If anyone has any objections, please let me know. ------------------ From: Namhyung Kim commit 66c9598bd8916c6c1319d0100ac916cac89d4b0e upstream. In the parse_events_multi_pmu_add() it passes the 'config' variable twice to parse_events_term__num() - one for config and another for loc_term. I'm not sure about the second one as it's converted to YYLTYPE variable. Asan reports it like below: In function ‘parse_events_term__num’, inlined from ‘parse_events_multi_pmu_add’ at util/parse-events.c:1602:6: util/parse-events.c:2653:64: error: array subscript ‘YYLTYPE[0]’ is partly outside array bounds of ‘char[8]’ [-Werror=array-bounds] 2653 | .err_term = loc_term ? loc_term->first_column : 0, | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~ util/parse-events.c: In function ‘parse_events_multi_pmu_add’: util/parse-events.c:1587:15: note: object ‘config’ of size 8 1587 | char *config; | ^~~~~~ cc1: all warnings being treated as errors Signed-off-by: Namhyung Kim Acked-by: Ian Rogers Cc: Adrian Hunter Cc: Ingo Molnar Cc: Jiri Olsa Cc: Kan Liang Cc: Leo Yan Cc: Peter Zijlstra Link: https://lore.kernel.org/r/20230331202949.810326-2-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo [florian: Resolve conflict in parse_events_multi_pmu_add() where term initialization is located inside the PMU scan loop in 5.10.y] Signed-off-by: Florian Fainelli Signed-off-by: Sasha Levin --- tools/perf/util/parse-events.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/perf/util/parse-events.c b/tools/perf/util/parse-events.c index c56a4d9c3be94..28a4588c18089 100644 --- a/tools/perf/util/parse-events.c +++ b/tools/perf/util/parse-events.c @@ -1593,7 +1593,7 @@ int parse_events_multi_pmu_add(struct parse_events_state *parse_state, return -1; if (parse_events_term__num(&term, PARSE_EVENTS__TERM_TYPE_USER, - config, 1, false, &config, + config, 1, false, NULL, NULL) < 0) { free(list); free(config); -- 2.53.0
