Actually. Moved to the pending branch - shouldn't we have some feature
flags here to indicate that the driver actually supports this?

Applied. I removed that "(u8)" there, and also removed the pointless
hweight8/hweight16 - only the first one with >1 is needed.
I'd like to see a driver supporting this upstream, hint hint. :)

* brcmf_txfinalize misses 802.1x packet leading to infinite WARNINGs
From: Rafał Miłecki @ 2016-09-15 8:11 UTC (permalink / raw)
To: Hante Meuleman, Arend van Spriel, brcm80211-dev-list

Hi,
Yesterday I explained on OpenWrt forum [0] that there are 2 problems
leading to WARNINGs triggered by brcmf_netdev_wait_pend8021x.
The first one is firmware problem with A-MPDU implementation. I already
reported this in "AMPDU stalls with brcmfmac4366b-pcie.bin triggering
WARNINGs" e-mail thread [1].
Another one (I'm reporting right now) is related to brcmfmac and its
counting of 802.1x packets. The idea is simple:
1) In ndo_start_xmit callback there is check for ETH_P_PAE and code
increasing 802.1x counter by 1.
2) In brcmf_txfinalize there is check for ETH_P_PAE and code decreasing
802.1x counter by 1.
This is needed as some operations have to be handled without any 802.1x
packet pending.
Thanks to my debugging code (you can find it at the end) I just noticed
that:
1) Sometimes (very rarely) brcmf_txfinalize doesn't detect 802.1x packet
2) brcmu_pkt_buf_free_skb gets called and skb gets freed
3) Counter remains not-decreased and brcmf_netdev_wait_pend8021x will
always time out.
I'm not sure why this could be happening. The check for ETH_P_PAE looks
exactly the same in both places. My only idea so far is firmware
corrupting skb data. This fools brcmfmac code and my debugging code was
lucky enough to keep tracing skbs (by their addresses) to notice that.
I'm going to extend my debugging patch by making a copy of eth header
and comparing it with corrupted one. As this bug occurs very rarely it
make take days or weeks to get any update.
I'd love to hear any comment meanwhile.

* [PATCH] mac80211: reject TSPEC TIDs (TSIDs) for aggregation
From: Johannes Berg @ 2016-09-15 8:09 UTC (permalink / raw)
To: linux-wireless; +Cc: Johannes Berg
From: Johannes Berg <johannes.berg@intel.com>
Since mac80211 doesn't currently support TSIDs 8-15 which can
only be used after QoS TSPEC negotiation (and not even after
WMM negotiation), reject attempts to set up aggregation
sessions for them, which might confuse drivers. In mac80211
we do correctly handle that, but the TSIDs should never get
used anyway, and drivers might not be able to handle it.

Sorry to revive such an old thread..but I'm back poking at this.
I've used the modified carl9170 firmware to generate pulses, with
the control being 'pulse-width' and 'pulse-interval'.
This sort of works, and sometimes our ath10k in an isolation chamber reports
a radar event.
But, after some reading, I am thinking I need more control to better mimic
a radar.
If I understand things properly, I need something like this:
A pulse event being: pulse width, pulse period: For instance 1us, 200us
Then, I need to configure an amount of pulse events, maybe 10-30 consecutive pulse events.
Then, I need a quiet period to mimic the radar sweeping full circle (15 seconds perhaps)
From what I can tell, the carl9170 modified firmware is missing the features
to do this, though it should not be too difficult to add.
If someone has an idea whether the control above is appropriate, I'd
appreciate feedback before I start hacking...
This document seemed useful, for instance:

Hi Rafal,
Surprised to see those ampdu_dbg messages in official firmware release.
It would be great to have a timestamp for these skb when they arrive in
brcmfmac or transferred to firmware (or both).
The obvious solution would be to increase the pend8021x timeout in
brcmfmac. Probably another solution would be to exclude EAPOL frames
from A-MPDU in firmware. That still does not solve the A-MPDU stall.
Regards,
Arend

Like discussed earlier, the firmware names are supposed to be stable. I
consider them to be an interface between kernel and user space. Instead
of changing the driver you should actually rename the firmware file. I'm
planning to take this anyway but in the future please pay extra
attention to do this properly.
My recommendation is to keep the firmware name simple as possible and
get rid of any extra cruft, for example in this case a good name would
be "mrvl/usb8997.bin". That extra "usb" and "combo_v4" don't bring any
benefit.

* [PATCH] ath10k: Fix spinlock use in coverage class hack

ath10k_hw_qca988x_set_coverage_class needs to hold both conf_mutex and
the data_lock spin lock for parts of the function. However, data_lock
is only needed while storing the coverage_class to store the value that
the card is configured to.
Fix the locking issue by only holding data_lock for the required duration.

And yes, I fully agree with your points of it being rather fragile. But as
you said, it should be entirely safe if not used. Obviously a firmware
implementation would be preferential.
This locking issue was pretty unnecessary. Lets see if any more issues show
up in a closer review.

Ok, but it is still nice to have the printout info of what log levels
means. Otherwise, you have to go look at firmware source to even know how
to enable the proper flags. And as these flags are internal and might change,
we could change the printout text to match the specific kernel that is running.
In my opinion, this is a 'nice-to-have', not required, if sysfs works,
so I will also test the sysfs suggestion above.

No argument there. If you want to add a feature flag I can start setting it in
my firmware.
But, the if-combinations crap is a bigger problem than that anyway. I have
some later patches to re-work it to make it dynamically created instead of static,
but that is a fairly big change and I figured I had a better chance of getting
smaller changes upstream first.
Thanks,
Ben

One potential use for this flag: Bug reports could be automatically directed to me instead
of QCA.
I have actually re-written much of my earlier logic so that it uses specific
feature flags now. I still like the idea of having the driver (and user)
know it is using CT firmware, but I can live without this flag if needed.
Even if I change generation of my new firmware, all of my older firmware
will have this flag set though, so I would still prefer the flag exist
in the driver, even if it is not used for any serious decisions.
Thanks,
Ben

There are lots of reasons that interfaces can fail to come up or exist.
The work-around for the power-up fail is a system reboot, so I wanted to
know for certain when this case existed so that I could warn users
that they needed a reboot.
That said, I haven't seen this problem in a while, so maybe this patch is
no longer to useful.

Ben
