Pull SCSI updates from James Bottomley:
"One new driver: leapraid (similar to mpi3mr but OK'd by Broadcom). The
usual suspects for driver updates (ufs, qla2xxx, smartpqi, zfcp, fnic,

- "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 2)" (David
Hildenbrand)
Remove the remaining pieces of CONFIG_HAVE_BOOTMEM_INFO_NODE,
performing some smaller cleanups around freeing of reserved vmemmap
pages on the way.
- "mm/damon: update probe hits for runtime parameter commits" (SJ Park)
Ensure 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.
- "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
reduces worst-case anon_vma lock hold times from over 500ms down to
under 2ms, preventing application freezes and latency spikes under
memory pressure.
- "mm: split a couple of headers from internal.h" (Mike Rapoport)
Split declarations related to mm_init, memblock, vmalloc and sparse
into new headers
- "KSM: use linear_page_index in collect_procs_ksm()" (xu xin)
Apply 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.
- "selftests/mm: avoid false failures in hugetlb and KSM tests" (Sayali
Patil)
Fix issues in the hugetlb and KSM MM selftest categories that can
report failures when the prerequisites for the tests are not
satisfied
- "mm/damon: introduce data attributes only monitoring" (SJ Park)
Introduce 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.
- "mm/hmm: Add mmap lock-drop support for userfaultfd-backed mappings"
(Stanislav Kinsburskii)
Extend 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.
- "mm: make VMA page offset handling more consistent" (Lorenzo Stoakes)
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
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.
- "mm/rmap: Refactor try_to_unmap_one" (Dev Jain)
Refactor 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.
- "Docs/ABI/damon: sysfs ABI document fixes and additions" (Song Hu)
Fix typos and fills in missing entries in the DAMON sysfs ABI
document
- "dax/kmem: atomic whole-device hotplug via sysfs" (Gregory Price)
Introduce 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.
- "mm: convert more vm_flags_t users to vma_flags_t" (Lorenzo Stoakes)
Continue 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.
- "Two small patches to clean up mm/mm_slot.h" (xu xin)
Refactor 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.
- "mm/damon/core: hide core-private struct fields" (SJ Park)
Clean 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.
- "mm/damon: unurgent fixes for infinite loop, NULL de-ref and races"
(SJ Park)
Address 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.
- "mm/page_alloc: fixes for free_pages_nolock() on RT/UP" (Brendan
Jackman)
Fix 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.
- "mm/page_alloc: couple of followups for recent cleanups" (Brendan
Jackman)
Clean up and update 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.
- "mm/mseal: further cleanups" (Lorenzo Stoakes)
Refactor and simplify 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.
- "mm/vmscan: fix swappiness=max and clean up per-node proactive
reclaim" (Ridong Chen)
Resolve reclaim behavior bugs and clean 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().
- "mm: mincore: misc cleanups" (Kefeng Wang)
Clean up and simplifies the mincore code. Most importantly, it
removes the historical special behavior that always reports VM_PFNMAP
pages as non-resident.
- "mm/huge_memory: drop dead split helper variants" (Kiryl Shutsemau)
Two trivial cleanups in the folio split API
- "mm/damon: fix uninitialized DAMOS field and kunit exec expectation
bugs" (SJ Park)
Resolve 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.
- "cleanup for stable_page_flags()" (Jinjiang Tu)
Clean up and refactor 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.
- "Batch unmap of uffd-wp file folios" (Dev Jain)
Extend 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.
- "mm/early_ioremap: clarify and clean up early_ioremap_reset()"
(Sang-Heon Jeon)
Clarify and clean 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.
- "mm: fix reclaim storms in defrag_mode" (Johannes Weiner)
Address 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.
- "zram: lockmap tweaks" (Sebastian Siewior)
Optimize and fix lockdep tracking for zram devices by consolidating
per-entry lockmaps and isolate lock classes across multiple instances
This 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.

