Subject: [PATCH 0/4] Unifrom keyring support across architectures and functions
Date: Tue, 15 Feb 2022 20:39:37 +0100	[thread overview]
Message-ID: <cover.1644953683.git.msuchanek@suse.de> (raw)

While testing KEXEC_SIG on powerpc I noticed discrepancy in support for
different keyrings across architectures and between KEXEC_SIG and
MODULE_SIG. Fix this by enabling suport for the missing keyrings.

The latter two patches obviously conflict with the ongoing module code
cleanup. If they turn out desirable I will add them to the other series
dealing with KEXEC_SIG.

The arm patches can be merged independently.

Thanks

Michal

  Fix arm64 kexec forbidding kernels signed with keys in the secondary
    keyring to boot
  kexec, KEYS, arm64: Make use of platform keyring for signature
    verification
  kexec, KEYS, s390: Make use of built-in and secondary keyring for
    signature verification
  module, KEYS: Make use of platform keyring for signature verification
