This bug is extremely difficult to pin down. I cannot reproduce it at
will. The system has to be up for a long time, which is difficult with
testing the late RC's of 2.6.30 and the code in wireless-testing so
that new bugs don't end up in 2.6.31-RCX. That said, it still was in
2.6.30-RC6 and I'm not aware of any changes since that would fix it.

My operating kernel is patched with additional diagnostics to help me
understand why a kmalloc request for a buffer of 1390 bytes suddenly
ends up as an O(1) request. Unfortunately, I don't have any answers.

Looks like a cpufreq locking problem to me. Lets add some
get_maintainer.pl loving to the cc list. Can you post your .config
too, btw?

Looking at the out-of-memory trace, there's still memory available but
the pskb_expand_head() allocation is GFP_ATOMIC so there's not much
the page allocator can do here. The amount of memory consumed by
inactive_file is pretty high so maybe the problem is related to the
recent mm/vmscan.c changes. Lets copy some more mm developers and see
if they can help out.

That is a very strange trace.  The Mem-Info indicates
that the system has more than enough memory free, and
also enough memory in higher-order free blocks.

This would indicate a bug somewhere in the page
allocator - this memory should have been given to this
allocation request.

I verified that the bug is still there in mainline from this morning.

The fix is part of this pull request:
	http://lkml.org/lkml/2009/6/6/148
so hopefully it will make it in before the final release.

Since i disabled most of the debug options this problem has gone. IMHO
this issue has been caused by kdbg.

I'm happy to see some action on this problem. As usual, I'm happy to

It should still be listed. I do believe I've finally identified the

Now in mainline as commit f79b1b146b52765ee38bfb91bb14eb850fa98017

I tested that current git does indeed fix the problem - my DVD writer is 
now detected and functional through the JMicron controller.

The bug can be closed.

This problem is fixed by the following patches.

f06dd16a03f6f7f72fab4db03be36e28c28c6fd6 : IMA: Handle dentry_open failures
1a62e958fa4aaeeb752311b4f5e16b2a86737b23 : IMA: open all files O_LARGEFILE

I can't really say this is a regression. I never had compiled a kernel with
CONFIG_IMA until 2.6.30-rc8. 


Thanks

I just pulled the 2.6.30-rc8 kernel.

I'm giving it a test during this week and let you know if the bug

One question. 

Did your system fragmented in same way as to this
(see DMA32, 10052 of order-0 pages) in older kernel ? I think you can check
fragmentation status via /proc/buddyinfo.
=
kernel: Node 0 DMA: 3*4kB 3*8kB 5*16kB 2*32kB 4*64kB 1*128kB 2*256kB 0*512kB
1*1024kB 0*2048kB 0*4096kB = 2100kB
kernel: Node 0 DMA32: 10062*4kB 1*8kB 1*16kB 0*32kB 1*64kB 1*128kB 0*256kB
1*512kB 0*1024kB 0*2048kB 0*4096kB = 40976kB

Nothing like a party on Monday morning to get the week started!

What we appear to have is

o Allocation failure is high-order, high-priority, compound and atomic.
o swap is mostly unused, but we cannot enter direct reclaim.
o ZONE_DMA32 can be used
o The allocation path is in the slub allocator
o Are way above the order-0 watermarks so kswapd is probably not awake
o The minimum watermark for an order-0 page was about 647 pages in ZONE_DMA32
o The minimum watermark for an order-1 page was about 323 pages in ZONE_DMA32
o There are 10244 pages free at the time of the failure
o With the order-0 pages taken out for watermark calculation, there are
  182 free pages which is below the watermark of 323 pages for an
  order-1 allocation

While there is enough free memory overall, the zone watermark calculation
takes into account the order of the request. As this is an order-1 allocation,
the free order-0 pages are taken out of consideration and so the allocation
fails.

We've encountered this before and the conclusion was that the current
adjustments for watermark calculations of high-order allocations is right,
or at least there is no better alternative. In other words, the page
allocator in this instance is behaving as expected. Do we want to
revisit that discussion as to whether the watermark calculations for
high-order allocation should change? I think we'll reach the same
conclusion or at least decide that allowing the order-1 atomic
allocation to succeed here would just postpone the problem.

