Subject: [PATCH 0/4] l2tp: fix up network namespace use in l2tp_core

This patchset addresses network namespace issues in l2tp_core as previously
raised on netdev[1].

There is further work to be done to bring namespace support to the rest of
l2tp -- this will be addressed in a further patchset.

I've tested these changes using a stress script based around iproute2's netns
command.  Test platforms include i386, x86_64, and armv6l, running on
single-core and SMP platforms, and with/without preemption enabled.

Tom Parkin (4):
  l2tp: set netnsok flag for netlink messages
  l2tp: prevent tunnel creation on netns mismatch
  l2tp: don't pin network namespaces with tunnel sockets
  l2tp: clear tunnel socket field as soon as we release it
