Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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:
possible policy change is questionable because the dir in /tmp should not have this context. actually it is backup made by root user which preserves original context.
it prevents tmpwatch from working correctly

grep tmpwatch /var/log/audit/audit.log | audit2allow
#============= tmpreaper_t ==============
allow tmpreaper_t etc_t:dir setattr;
allow tmpreaper_t root_t:dir setattr;
SELinux is preventing /usr/sbin/tmpwatch from 'setattr' accesses on the directory .
***** Plugin catchall (100. confidence) suggests **************************
If you believe that tmpwatch should be allowed setattr access on the directory 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:
# grep tmpwatch /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Yes, this is questionable but you won't be able to fix labeling in /tmp which is correct. We probably should have a similar policy for tmpreaper_t as we have for systemd_tmpfiles_t.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