So the question is why are we doing a high-order atomic allocation in
this path? According to an earlier discussion on this problemn

So, SLUB is deciding to use order-1 pages for the slab allocation.
Ordinarily, it'll get away with that because order-1 pages will be
allocated from a path that can direct reclaim. However, if a slab is
being used for atomic allocations, there is a chance that it's the
atomic request that allocates a new page for the slab.

Larry, can you post the contents of /proc/slabinfo so we can see
what size pages are being used for the kmalloc() buckets please?

Larry, you say the buffer is 700-800 bytes. Can you confirm that 800 bytes
is roughly the request size being made by ieee80211_skb_resize()?

Pekka, assuming the request size is 800 bytes, and SLUB is using order-1
pages for allocations of that size, what happened order-1 allocations
falling back to order-0 allocations as necessary. That logic exists,
right? If so, could it be broken?

That logic is in allocate_slab() and if the higher order allocation
fails, we fall-back to struct kmem_cache ->min order. That in turn is
set up in calculate_sizes() to get_order(size) so it seems pretty
unlikely to me the allocation is 800 bytes. Of course, I could be
missing something here and there's a bug in oo_make() or oo_order().
Hmm.

Is there any chance you could hatchet together a patch
slab-allocation-failure that reports on slab allocation failures similar
to what the page allocator does? Minimally, it should tell us what
the size of the allocation was but any other information such as the
same of the slab, the size of pages it normally uses are, etc. would
also be useful.

Issue is still present. Unfortunately I've not yet seen any reaction from

Hi Pekka,

Yes, it's been looked at and discussed on the cpufreq ML. The short
answer is that they plan to re-engineer cpufreq and remove the policy
rwlock taken around almost every operations at the cpufreq level.

The short-term solution, which is recognised as ugly, would be do to the
following before doing the cancel_delayed_work_sync() :

unlock policy rwlock write lock

lock policy rwlock write lock

It basically works because this rwlock is unneeded for teardown, hence
the future re-work planned.

I'm sorry I cannot prepare a patch current... I've got quite a few pages
of Ph.D. thesis due for the beginning of July.

Thanks,

Mathieu

It would not just postpone the problem, it would also
bring the system closer to a state where kswapd does
something about the order-1 free areas.

This might postpone the problem indefinately.

Currently the system fails early, without kswapd
kicking in and freeing new order-1 areas.

The system is not generating the failures at the moment, but here is
the current state:

For some of the failures, the size was in the 700-800 range, but the
ones I found in my logs called pskb_expand_head() with skb->data_len
of 1962. For those calls, head_need and tail_need were both 0.

How do you figure it does not just postpone the problem? If there are a batch
of order-1 allocations that come in like this, it will eventually deplete
the higher-order pages and then fail because kswapd is not getting woken up.

Minimally, if we were to ignore the watermarks, there would need to be logic
that says

	"If a high-order allocation would fail due to high-order watermarks
	not being met, but the watermarks are ok from an order-0 perspective
	and the high-order page is available, then grant the allocation but
	wake up kswapd as if the order-1 allocation had failed to get the
	high-order watermarks back in shape"

If the allocation was granted, then kswapd will still not kick in.

Would something like this be sufficient? Figuring out the actual _size_ 
passed to kmalloc() is pretty difficult as then we would need to do the 
NULL test in fastpath code or pass the argument deeper in the call-chain.

It's much better than nothing. In the event of an allocation failure, we'll
know which kmalloc bucket it's coming out of so we'll have a limited range
of possible buffer sizes.

I have some suggestions on what we're outputting though.

size could be almost anything here for a casual reader. You are
outputting the size of the object plus its metadata so the name should
reflect that. I think it would be better to output objsize= and the
object size without the metadata overhead. What do you think?

In addition, include how many objects there are per-slab and include what
the order is being passed to the page allocator when allocating new slabs.
Would that be enough to determine if fallback-to-smaller orders occured?

