More Red Hat b0rkage?

[Mike Hearn]

I know Wine has some issues with some kernel security patches and memory
regions. Can anybody confirm that this won't cause issues:

The Red Hat Linux 9.0.93 kernel includes new Exec-shield functionality
Exec-shield is a security-enhancing modification to the Linux kernel
that makes large parts of programs — including their stack — not
executable. This can reduce the potential damage of some security holes.
Exec-shield is related to the older "non-exec stack patch" but has the
potential to provide much greater protection.

Exec-shield's behavior can be controlled via the proc file system. The
command used is:

echo <value> > /proc/sys/kernel/exec-shield

It will, but there's a 'chstk' tool (that hopefully RedHat is shipping
along with their kernel) that lets you set a flag in the Wine binary
to make it go back to normal stack behavior.
