I get this output from "hostapd -d" (running on a Verdin AM62 with IW416): nl80211: kernel reports: Match already configured nl80211: Register frame command failed (type=176): ret=-114 (Operation already in progress) nl80211: Register frame match - hexdump(len=0): [NULL] If I run the same hostapd on v6.7 without the patches, the AP is started with no issues. Is there anything else that should be done in order to test this? Rafael

I re-applied the pach on top of tag v6.7.2 to make sure we're seeing exactly the same thing. At first, the behavior I was seeing was exactly the same I reported before. Upon starting hostapd with our basic example configuration, it would fail to start the AP with the error: nl80211: kernel reports: Match already configured nl80211: Could not configure driver mode After some investigation of what could cause this error, I found out that it was connman that was interfering with this somehow. After killing the connman service, the AP would start correctly. I want to point out that this behavior is different from the unpatched driver. With that one we don't need to kill connman in order to start the AP with hostapd. After seeing the AP starting up, I did a quick series of tests (Toradex Verdin AM62 with 1GB of RAM and two antennas connected via SMA adapter): 1) AP test: I was able to use the simple AP configuration with two clients connected simultaneously. I executed simple ping tests and also a quick run of iperf3 with the following results [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 16.8 MBytes 14.1 Mbits/sec 11 sender [ 5] 0.00-10.05 sec 16.4 MBytes 13.7 Mbits/sec receiver I repeated the same iperf3 test several times with similar results. Comparing the iperf3 results with what I get on the unpatched driver (v6.7.2), there seems to be a difference in average bandwidth: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 20.2 MBytes 17.0 Mbits/sec 0 sender [ 5] 0.00-10.04 sec 19.7 MBytes 16.4 Mbits/sec receiver 2) Client test: I also executed a similar test but now with the AM62 as the client. It was possible to connect to an AP and do the ping tests without problems. The iperf3 results are in line with what we see on the AP: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 19.3 MBytes 16.2 Mbits/sec 32 sender [ 5] 0.00-10.01 sec 19.0 MBytes 15.9 Mbits/sec receiver Comparing with the unpatched v6.7.2 we can also see a difference: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 23.4 MBytes 19.6 Mbits/sec 0 sender [ 5] 0.00-10.01 sec 20.7 MBytes 17.3 Mbits/sec receiver 3) Simple WPA3 AP test: to finish this round of tests, I started an AP with a configuration enabling SAE. The AP was started successfully and I could connect a client with wpa_supplicant. Ping tests were also succesful here. The iperf3 result shows a bigger bandwidth than all the previous tests: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 20.6 MBytes 17.3 Mbits/sec 35 sender [ 5] 0.00-10.04 sec 19.8 MBytes 16.6 Mbits/sec receiver To summarize the results, it seems that the basic functionality is working and also WPA3 support. We have a different behavior when starting the AP, where now we need to stop connman (blacklisting the uap0 interface will probably also work) beforehand. I don't know if the bandwidth results are something to be worried about, I saw some variation between iperf3 runs, but the results I posted show an average of what I was seeing. Rafael

For i.MX + SDIO IW416, it needs to install following two files for client and AP mode to "/lib/systemd/network" for systemd-networkd: <<Client mode: 80-wifi-station.network>> [Match] Type=wlan WLANInterfaceType=station [Network] DHCP=yes <<AP mode: 80-wifi-ap.network>> [Match] Type=wlan WLANInterfaceType=ap [Network] Address=192.168.100.1/24 DHCPServer=yes [DHCPServer] PoolOffset=100 PoolSize=20 I think this is not related to driver.

The issue I reported is that the kernel with the patch is behaving differently when compared to the kernel without the patch. I kept all the test conditions the same, just replacing the kernel. It seems that you can reproduce this on your end using NetworkManager.

Systemd-networkd is only for address assignment, so it won't affect the test of AP mode. However, Ubuntu Network Manager will affect AP mode test, so it needs to stop it before running hostapd. David

On our reference images we have a simple service that starts hostapd directly. We also have connman running by default and it's responsible for setting up the other interfaces (ethernet, wifi client). In this setup, we previously were able to just start the hostapd service and the AP would start working. Now with the patch, connman seems to be doing something with the interface that causes the AP to fail starting. For reference, this is the simple AP service we start: [Unit] Description=Hostapd IEEE 802.11 AP, IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator Requires=enable-wifi.service [Service] Type=forking PIDFile=/run/hostapd.pid ExecStart=/usr/sbin/hostapd /etc/hostapd-tdx-demo-img.conf -P /run/hostapd.pid -B [Install] WantedBy=multi-user.target If you want to replicate this behavior on your side, probably just building connman with yocto and adding it to your image is enough. After enabling connman to start at boot time, you can try to start hostapd manually. Regards, Rafael

Without host mlme, management packet filter of AP mode is the same as client mode. Authentication/Association packets are handled by firmware and once if station is connected, firmware will send station connection event to driver. So you can still start wpa_supplicant and hostapd on uap0 at same time. However, this is not correct setting and usage. 2. With host mlme, management packet filter of AP mode is not the same as client mode. Authentication/Association packets are sent to hostapd, so cfg80211 won't allow wpa_supplicant and hostapd run on uap0 at same time (different management packet filter). I think no matter with or without patch v8, setting of connman for uap0 should not be client mode. Setting of connman for uap0 should be ap mode or bypass to control it as client mode. The behavior of patch v8 is correct and it can avoid user to run wpa_supplicant and hostapd on AP wireless interface at same time. There is no side effect of patch v8 for this behavior. I also found document from Toradex about how to run connman for AP mode: https://developer.toradex.com/linux-bsp/application-development/networking-connectivity/how-to-setup-wi-fi-access-point-mode-linux/ Please check section 8: Enable and start hostapd service: First, make sure to blacklist the uap0 interface on connmanctl by adding it to NetworkInterfaceBlacklist at connman/main.conf. I think to block uap0 from connman is correct way to run hostapd on uap0. David

Host MLME is disabled in this specific combination, I just wanted to verify that no obvious regression was introduced, and I was not able to see any difference in behavior nor in performances.
