Some devices hang when a buffer size larger than expected is passed in the ALLOCATION LENGTH field. For REPORT SUPPORTED OPERATION CODES we currently only request a single command descriptor at a time and therefore the actual size of the command is known ahead of time. Limit the ALLOCATION LENGTH to the header size plus the command length of the opcode we are asking about.

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.
