ksmbd: fix durable reconnect context parsing
SMB2 create context DataLength describes only the create context data payload. It does not include the create context header, name field, or any local padding that exists in ksmbd's helper structures. ksmbd validated durable reconnect contexts by comparing DataOffset + DataLength against sizeof the whole helper structure. This rejects a valid durable v2 reconnect context because the wire DH2C data is 36 bytes while struct create_durable_handle_reconnect_v2 contains an extra four byte pad. Validate the durable context payload length against the corresponding payload member instead. Also keep the reconnect context authoritative when a later durable request context is present, matching the existing durable v1 reconnect behavior. This fixes smbtorture smb2.durable-v2-open.durable-v2-setinfo, where the durable v2 reconnect after SET_INFO was rejected with STATUS_INVALID_PARAMETER.

ksmbd: invalidate durable handles on oplock break
When a durable handle is preserved after a disconnect, its oplock state can still block later opens. If another client opens the same file and the preserved oplock or lease has to be broken, the old durable handle must no longer be reconnectable after the break cannot be acknowledged. ksmbd was treating a missing connection, or an oplock break timeout, as a successful break only by downgrading the oplock state. The old durable handle remained reconnectable, so a later durable reconnect for that stale handle could succeed. The open path can also see a detached durable handle before the break notification helpers fully dispose of it. Invalidate such a preserved durable handle directly when a competing open has to break its batch or exclusive oplock, while leaving ordinary durable reconnects without a competing open untouched. If the old handle still reaches the reconnect path, reject it when the same inode already has another active open. This matches the smb2.durable-open.open2-lease/open2-oplock sequence where a later open replaces the disconnected durable owner and the stale first handle must not be reclaimed. Also, reconnect lookup used only the persistent id. A new durable open can get a persistent id that matches the stale reconnect request after the old durable state is invalidated. Preserve the disconnected handle's old volatile id and require durable reconnect contexts to match it, so a stale reconnect cannot attach to a different durable open. Windows allows the later open to proceed and rejects the old reconnect with STATUS_OBJECT_NAME_NOT_FOUND. The smbtorture smb2.durable-open.oplock test covers this case.

ksmbd: supersede disconnected delete-on-close durable handle
A durable handle opened with FILE_DELETE_ON_CLOSE is preserved across a disconnect so it can be reclaimed by a durable reconnect. smb2.durable-open.delete_on_close2 disconnects such a handle and then reconnects it, expecting the reconnect to succeed. When the client does not reconnect but instead opens the same name with a new delete-on-close create, the preserved handle keeps the file present with delete-on-close set. ksmbd then rejects the new open with STATUS_ACCESS_DENIED on the file_present + FILE_DELETE_ON_CLOSE + OPEN_IF/OVERWRITE_IF path. smb2.durable-open.delete_on_close1 expects this open to create a fresh, empty file instead, i.e. the disconnected handle's delete-on-close must take effect first. Add ksmbd_close_disconnected_durable_delete_on_close(), which closes disconnected (conn == NULL) durable handles that keep a delete-on-close file present. The final close promotes S_DEL_ON_CLS to S_DEL_PENDING and unlinks the file, so a re-resolved path is absent and the new open creates it fresh. Call it from smb2_open() before the delete-on-close conflict check, only for the conflicting open shapes. A live (connected) handle still keeps the file and blocks the open as before.

ksmbd: handle missing create contexts for lease opens
smb2_find_context_vals() assumes that callers only search create contexts when the SMB2 CREATE request contains a non-empty create context area. That is not always true. a client can send RequestedOplockLevel set to SMB2_OPLOCK_LEVEL_LEASE without a lease create context. In that case parse_lease_state() searches for a lease context and smb2_find_context_vals() starts parsing from offset 0 with length 0, returning -EINVAL. This makes the open fail with STATUS_INVALID_PARAMETER. The smbtorture smb2.lease.duplicate_open test hits this while creating a second file without a lease request. Return NULL when the request has no create context area so the missing context is treated the same as any other absent create context. The open then continues without granting a lease.

