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 Zdenek Pytela 2021-02-22 13:14:49 UTC 
+++ This bug was initially created as a clone of Bug #1928539 +++

Description of problem:

SELinux prevents hibernation (and therefore hybrid-sleep) on FC34 due to denying systemd-sleep access to the swap partition


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

FC34

How reproducible:

100%

Steps to Reproduce:
1. Upgrade to FC34
2. Enable hibernation by creating a swap partition and setting resume=<partition> in kernel boot params
3. Execute systemctl hibernate

Actual results:

Hibernation fails. This is a regression from FC33.

Expected results:

Hibernation succeeds.

Logs:Feb 15 08:24:08 firebert setroubleshoot[10858]: SELinux is preventing systemd-sleep from getattr access on the blk_file /dev/dm-2. For complete SELinux messages run: sealert -l 2e75eafb-e816-4902-89e7>
Feb 15 08:24:08 firebert setroubleshoot[10858]: SELinux is preventing systemd-sleep from getattr access on the blk_file /dev/dm-2.

                                                *****  Plugin catchall (100. confidence) suggests   **************************

                                                If you believe that systemd-sleep should be allowed getattr access on the dm-2 blk_file by default.
                                                Then you should report this as a bug.
                                                You can generate a local policy module to allow this access.
                                                Do
                                                allow this access for now by executing:
                                                # ausearch -c 'systemd-sleep' --raw | audit2allow -M my-systemdsleep
                                                # semodule -X 300 -i my-systemdsleep.pp



Possibly similar to #1797543

Using the workaround logged by setroubleshoot allows hibernation to succeed.
