SK_FILTER(9)		       Linux Networking			  SK_FILTER(9)

NAME
       sk_filter - run a packet through a socket filter

SYNOPSIS
       int sk_filter(struct sock * sk, struct sk_buff * skb);

ARGUMENTS
       sk
	   sock associated with sk_buff

       skb
	   buffer to filter

DESCRIPTION
       Run the filter code and then cut skb->data to correct size returned by
       sk_run_filter. If pkt_len is 0 we toss packet. If skb->len is smaller
       than pkt_len we keep whole skb->data. This is the socket level wrapper
       to sk_run_filter. It returns 0 if the packet should be accepted or
       -EPERM if the packet should be tossed.
