tipc: move and rename the legacy nl api to "nl compat"

2015-02-09T21:20:47+00:00

The new netlink API is no longer "v2" but rather the standard API and
the legacy API is now "nl compat". We split them into separate
start/stop and put them in different files in order to further
distinguish them.

tipc: make netlink support net namespace

2015-01-12T21:24:34+00:00

Currently tipc module only allows users sitting on "init_net" namespace
to configure it through netlink interface. But now almost each tipc
component is able to be aware of net namespace, so it's time to open
the permission for users residing in other namespaces, allowing them
to configure their own tipc stack instance through netlink interface.

tipc: involve namespace infrastructure

2015-01-12T21:24:32+00:00

Involve namespace infrastructure, make the "tipc_net_id" global
variable aware of per namespace, and rename it to "net_id". In
order that the conversion can be successfully done, an instance
of networking namespace must be passed to relevant functions,
allowing them to access the "net_id" variable of per namespace.
