hostapd: FT over DS leads into nl80211: NL80211_ATTR_STA_VLAN error #16880

Open NilsRo opened 2 weeks ago

Describe the bug

Technically FT over DS should be better as the src AP connects to the target AP over LAN. https://www.cisco.com/c/dam/en/us/td/docs/wireless/controller/technotes/80211r-ft/b-80211r-dg.html

Activating this in OpenWRT leads into an nl80211: NL80211_ATTR_STA_VLAN error but it seems working mostly. So I do not now if this error is a false-positive.

I tried also to set the following to move the preauth to another interface but it does not change the behavior. This error is also mentioned mostly in OpenWRT forum that FT over DS is broken.

        option rsn_preauth '1'
        option rsn_preauth_interface 'eth1.1'

FT works sometimes but the log is spammed with the errors above. Also I am not sure if this shows a real error that FT is not working like expected.

Expected behaviour

No response

Additional info

No error, FT working fine. Happens also with OpenWrt SNAPSHOT r27700-170ecbecfc
