gpio: tegra: do not call pinctrl for GPIO direction
tegra_gpio_direction_input() and tegra_gpio_direction_output() already
program the GPIO controller direction registers directly. The additional
pinctrl_gpio_direction_input/output() calls do not add a Tegra pinctrl
operation, because the Tegra pinmux ops provide GPIO request/free
handling but no gpio_set_direction hook.
The extra call still enters the pinctrl core and takes pctldev->mutex.
Shared GPIO users can call the direction path while holding their
per-line spinlock, so this otherwise redundant pinctrl direction call can
sleep in an atomic context.
This was found by our static analysis tool and then confirmed by manual
review of tegra_gpio_probe(), the Tegra GPIO direction callbacks and the
Tegra pinctrl ops. The reviewed path has a default non-sleeping
struct gpio_chip while the direction callback still enters the pinctrl
mutex path.
A directed runtime validation kept the same non-sleeping chip registration
and drove:
gpio_shared_proxy_direction_output()
gpiod_direction_output_raw_commit()
tegra_gpio_direction_output()
pinctrl_gpio_direction_output()
Lockdep reported a sleep-in-atomic warning with the shared GPIO spinlock
held and pinctrl_get_device_gpio_range() plus tegra_gpio_direction_output()
on the stack.
Do not mark the whole chip as can_sleep to paper over this: can_sleep
describes whether get()/set() may sleep, and Tegra value access is MMIO.
Remove the redundant pinctrl direction calls and keep pinctrl involvement
in the existing request/free path.

gpiolib: initialize return value in gpiochip_set_multiple()
gpiochip_set_multiple() falls back to setting lines one by one when the
chip does not provide set_multiple(). If the fallback path receives an
empty mask, the loop is skipped and ret is returned without being
initialized.
Initialize ret to 0 so an empty mask is treated as a successful no-op.

NFSD 7.2 Release Notes
Jeff Layton wired up netlink upcalls for the auth.unix.ip and auth.unix.gid caches in SunRPC and the svc_export and nfsd.fh caches in NFSD. The new kernel-user API is more extensible and lays the groundwork for retiring the old pipe interface. The default NFS r/w block size rises to 4MB on hosts with at least 16GB of RAM, reducing per-RPC overhead on fast networks. Smaller machines keep their previously computed default, and the value remains tunable through /proc/fs/nfsd/max_block_size. Chuck Lever converted the server's RPCSEC GSS Kerberos code to the kernel's shared crypto/krb5 library. The conversion retires and removes SunRPC's bespoke implementation of Kerberos v5, but keeps RPCSEC GSS-API. Continuing the xdrgen migration that converted the NLMv4 server XDR layer in v7.1, Chuck Lever converted the NLM version 3 server-side XDR layer from hand-written C to xdrgen-generated code. As with the NLMv4 conversion in v7.1, the goals are improved memory safety, lower maintenance burden, and groundwork for generation of Rust code for this layer instead of C. Chuck Lever fixed an issue where lingering NFSv4 state pins a mounted file system after it is unexported. A new netlink-based mechanism can now release NLM locks and NFSv4 state by client address, by filesystem, and by export. Now an administrator can quiesce an export cleanly before unmounting it. The remaining patches are bug fixes, clean-ups, and minor optimizations, including a batch of memory-leak and use-after-free fixes in the ACL, lockd, and TLS handshake paths, many of them reported by Chris Mason. Sincere thanks to all contributors, reviewers, testers, and bug reporters who participated in the v7.2 NFSD development cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmox5BcACgkQM2qzM29m f5eFJQ//QlyZCt0BlzeBrGHJB41yrMZkZGSJsPaZPfvNnjIQPwd6WH3d6i1vygvC HgC+KTF/8LLuFx14m17M6FBCujixNoknMLyp74vRPZOSCoXilP/jzlDoVWwgwv73 E0AkKXyij1QFToIh7NP/ClX+Zpc9yoCR3/RWri7ud400z1mlvFBk8NA7E6pb+AzT 89lKFgkubSQVnHFRdIAgb3G/AkZzt35O6hzPA6thtwkb8MS2knE27L9HNc2InQ/K 71QjQj09052tcXOJRHlg7Xj6AeCyPteCqxsA03qMo2mmqRiSBVV+5y6czawxdHk8 yt9cDloUu+ZynhH4qktv3i8lX7dPcYNfIcMora71LAswDE5Ud3c/EG6zleA5DnzX cgUaS8VkbfLyHAlvPRl9DroizsBgrr/qjuwUqewoY/wJCpyEBtCGRxLKI0MS2Ivo BvgdXE74uCyOGZ2EYOqaocGejMtXt1GGpf2Wj5/jyDDUABEhwTptoTIlbBcWQbf6 7ZRlxjwx7kaMMtmag0ZEhkh42ujoHF3NzNDDD4hY1M6twgF+0uofJPLb5eK4JZak FDKV38iiwqq2/bWOKGnaFQBV1Hn/0569rxFku2Z0O+wWNBXhiZ5wezw84GoYaCt/ AYSDFYnI4FOrHurdmgZUyr04W2toXWN6mV3IqbDIIx5eXyWEKvU= =xAeq -----END PGP SIGNATURE----- Merge tag 'nfsd-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Jeff Layton wired up netlink upcalls for the auth.unix.ip and auth.unix.gid caches in SunRPC and the svc_export and nfsd.fh caches in NFSD.

