[XFRM]: Fix potential race vs xfrm_state(only)_find and xfrm_hash_resize. The _find calls calculate the hash value using the xfrm_state_hmask, without the xfrm_state_lock. But the value of this mask can change in the _resize call under the state_lock, so we risk to fail in finding the desired entry in hash. I think, that the hash value is better to calculate under the state lock. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
