It fixes + several bugs from earlier versions, including one affecting DoS + defenses on bridges using pluggable transports. + + o Major bugfixes (DoS defenses, bridges, pluggable transport): + - Fix a bug that was preventing DoS defenses from running on bridges + with a pluggable transport. Previously, the DoS subsystem was not + given the transport name of the client connection, thus failed to + find the GeoIP cache entry for that client address. Fixes bug + 33491; bugfix on 0.3.3.2-alpha. + + o Minor feature (sendme, flow control): + - Default to sending SENDME version 1 cells. (Clients are already + sending these, because of a consensus parameter telling them to do + so: this change only affects what clients would do if the + consensus didn't contain a recommendation.) Closes ticket 33623. + + o Minor features (testing): + - The unit tests now support a "TOR_SKIP_TESTCASES" environment + variable to specify a list of space-separated test cases that + should not be executed. We will use this to disable certain tests + that are failing on Appveyor because of mismatched OpenSSL + libraries. Part of ticket 33643. + + o Minor bugfixes (--disable-module-relay): + - Fix an assertion failure when Tor is built without the relay + module, and then invoked with the "User" option. Fixes bug 33668; + bugfix on 0.4.3.1-alpha. + + o Minor bugfixes (--disable-module-relay,--disable-module-dirauth): + - Set some output arguments in the relay and dirauth module stubs, + to guard against future stub argument handling bugs like 33668. + Fixes bug 33674; bugfix on 0.4.3.1-alpha. + + o Minor bugfixes (build system): + - Correctly output the enabled module in the configure summary. + Before that, the list shown was just plain wrong. Fixes bug 33646; + bugfix on 0.4.3.2-alpha. + + o Minor bugfixes (client, IPv6): + - Stop forcing all non-SocksPorts to prefer IPv6 exit connections. + Instead, prefer IPv6 connections by default, but allow users to + change their configs using the "NoPreferIPv6" port flag. Fixes bug + 33608; bugfix on 0.4.3.1-alpha. + - Revert PreferIPv6 set by default on the SocksPort because it broke + the torsocks use case. Tor doesn't have a way for an application + to request the hostname to be resolved for a specific IP version, + but torsocks requires that. Up until now, IPv4 was used by default + so torsocks is expecting that, and can't handle a possible IPv6 + being returned. Fixes bug 33804; bugfix on 0.4.3.1-alpha. + + o Minor bugfixes (key portability): + - When reading PEM-encoded key data, tolerate CRLF line-endings even + if we are not running on Windows. Previously, non-Windows hosts + would reject these line-endings in certain positions, making + certain key files hard to move from one host to another. Fixes bug + 33032; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (logging): + - Flush stderr, stdout, and file logs during shutdown, if supported + by the OS. This change helps make sure that any final logs are + recorded. Fixes bug 33087; bugfix on 0.4.1.6. + - Stop closing stderr and stdout during shutdown. Closing these file + descriptors can hide sanitiser logs. Fixes bug 33087; bugfix + on 0.4.1.6. + + o Minor bugfixes (onion services v3): + - Relax severity of a log message that can appear naturally when + decoding onion service descriptors as a relay. Also add some + diagnostics to debug any future bugs in that area. Fixes bug + 31669; bugfix on 0.3.0.1-alpha. + - Block a client-side assertion by disallowing the registration of + an x25519 client auth key that's all zeroes. Fixes bug 33545; + bugfix on 0.4.3.1-alpha. Based on patch from "cypherpunks". + + o Code simplification and refactoring: + - Disable our coding standards best practices tracker in our git + hooks. (0.4.3 branches only.) Closes ticket 33678. + + o Testing: + - Avoid conflicts between the fake sockets in tor's unit tests, and + real file descriptors. Resolves issues running unit tests with + GitHub Actions, where the process that embeds or launches the + tests has already opened a large number of file descriptors. Fixes + bug 33782; bugfix on 0.2.8.1-alpha. Found and fixed by + Putta Khunchalee. + + o Testing (CI): + - In our Appveyor Windows CI, copy required DLLs to test and app + directories, before running tor's tests. This ensures that tor.exe + and test*.exe use the correct version of each DLL. This fix is not + required, but we hope it will avoid DLL search issues in future. + Fixes bug 33673; bugfix on 0.3.4.2-alpha. + - On Appveyor, skip the crypto/openssl_version test, which is + failing because of a mismatched library installation. Fix + for 33643. + + Changes in version 0.4.3.3-alpha - 2020-03-18 Tor 0.4.3.3-alpha fixes several bugs in previous releases, including TROVE-2020-002, a major denial-of-service vulnerability that affected
