Hi,

Firstly, please cc me into any any replies - I'm not subscribed.

In 2.6.25 kernels, my wireless LAN dies after even the smallest amount
of network activity. The following screen cut shows what I typically
see:

As you can see, after a few packets, the ping application hangs and
after that point, all network accesses fail. There are no error
messages written to the logs when the network dies. I can restart the
network by simply unloading and reloading the driver. This hang does
not occur with a different wireless card that uses the rtl8180 driver.

My config and the output from dmesg (after reloading the driver) are
attached. I have Ralink debugfs enabled so can provide any additional
diagnostics that may be helpful from that source.

(I should perhaps add that I am sure that this is not the same problem
I reported tthrough bugzilla (bug 9860) a few weeks ago, which it
seems was a problem with my AP/router. Since resetting my AP/Router, I
can reboot to 2.6.24.2 and the wireless network works reliably with
the same hardware.)

The hardware is a Belkin F5D7010 802.11g Notebook card communicating
with a Draytek Vigor 2600 802.11b combined AP/Router/Broadband Modem.

I will be more than happy to provide additional diagnostics, but
please bear in mind that I am not a git user, so cannot do bisects. I
am, however, perfectly capable of applying or reverting patches,
rebuilding and re-testing, so I am quite happy to do that.

Thanks in advance.

Chris

Hi,

How complete is this failure? Just TX or also RX?

Could you use the tools found here:
http://www-user.rhrk.uni-kl.de/~nissler/rt2x00/index.html

and capture all TX/RX frames going through the hardware?
Note that after the failure, this dumping facitilty should still report
any ping request you might send to the interface.

I have a series of tests I would like to request from you,
you mentioned you already enabled debugfs, and that is just what we need. ;)
Please use attached script to create dumps of the hardware register contents.

There are specific moments that should be dumped:
- kernel 2.6.24 (last known working version for you).
- kernel 2.6.25-rc2 (after ifup, before TX dies)
- kernel 2.6.25-rc2 (after ifup, after TX dies)

Above traces should be enough, but to determine where rt2x00 broke
down approximatly I need to have a few test result on specific moments.
Could you test the kernel with the following versions:

rt2x00 2.0.11	2d68de3efa62655d551092f5c787505735d561ad
rt2x00 2.0.12	a3c7aa58df7df80aa05f166fe3e42482247164cf
rt2x00 2.0.13	5a6012e105ae1664cd2841c33bf59fbdd8d4dbcc

Checking those out is simply a matter of:
git branch 2.0.11 2d68de3efa62655d551092f5c787505735d561ad
git checkout 2.0.11

No further bisecting is needed, but with above tests I can at least
narrow it down to find the cause of this issue.

Thanks.

Ivo

Note that this feature is only present in 2.6.25.

The debugfs register files were moved into a seperate folder somewhere between
2.6.24 and 2.6.25. This means you might have to edit the file slightly to make it
point to the correct location of the chipset file.

It will be tomorrow before I can provide this because I'm struggling to get
wireshark to build against the old (2.4.x) kernel headers that match glibc on
my laptop. I'll build it on my desktop, which has more recent headers, and
decode the frame dump there. But I need sleep now :)

Could you use below patch instead, and make a new dump of the register?
I'm still convinced the breakage occurs in the antenna diversity (or rather, I believe
it attempts a software diversity for your card while in fact it shouldn't).

Thanks, I think I miss some information in that dump,
but that is okay for now.

Sorry, I've applied that patch and the LAN still dies after a few pings. BTW,
this and the earlier patch both apply without error, but give warnings of 70
line offsets. Were you expecting them to apply completely cleanly? I'm just
wondering if there might be some code that you are expecting to be running (or
not running) that is (or is not) present in the driver at 2.6.25-rc2.

The register dumps before and after are attached.

Thanks,

Chris

Well to be honest I based the patch on rt2x00.git and not 2.6.25-rc2.
I know the patch would apply safely because the function that were changed
in that patch haven't changed between them. But some other functions were
moved. So that offset is correct. ;)

Thanks. I hope to have a new patch ready soon.

rt2x00 2.0.14 is broken with my rt73 stick in the vanilla 2.6.25-rc2
kernel (not wireless-2.6/rt2x00 git).  The modules load when I plug the
stick in but I then get a complete kernel lock up with two flashing
leds.  Nothing is recorded to system logs.  The last logged messages are
that usbcore has registered new interface driver rt73usb, and that the
rate control algorithm has been selected on phy0.  This happens whether
the simple or pid mac80211 rate control algorithms have been chosen.

This is a shame because 2.0.14 was working really well for me until the
mac80211 changes 2 or 3 weeks ago broke it.  (Shortly followed by the
release of 2.1.*).

Switch to a VT with Ctl+Alt+1, then plug the stick in, and take a
picture of the panic if one shows up.  _Something_ should show up on the
VT.

I did that yesterday and it just reported a kernel panic on the terminal
with the message:

  Kernel panic - not syncing: Aiee, killing interrupt handler!

