First there is BUG from ipv6 code, followed by panic. Could you do a bisect on this? There seems to be one commit for this particular function _decode_session6: commit bafd4bd4dcfa13145db7f951251eef3e10f8c278 Author: Steffen Klassert Date: Mon Sep 9 10:38:38 2013 +0200 xfrm: Decode sessions with output interface. The output interface matching does not work on forward policy lookups, the output interface of the flowi is always 0. Fix this by setting the output interface when we decode the session. Maybe try to just revert this change locally and try again?
