how to use sk_buff
Hi,all
i want to make some change on ip packet in NF_IP_PRE_ROUTING
hook. but i don't know what is the exactly means of each piece in
struct sk_buff.
i know how to generate a packet, but how to generate a correct
sk_buff of the packet is a difficult for me, and how to put the
sk_buff to the system is a problem too.
How? or where to get more details of that? is there a example
program to learn?
thx.
