SCSI misc on 20260821

Summary of patch series in this merge:
- The 2 patch series "mm: drop "sub" prefix from various places" from
Dev Jain implements some page->folio conversion and a naming cleanup.
- The 2 patch series "mm/kasan: remove redundant initialization for
kasan_flag_write_only" from Igor Putko provides some KASAN cleanup work.
- The 2 patch series "mm/filemap: reduce unnecessary xarray lookups"
from Chi Zhiling provides a small speedup in the pagecaache read code.
- The 4 patch series "mm/percpu: Fix possible NOFS/NOIO reclaim
recursion" from Kaitao Cheng improves a few things in the vmalloc code -
mainly the avoidance of GFP_KERNEL allocations when the caller asked for
GFP_NOFS or GFP_NOIO.
- The 3 patch series "mm/kmemleak: avoid soft lockup when scanning task
stacks" from Breno Leitao avoids a soft lockup watchdog trigger from the
kmemleak scanning code in extreme situations.
- The 6 patch series "mm/page_owner: misc cleanups" from Ye Liu is a
collection of unrelated cleanups to the page_owner code. For some
reason lots of people have been working on the page_owner code this
cycle.
- The 4 patch series "mm: convert to walk_page_range_vma() to eliminate
find_vma()" from Kefeng Wang simplifies and accelerates the page walking
library function.
- The 3 patch series "mm/migrate: preparatory cleanups for batch copy
and offload" from Shivank Garg implements cleanups in the migration
code.
- The 4 patch series "mm/page_owner: add per-fd filter infrastructure
for print_mode and NUMA filtering" from Zhen Ni provides per-fd
filtering to page_owner in order to reduce the sometimes vast amount of
output it can produce.
- The 19 patch series "mm: Refactor bootmem gigantic hugepage
allocation" from Muchun Song is a "set of fixes and preparatory cleanups
around bootmem HugeTLB handling, sparse initialization ordering, and
related vmemmap setup".
- The 4 patch series "mm/zsmalloc: reduce lock contention in zs_free()"
from Wenchao Hao reduces lock contention in zs_free(), which dominates
the unmap path under memory pressure on Android (LMK kills) and on x86
servers running zswap-heavy workloads. Up to 1.83x improvement in
microbenchmarking.
- The 2 patch series "move alloc_tag.c file under mm/" from Suren
Baghdasaryan does that.
- The 6 patch series "samples/damon: handle damon_{start,stop}()
failures" from SJ Park fixes improper handling of damon_start(),
damon_stop(), and damon_call() failures across DAMON sample modules to
prevent potential memory leaks, operation disruptions and use-after-free
bugs.
- The 11 patch series "mm/damon/sysfs: kobject_del() directories that
users can create/remove" from SJ Park resolves an issue where delayed
sysfs directory removal under CONFIG_DEBUG_KOBJECT_RELEASE causes
creation failures due to duplicate directory names by adding missing
kobject_del() calls before creating new directories.
- The 3 patch series "mm: cleanup clear_not_present_full_ptes()" from
David Hildenbrand cleans up the core pte handling code.
- The 3 patch series "selftests/damon: misc fixes for test bugs" from
Kunwu Chan fixes several bugs in the DAMON selftests.
- The 2 patch series "selftests/damon: fix memcg_path staging handling"
from Cheng Nie fixes a bug in _damon_sysfs.py for damos_filter
memcg_path setup, and adds a test case for it in sysfs.py.
- The 2 patch series "selftests/damon: test kdamond refresh_ms" from
Ruslan Valiyev introduces selftest coverage for DAMON's refresh_ms sysfs
feature by updating the test control module and verifying that scheme
stats update automatically without manual intervention.
- The 5 patch series "mm/damon: five misc fixups" from Akinobu Mita
contains miscellaneous DAMON fixups.
- The 2 patch series "mm/damon/core: detect internal variation above
max_nr_regions/2" from Jiayuan Chen fixes DAMON's region splitting
behavior when region counts exceed half the maximum budget by
dynamically scaling down the split fraction as the limit approaches,
preventing large regions from staying un-split, and adds corresponding
KUnit test coverage.
- The 6 patch series "mm: preparatory patches for PMD level swap
entries" from Usama Arif refactors and cleans up PMD softleaf helpers,
call sites, and architecture flags to lay the groundwork for a follow-up
series that introduces PMD page table swap entries.
- The 11 patch series "mm/damon: update, optimize, and clean up doc,
tests, and code" from SJ Park updates DAMON design and ABI
documentation, expands unit and selftest coverage, optimizes
damon_commit_target_regions(), and cleans up recently added sysfs
interface code for better readability.
- The 2 patch series "mm/vmpressure: reduce CPU, memory and code
overhead on cgroup v2" from Usama Arif optimizes vmpressure() by
skipping unnecessary work on cgroup v2 for userspace event notifications
and refactors v1-only eventfd handling into mm/memcontrol-v1.c to reduce
memory overhead and code complexity.
- The 10 patch series "selftests/mm: refactor pkey helpers and fix mmap
error handling" from Hongfu Li refactors pkeys shared tracing and
assertion helpers into a common file, unifies protection key selftests
to use consistent diagnostic logging and assertions, and enforces
standardized MAP_FAILED return checks for mmap() calls across the tests.
- The 18 patch series "mm/damon: optimize out nr_accesses_bp" from SJ
Park replaces the error-prone, continuously updated nr_accesses_bp field
in damon_region with an on-demand moving sum function
(damon_nr_accesses_mvsum()), reducing structure memory overhead and
avoiding state corruption bugs.
- The 6 patch series "Open HugeTLB allocation routine for more generic
use" from Ackerley Tng decouples HugeTLB folio allocation from VMA
dependencies by introducing hugetlb_alloc_folio(), enabling subsystems
like guest_memfd to allocate HugeTLB folios without standard VMA
reservations or pseudo-VMAs.
- The 3 patch series "mm/damon: provide pseudo moving sum probe_hits"
from SJ Park integrates DAMON's probe_hits attribute counter into the
pseudo moving sum infrastructure, enabling real-time, online monitoring
without waiting for full aggregation intervals.
- The 18 patch series "mm: Some cleanups for page allocator APIs" from
Brendan Jackman simplifies and refactors the page allocator entry points
and flags by unifying allocation paths, adding internal alloc_flags
arguments, and eliminating redundant __ prefixed alloc_pages variants.
- The 5 patch series "Fix incorrect access of hugetlb pte entries" from
Dev Jain enforces the consistent use of huge_ptep_get() instead of
ptep_get() for HugeTLB entries and fixes an unaligned address issue in
arm64's huge_ptep_get() implementation.
- The 8 patch series "mm/damon: validate all parameters in the core"
from SJ Park consolidates parameter validation into the DAMON core
specifically within damon_start() and damon_commit_ctx() to centralize
