Enable IPE policy authors to indicate trust for a singular fsverity file, identified by the digest information, through "fsverity_digest" and all files using valid fsverity builtin signatures via "fsverity_signature". 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
