Re: ath10k firmware crashes in mesh mode on QCA9880

Hi! ok, thanks! I've seen some .. annoying rate control related firmware crashes if you aren't using 11ac / 11n rates (ie you're /really/ legacy, so I wondered if something similar is going on here. Thanks! -a On 13 December 2016 at 22:06, Alexis Green wrote: > Hi

Re: ath10k firmware crashes in mesh mode on QCA9880

Hi Adrian, I have not done much testing of ath10k and ath9k devices in a single encrypted mesh recently, but I have a memory of only having this issue when communicating between ath10k devices. Alexis On Tue, Dec 13, 2016 at 9:53 PM, Adrian Chadd wrote: > Hi! > > Hm! So is

Re: ath10k firmware crashes in mesh mode on QCA9880

Hi! Hm! So is there a firmware bug if there are 11n only capable nodes in an 11s mesh? -adrian

Re: ath10k firmware crashes in mesh mode on QCA9880

Thank you for your help Rajkumar, We've traced the problem down to a peering issue. Looks like there was a missing compile flag that caused some kind of incongruence. My best guest is that beacons are generated by firmware and advertise support for AC mode, whereas wpa_supplicant, when not

Re: ath10k firmware crashes in mesh mode on QCA9880

Tested the 10.2.4.70.59-2 firmware and wpa_supplicant running WITHOUT encryption and it still crashes. I suspect this means wpa_supplicant is setting up the interface incorrectly and/or transmitting a malformed packet that is causing the driver to crash. [ 162.010206] ath10k_pci

Just tested the latest 10.2.4.70.59-2 firmware and it still crashes with wpa_supplicant encrypted mesh =( [ 85.201440] ath10k_pci :01:00.0: firmware crashed! (uuid b7f44483-0488-46af-8dff-db88f4b56327) [ 85.210573] ath10k_pci :01:00.0: qca988x hw2.0 target 0x4100016c chip_id

Re: ath10k firmware crashes in mesh mode on QCA9880

1. Yes, this appears to happens every time a unicast packet with wpa_supplicant encryption in VHT80 mode is received. I haven't seen a successful ping-pong pair. 2. We tried with 10.2.4.70.42-2 firmware and still saw crashes. 3. We ran our experiment again with extra debugging turned on.
