[patch 01/15] ipc/mqueue.c: change __do_notify() to bypass check_kill_permission()

[Andrew Morton]

From: Oleg Nesterov <oleg@redhat.com>
Subject: ipc/mqueue.c: change __do_notify() to bypass check_kill_permission()

Commit cc731525f26a ("signal: Remove kernel interal si_code magic")
changed the value of SI_FROMUSER(SI_MESGQ), this means that mq_notify() no
longer works if the sender doesn't have rights to send a signal.

Change __do_notify() to use do_send_sig_info() instead of kill_pid_info()
to avoid check_kill_permission().

This needs the additional notify.sigev_signo != 0 check, shouldn't we
change do_mq_notify() to deny sigev_signo == 0 ?

Test-case:

	#include <signal.h>
	#include <mqueue.h>
	#include <unistd.h>
	#include <sys/wait.h>
	#include <assert.h>

	static int notified;

	static void sigh(int sig)
	{
		notified = 1;
	}

	int main(void)
	{
		signal(SIGIO, sigh);

		int fd = mq_open("/mq", O_RDWR|O_CREAT, 0666, NULL);
		assert(fd >= 0);

		struct sigevent se = {
			.sigev_notify	= SIGEV_SIGNAL,
			.sigev_signo	= SIGIO,
		};
		assert(mq_notify(fd, &se) == 0);

		if (!fork()) {
			assert(setuid(1) == 0);
			mq_send(fd, "",1,0);
			return 0;
		}

		wait(NULL);
		mq_unlink("/mq");
		assert(notified);
		return 0;
	}

[patch 02/15] mm, memcg: fix error return value of mem_cgroup_css_alloc()

[Andrew Morton]

From: Yafang Shao <laoar.shao@gmail.com>
Subject: mm, memcg: fix error return value of mem_cgroup_css_alloc()

When I run my memcg testcase which creates lots of memcgs, I found
there're unexpected out of memory logs while there're still enough
available free memory.  The error log is, mkdir: cannot create directory
'foo.65533': Cannot allocate memory

The reason is when we try to create more than MEM_CGROUP_ID_MAX memcgs, an
-ENOMEM errno will be set by mem_cgroup_css_alloc(), but the right errno
should be -ENOSPC "No space left on device", which is an appropriate errno
for userspace's failed mkdir.

As the errno really misled me, we should make it right.  After this patch,
the error log will be "mkdir: cannot create directory 'foo.65533': No
space left on device"

[patch 03/15] mm/page_alloc: fix watchdog soft lockups during set_zone_contiguous()

The issue becomes visible when having a lot of memory (e.g., 4TB) assigned
to a single NUMA node - a system that can easily be created using QEMU. 
Inside VMs on a hypervisor with quite some memory overcommit, this is
fairly easy to trigger.

[patch 05/15] scripts/decodecode: fix trapping instruction formatting

[Andrew Morton]

From: Ivan Delalande <colona@arista.com>
Subject: scripts/decodecode: fix trapping instruction formatting

If the trapping instruction contains a ':', for a memory access through
segment registers for example, the sed substitution will insert the '*'
marker in the middle of the instruction instead of the line address:

	2b:   65 48 0f c7 0f          cmpxchg16b %gs:*(%rdi)          <-- trapping instruction

I started to think I had forgotten some quirk of the assembly syntax
before noticing that it was actually coming from the script.  Fix it to
add the address marker at the right place for these instructions:

	28:   49 8b 06                mov    (%r14),%rax
	2b:*  65 48 0f c7 0f          cmpxchg16b %gs:(%rdi)           <-- trapping instruction
	30:   0f 94 c0                sete   %al

[patch 06/15] arch/x86/kvm/svm/sev.c: change flag passed to GUP fast in sev_pin_memory()

[Andrew Morton]

From: Janakarajan Natarajan <Janakarajan.Natarajan@amd.com>
Subject: arch/x86/kvm/svm/sev.c: change flag passed to GUP fast in sev_pin_memory()

When trying to lock read-only pages, sev_pin_memory() fails because
FOLL_WRITE is used as the flag for get_user_pages_fast().

Commit 73b0140bf0fe ("mm/gup: change GUP fast to use flags rather than a
write 'bool'") updated the get_user_pages_fast() call sites to use flags,
but incorrectly updated the call in sev_pin_memory().  As the original
coding of this call was correct, revert the change made by that commit.

[patch 07/15] eventpoll: fix missing wakeup for ovflist in ep_poll_callback

[Andrew Morton]

From: Khazhismel Kumykov <khazhy@google.com>
Subject: eventpoll: fix missing wakeup for ovflist in ep_poll_callback

In the event that we add to ovflist, before 339ddb53d373 we would be woken
up by ep_scan_ready_list, and did no wakeup in ep_poll_callback.  With
that wakeup removed, if we add to ovflist here, we may never wake up. 
Rather than adding back the ep_scan_ready_list wakeup - which was
resulting in unnecessary wakeups, trigger a wake-up in ep_poll_callback.

We noticed that one of our workloads was missing wakeups starting with
339ddb53d373 and upon manual inspection, this wakeup seemed missing to me.
With this patch added, we no longer see missing wakeups.  I haven't yet
tried to make a small reproducer, but the existing kselftests in
filesystem/epoll passed for me with this patch.

[patch 08/15] scripts/gdb: repair rb_first() and rb_last()

[Andrew Morton]

From: Aymeric Agon-Rambosson <aymeric.agon@yandex.com>
Subject: scripts/gdb: repair rb_first() and rb_last()

The current implementations of the rb_first() and rb_last() gdb functions
have a variable that references itself in its instanciation, which causes
the function to throw an error if a specific condition on the argument is
met.  The original author rather intended to reference the argument and
made a typo.  Referring the argument instead makes the function work as
intended.

[patch 09/15] mm/slub: fix incorrect interpretation of s->offset

[Andrew Morton]

From: Waiman Long <longman@redhat.com>
Subject: mm/slub: fix incorrect interpretation of s->offset

In a couple of places in the slub memory allocator, the code uses
"s->offset" as a check to see if the free pointer is put right after the
object.  That check is no longer true with commit 3202fa62fb43 ("slub:
relocate freelist pointer to middle of object").

As a result, echoing "1" into the validate sysfs file, e.g.  of dentry,
may cause a bunch of "Freepointer corrupt" error reports like the
following to appear with the system in panic afterwards.

[   38.579769] =============================================================================
[   38.580845] BUG dentry(666:pmcd.service) (Tainted: G    B): Freepointer corrupt
[   38.581948] -----------------------------------------------------------------------------

To fix it, use the check "s->offset == s->inuse" in the new helper
function freeptr_outside_object() instead.  Also add another helper
function get_info_end() to return the end of info block (inuse + free
pointer if not overlapping with object).

