Herbert Xu 752c1f4c78 [IPSEC]: Kill post_input hook and do NAT-T in esp_input directly ... The only reason post_input exists at all is that it gives us the potential to adjust the checksums incrementally in future which we ought to do. However, after thinking about it for a bit we can adjust the checksums without using this post_input stuff at all. The crucial point is that only the inner-most NAT-T SA needs to be considered when adjusting checksums. What's more, the checksum adjustment comes down to a single u32 due to the linearity of IP checksums. We just happen to have a spare u32 lying around in our skb structure :) When ip_summed is set to CHECKSUM_NONE on input, the value of skb->csum is currently unused. All we have to do is to make that the checksum adjustment and voila, there goes all the post_input and decap structures! I've left in the decap data structures for now since it's intricately woven into the sec_path stuff. We can kill them later too.
