Alistair Popple 6292503700 mm/hmm.c: allow VM_MIXEDMAP to work with hmm_range_fault
commit 87c01d57fa23de82fff593a7d070933d08755801 upstream.

hmm_range_fault() can be used instead of get_user_pages() for devices
which allow faulting however unlike get_user_pages() it will return an
error when used on a VM_MIXEDMAP range.

To make hmm_range_fault() more closely match get_user_pages() remove
this restriction.  This requires dealing with the !ARCH_HAS_PTE_SPECIAL
case in hmm_vma_handle_pte().  Rather than replicating the logic of
vm_normal_page() call it directly and do a check for the zero pfn
similar to what get_user_pages() currently does.

Also add a test to hmm selftest to verify functionality.

Gang Li 7b9fa915a5 shmem: fix a race between shmem_unused_huge_shrink and shmem_evict_inode
commit 62c9827cbb996c2c04f615ecd783ce28bcea894b upstream.

Fix a data race in commit 779750d20b ("shmem: split huge pages beyond
i_size under memory pressure").

Here are call traces causing race:

   Call Trace 1:
     shmem_unused_huge_shrink+0x3ae/0x410
     ? __list_lru_walk_one.isra.5+0x33/0x160

     ? kthread_create_on_node+0x70/0x70
     ret_from_fork+0x1f/0x30

   Call Trace 2:
     shmem_evict_inode+0xd8/0x190
     evict+0xbe/0x1c0
     do_unlinkat+0x137/0x330
     do_syscall_64+0x76/0x120
     entry_SYSCALL_64_after_hwframe+0x3d/0xa2

A simple explanation:

Image there are 3 items in the local list (@list).  In the first
traversal, A is not deleted from @list.

  1)    A->B->C
        ^
        |
        pos (leave)

In the second traversal, B is deleted from @list.  Concurrently, A is
deleted from @list through shmem_evict_inode() since last reference
counter of inode is dropped by other thread.  Then the @list is corrupted.

  2)    A->B->C
        ^  ^
        |  |
     evict pos (drop)

We should make sure the inode is either on the global list or deleted from
any local list before iput().

Fixed by moving inodes back to global list before we put them.

Baoquan He 6c6f86bb61 mm/page_alloc.c: do not warn allocation failure on zone DMA if no managed pages
commit c4dc63f0032c77464fbd4e7a6afc22fa6913c4a7 upstream.

In kdump kernel of x86_64, page allocation failure is observed:

The above failure happened when calling kmalloc() to allocate buffer with
GFP_DMA.  It requests to allocate slab page from DMA zone while no managed
pages at all in there.

 sr_probe()
 --> get_capabilities()
     --> buffer = kmalloc(512, GFP_KERNEL | GFP_DMA);

Because in the current kernel, dma-kmalloc will be created as long as
CONFIG_ZONE_DMA is enabled.  However, kdump kernel of x86_64 doesn't have
managed pages on DMA zone since commit 6f599d8423 ("x86/kdump: Always
reserve the low 1M when the crashkernel option is specified").  The
failure can be always reproduced.

For now, let's mute the warning of allocation failure if requesting pages
from DMA zone while no managed pages.

Baoquan He d2e5724117 mm_zone: add function to check if managed dma zone exists
commit 62b3107073646e0946bd97ff926832bafb846d17 upstream.

Patch series "Handle warning of allocation failure on DMA zone w/o
managed pages", v4.

**Problem observed:
On x86_64, when crash is triggered and entering into kdump kernel, page
allocation failure can always be seen.

 Mem-Info:
 ------------------------------------

***Root cause:
In the current kernel, it assumes that DMA zone must have managed pages
and try to request pages if CONFIG_ZONE_DMA is enabled. While this is not
always true. E.g in kdump kernel of x86_64, only low 1M is presented and
locked down at very early stage of boot, so that this low 1M won't be
added into buddy allocator to become managed pages of DMA zone. This
exception will always cause page allocation failure if page is requested
from DMA zone.

***Investigation:
This failure happens since below commit merged into linus's tree.
  1a6a9044b967 x86/setup: Remove CONFIG_X86_RESERVE_LOW and reservelow= options
  23721c8e92f7 x86/crash: Remove crash_reserve_low_1M()
  f1d4d47c5851 x86/setup: Always reserve the first 1M of RAM
  7c321eb2b8 x86/kdump: Remove the backup region handling
  6f599d8423 x86/kdump: Always reserve the low 1M when the crashkernel option is specified

Before them, on x86_64, the low 640K area will be reused by kdump kernel.
So in kdump kernel, the content of low 640K area is copied into a backup
region for dumping before jumping into kdump. Then except of those firmware
reserved region in [0, 640K], the left area will be added into buddy
allocator to become available managed pages of DMA zone.

