On my machine, TEST8 & TEST9 are failing as the expeted error is not equal to the actual error. After analysis, I found that the TEST8 & TEST9 are trying to set CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID respectively. But from the man pages, it says that "According to POSIX.1-2001, the CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID clocks should be settable using clock_settime(). How-ever, the clocks currently are not settable". Also, in the below code snippet of ltp/testcases/kernel/timers/clock_settime/clock_settime03.c the if statement looks nothing for my kernel-2.6.32. So, the value of testcases[7] and testcases[8] will get assigned to EFAULT but actually both of them should get set to EINVAL as the support is not available on kernel-2.6.32. ----------- /* PROCESS_CPUTIME_ID & THREAD_CPUTIME_ID are not supported on * kernel versions lower than 2.6.12 and changed back in 2.6.38 */ if ((tst_kvercmp(2, 6, 12)) < 0 || (tst_kvercmp(2, 6, 38)) >= 0) { testcases[7] = EINVAL; testcases[8] = EINVAL; } else { testcases[7] = EFAULT; testcases[8] = EFAULT; } ------------ I would like to know from which version onwards the CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID clocks can be set using clock_settime() so that I can generate a valid patch for this testcase.
