From 5660ce34241ab204bf78fbcaa5e09318c2748d37 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 9 Dec 2009 20:26:18 +0100 Subject: [PATCH] perf tools: Correct size given to memset Memset should be given the size of the structure, not the size of the pointer. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ type T; T *x; expression E; @@ memset(x, E, sizeof( + * x)) // Signed-off-by: Julia Lawall Cc: Peter Zijlstra Cc: Paul Mackerras LKML-Reference: Signed-off-by: Ingo Molnar --- tools/perf/util/probe-event.c | 2 +- tools/perf/util/trace-event-parse.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/tools/perf/util/probe-event.c b/tools/perf/util/probe-event.c index 9480d9941cc0..d14a4585bcaf 100644 --- a/tools/perf/util/probe-event.c +++ b/tools/perf/util/probe-event.c @@ -376,7 +376,7 @@ static void clear_probe_point(struct probe_point *pp) free(pp->args); for (i = 0; i < pp->found; i++) free(pp->probes[i]); - memset(pp, 0, sizeof(pp)); + memset(pp, 0, sizeof(*pp)); } /* Show an event */ diff --git a/tools/perf/util/trace-event-parse.c b/tools/perf/util/trace-event-parse.c index 6ffe9d63d85d..c5c32be040bf 100644 --- a/tools/perf/util/trace-event-parse.c +++ b/tools/perf/util/trace-event-parse.c @@ -1477,7 +1477,7 @@ process_fields(struct event *event, struct print_flag_sym **list, char **tok) goto out_free; field = malloc_or_die(sizeof(*field)); - memset(field, 0, sizeof(field)); + memset(field, 0, sizeof(*field)); value = arg_eval(arg); field->value = strdup(value); -- 2.20.1
