unix_diag: Fixup RQLEN extension report

2011-12-30T21:46:02+00:00

While it's not too late fix the recently added RQLEN diag extension
to report rqlen and wqlen in the same way as TCP does.

I.e. for listening sockets the ack backlog length (which is the input
queue length for socket) in rqlen and the max ack backlog length in
wqlen, and what the CINQ/OUTQ ioctls do for established.

unix_diag: Include unix_diag.h into header-y target

2011-12-30T21:42:19+00:00

The headers check complains it should include the linux/types.h
withing, thus add this one.

unix_diag: Pending connections IDs NLA

2011-12-16T18:48:28+00:00

When establishing a unix connection on stream sockets the
server end receives an skb with socket in its receive queue.

Report who is waiting for these ends to be accepted for
listening sockets via NLA.

There's a lokcing issue with this -- the unix sk state lock is
required to access the peer, and it is taken under the listening
sk's queue lock. Strictly speaking the queue lock should be taken
inside the state lock, but since in this case these two sockets
are different it shouldn't lead to deadlock.

unix_diag: Unix peer inode NLA

2011-12-16T18:48:28+00:00

Report the peer socket inode ID as NLA. With this it's finally
possible to find out the other end of an interesting unix connection.

unix_diag: Unix inode info NLA

2011-12-16T18:48:28+00:00

Actually, the socket path if it's not anonymous doesn't give
a clue to which file the socket is bound to. Even if the path
is absolute, it can be unlinked and then new socket can be
bound to it.

With this NLA it's possible to check which file a particular
socket is really bound to.
