but the system has plenty droppable cache.

Umm, Is this reproducable?
Typically such strange log was caused by corruptted ram. can you please
check your memory correctness?

I think this problem results from 'gfp_mask = 0x0'.
Is it possible?

If it isn't H/W problem, Who passes gfp_mask with 0x0?
It's culpit. 

Could you add BUG_ON(gfp_mask == 0x0) in __alloc_pages_nodemask's head?

                        struct zonelist *zonelist, nodemask_t *nodemask)
{
        enum zone_type high_zoneidx = gfp_zone(gfp_mask);

Maybe some code returns VM_FAULT_OOM by mistake and pagefault_oom_killer()
is called. digging mm/memory.c is necessary...

I wonder why...now is this code
===
static int do_nonlinear_fault(struct mm_struct *mm, struct vm_area_struct *vma,
                unsigned long address, pte_t *page_table, pmd_t *pmd,
                unsigned int flags, pte_t orig_pte)
{
        pgoff_t pgoff;

        flags |= FAULT_FLAG_NONLINEAR;

	if (!pte_unmap_same(mm, pmd, page_table, orig_pte))
                return 0;

        if (unlikely(!(vma->vm_flags & VM_NONLINEAR))) {
                /*
                 * Page table corrupted: show pte and kill process.
                 */
                print_bad_pte(vma, address, orig_pte, NULL);
                return VM_FAULT_OOM;
        }

        pgoff = pte_to_pgoff(orig_pte);
        return __do_fault(mm, vma, address, pmd, pgoff, flags, orig_pte);
}
==
Then, OOM...is this really OOM ?

Thanks,

It seems that the goal is to kill process by OOM trick as comment said.

I found It results from Hugh's commit 65500d234e74fc4e8f18e1a429bc24e51e75de4a.
I think it's not a real OOM. 

BTW, If it is culpit in this case, print_bad_pte should have remained any log. :)

Yes, the chances are that this is not related to Norbert's problem.
But thank you for reminding me of that not-very-nice hack of mine.

It was kind-of valid at the time that I wrote it (2.6.15), when
VM_FAULT_OOM did kill the faulting process.  But since then the fault
path has rightly been changed (in x86 at least, I didn't check the rest)
to let the OOM killer decide who to kill: so now there's a danger that
a pagetable corruption there will instead kill some unrelated process.

Being lazy, I'm inclined simply to change that to VM_FAULT_SIGBUS now:
which doesn't actually guarantee that the process will be killed, but
should be better than just repeatedly re-faulting on the entry.  (I
don't much want to SIGKILL current since mm might not be current's.)

That aberrant use of VM_FAULT_OOM has recently been copied into
do_swap_page() (the first instance; the second instance is right -
hmm, well, the second instance is normally right, but I guess it
also covers pagetable corruption cases which we can't distinguish
there; oh well) and should be corrected there too.

Does VM_FAULT_SIGBUS sound good enough to you?

I am Okay. 
First of all, we have to prevent innocent process killing.
Second, although it returns SIGBUS, we can distinguish it from normal SIGBUS
by bad pte log.
Third, we don't want to add new VM_FAULT_XXX as possible as. :)

I suspect GPU drivers related to X.
It seems many of them returs VM_FAULT_OOM.

If it happens by file map fault, following debug patch can show the culpit.

Norbert, Could you apply this patch and test again?
If you can get the address, you can find function symbol with System.map.

Re: OOM killer, page fault

Hi all,

wow, many messages ... At the end I lost track of which patch I should try?

BTW, that happened only once, and whatever I do I cannot reproduce that.

I will anyway include any patch you send me and hope that it happens again.

Thanks

Re: OOM killer, page fault

[Norbert Preining]

Hi Kim, hi all,

(still please Cc)

sorry for the late reply. I have two news, one good and one bad: The good
being that I can reproduce the bug by running VirtualBox with some W7
within. Anyway, I don't have a trace or better debug due to the bad news:
Both 2.6.32-rc5 and 2.6.32-rc6 do *not* boot with the patch below.
Don't ask me why, please, and I don't have a serial/net console so that
I can tell you more, but the booting hangs badly at:
[    6.657492] usb 4-1: Product: Globetrotter HSDPA Modem

[    6.853693] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio2/input/input7

Normally it continues like that, but with the patch below it hangs here
and does not continue. I need to Sysrq-s/u/b out of it.

I know it sounds completely crazy, the patch only does harmless things
afais. But I tried it. Several times. rc6+patch never did boot, while
rc5 without path did boot. Then I patched it into -rc5, recompiled, and 
boom, no boot. booting into .31.5, recompiling rc6 and rc5 without 
that patch and suddenly rc6 boots (and I am sure rc5, too).

Sorry that I cannot give more infos, please let me know what else I can
do.

Ah yes, I can reproduce the original strange bug with oom killer!

Best wishes

Norbert

Hmm. It's out of my knowledge.
Probably, It's because WARN_ON?
Could you try it with omitting WARN_ON, again?

Thanks for your time :)

Sounds good to me.
Could you tell me your test scenario, your system info(CPU, RAM) and
config?
I want to reproduce it in my mahchine to not bother you. :)

Puhh, well, I meant "I could reproduce it", but not "I have a clear
idea what steps to be taken to reproduce it" ;-) Well here is what I can
tell you:
actual hardware:
Intel(R) Core(TM)2 Duo CPU     P9500
Memory 2G
Config of my kernel attached.

Virtual Machine (VirtualBox, not the OSE variant, I need USB 2.0 support
for GPS stuff):
VirtualBox 3.0.10
memory for the machine: 1G (50%)
ACPI and IO/APIC turned on
1 processor with PAE/NX
VT-x and Nested Paging activated
Display 128M
(need more details?)

I will remove the WARN_ON and reboot and see if that works. If yes I try
to recreate the problem.

Best wishes

Norbert

No change, still hangs. But at least I see now that it is not hanging
at an arbitrary position, but it does not start the init process. It
stops right before the "Calling init" or similar-

BTW, this time the config is really attached.

Erm, could it not be due to the "return ret;" line being moved outside of the
if(), so that it always executes?

Right. Sorry it's my fault.
I become  blind.
'return ret' should be inclueded in debug code.

Bummer, I'm blind, too, that was in fact obvious, since the codeflow
was changed. Could have seen that myself, sorry.

Recompiling already and trying to recreate the oom-killer boom.

Well, after rebooting into that kernel I get *loads*, every few seconds,

I guess it is VM_FAULT_NOPAGE of i915_gem or somethings.
It's not of our concern but VM_FAULT_OOM.
I couldn't expect that. So let's change debug patch following as.

Most important thing is "Who return VM_FAULT_OOM".
It it return VM_FAULT_OOM, OOM killer will kill any process who have a
high score. In case of you, it was 'X'.

If you don't see it until 2.6.32-rc5, It should be regression in somewhere.
If we can know it, we can pass the problem to maintainer of it.

Could you try it again below patch?
If you reproduce it, you can match function address of log with
function address
of your System.map. Pz, let me know it. :)

No.
In page fault case, gfp_mask show meaningless value. Please ignore it.
pagefault_out_of_memory() always pass gfp_mask==0 to oom.
