System V IPC

The Trusted Solaris environment supports System V IPC and provides additional interfaces for managing the CMW label, sensitivity label, and Access Control List (ACL) on System V IPC objects.

The sensitivity label of the process creating the System V IPC object is associated with each byte of data written to the object. The mandatory access policy is read-equal and write-equal. Privileged processes can access System V IPC objects at sensitivity labels other than the process sensitivity label. Chapter 11, System V Interprocess Communication describes the interfaces, security policy, and privileges for System V IPC objects.
