1. did XSM hooks are placed in the source code of xen manually?

As we all know, the hooks are used to insert authorization checks on the security-critical operation, now my question is,

2. how to identify security-critical operation?

security-critical operations are inter-VM communication and cooperation implementing on top of shared virtual resources,

3. does the XSM hooks cover all the operations completely?

thanks.