Many AI driven bug fixes, and several big driver API cleanups
- Driver bug fixes and minor cleanups in mlx5, hns, rxe, efa, siw, rtrs,
mana, irdma, mlx4. Commonly error path flows, integer arithmetic
overflows on unsafe data, out of bounds access, and use after free
issues under races.
- Second half of the new udata API for drivers focusing on uAPI response
- bnxt_re supports more options for QP creation that will allow a dv
path in rdma-core
- Untangle the module dependencies so drivers don't link to ib_uverbs.ko
as was originall intended
- Provide a new way to handle umems with a consistent simplified uAPI and
update several drivers to use it. This brings dmabuf support to more
places and more drivers
- Support for mlx5 rate limit and packet pacing for UD and UC

gpio: eic-sprd: use raw_spinlock_t in the irq startup path
sprd_eic_irq_unmask() enables the GPIO IRQ and then updates controller
state through sprd_eic_update(), which takes sprd_eic->lock with
spin_lock_irqsave(). The callback can be reached from irq_startup()
while setting up a requested IRQ. That path is not sleepable, but on
PREEMPT_RT a regular spinlock_t becomes a sleeping lock.
This issue was found by our static analysis tool and then manually
reviewed against the current tree.
The grounded PoC kept the request_threaded_irq() -> __setup_irq() ->
irq_startup() -> sprd_eic_irq_unmask() -> sprd_eic_update() carrier and
used the original spin_lock_irqsave(&sprd_eic->lock) edge. Lockdep
reported:
BUG: sleeping function called from invalid context
hardirqs last disabled at ... __setup_irq.constprop.0 ... [vuln_msv]

__setup_irq.constprop.0+0xd/0x30 [vuln_msv]
Convert the Spreadtrum EIC controller lock to raw_spinlock_t. The
locked section only serializes MMIO register updates and does not contain
sleepable operations, so keeping it non-sleeping is appropriate for the
irqchip callbacks.

Convert the SCH controller lock to raw_spinlock_t. The same lock is
also used by the GPIO direction and value callbacks, but those critical
sections only update MMIO-backed GPIO registers and do not contain
sleepable operations. Keeping this register lock non-sleeping is
therefore appropriate for the irqchip callbacks and does not change the
GPIO-side locking contract.

VFIO updates for v7.2-rc1
- Fix out-of-tree vfio selftest builds with make O=. (Jason Gunthorpe)
- Allow vfio selftests to build when ARCH=x86 is used for 64-bit x86
builds. (David Matlack)
- Tighten vfio selftest infrastructure with stricter builds, safer
path handling, sysfs helpers, and reusable device/VF-token setup.
Build on that to add the SR-IOV UAPI selftest across supported
IOMMU modes. (Raghavendra Rao Ananta)
- Conclude earlier vfio PCI BAR work already taken as v7.1 fixes by
replacing vfio_pci_core_setup_barmap() and direct barmap[] access
with vfio_pci_core_get_iomap(). Fix resulting sparse warnings.
(Matt Evans)
- Simplify hisi_acc vfio-pci variant driver device-info reads by
using the mailbox's new direct command-based read helper.
(Weili Qian)
- Avoid duplicate reset handling in the Xe vfio-pci variant driver
reset-done path. (GuoHan Zhao)
- Resolve a lockdep circular dependency splat by tracking active
VFs with a private sriov_active flag rather than calling
pci_num_vf() under memory_lock. (Raghavendra Rao Ananta)
- Add CXL DVSEC-based readiness polling for Blackwell-Next in the
nvgrace-gpu vfio-pci variant driver, including interruptible,
lockless waits to support worst case spec defined timeouts.
(Ankit Agrawal)
- Prevent vfio_mig_get_next_state() from spinning forever on blocked
migration state transition. (Junrui Luo)
- Fix a qat vfio variant driver migration resume race by taking the
migration file lock before boundary checks. (Giovanni Cabiddu)
- Add explicit dependencies between vfio selftest output object files
and output directories to ensure directories are always created.

