strncpy() has been a persistent source of bugs due to its ambiguous
intended usage and frequently counter-intuitive semantics: it may not
NUL-terminate the destination, and it unconditionally zero-pads to the
full length, which isn't always needed. All former callers have been
migrated[1] to:
- strscpy() for NUL-terminated destinations
- strscpy_pad() for NUL-terminated destinations needing zero-padding
- strtomem_pad() for non-NUL-terminated fixed-width fields
- memcpy_and_pad() for bounded copies with explicit padding
- memcpy() for known-length copies
Remove the generic implementation, its declaration, the FORTIFY_SOURCE
wrapper, and associated tests.

Remove the reference to the obsolete kselftest wiki.
The kselftest wiki is marked obsolete and is no longer updated. The last
edit was in 2019, and the information is outdated, referring readers for
support to IRC networks that have not been used for years, and to kernel
versions that are no longer supported.
If there is any relevant information left in the wiki it needs to be
cleaned up and moved into the canonical kselftest documentation here.

When reading .config input, Kconfig stores user-provided values first
and then resolves the final value after applying dependencies, ranges,
and other constraints.
If the final value differs from the user input, Kconfig already tracks
that state internally, but it does not provide a focused diagnostic to
show which explicit inputs were adjusted. This is particularly confusing
for requested values that get forced down by unmet dependencies or
clamped by ranges.
Add an opt-in diagnostic controlled by KCONFIG_WARN_CHANGED_INPUT. Emit
the warnings from conf_write() and conf_write_defconfig() after value
resolution. Print the diagnostic to stderr directly, not through the
normal message callback, so it remains visible when conf is run with -s,
such as from make -s.
Keep the diagnostic out of the conf_message() formatting buffer so long
warning lists are not truncated, and mark processed symbols as written
before the SYMBOL_WRITE check so duplicate menu nodes cannot emit
duplicate warnings.
Document the new environment variable and add tests for olddefconfig,
savedefconfig, and the silent-conf path.

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. 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"

Pull rdma updates from Jason Gunthorpe:
"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

When the backlight is managed by the panel controller IC, an external
power rail might be powering the backlight.
Add an optional `bl-supply` property to describe such power rail, thus
allow disabling the backlight.

The Chipone ICNA3512 and ICNA3520 DDICs are high refresh, low power
MIPI-DSI drivers for OLED panels. The icna3512 is used by the Ayn Odin 2
Portal and the Ayaneo Pocket DS top panel while the icna3520 is used by
the Ayn Thor top panel and the Ayn Odin 3.
These ddic's are generally compatible, but some MIPI vendor commands
differ between them, so they are not fully fallback compatible.

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"

git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext updates from Tejun Heo:
"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.
Additionally:
- 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"

to per-css so that path is covered too.

usage and rdma.events / rdma.events.local for resource-limit
exhaustion. The max-limit parser was rewritten, fixing two input
parsing bugs.

On DG2 the driver always shows two fan channels, because the
FSC_READ_NUM_FANS command does not work on some cards. OEMs decide how
the fans map to tach channels, so two fans can share one tach line.
When that happens, the second channel reads 0 RPM even though the fan
is spinning.
Note this on the fan2_input ABI entry so the steady 0 RPM is not
mistaken for a driver bug.

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

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.

AST2700 consists of two interconnected SoC instances, each with its own
System Control Unit (SCU). The SCU0 provides pin control, interrupt
controllers, clocks, resets, and address-space mappings for the
Secondary and Tertiary Service Processors (SSP and TSP).
Describe the SSP/TSP address mappings using the standard
memory-region and memory-region-names properties.
Disallow legacy child nodes that are not present on AST2700, including
p2a-control and smp-memram. The latter is unnecessary as software can
access the scratch registers via the SCU syscon.
Also allow the AST2700 SoC0 pin controller to be described as a child
node of the SCU0, and add an example illustrating the SCU0 layout,
including reserved-memory, interrupt controllers, and pinctrl.

Some multicolor LEDs support global brightness control in hardware,
meaning that the maximum intensity of the color components is not
connected to the maximum global brightness. Such LEDs cannot be
described properly by the current multicolor LED class interface,
because it assumes that the maximum intensity of each color component
is described by the maximum global brightness of the LED.
Fix this by introducing a new sysfs attribute called
"multi_max_intensity" holding the maximum intensity values for the
color components of a multicolor LED class device. Drivers can use
the new max_intensity field inside struct mc_subled to tell the
multicolor LED class code about those values. Intensity values written
by userspace applications will be limited to this maximum value.
Drivers for multicolor LEDs that do not support global brightness
control in hardware might still want to use the maximum global LED
brightness supplied via devicetree as the maximum intensity of each
individual color component. Such drivers should set max_intensity
to 0 so that the multicolor LED core can act accordingly.
The lp50xx and ncp5623 LED drivers already use hardware-based control
for the global LED brightness. Modify those drivers to correctly
initalize .max_intensity to avoid being limited to the maximum global
brightness supplied via devicetree.

Document the existing practice of always using 'kbd_backlight' for
the function part of LED class device names for LED class devices which
control single-zone keyboard backlights.
Also extend this existing practice with a new naming scheme for keyboards
with zoned backlight control. There are several drivers in the works (see
the Link:tags below) which offer backlight control for keyboards where
the keyboard backlight is divided in a limited number of zones, e.g.
"main", "cursor" and "numpad" zones.
It is important to agree on a consistent naming scheme for these now,
so that userspace can support multiple different models / vendors through
a single unified naming scheme.