I'm kinda scared to touch this code at all for .30 due to the number of
unexpected gotchas we seem to run into every time we touch something
locking related.  So I'm inclined to just live with the lockdep warning
for .30, and see how the real fixes look for .31, and push them back
as -stable updates if they work out.


Venki, what are your thoughts?

There is a per slab counter ORDER_FALLBACK that is increased for
allocations that required fallback.

Hi Dave,

I've looked through the cpufreq code, and the following patch should
address the call site I've missed in commit 
42a06f2166f2f6f7bf04f32b4e823eacdceafdc9. I've followed all
__cpufreq_set_policy call sites within cpufreq.c to make sure they all
hold the rwsem write lock. An extra round of review would be good
though.

Can someone try the following patch and see if it fixes the regression ?
My test machine is currently busy running long formal verifications, and
therefore unavailable for kernel patch testing. It compiles fine on a
2.6.30-rc5 kernel with my (now mainlined) cpufreq patches applied.

remove rwsem lock from CPUFREQ_GOV_STOP call (second call site)

commit	42a06f2166f2f6f7bf04f32b4e823eacdceafdc9

Missed a call site for CPUFREQ_GOV_STOP to remove the rwlock taken around the
teardown. To make a long story short, the rwlock write-lock causes a circular
dependency with cancel_delayed_work_sync(), because the timer handler takes the
read lock.

Note that all callers to __cpufreq_set_policy are taking the rwsem. All sysfs
callers (writers) hold the write rwsem at the earliest sysfs calling stage.

However, the rwlock write-lock is not needed upon governor stop.

I suspect this bit of code in dmaengine is the culprit:

	/* redistribute available channels */
	n = 0;
	for_each_dma_cap_mask(cap, dma_cap_mask_all)
		for_each_online_cpu(cpu) {
			if (num_possible_cpus() > 1)
				chan = nth_chan(cap, n++);
			else
				chan = nth_chan(cap, -1);

Why does num_possible_cpus() == 1 have to be a special case?

When there will only be one cpu the channel allocation policy changes from:
"isolate a channel per cpu"
...to:
"isolate a capability per channel".

For example, isolating per channel allows a memcpy to run concurrently
with an xor.

This change is same as the patch that I was testing right now.
Only additional change I had was a comment for cpu_policy_rwsem

  *   are concerned with are online after they get the lock.
  * - Governor routines that can be called in cpufreq hotplug path
should not
  *   take this sem as top level hotplug notifier handler takes this.

remove rwsem lock from CPUFREQ_GOV_STOP call (second call site)

commit	42a06f2166f2f6f7bf04f32b4e823eacdceafdc9

Missed a call site for CPUFREQ_GOV_STOP to remove the rwlock taken around the
teardown. To make a long story short, the rwlock write-lock causes a circular
dependency with cancel_delayed_work_sync(), because the timer handler takes the
read lock.

callers (writers) hold the write rwsem at the earliest sysfs calling stage.

The current system has not been up very long and does not show the
fragmentation:

finger@larrylap:~/wireless-testing> cat /proc/buddyinfo
Node 0, zone      DMA      4      5      4      2      4      1      2

    17     14     12    262

After I did a git pull and a kernel build with the sources on an
NFS-mounted volume, the fragmentation increased:

Re: [Bug #13116] Can't boot with nosmp

[Stephen Hemminger]

I did some more debugging, and the problem appears to be that
booting with nosmp still leaves all the CPU's present in the cpu
possible mask. So code like dma engine (or loopback device), that
use alloc_percpu get broken.

Not sure why all the cpu's are still showing up in the possible mask.
Rusty? do you have an answer.

Well, if the slab_out_of_memory() is called, we already know the
higher order allocation failed _and_ the fallback allocation failed.
So yes, it would be enough.

Larry reported this stack trace:

kernel: git: page allocation failure. order:1, mode:0x4020
kernel: Pid: 3707, comm: git Not tainted 2.6.30-rc1-wl #115
kernel: Call Trace:
kernel:  [<ffffffff80292f84>] __alloc_pages_internal+0x43d/0x45d
kernel:  [<ffffffff802b2383>] alloc_pages_current+0xbe/0xc6
kernel:  [<ffffffff802b66a4>] new_slab+0xcf/0x28b

That's in the order fallback for new slab allocations; so this cache must 
have oo_order(s->min) of 1.

