3dc7c00116 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.

3dc0df0339 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.

aab799b1bd 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.

 - Fix a recursive deadlock when duplicating executable file rules

   Avoid multiple lookups and attempted I_MUTEX_PARENT locks when moving
   watched files by passing the already resolved inodes through the
   audit code.

 - Fix removal of executable watch rules after the file is deleted

   Prior to this fix we were unable to remove an executable file watch
   where the file had been previously deleted due to a negative dentry
   check in the code that performs the lookup on the file watches.

 - Convert our basic "unsigned" type usage to "unsigned int".

5b33fc6492 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.

056e065a6b sound updates for 7.2-rc1 
Unsurprisingly, we've had a fairly busy development cycle with
 various fixes and enhancements.  While the majority of changes consist
 of device-specific fixes, a significant number of cleanups, hardening,
 and modernizations have been applied to the core frameworks as well.
 
 Below are some highlights:
 
 * ALSA Core:
 - Hardening, race condition, and UAF/leak fixes in the ALSA timer and
   sequencer cores
 - Widespread adoption of flexible array members across core structures
 - Integration of new simple refcount helper functions to simplify code
 
 * ASoC Core:
 - Introduction of a unified SoundWire enumeration helper to clean up
   redundant device initialization across codecs
 - Enhancements to SDCA support, including handling devices with
   multiple functions of the same type and proper jack reporting masks
 - Continued refactoring of ASoC component debugfs and DAPM structures
 - Simplification and improvements to the format auto-selection
   mechanism
 - Added shared BCLK rate constraints for cross-DAI coordination
 
 * ASoC Platforms & Codecs:
 - Initial bring-up and power management support for AMD ACP 7.x
 - Support for Everest Semi ES9356 (SDCA), Mediatek MT2701 (on-chip
   HDMI) and MT8196 SoCs, Renesas RZ/G3E, SpacemiT K3, and TI
   TAC5xx2/TAS67524
 - Added a new generic driver for GPIO-driven amplifiers
 - Continued mass conversion of locking code to guard() helpers across
   numerous platform drivers (MediaTek, Rockchip, STM32, Samsung, etc.)
 - Cleanup of legacy non-DT platform data and rollbacks for obsolete SH
   Ecovec24/7724se boards
 
 * HD- and USB-Audio:
 - Device-specific hardware quirks and fixes for various Realtek
   HD-Audio devices (Lenovo, HP, ASUS, Acer, Clevo)
 - Refinements to Qualcomm USB-audio offloading support
 - Front-panel controls and autogain status support for Scarlett Gen 4
 - Quirks for XIBERIA (K03S), Sennheiser (MOMENTUM 3), Edifier (MF200),
   Novation (Mininova), and Behringer (Flow 8) USB-audio devices
 - Improved robustness by rolling back or propagating write errors to the
   mixer control caches (Babyface Pro, US-16x08, Scarlett)
 
 * Others:
 - Support for the HT-Omega eClaro PCI sound card in the Oxygen driver
 - Robustness improvements and fixes for Virtio-audio, Xen-front, and
   legacy OSS dmasound drivers

Pull bpf updates from Alexei Starovoitov:
 "Major changes:

   - Recover from BPF arena page faults using a scratch page and add
     ptep_try_set() for lockless empty-slot installs on x86 and arm64.

     This allows BPF kfuncs to access arena pointers directly.

