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
