From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Jan Setje-Eilers <jan.setjeeilers@oracle.com>
Date: Thu, 21 Apr 2022 17:28:07 -0700
Subject: [PATCH] SBAT revocation update support
Control how shim will apply SBAT revocations:
mokutil --set-sbat-policy latest
applies the latest SBAT revocations
(default behavior)
mokutil --set-sbat-policy previous
applies previous SBAT revocations to
allow falling back to an older release
In both of the above cases shim will only apply SBAT revocations that
are newer than the ones currently installed.
mokutil --set-sbat-policy delete
resets SBAT revocations only if Secure
Boot is disabled. This setting does not
persist.

+Set the SbatPolicy UEFI Variable to have shim apply either the latest
+or the previous SBAT revocations. If UEFI Secure Boot is disabled, then
+delete will reset the SBAT revocations to an empty revocation list.
+While latest and previous are persistent configuration, delete will be
+cleared by shim on the next boot whether or not it succeeds. The default
+behavior is for shim to apply the previous revocations.
