Logs (dmesg, maybe supplicant and/or hostap) dmesg.txt

I think this might be a supplicant bug. I saw this message in other testing scenarios:

[32m[349951.140828] [0m[33msta5002[0m: 04:f0:21:67:53:95 authenticate with f8:a0:97:44:94:55 at: 1520282299.350687 [32m[349951.141350] [0m[33msta5002[0m: failed to insert STA entry for the AP (error -17)

The supplicant does not know how to work around the EEXIST errno (-17).

Please manually hack in the check for EEXIST. This patch will not apply to upstream supplicant, and I have not re-spun it quite yet, but I think it will be enough for you to make the change:

https://www.spinics.net/lists/hostap/msg04278.html

Have you been able to test with supplicant patched as suggested?

I added the suggested patch. I'm now using latest 4.9 driver, mac80211 backported wt-2017-01-31-0-ge882dff19e7 (same as LEDE-17.01), wpa_supplicant 2016-12-19 (same as LEDE-17.01) and it still does not work. Here is the log:

Some additionnal information: I'm building the driver without DFS support (CONFIG_PACKAGE_ATH_DFS in OpenWrt)

There are no obvious errors in the logs, though there is one failed-to-transmit message. Normally one of those is OK and system recovers, but perhaps in your case it is important?

In this particular case that generated the logs, you are seeing no pkts on air from the ath10k system?

Have you tried testing the same setup without encryption to see if the problem is related to encryption?

In the case you just reported, does the problem always happen on this system, or is it transient?

And finally, please show me output of: cat /sys/kernel/debug/ieee80211/phy0/ath10k/fw_regs

(Adjust for your phy name)

It seems to be related to the encryption. Broadcast traffic is exchanged unencrypted successfully but unicast traffic is sent & received encrypted and does not seem to be decrypted.

It always happens on these systems in this particular location (I guess there are some specific RF conditions in this area). I already changed all the HW several times (electronics, antenna, cables) and I always got the same result.

This is working fine using official ath10k + 802.11s +WPA2-SAE

Those register values must have been taken when the node was inactive? I need to see them in the case where the system is failing.

And, what you describe sounds like key setting issues, which I have previously seen, but in the cases I have debugged, it appears the stack and/or supplicant was doing the wrong thing.

I now suspect the previous 'dmesg' logs were also from a case that was not actively failing? I need to see as complete of a boot log as possible for the case that is actually failing in order to debug this.

Is that log from a working case, or a broken case? If you restart that same node a few times, will it sometimes work and sometimes not? If so, maybe it would be helpful if you could provide one log of broken and one log of the working case so I can compare. Please clearly note any symptoms you see (or do not see) when posting logs so that I know what to look for.

I see no obvious errors in the log you posted above.

This is always broken on this node. In fact it always happens to any node placed on some specific area.

On broken nodes, there is always an asymetric number of streams between RX & TX

And moreover it works fine using ath10k + 802.11s +WPA-SAE on these nodes

You could send me the fw_regs from when the radio is running, that might possibly show some new information.

In the past, similar issues have been related to the on-air packet size. The firmware might send a frame 16 bytes too large or too small, for instance. I have previously debugged this by sending frames of a known size and then looked on-air to see if they were the correct size or not. You might also be able to grab a packet sniff and use wireshark to decode it and look for errors.

If you can somehow reproduce this in a lab (maybe using attenuators?) then it would be a lot easier to debug and fix.

It seems to happen when there is a mismatch on the NSS. For example: side A: iw adhoc0 station dump Station 06:f0:21:31:5b:a1 (on adhoc0) inactive time: 0 ms rx bytes: 6569111 rx packets: 40354 tx bytes: 1604311 tx packets: 5958 tx retries: 0 tx failed: 5953 signal: -46 [-93, -46] dBm signal avg: -46 [-92, -46] dBm tx bitrate: 81.0 MBit/s VHT-MCS 4 40MHz VHT-NSS 1 rx bitrate: 162.0 MBit/s VHT-MCS 4 40MHz VHT-NSS 2 authorized: yes authenticated: yes preamble: long WMM/WME: yes MFP: no TDLS peer: no connected time: 321 seconds

Hello!

This looks quite like the same issue we faced and reported in dec 2016. 100% reproducible with 10.1 firmware and QCA988X.

