Hello everyone, on old CPU the current situation looks like this:
l1tf:Mitigation: PTE Inversion; VMX: EPT disabled mds:Vulnerable: Clear CPU buffers attempted, no microcode; SMT disabled meltdown:Mitigation: PTI spec_store_bypass:Vulnerable spectre_v1:Mitigation: __user pointer sanitization spectre_v2:Mitigation: Full generic retpoline, STIBP: disabled, RSB filling There's no way to mitigate some issues without microcode and Intel doesn't provide new updates for old hardware. The Deep Dive document for MDS includes: "software sequences to overwrite buffers" but it goes back only to Nehalem. Are there any plans for software fixes especially for older CPUs? TIA, Z.