To diagnose whether its object size dictates a >0 slab order, you could 
enable CONFIG_SLUB_STATS (it's disabled in his .config) and check which 
/sys/kernel/slab/cache/order_fallback increased.  Once you have identified 
the cache, you can get this information via 
/sys/kernel/slab/cache/{objsize,order,size}.  I think this is what 
Christoph was getting at.

You could even boot with `slub_nomerge' to determine whether cache merging 
was the issue where the cache under consideration was unnecessarily merged 
with one that requires larger higher order minimums.

I don't quite understand how its necessary to print the partial lists for 
each node, they should be exhausted if we're allocating a new slab if the 
node doesn't matter (and can't in Larry's case, he only has one).

Yes, agreed which is why I said it's unlikely that the allocated size is
800 bytes or so.

Sure. Applying my diagnostic patch will probably shed some light on the
subject too.

It doesn't hurt either, does it? Yes, we expect the partial lists to be
exhausted but it's better to print that out just in case we have a bug
some day somewhere and that condition is not true. This is very
infrequent slow patch code here anyway.

I wasn't sure whether you were proposing the patch as an addition to slub 
or just to help with this issue.  I agree it would help in a hopefully 
ratelimited manner for general slab allocation failures and would have 
avoided some of the confusion for this issue from lack of diagnostics.

It will lead to false postiives since you can get a free to a full slab 
which moves it back to an allowed node's partial list before count_free() 
is printed.

I am proposing it as a generic addition to SLUB.

Would this recent commit also fix this issue?

commit a4c0364be3f43d3e17fe19270f8b3d64881606e6
Author: Avi Kivity <avi@redhat.com>
Date:   Sat Jun 6 12:34:39 2009 +0300

    KVM: Explicity initialize cpus_hardware_enabled

    Under CONFIG_MAXSMP, cpus_hardware_enabled is allocated from the heap and
    not statically initialized.  This causes a crash on reboot when kvm thinks
    vmx is enabled on random nonexistent cpus and accesses nonexistent percpu
    lists.

    Fix by explicitly clearing the variable.

This only affects reboots.  But yes, the cpumask code has bugs.  Does 
the .config involved select MAXSMP?

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

Patch does not fix the problem. Not sure if it is KVM only problem.
Look like possible cpumask always equals what ACPI / SMP tables report.
So currently looking into alloc_percpu which may not handle the possible
but never used cpus.

It is x86-64 config and does not have MAXSMP set. It does have NR_CPUS set.

Right, it shouldn't have.

So it's not cpumask.  Dare I suggest a bisect?

I did some testing of different versions.

* Problem does not exist with 2.6.30-rc8 (so regression should be closed).

* Problem does exist with 2.6.29.4

* Happens with both nosmp and maxcpus=1


Given that it is fixed in 2.6.30, at this point there really is no urgency
to spend more time investigating the issue. There are certainly bigger problems
to deal with.

With the above patch installed, I pushed my system hard enough to get
the O(1) allocation failures. This time they were triggered with a
'make -j8' on the kernel. No, I don't have that many CPUs, but I
figured that the extra make jobs might stress memory. My kernel is
2.6.30-rc8 from the wireless-testing tree. Everything matches Linus's
tree except drivers/net/wireless/, which contains what is essentially
2.6.31 code.

The dmesg output starting with the first allocation failure is:

Aha, SLUB thinks the minimum order for 4096 is 1. I guess you have
CONFIG_SLUB_DEBUG enabled? If yes, something like to following should
help. Christoph, are you okay with this patch?

? Or is this a path that only happens for small allocations?

Much nicer. There is a clear division between the object size and the
size including the metadata. There is also now a good idea of what sort
of request it was, we know what cache it was so we can guess the size
passed to kmalloc() with reasonable accuracy.

That looks like it would generate easier-to-debug-with messages and to
not-expert-at-slub eye, it looks correct. Slap a changelog on it with an
example message and go with it.  It should make page allocation failures
messages that go through SLUB a lot easier to figure out.

