Requiring Security Labels for IPC Objects

The MLIPCOBJ option specifies whether security labels are required for UNIX IPC objects, such as semaphores, in an MLS system. This option should be set if you want to use MAC protection and security labels for UNIX IPC objects.

Important! Before activating this option, let the system run with MLS active, so that the system is able to label IPC objects as they are created, without failing the access requests.
