commit d8509b450a1de815399a42b5df8c6b25789429c7 Author: David Goulet <dgoulet@torproject.org> Date: Tue May 1 10:15:28 2018 -0400 vote: Return error when adding vote/signature if no dirauth module Commit 0f3b765b3c8ba6f4f105440861e87ecaf4ea4323 added tor_assert_nonfatal_unreached() to dirvote_add_vote() and dirvote_add_signatures() when the dirauth module is disabled. However, they need to return a value. Furthermore, the dirvote_add_vote() needs to set the msg_out and status_out so it can be sent back. Else, uninitialized values would be used.
