters. Fixes bug 40491; bugfix on 0.4.6.1-alpha. + + o Minor features (fallbackdir): + - Regenerate fallback directories for October 2021. Closes + ticket 40493. + + o Minor features (testing): + - On a testing network, relays can now use the + TestingMinTimeToReportBandwidth option to change the smallest + amount of time over which they're willing to report their observed + maximum bandwidth. Previously, this was fixed at 1 day. For + safety, values under 2 hours are only supported on testing + networks. Part of a fix for ticket 40337. + - Relays on testing networks no longer rate-limit how frequently + they are willing to report new bandwidth measurements. Part of a + fix for ticket 40337. + - Relays on testing networks now report their observed bandwidths + immediately from startup. Previously, they waited until they had + been running for a full day. Closes ticket 40337. + + o Minor bugfix (onion service): + - Do not flag an HSDir as non-running in case the descriptor upload + or fetch fails. An onion service closes pending directory + connections before uploading a new descriptor which can thus lead + to wrongly flagging many relays and thus affecting circuit building + path selection. Fixes bug 40434; bugfix on 0.2.0.13-alpha. + - Improve logging when a bad HS version is given. Fixes bug 40476; + bugfix on 0.4.6.1-alpha. + + o Minor bugfix (CI, onion service): + - Exclude onion service version 2 Stem tests in our CI. Fixes bug 40500; + bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (compatibility): + - Fix compatibility with the most recent Libevent versions, which no + longer have an evdns_set_random_bytes() function. Because this + function has been a no-op since Libevent 2.0.4-alpha, it is safe + for us to just stop calling it. Fixes bug 40371; bugfix + on 0.2.1.7-alpha. + + o Minor bugfixes (onion service, TROVE-2021-008): + - Only log v2 access attempts once total, in order to not pollute + the logs with warnings and to avoid recording the times on disk + when v2 access was attempted. Note that the onion address was + _never_ logged. This counts as a Low-severity security issue. + Fixes bug 40474; bugfix on 0.4.5.8. + + +Changes in version 0.4.6.7 - 2021-08-16 + This version fixes several bugs from earlier versions of Tor, + including one that could lead to a denial-of-service attack. Everyone + running an earlier version, whether as a client, a relay, or an onion + service, should upgrade to Tor 0.3.5.16, 0.4.5.10, or 0.4.6.7. + + o Major bugfixes (cryptography, security): + - Resolve an assertion failure caused by a behavior mismatch between + our batch-signature verification code and our single-signature + verification code. This assertion failure could be triggered + remotely, leading to a denial of service attack. We fix this issue + by disabling batch verification. Fixes bug 40078; bugfix on + 0.2.6.1-alpha. This issue is also tracked as TROVE-2021-007 and + CVE-2021-38385. Found by Henry de Valence. + + o Minor feature (fallbackdir): + - Regenerate fallback directories list. Close ticket 40447. + + o Minor features (geoip data): + - Update the geoip files to match the IPFire Location Database, as + retrieved on 2021/08/12. + + o Minor bugfix (crypto): + - Disable the unused batch verification feature of ed25519-donna. + Fixes bug 40078; bugfix on 0.2.6.1-alpha. Found by Henry + de Valence. + + o Minor bugfixes (onion service): + - Send back the extended SOCKS error 0xF6 (Onion Service Invalid + Address) for a v2 onion address. Fixes bug 40421; bugfix + on 0.4.6.2-alpha. + + o Minor bugfixes (relay): + - Reduce the compression level for data streaming from HIGH to LOW + in order to reduce CPU load on the directory relays. Fixes bug + 40301; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (timekeeping): + - Calculate the time of day correctly on systems where the time_t + type includes leap seconds. (This is not the case on most + operating systems, but on those where it occurs, our tor_timegm + function did not correctly invert the system's gmtime function, + which could result in assertion failures when calculating voting + schedules.) Fixes bug 40383; bugfix on 0.2.0.3-alpha. + + +Changes in version 0.4.6.6 - 2021-06-30 + Tor 0.4.6.6 makes several small fixes on 0.4.6.5, including one that + allows Tor to build correctly on older versions of GCC. You should + upgrade to this version if you were having trouble building Tor + 0.4.6.5; otherwise, there is probably no need. + + o Minor bugfixes (compilation): + - Fix a compilation error when trying to build Tor with a compiler + that does not support const variables in static initializers. + Fixes bug 40410; bugfix on 0.4.6.5. + - Suppress a strict-prototype warning when building with some + versions of NSS. Fixes bug 