[PATCH v1 0/3] Improve hugetlbfs read on HWPOISON hugepages

[PATCH v1 0/3] Improve hugetlbfs read on HWPOISON hugepages

[Jiaqi Yan]

Today when hardware memory is corrupted in a hugetlb hugepage,
kernel leaves the hugepage in pagecache [1]; otherwise future mmap or
read will suject to silent data corruption. This is implemented by
returning -EIO from hugetlb_read_iter immediately if the hugepage has
HWPOISON flag set.

Since memory_failure already tracks the raw HWPOISON subpages in a
hugepage, a natural improvement is possible: if userspace only asks for
healthy subpages in the pagecache, kernel can return these data.

This patchset implements this improvement. It consist of three parts.
The 1st commit exports the functionality to tell if a subpage inside a
hugetlb hugepage is a raw HWPOISON page. The 2nd commit teaches
hugetlbfs_read_iter to return as many healthy bytes as possible.
The 3rd commit properly tests this new feature.

[PATCH v1 1/3] mm/hwpoison: find subpage in hugetlb HWPOISON list

[Jiaqi Yan]

Adds the functionality to search a subpage's corresponding raw_hwp_page
in hugetlb page's HWPOISON list. This functionality can also tell if a
subpage is a raw HWPOISON page.

Exports this functionality to be immediately used in the read operation
for hugetlbfs.

Any reason why you decided to add the following to linux/mm.h instead of
linux/hugetlb.h?  Since it is hugetlb specific I would have thought
hugetlb.h was more appropriate.

IIUC, in rare error cases a hugetlb page can be poisoned WITHOUT a
raw_hwp_list.  This is indicated by the hugetlb page specific flag
RawHwpUnreliable or folio_test_hugetlb_raw_hwp_unreliable().

Looks like this routine does not consider that case.  Seems like it should
always return the passed subpage if folio_test_hugetlb_raw_hwp_unreliable()
is true?

Thanks for catching this. I wonder should this routine consider
RawHwpUnreliable or should the caller do.

find_raw_hwp_page now returns raw_hwp_page* in the llist entry to
caller (valid one at the moment), but once RawHwpUnreliable is set,
all the raw_hwp_page in the llist will be kfree(), and the returned
value becomes dangling pointer to caller (if the caller holds that
caller long enough). Maybe returning a bool would be safer to the
caller? If the routine returns bool, then checking RawHwpUnreliable
can definitely be within the routine.

Another option is, this routine simply doesn one thing: find a
raw_hwp_page in raw_hwp_list for a subpage. But the caller needs to 1)
test RawHwpUnreliable before calls into the routine, and 2) test
RawHwpUnreliable before access returned raw_hwp_page*. I think 2nd
option will be error-prone and the 1st option is a better one.

Maybe I am over-thinking. What do you think?

I think the check for RawHwpUnreliable should be within this routine.
Looking closer at the code, I do not see any way to synchronize this.
It looks like manipulation in the memory-failure code would be
synchronized via the mf_mutex.  However, I do not see how traversal and
freeing of the raw_hwp_list  called from __update_and_free_hugetlb_folio
is synchronized against memory-failure code modifying the list.

Naoya, can you provide some thoughts?

I think racing code accessing the raw_hwp_list is very unlikely.
However, it is possible and should be considered.

Thanks for elaborating the issue.  I think that making find_raw_hwp_page() and
folio_clear_hugetlb_hwpoison() do their works within mf_mutex can be one solution.
try_memory_failure_hugetlb(), one of the callers of folio_clear_hugetlb_hwpoison(),
already calls it within mf_mutex, so some wrapper might be needed to implement
calling path from __update_and_free_hugetlb_folio() to take mf_mutex.

It might be a concern that mf_mutex is a big lock to cover overall hwpoison
subsystem, but I think that the impact is not so big if the changed code paths
take mf_mutex only after checking hwpoisoned hugepage.  Maybe using folio_lock
to synchronize accesses to the raw_hwp_list could be possible, but currently
__get_huge_page_for_hwpoison() calls folio_set_hugetlb_hwpoison() without
folio_lock, so this approach needs update on locking rule and it sounds more
error-prone to me.

Thanks,
Naoya Horiguchi

Thanks Naoya, since memory_failure is the main user of raw_hwp_list, I
agree mf_mutex could help to sync its two del_all operations (one from
try_memory_failure_hugetlb and one from
__update_and_free_hugetlb_folio).

