[PATCH V2 0/3] mm/debug: Add more arch page table helper tests

[Anshuman Khandual]

This series adds more arch page table helper tests. The new tests here are
either related to core memory functions and advanced arch pgtable helpers.
This also creates a documentation file enlisting all expected semantics as
suggested by Mike Rapoport (https://lkml.org/lkml/2020/1/30/40).

This series has been tested on arm64 and x86 platforms. There is just one
expected failure on arm64 that will be fixed when we enable THP migration.

[   21.741634] WARNING: CPU: 0 PID: 1 at mm/debug_vm_pgtable.c:782

which corresponds to

WARN_ON(!pmd_present(pmd_mknotpresent(pmd_mkhuge(pmd))))

There are many TRANSPARENT_HUGEPAGE and ARCH_HAS_TRANSPARENT_HUGEPAGE_PUD
ifdefs scattered across the test. But consolidating all the fallback stubs
is not very straight forward because ARCH_HAS_TRANSPARENT_HUGEPAGE_PUD is
not explicitly dependent on ARCH_HAS_TRANSPARENT_HUGEPAGE.

This series has been build tested on many platforms including the ones that
subscribe the test through ARCH_HAS_DEBUG_VM_PGTABLE.

This series is based on v5.6-rc7 after applying these following patches.

1. https://patchwork.kernel.org/patch/11431277/
2. https://patchwork.kernel.org/patch/11452185/

Changes in V2:

- Dropped CONFIG_ARCH_HAS_PTE_SPECIAL per Christophe
- Dropped CONFIG_NUMA_BALANCING per Christophe
- Dropped CONFIG_HAVE_ARCH_SOFT_DIRTY per Christophe
- Dropped CONFIG_MIGRATION per Christophe
- Replaced CONFIG_S390 with __HAVE_ARCH_PMDP_INVALIDATE
- Moved page allocation & free inside swap_migration_tests() per Christophe
- Added CONFIG_TRANSPARENT_HUGEPAGE to protect pfn_pmd()
- Added CONFIG_HAVE_ARCH_TRANSPARENT_HUGEPAGE_PUD to protect pfn_pud()
- Added a patch for other arch advanced page table helper tests
- Added a patch creating a documentation for page table helper semantics

[PATCH V2 1/3] mm/debug: Add tests validating arch page table helpers for core features

[Anshuman Khandual]

This adds new tests validating arch page table helpers for these following
core memory features. These tests create and test specific mapping types at
various page table levels.

1. SPECIAL mapping
2. PROTNONE mapping
3. DEVMAP mapping
4. SOFTDIRTY mapping
5. SWAP mapping
6. MIGRATION mapping
7. HUGETLB mapping
8. THP mapping

[PATCH V2 2/3] mm/debug: Add tests validating arch advanced page table helpers

[Anshuman Khandual]

This adds new tests validating for these following arch advanced page table
helpers. These tests create and test specific mapping types at various page
table levels.

1. pxxp_set_wrprotect()
2. pxxp_get_and_clear()
3. pxxp_set_access_flags()
4. pxxp_get_and_clear_full()
5. pxxp_test_and_clear_young()
6. pxx_leaf()
7. pxx_set_huge()
8. pxx_(clear|mk)_savedwrite()

I think we need a better comment here, because requiring pmd_trans_huge() and
pmd_present() returning true after pmd_mknotpresent() is not straightforward.

According to Andrea Arcangeli’s email (https://lore.kernel.org/linux-mm/20181017020930.GN30832@redhat.com/),
This behavior is an optimization for transparent huge page.
pmd_trans_huge() must be true if pmd_page() returns you a valid THP to avoid
taking the pmd_lock when others walk over non transhuge pmds (i.e. there are no
THP allocated). Especially when we split a THP, removing the present bit from
the pmd, pmd_trans_huge() still needs to return true. pmd_present() should
be true whenever pmd_trans_huge() returns true.

