The ip_conntrack module makes an automatic defragmentation but I need modify the packets (padding bytes and change the ip protocol) and the conntrack have a rare behavior with TCP connections. The Netfilter Howto Documment (Netfilter Hooks For Tunnel Writers) it recommended to do: nf_conntrack_put(skb->nfct); skb->nfct = 0; But it don't resolves my problem, so I'm trying to avoid use ip_conntrack module cause I use it only for defragmentation. The point is: how I can do a manualy defragmentation in netfilter hook? The funtion ip_defrag return a NULL pointer if the packet is not complete and I don't know what do with the packet: I should enqueue it? How? I appreciate any help, Thanks. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
