+Changes in version 0.4.4.5 - 2020-09-15
+ Tor 0.4.4.5 is the first stable release in the 0.4.4.x series. This
+ series improves our guard selection algorithms, adds v3 onion balance
+ support, improves the amount of code that can be disabled when running
+ without relay support, and includes numerous small bugfixes and
+ enhancements. It also lays the ground for some IPv6 features that
+ we'll be developing more in the next (0.4.5) series.
+
+ Per our support policy, we support each stable release series for nine
+ months after its first stable release, or three months after the first
+ stable release of the next series: whichever is longer. This means
+ that 0.4.4.x will be supported until around June 2021--or later, if
+ 0.4.5.x is later than anticipated.
+
+ Note also that support for 0.4.2.x has just ended; support for 0.4.3
+ will continue until Feb 15, 2021. We still plan to continue supporting
+ 0.3.5.x, our long-term stable series, until Feb 2022.
+
+ Below are the changes since 0.4.4.4-rc. For a complete list of changes
+ since 0.4.3.6, see the ReleaseNotes file.
+
+ o Major bugfixes (onion services, DoS):
+ - Correct handling of parameters for the onion service DoS defense.
+ Previously, the consensus parameters for the onion service DoS
+ defenses were overwriting the parameters set by the service
+ operator using HiddenServiceEnableIntroDoSDefense. Fixes bug
+ 40109; bugfix on 0.4.2.1-alpha.
+
+ o Major bugfixes (stats, onion services):
+ - Fix a bug where we were undercounting the Tor network's total
+ onion service traffic, by ignoring any traffic originating from
+ clients. Now we count traffic from both clients and services.
+ Fixes bug 40117; bugfix on 0.2.6.2-alpha.
+
+ o Minor features (control port):
+ - If a ClientName was specified in ONION_CLIENT_AUTH_ADD for an
+ onion service, display it when we use ONION_CLIENT_AUTH_VIEW.
+ Closes ticket 40089. Patch by Neel Chauhan.
+
+ o Minor features (denial-of-service memory limiter):
+ - Allow the user to configure even lower values for the
+ MaxMemInQueues parameter. Relays now enforce a minimum of 64 MB,
+ when previously the minimum was 256 MB. On clients, there is no
+ minimum. Relays and clients will both warn if the value is set so
+ low that Tor is likely to stop working. Closes ticket 24308.
+
+ o Minor features (tests):
+ - Our "make check" target now runs the unit tests in 8 parallel
+ chunks. Doing this speeds up hardened CI builds by more than a
+ factor of two. Closes ticket 40098.
+
+ o Minor bugfixes (guard selection algorithm):
+ - Avoid needless guard-related warning when upgrading from 0.4.3 to
+ 0.4.4. Fixes bug 40105; bugfix on 0.4.4.1-alpha.
+
+ o Minor bugfixes (tests):
+ - Fix the behavior of the rend_cache/clean_v2_descs_as_dir when run
+ on its own. Previously, it would exit with an error. Fixes bug
+ 40099; bugfix on 0.2.8.1-alpha.

+Changes in version 0.4.4.5 - 2020-09-15
+ Tor 0.4.4.5 is the first stable release in the 0.4.4.x series. This

+ support, improves the amount of code that can be disabled when running
+ without relay support, and includes numerous small bugfixes and

+ that 0.4.4.x will be supported until around June 2021--or later, if

+
+ Below are the changes since 0.4.3.6-rc. For a complete list of changes
+ since 0.4.4.4-rc, see the ChangeLog file.
+
+ o Major features (Proposal 310, performance + security):
+ - Implements Proposal 310, "Bandaid on guard selection". Proposal
+ 310 solves load-balancing issues with older versions of the guard
+ selection algorithm, and improves its security. Under this new
+ algorithm, a newly selected guard never becomes Primary unless all
+ previously sampled guards are unreachable. Implements
+ recommendation from 32088. (Proposal 310 is linked to the CLAPS
+ project researching optimal client location-aware path selections.
+ This project is a collaboration between the UCLouvain Crypto Group,
+ the U.S. Naval Research Laboratory, and Princeton University.)
