Title:
firefox crashes with MOZ_ENABLE_WAYLAND=1 when apparmor profile is
enforced
Status in firefox package in Ubuntu:
Fix Committed
Bug description:
Recently I decided to try running firefox 80 directly via Wayland,
instead of via X11. It crashed. (I haven't tried any previous
versions.)
I found the following in /var/log/audit/audit.log:
type=AVC msg=audit(1599023168.948:3997869): apparmor="DENIED"
operation="mknod" profile="firefox"
name="/dev/shm/wayland.mozilla.ipc.0" pid=1042373 comm="Compositor"
requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000
I added the following to /etc/apparmor.d/local/usr.bin.firefox:
/dev/shm/wayland.mozilla.* rw,
reloaded the profile:
sudo apparmor_parser -r < /etc/apparmor.d/usr.bin.firefox
and now it works.