However, after above commits applied, in kdump kernel of x86_64, the low
1M is reserved by memblock, but not released to buddy allocator. So any
later page allocation requested from DMA zone will fail.

At the beginning, if crashkernel is reserved, the low 1M need be locked
down because AMD SME encrypts memory making the old backup region
mechanims impossible when switching into kdump kernel.

Later, it was also observed that there are BIOSes corrupting memory
under 1M. To solve this, in commit f1d4d47c5851, the entire region of
low 1M is always reserved after the real mode trampoline is allocated.

Besides, recently, Intel engineer mentioned their TDX (Trusted domain
extensions) which is under development in kernel also needs to lock down
the low 1M. So we can't simply revert above commits to fix the page allocation
failure from DMA zone as someone suggested.

***Solution:
Currently, only DMA atomic pool and dma-kmalloc will initialize and
request page allocation with GFP_DMA during bootup.

So only initializ DMA atomic pool when DMA zone has available managed
pages, otherwise just skip the initialization.

For dma-kmalloc(), for the time being, let's mute the warning of
allocation failure if requesting pages from DMA zone while no manged
pages.  Meanwhile, change code to use dma_alloc_xx/dma_map_xx API to
replace kmalloc(GFP_DMA), or do not use GFP_DMA when calling kmalloc() if
not necessary.  Christoph is posting patches to fix those under
drivers/scsi/.  Finally, we can remove the need of dma-kmalloc() as people
suggested.

This patch (of 3):

In some places of the current kernel, it assumes that dma zone must have
managed pages if CONFIG_ZONE_DMA is enabled.  While this is not always
true.  E.g in kdump kernel of x86_64, only low 1M is presented and locked
down at very early stage of boot, so that there's no managed pages at all
in DMA zone.  This exception will always cause page allocation failure if
page is requested from DMA zone.

Here add function has_managed_dma() and the relevant helper functions to
check if there's DMA zone with managed pages.  It will be used in later
patches.

Suren Baghdasaryan f4f2c619d5 FROMLIST: mm/oom_kill: allow process_mrelease to run under mmap_lock protection
With exit_mmap holding mmap_write_lock during free_pgtables call,
process_mrelease does not need to elevate mm->mm_users in order to
prevent exit_mmap from destrying pagetables while __oom_reap_task_mm
is walking the VMA tree. The change prevents process_mrelease from
calling the last mmput, which can lead to waiting for IO completion
in exit_aio.

Suren Baghdasaryan 2452622293 FROMLIST: mm: protect free_pgtables with mmap_lock write lock in exit_mmap
oom-reaper and process_mrelease system call should protect against
races with exit_mmap which can destroy page tables while they
walk the VMA tree. oom-reaper protects from that race by setting
MMF_OOM_VICTIM and by relying on exit_mmap to set MMF_OOM_SKIP
before taking and releasing mmap_write_lock. process_mrelease has
to elevate mm->mm_users to prevent such race. Both oom-reaper and
process_mrelease hold mmap_read_lock when walking the VMA tree.
The locking rules and mechanisms could be simpler if exit_mmap takes
mmap_write_lock while executing destructive operations such as
free_pgtables.
Change exit_mmap to hold the mmap_write_lock when calling
free_pgtables. Operations like unmap_vmas() and unlock_range() are not
destructive and could run under mmap_read_lock but for simplicity we
take one mmap_write_lock during almost the entire operation. Note
also that because oom-reaper checks VM_LOCKED flag, unlock_range()
should not be allowed to race with it.
In most cases this lock should be uncontended. Previously, Kirill
reported ~4% regression caused by a similar change [1]. We reran the
same test and although the individual results are quite noisy, the
percentiles show lower regression with 1.6% being the worst case [2].
The change allows oom-reaper and process_mrelease to execute safely
under mmap_read_lock without worries that exit_mmap might destroy page
tables from under them.

