When Tor is dormant, it avoids + network activity and CPU wakeups until it is reawoken either by a + user request or by a controller command. For more information, see + the configuration options starting with "Dormant". Implements + tickets 2149 and 28335. + - The client's memory of whether it is "dormant", and how long it + has spend idle, persists across invocations. Implements + ticket 28624. + - There is a DormantOnFirstStartup option that integrators can use + if they expect that in many cases, Tor will be installed but + not used. + + o Major features (bootstrap): + - Report the first connection to a relay as the earliest phases of + bootstrap progress, regardless of whether it's a connection for + building application circuits. This allows finer-grained reporting + of early progress than previously possible with the improvements + of ticket 27169. Closes tickets 27167 and 27103. Addresses + ticket 27308. + - Separately report the intermediate stage of having connected to a + proxy or pluggable transport, versus succesfully using that proxy + or pluggable transport to connect to a relay. Closes tickets 27100 + and 28884. + + o Major features (circuit padding): + - Implement preliminary support for the circuit padding portion of + Proposal 254. The implementation supports Adaptive Padding (aka + WTF-PAD) state machines for use between experimental clients and + relays. Support is also provided for APE-style state machines that + use probability distributions instead of histograms to specify + inter-packet delay. At the moment, Tor does not provide any + padding state machines that are used in normal operation -- this + feature exists solely for experimentation in this release. Closes + ticket 28142. + + o Major features (refactoring): + - Tor now uses an explicit list of its own subsystems when + initializing and shutting down. Previously, these systems were + managed implicitly though various places throughout the codebase. + (There still some subsystems using the old system.) Closes + ticket 28330. + + o Minor feature (bootstrap): + - When reporting bootstrap progress, stop distinguishing between + situations where it seems that only internal paths are available + and situations where it seems that external paths are available. + Previously, tor would often erroneously report that it had only + internal paths. Closes ticket 27402. + + o Minor features (Continuous Integration): + - Log Python version during each Travis CI job. Resolves + issue 28551. + + o Minor features (controller): + - Add a DROPOWNERSHIP command to undo the effects of TAKEOWNERSHIP. + Implements ticket 28843. + + o Minor features (developer tooling): + - Provide a git hook script to prevent "fixup!" and "squash!" + commits from ending up in master. Closes ticket 27993. + + o Minor features (directory authority): + - Directory authorities support a new consensus algorithm, under + which microdescriptor entries are encoded in a canonical form. + This improves their compressibility in transit and on the client. + Closes ticket 28266; implements proposal 298. + + o Minor features (directory authority, relay): + - Authorities now vote on a "StaleDesc" flag to indicate that a + relay's descriptor is so old that the relay should upload again + soon. Relays understand this flag, and treat it as a signal to + upload a new descriptor. This flag will eventually let us remove + the 'published' date from routerstatus entries, and save a great + deal of space in our consensus diffs. Closes ticket 26770; + implements proposal 293. + + o Minor features (fallback directory mirrors): + - Update the fallback whitelist based on operator opt-ins and opt- + outs. Closes ticket 24805, patch by Phoul. + - Accept fallbacks that deliver reasonably live consensuses. + (Consensuses that will become valid less than 24 hours in the + future, or that expired less than 24 hours ago.) Closes + ticket 28768. + - Accept relays that are a fuzzy match to a fallback whitelist + entry. If a relay matches at least one fingerprint, IPv4 address, + or IPv6 address in the fallback whitelist, it can become a + fallback. This reduces the work required to keep the list up to + date. Closes ticket 24838. + + o Minor features (FreeBSD): + - Warn relay operators if the "net.inet.ip.random_id" sysctl (IP ID + randomization) is disabled on their relay if it is running on + FreeBSD based operating systems. Closes ticket 28518. + + o Minor features (HTTP standards compliance): + - Don't send Content-Type: application/octet-stream for transparently + compressed documents, which confused browsers. Closes ticket 28100. + + o Minor features (ipv6): + - We add an option ClientAutoIPv6ORPort which makes clients randomly + prefer a node's IPv4 or IPv6 ORPort. The random preference