There is a complete lock up.  Even the two leds don't send a dump in
morse code (if that is still a feature of the 2.6 kernels).  They just
flash together at 1 second intervals.

However, I do not have debugging enabled on 2.6.25-rc2 (I was just
interested to see how it worked).  If it is thought to be useful I can
recompile the kernel with debugging enabled, but this should be
reproducible by anyone with a rt73 stick.

By way of a further data point, I can scan OK using 2.6.25-rc2 and it
will report all the available access points in my area.  But as soon as
association is attempted, it blows up.

I have an idea, could you try below patch?
Note that while applying it will mention something about a line offset, but that can be ignored.

This could perhaps also fix the TX/RX issue mentioned earlier in the thread, but I am not
quite sure about that.

Here's some further information.

I have a fully functioning version of rt2x00-2.0.14 and mac80211 from
wireless-2.6/compat-wireless-2.6 of mid January which works fine on
kernel 2.6.24.  On doing a comparison with the rt2x00 in vanilla kernel
2.6.25-rc2, there are no material differences.  (There was a slight
change in the declaration a variable in rt2x00usb.c but it is
immaterial.)

I compiled up the working mid-January version of rt2x00 and mac80211
under kernel 2.6.25-rc2 and I get exactly the same result as I reported
earlier, namely I get a kernel panic as soon as I try to associate.  It
looks therefore as if something has changed within the remainder of the
kernel which has caused rt2x00 (and possibly mac80211?) to break.

This probably explains the problem another user reported with rt61.

Chris

Perhaps something similar like:
http://bugzilla.kernel.org/show_bug.cgi?id=10058
in there a reference is made to the following patch:
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.25-rc2/2.6.25-rc2-mm1/broken-out/revert-send-a-single-notification-on-device-state-changes.patch

Does applying that help?

Yes, well done.

I have spent 20 minutes testing it and it seems to work fine (at least
as well as 2.0.14 does under kernel 2.6.24).  The rate control algorithm
seems to work better as well, but that is probably a mac80211 thing.

Excellent, I am currently updating rt2x00.git from wireless-testing to get
the above mentioned patch into the repository.

I'm afraid not, Ivo. The test I ran last night was against 2.6.25.-rc2-git4 and
that already has this patch applied. Furthermore, I have another card that uses
the rtl8180 driver and that works reliably. I, therefore, suspect that my problem
lies within the rt61pci driver or the rt2x00 infrastructure.

Does the same happen with 2.0.14 under kernel 2.6.24?

Unfortunately, a 2.6.24.2 tree with the drivers/net/wireless/rt2x00 directory replaced with that from 2.6.25-rc2-git4 doesn't build:

OK, we seem to be struggling a little, so I've built an installed git
and cloned Linus' 2.6 tree. My wireless network dies after a few pings
with rt2x00 2.0.11.

If you need me to bisect, just shout. Please be patient though, I'm

You need the mac80211 compat  module from Intel. That allows new mac80211 versions to run
on older kernels. When you use that you need to grab the rt2x00 cvs tarball from:
http://rt2x00.serialmonkey.com/wiki/index.php/Downloads

which allows rt2x00 to be compiled outside of the kernel.

I don't think bisecting this will help a lot, the rt2x00 2.0.11 release
introduced software diversity. And that is already something I suspect
of being broken.

Unfortunately software diversity was a bugfix and fix in one,
the previous setup was broken for some hardware since the
lack of software diversity caused problems.

Could you check if below patch helps in any way?

You have to have a version of mac80211 which is current with the version
of rt2x00 2.0.14.  If you don't want to go back into wireless-2.6 git to
do that I can send you my known working copy (for rt73 and I hope for
rt61) of compat-wireless-2.6 which will compile under 2.6.24.  However
it is just over 1MB in size so I won't sent it to you unless you would
like me to do that instead of you pulling git from wireless-2.6 for mid
January (actually the most recent working version would be immediately
before the patch which raised the version of rt2x00 to 2.1.0).

Hi,

Firstly apologies for trimming linux-kernel and linux-wireless from my reply 
to Ivo yesterday. Basically, I replied saying that the patch below didn't fix 
the problem. But please do read on...

 I've bisected anyway and although the results are not absolutely conclusive, 
as I neared the end of the process, I was amongst a bunch of mac80211 
patches. This set me on a path that resulted in me discovering that with the 
rt61pci driver, I can freeze my wireless network connection almost at will if 
I set mac82011's ieee80211_default_rc_algo parameter to 'pid'. if the 
parametre is set to 'simple', the network seems to be reliable. I've just let 
the ping application run on and ping another box on my network almost 1500 
times whilst repeatedly transferring a kernel source tarball by ftp from 
another box and the network connection was mantained That's with the 
parameter set to 'simple', if \I set it to 'pid' the connection rarely 
survives more than 40 pings even without the ftp activity.

If I replace my wireless card with one that uses the rtl8180 driver, the 
network connection seems to be reliable regardless of how I set the 
parameter, although I admit that i have not tested this extensively yet. I'll 
do that now and report later.

