hisax isdn network broken

Same problem here with linux-image-2.6.24-19-generic; isdn networking does not work at all since ipppX interfaces can't be configured.

The patch mentioned above is part of the stable kernel series (included in 2.6.24.6) and helps for me.

Hi Guys,

Thanks for the reference to the upstream patch. Just for your information, the patch referenced is already in the upcoming Intrepid Ibex 8.10 Ubuntu kernel. If you'd like to test the latest Alpha for the upcoming Intrepid release, more information can be found at http://www.ubuntu.com/testing.

I've listed the upstream git commit id for this patch below. I'll also approve the Hardy nomination for the kernel team to consider backporting this patch. Thanks.

    [ISDN]: Do not validate ISDN net device address prior to interface-up

    Commit bada339 (Validate device addr prior to interface-up) caused a regression
    in the ISDN network code, see: http://bugzilla.kernel.org/show_bug.cgi?id=9923
    The trivial fix is to remove the pointer to eth_validate_addr() in the
    net_device struct in isdn_net_init().

Hi,

I've added the patch and built the linux-kernel package - you can download the packages from my PPA at: https://launchpad.net/~colin-king/+archive

Add the following lines to your apt sources.list:

deb http://ppa.launchpad.net/colin-king/ubuntu hardy main
deb-src http://ppa.launchpad.net/colin-king/ubuntu hardy main

Then run the command:

sudo apt-get update

Alternatively, follow the instructions at: https://help.ubuntu.com/8.04/add-applications/C/extra-repositories-adding.html

If you can test this package and let me know if it works, then I can add this patch into the hardy as a Stable Release Update (SRU).

Thanks, Colin

It's working for me

thanx Peter

SRU justification:

Impact: ISDN networking does not work at all because ipppX interfaces
cannot be configured - c.f.
http://bugzilla.kernel.org/show_bug.cgi?id=9923

The patch attached is straight forward 1 line change in the form of an
upstream cherry pick of commit d2dcba612b357a4687843ad4f46629d219233fd7
to not validate the ISDN net device address prior to interface-up by
nullifying the pointer validate_addr.

Testcase: Without the patch, ISDN ipppX interfaces cannot be configured
and ISDN does not work. With the patch, ISDN now works.
