If the device supports SGLs, use these for all user requests. This format encodes the expected transfer length so it can catch short buffer errors in a user command, whether it occurred accidently or maliciously. For controllers that support SGL data mode, this is a viable mitigation to CVE-2023-6238. For controllers that don't support SGLs, log a warning in the passthrough path since not having the capability can corrupt data if the interface is not used correctly.

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.
