Dave Jones bd4ac46f66 Merge some improvements to the 32bit mmap randomisation from Kees Cook. 2011-09-19 16:44:51 -04:00
Dave Jones c62acbf43a Bring back the 32bit mmap randomization patch for now. 
NX emulation is still too dependant upon it.

Dave Jones fff25a2ad1 exec-randomization: brk away from exec rand area 
This is a fix for the NX emulation patch to force the brk area well
outside of the exec randomization area to avoid future allocation or brk
growth collisions. Normally this isn't a problem, except when the text
region has been loaded from a PIE binary and the CS limit can't be put
just above bss.

A test-case that will show failures without this patch can be found here:
