AR9271 stops receiving packets after several seconds to a several hours on monitor mode on any given channel, on every OS and card

[melyux]

Both the current and previous version seem to have the issue. After anywhere from 20 seconds to 3 hours or so of being in monitor mode, the interface stops receiving packets. It seems to die more quickly during busier times when it receives more packets. The ifconfig count stops increasing, and the driver debug debug_fs numbers also become static. The only way to get it to receive again is to change the channel (changing to another channel and then immediately switching back works; I don't know whether the card is slipping to a non-WiFi frequency or something, since iw still reports it as being on the same frequency as it was before, and it makes no changes to the frequency if it thinks the card is already on the channel that is specified). It doesn't seem to be able to stay on one channel for very long.

I've tried this with several Atheros AR9271 chipset cards, like the ALFA AWUS036NHA and TP-Link TL-WN722N. They all have the same issue. I've tried it on Debian, Kali, Raspbian, Raspbian Lite, and Arch, and I've gotten identical behavior. I've tried a powered USB hub, an unpowered hub, and no hub at all. I've tried it on a MacBook, a Virtual Machine, a Mac Mini, a Raspberry Pi, and a Pi Zero. I've tried it with all sorts of different antenna. I've tried power supplies of various amperages. I've tried it with all other processes killed. I've switched intermediary USB cables around and gotten rid of them altogether. Power save is off in both module parameters and in iw.

dmesg and syslog show no errors or events when this happens. The packets just silently stop coming in until the channel is changed. The activity LED on the cards stop blinking and turn solid. Other non-Atheros wireless adapters work fine on every system for weeks on an end without stopping packet reception.

To reproduce, put any AR9271 wireless card into monitor mode and take it into a relatively crowded area. Don't change the channel (or do it, it might die faster if you do, it's Russian roulette). It may take seconds or hours, but it is guaranteed to stop receiving packets indefinitely after a certain point within the day.

@erikarn , hm... should we do some periodic recalibration?

[erikarn]

lol uhm, yes? :)

Are you telling me ath9k_htc is not doing any periodic calibration either in firmware or in the host side? I expected the host side is doing some stuff

Not 100% sure if we are not doing. But is sounds like not, at least not for monitoring mode.

[erikarn]

Yes, we should be, even in monitor mode.

Interesting. I have had similar effects when being in monitor mode and having set fcsfail, i.e. frames with wrong checksum are also forwarded.

I could reproduce this by using my EZ-Wifibroadcast distribution, enabling fcsfail in monitor mode and then running it near sensitivity limit, so that there are something like 50% of wrong checksum frames being received. Then sometimes, it would just stop receiving packets, like you described, no more ifconfig packets/bytes updates.

Never tried to switch channel though when that happened. But I remember ifconfig down/up didn't work.

Without FCS Fail, this never happened, have been running these cards for several days in monitor mode constantly receiving ~700 1024 byte frames per second.

[olerem]

@melikyuksel can check if fcsfail ist set on you system?

[melyux]

@olerem The fcsfail flag is not set. Just to check, I turned it on for both AR9271 cards, and both still eventually stopped within 30 minutes (lots of traffic at the moment). I turned it off, and both again stopped receiving packets again within the next hour.

I'm testing all this on fresh installations, and that flag is turned off by default when using both iw and airmon-ng with AR9271. Doesn't seem to make a difference for AR9271 like it does for EZ-Wifibroadcast.

[rodizio1]

Not sure what the default is, I explicitly set it with iw dev wlan0 set monitor none. (Since I don't trust any "iw" or "iwconfig" outputs ...)

When I use iw dev wlan0 set monitor fcsfail it sooner or later stops receiving frames when too much "garbage" frames come in.

Edit: I'm also using AR9271 cards, same as you, TPLink 722 and Alfa AWUSH036NHA.

[melyux]

I suspect that your cards would also stop receiving frames irregardless of fscfail if you were in a crowded enough area. I might be wrong and you might already be though. I've noticed that the more packets the card is seeing, the sooner it fails. Turning on fcsfail probably just increases the number of processed packets and leads to failure. In my case, I'm in such a crowded area that the card fails even without setting that flag on.

[olerem]

in this case, after monitoring is stalled, ifconfig will show you identical or similar amount of packages

[olerem]

I started monitore test: ifconfig wlxa0f3c1187553 up airmon-ng start wlxa0f3c1187553 6 tcpdump -ni mon0

Currently it is running one hour.