[patch 10/15] percpu: make pcpu_alloc() aware of current gfp context

[Andrew Morton]

From: Filipe Manana <fdmanana@suse.com>
Subject: percpu: make pcpu_alloc() aware of current gfp context

Since 5.7-rc1, on btrfs we have a percpu counter initialization for which
we always pass a GFP_KERNEL gfp_t argument (this happens since commit
2992df73268f78 ("btrfs: Implement DREW lock")).  That is safe in some
contextes but not on others where allowing fs reclaim could lead to a
deadlock because we are either holding some btrfs lock needed for a
transaction commit or holding a btrfs transaction handle open.  Because of
that we surround the call to the function that initializes the percpu
counter with a NOFS context using memalloc_nofs_save() (this is done at
btrfs_init_fs_root()).

However it turns out that this is not enough to prevent a possible
deadlock because percpu_alloc() determines if it is in an atomic context
by looking exclusively at the gfp flags passed to it (GFP_KERNEL in this
case) and it is not aware that a NOFS context is set.  Because it thinks
it is in a non atomic context it locks the pcpu_alloc_mutex, which can
result in a btrfs deadlock when pcpu_balance_workfn() is running, has
acquired that mutex and is waiting for reclaim, while the btrfs task that
called percpu_counter_init() (and therefore percpu_alloc()) is holding
either the btrfs commit_root semaphore or a transaction handle (done at
fs/btrfs/backref.c:iterate_extent_inodes()), which prevents reclaim from
finishing as an attempt to commit the current btrfs transaction will
deadlock.

Lockdep reports this issue with the following trace:

This could be fixed by making btrfs pass GFP_NOFS instead of GFP_KERNEL to
percpu_counter_init() in contextes where it is not reclaim safe, however
that type of approach is discouraged since memalloc_[nofs|noio]_save()
were introduced.  Therefore this change makes pcpu_alloc() look up into an
existing nofs/noio context before deciding whether it is in an atomic
context or not.

[patch 11/15] kselftests: introduce new epoll60 testcase for catching lost wakeups

[Andrew Morton]

From: Roman Penyaev <rpenyaev@suse.de>
Subject: kselftests: introduce new epoll60 testcase for catching lost wakeups

This test case catches lost wake up introduced by:
  339ddb53d373 ("fs/epoll: remove unnecessary wakeups of nested epoll")

The test is simple: we have 10 threads and 10 event fds.  Each thread can
harvest only 1 event.  1 producer fires all 10 events at once and waits
that all 10 events will be observed by 10 threads.

In case of lost wakeup epoll_wait() will timeout and 0 will be returned.

Test case catches two sort of problems: forgotten wakeup on event, which
hits the ->ovflist list, this problem was fixed by:

  5a2513239750 ("eventpoll: fix missing wakeup for ovflist in ep_poll_callback")

the other problem is when several sequential events hit the same waiting
thread, thus other waiters get no wakeups.  Problem is fixed in the
following patch.

[patch 12/15] epoll: atomically remove wait entry on wake up

[Andrew Morton]

From: Roman Penyaev <rpenyaev@suse.de>
Subject: epoll: atomically remove wait entry on wake up

This patch does two things:

1. fixes lost wakeup introduced by:
  339ddb53d373 ("fs/epoll: remove unnecessary wakeups of nested epoll")

2. improves performance for events delivery.

The description of the problem is the following: if N (>1) threads are
waiting on ep->wq for new events and M (>1) events come, it is quite
likely that >1 wakeups hit the same wait queue entry, because there is
quite a big window between __add_wait_queue_exclusive() and the following
__remove_wait_queue() calls in ep_poll() function.  This can lead to lost
wakeups, because thread, which was woken up, can handle not all the events
in ->rdllist.  (in better words the problem is described here:
https://lkml.org/lkml/2019/10/7/905)

The idea of the current patch is to use init_wait() instead of
init_waitqueue_entry().  Internally init_wait() sets
autoremove_wake_function as a callback, which removes the wait entry
atomically (under the wq locks) from the list, thus the next coming wakeup
hits the next wait entry in the wait queue, thus preventing lost wakeups.

Problem is very well reproduced by the epoll60 test case [1].

Wait entry removal on wakeup has also performance benefits, because there
is no need to take a ep->lock and remove wait entry from the queue after
the successful wakeup.  Here is the timing output of the epoll60 test
case:

  With explicit wakeup from ep_scan_ready_list() (the state of the
  code prior 339ddb53d373):

    real    0m6.970s
    user    0m49.786s
    sys     0m0.113s

 After this patch:

   real    0m5.220s
   user    0m36.879s
   sys     0m0.019s

The other testcase is the stress-epoll [2], where one thread consumes
all the events and other threads produce many events:

  With explicit wakeup from ep_scan_ready_list() (the state of the
  code prior 339ddb53d373):

    threads  events/ms  run-time ms
          8       5427         1474
         16       6163         2596
         32       6824         4689
         64       7060         9064
        128       6991        18309

 After this patch:

    threads  events/ms  run-time ms
          8       5598         1429
         16       7073         2262
         32       7502         4265
         64       7640         8376
        128       7634        16767

 (number of "events/ms" represents event bandwidth, thus higher is
  better; number of "run-time ms" represents overall time spent
  doing the benchmark, thus lower is better)

Since commit a9e7c39fa9fd9 ("mm/vmscan.c: remove 7th argument of
isolate_lru_pages()"), the explanation of 'mode' argument has been
unnecessary.  Let's remove it.

[patch 15/15] mm: limit boost_watermark on small zones

[Andrew Morton]

From: Henry Willard <henry.willard@oracle.com>
Subject: mm: limit boost_watermark on small zones

Commit 1c30844d2dfe ("mm: reclaim small amounts of memory when an external
fragmentation event occurs") adds a boost_watermark() function which
increases the min watermark in a zone by at least pageblock_nr_pages or
the number of pages in a page block. On Arm64, with 64K pages and 512M
huge pages, this is 8192 pages or 512M. It does this regardless of the
number of managed pages managed in the zone or the likelihood of success.
This can put the zone immediately under water in terms of allocating pages
from the zone, and can cause a small machine to fail immediately due to
OoM. Unlike set_recommended_min_free_kbytes(), which substantially
increases min_free_kbytes and is tied to THP, boost_watermark() can be
called even if THP is not active. The problem is most likely to appear
on architectures such as Arm64 where pageblock_nr_pages is very large.

It is desirable to run the kdump capture kernel in as small a space as
possible to avoid wasting memory. In some architectures, such as Arm64,
there are restrictions on where the capture kernel can run, and therefore,
the space available. A capture kernel running in 768M can fail due to OoM
immediately after boost_watermark() sets the min in zone DMA32, where
most of the memory is, to 512M. It fails even though there is over 500M of
free memory. With boost_watermark() suppressed, the capture kernel can run
successfully in 448M.