error checking, eliminate caller-side redundant checks and to improve
maintenance efficiency.
- The 3 patch series "tools/mm/page_owner_sort: fix filtering and
cleanup issues" from Yichong Chen renames is_need() to filter_record()
for clearer return semantics, fixes per-record allocation memory leaks
and bounds output copies in search_pattern() to address an existing
buffer issue.
- The 4 patch series "memcg: bail out reclaim when memcg is dying" from
Jiayuan Chen mitigates a system-wide stall which occurs when a cgroup is
removed while one of its memory control files is doing synchronous
reclaim.
- The 5 patch series "mm/memory-failure: add panic option for
unrecoverable pages" from Breno Leitao introduces an opt-in
vm.panic_on_unrecoverable_memory_failure sysctl that immediately panics
the kernel on unrecoverable memory errors in kernel-owned pages to
preserve error context and prevent delayed, silent data corruption.
- The 11 patch series "mm/damon: refactor damon_{start,stop,commit}()
for simple error handling" from SJ Park refactors the DAMON core API
functions to guarantee that all contexts are fully stopped when
damon_start(), damon_stop(), or damon_commit() fail, eliminating the
need for complex and error-prone caller-side cleanup code.
- The 5 patch series "Keep tail page private zero at free and folio
split" from Zi Yan adds checks to ensure tail_page->private is zero when
freeing compound or high-order pages and when promoting tail pages
during large folio splits. By validating these fields at free and split
time, it allows the removal of redundant private field clearing inside
prep_compound_tail().
- The 4 patch series "mm: drop redundant lru_add_drain in anon folio
reuse paths" from Barry Song eliminates redundant lru_add_drain() calls
in wp_can_reuse_anon_folio() and do_swap_page() to reduce LRU lock
contention and system overhead.
By validating folio refcounts against the LRU cache before draining
and removing unnecessary drains in the swap path, it achieves up to a
30.5% reduction in drain calls during heavy swap workloads.
- The 3 patch series "mm: clean up folio LRU and swap declarations" from
Jianyue Wu reorganizes folio LRU and swap code by relocating
page-cluster state to mm/swap_state.c, renaming mm/swap.c to mm/folio.c,
and moving MM-internal reclaim declarations into mm/internal.h.
- The 15 patch series "userfaultfd: working set tracking for VM guest
memory" from Kiryl Shutsemau adds userfaultfd support for tracking the
working set of VM guest memory, so a VMM can identify hot pages and
reclaim cold ones to tiered or remote storage.
- The 10 patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part
2)" from David Hildenbrand removes the remaining pieces of
CONFIG_HAVE_BOOTMEM_INFO_NODE, performing some smaller cleanups around
freeing of reserved vmemmap pages on the way.
- The 7 patch series "mm/damon: update probe hits for runtime parameter
commits" from SJ Park ensures that DAMON's probe_hits attribute counter
is properly updated when monitoring intervals are changed at runtime,
matching the behavior of nr_accesses. To achieve this, it refactors and
renames existing helper functions for shared use, applies the updates to
probe_hits, and handles edge cases in damon_probe_hits_mvsum() to
maintain measurement accuracy.
- The 3 patch series "KSM: performance optimizations for rmap_walk_ksm"
from xu xin resolves a severe KSM reverse-mapping performance bottleneck
where thousands of split VMAs sharing a single anon_vma cause extended
lock contention. By adding an interval-filtering check during the rmap
walk, it reduces worst-case anon_vma lock hold times from over 500ms
down to under 2ms, preventing application freezes and latency spikes
under memory pressure.
- The 3 patch series "mm: split a couple of headers from internal.h"
from Mike Rapoport splits declarations related to mm_init, memblock,
vmalloc and sparse into new headers.
- The 2 patch series "KSM: use linear_page_index in collect_procs_ksm()"
from xu xin applies the interval tree optimization from rmap_walk_ksm()
to collect_procs_ksm() to avoid iterating over non-matching VMAs during
KSM memory error handling. It hoists loop-invariant address
initialization and restricts the anon_vma_interval_tree_foreach walk to
a targeted page offset range, reducing redundant checks and improving
lookup efficiency.
- The 3 patch series "selftests/mm: avoid false failures in hugetlb and
KSM tests" from Sayali Patil fixes issues in the hugetlb and KSM MM
selftest categories that can report failures when the prerequisites for
the tests are not satisfied.
- The 19 patch series "mm/damon: introduce data attributes only
monitoring" from SJ Park introduces attribute-weighted region management
in DAMON, allowing users to prioritize specific data attributes (such as
page sizes or cgroups) over or instead of access monitoring.
By assigning weights to attribute probes, DAMON can completely disable
access tracking and adjust monitoring regions based on weighted
probe-hit counters to optimize monitoring quality for attribute-focused
workloads.
- The 8 patch series "mm/hmm: Add mmap lock-drop support for
userfaultfd-backed mappings" from Stanislav Kinsburskii extends
hmm_range_fault() to support userfaultfd-backed regions by allowing the
mmap lock to be dropped during fault handling via a new
hmm_range_fault_locked() helper.
By accepting a locked pointer and signaling retry status when lock
release occurs, it enables page fault resolution in userfaultfd regions
while preserving backward compatibility for existing callers.
- The 33 patch series "mm: make VMA page offset handling more
consistent" from Lorenzo Stoakes cleans up and standardizes how
vma->vm_pgoff is accessed and manipulated across file-backed and
anonymous mappings in the kernel.
It introduces dedicated helper functions such as vma_start_pgoff(),
vma_end_pgoff(), vma_set_pgoff() and linear_page_delta() while renaming
rmap interval tree helpers to better reflect their functionality.
These changes establish a cleaner foundation for future work that will
unify virtual page offset indexing for all anonymous and CoW'd folios.
- The 3 patch series "mm: handle device-private PMDs in walk callbacks"
from Usama Arif addresses kernel panics and state corruption caused by
MM walk callbacks reaching non-present device-private PMD swap entries
created during HMM migrations.
It ensures that functions which acquire pmd_trans_huge_lock() properly
recognize device-private PMDs instead of assuming a present THP or a
standard migration entry.
- The 5 patch series "mm/rmap: Refactor try_to_unmap_one" from Dev Jain
refactors try_to_unmap_one by modularizing Hugetlb, anonymous-lazyfree,
and anonymous-swapbacked logic into dedicated functions, laying the
structural groundwork for batched anonymous large folio unmapping.
