mm/list_lru: drain before clearing xarray entry on reparent
memcg_reparent_list_lrus() clears the dying memcg's xarray entry with
xas_store(&xas, NULL) before reparenting its per-node lists into the
parent. This opens a window where a concurrent list_lru_del() arriving
for the dying memcg sees xa_load() == NULL, walks to the parent in
lock_list_lru_of_memcg(), takes the parent's per-node lock, and calls
list_del_init() on an item still physically linked on the dying memcg's
list.
If another in-flight thread holds the dying memcg's per-node lock at the
same moment (another list_lru_del, or a list_lru_walk_one running an
isolate callback), both threads modify ->next/->prev pointers on the same
physical list under different locks. Adjacent items can corrupt each
other's links.
Fix it by reversing the order: reparent each per-node list and mark the
child's list lru dead and then clear the xarray entry. Any concurrent
list_lru op that finds the still-set xarray entry either takes the dying
memcg's per-node lock (synchronizing with the drain) or sees LONG_MIN and
walks to the parent, where the items now live.

mm/damon/lru_sort: handle ctx allocation failure
DAMON_LRU_SORT allocates the damon_ctx object for its kdamond in its init
function. damon_lru_sort_enabled_store() wrongly assumes the allocation
will always succeed once tried. If the damon_ctx allocation was failed,
therefore, code execution reaches to damon_commit_ctx() while 'ctx' is
NULL. As a result, it dereferences the NULL 'ctx' pointer. Avoid the
NULL dereference by returning -ENOMEM if 'ctx' is NULL.

mm/damon/reclaim: handle ctx allocation failure
Patch series "mm/damon/{reclaim,lru_sort}: handle ctx allocation failures".
DAMON_RECLAIM and DAMON_LRU_SORT could dereference NULL pointers if their
damon_ctx object allocations fail. The bugs are expected to happen
infrequently because the allocations are arguably too small to fail on
common setups. But theoretically they are possible and the consequences
are bad. Fix those.
The issues were discovered [1] by Sashiko.
This patch (of 2):
DAMON_RECLAIM allocates the damon_ctx object for its kdamond in its init

zram: fix use-after-free in zram_bvec_write_partial()
zram_read_page() picks the sync or async backing device read path based on whether the parent bio is NULL. zram_bvec_write_partial() passes its parent bio down, so for ZRAM_WB slots the read is dispatched asynchronously and zram_read_page() returns 0 while the bio is still in flight. The caller then runs memcpy_from_bvec(), zram_write_page() and __free_page() on the buffer, leaving the async read to write into a freed page. zram_bvec_read_partial() was switched to NULL in commit |

mm/cma_sysfs: skip inactive CMA areas in sysfs
cma_activate_area() can fail after a CMA area has already been added to
cma_areas[]. In that case the area is left in the global array, but it
does not reach the point where CMA_ACTIVATED is set.
cma_sysfs_init() currently walks all cma_area_count entries and creates
sysfs files for every area, including ones that failed activation. These
areas are not usable CMA areas and should not be exposed to userspace as
valid CMA regions.
If such an inactive area is exposed, userspace sees a CMA directory whose
read-only accounting files report zeros. total_pages and available_pages
report zero because the failed activation path clears cma->count and
cma->available_count, while the allocation and release counters also stay
at zero because the area cannot service CMA allocations. This makes the
failed area look like a valid but empty CMA region and can mislead tests,
monitoring, and diagnostics.
Skip CMA areas that did not reach CMA_ACTIVATED when creating the sysfs
objects. Since inactive entries can now be skipped, make the error unwind
tolerate entries that never had cma_kobj initialized.

ipc/shm: serialize orphan cleanup with shm_nattch updates
shm_destroy_orphaned() walks the shm idr under shm_ids(ns).rwsem, but that
does not serialize all fields tested by shm_may_destroy(). In particular,
shm_nattch is updated while holding shm_perm.lock, and attach paths can do
that without holding the rwsem.
Do not decide that an orphaned segment is unused before taking the object
lock. Move the shm_may_destroy() check under shm_perm.lock, matching the
other destroy paths, and unlock the segment when it no longer qualifies
for removal.

userfaultfd: remove redundant check in vm_uffd_ops()
Lorenzo says:
static const struct vm_uffd_ops *vma_uffd_ops(struct vm_area_struct *vma)
{
if (vma_is_anonymous(vma))
return &anon_uffd_ops;
return vma->vm_ops ? vma->vm_ops->uffd_ops : NULL;
}
This is doing a redundant check _and_ making life confusing, as if
!vma->vm_ops is a condition that can be reached there, it can't, as
vma_is_anonymous() is literally a !vma->vm_ops check :)
Remove the redundant check.

