X Window Server Clearance and Minimum Label

These routines set the session high clearance and the session low minimum label for the X Window Server. Refer to the XTSOLsetSessionHI(3) and XTSOLsetSessionLO(3) man pages.

• The session high clearance is set from the workstation owner's clearance at login, and must be dominated by the owner's clearance and the upper bound of the machine monitor's label range. Once changed, connection requests from clients running at a sensitivity label higher than the window server clearance are rejected unless they have privilege.

• The session low minimum label is set from the workstation owner's minimum label at login and must be greater than the user's administratively set minimum label and the lower bound of the machine monitor's label range. Once changed, connection requests from clients running at a sensitivity label lower than the window server sensitivity label are rejected unless they have privilege.

These interfaces are reserved for the Window Manager.