[melyux]

I left two running overnight as well (and they didn't stall, because they never stall overnight for some reason), and one just stalled at 5,138,158 RX packets (1.0 GiB), while the other stalled 5 hours later at 13,240,931 RX packets (2.3 GiB) so far. Is there some way to debug the situation when they stall? The ath9k_htc debug system itself show no difference for when it's running vs. when it's stalled.

[rodizio1]

I suspect that your cards would also stop receiving frames irregardless of fscfail if you were in a crowded enough area. I might be wrong and you might already be though.

I have tested it with detached antennas on the receiving wifi sticks (PCB Antennas on 722N also disabled) all they could hear was the packets coming from my transmitting wifi sticks (i.e. the videostream).

I've noticed that the more packets the card is seeing, the sooner it fails. Turning on fcsfail probably just increases the number of processed packets and leads to failure. In my case, I'm in such a crowded area that the card fails even without setting that flag on.

This was not the case with my tests, the transmitting stick sends something around 700 frames per second. When being near, lost frames or frames with failed FCS are almost zero, maybe one per 5 minutes or so. Then it runs for days. When going to the edge of reception, there are actually less frames being received as some are completely lost. I also noticed that this 'stall' happens quicker when there are more failed FCS frames coming in.

So my theory so far is, that it's not the actual number of frames that causes this (i.e. "overloading" the card when there are too many frames). I think it's that some special combination of garbage data causes the card to crash (some invalid combinations of whatever fields in the IEEE802.11 header, wrong length field that causes a read past where it shouldn't read, something like that).

This would explain that it can be reproduced quicker when there are more failed FCS frames, the probability that some frame contains "garbage the cards don't like" is higher.

However, this explanation of course doesn't line up with your results with fcs fail not enabled. Still, I feel quite confident that this does never happen with my EZ-Wifibroadcast distribution, maybe you could test it with that? This way we'd have completely the same setup, only variable left would be local circumstances like other wifi networks.

You can download it from here: https://github.com/bortek/EZ-WifiBroadcast/wiki, write it to an SDcard, edit wifibroadcast-1.txt on the boot partition (only FREQ=XXXX needs to be changed) put it in the Pi and let it run. SSH login is standard l:root p:raspberry. If you want local console access, switch over to tty10.

[melyux]

@rodizio1 Sure, I'll test it with EZ-Wifibroadcast. Do I just boot it up and put the interface in monitor mode, or do I need a second device like it says on the page?

[rodizio1]

No second device needed (as long as you don't want to transmit and receive live video), just write the image onto an SDcard and boot it up. Cards will automatically be in monitor mode on channel 13 after bootup. You can use up to three wifi sticks.

[erikarn]

Hiya,

can you turn on NFCAL debugging and see what it's doing?

-adrian

[melyux]

@erikarn How is that done?

[erikarn]

https://wireless.wiki.kernel.org/en/users/Drivers/ath9k/debug

compile ath9k/ath9k_htc with debugging, then enable the CALIBRATE bit as mentioned there, and check dmesg

it should be doing NF cal every 30 seconds or so.

It doesn't do periodic noisefloor calibration. Only when changing channels.

[melyux]

Just got the EZ-Wifibroadcast image running for one card, and on the other card enabled the calibrate bit. No messages in dmesg even with the bit set though, and the packets haven't stalled on either yet as of 5 minutes in.

[erikarn]

hiya,

ok, let's figure out how/why behind doing periodic calibrations. That sounds like a bit of a bug.

So, the EZ-Wifibroadcast image card has stalled with the fcsfail option untouched (which I assume means it's off). The card with calibrate bit enabled has not stalled yet as of 12 hours later (I expect it to stall within the next few hours as it becomes morning), and there are no messages in dmesg at all about it. Are they really supposed to be in dmesg, or maybe somewhere else?

[erikarn]

they're supposed to be in 'dmesg'. type dmesg, don't look at console output.

If it only is logged during NIC startup then yeah, let's figure out how to fix that!

I'm definitely not seeing any periodic messages in dmesg from any of the cards, but I don't think there's anything on startup either. @rodizio1 Do you know what the message is supposed to look like? It's strange because /sys/kernel/debug/ieee80211/phy1/ath9k_htc/debug does contain 0x00000008 (the CALIBRATE bit) for both cards.

[rodizio1]

Well, crap :) That makes my "bad content frames" theory invalid or we have two different issues here.

Yes, it doesn't forward fcsfail frames by default. I'll make something that allows to inject a lot of frames for testing to verify your "too much frames" theory.

This is what I get with debug=0xffffffff module parameter, NF calibration is done, but only on ifconfig up or channel change:

Note, the lines starting with "ATH:" (in uppercase) are printk's that I added myself to the source to see which function the driver calls.

That's strange, I wasn't even getting these messages when I had 0xffffffff set. I have the kernel compiled for debugging ath9k_htc and set the bit and everything.

[rodizio1]

I have these wireless related debugging settings in the kernel .config file:

CONFIG_CFG80211_DEBUGFS=y
CONFIG_MAC80211_DEBUGFS=y
CONFIG_ATH_DEBUG=y
CONFIG_ATH9K_DEBUGFS=y
CONFIG_ATH9K_HTC_DEBUGFS=y

[melyux]

Thanks, turns out I neglected to enable CONFIG_ATH_DEBUG the first time around. Now I got it recompiled, and I can also report that it's not doing any periodic calibrations. Here's the output for one of the cards when I manually switched the from channel 1 to channel 2 after it stalled on channel 1:

There are no new messages in dmesg after it starts stalling, nor when it is performing normally.

@rodizio1 Here's something to try: I wrote a script to switch through all the channels 1–11 every 10 minutes and return back to channel 1 for another 10 minutes, and found that it begins stalling a lot faster after this. It stops stalling of course when the next channel hopping session begins. My script also gets the packets seen in ifconfig and prints something out if it doesn't change within 3 seconds, so that's how I know it's stalled.

[erikarn]

the bug is that we should be doing periodic nfcal and other calibrations or the nics will slowly go deaf.

Sounds good, but why would that deafening process depend on the volume of packets (or some certain type of error packet?) as seems to be the case? Does more traffic accelerate the deafening?

Apart from the conspicuous lack of periodic calibration messages, the only things I've noticed is this message occasionally in dmesg:

[ 5743.651260] ath: phy0: Timeout waiting for WMI command: WMI_REG_RMW_CMDID
[ 5743.651314] ath: phy0: REGISTER RMW FAILED:(0x4048, -110)

and the extreme increase in the frequency of the stalling when channels are switched occasionally. If I run a script to change the channel once every 10 minutes, the cards sometimes begin to stall within minutes or seconds of being set to a channel. For this area, at least.

[olerem]

@melikyuksel , it has nothing to do with number of packages. My adapter was running for some days now, and it is still working. More noise in the air will force the adapter to increase the noise floor level on rx line. The noise is not always at same level, it can have spikes. So if adapter will apply the filter at the level of this spike, then we will get deaf. The ath9k code has logic for periodic calibration. ath9k-htc don't have it. Some one should make this code common, between ath9k and ath9k-htc.

[melyux]

@olerem Thanks for the explanation, it makes a lot of sense (although not quite sure why switching channels often triggers a very quick deafening... maybe more noise is introduced during the switching process?). Is there anything one could do to add the calibration to the -htc themselves at the moment?

[olerem]

@melikyuksel , ... "Some one should make this code common, between ath9k and ath9k-htc.", most probably i will not find time to do this. So every one is welcome to contribute ... it is open source. The patch will look probably like this: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=67dc74f15f147b9f88702de2952d2951e3e000ec

[rodizio1]

@melikyuksel Those crashes/issues you see while switching channels is a different issue. I also have these problems, something is buggy there, also happens when switching to promiscous mode sometimes.

@olerem/erikarn: How can you guys be sure that it's the missing periodic noise floor calibration that is causing the issue? Why can I reproduce this without any noise-spikes being present, just by receiving a lot of bad-FCS frames? Different issue?

[melyux]

@rodizio1 True. I ended up writing a script to check for ath9k_htc interfaces, check if they're on monitor mode, and then check the RX packages every 5 seconds. If the packets stop increasing, it just quickly switches the channel and then switches it back. This seems to have "solved" these issues, but now I'm having the issue when multiple ath9k_htc cards don't start that you were having in the other thread. That's a whole another matter in itself... It's a pity we bought so many of these cards.

[erikarn]

It looks like HTC NICs do calibration: ath9k_htc_start_ani() will start the ani work, and ath9k_htc_ani_work() will do the actual ANI, shortcal, longcal work.

The trouble(!) is, the ani_work is only added in certain circumstances, which is "technically" correct for ANI, but wrong for shortcal/longcal.

Eg - in ath9k_htc_add_interface(), it's only started if it's an AP, and ANI is enabled. For STA mode in ath9k_htc_bss_info_changed(), it's only started if it's associated, and number of associated vifs is 1.

