Hi all !

I am beginber about netfilter.
At skbuff.h
.....
#ifdef CONFIG_NETFILTER
	/* Can be used for communication between hooks. */
        unsigned long	nfmark;
	/* Cache info */
	__u32		nfcache;
	/* Associated connection, if any */
	struct nf_ct_info *nfct;

Can anyone explain to me that what those value nfmark,nfcache and nfct mean
Thanks in advance
