Bug Description

Currently one cannot terminate Chromium from a guest session by executing e.g. "killall chromium". That's because current AppArmor profile for Chromium under guest sessions disallows it from receiveing SIGTERM.

In order to fix it, the following directive in abstractions/lightdm_chromium-browser

signal (receive, send) set=("exists") peer=/usr/lib/lightdm/lightdm-guest-session

should be changed to

signal (receive, send) set=("exists", "term") peer=/usr/lib/lightdm/lightdm-guest-session