+
+ o Major features (fallback directory list):
+ - Replace the 148 fallback directories originally included in Tor
+ 0.4.1.4-rc (of which around 105 are still functional) with a list
+ of 144 fallbacks generated in July 2020. Closes ticket 40061.
+
+ o Major features (IPv6, relay):
+ - Consider IPv6-only EXTEND2 cells valid on relays. Log a protocol
+ warning if the IPv4 or IPv6 address is an internal address, and
+ internal addresses are not allowed. But continue to use the other
+ address, if it is valid. Closes ticket 33817.
+ - If a relay can extend over IPv4 and IPv6, and both addresses are
+ provided, it chooses between them uniformly at random. Closes
+ ticket 33817.
+ - Re-use existing IPv6 connections for circuit extends. Closes
+ ticket 33817.
+ - Relays may extend circuits over IPv6, if the relay has an IPv6
+ ORPort, and the client supplies the other relay's IPv6 ORPort in
+ the EXTEND2 cell. IPv6 extends will be used by the relay IPv6
+ ORPort self-tests in 33222. Closes ticket 33817.
+
+ o Major features (v3 onion services):
+ - Allow v3 onion services to act as OnionBalance backend instances,
+ by using the HiddenServiceOnionBalanceInstance torrc option.
+ Closes ticket 32709.
+
+ o Major bugfixes (NSS):
+ - When running with NSS enabled, make sure that NSS knows to expect
+ nonblocking sockets. Previously, we set our TCP sockets as
+ nonblocking, but did not tell NSS, which in turn could lead to
+ unexpected blocking behavior. Fixes bug 40035; bugfix
+ on 0.3.5.1-alpha.
+
+ o Major bugfixes (onion services, DoS):
+ - Correct handling of parameters for the onion service DoS defense.
+ Previously, the consensus parameters for the onion service DoS
+ defenses were overwriting the parameters set by the service
+ operator using HiddenServiceEnableIntroDoSDefense. Fixes bug
+ 40109; bugfix on 0.4.2.1-alpha.
+
+ o Major bugfixes (stats, onion services):
+ - Fix a bug where we were undercounting the Tor network's total
+ onion service traffic, by ignoring any traffic originating from
+ clients. Now we count traffic from both clients and services.
+ Fixes bug 40117; bugfix on 0.2.6.2-alpha.
+
+ o Minor features (security):
+ - Channels using obsolete versions of the Tor link protocol are no
+ longer allowed to circumvent address-canonicity checks. (This is
+ only a minor issue, since such channels have no way to set ed25519
+ keys, and therefore should always be rejected for circuits that
+ specify ed25519 identities.) Closes ticket 40081.
+
+ o Minor features (bootstrap reporting):
+ - Report more detailed reasons for bootstrap failure when the
+ failure happens due to a TLS error. Previously we would just call
+ these errors "MISC" when they happened during read, and "DONE"
+ when they happened during any other TLS operation. Closes
+ ticket 32622.
+
+ o Minor features (client-only compilation):
+ - Disable more code related to the ext_orport protocol when
+ compiling without support for relay mode. Closes ticket 33368.
+ - Disable more of our self-testing code when support for relay mode
+ is disabled. Closes ticket 33370.
+ - Most server-side DNS code is now disabled when building without
+ support for relay mode. Closes ticket 33366.
+
+ o Minor features (code safety):
+ - Check for failures of tor_inet_ntop() and tor_inet_ntoa()
+ functions in DNS and IP address processing code, and adjust
+ codepaths to make them less likely to crash entire Tor instances.
+ Resolves issue 33788.
+
+ o Minor features (continuous integration):
+ - Run unit-test and integration test (Stem, Chutney) jobs with
+ ALL_BUGS_ARE_FATAL macro being enabled on Travis and Appveyor.
+ Resolves ticket 32143.
+
+ o Minor features (control port):
+ - If a ClientName was specified in ONION_CLIENT_AUTH_ADD for an
+ onion service, display it when we use ONION_CLIENT_AUTH_VIEW.
+ Closes ticket 40089. Patch by Neel Chauhan.
+ - Return a descriptive error message from the 'GETINFO status/fresh-
+ relay-descs' command on the control port. Previously, we returned
+ a generic error of "Error generating descriptor". Closes ticket
+ 32873. Patch by Neel Chauhan.
