It's also causing the LTP creat07 test to fail with basically the same
bisection (I started from next/pending-fixes rather than the -rc so the
initial phases were different):
tst_test.c:1690: TINFO: LTP version: 20230929
tst_test.c:1574: TINFO: Timeout per run is 0h 01m 30s
creat07.c:37: TFAIL: creat() succeeded unexpectedly
Test timeouted, sending SIGKILL!
tst_test.c:1622: TINFO: Killed the leftover descendant processes
tst_test.c:1628: TINFO: If you are running on slow machine, try exporting LTP_TIMEOUT_MUL > 1
tst_test.c:1630: TBROK: Test killed! (timeout?)
The code in the testcase is below:
static void verify_creat(void)
{
pid_t pid;
pid = SAFE_FORK();
if (pid == 0) {
SAFE_EXECL(TEST_APP, TEST_APP, NULL);
exit(1);
}
TST_CHECKPOINT_WAIT(0);
TEST(creat(TEST_APP, O_WRONLY));
if (TST_RET != -1) {
tst_res(TFAIL, "creat() succeeded unexpectedly");
return;
}
if (TST_ERR == ETXTBSY)
tst_res(TPASS, "creat() received EXTBSY");
else
tst_res(TFAIL | TTERRNO, "creat() failed unexpectedly");
