Description Scot Hetzel 2007-06-21 17:40:12 UTC
When I try and boot a system with the NDIS interface configured as:

ifconfig_ndis0="WPA DHCP"

I see it continuously trying to get a DHCP address, but it fails.  I
found the problem is because wpa_supplicant is not realizing that it
had successfully connected to the wireless network, so it continuously
connects/disconnects.

By starting /usr/sbin/ndis_events, then wpa_supplicant will associate,
and the wireless network is accessible.

hp010# dmesg | grep ndis
ndis0: <Broadcom 802.11b/g WLAN> mem 0xc0204000-0xc0205fff irq 21 at device 2.0 on pci6
ndis0: [ITHREAD]
ndis0: NDIS API version: 5.1
ndis0: using obsoleted if_watchdog interface
ndis0: Ethernet address: 00:14:a5:72:68:64

Fix: Start ndis_events before starting wpa_supplicant for NDIS interfaces.

apply the attached patch which will start ndis_events when the NDIS
interface is set for WPA.

Updated files:

etc/network.subr
etc/rc.d/Makefile

New file

etc/rc.d/ndis_events

Patch attached with submission follows:
How-To-Repeat: set the NDIS interface to "WPA DHCP" and then reboot the system.

Scot,

I've tested wpa_supplicant with an ndis interface and it's working w/o
your patch using 'ifconfig_ndis0="WPA DHCP"'.

ndis0: <Dell Wireless 1490 Dual Band WLAN Mini-Card> mem
0xc8000000-0xc8003fff irq 18 at device 0.0 on pci48

ndis0: Ethernet address: 00:1a:73:ad:a4:67
ndis0: bssid_list failed
ndis0: bssid_list failed
ndis0: link state changed to UP

I have been running this system with a 7.0-PRE amd64 kernel lately and
also haven't seen this problem.

Please check if you can recreate your problem with a recent 7.0
unpatched system.

Thx!

I can recreate the problem with a recent 8.0 system:

FreeBSD hp010 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Wed Feb 13 11:28:36
CST 2008     swhetzel@hp010:/usr/src/sys/amd64/compile/DV8135NR  amd64

When I don't have ndis_event start, then I don't get an IP address
using DHCP.  With it running, I am able to receive an IP address.

ndis0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

I have tested it on 3 different networks (2 - secure, 1 - open).

Two questions; 1) Is this still a problem with the new wireless network 
RC system in 9.0, and 2) I suspect that it is, so please would you give 
this patch a spin? http://www.bayofrum.net/~crees/patches/113915  It's 
mostly based on yours, and cleans up wpa_supplicant a bit.
