Hi,
is there a VA range in userspace which is always safe for mmap() with fixed adr? (x86_64 mostly)
I.e. a VA range where mmap() or ld will never map memory.
likely, you can find it out by yourself using: cat /proc/self/maps | head there you can find where kernel maps the very first object. Then, IMO, all you need to do is preceed that address. Beware, IMHO, don't start with address 0 as you might screw NULL handler. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
