Subject: [PATCH AUTOSEL 4.14 032/103] rtl8187: Fix warning generated when strncpy() destination length matches the sixe argument
Date: Fri, 8 Nov 2019 06:41:57 -0500 [thread overview]
Message-ID: <20191108114310.14363-32-sashal@kernel.org> (raw)
In-Reply-To: <20191108114310.14363-1-sashal@kernel.org>
From: Larry Finger <Larry.Finger@lwfinger.net>
[ Upstream commit 199ba9faca909e77ac533449ecd1248123ce89e7 ]
In gcc8, when the 3rd argument (size) of a call to strncpy() matches the
length of the first argument, the compiler warns of the possibility of an
unterminated string. Using strlcpy() forces a null at the end.
