smb/client: fix chown/chgrp with SMB3 POSIX Extensions
Ownership (chown) and group (chgrp) modifications were being ignored when mounting with SMB3 POSIX Extensions unless CIFS_MOUNT_CIFS_ACL or CIFS_MOUNT_MODE_FROM_SID were also explicitly set. Fix this by checking for posix_extensions in cifs_setattr_nounix() when updating UID and GID, ensuring that id_mode_to_cifs_acl() is called to map and set the ownership/group information on the server.

smb/client: fix security flag calculation when setting security descriptors
In id_mode_to_cifs_acl(), aclflag was initialized to CIFS_ACL_DACL by default. This forced the client to request setting the DACL even when only an ownership (chown) or group (chgrp) change was being performed. Let build_sec_desc() do the proper flag calculation by initializing aclflag to 0. build_sec_desc() sets the appropriate bits (CIFS_ACL_OWNER, CIFS_ACL_GROUP, or CIFS_ACL_DACL) depending on what actually changed. During ownership transfer, CIFS_ACL_DACL is only set if replace_sids_and_copy_aces() actually replaces the SIDs inside any of the DACL's ACEs. If build_sec_desc() results in aclflag being 0 (meaning no changes were mapped), exit early to avoid sending an empty security descriptor update to the server.

smb: client: refactor ACL setting control flow in id_mode_to_cifs_acl()
Refactor the control flow in id_mode_to_cifs_acl() to reduce nesting and prevent error code overwriting. Instead of wrapping the call to ops->set_acl() in a conditional block, introduce early exits (goto id_mode_to_cifs_acl_exit) when build_sec_desc() fails or ops->set_acl is NULL. This ensures that any actual error returned by build_sec_desc() is not overwritten with -EOPNOTSUPP.

smb: client: fix query directory replay double-free
A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_query_directory_init() fails before the next send,
cleanup retains the previous buffer type and frees that response again.
Reset response bookkeeping before each attempt to prevent the stale free.

smb: client: fix double-free in SMB2_flush() replay
SMB2_flush() keeps its response buffer bookkeeping across replay
attempts. If a replayable flush response is received and the retry then
fails before cifs_send_recv() stores a replacement response, flush_exit
will free the stale response pointer a second time.
Reinitialize resp_buftype and rsp_iov at the top of the replay loop so
cleanup only acts on response state produced by the current attempt.
This fixes a double-free without changing replay handling for successful
requests.

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.

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: drivers for 7.2
There are a few added drivers, but mostly the normal maintenance to drivers
for firmware, memory controller and other soc specific hadware:
- The NXP QuickEngine gets modern MSI support, which allows some cleanups to
the GICv3 irqchip chip driver
- A new SoC specific driver for the Renesas R-Car MFIS unit is added,
encapsulating support for the on-chip mailbox and hwspinlock
implementations that are not easily separated into individual
drivers
- The Qualcomm SoC drivers add support for additional SoC implementations,
and flexiblity around power managedment for the serial-engine driver
as well as probing the LLCC driver using custom hardware descriptions
inside of the device itself.
- Added support for the Samsung thermal management unit
- A cleanup to the Tegra 'PMC' driver interfaces to remove legacy
APIs and allow multiple PMC instances everywhere.
- Updates to the TI SCI and KNAS drivers to improve suspend/resume
support.
- Minor driver changes for mediatek, xilinx, allwinner, aspeed, tegra,
broadcom, amd, microchip and starfive specific drivers
- Memory controller updates for Tegra and Renesas for additional SoC
types and other improvements.
- Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces,
to update driver probing, object lifetimes and address minor bugs.

