Subject: xwayland: Enable access control on open sockets
Author: Ray Strode <rstrode@redhat.com>
Path-mainline: Upstream
Git-commit: c4534a38b68aa07fb82318040dc8154fb48a9588
References: bnc#934102 CVE-2015-3164
Signed-off-by: Michal Srb <msrb@suse.com>

Xwayland currently allows wide-open access to the X sockets
it listens on, ignoring Xauth access control.

This commit makes sure to enable access control on the sockets,
so one user can't snoop on another user's X-over-wayland
applications.
