One quick observation is that pretty much all the OOMed allocations
in your log are in readahead (swap and VM). Perhaps we should throttle
readahead when the system is under high memory pressure?

(copying Fengguang)	

On theory on why it could happen more often with dm_crypt is that
dm_crypt increases the latency, so more IO will be in flight.

Another thing is that the dmcrypt IOs will likely do their own
readahead, so you may end up with multiplied readahead 
from several levels. Perhaps we should disable RA for the low level
encrypted dmcrypt IOs?

One thing I would try is to disable readahead like in this patch
and see if it solves the problem.

It would be probably better to not do the allocations at all under 
memory pressure.  Even if the RA allocation doesn't go into reclaim
it may still "steal" allocations recently freed and needed by other
actors.

Fair enough.
I think we can do it easily now.
If page_cache_alloc_readahead(ie, GFP_NORETRY) is fail, we can adjust
RA window size or turn off a while. The point is that we can use the
fail of __do_page_cache_readahead as sign of memory pressure.
Wu, What do you think?

This problem is general thing as well as RA.
But it would be not a big problem in order-0 pages.
If it's a really problem, it might sign we have to increase SWAP_CLUSTER_MAX.

The concern I thought is order-0 allocation happens with other
higher-order reclaims in parallel.
order-0 allocation can steal other's high order pages.
For it, I sent a patch but I didn't have enough time to dig in.
https://lkml.org/lkml/2011/5/2/93
I have a plan to do.

No, disabling readahead can hardly help.

The sequential readahead memory consumption can be estimated by

                2 * (number of concurrent read streams) * (readahead window size)

And you can double that when there are two level of readaheads.

Since there are hardly any concurrent read streams in Andy's case,
the readahead memory consumption will be ignorable.

Typically readahead thrashing will happen long before excessive
GFP_NORETRY failures, so the reasonable solutions are to

- shrink readahead window on readahead thrashing
  (current readahead heuristic can somehow do this, and I have patches
  to further improve it)

- prevent abnormal GFP_NORETRY failures
  (when there are many reclaimable pages)


Andy's OOM memory dump (incorrect_oom_kill.txt.xz) shows that there are

- 8MB   active+inactive file pages
- 160MB active+inactive anon pages
- 1GB   shmem pages
- 1.4GB unevictable pages

Hmm, why are there so many unevictable pages?  How come the shmem
pages become unevictable when there are plenty of swap space?

Thanks,
Fengguang

I have no clue, but this patch (from Minchan, whitespace-damaged) seems to help:

I haven't tested it very thoroughly, but it's survived much longer
than an unpatched kernel probably would have under moderate use.

I have no idea what the patch does :)

I'm happy to run any tests.  I'm also planning to upgrade from 2GB to
8GB RAM soon, which might change something.

The reason I sent this is that I think your problem is similar to
recent Jame's one.
https://lkml.org/lkml/2011/4/27/361

What the patch does is [1] fix of "wrong pgdat_balanced return value"
bug and [2] fix of "infinite kswapd bug of non-preemption kernel" on
high-order page.

About [1], kswapd have to sleep if zone balancing is completed but in
1741c877[mm: kswapd: keep kswapd awake for high-order allocations
until a percentage of the node is balanced], we made a mistake that
returns wrong return.
Then, although we complete zone balancing, kswapd doesn't sleep and
calls balance_pgdat. In this case, balance_pgdat rerurns without any
work and kswapd could repeat this work infinitely.

If it turns out the patch works (which is patches 1 and 4 from the
series related to James) for more than one tester, I'll push it
separately and drop the SLUB changes.

That was probably because one of my testcases creates a 1.4GB file on
ramfs.  (I can provoke the problem without doing evil things like
that, but the test script is rather reliable at killing my system and
it works fine on my other machines.)

If you want, I can try to generate a trace that isn't polluted with
the evil ramfs file.

Ah I didn't read your first email.. I'm now running

./test_mempressure.sh 1500 1400 1

with mem=2G and no swap, but cannot reproduce OOM.

What's your kconfig?

No, thanks. However it would be valuable if you can retry with this
patch _alone_ (without the "if (need_resched()) return false;" change,
as I don't see how it helps your case).

Yes. I was curious about that. The experiment would be very valuable.

In case of James, he met the problem again without need_resched.
https://lkml.org/lkml/2011/5/12/547.

But I am not sure what's exact meaning of 'livelock' he mentioned.
I expect he met softlockup, again.

Still I think the possibility that skip cond_resched spared in
vmscan.c is _very_ low. How come such softlockup happens?
So I am really curious about what's going on under my sight.