Suren Baghdasaryan fd7af95538 UPSTREAM: mm/oom_kill.c: prevent a race between process_mrelease and exit_mmap
Race between process_mrelease and exit_mmap, where free_pgtables is
called while __oom_reap_task_mm is in progress, leads to kernel crash
during pte_offset_map_lock call.  oom-reaper avoids this race by setting
MMF_OOM_VICTIM flag and causing exit_mmap to take and release
mmap_write_lock, blocking it until oom-reaper releases mmap_read_lock.

Reusing MMF_OOM_VICTIM for process_mrelease would be the simplest way to
fix this race, however that would be considered a hack.  Fix this race
by elevating mm->mm_users and preventing exit_mmap from executing until
process_mrelease is finished.  Patch slightly refactors the code to
adapt for a possible mmget_not_zero failure.

This fix has considerable negative impact on process_mrelease
performance and will likely need later optimization.

Suren Baghdasaryan 7fc3ac4968 UPSTREAM: mm: introduce process_mrelease system call
In modern systems it's not unusual to have a system component monitoring
memory conditions of the system and tasked with keeping system memory
pressure under control.  One way to accomplish that is to kill
non-essential processes to free up memory for more important ones.
Examples of this are Facebook's OOM killer daemon called oomd and
Android's low memory killer daemon called lmkd.

For such system component it's important to be able to free memory quickly
and efficiently.  Unfortunately the time process takes to free up its
memory after receiving a SIGKILL might vary based on the state of the
process (uninterruptible sleep), size and OPP level of the core the
process is running.  A mechanism to free resources of the target process
in a more predictable way would improve system's ability to control its
memory pressure.

Introduce process_mrelease system call that releases memory of a dying
process from the context of the caller.  This way the memory is freed in a
more controllable way with CPU affinity and priority of the caller.  The
workload of freeing the memory will also be charged to the caller.  The
operation is allowed only on a dying process.

After previous discussions [1, 2, 3] the decision was made [4] to
introduce a dedicated system call to cover this use case.

The API is as follows,

          int process_mrelease(int pidfd, unsigned int flags);

        DESCRIPTION
          The process_mrelease() system call is used to free the memory of
          an exiting process.

          The pidfd selects the process referred to by the PID file
          descriptor.
          (See pidfd_open(2) for further information)

          The flags argument is reserved for future use; currently, this
          argument must be specified as 0.

        RETURN VALUE
          On success, process_mrelease() returns 0. On error, -1 is
          returned and errno is set to indicate the error.

        ERRORS
          EBADF  pidfd is not a valid PID file descriptor.

          EAGAIN Failed to release part of the address space.

          EINTR  The call was interrupted by a signal; see signal(7).

          EINVAL flags is not 0.

          EINVAL The memory of the task cannot be released because the
                 process is not exiting, the address space is shared
                 with another live process or there is a core dump in
                 progress.

          ENOSYS This system call is not supported, for example, without
                 MMU support built into Linux.

          ESRCH  The target process does not exist (i.e., it has terminated
                 and been waited on).

Andrey Ryabinin ee6f34215c mm: mempolicy: fix THP allocations escaping mempolicy restrictions
commit 338635340669d5b317c7e8dcf4fff4a0f3651d87 upstream.

alloc_pages_vma() may try to allocate THP page on the local NUMA node
first:

	page = __alloc_pages_node(hpage_node,
		gfp | __GFP_THISNODE | __GFP_NORETRY, order);

And if the allocation fails it retries allowing remote memory:

	if (!page && (gfp & __GFP_DIRECT_RECLAIM))
    		page = __alloc_pages_node(hpage_node,
					gfp, order);

However, this retry allocation completely ignores memory policy nodemask
allowing allocation to escape restrictions.

The first appearance of this bug seems to be the commit ac5b2c1891
("mm: thp: relax __GFP_THISNODE for MADV_HUGEPAGE mappings").

The bug disappeared later in the commit 89c83fb539 ("mm, thp:
consolidate THP gfp handling into alloc_hugepage_direct_gfpmask") and
reappeared again in slightly different form in the commit 76e654cc91
("mm, page_alloc: allow hugepage fallback to remote nodes when
madvised")

Fix this by passing correct nodemask to the __alloc_pages() call.

The demonstration/reproducer of the problem:

Liu Shixin 1f20707674 mm/hwpoison: clear MF_COUNT_INCREASED before retrying get_any_page()
commit 2a57d83c78f889bf3f54eede908d0643c40d5418 upstream.

