Since a3ab6d42 "apparmor: convert libvirtd profile to a named profile"
the detection of the subelement for qemu_bridge_helper is wrong.
In combination with the older 123cc3e1 "apparmor: allow
/usr/lib/qemu/qemu-bridge-helper" it now detects qemu-bridge-helper no
more with its path, but instead as a proper subelement of the named profile
like: label=libvirtd//qemu_bridge_helper
In the same fashion the reverse rule in the qemu_bridge_helper
sub-profile still uses the path and not the named profile label.
Triggering denies like:
apparmor="DENIED" operation="file_inherit"
profile="libvirtd//qemu_bridge_helper" pid=5629 comm="qemu-bridge-hel"
family="unix" sock_type="stream" protocol=0 requested_mask="send receive"
denied_mask="send receive" addr=none peer_addr=none peer="libvirtd"
This patch fixes the unix socket rules for the communication between
libvirtd and qemu-bridge-helper to match that.
