Subject: [PATCH net 0/4] l2tp: pppol2tp_connect() fixes

This series fixes a few remaining issues with pppol2tp_connect().

It doesn't try to prevent invalid configurations that have no effect on
kernel's reliability. That would be work for a future patch set.

Patch 2 is the most important as it avoids an invalid pointer
dereference crashing the kernel. It depends on patch 1 for correctly
identifying L2TP session types.

Patches 3 and 4 avoid creating stale tunnels and sessions.

Guillaume Nault (4):
  l2tp: fix pseudo-wire type for sessions created by pppol2tp_connect()
  l2tp: only accept PPP sessions in pppol2tp_connect()
  l2tp: prevent pppol2tp_connect() from creating kernel sockets
  l2tp: clean up stale tunnel or session in pppol2tp_connect's error
    path
