Subject: [NET][IA64] Unaligned access in sk_run_filter
Date: Mon, 20 Feb 2006 18:28:28 +0300 [thread overview]
Message-ID: <200602201828.29098.dim@openvz.org> (raw)
Hello,
We have an issue on ia64 box. It is easy triggerable 'kernel unaligned access'
in sk_run_filter:
ptr = load_pointer(skb, k, 4, &tmp);
if (ptr != NULL) {
A = ntohl(*(u32 *)ptr); << here
continue;
}
due to 'k' is coming from userspace it can be easy triggered, e.g.:
[root@node1 ~]# tcpdump -i eth0 'ip[1:2]=0'
Could you advise how to fix this?

Thanks,
Dmitry.