Hulk Robot reported a panic in put_page_testzero() when testing
madvise() with MADV_SOFT_OFFLINE.  The BUG() is triggered when retrying
get_any_page().  This is because we keep MF_COUNT_INCREASED flag in
second try but the refcnt is not increased.

    page dumped because: VM_BUG_ON_PAGE(page_ref_count(page) == 0)

Mike Rapoport 6e634c0e71 memblock: ensure there is no overflow in memblock_overlaps_region()
[ Upstream commit 023accf5cdc1e504a9b04187ec23ff156fe53d90 ]

There maybe an overflow in memblock_overlaps_region() if it is called with
base and size such that

	base + size > PHYS_ADDR_MAX

Make sure that memblock_overlaps_region() caps the size to prevent such
overflow and remove now duplicated call to memblock_cap_size() from
memblock_is_region_reserved().

Suren Baghdasaryan 5d8520b557 ANDROID: fix ABI breakage caused by mm_struct->mmu_notifier_lock addition
To prevent ABI breakage, move mm->mmu_notifier_lock into
mm->notifier_subscriptions and allocate mm->notifier_subscriptions
during mm creation in mmu_notifier_subscriptions_init. This results
in additional 176 bytes allocated for each mm, but prevents ABI breakage.
mmu_notifier_subscriptions_hdr structure is introduced at the beginning
of mmu_notifier_subscriptions to keep mmu_notifier_subscriptions hidden
and prevent its type CRC from changing when used in other structures.

Suren Baghdasaryan a4d26b9a4b ANDROID: fix ABI breakage caused by percpu_rw_semaphore changes
percpu_rw_semaphore changes to allow calling percpu_free_rwsem in atomic
context cause ABI breakage. Introduce percpu_free_rwsem_atomic wrapper
and change percpu_rwsem_destroy to use it in order to keep
percpu_rw_semaphore struct intact and fix ABI breakage.

Suren Baghdasaryan 6971350406 ANDROID: fix mmu_notifier race caused by not taking mmap_lock during SPF
When pagefaults are handled speculatively,the pair of
mmu_notifier_invalidate_range_start/mmu_notifier_invalidate_range_end
calls happen without mmap_lock being taken. This enables the following
race:

mmu_notifier_invalidate_range_start
                                       mmap_write_lock
                                       mmu_notifier_register
                                       mmap_write_unlock
mmu_notifier_invalidate_range_end

In this case mmu_notifier_invalidate_range_end will see a new
subscriber not seen at the time of mmu_notifier_invalidate_range_start
and will call ops->invalidate_range_end for that subscriber without
the matching ops->invalidate_range_start, creating imbalance.
Fix this by introducing a new mm->mmu_notifier_lock percpu_rw_semaphore
to synchronize mmu_notifier_invalidate_range_start/
mmu_notifier_invalidate_range_end with mmu_notifier_register when
handling pagefaults speculatively without holding mmap_lock.
percpu_rw_semaphore is used instead of rw_semaphore to prevent cache
line bouncing in the pagefault path.

Miaohe Lin 6b6725f77d UPSTREAM: mm, slub: fix two bugs in slab_debug_trace_open()
Patch series "Fixups for slub".

This series contains various bug fixes for slub.  We fix memoryleak,
use-afer-free, NULL pointer dereferencing and so on in slub.  More
details can be found in the respective changelogs.

This patch (of 5):

It's possible that __seq_open_private() will return NULL.  So we should
check it before using lest dereferencing NULL pointer.  And in error
paths, we forgot to release private buffer via seq_release_private().
Memory will leak in these paths.

Vlastimil Babka 791f85d16d UPSTREAM: mm, slub: allocate private object map for debugfs listings
Slub has a static spinlock protected bitmap for marking which objects are on
freelist when it wants to list them, for situations where dynamically
allocating such map can lead to recursion or locking issues, and on-stack
bitmap would be too large.

The handlers of debugfs files alloc_traces and free_traces also currently use this
shared bitmap, but their syscall context makes it straightforward to allocate a
private map before entering locked sections, so switch these processing paths
to use a private bitmap.

Patrick Daly f37b6d79f8 ANDROID: mm/memory_hotplug: Don't special case memory_block_size_bytes
If add_memory_subsection() is called with a size of
memory_block_size_bytes, it calls into add_memory(), which declares
the region as system ram, and adds it to the buddy allocator. This
is inconsistent with the behavior of add_memory_subsection() for
other sizes, for which it does not add the memory to buddy and
instead reserves it for the caller's private use.

