Meltdown & Spectre Information and Discussion

[Moltke]

It seems the new kernel 4.13.33 fixes the variant 2 version on an older amd at least.

I'm using latest kernel 4.15 on an AMD CPU too and I see this message on boot I can't just now remember. However, running

Code:

$ grep . /sys/devices/system/cpu/vulnerabilities/*

shows this:

Code:

/sys/devices/system/cpu/vulnerabilities/meltdown:Not affected
/sys/devices/system/cpu/vulnerabilities/spectre_v1:Vulnerable
/sys/devices/system/cpu/vulnerabilities/spectre_v2:Mitigation: Full generic retpoline

I believe message on boot has something to do with last line of that output; full generic reptoline.
