+Changes in version 0.3.5.13 - 2020-02-03 + Tor 0.3.5.13 backports numerous bugfixes from later releases, + including one that made v3 onion services more susceptible to + denial-of-service attacks, and a feature that makes some kinds of + DoS attacks harder to perform. + + o Major bugfixes (onion service v3, backport from 0.4.5.3-rc): + - Stop requiring a live consensus for v3 clients and services, and + allow a "reasonably live" consensus instead. This allows v3 onion + services to work even if the authorities fail to generate a + consensus for more than 2 hours in a row. Fixes bug 40237; bugfix + on 0.3.5.1-alpha. + + o Major bugfixes (stats, onion services, backport from 0.4.4.5): + - 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 Major feature (exit, backport from 0.4.5.5-rc): + - Re-entry into the network is now denied at the Exit level to all + relays' ORPorts and authorities' ORPorts and DirPorts. This change + should help mitgate a set of denial-of-service attacks. Closes + ticket 2667. + + o Minor feature (build system, backport from 0.4.5.4-rc): + - New "make lsp" command to generate the compile_commands.json file + used by the ccls language server. The "bear" program is needed for + this. Closes ticket 40227. + + o Minor features (compilation, backport from 0.4.5.2-rc): + - Disable deprecation warnings when building with OpenSSL 3.0.0 or + later. There are a number of APIs newly deprecated in OpenSSL + 3.0.0 that Tor still requires. (A later version of Tor will try to + stop depending on these APIs.) Closes ticket 40165. + + o Minor features (crypto, backport from 0.4.5.3-rc): + - Fix undefined behavior on our Keccak library. The bug only + appeared on platforms with 32-byte CPU cache lines (e.g. armv5tel) + and would result in wrong digests. Fixes bug 40210; bugfix on + 0.2.8.1-alpha. Thanks to Bernhard Übelacker, Arnd Bergmann and + weasel for diagnosing this. + + o Minor bugfixes (compatibility, backport from 0.4.5.1-rc): + - Strip '\r' characters when reading text files on Unix platforms. + This should resolve an issue where a relay operator migrates a + relay from Windows to Unix, but does not change the line ending of + Tor's various state files to match the platform, and the CRLF line + endings from Windows end up leaking into other files such as the + extra-info document. Fixes bug 33781; bugfix on 0.0.9pre5. + + o Minor bugfixes (compilation, backport from 0.4.5.1-rc): + - Resolve a compilation warning that could occur in + test_connection.c. Fixes bug 40113; bugfix on 0.2.9.3-alpha. + + o Minor bugfixes (compilation, backport from 0.4.5.3-rc): + - Fix a compilation warning about unreachable fallthrough + annotations when building with "--enable-all-bugs-are-fatal" on + some compilers. Fixes bug 40241; bugfix on 0.3.5.4-alpha. + + o Minor bugfixes (SOCKS5, backport from 0.4.5.3-rc): + - Handle partial SOCKS5 messages correctly. Previously, our code + would send an incorrect error message if it got a SOCKS5 request + that wasn't complete. Fixes bug 40190; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (testing, backport from 0.4.5.2-alpha): + - Fix our Python reference-implementation for the v3 onion service + handshake so that it works correctly with the version of hashlib + provided by Python 3.9. Fixes part of bug 40179; bugfix + on 0.3.1.6-rc. + - Fix the `tortls/openssl/log_one_error` test to work with OpenSSL + 3.0.0. Fixes bug 40170; bugfix on 0.2.8.1-alpha. + + Changes in version 0.3.5.12 - 2020-11-12 Tor 0.4.3.7 backports several bugfixes from later releases. It includes a fix for TROVE-2020-005, a security issue that could be