+
+ o Minor features (defense in depth):
+ - Wipe more data from connection address fields before returning
+ them to the memory heap. Closes ticket 6198.
+
+ o Minor features (denial-of-service memory limiter):
+ - Allow the user to configure even lower values for the
+ MaxMemInQueues parameter. Relays now enforce a minimum of 64 MB,
+ when previously the minimum was 256 MB. On clients, there is no
+ minimum. Relays and clients will both warn if the value is set so
+ low that Tor is likely to stop working. Closes ticket 24308.
+
+ o Minor features (developer tooling):
+ - Add a script to help check the alphabetical ordering of option
+ names in the manual page. Closes ticket 33339.
+ - Refrain from listing all .a files that are generated by the Tor
+ build in .gitignore. Add a single wildcard *.a entry that covers
+ all of them for present and future. Closes ticket 33642.
+ - Add a script ("git-install-tools.sh") to install git hooks and
+ helper scripts. Closes ticket 33451.
+
+ o Minor features (directory authority):
+ - Authorities now recommend the protocol versions that are supported
+ by Tor 0.3.5 and later. (Earlier versions of Tor have been
+ deprecated since January of this year.) This recommendation will
+ cause older clients and relays to give a warning on startup, or
+ when they download a consensus directory. Closes ticket 32696.
+
+ o Minor features (directory authority, shared random):
+ - Refactor more authority-only parts of the shared-random scheduling
+ code to reside in the dirauth module, and to be disabled when
+ compiling with --disable-module-dirauth. Closes ticket 33436.
+
+ o Minor features (directory):
+ - Remember the number of bytes we have downloaded for each directory
+ purpose while bootstrapping, and while fully bootstrapped. Log
+ this information as part of the heartbeat message. Closes
+ ticket 32720.
+
+ o Minor features (entry guards):
+ - Reinstate support for GUARD NEW/UP/DOWN control port events.
+ Closes ticket 40001.
+
+ o Minor features (IPv6 support):
+ - Adds IPv6 support to tor_addr_is_valid(). Adds tests for the above
+ changes and tor_addr_is_null(). Closes ticket 33679. Patch
+ by MrSquanchee.
+ - Allow clients and relays to send dual-stack and IPv6-only EXTEND2
+ cells. Parse dual-stack and IPv6-only EXTEND2 cells on relays.
+ Closes ticket 33901.
+
+ o Minor features (linux seccomp2 sandbox, portability):
+ - Allow Tor to build on platforms where it doesn't know how to
+ report which syscall caused the linux seccomp2 sandbox to fail.
+ This change should make the sandbox code more portable to less
+ common Linux architectures. Closes ticket 34382.
+ - Permit the unlinkat() syscall, which some Libc implementations use
+ to implement unlink(). Closes ticket 33346.
+
+ o Minor features (logging):
+ - When trying to find our own address, add debug-level logging to
+ report the sources of candidate addresses. Closes ticket 32888.
+
+ o Minor features (onion service client, SOCKS5):
+ - Add 3 new SocksPort ExtendedErrors (F2, F3, F7) that reports back
+ new type of onion service connection failures. The semantics of
+ these error codes are documented in proposal 309. Closes
+ ticket 32542.
+
+ o Minor features (onion service v3):
+ - If a service cannot upload its descriptor(s), log why at INFO
+ level. Closes ticket 33400; bugfix on 0.3.2.1-alpha.
+
+ o Minor features (python scripts):
+ - Stop assuming that /usr/bin/python exists. Instead of using a
+ hardcoded path in scripts that still use Python 2, use
+ /usr/bin/env, similarly to the scripts that use Python 3. Fixes
+ bug 33192; bugfix on 0.4.2.
+
+ o Minor features (testing, architecture):
+ - Our test scripts now double-check that subsystem initialization
+ order is consistent with the inter-module dependencies established
+ by our .may_include files. Implements ticket 31634.
+ - Initialize all subsystems at the beginning of our unit test
+ harness, to avoid crashes due to uninitialized subsystems. Follow-
+ up from ticket 33316.
