Hello,
This patch series implements per-boot kernel base offset ASLR. It is based
on work by Dan Rosenberg, Neill Clift, Michael Davidson, and myself. Since
Dan's original thread[1], this code has been improved to work on 64-bit,
among other things.
This is presently in use at Google, and is being ported to Chrome
OS. It has several limitations currently, but I wanted to get the ball
rolling again on upstreaming this. More details are in the individual
patches. They are split into three pieces: the offset selection logic,
the 64-bit relocation logic, and finally putting the offset to use at
boot time.
Thanks,
-Kees
