It then introduces a new one-way XSM hook, xsm_transition_running, that is hooked by an XSM policy to transition the idle domain to its running privilege level. Changes in v3: - renamed *_transition_running() to *_set_system_active() - changed the XSM hook set_system_active() from void to int return - added ASSERT check for the expected privilege level each XSM policy expected - replaced a check against is_privileged in each arch with checking the return value from the call to xsm_set_system_active() Changes in v2: - renamed flask_domain_runtime_security() to flask_transition_running() - added the missed assignment of self_sid Daniel P.
