2015-04-04netfilter: Create and use nf_hook_state.David S. Miller1-8/+3
Instead of passing a large number of arguments down into the nf_hook() entry points, create a structure which carries this state down through the hook processing layers. This makes is so that if we want to change the types or signatures of any of these pieces of state, there are less places that need to be changed. Signed-off-by: David S. Miller <davem@davemloft.net>
2013-10-19net: misc: Remove extern from function prototypesJoe Perches1-17/+11
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.

2012-09-03netfilter: pass 'nf_hook_ops' instead of 'list_head' to nf_queue()Michael Wang1-1/+1
Since 'list_for_each_continue_rcu' has already been replaced by 'list_for_each_entry_continue_rcu', pass 'list_head' to nf_queue() as a parameter can not benefit us any more. This patch will replace 'list_head' with 'nf_hook_ops' as the parameter of nf_queue() and __nf_queue() to save code.

2005-08-29[NETFILTER]: split net/core/netfilter.c into net/netfilter/*.cHarald Welte1-0/+39
