The driver submits the read urbs for all ports when the first port is
opened, which could happen before the other ports have been probed and
their private data set up.
If such an urb completes before the port has been probed, the completion
handler will not resubmit it, thus preventing any further reads.
Fix the ordering issue by not submitting the port read urbs until the
port is opened.
This also avoids wasting resources (e.g. power) when ports are not in
use.
Note that the port write urbs are already stopped on close (unless
unbinding, but they are also stopped by core on disconnect).

Stopping an urb is not an error and should not be logged as such.
Demote the dev_err() in the read bulk completion handler to dev_dbg()
when an urb is being unlinked on disconnect.
Note that this will become more of an issue when the urbs are stopped
every time a port is closed.
This issue was flagged by Sashiko when reviewing the upcoming change.

dma_iova_destroy() frees the IOVA space through __iommu_dma_iova_unlink()
using a "free_iova" boolean, which duplicates the IOVA free logic in
dma_iova_free(). And it frees using the unmapped @mapped_len, which for a
partially linked reservation is smaller than the reserved size. This
results in a benign waste as pointed out by Robin, not a leak. So this is
a cleanup, not a fix.
Drop the duplicated free path. Fold __iommu_dma_iova_unlink into
dma_iova_unlink and remove the free_iova parameter so it only unmaps.
dma_iova_destroy then unlinks the mapped range if mapped_len is set and
unconditionally calls dma_iova_free, which frees the whole reservation
via dma_iova_size. The freed size now always matches the reserved size,
and destroy reads as unlink then free.
Note that dma_iova_destroy() no longer routes the free through the flush
queue; teardown now unmaps synchronously and frees directly, matching
dma_iova_free().
No functional change intended for callers.

The hand-rolled bit-scanning loop in the NCQ completion path has an
infinite loop bug. When tag_mask has only high bits set (e.g.
0x80000000), the inner while loop left-shifts tag_mask until it
overflows to 0. At that point !(0 & 1) is always true and 0 <<= 1
stays 0, causing an infinite loop in hardirq context with a spinlock
held.
Replace the open-coded bit-scanning with __ffs() which correctly
finds the least significant set bit and is bounded by the width of
the argument.

clear_interrupt_bit() ignores the bit argument and performs a
read-write-back of the entire INTPR register. If INTPR uses standard
Write-1-to-Clear semantics, this clears every pending interrupt bit,
not just the intended one. Coalesced interrupts (e.g. DMAT + NEWFP)
would be cleared together, silently losing the second event.
Write only the specific bit to clear so that other pending interrupts
are preserved.

sata_dwc_enable_interrupts() is called before platform_get_irq() and
ata_host_activate(), leaving the SATA controller's interrupt mask
enabled without a registered handler. If a later step fails (irq
request, phy init, etc.) or if the controller asserts an interrupt
during probe, the irq line may fire with no handler, causing a
spurious interrupt storm.
Move sata_dwc_enable_interrupts() after ata_host_activate() so that
interrupts are only unmasked once the handler is registered and the
core is fully initialized.

printer_read() uses the same variable for the requested copy size and
the number of bytes actually copied to user space. copy_to_user()
returns the number of bytes not copied, so when it fails to copy
anything, the computed copied length becomes zero.
In that case len, buf, current_rx_bytes and current_rx_buf are left
unchanged. If RX data is available and the user buffer remains
unwritable, the read loop can repeat indefinitely.
Track the copied length separately and return -EFAULT, or the number of
bytes already copied, if an iteration makes no progress.

