usb: host: xhci-sideband: delegate offload_usage tracking to class drivers
Remove usb_offload_get() and usb_offload_put() from the xHCI sideband
interrupter creation and removal paths.
The responsibility of manipulating offload_usage now lies entirely with
the USB class drivers. They have the precise context of when an offload
data stream actually starts and stops, ensuring a much more accurate
representation of offload activity for power management.

usb: core: use dedicated spinlock for offload state
Replace the coarse USB device lock with a dedicated offload_lock
spinlock to reduce contention during offload operations. Use
offload_pm_locked to synchronize with PM transitions and replace
the legacy offload_at_suspend flag.
Optimize usb_offload_get/put by switching from auto-resume/suspend
to pm_runtime_get_if_active(). This ensures offload state is only
modified when the device is already active, avoiding unnecessary
power transitions.

usb: cdns3: gadget: fix state inconsistency on gadget init failure
When cdns3_gadget_start() fails, the DRD hardware is left in gadget mode
while software state remains INACTIVE, creating hardware/software state
inconsistency.
When switching to host mode via sysfs:
echo host > /sys/class/usb_role/13180000.usb-role-switch/role
The role state is not set to CDNS_ROLE_STATE_ACTIVE due to the error,
so cdns_role_stop() skips cleanup because state is still INACTIVE.
This violates the DRD controller design specification (Figure22),
which requires returning to idle state before switching roles.
This leads to a synchronous external abort in xhci_gen_setup() when
setting up the host controller:

usb: dwc3: imx8mp: fix memory leak on probe failure path
When platform_get_drvdata() returns NULL and probe defers, the error

usb: gadget: f_uac1_legacy: validate control request size
f_audio_complete() copies req->length bytes into a 4-byte stack variable: u32 data = 0; memcpy(&data, req->buf, req->length); req->length is derived from the host-controlled USB request path, which can lead to a stack out-of-bounds write. Validate req->actual against the expected payload size for the supported control selectors and decode only the expected amount of data. This avoids copying a host-influenced length into a fixed-size stack object.

usb: ulpi: fix double free in ulpi_register_interface() error path
When device_register() fails, ulpi_register() calls put_device() on
ulpi->dev.
The device release callback ulpi_dev_release() drops the OF node
reference and frees ulpi, but the current error path in
ulpi_register_interface() then calls kfree(ulpi) again, causing a
double free.
Let put_device() handle the cleanup through ulpi_dev_release() and
avoid freeing ulpi again in ulpi_register_interface().

USB: core: add NO_LPM quirk for Razer Kiyo Pro webcam
The Razer Kiyo Pro (1532:0e05) is a USB 3.0 UVC webcam whose firmware does not handle USB Link Power Management transitions reliably. When LPM is active, the device can enter a state where it fails to respond to control transfers, producing EPIPE (-32) errors on UVC probe control SET_CUR requests. In the worst case, the stalled endpoint triggers an xHCI stop-endpoint command that times out, causing the host controller to be declared dead and every USB device on the bus to be disconnected. This has been reported as Ubuntu Launchpad Bug #2061177. The failure mode is: 1. UVC probe control SET_CUR returns -32 (EPIPE) 2. xHCI host not responding to stop endpoint command 3. xHCI host controller not responding, assume dead 4. All USB devices on the affected xHCI controller disconnect Disabling LPM prevents the firmware from entering the problematic low- power states that precede the stall. This is the same approach used for other webcams with similar firmware issues (e.g., Logitech HD Webcam C270).

usb: cdns3: gadget: fix NULL pointer dereference in ep_queue
When the gadget endpoint is disabled or not yet configured, the ep->desc
pointer can be NULL. This leads to a NULL pointer dereference when
__cdns3_gadget_ep_queue() is called, causing a kernel crash.
Add a check to return -ESHUTDOWN if ep->desc is NULL, which is the
standard return code for unconfigured endpoints.
This prevents potential crashes when ep_queue is called on endpoints
that are not ready.

usb: gadget: f_rndis: Fix net_device lifecycle with device_move
The net_device is allocated during function instance creation and
registered during the bind phase with the gadget device as its sysfs
parent. When the function unbinds, the parent device is destroyed, but
the net_device survives, resulting in dangling sysfs symlinks:
console:/ # ls -l /sys/class/net/usb0
lrwxrwxrwx ... /sys/class/net/usb0 ->
/sys/devices/platform/.../gadget.0/net/usb0
console:/ # ls -l /sys/devices/platform/.../gadget.0/net/usb0
ls: .../gadget.0/net/usb0: No such file or directory
Use device_move() to reparent the net_device between the gadget device
tree and /sys/devices/virtual across bind and unbind cycles. During the
final unbind, calling device_move(NULL) moves the net_device to the
virtual device tree before the gadget device is destroyed. On rebinding,
device_move() reparents the device back under the new gadget, ensuring
proper sysfs topology and power management ordering.
To maintain compatibility with legacy composite drivers (e.g., multi.c),
the borrowed_net flag is used to indicate whether the network device is
shared and pre-registered during the legacy driver's bind phase.

