[LTP] [PATCH] syscalls/shmctl: Using TERRNO to macth errno

[zhaogongyi]

Hi Li,

Yes, I find the problem in my testing of qemu with kernel version 4.4 and the config is vexpress_defconfig.
Specifically as follow:

tst_test.c:1294: TINFO: Timeout per run is 0h 05m 00s
shmctl04.c:119: TINFO: Test SHM_STAT_ANY with nobody user
TST_RET: 0 SHM_STAT_ANY: 15
shmctl04.c:134: TFAIL: SHM_INFO haven't returned a valid index: EINVAL (22)
shmctl04.c:150: TFAIL: Counted used = 0, used_ids = 1
shmctl04.c:85: TPASS: used_ids = 1
shmctl04.c:92: TPASS: shm_rss = 0
shmctl04.c:99: TPASS: shm_swp = 0
shmctl04.c:106: TPASS: shm_tot = 1
shmctl04.c:119: TINFO: Test SHM_STAT_ANY with root user
TST_RET: 0 SHM_STAT_ANY: 15
shmctl04.c:134: TFAIL: SHM_INFO haven't returned a valid index: EINVAL (22)
shmctl04.c:150: TFAIL: Counted used = 0, used_ids = 1
shmctl04.c:85: TPASS: used_ids = 1
shmctl04.c:92: TPASS: shm_rss = 0
shmctl04.c:99: TPASS: shm_swp = 0
shmctl04.c:106: TPASS: shm_tot = 1

Summary:
passed   8
failed   4
broken   0
skipped  0
warnings 0


I will analysis the root cause of fail later.

Thanks!

Best Regards,
Gongyi

Hi Li,

Actually, I have no effective tools to find out all of this type problems.

Indeed, the wrong usage of TTERRNO you find mostly occurred in bad code logic.
That's hard to correct them in an automatic way.
