Hello,
Le mercredi 30 novembre 2011 à 08:58 +0100, U.Mutlu a écrit :
nfq_set_verdict() or nfq_set_verdict2():
NF_DROP discard the packet
NF_ACCEPT the packet passes, continue iterations
In my callback I pass NF_ACCEPT to let the packet continue its travel
through the subsequent rules (normal iptables rules).
When NF_ACCEPT is issued, the packet is accepted for the current table.
It will then only be checked by rules in other tables.
I need to just inspect the hdrs and then let it continue its usual way.
What is needed to realize this functionality?
Figuring out a way what to do with the packet if the ruleset changes
while the packet is out in userspace for an indefinite time.
Sorry, Jan, I don't get it. Why do you say the ruleset changes, it doesn't IMO.
I must be missing some important API-information I guess, if even such
a simple thing like reading the payload hdrs is not possible
w/o disturbing the normal flow.
I tried also NF_QUEUE, but the net result is the same like NF_ACCEPT, not what I need.
I need a simple "NF_RETURN", but that is undefined...