Pull VFIO updates from Alex Williamson:
- 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)

encode_layoutstats_maxsz budgets XDR_QUADLEN(PNFS_LAYOUTSTATS_MAXSIZE),
i.e. 256 bytes, for the layoutupdate4 body written by the layout driver.
The flexfiles record can exceed that.
ff_layout_encode_ff_layoutupdate() emits, per data server, a netaddr4,
an nfs_fh4, two ff_io_latency4, an nfstime4 and a bool. A data server
whose filehandle is NFS_MAXFHSIZE bytes long already accounts for 132 of
those bytes, and the two ff_io_latency4 at 64 bytes each, the nfstime4
and the bool add a further 144, so the body passes 256 bytes before the
netaddr4 is encoded at all. encode_layoutstats() additionally writes
the deviceid4 and the layoutupdate4 lou_type word, neither of which the
macro accounts for.
The filehandle and the address are both chosen by the server, through
LAYOUTGET and GETDEVICEINFO, so it can drive the encoder past the
end of the send buffer. xdr_reserve_space() returns NULL once that
happens, and the two ff_layout_encode_io_latency() calls run with
dss_info->mirror->lock held, so a NULL return there leaves the lock
permanently held.
Raise PNFS_LAYOUTSTATS_MAXSIZE to 384 so that the record fits inside the
reservation.

Pull io_uring update from Jens Axboe:
"On top of the usual cleanups and fixes, the bigger items in here are:
- zcrx work, most of it centered around adding dynamic area
provisioning, plus a bunch of prep and cleanups leading up to it:
scale refilling with large pages, coalesce same-niov RQEs on
refill, separate the RQ head/tail cache lines and cache the RQ
tail, and rework the area creation locking.
- Fix the futex inflight accounting so that only private futex waits
are marked inflight, and don't mark wake requests as inflight at
all.
- Drop the custom iov copy in the buffer select prep and msg header
copy paths, using the generic helpers instead.
- Fix a folio size overflow in io_vec_fill_bvec(), and account the

The network and transport header fields in struct sk_buff are 16-bit
offsets from skb->head, and U16_MAX is reserved as the unset transport
header value. batadv_tvlv_call_handler() sets both fields from a received
multicast TVLV without checking whether the TVLV end is representable.
If the end offset exceeds the field's range, skb_set_transport_header()
truncates it so that the transport header precedes the network header.
The negative difference is then returned by skb_network_header_len() as
a large u32. batadv_mcast_forw_packet() consequently accepts an oversized
multicast tracker and accesses memory beyond the skb data.
Add skb_set_transport_header_careful(), an offset-aware counterpart to
skb_reset_transport_header_careful(), which validates the final
head-relative offset before assigning it. Use the new helper in
batadv_tvlv_call_handler() and reject unrepresentable TVLVs before
setting the network header.

Pull nfsd updates from Chuck Lever:
- CB_NOTIFY support for 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)
- Continued netlink work
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 (Jeff Layton)
- Remove SUNRPC service thread pool mode selection
Per node 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.
- Bug fixes, clean-ups, and small optimizations:
- async COPY offload rework (Jeff Layton)
- more use-after-free fixes in the NFSv4 state revocation paths
- percpu counter contention removed from the reply cache and IO
accounting
- a long list of hardening fixes (Chris Mason)
Sincere thanks to all contributors, reviewers, testers, and bug
reporters who participated in the v7.3 NFSD development cycle.

