Thorsten Blum 1ff337fc7c crypto: octeontx - Fix length check to avoid truncation in ucode_load_store 
commit 5565a72b24 upstream.

OTX_CPT_UCODE_NAME_LENGTH limits the microcode name to 64 bytes. If a
user writes a string of exactly 64 characters, the original code used
'strlen(buf) > 64' to check the length, but then strscpy() copies only
63 characters before adding a NUL terminator, silently truncating the
copied string.

Fix this off-by-one error by using 'count' directly for the length check
to ensure long names are rejected early and copied without truncation.

README 

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 reStructuredText 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.
