commit 204c0300c4 upstream.
Switch from strlcpy to strscpy and make sure that @count is the size of
the smaller of the source and destination buffers. This prevents
reading beyond the end of the source buffer when the source string isn't
null terminated.
Found by a modified version of syzkaller.

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.
