Public bug reported:
The upstream commit 9f834ec18defc369d73ccf9e87a2790bfa05bf46 was
backported to the 4.4.x xenial kernel series to address CVE-2019-11190.
However, the change introduces subtle changes to apparmor policy,
including in the apparmor regression tests. A sysfs entry was added in
later kernels to indicate this; 34c426acb75cc21bdf84685e106db0c1a3565057
upstream; this should be backported to the 4.4 kernels.
