The changes for __libc_csu_{init,fini} are incorrect, only main should be
changed.
__libc_csu_{init,fini} must be in the PIE.

Jakub,

http://sources.redhat.com/ml/libc-hacker/2004-07/msg00031.html

The original version was coded by the PaX Team not Solar Designer or myself,
when Alexander Gabert was woking on this bug in gentoo's bugzilla system.

You were notified in detail by mail and giving a link back on Mon, 9 Feb 2004
and a second time which I do not have record of.

Please explain in a little detail why you assert the following, under which
causes is it incorrect.

(In reply to comment #1)
> The changes for __libc_csu_{init,fini} are incorrect, only main should be
> changed.
> __libc_csu_{init,fini} must be in the PIE.


Note: 
The hardened project has built well over 1000 packages with this patch and has
an upcomming release right around the corner. If I'm needing to have this patch
reverted or changed with csu_* I'll need to know why for justifcation.

__libc_csu_init or __libc_csu_fini simply must come from the same binary (or PIE)
as _start, anything can't work (just look what those functions do).
So there is no need to access them through .got when they are known to be local
to the PIE.
The main change has been fixed in CVS.
