From 29fddfc7dfd6444fa61a256e9a0d0127545e1f2e Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Mon, 23 Nov 2020 10:51:24 +0100 Subject: Use libnss_files.so for tests posix/bug-ga2 and resolv/tst-leaks2 [BZ #26821] The tests posix/bug-ga2-mem and resolv/mtrace-tst-leaks2 are failing on fedora 33 as mtrace reports memory leaks. The /etc/nsswitch.conf differs between Fedora 32: hosts: files dns myhostname Fedora 33: hosts: files resolve [!UNAVAIL=return] myhostname dns Therefore /lib64/libnss_resolve.so.2 (from systemd) and the dependencies libgcc_s.so.1 and libpthread.so.0 are loaded. Usually all malloc'ed resources from getaddrinfo / gethostbyname are freed and the libraries are dlclose'd in nss/nsswitch.c:libc_freeres_fn (free_mem). Unfortunately, /lib64/libnss_resolve.so.2 is marked with DF_1_NODELETE. As this library is not unmapped, you'll see "Memory not freed". Therefore those tests are now only relying on libnss_files.so by making them test-container tests and providing the required configuration files. By moving the tests to tests-container, those are now running with "make check". Therefore the mtrace part of the tests are also moved from "make xcheck" to "make check". bug-ga2.c is now using test-driver.c in order to support WAIT_FOR_DEBUGGER environment variable. --- posix/bug-ga2.root/etc/hosts | 1 + 1 file changed, 1 insertion(+) create mode 100644 posix/bug-ga2.root/etc/hosts (limited to 'posix/bug-ga2.root/etc/hosts') diff --git a/posix/bug-ga2.root/etc/hosts b/posix/bug-ga2.root/etc/hosts new file mode 100644 index 0000000000..65151f27f5 --- /dev/null +++ b/posix/bug-ga2.root/etc/hosts @@ -0,0 +1 @@ +192.0.2.1 www.gnu.org -- cgit 1.4.1
