skb->sk->state netfilter hooks

[Bhavpreet Singh <bhavpreet@xxxxxxxxx>]

Hi all,

i want to do something like this:

------------snip--------------
unsigned int hook_func(unsigned int hooknum,
                      struct sk_buff **skb,
                      const struct net_device *in,
                      const struct net_device *out,
                      int (*okfn)(struct sk_buff *))
{
 struct sk_buff *skb_temp;
 skb_temp = *skb;
 printk("%c", skb_temp->sk->state);


 return NF_ACCEPT;
}
----------snip-----------------


i am using netfilter hooks, and i get compilation error at the printk 
statement

---------error-----------
dereferencing pointer to incomplete type
---------error------------


Than-X in advance
