RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Colin Walters 2021-08-03 00:07:20 UTC 
We're working on a C9S CoreOS (https://github.com/openshift/os/issues/604) and and our LUKS+TPM test is failing: https://github.com/openshift/os/issues/605

I suspect this may actually be an OpenSSL 3 interaction, but basically:

```
[root@cosa-devsh ~]# rpm -q tpm2-tools
tpm2-tools-5.0-6.el9.x86_64
[root@cosa-devsh ~]# tpm2_createprimary

```

This works fine on current Fedora CoreOS and RHEL8 CoreOS.  This is in qemu with swtpm.  The test framework is in https://github.com/coreos/coreos-assembler/
Comment 1 Jonathan Lebon 2021-09-20 14:49:10 UTC 
This is also affecting Fedora CoreOS rawhide too now. It's breaking any test which uses TPM2:

```
$ clevis luks bind -f -k /tmp/ignition-luks-1495034653 -d /run/ignition/dev_aliases/dev/disk/by-partlabel/varlog sss '{"pins":{"tpm2":{}},"t":1}'

```

Started happening with tpm2-tss-3.1.0-4.fc36, which was rebuilt for OpenSSL 3.0.0. So based on that and the stderr, I agree with Colin this is likely an OpenSSL-related issue.

Moving to tpm2-tss since it seems like the error actually lies in libtss2.

Wasn't sure if you preferred we cloned this to Fedora rawhide or you'd rather keep it all in this RHBZ. Can do the clone if you'd like.
Comment 2 Timothée Ravier 2021-09-21 10:21:09 UTC 
I'm raising the severity as this will prevent us from shipping RHEL 9 in RHCOS.
Comment 5 Jerry Snitselaar 2021-10-21 02:05:46 UTC 
Is this still an issue with the latest builds? With tpm2-tss-3.0.3-6.el9 and tpm2-tools-5.0-7.el9 trying tpm2_createprimary works for me in a guest running RHEL-9.0.0-20211019.d.8-x86_64-dvd1.iso.
Comment 9 RHEL Program Management 2023-02-03 07:27:45 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.

I think the answer is that it's not still a problem: https://github.com/openshift/os/issues/605#issuecomment-1421978827
