netfilter: ecache: always set events bits, filter them later
For the following rule: iptables -I PREROUTING -t raw -j CT --ctevents assured The event delivered looks like the following: [UPDATE] tcp 6 src=192.168.0.2 dst=192.168.1.2 sport=37041 dport=80 src=192.168.1.2 dst=192.168.1.100 sport=80 dport=37041 [ASSURED] Note that the TCP protocol state is not included. For that reason the CT event filtering is not very useful for conntrackd. To resolve this issue, instead of conditionally setting the CT events bits based on the ctmask, we always set them and perform the filtering in the late stage, just before the delivery. Thus, the event delivered looks like the following: [UPDATE] tcp 6 432000 ESTABLISHED src=192.168.0.2 dst=192.168.1.2 sport=37041 dport=80 src=192.168.1.2 dst=192.168.1.100 sport=80 dport=37041 [ASSURED] Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Patrick McHardy <kaber@trash.net>