Anything that's beyond PAGE_SIZE * 2 is passed straight to the page
allocator and the intent of this patch is to disable debugging for all
big caches like SLAB does.

He likely has CONFIG_SLUB_DEBUG_ON set which enables debugging and thus
needs more than the payload for metadata.

Yup. I suspect a lot of people who are doing _testing_ enable that. If
you're unhappy with my patch (the get_order one which shouldn't affect
that many caches anyway), any suggestions how to fix this up? It seems
that the wireless stack at least does quite a few kmalloc(4096)
allocations.

We can probably switch back to page allocator pass-through in the near
future (when Mel's patches are in) but we need a fix for -stable.

Thanks for the lockdep reports,

I'm currently looking into it, and it's not pretty. Basically we have :

A
  B
(means B nested in A)

work
  read rwlock policy

dbs_mutex
  work
    read rwlock policy

write rwlock policy
  dbs_mutex

So the added dbs_mutex <- work <- rwlock policy dependency (for proper
teardown) is firing the reverse dependency between policy rwlock and
dbs_mutex.

The real way to fix this is to do not take the rwlock policy around
non-policy-related actions, like governor START/STOP doing worker
creation/teardown.

One simple short-term solution would be to take a mutex outside of the
policy rwlock write lock in cpufreq.c. This mutex would be the
equivalent of dbs_mutex "lifted" outside of the rwlock write lock. For
teardown, we only need to hold this mutex, not the rwlock write lock.
Then we can remove the dbs_mutex from the governors.

But looking at cpufreq.c's cpufreq_add_dev() is very much like kicking a
wasp nest: a lot of error paths are not handled properly, and I fear
someone will have to go through the code, fix the currently incorrect
code paths, and then add the lifted mutex.

I currently have no time for implementation due to my thesis, but I'll
be happy to review a patch.

I think networking rounds up allocations, but it's not wireless per se.

How about below patch on top of Mathieu's patch here
http://marc.info/?l=linux-kernel&m=124448150529838&w=2

[PATCH] cpufreq: Eliminate lockdep issue with dbs_mutex and policy_rwsem

This removes the unneeded dependency of 
write rwlock policy
  dbs_mutex

dbs_mutex does not have anything to do with timer_init and timer_exit. It
is just to protect dbs tunables in sysfs cpufreq/ondemand and is not
needed to be held during timer init, exit as well as during governor limit
changes.

If this works, then it will likely need to be ported to the conservative
governor too.

The ondemand locking very much looks like taken over from the userspacegovernor. There you need the lock because a write to set_speed directlycalls ->target.
What is urgently missing is a description for what the locks arereally used, not only in which case they deadlock.
>From your comment above:> dbs_mutex does not have anything to do with timer_init and timer_exit.But this is what it seems to do?If it's not needed to protect calling timer_init while in timer_exit(or the other way around) and sysfs_create_group whilein sysfs_remove_group I think the mutex can be deleted.What do you think about this patch (compile tested only and notfor .30)?
Is someone aware of any test scenarios I could run to try withoutthe mutex and run into trouble?Do I totally miss something here or does this make sense?
Thanks,

CPUFREQ ondemand: Remove unneeded dbs_mutex
There is no need to protect general (not per core) ondemand sysfs variablesagainst per core governor (de-)activation (GOV_START/GOV_STOP).
It must just be assured that these are only initialized once, before userspacecan modify them (otherwise userspace modifications will be overriden byre-initializing the general variables).This should already be the case.

I was looking at the same thing before sending the patch yesterday. I
don't think the dbs_lock is similar to userspace lock. Infact, I don't
think we need the lock in userspace case, as we will already be holding
policy rwsem in cpufreq, before calling setspeed. But thats a different
story.

The reason I left dbs_mutex as is and just removed the init/exit timer
outside the lock was because of the non typical sysfs usage in ondemand.
We have dbs_attr_group that gets added under each cpu's cpufreq
directory, but they are controlling a single set of ondemand variables.
This mutex is just serializing the changes to those variables. I could't
think of any functionality issues of not having the lock as such.
