From 920e9402a4d6101bbbed2ef7584d85a3c3de0eaa Mon Sep 17 00:00:00 2001 From: Joshua Rogers Date: Fri, 2 Apr 2021 22:23:11 +0000 Subject: Add support for standalone leak-sanitizer, introducting the environment variable AFL_USE_LSAN. AFL_USE_LSAN introduces the macro __AFL_CHECK_LEAK() which will check for a memory leak when the macro is run. This is especially helpful when using __AFL_LOOP(). If __AFL_LEAK_CHECK() is not used when AFL_USE_LSAN=1 is set, the leak checker will run when the program exits. --- src/afl-showmap.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/afl-showmap.c') diff --git a/src/afl-showmap.c b/src/afl-showmap.c index 7bf5a9c7..bf076683 100644 --- a/src/afl-showmap.c +++ b/src/afl-showmap.c @@ -570,6 +570,10 @@ static void set_up_environment(afl_forkserver_t *fsrv) { "handle_sigfpe=0:" "handle_sigill=0", 0); + setenv("LSAN_OPTIONS", + "exitcode=" STRINGIFY(LSAN_ERROR) ":" + "fast_unwind_on_malloc=0", + 0); setenv("UBSAN_OPTIONS", "halt_on_error=1:" -- cgit 1.4.1
