Tor 0.3.3.4-alpha is released! nickm March 29, 2018 Hi! There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.3.3.4-alpha from the usual place on the website. If you don't build Tor from source, don't worry! Updated packages should be available over the coming weeks, with a new alpha Tor Browser release some time in April. Tor 0.3.3.4-alpha includes various bugfixes for issues found during the alpha testing of earlier releases in its series. We are approaching a stable 0.3.3.4-alpha release: more testing is welcome! Changes in version 0.3.3.4-alpha - 2018-03-29 New system requirements: When built with Rust, Tor now depends on version 0.2.39 of the libc crate. Closes tickets 25310 and 25664. Major bugfixes (relay, connection): If we have failed to connect to a relay and received a connection refused, timeout, or similar error (at the TCP level), do not try that same address/port again for 60 seconds after the failure has occurred. Fixes bug 24767; bugfix on 0.0.6. Minor features (geoip): Update geoip and geoip6 to the March 8 2018 Maxmind GeoLite2 Country database. Closes ticket 25469. Minor features (log messages): Improve log message in the out-of-memory handler to include information about memory usage from the different compression backends. Closes ticket 25372. Minor features (sandbox): Explicitly permit the poll() system call when the Linux seccomp2-based sandbox is enabled: apparently, some versions of libc use poll() when calling getpwnam(). Closes ticket 25313. Minor bugfixes (C correctness): Fix a very unlikely (impossible, we believe) null pointer dereference. Fixes bug 25629; bugfix on 0.2.9.15. Found by Coverity; this is CID 1430932. Minor bugfixes (channel, client): Better identify client connection when reporting to the geoip client cache. Fixes bug 24904; bugfix on 0.3.1.7. Minor bugfixes (compilation): Fix a C99 compliance issue in our configuration script that caused compilation issues when compiling Tor with certain versions of xtools. Fixes bug 25474; bugfix on 0.3.2.5-alpha. Minor bugfixes (controller, reliability): Avoid a (nonfatal) assertion failure when extending a one-hop circuit from the controller to become a multihop circuit. Fixes bug 24903; bugfix on 0.2.5.2-alpha. Minor bugfixes (networking): Tor will no longer reject IPv6 address strings from TorBrowser when they are passed as hostnames in SOCKS5 requests. Fixes bug 25036, bugfix on Tor 0.3.1.2. string_is_valid_hostname() will not consider IP strings to be valid hostnames. Fixes bug 25055; bugfix on Tor 0.2.5.5. Minor bugfixes (onion service v3): Avoid an assertion failure when the next the next onion service descriptor rotation type is out of sync with the consensus's valid-after time. Instead, log a warning message with extra information, so we can better hunt down the cause of this assertion. Fixes bug 25306; bugfix on 0.3.2.1-alpha. Minor bugfixes (testing): Avoid intermittent test failures due to a test that had relied on onion service introduction point creation finishing within 5 seconds of real clock time. Fixes bug 25450; bugfix on 0.3.1.3-alpha. Rust crates are now automatically detected and tested. Previously, some crates were not tested by `make test-rust` due to a static string in the `src/test/test_rust.sh` script specifying which crates to test. Fixes bug 25560; bugfix on 0.3.3.3-alpha. Minor bugfixes (testing, benchmarks): Fix a crash when running benchmark tests on win32 systems. The crash was due to a mutex that wasn't initialized before logging and options were initialized. Fixes bug 25479; bugfix on 0.3.3.3-alpha. Minor bugfixes (warnings, ipv6): Avoid a bug warning that could occur when trying to connect to a relay over IPv6. This warning would occur on a Tor instance that downloads router descriptors, but prefers to use microdescriptors. Fixes bug 25213; bugfix on 0.3.3.1-alpha. Code simplification and refactoring: Remove the old (deterministic) directory retry logic entirely: We've used exponential backoff exclusively for some time. Closes ticket 23814. Documentation: Improved the documentation of AccountingStart parameter. Closes ticket 23635. Update the documentation for "Log" to include the current list of logging domains. Closes ticket 25378.
