Public bug reported:
[ Impact ]
* Revoke & rotate to new signing key
* Update revocations, which match the next Ubuntu shim 15.7
revocations. Specifically - revoke certs that were previously protected
with by-hash revocations, revoke lost/unused certificates.
* Start using advantage2021v1 and ubuntu2022v1 signing keys.
* This is a routine key rotation.
[ Test Plan ]
* Check that old shim/grub boot this kernel
* Check that the upcomming future shim/grub can boot this kernel
* Check that these kernels can do signed kexec into itself
[ Where problems could occur ]
* Kernels with this patch applied should be signed using ubuntu/4 pro/3
core/2 signing streams.
[ Other Info ]
* TPM PCR values and measurements will change when changing the signing key
** Affects: linux (Ubuntu)
Importance: Undecided
Status: Triaged
** Changed in: linux (Ubuntu)