userfaultfd: verify VMA state across UFFDIO_COPY retry
Patch series "userfaultfd: verify VMA state across UFFDIO_COPY retry", v2. ... and two more small fixes. This patch (of 3): mfill_copy_folio_retry() drops the VMA lock for copy_from_user() and reacquires it afterwards. The destination VMA can be replaced during that window. The existing check compares vma_uffd_ops() before and after the retry, but if a shmem VMA with MAP_SHARED is replaced with a shmem VMA with MAP_PRIVATE (or vice versa) the replacement goes undetected. The change from MAP_PRIVATE to MAP_SHARED will treat the folio allocated with shmem_alloc_folio() as anonymous and this will cause BUG() when mfill_atomic_install_pte() will try to folio_add_new_anon_rmap(). The change from MAP_SHARED to MAP_PRIVATE allows injection of folios into the page cache of the original VMA. There is no need to change for hugetlb because it never uses mfill_copy_folio_retry(). Introduce helpers for more comprehensive comparison of VMA state: - mfill_retry_state_save() to save the relevant VMA state into a struct mfill_retry_state (original uffd_ops, relevant VMA flags, vm_file and pgoff) before dropping the lock - mfill_retry_state_changed() to compare the saved state with the state of the VMA acquired after retaking the locks - mfill_retry_state_put() to release vm_file pinning. Use DEFINE_FREE() cleanup to wrap mfill_retry_state_put() to avoid complicating error handling paths in mfill_copy_folio_retry().

mm/hugetlb_vmemmap: fix incorrect vmemmap restore in rollback
vmemmap_restore_pte() rebuilds restored vmemmap pages from a tail-page
template derived from compound_head(). This is wrong when the current PTE
already maps a page whose contents are not tail-page metadata.
In the rollback path of vmemmap_remap_free(), the first restored PTE is
backed by vmemmap_head and contains head-page metadata. Reconstructing
that page from a tail-page template overwrites the head-page state and
corrupts the restored vmemmap page.
Fix this by copying the full page from the page currently mapped by the
PTE. Also pass vmemmap_tail to the rollback walk so only PTEs backed by
the shared tail page are restored, while the head PTE remains mapped to
vmemmap_head. Add VM_WARN_ON_ONCE() checks for unexpected cases.

mm/damon/ops-common: call folio_test_lru() after folio_get()
damon_get_folio() speculatively calls folio_test_lru() before folio_try_get(). The folio can get freed and reallocated to a tail page. In the case, VM_BUG_ON_PGFLAGS() in const_folio_flags() can be triggered. Remove the speculative call. Also mark folio_test_lru() check right after folio_try_get() success as no more unlikely. The race should be rare. Also the problem can happen only if the kernel has enabled CONFIG_DEBUG_VM_PGFLAGS. No real world report of this issue has been made so far. This fix is based on only theoretical analysis. That said, a bug is a bug. A similar issue was also fixed via commit |

mm/cma: fix reserved page leak on activation failure
If cma_activate_area() fails after allocating only part of the range
bitmaps, the cleanup path still has to release the reserved pages when
CMA_RESERVE_PAGES_ON_ERROR is clear.
That is still worth doing even in this __init path. A bitmap_zalloc()
failure does not necessarily mean the system cannot make further progress:
freeing the reserved CMA pages can return a substantial amount of memory
to the buddy allocator and may relieve the temporary memory shortage that
caused the allocation failure in the first place.
However, the cleanup path currently uses the bitmap-freeing bound for page
release as well. That is only correct for ranges whose bitmap allocation
already succeeded. The failed range and all later ranges still keep their
reserved pages, so a partial bitmap allocation failure can permanently
leak them.
Fix this by releasing reserved pages for all ranges. Use the saved
early_pfn[] value for ranges whose bitmap allocation already succeeded and
for the failed range, and use cmr->early_pfn for later ranges whose bitmap
allocation was never attempted.

