Pull RISC-V updates from Paul Walmsley
- Add initial definitions and discovery for the Smcsrind, Sscsrind,
Smcntrpmf, Ssccfg, Smcdeleg, Zicclsm, Ziccamoa, Ziccif, Ziccrse,
Za64rs, and Ssqosid RISC-V ISA extensions
- Improve the RISC-V update_mmu_cache_range() implementation by using
flush-by-ASID, enabling performance improvements on
microarchitectures that support related optimizations; and by taking
advantage of the Svinval RISC-V ISA extension on microarchitectures
that support it
- Shrink CFI shadow stack allocation further (to 512MB) to save virtual
address space (and physical memory on systems with strict overcommit
policies)
- Add initial CPU context switch support for QoS tagging (Ssqosid)
- Change our vector misaligned access speed test code to be
synchronous, avoiding a bunch of bugs related to unnecessary
asynchronicity
- Enable ARCH_HAS_ACPI_TABLE_UPGRADE for RISC-V to help with ACPI table
debugging (similar to ARM64 and x86)
- Extract vDSO section offsets at build time, rather than run time, to
avoid the boot time overhead
- Use assembler directives to control the use of instructions from the
RISC-V ISA extensions Zacas and Zabha, rather than compiler -march
flags that could affect the whole kernel (similar to ARM64)
- Add a kselftest for kprobes support for the c.jal instruction on
RISC-V
- When UEFI runtime services are available, use them to restart and
power off
- Fix ARCH_HAS_ACPI_TABLE_UPGRADE for RISC-V by adding a missing
include file to the ACPI code
- Move contiguous DMA memory reservation later in the boot, to ensure
that the correct global and per-node pools are allocated when
CONFIG_CMA_SIZE_PERNUMA is enabled
- Disallow probes on breakpoint handlers to avoid recursing
indefinitely into do_trap_break()
- Patch the compat vDSO during runtime alternatives processing, not
only the standard vDSO
- Remove some leftover XIP support elements missed by commit
9b3a2be84803 ("riscv: Remove support for XIP kernel")
- Fix broadcast timer switching in ACPI LPI power states by
implementing a RISC-V version of arch_get_idle_state_flags()
- Miscellaneous fixes, including: vDSO makefile simplification; marking
our default_power_off() as __noreturn; error path fixes in the PMU
SBI perf driver; RISC-V extension capitalization consistency; the use
of BIT() macros in one of our include files; and some documentation
fixes

Jiri Olsa reports slowdown of tracing_multi benchmark that allocates huge
number of trampolines [1].
The slowdown caused by extra protection changes in execmem_alloc_rw() and
execmem_free().
With ROX caches enabled, all execmem allocations except EXECMEM_MODULE_DATA
are ROX after the allocation. execmem_alloc_rw() temporarily sets them to
W+NX and execmem_free() resets them back to ROX.
The only user of bpf_jit_alloc_exec_rw() is x86::arch_bpf_trampoline_size()
that only needs a temporary writable buffer in the modules address space.
On x86 executable memory and module data are constrained to the same
address range, so x86::arch_bpf_trampoline_size() can directly use
execmem_alloc(EXECMEM_MODULE_DATA)
Replace the call to bpf_jit_alloc_exec_rw() with a call to
execmem_alloc(EXECMEM_MODULE_DATA) in x86::arch_bpf_trampoline_size() and
drop bpf_jit_alloc_exec_rw() helper.
Fixes: 5bf02dbf39fa ("bpf, x86: Make sure allocation in arch_bpf_trampoline_size() is writable")

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...

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,

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.

After commit dfc256dac54c ("calibrate: Rework delay timer calibration"),
certain ARM configurations (such as multi_v5_defconfig) hang during
boot. The use of read_current_timer() in arch/arm's get_cycles() was
improperly converted to delay_read_timer(), resulting in get_cycles()
returning 0 even when the timer has been read or an uninitialized stack
value when delay_read_timer() returns false.
Flip the branches of the ternary condition to fix get_cycles().

With GICv5, timer PPIs use architecturally defined IDs, and therefore
we require userspace to use the architected IDs too. We perform this
validation in timer_irqs_are_valid(), which validates the configured
PPI after claiming it with kvm_vgic_set_owner(). This is obviously the
wrong order, and could both result in a NULL pointer dereference for
an ID >= 64 and in an incorrect ownership claim.
Switch the order to first validate the PPI before setting the
owner. This both prevents an invalid GICv5 timer PPI from reaching the
IRQ lookup, and avoids claiming an IRQ for a timer configuration that
will be rejected.

GICv5 supports up to 128 PPIs, but KVM currently implements only the
first 64, which contain the architected PPIs it supports.
An encoded PPI with an ID outside that range passes irq_is_ppi(),
which only checks the encoded interrupt type. vgic_get_vcpu_irq()
therefore looks it up in private_irqs[], where array_index_nospec()
clamps the out-of-range index to zero and aliases PPI 0.
Include the supported PPI range in irq_is_ppi() so that KVM interfaces
reject unsupported PPIs. Also reject an out-of-range PPI in the lookup
as a safeguard against callers bypassing the predicate.

For a non-GICv5 VM, SPI interrupt IDs include the private-interrupt
offset, while KVM's SPI array is indexed from zero. The lookup applies
array_index_nospec() to the absolute interrupt ID and subtracts the
private-interrupt offset afterwards.
On a speculative bypass of the range check for an interrupt ID below
the private range, the clamp preserves the small absolute value and
the subtraction underflows to an out-of-bounds SPI array index.
Convert the interrupt ID to a zero-based index into the SPI array
before applying array_index_nospec(). This way, we ensure that we
clamp to a reachable SPI ID, rather than an out-of-range SPI index.

vgic_set_kvm_info() allocates gic_kvm_info for use by
kvm_vgic_hyp_init(). When a maintenance interrupt is mandatory but not
provided, kvm_vgic_hyp_init() returns -ENXIO before reaching the
common cleanup path, leaking said allocation.
Route this error through that cleanup path so that gic_kvm_info is
freed and the global pointer is cleared.