I still want to ask a perhaps stupid question, somewhat related to how
to implement find_raw_hwp_page() correctly. It seems
llist_for_each_safe should only be used to traverse after list entries
already *deleted* via llist_del_all. But the llist_for_each_safe calls
in memory_failure today is used *directly* on the raw_hwp_list. This
is quite different from other users of llist_for_each_safe (for
example, kernel/bpf/memalloc.c). Why is it correct? I guess mostly
because they are sync-ed under mf_mutex (except the missing coverage
on __update_and_free_hugetlb_folio)?

Oh, I don't noticed that when writing the original code. (I just chose
llist_for_each_safe because I just wanted struct llist_node as a singly
linked list.)

Yes, and there seems no good reason to use the macro llist_for_each_safe
here.  I think it's OK to switch to simpler one like list_for_each which
should be supposed to be called directly.  To do this, struct raw_hwp_page
need to have @node (typed struct list_head instead of struct llist_node).

And maybe because you can avoid doing INIT_LIST_HEAD (which seems
doable in folio_set_hugetlb_hwpoison if hugepage is hwpoison-ed for
the first time)?

I will start to work on a separate patch to switch to list_head, and
make sure operations from __update_and_free_hugetlb_folio and
memory_failure are serialized (hopefully without intro new locks and
just use mf_mutex).

Hi Naoya, a maybe-stupid question on list vs llist: _hugetlb_hwpoison
in folio is a void*. struct list_head is composed of two pointers to
list_node (prev and next) so folio just can't hold a list_head in the
_hugetlb_hwpoison field, right? llist_head on the other hand only
contains one pointer to llist_node first. I wonder if this is one of
the reason you picked llist instead of list in the first place.

The reason I ask is while I was testing my refactor draft, I
constantly see the refcount of the 3rd subpage in the folio got
corrupted. I am not sure about the exact reason but it feels to me
related to the above reason.

Yes, that's one reason to use llist_head, and another (minor) reason is that
we don't need doubly-linked list here.

Hi Mike,

Now looking again this, I think concurrent adding and deleting are
fine with each other and with themselves, because raw_hwp_list is
lock-less llist.

As for synchronizing traversal with adding and deleting, I wonder is
it a good idea to make __update_and_free_hugetlb_folio hold
hugetlb_lock before it folio_clear_hugetlb_hwpoison(which traverse +
delete raw_hwp_list)? In hugetlb, get_huge_page_for_hwpoison already
takes hugetlb_lock; it seems to me __update_and_free_hugetlb_folio is
missing the lock.

Hi Naoya,

Even with hugetlb_lock, I think we should still fix
__folio_free_raw_hwp: call llist_del_all first, then traverse the list
and free raw_hwp_page entries. Then folio_clear_hugetlb_hwpoison from
both memory_failure and hugetlb will be safe given llist_del_all on
llist is safe with itself.

In my v2, I tried both (1.taking hugetlb in
__update_and_free_hugetlb_folio, 2. call llist_del_all first in
__folio_free_raw_hwp). I also changed find_raw_hwp_page to
is_raw_hwp_subpage (only returns bool, and takes hugetlb_lock for
traversing raw_hwp_list). So far I didn't run into any problems with
my selftest.

Correct.

I do not think the lock is needed.  However, while looking more closely
at this I think I discovered another issue.
This is VERY subtle.
Perhaps Naoya can help verify if my reasoning below is correct.

In __update_and_free_hugetlb_folio we are not operating on a hugetlb page.
Why is this?
Before calling update_and_free_hugetlb_folio we call remove_hugetlb_folio.
The purpose of remove_hugetlb_folio is to remove the huge page from the
list AND compound page destructor indicating this is a hugetlb page is changed.
This is all done while holding the hugetlb lock.  So, the test for
folio_test_hugetlb(folio) is false.

We have technically a compound non-hugetlb page with a non-null raw_hwp_list.

Important note: at this time we have not reallocated vmemmap pages if
hugetlb page was vmemmap optimized.  That is done later in
__update_and_free_hugetlb_folio.

The 'good news' is that after this point get_huge_page_for_hwpoison will
not recognize this as a hugetlb page, so nothing will be added to the
list.  There is no need to worry about entries being added to the list
during traversal.

The 'bad news' is that if we get a memory error at this time we will
treat it as a memory error on a regular compound page.  So,
TestSetPageHWPoison(p) in memory_failure() may try to write a read only
struct page. :(

At least I think this is an issue.

Would it help if dissolve_free_huge_page doesn't unlock hugetlb_lock
until update_and_free_hugetlb_folio is done, or basically until
dissolve_free_huge_page is done?

