The snprintf() limits are complicated and slightly wrong when it does: max(0, HID_DEBUG_BUFSIZE - len - 1) The "- 1" should not be there. It means we can't use the last byte of the buffer. If we change the first snprintf() to scnprintf() then we can remove the max(). At the start of the function the strlen(buf) is going always going to be < HID_DEBUG_BUFSIZE so that is safe. If it were > HID_DEBUG_BUFSIZE then that would result in a WARN(). Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
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.
