[ Upstream commit156e0b1a81] The dev_info.name[] array has space for RIO_MAX_DEVNAME_SZ + 1 characters. But the problem here is that we don't ensure that the user put a NUL terminator on the end of the string. It could lead to an out of bounds read.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
