From 8001530d5af707eb9a158839c8f651eb6c1cb3c2 Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Thu, 11 Dec 2008 16:10:08 +0100 Subject: [PATCH] tracing/fastboot: fix len of func buffer 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.
