Subject: [PATCH 4/8] netfilter: xtables: combine struct xt_match_param and
 xt_target_param

The structures carried - besides match/target - almost the same data.
It is possible to combine them, as extensions are evaluated serially,
and so, the callers end up a little smaller.

From 62fc8051083a334578c3f4b3488808f210b4565f Mon Sep 17 00:00:00 2001
From: Jan Engelhardt <jengelh@medozas.de>
Date: Tue, 7 Jul 2009 20:42:08 +0200
Subject: [PATCH 6/8] netfilter: xtables: deconstify struct xt_action_param for
 matches

In future, layer-3 matches will be an xt module of their own, and
need to set the fragoff and thoff fields. Adding more pointers would
needlessy increase memory requirements (esp. so for 64-bit, where
pointers are wider).

From b4ba26119b06052888696491f614201817491a0d Mon Sep 17 00:00:00 2001
From: Jan Engelhardt <jengelh@medozas.de>
Date: Tue, 7 Jul 2009 20:54:30 +0200
Subject: [PATCH 7/8] netfilter: xtables: change hotdrop pointer to direct
 modification

Since xt_action_param is writable, let's use it. The pointer to
'bool hotdrop' always worried (8 bytes (64-bit) to write 1 byte!).
Surprisingly results in a reduction in size:

   text    data     bss filename
5457066  692730  357892 vmlinux.o-prev
5456554  692730  357892 vmlinux.o

From 4538506be386f9736b83bf9892f829adbbb70fea Mon Sep 17 00:00:00 2001
From: Jan Engelhardt <jengelh@medozas.de>
Date: Sat, 4 Jul 2009 12:50:00 +0200
Subject: [PATCH 8/8] netfilter: xtables: combine built-in extension structs

Prepare the arrays for use with the multiregister function. The
future layer-3 xt matches can then be easily added to it without
needing more (un)register code.

Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
