Description (Last modified by mentor)

Hello, as far as I know, there was some API change in Linux 2.6.22 release. I have tried the madwifi-ng-current from 11-Aug-2007 (latest). It compiled successfully, but modules wont load. Both the kernel and madwifi driver compiled with the same gcc. 

# uname -srm
Linux 2.6.22.2 i686

# modprobe ath_pci
WARNING: Error inserting ath_hal (/lib/modules/2.6.22.2/net/ath_hal.ko): Invalid module format

FATAL: Error inserting ath_pci (/lib/modules/2.6.22.2/net/ath_pci.ko): Invalid module format

Am I missing something?

  • summary changed from MadWifi seems to be not ready for 2.6.22+ kernel. to Invalid module format - Linux 2.6.22.

At a guess you didn't compile your modules correctly. You need to compile the modules with the same compiler version as you did the kernel. You can check the versions in /proc/version and using 'modinfo'

As wrote in primary description - the compiler version is the same. 

$ cat /proc/version
Linux version 2.6.22.2 (root@y) (gcc version 4.1.2) #1 SMP Sat Aug 11 18:52:40 UTC 2007

# modinfo ath_pci | grep ver
version:        svn r2650
srcversion:     714EE5C7DCF9534B83F0A68
vermagic:       2.6.22.2 SMP mod_unload CORE2 
parm:           countrycode:Override default country code (int)

However, pre-2.6.22 kernels works fine.

What does your kernel log say after you have tried loading the module?

# modprobe -v ath_pci

WARNING: Error inserting ath_hal (/lib/modules/2.6.22.2/net/ath_hal.ko): Invalid module format

From syslog: 

Aug 14 19:20:01 y kernel: ath_hal: module has no symbols (stripped?)
Aug 14 19:20:01 y kernel: wlan: module has no symbols (stripped?)
Aug 14 19:20:01 y kernel: ath_pci: module has no symbols (stripped?)

Other modules works fine, of course..

Yes yes, it must be all our fault.

08/15/07 00:53:22 changed by mentor

Hmmm, so it appears the modules have been stripped. This isn't something that the MadWiFi build process should be doing. How are you compiling?

08/15/07 05:20:00 changed by anonymous

Yes yes, it must be all our fault.

I did not said that :-).

Actually, I have found the problem. The checkinstall utility did not created a correct MadWifi package. Normally it handles "make modules_install" and creates the scripts accordingly. I had not such problem with 0.9.3.1 version, perhaps something new was invented in current MadWifi make script.

Sorry for noise. The ticket might be closed, thanks.
