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.
