AVC Denial "services"

[Frank Murphy]

su - root
chcon -t bin_t './system-config-services-mechanism.py'
chcon: cannot access `./system-config-services-mechanism.py': No such
file or directory



Summary:

SELinux is preventing the dbus-daemon-lau (system_dbusd_t) from executing
./system-config-services-mechanism.py.

Detailed Description:

SELinux has denied the dbus-daemon-lau from executing
./system-config-services-mechanism.py. If dbus-daemon-lau is supposed to be able
to execute ./system-config-services-mechanism.py, this could be a labeling
problem. Most confined domains are allowed to execute files labeled bin_t. So
you could change the labeling on this file to bin_t and retry the application.
If this dbus-daemon-lau is not supposed to execute
./system-config-services-mechanism.py, this could signal a intrusion attempt.

Allowing Access:

If you want to allow dbus-daemon-lau to execute
./system-config-services-mechanism.py: chcon -t bin_t
'./system-config-services-mechanism.py' If this fix works, please update the
file context on disk, with the following command: semanage fcontext -a -t bin_t
'./system-config-services-mechanism.py' Please specify the full path to the
executable, Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this selinux-policy
to make sure this becomes the default labeling.
