[ Upstream commit 7a7b7f575a25aa68ee934ee8107294487efcb3fe ]
strnlen() may return 0 (e.g. for "\0\n" string), it's better to
check the result of strnlen() before using 'len - 1' expression
for the 'buf' array index.
Detected using the static analysis tool - Svace.

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.
