Subject: Defragmentation in Netfilter Hook
Date: Thu, 12 Jun 2008 05:25:22 -0700 (PDT)	[thread overview]
Message-ID: <278184.19561.qm@web33201.mail.mud.yahoo.com> (raw)

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.
