When we call intel_bios_is_valid_vbt(), size may not actually be the size of the VBT, but rather the size of the blob the VBT is contained in. For example, when mapping the PCI oprom, size will be the entire oprom size. We don't want to read beyond what is reported to be the VBT. So make sure we vbt->vbt_size makes sense and use that for the latter checks. v2: check for vbt_size after checking for vbt signature and give it a more meaningful error message (from Jani) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191108003602.33526-3-lucas.demarchi@intel.com
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.