mlx5_query_vport_max_tx_speed() was introduced to serve the
query_port_speed path, which uses max_tx_speed == 0 when port is down.
This is incorrect for callers that need the actual configured speed
regardless of vport state, such as modify-vport-state helpers
that must preserve the speed across state transitions.
Move this logic to the caller function in the verb flow and let
mlx5_query_vport_max_tx_speed() return the raw firmware value
unconditionally.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext updates from Tejun Heo:
"Most of this cycle completes the enqueue-path support for hierarchical
sub-scheduling, which makes sub-scheduler support feature complete: a
root BPF scheduler can now hand a cgroup subtree over to a nested
sub-scheduler together with revocable CPU grants, and the
sub-scheduler owns all scheduling decisions for its tasks on those
CPUs.
Development volume was high and a number of changes plugging holes in
the new support landed late in the cycle. Also included are core
scheduling fixes that were completed too late for the v7.2 release and
are routed through this pull request.
Sub-scheduler CPU delegation:
- Parent schedulers now grant and revoke per-CPU capabilities
(enqueueing, preemption, CPU frequency control) on their children,
enforced on every path a scheduler can reach a CPU through.
Previously only dispatching could be delegated; this lets
sub-schedulers fully schedule their CPUs.
- Rescue execution: a task whose scheduler doesn't have access to the
CPUs the task needs to run on starved until the watchdog ejected
the whole scheduler. The kernel now runs such tasks directly on a
small bandwidth budget, turning a scheduler-killing failure into
bounded degradation.
- Cgroup integration: tasks migrating across a sub-scheduler boundary
weren't re-homed to the new owner, causing wrong-scheduler
scheduling and a use-after-free. Sub-schedulers now take over their
cgroup subtree and receive its cgroup callbacks.
- Arena objects now cross the kernel/BPF boundary as typed pointer
arguments, translated transparently by the BPF tree's new arena
argument support, replacing untyped arguments with manual
translation.
- scx_qmap now demonstrates full hierarchical sub-scheduling.
Other fixes and updates:
- Robustness improvements: the abort path is now NMI-safe, fixing
deadlocks when errors are raised from NMI context and making
hardlockup recovery direct. Reenqueue loops that could monopolize a
CPU ahead of the watchdog now eject the offending scheduler, and
stalls are blamed on the scheduler actually responsible.
- Hardening: BPF-writable arena memory is validated before kernel
use, and task slice and vtime writes got explicit synchronization
rules, closing corruption vectors open to buggy or malicious
schedulers.
- Core scheduling: sched_ext dispatching can drop the rq lock inside
the core-wide pick, which let interleaving selections corrupt each
other's state and hard-hang the machine. The selection now restarts
when the lock was released. The task ordering callback was also
invoked with its arguments swapped, and the default ordering is
updated to work across sub-scheduler boundaries. The fixes are
marked for stable.
- Other fixes headed for stable: a task init leak on fork failure
during enable, tooling compat macros that silently failed to detect
newer kernels, and a crash on reenqueueing against a destroyed
dispatch queue.
- Tooling: scx_pair moves off deprecated callbacks, and the
deprecated scx_bpf_cpu_rq() kfunc is removed"

Pull cgroup updates from Tejun Heo:
- Attach path bug fixes: migrations spanning multiple source or
destination cpusets were mishandled, most visibly leaving thread
affinities stale when the controller is disabled in a threaded
subtree. Configuration writes could also race an in-flight attach and
apply stale state, and the deadline task count could get corrupted by
concurrent updates, skewing SCHED_DEADLINE admission decisions.
- Memory binding bug fixes: which node masks get applied differed
between the binding update paths, and tasks cloned with
CLONE_INTO_CGROUP skipped rebinding entirely. Rebinding also now runs
once per process instead of repeating for every thread sharing the
mm.
- Overhead removals with no behavior change: CPU hotplug iterated tasks
of cpusets that just inherit the parent's effective masks, and the
slab-spreading task flag was still being maintained although the SLAB
allocator that consumed it is long gone.
- Data-race annotations for benign races so that KCSAN reports stay
meaningful, selftest coverage for the fixes above along with
flakiness and portability fixes, and documentation corrections.

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
- Continue converting getsockopt callbacks in a number of protocols
to iov_iter
Ethernet:
- Merge initial CXL support for AMD/Solarflare NICs (shared branch
with the CXL tree)

Pull bpf updates from Daniel Borkmann:
"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

x86's efi_crash_gracefully_on_page_fault() ends in an infinite
schedule() loop so the kworker that faulted in firmware never runs
efi_rts_wq again. A later change needs the same "park this worker
forever" primitive on the runtime service timeout path, so factor the
loop into a shared efi_rts_park_worker() and call it from the x86
page-fault handler.
No functional change.

