mm: BUG in unmap_page_range

Hi all,

While fuzzing with trinity inside a KVM tools guest running the latest -next kernel, I've stumbled on the following spew:

This differs in which functions got inlined (unmap_page_range showing up in place of zap_pte_range), but this is the same "if (PageAnon(page))" that Sasha reported in the "hang in shmem_fallocate" thread on June 26th.

I can see what it is now, and here is most of a patch (which I don't expect to satisfy Trinity yet); at this point I think I had better hand it over to Mel, to complete or to discard.

[INCOMPLETE PATCH] x86,mm: fix pte_special versus pte_numa

Sasha Levin has shown oopses on ffffea0003480048 and ffffea0003480008 at mm/memory.c:1132, running Trinity on different 3.16-rc-next kernels:
where zap_pte_range() checks page->mapping to see if PageAnon(page).

Those addresses fit struct pages for pfns d2001 and d2000, and in each dump a register or a stack slot showed d2001730 or d2000730: pte flags 0x730 are PCD ACCESSED PROTNONE SPECIAL IOMAP; and Sasha's e820 map has a hole between cfffffff and 100000000, which would need special access.

Commit c46a7c817e66 ("x86: define _PAGE_NUMA by reusing software bits on the PMD and PTE levels") has broken vm_normal_page(): a PROTNONE SPECIAL pte no longer passes the pte_special() test, so zap_pte_range() goes on to try to access a non-existent struct page.

Fix this by refining pte_special() (SPECIAL with PRESENT or PROTNONE) to complement pte_numa() (SPECIAL with neither PRESENT nor PROTNONE).

It's unclear why c46a7c817e66 added pte_numa() test to vm_normal_page(), and moved its is_zero_pfn() test from slow to fast path: I suspect both were papering over PROT_NONE issues seen with inadequate pte_special(). Revert vm_normal_page() to how it was before, relying on pte_special().

I find it confusing, that the only example of ARCH_USES_NUMA_PROT_NONE no longer uses PROTNONE for NUMA, but SPECIAL instead: update the asm-generic comment a little, but that config option remains unhelpful.

But more seriously, I think this patch is incomplete: aren't there other places which need to be handling PROTNONE along with PRESENT? For example, pte_mknuma() clears _PAGE_PRESENT and sets _PAGE_NUMA, but on a PROT_NONE area, I think that will now make it pte_special()? So it ought to clear _PAGE_PROTNONE too. Or maybe we can never pte_mknuma() on a PROT_NONE area - there would be no point?

Around here I began to wonder if it was just a mistake to have deserted the PROTNONE for NUMA model: I know Linus had a strong reaction against it, and I've never delved into its drawbacks myself; but bringing yet another (SPECIAL) flag into the game is not an obvious improvement. Should we just revert c46a7c817e66, or would that be a mistake?

Let me hand this over to Mel now...

Rather than answering directly I updated your changelog

Fix this by refining pte_special() (SPECIAL with PRESENT or PROTNONE) to complement pte_numa() (SPECIAL with neither PRESENT nor PROTNONE).

A hint that this was a problem was that c46a7c817e66 added pte_numa() test to vm_normal_page(), and moved its is_zero_pfn() test from slow to fast path: This was papering over a pte_special() snag when the zero page was encountered during zap. This patch reverts vm_normal_page() to how it was before, relying on pte_special().

ARCH_USES_NUMA_PROT_NONE should have been sent to the farm at the same time as that patch and by rights unified with the powerpc helpers. With the new _PAGE_NUMA bit, there is no reason they should have different implementations of pte_numa and related functions. Unfortunately unifying them is a little problematic due to differences in fundamental types. It could be done with #defines but I'm attaching a preliminary prototype to illustrate the issue.

We are depending on the fact that inaccessible VMAs are skipped by the NUMA hinting scanner.

It's replacing one type of complexity with another. The downside is that _PAGE_NUMA == _PAGE_PROTNONE puts subtle traps all over the core for powerpc to fall foul of.

I'm attaching a preliminary pair of patches. The first which deals with ARCH_USES_NUMA_PROT_NONE and the second which is yours with a revised changelog. I'm adding Aneesh to the cc to look at the powerpc portion of the first patch.

Subject: [PATCH] mm: Remove misleading ARCH_USES_NUMA_PROT_NONE

ARCH_USES_NUMA_PROT_NONE was defined for architectures that implemented _PAGE_NUMA using _PROT_NONE. This saved using an additional PTE bit and relied on the fact that PROT_NONE vmas were skipped by the NUMA hinting fault scanner. This was found to be conceptually confusing with a lot of implicit assumptions and it was asked that an alternative be found.

