cls_u32: use skb_header_pointer() to dereference data safely use skb_header_pointer() to dereference data safely the original skb->data dereference isn't safe, as there isn't any skb->len or skb_is_nonlinear() check. skb_header_pointer() is used instead in this patch. And when the skb isn't long enough, we terminate the function u32_classify() immediately with -1. Signed-off-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
