Roaming Issues Xiaomi AX3600

Bladiebla · July 17, 2021, 4:31pm

Whether this specific firmware behaviour was seen on the stock firmware I can't confirm, I can confirm the behaviour in terms of symptoms weren't there. I ran stock firmware for a couple of weeks before flashing OpenWRT and this issue started with OpenWRT.

On a more humorous note:
I just ran into the issue where DAWN was kicking clients of AP1 (R2100), and AP2 (AX3600) had issues with this behaviour. Client connects to AP1 again, DAWN kicks him off, rince and repeat. My poor kid was trying to watch Netflix, never seen her so frustrated. Turned off the DAWN-kicking, but it does seem to do its job well

I think the esp32 would not send a dhcp request if it would not see the offer. So traffic reaches it.

I agree, these are broadcasts and problems start with direct 1:1 communication.

I can confirm that the esp can not ping and cannot be pinged until some (timeout) magic happens. Length of the timeout looks random to me. Also true for tcp in both directions: esp webserver cannot be reached and esp cannot reach an echo server

Sorry, dont know how to monitor in or out packets on an esp.
Could be a job for my (linux) notebook instead if you think it can shed more light on the situation.

Some new bits of info: I was running this on both routers to monitor the bridge:

while brctl showmacs br-lan | grep 24:a1:60:54:37:d4; do sleep 10; done

Is that the port learning you suspected broken? Looks good to me

Could that be a "normal" linux wlan bridge arp problem? I read linux might do arp spoof protection here. But why does it eventually work then?

brctl showmacs only shows the Linux software FDB. What really happens is the switch's hardware FDB desyncs from the software one.
Try bridge fdb instead. (bridge command is in package ip-bridge)

I dont think it is the hardware bridge port config, but maybe I am misinterpreting this:

My ESP roams from AX1 to AX2 (no MAC change). One line every 10s -> roam takes ~150s.

Edit: add roaming back from ax2 to ax1

Roaming back looks different. It also takes more than 2 minutes, it also switches ports in sync. But syslog is different: no wlan deauth/auth retries, just silence after second DHCP ACK:

There is no self or offload entries so I don't think the switch driver supports FDB dumping.

Another symptom of broken address learning on the CPU port is the switch may flood traffic which should only be sent to CPU, because the switch does not know where it is (This may not happen, depending on how the switch handles unknown destination frames).
To test this, connect 2 LAN clients to the switch. Ping the router on one client and capture ICMP packets on the other.

joba-1 · July 21, 2021, 8:27am

sorry, lots of questions:

Not sure what fdb dumping is good for. Do I need it for roaming?
If I need it, couldn't I see in the source code if it is supported or not?
What do you mean by broken address learning of the CPU port?
Doesn't my logs show port<->adresses mappings of a roaming client work?
What could be the outcome of the proposed lan-lan ping test?
What could be a fix from that outcome(s) to prevent roaming delays?

Thanks

To read the hardware FDB entries. Looks like even bridge fdb cannot read them.

Then you need to ask @robimarko and @Ansuel.

See my first reply in this thread.

Same as 1.

The packet capturing client may see ALL your LAN clients' requests, which is a serious security threat.

Fix the address learning on the CPU port of the switch, either enable it on the hardware, or workaround on the software (Have CPU install static FDB entries to the switch, assisted_learning_on_cpu_port).

joba-1 · July 21, 2021, 3:25pm

Thanks for the infos. Still a bit puzzled how bridge command can see the port switch immediately if this is not communicated, But anyways, in prep for the ping test I looked into tcpdump and monitored a roam with it on both APs.

roaming esp32 from ax1 to ax2:

discover and request broadcasts of esp32 are seen by ax1 (the dhcp server) and ax2
resulting offer is seen on br-lan of ax1 but not on br-lan of ax2
sometimes a request / ack is followed by the offer on ax1 but not seen on ax2 and no effect on esp32

ax1

There's a set of patches given here

which seem to fix this roaming issue.

joba-1 · July 23, 2021, 9:09am

will try asap

just to confirm the procedure I made up myself because patch instructiuons in openwrt wiki didn't work for me:

clone robimarkos repo
checkout restart branch
add the patch files to package/kernel/mac80211/patches/ath11k/
build openwrt as usual
flash firmware
reboot twice (first time doesnt have the changes for some reason)

joba-1 · July 23, 2021, 3:58pm

patches did not apply cleanly.
Tried anyways because source files looked ok.
No change: still roaming delays.
Probably my openwrt build skills still suck too much. I think I’ll wait for a PR…

This is what I built: https://github.com/joba-1/openwrt

foxium2 · July 24, 2021, 5:40am

Just tested the proposed patches and unfortunately it did not resolve the roaming delay problem. Like before, changing the client's MAC after roaming instantly resolves the issue.

Which patch did you have trouble with?

joba-1 · July 24, 2021, 12:09pm

Currently I do a complete rebuild with make j1 V=s to have a decent log.

but IIRC it was

378-mac80211-remove-iwlwifi-specific-workaround-that-bro.patch
[2/2]ath11k-fix-4addr-multicast-packet-tx.patch

I removed them and continued the build since sample checks showed that the changes somehow made it into the compiled source anyways. I'll post once I have the log

These are all the files I changed/added in my fork

package/firmware/ath11k-firmware/Makefile
package/kernel/mac80211/patches/ath11k/378-mac80211-remove-iwlwifi-specific-workaround-that-bro.patch
package/kernel/mac80211/patches/ath11k/801-ath11k-fix-4-addr-tx-failure-for-AP-and-STA-modes.patch
package/kernel/mac80211/patches/ath11k/802-ath11k-small-tx-queue.patch
package/kernel/mac80211/patches/ath11k/803-ath11k-fix-zero-address-in-probe-request.patch
package/kernel/mac80211/patches/ath11k/804-2-2-ath11k-fix-4addr-multicast-packet-tx.patch

1 is just the change of the firmware hash
4 is my own (to avoid oom and have some verification in the kernel.log, that I run the intended firmware

This one is already backported in upstream OpenWrt

Thanks, I removed it from the build. I'll see... make -j1 takes ages

Can you grep for "u16 tcl_metadata;" in your patch directory and see if something else is providing it?

sure. but first, here are all the reject files
