This patch moves the setting of the IP length and checksum fields out of
the transforms and into the xfrmX_output functions. This would help future
efforts in merging the transforms themselves.It also adds an optimisation to ipcomp due to the fact that the transport
offset is guaranteed to be zero.Signed-off-by: Herbert Xu

The IPv6 calling convention for x->mode->output is more general and could
help an eventual protocol-generic x->type->output implementation. This
patch adopts it for IPv4 as well and modifies the IPv4 type output functions
accordingly.It also rewrites the IPv6 mac/transport header calculation to be based off
the network header where practical.Signed-off-by: Herbert Xu

This patch changes the calling convention so that on entry from
x->mode->output and before entry into x->type->output skb->data
will point to the payload instead of the IP header.This is essentially a redistribution of skb_push/skb_pull calls
with the aim of minimising them on the common path of tunnel +
ESP.It'll also let us use the same calling convention between IPv4
and IPv6 with the next patch.Signed-off-by: Herbert Xu

Renaming skb->h to skb->transport_header, skb->nh to skb->network_header and
skb->mac to skb->mac_header, to match the names of the associated helpers
(skb[_[re]set]_{transport,network,mac}_header).Signed-off-by: Arnaldo Carvalho de Melo

Now the skb->nh union has just one member, .raw, i.e. it is just like the
skb->mac union, strange, no? I'm just leaving it like that till the transport
layer is done with, when we'll rename skb->mac.raw to skb->mac_header (or
->mac_header_offset?), ditto for ->{h,nh}.Signed-off-by: Arnaldo Carvalho de Melo

skb_push updates and returns skb->data, so we can just call
skb_reset_network_header after the call to skb_push.Signed-off-by: Arnaldo Carvalho de Melo

For the common, open coded 'skb->nh.raw = skb->data' operation, so that we can
later turn skb->nh.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.This one touches just the most simple case, next will handle the slightly more
"complex" cases.Signed-off-by: Arnaldo Carvalho de Melo
Signed-off-by: David S. Miller -
For the places where we need a pointer to the mac header, it is still legal to
touch skb->mac.raw directly if just adding to, subtracting from or setting it
to another layer header.This one also converts some more cases to skb_reset_mac_header() that my
regex missed as it had no spaces before nor after '=', ugh.Signed-off-by: Arnaldo Carvalho de Melo

Please consider applying, this was found on your latest
net-2.6 tree while playing around with that ip_hdr() + turn
skb->nh/h/mac pointers as offsets on 64 bits idea :-)Signed-off-by: Arnaldo Carvalho de Melo

Expose IPSEC modes output path to take an xfrm state as input param.
This makes it consistent with the input mode processing (which already
takes the xfrm state as a param).Signed-off-by: Jamal Hadi Salim

This patch adds the structure xfrm_mode. It is meant to represent
the operations carried out by transport/tunnel modes.By doing this we allow additional encapsulation modes to be added
without clogging up the xfrm_input/xfrm_output paths.Candidate modes include 4-to-6 tunnel mode, 6-to-4 tunnel mode, and
BEET modes.Signed-off-by: Herbert Xu