40409; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (testing): + - Enable the deterministic RNG for unit tests that covers the + address set bloomfilter-based API's. Fixes bug 40419; bugfix + on 0.3.3.2-alpha. + + +Changes in version 0.4.6.5 - 2021-06-14 + Tor 0.4.6.5 is the first stable release in its series. The 0.4.6.x + series includes numerous features and bugfixes, including a significant + improvement to our circuit timeout algorithm that should improve + observed client performance, and a way for relays to report when they are + overloaded. + + This release also includes security fixes for several security issues, + including a denial-of-service attack against onion service clients, + and another denial-of-service attack against relays. Everybody should + upgrade to one of 0.3.5.15, 0.4.4.9, 0.4.5.9, or 0.4.6.5. + + Below are the changes since 0.4.6.4-rc. For a complete list of changes + since 0.4.5.8, see the ReleaseNotes file. + + o Major bugfixes (security): + - Don't allow relays to spoof RELAY_END or RELAY_RESOLVED cell on + half-closed streams. Previously, clients failed to validate which + hop sent these cells: this would allow a relay on a circuit to end + a stream that wasn't actually built with it. Fixes bug 40389; + bugfix on 0.3.5.1-alpha. This issue is also tracked as TROVE-2021- + 003 and CVE-2021-34548. + + o Major bugfixes (security, defense-in-depth): + - Detect more failure conditions from the OpenSSL RNG code. + Previously, we would detect errors from a missing RNG + implementation, but not failures from the RNG code itself. + Fortunately, it appears those failures do not happen in practice + when Tor is using OpenSSL's default RNG implementation. Fixes bug + 40390; bugfix on 0.2.8.1-alpha. This issue is also tracked as + TROVE-2021-004. Reported by Jann Horn at Google's Project Zero. + + o Major bugfixes (security, denial of service): + - Resist a hashtable-based CPU denial-of-service attack against + relays. Previously we used a naive unkeyed hash function to look + up circuits in a circuitmux object. An attacker could exploit this + to construct circuits with chosen circuit IDs, to create + collisions and make the hash table inefficient. Now we use a + SipHash construction here instead. Fixes bug 40391; bugfix on + 0.2.4.4-alpha. This issue is also tracked as TROVE-2021-005 and + CVE-2021-34549. Reported by Jann Horn from Google's Project Zero. + - Fix an out-of-bounds memory access in v3 onion service descriptor + parsing. An attacker could exploit this bug by crafting an onion + service descriptor that would crash any client that tried to visit + it. Fixes bug 40392; bugfix on 0.3.0.1-alpha. This issue is also + tracked as TROVE-2021-006 and CVE-2021-34550. Reported by Sergei + Glazunov from Google's Project Zero. + + o Minor features (geoip data): + - Update the geoip files to match the IPFire Location Database, as + retrieved on 2021/06/10. + + o Minor features (logging, diagnostic): + - Log decompression failures at a higher severity level, since they + can help provide missing context for other warning messages. We + rate-limit these messages, to avoid flooding the logs if they + begin to occur frequently. Closes ticket 40175. + + +Changes in version 0.4.6.4-rc - 2021-05-28 + Tor 0.4.6.4-rc fixes a few bugs from previous releases. This, we hope, + the final release candidate in its series: unless major new issues are + found, the next release will be stable. + + o Minor features (compatibility): + - Remove an assertion function related to TLS renegotiation. It was + used nowhere outside the unit tests, and it was breaking + compilation with recent alpha releases of OpenSSL 3.0.0. Closes + ticket 40399. + + o Minor bugfixes (consensus handling): + - Avoid a set of bugs that could be caused by inconsistently + preferring an out-of-date consensus stored in a stale directory + cache over a more recent one stored on disk as the latest + consensus. Fixes bug 40375; bugfix on 0.3.1.1-alpha. + + o Minor bugfixes (control, sandbox): + - Allow the control command SAVECONF to succeed when the seccomp + sandbox is enabled, and make SAVECONF keep only one backup file to + simplify implementation. Previously SAVECONF allowed a large + number of backup files, which made it incompatible with the + sandbox. Fixes bug 40317; bugfix on 0.2.5.4-alpha. Patch by + Daniel Pinto. + + o Minor bugfixes (metrics port): + - Fix a bug that made tor try to re-bind() on an already open + MetricsPort every 60 seconds. Fixes bug 40370; bugfix + on 0.4.5.1-alpha. + + o Removed features: + - Remove unneeded code for parsing private keys in directory + documents. This code was only used for client authentication in v2 + onion services, which are now unsupported. Closes ticket 40374. + + +Changes in version 0.4.5.8 - 2021-05-10 + Tor 0.4.5.8 fixes several bugs in earlier version, backporting fixes + from the 0.4.6.x series. + + o Minor features (compatibility, Linux seccomp sandbox, backport from 0.4.6.3-rc): + - Add a workaround to enable the Linux sandbox to work correctly + with Glibc 2.33. This version of Glibc has started using the + fstatat() system call, which previously our sandbox did not allow. + Closes ticket 40382; see the ticket for a discussion of trade-offs. + + o Minor features (compilation, backport from 0.4.6.3-rc): + - Make the autoconf script build correctly with autoconf versions + 2.70 and later. Closes part of ticket 40335. + + o Minor features (fallback directory list, backport from 0.4.6.2-alpha): + - Regenerate the list of fallback directories to contain a new set + of 200 relays. Closes ticket 40265. + + o Minor features (geoip data): + - Update the geoip files to match the IPFire Location Database, as + retrieved on 2021/05/07. + + o Minor features (onion services): + - Add warning message when connecting to now deprecated v2 onion + services. As announced, Tor 0.4.5.x is the last series that will + support v2 onions. Closes ticket 40373. + + o Minor bugfixes (bridge, pluggable transport, backport from 0.4.6.2-alpha): + - Fix a regression that made it impossible start Tor using a bridge + line with a transport name and no fingerprint. Fixes bug 40360; + bugfix on 0.4.5.4-rc. + + o Minor bugfixes (build, cross-compilation, backport from 0.4.6.3-rc): + - Allow a custom "ar" for cross-compilation. Our previous build + script had used the $AR environment variable in most places, but + it missed one. Fixes bug 40369; bugfix on 0.4.5.1-alpha. + + o Minor bugfixes (channel, DoS, backport from 0.4.6.2-alpha): + - Fix a non-fatal BUG() message due to a too-early free of a string, + when listing a client connection from the DoS defenses subsystem. + Fixes bug 40345; bugfix on 0.4.3.4-rc. + + o Minor bugfixes (compiler warnings, backport from 0.4.6.3-rc): + - Fix an indentation problem that led to a warning from GCC 11.1.1. + Fixes bug 40380; bugfix on 0.3.0.1-alpha. + + o Minor bugfixes (controller, backport from 0.4.6.1-alpha): + - Fix a "BUG" warning that would appear when a controller chooses + the first hop for a circuit, and that circuit completes. Fixes bug + 40285; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (onion service, client, memory leak, backport from 0.4.6.3-rc): + - Fix a bug where an expired cached descriptor could get overwritten + with a new one without freeing it, leading to a memory leak. Fixes + bug 40356; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (testing, BSD, backport from 0.4.6.2-alpha): + - Fix pattern-matching errors when patterns expand to invalid paths + on BSD systems. Fixes bug 40318; bugfix on 0.4.5.1-alpha. Patch by + Daniel Pinto. + + +Changes in version 0.4.6.3-rc - 2021-05-10 + Tor 0.4.6.3-rc is the first release candidate in its series. It fixes + a few small bugs from previous versions, and adds a better error + message when trying to use (no longer supported) v2 onion services. + + Though we anticipate that we'll be doing a bit more clean-up between + now and the stable release, we expect that our remaining changes will + be fairly simple. There will likely be at least one more release + candidate before 0.4.6.x is stable. + + o Major bugfixes (onion service, control port): + - Make the ADD_ONION command properly configure client authorization. + Before this fix, the created onion failed to add the client(s). + Fixes bug 40378; bugfix on 0.4.6.1-alpha. + + o Minor features (compatibility, Linux seccomp sandbox): + - Add a workaround to enable the Linux sandbox to work correctly + with Glibc 2.33.

Fixes bug 40552; bugfix on 0.4.5.1-alpha. + + +Changes in version 0.4.6.9 - 2021-12-15 + This version fixes several bugs from earlier versions of Tor. One important + piece is the removal of DNS timeout metric from the overload general signal. + See below for more details. + + o Major bugfixes (relay, overload): + - Don't make Tor DNS timeout trigger an overload general state. + These timeouts are different from DNS server timeout. They have to + be seen as timeout related to UX and not because of a network + problem. Fixes bug 40527; bugfix on 0.4.6.1-alpha. + + o Minor feature (reproducible build): + - The repository can now build reproducible tarballs which adds the + build command "make dist-reprod" for that purpose. Closes + ticket 26299. + + o Minor features (compilation): + - Give an error message if trying to build with a version of + LibreSSL known not to work with Tor. (There's an incompatibility + with LibreSSL versions 3.2.1 through 3.4.0 inclusive because of + their incompatibility with OpenSSL 1.1.1's TLSv1.3 APIs.) Closes + ticket 40511. + + o Minor features (fallbackdir): + - Regenerate fallback directories generated on December 15, 2021. + + o Minor features (geoip data): + - Update the geoip files to match the IPFire Location Database, as + retrieved on 2021/12/15. + + o Minor bugfixes (compilation): + - Fix our configuration logic to detect whether we had OpenSSL 3: + previously, our logic was reversed. This has no other effect than + to change whether we suppress deprecated API warnings. Fixes bug + 40429; bugfix on 0.3.5.13. + + o Minor bugfixes (relay): + - Reject IPv6-only DirPorts. Our reachability self-test forces + DirPorts to be IPv4, but our configuration parser allowed them to + be IPv6-only, which led to an assertion failure. Fixes bug 40494; + bugfix on 0.4.5.1-alpha. + + o Documentation (man, relay): + - Missing "OverloadStatistics" in tor.1 manpage. Fixes bug 40504; + bugfix on 0.4.6.1-alpha. + + +Changes in version 0.4.6.8 - 2021-10-26 + This version fixes several bugs from earlier versions of Tor. One + highlight is a fix on how we track DNS timeouts to report general + relay overload. + + o Major bugfixes (relay, overload state): + - Relays report the general overload state for DNS timeout errors + only if X% of all DNS queries over Y seconds are errors. Before + that, it only took 1 timeout to report the overload state which + was just too low of a threshold. The X and Y values are 1% and 10 + minutes respectively but they are also controlled by consensus + parameters. Fixes bug 40491; bugfix on 0.4.6.1-alpha. + + o Minor features (fallbackdir): + - Regenerate fallback directories for October 2021. Closes + ticket 40493. + + o Minor features (testing): + - On a testing network, relays can now use the + TestingMinTimeToReportBandwidth option to change the smallest + amount of time over which they're willing to report their observed + maximum bandwidth. Previously, this was fixed at 1 day. For + safety, values under 2 hours are only supported on testing + networks. Part of a fix for ticket 40337. + - Relays on testing networks no longer rate-limit how frequently + they are willing to report new bandwidth measurements. Part of a + fix for ticket 40337. + - Relays on testing networks now report their observed bandwidths + immediately from startup. Previously, they waited until they had + been running for a full day. Closes ticket 40337. + + o Minor bugfix (onion service): + - Do not flag an HSDir as non-running in case the descriptor upload + or fetch fails. An onion service closes pending directory + connections before uploading a new descriptor which can thus lead + to wrongly flagging many relays and thus affecting circuit building + path selection. Fixes bug 40434; bugfix on 0.2.0.13-alpha. + - Improve logging when a bad HS version is given. Fixes bug 40476; + bugfix on 0.4.6.1-alpha. + + o Minor bugfix (CI, onion service): + - Exclude onion service version 2 Stem tests in our CI. Fixes bug 40500; + bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (compatibility): + - Fix compatibility with the most recent Libevent versions, which no + longer have an evdns_set_random_bytes() function. Because this + function has been a no-op since Libevent 2.0.4-alpha, it is safe + for us to just stop calling it. Fixes bug 40371; bugfix + on 0.2.1.7-alpha. + + o Minor bugfixes (onion service, TROVE-2021-008): + - Only log v2 access attempts once total, in order to not pollute + the logs with warnings and to avoid recording the times on disk + when v2 access was attempted. Note that the onion address was + _never_ logged. This counts as a Low-severity security issue. + Fixes bug 40474; bugfix on 0.4.5.8. + + +Changes in version 0.4.6.7 - 2021-08-16 + This version fixes several bugs from earlier versions of Tor, including one + that could lead to a denial-of-service attack. Everyone running an earlier + version, whether as a client, a relay, or an onion service, should upgrade + to Tor 0.3.5.16, 0.4.5.10, or 0.4.6.7. + + o Major bugfixes (cryptography, security): + - Resolve an assertion failure caused by a behavior mismatch between our + batch-signature verification code and our single-signature verification + code. This assertion failure could be triggered remotely, leading to a + denial of service attack. We fix this issue by disabling batch + verification. Fixes bug 40078; bugfix on 0.2.6.1-alpha. This issue is + also tracked as TROVE-2021-007 and CVE-2021-38385. Found by Henry de + Valence. + + o Minor feature (fallbackdir): + - Regenerate fallback directories list. Close ticket 40447. + + o Minor features (geoip data): + - Update the geoip files to match the IPFire Location Database, + as retrieved on 2021/08/12. + + o Minor bugfix (crypto): + - Disable the unused batch verification feature of ed25519-donna. Fixes + bug 40078; bugfix on 0.2.6.1-alpha. Found