Date: Tue, 20 Dec 2011 17:18:03 -0200 From: Arnaldo Carvalho de Melo <acme@...radead.org> To: Ingo Molnar <mingo@...e.hu> Cc: linux-kernel@...r.kernel.org, Robert Richter <robert.richter@....com>, Arnaldo Carvalho de Melo <acme@...hat.com> Subject: [PATCH 02/10] perf evsel: Fix uninitialized memory access to struct perf_sample From: Robert Richter <robert.richter@....com> 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.
