Tor 0.2.1.13-alpha includes another big pile of minor bugfixes and
cleanups. We're finally getting close to a release candidate.

Changes in version 0.2.1.13-alpha - 2009-03-09
Major bugfixes:

  • Correctly update the list of which countries we exclude as
    exits, when the GeoIP file is loaded or reloaded. Diagnosed by
    lark. Bugfix on 0.2.1.6-alpha.

Minor bugfixes (on 0.2.0.x and earlier):

  • Automatically detect MacOSX versions earlier than 10.4.0, and
    disable kqueue from inside Tor when running with these versions.
    We previously did this from the startup script, but that was no
    help to people who didn't use the startup script. Resolves bug 863.
  • When we had picked an exit node for a connection, but marked it as
    "optional", and it turned out we had no onion key for the exit,
    stop wanting that exit and try again. This situation may not
    be possible now, but will probably become feasible with proposal
    158. Spotted by rovv. Fixes another case of bug 752.
  • Clients no longer cache certificates for authorities they do not
    recognize. Bugfix on 0.2.0.9-alpha.
  • When we can't transmit a DNS request due to a network error, retry
    it after a while, and eventually transmit a failing response to
    the RESOLVED cell. Bugfix on 0.1.2.5-alpha.
  • If the controller claimed responsibility for a stream, but that
    stream never finished making its connection, it would live
    forever in circuit_wait state. Now we close it after SocksTimeout
    seconds. Bugfix on 0.1.2.7-alpha; reported by Mike Perry.
  • Drop begin cells to a hidden service if they come from the middle
    of a circuit. Patch from lark.
  • When we erroneously receive two EXTEND cells for the same circuit
    ID on the same connection, drop the second. Patch from lark.
  • Fix a crash that occurs on exit nodes when a nameserver request
    timed out. Bugfix on 0.1.2.1-alpha; our CLEAR debugging code had
    been suppressing the bug since 0.1.2.10-alpha. Partial fix for
    bug 929.
  • Do not assume that a stack-allocated character array will be
    64-bit aligned on platforms that demand that uint64_t access is
    aligned. Possible fix for bug 604.
  • Parse dates and IPv4 addresses in a locale- and libc-independent
    manner, to avoid platform-dependent behavior on malformed input.
  • Build correctly when configured to build outside the main source
    path. Patch from Michael Gold.
  • We were already rejecting relay begin cells with destination port
    of 0. Now also reject extend cells with destination port or address
    of 0. Suggested by lark.

Minor bugfixes (on 0.2.1.x):

  • Don't re-extend introduction circuits if we ran out of RELAY_EARLY
    cells. Bugfix on 0.2.1.3-alpha. Fixes more of bug 878.
  • If we're an exit node, scrub the IP address to which we are exiting
    in the logs. Bugfix on 0.2.1.8-alpha.

Minor features:

  • On Linux, use the prctl call to re-enable core dumps when the user
    is option is set.
  • New controller event NEWCONSENSUS that lists the networkstatus
    lines for every recommended relay. Now controllers like Torflow
    can keep up-to-date on which relays they should be using.
  • Update to the "February 26 2009" ip-to-country file.
