I've been able to transmit my packet.. no more kernel oops but it seems i'm having an alignment problem. Tcpdump tells me "ethertype unknown" on each packet that has been altered by my module. That packet originally comes from "ping", I do not generate it myself, so i guess the ethernet header, IP header, data are correct. It just seems I missed a point before dev_queue_xmit() my skb. I'm having the same problem if I skb_copy() instead of skb_clone() the original skb. Here is a summary of my code: hook_interrupt -> cloning skb to new_skb -> changing new_skb->dev to another interface -> dev_queue_xmit(new_skb); -> return NF_STOLEN for the original skb What am I missing? - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
