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 Lukáš Hellebrandt 2017-06-29 14:55:36 UTC
Description of problem:
When rhnsd is run as daemon (service rhnsd start), it can not send signal to rhn_check, which we need to do in bug 1409562. The AVC denial message is:

type=AVC msg=audit(1498655994.166:122): avc:  denied  { signal } for  pid=2993 comm="rhnsd" scontext=system_u:system_r:rhnsd_t:s0 tcontext=system_u:system_r:rpm_t:s0 tclass=process

Steps to Reproduce:
1. Have a Client (with setenforce 1) registered to some Satellite 5, with provisioning and packages necessary for remote command execution installed
2. Schedule a remote command with long sleep to the Client
3. Wait for rhnsd to run rhn_check
4. After the command is in picked-up state, kill rhnsd with SIGTERM
5. This should cause rhnsd to send SIGTERM to the running rhn_check
6. Mentioned AVC denial occurs, rhn_check doesn't receive the signal and rhnsd waits indefinitely for rhn_check's termination

This also happens in 7.3 with package versions in which the mentioned BZ is fixed.

Comment 2 Milos Malik 2017-06-29 16:30:22 UTC
The SELinux denial mentioned in comment#0 was caught in enforcing mode, right? Could re-run your scenario in permissive mode and collect SELinux denials? The permissive mode may reveal other SELinux denials.

# ausearch -m avc -m user_avc -m selinux_err -m user_selinux_err -i -ts today

Thank you