Do you have a Sandy Bridge laptop?  There was a recent thread on lkml
suggesting that only Sandy Bridge laptops saw this problem.  Although
there's something else needed to trigger it, because I can't do it
from an initramfs I made that tried to show this problem.

Attached.  This is 2.6.38.6.

Done.

I logged in, added swap, and ran a program that allocated 1900MB of
RAM and memset it.  The system lagged a bit but survived.  kswapd
showed 10% CPU (which is odd, IMO, since I'm using aesni-intel and I
think that all the crypt happens in kworker when aesni-intel is in
use).

Then I started Firefox, loaded gmail, and ran test_mempressure.sh.
Kaboom!  (I.e. system was hung)  SysRq-F saved the system and produced
the attached dump.  I had 6GB swap available, so there shouldn't have
been any OOM.

I think kswapd could use 10% enough for reclaim.

Hang?
It means you see softhangup of kswapd? or mouse/keyboard doesn't move?

Yes. It's strange but we have seen such case several times, AFAIR.

Let see your first OOM message.
(Intentionally, I don't inline OOM message as Web Gmail mangles it and
whoever see it is very annoying.)

If it consider min/low/high of zones, any zones can't meet your
allocation request. (order-0, GFP_WAIT|IO|FS|HIGHMEM). So the result
is natural.
But thing I wonder is that we have lots of free swap space as you said.
Why doesn't VM swap out anon pages of DMA32 zone and then happen OOM?

We are going to isolate anon pages of DMA32 as log said(ie,
isolated(anon):408kB)
So I think VM is going on rightly.
The thing is task speed of request allocation is faster than swapout's
speed. So swap device is very congested and most of swapout pages
would remain PG_writeback. In the end, shrink_page_list returns 0.

In high-order page reclaim, we can adjust task's speed by should_reclaim_stall.
But for order-0 page, should_reclaim_stall returns _false_ and at last
we can see OOM message although swap has lots of free space.
Does my guessing make sense?
If it is, does it make sense that OOM happens despite we have lots of
swap space in case of order-0?
How about this?

Andrew, Could you test this patch with !pgdat_balanced patch?
I think we shouldn't see OOM message if we have lots of free swap space.

With this patch, I started GNOME and Firefox, turned on swap, and ran
test_mempressure.sh 1500 1400 1.  Instant panic (or OOPS and hang or
something -- didn't get the top part).  Picture attached -- it looks
like memcg might be involved.  I'm running F15, so it might even be
doing something.

I won't be able to get netconsole dumps until next week because I'm
out of town and only have this one computer here.

I haven't tried the other patch.

Also, the !pgdat_balanced fix plus the if (need_resched()) return
false patch just hung once on 2.6.37-rc9.  I don't know what triggered
it.  Maybe yum.

Hmm, what kernel version do you use ?
I think memcg is not guilty because RIP is shrink_page_list().
But ok, I'll dig this. Could you give us your .config ?

Thanks,

Attached.

The address in shrink_page_list is ud2, from (I think)
VM_BUG_ON(PageActive(page));.  The sequence is:

   0xffffffff810d24cc <+202>:	callq  0xffffffff810cf930 <test_and_set_bit>
   0xffffffff810d24d1 <+207>:	test   %eax,%eax
   0xffffffff810d24d3 <+209>:	jne    0xffffffff810d2aa5 <shrink_page_list+1699>
   0xffffffff810d24d9 <+215>:	mov    -0x28(%rbx),%rax
   0xffffffff810d24dd <+219>:	test   $0x40,%al
   0xffffffff810d24df <+221>:	je     0xffffffff810d24e3 <shrink_page_list+225>
   0xffffffff810d24e1 <+223>:	ud2

I cannot figure out why happens OOPS.
Let me know your kernel version and config.
Kame. Is there anything related to memcg you guess?

In addition, the patch I give was utterly stupid.
The goal is that we wait dirty page writeback in (order-0 | high
priority) reclaim.
(But I don't think it's ideal solution in this problem but just for
proving the problem)
But although we pass sync with 1 in set_reclaim_mode, it ignores.
So fix is following as. (NOTICE: It doesn't related to your OOPS. )
But before further experiment, let's fix your oops.

No problem. :)
We should avoid OOPS for the experiment.

Thanks for the good information.
It seems need_resched patch isn't good candidate to fix current problem.
We already weeded it out.

Thank you very much for the testing!