is set + every time a node is loaded from a new consensus or bridge config. + Closes ticket 27490. Patch by Neel Chauhan. + - When using addrs_in_same_network_family(), check IPv6 subnets as + well as IPv4 ones where possible when a client chooses circuit + paths. Previously, we used this function only for IPv4 subnets. + Closes ticket 24393. Patch by Neel Chauhan. + + o Minor features (log messages): + - Improve log message in HSv3 service that could print out negative + revision counters. Closes ticket 27707. Patch by "ffmancera". + + o Minor features (memory usage): + - Store microdescriptor family lists with a more compact + representation to save memory. Closes ticket 27359. + - Tor clients no longer need to keep the full text of a consensus in + memory in order to parse it, or apply a diff to it. Instead, they + use mmap() to read the consensus files from disk. Closes + ticket 27244. + + o Minor features (parsing): + - Directory authorities now validate that router descriptors and + ExtraInfo documents are in a valid subset of UTF-8, and reject + them if not. Closes ticket 27367. + + o Minor features (performance): + - Avoid parsing the same protocol-versions string over and over in + summarize_protover_flags(). This should save us a huge number of + malloc calls on startup, and may reduce memory fragmentation with + some allocators. Closes ticket 27225. + - Remove a needless memset() call from get_token_arguments, thereby + speeding up the tokenization of directory objects by about 20%. + Closes ticket 28852. + - Replace parse_short_policy() with a faster implementation, to + improve microdescriptor parsing time. Closes ticket 28853. + - Speed up directory parsing a little by avoiding use of the non- + inlined strcmp_len() function. Closes ticket 28856. + - Speed up microdesriptor parsing by about 30%, to help improve + startup time. Closes ticket 28839. + + o Minor features (pluggable transports): + - Add support for emitting STATUS updates to Tor's control port from + a pluggable transport process. Closes ticket 28846. + - Add support for logging to Tor's logging subsystem from a + pluggable transport process. Closes ticket 28180 + + o Minor features (process management): + - Add new Process API for handling child processes. This new API + allows Tor to have bi-directional communication with child + processes on both Unix and Windows. Closes ticket 28179. + - Use the subsystem module to initialize and shut down the process + module. Closes ticket 28847. + + o Minor features (relay): + - When listing relay families, list them in canonical form including + the relay's own identity, and try to give a more useful set of + warnings. Part of ticket 28266 and proposal 298. + + o Minor features (required protocols): + - Tor no longer exits if it is missing a required protocol, if the + consensus that requires the protocol predates the release date of + the version of Tor. This change prevents Tor releases from exiting + because of an old cached consensus, on the theory that a newer + cached consensus might not require the protocol. Implements + proposal 297; closes ticket 27735. + + o Minor features (testing): + - Allow HeartbeatPeriod of less than 30 minutes in testing Tor + networks. Closes ticket 28840, patch by robgjansen + + o Minor bugfixes (client, bootstrap): + - When Tor's clock is behind the clocks on the authorities, allow + Tor to bootstrap successfully. Fixes bug 28591; bugfix + on 0.2.0.9-alpha. + + o Minor bugfixes (client, guard selection): + - When Tor's consensus has expired, but is still reasonably live, + use it to select guards. Fixes bug 24661; bugfix on 0.3.0.1-alpha. + + o Minor bugfixes (compilation): + - Fix missing headers required for proper detection of OpenBSD. Fixes + bug 28938; bugfix on 0.3.5.1-alpha. Patch from Kris Katterjohn. + + o Minor bugfixes (directory clients): + - Mark outdated dirservers when Tor only has a reasonably live + consensus. Fixes bug 28569; bugfix on 0.3.2.5-alpha. + + o Minor bugfixes (directory mirror): + - When Tor's clock is behind the clocks on the authorities, allow + Tor to serve future consensuses. Fixes bug 28654; bugfix + on 0.3.0.1-alpha. + + o Minor bugfixes (DNS): + - Gracefully handle empty or absent resolve.conf file by falling + back to using localhost DNS service and hoping it works. Fixes bug + 21900; bugfix on 0.2.1.10-alpha. + + o Minor bugfixes (fallback scripts): + - In updateFallbackDirs.py, call the filter file a "fallback list" + instead of a "whitelist" in check_existing mode. Fixes bug 24953; + bugfix on 0.3.0.3-alpha. + + o Minor bugfixes (guards): + - In count_acceptable_nodes(), check if we have at least one bridge + or guard node, and two non-guard nodes for a circuit. Previously, + we have added up the