Manjong Lee c581090228 mm: bdi: initialize bdi_min_ratio when bdi is unregistered
commit 3c376dfafbf7a8ea0dea212d095ddd83e93280bb upstream.

Initialize min_ratio if it is set during bdi unregistration.  This can
prevent problems that may occur a when bdi is removed without resetting
min_ratio.

For example.
1) insert external sdcard
2) set external sdcard's min_ratio 70
3) remove external sdcard without setting min_ratio 0
4) insert external sdcard
5) set external sdcard's min_ratio 70 << error occur(can't set)

Because when an sdcard is removed, the present bdi_min_ratio value will
remain.  Currently, the only way to reset bdi_min_ratio is to reboot.

Jason Gunthorpe 78ea29e570 UPSTREAM: mm/gup: remove the vma allocation from gup_longterm_locked()
Long ago there wasn't a FOLL_LONGTERM flag so this DAX check was done by
post-processing the VMA list.

These days it is trivial to just check each VMA to see if it is DAX before
processing it inside __get_user_pages() and return failure if a DAX VMA is
encountered with FOLL_LONGTERM.

Removing the allocation of the VMA list is a significant speed up for many
call sites.

Add an IS_ENABLED to vma_is_fsdax so that code generation is unchanged
when DAX is compiled out.

Remove the dummy version of __gup_longterm_locked() as !CONFIG_CMA already
makes memalloc_nocma_save(), check_and_migrate_cma_pages(), and
memalloc_nocma_restore() into a NOP.

Nadav Amit 40bc831ab5 hugetlbfs: flush TLBs correctly after huge_pmd_unshare
commit a4a118f2eead1d6c49e00765de89878288d4b890 upstream.

When __unmap_hugepage_range() calls to huge_pmd_unshare() succeed, a TLB
flush is missing.  This TLB flush must be performed before releasing the
i_mmap_rwsem, in order to prevent an unshared PMDs page from being
released and reused before the TLB flush took place.

Arguably, a comprehensive solution would use mmu_gather interface to
batch the TLB flushes and the PMDs page release, however it is not an
easy solution: (1) try_to_unmap_one() and try_to_migrate_one() also call
huge_pmd_unshare() and they cannot use the mmu_gather interface; and (2)
deferring the release of the page reference for the PMDs page until
after i_mmap_rwsem is dropeed can confuse huge_pmd_unshare() into
thinking PMDs are shared when they are not.

Fix __unmap_hugepage_range() by adding the missing TLB flush, and
forcing a flush when unshare is successful.

Rustam Kovhaev b2e2fb6407 mm: kmemleak: slob: respect SLAB_NOLEAKTRACE flag
commit 34dbc3aaf5d9e89ba6cc5e24add9458c21ab1950 upstream.

When kmemleak is enabled for SLOB, system does not boot and does not
print anything to the console.  At the very early stage in the boot
process we hit infinite recursion from kmemleak_init() and eventually
kernel crashes.

kmemleak_init() specifies SLAB_NOLEAKTRACE for KMEM_CACHE(), but
kmem_cache_create_usercopy() removes it because CACHE_CREATE_MASK is not
valid for SLOB.

Let's fix CACHE_CREATE_MASK and make kmemleak work with SLOB

Michal Hocko 1d45798736 mm, oom: do not trigger out_of_memory from the #PF
commit 60e2793d440a3ec95abb5d6d4fc034a4b480472d upstream.

Any allocation failure during the #PF path will return with VM_FAULT_OOM
which in turn results in pagefault_out_of_memory.  This can happen for 2
different reasons.  a) Memcg is out of memory and we rely on
mem_cgroup_oom_synchronize to perform the memcg OOM handling or b)
normal allocation fails.

The latter is quite problematic because allocation paths already trigger
out_of_memory and the page allocator tries really hard to not fail
allocations.  Anyway, if the OOM killer has been already invoked there
is no reason to invoke it again from the #PF path.  Especially when the
OOM condition might be gone by that time and we have no way to find out
other than allocate.

Moreover if the allocation failed and the OOM killer hasn't been invoked
then we are unlikely to do the right thing from the #PF context because
we have already lost the allocation context and restictions and
therefore might oom kill a task from a different NUMA domain.

