Also this and a few other operations do not need arg to be passed as last argument. Basically all the GET operations that return the value directly in the return value does not need arg to be passed. > - } > - if ((status = semctl(semid, 0, GETNCNT, arg)) == -1) { > - tst_resm(TFAIL, "semctl(GETNCNT) failed errno = %d", errno); > + if ((status = semctl(semid, 0, GETNCNT, arg)) == -1) > + tst_res(TFAIL, "semctl(GETNCNT) failed errno = %d", errno); > > - } > - if (status != 0) { > - tst_resm(TFAIL, "error: unexpected semncnt %d", status); > + if (status != 0) > + tst_res(TFAIL, "error: unexpected semncnt %d", status); > > - } > - if ((status = semctl(semid, 0, GETZCNT, arg)) == -1) { > - tst_resm(TFAIL, "semctl(GETZCNT) failed errno = %d", errno); > - > - } > - if (status != 0) { > - tst_resm(TFAIL, "error: unexpected semzcnt %d", status); > - > - } > + if ((status = semctl(semid, 0, GETZCNT, arg)) == -1) > + tst_res(TFAIL, "semctl(GETZCNT) failed errno = %d", errno); > > - tst_resm(TPASS, "semctl07 ran successfully!"); > + if (status != 0) > + tst_res(TFAIL, "error: unexpected semzcnt %d", status); > > - cleanup(); > - tst_exit(); > + tst_res(TPASS, "semctl07 ran successfully!"); This part is broken. We do issue the TPASS here even if one of the above statement issued TFAIL. So we either change the code to produce TPASS/TFAIL pair on each check e.g. if (status != arg.val) { tst_res(TFAIL, "semctl(GETVAL) returned %d expected %d", arg.val, status); } else { tst_res(TPASS, "semctl(GETVAL) returned %d", arg.val); } Or we have to maintain flag that is set to non-zero on any failure and then we can, at the end of the test do: if (!flag) tst_res(TPASS, "everything is fine"); > } > > -void setup(void) > +static void setup(void) > { > - tst_sig(NOFORK, DEF_HANDLER, cleanup); > - > - TEST_PAUSE; > - > - tst_tmpdir(); > - > - /* get an IPC resource key */ > - key = getipckey(); > + key_t key = GETIPCKEY(); > nsems = 1; > > - if ((semid = semget(key, nsems, SEM_RA | IPC_CREAT)) == -1) { > - tst_brkm(TFAIL, NULL, "semget() failed errno = %d", errno); > - } > + semid = SAFE_SEMGET(key, nsems, SEM_RA | IPC_CREAT); > } > > -void cleanup(void) > +static void cleanup(void) > { > - rm_sema(semid); > - tst_rmdir(); > + if (semid != -1) > + SAFE_SEMCTL(semid, 0, IPC_RMID); > } > + > +static struct tst_test test = { > + .setup = setup, > + .cleanup = cleanup, > + .needs_root = 1, > + .test_all = verify_semctl, > +}; > -- > 1.8.3.1 > > > > > -- > Mailing list info: https://lists.linux.it/listinfo/ltp
