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 John Ferlan 2022-12-08 13:38:57 UTC 
Description of problem:

From https://bugzilla.redhat.com/show_bug.cgi?id=2103630#c15 Larry Dewey notes that the Genoa certificates were added to sev. We should backport this into sevctl for the current release. So let's include

https://github.com/virtee/sev/pull/50

after we've completed the rebase bug 2135744
Comment 1 John Ferlan 2023-02-14 21:15:09 UTC 
Given some issues building a backported patch, we'll just move this to 9.3.0 for now and have it addressed by rebase. If something changes, we can always move it back to 9.2.0.
Comment 3 Tyler Fanelli 2023-07-05 15:00:58 UTC 
@zixchen Hello. Yes, I'm planning to rebase sevctl on 9.3 within the week. This issue would be fixed with this rebase.
