Or is there something wrong with:
- packet arrives in net/ipv4/ip_input.c:ip_rcv()
- netfilter hook NF_IP_PRE_ROUTING is called
- net/ipv4/netfilter/ip_conntrack_core.c:ip_conntrack_in() is called
- net/ipv4/netfilter/ip_conntrack_core.c:ip_ct_gather_frags() is called
- net/ipv4/ip_input.c:ip_defrag() is called
Isn't the skb->dev member supposed to still point to the receiving
device?
No, once you submit the packet to the defrag layer, that SKB
instance is owned by the defrag layer.
One way to do what netfilter wants to do, but legally, is to
simply skb_clone() the SKB before passing it into the
defragmentation code.
I'm still deciding whether this is the best fix.
