In netem_enqueue function the value of skb_headlen(skb) can be zero which leads to a division error during randomized corruption of the packet. This fix adds a check to skb_headlen(skb) to prevent the division error.
Empty skbs are not sane. Is it just the fact that netlink_sendmsg() does not pay much attention to len that's the problem? Can we fix that instead?
