Subject: [PATCH 0/13] Implement dumping udp sockets via sock_diag netlink
Date: Fri, 09 Dec 2011 20:20:49 +0400 [thread overview]
Message-ID: <4EE23561.5020804@parallels.com> (raw)
Hi!
This is an extension of inet_diag module and the new udp_diag one. Plus
the patch for iproute's ss to dump udp sockets via netlink (applies on top
of previous patch for new NETLINK_SOCK_DIAG API [1]).
The overall idea is:
Patch the inet_diag module so that the protocol level handlers are called
indirectly from the very beginning, not just for getting the tcp_info bits.
Implement the udp_diag module that provides callbacks for IPPROTO_UDP and
IPPROTO_UDPLITE protocols.
The existing inet request packet (inet_diag_req) format used to request for
TCP/DCCP sockets is used for UDP socket as well, although not all the state
bits matter for UDP.
When sending back the reply the existing format (inet_diag_message) is used
as well. Some bits on this struct are meaningless for UDP, but I hope that
setting these to 0 and wasting some space on reply skb worth the saved amount
of new code on both -- the kernel side and the userspace side (i.e. ss tool).
The data that is stored in an nl attribute but doesn't exist for UDP is just
not provided.
