NAME
       sk_attach_filter - attach a socket filter

SYNOPSIS
       int sk_attach_filter(struct sock_fprog * fprog, struct sock * sk);

ARGUMENTS
       fprog
           the filter program

       sk
           the socket to use

DESCRIPTION
       Attach the user's filter code. We first run some sanity checks on it to make sure it does
       not explode on us later. If an error occurs or there is insufficient memory for the filter
       a negative errno code is returned. On success the return is zero.
