Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec
Steffen Klassert says: ==================== pull request (net): ipsec 2015-03-16 1) Fix the network header offset in _decode_session6 when multiple IPv6 extension headers are present. From Hajime Tazaki. 2) Fix an interfamily tunnel crash. We set outer mode protocol too early and may dispatch to the wrong address family. Move the setting of the outer mode protocol behind the last accessing of the inner mode to fix the crash. 3) Most callers of xfrm_lookup() expect that dst_orig is released on error. But xfrm_lookup_route() may need dst_orig to handle certain error cases. So introduce a flag that tells what should be done in case of error. From Huaibin Wang. Please pull or let me know if there are problems. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
