Subject: [LTP] [PATCH v3] waitid10: Add .needs_tmpdir=1 to run test in temporary directory
Date: Mon, 8 Apr 2024 15:18:48 +0800 [thread overview]
Message-ID: <20240408071848.80862-1-minachou@andestech.com> (raw)
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.