- The 4 patch series "Docs/ABI/damon: sysfs ABI document fixes and
additions" from Song Hu fixes typos and fills in missing entries in the
DAMON sysfs ABI document.
- The 10 patch series "dax/kmem: atomic whole-device hotplug via sysfs"
from Gregory Price introduces an atomic sysfs state attribute and
supporting DAX/MM infrastructure to prevent userland races when
offlining and removing entire memory regions.
By adding an unplugged state alongside standard online modes, it
enables whole-device atomic hotplug control while preserving backward
compatibility.
- The 13 patch series "mm: convert more vm_flags_t users to vma_flags_t"
from Lorenzo Stoakes continues transitioning the kernel from the
deprecated vm_flags_t type to vma_flags_t across core memory management
infrastructure.
It replaces legacy type usage in core functions such as do_mmap(),
unmapped area allocation, mm->def_vma_flags, and VMA operations like
mlock, mprotect, and mremap.
- The 2 patch series "Two small patches to clean up mm/mm_slot.h" from
xu xin refactors mm_slot.h by introducing mm_slot_remove() to unify
duplicate slot deletion sequences in khugepaged and KSM. It also adds
code documentation explaining why mm_slot_lookup and mm_slot_insert must
remain as preprocessor macros rather than static inline functions.
- The 10 patch series "mm/damon/core: hide core-private struct fields"
from SJ Park cleans up DAMON core structures by consistently marking
internal-only fields with private: comment tags to prevent improper
direct access from outer layers.
It enforces encapsulation across core structures including
damon_region, damon_target, and damon_ctx and updates DAMON_SYSFS to
interact through approved access APIs instead of exposing raw struct
members.
- The 6 patch series "mm/damon: unurgent fixes for infinite loop, NULL
de-ref and races" from SJ Park addresses potential infinite loops, NULL
dereferences, and race conditions identified in DAMON.
It fixes an infinite loop triggered by extreme user configurations, a
NULL pointer dereference within unit tests and minor monitoring
accuracy degradation caused by subtle runtime races.
- The 2 patch series "mm/page_alloc: fixes for free_pages_nolock() on
RT/UP" from Brendan Jackman fixes an NMI safety flaw in
__free_frozen_pages() where freeing pages on non-SMP or PREEMPT_RT
kernels can bypass can_spin_trylock() checks via non-PCP or isolated
migration paths.
It also resolves potential kernel crashes and privilege escalation
risks triggered when BPF tracing runs in NMI context alongside memory
hotplug or large allocation frees.
- The 4 patch series "mm/page_alloc: couple of followups for recent
cleanups" from Brendan Jackman cleans up and updates page allocator
nomenclature, documentation, and debug assertions.
It aligns internal FPI_ flags with the public "nolock" naming
convention, removes outdated internal implementation details from
high-level page allocator comments, and eliminates obsolete VM_BUG_ON()
assertions in allocation paths.
- The 3 patch series "mm/mseal: further cleanups" from Lorenzo Stoakes
refactors and simplifies the mseal implementation by clarifying API
boundaries and removing unnecessary code complexity.
It replaces generic do_mseal() usage outside the syscall with a
dedicated mseal_mmap_page_zero() helper for MMAP_PAGE_ZERO, eliminates
mm_struct parameters to enforce that sealing applies only to
current->mm, and streamlines overall logic and comments with no
functional changes intended.
- The 4 patch series "mm/vmscan: fix swappiness=max and clean up
per-node proactive reclaim" from Ridong Chen resolves reclaim behavior
bugs and cleans up function parameters across memory reclaim paths.
It fixes swappiness=max in both standard reclaim and MGLRU so
unswappable anonymous memory no longer falls back to evicting page
cache, ensures reclaim_store() returns accurate error codes instead of
collapsing all failures into -EAGAIN, and removes the obsolete gfp_mask
parameter from __node_reclaim().
- The 6 patch series "mm: mincore: misc cleanups" from Kefeng Wang
cleans up and simplifies the mincore code. Most importantly, it removes
the historical special behavior that always reports VM_PFNMAP pages as
non-resident.
- The 2 patch series "mm/huge_memory: drop dead split helper variants"
from Kiryl Shutsemau implements two trivial cleanups in the folio split
API.
- The 7 patch series "mm/damon: fix uninitialized DAMOS field and kunit
exec expectation bugs" from SJ Park resolves minor operational and
testing bugs in DAMON identified by Sashiko. It initializes the
damos->last_applied field to prevent occasional efficiency degradation
and fixes invalid memory accesses in DAMON KUnit tests during test
failure handling.
- The 3 patch series "cleanup for stable_page_flags()" from Jinjiang Tu
cleans up and refactors stable_page_flags() used by /proc/kpageflags
without altering functionality.
It uses BIT_ULL() to prevent shift-overflow warnings on 64-bit flag
bits, converts folio-specific flag checks to standard folio_test_*()
helpers, and removes redundant CONFIG_PAGE_IDLE_FLAG handling.
- The 3 patch series "Batch unmap of uffd-wp file folios" from Dev Jain
extends batched folio unmapping support to file folios within
userfaultfd write-protect (uffd-wp) VMAs by adding batching capabilities
to pte_install_uffd_wp_if_needed().
This removes special-case restrictions on uffd-wp VMAs in
try_to_unmap_one(), significantly simplifying the function's control
flow and complexity.
- The 3 patch series "mm/early_ioremap: clarify and clean up
early_ioremap_reset()" from Sang-Heon Jeon clarifies and cleans up the
architecture-specific usage of __late_set_fixmap() and
__late_clear_fixmap() after early_ioremap_reset().
It adds explicit documentation regarding when early_ioremap_reset()
must be called and removes redundant macro definitions and reset calls
in the RISC-V and ARM64 architectures.
- The 4 patch series "mm: fix reclaim storms in defrag_mode" from
Johannes Weiner addresses severe performance regressions, swap storms,
and spurious OOMs caused by vm.defrag_mode=1 under high memory pressure
in Meta production.
It updates the page allocator slowpath so non-movable allocation
requests actively trigger direct reclaim and direct compaction at
pageblock_order scale, allowing them to claim whole pageblocks rather
than spinning unproductively.
- The 2 patch series "zram: lockmap tweaks" from Sebastian Siewior
optimizes and fixes lockdep tracking for zram devices by consolidating
per-entry lockmaps and isolating lock classes across multiple instances.
It reduces memory overhead by replacing per-entry lockdep_map instances
with a single map per struct zram, and assigns a dynamic lock_class_key
to each instance to prevent false deadlock reports when different zram
devices are backed by distinct filesystems.

