[wireless] rt2870sta BUGs on shutdown, 2.6.30.2->git.today+git.wireless.today

[Mike Galbraith]

Greetings,

$subject appears (at glance) to happen because threads have already
exited when we get to BUG_ON(), I haven't pursued it though.  Using
rt3070sta instead of rt2870sta works a treat with same box/adapter.

(the 2009_0521_RT2870_Linux_STA_V2.1.2.0 tree patches and rpm'd up for
opensuse-11.1 with kernels 27->29 doesn't BUG.. for 30 onward, I'm using
the in kernel staging drivers)

Box is el-cheapo (Aldi supermarket:) Q6600
lsusb: Bus 001 Device 003: ID 13d3:3247 IMC Networks 802.11 n/g/b Wireless LAN Adapter

Other than the BUG on shutdown, the thing works fine.

Sorry, but that '/staging/' thing in there means we cannot support this.
If you must, take your query to the staging list,
devel@driverdev.osuosl.org (according to MAINTAINERS).

Forwarded, thanks.

....hm.  Does "If you must" mean reports aren't welcome?

To be honest, I don't know. I'd rather see people use the rt2x00 code
instead of spending time cleaning up that mess (the code you've pasted
was pretty bad!). But you may or may not find somebody who cares about
that, just rather unlikely on this list.

Understood (and yeah, the source is.. not pretty).  Sorry for the noise.

WRT rt2x00 with this adapter, I tried it, was a nogo.  If I find time,
I'll reconfigure/report.

What is appreciated is people with time to compare both code paths,
and report some inconsistancies, specially about card initialization
and general handling.

To be hones, we, the rt2x00 team, find Ralink's code to be very
difficult to follow, and combersome most of the times.

But any help is welcome!

This is nogo with rt2x00 driver fwiw.  Maybe some simple configuration
thing, but I'm having no luck getting the bugger to work.

rt2800pci which I would need for my Asus Eee 901 is not even ready for
the upstream inclusion (after a year or so since Ralink's driver has been
released).

The sad reality is that some vendors have discovered "the loophole" in
the current kernel development model and are using it.  Pretending that
the GPL-ed-but-fugly _working_ drivers do not exist is not an answer!

[ Especially not in the long-term (I think thank the support for the newest
  generation of Ralink chipsets will probably also be based on more-or-less
  the same code base). ]

Users are pragmatic beasts and don't care about "proper" code.  They are
just using what works "good enough" for them (i.e. if distribution ships
a slightly inferior solution to the official one nobody will bother with
the official one, now lets think about the incomplete official one..).

No, I don't have a good answer for the problem.  However I think that we
should be looking for the real, long-term solution instead of pretending
that the issue doesn't exist.

You are talking about people who:
* are familiar with wireless networking and wireless drivers
* have ability to work with the ugly/complicated code
* have good code reading/review skills
* have a quite some free time in their hands

Well, good luck..

I completely agree but it _works_, rt2x00 does _not_.

> But any help is welcome!

I think that cleaning of vendor drivers is an indirect form of help to
rt2x00 team (by making the mess easier to read and comprehend) and not a
competition to rt2x00 project.  rt2x00 code is of very high quality and
I'm impressed by the work done by you, Ivo and the rest of the team.
However I think that you will never able to out do the _vendor_ when it
comes to the support for their new devices and I find the idea of finding
highly skilled volunteers helping with the most difficult, tedious and
thankless parts of the work a bit over-optimistic.

I planned, and actually did write, a lengthy reply for this thread, when I completed the reply
I reconsidred and opted for this shorter reply. Every 2 or 3 months this discussion is started
again and I am f***ing tired of it, so excuse me but I am not going to throw myself into
this completely pointless discussion

What you are suggesting in your mail is something the rt2x00 project did for 5 years, we stopped
with that 4 months ago because it wasn't working out. Apparently you have more experience in this
matter so I hope you will find a way to make that solution work out.

If you want to maintain the legacy drivers then do it, start a new project and start maintaining
the code. I can forward you all the users with complains about the "good enough" drivers. It is
good to know that you apparently have the resources to maintain the old drivers. 
Most people who are helping with the rt2800pci/usb drivers lack the required time to boost the driver
into such a state it can be widely adopted. But every time it amazes me that the people who want
to develop and have the time to do it, all want to jump on the old Ralink code... Apparently there
is some appeal to maintaining crap rather then helping to ship out proper drivers to the users.

But I'll shut up now, as I said this discussion is held every few months, so perhaps that when
the discussion is started again in a couple of months I am more interested in a lengthy reply.

This is exactly why I was against staging all the time. Now suddenly
"The Crap" seems like a viable alternative. WAKE UP PEOPLE. The code is
not useful. Just look at the code that Mike pasted into his email. That
alone should be enough to send cold shivers down your spine!