I think it is also worth either putting Andres’s email or the link to it
in the rst file in your 3rd patch. It is a good documentation for this special
case.

Sure, will modify the existing comment here like this.

	/*

Makes sense. Will update Andrea's email link in the .rst file as well.

If folks can test these patches out on remaining ARCH_HAS_DEBUG_VM_PGTABLE
enabled platforms i.e s390, arc, powerpc (32 and 64), that will be really
appreciated. Thank you.

Both set of definitions suggest that the last three bits (if present)
on the PTE will be discarded during PTE->SWP->PTE conversion which
might be leading to this mismatch and subsequent failure.

arch/powerpc/include/asm/nohash/32/pgtable.h
arch/powerpc/include/asm/book3s/32/pgtable.h

#define __pte_to_swp_entry(pte)         ((swp_entry_t) { pte_val(pte) >> 3 })
#define __swp_entry_to_pte(x)           ((pte_t) { (x).val << 3 })

Also there are some more architectures (microblaze, sh, etc) where these
conversions are not always preserving. On powerpc64, it sets back _PAGE_PTE
irrespective of whether the bit was originally set or not.

Probably it is wrong to expect that PTE->SWP->PTE conversion will be always
preserving. So wondering if it is worth changing this test to accommodate
all such architectures or just drop it instead.

Hi Anshuman,

thanks for the update. There are a couple of issues on s390, some might
also affect other archs.

1) The pxd_huge_tests are using pxd_set/clear_huge, which defaults to
returning 0 if !CONFIG_HAVE_ARCH_HUGE_VMAP. As result, the checks for
!pxd_test/clear_huge in the pxd_huge_tests will always trigger the
warning. This should affect all archs w/o CONFIG_HAVE_ARCH_HUGE_VMAP.
Could be fixed like this:

BTW, please add some comments to the various #ifdef/#else stuff, especially
when the different parts are far away and/or nested.

2) The hugetlb_advanced_test will fail because it directly de-references
huge *ptep pointers instead of using huge_ptep_get() for this. We have
very different pagetable entry layout for pte and (large) pmd on s390,
and unfortunately the whole hugetlbfs code is using pte_t instead of pmd_t
like THP. For this reason, huge_ptep_get() was introduced, which will
return a "converted" pte, because directly reading from a *ptep (pointing
to a large pmd) will not return a proper pte. Only ARM has also an
implementation of huge_ptep_get(), so they could be affected, depending
on what exactly they need it for.

Could be fixed like this (the first de-reference is a bit special,
because at that point *ptep does not really point to a large (pmd) entry
yet, it is initially an invalid pte entry, which breaks our huge_ptep_get()
conversion logic. I also added PMD_MASK alignment for RANDOM_ORVALUE,
because we do have some special bits there in our large pmds. It seems
to also work w/o that alignment, but it feels a bit wrong):

3) The pmd_protnone_tests() has an issue, because it passes a pmd to
pmd_protnone() which has not been marked as large. We check for large
pmd in the s390 implementation of pmd_protnone(), and will fail if a
pmd is not large. We had similar issues before, in other helpers, where
I changed the logic on s390 to not require the pmd large check, but I'm
not so sure in this case. Is there a valid use case for doing
pmd_protnone() on "normal" pmds? Or could this be changed like this:

Sure, thanks for taking a look and giving it a spin on s390.

That is correct. It was an omission on my part and will fix it.

Currently, we dont support ARM (32). But as huge_ptep_get() already got a
fallback, its better to use that than a direct READ_ONCE().

There seems to be an inconsistency on s390 platform. Even though it defines
a huge_ptep_get() override, it does not subscribe __HAVE_ARCH_HUGE_PTEP_GET
which should have forced it fallback on generic huge_ptep_get() but it does
not :) Then I realized that __HAVE_ARCH_HUGE_PTEP_GET only makes sense when
an arch uses <asm-generic/hugetlb.h>. s390 does not use that and hence gets
away with it's own huge_ptep_get() without __HAVE_ARCH_HUGE_PTEP_GET. Sounds
confusing ? But I might not have the entire context here.