maintain measurement accuracy.
- "KSM: performance optimizations for rmap_walk_ksm" (xu xin)
Resolve a severe KSM reverse-mapping performance bottleneck where
thousands of split VMAs sharing a single anon_vma cause extended lock
contention.
By adding an interval-filtering check during the rmap walk, it

Clean up and standardize how vma->vm_pgoff is accessed and
manipulated across file-backed and anonymous mappings in the kernel
It introduces dedicated helper functions such as vma_start_pgoff(),
vma_end_pgoff(), vma_set_pgoff() and linear_page_delta() while
renaming rmap interval tree helpers to better reflect their
functionality.
These changes establish a cleaner foundation for future work that
will unify virtual page offset indexing for all anonymous and CoW'd
folios.
- "mm: handle device-private PMDs in walk callbacks" (Usama Arif)
Address kernel panics and state corruption caused by MM walk
callbacks reaching non-present device-private PMD swap entries

VFIO updates for v7.3-rc1
- Add nv_falcon vfio selftest driver. The Falcon is a general-purpose
microcontroller embedded within NVIDIA GPUs, presenting a relatively
simple DMA programming interface. This adds another selftest target
for vfio-pci with real DMA transfers. (Rubin Du, Alex Williamson)
- Add allocation assertion helpers to vfio selftests and use them to
avoid variable length arrays and the compiler errors they generate.
(Alex Mastro)
- Fix use-after-free hazard where an init path error in MSI support
leaves a stray pointer that can later be reused or double-freed.
(Xiang Mei)
- Fix previous refactor of PCI BAR mappings to honor non_mappable_bars
flag, which otherwise generates a warning when trying to pci_iomap()
a 256TiB BAR on ISM devices on s390. (Farhan Ali)
- Add igb vfio selftest driver. Like nv_falcon, this provides another
target for DMA testing with vfio selftests, but importantly this
driver supports both physical 82576 NICs and the emulation model in
QEMU. This therefore enables a vfio selftest vector with no physical
hardware requirements. (Josh Hilke, Alex Williamson)
- Mark selftest fixture objects __maybe_unused to accommodate builds
with clang -Wunused-but-set-global. (David Matlack)
- Add error recovery for vfio-pci devices on s390x. This expands
devices which expose the existing error eventfd and introduces a
device feature for reporting firmware defined error state
information to the user, allowing recovery through hypervisor
channels. (Farhan Ali)

NFSD 7.3 Release Notes
Jeff Layton contributed CB_NOTIFY support to NFSD's NFSv4.1
directory delegations. The server used to recall a delegation as
soon as the directory changed. NFSD now watches delegated
directories through fsnotify and reports adds, removes, renames,
and directory attribute changes, carrying the filehandle and
attributes of the affected entry, so clients can keep their
caches. Some of the NOTIFY4 flags come from RFC 8881bis.
Jeff Layton also continued the netlink work that started in v7.2.
A new server-stats-get operation reports what /proc/net/rpc/nfsd
publishes, plus NFSv4 callback counts, and SUNRPC now keeps its
per-procedure call counts per network namespace, so a container
sees its own numbers. nfsstat reads all of this over netlink, with
a procfs fallback for older kernels.
SUNRPC's service thread pool mode selection is gone. Pernode is
the right choice on any host we run today, so the auto, global,
and percpu modes have been removed. A single-node host still gets
one pool. A multi-NUMA host now gets a pool per node.
sunrpc.pool_mode accepts the old names but no longer selects
anything.
The rest is bug fixes, clean-ups, and small optimizations: an
async COPY offload rework from Jeff Layton, more use-after-free
fixes in the NFSv4 state revocation paths, percpu counter
contention removed from the reply cache and IO accounting, and a
long list of hardening fixes from Chris Mason. Sincere thanks to
all contributors, reviewers, testers, and bug reporters who
participated in the v7.3 NFSD development cycle.

