Subject: [PATCH 0/2] Preloaded revocation keys
Date: Wed, 30 Sep 2020 16:15:06 -0400
Message-ID: <20200930201508.35113-1-eric.snowberg@oracle.com> (raw)

The Secure Boot Forbidden Signature Database, dbx, contains a list of
now revoked signatures and keys previously approved to boot with UEFI
Secure Boot enabled.  Currently EFI_CERT_X509_SHA256_GUID and
EFI_CERT_SHA256_GUID can be preloaded (at build time) into the system
blacklist keyring.

Add the ability to also preload EFI_CERT_X509_GUID dbx entries.

This series can be applied on its own; however to use preloaded
revocation certificates, [1] should be applied first.
