BugLink: https://bugs.launchpad.net/bugs/1810807 commit 94d7ee0b upstream. The code following l2tp_tunnel_find() expects that a new reference is held on sk. Either sk_receive_skb() or the discard_put error path will drop a reference from the tunnel's socket. This issue exists in both l2tp_ip and l2tp_ip6. Fixes: a3c18422 ("l2tp: hold socket before dropping lock in l2tp_ip{, 6}_recv()") Signed-off-by:Guillaume Nault <g.nault@alphalink.fr> Signed-off-by:
