This is also included in shim builtin latest revocation, but it revokes shim binaries impacted by: * CVE-2023-40547 * CVE-2023-40546 * CVE-2023-40548 * CVE-2023-40549 * CVE-2023-40550 * CVE-2023-40551 And also revokes GRUB binaries impacted by: * CVE-2023-4692 * CVE-2023-4693
When the term previous was introduced for revocations to be automatically applied there was a hope that everytime a new revocation was built into shim, the previous revocation could be applied automatically. Further experience has shown the real world to be more complex than that. The automatic payload will realistically contain a set of revocations governed by both the cadence at which a distro's customer base updates as well as the severity of the issue being revoked. This is not a functional change. Signed-off-by: Jan Setje-Eilers <Jan.SetjeEilers@oracle.com>
With shim added as a git module this allows builds to specify revocations from SbatLevel_Variable.txt on the command line they currently default to: SBAT_LATEST_DATE=2023012950 SBAT_AUTOMATIC_DATE=2023012900 Signed-off-by: Jan Setje-Eilers <jan.setjeeilers@oracle.com>

I should probably add a way to build time select SkuSi as automatic or not and also build the separate with the right names. Will add that shortly. (done) |
Automatically build revocations_sbat.efi and revocations_sku.efi binaries that contain only sbat and SkuSi revocation payloads. Signed-off-by: Jan Setje-Eilers <Jan.SetjeEilers@oracle.com>