     The 'arena_direct_access' stable branch was created for this work
     and was pulled into sched-ext and bpf-next trees (Tejun Heo, Kumar
     Kartikeya Dwivedi)

   - Lift old restriction and support 6+ arguments in BPF programs and
     kfuncs on x86 and arm64 (Yonghong Song, Puranjay Mohan)

  Other features and fixes:

   - Add 24-bit BTF vlen and reclaim unused bits in the BTF UAPI to ease
     addition of new BTF kinds (Alan Maguire)

   - Raise the maximum BPF call chain depth from 8 to 16 frames (Alexei
     Starovoitov)

   - Refactor object relationship tracking in the verifier and fix a
     dynptr use-after-free bug (Amery Hung)

   - Harden the signed program loader and reject exclusive maps as inner
     maps (Daniel Borkmann)

   - Replace the verifier min/max bounds fields with a circular number
     (cnum) representation and improve 32->64 bit range refinements
     (Eduard Zingerman)

   - Introduce the arena library and runtime (libarena) with a buddy
     allocator, rbtree and SPMC queue data structures, ASAN support and
     a parallel test harness. Allow subprograms to return arena pointers
     and switch to a BTF type-tag based __arena annotation (Emil
     Tsalapatis)

   - Cache build IDs in the sleepable stackmap path and avoid faultable
     build ID reads under mm locks (Ihor Solodrai)

   - Introduce the tracing_multi link to attach a single BPF program to
     many kernel functions at once. Allow specifying the uprobe_multi
     target via FD (Jiri Olsa)

   - Extend the bpf_list family of kfuncs with bpf_list_add/del(), and
     bpf_list_is_first/is_last/empty() (Kaitao Cheng)

   - Extend the BPF syscall with common attributes support for
     prog_load, btf_load and map_create (Leon Hwang)

   - Wrap rhashtable as BPF map (Mykyta Yatsenko, Herbert Xu)

   - Add sleepable support for tracepoint programs and fix deadlocks in
     LRU map due to NMI reentry (Mykyta Yatsenko)

   - Fix OOB access in bpf_flow_keys, fix nullness analysis of inner
     arrays, enforce write checks for global subprograms (Nuoqi Gui)

   - Report the maximum combined stack depth and print a breakdown of
     instructions processed per subprogram (Paul Chaignon)

   - Add an XDP load-balancer benchmark and arm64 JIT support for stack
     arguments (Puranjay Mohan)

   - Add kfuncs to traverse over wakeup_sources (Samuel Wu)

   - Allow sleepable BPF programs to use LPM trie maps directly (Vlad
     Poenaru)

   - Many more fixes and cleanups across the verifier, BTF, sockmap,
     devmap, bpffs, security hooks, s390/riscv/loongarch JITs,
     rqspinlock, libbpf, bpftool, selftests"

Linus Torvalds
b85966adbf 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.
    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, soon.
 
  - Remove 5/10 MHz support from cfg80211/mac80211.
 
 Drivers
 -------
 
  - Software:
    - Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit).
    - bonding: add knob to strictly follow 802.3ad for link state.
 
  - New drivers:
    - Alibaba Elastic Ethernet Adaptor (cloud vNIC).
    - NXP NETC switch within i.MX94.
 
  - DPLL:

    - Add generic DPLL type, for daisy-chaining DPLLs (implement in ice).
 
  - Ethernet high-speed NICs:
    - Huawei (hinic3):
      - enhance tc flow offload support with queue selection, tunnels
    - nVidia/Mellanox:
      - avoid over-copying payload to the skb's linear part (up to 60%
        win for LRO on slow CPUs like ARM64 V2)
      - expose more per-queue stats over the standard API
      - support additional, unprivileged PFs in the DPU configuration
      - support Socket Direct (multi-PF) with switchdev offloads
      - add a pool / frag allocator for DMA mapped buffers for control
        objects, save memory on systems with 64kB page size
      - take advantage of the ability to dynamically change RSS table
        size, even when table is configured by the user

     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,
     soon.

   - Remove 5/10 MHz support from cfg80211/mac80211.

406e8a651a net: skmsg: preserve sg.copy across SG transforms 
The sk_msg sg.copy bitmap is part of the scatterlist entry ownership
state. A set bit tells sk_msg_compute_data_pointers() not to expose the
entry through writable BPF ctx->data. This protects entries backed by
pages that are not private to the sk_msg, such as splice-backed file
page-cache pages.