ksmbd: fix use-after-free of conn->preauth_info in concurrent SMB2 NEGOTIATE
conn->preauth_info is shared connection state (struct
preauth_integrity_info, kmalloc-96) that is allocated and freed by the
SMB2 NEGOTIATE handler and read by the response send path.
smb2_handle_negotiate() allocates conn->preauth_info, and on a
deassemble_neg_contexts() failure kfrees it and sets it to NULL. Both the
allocation and the free/NULL happen under ksmbd_conn_lock(conn) (the
connection srv_mutex), which is held across the whole handler body.
The response send path smb3_preauth_hash_rsp(), called from the send:
block of __handle_ksmbd_work(), reads conn->preauth_info and dereferences
conn->preauth_info->Preauth_HashValue (via
ksmbd_gen_preauth_integrity_hash()) without taking conn_lock. When a
client drives two SMB2 NEGOTIATE requests on the same connection, one
worker can free conn->preauth_info on the failing-negotiate path while a
concurrent send-path worker is reading it, producing a slab
use-after-free read (KASAN-confirmed).
The send-path read tested conn->preauth_info for NULL but raced with the
free that occurs between the NULL check and the dereference, so the NULL
guard alone does not close the window.
Serialize the NEGOTIATE-branch read in smb3_preauth_hash_rsp() under
ksmbd_conn_lock(conn) and re-check conn->preauth_info inside the lock.
Because the negotiate handler holds conn_lock across its kfree + NULL
assignment, a reader that also takes conn_lock either runs fully before
the allocation or fully after the NULL store, and can never observe the
freed-but-not-yet-NULLed pointer. ksmbd_gen_preauth_integrity_hash()
takes no locks itself (it only computes a SHA-512 over the buffer), so
no lock-ordering inversion is introduced, and conn_lock is a sleepable
mutex which is safe on this send path (it already performs network I/O).

ksmbd: keep common response iovecs in the work item
Most SMB responses need no more than four kvec entries, but every work item currently allocates a separate four-entry array and frees it after the response is sent. Embed the common array in struct ksmbd_work and allocate a larger array only when a response exceeds the inline capacity. This removes one allocation and one free from the common request path while preserving support for larger compound and read responses.

ksmbd: route v2 lease breaks on the client lease channel
v2 leases are scoped by ClientGuid. When the same client uses multiple connections, smbtorture expects lease break notifications to be sent on the connection associated with the client lease table, not necessarily on the connection that owns the individual open being broken. Keep a referenced connection in the lease table and use it for v2 lease break notifications while it is still active. Fall back to the open's connection if the table connection is being released.

ksmbd: break RH leases before delete-on-close
The delete paths only marked the opened file delete pending or delete-on-close. When another client still held a read/handle lease, no lease break was sent before the delete state changed. smb2.lease.unlink uses a create request with FILE_DELETE_ON_CLOSE and expects the second client's unlink to break the first client's RH lease to R with ACK_REQUIRED set. SetInfo(FileDispositionInformation) has the same lease-breaking requirement. Break level-II/read-handle leases before setting delete pending or delete-on-close so clients are notified before the file is removed.

ksmbd: honor SMB2 v2 lease epochs
v2 lease responses should continue from the client supplied epoch. Initialize a new v2 lease from the requested epoch plus one so create responses match the epoch returned by Windows and expected by smbtorture. For a single chained break sequence, increment the epoch only for the first break notification. Follow-up breaks such as RH->R and R->NONE in smb2.lease.v2_breaking3 reuse the same epoch. Record when a waiter slept behind pending_break and let the later truncate/open overwrite break consume that marker to reuse the current epoch instead of assigning a new one. Do not increment the epoch when a same-client, same-key create asks for the already granted RH state. The epoch changes only when the granted lease state changes.

