Alexey Dobriyan 68c11e98ef xfrm: fix xfrm_input/xfrm_tunnel_check oops ... https://bugzilla.kernel.org/show_bug.cgi?id=95211 Commit 70be6c91c8 ("xfrm: Add xfrm_tunnel_skb_cb to the skb common buffer") added check which dereferences ->outer_mode too early but larval SAs don't have this pointer set (yet). So check for tunnel stuff later. Mike Noordermeer reported this bug and patiently applied all the debugging. Technically this is remote-oops-in-interrupt-context type of thing.