Several sk_msg transform paths move, copy, split, or compact
msg->sg.data[] entries without moving the matching sg.copy bit. This can
make an externally backed entry arrive at a new slot with a clear copy
bit. A later SK_MSG verdict can then expose sg_virt(sge) as writable
ctx->data and BPF stores can modify the original page cache.

Keep sg.copy synchronized with sg.data[] whenever entries are
transferred, shifted, split, or copied into a new sk_msg. Clear the bit
when an entry is replaced by a newly allocated private page or freed.
This covers the BPF pull/push/pop helpers, sk_msg_shift_left/right(),
sk_msg_xfer(), and tls_split_open_record(), including the partial tail
entry created during TLS open-record splitting.

8a398a0c18 appletalk: move the protocol out of tree 
AppleTalk has been removed in MacOS X 10.6 (Snow Leopard), in 2009,
according to Wikipedia. We recently got a burst of AI generated
fixes to this protocol which nobody is reviewing.

Let AppleTalk follow AX.25 and hamradio out of the Linux tree.
We we will maintain the code at: github.com/linux-netdev/mod-orphan
for anyone interested in playing with it.

Retain the uAPI for now. No strong reason, simply because I suspect
keeping it will be less controversial.

023f9b0f2f appletalk: stop storing per-interface state in struct net_device 
AppleTalk keeps its per-interface control block (struct atalk_iface)
directly in struct netdevice (dev->atalk_ptr). This is the only thing
tying the protocol into the core net_device layout and is the sole
blocker to moving AppleTalk out of tree.

Replace dev->atalk_ptr with a small ifindex-keyed hashtable internal
to ddp.c. The existing atalk_interfaces list stays the owner of the iface
objects; the hashtable is purely a fast dev->iface index and reuses
the same atalk_interfaces_lock.

AFAICT this patch does not make this code any more racy than it already
is, I'm sure Sashiko will point out some basically existing bugs.
AFAICT atalk_interfaces_lock is the innermost lock already.

79511603a6 tls: remove dead sockmap (psock) handling from the SW path 
TLS and sockmap are now mutually exclusive. Try to delete the code
from sendmsg and recvmsg path which is now obviously dead.

The main goal is to delete enough code for AI security scanners
to no longer bother us with sockmap related bugs. At the same
time retain the code in case someone has the cycles to fix
all of this and make the integration work, again.

If the integration does not get restored we can wipe the rest
of the skmsg code from TLS in two or three releases.

The changes on the Tx side are deeper since that's where most
of the bugs are, Rx side simply takes the data from sockmap
and gives it to the user. On Tx split record handling and
rolling back the iterator were the two problem areas.

8f9616500c atm: remove orphaned uAPI for deleted drivers, protocols and SVCs 
ATM removals have left a number of uAPI headers and ioctl
definitions with no in-kernel implementation behind them:

 - device headers for adapters deleted with the legacy PCI/SBUS drivers:
   atm_eni.h, atm_he.h, atm_idt77105.h, atm_nicstar.h, atm_zatm.h and
   the atmtcp pair atm_tcp.h / <linux/atm_tcp.h>
 - protocol headers for the removed CLIP, LANE and MPOA stacks:
   atmarp.h, atmclip.h, atmlec.h, atmmpc.h
 - atmsvc.h and the SVC / p2mp / local-address ioctls in atmdev.h
   (ATM_{GET,RST,ADD,DEL}ADDR, ATM_{ADD,DEL,GET}LECSADDR,
   ATM_{ADD,DROP}PARTY) left behind by the SVC and address-registry
   removals

None of these are referenced by any remaining in-tree code.
Let's try to delete all this. Chances are nobody cares about
these headers any more. I'm keeping this separate from the
kernel side code changes for ease of revert, in case I am
proven wrong...

e44e224e2f atm: remove unused ATM PHY operations 
The PHY operations are vestiges of the SAR/framer split used by the
removed PCI/SBUS ATM adapters:

