If /tmp is mounted nosuid and make xcheck is run, then tst-env-setuid fails UNSUPPORTED with "SGID failed: GID and EGID match" and /var/tmp/tst-sonamemove-runmod1.so.profile is created. If you then try to rerun the test with a suid mounted test-dir (the SGID binary is created in test-dir which defaults to /tmp) with something like that: make tst-env-setuid-ENV="TMPDIR=..." t=elf/tst-env-setuid test the test fails as the LD_PROFILE output file is still available from the previous run. Thus this patch removes the LD_PROFILE output file in parent before spawning the SGID binary. Even if LD_PROFILE is not supported anymore in static binaries, use a different library and thus output file for tst-env-setuid and tst-env-setuid-static in order to not interfere if both tests are run in parallel. Furthermore the checks in test_child are now more verbose. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
