The IMA measurement/appraisal policy, which is described in Documentation/ABI/testing/ima_policy, can be based on a number of criteria. One of these criteria are LSM subj/obj labels. The IMA measurement/appraisal policy should be loaded as early as possible, but only after the LSM policy has been loaded.