by Henry de Valence. + + o Minor bugfixes (onion service): + - Send back the extended SOCKS error 0xF6 (Onion Service Invalid Address) + for a v2 onion address. Fixes bug 40421; bugfix on 0.4.6.2-alpha. + + o Minor bugfixes (relay): + - Reduce the compression level for data streaming from HIGH to LOW in + order to reduce CPU load on the directory relays. Fixes bug 40301; + bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (timekeeping): + - Calculate the time of day correctly on systems where the time_t + type includes leap seconds. (This is not the case on most + operating systems, but on those where it occurs, our tor_timegm + function did not correctly invert the system's gmtime function, + which could result in assertion failures when calculating + voting schedules.) Fixes bug 40383; bugfix on 0.2.0.3-alpha. + + +Changes in version 0.4.6.6 - 2021-06-30 + Tor 0.4.6.6 makes several small fixes on 0.4.6.5, including one that + allows Tor to build correctly on older versions of GCC. You should + upgrade to this version if you were having trouble building Tor + 0.4.6.5; otherwise, there is probably no need. + + o Minor bugfixes (compilation): + - Fix a compilation error when trying to build Tor with a compiler + that does not support const variables in static initializers. + Fixes bug 40410; bugfix on 0.4.6.5. + - Suppress a strict-prototype warning when building with some + versions of NSS. Fixes bug 40409; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (testing): + - Enable the deterministic RNG for unit tests that covers the + address set bloomfilter-based API's. Fixes bug 40419; bugfix + on 0.3.3.2-alpha. + + +Changes in version 0.4.6.5 - 2021-06-14 + Tor 0.4.6.5 is the first stable release in its series. The 0.4.6.x + series includes numerous features and bugfixes, including a significant + improvement to our circuit timeout algorithm that should improve + observed client performance, and a way for relays to report when they are + overloaded. + + This release also includes security fixes for several security issues, + including a denial-of-service attack against onion service clients, + and another denial-of-service attack against relays. Everybody should + upgrade to one of 0.3.5.15, 0.4.4.9, 0.4.5.9, or 0.4.6.5. + + Below are the changes since 0.4.5.8. For a list of changes since + 0.4.6.4-rc, see the ChangeLog file. + + o Major bugfixes (security): + - Don't allow relays to spoof RELAY_END or RELAY_RESOLVED cell on + half-closed streams. Previously, clients failed to validate which + hop sent these cells: this would allow a relay on a circuit to end + a stream that wasn't actually built with it. Fixes bug 40389; + bugfix on 0.3.5.1-alpha. This issue is also tracked as TROVE-2021- + 003 and CVE-2021-34548. + + o Major bugfixes (security, defense-in-depth): + - Detect more failure conditions from the OpenSSL RNG code. + Previously, we would detect errors from a missing RNG + implementation, but not failures from the RNG code itself. + Fortunately, it appears those failures do not happen in practice + when Tor is using OpenSSL's default RNG implementation. Fixes bug + 40390; bugfix on 0.2.8.1-alpha. This issue is also tracked as + TROVE-2021-004. Reported by Jann Horn at Google's Project Zero. + + o Major bugfixes (security, denial of service): + - Resist a hashtable-based CPU denial-of-service attack against + relays. Previously we used a naive unkeyed hash function to look + up circuits in a circuitmux object. An attacker could exploit this + to construct circuits with chosen circuit IDs, to create + collisions and make the hash table inefficient. Now we use a + SipHash construction here instead. Fixes bug 40391; bugfix on + 0.2.4.4-alpha. This issue is also tracked as TROVE-2021-005 and + CVE-2021-34549. Reported by Jann Horn from Google's Project Zero. + - Fix an out-of-bounds memory access in v3 onion service descriptor + parsing. An attacker could exploit this bug by crafting an onion + service descriptor that would crash any client that tried to visit + it. Fixes bug 40392; bugfix on 0.3.0.1-alpha. This issue is also + tracked as TROVE-2021-006 and CVE-2021-34550. Reported by Sergei + Glazunov from Google's Project Zero. + + o Major features (control port, onion services): + - Add controller support for creating version 3 onion services with + client authorization. Previously, only v2 onion services could be + created with client authorization. Closes ticket 40084. Patch by + Neel Chauhan. + + o Major features (directory authority): + - When voting on a relay with a Sybil-like appearance, add the Sybil + flag when clearing out the other flags. This lets a relay operator + know why their relay hasn't been included in the consensus. Closes + ticket 40255. Patch by Neel Chauhan. + + o Major