Docs/driver-api/uio-howto: document mmap_prepare callback
The UIO howto still documents an mmap callback in struct uio_info.
That field was replaced by mmap_prepare, which takes a struct
vm_area_desc.
A UIO driver following the current howto no longer builds because
struct uio_info has no mmap member. Update the documented callback
signature and matching text to match the current API.
Fixes:

NAND changes:
- Extend SPI NAND continuous read to Winbond devices, which requires
numerous changes in the spi-{mem,nand} layers such as the need for a
secondary read operation template.
- Continuous reads in general have also been enhanced/fixed for avoiding
potential issues at probe time and at block boundaries.
SPI NOR changes:
- Big set of cleanups and improvements to the locking support. This
series contains some cleanups and bug fixes for code and documentation
around write protection. Then support is added for complement locking,
which allows finer grained configuration of what is considered locked
and unlocked. Then complement locking is enabled on a bunch of Winbond
W25 flashes.
- Fix die erase support on Spansion flashes. Die erase is only supported
on multi-die flashes, but the die erase opcode was set for all. When
the opcode is set, it overrides the default chip erase opcode which
should be used for single-die flashes. Only set the opcode on
multi-die flashes. Also, the opcode was not set on multi-die s28hx-t
flashes. Set it so they can use die-erase correctly.
General changes:
- A few drivers and mappings have been removed following SoCs support
removal.
- And again, there is the usual load of misc improvements and fixes.

Networking changes for 7.2.
Core & protocols
----------------
- Work on removing rtnl_lock protection throughout the stack continues.
In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even tho
user space wants a dump of all netdevs, most of the time, the OOO
programming model results in repeating the dump for each netdev.
Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on retransmit
timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 > 40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot express
reqid changes or migrate Transport mode selectors. The new interface
identifies the SA via SPI and mark, supports reqid changes, address
family changes, encap removal, and uses an atomic create+install
flow under x->lock to prevent SN/IV reuse during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff
----------------
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto API
users, since it changed crypto transformation objects into reference-
-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the global
crypto API as obsolete and insecure.
Wireless
--------
- Major rework of station bandwidth handling, fixing issues with lower
capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter
---------
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions
---------
- Remove TLS + sockmap integration. TLS wants to pin user pages
to avoid a copy, and sockmap wants to write to the input stream.

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Work on removing rtnl_lock protection throughout the stack
continues. In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even
tho user space wants a dump of all netdevs, most of the time, the
OOO programming model results in repeating the dump for each
netdev. Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on
retransmit timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 >
40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot
express reqid changes or migrate Transport mode selectors.
The new interface identifies the SA via SPI and mark, supports
reqid changes, address family changes, encap removal, and uses an
atomic create+install flow under x->lock to prevent SN/IV reuse
during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff:
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto
API users, since it changed crypto transformation objects into
reference-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the
global crypto API as obsolete and insecure.
Wireless:
- Major rework of station bandwidth handling, fixing issues with
lower capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter:
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions:
- Remove TLS + sockmap integration. TLS wants to pin user pages to
avoid a copy, and sockmap wants to write to the input stream. More
work on this integration is clearly needed, and we can't find any
users (original author admitted that they never deployed it).
- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from the
vendor that added this are AWOL.
- Remove more ATM code, trying to leave behind only what PPPoATM
needs, AAL5 and br2684 with permanent circuits.
- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.
- Disable 32-bit x_tables compatibility (32bit binaries on 64bit
kernel) interface in user namespaces. To be deleted completely,

driver core: platform: set mod_name in driver registration
Pass KBUILD_MODNAME through the driver registration macro so that the
driver core can create the module symlink in sysfs for built-in drivers,
and fixup all callers.
The Rust platform adapter is updated to pass the module name through to
the new parameter.
Tested on qemu with:
- x86 defconfig + CONFIG_RUST
- arm64 defconfig + CONFIG_RUST + CONFIG_CORESIGHT stuff
Examples after this patch:
/sys/bus/platform/drivers/...
coresight-itnoc/module -> coresight_tnoc
coresight-static-tpdm/module -> coresight_tpdm
coresight-catu-platform/module -> coresight_catu

