From 594087a04eea544356f9c52e83c1a9bc380ce80f Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Fri, 12 Mar 2010 18:22:17 -0500 Subject: perf probe: Fix probe_point buffer overrun Fix probe_point array-size overrun problem. In some cases (e.g. inline function), one user-specified probe-point can be translated to many probe address, and it overruns pre-defined array-size. This also removes redundant MAX_PROBES macro definition.

Eventually we should remove the MAX_PROBES limit, but that is a larger patch not eligible to perf/urgent treatment. ] Signed-off-by: Ingo Molnar --- tools/perf/builtin-probe.c | 1 - 1 file changed, 1 deletion(-) (limited to 'tools/perf/builtin-probe.c') diff --git a/tools/perf/builtin-probe.c b/tools/perf/builtin-probe.c index c30a33592340..152d6c9b1fa4 100644 --- a/tools/perf/builtin-probe.c +++ b/tools/perf/builtin-probe.c @@ -47,7 +47,6 @@ #include "util/probe-event.h" #define MAX_PATH_LEN 256 -#define MAX_PROBES 128 /* Session management structure */ static struct { -- cgit v1.2.1
