Date: Thu, 22 May 2014 11:48:41 -0700 From: Kees Cook <keescook@...omium.org> To: linux-kernel@...r.kernel.org Cc: "John W. Linville" <linville@...driver.com>, Fariya Fatima <fariyaf@...il.com>, linux-wireless@...r.kernel.org, netdev@...r.kernel.org Subject: [PATCH] rsi: avoid format string leak to thread name Since the rsi_create_kthread interface does not include any format string arguments, make sure that the resulting thread name can never accidentally process the name as a format string.