+ - Our "make check" target now runs the unit tests in 8 parallel
+ chunks. Doing this speeds up hardened CI builds by more than a
+ factor of two. Closes ticket 40098.
+
+ o Minor features (v3 onion services):
+ - Add v3 onion service status to the dumpstats() call which is
+ triggered by a SIGUSR1 signal. Previously, we only did v2 onion
+ services. Closes ticket 24844. Patch by Neel Chauhan.
+
+ o Minor features (windows):
+ - Add support for console control signals like Ctrl+C in Windows.
+ Closes ticket 34211. Patch from Damon Harris (TheDcoder).
+
+ o Minor bugfixes (control port, onion service):
+ - Consistently use 'address' in "Invalid v3 address" response to
+ ONION_CLIENT_AUTH commands. Previously, we would sometimes say
+ 'addr'. Fixes bug 40005; bugfix on 0.4.3.1-alpha.
+
+ o Minor bugfixes (correctness, buffers):
+ - Fix a correctness bug that could cause an assertion failure if we
+ ever tried using the buf_move_all() function with an empty input
+ buffer. As far as we know, no released versions of Tor do this.
+ Fixes bug 40076; bugfix on 0.3.3.1-alpha.
+
+ o Minor bugfixes (directory authorities):
+ - Directory authorities now reject votes that arrive too late. In
+ particular, once an authority has started fetching missing votes,
+ it no longer accepts new votes posted by other authorities. This
+ change helps prevent a consensus split, where only some authorities
+ have the late vote. Fixes bug 4631; bugfix on 0.2.0.5-alpha.
+
+ o Minor bugfixes (git scripts):
+ - Stop executing the checked-out pre-commit hook from the pre-push
+ hook. Instead, execute the copy in the user's git directory. Fixes
+ bug 33284; bugfix on 0.4.1.1-alpha.
+
+ o Minor bugfixes (initialization):
+ - Initialize the subsystems in our code in an order more closely
+ corresponding to their dependencies, so that every system is
+ initialized before the ones that (theoretically) depend on it.
+ Fixes bug 33316; bugfix on 0.4.0.1-alpha.
+
+ o Minor bugfixes (IPv4, relay):
+ - Check for invalid zero IPv4 addresses and ports when sending and
+ receiving extend cells. Fixes bug 33900; bugfix on 0.2.4.8-alpha.
+
+ o Minor bugfixes (IPv6, relay):
+ - Consider IPv6 addresses when checking if a connection is
+ canonical. In 17604, relays assumed that a remote relay could
+ consider an IPv6 connection canonical, but did not set the
+ canonical flag on their side of the connection. Fixes bug 33899;
+ bugfix on 0.3.1.1-alpha.
+ - Log IPv6 addresses on connections where this relay is the
+ responder. Previously, responding relays would replace the remote
+ IPv6 address with the IPv4 address from the consensus. Fixes bug
+ 33899; bugfix on 0.3.1.1-alpha.
+
+ o Minor bugfixes (linux seccomp2 sandbox):
+ - Fix a regression on sandboxing rules for the openat() syscall. The
+ fix for bug 25440 fixed the problem on systems with glibc >= 2.27
+ but broke with versions of glibc. We now choose a rule based on
+ the glibc version. Patch from Daniel Pinto. Fixes bug 27315;
+ bugfix on 0.3.5.11.
+ - Makes the seccomp sandbox allow the correct syscall for opendir
+ according to the running glibc version. This fixes crashes when
+ reloading torrc with sandbox enabled when running on glibc 2.15 to
+ 2.21 and 2.26. Patch from Daniel Pinto. Fixes bug 40020; bugfix
+ on 0.3.5.11.
+
+ o Minor bugfixes (logging, testing):
+ - Make all of tor's assertion macros support the ALL_BUGS_ARE_FATAL
+ and DISABLE_ASSERTS_IN_UNIT_TESTS debugging modes. (IF_BUG_ONCE()
+ used to log a non-fatal warning, regardless of the debugging
+ mode.) Fixes bug 33917; bugfix on 0.2.9.1-alpha.
+ - Remove surprising empty line in the INFO-level log about circuit
+ build timeout. Fixes bug 33531; bugfix on 0.3.3.1-alpha.
