AppArmor: functions for domain transitions
AppArmor routines for controling domain transitions, which can occur at exec or through self directed change_profile/change_hat calls. Unconfined tasks are checked at exec against the profiles in the confining profile namespace to determine if a profile should be attached to the task. Confined tasks execs are controlled by the profile which provides rules determining which execs are allowed and if so which profiles should be transitioned to. Self directed domain transitions allow a task to request transition to a given profile. If the transition is allowed then the profile will be applied, either immeditately or at exec time depending on the request. Immeditate self directed transitions have several security limitations but have uses in setting up stub transition profiles and other limited cases.
