[ Upstream commit 3e1c6846b9e108740ef8a37be80314053f5dd52a ] The value adapter->rss_conf is stored in DMA memory, and it is assigned to rssConf, so rssConf->indTableSize can be modified at anytime by malicious hardware. Because rssConf->indTableSize is assigned to n, buffer overflow may occur when the code "rssConf->indTable[n]" is executed. To fix this possible bug, n is checked after being used.

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.
