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.
