netfilter: utils: move nf_ip_checksum* from ipv4 to utils

2018-07-16T15:51:48+00:00

allows to make nf_ip_checksum_partial static, it no longer
has an external caller.

netfilter: move reroute indirection to struct nf_ipv6_ops

2018-01-08T17:10:53+00:00

We cannot make a direct call to nf_ip6_reroute() because that would result
in autoloading the 'ipv6' module because of symbol dependencies.
Therefore, define reroute indirection in nf_ipv6_ops where this really
belongs to.

For IPv4, we can indeed make a direct function call, which is faster,
given IPv4 is built-in in the networking code by default. Still,
CONFIG_INET=n and CONFIG_NETFILTER=y is possible, so define empty inline
stub for IPv4 in such case.

netfilter: move route indirection to struct nf_ipv6_ops

We cannot make a direct call to nf_ip6_route() because that would result
in autoloading the 'ipv6' module because of symbol dependencies.
Therefore, define route indirection in nf_ipv6_ops where this really
belongs to.

netfilter: remove saveroute indirection in struct nf_afinfo

2018-01-08T17:01:25+00:00

This is only used by nf_queue.c and this function comes with no symbol
dependencies with IPv6, it just refers to structure layouts. Therefore,
we can replace it by a direct function call from where it belongs.

ipv4: Pass struct net into ip_route_me_harder

2015-09-29T18:21:32+00:00

Don't make ip_route_me_harder guess which network namespace
it is routing in, pass the network namespace in.

netfilter: Remove extern from function prototypes

2013-09-26T21:48:15+00:00

There are a mix of function prototypes with and without extern
in the kernel sources.  Standardize on not using extern for
function prototypes.

Function prototypes don't need to be written with extern.
extern is assumed by the compiler.  Its use is as unnecessary as
using auto to declare automatic/local variables in a block.
