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

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 ___ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k

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

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.

ath10k firmware crashes in mesh mode on QCA9880

When we try to transmit traffic (ping) between two meshed ath10k devices running latest lede we keep experiencing ath10k firmware crashes. This seems to only happen when running in 802.11n/ac mode but not in 802.11a/g mode. Also, from the station dumps it appears that management traffic is