Commit c46a7c81 "x86: define _PAGE_NUMA by reusing software bits on the PMD and PTE levels" redefined _PAGE_NUMA on x86 to be one of the swap PTE bits and shrunk the maximum possible swap size but it did not go far enough. There are no architectures that reuse _PROT_NONE as _PROT_NUMA but the relics still exist.

This patch removes ARCH_USES_NUMA_PROT_NONE and removes some unnecessary duplication in powerpc vs the generic implementation by defining the types the core NUMA helpers expected to exist from x86 with their ppc64 equivalent. The unification for ppc64 is less than ideal because types do not exist that the "generic" code expects to. This patch works around the problem but it would be preferred if the powerpc people would look at this to see if they have opinions on what might suit them better.

Subject: [PATCH] x86,mm: fix pte_special versus pte_numa

Sasha Levin has shown oopses on ffffea0003480048 and ffffea0003480008 at mm/memory.c:1132, running Trinity on different 3.16-rc-next kernels:
where zap_pte_range() checks page->mapping to see if PageAnon(page).

Those addresses fit struct pages for pfns d2001 and d2000, and in each dump a register or a stack slot showed d2001730 or d2000730: pte flags 0x730 are PCD ACCESSED PROTNONE SPECIAL IOMAP; and Sasha's e820 map has a hole between cfffffff and 100000000, which would need special access.

Commit c46a7c817e66 ("x86: define _PAGE_NUMA by reusing software bits on the PMD and PTE levels") has broken vm_normal_page(): a PROTNONE SPECIAL pte no longer passes the pte_special() test, so zap_pte_range() goes on to try to access a non-existent struct page.

Fix this by refining pte_special() (SPECIAL with PRESENT or PROTNONE) to complement pte_numa() (SPECIAL with neither PRESENT nor PROTNONE). A hint that this was a problem was that c46a7c817e66 added pte_numa() test to vm_normal_page(), and moved its is_zero_pfn() test from slow to fast path: This was papering over a pte_special() snag when the zero page was encountered during zap. This patch reverts vm_normal_page() to how it was before, relying on pte_special().

It still appears that this patch may be incomplete: aren't there other places which need to be handling PROTNONE along with PRESENT? For example, pte_mknuma() clears _PAGE_PRESENT and sets _PAGE_NUMA, but on a PROT_NONE area, that would make it it pte_special(). This is side-stepped by the fact that NUMA hinting faults skiped PROT_NONE VMAs and there are no grounds where a NUMA hinting fault on a PROT_NONE VMA would be interesting.

Partially-Fixes: c46a7c817e66 ("x86: define _PAGE_NUMA by reusing software bits on the PMD and PTE levels")

Thanks, that's fine.

Ah, okay. And the other way round (mprotecting to PROT_NONE an area which already contains _PAGE_NUMA ptes) already looked safe to me.

Okay.

Thanks a lot, Mel.

I am surprised by the ordering, but perhaps you meant nothing by it. Isn't the first one a welcome but optional cleanup, and the second one a fix that we need in 3.16-stable? Or does the fix actually depend in some unstated way upon the cleanup, in powerpc-land perhaps?

Aside from that, for the first patch: yes, I heartily approve of the disappearance of CONFIG_ARCH_WANTS_PROT_NUMA_PROT_NONE and CONFIG_ARCH_USES_NUMA_PROT_NONE. If you wish, add

but of course it's really Aneesh and powerpc who are the test of it.

One thing I did wonder, though: at first I was reassured by the VM_BUG_ON(!pte_present(pte)) you add to pte_mknuma(); but then thought it would be better as VM_BUG_ON(!(val & _PAGE_PRESENT)), being stronger
- asserting that indeed we do not put NUMA hints on PROT_NONE areas. (But I have not tested, perhaps such a VM_BUG_ON would actually fire.)

And in the second patch, a few trivial edits:

s/it it/it/

s/skiped/skip/

s/Partially-//

s/Not-yet-//

Ditto I must leave to you!

Thanks Hugh, Mel. I've added both patches to my local tree and will update tomorrow with the weather.

Also:

I've added VM_BUG_ON(!(val & _PAGE_PRESENT)) in just as a curiosity, I'll update how that one looks as well.

Thanks,
Sasha

Sorry for the rather long delay.

The patch looks fine, the issue didn't reproduce.

