Re: [PD] [hid] crashing with segmentation fault

24 Jan 2006

      Ok, still haven't had a moment to get my Debian going again, but I

thought of something else.  I updated make-arrays-from-input.h.pl to

generate a ev_syn array of 512 items.  This should hopefully prevent

the segfaults on Linux 2.6 kernels until I figure out a better way to

do this.

Hi Hans,
I just tried replacing the line you told me in hid_linux.c and it

doesn't work. External compiles well but it still segfaults with

exactly the same error.
Since I don't understand much C programming, I just replaced what you

said blindly...
Good luck with your PowerBook anyway (-;

Ok, while working on this, my Linux install went down in flames.  I

guess "unstable" was actually unstable this time.  After a few long

fscks, I am back on Mac OS X, but not yet on Debian.  Anyway, the

Linux  2.6 sync events are not used by [hid] and are not HID events,

but  generated by the Linux kernel, so they'll be eventually removed

so that  everything is the same across platform.
For now, try replacing this line in hid_linux.c (line 180):
    else
with this:
    else if ( event_type != EV_SYN )
Sorry, I can't test it myself until I fix Debian on my PowerBook.

Arg...

Hi Haans Christopher,
In fact, it seems that both the keyboard and the mouse are making

[hid] crash. Some time ago, when the touchpad used to work, I

remember  it made it crash as well and I'm quite sure it gave

syn_report  messages as well...
By the way: [hid] doesn't crash on my desktop which is Debian

testing  as well... I'll check the output to see if syn_report

messages are  present or not.

Are you able to narrow down which device is causing it?  Looks like

  syn_report messages are the culprit.  I don't have a device that

 outputs syn_report events (IIRC).
I'll look at this today.

Hi Hans, hi list,
I just got back to trying to make [hid] work on my laptop and I

still  can't...
[hid] is the latest from CVS (Friday, January 6th 2006) and still

 gives segmentation faults.
My machine is a PC running Debian unstable with 2.6.14.
Here's more detail:
I have 3 HID peripherals on the machine:

/dev/input/event0 :: Keyboard
/dev/input/event1 :: Touchpad
/dev/input/event2 :: USB Mouse

"$ hexdump /dev/input/event1" doesn't output anything so I assume

the  touchpad doesn't send info well. Let's forget about that for

now.
"$ hexdump /dev/input/event0"
"$ hexdump /dev/input/event2"
Both output hex. dataflow.
The output from [print( sent to [hid] compiled in debug mode for

the   keyboard is printKeyboard.txt. printTouchpad.txt and

printMouse.txt   are the outputs from the 2 other peripherals.
The 2 other files (printSegFaultKeyboard.txt and

printSegFaultMouse.txt)  is the stderr from the two peripherals

that   make [hid] crash. Touchpad doesn't seem to send anything.
I suspect the problem being similar to what Gerda experienced in:

 http://lists.puredata.info/pipermail/pd-list/2005-08/030339.html
Do you know where the problem may come from?
Do you need more output from anything?