Sure, we can accommodate that.

So that keeps the existing value in 'ptep' pointer at bay and instead
construct a PTE from scratch. I would rather have READ_ONCE(*ptep) at
least provide the seed that can be ORed with RANDOM_ORVALUE before
being masked with PMD_MASK. Do you see any problem ?

Some thing like this instead.

pte_t pte = READ_ONCE(*ptep);
pte = pte_mkhuge(__pte((pte_val(pte) | RANDOM_ORVALUE) & PMD_MASK));

We cannot use mk_pte_phys() as it is defined only on some platforms
without any generic fallback for others.

That is a valid question. IIUC, all existing callers for pmd_protnone()
ensure that it is indeed a huge PMD. But even assuming otherwise should
not the huge PMD requirement get checked in the caller itself rather than
in the arch helper which is just supposed to check the existence of the
dedicated PTE bit(s) for this purpose. Purely from a helper perspective
pmd_protnone() should not really care about being large even though it
might never get used without one.

Also all platforms (except s390) derive the pmd_protnone() from their
respective pte_protnone(). I wonder why should s390 be any different
unless it is absolutely necessary.

Yes, that sounds very confusing. Also a bit ironic, since huge_ptep_get()
was initially introduced because of s390, and now we don't select
__HAVE_ARCH_HUGE_PTEP_GET...

As you realized, I guess this is because we do not use generic hugetlb.h.
And when __HAVE_ARCH_HUGE_PTEP_GET was introduced with commit 544db7597ad
("hugetlb: introduce generic version of huge_ptep_get"), that was probably
the reason why we did not get our share of __HAVE_ARCH_HUGE_PTEP_GET.

Nothing really wrong with that, but yes, very confusing. Maybe we could
also select it for s390, even though it wouldn't have any functional
impact (so far), just for less confusion. Maybe also thinking about
using the generic hugetlb.h, not sure if the original reasons for not
doing so would still apply. Now I only need to find the time...

Yes, unfortunately. The problem is that the resulting pte is not marked
as present. The conversion pte -> (huge) pmd, which is done in
set_huge_pte_at() for s390, will establish an empty pmd for non-present
ptes, all the RANDOM_ORVALUE stuff is lost. And a subsequent
huge_ptep_get() will not result in the same original pte value. If you
want to preserve and check the RANDOM_ORVALUE, it has to be a present
pte, hence the mk_pte(_phys).

Oh, didn't know that, sorry. What about using mk_pte() instead, at least
it would result in a present pte:

pte = pte_mkhuge(mk_pte(phys_to_page(RANDOM_ORVALUE & PMD_MASK), prot));

And if you also want to do some with the existing value, which seems
to be an empty pte, then maybe just check if writing and reading that
value with set_huge_pte_at() / huge_ptep_get() returns the same,
i.e. initially w/o RANDOM_ORVALUE.

So, in combination, like this (BTW, why is the barrier() needed, it
is not used for the other set_huge_pte_at() calls later?):

This would actually add a new test "write empty pte with
set_huge_pte_at(), then verify with huge_ptep_get()", which happens
to trigger a warning on s390 :-)

That (new) warning actually points to misbehavior on s390, we do not
write a correct empty pmd in this case, but one that is empty and also
marked as large. huge_ptep_get() will then not correctly recognize it
as empty and do wrong conversion. It is also not consistent with
huge_ptep_get_and_clear(), where we write the empty pmd w/o marking
as large. Last but not least it would also break our pmd_protnone()
logic (see below). Another nice finding on s390 :-)

I don't think this has any effect in practice (yet), but I will post a
fix for that, just in case you will add / change this test.

This is again because of our different page table entry layouts for
pte/pmd and (large) pmd. The bits we check for pmd_protnone() are
not valid for normal pmd/pte, and we would return undefined result for
normal entries.