This all suggests that there is no legitimate reason to trigger
out_of_memory from pagefault_out_of_memory so drop it.  Just to be sure
that no #PF path returns with VM_FAULT_OOM without allocation print a
warning that this is happening before we restart the #PF.

[VvS: #PF allocation can hit into limit of cgroup v1 kmem controller.
This is a local problem related to memcg, however, it causes unnecessary
global OOM kills that are repeated over and over again and escalate into a
real disaster.  This has been broken since kmem accounting has been
introduced for cgroup v1 (3.8).  There was no kmem specific reclaim for
the separate limit so the only way to handle kmem hard limit was to return
with ENOMEM.  In upstream the problem will be fixed by removing the
outdated kmem limit, however stable and LTS kernels cannot do it and are
still affected.  This patch fixes the problem and should be backported
into stable/LTS.]

Vasily Averin ac7f6befc3 mm, oom: pagefault_out_of_memory: don't force global OOM for dying tasks
commit 0b28179a6138a5edd9d82ad2687c05b3773c387b upstream.

Patch series "memcg: prohibit unconditional exceeding the limit of dying tasks", v3.

Memory cgroup charging allows killed or exiting tasks to exceed the hard
limit.  It can be misused and allowed to trigger global OOM from inside
a memcg-limited container.  On the other hand if memcg fails allocation,
called from inside #PF handler it triggers global OOM from inside
pagefault_out_of_memory().

To prevent these problems this patchset:
 (a) removes execution of out_of_memory() from
     pagefault_out_of_memory(), becasue nobody can explain why it is
     necessary.
 (b) allow memcg to fail allocation of dying/killed tasks.

This patch (of 3):

Any allocation failure during the #PF path will return with VM_FAULT_OOM
which in turn results in pagefault_out_of_memory which in turn executes
out_out_memory() and can kill a random task.

An allocation might fail when the current task is the oom victim and
there are no memory reserves left.  The OOM killer is already handled at
the page allocator level for the global OOM and at the charging level
for the memcg one.  Both have much more information about the scope of
allocation/charge request.  This means that either the OOM killer has
been invoked properly and didn't lead to the allocation success or it
has been skipped because it couldn't have been invoked.  In both cases
triggering it from here is pointless and even harmful.

It makes much more sense to let the killed task die rather than to wake
up an eternally hungry oom-killer and send him to choose a fatter victim
for breakfast.

Vasily Averin 74293225f5 memcg: prohibit unconditional exceeding the limit of dying tasks
commit a4ebf1b6ca1e011289677239a2a361fde4a88076 upstream.

Memory cgroup charging allows killed or exiting tasks to exceed the hard
limit.  It is assumed that the amount of the memory charged by those
tasks is bound and most of the memory will get released while the task
is exiting.  This is resembling a heuristic for the global OOM situation
when tasks get access to memory reserves.  There is no global memory
shortage at the memcg level so the memcg heuristic is more relieved.

The above assumption is overly optimistic though.  E.g.  vmalloc can
scale to really large requests and the heuristic would allow that.  We
used to have an early break in the vmalloc allocator for killed tasks
but this has been reverted by commit b8c8a338f7 ("Revert "vmalloc:
back off when the current task is killed"").  There are likely other
similar code paths which do not check for fatal signals in an
allocation&charge loop.  Also there are some kernel objects charged to a
memcg which are not bound to a process life time.

It has been observed that it is not really hard to trigger these
bypasses and cause global OOM situation.

One potential way to address these runaways would be to limit the amount
of excess (similar to the global OOM with limited oom reserves).  This
is certainly possible but it is not really clear how much of an excess
is desirable and still protects from global OOMs as that would have to
consider the overall memcg configuration.

This patch is addressing the problem by removing the heuristic
altogether.  Bypass is only allowed for requests which either cannot
fail or where the failure is not desirable while excess should be still
limited (e.g.  atomic requests).  Implementation wise a killed or dying
task fails to charge if it has passed the OOM killer stage.  That should
give all forms of reclaim chance to restore the limit before the failure
(ENOMEM) and tell the caller to back off.

In addition, this patch renames should_force_charge() helper to
task_is_dying() because now its use is not associated witch forced
charging.

This patch depends on pagefault_out_of_memory() to not trigger
out_of_memory(), because then a memcg failure can unwind to VM_FAULT_OOM
and cause a global OOM killer.