Hope this helps.

I'm about to send 4 patches to this (linux-wireless) list with patches
for rt2x00,
most of them you already tested individually, but several people reported
success after those patches.

Hopefully it will be working for you as well. :)

I've rerun my tests with the rtl8180 driver and found the network to be 
reliable with the mac82011 module's ieee80211_default_rc_algo parameter set 
to either 'simple' or 'pid'.

Sorry, but that's not the case. I find the same results as without the 
patches. With the parameter set to 'pid', the network connection fails very 
quickly, but with it set to 'simple' I can ping and ftp files to and from my 
laptop as much as I like and the connection stays up. In fact, if anything 
the patches seem to have made the network even more fragile, in that it fails 
almost instantly once I start some network activity ( < 10 pings).

I'm sure this is not the hardware - it works perfectly with Windows XP, with 
2.6.23.14 plus the out-of-tree rt61 driver from serialmonkey, with the 
in-tree driver from 2.6.24.x and with 2.6.25-rc3 with the mac82011's 
ieee80211_default_rc_algo parameter set to 'simple'.

Like I say above, sorry!

Chris

At last!  Vindication for insisting that we keep 'simple' around!
Bwahahaha! :-)

So, am I to understand that 'pid' works find for you with rtl8180?
If so, then I wonder if Stefano and Ivo can help us figure-out
what kind of problem is sensitive to both driver _and_ rate control
algorithm?

Thanks,

rt2x00 is known to be less sensitive then the legacy drivers, scanning
produces less and more inconsistent results (Not all AP's are reported,
even when that AP has a high rssi), and the reported RSSI is often
much lower then expected with the distance to the AP.
I have compared many register dumps, but have never managed to
find a real register setting that might cause this. So what might be
the problem is that rt2x00 is not reporting the RSSI correctly to mac80211.

With the big difference between how mac80211 handles TX rates and
how the legacy drivers handle them, it is hard to make a comparison
where exactly things are going wrong. But in the end, I think it all
comes down to rt2x00 reporting invalid RSSI values to mac80211,
and/or the rate control mechanism being too dependent on some
statistics which are not provided by the driver.

I have to admit that I haven't looked into the 'pid' algorithm closely,
but could it be that some fields in the tx status report upon txdone
are being treated as "very important" while the driver doesn't report it
(For example ack signal strength)?

Other then that I have to say that rt2x00 never has reached a particular
state where link quality issues can be traced back to mac80211 or
the rate control mechanism. It usually was caused by a bug in the driver
itself. (rt2x00 cannot be considered stable yet for a very good reason. ;) )

It's nice to be able to make someone happy :-)

>  So, am I to understand that 'pid' works find for you with rtl8180?

Yes John, using the rtl8180 driver I get reliable network performance
with either 'pid' or 'simple'. With the rt61pci driver, I find that
'simple' provides a reliable network, but 'pid' simply does not work.
So keeping 'simple' around gets my vote too.

And I will help in any way I can, providing diagnostics and trying patches.

No, we don't care at all about RSSI in rc80211-pid.

The only important thing drivers should report back to mac80211 are ACKed
frames. In rc80211-pid (and it's just the same in rc80211-simple) the only
inputs from mac80211 are succesfully (re)transmitted frames and failed
frames.

Here's a dump that I started, then began pinging my gateway in another
terminal until the network failed and then stopped the dump with ^C a
few seconds later. Hope it helps.

And it currently isn't queued for 2.6.25 at all.

Chris, can you cherry-pick this from the wireless-2.6.26 tree and
give it a test on your 2.6.25-rc3 tree?  If it resolves a problem
then I'll queue it to Dave for 2.6.25 (which will probably provoke
a net-2.6.26 and wireless-2.6.26 rebase).

Let me know...

That might be easier said than done.  It looks like that patch depends
on the big cfg80211 API change queued for 2.6.26.

Stefano offered to rebase that on 2.6.25.  Stefano, could you post
that as part of this thread?

Yes, that's correct. The patch doesn't apply cleanly to -rc3 and,
having inspected at it, it looks too complicated for me to hack in.

Sorry for the delay. This is based on 2.6.25-rc3. Please test.

Merge rate_control_pid_shift_adjust() to rate_control_pid_adjust_rate()
in order to make the learning algorithm aware of constraints on rates. Also
add some comments and rename variables.

This fixes a bug which prevented 802.11b/g non-AP STAs from working with
802.11b only AP STAs.

I've tested this with the pid algorithm selected and my wireless
network connection is reliable. In a loop, I repeatedly ftp'd a kernel
source tarball from another box on my network for 40 minutes with no
failure, whilst at the same time, pinging my gateway. Without the
patch, that activity would have led to network failure in seconds. The
tests were with the patch applied to 2.6.25-rc3-git3, so that Ivo's
rt2x00 patches for 2.6.25 are also applied.

Thanks to everyone who has helped fix this.
