Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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 Robert Scheck 2019-06-21 16:28:19 UTC
Description of problem:
type=AVC msg=audit(1560791816.356:387178): avc:  denied  { signull } for  pid=22759 comm="rhsmcertd-worke" scontext=system_u:system_r:rhsmcertd_t:s0 tcontext=system_u:system_r:initrc_t:s0 tclass=process permissive=0

Version-Release number of selected component (if applicable):
selinux-policy-3.13.1-229.el7_6.12.noarch

How reproducible:
Not sure, likely an RHSM internal routine.

Actual results:
SELinux Troubleshoot mail

Expected results:
No SELinux Troubleshoot mail

Additional info:
Quite similar like bug #1379781, bug #1490961, bug #1576555, bug #1588119 or bug #1701338, but not a duplicate.

The real issue beyond is likely that the Red Hat Subscription Manager developers are having a IMHO quite bad development style by sending "random" SIGNULL signals around to figure out whether a process is running (or so) and the SELinux policy maintainers are only adding minimalistic dontaudit rules to the policy for whatever I report (rather than all simply a dontaudit for domains). Any chance to get this really addressed?