usb: typec: thunderbolt: Set enter_vdo during initialization
In the current implementation, if a cable's alternate mode enter operation
is not supported, the tbt->plug[TYPEC_PLUG_SOP_P] pointer is cleared by the
time tbt_enter_mode() is called. This prevents the driver from identifying
the cable's VDO.
As a result, the Thunderbolt connection falls back to the default
TBT_CABLE_USB3_PASSIVE speed, even if the cable supports higher speeds.
To ensure the correct VDO value is used during mode entry, calculate and

usb: dwc2: gadget: Fix spin_lock/unlock mismatch in dwc2_hsotg_udc_stop()
dwc2_gadget_exit_clock_gating() internally calls call_gadget() macro,
which expects hsotg->lock to be held since it does spin_unlock/spin_lock
around the gadget driver callback invocation.
However, dwc2_hsotg_udc_stop() calls dwc2_gadget_exit_clock_gating()
without holding the lock. This leads to:
- spin_unlock on a lock that is not held (undefined behavior)
- The lock remaining held after dwc2_gadget_exit_clock_gating() returns,
causing a deadlock when spin_lock_irqsave() is called later in the
same function.
Fix this by acquiring hsotg->lock before calling
dwc2_gadget_exit_clock_gating() and releasing it afterwards, which
satisfies the locking requirement of the call_gadget() macro.

usb: gadget: dummy_hcd: fix premature URB completion when ZLP follows partial transfer
When a gadget request is only partially transferred in transfer()
because the per-frame bandwidth budget is exhausted, the loop advances
to the next queued request. If that next request is a zero-length
packet (ZLP), len evaluates to zero and the code takes the
unlikely(len == 0) path, which sets is_short = 1. This bypasses the
bandwidth guard ("limit < ep->ep.maxpacket && limit < len") that
lives in the else branch and would otherwise break out of the loop for
non-zero requests. The is_short path then completes the URB before all
data from the first request has been transferred.
Reproducer (bulk IN, high speed):
Device side (FunctionFS with Linux AIO):
1. Queue a 65024-byte write via io_submit (127 * 512, i.e. a
multiple of the HS bulk max packet size).
2. Immediately queue a zero-length write (ZLP) via io_submit.
Host side:
3. Submit a 65536-byte bulk IN URB.
Expected: URB completes with actual_length = 65024.
Actual: URB completes with actual_length = 53248, losing 11776
bytes that leak into subsequent URBs.
At high speed the per-frame budget is 53248 bytes (512 * 13 * 8).
The 65024-byte request exhausts this budget after 53248 bytes, leaving
the request incomplete (req->req.actual < req->req.length). Neither
the request nor the URB is finished, and rescan is 0, so the loop
advances to the ZLP. For the ZLP, dev_len = 0, so len = min(12288, 0)
= 0, taking the unlikely(len == 0) path and setting is_short = 1.
The is_short handler then sets *status = 0, completing the URB with
only 53248 of the expected 65024 bytes.
Fix this by breaking out of the loop when the current request has
remaining data (req->req.actual < req->req.length). The request
resumes on the next timer tick, preserving correct data ordering.

usb: gadget: u_ether: Fix race between gether_disconnect and eth_stop
A race condition between gether_disconnect() and eth_stop() leads to a
NULL pointer dereference. Specifically, if eth_stop() is triggered
concurrently while gether_disconnect() is tearing down the endpoints,
eth_stop() attempts to access the cleared endpoint descriptor, causing
the following NPE:

dwc3_gadget_ep_enable+0x70/0xe4
usb_ep_enable+0x60/0x15c
eth_stop+0xb8/0x108
Because eth_stop() crashes while holding the dev->lock, the thread
running gether_disconnect() fails to acquire the same lock and spins
forever, resulting in a hardlockup:

The root cause is that the clearing of dev->port_usb in
gether_disconnect() is delayed until the end of the function.
Move the clearing of dev->port_usb to the very beginning of