TestSetPageHWPoison in memory_failure is called after
try_memory_failure_hugetlb, and folio_test_hugetlb is tested within
__get_huge_page_for_hwpoison, which is wrapped by the hugetlb_lock. So
by the time dissolve_free_huge_page returns, subpages already go
through hugetlb_vmemmap_restore and __destroy_compound_gigantic_folio
and become non-compound raw pages (folios). Now
folio_test_hugetlb(p)=false will be correct for memory_failure, and it
can recover p as a dissolved non-hugetlb page.

Unfortunately, update_and_free_hugetlb_folio is designed to be called
without locks held.  This is because we can not hold any locks while
allocating vmemmap pages.

I'll try to think of some way to restructure the code.  IIUC, this is a
potential general issue, not just isolated to memory error handling.

Considering this issue as one specific to memory error handling, checking
HPG_vmemmap_optimized in __get_huge_page_for_hwpoison() might be helpful to
detect the race.  Then, an idea like the below diff (not tested) can make
try_memory_failure_hugetlb() retry (with retaking hugetlb_lock) to wait
for complete the allocation of vmemmap pages.

The hugetlb specific page flags (HPG_vmemmap_optimized here) reside in
the folio->private field.

In the case where the folio is a non-hugetlb folio, the folio->private field
could be any arbitrary value.  As such, the test for vmemmap_optimized may
return a false positive.  We could end up retrying for an arbitrarily
long time.

I am looking at how to restructure the code which removes and frees
hugetlb pages so that folio_test_hugetlb() would remain true until
vmemmap pages are allocated.  The easiest way to do this would introduce
another hugetlb lock/unlock cycle in the page freeing path.  This would
undo some of the speedups in the series:

Perhaps something like this?  Minimal testing.

Subject: [PATCH] hugetlb: Do not clear hugetlb dtor until allocating vmemmap

Freeing a hugetlb page and releasing base pages back to the underlying
allocator such as buddy or cma is performed in two steps:
- remove_hugetlb_folio() is called to remove the folio from hugetlb
  lists, get a ref on the page and remove hugetlb destructor.  This
  all must be done under the hugetlb lock.  After this call, the page
  can be treated as a normal compound page or a collection of base
  size pages.
- update_and_free_hugetlb_folio() is called to allocate vmemmap if
  needed and the free routine of the underlying allocator is called
  on the resulting page.  We can not hold the hugetlb lock here.

One issue with this scheme is that a memory error could occur between
these two steps.  In this case, the memory error handling code treats
the old hugetlb page as a normal compound page or collection of base
pages.  It will then try to SetPageHWPoison(page) on the page with an
error.  If the page with error is a tail page without vmemmap, a write
error will occur when trying to set the flag.

Address this issue by modifying remove_hugetlb_folio() and
update_and_free_hugetlb_folio() such that the hugetlb destructor is not
cleared until after allocating vmemmap.  Since clearing the destructor
required holding the hugetlb lock, the clearing is done in
remove_hugetlb_folio() if the vmemmap is present.  This saves a
lock/unlock cycle.  Otherwise, destructor is cleared in
update_and_free_hugetlb_folio() after allocating vmemmap.

Note that this will leave hugetlb pages in a state where they are marked
free (by hugetlb specific page flag) and have a ref count.  This is not
a normal state.  The only code that would notice is the memory error
code, and it is set up to retry in such a case.

A subsequent patch will create a routine to do bulk processing of
vmemmap allocation.  This will eliminate a lock/unlock cycle for each
hugetlb page in the case where we are freeing a bunch of pages.

Can this test on vmemmap_optimized still tell us if we should
__clear_hugetlb_destructor? From my reading:
1. If a hugetlb folio is still vmemmap optimized in
__remove_hugetlb_folio, __remove_hugetlb_folio won't
__clear_hugetlb_destructor.
2. Then hugetlb_vmemmap_restore in dissolve_free_huge_page will clear
HPG_vmemmap_optimized if it succeeds.
3. Now when dissolve_free_huge_page gets into
__update_and_free_hugetlb_folio, we will see clear_dtor to be false
and __clear_hugetlb_destructor won't be called.

Or maybe I misunderstood, and what you really want to do is never
__clear_hugetlb_destructor so that folio_test_hugetlb is always true?

Good catch!  That is indeed a problem with this patch.

No, that was a bug with this patch.

