tor/changes/bug9017

  o Major bugfixes:
    - Avoid an assertion failure on OpenBSD (and perhaps other BSDs)
      when an exit connection with optimistic data succeeds immediately
      rather than returning EINPROGRESS. Fixes bug 9017; bugfix on
      0.2.3.1-alpha.
Fix (Open?)BSD fast-connect bug with optimistic data. There's an assertion failure that can occur if a connection has optimistic data waiting, and then the connect() call returns 0 on the first attempt (rather than -1 and EINPROGRESS). That latter behavior from connect() appears to be an (Open?)BSDism when dealing with remote addresses in some cases. (At least, I've only seen it reported with the BSDs under libevent, even when the address was 127.0.0.1. And we've only seen this problem in Tor with OpenBSD.) Fixes bug 9017; bugfix on 0.2.3.1-alpha, which first introduced optimistic data. (Although you could also argue that the commented-out connection_start_writing in 155c9b80 back in 2002 is the real source of the issue.) 2013-06-10 18:14:49 +02:00			`o Major bugfixes:`
