[LTP] Failure of syscalls in kernel version 3.4

[LTP] Failure of syscalls in kernel version 3.4

[-- Attachment #1.1: Type: text/plain, Size: 2314 bytes --]

Hi,
I am currently using ltp-full-20110915.bz2.
When I switched to  kernel 3.4(from kernel 3.0)  then these syscalls ltp are failing.

[1]. get_robust_list01
get_robust_list01    1  TPASS  :  get_robust_list failed as expected with EFAULT
get_robust_list01    2  TPASS  :  get_robust_list failed as expected with EFAULT
get_robust_list01    3  TPASS  :  get_robust_list failed as expected with ESRCH
get_robust_list01    4  TFAIL  :  get_robust_list succeeded unexpectedly
get_robust_list01    5  TPASS  :  get_robust_list succeeded


[2]. gettimeofday02

gettimeofday02    0  TINFO  :  checking if gettimeofday is monotonous, takes 30s

gettimeofday02    1  TFAIL  :  Time is going backwards: old 946



[3]. lseek03

lseek03     1  TFAIL  :  lseek(tfile_16887, 1, 4) Failed, errno=6 No such device or address, expected 22(EINVAL)

lseek03     2  TPASS  :  lseek(tfile_16887, 1, -1) Failed, errno=22 : Invalid argument

lseek03     3  TPASS  :  lseek(tfile_16887, 1, 7) Failed, errno=22 : Invalid argument



[4]. readlink03

readlink03    1  TPASS  :  readlink(), No Search permissions to process, returned errno 13

readlink03    2  TPASS  :  readlink(), No Search permissions to process, returned errno 13

readlink03    3  TPASS  :  readlink(), Buffer size is not positive, returned errno 22

readlink03    4  TPASS  :  readlink(), Buffer size is not positive, returned errno 22

readlink03    5  TPASS  :  readlink(), File is not symbolic link, returned errno 22

readlink03    6  TPASS  :  readlink(), File is not symbolic link, returned errno 22

readlink03    7  TPASS  :  readlink(), Symlink path too long, returned errno 36

readlink03    8  TPASS  :  readlink(), Symlink path too long, returned errno 36

readlink03    9  TFAIL  :  readlink() failed, Symlink Pathname is empty, errno=2, expected errno=22



[5] shmat01

shmat01     1  TFAIL  :  shmat call failed: TEST_ERRNO=EINVAL(22): Invalid argument



[6] sysctl01

sysctl01    1  TFAIL  :  sysctl(2) failed unexpectedly errno:38

sysctl01    2  TFAIL  :  sysctl(2) failed unexpectedly errno:38

sysctl01    3  TFAIL  :  sysctl(2) failed unexpectedly errno:38



any idea why these testcases are failing now?.

How can I resolve it?.



Best Regards,

Om Prakash Pal

I'd suggest you try latest LTP from git. Some of these failures should be already fixed.
(Latest I ran was kernel 3.3 and it ran fine for the ones you listed)

38 is ENOSYS, this works only if your kernel supports it (CONFIG_SYSCTL=y).

Kernel implementation moved forward, your LTP is almost year old.

Re: [LTP] Failure of syscalls in kernel version 3.4

[Om Prakash PAL]

Hi Jan,
Thanks for your reply.
I have moved to latest LTP.
After that some test cases are failing like:
 
[1].
 shmat01
 shmat01     1  TFAIL  :  shmat call failed: TEST_ERRNO=EINVAL(22): Invalid argument


any idea about this one?.

Best Regards,
Om Prakash Pal

I could reproduce this issue with following change:
----------------------------------------------------
diff --git a/testcases/kernel/syscalls/ipc/shmat/shmat01.c b/testcases/kernel/syscalls/ipc/shmat/shmat01.c
index 7c68459..5d6e79c 100644
--- a/testcases/kernel/syscalls/ipc/shmat/shmat01.c
+++ b/testcases/kernel/syscalls/ipc/shmat/shmat01.c
@@ -271,6 +271,8 @@ void setup(void)
                tst_brkm(TBROK, cleanup, "Couldn't detach shared memory");
        }
 
+        printf(" ");
+
        /* some architectures (e.g. parisc) are strange, so better always align to
         * next SHMLBA address. */
        base_addr =
----------------------------------------------------

What happens in setup() is that shared memory is attached/detached, and that
address is used in the rest of the test. In case above glibc needs
extra page and mmaps one at same exact spot:
----------------------------------------------------
shmget(0x61008d5b, 4, IPC_CREAT|IPC_EXCL|0600) = 2260995
shmat(2260995, 0, 0)                    = ?
shmdt(0x7ffabd573000)                   = 0
fstat(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7ffabd573000
shmat(2260995, 0x7ffabd573000, 0)       = -1 EINVAL (Invalid argument)
----------------------------------------------------

I'm assuming something like this happens in your case too,
output from "strace ./shmat01" would be helpful.

Jan

This is fixed by commit https://github.com/linux-test-project/ltp/commit/dc9df862a95db96b7046623659ceaf911a583ce7


and so on, if you meet further FAIL like these, please use upstream version of LTP,
you can get from git://github.com/linux-test-project/ltp.git .
And, if the upstream version also has problems, please feel free to send a patch here.