I just booted 2.6.38.6 with exactly two patches applied.  Config was
the same as I emailed yesterday.  Userspace is F15.  First was
"aesni-intel: Merge with fpu.ko" because dracut fails to boot my
system without it.  Second was this (sorry for whitespace damage):

I started GNOME and Firefox, enabled swap, and ran test_mempressure.sh
1500 1400 1.  The system quickly gave the attached oops.

The oops was the ud2 here:

   0xffffffff810d251f <+219>:	test   $0x40,%al

Please let me know what the next test to run is.

Okay. My first patch(!pgdat_balanced and cond_resched right after
balance_pgdat) sent you was successful. But the version removed
cond_resched was hang.

Let's not make the problem complex.
So let's put aside the above my patch.

Would you be willing to test one more with below patch?
(Of course, it would be damage by white space. I can't do anything for
it in my office. Sorry.)
If below patch still fix your problem like my first patch, we will
push this patch into mainline.

Thanks. Andrew.

I haven't applied Minchan's latest patch yet, but given the OOPS it
seems like the root cause might be something other than kswapd not
going sleep.  So I applied this additional patch:

Right after that happened, I hit ctrl-c to kill test_mempressure.sh.
The system was OK until I typed sync, and then everything hung.

I'm really confused.  shrink_inactive_list in
RECLAIM_MODE_LUMPYRECLAIM will call one of the isolate_pages functions
with ISOLATE_BOTH.  The resulting list goes into shrink_page_list,
which does VM_BUG_ON(PageActive(page)).

How is that supposed to work?

Usually clear_active_flags() clear PG_active before calling shrink_page_list().

shrink_inactive_list()
     isolate_pages_global()
     update_isolated_counts()
         clear_active_flags()
     shrink_page_list()

That makes sense.  And I have CONFIG_COMPACTION=y, so the lumpy mode
doesn't get set anyway.

But the pages I'm seeing have flags=100000000008005D.  If I'm reading
it right, that means locked,referenced,uptodate,dirty,active.  How
does a page like that end up in shrink_page_list?  I don't see how a
page that's !PageLRU can get marked Active.  Nonetheless, I'm hitting
that VM_BUG_ON.

Is there a race somewhere?

Could you see the problem with disabling CONFIG_COMPACTION?

Thanks for proving that it's not a problem of latest my patch.

> Is there a race somewhere?

First of all, let's finish your first problem about hang. :)
And let's make another thread to fix this problem.

I think this is a severe problem because 2.6.39 includes my deactivate_pages
(http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=315601809d124d046abd6c3ffa346d0dbd7aa29d)

It touches page states more and more. (2.6.38.6 doesn't include it so
it's not a problem of my deactivate_pages problem)
And now inorder-putback series which I will push for 2.6.40 touches it
more and more.

So I want to resolve your problem asap.
We don't have see report about that. Could you do git-bisect?
FYI, Recently, big change of mm is compaction,transparent huge pages.
Kame, could you point out thing related to memcg if you have a mind?

I don't doubt memcg at this stage because it never modify page->flags.
Consdering the case, PageActive() is set against off-LRU pages after
clear_active_flags() clears it.

Hmm, I think I don't understand the lock system fully but...how do you
think this ?

==

At splitting a hugepage, the routine marks all pmd as "splitting".

But assume a racy case where 2 threads run into spit at the
same time, one thread wins compound_lock() and do split, another
thread should not touch splitted pages.

Sorry. Now I don't have a time to review in detail.
When I look it roughly,  page_lock_anon_vma have to prevent it.
But Andrea needs current this problem and he will catch something we lost. :)

If you turn this into a BUG_ON(!PageCompound)) I'm ok with it. But it
wasn't supposed to ever happen so the above shouldn't be needed.

This very check is done in split_huge_page after taking the root
anon_vma lock. And every other thread or process sharing the page has
to take the anon_vma lock, and then check PageCompound too before it
can proceed into __split_huge_page. So I don't see a problem but
please add the BUG_ON if you are concerned. A BUG_ON definitely can't
hurt. Also note, __split_huge_page is static and is only called by
split_huge_page which does the check after proper locking.

    if (!PageCompound(page))

I figure it's not easily reproducible but you can easily rule out THP
issues by reproducing at least once after booting with
transparent_hugepage=never or by building the kernel with
CONFIG_TRANSPARENT_HUGEPAGE=n.

