xfrm: fix xfrm by MARK logic
While using xfrm by MARK feature in 2.6.34 - 2.6.35 kernels, the mark is always cleared in flowi structure via memset in _decode_session4 (net/ipv4/xfrm4_policy.c), so the policy lookup fails. IPv6 code is affected by this bug too. Signed-off-by: Peter Kosyh <p.kosyh@gmail.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
