Hello again. I tested the issue in different examples: 1- When using NF_REPEAT with only 1 queue, there isnt any problem $IPTABLES -A OUTPUT -m state --state NEW -m mark ! --mark 1 -j NF_QUEUE 0 $IPTABLES -A OUTPUT -j ACCEPT 2- When using NF_REPEAT with (program 1 in queue 0 and program 2 in queue 1) $IPTABLES -A OUTPUT -m state --state NEW -m mark ! --mark 1 -j NF_QUEUE 0 $IPTABLES -A OUTPUT -m state --state NEW -m mark --mark 1 -j NF_QUEUE 1 then i got kernel panic. I think the problem is that using nfq_set_verdict_mark(myQueue, id, NF_REPEAT, htonl(1) ,0, NULL) don't modify packet length and kernel freezes, but im not sure, im newbie please help me. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
