correct for socket support, the network and af_unix mediation patches
are not present in the backport.

as for policy namespace support it has existed in various forms since
apparmor was included in 2.6.36, its just a matter of what interfaces
are supported the 4.11, 4.12, and 4.13 kernels each added support for
newer interfaces and reworked apparmorfs to better support policy
namespaces.

Full support of apparmor policy around linux namespaces (mount, user,
pid, ...) is still a wip
