Changes in version 0.4.3.8 - 2020-02-03
BLURB BLURB
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 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 the `config/parse_tcp_proxy_line` test so that it works
correctly on systems where the DNS provider hijacks invalid
queries. Fixes part of bug 40179; bugfix on 0.4.3.1-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 0.4.3.7 - 2020-11-12
Tor 0.4.3.7 backports several bugfixes from later releases. It
