Subject: [PATCH AUTOSEL 4.14 23/44] can: sja1000: force the string buffer NULL-terminated
Date: Tue, 13 Aug 2019 22:18:12 -0400
Message-ID: <20190814021834.16662-23-sashal@kernel.org> (raw)
In-Reply-To: <20190814021834.16662-1-sashal@kernel.org>
From: Wang Xiayang <xywang.sjtu@sjtu.edu.cn>
[ Upstream commit cd28aa2e056cd1ea79fc5f24eed0ce868c6cab5c ]
strncpy() does not ensure NULL-termination when the input string size
equals to the destination buffer size IFNAMSIZ. The output string
'name' is passed to dev_info which relies on NULL-termination.
Use strlcpy() instead.
This issue is identified by a Coccinelle script.
