This commit adds socket diagnostics capability for AF_TIPC in netlink family NETLINK_SOCK_DIAG in a new kernel module (diag.ko). The following are key design considerations: - config TIPC_DIAG has default y, like INET_DIAG. - only requests with flag NLM_F_DUMP is supported (dump all). - tipc_sock_diag_req message is introduced to send filter parameters. - the response attributes are of TLV, some nested. To avoid exposing data structures between diag and tipc modules and avoid code duplication, the following additions are required: - export tipc_nl_sk_walk function to reuse socket iterator. - export tipc_sk_fill_sock_diag to fill the tipc diag attributes. - create a sock_diag response message in __tipc_add_sock_diag defined in diag.c and use the above exported tipc_sk_fill_sock_diag to fill response.
