Hi folks,

A bugfix for SEV Live Migration was recently merged into the x86/sev
feature tree: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=ac3f9c9f1b37edaa7d1a9b908bc79d843955a1a2

Would we be able to get this bug fix backported into the Debian 12
kernel? The bug causes memory corruption on migration, and we are
unable to support SEV Live Migration on Debian without it.

Kind regards,
Ben Hillier

AFAICS this was back then marked for inclusion in stable and did land
in 6.1.53 upstream. So in the next weekends point release for bookworm
it will be included as we do rebase to 6.1.55.

Hi folks,

I wanted to inquire again about getting this bug fix merged into the
Debian stable kernel. I understand you're usually open to getting bug
fixes added to the stable kernel. Please let me know if you'll be able
to get this bug fix added to the Debian kernel. https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=ac3f9c9f1b37edaa7d1a9b908bc79d843955a1a2

Thank you,
Ben Hillier

See https://lists.debian.org/debian-kernel/2023/10/msg00038.html

And I have verified again, this is already included in upstream 6.1.53
upstream and so in Debian bookworm's kernel since 6.1.55-1.
