From 5651285934ade033c0662afbbee940855f6bd2fb Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Sat, 26 Dec 2015 12:43:28 +0100 Subject: shared: fix handling of suffix "." in dns_name_compare_func() All our other domain name handling functions make no destinction between domain names that end in a dot plus a NUL, or those just ending in a NUL. Make sure dns_name_compare_func() and dns_label_unescape_suffix() do the same. --- src/test/test-dns-domain.c | 18 ++++++++++++++++-- 1 file changed, 16 insertions(+), 2 deletions(-) (limited to 'src/test') diff --git a/src/test/test-dns-domain.c b/src/test/test-dns-domain.c index 78c5631ff1..1b0cb153f7 100644 --- a/src/test/test-dns-domain.c +++ b/src/test/test-dns-domain.c @@ -140,9 +140,9 @@ static void test_dns_label_unescape_suffix(void) { test_dns_label_unescape_suffix_one("hallo\\", "hallo", "hallo", 20, -EINVAL, -EINVAL); test_dns_label_unescape_suffix_one("hallo\\032 ", "hallo ", "", 20, 7, 0); test_dns_label_unescape_suffix_one(".", "", "", 20, 0, 0); - test_dns_label_unescape_suffix_one("..", "", "", 20, 0, 0); + test_dns_label_unescape_suffix_one("..", "", "", 20, 0, -EINVAL); test_dns_label_unescape_suffix_one(".foobar", "foobar", "", 20, 6, -EINVAL); - test_dns_label_unescape_suffix_one("foobar.", "", "foobar", 20, 0, 6); + test_dns_label_unescape_suffix_one("foobar.", "foobar", "", 20, 6, 0); test_dns_label_unescape_suffix_one("foo\\\\bar", "foo\\bar", "", 20, 7, 0); test_dns_label_unescape_suffix_one("foo.bar", "bar", "foo", 20, 3, 3); test_dns_label_unescape_suffix_one("foo..bar", "bar", "", 20, 3, -EINVAL); @@ -546,6 +546,19 @@ static void test_dns_name_equal_skip(void) { test_dns_name_equal_skip_one("", 2, "foo", 0); } +static void test_dns_name_compare_func(void) { + assert_se(dns_name_compare_func("", "") == 0); + assert_se(dns_name_compare_func("", ".") == 0); + assert_se(dns_name_compare_func(".", "") == 0); + assert_se(dns_name_compare_func("foo", "foo.") == 0); + assert_se(dns_name_compare_func("foo.", "foo") == 0); + assert_se(dns_name_compare_func("foo", "foo") == 0); + assert_se(dns_name_compare_func("foo.", "foo.") == 0); + assert_se(dns_name_compare_func("heise.de", "HEISE.DE.") == 0); + + assert_se(dns_name_compare_func("de.", "heise.de") != 0); +} + int main(int argc, char *argv[]) { test_dns_label_unescape(); @@ -569,6 +582,7 @@ int main(int argc, char *argv[]) { test_dns_name_suffix(); test_dns_name_count_labels(); test_dns_name_equal_skip(); + test_dns_name_compare_func(); return 0; } -- cgit v1.2.3-54-g00ecf
