commit ab1c282c010c4f327bd7addc3c0035fd8e3c1721 upstream. Commit5304877936("NFSD: Fix strncpy() fortify warning") replaced strncpy(,, sizeof(..)) with strlcpy(,, sizeof(..) - 1), but strlcpy() already guaranteed NUL-termination of the destination buffer and subtracting one byte potentially truncated the source string. The incorrect size was then carried over in commit72f78ae00a("NFSD: move from strlcpy with unused retval to strscpy") when switching from strlcpy() to strscpy(). Fix this off-by-one error by using the full size of the destination buffer again.

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.
