Hi list,
I'm having trouble about NF_HOOK()
call.
I intent to add a netfilter hook with
nf_register_hook.
THe hook point is NF_ARP_IN. But I'm not sure the
caller's context.
In kernel code, dev.c I found the
caller:
netif_receive_skb -> arp_rcv -> NF_HOOK
-> my_hook_cb
When my_hook_cb is invoked, what's the
context? And how can I detect it?
Any idea? Thanks in advance.
Regards~