 - atmdev_ops::phy_put / ::phy_get (register accessors) are never called
   by the core and solos-pci only listed them as NULL
 - struct atmphy_ops and atm_dev::phy have no users at all - nothing
   assigns or dereferences them

Remove all of them. atm_dev::phy_data is kept: solos-pci repurposes it
to stash its per-port channel index.

no remaining ATM driver sets either, so vcc_sendmsg() always skipped
pre_send and the raw AAL0/AAL5 paths always fell back to ->send().

atmdev_ops::change_qos() was the hook for renegotiating the traffic
parameters of an already-connected VCC, driven from SO_ATMQOS on a

None of the ATM drivers left in tree implement it - solos-pci only listed
change_qos = NULL - so atm_change_qos() always returned -EOPNOTSUPP.

aa582dc25a atm: remove SVC socket support and the signaling daemon interface 
ATM switched virtual circuits (SVCs) are set up and torn down by a
user-space signaling daemon (atmsigd) which the kernel talks to over
a dedicated "sigd" socket: the kernel marshals Q.2931-style requests
(as_connect, as_listen, as_accept, as_close, ...) to the daemon and
applies the results to PF_ATMSVC sockets. This is the machinery behind
classical SVC use and was the foundation for LANE / MPOA, all of which
have been removed.

DSL deployments do not use any of this. PPPoATM and BR2684 run over
permanent virtual circuits (PF_ATMPVC) with a statically configured
VPI/VCI; no atmsigd, no Q.2931. Neither remaining ATM driver
(solos-pci, the USB DSL modems) is reachable through the SVC path.

Remove the SVC socket family and the signaling interface:

 - delete net/atm/svc.c, net/atm/signaling.c and signaling.h
 - drop atmsvc_init()/atmsvc_exit() and the PF_ATMSVC registration and
   module alias
 - drop the ATMSIGD_CTRL ioctl (sigd_attach) and the /proc/net/atm/svc
   file
 - fold the SVC branch out of atm_change_qos(); all sockets are PVCs now

The obsolete ATM_SETSC ioctl stub is left in place (it already just
warns and returns 0), as is the struct atm_vcc SVC bookkeeping shared
with the queueing layer.

a5a12d76d2 atm: remove the local ATM (NSAP) address registry 
net/atm/addr.c maintained the per-device lists of local NSAP addresses
(dev->local) and ILMI-learned LECS addresses (dev->lecs). These exist
solely to serve SVC signaling: the lists are populated through the
ATM_{ADD,DEL,RST}ADDR / ATM_{ADD,DEL,GET}LECSADDR ioctls used by the
atmsigd / ILMI daemons, and consumed when registering addresses with the
signaling daemon. The LECS list belonged to LAN Emulation, which has
been removed.

With no SVC users in a DSL-only configuration these lists are always
empty, so drop the registry entirely:

 - remove the ADDR/LECSADDR/RSTADDR ioctls
 - drop the now-always-empty "atmaddress" sysfs attribute
 - remove the dev->local / dev->lecs lists, structs and enums
 - delete net/atm/addr.c and net/atm/addr.h

The device ESI ("MAC" address) and its ATM_{G,S}ETESI ioctls and
"address" sysfs attribute are retained - the USB DSL modems populate
the ESI.

The atmdev_ops::send_oam device operation and the atm_vcc::push_oam
callback were the kernel's interface for raw F4/F5 OAM cell exchange.
Nothing assigns them a non-NULL value and nothing ever invokes them:
the core only ever initialises push_oam to NULL (in vcc_create() and the
AAL init helpers) and the Solos driver only lists send_oam = NULL for
documentation. The drivers that actually drove OAM through these hooks
were removed along with the legacy ATM adapters.

Drop both callbacks and the NULL initialisers.

Pull io_uring updates from Jens Axboe:

 - Rework the task_work infrastructure.

   Both the local (DEFER_TASKRUN) and the normal (tctx) task_work lists
   were llist based, which is LIFO ordered, and hence each run had to do
   an O(n) list reversal pass first to restore queue order.
   Additionally, to cap the amount of task_work run, each method needed
   a retry list as well.

