AR9271 random freezes in Ad-hoc mode when distant client disconnect #145

Open dagf2101 opened 6 years ago

dagf2101 commented 6 years ago

This is similar than issue #137 but since it is Ad-hoc related and the problem happen when a remote client disconnect(instead of connect), I have decided to repost it in its own thread.

I'm also providing new logs with all ath debugs enabled.

Issue: On AWUS036NHA in Ad-Hoc mode on kernel 4.15 / 4.16. We are using a network of around 8 devices connected to NUC PCs in our tests. Every time a device disconnect, other devices have a chance to crash. I reproduce it by rebooting one of the PC and eventually other devices start crashing the kernel thread freeze on those crashed nodes.

First the log show a working sta entry remove, and then later it show one that crashed the card.

Here is the kernel log: 7,9361,911527345,-;ath: phy2: Choose slot: 0, tsf: 528240644, tsftu: 515860, intval: 100 7,9362,911629831,-;ath: phy2: Choose slot: 0, tsf: 528343045, tsftu: 515960, intval: 100 7,9363,911732122,-;ath: phy2: Choose slot: 0, tsf: 528445445, tsftu: 516060, intval: 100 7,9364,911744161,-;ath: phy2: Set HW Key 4,9365,911745132,-;FDB: ath9k_htc_sta_remove before cancel_work_sync 4,9366,911745139,-;FDB: ath9k_htc_sta_remove after cancel_work_sync 7,9367,911745618,-;ath: phy2: Removed a station entry for: 00:c0:ca:97:3a:cc (idx: 4) 7,9368,911834579,-;ath: phy2: Choose slot: 0, tsf: 528547842, tsftu: 516160, intval: 100 7,9369,911936951,-;ath: phy2: Choose slot: 0, tsf: 528650245, tsftu: 516260, intval: 100 7,9370,912039331,-;ath: phy2: Choose slot: 0, tsf: 528752643, tsftu: 516360, intval: 100

Hi, i know there is some thing fishy with ad-hoc mode. For some time I made this script to crash the system just by spoofing ad-hock interface: https://pastebin.com/KhXgQ15V But i really don't have time to do it now. If you can investigate it, it will be really good.

dagf2101 commented 6 years ago

Just tried your script, looks like I can use it to reproduce our bug. Instead of connecting to the adhoc using iw dev ibss I am using the wpa_supplicant with the following configuration: https://pastebin.com/hpLJ0LBW

Simply ifconfig down; macchanger; ifconfig up can trigger the same bug.

Do you think it is a firmware or driver related problem ?

erikarn commented 6 years ago

Hi,

This is a driver bug, not a firmware bug? It's hung inside the driver.

This is similar than issue #137 https://github.com/qca/open-ath9k-htc-firmware/issues/137 but since it is Ad-hoc related and the problem happen when a remote client disconnect(instead of connect), I have decided to repost it in its own thread.

I'm also providing new logs with all ath debugs enabled.

Issue: On AWUS036NHA in Ad-Hoc mode on kernel 4.15 / 4.16. We are using a network of around 8 devices connected to NUC PCs in our tests. Every time a device disconnect, other devices have a chance to crash. I reproduce it by rebooting one of the PC and eventually other devices start crashing the kernel thread freeze on those crashed nodes.

First the log show a working sta entry remove, and then later it show one that crashed the card.

I thought it was freezing because the card was dead and not responding anymore. I will try to get a cable to connect to the UART and log the firmware output...

Anything else I can try or enable in the kernel that could help ?

erikarn commented 6 years ago

Hi,

Well if the firmware is freezing then ideally ath9k-htc would also handle that case without it crashing.

My last research on this topic was in 20 Oct 2014: https://www.spinics.net/lists/linux-wireless/msg128248.html may be it can help you.

dagf2101 commented 6 years ago

Thanks @olerem for this information.

It looks like I would need to increase the max station support into the firmware. (probably from 8 to something around 16)

The Idea proposed here is to remove some station information from the firmware and keep it in the kernel driver instead.

I am pretty lost looking at the firmware code, can someone point me where to start looking or where this hard limit is enforced in the firmware ?

Or if you guys have a idea where we can easily save resources.

olerem commented 6 years ago

@dagf2101 , on you place I would attach UART and add some prints in to the firmware. If will allow you to see how it works. Suddenly we have no available open source solution to JTAG this chip.

dagf2101 commented 6 years ago

Yeah I will do but still haven't received the cable... damn bureaucracy.

olerem commented 6 years ago

I thought each SW/HW developer has a bucket full of cheap uart adapters...

dagf2101 commented 6 years ago

Looks like the bucket is empty here.

dagf2101 commented 6 years ago

Ok I received this cable from digikey but cant make it work. Soldered the rx, tx and ground as shown here: https://photos.app.goo.gl/PVC8acPcVmnzPTnq8 (I also tried to invert rx and tx)

Trying to connect to the USB serial device (19200) but I dont see anything... I'm also getting weird driver errors into ieee80211_ibss_rx_queued_mgmt.

Maybe I have the wrong cable or I'm missing something ?

olerem commented 6 years ago

I already had one issue with exact this cable. Purchased 3v3 version and got 5V version. Check this with scope or logic analyzer if you have. If not, make sure the WiFi is still working after desoldering of this cable.
