Questions about skb->nfcache and somthing about netflter?
In kernel-2.4, the struct sk_buff has a member“nfcache", when should we use it? I find in kernel 2.6 this variable has been deleted. So how could we implement the same function?
What are the exactly mean about NFC_UNKNOWN,NFC_ALTERED in linux/netfilter.h and IP Cache bits such as NFC_IP_SRC NFC_IP_DST in the linux/netfilter_ipv4.h? Where could i find some papers introduce these in details!
thanks in advance!
