packet: call fanout_release, while UNREGISTERING a netdev
commit 6664498280cf17a59c3e7cf1a931444c02633ed1 upstream. If a socket has FANOUT sockopt set, a new proto_hook is registered as part of fanout_add(). When processing a NETDEV_UNREGISTER event in af_packet, __fanout_unlink is called for all sockets, but prot_hook which was registered as part of fanout_add is not removed. Call fanout_release, on a NETDEV_UNREGISTER, which removes prot_hook and removes fanout from the fanout_list. This fixes BUG_ON(!list_empty(&dev->ptype_specific)) in netdev_run_todo() Signed-off-by: Anoob Soman <anoob.soman@citrix.com> Signed-off-by: David S.
