Changes in version 0.2.2.14-alpha - 2010-06-30
o Major bugfixes:
- Tor directory authorities no longer crash when started with a
cached-microdesc-consensus file in their data directory. Bugfix on
0.2.2.6-alpha, fixes bug 1532.
- Treat an unset $HOME like an empty $HOME rather than triggering an
assert. Fixes bug 1522; bugfix on tor-0.0.8pre1.
o Major features:
- Move to the June 2010 Maxmind GeoLite country db (rather than the
June 2009 ip-to-country GeoIP db) for our statistics that count
how many users relays are seeing from each country. Now we have
more accurate data for many African countries.
- Port Tor to build and run correctly on Windows CE systems, using
the wcecompat library. Contributed by Valerio Lupi.
- New "--enable-gcc-hardening" ./configure flag to turn on gcc
compile time hardening options. It ensures that signed ints have
defined behavior (-fwrapv), -D_FORTIFY_SOURCE=2 is enabled
(requiring -O2), stack smashing protection with canaries
(-fstack-protector-all), ASLR protection if supported by the
kernel (-fPIE, -pie). Additional security related warnings are
enabled. Verified to work on Mac OS X and Debian Lenny.
- New "--enable-linker-hardening" ./configure flag to turn on ELF
specific hardening features (relro, now). This does not work with
Mac OS X or any other non-ELF binary format.
o New directory authorities:
- Set up maatuska (run by Linus Nordberg) as the eighth v3 directory
authority.
o Minor features:
- New config option "WarnUnsafeSocks 0" disables the warning that
occurs whenever Tor receives only an IP address instead of a
hostname. Setups that do DNS locally over Tor are fine, and we
shouldn't spam the logs in that case.
- Convert the HACKING file to asciidoc, and add a few new sections
to it, explaining how we use Git, how we make changelogs, and
what should go in a patch.
o Minor bugfixes:
- Build correctly on OSX with zlib 1.2.4 and higher with all warnings
enabled.
- When a2x fails, mention that the user could disable manpages instead
of trying to fix their asciidoc installation.
- Where available, use Libevent 2.0's periodic timers so that our
once-per-second cleanup code gets called even more closely to
once per second than it would otherwise. Fixes bug 943.
- If you run a bridge that listens on multiple IP addresses, and
some user configures a bridge address that uses a different IP
address than your bridge writes in its router descriptor, and the
user doesn't specify an identity key, their Tor would discard the
descriptor because "it isn't one of our configured bridges", and
fail to bootstrap. Now believe the descriptor and bootstrap anyway.
Bugfix on 0.2.0.3-alpha.
- If OpenSSL fails to make a duplicate of a private or public key, log
an error message and try to exit cleanly. May help with debugging
if bug 1209 ever remanifests.
- Save a couple bytes in memory allocation every time we escape
certain characters in a string. Patch from Florian Zumbiehl.
- Make it explicit that we don't cannibalize one-hop circuits. This
happens in the wild, but doesn't turn out to be a problem because
we fortunately don't use those circuits. Many thanks to outofwords
for the initial analysis and to swissknife who confirmed that
two-hop circuits are actually created.