When running with hVHE enabled, ___kvm_hyp_init() calls
__kvm_init_el2_state() on the CPU initialisation path during onlining
and resume from suspend.
In order to avoid clobbering the link register across this call, it is
stashed away in the 'tmp' member of 'struct kvm_nvhe_init_params',
however this save/restore operation is performed with the stage-1 MMU
disabled at EL2 and therefore gives rise to coherency problems because
the field is not aligned or padded to the CWG. For example, a cacheable
write to a physically-adjacent structure sharing the same cacheline
could lead to an eviction and subsequent write-back, overwriting the
saved LR while the incoming CPU is executing __kvm_init_el2_state().
Save the lr in far_el2 and remove the 'tmp' member from
'struct kvm_nvhe_init_params' altogether.

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

Pull gpio updates from Bartosz Golaszewski:
"GPIO core:
- extend the gpio-regmap abstraction layer with more features
allowing users to override configuration setting, translate
register values and masks and enable/disable interrupts
- extend GPIO kunit tests with suites verifying probe ordering by
software node devlink support and software node hogs
- shrink GPIO kunit initialization code
- coding style updates (remove commas from sentinels where
applicable)
- with all users now converted treewide to using real firmware node
links for software node GPIO lookup: remove the deprecated
label-matching mechanism from from GPIO core
- drop redundant return value check of nonseekable_open() in
gpiolib-cdev
- use IRQ trigger helpers where applicable
Driver updates:
- refactor error paths and logging in gpio-nomadik

Pull ARM SoC platform updates from Arnd Bergmann:
"The 32-bit Arm platforms are a bit more interesting this time: I
refreshed an earlier series to mark code as deprecated that does have
the tendency of getting in the way of cleanups and new features but
has close to zero users. Among these are:
- 22 of the remaining 28 legacy board files that predate the current
devicetree based descriptions, using old chips from Intel and
Marvell. The remaining six board files are for TI OMAP1 and Samsung
s3c64xx chips and all still have known users.
- support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25
machines based on these. These all use devicetree but the CPU
support causes disproportional work. Most of them are just
reference boards, the notable exceptions being the Nokia N800/N810
tablet and the Buglabs BUG platform.
- be8, be32, oabi and iwmmxt userspace binaries, which were mostly
associated with the platforms now scheduled for removal and are
increasingly problematic to support with modern toolchains.
Nothing is actually removed at this point, to ensure that any
remaining users continue to have the 7.3-LTS for a while longer.
Patches for removal are currently being tested.
Other updates include a continued work to convert GPIO number based
interfaces to descriptors, a patch to restore little-endian mode on
the one Arm platform (ixp4xx) that only worked in big-endian mode
recently, and some minor cleanups and bugfixes"

- The Apple platform gains support for M3 Pro, Max and Ultra SoC,
following the basic M3 support from 7.2.
- Samsung Exynos 1580 is a high-end mobile phone SoC from 2024
- Canaan K230 is a RISC-V based 64-bit AI SoC, based on the earlier
K210 chip
- Sophgo SG2000 is a mixed Arm/RISC-V chip that was already supported
using the Arm core but is now also added for RISC-V along with
several other variants of the cv18xx series
In terms of newly added machines we have reference platforms for all
the chips above, plus
- Only four 32-bit Arm boards: two older phones and two older
industrial/embedded boards; using Allwinner, Qualcomm and Rockchip

Pull timer and timekeeping core updates from Thomas Gleixner:
- 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 hard 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

Pull treewide timer related cleanups from Thomas Gleixner:
- Remove the leftover CLOCK_TICK_RATE which has been scheduled for
removal more than a decade ago along with some now empty asm/timex.h
files.
- Consolidate delay timer calibration
The construct of having a define in a header requires that
architectures provided asm/timex.h for no reason. Also the function
name for reading the delay timer is confusing at best.
Use a config switch to enable that functionality and rename the
function to delay_read_timer() to make the purpose clear.
This removes some more now empty asm/timex.h files as well.

Pull generic entry code updates from Thomas Gleixner:
- Make syscall user dispatching configurable
Not all architectures can makes use of syscall user dispatching.
Allow them to disable the feature completely.
- Consolidate stack randomization for the generic entry code and the
architectures using it.
Stack randomization on syscall entry was sprinkled throughout the
architecture specific low level entry code and in some cases at the
wrong points, e.g. before establishing state, which violates the
non-instrumentable constraints of that code.
Clean this up by integrating stack randomization into the generic
entry code helpers so that it is invoked at the earliest possible
point right after establishing state and converting all generic entry
code using architecture over.
- Clean up the syscall number handling in the generic entry code. It
works correctly for architectures which have a separate return value
storage in pt_regs, but fails to distinguish the case where user
space handed in -1 as syscall number from the case where the entry
code rejects it by returning -1 to the callers. Aside of that the
return value functionality of those interfaces is not really
intuitive.
Fix this by separating the decision to reject a syscall (user
dispatch, ptrace, seccomp ...) from the potential modification of the
syscall number through these mechanisms.
This solves most of the problems for architectures which do not have
a separate return value storage in pt_regs except for the case where
a tracepoint has a BPF script or a probe attached which overwrite
both the syscall number and the return value. But that's a problem
which cannot be solved in the generic code, that only can be
addressed by separating the storage model in the affected
architectures.
