COMMIT: http://review.gluster.org/13271 committed in master by Raghavendra G (rgowdapp) ------ commit 16f6579cb3e1214b1386fb530b8e16c8cbfdef33 Author: Mohammed Rafi KC <rkavunga> Date: Thu Jan 21 12:41:55 2016 +0530 protocol/server: Race between server_reconfigure and server_setvolume During server_reconfigure we authenticate each connected clients against the current options. To do this authentication we store previous values in a dictionary during the connection establishment phase (server_setvolume). If the authentication fails during reconfigure then we will disconnect the transport. Here it introduce a race between server_setvolume and reconfugure. If a reconfigure called before doing a setvolume, the transport will be disconnected Change-Id: Icce2c28a171481327a06efd3901f8a5ee67b05ab BUG: 1300564 Signed-off-by: Mohammed Rafi KC <rkavunga> Reviewed-on: http://review.gluster.org/13271 Smoke: Gluster Build System <jenkins.com> Reviewed-by: Raghavendra G <rgowdapp> CentOS-regression: Gluster Build System <jenkins.com> Reviewed-by: Raghavendra Talur <rtalur> NetBSD-regression: NetBSD Build System <jenkins.org>
