About matching

[Wang Jian <lark@linux.net.cn>]

Hi,

I haven't looked into code on how these two rules are evaluated


iptables <match rule 1> -j CONNMARK --set-mark value/mask
iptables <match rule 1> -j RETURN


How many times the match rule 1 is evaluated when matched? If two, then
the second time is waste of CPU cycle.

Then think these three

iptables <match rule 1> -j CONNMARK --set-mark value/mask
iptables <match rule 1> -j CONNMARK --restore --mask mask
iptables <match rule 1> -j RETURN

Are there any optimization for such case?
