grsecurity forums

I am using the latest release of grsecurity (2.1.11) on the 2.6.24.5 kernel using Ubuntu 8.04. I'm having no success setting up my wireless network. When I try to manually configure my network settings, 'Wireless Connection' isn't even an option, but I have no clue why. When I boot without the grsecurity patches, I don't have this problem. I lshw'ed on the cmdline to try to diagnose the problem, but to no avail. I did notice some differences, though. This is what I found:

Without the grsec patches:

Any ideas?

On the commandline you can get information with iwconfig and ifconfig for wireless connections (produces readable and easily reproducable output).
Since we are here talking about grsecurity don't forget to check the logs or dmesg.

Wireless works perfectly with grsecurity here (currently both an atheros ar5007 and an iwl3945, I can't remember having any trouble with an old ipw2100).

Since it is an ipw2200:
- what happens when you (manually) load the driver using modprobe?
- is the firmware correctly uploaded?
- are any programms reporting trouble with (dmesg)?

I suspect you will find something like a message about some programm that has been killed for trying anything your configuration won't allow.

You should realise both grsecurity 2.1.11 as the 2.6.24.5 kernel are old and Ubuntu 8.04 has been succeeded by version 8.10.
Are you using precompiled kernels? If not you should try to switch to the latest test-patches.
