It does but I must admit that I did not test the direct probing, only the
authentication.

The problem is that when probed directly, no (real) bssid is coded in the
frame, only the multicast address. So with a frame of type
IEEE80211_STYPE_PROBE_REQ we have no chance to decode the bssid because
mac80211 doesn't give us the needed information. I think in the case of
direct probing we are lost, only the authentication works with the patch I
sent. Another solution would be to change mac80211 but that would be a
special solution for just one driver. It's questionable if this is a viable
way. On the other hand it would be great to have a working driver again.

Right. I intend to let ath_buf_set_rate() set the rates array of the
first subframe accordingly.

Sounds better to use the rate control from the last buffer in the tid
queue. But be careful if you don't memcpy it to the first frame of the
aggregate then the feedback calculated in ath_tx_rc_status() after tx
will be incorrect again, no?

* [PATCH] ath5k: fix antenna div gc for <= AR5K_SREV_PHY_2413
From: Bruno Randolf @ 2010-06-28 2:01 UTC (permalink / raw)
To: linville; +Cc: ath5k-devel, linux-wireless
In commit 39d5b2c83ca8904b6826a0713263a4e5a9c0730a "ath5k: update
AR5K_PHY_RESTART_DIV_GC values to match masks" i introduced a regression on PHY
chips older than AR5K_SREV_PHY_5413, which caused signal values to be about
10dB less that before. This patch reverts the AR5K_PHY_RESTART_DIV_GC values to
the same values which were effectively used before (without the bitmask
mistake). This brings signal levels back to normal on these PHY chips.

i guess this must be the same situation as before, no?
how many antennas do you have attached to your device? it might be interesting
to check if you get more consistent signal measurements by disabling antenna
diversity, setting it to a fixed antenna. you can do this by using a debugfs
file "echo fixed-a > /sys/kernel/debug/ath5k/phy0/antenna" (or "fixed-b")...
btw: when the signal measurement was low, did you see any negative impact on
the thruput as well?

The check for IEEE80211_STYPE_AUTH may be insufficient since direct
probe is sent with frame control IEEE80211_STYPE_PROBE_REQ. Maybe a
better check would be comparing struct ieee80211_work.type to
IEEE80211_WORK_DIRECT_PROBE or IEEE80211_WORK_AUTH? I am not sure if
that is accessible in the driver's tx function though.
With the frame_control check modified for either IEEE80211_STYPE_AUTH
or IEEE80211_STYPE_PROBE_REQ, it is still unsuccessful.
at76_work_join_bssid is called between the first and second direct
probe attempt. However, the CMD_JOIN command is not in the log.
Presumably that occurs because the BSSID pulled from the PROBE_REQ is
ff:ff:ff:ff:ff:ff which fails the is_valid_ether_addr(priv->bssid)
check in at76_work_join_bssid.

There's an easy solution which would take into account the 4ms frame
limit properly, and which could work without any memcpy() hacks:
I could just grab a pointer to the last buffer in the tid queue in the
ath_tx_sched_aggr() function, then pass it to ath_lookup_rate() via
ath_tx_form_aggr(), and also to ath_buf_set_rate(). Then I make those
functions use this last buffer as reference for the rate lookup.

You're (still) right I misread that part. But I think there is another
problem when the first subframe of an A-MPDU is not acked: if it has
not expired yet it is (as I understand it) prepended to the tid queue
for software retry and will therefore be the first subframe of the
next aggregate as well, which will then be transmitted with the same
"old" rates and counts as the previous aggregate. So the feedback from
xmit to rc works, but the control information flow from rc to xmit is
delayed.
I guess the real solution is your rewrite... But in the mean time
perhaps we can memcpy the tx_info control from the last subframe to
the first before calling ath_buf_set_rate() in ath_tx_sched_aggr()?
Could that have any side effects? It could make the aggregate size go
over the 4 ms limit I guess... How bad is that?

rt2x00 pulls every beacon. But not directly _prior_ to transmission as the
hw lacks an interrupt for that. Instead the next beacon gets pulled _after_
the beacondone interrupt (which is obviously triggered directly after the
beacon was sent). So, all TIM changes that happen during the next beacon
interval won't be included in the next beacon. Hence, rt2x00 also implements
the set_tim callback and updates the beacon through these as well.
This gives us a correct TIM but as I explained earlier breaks the DTIM
count (and thus bc/mc buffering which is done in mac80211 fot rt2x00).
One possible option to fix this in rt2x00 would be to delay the beacon
update (as it is already put on a workqueue we could simply replace it by
a delayed work) by beaconinterval - 10ms or something. But I'm not how
accurate that would be (and of course remove the set_tim callback).
Ivo, would that be an option you would agree on? On rt2800 we would simply
use the pretbtt interrupt and on older hardware trigger the beacon update
from a delayed work, and remove the set_tim callback?

Yes, that's what I tried to understand when I wrote the first mail as I didn't
know enough about that part in mac80211.
> Does your device fill the DTIM count field or does it not? That's really
> the only thing you need to know, no?
The rt2x00 devices don't do any semantic changes to the beacon (only update
the timestamp). So basically the approach to update the beacon once during
each beacon interval would be the nicest solution. But due to the lack of a
suitable interrupt (on devices older then rt2800) rt2x00 does it as explained
above.

With the new patch it looks like this, happens within a few minutes (3?)
of a high speed sustained transfer. (trimmed a little because I didn't
have that much scrollback). Again, still have plenty of RAM.

Well, yes, but I don't get it. Are you trying to conjure a third way of
doing things? How would you like it to work?
I don't understand why you expect to have a correct DTIM count field
when you don't pull every beacon from mac80211. If you pull each beacon
it's all correct. If you don't, you need to take care of everything DTIM
related, there's simply no way to do it differently.
Does your device fill the DTIM count field or does it not? That's really
the only thing you need to know, no?

Do you know the reason code for that? I think the check here should be

Thank you for explanation.
The patch surely improves signal strength measurement and I recomend it.
Anyway, when you look at the magenta line here:
http://78.108.103.11:11080/cgi-bin/rodga_1day_big.cgi
There are big drops in measured signal. Did you fix all places?
Before this patch there were short peeks from -78dB to -71dB.
After patch there are short measurement drops from -62dB to -70dB.
The week charting simply averages it:

no it just fixes a regression i have introduced in an earlier change. thanks

It looks, that your patch really returns back proper signal values.
I will not poison Email with png files, feel free to look at here:
http://78.108.103.11:11080/cgi-bin/rodga_1day_big.cgi
Magenta line returned back to green line from other direction.
Even in an AP mode the magenta line also jumped to expected value:

That matches otherwise with the latest draft (P802.11s/D6.0), but it
lacks one field. There is a 1-octet field "Mesh Peering Protocol
Identifier" between the _auth and _form fields in the latest draft.
