Tor 0.1.0.16 is a bugfix release. It fixes nine rare crash bugs, and includes backports from the 0.1.1.x tree to be more aggressive about retrying failed streams. http://tor.eff.org/download o Crash bugfixes on 0.1.0.x: - On Windows, build with a libevent patch from "I-M Weasel" to avoid corrupting the heap, losing FDs, or crashing when we need to resize the fd_sets. (This affects the Win32 binaries, not Tor's sources.) - It turns out sparc64 platforms crash on unaligned memory access too -- so detect and avoid this. - Handle truncated compressed data correctly (by detecting it and giving an error). - Fix possible-but-unlikely free(NULL) in control.c. - When we were closing connections, there was a rare case that stomped on memory, triggering seg faults and asserts. - Avoid potential infinite recursion when building a descriptor. (We don't know that it ever happened, but better to fix it anyway.) - We were neglecting to unlink marked circuits from soon-to-close OR connections, which caused some rare scribbling on freed memory. - Fix a memory stomping race bug when closing the joining point of two rendezvous circuits. - Fix an assert in time parsing found by Steven Murdoch. o Other bugfixes on 0.1.0.x: - When we're doing reachability testing, provide more useful log messages so the operator knows what to expect. - Do not check whether DirPort is reachable when we are suppressing advertising it because of hibernation. - When building with -static or on Solaris, we sometimes needed -ldl. - One of the dirservers (tor26) changed its IP address. - When we're deciding whether a stream has enough circuits around that can handle it, count the freshly dirty ones and not the ones that are so dirty they won't be able to handle it. - When we're expiring old circuits, we had a logic error that caused us to close new rendezvous circuits rather than old ones. - Give a more helpful log message when you try to change ORPort via the controller: you should upgrade Tor if you want that to work. - We were failing to parse Tor versions that start with "Tor ". - Tolerate faulty streams better: when a stream fails for reason exitpolicy, stop assuming that the router is lying about his exit policy. When a stream fails for reason misc, allow it to retry just as if it was resolvefailed. When a stream has failed three times, reset its failure count so we can try again and get all three tries.
