Hello Patric - No particular application but as an available security feature, albeit not the panacea the masses thought it would be when released, I was just curious how it potentially worked (or didn't work) with the Intel processors using amd64. I can say in the environments I've been in, NX never stopped anything, just slightly mitigated the damage done (and even that was debatable). I would have to assume that with the stability and maturity I've come to find in OpenBSD W^X may never come in to play or ever be needed.

To keep it simple, I'm looking at installing OpenBSD on a ThinkPad T61p w/Intel Core 2 Duo. I've been reading that the amd64 platform will work however the NX bit isn't supported. Intel has since come out with their own version of the NX bit for whatever reason (shouldn't they have just copied it like they did everything else?), the XD bit. Has this been implemented anywhere so that the amd64-bit platform, running under an Intel proc, will support W^X? If not it looks like I should stick with 32-bit... and if not, any plans in the future on implementing Intel's specific XD bit? Thanks, Brian Drain -- Some software money can't buy. For everything else there's Micros~1.