Networking changes for 7.3.
Core & protocols
----------------
- A few steps lowering rtnl_lock dependence:
- per-netns netdev unregistration for select SW drivers
(e.g. veth, ipvlan, tunnels)
- rtnl_lock-less FIB rule changes (RTM_NEWRULE and RTM_DELRULE)
- prepare software drivers and TC qdiscs for rtnl_lock-less GET
- Support BIG TCP (>64kB TSO) in UDP tunnels (vxlan, geneve).
- Support buffers larger than PAGE_SIZE in devmem zero-copy API.
- Improve MPTCP handling of extreme memory pressure handling,
when out-of-order queue had to be pruned.
- Report the per-group user count via RTM_GETMULTICAST.
- Expose the route deletion reason in RTM_DELROUTE.
- Add a SO_RIGHTS_NOTRUNC option to UNIX sockets to enable more useful
handling of LSM denials when receiving SCM_RIGHTS messages: instead
of truncating the message at the first blocked fd, keep every fd slot
and store the LSM errno in the blocked slot.
- IPv6 Segment Routing - support looking up the post-encap SID
(address) in a different/specified routing table.
- Support PRP RedBox (interlink) creation.
- Support per-nexthop UDP dst port in VXLAN.
- Continue converting getsockopt callbacks in a number of protocols
to iov_iter.

Merge tag 'net-next-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"One of the 'small improvements all over the place' releases for us.
It's hard to draw any direct comparisons because summer vacations
disrupted our patch processing (and presumably - generation) quite a
bit.
Quick and dirty count suggests we (Paolo and I) merged a very similar
number of net (632) and net-next (648) patches. This is not telling
the full story either because 1/3 to 1/2 of the net-next patches also
*seem* like AI-driven low priority fixes, cleanups and clarifications.
We are completely overwhelmed, of course. The glimmer of hope is that
we secured sufficient LLM budget and access (thank you Meta!) to run
reviews with multiple frontier models on each patch. This eliminates
some hallucinations. That said, in terms of review, the LLMs can only
do so much.
The sad truth is that our APIs (especially for rare events like PCIe
errors, timeouts etc) have always been racy, and now LLMs don't let us
ignore that. I expect our direction for the next release will be to
tweak the reviews a little bit more, but start shifting focus to
letting the LLMs take care of the busy work - managing patchwork,
automating common process complaints, editing commit messages, and
maybe applying patches which already got "reviewed-by" tags from
people we trust...
Core & protocols:
- A few steps lowering rtnl_lock dependence:
- per-netns netdev unregistration for select SW drivers (e.g.
veth, ipvlan, tunnels)
- rtnl_lock-less FIB rule changes (RTM_NEWRULE and RTM_DELRULE)
- prepare software drivers and TC qdiscs for rtnl_lock-less GET
- Support BIG TCP (>64kB TSO) in UDP tunnels (vxlan, geneve)
- Support buffers larger than PAGE_SIZE in devmem zero-copy API
- Improve MPTCP handling of extreme memory pressure handling, when
out-of-order queue had to be pruned
- Report the per-group user count via RTM_GETMULTICAST
- Expose the route deletion reason in RTM_DELROUTE
- Add a SO_RIGHTS_NOTRUNC option to UNIX sockets to enable more
useful handling of LSM denials when receiving SCM_RIGHTS messages:
instead of truncating the message at the first blocked fd, keep
every fd slot and store the LSM errno in the blocked slot
- IPv6 Segment Routing - support looking up the post-encap SID
(address) in a different/specified routing table
- Support PRP RedBox (interlink) creation
- Support per-nexthop UDP dst port in VXLAN

to iov_iter

Major changes:
- Redesign the verifier error reporting: failures now carry source and
instruction annotations along with the causal event history that led
to them, making program rejections far easier to debug and repair
(Kumar Kartikeya Dwivedi)
- Add arena argument support to kfuncs and struct_ops through the new
__arena and __arena__nullable suffixes (Tejun Heo, Puranjay Mohan,
Kumar Kartikeya Dwivedi, Ihor Solodrai)
- Signed BPF program loader rework to accommodate both BPF and security
community needs where the kernel runs the signature verification at
BPF_PROG_LOAD time before the LSM admission hook (Daniel Borkmann)
- Add a set of ksock kfuncs which let BPF LSM and syscall programs
create, connect and send on UDP sockets in order to emit telemetry
data (Mahe Tardy)
- Unify helper and kfunc call argument verification and classify kfunc
arguments purely from BTF into a generated bpf_func_proto which is
computed once at add-call time (Amery Hung)
Other features and fixes:
- Enable EXECMEM_ROX_CACHE for BPF allocations on x86 (Mike Rapoport)
- Add bidirectional VLAN support to bpf_fib_lookup() through the new
BPF_FIB_LOOKUP_VLAN and BPF_FIB_LOOKUP_VLAN_INPUT flags
(Avinash Duduskar)
- Infer zext_dst from static register liveness analysis to fix 32-bit
zero-extension semantics, and remove the artificial limitations on
pointer types eligible for spilling (Eduard Zingerman)
- Inline the numeric open-coded iterator kfuncs so that bpf_for() loops
no longer pay a kfunc call on every iteration (Puranjay Mohan)
- Add an arena-based bitmap data structure to libarena along with
serial and parallel selftests (Emil Tsalapatis)
- Teach resolve_btfids to discover kfuncs from the kernel's BTF ID sets
and to emit kfunc BTF decl tags, reducing the kernel build's
dependency on pahole features (Ihor Solodrai)
- Add BPF_F_ADJ_ROOM_DECAP_* flags to bpf_skb_adjust_room() so that
tunnel decapsulation can update the GSO and encapsulation state of
the skb (Nick Hudson)
- Fix the ring buffer pending_pos walk and the available-data
accounting on 32-bit position wrap (Israel Téllez García)
- Add memory usage accounting for arena maps and fix an mmap_lock
deadlock on arena lock failure (Jiayuan Chen)
- Add tracing_multi link info support to the kernel UAPI and bpftool,
and refactor the stack map code to run with preemption disabled
(Jiri Olsa)
- Support BPF_F_EGRESS in bpf_redirect_peer() to emit the skb in the
egress direction of the target's peer device (Jordan Rife)
- Add a KF_SPINLOCK_SAFE kfunc flag so that providers, in particular
modules, can declare kfuncs safe to call under bpf_spin_lock instead
of relying on the verifier's hard-coded allowlist (Kaitao Cheng)
- Introduce global percpu data for BPF programs with libbpf probing
and bpftool skeleton support, and stop exposing uninitialized kernel
heap memory when copying per-CPU map values (Leon Hwang)
- Add s390 JIT support for load-acquire and store-release instructions
(Maxim Khmelevskii)
- Fix a CFI mismatch in the task work callback and an arm64 KASAN
false positive after bpf_throw() (Mykyta Yatsenko)
- Reject writes through untrusted BTF pointers and bound the
rdonly/rdwr_buf_size kfunc arguments (Nicholas Dudar)
- Invalidate RCU pointers only after the final spin unlock and account
for preempt and IRQ disabled regions as overlapping RCU protection
(Ning Ding)
- Support mixing bpf2bpf calls and tail calls on RV64, add signed
operations and 32-bit atomics to the RV32 JIT, and add timed may_goto
support (Pu Lehui, Kuan-Wei Chiu, Feng Jiang)
- Fix a use-after-free on mm_struct in bpf_find_vma() for foreign tasks
and an mmap_lock leak in the irq_work path (Sanghyun Park)
- Populate mmap-able BPF array map memory lazily which makes mmap() O(1)
instead of proportional to the map size (Song Liu)
- Introduce a jit_required flag and reject programs with inlined
helpers when no JIT is available, where the interpreter would
otherwise jump into an invalid address (Tiezhu Yang)
- Fix the x86 JIT per-CPU address resolution into an extended register
where the REX prefix dropped the high destination register bit
(Vineet Gupta)
- Reject MEM_ALLOC BTF accesses past object bounds, arena frees below
the arena base, and mixed arena and ordinary atomic paths
(Yiyang Chen)
- Fix the trampoline handling of 128-bit arguments and of return values
larger than 8 bytes (Yonghong Song)
- Ensure that any fault prone load is rewritten with exception table
handling, and fix the arena load-acquire and atomic fetch handling
in the x86, arm64, riscv and s390 JITs (Daniel Borkmann)
- Many more fixes and cleanups across the verifier, arena, trampolines,
sockmap, cgroup, ring buffer, x86/arm64/riscv/s390 JITs, libbpf,
bpftool, resolve_btfids and selftests.

