Simon Horman 89704e7aaa net: mvpp2: Increase size of queue_name buffer
[ Upstream commit 91d516d4de48532d967a77967834e00c8c53dfe6 ]

Increase size of queue_name buffer from 30 to 31 to accommodate
the largest string written to it. This avoids truncation in
the possibly unlikely case where the string is name is the
maximum size.

Flagged by gcc-14:

  .../mvpp2_main.c: In function 'mvpp2_probe':
  .../mvpp2_main.c:7636:32: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=]
   7636 |                  "stats-wq-%s%s", netdev_name(priv->port_list[0]->dev),
        |                                ^
  .../mvpp2_main.c:7635:9: note: 'snprintf' output between 10 and 31 bytes into a destination of size 30
   7635 |         snprintf(priv->queue_name, sizeof(priv->queue_name),
        |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   7636 |                  "stats-wq-%s%s", netdev_name(priv->port_list[0]->dev),
        |                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   7637 |                  priv->port_count > 1 ? "+" : "");
        |                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Introduced by commit 118d6298f6 ("net: mvpp2: add ethtool GOP statistics").
I am not flagging this as a bug as I am not aware that it is one.

Compile tested only.

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 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.
