From 11eb21c4659ae0bde83bcd070bc9a0f94fb3576b Mon Sep 17 00:00:00 2001 From: Patsy Franklin Date: Wed, 30 Jan 2019 18:49:27 -0500 Subject: nss: Add tst-nss-files-hosts-long test [BZ #21915] When the /etc/hosts file has a line longer than 1028 characters getent ahostsv4 and ahostsv6 will fail. This test performs a getent call on a /etc/hosts file that contains a very long line (greater than 1028) using the test-in-container framework. --- nss/tst-nss-files-hosts-long.c | 45 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 nss/tst-nss-files-hosts-long.c (limited to 'nss/tst-nss-files-hosts-long.c') diff --git a/nss/tst-nss-files-hosts-long.c b/nss/tst-nss-files-hosts-long.c new file mode 100644 index 0000000000..32f849e481 --- /dev/null +++ b/nss/tst-nss-files-hosts-long.c @@ -0,0 +1,45 @@ +/* Test getent doesn't fail with long /etc/hosts lines (Bug 21915). + Copyright (C) 2019 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public License as + published by the Free Software Foundation; either version 2.1 of the + License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