vduse: Add suspend
Implement suspend operation for vduse devices, so vhost-vdpa will offer that backend feature and userspace can effectively suspend the device. This is a must before get virtqueue indexes (base) for live migration, since the device could modify them after userland gets them.

vduse: add F_QUEUE_READY feature
Add the VDUSE_F_QUEUE_READY feature flag. This allows the kernel module to explicitly signal userspace when a specific virtqueue has been enabled. In scenarios like Live Migration of VirtIO net devices, the dataplane starts after the control virtqueue allowing QEMU to apply configuration in the destination device.

Timers and timekeeping core updates:
- Fix a subtly inconsistency in the timekeeping code, which fails to
account for the monotonicity adjustment in ntp_error. For small changes
of the clocksource multiplicator (+/-1) which are typically used by the
NTP PLL this is hardly to observe. But for larger adjustments,
e.g. caused by a direct frequency setting through adjtimex() the
one-time uncompensated offset is significant.
Cure this by adjusting ntp_error with the resulting offset so that the
discrepancy is smoothed away over time
- Make tick length calculations correct in NTP. The timekeeping core
takes the quantisation of the clocksource into account when calculating
the tick length to compensate for the deviation of the nominal
NTP_INTERVAL_LENGTH. While timekeeping gets this right, NTP is not
aware of that, which means it operates on the nominal value and not on
the actual value which is determined by the clock source frequency. The
rounding of a coarse clocksource like the ACPI PM timer results in a
+127 PPM deviation.
Cure this by exposing the deviation to the NTP code so that it can
operate on the same data as the timekeeping core. This is purely kernel
internal. User space still sees the nominal tick lenght via adjtimex().
- The accuracy of the NTP adjustments is fairly approximate as the code
assumes that the invocations are precisely in NTP interval frequency
ticks and the final adjustment can over and under-run.
Cure this by adjusting ntp_error by the intended skew on each tick to
achieve the desired rate.
- Handle the two competing skews of time offset and time adjustment
correctly by calculating the conflict portion between the skews and
adjusting both accordingly.
- A set of updates and improvements for the selftests
- The usual small fixes and improvements all over the place

- Many fixes and code improvements from bui duc phuc and Morimoto-san.
- Fixes for ordering problems in register default tables from Peter
Ujfalusi.
- Changes to use auto-cleanup for firmware to improve robustness from
Takashi Iwai.
- Support for firmware on more Awinc devices.
- Many changes in the Qualcomm driver stack, mostly around new platform
support.
- Support for AMD ACP7.B/F, Cirrus Logic CS35L62, Loongson 2K0300,
Meson GX formatter and interface, Qualcomm LPI MI2S, SM8475 and
WSA855 and Realtek RT1321 VA1/2 and RT766/7.

fscrypt updates for 7.3
The main change this cycle is a significant simplification that's been
overdue for a while now: standardizing on a single file contents
encryption implementation in ext4 and f2fs, instead of having two.
Specifically, the original filesystem-layer file contents encryption
implementation is removed, and the blk-crypto implementation is now
used unconditionally. blk-crypto delegates either to inline crypto
hardware or to the CPU via blk-crypto-fallback. The latter is
functionally equivalent to the original filesystem-layer code.
The blk-crypto implementation already existed, but previously it was
used only when the filesystem was mounted with "-o inlinecrypt". Now,
"-o inlinecrypt" just selects whether inline crypto hardware is used.
To allow maintaining that user control over hardware use, the
blk-crypto API is extended with a new flag BLK_CRYPTO_CFG_ALLOW_HW.
Overall, this removes quite a bit of redundant code from ext4, f2fs,
and fs/crypto/. It should make things easier for ongoing filesystem
efforts such as iomap support, large folios, and btrfs encryption.
(btrfs had already been planning to use blk-crypto exclusively.)
There are two small behavior changes of note:
- Direct I/O now works on encrypted files even without