mm/memory-failure: fix hugetlb_lock AA deadlock in get_huge_page_for_hwpoison
Two concurrent madvise(MADV_HWPOISON) calls on the same hugetlb page can
trigger a recursive spinlock self-deadlock (AA deadlock) on hugetlb_lock
when racing with a concurrent unmap:
thread#0 thread#1
-------- --------
madvise(folio, MADV_HWPOISON)
-> poisons the folio successfully
madvise(folio, MADV_HWPOISON) unmap(folio)
try_memory_failure_hugetlb
get_huge_page_for_hwpoison
spin_lock_irq(&hugetlb_lock) <- held
__get_huge_page_for_hwpoison
hugetlb_update_hwpoison()
-> MF_HUGETLB_FOLIO_PRE_POISONED
goto out:
folio_put()
refcount: 1 -> 0
free_huge_folio()
spin_lock_irqsave(&hugetlb_lock)
-> AA DEADLOCK!
The out: path in __get_huge_page_for_hwpoison() calls folio_put() to drop
the GUP reference while the hugetlb_lock is still held by the hugetlb.c
wrapper get_huge_page_for_hwpoison(). If concurrent unmap has released
the page table mapping reference, folio_put() drops the folio refcount to
zero, triggering free_huge_folio() which attempts to re-acquire the
non-recursive hugetlb_lock.
Fix this by moving hugetlb_lock acquisition from the hugetlb.c wrapper
into get_huge_page_for_hwpoison(). Place spin_unlock_irq() before the
folio_put() at the out: label so the folio is always released outside the
lock.

mm/cma_debug: fix invalid accesses for inactive CMA areas
cma_activate_area() can fail after allocating range bitmaps. Its cleanup path frees those bitmaps, but only clears cma->count and cma->available_count. It leaves cma->nranges and each range's count in place, so cma_debugfs_init() can still register debugfs files for an area that never activated successfully. That exposes two problems. Reading the bitmap file can make debugfs walk a freed range bitmap and trigger an invalid memory access. Reading maxchunk can also take cma->lock even though that lock is initialized only on the successful activation path. Fix this by creating debugfs entries only for CMA areas that reached CMA_ACTIVATED. |

memcg: use round-robin victim selection in refill_stock
Harry Yoo reported that get_random_u32_below() is not safe to call in the
nmi context and memcg charge draining can happen in nmi context.
More specifically get_random_u32_below() is neither reentrant- nor
NMI-safe: it acquires a per-cpu local_lock via local_lock_irqsave() on the
batched_entropy_u32 state. An NMI that lands on a CPU mid-update of the
ChaCha batch state and recurses into the random subsystem would corrupt
that state. The memcg_stock local_trylock prevents re-entry on the percpu
stock itself, but cannot protect an unrelated subsystem's per-cpu lock.
Replace the random pick with a per-cpu round-robin counter stored in
memcg_stock_pcp and serialized by the same local_trylock that already
guards cached[] and nr_pages[]. No atomics, no random calls, no extra
locks needed.

libbpf: fix off-by-one in emit_signature_match jump offset
The offset for the cleanup-label jump is computed before the MOV R7
instruction is emitted, but the JMP lands after it. Account for the
extra insn in the offset calculation (-2 instead of -1). Drop the
redundant self-loop in the else branch; gen->error = -ERANGE already
marks the generation as failed.

KVM: SVM: Disable AVIC IPI virtualization on Hygon Family 18h (erratum #1235)
Hygon Family 18h CPUs are derived from AMD Family 17h (Zen1) silicon and
share the same erratum #1235: hardware may read a stale IsRunning=1 bit
during ICR write emulation and silently fail to generate an
AVIC_IPI_FAILURE_TARGET_NOT_RUNNING VM-Exit on the sending vCPU.
The absence of the VM-Exit causes KVM to miss the required wakeup of
blocking target vCPUs, leading to hung vCPUs and unbounded delays in
guest execution.
Extend the existing AMD Family 17h erratum #1235 workaround to also cover
Hygon Family 18h. With IPI virtualization disabled, KVM never sets
IsRunning=1 in the Physical ID table, so every non-self IPI generates a
VM-Exit and is correctly emulated.

KVM: selftests: Verify that KVM returns the configured APIC cycle length
Add checks in the APIC bus clock test to verify that querying KVM_CAP_X86_APIC_BUS_CYCLES_NS on the VM after changing the frequency returns the VM's actual APIC cycle length, not KVM's default. For giggles, verify that KVM still returns its default frequency for the system-scoped check.

KVM: x86: Return the VM's configured APIC bus frequency when queried
When KVM_CAP_X86_APIC_BUS_CYCLES_NS is queried on a specific VM, return the
VM's configured APIC bus frequency, not KVM's default. Aside from the fact
that returning the default frequency is blatantly wrong if userspace has
changed the frequency, returning the configured frequency means userspace
can blindly trust the result, e.g. when filling PV CPUID information that
communicates the APIC bus frequency to the guest.