This patch limits boost_watermark() to boosting a zone's min watermark only
when there are enough pages that the boost will produce positive results.
In this case that is estimated to be four times as many pages as
pageblock_nr_pages.

Mel said:

: There is no harm in marking it stable.  Clearly it does not happen very
: often but it's not impossible.  32-bit x86 is a lot less common now
: which would previously have been vulnerable to triggering this easily. 
: ppc64 has a larger base page size but typically only has one zone. 
: arm64 is likely the most vulnerable, particularly when CMA is
: configured with a small movable zone.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: fix NUMA node file count error in replace_page_cache()

Patch series "mm: memcontrol: charge swapin pages on instantiation", v2.

This patch series reworks memcg to charge swapin pages directly at
swapin time, rather than at fault time, which may be much later, or
not happen at all.

Changes in version 2:
- prevent double charges on pre-allocated hugepages in khugepaged
- leave shmem swapcache when charging fails to avoid double IO (Joonsoo)
- fix temporary accounting bug by switching rmap<->commit (Joonsoo)
- fix double swap charge bug in cgroup1/cgroup2 code gating
- simplify swapin error checking (Joonsoo)
- mm: memcontrol: document the new swap control behavior (Alex)
- review tags

The delayed swapin charging scheme we have right now causes problems:

- Alex's per-cgroup lru_lock patches rely on pages that have been
  isolated from the LRU to have a stable page->mem_cgroup; otherwise
  the lock may change underneath him. Swapcache pages are charged only
  after they are added to the LRU, and charging doesn't follow the LRU
  isolation protocol.

- Joonsoo's anon workingset patches need a suitable LRU at the time
  the page enters the swap cache and displaces the non-resident
  info. But the correct LRU is only available after charging.

- It's a containment hole / DoS vector. Users can trigger arbitrarily
  large swap readahead using MADV_WILLNEED. The memory is never
  charged unless somebody actually touches it.

- It complicates the page->mem_cgroup stabilization rules

In order to charge pages directly at swapin time, the memcg code base
needs to be prepared, and several overdue cleanups become a necessity:

To charge pages at swapin time, we need to always have cgroup
ownership tracking of swap records. We also cannot rely on
page->mapping to tell apart page types at charge time, because that's
only set up during a page fault.

To eliminate the page->mapping dependency, memcg needs to ditch its
private page type counters (MEMCG_CACHE, MEMCG_RSS, NR_SHMEM) in favor
of the generic vmstat counters and accounting sites, such as
NR_FILE_PAGES, NR_ANON_MAPPED etc.

To switch to generic vmstat counters, the charge sequence must be
adjusted such that page->mem_cgroup is set up by the time these
counters are modified.

The series is structured as follows:

1. Bug fixes
2. Decoupling charging from rmap
3. Swap controller integration into memcg
4. Direct swapin charging


This patch (of 19):

When replacing one page with another one in the cache, we have to decrease
the file count of the old page's NUMA node and increase the one of the new
NUMA node, otherwise the old node leaks the count and the new node
eventually underflows its counter.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: fix stat-corrupting race in charge moving

The move_lock is a per-memcg lock, but the VM accounting code that needs
to acquire it comes from the page and follows page->mem_cgroup under RCU
protection.  That means that the page becomes unlocked not when we drop
the move_lock, but when we update page->mem_cgroup.  And that assignment
doesn't imply any memory ordering.  If that pointer write gets reordered
against the reads of the page state - page_mapped, PageDirty etc.  the
state may change while we rely on it being stable and we can end up
corrupting the counters.

Place an SMP memory barrier to make sure we're done with all page state by
the time the new page->mem_cgroup becomes visible.

Also replace the open-coded move_lock with a lock_page_memcg() to make it
more obvious what we're serializing against.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: drop @compound parameter from memcg charging API

The memcg charging API carries a boolean @compound parameter that tells
whether the page we're dealing with is a hugepage. 
mem_cgroup_commit_charge() has another boolean @lrucare that indicates
whether the page needs LRU locking or not while charging.  The majority of
callsites know those parameters at compile time, which results in a lot of
naked "false, false" argument lists.  This makes for cryptic code and is a
breeding ground for subtle mistakes.

Thankfully, the huge page state can be inferred from the page itself and
doesn't need to be passed along.  This is safe because charging completes
before the page is published and somebody may split it.

Simplify the callsites by removing @compound, and let memcg infer the
state by using hpage_nr_pages() unconditionally.  That function does
PageTransHuge() to identify huge pages, which also helpfully asserts that
nobody passes in tail pages by accident.

The following patches will introduce a new charging API, best not to carry
over unnecessary weight.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: move out cgroup swaprate throttling

The cgroup swaprate throttling is about matching new anon allocations to
the rate of available IO when that is being throttled.  It's the io
controller hooking into the VM, rather than a memory controller thing.

Rename mem_cgroup_throttle_swaprate() to cgroup_throttle_swaprate(), and
drop the @memcg argument which is only used to check whether the preceding
page charge has succeeded and the fault is proceeding.

We could decouple the call from mem_cgroup_try_charge() here as well, but
that would cause unnecessary churn: the following patches convert all
callsites to a new charge API and we'll decouple as we go along.

------------------------------------------------------
From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: convert page cache to a new mem_cgroup_charge() API

The try/commit/cancel protocol that memcg uses dates back to when pages
used to be uncharged upon removal from the page cache, and thus couldn't
be committed before the insertion had succeeded.  Nowadays, pages are
uncharged when they are physically freed; it doesn't matter whether the
insertion was successful or not.  For the page cache, the transaction
dance has become unnecessary.

Introduce a mem_cgroup_charge() function that simply charges a newly
allocated page to a cgroup and sets up page->mem_cgroup in one single
step.  If the insertion fails, the caller doesn't have to do anything but
free/put the page.

Then switch the page cache over to this new API.

Subsequent patches will also convert anon pages, but it needs a bit more
prep work.  Right now, memcg depends on page->mapping being already set up
at the time of charging, so that it can maintain its own MEMCG_CACHE and
MEMCG_RSS counters.  For anon, page->mapping is set under the same pte
lock under which the page is publishd, so a single charge point that can
block doesn't work there just yet.

The following prep patches will replace the private memcg counters with
the generic vmstat counters, thus removing the page->mapping dependency,
then complete the transition to the new single-point charge API and delete
the old transactional scheme.

v2: leave shmem swapcache when charging fails to avoid double IO (Joonsoo)

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: prepare uncharging for removal of private page type counters

The uncharge batching code adds up the anon, file, kmem counts to
determine the total number of pages to uncharge and references to drop. 
But the next patches will remove the anon and file counters.

Maintain an aggregate nr_pages in the uncharge_gather struct.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: prepare move_account for removal of private page type counters

When memcg uses the generic vmstat counters, it doesn't need to do
anything at charging and uncharging time.  It does, however, need to
migrate counts when pages move to a different cgroup in move_account.

