ath10k: firmware crash after setting promiscous mode

ath10k: firmware crash after setting promiscous mode

["Jose Núñez-Martínez (CTTC)"]

Hi all,
I'm trying to use an ath10k in IBSS mode with 2 wireless cards based on 
qca988x . I'd like to be able to put the wireless cards in promiscuous 
mode (ifconfig wlanX promisc). When I put the wireless cards in 
promiscuous mode, the firmware crashes. Has anyone tried this?

Kernel is 4.1 and  firmware is 999.999.0.636. Please find below the 
ath10k crash info:

That's weird. I believe promisc flag is no longer propagated by
mac80211 to its drivers (e.g. ath10k).

[...]

If you look through the list you'll find similar reports with the same
register dump values.

Firmware 999.999.0.636 has broken monitor vdev support in firmware and
often crashes when one tries to use it (which is implied by promisc
mode in older kernels or a running monitor vif).

You might be interested in using CT firmware branch[1]. Ben has added
IBSS support recently and since it's 10.1 based it has a working
monitor vdev support.

Make sure you get the beta build for best IBSS support:

Re: ath10k: firmware crash after setting promiscous mode

[José Núñez]

Solved the firmware crash issue by using latest ath10k development release from backports (I was using latest stable backports release) and kept 636 firmware. 

Promisc flag is not propagated in this version since it contains patch df1404650ccb ("mac80211: remove support for IFF_PROMISC").

Firmware crashes after setting iface in promiscuous mode no longer happening neither in IBSS nor AP mode.

Thanks a lot for your help!
Jose