The f_midi driver embeds a work item (midi->work) whose handler,
f_midi_in_work(), dereferences the enclosing struct f_midi through
container_of(). This work is armed from two sites: f_midi_complete(),
on a normal IN-endpoint completion, and f_midi_in_trigger(), on an ALSA
rawmidi output-stream start.
Neither f_midi_disable() nor f_midi_unbind() cancels midi->work.
f_midi_disable() only disables the endpoints and drains the in_req_fifo;
it does not synchronize the work item, and the sound card is released
asynchronously to the final free of the midi object.
The midi object is reference-counted (midi->free_ref) and is freed in
f_midi_free() only once both the usb_function reference and the rawmidi
private_data reference have been dropped. In f_midi_unbind(),
f_midi_disable() runs before the sound card is released, so while the
USB endpoints are already disabled the rawmidi device is still usable by
an open substream. A concurrent userspace write on such a substream can
reach f_midi_in_trigger() and queue midi->work again after
f_midi_disable() has returned. A work item armed this way may still be
pending when the last reference drops and f_midi_free() proceeds to
kfree(midi), letting f_midi_in_work() dereference the struct after it
has been freed, a use-after-free.
For this reason cancelling midi->work in f_midi_disable() would not be
sufficient: the ALSA trigger path can rearm the work after disable()
returns. Cancelling at the refcount-zero free site is the boundary
after which neither arming source can survive, because by then both
references that keep the midi object alive have been dropped: the USB
endpoints are already disabled and the rawmidi device has been released.
Fix this by calling cancel_work_sync(&midi->work) in the refcount-zero
block of f_midi_free(), before the embedded work_struct is freed along
with the rest of the structure. opts->lock is a sleeping mutex, so
calling cancel_work_sync() under it is permitted, and the handler takes
midi->transmit_lock rather than opts->lock, so no self-deadlock can
occur while it waits for a running instance of the work to finish.
This issue was found by an in-house static analysis tool.

The Broadcom BDC UDC driver registers its IRQ handler with
devm_request_irq() in bdc_udc_init(), so the IRQ is released by devm
only after bdc_remove() returns. devm releases resources in reverse
LIFO order, but bdc_remove() runs bdc_udc_exit() and bdc_hw_exit() ->
bdc_mem_free() manually before returning: bdc_udc_exit() tears down
individual endpoint objects via bdc_free_ep(), while bdc_hw_exit() ->
bdc_mem_free() frees and NULLs the DMA-coherent status-report ring
(bdc->srr.sr_bds) and kfree()s bdc->bdc_ep_array. Both happen while
the IRQ handler (bdc_udc_interrupt, requested with IRQF_SHARED)
remains deliverable in the window up to the post-remove devm
free_irq().
On receipt of a shared interrupt in that window, bdc_udc_interrupt()
dereferences bdc->srr.sr_bds[bdc->srr.dqp_index] (NULL or freed DMA)
and dispatches sr_handler callbacks that index into bdc_ep_array,
causing a NULL-deref or use-after-free.
The same window affects the delayed_work bdc->func_wake_notify, which is
armed from the IRQ handler via bdc_sr_uspc() -> handle_link_state_change()
-> schedule_delayed_work() and may self-rearm from its own callback
bdc_func_wake_timer(). No cancel exists anywhere in the driver, so a
queued work item that fires after bdc_remove() returns and the bdc
structure is devm-freed dereferences freed memory.
Replace devm_request_irq() with request_irq() and add an explicit
free_irq(bdc->irq, bdc) in bdc_remove(). Clear BDC_GIE before
free_irq() to stop the device from asserting interrupts, then
free_irq() drains any in-flight handler, then cancel_delayed_work_sync()
drains the func_wake_notify delayed work. This ordering ensures the
IRQ handler and delayed work cannot interfere with the subsequent
endpoint and DMA teardown in bdc_udc_exit() and bdc_hw_exit(). Wire the
matching free_irq() into the bdc_udc_init() error path so the IRQ is
released on probe failure, and route the bdc_init_ep() failure through
err0 instead of returning directly.
This issue was found by an in-house static analysis tool.

A synchronization issue exists during port unregistration where pending

Fix this by ensuring strict ordering and proper serialization during
teardown:
1. Move ucsi_unregister_partner() to the beginning of the teardown
sequence and protect it under the connector mutex lock.
2. Ensure all pending partner tasks are explicitly flushed and finished
before the workqueue is destroyed.
3. Switch from mod_delayed_work() to a cancel_delayed_work() and
queue_delayed_work() sequence. This guarantees that items currently marked
as pending won't be scheduled an additional time, preventing a double
release of resources which leads to the following crash:

When unpacking host-supplied NTBs, ncm_unwrap_ntb() checks datagram length
against frame_max but does not verify that the datagram fits within the
declared block length. Additionally, when decoding multiple NTBs from a
single socket buffer, subsequent block lengths are not checked against the
actual remaining buffer data.
With these checks missing, a malicious USB host can specify datagram
offsets and lengths that point beyond the block, or supply secondary NTB
headers declaring lengths larger than the buffer. skb_put_data() then
copies adjacent kernel memory from skb_shared_info into the network skb.
Fix this by verifying that sufficient buffer space remains for the NTB
header before parsing, handling zero-length block declarations, ensuring
that block lengths never exceed the remaining buffer space, and verifying
that each datagram payload stays strictly within the block boundary.

