From 483ed8a6a00a00fbd7ef76e304ee265131207ce8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Sun, 25 Mar 2018 22:11:44 +0200 Subject: [PATCH] fuzz-unit-file: adjust check for ListenNetlink yet again The test for ListenNetlink would abort the loop if a line longer then LINE_MAX was encountered (read_line() returns -ENOBUFS in that case). Let's use the the line length limit that the unit file parses uses. https://oss-fuzz.com/v2/issue/5546208027213824/7094. --- src/fuzz/fuzz-unit-file.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/src/fuzz/fuzz-unit-file.c b/src/fuzz/fuzz-unit-file.c index 4865653f5b..a5cd9b4aa9 100644 --- a/src/fuzz/fuzz-unit-file.c +++ b/src/fuzz/fuzz-unit-file.c @@ -43,15 +43,17 @@ int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) { _cleanup_free_ char *l = NULL; const char *ll; - if (read_line(f, LINE_MAX, &l) <= 0) + if (read_line(f, LONG_LINE_MAX, &l) <= 0) break; ll = l + strspn(l, WHITESPACE); - if (startswith(ll, "ListenNetlink=")) + if (startswith(ll, "ListenNetlink=")) { /* ListenNetlink causes a false positive in msan, * let's skip this for now. */ + log_notice("Skipping test because ListenNetlink= is present"); return 0; + } } assert_se(fseek(f, offset, SEEK_SET) == 0);