Pull fscrypt updates from Eric Biggers:
"The main change this cycle is a significant simplification that's been
overdue for a while now: standardizing on a single file contents
encryption implementation in ext4 and f2fs, instead of having two.
Specifically, the original filesystem-layer file contents encryption
implementation is removed, and the blk-crypto implementation is now
used unconditionally. blk-crypto delegates either to inline crypto
hardware or to the CPU via blk-crypto-fallback. The latter is
functionally equivalent to the original filesystem-layer code.
The blk-crypto implementation already existed, but previously it was
used only when the filesystem was mounted with "-o inlinecrypt". Now,
"-o inlinecrypt" just selects whether inline crypto hardware is used.
To allow maintaining that user control over hardware use, the
blk-crypto API is extended with a new flag BLK_CRYPTO_CFG_ALLOW_HW.
Overall, this removes quite a bit of redundant code from ext4, f2fs,
and fs/crypto/. It should make things easier for ongoing filesystem
efforts such as iomap support, large folios, and btrfs encryption
(btrfs had already been planning to use blk-crypto exclusively.)
There are two small behavior changes of note:
- Direct I/O now works on encrypted files even without "-o inlinecrypt",
rather than falling back to buffered I/O. This is effectively a
bugfix, though I'll continue to keep an eye out for any user that
may have been depending on the buffered I/O fallback.
- IV_INO_LBLK_32 policies are no longer supported in certain cases

net: af_unix: useful handling of LSM denials on SCM_RIGHTS
Right now if some LSM such as Smack denies an AF_UNIX socket peer to receive an SCM_RIGHTS fd, the SCM_RIGHTS fd array will be cut short at that point, and MSG_CTRUNC is set on return of recvmsg(). This is highly problematic behaviour, because it leaves the receiver wondering what happened. As per man page MSG_CTRUNC is supposed to indicate that the control buffer was sized too short, but suddenly a permission error might result in the exact same flag being set. Moreover, the receiver has no chance to determine how many fds got originally sent and how many were suppressed.[1] Add a SO_RIGHTS_NOTRUNC option to UNIX sockets to enable more useful handling of LSM denials when receiving SCM_RIGHTS messages: instead of truncating the message at the first blocked fd, keep every fd slot and store the LSM errno in the blocked slot. The socket option is inherited by the child accept() socket if set on the listen() socket.

Pull misc vfs updates from Christian Brauner:
"Bigger cleanups:
- The lockref dead-count handling is tidied up.
The open-coded check for a count below zero as the dead marker
relies on information the caller should not have.
- make put_mnt_ns() leave mounts connected. Destroying a mount
namespace disconnected its mounts from their mount points. So a
file descriptor still open on the parent of a mount point could be
used to peek under it.
Locked mounts were already kept connected to prevent exactly that.
But a mount is only locked when its tree is copied across a user
namespace boundary. So a mount namespace set up by a privileged
component had no locked mounts and its mounts were disconnected.
Passing UMOUNT_CONNECTED keeps every mount connected and prevents
that bug.
- vfs_prepare_mode() passes S_IFDIR for directories. I meant to fix
that ago but didn't get to it. So now someone finally did it.
This kills the exception where the mode could be 0 when a directory
was created whereas every other creation operation passed it
explicitly already.
- move long delayed work for ufs, jffs2, hfsplus, hfs and affs from
the per-cpu system_long_wq to the new unbound system_dfl_long_wq.
None of that work relies on per-cpu state and the work item is
enqueued with queue_delayed_work() whose timer is global anyway. So
it may as well benefit from scheduler task placement.
Smaller fixes and cleanups:
- unlock_buffer() and journal_end_buffer_io_sync() use
clear_and_wake_up_bit()
- the pipe page pools are unified into a single per-pipe pool and the
extra wake_up(rd_wait) is limited to EPOLLET consumers
- eventpoll now computes its timer slack lazily in ep_poll()
- shrink_dcache_for_umount() keeps making progress on busy roots
- excess xarray nodes are freed in clear_inode()
- romfs detects hard link cycles
- the user path of nested backing files is fixed
- pidfd holds exec_update_lock around the namespace ioctl
- non-memcg-aware nr_cached_objects is skipped during memcg slab
shrink
- iomap_write_iter() always returns status
- mangle_path() is renamed to seq_mangle_path()
- inode timestamp accessors are annotated
- new regression test for pipe->poll_usage.

Pull binfmt updates from Christian Brauner:
"This contains a bunch of work for binfmt_misc. It fixes a bunch of
old bugs, reworks the locking, and then extends the format registry
so a binary type can be matched programmatically and its interpreter
computed per exec instead of being a fixed string recorded at
registration time.
This allows nixos and other to e.g., implement relocatable binaries
meaning the interpreter/dynamic loader can be determined
programatically, say found relative to the binary. The mechanism is
flexible and can support other policies:
- Handler lookup is now an rcu walk. An exec that matches no
binfmt_misc entry should now never write to a shared cacheline
- remove the VERBOSE_STATUS and USE_DEBUG compile time toggles
- convert the entry file to a seq_file which simplifies things quite
a bit and kills a lot of custom logic
- make flags proper enums
- rename struct Node to binfmt_misc_entry
- allow entries to be removed with unlink(2)
- Add the ability to attach bpf programs to binfmt_misc entries so
it's possible to dynamically choose the execution environment such
as the loader or interpreter on a per binary basis.
A handler is an instance of a binfmt_misc_ops struct_ops with a
->match() and a ->load() program. match() decides from the entry
lookup walk whether the handler applies under the same
registration-order. It can read file content as needed not only the
prefetched 256 bytes in bprm->buf.
load() then selects the interpreter and stages it through the new
bpf_binprm_set_interp(), bpf_binprm_set_interp_arg() and
bpf_binprm_set_flags() kfuncs.
Handlers are published in a registry keyed by the registering
task's user namespace and activated through the existing text
interface with a new 'B' type carrying the handler name:
echo ':origin:B::::nix:' > /proc/sys/fs/binfmt_misc/register
The permission and namespacing model is unchanged. Activating a
handler requires the same write access to an instance as any other
registration. A container mounting its own instance escapes the
host's entries exactly as before. The computed interpreter is
opened with open_exec() under the caller's credentials and goes
through full LSM vetting as the next binprm level. A program can
only ever redirect the caller to something the caller could exec
anyway.
- Two dispatch modes are added. So far the chosen interpreter owns
the whole process identity (argv[0], /proc/pid/cmdline,
/proc/self/exe all name interpreter information). So relocatable
find the dynamic linker instead. Also a binary passed to execveat()
as an inaccessible O_CLOEXEC fd cannot run at all and gdb trips
because AT_ENTRY and AT_PHDR do not match the exe file. So PIE
symbols are unrelocated.
This adds transparent dispatch which allows the interpreter to load
the binary through AT_EXECFD and leaves the argument vector exactly
as the caller built it and labels mm->exe_file and comm with the
binary. It also raises the AT_FLAGS_TRANSPARENT_INTERP aux vector
bit. The interpreter keeps control of mapping the binary.
The second mode is loader substitution. This allows a binary to be
executed natively and only the interpreter to be changed.
- Last, interpreters can be bound at registration time. Each
interpreter is opened by its own write with the credentials the
entry file was opened with. The program picks one per exec with
bpf_binprm_select_interp().
Ucounts are used to properly account for pre-opened interpreters
via /proc/sys/user/max_binfmt_misc_interpreters"

