This enables file-level integrity claims to be expressed in IPE, allowing individual files to be authorized, giving some flexibility for policy authors. Such file-level claims are important to be expressed for enforcing the integrity of packages, as well as address some of the scalability issues in a sole dm-verity based solution (# of loop back devices, etc). This solution cannot be done in userspace as the minimum threat that IPE should mitigate is an attacker downloads malicious payload with all required dependencies. These dependencies can lack the userspace check, bypassing the protection entirely. A similar attack succeeds if the userspace component is replaced with a version that does not perform the check. As a result, this can only be done in the common entry point - the kernel.
