(cherry picked from commit 6ba383c5) Restrict unix_dgram_socket and unix_stream_socket to a whitelist. Disallow all ioctls for netlink_selinux_socket and netlink_route_socket. Neverallow third party app use of all ioctls other than unix_dgram_socket, unix_stream_socket, netlink_selinux_socket, netlink_route_socket, tcp_socket, udp_socket and rawip_socket.