nvdimm/btt: Handle preemption in BTT lane acquisition
BTT lanes serialize access to per-lane metadata and workspace state
during BTT I/O. The btt-check unit test reports data mismatches during
BTT writes due to a race in lane acquisition that can lead to silent
data corruption.
The existing lane model uses a spinlock together with a per-CPU
recursion count. That recursion model stopped being valid after BTT
lanes became preemptible: another task can run on the same CPU,
observe a non-zero recursion count, bypass locking, and use the same
lane concurrently.
BTT lanes are also held across arena_write_bytes() calls. That path
reaches nsio_rw_bytes(), which flushes writes with nvdimm_flush().
Some provider flush callbacks can sleep, making a spinlock the wrong
primitive for the lane lifetime.
Replace the spinlock-based recursion model with a dynamically
allocated per-lane mutex array and take the lane lock
unconditionally.
Add might_sleep() to catch any future atomic-context caller.
Found with the ndctl unit test btt-check.sh.

dpll: add fractional frequency offset to pin-parent-device
Add both fractional-frequency-offset (PPM) and fractional-frequency-offset-ppt (PPT) attributes to the pin-parent-device nested attribute set, alongside the existing top-level pin attributes. Both carry the same measurement at different precisions. Introduce enum dpll_ffo_type and struct dpll_ffo_param to distinguish FFO contexts: DPLL_FFO_PORT_RXTX_RATE for the RX vs TX symbol rate offset reported at the top level, and DPLL_FFO_PIN_DEVICE for the pin vs parent DPLL offset reported in the pin-parent-device nest. Add a supported_ffo bitmask to struct dpll_pin_ops so drivers declare which FFO types they support. The core only calls ffo_get for types the driver has opted into, eliminating the need for per-driver NULL pointer guards. Validate at pin registration time that supported_ffo is not set without an ffo_get callback. Update mlx5 (DPLL_FFO_PORT_RXTX_RATE) and zl3073x (DPLL_FFO_PORT_RXTX_RATE) drivers to use the new API. Add documentation for both FFO types to dpll.rst. Changes v3 -> v4: - Replace dpll=NULL overloading with enum dpll_ffo_type and struct dpll_ffo_param (Jakub Kicinski) - Add supported_ffo opt-in bitmask in dpll_pin_ops for fail-close driver validation (Jakub Kicinski) - Add WARN_ON in dpll_pin_register for supported_ffo without ffo_get callback Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Ivan Vecera <ivecera@redhat.com> Link: https://patch.msgid.link/20260511155816.99936-2-ivecera@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

Defined operational states: - active: pin is qualified and actively used by the DPLL - standby: pin is qualified but not actively used by the DPLL - no-signal: pin does not have a valid signal - qual-failed: pin signal failed qualification The operstate is reported inside the pin-parent-device nested attribute alongside the existing state and phase-offset attributes.

iio: ABI: Add support for floating-point numbers in buffer scan elements
In the data storage description of a scan element, the first character after the colon can have the values 's' and 'u' to specify signed and unsigned integers, respectively. Add 'f' as an allowed value to specify floating-point numbers formatted according to the IEEE 754 standard.

iio: Replace 'sign' field with union in struct iio_scan_type
This field is used to differentiate between signed and unsigned integers. A following commit will extend its use in order to add support for non- integer scan elements; therefore, replace it with a union that contains a more generic 'format' field. This union will be dropped when all drivers are changed to use the format field. Opportunistically replace character literals with symbolic constants that represent the set of allowed values for the format field.

