Subject: [PATCH 4.9 04/39] cfg80211: fix cfg80211_beacon_dup
Date: Mon, 26 Feb 2018 21:20:25 +0100 [thread overview]
Message-ID: <20180226201643.844709938@linuxfoundation.org> (raw)
In-Reply-To: <20180226201643.660109883@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit bee92d06157fc39d5d7836a061c7d41289a55797 upstream.
gcc-8 warns about some obviously incorrect code:
net/mac80211/cfg.c: In function 'cfg80211_beacon_dup':
net/mac80211/cfg.c:2896:3: error: 'memcpy' source argument is the same as destination [-Werror=restrict]
>From the context, I conclude that we want to copy from beacon into
new_beacon, as we do in the rest of the function.
