[IPV6]: Replace sk_buff ** with sk_buff * in input handlers

2007-10-15T19:50:28+00:00

With all the users of the double pointers removed from the IPv6 input path,
this patch converts all occurances of sk_buff ** to sk_buff * in IPv6 input
handlers.

[IPV6]: Uninline netfilter okfns

2007-10-15T19:26:36+00:00

Uninline netfilter okfns for those cases where gcc can generate tail-calls.

Before:
   text    data     bss     dec     hex filename
8994153 1016524  524652 10535329         a0c1a1 vmlinux

After:
   text    data     bss     dec     hex filename
8992761 1016524  524652 10533937         a0bc31 vmlinux
-------------------------------------------------------
  -1392

All cases have been verified to generate tail-calls with and without netfilter.

[NET]: Dynamically allocate the loopback device, part 1.

2007-10-10T23:52:14+00:00

This patch replaces all occurences to the static variable
loopback_dev to a pointer loopback_dev. That provides the
mindless, trivial, uninteressting change part for the dynamic
allocation for the loopback.

[NET]: Make packet reception network namespace safe

2007-10-10T23:49:08+00:00

This patch modifies every packet receive function
registered with dev_add_pack() to drop packets if they
are not from the initial network namespace.

This should ensure that the various network stacks do
not receive packets in a anything but the initial network
namespace until the code has been converted and is ready
for them.

[SK_BUFF]: unions of just one member don't get anything done, kill them

2007-04-26T05:26:20+00:00

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).

[SK_BUFF]: Introduce skb_network_header_len

2007-04-26T05:26:19+00:00

For the common sequence "skb->h.raw - skb->nh.raw", similar to skb->mac_len,
that is precalculated tho, don't think we need to bloat skb with one more
member, so just use this new helper, reducing the number of non-skbuff.h
references to the layer headers even more.

[SK_BUFF]: Introduce skb_transport_offset()

2007-04-26T05:25:16+00:00

For the quite common 'skb->h.raw - skb->data' sequence.

[SK_BUFF]: Introduce skb_reset_transport_header(skb)

2007-04-26T05:25:15+00:00

For the common, open coded 'skb->h.raw = skb->data' operation, so that we can
later turn skb->h.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 cases:

skb->h.raw = skb->data;
skb->h.raw = {skb_push|[__]skb_pull}()

The next ones will handle the slightly more "complex" cases.

[SK_BUFF]: Introduce ipv6_hdr(), remove skb->nh.ipv6h

2007-04-26T05:25:14+00:00

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}.