We've finally gotten rid of the struct clk_ops::round_rate() code after months
of effort from Brian Masney. Now the only option is to use determine_rate(),
which is good because that takes a struct argument instead of just a couple
unsigned longs, allowing us to easily modify the way we determine and set rates
in the clk tree.
Beyond that core framework change we've got the typical pile of new SoC clk
driver additions, fixes for clk data and/or adding missing clks because the
consumer driver using those clks wasn't ready, etc. The usual suspects are all
here: Qualcomm, Samsung, Mediatek, and Rockchip along with some newcomers
making RISC-V SoCs like ESWIN's eic700 and Tenstorrent's Atlantis. The clk
driver side of this looks pretty normal.
Core:
- Remove the round_rate() clk op (yay!)
New Drivers:
- ESWIN eic700 SoC clk support
- Econet EN751221 SoC clock/reset support
- Global TCSR, RPMh, and display clock controller support for
the Qualcomm Eliza platform
- TCSR, the multiple global, and the RPMh clock controller
support for the Qualcomm Nord platform
- GPU clock controller support for Qualcomm SM8750
- Video and GPU clock controller support for Qualcomm Glymur
- Global clock controller support for Qualcomm IPQ5210
- Axis ARTPEC-9: Add new PLL clocks and new drivers for eight clock
controllers on the SoC
- ExynosAutov920: Add G3D (GPU) clock controller
- Clock driver for the Rockchip RV1103B SoC
- Initial support for the Renesas RZ/G3L (R9A08G046) SoC
- Clock and reset controllers (e.g. PRCM) in the Tenstorrent Atlantis SoC

Networking changes for 7.1.
Core & protocols
----------------
- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP.
- Number of code moves to help the compiler with inlining.
Avoid output arguments for returning drop reason where possible.
- Rework drop handling within qdiscs to include more metadata
about the reason and dropping qdisc in the tracepoints.
- Remove the rtnl_lock use from IP Multicast Routing.
- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two.
- Report TCP delayed ack timer information via socket diag.
- Add ip_local_port_step_width sysctl to allow distributing the randomly
selected ports more evenly throughout the allowed space.
- Add support for per-route tunsrc in IPv6 segment routing.
- Start work of switching sockopt handling to iov_iter.
- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up.
- Support MSG_EOR in MPTCP.
- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage.
- Remove UDP-Lite support (as announced in 2023).
- Remove support for building IPv6 as a module.
Remove the now unnecessary function calling indirection.
Cross-tree stuff
----------------
- Move Michael MIC code from generic crypto into wireless,
it's considered insecure but some WiFi networks still need it.
Netfilter
---------
- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.
Florian W reports this gets us ~13% higher packet rate.
- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex.
- Add more opinionated input validation to lower security exposure.
- Make IPVS hash tables to be per-netns and resizable.
Wireless
--------
- Finished assoc frame encryption/EPPKE/802.1X-over-auth.
- Radar detection improvements.
- Add 6 GHz incumbent signal detection APIs.
- Multi-link support for FILS, probe response templates and
client probing.
- New APIs and mac80211 support for NAN (Neighbor Aware Networking,
aka Wi-Fi Aware) so less work must be in firmware.
Driver API
----------
- Add numerical ID for devlink instances (to avoid having to create
fake bus/device pairs just to have an ID). Support shared devlink
instances which span multiple PFs.
- Add standard counters for reporting pause storm events
(implement in mlx5 and fbnic).
- Add configuration API for completion writeback buffering
(implement in mana).
- Support driver-initiated change of RSS context sizes.
- Support DPLL monitoring input frequency (implement in zl3073x).
- Support per-port resources in devlink (implement in mlx5).
Misc
----
- Expand the YAML spec for Netfilter.

