GhantaKrishnamurthy MohanKrishna c30b70deb5 tipc: implement socket diagnostics for AF_TIPC
This commit adds socket diagnostics capability for AF_TIPC in netlink
family NETLINK_SOCK_DIAG in a new kernel module (diag.ko).

The following are key design considerations:
- config TIPC_DIAG has default y, like INET_DIAG.
- only requests with flag NLM_F_DUMP is supported (dump all).
- tipc_sock_diag_req message is introduced to send filter parameters.
- the response attributes are of TLV, some nested.

To avoid exposing data structures between diag and tipc modules and
avoid code duplication, the following additions are required:
- export tipc_nl_sk_walk function to reuse socket iterator.
- export tipc_sk_fill_sock_diag to fill the tipc diag attributes.
- create a sock_diag response message in __tipc_add_sock_diag defined
  in diag.c and use the above exported tipc_sk_fill_sock_diag
  to fill response.

tristate "The TIPC Protocol"
depends on INET
---help---
The Transparent Inter Process Communication (TIPC) protocol is
specially designed for intra cluster communication. This protocol
originates from Ericsson where it has been used in carrier grade
cluster applications for many years.
For more information about TIPC, see http://tipc.sourceforge.net.
This protocol support is also available as a module ( = code which
can be inserted in and removed from the running kernel whenever you
want). The module will be called tipc. If you want to compile it
as a module, say M here and read <file:Documentation/kbuild/modules.txt>.
If in doubt, say N.

Saying Y here will enable support for running TIPC on
IP-over-InfiniBand devices.

default y
---help---
Support for TIPC socket monitoring interface used by ss tool.
If unsure, say Y.
