Hi, I was looking at the ICMP message sending code in ipip.c and it uses following prototype for icmp_send(struct sk_buff*. void*). I had a few questions in mind regarding this method: Before calling this method obviously one is supposed to allocate memory for sk_buff structure and I think that alloc_skb() does it...is that correct? Also, the sk_buff structure is more of a collection of pointers ... so when you do alloc_skb do u have allocate some memory pointed to by these pointers ? I am operating in the netfilter hook in the NF_IP_FORWARD stage. Any help will be appreciated!
