Results from Linaro’s test farm.
We are booting the i386 kernel on an x86 machine. With Spectre V2 patches merged into Linux mainline we have been noticing RETBleed: WARNING: Spectre v2 mitigation leaves CPU vulnerable to RETBleed attacks, data leaks possible!
That's funny. I don't think that's a valid combination that should be cared about, but I'll leave it to Pawan to comment if it is something that is "real" to be concerned for.
Yeah, so far nobody cared to fix 32bit. If someone *realllllly* cares and wants to put the effort in I suppose I'll review the patches, but seriously, you shouldn't be running 32bit kernels on Skylake / Zen based systems, that's just silly.
