Thorsten Blum 8c5b120059 NFSD: Fix destination buffer size in nfsd4_ssc_setup_dul() 
commit ab1c282c01 upstream.

Commit 5304877936 ("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 commit 72f78ae00a ("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.