We could ALWAYS wait until __update_and_free_hugetlb_folio to clear the
hugetlb destructor.  However, we have to take hugetlb lock to clear it.
If the page does not have vmemmap optimized, the we can clear the
destructor earlier in __remove_hugetlb_folio and avoid the lock/unlock
cycle.  In the past, we have had complaints about the time required to
allocate and free a large quantity of hugetlb pages.  Most of that time
is spent in the low level allocators.  However, I do not want to add
something like an extra lock/unlock cycle unless absolutely necessary.

I'll try to think of a cleaner and more fool proof way to address this.

IIUC, this is an existing issue.  Your patch series does not depend
this being fixed.

[PATCH v1 2/3] hugetlbfs: improve read HWPOISON hugepage

[Jiaqi Yan]

When a hugepage contains HWPOISON pages, read() fails to read any byte
of the hugepage and returns -EIO, although many bytes in the HWPOISON
hugepage are readable.

Improve this by allowing hugetlbfs_read_iter returns as many bytes as
possible. For a requested range [offset, offset + len) that contains
HWPOISON page, return [offset, first HWPOISON page addr); the next read
attempt will fail and return -EIO.

I intended to make this routine (mostly find_raw_hwp_page) to be
serialized with folio_clear_hugetlb_hwpoison() and
hwpoison_user_mappings() in try_memory_failure_hugetlb(). They don't
directly affect the raw_hwp_list. I can remove the lock in v2.

[PATCH v1 3/3] selftests/mm: add tests for HWPOISON hugetlbfs read

[Jiaqi Yan]

Add tests for the improvement made to read operations on HWPOISON
hugetlb page with different read granularities.

0) Simple regression test on read.
1) Sequential read page by page should succeed until encounters the 1st
   raw HWPOISON subpage.
2) After skip raw HWPOISON subpage by lseek, read always succeeds.

Re: [PATCH v1 3/3] selftests/mm: add tests for HWPOISON hugetlbfs read

Hello,

kernel test robot noticed "kernel-selftests.mm.hugepage-vmemmap.fail" on:

(we know that this commit adds hugetlb-read-hwpoison test, so we actually
want to seek some advice by this report, below will mention further)

commit: d84de15119b74f10be3c0a369561ca9b452d07d7 ("[PATCH v1 3/3] selftests/mm: add tests for HWPOISON hugetlbfs read")

patch subject: [PATCH v1 3/3] selftests/mm: add tests for HWPOISON hugetlbfs read

in testcase: kernel-selftests
version: kernel-selftests-x86_64-60acb023-1_20230329
with following parameters:

	sc_nr_hugepages: 2
	group: mm

test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt


compiler: gcc-11
test machine: 36 threads 1 sockets Intel(R) Core(TM) i9-10980XE CPU @ 3.00GHz (Cascade Lake) with 32G memory

(please refer to attached dmesg/kmsg for entire log/backtrace)

from below log [1], the new added hugetlb-read-hwpoison test passed.
but will fail while running hugepage-vmemmap test later as:

# selftests: mm: hugepage-vmemmap
# mmap: Cannot allocate memory
not ok 10 selftests: mm: hugepage-vmemmap # exit=1

hugepage-vmemmap can pass while testing with parent kernel, as below [2]

at the same time, we observed lots of
"Not enough free huge pages to test, exiting!"
for various testing.

any advice for this behavior?

BTW, the system upon which we did this test has 32G memory.
not sure if there is a recommended memory size to run these tests?

Thanks!

        cd lkp-tests
        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.

Thanks for putting this together.

I recall discussing this some time back, and deciding to wait and see
how HGM would progress.  Since it may be some time before HGM goes
upstream, it would be reasonable to consider this again.

One quick question.
Do you have an actual use case for this?  It certainly is an improvement
over existing functionality.  However, I am not aware of too many (?any?)
users actually doing read() calls on hugetlb files.

This improvement actually does NOT depend on HGM at all. No page table
related stuff involved here. The other RFC [2] I sent earlier DOES require
HGM. This improvement was brought up by James when we were working on [2].
In "Future Work" section of the cover letter, I thought HGM was needed but
soon I found I was wrong.

I don't have any use case. I did search on Github for around half a hour
and all the hugetlb usages are done via mmap.

Right, this has no HGM dependencies and is actually the only way I can think
of for users to extract some information from a poisoned hugetlb page.

Ok, I was mostly curious as mmap seems to be the most common way of
accessing hugetlb pages.

Even though there is not a known use case today, I think this could be
useful for the reason above: extracting data from a poisoned hugetlb page.
Without HGM this is the only way to extract such data.

Unfortunately, read() is not an option for sysV shared memory or private
mappings.  HGM would help there.
