Subject: [PATCH 0/6][next] ath6kl: wmi: Replace one-element arrays with flexible-array members
Date: Tue, 22 Feb 2022 20:38:16 -0600 [thread overview]
Message-ID: <cover.1645583264.git.gustavoars@kernel.org> (raw)
This series aims to replace one-element arrays with flexible-array
members in multiple structures in drivers/net/wireless/ath/ath6kl/wmi.h
There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().
These issues were found with the help of Coccinelle and audited and fixed,
manually.
