Hi folks, I want to register a new Hook in the netfilter (from kernel 2.4.4) canvas for IP. The struct used for register is : struct nf_hook_ops { struct list_head list; /* User fills in from here down. */ nf_hookfn *hook; int pf; int hooknum; /* Hooks are ordered in ascending priority. */ int priority; }; And the hook function is a nf_hookfn, which is a typedef : typedef unsigned int nf_hookfn(unsigned int hooknum, struct sk_buff **skb, const struct net_device *in, const struct net_device *out, int (*okfn)(struct sk_buff *)); What is the parameter int (*okfn)(struct sk_buff *) which is passed to the hook ? Thanx for the answers !!! - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