features (metrics): + - Relays now report how overloaded they are in their extrainfo + documents. This information is controlled with the + OverloadStatistics torrc option, and it will be used to improve + decisions about the network's load balancing. Implements proposal + 328; closes ticket 40222. + + o Major features (relay, denial of service): + - Add a new DoS subsystem feature to control the rate of client + connections for relays. Closes ticket 40253. + + o Major features (statistics): + - Relays now publish statistics about the number of v3 onion + services and volume of v3 onion service traffic, in the same + manner they already do for v2 onions. Closes ticket 23126. + + o Major bugfixes (circuit build timeout): + - Improve the accuracy of our circuit build timeout calculation for + 60%, 70%, and 80% build rates for various guard choices. We now + use a maximum likelihood estimator for Pareto parameters of the + circuit build time distribution, instead of a "right-censored + estimator". This causes clients to ignore circuits that never + finish building in their timeout calculations. Previously, clients + were counting such unfinished circuits as having the highest + possible build time value, when in reality these circuits most + likely just contain relays that are offline. We also now wait a + bit longer to let circuits complete for measurement purposes, + lower the minimum possible effective timeout from 1.5 seconds to + 10ms, and increase the resolution of the circuit build time + histogram from 50ms bin widths to 10ms bin widths. Additionally, + we alter our estimate Xm by taking the maximum of the top 10 most + common build time values of the 10ms histogram, and compute Xm as + the average of these. Fixes bug 40168; bugfix on 0.2.2.14-alpha. + - Remove max_time calculation and associated warning from circuit + build timeout 'alpha' parameter estimation, as this is no longer + needed by our new estimator from 40168. Fixes bug 34088; bugfix + on 0.2.2.9-alpha. + + o Major bugfixes (signing key): + - In the tor-gencert utility, give an informative error message if + the passphrase given in `--create-identity-key` is too short. + Fixes bug 40189; bugfix on 0.2.0.1-alpha. Patch by Neel Chauhan. + + o Minor features (bridge): + - We now announce the URL to Tor's new bridge status at + https://bridges.torproject.org/ when Tor is configured to run as a + bridge relay. Closes ticket 30477. + + o Minor features (build system): + - New "make lsp" command to auto generate the compile_commands.json + file used by the ccls server. The "bear" program is needed for + this. Closes ticket 40227. + + o Minor features (client): + - Clients now check whether their streams are attempting to re-enter + the Tor network (i.e. to send Tor traffic over Tor), and close + them preemptively if they think exit relays will refuse them for + this reason. See ticket 2667 for details. Closes ticket 40271. + + o Minor features (command line): + - Add long format name "--torrc-file" equivalent to the existing + command-line option "-f". Closes ticket 40324. Patch by + Daniel Pinto. + + o Minor features (command-line interface): + - Add build informations to `tor --version` in order to ease + reproducible builds. Closes ticket 32102. + - When parsing command-line flags that take an optional argument, + treat the argument as absent if it would start with a '-' + character. Arguments in that form are not intelligible for any of + our optional-argument flags. Closes ticket 40223. + - Allow a relay operator to list the ed25519 keys on the command + line by adding the `rsa` and `ed25519` arguments to the + --list-fingerprint flag to show the respective RSA and ed25519 + relay fingerprint. Closes ticket 33632. Patch by Neel Chauhan. + + o Minor features (compatibility): + - Remove an assertion function related to TLS renegotiation. It was + used nowhere outside the unit tests, and it was breaking + compilation with recent alpha releases of OpenSSL 3.0.0. Closes + ticket 40399. + + o Minor features (control port, stream handling): + - Add the stream ID to the event line in the ADDRMAP control event. + Closes ticket 40249. Patch by Neel Chauhan. + + o Minor features (dormant mode): + - Add a new 'DormantTimeoutEnabled' option to allow coarse-grained + control over whether the client ever becomes dormant from + inactivity. Most people won't need this. Closes ticket 40228. + - Add a new 'DormantTimeoutEnabled' option for coarse-grained + control over whether the client can become dormant from + inactivity. Most people won't need this. Closes ticket 40228. + + o Minor features (geoip data): + - Update the geoip files to match the IPFire Location Database, as + retrieved on 2021/06/10. + + o Minor features (logging): + - Edit heartbeat log messages