From: Yunfeng Ye <yeyunfeng@huawei.com> [ Upstream commit 1785fbb73896dbd9d27a406f0d73047df42db710 ] There are memory leaks and file descriptor resource leaks in process_mapfile() and main(). Fix this by adding free(), fclose() and free_arch_std_events() on the error paths. Fixes: 80eeb67fe577 ("perf jevents: Program to convert JSON file") Fixes: 3f056b66647b ("perf jevents: Make build fail on JSON parse error") Fixes: e9d32c1bf0cd ("perf vendor events: Add support for arch standard events") Signed-off-by: Yunfeng Ye <yeyunfeng@huawei.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Feilong Lin <linfeilong@huawei.com> Cc: Hu Shiyuan <hushiyuan@huawei.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: John Garry <john.garry@huawei.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Luke Mujica <lukemujica@google.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Zenghui Yu <yuzenghui@huawei.com> Link: http://lore.kernel.org/lkml/d7907042-ec9c-2bef-25b4-810e14602f89@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org> Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> --- tools/perf/pmu-events/jevents.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) diff --git a/tools/perf/pmu-events/jevents.c b/tools/perf/pmu-events/jevents.c index 6cd9623..38b5888 100644 --- a/tools/perf/pmu-events/jevents.c +++ b/tools/perf/pmu-events/jevents.c @@ -754,6 +754,7 @@ static int process_mapfile(FILE *outfp, char *fpath) char *line, *p; int line_num; char *tblname; + int ret = 0; pr_info("%s: Processing mapfile %s\n", prog, fpath); @@ -765,6 +766,7 @@ static int process_mapfile(FILE *outfp, char *fpath) if (!mapfp) { pr_info("%s: Error %s opening %s\n", prog, strerror(errno), fpath); + free(line); return -1; } @@ -791,7 +793,8 @@ static int process_mapfile(FILE *outfp, char *fpath) /* TODO Deal with lines longer than 16K */ pr_info("%s: Mapfile %s: line %d too long, aborting\n", prog, fpath, line_num); - return -1; + ret = -1; + goto out; } line[strlen(line)-1] = '\0'; @@ -821,7 +824,9 @@ static int process_mapfile(FILE *outfp, char *fpath) out: print_mapping_table_suffix(outfp); - return 0; + fclose(mapfp); + free(line); + return ret; } /* @@ -1118,6 +1123,7 @@ int main(int argc, char *argv[]) goto empty_map; } else if (rc < 0) { /* Make build fail */ + fclose(eventsfp); free_arch_std_events(); return 1; } else if (rc) { @@ -1130,6 +1136,7 @@ int main(int argc, char *argv[]) goto empty_map; } else if (rc < 0) { /* Make build fail */ + fclose(eventsfp); free_arch_std_events(); return 1; } else if (rc) { @@ -1147,6 +1154,8 @@ int main(int argc, char *argv[]) if (process_mapfile(eventsfp, mapfile)) { pr_info("%s: Error processing mapfile %s\n", prog, mapfile); /* Make build fail */ + fclose(eventsfp); + free_arch_std_events(); return 1; } -- 1.8.3
