Description Jan Hutař 2013-09-28 04:37:54 EDT
Description of problem:
When rhn_check initiates reboot, shutdown.pid file is created with incorrect SELinux context

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

How reproducible:

Steps to Reproduce:
1. Use Satellite to initiate remote reboot on the system
2. # rhn_check
3. # ls -alZ /var/run/shutdown.pid
-rw-r--r--. root root unconfined_u:object_r:rpm_var_run_t:s0 /var/run/shutdown.pid
4. # ps axZ | grep shutdown
unconfined_u:system_r:rpm_t:s0-s0:c0.c1023 29597 pts/0 S   0:00 /sbin/shutdown -r +3
unconfined_u:system_r:rpm_t:s0-s0:c0.c1023 29598 pts/0 Z   0:00 [shutdown] <defunct>
5. # shutdown -c
shutdown: Shutdown is not running

Actual results:
You can not stop shutdown initiated by Satellite/rhn_check with `shutdown -c`.

Workaround is easy though: `killall shutdown`.

Expected results:
You should be able to stop shutdown initiated by Satellite/rhn_check with `shutdown -c`.

Additional info:
IMO not a 560 blocker. Maybe this is shutdown or SELinux policy issue?
Comment 1 Jan Hutař 2013-09-28 04:48:56 EDT
This does not happen on RHEL5.

Comment 3 Milan Zázrivec 2013-10-01 09:25:32 EDT
Is this a regression from RHEL-6.3?
Comment 4 Jan Hutař 2013-10-04 06:48:28 EDT
No, using RHEL-6.3 I see the same:


# ls -alZ /var/run/shutdown.pid
-rw-r--r--. root root unconfined_u:object_r:rpm_var_run_t:s0 /var/run/shutdown.pid
# ps axZ | grep shutdown
unconfined_u:system_r:rpm_t:s0-s0:c0.c1023 14032 pts/0 S   0:00 /sbin/shutdown -r +3
unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 14036 pts/0 S+   0:00 grep shutdown
# shutdown -c
shutdown: Cannot find pid of running shutdown
Comment 5 Milan Zázrivec 2013-10-04 09:48:42 EDT
All right, I'm postponing this to RHEL-6.6
Comment 7 Matej Kollar 2015-03-04 06:14:03 EST
This would be better handled as selinux-policy.
Comment 11 Miroslav Grepl 2015-04-01 04:42:21 EDT
could you re-test it with 

$cat mypol.te
policy_module(mypol, 1.0)
 type rpm_t;

Comment 12 Milos Malik 2015-04-01 09:53:01 EDT
I'm not familiar with Satellite, but Jan can test it, right?

    Allow rhn_check running as rpm to domtrans to shutdown domain
