ipv4: xfrm: Eliminate ->rt_src reference in policy code.

2011-05-10T20:32:48+00:00

Rearrange xfrm4_dst_lookup() so that it works by calling a helper
function __xfrm_dst_lookup() that takes an explicit flow key storage
area as an argument.

Use this new helper in xfrm4_get_saddr() so we can fetch the selected
source address from the flow instead of from rt->rt_src

ipv4: Renamt struct rtable's rt_tos to rt_key_tos.

2011-05-04T02:45:15+00:00

To more accurately reflect that it is purely a routing
cache lookup key and is used in no other context.

inet: constify ip headers and in6_addr

2011-04-22T18:04:14+00:00

Add const qualifiers to structs iphdr, ipv6hdr and in6_addr pointers
where possible, to make code intention more obvious.

ipv4: Fix "Set rt->rt_iif more sanely on output routes."

2011-04-07T21:04:08+00:00

Commit 1018b5c01636c7c6bda31a719bda34fc631db29a ("Set rt->rt_iif more
sanely on output routes.")  breaks rt_is_{output,input}_route.

This became the cause to return "IP_PKTINFO's ->ipi_ifindex == 0".

To fix it, this does:

1) Add "int rt_route_iif;" to struct rtable

2) For input routes, always set rt_route_iif to same value as rt_iif

3) For output routes, always set rt_route_iif to zero.  Set rt_iif
   as it is done currently.

4) Change rt_is_{output,input}_route() to test rt_route_iif

net: Make flowi ports AF dependent.

2011-03-12T23:08:46+00:00

Create two sets of port member accessors, one set prefixed by fl4_*
and the other prefixed by fl6_*

This will let us to create AF optimal flow instances.

It will work because every context in which we access the ports,
we have to be fully aware of which AF the flowi is anyways.

net: Put flowi_* prefix on AF independent members of struct flowi

2011-03-12T23:08:44+00:00

I intend to turn struct flowi into a union of AF specific flowi
structs.  There will be a common structure that each variant includes
first, much like struct sock_common.

This is the first step to move in that direction.

ipv4: Remove flowi from struct rtable.

2011-03-05T05:55:31+00:00

The only necessary parts are the src/dst addresses, the
interface indexes, the TOS, and the mark.

The rest is unnecessary bloat, which amounts to nearly
50 bytes on 64-bit.
