Subject: [PATCH 0/3] KEXEC_SIG with appended signature
Date: Wed,  3 Nov 2021 15:27:05 +0100	[thread overview]
Message-ID: <cover.1635948742.git.msuchanek@suse.de> (raw)

S390 uses appended signature for kernel but implements the check
separately from module loader.

Support for secure boot on powerpc with appended signature is planned -
grub patches submitted upstream but not yet merged.

This is an attempt at unified appended signature verification.

Thanks

Michal

Michal Suchanek (3):
  s390/kexec_file: Don't opencode appended signature verification.
  module: strip the signature marker in the verification function.
  powerpc/kexec_file: Add KEXEC_SIG support.
