           Summary: apparmor module returns wrong error code when change_hat
                    is done against a profile with no hats
           Product: openSUSE 10.2
           Version: Beta 2
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: AppArmor
        AssignedTo: jjohansen@xxxxxxxxxx
        ReportedBy: jjohansen@xxxxxxxxxx
         QAContact: dreynolds@xxxxxxxxxx


The apparmor module returns the EPERM instead of ECHILD error code when a
change_hat call is made when confined by a profile with no hats.

The change_hat api for specifies that a change_hat done against and unconfined
application should return EPERM, while a change_hat against a confined
application with no hats returns ECHILD.  This allows an application that uses
change_hat to detect the type of failure and take an appropriate action.  In
10.2 it is not possible to detect the difference between change_hat of an
unconfined application and an application withot hats.