   Add a lockless MPCS FIFO queue (based on Dmitry Vyukov's intrusive
   MPSC algorithm) and switch both task_work lists to it. It performs
   better than llists and we can then also ditch the retry lists as well
   as entries are popped one-at-the-time.

   On top of those changes, run the tctx fallback task_work directly and
   remove the now-unused per-ctx fallback machinery entirely.

 - zcrx user notifications.

   Add a mechanism for zcrx to communicate conditions back to userspace
   via a dedicated CQE, with the initial users being notification on
   running out of buffers and on a frag copy fallback, plus
   shared-memory notification statistics.

   Alongside that, a series of zcrx reliability and cleanup fixes: more
   reliable scrubbing, poisoning pointers on unregistration, dropping an
   extra ifq close, adding a ctx back-pointer, reordering fd allocation
   in the export path, and killing a dead 'sock' member.

 - Allow using io_uring registered buffers for plain SEND and RECV, not
   just for the zero-copy send path.

   This enables targets like ublk's NBD backend to push/pull IO data
   directly to/from a registered buffer over a plain send/recv on a TCP
   socket.

 - Registered buffer improvements: account huge pages correctly, bump
   the io_mapped_ubuf length field to size_t, and raise the previous 1GB
   registered buffer size limit.

 - Restrict the ctx access exposed to io_uring BPF struct_ops programs
   by handing them an opaque type rather than the full io_ring_ctx, and
   add a separate MAINTAINERS entry for the bpf-ops code.

 - Allow opcode filtering on IORING_OP_CONNECT.

 - Validate ring-provided buffer addresses with access_ok(), and align
   the legacy buffer add limit with MAX_BIDS_PER_BGID.

 - Various other cleanups and minor fixes, including avoiding msghdr
   async data on connect/bind, dropping async_size for OP_LISTEN, making
   the POLL_FIRST receive side checks consistent, re-checking
   IO_WQ_BIT_EXIT for each linked work item, and using
   trace_call__##name() at guarded tracepoint call sites.

 "Several fixes in HFS/HFS+ of syzbot reported issues and HFS//HFS+
  fixes of xfstests failures.

   - fix a null-ptr-deref issue reported by syzbot (Edward Adam Davis)

     If the attributes file is not loaded during system mount
     hfsplus_create_attributes_file can dereference a NULL pointer.

     Also, add a b-tree node size check in hfs_btree_open() with the
     goal to prevent an uninit-value bug reported by syzbot for the case
     of corrupted HFS+ image.

   - fix __hfs_bnode_create() by using kzalloc_flex() instead of
     kzalloc() (Rosen Penev)

   - fix early return in hfs_bnode_read() (Tristan Madani)

     hfs_bnode_read() can return early without writing to the output
     buffer when is_bnode_offset_valid() fails or when
     check_and_correct_requested_ length() corrects the length to zero.
     Callers such as hfs_bnode_read_ u16() and hfs_bnode_read_u8() pass
     stack-allocated buffers and use the result unconditionally, leading
     to KMSAN uninit-value reports.

Pull btrfs updates from David Sterba:
 "The most noticeable change is to enable large folios by default, it's
  been in testing for a few releases. Related to that is huge folio
  support (still under experimental config). Otherwise a few ioctl
  updates, performance improvements and usual fixes and core changes.

