Still issues with SElinux, NetworkManager, and ACPI suspend

[Matthew Saltzman]

Recent versions of NetworkManager use dbus signals to control actions 
related to suspend/resume (among others).

In enforcing mode, using selinux-policy-targeted-1.27.1-2.7.

The suspend script runs without error when executed from the command line, 
but produces these errors when invoked by pressing the suspend key.

On suspend, /var/log/debug reports:

     Oct 22 12:59:14 vincent52 dbus: Can't send to audit system: USER_AVC
     pid=2180 uid=81 loginuid=-1 message=avc:  denied  { send_msg } for
     msgtype=method_call interface=org.freedesktop.NetworkManager
     member=sleep dest=org.freedesktop.NetworkManager spid=31524 tpid=2239
     scontext=system_u:system_r:apmd_t
     tcontext=system_u:system_r:NetworkManager_t tclass=dbus

On resume, /var/log/debug reports:

     Oct 22 12:59:39 vincent52 dbus: Can't send to audit system: USER_AVC
     pid=2180 uid=81 loginuid=-1 message=avc:  denied  { send_msg } for
     msgtype=method_call interface=org.freedesktop.NetworkManager
     member=wake dest=org.freedesktop.NetworkManager spid=31542 tpid=2239
     scontext=system_u:system_r:apmd_t
     tcontext=system_u:system_r:NetworkManager_t tclass=dbus

No messages appear in /var/log/audit/audit.log.

The relevant section of the suspend script is:

     /usr/bin/dbus-send --system --dest=org.freedesktop.NetworkManager \
     --type=method_call /org/freedesktop/NetworkManager \
     org.freedesktop.NetworkManager.sleep

     sync
     echo -n "mem" > /sys/power/state

     /usr/bin/dbus-send --system --dest=org.freedesktop.NetworkManager \
     --type=method_call /org/freedesktop/NetworkManager \
     org.freedesktop.NetworkManager.wake

Thanks.