What staging has achieved here is giving the crap vendor code a
blessing, receiving it welcomingly and forgivingly instead of saying
"well screw you, go ahead and ship this to your users but don't ever say
you support Linux well" ... now even some hackers and just just "dumb
users" think that the crap in staging could possibly at some point
become useful code!

It won't. EVER. No matter _how_ much you clean it up, it will NEVER fit
into the code scheme that everything else wireless has adopted.

And, Bartlomiej, don't give me the straw-man argument of user support,
if all you cared about were users you could well have _distros_ ship the
crap. They don't want to, of course, support this, for good reason! As
long as the vendors don't wake up, and some people see The Crap as a
viable alternative, good hardware support will never become a reality.

Look what you've done, really! You've frustrated the only person (Ivo)
who cares about giving these devices _proper_ support to a point where
he's no longer really interested in it because he's always measured
against The Crap right away. And that's perfectly understandable!
Effectively, you're saying that while he may have done good work, you
don't care about it because it's not perfect. Mike at least was willing
to try rt2x00 and work with it.

And now you're coming out of the woods and claiming that The Crap
works?! When the thread started with how it crashed? Get real.

In the end, while the letters you typed into your email claim to say the
opposite, the message of your email is that nobody should care about
rt2x00 and that the vendor driver should remain the status quo. Well, in
that case, get lost, crawl into the staging list and at least don't
bother us with The Crap.

Such attitude is part of the problem, the other big part is that vendors
can now claim their hardware "has mainline Linux support (in the staging
area)" and nobody will be the wiser.

So how about you help work on it, or think about a solution instead?

Hm, "useful" is in the eye of the beholder.

There is no driver in the mainline kernel tree for this device, so a
"normal" user has no chance of getting it working, right?  That's why
-staging is working, there is a semi-working driver, and most
importantly, people willing to help out getting it working better.

The combination of the two is what works here.

So please, I understand your frustration on a lack of people helping out
with out-of-tree wireless drivers that don't quite work properly, but
please, that has NOTHING to do with the staging drivers.

Meanwhile, I'm off on the driver-devel list helping Mike fix this
problem, which seems simple enough to solve...

Odd, I don't seem to be giving anyone such a "blessing", you are reading
way too much into this.  The fact is this vendor does code drops and
runs away all the time, despite the code being in the staging tree or
not.  Without it in the staging tree users would be worse off, not
better, there is no pressure able to be applied here at all, so please
stop thinking that.

never say never, it will happen, just give us time :)

In the meanwhile, people like Bart and others are doing real work on
getting the staging code into shape and working for real users.  Who are
you to tell them to not do such work?

Except that the energy you're now investing in fixing this could have
gone into rt2x00, and we would come out ahead in the end.  Instead, the
energy is sapped away by something that will *never* be mainlined.

On the contrary, I would have never spent any time working on rt2x00 :)

And are you trying to tell people _what_ to work on here?  That's a
slippery slope...

rt2800usb: memory corruption?

[Mike Galbraith]

Greetings,

Fiddling with my box's builtin usb wireless adapter with the rt2x00
driver in .git.today to tinker with associate problem.

snip repeat forever...

(My association problem seems to have improved markedly.  It's a little
wobbly as you can see in the dmesg output below, but does associate, and
I can ping router.  Can't use nic yet though, seems to be kinda limping
along.. shrug, progress)

Anyway, while piddling with above woes previously, I encountered a few
hard lockups while doing down/rmmod/modprobe cycles.  I encountered the
below (box survived this time obviously:) on third attempt this morning.

I suggest that you try kmemcheck.  It's very slow, but it finds memory
problems when they occur, not when it's too late.

You may want to disable kmemleak and framebuffer support and make sure
that X doesn't start, at it will be too slow.  Slub debugging might
conflict with kmemcheck, so it's better to disable it.

I didn't even get as far as down/rmmod.  Kmemcheck fired as soon as the
interface came up.

Corruption seems to be SMP only.  I cycled down/rmmod/modprobe a few
times with kmemcheck enabled (disables smp unfortunately), kmemcheck
didn't trigger, nor did box have a conniption.

P.S.  I'm no longer considering moving box away from router (and if I
ever do, I'll use repeater instead), so wireless connectivity via this
adapter is a dead issue here.  Since I have the hw though, if anyone
wants patches tested, feel free to holler, and I'll give them a spin.

This is very true, I had too many questions about the different
symbols, and task vs pid variations  etc etc....and so many macro
usage :-)....
But thank you for all the efforts of debugging!!!!

The fix is here:
http://marc.info/?t=124942266800001&r=1&w=2

kmemcheck wasn't helpful at resolving it, as the problem was with
writing after the end of allocated memory, not with reading
uninitialized memory.  SLUB debugging nailed it as soon as I took care
to understand what it was telling me.

As for the issue you found by kmemcheck, it's most certainly unrelated.
If you can reproduce it with the rt2xxx patch, consider reporting it to
the netdev list.  It would be helpful if you find what line is
triggering it and include your .config file.
