commit 3acf6cafbb655a73f0a52b38a0dbd94eb5befa3f Author: Nick Mathewson nickm@torproject.org Date: Tue Feb 27 16:55:08 2018 -0500

Make a changelog for 0.3.2.10

(Note that two entries are marked OMIT: they are bugfixes on #24902 that we're backporting along with the #24902 code. I think that means that we don't backport their changelog entries, since they are bugfixes on a later version of Tor?) --- ChangeLog | 145 +++++++++++++++++++++++++++++++++++++++++++++ changes/bug21074_downgrade | 4 -- changes/bug24526 | 4 -- changes/bug24652 | 6 -- changes/bug24700 | 4 -- changes/bug24826_031 | 4 -- changes/bug24859 | 4 -- changes/bug24894 | 5 -- changes/bug24895 | 8 --- changes/bug24898 | 8 --- changes/bug24952 | 5 -- changes/bug24972 | 4 -- changes/bug24975 | 6 -- changes/bug24976 | 5 -- changes/bug24978 | 7 --- changes/bug25005 | 4 -- changes/bug25070 | 3 - changes/bug25105 | 5 -- changes/bug25223 | 4 -- changes/geoip-2018-02-07 | 4 -- changes/ticket24902 | 13 ---- changes/ticket25122 | 4 -- changes/ticket25170 | 5 -- changes/ticket25202 | 4 -- changes/ticket25323 | 4 -- 25 files changed, 145 insertions(+), 124 deletions(-)

It + backports a number of bugfixes, including important fixes for security + issues. + + BLURB HERE. + + o Major features (denial-of-service mitigation, backport from 0.3.3.2-alpha): + - Give relays some defenses against the recent network overload. We + start with three defenses (default parameters in parentheses). + First: if a single client address makes too many concurrent + connections (>100), hang up on further connections. Second: if a + single client address makes circuits too quickly (more than 3 per + second, with an allowed burst of 90) while also having too many + connections open (3), refuse new create cells for the next while + (1-2 hours). Third: if a client asks to establish a rendezvous + point to you directly, ignore the request. These defenses can be + manually controlled by new torrc options, but relays will also + take guidance from consensus parameters, so there's no need to + configure anything manually. Implements ticket 24902. + + o Major bugfixes (onion services, retry behavior, backport from 0.3.3.1-alpha): + - Fix an "off by 2" error in counting rendezvous failures on the + onion service side. While we thought we would stop the rendezvous + attempt after one failed circuit, we were actually making three + circuit attempts before giving up. Now switch to a default of 2, + and allow the consensus parameter "hs_service_max_rdv_failures" to + override. Fixes bug 24895; bugfix on 0.0.6. + - New-style (v3) onion services now obey the "max rendezvous circuit + attempts" logic. Previously they would make as many rendezvous + circuit attempts as they could fit in the MAX_REND_TIMEOUT second + window before giving up. Fixes bug 24894; bugfix on 0.3.2.1-alpha. + + o Major bugfixes (protocol versions, backport from 0.3.3.2-alpha): + - Add Link protocol version 5 to the supported protocols list. Fixes + bug 25070; bugfix on 0.3.1.1-alpha. + + o Major bugfixes (relay, backport from 0.3.3.1-alpha): + - Fix a set of false positives where relays would consider + connections to other relays as being client-only connections (and + thus e.g. deserving different link padding schemes) if those + relays fell out of the consensus briefly. Now we look only at the + initial handshake and whether the connection authenticated as a + relay. Fixes bug 24898; bugfix on 0.3.1.1-alpha. + + o Major bugfixes (scheduler, consensus, backport from 0.3.3.2-alpha): + - The scheduler subsystem was failing to promptly notice changes in + consensus parameters, making it harder to switch schedulers + network-wide. Fixes bug 24975; bugfix on 0.3.2.1-alpha. + + o Minor features (denial-of-service avoidance, backport from 0.3.3.2-alpha): + - Make our OOM handler aware of the geoip client history cache so it + doesn't fill up the memory. This check is important for IPv6 and + our DoS mitigation subsystem. Closes ticket 25122. + + o Minor features (compatibility, OpenSSL, backport from 0.3.3.3-alpha): + - Tor will now support TLS1.3 once OpenSSL 1.1.1 is released. + Previous versions of Tor would not have worked with OpenSSL 1.1.1, + since they neither disabled TLS 1.3 nor enabled any of the + ciphersuites it requires. Here we enable the TLS 1.3 ciphersuites. + Closes ticket 24978. + + o Minor features (geoip): + - Update geoip and geoip6 to the February 7 2018 Maxmind GeoLite2 + Country database. + + o Minor features (logging, diagnostic, backport from 0.3.3.2-alpha): + - When logging a failure to check a hidden service's certificate, + also log what the problem with the certificate was. Diagnostic + for ticket 24972. + + o Minor bugfix (channel connection, backport from 0.3.3.2-alpha): + - Use the actual observed address of an incoming relay connection, + not the canonical address of the relay from its descriptor, when + making decisions about how to handle the incoming connection. + Fixes bug 24952; bugfix on 0.2.4.11-alpha. Patch by "ffmancera". + + o Minor bugfix (directory authority, backport from 0.3.3.2-alpha): + - Directory authorities, when refusing a descriptor from a rejected + relay, now explicitly tell the relay (in its logs) to set a valid + ContactInfo address and contact the bad-relays@ mailing list. + Fixes bug 25170; bugfix on 0.2.9.1. + + o Minor bugfixes (build, rust, backport from 0.3.3.1-alpha): + - When building with Rust on OSX, link against libresolv, to work + around the issue at https://github.com/rust-lang/rust/issues/46797. + Fixes bug 24652; bugfix on 0.3.1.1-alpha. + + + [[[[ OMIT + o Minor bugfixes (DoS mitigation): + - Add extra safety checks when refilling the circuit creation bucket to + ensure we never set a value that is above the allowed burst.
