commit 0f0d4356b21df48f1832c3de606eb70e16e94566 Author: Nick Mathewson <nickm@torproject.org> Date: Tue Jan 31 14:34:32 2017 -0500 Don't try to use confirmed_idx in remove_guard_from_...lists() Since we can call this function more than once before we update all the confirmed_idx fields, we can't rely on all the relays having an accurate confirmed_idx.