A read from /proc/sys/kernel/sched_rt_runtime_us leads to backtrace due
to missing cpu_hotplug_lock with CONFIG_CPUSETS=n. The callchain is
sched_rt_handler() -> partition_sched_domains() -> sched_cache_set() ->
static_key_enable_cpuslocked(&sched_cache_present).
sched_cache_set() itself is also invoked from sched_init_domains() which
is early during the boot, holding just the sched_domains_mutex_lock().
Here is no warning because it happens before user space is running (and
hotplug operations are not possible).
There is also sched_cache_active_set() which acquires the hotplug lock
before invoking any of the _cpuslocked() functions.
This is only a problem with CONFIG_CPUSETS=n because in the =y case the
other implementation of rebuild_sched_domains acquires the CPU-hotplug
lock.
Acquire CPU hotplug lock before in rebuild_sched_domains(), before
partition_sched_domains() is invoked for the CONFIG_CPUSETS=n case.

In gicv5_irs_of_init(), an IRS is set-up using of_io_request_and_map() to
request its memory region (corresponding to the configuration frame) and
map the IRS configuration frame.
On gicv5_irs_of_init() failure, the driver unmaps the IRS iomem region but
does not release the requested memory region leaving it allocated in the
iomem resource tree.
Fix it by releasing the iomem region on gicv5_irs_of_init() probe failure.
Likewise, on both OF and ACPI driver init failure, IRS iomem regions are
requested but never released in gicv5_irs_remove().
Stash a copy of the IRS iomem region in a struct resource in
struct gicv5_irs_chip_data and use it to release the requested region in
gicv5_irs_remove() if the driver probe fails.

Pull integrity updates from Mimi Zohar:
- TPM initialization is sometimes delayed until deferred_probe_initcall
Since ordering is not guaranteed within the same initcall level, IMA
may initialize before the TPM and fall back to TPM-bypass mode. A new
config option, CONFIG_IMA_INIT_LATE_SYNC, allows those building the
kernel to defer IMA initialization to late_initcall_sync, accepting
the integrity risk of missing early measurements in exchange for
avoiding TPM-bypass mode.

policy, closing a gap in integrity measurement coverage

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Expose btf_ids to trace events
In order to allow BPF programs to attach to system call trace events
(which are actually pseudo trace events built on top of raw_syscall
events), expose the BTF ID of the events. This will allow BPF
programs better precision in attaching to events.
- Use "u64" to assign to hist_field->type
Instead of using kstrdup("u64", GFP_KERNEL) to assign the
hist_field->type, just point it to "u64" instead. The
hist_field->type is freed via kfree_const().
- Replace kmalloc()/strcpy() with kstrdup() for trace_printk
Instead of having two calls to copy the module format string, just
use kstrdup().
- Use __free() in trace event histograms and triggres where possible
- Use seq_buf in trace event code instead of strcat()
Instead of calculating the size of the buffer to use and filling it
with strcat(), use the seq_buf infrastructure that takes care of
making sure not to overflow the string size.
- Reject invalid preemptirq_delay_test CPU affinity
The preempt_delay_test module can take an invalid CPU affinity mask
and create confusing output. Simply have the module reject invalid
affinity masks.
- Prevent division by zero in ftrace_ops sample module code
If the ftrace_ops sample module code receives the module parameter
nr_function_calls set to zero, it can cause a division by zero error.
- Warn when an event dereferences a parameter in TP_printk()
On boot up and module load, the trace event TP_printk() is scanned
for possible bugs. As the TP_printk() code is executed when the user
reads the "trace" file and processes the data written when the
trace_event executed, the data it reads can be literally days old.
The scan currently checks for dereferencing printk formats like
"%pI6". But it does not check if the parameters themselves have a
dereference like:
TP_printk("offset %08x: value %08x",
(u32)(__entry->addr - __entry->edma->membase), __entry->value)
__entry represents the pointer to the event on the ring buffer. The
__entry->edma->membase is dereferencing a pointer on the ring buffer
to find membase, but the __entry->edma may no longer be a valid
pointer.
Warn on this case too.
- Replace some strcpy() with strscpy()
- Clean up mmiotrace events to use assign_type() macro
The assign_type() macro makes sure the event type is indeed the type
that is being parsed. The mmiotrace trace was written before that
macro was created so it just simply typecasted the pointer.
Replace the typecasting with the macro.
- Have the ENUM processing to numbers only process what is added
The code that converts ENUMs to their numbers in the trace events
scanned all events to do the processing. This was true when a module
was loaded too. That is, instead of processing just the events for
the module, it processed *all* events. Even the builtin ones that
were processed at boot up.
Add a check for the event->module matching mod if it is a module
before processing it.