  User visible changes:

   - enable large folios by default, added in 6.17 (under experimental
     build), no feature limitations, a big change internally

   - new ioctl to return raw checksums to userspace (a bit tricky given
     compression and tail extents), can be used for mkfs and
     deduplication optimizations

   - provide stable UUID for e.g. overlayfs and temp_fsid, also
     reflected in statvfs() field f_fsid, internal dev_t is hashed in to
     allow cloning

   - add 32bit compat version of GET_SUBVOL_INFO ioctl

   - in experimental build, support huge folios (up to 2M)

  Performance related improvements/changes:

   - limit bio size to the estimated optimum derived from the queue,
     this prevents build up of too much data for writeback, which could
     cause latency spikes (reported improvement 15% on sequential
     writes)

   - don't force direct IO to be serialized, forgotten change during
     mount API port, brings back +60% of throughput

   - lockless calculation of number of shrinkable extent maps, improve
     performance with many memcg allocated objects

  Notable fixes:

   - in zoned mode, fix a deadlock due to zone reclaim and relocation
     when space needs to be flushed

   - don't trim device which is internally not tracked as writeable
     (e.g. when missing device is being rescanned)

   - fix deadlock when cloning inline extent and mounted with
     flushoncommit

   - fix false IO failures after direct IO falls back to buffered write
     in some cases

  Core:

   - remove COW fixup mechanism completely; detect and fix changes to
     pages outside of filesystem tracking, guaranteed since 5.8, grace
     period is over

   - remove 2K block size support, experimental to test subpage code on
     x86_64 but now it would block folio changes

   - tree-checker improvements of:
      - free-space cache and tree items
      - root reference and backref items
      - extent state exceptions in reloc tree

   - subpage mode updates:
      - code optimizations, simplify tracking bitmaps
      - re-enable readahead of compressed extent
      - extend bitmap size to cover huge folios

   - add tracepoints related to sync, tree-log and transactions

   - device stats item tracking unification, remove item if there are no
     stats recorded, also don't leave stale stats on replaced device

   - allow extent buffer pages to be allocated as movable, to help page
     migration

   - added checks for proper extent buffer release

   - btrfs.ko code size reduction due to transaction abort call
     simplifications

   - several struct size reductions

   - more auto free conversions

   - more verbose assertions"

Pull slab updates from Vlastimil Babka:

 - Support for "allocation tokens" (currently available in Clang 22+)
   for smarter partitioning of kmalloc caches based on the allocated
   object type, which can be enabled instead of the "random"
   per-caller-address-hash partitioning.

   It should be able to deterministically separate types containing a
   pointer from those that do not (Marco Elver)

 - Improvements and simplification of the kmem_cache_alloc_bulk() and
   mempool_alloc_bulk() API. This includes adaptation of callers
   (Christoph Hellwig)

 - Performance improvements and cleanups related mostly to sheaves
   refill (Hao Li, Shengming Hu, Vlastimil Babka)

 - Several fixups for the slabinfo tool (Xuewen Wang)

c41cfae42c spi: Updates for v7.2 
This has been quite a busy release, mainly due to the subsystem wide
 work Johan Hovold has done to modernise resource allocation for the
 subsystem on probe, the subsystem did some very clever allocation
 management pre devm which didn't quite mesh comfortably with managed
 allocations and made it far too easy to introduce error handling and
 removal bugs.
 
  - Cleanup and simplification of controller struct allocation, moving
    everything over to devm and making the devm APIs more robust, from
    Johan Hovold
  - Support for spi-mem devices that don't assert chip select and support
    for a secondary read command for memory mapped flashes, some commits
    for this are shared with mtd.
  - Support for SpacemiT K1.
 
 There will be a simple add/add conflict with the i2c-host tree in the
 x86 quirk data in drivers/acpi/acpi_apd.c.

Pull power sequencing updates from Bartosz Golaszewski:
 "A set of extensions to the M.2 pwrseq driver allowing it to work with
  more cards than just the one from Qualcomm we supported initially.
  There's also a tweak to debugfs output and a new function that will be
  used by a bluetooth driver in the next cycle.

  Power Sequencing core:

   - Add a helper allowing consumers to access the struct device object
     associated with a pwrseq provider

   - Print the power sequencing device's parent in debugfs to add more
     debugging information

  Driver updates:

   - Extend/rework the M.2 power sequencing driver in order to allow it
     to support more M.2 cards, not just WCN7850"
