Hello,I ported ltp to Android for testing. The access02 test is failed. What is the reason? Is there any way to modify it？Thanks Here is the print information： tst_test.c:1365: TINFO: Timeout per run is 0h 05m 00s access02.c:167: TBROK: getpwnam(nobody) failed: ENOENT (2) Summary: passed 0 failed 0 broken 1 skipped 0 warnings 0

It seems that nobody exists in Android, but I will "pw=SAFE GETPWNAM ("nobody") " is modified to "pw=SAFE GETPWNAM ("root")" also reports an error.

@Bad916 FYI, this is already ported: https://android.googlesource.com/platform/external/ltp/ Although takes patches from aosp, if reasonable, generally it does not make sense to use LTP upstream for Android. It's documented on https://github.com/linux-test-project/ltp/wiki/Supported-kernel,-libc,-toolchain-versions

See also https://android.googlesource.com/platform/external/ltp/+/6dd37d0d7264a9938d531ce2f3b6c37acf6dbca1/android/skipped-tests.txt access02 is not in a skip list, thus it should work https://android.googlesource.com/platform/external/ltp/+/6dd37d0d7264a9938d531ce2f3b6c37acf6dbca1/android/tools/disabled_tests.txt LTP master even contain android specific fix: https://github.com/linux-test-project/ltp/commit/1b3e3e2755815ef3ed42e53bd7cf292b9cae69b1

@edliaw please correct me if I'm wrong.

That's correct, and the test is enabled here https://cs.android.com/android/platform/superproject/+/master:test/vts-testcase/kernel/ltp/testcase/tools/configs/stable_tests.py;l=615?q=access02 in the VTS test suite, but I will run the test tomorrow to verify just in case.

I put together a walkthrough to building and running LTP for Android here https://android.googlesource.com/platform/external/ltp/+/6dd37d0d7264a9938d531ce2f3b6c37acf6dbca1/android/ltp_android_walkthrough.md . Let me know if you find it helpful.

Edit: the test passes in my test environments. @Bad916 if you still have issues, consider filing a bug through https://issuetracker.google.com/issues?q=componentid:192639 and CC me on it. It would help if you describe how you are building LTP and what device / kernel version you are testing with.