sum of all nodes with a descriptor, but that + could cause us to build circuits that fail if we had either too + many bridges, or not enough guard nodes. Fixes bug 25885; bugfix + on 0.3.6.1-alpha. Patch by Neel Chauhan. + + o Minor bugfixes (IPv6): + - Fix tor_ersatz_socketpair on IPv6-only systems. Previously, the + IPv6 socket was bound using an address family of AF_INET instead + of AF_INET6. Fixes bug 28995; bugfix on 0.3.5.1-alpha. Patch from + Kris Katterjohn. + + o Minor bugfixes (logging): + - Rework rep_hist_log_link_protocol_counts() to iterate through all + link protocol versions when logging incoming/outgoing connection + counts. Tor no longer skips version 5 and we don't have to + remember to update this function when new link protocol version is + developed. Fixes bug 28920; bugfix on 0.2.6.10. + + o Minor bugfixes (networking): + - Introduce additional checks into tor_addr_parse() to reject + certain incorrect inputs that previously were not detected. Fixes + bug 23082; bugfix on 0.2.0.10-alpha. + + o Minor bugfixes (onion service v3, client): + - Avoid a BUG() stacktrace in case a SOCKS connection is found + waiting for the descriptor while we do have it in the cache. There + is a rare case when this can happen. Now, tor will recover and + retry the descriptor. Fixes bug 28669; bugfix on 0.3.2.4-alpha. + + o Minor bugfixes (periodic events): + - Refrain from calling routerlist_remove_old_routers() from + check_descriptor_callback(). Instead, create a new periodic event + that will run once every hour even if Tor is not configured as + onion router. Fixes bug 27929; bugfix on 0.2.8.1-alpha. + + o Minor bugfixes (pluggable transports): + - Make sure that data is continously read from standard out and + error of the PT child-process to avoid deadlocking when the pipes' + buffer is full. Fixes bug 26360; bugfix on 0.2.3.6-alpha. + + o Minor bugfixes (unit tests): + - Instead of relying on hs_free_all() to clean up all onion service + objects we created in test_build_descriptors(), deallocate them + one by one. This lets Coverity know that we are not leaking memory + here and fixes CID 1442277. Fixes bug 28989; bugfix + on 0.3.5.1-alpha. + + o Minor bugfixes (usability): + - Stop saying "Your Guard ..." in pathbias_measure_{use,close}_rate() + as that confusingly suggests that mentioned guard node is under + control and responsibility of end user, which it is not. Fixes bug + 28895; bugfix on Tor 0.3.0.1-alpha. + + o Code simplification and refactoring: + - Reimplement NETINFO cell parsing and generation to rely on + trunnel-generated wire format handling code. Closes ticket 27325. + - Remove unnecessarily unsafe code from the rust macro cstr!. Closes + ticket 28077. + - Rework SOCKS wire format handling to rely on trunnel-generated + parsing/generation code. Resolves ticket 27620. + - Split out bootstrap progress reporting from control.c into a + separate file. Part of ticket 27402. + - The .may_include files that we use to describe our directory-by- + directory dependency structure now describe a noncircular + dependency graph over the directories that they cover. Our + checkIncludes.py tool now enforces this. Closes ticket 28362. + + o Documentation: + - Mention that you cannot add new Onion Service if Tor is already + running with Sandbox enabled. Closes ticket 28560. + - Improve ControlPort description in tor manpage to mention that it + accepts address/port pair, and can be used multiple times. Closes + ticket 28805. + - Document the exact output of "tor --version". Closes ticket 28889. + + o Removed features: + - Stop responding to 'GETINFO status/version/num-concurring' and + 'GETINFO status/version/num-versioning' control port commands, as + those were deprecated back in 0.2.0.30. Also stop listing them in + output of 'GETINFO info/names'. Resolves ticket 28757. + - The scripts used to generate and maintain the list of fallback + directories have been extracted into a new "fallback-scripts" + repository. Closes ticket 27914. + + o Testing: + - Run shellcheck for stuff in scripts/ directory. Closes + ticket 28058. + - Write some unit tests for tokenize_string() and get_next_token() + functions. Resolves ticket 27625. + + o Code simplification and refactoring (onion service v3): + - Consolidate the authorized client descriptor cookie computation + code from client and service into one function. Closes + ticket 27549. + + o Code simplification and refactoring (shell scripts): + - Cleanup scan-build.sh to silence shellcheck warnings. Closes + ticket 28007. + - Fix issues that shellcheck found in chutney-git-bisect.sh. + Resolves ticket 28006. + - Fix issues that shellcheck found in updateRustDependencies.sh. + Resolves ticket 28012. + - Fix shellcheck warnings in cov-diff script.
