Hallo together!
Sorry, i speak only bad english, better only a few words. I hope you can understand me.
Presumably since mainline-kernel 4.16.7, current 4.16.8 is in /boot/retpoline-4.16.8-041608-config no order more, what will be do retpoline agains spectre_v2 attack. The file is absolutly blank. Under mainline-kernel 4.16.6 was this not so.
My question is now, how protect the mainline-kernel 4.16.8 agains spectre_v2 with retpoline? And especially without exact order, what to do.
For the others installed kernel are the exact order for example in /boot/retpoline-4.13-xxx-config with the content:
PHP Code:
arch/x86/platform/efi/efi_stub_64.S .text efi_call callq *%rdi
arch/x86/platform/efi/efi_thunk_64.S .text efi64_thunk callq *%rbx
arch/x86/platform/efi/efi_thunk_64.S .text efi_enter32 callq *%rdi
drivers/watchdog/hpwdt.c .text asminline_call callq *%r12
I think, without exact order what should do retpoline agains a spectre_v2 attack, is retpoline in kernel senceless.
I have copy the content from /boot/retpoline-4.13-xxxx-config in /boot/retpoline_4.16.8-xxxx-config.
But I don't no, is this right so. I think yes, but I don't no. Can somebody help me perhaps?
Thank You, very much!
