Boot with "nopti" kernel option.
Is there any way to create like a live CD that could run the checks regardless of the installed OS? On my machine with the older 3.16 kernel, it showed not vulnerable, but is that the case or is it because the kernel was too old for the check to work properly? Further, something that can do some simple benchmarks to see how much the fixes will slow them down.
AFAIK, what the test does is look if the kernel has been patched, not really test for the vulnerability.
No, not from what I've seen. If you run it on a non-vulnerable CPU with an unpatched kernel, it reports as non-vulnerable because the exploit fails. I have tested both ways, on both vulnerable and non-vulnerable CPU's. -- ============================================================== Rodney Baker VK5ZTV rodney.baker@iinet.net.au CCNA #CSCO12880208 ============================================================== -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
