Device for user space to interface with MAC/veriexec.
The veriexec device features the following ioctl commands:
VERIEXEC_ACTIVE
Activate veriexec functionality
VERIEXEC_DEBUG_ON
Enable debugging mode and increment or set the debug level
VERIEXEC_DEBUG_OFF
Disable debugging mode
VERIEXEC_ENFORCE
Enforce veriexec fingerprinting (and acitvate if not already)
VERIEXEC_GETSTATE
Get current veriexec state
VERIEXEC_LOCK
Lock changes to veriexec meta-data store
VERIEXEC_LOAD
Load veriexec fingerprint if secure level is not raised (and passes the
checks for VERIEXEC_SIGNED_LOAD)
VERIEXEC_SIGNED_LOAD
Load veriexec fingerprints from loader that supports signed manifest
(and thus we can be more lenient about secure level being raised.)
Fingerprints can be loaded if the meta-data store is not locked. Also
securelevel must not have been raised or some fingerprints must have
already been loaded, otherwise it would be dangerous to allow loading.
(Note: this assumes that the fingerprints in the meta-data store at
least cover the fingerprint loader.)
