From eaaa31392690c7609f7afeec5ba38a79d009842d Mon Sep 17 00:00:00 2001 From: Andrey Vagin Date: Thu, 21 Mar 2013 20:33:48 +0400 Subject: netlink: Diag core and basic socket info dumping (v2) The netlink_diag can be built as a module, just like it's done in unix sockets. The core dumping message carries the basic info about netlink sockets: family, type and protocol, portis, dst_group, dst_portid, state. Groups can be received as an optional parameter NETLINK_DIAG_GROUPS. Netlink sockets cab be filtered by protocols. The socket inode number and cookie is reserved for future per-socket info retrieving. The per-protocol filtering is also reserved for future by requiring the sdiag_protocol to be zero. The file /proc/net/netlink doesn't provide enough information for dumping netlink sockets. It doesn't provide dst_group, dst_portid, groups above 32. v2: fix NETLINK_DIAG_MAX. Now it's equal to the last constant. Acked-by: Pavel Emelyanov Cc: "David S. Miller" Cc: Eric Dumazet Cc: Pablo Neira Ayuso Cc: "Eric W.