Miaohe Lin 64bde0c2db mm/zsmalloc.c: close race window between zs_pool_dec_isolated() and zs_unregister_migration()
[ Upstream commit afe8605ca45424629fdddfd85984b442c763dc47 ]

There is one possible race window between zs_pool_dec_isolated() and
zs_unregister_migration() because wait_for_isolated_drain() checks the
isolated count without holding class->lock and there is no order inside
zs_pool_dec_isolated().  Thus the below race window could be possible:

  zs_pool_dec_isolated		zs_unregister_migration
    check pool->destroying != 0
				  pool->destroying = true;
				  smp_mb();
				  wait_for_isolated_drain()
				    wait for pool->isolated_pages == 0
    atomic_long_dec(&pool->isolated_pages);
    atomic_long_read(&pool->isolated_pages) == 0

Since we observe the pool->destroying (false) before atomic_long_dec()
for pool->isolated_pages, waking pool->migration_wait up is missed.

Fix this by ensure checking pool->destroying happens after the
atomic_long_dec(&pool->isolated_pages).

Vijayanand Jitta f72f41f50c UPSTREAM: mm: vmalloc: prevent use after free in _vm_unmap_aliases
A potential use after free can occur in _vm_unmap_aliases where an already
freed vmap_area could be accessed, Consider the following scenario:

Process 1						Process 2

__vm_unmap_aliases					__vm_unmap_aliases
	purge_fragmented_blocks_allcpus				rcu_read_lock()
		rcu_read_lock()
			list_del_rcu(&vb->free_list)
									list_for_each_entry_rcu(vb .. )
	__purge_vmap_area_lazy
		kmem_cache_free(va)
										va_start = vb->va->va_start

Here Process 1 is in purge path and it does list_del_rcu on vmap_block and
later frees the vmap_area, since Process 2 was holding the rcu lock at
this time vmap_block will still be present in and Process 2 accesse it and
thereby it tries to access vmap_area of that vmap_block which was already
freed by Process 1 and this results in use after free.

Fix this by adding a check for vb->dirty before accessing vmap_area
structure since vb->dirty will be set to VMAP_BBMAP_BITS in purge path
checking for this will prevent the use after free.

Yang Shi 6d67b2a73b mm: khugepaged: skip huge page collapse for special files
commit a4aeaa06d45e90f9b279f0b09de84bd00006e733 upstream.

The read-only THP for filesystems will collapse THP for files opened
readonly and mapped with VM_EXEC.  The intended usecase is to avoid TLB
misses for large text segments.  But it doesn't restrict the file types
so a THP could be collapsed for a non-regular file, for example, block
device, if it is opened readonly and mapped with EXEC permission.  This
may cause bugs, like [1] and [2].

This is definitely not the intended usecase, so just collapse THP for
regular files in order to close the attack surface.

Rongwei Wang 69a7fa5cb0 mm, thp: bail out early in collapse_file for writeback page
commit 74c42e1baacf206338b1dd6b6199ac964512b5bb upstream.

Currently collapse_file does not explicitly check PG_writeback, instead,
page_has_private and try_to_release_page are used to filter writeback
pages.  This does not work for xfs with blocksize equal to or larger
than pagesize, because in such case xfs has no page->private.

This makes collapse_file bail out early for writeback page.  Otherwise,
xfs end_page_writeback will panic as follows.

SPF patchset introduced an mmu_notifier imbalance by adding a new exit
path that skips mmu_notifier_invalidate_range_only_end after calling
mmu_notifier_invalidate_range_start. This triggers a BUG in KVM driver
checking for mmu_notifier_count to remain balanced

Miaohe Lin b41fd8f5d2 mm, slub: fix incorrect memcg slab count for bulk free
commit 3ddd60268c24bcac9d744404cc277e9dc52fe6b6 upstream.

kmem_cache_free_bulk() will call memcg_slab_free_hook() for all objects
when doing bulk free.  So we shouldn't call memcg_slab_free_hook() again
for bulk free to avoid incorrect memcg slab count.

In error path, the random_seq of slub cache might be leaked.  Fix this

Miaohe Lin 48843dd23c mm, slub: fix mismatch between reconstructed freelist depth and cnt
commit 899447f669da76cc3605665e1a95ee877bc464cc upstream.

If object's reuse is delayed, it will be excluded from the reconstructed
freelist.  But we forgot to adjust the cnt accordingly.  So there will
be a mismatch between reconstructed freelist depth and cnt.  This will
lead to free_debug_processing() complaining about freelist count or a
incorrect slub inuse count.