Prepare the move_account function for the arrival of NR_FILE_PAGES,
NR_ANON_MAPPED, NR_ANON_THPS etc.  by having a branch for files and a
branch for anon, which can then divided into sub-branches.

Subject: mm: memcontrol: prepare cgroup vmstat infrastructure for native anon counters

Anonymous compound pages can be mapped by ptes, which means that if we
want to track NR_MAPPED_ANON, NR_ANON_THPS on a per-cgroup basis, we have
to be prepared to see tail pages in our accounting functions.

Make mod_lruvec_page_state() and lock_page_memcg() deal with tail pages
correctly, namely by redirecting to the head page which has the
page->mem_cgroup set up.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: switch to native NR_FILE_PAGES and NR_SHMEM counters

Memcg maintains private MEMCG_CACHE and NR_SHMEM counters.  This
divergence from the generic VM accounting means unnecessary code overhead,
and creates a dependency for memcg that page->mapping is set up at the
time of charging, so that page types can be told apart.

Convert the generic accounting sites to mod_lruvec_page_state and friends
to maintain the per-cgroup vmstat counters of NR_FILE_PAGES and NR_SHMEM. 
The page is already locked in these places, so page->mem_cgroup is stable;
we only need minimal tweaks of two mem_cgroup_migrate() calls to ensure
it's set up in time.

Then replace MEMCG_CACHE with NR_FILE_PAGES and delete the private
NR_SHMEM accounting sites.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: switch to native NR_ANON_MAPPED counter

Memcg maintains a private MEMCG_RSS counter.  This divergence from the
generic VM accounting means unnecessary code overhead, and creates a
dependency for memcg that page->mapping is set up at the time of charging,
so that page types can be told apart.

Convert the generic accounting sites to mod_lruvec_page_state and friends
to maintain the per-cgroup vmstat counter of NR_ANON_MAPPED.  We use
lock_page_memcg() to stabilize page->mem_cgroup during rmap changes, the
same way we do for NR_FILE_MAPPED.

With the previous patch removing MEMCG_CACHE and the private NR_SHMEM
counter, this patch finally eliminates the need to have page->mapping set
up at charge time.  However, we need to have page->mem_cgroup set up by
the time rmap runs and does the accounting, so switch the commit and the
rmap callbacks around.

v2: fix temporary accounting bug by switching rmap<->commit (Joonsoo)

Subject: mm: memcontrol: switch to native NR_ANON_THPS counter

With rmap memcg locking already in place for NR_ANON_MAPPED, it's just a
small step to remove the MEMCG_RSS_HUGE wart and switch memcg to the
native NR_ANON_THPS accounting sites.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: convert anon and file-thp to new mem_cgroup_charge() API

With the page->mapping requirement gone from memcg, we can charge anon and
file-thp pages in one single step, right after they're allocated.

This removes two out of three API calls - especially the tricky commit
step that needed to happen at just the right time between when the page is
"set up" and when it's "published" - somewhat vague and fluid concepts
that varied by page type.  All we need is a freshly allocated page and a
memcg context to charge.

v2: prevent double charges on pre-allocated hugepages in khugepaged

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: prepare swap controller setup for integration

A few cleanups to streamline the swap controller setup:

- Replace the do_swap_account flag with cgroup_memory_noswap. This
  brings it in line with other functionality that is usually available
  unless explicitly opted out of - nosocket, nokmem.

- Remove the really_do_swap_account flag that stores the boot option
  and is later used to switch the do_swap_account. It's not clear why
  this indirection is/was necessary. Use do_swap_account directly.

- Minor coding style polishing

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: make swap tracking an integral part of memory control

Without swap page tracking, users that are otherwise memory controlled can
easily escape their containment and allocate significant amounts of memory
that they're not being charged for.  That's because swap does readahead,
but without the cgroup records of who owned the page at swapout, readahead
pages don't get charged until somebody actually faults them into their
page table and we can identify an owner task.  This can be maliciously
exploited with MADV_WILLNEED, which triggers arbitrary readahead
allocations without charging the pages.

Make swap swap page tracking an integral part of memcg and remove the
Kconfig options.  In the first place, it was only made configurable to
allow users to save some memory.  But the overhead of tracking cgroup
ownership per swap page is minimal - 2 byte per page, or 512k per 1G of
swap, or 0.04%.  Saving that at the expense of broken containment
semantics is not something we should present as a coequal option.

The swapaccount=0 boot option will continue to exist, and it will
eliminate the page_counter overhead and hide the swap control files, but
it won't disable swap slot ownership tracking.

This patch makes sure we always have the cgroup records at swapin time;
the next patch will fix the actual bug by charging readahead swap pages at
swapin time rather than at fault time.

v2: fix double swap charge bug in cgroup1/cgroup2 code gating

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: charge swapin pages on instantiation

Right now, users that are otherwise memory controlled can easily escape
their containment and allocate significant amounts of memory that they're
not being charged for.  That's because swap readahead pages are not being
charged until somebody actually faults them into their page table.  This
can be exploited with MADV_WILLNEED, which triggers arbitrary readahead
allocations without charging the pages.

There are additional problems with the delayed charging of swap pages:

1. To implement refault/workingset detection for anonymous pages, we
   need to have a target LRU available at swapin time, but the LRU is not
   determinable until the page has been charged.

2. To implement per-cgroup LRU locking, we need page->mem_cgroup to be
   stable when the page is isolated from the LRU; otherwise, the locks
   change under us.  But swapcache gets charged after it's already on the
   LRU, and even if we cannot isolate it ourselves (since charging is not
   exactly optional).

The previous patch ensured we always maintain cgroup ownership records for
swap pages.  This patch moves the swapcache charging point from the fault
handler to swapin time to fix all of the above problems.

v2: simplify swapin error checking (Joonsoo)

Swapin faults were the last event to charge pages after they had already
been put on the LRU list.  Now that we charge directly on swapin, the
lrucare portion of the charge code is unused.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: memcontrol: update page->mem_cgroup stability rules

The previous patches have simplified the access rules around
page->mem_cgroup somewhat:

1. We never change page->mem_cgroup while the page is isolated by
   somebody else.  This was by far the biggest exception to our rules and
   it didn't stop at lock_page() or lock_page_memcg().

2. We charge pages before they get put into page tables now, so the
   somewhat fishy rule about "can be in page table as long as it's still
   locked" is now gone and boiled down to having an exclusive reference to
   the page.

Document the new rules.  Any of the following will stabilize the
page->mem_cgroup association:

- the page lock
- LRU isolation
- lock_page_memcg()
- exclusive access to the page

The Power ISA mandates that all writes to the Authority Mask Register
(AMR) must always be preceded as well as succeeded by a
context-synchronizing instruction.  This applies to both the privileged
and unprivileged variants of the Move To AMR instruction.

