commit 72832086e2144158308b30133aa15b39f0d2eb5d Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue Aug 8 20:07:39 2017 -0400 Use a single free-and-exit strategy in config_process_include. This avoids a double-free when a pointer already freed with tor_free(config_line) is freed again in the cleanup-and-exit code.

[tor/master] Fix check_expired_networkstatus_callback() if condition
by nickm＠torproject.org 11 Aug '17

commit 5b03c7ba6d899e19e8f3e0a58bd5df8bb7bbf1d0 Author: David Goulet <dgoulet(a)torproject.org> Date: Wed Aug 2 13:20:59 2017 -0400 Fix check_expired_networkstatus_callback() if condition The condition was always true meaning that we would reconsider updating our directory information every 2 minutes. If valid_until is 6am today, then now - 24h == 1pm yesterday which means that "valid_until < (now - 24h)" is false. But at 6:01am tomorrow, "valid_until < (now - 24h)" becomes true which is that point that we shouldn't trust the consensus anymore.