@oamouroux Please can you check this issue again? Right at the moment when tx begin to fail and second device shows rx bitrate: 6.0 MBit/s (or sometimes rx bitrate: 48.0 MBit/s) iw adhoc0 station dump should show "inactive time:" WITH NEGATIVE VALUE.

After some time, "inactive time:" switches to a normal state, but no traffic can be sent. In OPEN mode this issue with negative "inactive time:" value still exist, but when it switches to a positive state, traffic can go normally through the wireless IBSS link.

Hello, @oamouroux and @greearb .

We've jist triggered this issue in our lab again. Look's like thr problem can be solved (or mitigated) with this parameters: 1) max_nss = 2 in fwcfg if we are using MIMO 2x2 device. 2) beacon_int = 10 in wpa_supplicant if we are using encrypted IBSS.

This issue look's like a beacon interval related, but I can't explain why. IBSS without encryption works fine with any beacon_int parameter.

Also I found a bug in kernel mac80211 code and I want to make a commit later.

Best regards, Lukonin Kirill.

Hello, Ben! @greearb Looks like a found a bug. @oamouroux Please check your issue too.

if we look into fwstats, there will be a strange behavior. Look at the first peer and it's mac address. The first octet behave LIKE A COUNTER! This behavior is reproducible on all 5 nodes in our lab at the same time. I don't know why beacon_int =10 helps in this case. Looks like a bug, really.

3a:ed is the first two octets of the interface mac address and the last two octets of phantom peer. Also there is a strange static RSSI value, hmmmm let's look closer....

printf %x\n 53063 cf47

It's a reverse order of last two octets from ibss interface mac.

So may be there are some bugs with pointers inside the firmware. I don't know. We use firmware ver 10.1-ct-8x-__fH-021-4fa9f30 api 2 features wmi-10.x,txstatus-noack,wmi-10.x-CT,ratemask-CT,get-temp-CT,tx-rc-CT,cust-stats-CT crc32 580c6146

The stats parsing in ath10k is complex and bug prone. The issue could easily be in the driver as well. Do you see this weird first peer only in cases where you are having connectivity issues, or does it happen all the time?

And, the 'beacon int' that fixes this is sending around 100 beacons per second, or did I mis-understand that?

We see this phantom peer all the time, even with AP interface without any sta connected.

But traffic can pass normally through many IBSS hops without visible issues and throughput drops like in this report. So let it be a "Mitigation", but not "Fix". We tried beacon_int = 10 with reboots, interface restarts and didn't trigger this issue, so I confirm that this trick works all the time.

Also, as we can see, this bug can be reproduced with both 10.1 and 10.4 firmwares in IBSS mode. We will check if beacon_int = 10 parameter helps with 10.4 firmware and let you know.

So that peer thing is probably not related to the IBSS bug. Please open a new bug for the peer stats problem.

For the IBSS problem, I cannot think of any reason why sending beacons more often would fix this particular bug report so I don't have any new ideas on how to fix this more properly in the firmware or driver.

@klukonin Earlier you mentioned you forced the system to 2x2 NSS as part of your fix. Are both the 2x2 force and the beacon hack needed, or will one or the other by itself mitigate the problem?

I can confirm that max_nss = 2 with beacon_int = 10 helps. max_nss = 2 alone doesn't help We will try to test only beacon_int = 10 hack and I'll report about the result. May be it will work without 2x2 NSS enforcement.

Ok. I will open a new bug report

Hello @oamouroux and @greearb

He have 100% working recipe of how to trigger this issue and how to avoid it.

1) If we create ibss interface, do sleep 1 and start wpa_supplicant - every node will fail to do traffic exchange with others. Rarely one node can catch a state when it can transmit, but can't receive. TCP acks and small packets can pass, but with very very low throughput, That's why sometimes traffic can pass only in one direction.

2) If we create ibss interface and run wpa_supplicant as fast as we can - this issue does not show itself anymore. It is important that beacon_int parameter should be 10ms.

So may be this issue is not beacon related, but TSF related. I remember a lot of weired things in ath10k and firmware about TSF.

Also, this can be interesting for you, With original 10.2.6 firmware we see how in mesh mode sometimes TSF offset can raise up to 34 days right after we power on our lab. Mesh TSF logic can handle such situations normally, but I'm no sure about IBSS. Anyway, I don't know how to get current TSF offset value in ibss mode.

In some rare RF conditions, no traffic on IBSS connections #18
