1 | Hi, |
2 | |
3 | CPU bugs seem to be more and more common: |
4 | https://www.heise.de/security/meldung/Linux-Kernel-und-Distributionen-schuetzen-vor-Prozessorluecke-Foreshadow-L1TF-4137264.html |
5 | https://www.heise.de/security/meldung/Spectre-NG-Foreshadow-gefaehrdet-Intel-Prozessoren-4137209.html |
6 | (sorry, I only know of this german spoken references...) |
7 | |
8 | With Linux kernel 4.18.1 Linus has introduced a fix (aka workaround) |
9 | of the Foreshadow bug. |
10 | |
11 | Unfortunately compiling that kernel (as downloaded from |
12 | https://mirrors.edge.kernel.org/pub/linux/kernel/v4.x/ ) |
13 | |
14 | gives me this bug: |
15 | |
16 | |
17 | ... |
18 | AR arch/x86/lib/built-in.a |
19 | CC virt/lib/irqbypass.o |
20 | AR virt/lib/built-in.a |
21 | AR virt/built-in.a |
22 | GEN .version |
23 | CHK include/generated/compile.h |
24 | UPD include/generated/compile.h |
25 | CC init/version.o |
26 | AR init/built-in.a |
27 | AR built-in.a |
28 | LD vmlinux.o |
29 | MODPOST vmlinux.o |
30 | arch/x86/kvm/x86.o: In function `kvm_get_arch_capabilities': |
31 | x86.c:(.text+0xb2): undefined reference to `l1tf_vmx_mitigation' |
32 | make[1]: *** [Makefile:1010: vmlinux] Error 1 |
33 | make: *** [Makefile:273: __build_one_by_one] Error 2 |
34 | [1] 25144 exit 2 make clean all |
35 | |
36 | |
37 | I am alone or is this known (a quick search on startpage.com does not |
38 | give me any useful) or ... ? |
39 | Is there a way around it? |
40 | |
41 | Cheers! |
