In environment
  - Host: kernel-2.6.32xxx (RHEL6)
  - Guest: mm-of-the-moment snapshot 2011-02-04-15-15

I saw this when I ran make -j8 under 200M limit of memcg with 4vcpu.
But it seems this doesn't directly related to memcg or virtualization.

Anyway, log is here. I'm sorry if this is a fixed one.
My .config is attached. and a brief note is below

2nd log, "kernel BUG at include/linux/mm.h:420!" is  This one.
==
static inline void __ClearPageBuddy(struct page *page)
{
        VM_BUG_ON(!PageBuddy(page));
        atomic_set(&page->_mapcount, -1);
}
==
But this is just a tail of bad_page().
==
static void bad_page(struct page *page)
{
        static unsigned long resume;
        static unsigned long nr_shown;
        static unsigned long nr_unshown;
...
        dump_stack();
out:
        /* Leave bad fields for debug, except PageBuddy could make trouble */
        __ClearPageBuddy(page);
        add_taint(TAINT_BAD_PAGE);
}
==
So, what important is bad_page().

BAD page says

Maybe page_mapcount(page) was > 0. and ->mapping was NULL.

BTW, I think pc->flags should be printed in hex...Nishimura-san, how do you think ?


In hex, pc->flags was 7A00000000004 and this means PCG_USED bit is set.
This implies page_remove_rmap() may not be called but ->mapping is NULL. Hmm?
(7A is encoding of section number.)

make -j 8 under 200M limit is highly busy with swap.

Thanks,
-Kame

Sorry please ignore above. bad_page() used page_mapcount().

Agreed.
I don't enough time this week, so I'll prepare a patch in next week if necessary.

I'll try, and look at the issue too.

Ah, ok, this is maybe caused by this. I'm sorry that I missed this.

static inline int free_pages_check(struct page *page)
{
        if (unlikely(page_mapcount(page) |
                (page->mapping != NULL)  |

                bad_page(page);

Then, ok, this is a memcgroup and hugepage issue.

I'll look into.

There was a big bug. Anyway, thank you for adding new bad_page for memcg.
==

mem_cgroup_uncharge_page() should be called in all failure case
after mem_cgroup_charge_newpage() is called in 
huge_memory.c::collapse_huge_page()

I hope this is the last time we'd see the bad_page for memcg ;)

Yes, the rest of the info on the page looked ok and shouldn't have
triggered a bad_page call. Thanks so much for looking into it.

There is a separate little issue here, Andrea.

Although we went to some trouble for bad_page() to take the page out
of circulation yet let the system continue, your VM_BUG_ON(!PageBuddy)
inside __ClearPageBuddy(page), from two callsites in bad_page(), is
turning it into a fatal error when CONFIG_DEBUG_VM.

You could that only MM developers switch CONFIG_DEBUG_VM=y, and they
would like bad_page() to be fatal; maybe, but if so we should do that
as an intentional patch, rather than as an unexpected side-effect ;)

I noticed this a few days ago, but hadn't quite decided whether just to
remove the VM_BUG_ON, or move it to __ClearPageBuddy's third callsite,
or... doesn't matter much.

I do also wonder if PageBuddy would better be _mapcount -something else:
if we've got a miscounted page (itself unlikely of course), there's a
chance that its _mapcount will be further decremented after it has been
freed: whereupon it will go from -1 to -2, PageBuddy at present.  The
special avoidance of PageBuddy being that it can pull a whole block of
pages into misuse if its mistaken.

I see what you mean. Of course it is only a problem after bad_page
already triggered.... but then it trigger an BUG_ON instead of only a
bad_page.

Fedora kernels are built with CONFIG_DEBUG_VM, all my kernels runs
with CONFIG_DEBUG_VM too, so we want it to be as "production" as
possible, and we don't want DEBUG_VM to decrease any reliability (only
to increase it of course).

Agreed. What about the below?

=====
Subject: mm: PageBuddy cleanups

From: Andrea Arcangeli <aarcange@redhat.com>

bad_page could VM_BUG_ON(!PageBuddy(page)) inside __ClearPageBuddy(). I prefer
to keep the VM_BUG_ON for safety and to add a if to solve it.

Change the _mapcount value indicating PageBuddy from -2 to -1024 for more
robusteness against page_mapcount() undeflows.

Oh, I hadn't realized Fedora use it.  I wonder if that's wise, I thought
Nick introduced it partly for the more expensive checks, and there might
be one or two of those around - those bad_range()s in page_alloc.c?

Too much iffery: I ended up preferring it in rmv_page_order() myself.

But the patch actually says -1024*1024: either would do.

Yes, good to comment that, thanks.

Yes, that's fine, 0xfff00000 looks unlikely enough (and my
imagination for "deadbeef"-like magic is too drowsy today).

Okay I suppose: it seems rather laboured to me, I think I'd have just
moved the VM_BUG_ON into rmv_page_order() if I'd done the patch; but
since I was too lazy to do it, I'd better be grateful for yours!

I doubt the more expensive checks are very measurable.. benchmarks
usually run on enterprise distro. I'm sure when they enabled, they
were aware of having to run more expensive runtime checks.

I actually increased it to -1024*1024 after writing the email ;) sorry
the for the confusion.

I used a negative power of two even if I doubt the compiler can make
much use of it.

Ok the reason I didn't move the VM_BUG_ON is to be stricter in case
there are more usages of __ClearPageBuddy in the future. I guess it's
not so important, but when I initially implemented it, it wasn't
entirely obvious it would work safe with memory hotplug, compaction
and all other bits using PageBuddy, so...

Are you sure?

$ grep DEBUG_VM /boot/config-*
/boot/config-2.6.35.10-74.fc14.x86_64:# CONFIG_DEBUG_VM is not set
/boot/config-2.6.35.6-45.fc14.x86_64:# CONFIG_DEBUG_VM is not set

Only the one from the kernel-debug package has it set on this F14.
