[ Upstream commitbfabdd6997] Notice that *rc* can evaluate to up to 5, include/linux/netdevice.h: enum gro_result { GRO_MERGED, GRO_MERGED_FREE, GRO_HELD, GRO_NORMAL, GRO_DROP, GRO_CONSUMED, }; typedef enum gro_result gro_result_t; In case *rc* evaluates to 5, we end up having an out-of-bounds read at drivers/net/wireless/ath/wil6210/txrx.c:821: wil_dbg_txrx(wil, "Rx complete %d bytes => %s\n", len, gro_res_str[rc]); Fix this by adding element "GRO_CONSUMED" to array gro_res_str.

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.
