Hi, I'm currently developing a routing protocol and I used netfilter (ipv4) for that. I placed a function on local_out hook and my routing protocol has to add some data to some incoming skbuff. Sometimes, i received skbuff with a size of the net device mtu, and so i must do some ip fragmentation after adding data for my protocol. My pb is that skbuffs seem to arrive at local_out hook already fragmented, with an IP_DF flags set to 1 and IP_MF flags set to 0. I tried to dump any skbuff passing through local_out hook without altering them to see this fact. I tried sending packet with a ping -s 2000 for example. Is there a way to have non-fragmented skbuff with netfilter ? Because i want to handle fragmentation with my protocol... Thx in advance N. Plessis PS: sorry for my bad english...
