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.c | 13 +++++++------ 1 file changed, 7 insertions(+), 6 deletions(-) (limited to 'posix/bug-ga2.c') diff --git a/posix/bug-ga2.c b/posix/bug-ga2.c index 5ea759b..712e40d 100644 --- a/posix/bug-ga2.c +++ b/posix/bug-ga2.c @@ -3,9 +3,10 @@ #include #include #include +#include -int -main (void) +static int +do_test (void) { struct addrinfo hints, *res; int i, ret; @@ -20,11 +21,11 @@ main (void) ret = getaddrinfo ("www.gnu.org", "http", &hints, &res); if (ret) - { - printf ("%s\n", gai_strerror (ret)); - return 1; - } + FAIL_EXIT1 ("%s\n", gai_strerror (ret)); + freeaddrinfo (res); } return 0; } + +#include -- cgit v1.1
