Netfilter in IPv4

[Xia Wei-Zhong-W20079 <xia@xxxxxxxxxxxx>]

Hi

Can any of you help me check if below piece of code is correct? And it does not violate any Linux conventions? 

static unsigned int hook_input(
 unsigned int hooknum,
    struct sk_buff **pskb,
    const struct net_device *in,
    const struct net_device *out,
    int (*okfn)(struct sk_buff *))
{
 
    ......................... 

    If(action == APPLY )
     {
            skb->dst->input(skb);
            result = NF_STOLEN;
     }

    ......................
}

This is a netfilter handler registered to NF_IP_LOCAL_IN. Because we need process the processed packet again, we use skb->dst->input(skb) to send it again, then it will be processed again by the callback. Is this correct?

Thanks, Xia Weizhong