For powerpc, PKEY_DISABLE_WRITE and PKEY_DISABLE_ACCESS are redefined only
if the system headers already define them.  Otherwise, the test fails to
compile due to their absence.  This makes sure that they are always
defined irrespective of them being present in the system headers.

------------------------------------------------------
From: Shakeel Butt <shakeelb@google.com>
Subject: memcg: expose root cgroup's memory.stat

One way to measure the efficiency of memory reclaim is to look at the
ratio (pgscan+pfrefill)/pgsteal.  However at the moment these stats are
not updated consistently at the system level and the ratio of these are
not very meaningful.  The pgsteal and pgscan are updated for only global
reclaim while pgrefill gets updated for global as well as cgroup reclaim.

Please note that this difference is only for system level vmstats.  The
cgroup stats returned by memory.stat are actually consistent.  The
cgroup's pgsteal contains number of reclaimed pages for global as well as
cgroup reclaim.  So, one way to get the system level stats is to get these
stats from root's memory.stat, so, expose memory.stat for the root cgroup.

	from Johannes Weiner:
	There are subtle differences between /proc/vmstat and
	memory.stat, and cgroup-aware code that wants to watch the full
	hierarchy currently has to know about these intricacies and
	translate semantics back and forth.

	Generally having the fully recursive memory.stat at the root
	level could help a broader range of usecases.

Starting from v4.19 commit 29ef680ae7c2 ("memcg, oom: move out_of_memory

page faults.  Now it implements the same semantics as global OOM killer:
allocation context invokes OOM killer and keeps retrying until success.

From: David Hildenbrand <david@redhat.com>
Subject: device-dax: don't leak kernel memory to user space after unloading kmem

Assume we have kmem configured and loaded:
  [root@localhost ~]# cat /proc/iomem
  ...
  140000000-33fffffff : Persistent Memory$
    140000000-1481fffff : namespace0.0
    150000000-33fffffff : dax0.0
      150000000-33fffffff : System RAM

Assume we try to unload kmem. This force-unloading will work, even if
memory cannot get removed from the system.
  [root@localhost ~]# rmmod kmem
  [   86.380228] removing memory fails, because memory [0x0000000150000000-0x0000000157ffffff] is onlined
  ...
  [   86.431225] kmem dax0.0: DAX region [mem 0x150000000-0x33fffffff] cannot be hotremoved until the next reboot

Now, we can reconfigure the namespace:
  [root@localhost ~]# ndctl create-namespace --force --reconfig=namespace0.0 --mode=devdax
  [  131.409351] nd_pmem namespace0.0: could not reserve region [mem 0x140000000-0x33fffffff]dax
  [  131.410147] nd_pmem: probe of namespace0.0 failed with error -16namespace0.0 --mode=devdax
  ...

This fails as expected due to the busy memory resource, and the memory
cannot be used. However, the dax0.0 device is removed, and along its name.

The name of the memory resource now points at freed memory (name of the
device).
  [root@localhost ~]# cat /proc/iomem
  ...
  140000000-33fffffff : Persistent Memory
    140000000-1481fffff : namespace0.0
    150000000-33fffffff : �_�^7_��/_��wR��WQ���^��� ...
    150000000-33fffffff : System RAM

We have to make sure to duplicate the string.  While at it, remove the
superfluous setting of the name and fixup a stale comment.

From: David Hildenbrand <david@redhat.com>
Subject: mm/memory_hotplug: introduce add_memory_driver_managed()

Patch series "mm/memory_hotplug: Interface to add driver-managed system
ram", v4.

kexec (via kexec_load()) can currently not properly handle memory added
via dax/kmem, and will have similar issues with virtio-mem.  kexec-tools
will currently add all memory to the fixed-up initial firmware memmap.  In
case of dax/kmem, this means that - in contrast to a proper reboot - how
that persistent memory will be used can no longer be configured by the
kexec'd kernel.  In case of virtio-mem it will be harmful, because that
memory might contain inaccessible pieces that require coordination with
hypervisor first.

In both cases, we want to let the driver in the kexec'd kernel handle
detecting and adding the memory, like during an ordinary reboot. 
Introduce add_memory_driver_managed().  More on the samentics are in patch
#1.

In the future, we might want to make this behavior configurable for
dax/kmem- either by configuring it in the kernel (which would then also
allow to configure kexec_file_load()) or in kexec-tools by also adding
"System RAM (kmem)" memory from /proc/iomem to the fixed-up initial
firmware memmap.

More on the motivation can be found in [1] and [2].

[1] https://lkml.kernel.org/r/20200429160803.109056-1-david@redhat.com
[2] https://lkml.kernel.org/r/20200430102908.10107-1-david@redhat.com


This patch (of 3):

Some device drivers rely on memory they managed to not get added to the
initial (firmware) memmap as system RAM - so it's not used as initial
system RAM by the kernel and the driver is under control.  While this is
the case during cold boot and after a reboot, kexec is not aware of that
and might add such memory to the initial (firmware) memmap of the kexec
kernel.  We need ways to teach kernel and userspace that this system ram
is different.

For example, dax/kmem allows to decide at runtime if persistent memory is
to be used as system ram.  Another future user is virtio-mem, which has to
coordinate with its hypervisor to deal with inaccessible parts within
memory resources.

We want to let users in the kernel (esp. kexec) but also user space
(esp. kexec-tools) know that this memory has different semantics and
needs to be handled differently:
1. Don't create entries in /sys/firmware/memmap/
2. Name the memory resource "System RAM ($DRIVER)" (exposed via
   /proc/iomem) ($DRIVER might be "kmem", "virtio_mem").
3. Flag the memory resource IORESOURCE_MEM_DRIVER_MANAGED

/sys/firmware/memmap/ [1] represents the "raw firmware-provided memory
map" because "on most architectures that firmware-provided memory map is
modified afterwards by the kernel itself".  The primary user is kexec on
x86-64.  Since commit d96ae5309165 ("memory-hotplug: create
/sys/firmware/memmap entry for new memory"), we add all hotplugged memory
to that firmware memmap - which makes perfect sense for traditional memory
hotplug on x86-64, where real HW will also add hotplugged DIMMs to the
firmware memmap.  We replicate what the "raw firmware-provided memory map"
looks like after hot(un)plug.

To keep things simple, let the user provide the full resource name instead
of only the driver name - this way, we don't have to manually
allocate/craft strings for memory resources.  Also use the resource name
to make decisions, to avoid passing additional flags.  In case the name
isn't "System RAM", it's special.

We don't have to worry about firmware_map_remove() on the removal path. 
If there is no entry, it will simply return with -EINVAL.

We'll adapt dax/kmem in a follow-up patch.

