Re: uinput oopses and bugs

HI Aristeu

first, please keep the mailing list on Cc. two reasons: first, I may not
be able to answer other questions; second, other people may have the
same problems you do and this discussion can be useful for them.

Last time the mail from the list bounced again although I've explicitely
subscribed to linux-input@vger.kernel.org but nevermind

Still the EV_FF makes EV_LED and EV_SND not working.

will work on that next.

Hope the reproducer works for you, it's a bit clumsy written
but I hope it's useful to track this LED and SND disabling by
FF

There is also a still issue with segfault and unkillable driver.
I upload custom FF effect, driver segfaults but doesn't exit
and becomes zombie

please test the attached patch

The patch now avoids the zombie lockup coming from segmentation
fault.  Thanks a lot, that is great step forward!

However it's still not clear to me why do I get this segmentation
fault when I try to upload a block of FF_CUSTOM sample data.
I made my code mainly from looking at the kernel source without
having any example - anyone on the list can point link to some small
code example?

in uinput-zombie, I've prepared the data in application, ioctl'ed them
to uinput event device and the uinput driver segfaults when
it tries to read the portion of  FF_CUSTOM data.

Best regards, Davor
