how to inject memory bitflips for maximum damage?

I'm hoping there's someone here who has some knowledge on linux's
placement of objects in memory, or can point me to the right direction.

We have FAUmachine (a linux-based fault-injection VM) installed and
running on our research cluster, and can inject memory-bitflips in our
processes running on top of FAUmachine.

My question is -- how do I find out where to inject the bitflip for
maximum damage (or even any damage at all). I've done a bit of searching
on google but haven't come up with much.

If anyone has any insight on where linux holds its critical memory
structures, or where it places its running programs in physical memory,
could you please let me know? I may take a stab at reading the source of
FAUmachine if nobody has any ideas or has done it before.

Replies to bling at stanford dot edu would be greatly appreciated!

Thanks,

Ben