Subject: kexec_file: don't place kexec images on IORESOURCE_MEM_DRIVER_MANAGED

Memory flagged with IORESOURCE_MEM_DRIVER_MANAGED is special - it won't be
part of the initial memmap of the kexec kernel and not all memory might be
accessible.  Don't place any kexec images onto it.

From: David Hildenbrand <david@redhat.com>
Subject: device-dax: add memory via add_memory_driver_managed()

Currently, when adding memory, we create entries in /sys/firmware/memmap/
as "System RAM".  This will lead to kexec-tools to add that memory to the
fixed-up initial memmap for a kexec kernel (loaded via kexec_load()).  The
memory will be considered initial System RAM by the kexec'd kernel and can
no longer be reconfigured.  This is not what happens during a real reboot.

Let's add our memory via add_memory_driver_managed() now, so we won't
create entries in /sys/firmware/memmap/ and indicate the memory as "System
RAM (kmem)" in /proc/iomem.  This allows everybody (especially
kexec-tools) to identify that this memory is special and has to be treated
differently than ordinary (hotplugged) System RAM.

Before configuring the namespace:
	[root@localhost ~]# cat /proc/iomem
	...
	140000000-33fffffff : Persistent Memory
	  140000000-33fffffff : namespace0.0
	3280000000-32ffffffff : PCI Bus 0000:00

After configuring the namespace:
	[root@localhost ~]# cat /proc/iomem
	...
	140000000-33fffffff : Persistent Memory
	  140000000-1481fffff : namespace0.0
	  148200000-33fffffff : dax0.0
	3280000000-32ffffffff : PCI Bus 0000:00

After loading kmem before this change:
	[root@localhost ~]# cat /proc/iomem
	...
	140000000-33fffffff : Persistent Memory
	  140000000-1481fffff : namespace0.0
	  150000000-33fffffff : dax0.0
	    150000000-33fffffff : System RAM
	3280000000-32ffffffff : PCI Bus 0000:00

After loading kmem after this change:
	[root@localhost ~]# cat /proc/iomem
	...
	140000000-33fffffff : Persistent Memory
	  140000000-1481fffff : namespace0.0
	  150000000-33fffffff : dax0.0
	    150000000-33fffffff : System RAM (kmem)
	3280000000-32ffffffff : PCI Bus 0000:00

After a proper reboot:
	[root@localhost ~]# cat /proc/iomem
	...
	140000000-33fffffff : Persistent Memory
	  140000000-1481fffff : namespace0.0
	  148200000-33fffffff : dax0.0
	3280000000-32ffffffff : PCI Bus 0000:00

	  140000000-1481fffff : namespace0.0
	  150000000-33fffffff : System RAM
	3280000000-32ffffffff : PCI Bus 0000:00

	  148200000-33fffffff : dax0.0
	3280000000-32ffffffff : PCI Bus 0000:00

/sys/firmware/memmap/ before this change:
	0000000000000000-000000000009fc00 (System RAM)

	0000000100000000-0000000140000000 (System RAM)

kexec-tools already seem to basically ignore any System RAM that's not on
top level when searching for areas to place kexec images - but also for
determining crash areas to dump via kdump.  Changing the resource name
won't have an impact.

Handle unloading of the driver after memory hotremove failed properly, by
duplicating the string if necessary.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm: shmem: remove rare optimization when swapin races with hole punching

Commit 215c02bc33bb ("tmpfs: fix shmem_getpage_gfp() VM_BUG_ON")
recognized that hole punching can race with swapin and removed the
BUG_ON() for a truncated entry from the swapin path.

The patch also added a swapcache deletion to optimize this rare case:
Since swapin has the page locked, and free_swap_and_cache() merely
trylocks, this situation can leave the page stranded in swapcache. 
Usually, page reclaim picks up stale swapcache pages, and the race can
happen at any other time when the page is locked.  (The same happens for
non-shmem swapin racing with page table zapping.) The thinking here was:
we already observed the race and we have the page locked, we may as well
do the cleanup instead of waiting for reclaim.

However, this optimization complicates the next patch which moves the
cgroup charging code around.  As this is just a minor speedup for a race
condition that is so rare that it required a fuzzer to trigger the
original BUG_ON(), it's no longer worth the complications.

[to-be-updated] kexec-prevent-removal-of-memory-in-use-by-a-loaded-kexec-image.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: kexec: prevent removal of memory in use by a loaded kexec image
has been removed from the -mm tree.  Its filename was
     kexec-prevent-removal-of-memory-in-use-by-a-loaded-kexec-image.patch

This patch was dropped because an updated version will be merged

------------------------------------------------------
From: James Morse <james.morse@arm.com>
Subject: kexec: prevent removal of memory in use by a loaded kexec image

Patch series "kexec/memory_hotplug: Prevent removal and accidental use".

arm64 recently queued support for memory hotremove, which led to some new
corner cases for kexec.

If the kexec segments are loaded for a removable region, that region may
be removed before kexec actually occurs.  This causes the first kernel to
lockup when applying the relocations.  (I've triggered this on x86 too).

The first patch adds a memory notifier for kexec so that it can refuse to
allow in-use regions to be taken offline.

This doesn't solve the problem for arm64, where the new kernel must
initially rely on the data structures from the first boot to describe
memory.  These don't describe hotpluggable memory.  If kexec places the
kernel in one of these regions, it must also provide a DT that describes
the region in which the kernel was mapped as memory.  (and somehow ensure
its always present in the future...)

To prevent this from happening accidentally with unaware user-space,
patches two and three allow arm64 to give these regions a different name.

This is a change in behaviour for arm64 as memory hotadd and hotremove
were added separately.

I haven't tried kdump.  Unaware kdump from user-space probably won't
describe the hotplug regions if the name is different, which saves us from
problems if the memory is no longer present at kdump time, but means the
vmcore is incomplete.


This patch (of 3):

An image loaded for kexec is not stored in place, instead its segments are
scattered through memory, and are re-assembled when needed.  In the
meantime, the target memory may have been removed.

Because mm is not aware that this memory is still in use, it allows it
to be removed.

Add a memory notifier to prevent the removal of memory regions that
overlap with a loaded kexec image segment.  e.g., when triggered from the
Qemu console:

| kexec_core: memory region in use
| memory memory32: Offline failed.

Kexec allows user-space to specify the address that the kexec image
should be loaded to.  Because this memory may be in use, an image
loaded for kexec is not stored in place, instead its segments are
scattered through memory, and are re-assembled when needed.  In the
meantime, the target memory may have been removed.

The target is described by user space during kexec_load() and that user
space - right now - parses /proc/iomem to find applicable system
memory.

From: James Morse <james.morse@arm.com>
Subject: mm/memory_hotplug: allow arch override of non boot memory resource names

Memory added to the system by hotplug has a 'System RAM' resource created
for it.  This is exposed to user-space via /proc/iomem.

