This appears to be OK on my CPU but want to ask to be sure. Here's some info, sort of taking cues from what you posted above. root@fireball / # uname -a Linux fireball 4.18.12-gentoo #1 SMP PREEMPT Sun Oct 14 23:45:12 CDT 2018 x86_64 AMD FX(tm)-8350 Eight-Core Processor AuthenticAMD GNU/Linux root@fireball / # cat /sys/devices/system/cpu/vulnerabilities/ l1tf meltdown spec_store_bypass spectre_v1 spectre_v2 root@fireball / # cat /sys/devices/system/cpu/vulnerabilities/meltdown Not affected root@fireball / # cat /sys/devices/system/cpu/vulnerabilities/l1tf Not affected root@fireball / # cat /sys/devices/system/cpu/vulnerabilities/spec_store_bypass Mitigation: Speculative Store Bypass disabled via prctl and seccomp root@fireball / # cat /sys/devices/system/cpu/vulnerabilities/spectre_v1 Mitigation: __user pointer sanitization root@fireball / # cat /sys/devices/system/cpu/vulnerabilities/spectre_v2 Mitigation: Full AMD retpoline root@fireball / # Am I correct to think that "Mitigation" is good enough or does that mean it could be affected in some other way or is risky? Also, since the problem that this thread is about isn't listed, mine isn't affected correct? I'm guessing "Not affected" means all is good. ;-) Thanks much. Just want to be sure my system is safe. Dale :-) :-)