I'm afraid we might have some lru active/inactive/isolated vmstat.c
related issue so that's the part of the code I'd recommend to review
(I checked it and I didn't see wrong stuff yet, not even in THP
context yet but I'm still worried we have a statistic issue
somewhere). I had a bugreport during -rc by two people (one was UP
build and one was SMP build) not easily reproducible too, that hinted
a possible nr_inactive* or nr_inactive* (or both) being wrong (not
sure if _anon or _file, could be just one lru type or both). If stats
are off, that may also trigger oom killer by making the VM shrinking
(which also activates the swapping) bail out early thinking it can't
shrink no more. It could be the same statistic problem that sometime
makes the VM think it can't shrink no more and lead into early oom
killing, and at other times it loops indefinitely in too_many_isolated
if nr_isolated_X > nr_inactive_X indefinitely for __GFP_NO_KSWAPD
allocations (kswapd is immune from such loop, so if kswapd is allowed
to run, it probably kswapd then increases nr_inactive by deactivating
enough pages to make it unblock). Just a wild guess...

Reproduced with CONFIG_TRANSPARENT_HUGEPAGE=n with and without
compaction and migration.

I applied the attached patch (which includes Minchan's !pgdat_balanced
and need_resched changes).  I see:

This is interesting: it looks like shrink_page_list is making its way
through the list more than once.  It could be reentering itself
somehow or it could have something screwed up with the linked list.

I'll keep slowly debugging, but maybe this is enough for someone
familiar with this code to beat me to it.

Minchan, I think this means that your fixes are just hiding and not
fixing the underlying problem.

Could you test with below patch?

If this patch fixes it, I don't know why we see this problem now.
It should be problem long time ago.

I'm now running that patch *without* the pgdat_balanced fix or the
need_resched check.  The VM_BUG_ON doesn't happen but I still get
incorrect OOM kills.

However, if I replace the check with:

	if (false &&should_reclaim_stall(nr_taken, nr_reclaimed, priority, sc)) {

then my system lags under bad memory pressure but recovers without
OOMs or oopses.

Is that expected?

Instead of it, could you test shrink_slab patch with !pgdat_balanced?

I agree you can see OOM but oops? Did you see any oops?

No..  :(

It's totally opposite.
That routine is for getting the memory althought we lose latency
It's another issue. :(

No oops.  I've now reproduced the OOPS with both the if (false) change
and the clear_active_flags change.

Also, would this version be better?  I think your version overcounts
nr_scanned, but I'm not sure what effect that would have.

Minchan,

I'm confused now.
If pages got SetPageActive(), should_reclaim_stall() should never return true.
Can you please explain which bad scenario was happen?

I did some tracing and the oops happens from the second call to
shrink_page_list after should_reclaim_stall returns true and it hits
the same pages in the same order that the earlier call just finished
calling SetPageActive on.  I have *not* confirmed that the two calls
happened from the same call to shrink_inactive_list, but something's
certainly wrong in there.

This is very easy to reproduce on my laptop.

Can you please share your tracing patch and raw tracing result log?

I would like to confirm this problem.
Could you show the diff of 2.6.38.6 with current your 2.6.38.6 + alpha?
(ie, I would like to know that what patches you add up on vanilla
2.6.38.6 to reproduce this problem)
I believe you added my crap below patch. Right?

Bah.  It's this last hunk.  Without this I can't reproduce the oops.
With this hunk, the reset_reclaim_mode doesn't work and
shrink_page_list is incorrectly called twice.

So we're back to the original problem...

OMG! I should have said more clearly to you.  Above my patch is totally _crap_.
I thought you have experimented test without above crap patch. :(
Sorry for consuming time of many mm guys.
My apologies.

I want to resolve your original problem(ie, hang) before digging the
OOM problem.

>
> So we're back to the original problem...

Could you test below patch based on vanilla 2.6.38.6?
The expect result is that system hang never should happen.
I hope this is last test about hang.

Thanks.

It looks cleaner to return -1 here to differentiate the failure in
taking the lock from when we take the lock and just 1 object is
freed. Callers seems to be ok with -1 already and more intuitive for
the while (nr > 10) loops too (those loops could be changed to "while
(nr > 0)" if all shrinkers are accurate and not doing something
inaccurate like the above code did, the shrinkers retvals I didn't
check yet).

If we enter the loop some of the shrinkers will reschedule but it
looks good for the last iteration that may have still run for some
time before returning. The actual failure of shrinker_rwsem seems only
theoretical though (but ok to cover it too with the cond_resched, but
in practice this should be more for the case where shrinker_rwsem
doesn't fail).