For monitor mode, it's not doing ANI, which means its not doing periodic calibration.

So as a test, let's just enable it always for monitor mode.

diff --git a/drivers/net/wireless/ath/ath9k/htc_drv_main.c b/drivers/net/wireless/ath/ath9k/htc_drv_main.c

index a553c91..a4f84c2 100644

--- a/drivers/net/wireless/ath/ath9k/htc_drv_main.c +++ b/drivers/net/wireless/ath/ath9k/htc_drv_main.c @@ -1104,6 +1104,11 @@ static int ath9k_htc_add_interface(struct ieee80211_hw *hw, ath9k_htc_start_ani(priv); }

• if (vif->type == NL80211_IFTYPE_MONITOR) {

• }

• ath_dbg(common, CONFIG, "Attach a VIF of type: %d at idx: %d\n",
          vif->type, avp->index);

And I'll go look at tidying this code up to always run the ANI routine in hostap/STA/monitor/mesh mode so periodic calibration runs, then just skips ANI if ANI is configured as disabled. This whole "don't do ANI" stuff is conflating with the "do periodic calibration" stuff, and that's why your NICs go deaf. :-)

@erikarn I would love to try this patch on the Raspberry Pi, but I can't seem to recompile the ath9k module on there without somehow messing up its ability to handle more than 2 AR9271 devices at the same time (seen in the other issue thread). I'll try it later with a fresh install. I will be trying this on Debian however!

EDIT: Managed to get the patch applied to both Debian and Raspbian and get all the cards up, and I'm testing them right now.

[erikarn]

hiya,

please do test it out. I'll get linux-next going again on something laptop-y next week so I can fully figure out what's going on with all of this calibration nonsense. :)

@erikarn I seem to have had the first surrender, where one of the cards stopped after 50 minutes (with channel hopping being done every 10 minutes). But where is that printk message supposed to show up? I checked dmesg and did not see it there, but I modified some of the messages in hif_usb.c at the same time, and I do see those. Those use the dev_info function, apparently:

dev_info(&hif_dev->udev->dev, "ath9k_htc: MODIFIED Transferred FW: %s, size: %ld\n",
                 hif_dev->fw_name, (unsigned long) hif_dev->fw_size);

Just checking in case the patch didn't go through for some reason. I wrote a test module ("hello world!") with printk and that did show up in dmesg, so I don't think the driver's even getting to this line.

[erikarn]

It's supposed to show up when the interface is created. If it's not printing it out, then it's not starting.

Which kernel version are you using? Does ti really not show up in 'dmesg' ?

@erikarn This is 4.4.50. It doesn't show up in dmesg, but expected lines from the other files do show up. Just not this one.

[erikarn]

ok, need to figure out why that is. Can someone else help out enabling the ANI timer like I have in that patch? It should make things work.

-adrian

[rodizio1]

I have added the patch now to Raspberry Kernel 4.4.11. It seems the "if (vif->type ..." condition does not match. Commented out the if condition and then I get the "ath9k_htc_add_interface: starting ANI, monitor mode" debug line in dmesg.

[erikarn]

ok, does that fix it?

also, can you printk the vif->type value? What interface type are you creating?

@erikarn Had the chance to test it. The vif->type value prints out as 2, which, if this is where it's getting it from, means NL80211_IFTYPE_STATION instead. But it seems this part of the code only runs when the device is first plugged in (by default in station mode), and not again even when we bring the interface up or later when we put it into monitor mode.

[rodizio1]

Yes, I can confirm this. dmesg debug log only appears once after plugging the card.

Is this sufficient, i.e. will the chip still do noise floor calibration after it has been "ifconfig upped/downed" and put into monitor mode?

[erikarn]

hi,

ok, we need to figure out how to get it to start ANI whenever the interface is created as well as down/up. It should always be doing period noise calibration when the NIC is up.

Did you manage to solve this issue? I am having the same problem with COMPEX WLE350NX-7B mPCIe module (AR9580) and kernel 3.2.70. I tried all your suggestions with same results.. By now I solve this issue by detecting that the interface is stalled when I have too many select time-outs when reading the card in C code and then changing to another channel and setting it back to the one I want. It works but it is just a workaround...

[zimiao815]

thank you all，I according to your explanation，Modify the code，The original short time is deaf。Can now listen to 10 hours more。 Have the effect ！！！ According to the following debug information I should do next？？？？ thank you very mach
