tipc: add sock dump to new netlink api
Add TIPC_NL_SOCK_GET command to the new tipc netlink API. This command supports dumping of all available sockets with their associated connection or publication(s). It could be extended to reply with a single socket if the NLM_F_DUMP isn't set. The information about a socket includes reference, address, connection information / publication information. Netlink logical layout of response message: -> socket -> reference -> address [ -> connection -> node -> socket [ -> connected flag -> type -> instance ] ] [ -> publication flag ] Signed-off-by: Richard Alpe <richard.alpe@ericsson.com> Reviewed-by: Erik Hugne <erik.hugne@ericsson.com> Reviewed-by: Jon Maloy <jon.maloy@ericsson.com> Acked-by: Ying Xue <ying.xue@windriver.com> Signed-off-by: David S.