The VIA VL805/806 xHCI controller advertises AC64, but fails to handle
DMA addresses at or above 0x1000000000. On systems with large amounts of
RAM, this can cause USB device failures when the controller is given DMA
addresses beyond its usable address width.
Do not use XHCI_NO_64BIT_SUPPORT for this controller. That quirk clears
the cached AC64 capability and limits DMA to 32 bits, causing unnecessary
bouncing for addresses between 4GiB and 64GiB and hiding the controller's
real AC64 capability from code that may need to distinguish register
access width from usable DMA address width.
Track the usable DMA address width separately from the AC64 capability.
Initialize the generic xhci->dma_mask_bits field to 64 and let PCI quirks
reduce it for controllers with narrower DMA support. Set VIA VL805/806 to
36 bits so the DMA API only hands it addresses in the range it can handle
while keeping HCCPARAMS1.AC64 visible.

The f_tcm set_alt() path defers endpoint setup to a work item and
completes the delayed status response from process context. The delayed
work uses f_tcm private state and may complete the setup request after
disconnect or function teardown has already moved on.
Cancel and drain the delayed set_alt work when the function is unbound or
freed. For disable paths, which are reached under the composite device
lock, use a small state machine and a non-sleeping cancellation path
instead of cancel_work_sync(). If the work is already running, mark it
cancelled and let the worker own the cleanup; otherwise tcm_disable() can
cancel the queued work and clean up immediately.
Also serialize the final delayed-status completion with the cancellation
check while holding the composite device lock. This prevents a disconnect
from clearing delayed_status while the worker is about to complete the
control request.

As Dan Carpenter points out, my recent change makes subtle
changes to the error handling that were not intended.
Move the warning print up so it does not get skipped in
case of an error, but handle -EPROBE_DEFER properly now.
Change the devm_gpiod_get() to the _optional variant, which
is in line with the intended behavior and the DT binding,
though this did not work previously.

Previously, pci_pwrctrl_create_devices() was placed in
imx_pcie_host_init(), which is the .init callback of dw_pcie_host_ops.
This callback is invoked not only during probe, but also during resume.
This caused pci_pwrctrl_create_devices() to be called multiple
times across suspend/resume cycles, which is unnecessary since the
pwrctrl devices only need to be created once.
Move pci_pwrctrl_create_devices() to imx_pcie_probe() so that it is only
called once during probe, similar to other regulator_get calls.

allocated pages in _init_ext_path are never freed and sev_init_ex_buffer
is left pointing at the leaked memory in case of any failures during the
function..
Fix by adding an error path that frees the pages and clears
sev_init_ex_buffer. Make sure we only free the memory if the failure
happens before the conversion. Otherwise, we may end up trying to free
up converted pages in case of reclaim failure. rmp_mark_pages_firmware
failures should be rare enough to avoid more code complexity to track
down which pages were reclaimed/leaked vs which are not.

When efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path
returns -ENOSPC without releasing the reference obtained via
kref_get_unless_zero() earlier in the function. All other error paths
correctly drop the reference. This causes a permanent reference leak on the
io_to_abort object.
Additionally, the abort_in_progress flag is left set to true on this path,
which means future abort attempts for the same I/O will immediately return
-EINPROGRESS even though the abort was never submitted, effectively
blocking recovery.
Fix this by adding the missing kref_put() call and reset abort_in_progress
to false, matching the cleanup done in the efct_hw_wq_write() failure path

Drivers which use the scsi_schedule_eh function to run the error handler
currently risk the error handler thread never waking once all commands are
timed out or inactive. There is no enforced memory order between setting
the host into error recovery state and counting busy commands. This can
result in a race with scsi_dec_host_busy where neither CPU sees both
conditions of all commands inactive and the host error state to request
waking the error handler.
To fix this, run the scsi_schedule_eh's scsi_eh_wakeup from a new work item
which will use rcu to ensure scsi_schedule_eh's call to scsi_host_busy will
occur after the error state is globally visible and will be seen by any
current scsi_dec_host_busy callers.

