Re: OOM-killer and strange RSS value in 3.9-rc7

[Michal Hocko]

[CCing SL.B people and linux-mm list]

Just for quick summary. The reporter sees OOM situations with almost
whole memory filled with slab memory. This is a powerpc machine with 4G
RAM.
/proc/slabinfo shows that almost whole slab occupied memory is on
free lists which for some reason don't get freed under memory pressure.
kmalloc-* caches seem to be most affected. For reference:
$ awk '{active_size=$2*$4;num_size=$3*$4;active_sum+=active_size;num_sum+=num_size; printf "%s: %d %d\n", $1, active_size, num_size}END{printf "sum: %d %d\n", active_sum, num_sum}' a | sort -k3 -n | tail -n10
kmemleak_object: 94664384 112746000
pgtable-2^12: 107937792 113246208
kmalloc-8192: 59334656 122159104
kmalloc-32768: 36175872 137887744
task_struct: 27080016 241293920
kmalloc-2048: 17317888 306446336
kmalloc-96: 8734848 307652928
kmalloc-16384: 54919168 516620288
kmalloc-512: 17211392 1226833920
sum: 865488272 3598335904

It is not clear who consumes that memory and the reporter claims this is
vanilla 3.9-rc7 kernel without any third party modules loaded. The issue
seems to be present only with CONFIG_SLUB.

The following is right after boot or make -j64?

Could you send the full config which you are using right now, please?
Also the full dmesg output since boot might turn up helpful.

Boot with "slub_debug" or enable slab debugging.

Please enable debugging and look at where these objects were allocated.

cat /sys/kernel/slab/kmalloc-*/alloc_calls

will show where these objects are allocated.

A dump of the other fields in /sys/kernel/slab/kmalloc*/* would also be
useful.

Age refers to the mininum / avg / maximum age of the object in ticks.

pid refers to the range of pids by processes running when the objects were
created.

cpus are the processors on which kernel threads where running when these
objects were allocated.

Why need monitor the age of the object?

Will give you some idea as to when these objects were created.

Thanks for your clarify. ;-) But why mininum / avg / maximum instead of 
a single value?

You can see the age of the oldest and youngest object.

It seems that age = jiffies - track->when; can't accurately describe age 
of each used object in one slab. The objects in one slab should be same 
age in current logic, but jiffies are changed when each time enter into 
add_location.

The objects could be allocated at any time. The track structure is per
object not per slab.

The "age" refers to the time in jiffies since object allocation.

Ok that looks like a lot of objects were freed from slab pages but the
slab pages were not freed.

looking at kmalloc-8192 we have

Total capacity of the slab cache is 27k objects but only 508 are in use.

Looks like slab pages are not freed when all objects in them have been
released.

The relevant portion of code that do the freeing are in

mm/slub.c::unfreeze_partials()

		if (unlikely(!new.inuse && n->nr_partial > s->min_partial)) {
                        page->next = discard_page;
                        discard_page = page;
                } else {
                        add_partial(n, page, DEACTIVATE_TO_TAIL);
                        stat(s, FREE_ADD_PARTIAL);
                }


..

       while (discard_page) {
                page = discard_page;
                discard_page = discard_page->next;

                stat(s, DEACTIVATE_EMPTY);
                discard_slab(s, page);
                stat(s, FREE_SLAB);
        }

and mm/slub.c::__slab_free()

     if (unlikely(!new.inuse && n->nr_partial > s->min_partial))
                goto slab_empty;


Could you verify the values of nr_partial and min_partial and verify that
the free paths are actually used?

Could you give me some hints about how to verify them? Only I can do is
adding two printk() statements to print the vaules in those two

The s->min_partial is always "6" and most of n->nr_partial is bigger than 
its partner of the same line.

Ok thats good. nr->partial needs to be bigger than min_partial in order
for frees to occur. So they do occur.

Thats the way it should be. But the mystery is still there. Why do the
pages not get freed? Can you add a printk in __free_slab to verify that it
actually gets called? Print s->name to see which slab is affected by the
free.

Is there any way I can run a powerpc kernel that shows the issue on x86
with an emulator?

I added a printk() like this:

@@ -1388,6 +1388,8 @@ static void __free_slab(struct kmem_cache *s, struct page *page)
        int order = compound_order(page);
        int pages = 1 << order;

        if (kmem_cache_debug(s)) {

and it is called so many times that the boot cannot be finished. So
maybe the memory isn't freed even though __free_slab() get called?

Ok that suggests an issue with the page allocator then.

You seem to have CONFIG_MEMCG_KMEM enabled. Do you see the same issue
when this is disabled? The kmem accounting should be disabled unless a
specific limit is set but it would be better to know that this is not
the factor.

I have tested to disable CONFIG_MEMCG_KMEM. But it doesn't solve this
problem, I can still trigger the OOM by compiling kernel.

Now I suspect the problem comes from the driver "ibmvscsi". Because on another
power 7 system, which doesn't use ibmvscsi, there is no such OOM
problem here. For now, looks like only systems using ibmvscsi can
trigger this OOM problem. I have rebooted one of the ibmvscsi systems
with "init=/bin/sh" and compared the loaded modules with one of the
none-ibmvscsi system with "comm":

	$ comm -13 --check-order none-ibmvscsi.txt ibmvscsi.txt
	ibmvscsi
	nx_crypto
	scsi_transport_srp

the scsi_transport_srp is used by ibmvscsi and I can rmmod the 
nx_crypto out. Then I launched the compiling process on the
single-user-booted ibmvscsi system. The OOM can still be
produced on it.

Looks like "ibmvscsi" + "slub" can trigger this problem.

And the next merge of the slab-next tree will also cause SLAB to trigger
this issue. I would like to have this fixes. The slab allocator purpose is
to servr objects that are a fraction of a page and not objects that are
larger than the maximum allowed sizes of the page allocator.

So the problem is in memory management code, not in ibmvscis? And looks
like there is a fix already?

Both should be fixed. Making requests for large amounts of memory from an
allocator that is supposed to hand out fraction of a page does not make
sense.

Could you point to the specific commit(s), please?

AFAIR there were lots of objects in size-512 as well.

Is this still a problem with 3.9 and later kernels?  Please try to 
reproduce it on 3.13.

If it does reproduce, could you try to pinpoint the problem with kmemleak?  
Look into Documentation/kmemleak.txt which should identify where these 
leaks are coming from with your slab allocator of choice.
