Date: Thu, 11 Dec 2008 16:10:08 +0100 From: Frederic Weisbecker <fweisbec@...il.com> To: Ingo Molnar <mingo@...e.hu> CC: Stephen Rothwell <sfr@...b.auug.org.au>, Linux Kernel <linux-kernel@...r.kernel.org> Subject: [PATCH 1/2] tracing/fastboot: fix len of func buffer From: Stephen Rothwell <sfr@...b.auug.org.au> Impact: fix possible stack overrun This is a port of a patch included in the mainline (KSYM_SYMBOL_LEN fixes). The current func len is not large enough to contain the max symbol len, the right size must be KSYM_SYMBOL_LEN.
