Message-ID: <1323966762-8574-2-git-send-email-robert.richter@amd.com> Date: Thu, 15 Dec 2011 17:32:39 +0100 From: Robert Richter <robert.richter@....com> To: Arnaldo Carvalho de Melo <acme@...hat.com> CC: Ingo Molnar <mingo@...e.hu>, LKML <linux-kernel@...r.kernel.org>, Robert Richter <robert.richter@....com> Subject: [PATCH 1/4] perf tools: Fix uninitialized memory access to struct perf_sample Memory in struct perf_sample is not fully initialized during parsing. Depending on sampling data some parts may left unchanged. Zero out struct perf_sample first to avoid access to uninitialized memory.
