Cong Wang 83f3153556 bpf, unix: Check socket type in unix_bpf_update_proto() ... As of now, only AF_UNIX datagram socket supports sockmap. But unix_proto is shared for all kinds of AF_UNIX sockets, so we have to check the socket type in unix_bpf_update_proto() to explicitly reject other types, otherwise they could be added into sockmap, too.
