From 62fc8051083a334578c3f4b3488808f210b4565f Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Tue, 7 Jul 2009 20:42:08 +0200 Subject: 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).
