  o Minor bugfix (entry guards):
    - Silence a BUG() warning when attempting to use a guard whose descriptor
      we don't know and make this scenario more unlikely to happen. Fixes bug
      21415; bugfix on 0.3.0.1-alpha.
Improve descriptor checks in the new guard algorithm. - Make sure we check at least two guards for descriptor before making circuits. We typically use the first primary guard for circuits, but it can also happen that we use the second primary guard (e.g. if we pick our first primary guard as an exit), so we should make sure we have descriptors for both of them. - Remove BUG() from the guard_has_descriptor() check since we now know that this can happen in rare but legitimate situations as well, and we should just move to the next guard in that case. 2017-03-01 11:38:12 +01:00			`o Minor bugfix (entry guards):`
