hostap-0.6.4 + ath5k

Tue Oct 7 17:59:27 PDT 2008

Hi,all
I deployed hostap0.6.4 + ath5k, and got 2 problems.

My env is: kernel 2.6.26, hostap 0.6.4
compat-wireless-old-2008-10-06.tar.bz2
libnl-1.0-pre8.tar.tar

1. when make wireless souce tree, there are several
WARNINGs:
  Building modules, stage 2.

And ath5k.ko can not be insmod properly:
[root at telnetserver ath5k]# insmod ath5k.ko
insmod: error inserting 'ath5k.ko': -1 Unknown symbol
in module
the "dmesg" shows:
ath5k: Unknown symbol ieee80211_hdrlen

So what can i do for this problem.

2. When I insmod the ath5k.ko from the linux kernel 
2.6.26, the wlan0 can work well.
But the hostapd can not work:

[root at telnetserver hostapd]# ./hostapd -dd
./hostapd.conf
Configuration file: ./hostapd.conf
ctrl_interface_group=0
nl80211 not found.
nl80211 driver initialization failed.
wlan0: Unable to setup interface.
Flushing old station entries
Deauthenticate all stations
rmdir[ctrl_interface]: No such file or directory
Could not remove VLAN iface: vlan1: Illegal seek
Could not remove VLAN iface: vlan2: Illegal seek
Could not remove VLAN iface: vlan3: Illegal seek
Could not remove VLAN iface: guest: Illegal seek

Though i haven't patch the ath5k's driver from linux
kernel 2.6.26 for AP mode, hostapd can not run as AP
mode indeed. 
But i think this problem happened when nl80211 was 
initialized (function i802_init) and AP mode will be
set later, not at this time.

There are some troubles on my deployment "hostap + 
nl80211 + ath5k".Thanks for ur kindly response.

Best regards,
