For more + details, see the ticket description here: + https://trac.torproject.org/projects/tor/ticket/14917. Fixes + ticket 14917. + + o Major features (relay, Ed25519): + - Significant improvements to the usability of relay-side Ed25519 + key management. Log messages are better, and the code can recover + from far more failure conditions. Thanks to "s7r" for reporting + and diagnosing so many of these! + + o Major bugfixes (relay, Ed25519): + - Avoid crashing on 'tor --keygen'. Fixes bug 16679; bugfix on + 0.2.7.2-alpha. Reported by "s7r". + - Improve handling of expired signing keys along with offline master + keys. Fixes bug 16685; bugfix on 0.2.7.2-alpha. Reported by "s7r". + + o Major enhancements (performance testing): + - Add chutney performance testing support to src/test/test- + network.sh The following arguments change how chutney verifies the + network: "--bytes n" sends n bytes per test connection; + "--connections n" makes n test connections per client; and + "--hs-multi-client 1" makes each client connect to each HS. + Requires the corresponding chutney performance testing changes. + Note: using --connections 7 or greater on a HS will trigger issue + 15937. Patch by "teor". Closes ticket 14175. + + o Minor features: + - Try harder to normalize the exit status of the Tor process to the + standard-provided range. Fixes bug 16975; bugfix on every version + of Tor ever. + - Update geoip and geoip6 to the July 8 2015 Maxmind GeoLite2 + Country database. + + o Minor features (client-side privacy): + - Indefinitely extend circuit lifespan by resetting dirtyness, if + IsolateSOCKSAuth is in use, the new `KeepAliveIsolateSOCKSAuth` + option is set, and streams with SOCKS authentication are attached + to the circuit. Implements feature 15482. + + o Minor features (compilation): + - Give a warning as early as possible when trying to build with an + unsupported OpenSSL version. Closes ticket 16901. + + o Minor features (Hidden service directory): + - Relays need to have the Fast flag to get the HSDir flag. As this + is being written, we'll go from 2745 HSDirs down to 2342, a ~14% + drop. Fixes ticket 15963. + + o Minor features (hidden Service Statistics): + - Turn on hidden service statistics collection by setting the torrc + option HiddenServiceStatistics to "1" by default. Closes + ticket 15254. + + o Minor features (hidden service): + - Client now uses an introduction point failure cache to know when + to fetch or keep a descriptor in their cache. + + When fetching a descriptor, for every introduction points in it, + we look them up in the failure cache to know if we keep the + descriptor or not. For this to work, everytime an introduction + points is discarded (ex: receiving a NACK), we note it down in our + introduction cache. If all introduction points for an onion + service are in our failure cache, we discard the descriptor and + fetch a new one. + + See rendcache.c for a detailed explanation of the cache's + behavior. Closes ticket 16389. + + o Minor features (performance): + - Improve the runtime speed of Ed25519 operations and Curve25519 + keypair generation when built targeting 32 bit x86 platforms with + SSE2 available. Implements ticket 16535. + - Improve the runtime speed of Ed25519 signature verification by + using Ed25519-donna's batch verification support when there are a + lot of signatures to verify at once. Implements ticket 16533. + + o Minor features (testing): + - Autodetect CHUTNEY_PATH if the chutney and tor sources are side- + by-side in the same parent directory. Closes ticket 16903. Patch + by "teor". + + o Minor features (testing, authorities): + - New TestingDirAuthVote{Exit,Guard,HSDir}IsStrict flags. "A node + will never receive the corresponding flag unless that node is + specified in the TestingDirAuthVote{Exit,Guard,HSDir} list, + regardless of its uptime, bandwidth, exit policy, or DirPort". + Closes ticket 14882. Patch by "robgjansen", modified by "teor" as + VoteOnHidServDirectoriesV2 is now obsolete. Commit message and + changes file by "teor" & "robgjansen". + + o Minor features (testing, authorities, documentation): + - Fix an error in the manual page and comments for + TestingDirAuthVoteHSDir[IsStrict], which suggested that a HSDir + required "ORPort connectivity". While this is true, it is in no + way unique to the HSDir flag. Of all the flags, only HSDirs need a + DirPort configured in order for the authorities to assign that + particular flag. Fixed as part of 14882. Patch by "teor". Bugfix + on 0.2.6.3 (f9d57473e1ff on 10 January 2015). + + o Minor features (testing, bridges, hidden services): + - Make "bridges+hs" the default test network. This tests almost all + tor functionality during make test-network, while allowing tests + to succeed on non-IPv6 systems. Requires chutney commit 396da92 in + test-network-bridges-hs. Closes tickets 16945 (tor), 16946 + (chutney) . Patches by "teor". + + o Minor bugfixes: + - Check correctly for windows socket errors in the workqueue + backend. Fixes bug 16741; bugfix on 0.2.6.3-alpha. + - Ensure that worker threads actually exit when a fatal error or + shutdown is indicated. This doesn't currently affect the behaviour + of Tor, because Tor never indicates fatal error or shutdown except + in its unit tests. Fixes bug 16868; bugfix on 0.2.6.3-alpha. + - Fix an usage message of tor-resolve(1) so that it no longer lists + the removed -F option. Fixes bug 16913; bugfix on + Tor 0.2.2.28-beta. + - Fix the behavior of crypto_time_t when told to consider times + before 1970. (These times were possible when running in a + simulated network environment where time()'s output starts at + zero.) Fixes bug 16980; bugfix on 0.2.7.1-alpha. + - When calling channel_free_list(), avoid calling smartlist_remove() + while inside a FOREACH loop. This partially reverts commit + 17356fe7fd96af where the correct SMARTLIST_DEL_CURRENT