Pull SoC driver updates from Arnd Bergmann:
"There are a few added drivers, but mostly the normal maintenance to
drivers for firmware, memory controller and other soc specific
hardware:
- The NXP QuickEngine gets modern MSI support, which allows some
cleanups to the GICv3 irqchip chip driver
- A new SoC specific driver for the Renesas R-Car MFIS unit is added,
encapsulating support for the on-chip mailbox and hwspinlock
implementations that are not easily separated into individual
drivers
- The Qualcomm SoC drivers add support for additional SoC
implementations, and flexibility around power management for the
serial-engine driver as well as probing the LLCC driver using
custom hardware descriptions inside of the device itself.
- Added support for the Samsung thermal management unit
- A cleanup to the Tegra 'PMC' driver interfaces to remove legacy
APIs and allow multiple PMC instances everywhere.
- Updates to the TI SCI and KNAS drivers to improve suspend/resume
support.
- Minor driver changes for mediatek, xilinx, allwinner, aspeed,
tegra, broadcom, amd, microchip and starfive specific drivers
- Memory controller updates for Tegra and Renesas for additional SoC
types and other improvements.
- Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces, to
update driver probing, object lifetimes and address minor bugs"

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.

- Avoid nontransitive comparisons comparisons in our sorting code
Done to prevent unexpected sorting results due to overflow. Qualys
documented a similar issue with glibc

- Consistently use u16 for SELinux security classes
- Move from page allocations to kmalloc() based allocations

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.

cgroup: Changes for v7.2
- Last cycle deferred css teardown on cgroup removal until the cgroup depopulated, so a css is not taken offline while tasks can still reference it.

workqueue: Changes for v7.2
- Continued progress toward making alloc_workqueue() unbound by default:
more callers converted to WQ_PERCPU / system_percpu_wq / system_dfl_wq,
and new warnings for queues that use neither WQ_PERCPU nor WQ_UNBOUND
or the legacy system_wq / system_unbound_wq.
- Misc: drop the now-trivial apply_wqattrs_lock()/unlock() wrappers,
forbid the TEST_WORKQUEUE benchmark from being built-in, and fix a
spurious pointer level in the worker debug-dump path.

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.

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)

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)

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).

- support Socket Direct (multi-PF) with switchdev offloads

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.

configuration
- support Socket Direct (multi-PF) with switchdev offloads

ksmbd: fix path resolution in ksmbd_vfs_kern_path_create
The SMB2 open lookup is rooted at the share with LOOKUP_BENEATH, but the
create/mkdir/hardlink sink is not: ksmbd_vfs_kern_path_create() builds an
absolute path with convert_to_unix_name() and resolves it from AT_FDCWD
via start_creating_path(), so a ".." component is walked from the real
filesystem root and escapes the export.
An authenticated client races a missing path component so the rooted open
lookup returns -ENOENT (taking the create branch) while the same component
is present (a directory) when the create walk runs; the create then
resolves ".." out of the share.
Root the create walk at the share like the lookup and rename paths already
are: resolve the parent with vfs_path_parent_lookup(..., LOOKUP_BENEATH,
&share_conf->vfs_path) and create the final component with
start_creating_noperm(). convert_to_unix_name() then has no callers and is
removed.
Fixes:

ksmbd: use opener credentials for FSCTL mutations
SET_SPARSE, SET_ZERO_DATA and SET_COMPRESSION operate on an open SMB handle but call VFS xattr, fallocate or fileattr helpers with the current ksmbd worker credentials. Those helpers can revalidate inode permissions, ownership and LSM policy independently of the SMB handle access mask. Run each operation with the credentials captured in the target file when the handle was opened. Keep credential handling local to these single-file FSCTLs rather than applying session credentials to the complete IOCTL handler, which also contains handle-less and multi-handle operations.

ksmbd: use opener credentials for ADS I/O
Alternate data streams are stored as xattrs. Unlike regular file I/O, their read and write paths therefore call VFS xattr helpers which recheck inode permissions and LSM policy using the current task credentials. Run ADS I/O with the credentials captured when the SMB handle was opened.

ksmbd: require source read access for duplicate extents
FSCTL_DUPLICATE_EXTENTS_TO_FILE passes the source file directly to vfs_clone_file_range() or vfs_copy_file_range() without checking the SMB access mask granted to the source handle. A handle opened with attribute access can consequently be used to copy file contents into an attacker-readable destination. Require FILE_READ_DATA on the source handle before either VFS operation, matching other ksmbd data-copy paths.
