NAME

6       sk_run_filter - run a filter on a socket
7

SYNOPSIS

9       unsigned int sk_run_filter(const struct sk_buff * skb,
10                                  const struct sock_filter * fentry);
11

ARGUMENTS

13       skb
14           buffer to run the filter on
15
16       fentry
17           filter to apply
18

DESCRIPTION

20       Decode and apply filter instructions to the skb->data. Return length to
21       keep, 0 for none.  skb is the data we are filtering, filter is the
22       array of filter instructions. Because all jumps are guaranteed to be
23       before last instruction, and last instruction guaranteed to be a RET,
24       we dont need to check flen. (We used to pass to this function the
25       length of filter)