soc: devicetree updates for 7.2
There are fewer devicetree updates this time that the last few ones, with
five SoC types getting added:
- Qualcomm Dragonwing IPQ9650 is a new wireless networking SoC using
four Cortex-A55 and one Cortex-A78 core, which is a significant
upgrade from older generations
- ZTE zx297520v3 is an older low-end wireless SoC using a single
Cortex-A53 core, which so far can only run 32-bit kernels. This brings
back the ZX family of chips that was removed in 2021 after support
for the original zx296702 and zx296718 chips was never completed.
- Renesas R-Car M3Le (R8A779MD) is a variant of the R-Car M3-N (R8A77965)
automotive SoC.
- Apple t8122 (M3) is the 2023 generation of their laptop SoCs,
which has now been reverse-engineered to the point of having initial
kernel support for five laptop models.
- ASPEED AST27xx is their first baseboard managment controller using
a 64-bit core, the Cortex-A35, following earlier generations using
ARMv5/v6/v7 CPUs.
These all come with one or more initial boards, and in total there
are 39 new boards getting added across SoC families, including:
- Two NAS boxes using the old Cortina Systems Gemini SoC based on
an ARMv4 FA526 CPU core
- 18 industrial embedded boards using NXP i.MX6/8/9 and LX2160A
SoCs from Variscite, Toradex and SolidRun, plus a number of
overlays for combinations with additional boards
- One new carrier board and SoM using TI K3 AM62x, in addition to
new overlays for older SoMs
- Two new boards using Spacemit K3 (no relation with TI) RISC-V
SoCs.
- Three phones from Google, Nothing and Motorola, all using Qualcomm
Snapdragon SoCs
- AST26xx BMC support for two server boards
While there is still a significant number of patches improving hardware
support for the existing boards across vendors (NXP, Qualcomm, Renesas,
Rockchips, Mediatek, ...), a much smaller number of cleanups and warning
fixes have made it in this time.

Merge tag 'soc-dt-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC devicetree updates from Arnd Bergmann:
"There are fewer devicetree updates this time that the last few ones,
with five SoC types getting added:
- Qualcomm Dragonwing IPQ9650 is a new wireless networking SoC using
four Cortex-A55 and one Cortex-A78 core, which is a significant
upgrade from older generations
- ZTE zx297520v3 is an older low-end wireless SoC using a single
Cortex-A53 core, which so far can only run 32-bit kernels. This
brings back the ZX family of chips that was removed in 2021 after
support for the original zx296702 and zx296718 chips was never
completed.
- Renesas R-Car M3Le (R8A779MD) is a variant of the R-Car M3-N
(R8A77965) automotive SoC.
- Apple t8122 (M3) is the 2023 generation of their laptop SoCs, which
has now been reverse-engineered to the point of having initial
kernel support for five laptop models.
- ASPEED AST27xx is their first baseboard managment controller using
a 64-bit core, the Cortex-A35, following earlier generations using
ARMv5/v6/v7 CPUs.
These all come with one or more initial boards, and in total there are
39 new boards getting added across SoC families, including:
- Two NAS boxes using the old Cortina Systems Gemini SoC based on an
ARMv4 FA526 CPU core
- 18 industrial embedded boards using NXP i.MX6/8/9 and LX2160A SoCs
from Variscite, Toradex and SolidRun, plus a number of overlays for
combinations with additional boards
- One new carrier board and SoM using TI K3 AM62x, in addition to new
overlays for older SoMs
- Two new boards using Spacemit K3 (no relation with TI) RISC-V SoCs.
- Three phones from Google, Nothing and Motorola, all using Qualcomm
Snapdragon SoCs
- AST26xx BMC support for two server boards
While there is still a significant number of patches improving
hardware support for the existing boards across vendors (NXP,
Qualcomm, Renesas, Rockchips, Mediatek, ...), a much smaller number
of cleanups and warning fixes have made it in this time"