A busier cycle than I had expected for docs, including:
- Translations: some overdue updates to the Japanese translations, Chinese
translations for some of the Rust documentation, and the beginnings of a
Portuguese translation.
- New documents covering CPU isolation, managed interrupts, debugging
Python gbb scripts, and more.
- More tooling work from Mauro, reducing docs-build warnings, adding self

replace (some of) the mess of kernel-doc regexes, and more.
- Update and synchronize changes.rst and scripts/ver_linux, and put both

gpio updates for v7.1-rc1
GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI
modules into GPIO core and allow setting up hogs with software nodes
- allow matching GPIO controllers by secondary firmware node if matching
by primary does not succeed
- demote deferral warnings to debug level as they are quite normal when
using software nodes which don't support fw_devlink yet
- disable the legacy GPIO character device uAPI v1 supprt in Kconfig by
default
- rework several core functions in preparation for the upcoming Revocable
helper library for protecting resources against sudden removal, this
reduces the number of SRCU dereferences in GPIO core
- simplify file descriptor logic in GPIO character device code by using
FD_PREPARE()

GPIO drivers by normalizing any values other than 0, 1 or negative error
numbers

Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for
controlling pins.
Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.

Documentation: gpio: update the preferred method for using software node lookup
In its current version, the manual for converting of board files from using GPIO lookup tables to software nodes recommends leaving the software nodes representing GPIO controllers as "free-floating", not attached objects and relying on the matching of their names against the GPIO controller's name. This is an abuse of the software node API and makes it impossible to create fw_devlinks between GPIO suppliers and consumers in this case. We want to remove this behavior from GPIOLIB and to this end, work on converting all existing drivers to using "attached" software nodes. Except for a few corner-cases where board files define consumers depending on GPIO controllers described in firmware - where we need to reference a real firmware node from a software node - which requires a more complex approach, most board files can easily be converted to using propert firmware node lookup. Update the documentation to recommend attaching the GPIO chip's software nodes to the actual platform devices and show how to do it.

staging: vme_user: replace deprecated mmap hook with mmap_prepare
The f_op->mmap interface is deprecated, so update driver to use its successor, mmap_prepare. The driver previously used vm_iomap_memory(), so this change replaces it with its mmap_prepare equivalent, mmap_action_simple_ioremap(). Functions that wrap mmap() are also converted to wrap mmap_prepare() instead. Also update the documentation accordingly.

dpll: add frequency monitoring to netlink spec
Add DPLL_A_FREQUENCY_MONITOR device attribute to allow control over the frequency monitor feature. The attribute uses the existing dpll_feature_state enum (enable/disable) and is present in both device-get reply and device-set request. Add DPLL_A_PIN_MEASURED_FREQUENCY pin attribute to expose the measured input frequency in millihertz (mHz). The attribute is present in the pin-get reply. Add DPLL_PIN_MEASURED_FREQUENCY_DIVIDER constant to allow userspace to extract integer and fractional parts.

docs: interconnect: Add provider APIs to documentation
The "Interconnect providers" section currently only includes data structures from include/linux/interconnect-provider.h. Include drivers/interconnect/core.c to extract provider-specific API documentation. The :functions: directive is used to prevent mixing with consumer APIs.

workqueue: devres: Add device-managed allocate workqueue
Add a Resource-managed version of alloc_workqueue() to fix common problem of drivers mixing devm() calls with destroy_workqueue. Such naive and discouraged driver approach leads to difficult to debug bugs when the driver: 1. Allocates workqueue in standard way and destroys it in driver remove() callback, 2. Sets work struct with devm_work_autocancel(), 3. Registers interrupt handler with devm_request_threaded_irq(). Which leads to following unbind/removal path: 1. destroy_workqueue() via driver remove(), Any interrupt coming now would still execute the interrupt handler, which queues work on destroyed workqueue. 2. devm_irq_release(), 3. devm_work_drop() -> cancel_work_sync() on destroyed workqueue. devm_alloc_workqueue() has two benefits: 1. Solves above problem of mix-and-match devres and non-devres code in driver, 2. Simplify any sane drivers which were correctly using alloc_workqueue() + devm_add_action_or_reset().

reset: convert the core API to using firmware nodes
In order to simplify the commit converting the internals of reset core to using firmware nodes, first convert the user-facing API. Modify the signature of the core consumer functions but leave the specialized wrappers as is to avoid modifying users for now. No functional change intended.

gpio: Document line value semantics
It is not clearly documented that the GPIO driver API expect the driver to get/set the physical level of the GPIO line and the consumer API will get/set the logic level.
