PIE randomization
This patch is using mmap()'s randomization functionality in such a way that it maps the main executable of (specially compiled/linked -pie/-fpie) ET_DYN binaries onto a random address (in cases in which mmap() is allowed to perform a randomization). Origin of this patch is in exec-shield (http://people.redhat.com/mingo/exec-shield/) [jkosina@suse.cz: pie randomization: fix BAD_ADDR macro] Signed-off-by: Jan Kratochvil <honza@jikos.cz> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Cc: Ingo Molnar <mingo@elte.hu> Cc: Roland McGrath <roland@redhat.com> Cc: Jakub Jelinek <jakub@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