so that more of them begin with the + string "Heartbeat: ". Closes ticket 40322; patch + from 'cypherpunks'. + - Change the DoS subsystem heartbeat line format to be more clear on + what has been detected/rejected, and which option is disabled (if + any). Closes ticket 40308. + - In src/core/mainloop/mainloop.c and src/core/mainloop/connection.c, + put brackets around IPv6 addresses in log messages. Closes ticket + 40232. Patch by Neel Chauhan. + + o Minor features (logging, diagnostic): + - Log decompression failures at a higher severity level, since they + can help provide missing context for other warning messages. We + rate-limit these messages, to avoid flooding the logs if they + begin to occur frequently. Closes ticket 40175. + + o Minor features (onion services): + - Add a warning message when trying to connect to (no longer + supported) v2 onion services. Closes ticket 40373. + + o Minor features (performance, windows): + - Use SRWLocks to implement locking on Windows. Replaces the + "critical section" locking implementation with the faster + SRWLocks, available since Windows Vista. Closes ticket 17927. + Patch by Daniel Pinto. + + o Minor features (protocol, proxy support, defense in depth): + - Close HAProxy connections if they somehow manage to send us data + before we start reading. Closes another case of ticket 40017. + + o Minor features (tests, portability): + - Port the hs_build_address.py test script to work with recent + versions of python. Closes ticket 40213. Patch from + Samanta Navarro. + + o Minor features (vote document): + - Add a "stats" line to directory authority votes, to report various + statistics that authorities compute about the relays. This will + help us diagnose the network better. Closes ticket 40314. + + o Minor bugfixes (build): + - The configure script now shows whether or not lzma and zstd have + been used, not just if the enable flag was passed in. Fixes bug + 40236; bugfix on 0.4.3.1-alpha. + + o Minor bugfixes (compatibility): + - Fix a failure in the test cases when running on the "hppa" + architecture, along with a related test that might fail on other + architectures in the future. Fixes bug 40274; bugfix + on 0.2.5.1-alpha. + + o Minor bugfixes (compilation): + - Fix a compilation warning about unused functions when building + with a libc that lacks the GLOB_ALTDIRFUNC constant. Fixes bug + 40354; bugfix on 0.4.5.1-alpha. Patch by Daniel Pinto. + + o Minor bugfixes (consensus handling): + - Avoid a set of bugs that could be caused by inconsistently + preferring an out-of-date consensus stored in a stale directory + cache over a more recent one stored on disk as the latest + consensus. Fixes bug 40375; bugfix on 0.3.1.1-alpha. + + o Minor bugfixes (control, sandbox): + - Allow the control command SAVECONF to succeed when the seccomp + sandbox is enabled, and make SAVECONF keep only one backup file to + simplify implementation. Previously SAVECONF allowed a large + number of backup files, which made it incompatible with the + sandbox. Fixes bug 40317; bugfix on 0.2.5.4-alpha. Patch by + Daniel Pinto. + + o Minor bugfixes (directory authorities, voting): + - Add a new consensus method (31) to support any future changes that + authorities decide to make to the value of bwweightscale or + maxunmeasuredbw. Previously, there was a bug that prevented the + authorities from parsing these consensus parameters correctly under + most circumstances. Fixes bug 19011; bugfix on 0.2.2.10-alpha. + + o Minor bugfixes (ipv6): + - Allow non-SOCKSPorts to disable IPv4, IPv6, and PreferIPv4. Some + rare configurations might break, but in this case you can disable + NoIPv4Traffic and NoIPv6Traffic as needed. Fixes bug 33607; bugfix + on 0.4.1.1-alpha. Patch by Neel Chauhan. + + o Minor bugfixes (key generation): + - Do not require a valid torrc when using the `--keygen` argument to + generate a signing key. This allows us to generate keys on systems + or users which may not run Tor. Fixes bug 40235; bugfix on + 0.2.7.2-alpha. Patch by Neel Chauhan. + + o Minor bugfixes (logging, relay): + - Emit a warning if an Address is found to be internal and tor can't + use it. Fixes bug 40290; bugfix on 0.4.5.1-alpha. + + o Minor bugfixes (metrics port): + - Fix a bug that made tor try to re-bind() on an already open + MetricsPort every 60 seconds. Fixes bug 40370; bugfix + on 0.4.5.1-alpha. + + o Minor bugfixes (onion services, logging): + - Downgrade the severity of a few rendezvous circuit-related + warnings from warning to info. Fixes bug 40207; bugfix on + 0.3.2.1-alpha. Patch by Neel Chauhan. + + o Minor bugfixes (relay): + - Reduce the compression level for data streaming from HIGH to LOW. + This should reduce the CPU and memory burden for directory caches. + Fixes bug 