Date: Mon, 27 May 2013 13:46:42 +0800 From: Chen Gang <gang.chen@...anux.com> To: "dhowells@...hat.com" <dhowells@...hat.com>, jesper.nilsson@...s.com, Richard Kuo <rkuo@...eaurora.org>, Tejun Heo <tj@...nel.org> CC: Andrew Morton <akpm@...ux-foundation.org>, David Miller <davem@...emloft.net>, "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>, Linux-Arch <linux-arch@...r.kernel.org> Subject: [PATCH] arch: frv: kernel: using vsnprintf() instead of vsprintf() Since die_if_kernel() is an extern common used function, better always check the buffer length to avoid memory overflow by a long 'str'.
