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:

https://fedoraproject.org/wiki/Changes/SELinux_Parallel_Autorelabel

 Summary

After a system's SELinux mode is switched from disabled to enabled, or after an administrator runs fixfiles onboot, SELinux autorelabel will be run in parallel by default. 

Detailed Description

SELinux tools restorecon and fixfiles recently gained the ability to relabel files in parallel using the -T nthreads option. This option is currently not used in the automatic relabel after reboot. When users want/need the parallel relabeling they have to specify the option explicitly (e.g. fixfiles -T 0 onboot). With this change -T 0 (0 == use all available CPU cores) will be the default for fixfiles onboot and users will have to use fixfiles -T 1 onboot to force it to use only one thread.

The rationale is that when autorelabel runs, there are no other resource-intensive processes running on the system, so it's fine (and actually better) to use all available parallelism to speed up the task and get to a fully booted system faster.