I now wonder if this is why compaction in kswapd didn't work out well
and kswapd would spin at 100% load so much when compaction was added,
plus with kswapd-compaction patch I think this code should be changed
to:

 if (!COMPACTION_BUILD && order)
  return !pgdat_balanced();
 else
  return !all_zones_ok;

(but only with kswapd-compaction)

I should probably give kswapd-compaction another spin after fixing
this, because with compaction kswapd should be super successful at
satisfying zone_watermark_ok_safe(zone, _order_...) in the
sleeping_prematurely high watermark check, leading to pgdat_balanced
returning true most of the time (which would make kswapd go crazy spin
instead of stopping as it was supposed to). Mel, do you also think
it's worth another try with a fixed sleeping_prematurely like above?

Another thing, I'm not excited of the schedule_timeout(HZ/10) in
kswapd_try_to_sleep(), it seems all for the statistics.

Thanks,
Andrea

Only one caller reads the value of shrink_slab() and while it would
survive -1 being returned, it gains nothing. I don't see it as being
much clearer than the existing return value of 1.

Yes.

Profiles from some users imply that this condition is being hit. I
can't 100% prove it as I can't reproduce the problem locally
(seems to require a sandybridge laptop for some reason). Tests did
show that kswapd CPU usage was reduced as well as the liklihood
of hanging when shrink_slab used cond_resched() like this. See
https://lkml.org/lkml/2011/5/17/274 .

Why? kswapd can enter lumpy reclaim when !COMPACTION_BUILD. While this
is hardly desirable, I don't see why kswapd should use different logic
for balancing depending on whether compaction is used or not.

It's worth a try anyway although I think it's more important to figure
out if all_unreclaimable is being improperly set or not.

It's to catch where kswapd balances a zone but continual allocations put
the zone under the high watermark quickly. It's to keep kswapd awake to
reduce the likelihood that processes get hit the min watermark and
stall.

So far with this patch I can't reproduce the hang or the bogus OOM.

To be completely clear, I have COMPACTION, MIGRATION, and THP off, I'm
running 2.6.38.6, and I have exactly two patches applied.  One is the
attached patch and the other is a the fpu.ko/aesni_intel.ko merger
which I need to get dracut to boot my box.

For fun, I also upgraded to 8GB of RAM and it still works.

Hmm. Could you test it with enable thp and 2G RAM?
Isn't it a original test environment?
Please don't change test environment. :)

Thanks for your effort, Andrew.

The test that passed last night was an environment (hardware and
config) that I had confirmed earlier as failing without the patch.

I just re-tested my original config (from a backup -- migration,
compaction, and thp "always" are enabled).  I get bogus OOMs but not a
hang.  (I'm running with mem=2G right now -- I'll swap the DIMMs back
out later on if you want.)

I attached the bogus OOM (actually several that happened in sequence).
 They look readahead-related.  There was plenty of free swap space.

Unfortnately, this log don't tell us why DM don't issue any swap io. ;-)
I doubt it's DM issue. Can you please try to make swap on out of DM?

I noticed that the test script mounted a "ramfs" not "tmpfs", hence
the 1.4G pages won't be swapped?

That's intentional.

I run LVM over dm-crypt on an SSD, and I thought that might be part of
the problem.  I wanted a script that would see if I could reproduce
the problem without stressing that system too much, so I created a
second backing store on dm-crypt over ramfs so that no real I/O will
happen.  The script is quite effective at bringing down my system, so
I haven't changed it.

(I have 6GB of "real" swap on the LVM, so pinning 1500MB into RAM
ought to cause some thrashing but not take the system down.  And this
script with a larger ramfs does not take down my desktop, which is an
8GB Sandy Bridge box.  But whatever the underlying bug is seems to
mainly affect Sandy Bridge *laptops*, so maybe that's expected.)

Right. ramfs pages can not be swapped out.
But in log, anon 200M in DMA32 doesn't include unevictable 1.4GB.
So we can swap out 200M, still.

I don't mean we have to disable RA.
As I said, the point is that we can use __GFP_NORETRY alloc fail as
_sign_ of memory pressure.

If it is, RA thrashing could be better sign than failure of __GFP_NORETRY.
If we can do it easily, I don't object it. :)

Good to hear. :)
I don't want RA steals high order page in memory pressure.
My patch and shrinking RA window helps this case.

Yeah, the RA thrashing is much better sign because it not only happens
long before normal __GFP_NORETRY failures, but also offers hint on how
tight memory pressure it is. We can then shrink the readahead window
adaptively to the available page cache memory :)

More often than not it won't be RA's fault :)  When you see RA page
allocations stealing high order pages, it may actually be reflecting
some more general order-0 steal order-N problem..

Agree.
As I said to Andy, it's a general problem but RA has a possibility to
reduce it while others don't have a any solution. :(
