1702724 – tuned doesn't react to SIGHUP when wrong profile has been selected

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.

Fixed In Version:	tuned-2.11.0-9.el7
Doc Type:	Bug Fix
Doc Text:	.`tuned` no longer hangs on SIGHUP when a non-existent profile is selected When the `tuned` service receives the SIGHUP signal, it attempts to reload the profile. Prior to this update, `tuned` was unable to correctly handle situations when: * The `tuned` profile was set to a non-existent profile, or * The automatic profile selection mode was active and the recommended profile was non-existent. As a consequence, the `tuned` service became unresponsive and had to be restarted. This bug has been fixed, and the `tuned` service no longer hangs in the described scenarios. Note that the `tuned` behavior has changed with this update. Previously, when the user executed the `tuned-adm off` command and restarted the `tuned` service, `tuned` tried to load the recommended profile. Now, `tuned` loads no profile even if the recommended profile exists.
