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:
audit.log contains:
type=AVC msg=audit(1538976301.501:25547): avc:  denied  { rmdir } for  pid=5609 comm="tmpwatch" name="spool" dev="xvda1" ino=4264057 scontext=system_u:system_r:tmpreaper_t:s0-s0:c0.c1023 tcontext=system_u:object_r:mu
nin_var_lib_t:s0 tclass=dir
Cron sends emails such as:
error: failed to rmdir /var/lib/munin/cgi-tmp/munin-cgi-graph/xxx/xxx/diskstats_latency: Permission denied

Version-Release number of selected component (if applicable):
munin-2.0.40-2.el7.noarch

How reproducible:
Always

Steps to Reproduce:
1. Install munin and collect some data from localhost
2. Enable SELinux in enforcing mode
3. Wait overnight and check audit.log and cron email notifications

Actual results:
Failed to rmdir

Expected results:
Silence and tmpwatch successful

Additional info:

This is Munin cron, showing the tmpwatch it uses to clean old files. SELinux blocks the tmpwatch.

# Collect Munin data every five minutes, clean up once a day

MAILTO=root

*/5 * * * *  munin  /usr/bin/munin-cron

Fix for this should be included in bug #1164245, see attachment "Munin patch for rhel 7.5 tmpreaper policy".

This issue was not selected to be included in Red Hat Enterprise Linux 7.7 because it is seen either as low or moderate impact to a small number of use-cases. The next release will be in Maintenance Support 1 Phase, which means that qualified Critical and Important Security errata advisories (RHSAs) and Urgent Priority Bug Fix errata advisories (RHBAs) may be released as they become available.

We will now close this issue, but if you believe that it qualifies for the Maintenance Support 1 Phase, please re-open; otherwise, we recommend moving the request to Red Hat Enterprise Linux 8 if applicable.
