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.

                 tcontext=unconfined_u:object_r:devlog_t:s0 tclass=sock_file

Version-Release number of selected component (if applicable):
selinux-policy-3.7.19-147.el6

How reproducible:
100%

Steps to Reproduce:
1. useradd -Z guest_u testuser
2. passwd testuser
3. ssh-copy-id testuser@localhost
  
Actual results:
Permission denied (ssh-copy-id)/No error msg with ssh. AVC in description.

Expected results:
No denial.

Additional info:
I think something may be missing from the log?

Just try to switch to permissive mode for all AVC msgs. We don't allow guest_t to send log messages.

I think it is the only one, though I can recheck

Fixed in selinux-policy-3.7.19-149.el6
