The paper presented by Olaf Arkin (amongst other) points to some parts
of the linux code where this "vulnerability" exists. I think Alan Cox
is working on some patches for his tree. I wonder whether it's better
to null-pad ethernet packets or to fill them with random values
(possibly an overkill, but more resiliant against fingerprinting).
