Description of problem:

Hi.
I have a luks device already clevis-pined and when I try to 'regen':

-> clevis luks list -d /dev/nvme0n1p3
1: tpm2 '{"hash":"sha256","key":"rsa","pcr_bank":"sha256","pcr_ids":"0,1"}'
[root@dzien ~]# clevis luks regen -d /dev/nvme0n1p3 -s 1
Regenerating binding (device /dev/nvme0n1p3, slot 1):
Pin: tpm2, Config: '{"hash":"sha256","key":"rsa","pcr_bank":"sha256","pcr_ids":"0,1"}'
Do you want to proceed? [ynYN] y

It's a fresh install on AMD hardware, 'regen' needed for PCRs changed after PCI HW changes.

> ERROR: Unable to run tpm2_load

These items are part of the `tpm2-tools` package; I've recategorized this BZ appropriately.

Does this problem still persist?

I tried to reproduce it on a VM, but was unable to.

Changed the PCR and also cleared the TPM, but in both cases the regeneration was successful.

"authorizations for objects subject to DA protection are not allowed at this time because the TPM is in DA lockout mode"

It looks like the TPM on that system is locked out.

Comment 5 RHEL Program Management 2023-06-26 07:28:08 UTC
After evaluating this issue, there are no plans to address it further or fix it in an upcoming release.  Therefore, it is being closed.  If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.
