Description Milos Malik 2015-11-06 05:52:13 EST
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

Version-Release number of selected component (if applicable):

How reproducible:

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

Actual results:

Expected results:
 * no SELinux denials
Comment 1 Miroslav Grepl 2015-11-09 09:49:52 EST
We need to add a default labeling.