landlock: Add LANDLOCK_RESTRICT_SELF_NO_NEW_PRIVS
Add a landlock_restrict_self(2) flag to set the no_new_privs attribute of the calling thread only after enforcement of the ruleset: no_new_privs is set if and only if the call succeeds. This removes the need for a prior prctl(2) PR_SET_NO_NEW_PRIVS call and guarantees that a failed enforcement leaves the attribute unchanged. Because no_new_privs is set by the call itself, the no_new_privs / CAP_SYS_ADMIN requirement of landlock_restrict_self(2) is fulfilled by construction, and the related EPERM check is skipped. Unlike LANDLOCK_RESTRICT_SELF_LOG_SUBDOMAINS_OFF, this flag always requires a valid ruleset: with a ruleset_fd of -1, such a call would be nothing more than a Landlock-flavored prctl(2) PR_SET_NO_NEW_PRIVS, and there is no valid use case for setting no_new_privs (possibly with LANDLOCK_RESTRICT_SELF_TSYNC) without also enforcing Landlock restrictions. Rejecting these calls also keeps the option of giving them a meaning later. The attribute is only set past the last point of failure, just before committing the new credentials. When combined with LANDLOCK_RESTRICT_SELF_TSYNC, no_new_privs is set on the sibling threads as well, in their commit phase, with the same ordering. Bump the Landlock ABI version to 11, and include the minimal related test changes to keep the tests bisectable.

landlock: Require LANDLOCK_ACCESS_FS_MAKE_REG for whiteout creation
Whiteout objects are used in the upper layer of an OverlayFS to indicate that the file with this name does not exist in the unified view, even if it is present in one of the lower layer file systems. For the userspace implementations of OverlayFS (fuse-overlayfs), whiteout objects can be created from userspace as well: * mknod(2) with S_IFCHR and makedev(0, 0) * renameat2(2) with RENAME_WHITEOUT, creating the whiteout in the old place of the moved file. This commit guards whiteout creation in both of these cases with LANDLOCK_ACCESS_FS_MAKE_REG. Whiteout objects are *not* considered character devices and are not bound to a driver. LANDLOCK_ACCESS_FS_MAKE_REG describes the same permission class as a whiteout object: creating one is the only S_IFCHR creation that the VFS exempts from CAP_MKNOD, so it is as unprivileged as creating a regular file, while LANDLOCK_ACCESS_FS_MAKE_CHAR and LANDLOCK_ACCESS_FS_MAKE_BLOCK keep meaning the creation of devices that expose a kernel interface [1]. For the mknod(2) case, introduce a Landlock erratum. The creation of whiteout objects through mknod(2) was previously guarded using LANDLOCK_ACCESS_FS_MAKE_CHAR, and it is now guarded using LANDLOCK_ACCESS_FS_MAKE_REG. For the renameat2(2) case, fix a bug: Before this commit, renameat2(2) with RENAME_WHITEOUT would create a directory entry even when all LANDLOCK_ACCESS_FS_MAKE_* rights were denied. This does not affect normal renames within layered OverlayFS mounts: When doing a regular rename() on a mounted fuse-overlayfs, it is the fuse-overlayfs daemon that exercises renameat2() with RENAME_WHITEOUT, and only the Landlock domain of that daemon is checked there.

ALSA: uapi: Drop __bitwise and __force prefix
We've used __bitwise and __force for some integer parameters for sanity-checks via sparse, with a hope that it'll reduce the misuse or incorrect assignments. This worked in principle, but OTOH, it's been quite a PITA, making the code much uglier than its gain, too, because one had to cast with __force everywhere. Also, Rust-binding would skip those defines because of __force usage, which will become more pains in near future. So let's drop __bitwise and __force prefix usages. In this patch, we start cleaning up the UAPI headers at first. The former bit-wised typedefs are still kept for compatibility for now. As it's only markers for sparse, the changes are absolutely safe, per se. Only that we'll need to watch out more carefully about the variable usage for PCM format type, etc. Reviewed-by: Cezary Rojewski <cezary.rojewski@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://patch.msgid.link/20260812060557.80445-2-tiwai@suse.de |

ipv6: add ip6_del_rt_reason()
Add RTA_DEL_REASON and enum rt_del_reason to the rtnetlink uAPI, and add ip6_del_rt_reason(), which takes the reason a route is being deleted. It has no skip_notify argument: a caller that records a deletion reason wants the notification that carries it. The reason is unused for now. Subsequent patches propagate it to the deletion path and report it on RTM_DELROUTE.

ALSA: seq: Drop the dead struct snd_seq_event_bounce
The struct describes a bounce payload of an error code followed by the original event and its external data. No kernel has ever sent that. Before commit |
