mISDN v2 fails on 32bit userspace system with 64bit kernel

mISDN v2 fails on 32bit userspace system with 64bit kernel

[Alexander Naumann]

Hi,

I am running a 64bit kernel (2.6.28.10 or 2.6.30.1) on a 32bit userspace.
I have recognized that mISDN is not working in this mode (if I am using
32/32 mode everything is fine).

Logs tell me that ioctl calls fail.
It seems that they are not compatible running in mix mode (I did not
test pur 64 bit mode).


I have used mISDN-drivers (v2) from kernel (2.6.28.10, 2.6.30 and
2.6.31.2) and tried to start mISDNuser tools:

A socket connection is established but every socket connection through
ioctl is going to fail.

"Oct 14 14:51:20 localhost kernel: ioctl32(misdnportinfo:8098): Unknown cmd fd(3) cmd(80044943){t:'I';sz:4} arg(ffa7b5b4) on socket:[107121]"

At the isdn4linux mailing list I have read some months ago that it is also not working with a pur 64 bit system.

Is anybody able and willing to work on this problem?

Thanks for help

Alex