"A number of SELinux patches, almost all of which are either minor
fixes or hardening patches:
- Additional verifications when loading new SELinux policy
Multiple patches by Christian Göttsche to add additional
validations to the code responsible for loading and parsing SELinux
policy as it is loaded into the kernel.
- Avoid nontransitive comparisons comparisons in our sorting code
Done to prevent unexpected sorting results due to overflow. Qualys
documented a similar issue with glibc
https://www.qualys.com/2024/01/30/qsort.txt
- Consistently use u16 for SELinux security classes
- Move from page allocations to kmalloc() based allocations
Unfortunately one of these patches had to be reverted, but you
should see a fixed version during the next merge window.
- Move from kmalloc_objs() to kzalloc_objs() in the policy load code
- Reorder sel_kill_sb() slightly to match other pseudo filesystems
- Simplify things with QSTR() instead of QSTR_INIT()

sched_ext: Changes for v7.2
This depends on the BPF arena work in bpf-next and should be pulled after
it. for-7.1-fixes was merged in a few times to avoid conflicts with the
feature changes.
- Most of this continues the in-development sub-scheduler support, which
lets a root BPF scheduler delegate to nested sub-schedulers. The
dispatch-path building blocks landed in 7.1. A follow-up patchset in
development will complete enqueue-path support for hierarchical
scheduling. This cycle adds most of that infrastructure:
- Topological CPU IDs (cids): a dense, topology-ordered CPU numbering
where the CPUs of a core, LLC, or NUMA node form contiguous ranges,
so a topology unit becomes a (start, length) slice. Raw CPU numbers
are sparse and don't track topological closeness, which makes them
clumsy for sharding work across sub-schedulers and awkward in BPF.
- cmask: bitmaps windowed over a slice of cid space, so a sub-scheduler
can track, for example, the idle cids of its shard without a full
NR_CPUS cpumask.
- A struct_ops variant that cid-form sub-schedulers register with,
along with the cid-form kfuncs they call.
- BPF arena integration, which sub-scheduler support is built on. The
bpf-next additions let the kernel read and write the BPF scheduler's
arena directly, turning it into a real kernel/BPF shared-memory
channel. Shared state like the per-CPU cmask now lives there.
- scx_qmap is reworked to exercise the new arena and cid interfaces.
- Exit-dump improvements: dump the faulting CPU first, expose the exit
CPU to BPF and userspace, and normalize the dump header.
- Misc kfuncs and cleanups: a task-ID lookup kfunc, __printf checking on
the error and dump formatters, header reorganization, and assorted
fixes.

Modules changes for v7.2-rc1
- Add a missing return value check for module_extend_max_pages() to prevent a kernel oops on memory allocation failure. - Force sh_addr to 0 for architecture-specific module sections on arm, arm64, m68k, and riscv. This prevents non-zero section addresses when linking modules with ld.bfd -r, which may cause tools to misbehave and result in worse compressibility. - Replace pr_warn! with pr_warn_once! for set_param null pointer warnings in Rust abstractions, now that the _once variant is available. Note that as part of our maintainer rotation, Petr Pavlu will be taking over module subsystem pull requests for the next six months.

dt-bindings: mfd: syscon: Revert renesas,r9a08g046-lvds-cmn
Revert commit 51284d8b1dbc ("dt-bindings: mfd: syscon: Document the
LVDS_CMN syscon for the RZ/G3L") because it is completely not matching
reality and clearly incorrect in respect of renesas,r9a08g046-lvds-cmn.
It wasn't ever build-tested by author on their DTS, either.
The documented renesas,r9a08g046-lvds-cmn compatible clearly disallows
any children and simple-mfd fallback, however its only use in original
patchset is with simple-mfd and children, so this could have never
worked.

dt-bindings: mfd: st,stmpe: Add missing properties for PWM subnode
The st,stmpe-pwm binding is already covered by the MFD schema in Documentation/devicetree/bindings/mfd/st,stmpe.yaml. However, the PWM subnode was missing a 'required' properties block. This allowed Device Tree nodes to pass validation even if the 'compatible' string was omitted. This omission could lead to probe failures at runtime. Fix the schema by adding the missing 'required' block.

dt-bindings: mfd: aspeed,ast2x00-scu: Support AST2700 SoC1 pinctrl
The AST2700 SoC integrates two interconnected SoC instances, each managed by its own System Control Unit (SCU). Allow the AST2700 SoC1 pin controller to be described as a child node of the SCU by extending the compatible strings accepted by the SCU binding. There is no functional change to the SCU binding beyond permitting the aspeed,ast2700-soc1-pinctrl compatible string.

mfd: tps6586x: Fix OF node refcount
Platform devices created with platform_device_alloc() call
platform_device_release() when the last reference to the device's
kobject is dropped. This function calls of_node_put() unconditionally.
This works fine for devices created with platform_device_register_full()
but users of the split approach (platform_device_alloc() +
platform_device_add()) must bump the reference of the of_node they
assign manually. Add the missing call to of_node_get().

mfd: twl4030-power: Update checks for specific boards to use the DT
The twl4030-power driver contains two checks for ARM machine IDs via machine_is_*() macros. The two boards concerned now support only FDT booting, which does not use machine IDs, and therefore the code should be updated to check the DT compatible property instead. The legacy board files for these machines were removed in commit |
