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 of problem:
fwupd package presence on any RHEL8 UEFI systems.
fwupd package is not mandatory for any UEFI setup but due to shim-x64 dependency on dbxtool it cannot be removed.
Version-Release number of selected component (if applicable):
shim-x64-15.6-1.el8.x86_64
How reproducible:
[root@fastvm-rhel-8-6-uefi-166 ~]# dnf deplist shim-x64-15.6-1.el8.x86_64
package: shim-x64-15.6-1.el8.x86_64
dependency: dbxtool >= 0.6-3
provider: dbxtool-8-5.el8_3.2.x86_64
provider: fwupd-1.7.4-2.el8.x86_64
dependency: efi-filesystem
provider: efi-filesystem-3-3.el8.noarch
dependency: mokutil >= 1:0.3.0-1
provider: mokutil-1:0.3.0-11.el8_6.1.x86_64
[root@fastvm-rhel-8-6-uefi-166 ~]# dnf remove fwupd
Updating Subscription Management repositories.

Removing:
fwupd x86_64 1.7.4-2.el8 @anaconda 8.2 M
Removing dependent packages:
shim-x64 x86_64 15.5-2.el8 @anaconda 3.6 M
...
Actual results:
shim-x64 is dependent on fwupd [dbxtool]
Expected results:
shim-x64 is not dependent on fwupd [dbxtool]
Additional info:
Since the hypervisor solution is managing the virtual hardware for the instances on Public Cloud Azure, the fwupd package is not needed there.
The other concern is that fwupd service is writing errors/warnings "... failed to ...." in the log file during and after the sosreport is collected. Any kind of errors related to important topics like Firmware can be interpreted wrong.
fwupd is used for the security-critical purpose of updating dbx in addition to firmware updates in general. dbxtool is deprecated, so using that instead defeats the purpose of maintaining strong platform security.
