Hi Cedric!
When we run input04 on RHEL 5.11GA and 6.7GA, it still fails. It gives
error message like this:
input04 0 TINFO : Found uinput dev at /dev/uinput
input04 0 TINFO : Unexpected ev type=0 code=0 value=0
input04 1 TFAIL : input04.c:65: Data received /dev/inputX
I think that this failure is because kernel sends empty events. i.e
If we only send EV_SYN to input device, nothing should be received in
/dev/input/eventX.
Actually, data is received in /dev/input/eventX. This investigation
shows that it may be
improved by following patch: 'commit 4369c64c79a2 ("Input: Send events
one packet at a time")'.
Could tell me the real reason for the case failure. I'm just not
familiar enough with the code.
Regards,
Xiao Yang

Hi!
I'm afraid that cedric@suse.com no longer works as Cedric was here only
for his internship. I can try to ask our kernel developers that he
worked on these testcases with though.

Thanks.
I want to know the part of kernel resulting in the testcase failure.

I have runned these test cases in RHEL5.11GA and RHEL6.8Beta.
When above patch is not applied, input/04 and input/05 failed with the following messages.
-----------------------------------------------------------------------------------------
[root@linux6 input]# ./input04
input04 0 TINFO : Found uinput dev at /dev/uinput
input04 0 TINFO : Unexpected ev type=0 code=0 value=0
input04 1 TFAIL : input04.c:65: Data received /dev/inputX
[root@linux6 input]# ./input05
input05 0 TINFO : Found uinput dev at /dev/uinput
input05 0 TINFO : Unexpected ev type=0 code=0 value=0
input05 1 TFAIL : input05.c:69: Data received in eventX
When above patch is applied, input/04 and input/05 passed with the following messages.
-----------------------------------------------------------------------------------------
[root@linux6 input]# ./input04
input04 0 TINFO : Found uinput dev at /dev/uinput
input04 1 TPASS : No data received in /dev/inputX
[root@linux6 input]# ./input05
input05 0 TINFO : Found uinput dev at /dev/uinput
input05 1 TPASS : No data received in eventX
So, i think the above patch fixes this bug.