The added VM_BUG_ON didn't trigger either, so maybe we should consider adding it in.

Thanks,
Sasha

ARCH_USES_NUMA_PROT_NONE was defined for architectures that implemented _PAGE_NUMA using _PROT_NONE. This saved using an additional PTE bit and relied on the fact that PROT_NONE vmas were skipped by the NUMA hinting fault scanner. This was found to be conceptually confusing with a lot of implicit assumptions and it was asked that an alternative be found.

Commit c46a7c81 "x86: define _PAGE_NUMA by reusing software bits on the PMD and PTE levels" redefined _PAGE_NUMA on x86 to be one of the swap PTE bits and shrunk the maximum possible swap size but it did not go far enough. There are no architectures that reuse _PROT_NONE as _PROT_NUMA but the relics still exist.

This patch removes ARCH_USES_NUMA_PROT_NONE and removes some unnecessary duplication in powerpc vs the generic implementation by defining the types the core NUMA helpers expected to exist from x86 with their ppc64 equivalent. This necessitated that a PTE bit mask be created that identified the bits that distinguish present from NUMA pte entries but it is expected this will only differ between arches based on _PAGE_PROTNONE. The naming for the generic helpers was taken from x86 originally but ppc64 has types that are equivalent for the purposes of the helper so they are mapped instead of duplicating code.

The tests to reach here are

pte_present     any of  _PAGE_PRESENT | _PAGE_PROTNONE | _PAGE_NUMA
pte_numa        only    _PAGE_NUMA out of _PAGE_PRESENT | _PAGE_PROTNONE | _PAGE_NUMA

VM_BUG_ON not set _PAGE_PRESENT

To trigger the bug the PTE bits must then be _PAGE_PROTNONE | _PAGE_NUMA. The NUMA PTE scanner is skipping PROT_NONE VMAs so it should be "impossible" for it to be set there. The mmap_sem is held for read during scans so the protections should not be altering underneath us and the PTL is held against parallel faults.

That leaves setting prot_none leaveing _PAGE_NUMA behind. Potentially that's an issue due to

/* Set of bits not changed in pte_modify */
#define _PAGE_CHG_MASK (PTE_PFN_MASK | _PAGE_PCD | _PAGE_PWT | \
_PAGE_SPECIAL | _PAGE_ACCESSED | _PAGE_DIRTY | \
_PAGE_SOFT_DIRTY | _PAGE_NUMA)

The _PAGE_NUMA bit is not cleared as removing it potentially leaves the PTE in an unexpected state due to a "present" PTE marked for NUMA hinting fault becoming non-present. Instead there is this check in change_pte_range() to move PTEs to a known state before changing protections

                                if (pte_numa(ptent))
                                        ptent = pte_mknonnuma(ptent);
                                ptent = pte_modify(ptent, newprot);

So right now, I'm not seeing what path gets us to this inconsistent state. Sasha, how long does it typically take to trigger this? Are you using any particular switches for trinity that would trigger the bug faster?

This untested patch might help pinpoint the source of the corruption early though it's x86 only

It took couple of weeks (I've been running with it since the beginning of August). I don't have any special trinity options, just the default fuzzing. Do you think that focusing on any of the mm syscalls would increase the odds of hitting it?

There's always the chance that this is a fluke due to corruption somewhere else. I'll keep running it with the new debug patch and if it won't reproduce any time soon we can probably safely assume that.

Thanks,
Sasha

Okay, this bug has reproduced quite a few times since then that I no longer suspect it's random memory corruption. I'd be happy to try out more debug patches if you have any leads.

Thanks,
Sasha

The fact the second one doesn't trigger makes me think that this is not related to how the helpers are called and is instead relating to timing. I tried reproducing this but got nothing after 3 hours. How long does it typically take to reproduce in a given run? You mentioned that it takes a few weeks to hit but maybe the frequency has changed since. I tried todays linux-next kernel but it didn't even boot so next-20140826 to match your original report but got nothing. Can you also send me the config you used in case that's a factor.

I had one hunch that this may somehow be related to a collision between pagetable teardown during exit and the scanner but I could not find a way that could actually happen. During teardown there should be only one user of the mm and it can't race with itself.

A worse possibility is that somehow the lock is getting corrupted but that's also a tough sell considering that the locks should be allocated from a dedicated cache. I guess I could try breaking that to allocate one page per lock so DEBUG_PAGEALLOC triggers but I'm not very optimistic.

The frequency seems to have changed, I can trigger this 5-10 times a day now.

Config is attached.
