Furthermore, the security policy can also be delegated to an LSM, either
a MAC system or an integrity system. For instance, the new kernel
MAY_OPENEXEC flag closes a major IMA measurement/appraisal interpreter
integrity gap by bringing the ability to check the use of scripts [1].
Other uses are expected, such as for openat2(2) [2], SGX integration
[3], bpffs [4] or IPE [5].
Confirming that this is a highly desirable feature for the proposed IPE
LSM.
