Description Orion Poplawski 2015-09-24 15:36:06 UTC
Description of problem:

We use a cron job to reboot some machines when needed.  This is now failing with:

type=USER_AVC msg=audit(1443089508.488:3600): pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='avc:  denied  { start } for auid=n/a uid=0 gid=0 path="/usr/lib/systemd/system/reboot.target" cmdline="shutdown -r now" scontext=system_u:system_r:system_cronjob_t:s0-s0:c0.c1023 tcontext=system_u:object_r:power_unit_file_t:s0 tclass=service  exe="/usr/lib/systemd/systemd" sauid=0 hostname=? addr=? terminal=?'

Version-Release number of selected component (if applicable):
selinux-policy.noarch 3.13.1-128.13.fc22

I know I can create custom policy, but would rather not have to.

Comment 1 Wolfgang Rupprecht 2015-10-14 14:41:49 UTC
I'm seeing the same thing on all my up to date fc23 beta systems.   Reboots from daily cron using "shutdown -r +3 "update for new software"' fail in a way that cause an immediate reboot.   This causes the daily cron mail to be lost as well as any other mail (like the daily rkhunter run) that was sent in the seconds before that.  That does have security and operational implications.  All problem reports from that cron run are lost.

I'm not the OP but I can confirm that the following fixed the issue for me.  Thanks!  This was driving me crazy.
