udp_diag: Fix socket skipping within chain

2015-01-27T08:02:41+00:00

While working on rhashtable walking I noticed that the UDP diag
dumping code is buggy.  In particular, the socket skipping within
a chain never happens, even though we record the number of sockets
that should be skipped.

As this code was supposedly copied from TCP, this patch does what
TCP does and resets num before we walk a chain.

netlink: rename ssk to sk in struct netlink_skb_params

2013-04-19T18:57:56+00:00

Memory mapped netlink needs to store the receiving userspace socket
when sending from the kernel to userspace. Rename 'ssk' to 'sk' to
avoid confusion.

netlink: Rename pid to portid to avoid confusion

2012-09-10T19:30:41+00:00

It is a frequent mistake to confuse the netlink port identifier with a
process identifier.  Try to reduce this confusion by renaming fields
that hold port identifiers portid instead of pid.

I have carefully avoided changing the structures exported to
userspace to avoid changing the userspace API.

I have successfully built an allyesconfig kernel with this change.

userns: Teach inet_diag to work with user namespaces

2012-08-15T04:55:20+00:00

Compute the user namespace of the socket that we are replying to
and translate the kuids of reported sockets into that user namespace.

net: make sock diag per-namespace

2012-07-17T05:31:34+00:00

Before this patch sock_diag works for init_net only and dumps
information about sockets from all namespaces.

This patch expands sock_diag for all name-spaces.
It creates a netlink kernel socket for each netns and filters
data during dumping.

v2: filter accoding with netns in all places
    remove an unused variable.

udp_diag: implement idiag_get_info for udp/udplite to get queue information

2012-04-26T00:43:01+00:00

When we use netlink to monitor queue information for udp socket,
idiag_rqueue and idiag_wqueue of inet_diag_msg are returned with 0.

Keep consistent with netstat, just return back allocated rmem/wmem size.

sock_diag: Generalize requests cookies managements

2011-12-16T18:48:27+00:00

The sk address is used as a cookie between dump/get_exact calls.
It will be required for unix socket sdumping, so move it from
inet_diag to sock_diag.
