[PATCH v2 0/9] convert hugetlb_cgroup helper functions to folios

[Sidhartha Kumar]

This patch series continues the conversion of hugetlb code from being
managed in pages to folios by converting many of the hugetlb_cgroup helper
functions to use folios. This allows the core hugetlb functions to pass in
a folio to these helper functions.

This series depends on my previous patch series which begins the hugetlb
folio conversion[1], both series pass the LTP hugetlb test cases.


[1] https://lore.kernel.org/lkml/20220922154207.1575343-1-sidhartha.kumar@oracle.com/

v1 -> v2
-fix folio_test_hugetlb_freed() check in alloc_and_dissolve_huge_page
-add more folio conversions to unmap_and_move_huge_page in patch 9
-collect review-bys from Mike Kravetz
-rebased on next-20221101 and mm-unstable

[PATCH v2 1/9] mm/hugetlb_cgroup: convert __set_hugetlb_cgroup() to folios

[Sidhartha Kumar]

Change __set_hugetlb_cgroup() to use folios so it is explicit that the
function operates on a head page.

[PATCH v2 2/9] mm/hugetlb_cgroup: convert hugetlb_cgroup_from_page() to folios

[Sidhartha Kumar]

Introduce folios in __remove_hugetlb_page() by converting
hugetlb_cgroup_from_page() to use folios.

Also gets rid of unsed hugetlb_cgroup_from_page_resv() function.

I suggest reworking the code here to the following (Looks simple for me).

int i = rsvd ? SUBPAGE_INDEX_CGROUP_RSVD : SUBPAGE_INDEX_CGROUP;

return (void *)page_private(folio_page(folio, i));

Seems like a variant of set_compound_page_dtor() for folio is missing,
e.g. set_large_folio_dtor(). It's better to add it in this series.

Thanks.

Hi Muchun thanks for taking a look,

Would it be ok to add this functionality in a separate patch series? 
Some of the earlier patches in this series were modified by Hugh's 
series[1] so I'm not sure how a v3 of this series would look now. Let me 
know which approach you would prefer.


Thanks,

Muchun had the same comment I had in v1 about the need for a routine to
set the destructor of a folio.  Since this will be added in a subsequent
series,

Is this safe?  I was reviewing a different patch today, and I spotted
this.  With THP, we can relatively easily hit this case:

struct page points to a page with pfn 0x40305, in a folio of order 2.
We call page_folio() on it and the resulting pointer is for the folio
with pfn 0x40304.
If we don't have our own refcount (or some other protection ...) against
freeing, the folio can now be freed and reallocated.  Say it's now part
of an order-3 folio.
Our 'folio' pointer is now actually a pointer to a tail page, and we
have various assertions that a folio pointer doesn't point to a tail
page, so they trigger.

It seems to me that this ...

        /*
         * The page might have been dissolved from under our feet, so make sure
         * to carefully check the state under the lock.
         * Return success when racing as if we dissolved the page ourselves.
         */
        spin_lock_irq(&hugetlb_lock);
        if (folio_test_hugetlb(folio)) {
                h = folio_hstate(folio);
        } else {
                spin_unlock_irq(&hugetlb_lock);
                return 0;
        }

implies that we don't have our own reference on the folio, so we might
find a situation where the folio pointer we have is no longer a folio
pointer.

Maybe the page_folio() call should be moved inside the hugetlb_lock
protection?  Is that enough?  I don't know enough about how hugetlb
pages are split, freed & allocated to know what's going on.

But then we _drop_ the lock, and keep referring to ...

And I fall back to saying "I don't know enough to know if this is safe".

If the folio became free and reallocated would this be considered a 
success? If the folio is no longer a hugetlb folio, 
isolate_or_dissolve_huge_page() returns as if it dissolved the page itself.

Later in the call stack, within alloc_and_dissolve_hugetlb_folio() there is

	if (!folio_test_hugetlb(old_folio)) {
		/*
		 * Freed from under us. Drop new_folio too.
		 */
		goto free_new;
	}

which would imply it is safe for the old_folio to have been dropped/freed.

Your analysis is correct.

This is not safe because we hold no locks or references.  The folio
pointer obtained via page_folio(page) may not be valid when calling
folio_test_hugetlb(folio) and later.

My bad for the Reviewed-by: :(

The above was OK when using struct page instead of folio.  The 'racy'
part was getting the ref count on the head page.  It was OK because this
was only a check to see if we should TRY to isolate or dissolve.  The
code to actually isolate or dissolve would take the appropriate locks.

I'm afraid the code is now making even more use of a potentially invalid
folio.  Here is how the above now looks in v6.3:

	spin_unlock_irq(&hugetlb_lock);

	/*
	 * Fence off gigantic pages as there is a cyclic dependency between
	 * alloc_contig_range and them. Return -ENOMEM as this has the effect
	 * of bailing out right away without further retrying.
	 */
	if (hstate_is_gigantic(h))
		return -ENOMEM;

	if (folio_ref_count(folio) && isolate_hugetlb(folio, list))
		ret = 0;
	else if (!folio_ref_count(folio))
		ret = alloc_and_dissolve_hugetlb_folio(h, folio, list);

Looks like that potentially invalid folio is being passed to other
routines.  Previous code would take lock and revalidate that struct page
was still a hugetlb page.  We can not do the same with a folio.

I was looking at this more closely and need a bit of clarification.  As
mentioned, your analysis is correct.  However, it appears that there is
other code doing:

folio = page_folio(page);
...
if (folio_test_hugetlb(folio))

without holding a folio ref or some type of lock.  split_huge_pages_all()
is one such example.

So, either this code has the same issue or there are folio routines that
can be called without holding a ref/lock.  The kerneldoc for
folio_test_hugetlb says "Caller should have a reference on the folio to
prevent it from being turned into a tail page.".  However, is that mostly
to make sure the returned value is consistent/valid?  Can it really lead
to an assert if folio pointer is changed to point to something else?

Upon further thought, I think we should move the page_folio() inside the
lock just to be more correct.

page_count() is doing 'folio_ref_count(page_folio(page));' and there I suspect
there are many places doing page_count without taking a page ref or locking.
So, it seems like this would also be safe?

Perhaps I spoke too soon.  Yes, we pass a potentially invalid folio
pointer to isolate_hugetlb() and alloc_and_dissolve_hugetlb_folio().
However, it seems the validation they perform should be sufficient.

bool isolate_hugetlb(struct folio *folio, struct list_head *list)
{
	bool ret = true;

	spin_lock_irq(&hugetlb_lock);
	if (!folio_test_hugetlb(folio) ||
	    !folio_test_hugetlb_migratable(folio) ||
	    !folio_try_get(folio)) {
		ret = false;
		goto unlock;


static int alloc_and_dissolve_hugetlb_folio(struct hstate *h,
			struct folio *old_folio, struct list_head *list)
{
	...
retry:
	spin_lock_irq(&hugetlb_lock);
	if (!folio_test_hugetlb(old_folio)) {
		...
	} else if (folio_ref_count(old_folio)) {
		...
	} else if (!folio_test_hugetlb_freed(old_folio)) {
		...
		goto retry;
	} else {
		/*
		 * Ok, old_folio is still a genuine free hugepage.

Upon further consideration, I do not see an issue with the existing
code.  If there are issues with calling folio_test_hugetlb() or
folio_ref_count() on a potentially invalid folio pointer, then we do
have issues here.  However, such an issue would be more widespread as
there is more code doing the same.
