apparmor: Allow pasta to remount /proc, access entries under its own copy
Since commit b0e450aa8500 ("pasta: Detach mount namespace, (re)mount procfs before spawning command"), we need to explicitly permit mount of /proc, and access to entries under /proc/PID/net (after remount, that's what AppArmor sees as path). Fixes: b0e450aa8500 ("pasta: Detach mount namespace, (re)mount procfs before spawning command") Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
