Based on cover letter "ima: Provide more info about buffer measurement": Providing more information about buffer measurements requires modification of the existing functions ima_measure_critical_data() and process_buffer_measurement(). Unlike for file measurements, there is no integrity_iint_cache structure for storing and retrieving buffer measurements. With these changes, kernel subsystems relying on IMA to measure critical data don't have to duplicate the function to calculate the buffer digest but, instead, can get directly the one that IMA would insert, depending on the policy, in the new measurement list entry.
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 Restructured Text 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.