This poses problems for kexec on arm64.  If kexec decides to place the
kernel in one of these newly onlined regions, the new kernel will find
itself booting from a region not described as memory in the firmware
tables.

Arm64 doesn't have a structure like the e820 memory map that can be
re-written when memory is brought online.  Instead arm64 uses the UEFI
memory map, or the memory node from the DT, sometimes both.  We never
rewrite these.

Allow an architecture to specify a different name for these hotplug
regions.

If kexec chooses to place the kernel in a memory region that was added
after boot, we fail to boot as the kernel is running from a location that
is not described as memory by the UEFI memory map or the original DT.

To prevent unaware user-space kexec from doing this accidentally, give
these regions a different name.

From: Anshuman Khandual <anshuman.khandual@arm.com>
Subject: arm64/mm: drop __HAVE_ARCH_HUGE_PTEP_GET

Patch series "mm/hugetlb: Add some new generic fallbacks", v3.

This series adds the following new generic fallbacks.  Before that it
drops __HAVE_ARCH_HUGE_PTEP_GET from arm64 platform.

1. is_hugepage_only_range()
2. arch_clear_hugepage_flags()

After this arm (32 bit) remains the sole platform defining it's own
huge_ptep_get() via __HAVE_ARCH_HUGE_PTEP_GET.


This patch (of 3):

Platform specific huge_ptep_get() is required only when fetching the huge
PTE involves more than just dereferencing the page table pointer.  This is
not the case on arm64 platform.  Hence huge_ptep_pte() can be dropped
along with it's __HAVE_ARCH_HUGE_PTEP_GET subscription.  Before that, it
updates the generic huge_ptep_get() with READ_ONCE() which will prevent
known page table issues with THP on arm64.

There are multiple similar definitions for is_hugepage_only_range() on

platforms that do not override.  This help reduce code duplication.

Subject: mm/hugetlb: define a generic fallback for arch_clear_hugepage_flags()

There are multiple similar definitions for arch_clear_hugepage_flags() on
various platforms.  Lets just add it's generic fallback definition for
platforms that do not override.  This help reduce code duplication.

[alternative-merged] mm-vmscan-consistent-update-to-pgsteal-and-pgscan.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: mm: vmscan: consistent update to pgsteal and pgscan
has been removed from the -mm tree.  Its filename was
     mm-vmscan-consistent-update-to-pgsteal-and-pgscan.patch

This patch was dropped because an alternative patch was merged

------------------------------------------------------
From: Shakeel Butt <shakeelb@google.com>
Subject: mm: vmscan: consistent update to pgsteal and pgscan

One way to measure the efficiency of memory reclaim is to look at the
ratio (pgscan+pfrefill)/pgsteal.  However at the moment these stats are
not updated consistently at the system level and the ratio of these are
not very meaningful.  The pgsteal and pgscan are updated for only global
reclaim while pgrefill gets updated for global as well as cgroup reclaim.

Please note that this difference is only for system level vmstats.  The
cgroup stats returned by memory.stat are actually consistent.  The
cgroup's pgsteal contains number of reclaimed pages for global as well as
cgroup reclaim.  So, one way to get the system level stats is to get these
stats from root's memory.stat but root does not expose that interface. 
Also for !CONFIG_MEMCG machines /proc/vmstat is the only way to get these
stats.  So, make these stats consistent.

From: Kefeng Wang <wangkefeng.wang@huawei.com>
Subject: include/linux/seq_file.h: introduce DEFINE_SEQ_ATTRIBUTE() helper macro

Patch series "seq_file: Introduce DEFINE_SEQ_ATTRIBUTE() helper macro".

As discussed in
https://lore.kernel.org/lkml/20191129222310.GA3712618@kroah.com/, we could
introduce a new helper macro to reduce losts of boilerplate code, vmstat
and kprobes is the example which covert to use it, if this is accepted, I
will send out more cleanups.


This patch (of 3):

Introduce DEFINE_SEQ_ATTRIBUTE() helper macro to decrease code duplication.

From: Tan Hu <tan.hu@zte.com.cn>
Subject: lib/flex_proportions.c: cleanup __fprop_inc_percpu_max

If the given type has fraction smaller than max_frac/FPROP_FRAC_BASE, the
code could be modified to call __fprop_inc_percpu() directly and easier to
understand.  After this patch, fprop_reflect_period_percpu() will be
called twice, and quicky return on pl->period == p->period test, so it
would not result to significant downside of performance.

Thanks for Jan's guidance.

mmotm 2020-05-11-15-43 uploaded

[Andrew Morton]

The mm-of-the-moment snapshot 2020-05-11-15-43 has been uploaded to

   http://www.ozlabs.org/~akpm/mmotm/

mmotm-readme.txt says

README for mm-of-the-moment:

http://www.ozlabs.org/~akpm/mmotm/

This is a snapshot of my -mm patch queue.  Uploaded at random hopefully
more than once a week.

You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY).  The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss.  Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.

This tree is partially included in linux-next.  To see which patches are
included in linux-next, consult the `series' file.  Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.


A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release.  Individual mmotm releases are tagged.  The master branch always
points to the latest release, so it's constantly rebasing.

	https://github.com/hnaz/linux-mm

The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree.  It is updated more frequently
than mmotm, and is untested.

A git copy of this tree is also available at

	https://github.com/hnaz/linux-mm

The THP page size macros are CONFIG_TRANSPARENT_HUGEPAGE only.

We already ifdef most THP-related code in memcg, but not these
particular stats. Memcg used to track the pages as they came in, and
PageTransHuge() + hpage_nr_pages() work when THP is not compiled in.

Switching to native vmstat counters, memcg doesn't see the pages, it
only gets a count of THPs. To translate that to bytes, it has to know
how big the THPs are - and that's only available for CONFIG_THP.

Add the necessary ifdefs. /proc/meminfo, smaps etc. also don't show
the THP counters when the feature is compiled out. The event counts
(THP_FAULT_ALLOC, THP_COLLAPSE_ALLOC) were already conditional also.

Style touchup: HPAGE_PMD_NR * PAGE_SIZE is silly. Use HPAGE_PMD_SIZE.

Fixes the build issue with m68k/allmodconfig, too.
Not boot-tested.

From: Andrey Konovalov <andreyknvl@google.com>
Subject: kasan: consistently disable debugging features

KASAN is incompatible with some kernel debugging/tracing features. 
There's been multiple patches that disable those feature for some of KASAN
files one by one.  Instead of prolonging that, disable these features for
all KASAN files at once.

KASAN is currently missing declarations for __asan_report* and __hwasan*
functions.  This can lead to compiler warnings.

