The function qat_uclo_check_image() validates the MMP and AE firmware images. If the QAT device supports firmware authentication (indicated by the handle to firmware loader), the input signed binary MMP and AE images are validated by parsing the following information: - Header length - Full size of the binary - Type of binary image (MMP or AE Firmware) Firmware binaries use RSA3K for signing and verification. The header length for the RSA3k is 0x384 bytes. All the size field values in the binary are quantified as DWORDS (1 DWORD = 4bytes). On an invalid value the function prints an error message and returns with an error code "EINVAL".

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.
