Subject: [PATCH v6 0/2] Adds starting the idle domain privileged
Date: Tue, 3 May 2022 07:17:29 -0400 [thread overview]
Message-ID: <20220503111731.12642-1-dpsmith@apertussolutions.com> (raw)
This series makes it so that the idle domain is started privileged under the
default policy, which the SILO policy inherits, and under the flask policy. 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 v6:
- readded the setting of is_privileged in flask_set_system_active()
- clarified comment on is_privileged in flask_set_system_active()
- added ASSERT on is_privileged and self_sid in flask_set_system_active()
- fixed err code returned on Arm for xsm_set_system_active() panic message
Changes in v5:
- dropped setting is_privileged in flask_set_system_active()
- added err code returned by xsm_set_system_active() to panic message
Changes in v4:
- reworded patch 1 commit messaged
- fixed whitespace to coding style
- fixed comment to coding style
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
