>Subject: [PATCH] Return the dbus-daemon SELinux context when asking about
> org.freedesktop.DBus
>
>Currently when asked the SELinux context of the owner of
>org.freedesktop.DBus, the dbus-daemon is returning an error.
>
>In the same situation when asked about the Unix user or the PID, the
>daemon would return its own user or pid.
>
>This patch is doing the same for the SELinux context by returning the
>daemon one.