ksmbd: chain pending lease breaks before waking waiters
A pending open can require more than one lease break before the existing lease becomes compatible with the operation that triggered the break. smb2.lease.breaking3 expects the server to hold the pending normal open through RWH->RH and RH->R, while a later overwrite waiter must not collapse that second break directly to RH->NONE. Keep pending_break held for lease breaks until the current triggering operation is compatible with the lease state. Snapshot the truncate request per oplock_break() call so another waiter cannot overwrite the state of the active break. Use the requested oplock level when deciding whether to chain another break. A second lease open only needs RWH->RH, while a normal none-oplock open can continue down to R and then NONE. For non-truncating metadata operations, break leases only down to read caching. Operations such as delete-on-close need to drop handle caching, but should not send a second R->NONE break after the client acknowledges RH->R. Also send STATUS_PENDING for levelII/read-lease break waiters. An async SMB2 create becomes cancelable only after the server sends an NT_STATUS_PENDING interim response. A waiter that blocks behind an already active lease break must receive the interim response before sleeping on pending_break, otherwise the client can process a later lease break while the create request is still not marked pending. Avoid duplicate interim responses when an overwrite first breaks a write oplock and then scans levelII/read leases.

ksmbd: compute lease break-in-progress flag on response
SMB2_LEASE_FLAG_BREAK_IN_PROGRESS is a transient create response flag, not persistent lease state. Do not store the flag in lease->flags when a same-key open is granted during a pending break. Instead, derive it from lease opens that are still waiting for a break ACK while building the lease create response, and keep lease->flags for persistent lease flags such as the parent lease key. This clears the flag naturally after the break ACK completes and fixes reopen responses that report BREAK_IN_PROGRESS after the lease is no longer breaking.

ksmbd: share SMB2 lease state across opens
Model SMB2 leases as per-client/per-key objects instead of keeping a separate lease copy in every oplock_info. The lease table now stores lease objects and each lease tracks the opens that reference it. This makes same ClientGuid/LeaseKey opens observe a single lease state, so lease upgrades, breaks, ACKs, and close teardown do not diverge across per-open copies. Keep one reference for the lease table entry and one reference for each open, and remove the table entry when the last open is detached.

ksmbd: track the connection owning a byte-range lock
SMB2_LOCK adds each granted byte-range lock to both the file lock list
and the lock list of the connection which handled the request. The
final close and durable handle paths, however, remove the connection
list entry while holding fp->conn->llist_lock.
With SMB3 multichannel, the connection handling the LOCK request can be
different from the connection which opened the file. The entry can
therefore be removed under a different spinlock from the one protecting
the list it belongs to. A concurrent traversal can then access freed
struct ksmbd_lock and struct file_lock objects.
Record the connection owning each lock's clist entry and hold a
reference to it while the entry is linked. Use that connection and its
llist_lock for unlock, rollback, close, and durable preserve. Durable
reconnect assigns the new connection as the owner when publishing the
locks again.

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.

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.

RDMA v7.2 merge window
Many AI driven bug fixes, and several big driver API cleanups
- Driver bug fixes and minor cleanups in mlx5, hns, rxe, efa, siw, rtrs,
mana, irdma, mlx4. Commonly error path flows, integer arithmetic
overflows on unsafe data, out of bounds access, and use after free
issues under races.
- Second half of the new udata API for drivers focusing on uAPI response
- bnxt_re supports more options for QP creation that will allow a dv
path in rdma-core
- Untangle the module dependencies so drivers don't link to ib_uverbs.ko
as was originall intended
- Provide a new way to handle umems with a consistent simplified uAPI and
update several drivers to use it. This brings dmabuf support to more
places and more drivers
- Support for mlx5 rate limit and packet pacing for UD and UC
- A batch of fixes for the new shared FRMR pools infrastructure

memblock: updates for 7.2-rc1
Small fixes and a cleanup:
* numa emulation: fix detection of under-allocated emulated nodes
* memblock tests: fix NUMA tests to properly differentiate reserved areas
with differnet flags
* mm_init: use div64_ul() instead of do_div() to better express the intent
of the division

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.
(David Matlack)

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.

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.

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

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.