immediately, ensuring eth_stop() will see dev->port_usb as NULL and

ARM:
- Correctly handle deeactivation of interrupts that were activated from
LRs. Since EOIcount only denotes deactivation of interrupts that
are not present in an LR, start EOIcount deactivation walk *after*
the last irq that made it into an LR.
- Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when
pKVM is already enabled -- not only thhis isn't possible (pKVM
will reject the call), but it is also useless: this can only
happen for a CPU that has already booted once, and the capability
will not change.
- Fix a couple of low-severity bugs in our S2 fault handling path,
affecting the recently introduced LS64 handling and the even more
esoteric handling of hwpoison in a nested context
- Address yet another syzkaller finding in the vgic initialisation,
where we would end-up destroying an uninitialised vgic with nasty
consequences
- Address an annoying case of pKVM failing to boot when some of the
memblock regions that the host is faulting in are not page-aligned
- Inject some sanity in the NV stage-2 walker by checking the limits
against the advertised PA size, and correctly report the resulting
faults
PPC:
- Fix a PPC e500 build error due to a long-standing wart that was exposed by
the recent conversion to kmalloc_obj(); rip out all the ugliness that
led to the wart.
RISC-V:
- Prevent speculative out-of-bounds access using array_index_nospec()
in APLIC interrupt handling, ONE_REG regiser access, AIA CSR access,
float register access, and PMU counter access
- Fix potential use-after-free issues in kvm_riscv_gstage_get_leaf(),
kvm_riscv_aia_aplic_has_attr(), and kvm_riscv_aia_imsic_has_attr()
- Fix potential null pointer dereference in kvm_riscv_vcpu_aia_rmw_topei()
- Fix off-by-one array access in SBI PMU
- Skip THP support check during dirty logging
- Fix error code returned for Smstateen and Ssaia ONE_REG interface
- Check host Ssaia extension when creating AIA irqchip
x86:
- Fix cases where CPUID mitigation features were incorrectly marked as
available whenever the kernel used scattered feature words for them.
- Validate _all_ GVAs, rather than just the first GVA, when processing
a range of GVAs for Hyper-V's TLB flush hypercalls.
- Fix a brown paper bug in add_atomic_switch_msr().
- Use hlist_for_each_entry_srcu() when traversing mask_notifier_list,
to fix a lockdep warning; KVM doesn't hold RCU, just irq_srcu.
- Ensure AVIC VMCB fields are initialized if the VM has an in-kernel local
APIC (and AVIC is enabled at the module level).
- Update CR8 write interception when AVIC is (de)activated, to fix a bug
where the guest can run in perpetuity with the CR8 intercept enabled.
- Add a quirk to skip the consistency check on FREEZE_IN_SMM, i.e. to allow
L1 hypervisors to set FREEZE_IN_SMM. This reverts (by default) an
unintentional tightening of userspace ABI in 6.17, and provides some
amount of backwards compatibility with hypervisors who want to freeze
PMCs on VM-Entry.
- Validate the VMCS/VMCB on return to a nested guest from SMM, because
either userspace or the guest could stash invalid values in memory
and trigger the processor's consistency checks.
Generic:
- Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from being
unnecessary and confusing, triggered compiler warnings due to
-Wflex-array-member-not-at-end.
- Document that vcpu->mutex is take outside of kvm->slots_lock and
kvm->slots_arch_lock, which is intentional and desirable despite being
rather unintuitive.
Selftests:
- Increase the maximum number of NUMA nodes in the guest_memfd selftest to
64 (from 8).

Pull kvm fixes from Paolo Bonzini:
"Quite a large pull request, partly due to skipping last week and
therefore having material from ~all submaintainers in this one. About
a fourth of it is a new selftest, and a couple more changes are large
in number of files touched (fixing a -Wflex-array-member-not-at-end
compiler warning) or lines changed (reformatting of a table in the API
documentation, thanks rST).
But who am I kidding---it's a lot of commits and there are a lot of
bugs being fixed here, some of them on the nastier side like the
RISC-V ones.

More MM-CID fixes, mostly fixing hangs/races:
- Fix CID hangs due to a race between concurrent forks
- Fix vfork()/CLONE_VM MMCID bug causing hangs
- Remove pointless preemption guard
- Fix CID task list walk performance regression on large systems
by removing the known-flaky and slow counting logic using
for_each_process_thread() in mm_cid_*fixup_tasks_to_cpus(),
and implementing a simple sched_mm_cid::node list instead

Rust fixes for v7.0 (2nd)
Toolchain and infrastructure:
- Remap paths to avoid absolute ones starting with the upcoming Rust
1.95.0 release. This improves build reproducibility, avoids leaking
the exact path and avoids having the same path appear in two forms.
The approach here avoids remapping debug information as well, in
order to avoid breaking tools that used the paths to access source
files, which was the previous attempt that needed to be reverted.
- Allow 'unused_features' lint for the upcoming Rust 1.96.0 release.
While well-intentioned, we do not benefit much from the new lint.
- Emit dependency information into '$(depfile)' directly to avoid
a temporary '.d' file (it was an old approach).
'kernel' crate:
- 'str' module: fix warning under '!CONFIG_BLOCK' by making
'NullTerminatedFormatter' public.
- 'cpufreq' module: suppress false positive Clippy warning.
'pin-init' crate:
- Remove '#[disable_initialized_field_access]' attribute which was
unsound. This means removing the support for structs with unaligned
fields (through the 'repr(packed)' attribute), for now.
And document the load-bearing fact of field accessors (i.e. that they
are required for soundness).
- Replace shadowed return token by 'unsafe'-to-create token in order
to remain sound in the face of the likely upcoming Type Alias Impl
Trait (TAIT) and the next trait solver in upstream Rust.

USB fixes for 7.0-rc4
Here is a large chunk of USB driver fixes for 7.0-rc4. Included in here
are:
- usb gadget reverts due to reported issues, and then a follow-on fix
to hopefully resolve the reported overall problem
- xhci driver fixes
- dwc3 driver fixes
- usb core "killable" bulk message api addition to fix a usbtmc driver
bug where userspace could hang the driver for forever
- small USB driver fixes for reported issues
- new usb device quirks
All except the last USB device quirk change have been in linux-next with
no reported issues. That one came in too late, and is "obviously
correct" :)
