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 Renaud Métrich 2022-10-17 12:42:23 UTC 
Description of problem:

When updating the microcode_ctl package, dangling symlinks remain installed in the kernel-specific /lib/firmware/<kernel> directory:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
# find /usr/lib/firmware -xtype l
/usr/lib/firmware/4.18.0-348.20.1.el8_5.x86_64/intel-ucode/06-86-04
/usr/lib/firmware/4.18.0-348.20.1.el8_5.x86_64/intel-ucode/06-86-05
/usr/lib/firmware/4.18.0-372.9.1.el8.x86_64/intel-ucode/06-86-04
/usr/lib/firmware/4.18.0-372.9.1.el8.x86_64/intel-ucode/06-86-05
/usr/lib/firmware/4.18.0-372.26.1.el8_6.x86_64/intel-ucode/06-86-04
/usr/lib/firmware/4.18.0-372.26.1.el8_6.x86_64/intel-ucode/06-86-05
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

This happens when microcodes stop being shipped, e.g. "intel-ucode/06-86-04" when updating from **microcode_ctl-4:20210608-1.el8** to latest (**microcode_ctl-4:20220207-1.20220510.1.el8_6**).

Version-Release number of selected component (if applicable):

microcode_ctl-4:20220207-1.20220510.1.el8_6 and later

How reproducible:

Always

Steps to Reproduce:
1. Install microcode_ctl-4:20210608-1.el8
2. Update to microcode_ctl-4:20220207-1.20220510.1.el8_6

or

1. Install latest microcode_ctl-4:20220207-1.20220510.1.el8_6
2. Downgrade to microcode_ctl-4:20210608-1.el8

Actual results:

Microcodes that are not shipped anymore remain dangling for all installed kernels

Expected results:

No dangling symlinks

Additional info:

The root cause is no cleaning of unshipped files in /usr/libexec/microcode_ctl/update_ucode, only cleaning of ucode_with_caveats microcodes
