Hi, CPU bugs seem to be more and more common: https://www.heise.de/security/meldung/Linux-Kernel-und-Distributionen-schuetzen-vor-Prozessorluecke-Foreshadow-L1TF-4137264.html https://www.heise.de/security/meldung/Spectre-NG-Foreshadow-gefaehrdet-Intel-Prozessoren-4137209.html (sorry, I only know of this german spoken references...)
With Linux kernel 4.18.1 Linus has introduced a fix (aka workaround) of the Foreshadow bug. Unfortunately compiling that kernel (as downloaded from https://mirrors.edge.kernel.org/pub/linux/kernel/v4.x/ ) gives me this bug: ... AR arch/x86/lib/built-in.a CC virt/lib/irqbypass.o AR virt/lib/built-in.a AR virt/built-in.a GEN .version CHK include/generated/compile.h UPD include/generated/compile.h CC init/version.o AR init/built-in.a AR built-in.a LD vmlinux.o MODPOST vmlinux.o arch/x86/kvm/x86.o: In function `kvm_get_arch_capabilities': x86.c:(.text+0xb2): undefined reference to `l1tf_vmx_mitigation' make[1]: *** [Makefile:1010: vmlinux] Error 1 make: *** [Makefile:273: __build_one_by_one] Error 2 [1] 25144 exit 2 make clean all I am alone or is this known (a quick search on startpage.com does not give me any useful) or ... ? Is there a way around it? Cheers! Meino