+
+ o Minor bugfixes (mainloop):
+ - Better guard against growing a buffer past its maximum 2GB in
+ size. Fixes bug 33131; bugfix on 0.3.0.4-rc.
+
+ o Minor bugfixes (onion service v3 client):
+ - Remove a BUG() warning that could occur naturally. Fixes bug
+ 34087; bugfix on 0.3.2.1-alpha.
+
+ o Minor bugfixes (onion service, logging):
+ - Fix a typo in a log message PublishHidServDescriptors is set to 0.
+ Fixes bug 33779; bugfix on 0.3.2.1-alpha.
+
+ o Minor bugfixes (onion services v3):
+ - Avoid a non-fatal assertion failure in certain edge-cases when
+ opening an intro circuit as a client. Fixes bug 34084; bugfix
+ on 0.3.2.1-alpha.
+
+ o Minor bugfixes (protocol versions):
+ - Sort tor's supported protocol version lists, as recommended by the
+ tor directory specification. Fixes bug 33285; bugfix
+ on 0.4.0.1-alpha.
+
+ o Minor bugfixes (rate limiting, bridges, pluggable transports):
+ - On a bridge, treat all connections from an ExtORPort as remote by
+ default for the purposes of rate-limiting. Previously, bridges
+ would treat the connection as local unless they explicitly
+ received a "USERADDR" command. ExtORPort connections still count
+ as local if there is a USERADDR command with an explicit local
+ address. Fixes bug 33747; bugfix on 0.2.5.1-alpha.
+
+ o Minor bugfixes (refactoring):
+ - Lift circuit_build_times_disabled() out of the
+ circuit_expire_building() loop, to save CPU time when there are
+ many circuits open. Fixes bug 33977; bugfix on 0.3.5.9.
+
+ o Minor bugfixes (relay, self-testing):
+ - When starting up as a relay, if we haven't been able to verify
+ that we're reachable, only launch reachability tests at most once
+ a minute. Previously, we had been launching tests up to once a
+ second, which was needlessly noisy. Fixes bug 40083; bugfix
+ on 0.2.8.1-alpha.
+
+ o Minor bugfixes (relay, usability):
+ - Adjust the rules for when to warn about having too many
+ connections to other relays. Previously we'd tolerate up to 1.5
+ connections per relay on average. Now we tolerate more connections
+ for directory authorities, and raise the number of total
+ connections we need to see before we warn. Fixes bug 33880; bugfix
+ on 0.3.1.1-alpha.
+
+ o Minor bugfixes (SOCKS, onion service client):
+ - Detect v3 onion service addresses of the wrong length when
+ returning the F6 ExtendedErrors code. Fixes bug 33873; bugfix
+ on 0.4.3.1-alpha.
+
+ o Minor bugfixes (tests):
+ - Fix the behavior of the rend_cache/clean_v2_descs_as_dir when run
+ on its own. Previously, it would exit with an error. Fixes bug
+ 40099; bugfix on 0.2.8.1-alpha.
+
+ o Minor bugfixes (v3 onion services):
+ - Remove a BUG() warning that could trigger in certain unlikely
+ edge-cases. Fixes bug 34086; bugfix on 0.3.2.1-alpha.
+ - Remove a BUG() that was causing a stacktrace when a descriptor
+ changed at an unexpected time. Fixes bug 28992; bugfix
+ on 0.3.2.1-alpha.
+
+ o Minor bugfixes (windows):
+ - Fix a bug that prevented Tor from starting if its log file grew
+ above 2GB. Fixes bug 31036; bugfix on 0.2.1.8-alpha.
+
+ o Code simplification and refactoring:
+ - Define and use a new constant TOR_ADDRPORT_BUF_LEN which is like
+ TOR_ADDR_BUF_LEN but includes enough space for an IP address,
+ brackets, separating colon, and port number. Closes ticket 33956.
+ Patch by Neel Chauhan.
+ - Merge the orconn and ocirc events into the "core" subsystem, which
+ manages or connections and origin circuits. Previously they were
+ isolated in subsystems of their own.
+ - Move LOG_PROTOCOL_WARN to app/config. Resolves a dependency
+ inversion. Closes ticket 33633.
