[IPSEC]: Move integrity stat collection into xfrm_input
Similar to the moving out of the replay processing on the output, this patch moves the integrity stat collectin from x->type->input into xfrm_input. This would eventually allow transforms such as AH/ESP to be lockless. The error value EBADMSG (currently unused in the crypto layer) is used to indicate a failed integrity check. In future this error can be directly returned by the crypto layer once we switch to aead algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
