Ziyang Xuan 63b7c2ebcc net/af_packet: registration process optimization in packet_init() ... Now, register_pernet_subsys() and register_netdevice_notifier() are both after sock_register(). It can create PF_PACKET socket and process socket once sock_register() successfully. It is possible PF_PACKET socket is creating but register_pernet_subsys() and register_netdevice_notifier() are not registered yet. Thus net->packet.sklist_lock and net->packet.sklist will be accessed without initialization that is done in packet_net_init(). Although this is a low probability scenario. Move register_pernet_subsys() and register_netdevice_notifier() to the front in packet_init(). Correspondingly, adjust the unregister process in packet_exit().