From: Konstantin Khlebnikov <khlebnikov@yandex-team.ru>
Subject: mm/compaction: avoid VM_BUG_ON(PageSlab()) in page_mapcount()

isolate_migratepages_block() runs some checks out of lru_lock when
choosing pages for migration.  After checking PageLRU() it checks extra
page references by comparing page_count() and page_mapcount().  Between
these two checks page could be removed from lru, freed and taken by slab.

As a result this race triggers VM_BUG_ON(PageSlab()) in page_mapcount(). 
Race window is tiny.  For certain workload this happens around once a
year.

Subject: kernel/sysctl.c: ignore out-of-range taint bits introduced via kernel.tainted

Users with SYS_ADMIN capability can add arbitrary taint flags to the
running kernel by writing to /proc/sys/kernel/tainted or issuing the
command 'sysctl -w kernel.tainted=...'.  This interface, however, is open
for any integer value and this might cause an invalid set of flags being
committed to the tainted_mask bitset.

This patch introduces a simple way for proc_taint() to ignore any eventual
invalid bit coming from the user input before committing those bits to the
kernel tainted_mask.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: Re: vfs: keep inodes with page cache off the inode shrinker LRU

The VFS inode shrinker is currently allowed to reclaim cold inodes with
populated page cache.  This behavior goes back to CONFIG_HIGHMEM setups,
which required the ability to drop page cache in large highem zones to
free up struct inodes in comparatively tiny lowmem zones.

However, it has significant side effects that are hard to justify on
systems without highmem:

- It can drop gigabytes of hot and active page cache on the floor
  without consulting the VM (recorded as "inodesteal" events in
  /proc/vmstat).  Such an "aging inversion" between unreferenced inodes
  holding hot cache easily happens in practice: for example, a git tree
  whose objects are accessed frequently but no open file descriptors are
  maintained throughout.

- It can als prematurely drop non-resident info stored inside the
  inodes, which can let massive cache thrashing go unnoticed.  This in
  turn means we're making the wrong decisions in page reclaim and can get
  stuck in pathological thrashing.  The thrashing also doesn't show up as
  memory pressure in psi, causing failure in the userspace OOM detection
  chain, which can leave a system (or Android device e.g.) stranded in a
  livelock.

History

As this keeps causing problems for people, there have been several
attempts to address this.

One recent attempt was to make the inode shrinker simply skip over inodes
that still contain pages: a76cf1a474d7 ("mm: don't reclaim inodes with
many attached pages").

However, this change had to be reverted in 69056ee6a8a3 ("Revert "mm:
don't reclaim inodes with many attached pages"") because it caused severe
reclaim performance problems: Inodes that sit on the shrinker LRU are
attracting reclaim pressure away from the page cache and toward the VFS. 
If we then permanently exempt sizable portions of this pool from actually
getting reclaimed when looked at, this pressure accumulates as deferred
shrinker work (a mechanism for *temporarily* unreclaimable objects) until
it causes mayhem in the VFS cache pools.

In the bug quoted in 69056ee6a8a3 in particular, the excessive pressure
drove the XFS shrinker into dirty objects, where it caused synchronous,
IO-bound stalls, even as there was plenty of clean page cache that should
have been reclaimed instead.

Another variant of this problem was recently observed, where the kernel
violates cgroups' memory.low protection settings and reclaims page cache
way beyond the configured thresholds.  It was followed by a proposal of a
modified form of the reverted commit above, that implements
memory.low-sensitive shrinker skipping over populated inodes on the LRU
[1].  However, this proposal continues to run the risk of attracting
disproportionate reclaim pressure to a pool of still-used inodes, while
not addressing the more generic reclaim inversion problem outside of a
very specific cgroup application.

[1] https://lore.kernel.org/linux-mm/1578499437-1664-1-git-send-email-laoar.shao@gmail.com/

Solution

This patch fixes the aging inversion described above on !CONFIG_HIGHMEM
systems, without reintroducing the problems associated with excessive
shrinker LRU rotations, by keeping populated inodes off the shrinker LRUs
entirely.

Currently, inodes are kept off the shrinker LRU as long as they have an
elevated i_count, indicating an active user.  Unfortunately, the page
cache cannot simply hold an i_count reference, because unlink() *should*
result in the inode being dropped and its cache invalidated.

Instead, this patch makes iput_final() consult the state of the page cache
and punt the LRU linking to the VM if the inode is still populated; the VM
in turn checks the inode state when it depopulates the page cache, and
adds the inode to the LRU if necessary.

This is not unlike what we do for dirty inodes, which are moved off the
LRU permanently until writeback completion puts them back on (iff still
unused).  We can reuse the same code -- inode_add_lru() - here.

This is also not unlike page reclaim, where the lower VM layer has to
negotiate state with the higher VFS layer.  Follow existing precedence and
handle the inversion as much as possible on the VM side:

- introduce an I_PAGES flag that the VM maintains under the i_lock, so
  that any inode code holding that lock can check the page cache state
  without having to lock and inspect the struct address_space

- introduce inode_pages_set() and inode_pages_clear() to maintain the
  inode LRU state from the VM side, then update all cache mutators to use
  them when populating the first cache entry or clearing the last

With this, the concept of "inodesteal" - where the inode shrinker drops
page cache - is relegated to CONFIG_HIGHMEM systems only.  The VM is in
charge of the cache, the shrinker in charge of struct inode.

Footnotes

- For debuggability, add vmstat counters that track the number of times
  a new cache entry pulls a previously unused inode off the LRU
  (pginoderescue), as well as how many times existing cache deferred an
  LRU addition.  Keep the pginodesteal/kswapd_inodesteal counters for
  backwards compatibility, but they'll just show 0 now.

- Fix /proc/sys/vm/drop_caches to drop shadow entries from the page
  cache.  Not doing so has always been a bit strange, but since most
  people drop cache and metadata cache together, the inode shrinker would
  have taken care of them before - no more, so do it VM-side.

Fix crash.  If you have CONFIG_NUMA and the allocation fails, *hpage could
contain an ERR_PTR instead of being NULL.

From: Johannes Weiner <hannes@cmpxchg.org>
Subject: mm-memcontrol-switch-to-native-nr_anon_thps-counter-fix

The THP page size macros are CONFIG_TRANSPARENT_HUGEPAGE only.

We already ifdef most THP-related code in memcg, but not these
particular stats. Memcg used to track the pages as they came in, and
PageTransHuge() + hpage_nr_pages() work when THP is not compiled in.

Switching to native vmstat counters, memcg doesn't see the pages, it
only gets a count of THPs. To translate that to bytes, it has to know
how big the THPs are - and that's only available for CONFIG_THP.

Add the necessary ifdefs. /proc/meminfo, smaps etc. also don't show
the THP counters when the feature is compiled out. The event counts
(THP_FAULT_ALLOC, THP_COLLAPSE_ALLOC) were already conditional also.

Style touchup: HPAGE_PMD_NR * PAGE_SIZE is silly. Use HPAGE_PMD_SIZE.