Of course, we could rely on nobody calling pmd_protnone() on normal
pmds, but in this case we also use pmd_large() check in pmd_protnone()
for indication if the pmd is present. W/o that, we would return
true for empty pmds, that doesn't sound right. Not sure if we also
want to rely on nobody calling pmd_protnone() on empty pmds.

Anyway, if in practice it is not correct to use pmd_protnone()
on normal pmds, then I would suggest that your tests should also
not do / test it. And I strongly assume that it is not correct, at
least I cannot think of a valid case, and of course s390 would
already be broken if there was such a case.

Gerald

Lets use mk_pte() here but can we do this instead

paddr = (__pfn_to_phys(pfn) | RANDOM_ORVALUE) & PMD_MASK;
pte = pte_mkhuge(mk_pte(phys_to_page(paddr), prot));

Ahh missed, will add them. Earlier we faced problem without it after
set_pte_at() for a test on powerpc (64) platform. Hence just added it
here to be extra careful.

On arm64 as well which checks for pte_present() in set_huge_pte_at().
But PTE present check is not really present in each set_huge_pte_at()
implementation especially without __HAVE_ARCH_HUGE_SET_HUGE_PTE_AT.
Hence wondering if we should add this new test here which will keep
giving warnings on s390 and arm64 (at the least).

Okay, will use huge PMD here as you had suggested earlier.

Sure, that will also work.

BTW, this RANDOM_ORVALUE is not really very random, the way it is
defined. For s390 we already changed it to mask out some arch bits,
but I guess there are other archs and bits that would always be
set with this "not so random" value, and I wonder if/how that would
affect all the tests using this value, see also below.

Hmm, interesting. I forgot about huge swap / migration, which is not
(and probably cannot be) supported on s390. The pte_present() check
on arm64 seems to check for such huge swap / migration entries,
according to the comment.

The new test "write empty pte with set_huge_pte_at(), then verify
with huge_ptep_get()" would then probably trigger the
WARN_ON(!pte_present(pte)) in arm64 code. So I guess "writing empty
ptes with set_huge_pte_at()" is not really a valid use case in practice,
or else you would have seen this warning before. In that case, it
might not be a good idea to add this test.

I also do wonder now, why the original test with
"pte = __pte(pte_val(pte) | RANDOM_ORVALUE);"
did not also trigger that warning on arm64. On s390 this test failed
exactly because the constructed pte was not present (initially empty,
or'ing RANDOM_ORVALUE does not make it present for s390). I guess this
just worked by chance on arm64, because the bits from RANDOM_ORVALUE
also happened to mark the pte present for arm64.

This brings us back to the question above, regarding the "randomness"
of RANDOM_ORVALUE. Not really sure what the intention behind that was,
but maybe it would make sense to restrict this RANDOM_ORVALUE to
non-arch-specific bits, i.e. only bits that would be part of the
address value within a page table entry? Or was it intentionally
chosen to also mess with other bits?

Regards,
Gerald

RANDOM_ORVALUE is a constant which was added in order to make sure
that the page table entries should have some non-zero value before
getting called with pxx_clear() and followed by a pxx_none() check.
This is currently used only in pxx_clear_tests() tests. Hence there
is no impact for the existing tests.

Got it.

That is correct. RANDOM_ORVALUE has got PTE_PROT_NONE bit set that makes
the PTE test for pte_present().

On arm64 platform,

#define pte_present(pte)  (!!(pte_val(pte) & (PTE_VALID | PTE_PROT_NONE)))

As mentioned before, RANDOM_ORVALUE just helped make a given page table
entry contain non-zero values before getting cleared. AFAICS we should
not need RANDOM_ORVALUE for HugeTLB test here. I believe the following
'paddr' construct will just be fine instead.

paddr = __pfn_to_phys(pfn) & PMD_MASK;
pte = pte_mkhuge(mk_pte(phys_to_page(paddr), prot));
