[tor/master] TROVE-2017-004: Fix assertion failure in relay_send_end_cell_from_edge_
by nickm＠torproject.org 08 Jun '17

commit 79b59a2dfcb68897ee89d98587d09e55f07e68d7 Author: David Goulet <dgoulet(a)torproject.org> Date: Mon Jun 5 09:35:03 2017 -0400 TROVE-2017-004: Fix assertion failure in relay_send_end_cell_from_edge_ This fixes an assertion failure in relay_send_end_cell_from_edge_() when an origin circuit and a cpath_layer = NULL were passed. A service rendezvous circuit could do such a thing when a malformed BEGIN cell is received but shouldn't in the first place because the service needs to send an END cell on the circuit for which it can not do without a cpath_layer.