git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core
Pull driver core updates from Danilo Krummrich:
"container_of:
- Apply typeof_member(), remove the local __mptr variable to
eliminate variable shadowing warnings on nested container_of()
calls, and remove unnecessary parentheses
core:
- Add driver name to probe debug print for initcall_debug
- Avoid repeatedly printing the same 'Fixed dependency cycle' log
- Unwind device_add() on attribute creation failure in
attribute_container_add_class_device()
- Remove statistics group if encryption group creation fails in
transport_add_class_device()
debugfs:
- Fix lockdown check for mmap_prepare()
- Warn if file creation failed due to uninitialized debugfs
device property:
- Implement fw_devlink support for software nodes by adding
software_node_add_links(), which creates fwnode links from
DEV_PROP_REF properties to enable automatic probe ordering. Add
kunit-managed fwnode helpers and test coverage
- Fix infinite loop in fwnode_for_each_child_node() when the
secondary fwnode has more than one child. Add test cases
- Fix out-of-bounds access in software_node_get_reference_args() when
called with index -1 (UINT_MAX)
- Refactor to use RAII approach with __free()
- Add Bartosz Golaszewski as software node reviewer
firmware loader:
- Fix race where a sysfs fallback request can complete before being
queued as pending, leading to a use-after-free on the next fallback
request
- Reject 0-size built-in firmware and fail the build on empty
firmware files in CONFIG_EXTRA_FIRMWARE
kobject:
- Provide __KOBJ_ATTR() and __KOBJ_ATTR_RO/WO() initialization macros
and allow the constification of kobject attributes, enabling them
to reside in read-only memory
platform:
- Provide platform_device_set_of_node(), platform_device_set_fwnode(),
and platform_device_set_of_node_from_dev() helpers that encapsulate
firmware node reference counting for dynamically allocated platform
devices
Convert all in-tree users that manually assigned dev.of_node or
dev.fwnode, fixing a pre-existing refcount bug in powermac. Switch
to counting references of all firmware node types, not only OF
nodes
- Unify the release path for dynamically allocated platform devices
by removing platform_device_release_full(). Amend the fwnode setter
API contract to warn if a primary software node is overwritten. Add
KUnit tests for correct software node removal on device
unregistration
Rust:
- Auxiliary:
- Add registration_data_with() closure-based API for invariant
ForLt types
- Debugfs:
- Migrate BinaryWriter and BinaryReaderMut trait requirements
from kernel::transmute traits to zerocopy traits
- Device:
- Add BoundInternal device context and InternalBoundContext trait
for bus abstractions that need internal access to a bound
device.
- Make the lifetime on Core and CoreInternal invariant to prevent
coercion to shorter lifetimes
- Devres:
- Fix race between concurrent revokers where the losing revoker
could return before the winning revoker finished dropping the
inner data, causing use-after-free.
- Ensure revocation is complete before the device finishes
unbinding by making the synchronization bidirectional.
- Add DevresLt<F: ForLt>, a wrapper around Devres that shortens
'static back to the caller's borrow scope. Implement ForLt and
CovariantForLt for Bar, IoMem, and ExclusiveIoMem
- Driver:
- Switch from index-based to pointer-based device ID info lookup,
storing static references in driver_data. Centralize device ID
handling in device_id.rs, removing the open-coded ACPI/OF
matching logic and duplicate ID table from driver.rs
- I/O:
- Make I/O regions typed (with a dynamically-sized Region type
for the existing untyped case), create view types representing
subregions of a mapped I/O region, and add io_project!() for
safely creating subviews.
- Split Io into a base trait (IoBase) and an extension trait (Io)
with a blanket implementation, preventing implementers from
overriding provided methods that unsafe code relies on.
- Add a SysMem backend for shared system memory with volatile
access, and make Coherent implement Io via an I/O view type.
Add IoSysMap as sum type of Mmio and SysMem. Add copying
methods (memcpy_{from,to}io()) and read_val()/write_val() for
typed access.
- Replace dma_read!()/dma_write!() with io_read!()/io_write!()
for primitives and copying methods for aggregates; drop the old
macros. Convert nova-core to use I/O projection.
- Fix internal shortcut rule dispatch in the register!() macro,
remove unused rule arguments, and use path fragments for alias
destinations
- IRQ:
- Make irq::Registration compatible with lifetime-bound drivers
by removing the 'static bound on Handler/ThreadedHandler and
replacing Devres<RegistrationInner> with direct
request_irq()/free_irq() calls. Handlers can now directly own
lifetime-bound device resources
- PCI:
- Convert IrqVectorRegistration to a lifetime-annotated owning
type, giving drivers explicit control over the allocation
lifetime. IrqVector embeds a resolved IrqRequest, making the
conversion infallible. Remove the redundant
request_irq()/request_threaded_irq() wrappers from pci::Device.
- Add pci_irq_type() C helper and expose it via irq_type() on
IrqVectorRegistration and IrqVector, returning PCI_IRQ_MSIX,
PCI_IRQ_MSI, or PCI_IRQ_INTX.
- Mark pci::Device refcount methods inline
- Serdev:
- Add Rust abstractions for the serial device bus, including
serdev::Driver trait, serdev::Device wrapping struct
serdev_device, and serdev::Adapter implementing
RegistrationOps. Includes a sample driver. Markus Probst takes
over as serdev maintainer for both C and Rust code
- Misc:
- Split ForLt into a base trait (providing the Of<'a> GAT) and an
unsafe CovariantForLt subtrait guaranteeing covariance,
enabling invariant types (e.g. those containing Mutex<&'bound T>)
to participate in the ForLt abstraction.
- Fix Coherent read past EOF returning -ERANGE instead of zero.
- Fix firmware example UB by avoiding null-pointer ARef
misc:
- Avoid iattr allocation in kernfs listxattr by using
kernfs_iattrs_noalloc().
- Unregister SoC bus on early device registration failure.
- Remove unused DMA_FENCE_TRACE Kconfig symbol.
- Fix /sys/module path in comment.
- Refactor ISA bus init to remove nested blocks.
- Remove redundant nodemask clears in numa_init().
- Add kernel-doc for fwnode_operations and sys_soc.h, mark
internal property data as private for kernel-doc, and add
property.h/fwnode.h to driver-api infrastructure docs.
- Add MAINTAINERS entry for sys_soc.h"