+ - Move the circuit extend code to the relay module. Split the
+ circuit extend function into smaller functions. Closes
+ ticket 33633.
+ - Rewrite port_parse_config() to use the default port flags from
+ port_cfg_new(). Closes ticket 32994. Patch by MrSquanchee.
+ - Updated comments in 'scheduler.c' to reflect old code changes, and
+ simplified the scheduler channel state change code. Closes
+ ticket 33349.
+ - Refactor configuration parsing to use the new config subsystem
+ code. Closes ticket 33014.
+ - Move a series of functions related to address resolving into their
+ own files. Closes ticket 33789.
+
+ o Documentation:
+ - Replace most http:// URLs in our code and documentation with
+ https:// URLs. (We have left unchanged the code in src/ext/, and
+ the text in LICENSE.) Closes ticket 31812. Patch from Jeremy Rand.
+ - Document the limitations of using %include on config files with
+ seccomp sandbox enabled. Fixes documentation bug 34133; bugfix on
+ 0.3.1.1-alpha. Patch by Daniel Pinto.
+
+ o Removed features:
+ - Our "check-local" test target no longer tries to use the
+ Coccinelle semantic patching tool parse all the C files. While it
+ is a good idea to try to make sure Coccinelle works on our C
+ before we run a Coccinelle patch, doing so on every test run has
+ proven to be disruptive. You can still run this tool manually with
+ "make check-cocci". Closes ticket 40030.
+ - Remove the ClientAutoIPv6ORPort option. This option attempted to
+ randomly choose between IPv4 and IPv6 for client connections, and
+ wasn't a true implementation of Happy Eyeballs. Often, this option
+ failed on IPv4-only or IPv6-only connections. Closes ticket 32905.
+ Patch by Neel Chauhan.
+ - Stop shipping contrib/dist/rc.subr file, as it is not being used
+ on FreeBSD anymore. Closes issue 31576.
+
+ o Testing:
+ - Add a basic IPv6 test to "make test-network". This test only runs
+ when the local machine has an IPv6 stack. Closes ticket 33300.
+ - Add test-network-ipv4 and test-network-ipv6 jobs to the Makefile.
+ These jobs run the IPv4-only and dual-stack chutney flavours from
+ test-network-all. Closes ticket 33280.
+ - Remove a redundant distcheck job. Closes ticket 33194.
+ - Run the test-network-ipv6 Makefile target in the Travis CI IPv6
+ chutney job. This job runs on macOS, so it's a bit slow. Closes
+ ticket 33303.
+ - Sort the Travis jobs in order of speed. Putting the slowest jobs
+ first takes full advantage of Travis job concurrency. Closes
+ ticket 33194.
+ - Stop allowing the Chutney IPv6 Travis job to fail. This job was
+ previously configured to fast_finish (which requires
+ allow_failure), to speed up the build. Closes ticket 33195.
+ - Test v3 onion services to tor's mixed IPv4 chutney network. And
+ add a mixed IPv6 chutney network. These networks are used in the
+ test-network-all, test-network-ipv4, and test-network-ipv6 make
+ targets. Closes ticket 33334.
+ - Use the "bridges+hs-v23" chutney network flavour in "make test-
+ network". This test requires a recent version of chutney (mid-
+ February 2020). Closes ticket 28208.
+ - When a Travis chutney job fails, use chutney's new "diagnostics.sh"
+ tool to produce detailed diagnostic output. Closes ticket 32792.
+
+ o Deprecated features (onion service v2):
+ - Add a deprecation warning for version 2 onion services. Closes
+ ticket 40003.
+
+ o Documentation (manual page):
+ - Add cross reference links and a table of contents to the HTML tor
+ manual page. Closes ticket 33369. Work by Swati Thacker as part of
+ Google Season of Docs.
+ - Alphabetize the Denial of Service Mitigation Options, Directory
+ Authority Server Options, Hidden Service Options, and Testing
+ Network Options sections of the tor(1) manual page. Closes ticket
+ 33275. Work by Swati Thacker as part of Google Season of Docs.
+ - Refrain from mentioning nicknames in manpage section for MyFamily
+ torrc option. Resolves issue 33417.
+ - Updated the options set by TestingTorNetwork in the manual page.
+ Closes ticket 33778.
