File u_connection-avoid-crash-when-CloseWellKnownConnections-gets-called-twice.patch of Package xorg-x11-server.390
From: Egbert Eich <eich@suse.de> Date: Fri May 23 20:08:29 2014 +0200 Subject: [PATCH]connection: avoid crash when CloseWellKnownConnections() gets called twice Patch-mainline: to be upstreamed Git-commit: 74472c4e8e4c873014554f321ec2086066126297 Git-repo: References: bnc#879666, bnc#879489 Signed-off-by: Egbert Eich <eich@suse.com> CloseWellKnownConnections() closes all connections and deallocates their data. Thus all entries in ListenTransConns are invalid. To avoid access to those entries set ListenTransCount to 0. This avoids crashes when CloseWellKnownConnections() is called twice for instance when FatalError() is called on Xserver shutdown.
