Amir Mohammad Jahangirzad 3799bec649 fs/orangefs: use snprintf() instead of sprintf() 
[ Upstream commit cdfa130465 ]

sprintf() is discouraged for use with bounded destination buffers
as it does not prevent buffer overflows when the formatted output
exceeds the destination buffer size. snprintf() is a safer
alternative as it limits the number of bytes written and ensures
NUL-termination.

Replace sprintf() with snprintf() for copying the debug string
into a temporary buffer, using ORANGEFS_MAX_DEBUG_STRING_LEN as
the maximum size to ensure safe formatting and prevent memory
corruption in edge cases.

EDIT: After this patch sat on linux-next for a few days, Dan
Carpenter saw it and suggested that I use scnprintf instead of
snprintf. I made the change and retested.

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.