was + removed. Fixes bug 16924; bugfix on 0.2.4.4-alpha. + - When logging malformed hostnames in socks5 requests, respect + SafeLogging configuration. Fixes bug 16891; bugfix on 0.1.1.16-rc. + - include the TUNING document in our source tarball. It is referred + to in the ChangeLog and an error message. Fixes bug 16929; bugfix + on 0.2.6.1-alpha. + + o Minor bugfix (open file limit): + - Fix set_max_file_descriptors() to set by default the max open file + limit to the current limit in case setrlimit() fails so we at + least have a usable value; Fixes bug 16274; bugfix on tor- + 0.2.0.10-alpha. Patch by dgoulet. + + o Minor bugfixes (authority): + - Don't assign "HSDir" to a router if it isn't Valid and Running. + Fixes bug 16524; bugfix on 0.2.7.2-alpha. + - Downgrade log messages about Ed25519 key issues, if they are in + old cached router descriptors. Fixes part of bug 16286; bugfix + on 0.2.7.2-alpha. + - When we find an Ed25519 key issue in a cached descriptor, stop + saying the descriptor was just "uploaded". Fixes another part of + bug 16286; bugfix on 0.2.7.2-alpha. + + o Minor bugfixes (control port): + - Control port was using set_max_file_descriptors() with a limit set + to 0 to get the max value. A recent fix made this use case return + an error and introduced dead code in that function. This triggered + a warning that our limit (ConnLimit) was invalid but in reality it + was not. + + Now, to the control port uses a specific getter function to query + the value and set_max_file_descriptors() should never be used + again for that purpose. Fixes bug 16697; bugfix on 0.2.7.2-alpha. + + o Minor bugfixes (Ed25519): + - Fix a memory leak when reading router descriptors with expired + Ed25519 certificate. Fixes bug 16539; bugfix on 0.2.7.2-alpha. + + o Minor bugfixes (linux seccomp2 sandbox): + - Allow bridge authorities to run correctly under the seccomp2 + sandbox. Fixes bug 16964; bugfix on 0.2.5.1-alpha. + - Allow routers with ed25519 keys to run correctly under the + seccomp2 sandbox. Fixes bug 16965; bugfix on 0.2.7.2-alpha. + + o Minor bugfixes (relay): + - Unblock threads before releasing the mutex to ensure predictable + scheduling behavior. Fixes bug 16644; bugfix on 0.2.6.3-alpha. + + o Code simplification and refactoring: + - Change the function that's called when we need to retry all + downloads so that it only reschedules the downloads to happen + immediately, rather than launching them all at once itself. This + further simplifies Tor's callgraph. + - Move some format-parsing functions out of crypto.c and + crypto_curve25519.c into crypto_format.c and/or util_format.c. + - Move the client-only parts of init_keys() into a separate + function. Closes ticket 16763. + - Simplify the microdesc_free() implementation so that it no longer + appears (to code analysis tools) to potentially invoke a huge + suite of other microdesc functions. + - Simply the control graph further by deferring the inner body of + directory_all_unreachable() into a callback. Closes ticket 16762. + - Treat the loss of an owning controller as equivalent to a SIGTERM + signal. This removes a tiny amount of duplicated code, and + simplifies our callgraph. Closes ticekt 16788. + - When generating an event to send to the controller, we no longer + put the event over the network immediately. Instead, we queue + these events, and use a Libevent callback to deliver them. This + change simplifies Tor's callgraph by reducing the number of + functions from which all other Tor functions are reachable. Closes + ticket 16695. + - Wrap windows-only C files inside '#ifdef _WIN32' so that tools + that try to scan or compile every file on Unix won't decide that + they are broken. + + o Code simplifications and refactoring: + - Remove the unused "nulterminate" argument from buf_pullup(). + + o Documentation: + - Recommend a 40 GB example AccountingMax in torrc.sample rather + than a 4 GB max. Closes ticket 16742. + + o Removed code: + - The internal pure-C tor-fw-helper tool is now removed from the Tor + distribution, in favor of the pure-Go clone available from + https://github.com/Yawning/tor-fw-helper . The libraries used by + the C tor-fw-helper are not, in our opinion, very confidence- + inspiring in their secure-proggramming techniques. Closes + ticket 13338. + + o Removed features: + - Remove the code that would try to aggressively flush controller + connections while writing to them. This code was introduced in + 0.1.2.7-alpha, in order to keep output buffers from exceeding + their limits. But there is no longer a maximum output buffer size, + and flushing data in this way caused some undesirable recursions + in our call graph. Closes ticket 16480. + + o Testing: + - Add a new set of callgraph analysis scripts that use clang to + produce a list of which Tor functions are reachable from which + other Tor functions. We're planning to use these to help simplify + our code structure by identifying illogical dependencies. + - Add new 'test-full' and 'test-full-online' targets to run all + tests, including integration tests with stem and chutney. + - Make the test-workqueue test work on windows by initializing the + network before we begin. + - New make target (make test-network-all) to run multiple applicable + chutney test cases. Patch from Teor; closes 16953. + - Unit test dns_resolve(), dns_clip_ttl() and dns_get_expiry_ttl() + functions in dns.c. Implements a portion of ticket 16831. + - When building Tor with testing coverage enabled, run Chutney tests + (if any) using the 'tor-cov' coverage binary. + - When running test-network or test-stem, check for the absence of + stem/chutney before doing any build operations. + + Changes in version 0.2.7.2-alpha - 2015-07-27 This, the second alpha in the Tor 0.2.7 series, has a number of new features, including a way to manually pick the number of introduction |
