Hi! Applied, thanks.

When testing via NFS mount LTP folder on the board, with the NFS server configured using 'anonuid' and 'anongid' options to set specific uid/gid, waitid10 fails. This is due to a uid mismatch during core dump file creation, leading to an aborted dump, resulting in the child process receiving the signal CLD_KILLED instead of CLD_DUMPED. # ./waitid10 tst_buffers.c:56: TINFO: Test is using guarded buffers tst_test.c:1732: TINFO: LTP version: 20240129 tst_test.c:1616: TINFO: Timeout per run is 0h 05m 00s waitid10.c:64: TINFO: Raising RLIMIT_CORE rlim_cur=0 -> 0 [ 296.482665] mnt_uid= 1036, curr_uid= 0 [ 296.483041] Core dump to core aborted: cannot preserve file owner waitid10.c:36: TPASS: waitid(P_ALL, 0, infop, WEXITED) passed waitid10.c:37: TPASS: infop->si_pid == pidchild (149) waitid10.c:38: TPASS: infop->si_status == SIGFPE (8) waitid10.c:39: TPASS: infop->si_signo == SIGCHLD (17) waitid10.c:42: TFAIL: infop->si_code (2) != CLD_DUMPED (3) Therefore, add .needs_tmpdir = 1 relocates the working directory to temporary directory, preventing core file creation failures due to NFS server settings.
