The memcpy() in ath_key_config() was attempting to write across neighboring struct members in struct ath_keyval. Introduce a wrapping struct_group, kv_values, to be the addressable target of the memcpy without overflowing an individual member. Silences the false positive run-time warning: memcpy: detected field-spanning write (size 32) of single field "hk.kv_val" at drivers/net/wireless/ath/key.c:506 (size 16) Link: https://bbs.archlinux.org/viewtopic.php?id=282254 Cc: Kalle Valo <kvalo@kernel.org> Cc: "David S.

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.
