Could you do a bisect on this? There seems to be one commit for this
particular function _decode_session6:

commit bafd4bd4dcfa13145db7f951251eef3e10f8c278

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?
