This one will implement all the interface of inet_diag, inet_diag_handler. which includes sctp_diag_dump, sctp_diag_dump_one and sctp_diag_get_info. It will work as a module, and register inet_diag_handler when loading. v2->v3: - fix the mistake in inet_assoc_attr_size(). - change inet_diag_msg_laddrs_fill() name to inet_diag_msg_sctpladdrs_fill. - change inet_diag_msg_paddrs_fill() name to inet_diag_msg_sctpaddrs_fill. - add inet_diag_msg_sctpinfo_fill() to make asoc/ep fill code clearer. - add inet_diag_msg_sctpasoc_fill() to make asoc fill code clearer. - merge inet_asoc_diag_fill() and inet_ep_diag_fill() to inet_sctp_diag_fill(). - call sctp_diag_get_info() directly, instead by handler, cause the caller is in the same file with it. - call lock_sock in sctp_tsp_dump_one() to make sure we call get sctp info safely. - after lock_sock(sk), we should check sk != assoc->base.sk. - change mem[SK_MEMINFO_WMEM_ALLOC] to asoc->sndbuf_used for asoc dump when asoc->ep->sndbuf_policy is set. don't use INET_DIAG_MEMINFO attr any more.
