Hello,

While "reading" the kernel sources referring to AF_INET SOCK_RAW
sockets, i have stumbled upon some particular issues:

* in raw_icmp_error. why is the marked line required?
 290                         raw_err(raw_sk, skb, info);
 291                         raw_sk = sk_next(raw_sk);
*292                         iph = (const struct iphdr *)skb->data; // <<<<<<
 293                 }
 294         }

looking over raw_err, the skb is not changed and i don't think that it
is meant to since that means delivering different thinks to different
sockets, while iterating. (i have tracked this line back to
2.4.3.2->2.4.3.3).

* also in raw_bind:
why is there no lock_sock/release_sock while changing socket
attributes (like in rawv6_bind)?

Thanks,
Bogdan B.
