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 Milos Malik 2015-11-06 10:52:13 UTC 
Description of problem:
# sesearch -s virt_qemu_ga_t -t var_run_t -T
Found 2 semantic te rules:
   type_transition virt_qemu_ga_t var_run_t : file virt_qemu_ga_var_run_t; 
   type_transition virt_qemu_ga_t var_run_t : dir virt_qemu_ga_var_run_t; 
#

The qga.state file gets a correct label during its creation, but ...

# matchpathcon /var/run/qga.state 
/var/run/qga.state	system_u:object_r:var_run_t:s0
#

Steps to Reproduce:
# service qemu-ga start
Starting qemu-ga:                                          [  OK  ]
# service qemu-ga status
qemu-ga (pid  5686) is running...
# service qemu-ga stop
Stopping qemu-ga:                                          [  OK  ]
# service qemu-ga status
qemu-ga is stopped
# ls -Z /var/run/qga.state 
-rw-------. root root unconfined_u:object_r:virt_qemu_ga_var_run_t:s0 /var/run/qga.state
# restorecon -v /var/run/qga.state 
restorecon reset /var/run/qga.state context unconfined_u:object_r:virt_qemu_ga_var_run_t:s0->unconfined_u:object_r:var_run_t:s0
# service qemu-ga start
Starting qemu-ga:                                          [  OK  ]
# service qemu-ga status
qemu-ga dead but subsys locked
