STA stopped working after build r33311

[mikejuni@…]

STA in AR71xx stopped working after build r33311. I've a working self-build on r33311 which works perfectly fine. My setup is like below:

router a router b

pppoe -- ar71xx ap (wds) -- ar71xx sta (wds) + ap

Router b stopped connecting to router somewhere after this build. I tried to disable the ap in router b and it resumes. However it no longer help me extend the range of the wifi hence it is useless.

Please track down in what approximate revision this error was introduced.

It was introduced with r33311, thanks!

[nbd]

But didn't you say you have a working build on r33311?

[mikejuni@…]

All my OpenWRT routers having r33311 and it is working fine.

[nbd]

OK, please find out which version the error first appeared in.

[mikejuni@…]

I use svn co ​svn://svn.openwrt.org/openwrt/trunk/@33325 to checkout @33325 from trunk and build an image. Suspect it is where the problem lies (it is when a new version of netifd is released).

The problem did occur in @33325. I think it is where the problem lies since all patches between 33311 and 33325 aren't so related to ar71xx.

However, when I use scripts/getver.sh it shows that I'm at 33353. Not sure why it isn't 33325...

Let me know if my svn command isn't correct.

[nbd]

please post your network and wireless config

[mikejuni@…]

network configuration

[mikejuni@…]

My wireless config for the non-working router.

[mikejuni@…]

My non-working router's configuration attached.

[nbd]

please try latest trunk

[mikejuni@…]

Doesn't work. Just tried the version with netifd patch (r33595)

[mikejuni@…]

Capture of screen of issue.

[mikejuni@…]

Just some additional information. I've actually 3 Openwrt routers. 1 wndr3700 and 2 ag300h

The wndr3700 is my primary pppoe router.

wndr3700 (wds ap)
| |
ag300h ag300h
(ap + wds sta) (ap + wds sta)

As you can see the configuration is to extend my wndr3700's range.

The configuration of both ag300h is the same (except ip address / macaddr, etc). Only difference is that one is on r33311 and the other one now on r33595.

In the one for r33595 I got the error captured above, and it cannot connect to the wds ap while the other one can. If I remove the "ap" portion of the configuration it can connect to the netgear, but it is useless because I cannot extend the range without "ap" configuration.

[mikejuni@…]

Sorry the above diagram isn't showing it right.

It is something like this:

ag300h (ap + wds sta) --- wndr3700 (wds ap, pppoe) --- ag300h (ap + wds sta)

[mikejuni@…]

This is still bugging me as of today's build (r33669)

[mikejuni@…]

Today I use the "wifi" command manually and it reveals an additional error message:

Failed to set up wpa_supplicant for interface wlan1-1

And I checked ifconfig and noticed that wlan1-1 is not being brought up when using wds sta + ap in the latest builds.

[nbd]

Please show me the contents of /var/run/wpa_supplicant-wlan1-1.conf

Are there no other messages just before "Failed to set up wpa_supplicant for interface wlan1-1"

Does that error message go away if you explicitly do wifi down; wifi?

[mikejuni@…]

Contents of /var/run/wpa_supplicant-wlan1-1.conf

ctrl_interface=/var/run/wpa_supplicant-wlan1-1

Where aa:bb:cc:dd:ee:ff is the BSSID of my WDS AP (The Internet router) and password is the password to the ssid obllntkj30. The full error messages are:

command failed: Device or resource busy (-16)
Configuration file: /var/run/hostapd-phy1.conf
Successfully initialized wpa_supplicant

Failed to connect to hostapd

enable_mac80211(radio1): Failed to set up wpa_supplicant for interface wlan1-1

[mikejuni@…]

I just got some more information, I noticed that apart from wpa_supplicant-wlan1-1.conf, there is also a file wpa_supplicant-wlan1.conf. wlan1 is supposed to be the AP interface. wlan1 do seems to work because I could actually connect to it (but without DHCP address as it is disabled).

Not sure if it is supposed to exist or not.

[mikejuni@…]

Issue still exist. Same error message as of today's build.

[mikejuni@…]

Just want to follow up on this issue, any news? I'm still having this error. It seems like wlan1-1 cannot be brought up causing this, but I'm not sure.

[mikejuni@…]

I've managed to fixed the issue after digging into mac80211.sh for a while and upgrading to latest trunk (with kernel 3.6.8). It seems like there is some issue with the script preventing it from creating 2 interfaces on same PHY without specifying in /etc/config/wireless the ifname for the device.

Once I've put in the the following options:

config wifi-iface
	option device 'radio1'
	option network 'lan'
	option mode 'ap'
	option wds '0'
	option ssid 'ssid'
	option encryption 'psk2+ccmp'
	option key 'password'
	option ifname 'wlan1'
	option disabled 0

config wifi-iface
	option device 'radio1'
	option network 'lan'
	option mode 'sta'
	option ssid 'ssid'
	option encryption 'psk2+ccmp'
	option key 'password'
	option wds '1'
	option ifname 'wlan1-1'
	option bssid 'aa:bb:cc:dd:ee:ff'

Note the "ifname" option (which is not in any documentation) I've managed to bring both the STA and the AP up. However, it doesn't seem like this is a documented option. Also, the script should be able to bring up additional interface if needed.

[nbd]

doesn't seem like an issue in current trunk anymore.
