There's a strange sky2 bug on the Gentoo bugzilla:
http://bugs.gentoo.org/show_bug.cgi?id=136508
sky2 seems to work OK, but breaks as soon as the iptables ruleset is
loaded. Nothing can be pinged, etc.
Can someone try and reproduce this? The iptables rule script has been
uploaded here:
http://bugs.gentoo.org/attachment.cgi?id=95694&action=view
The very last command in that file is the one which produces an error
and stops everything working:
iptables: Unknown error 18446744073709551615
Apparently a sky2 null deref has also been seen at this point, although
I don't have further details on that.
It might be an artifact of the way sky2 was allocating receive buffers.
Bridge-netfilter was assuming header space in the buffer, and would corrupt
other memory, maybe iptables is assuming as well. This makes sky2
use dev_alloc_skb that reserves space.

Unfortunately the problem still exists with this patch. Any other ideas?
