Update. 2004-02-23 Jakub Jelinek <jakub@redhat.com> * sysdeps/posix/getaddrinfo.c (gaih_inet): If _res has not been inited yet, try to init it before saving old _res.options. * posix/Makefile (xtests): Add bug-ga2. (generated): Add bug-ga2.mtrace and bug-ga2-mem. (xtests): Depend on bug-ga2-mem. ($(objpfx)bug-ga2-mem, bug-ga2-ENV): New. * posix/bug-ga2.c: New test.

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.
