Hostapd crashing after a few applies

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello everyone,
i have a master OpenWRT build from today 2 pm. It is running on a 8Devices Carambola2 using ath79. When i apply configuration for Wifi with wifi or /etc/config/network reload, hostapd is crashing. This usually happens after the 5th attempt without changing the config in /etc/config/wireless. When i reboot the device everything is running perfectly.

cat /etc/config/wireless

config wifi-device 'radio0'
	option type 'mac80211'
	option hwmode '11g'
	option path 'platform/ahb/18100000.wmac'
	option htmode 'HT20'
	option noscan '1'
	option legacy_rates '0'
	option country 'DE'
	option channel '11'
	option txpower '20'
	option disabled '0'
	option log_level '1'

config wifi-iface 'wifinet0'
	option mode 'ap'
	option network 'lan'
	option device 'radio0'
	option ssid '0021-test-1-24'
	option disabled '0'
	option hidden '0'
	option encryption 'psk2'
	option key 'wireless123'

config wifi-iface 'wifinet1'
	option mode 'ap'
	option network 'lan'
	option device 'radio0'
	option ssid '0021-test-2-24'
	option disabled '0'
	option hidden '0'
	option encryption 'psk2'
	option key 'wireless123'

config wifi-iface 'wifinet2'
	option mode 'ap'
	option network 'lan'
	option device 'radio0'
	option ssid '0021-test-3-24'
	option disabled '0'
	option hidden '0'
	option encryption 'psk2'
	option key 'wireless123'

Does someone have an idea what I could still control or what is causing this problem.

Many thanks for the effort in advance

Where on Earth today at 2pm? :smiley:

  • Notice anything?
  • Perhaps it would help if you can explain why you're editing the wireless config; and then proceed to reload the network?
  • It may also be helpful if you explain why you perform the action multiple times
  • It may also help to explain why you do this without making changes

This statement was a bit too much :see_no_evil: sorry

When you use /etc/init.d/network reload it will also trigger wifi

reload_service() {
	local rv=0

	init_switch
	ubus call network reload || rv=1
	/sbin/wifi reload_legacy
	return $rv
}

It is not important if you try to do it in a few minutes or in a few hours. And I think it should work every time no matter how often I have already changed settings. I just found out that it occurs after a after a certain number of attempts during troubleshooting.

Same here. During troubleshooting I found out that I have no need to change the settings to reproduce this error.

These are just the minimum requirements to reproduce this behavior.

Before that I usually tried to enable and disable the radio or a specific wifi interface.

  • Does that mean you don't wish to tell us why you hit the button - even when you don't have to edit anything?
  • I'm not sure why you showed the script
  • I was more so seeking your personal motive/use case that discovered it

:open_mouth: Ummmm...OK...I guess that does mean you don't wish to tell us.

Ummmm...OK... :confused:

Well, all I can suggest is wait 'til the next Snapshot.

I did a master build so I can experiment a bit with 802.11k, 802.11v and DAWN and luci-app-dawn.

I tested different settings and just played arround. That is why i applied the configuration so often. And after a few settings i wondered why the wifi interface didn't come up. At first I thought the configuration was wrong and I reset the last change. But after saving again, the wifi interface still did not come up. After rebooting the device every thing was working great till i had made a few changes again.

Then i tried to find out why the wifi interface sometimes doesn't start anymore. Until I found out that it is enough to run the wifi command a few times, with and without making changes to the configuration.

I downloaded the latest development snapshot today and tried this without any extra packages and with the basic wifi configuration. After a few times (5 to 6) running wifi the crash appears. Rebooting the device and anything is working great again. Then i installed LuCI. I changed the SSID a few times (just for testing) via LuCI and after the 5th or 6th attempt the crash appears again. After rebooting everything was working great again.

Then i installed a stable release build v19.07.4 and made the same test again. Everything is okay with v19.07.4. I made about 10 attempts on changing something. The wifi interface always started again.

I made this topic because i want to help find out why this behavior occurs but i don't know what to do after increasing the log level of hostapd.

Maybe there is an idea what i can do to find out more about the crash.
