[ Upstream commit cdfa1304657d6f23be8fd2bb0516380a3c89034e ] 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.
