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 net/l2tp/l2tp_ppp.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+)