Pull spi updates from Mark Brown:
"Along with a lot of driver specific work we've got a couple of core
features here. The bigger one is that we've now got support for
instantiating devices from sysfs similarly to how it's already done
for I2C, this is used with development boards with non-enumerable
expansion headers since SPI devices need to be manually specified. We
also have support for the DQS signal on higher end flash devices.
- Support for instantiating devices from sysfs, useful for
development boards with non-enumerable plugin modules, from
Vishwaroop A.
- Support for DQS in spi-mem, an additional signal used by flash
devices to avoid clock skew from Miquel Raynal.
- Support for more advanced SPI modes on DesignWare controllers from
Sudip Mukherjee.
- Changes from Jisheng Zhang to update to modern methods of
specifying the PM callbacks.
- Fixes for DMA mapping error handling, plus KUnit tests for this,
from Honghui Jiang.
- Substantial cleanup and performance work in the nxp-spi driver.
- Support for Microchip LAN969x, Nuvoton MA35D1 QSPI, Qualcomm
SA8255p and SA8797P, and StarFive JHB100 SFC"

Pull regulator updates from Mark Brown:
"This is a relatively quiet release for the regulator API, we've had no
major core work and not really that much driver work either. There's a
bunch of activity, including several new devices, but nothing hugely
remarkable here.
- Reworking of the mode handling in the max14577 driver to fix issues
with collisions with enables
- Support for onsemi FAN53555BUC23X, Qualcomm IPQ9650, PM4125 VBUS
and PM8150B and Unisoc SC2730"
