2008-10-08netfilter: xtables: move extension arguments into compound structure (1/6)Jan Engelhardt1-10/+7
The function signatures for Xtables extensions have grown over time. It involves a lot of typing/replication, and also a bit of stack space even if they are not used. Realize an NFWS2008 idea and pack them into structs. The skb remains outside of the struct so gcc can continue to apply its optimizations. This patch does this for match extensions' match functions. A few ambiguities have also been addressed. The "offset" parameter for example has been renamed to "fragoff" (there are so many different offsets already) and "protoff" to "thoff" (there is more than just one protocol here, so clarify).

2008-10-08netfilter: xt_recent: IPv6 supportJan Engelhardt1-54/+246
This updates xt_recent to support the IPv6 address family. The new /proc/net/xt_recent directory must be used for this. The old proc interface can also be configured out. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-10-08netfilter: rename ipt_recent to xt_recentJan Engelhardt1-0/+502
Like with other modules (such as ipt_state), ipt_recent.h is changed to forward definitions to (IOW include) xt_recent.h, and xt_recent.c is changed to use the new constant names. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Patrick McHardy <kaber@trash.net>
