f65c1b534b sock_diag: Generalize requests cookies managements
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.

1942c518ca inet_diag: Generalize inet_diag dump and get_exact calls
Introduce two callbacks in inet_diag_handler -- one for dumping all
sockets (with filters) and the other one for dumping a single sk.

Replace direct calls to icsk handlers with indirect calls to callbacks
provided by handlers.

Make existing TCP and DCCP handlers use provided helpers for icsk-s.

The UDP diag module will provide its own.

3c4d05c805 inet_diag: Introduce the inet socket dumping routine
The existing inet_csk_diag_fill dumps the inet connection sock info
into the netlink inet_diag_message. Prepare this routine to be able
to dump only the inet_sock part of a socket if the icsk part is missing.

This will be used by UDP diag module when dumping UDP sockets.

b005ab4ef8 inet_diag: Export inet diag cookie checking routine
The netlink diag susbsys stores sk address bits in the nl message
as a "cookie" and uses one when dumps details about particular
socket.

The same will be required for udp diag module, so introduce a heler
in inet_diag module

7b35eadd7e inet_diag: Remove indirect sizeof from inet diag handlers
There's an info_size value stored on inet_diag_handler, but for existing
code this value is effectively constant, so just use sizeof(struct tcp_info)
where required.

06236ac372 net-netlink: Add a new attribute to expose TCLASS values via netlink
commit 3ceca74966 added a TOS attribute.

Unfortunately TOS and TCLASS are both present in a dual-stack v6 socket,
furthermore they can have different values.  As such one cannot in a
sane way expose both through a single attribute.

3ceca74966 net-netlink: Add a new attribute to expose TOS values via netlink
This patch exposes the tos value for the TCP sockets when the TOS flag
is requested in the ext_flags for the inet_diag request. This would mainly be
used to expose TOS values for both for TCP and UDP sockets. Currently it is
supported for TCP. When netlink support for UDP would be added the support
to expose the TOS values would alse be done. For IPV4 tos value is exposed
and for IPV6 tclass value is exposed.
