 Posted: Sat Jun 18, 2005 3:03 pm Post subject: madwifi / wpa_supplicant crashing on shutdown |
 |
|
Hello!
Today I switched my WLAN from WEP to WPA. That was the easy part! Now comes the problem: Each time I shut down my computer, the system will freeze as soon as Gentoo tries to stop my ath0.
The same thing happens when I do a
| Code: | | /etc/init.d/net.ath0 stop |
This behaviour is independant from the way how the interface receives its ip, I tried dhcpcd, udhcpc and static adressing, all the same.
To say again: Everything worked fine when I was still using WEP and madwifi, and everything is working fine now I'm using WPA and madwifi, EXCEPT the whole machine crashes if I attempt to shutdown the ath0 interface. And that's getting on my nerves.
My configuration data:
| Code: |
[ebuild R ] net-wireless/wpa_supplicant-0.3.8 -gsm +readline +ssl 0 kB
[ebuild R ] sys-apps/baselayout-1.11.12-r4 -bootstrap -build -debug -static +unicode 0 kB
[ebuild R ] net-wireless/madwifi-driver-0.1_pre20050420 0 kB
[ebuild R ] net-wireless/madwifi-tools-0.1_pre20050420 0 kB
|
/etc/conf.d/net
| Code: |
...
iface_ath0="dhcp"
dhcpcd_ath0="-N"
modules=( "wpa_supplicant" "!iwconfig" )
wpa_supplicant_ath0="-Dmadwifi"
wpa_timeout_ath0=60
...
|
/etc/conf.d/wpa_supplicant
| Code: |
# List of interfaces
INTERFACES="ath0"
# Common arguments to all wpa_supplicant instances
ARGS="-w"
|
/etc/wpa_supplicant.conf
| Code: |
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
fast_reauth=1
network={
ssid="secret"
proto=WPA
key_mgmt=WPA-PSK
psk="reallysecret"
}
|
So if anyone could help me with this thing, I would be very thankful.

Try this:
| Code: | | rc-update del wpa_supplicant |
You don't need to load it during start up, net will do it for you (usually, I have problem with this once in a while, seems to be related to parallel startup).
Also, I'm running 0.4.2 of wpa_supplicant and it works great (except for one apparently bogus IOCTL warning message). You could try emerging the "unstable" version of it.

@RayDude:
Thanks for the hint, but I never added wpa_supplicant to any runlevel. I will try to use the unstable version as soon as I come home and report back if it works. |

The new version did not make any difference, but your hint helped me work around this somehow:
It seems that wpa_supplicant has to be shut down manually before stopping net.ath0. So I added:
| Code: |
killall wpa_supplicant
|
to my /etc/conf.d/local.stop, so I can shut down my computer without trouble. |

Wow. I don't have that trouble... I wonder what the difference is?

I had the same problem myself, even with the new wpa_supplicant. However, probably the better option would be to setup a predown function within /etc/conf.d/net:
| Code: | predown() {
if [ "${IFACE}" == "ath0" ]; then
killall wpa_supplicant
fi
return 0
} |
Works great now!  Many thanks.