40301; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (testing, BSD): + - Fix pattern-matching errors when patterns expand to invalid paths + on BSD systems. Fixes bug 40318; bugfix on 0.4.5.1-alpha. Patch by + Daniel Pinto. + + o Code simplification and refactoring: + - Remove the orconn_ext_or_id_map structure and related functions. + (Nothing outside of unit tests used them.) Closes ticket 33383. + Patch by Neel Chauhan. + + o Removed features: + - Remove unneeded code for parsing private keys in directory + documents. This code was only used for client authentication in v2 + onion services, which are now unsupported. Closes ticket 40374. + - As of this release, Tor no longer supports the old v2 onion + services. They were deprecated last July for security, and support + will be removed entirely later this year. We strongly encourage + everybody to migrate to v3 onion services. For more information, + see https://blog.torproject.org/v2-deprecation-timeline . Closes + ticket 40266. (NOTE: We accidentally released an earlier version + of the 0.4.6.1-alpha changelog without this entry. Sorry for + the confusion!) + + o Code simplification and refactoring (metrics, DoS): + - Move the DoS subsystem into the subsys manager, including its + configuration options. Closes ticket 40261. + + o Documentation (manual): + - Move the ServerTransport* options to the "SERVER OPTIONS" section. + Closes issue 40331. + - Indicate that the HiddenServiceStatistics option also applies to + bridges. Closes ticket 40346. + - Move the description of BridgeRecordUsageByCountry to the section + "STATISTICS OPTIONS". Closes ticket 40323. + + o Removed features (relay): + - Because DirPorts are only used on authorities, relays no longer + advertise them. Similarly, self-testing for DirPorts has been + disabled, since an unreachable DirPort is no reason for a relay + not to advertise itself. (Configuring a DirPort will still work, + for now.) Closes ticket 40282. + + +Changes in version 0.4.5.8 - 2021-05-10 + Tor 0.4.5.8 fixes several bugs in earlier version, backporting fixes + from the 0.4.6.x series. + + o Minor features (compatibility, Linux seccomp sandbox, backport from 0.4.6.3-rc): + - Add a workaround to enable the Linux sandbox to work correctly + with Glibc 2.33. This version of Glibc has started using the + fstatat() system call, which previously our sandbox did not allow. + Closes ticket 40382; see the ticket for a discussion of trade-offs. + + o Minor features (compilation, backport from 0.4.6.3-rc): + - Make the autoconf script build correctly with autoconf versions + 2.70 and later. Closes part of ticket 40335. + + o Minor features (fallback directory list, backport from 0.4.6.2-alpha): + - Regenerate the list of fallback directories to contain a new set + of 200 relays. Closes ticket 40265. + + o Minor features (geoip data): + - Update the geoip files to match the IPFire Location Database, as + retrieved on 2021/05/07. + + o Minor features (onion services): + - Add warning message when connecting to now deprecated v2 onion + services. As announced, Tor 0.4.5.x is the last series that will + support v2 onions. Closes ticket 40373. + + o Minor bugfixes (bridge, pluggable transport, backport from 0.4.6.2-alpha): + - Fix a regression that made it impossible start Tor using a bridge + line with a transport name and no fingerprint. Fixes bug 40360; + bugfix on 0.4.5.4-rc. + + o Minor bugfixes (build, cross-compilation, backport from 0.4.6.3-rc): + - Allow a custom "ar" for cross-compilation. Our previous build + script had used the $AR environment variable in most places, but + it missed one. Fixes bug 40369; bugfix on 0.4.5.1-alpha. + + o Minor bugfixes (channel, DoS, backport from 0.4.6.2-alpha): + - Fix a non-fatal BUG() message due to a too-early free of a string, + when listing a client connection from the DoS defenses subsystem. + Fixes bug 40345; bugfix on 0.4.3.4-rc. + + o Minor bugfixes (compiler warnings, backport from 0.4.6.3-rc): + - Fix an indentation problem that led to a warning from GCC 11.1.1. + Fixes bug 40380; bugfix on 0.3.0.1-alpha. + + o Minor bugfixes (controller, backport from 0.4.6.1-alpha): + - Fix a "BUG" warning that would appear when a controller chooses + the first hop for a circuit, and that circuit completes. Fixes bug + 40285; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (onion service, client, memory leak, backport from 0.4.6.3-rc): + - Fix a bug where an expired cached descriptor could get overwritten + with a new one without freeing it, leading to a memory leak. Fixes + bug 40356; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (testing, BSD, backport from 0.4.6.2-alpha): + - Fix pattern-matching errors when patterns expand to invalid paths + on BSD systems. Fixes bug 40318; bugfix on 0.4.5.1-alpha.