core_scsi3_emulate_pro_register_and_move() maps the PERSISTENT RESERVE OUT
parameter list with transport_kmap_data_sg() and parses the destination
TransportID with target_parse_pr_out_transport_id(). For an iSCSI
TransportID (FORMAT CODE 01b), iscsi_parse_pr_out_transport_id() returns
the ISID in iport_ptr as a raw pointer into that mapped buffer.
The function then unmaps the buffer with transport_kunmap_data_sg() before
dereferencing iport_ptr in strcmp(), __core_scsi3_locate_pr_reg() and
core_scsi3_alloc_registration(). When the parameter list spans more than
one page (PARAMETER LIST LENGTH > 4096), transport_kmap_data_sg() uses
vmap() and transport_kunmap_data_sg() does vunmap(), so the kernel virtual
address backing iport_ptr is torn down and every subsequent dereference is
a use-after-free read of the unmapped region.
Keep the parameter list mapped until iport_ptr is no longer needed: drop
the early transport_kunmap_data_sg() and unmap once on the success path,
right before returning. The error paths already unmap through the existing
"if (buf) transport_kunmap_data_sg(cmd)" at the out: label, which now runs
on every post-map error exit because buf is no longer cleared early. Only
reads of the mapping happen while spinlocks are held; the map and unmap
calls remain outside any lock. The sibling caller
core_scsi3_decode_spec_i_port() already uses the buffer before unmapping it
and is left unchanged.

core_scsi3_decode_spec_i_port() and core_scsi3_emulate_register_and_move()
hand the raw PERSISTENT RESERVE OUT parameter buffer to
target_parse_pr_out_transport_id() without telling it how many bytes are
valid. For an iSCSI TransportID (FORMAT CODE 01b),
iscsi_parse_pr_out_transport_id() locates the ",i,0x" ISID separator with
an unbounded strstr() (and on the error path prints the name with a further
unbounded "%s"). An initiator can submit a TransportID whose iSCSI name
contains neither a ",i,0x" substring nor a NUL terminator, filling the
parameter list to its end, so the scan runs off the end of the buffer.
When the parameter list spans more than one page the buffer is a multi-page
vmap (transport_kmap_data_sg()), so the over-read walks into the trailing
vmalloc guard page and oopses (KASAN: vmalloc-out-of-bounds in strstr). It
is reachable by any fabric that delivers a PR OUT to a device exported
through an iSCSI TPG, including a guest via vhost-scsi.
Pass the number of received bytes down to the parser and validate the iSCSI
TransportID's own self-described length (ADDITIONAL LENGTH + 4) once, up
front: reject it if it is below the spc4r17 minimum or larger than the
received buffer, then bound the separator search, the ISID walk and the
name copy by that length. This is the length check the callers already
perform after the parse (core_scsi3_decode_spec_i_port() compares tid_len
against tpdl, core_scsi3_emulate_register_and_move() validates it against
data_length), moved ahead of the scan. Also drop the unbounded "%s" of the
unterminated name.
Add per-format explicit name-length checks before copying into i_str,
rather than silently truncating with min_t: for FORMAT CODE 00b reject if
the descriptor body (tid_len - 4 bytes) cannot fit in
i_str[TRANSPORT_IQN_LEN]; for FORMAT CODE 01b reject if the name portion
(from &buf[4] up to the separator) cannot fit. Both checks make the bounds
intent explicit at each format branch.
While here, also reject a FORMAT CODE 01b TransportID whose ",i,0x"
separator sits at the very end of the descriptor: that leaves an empty ISID
and points the returned port nexus pointer at buf + tid_len, one past the
descriptor, which the registration code (__core_scsi3_locate_pr_reg(),
__core_scsi3_alloc_registration()) then dereferences as the ISID string --
the same over-read of the parameter buffer for a malformed descriptor.

The 13 comment blocks in dds.h noting which sysfs attribute each
convenience macro creates are opened with the kernel-doc /** marker,
but they are not kernel-doc: there is no identifier to document.
Running kernel-doc on the file emits 103 warnings:
$ scripts/kernel-doc -none drivers/staging/iio/frequency/dds.h
Warning: drivers/staging/iio/frequency/dds.h:10 Cannot find
identifier on line:

The header is not scanned during normal builds (build-time kernel-doc
checks cover .c files), so the warnings only show up when kernel-doc
is invoked on the file directly.
The comments have carried the /** marker since the file was introduced
in commit 4851d97d87c8 ("Staging: IIO: dds.h convenience macros"). The
attributes themselves are already documented in
drivers/staging/iio/Documentation/sysfs-bus-iio-dds, so demote the
comments to plain /* style rather than converting them into kernel-doc

The TPM character devices expose a sequential command/response
interface, but their open handlers leave FMODE_PREAD and FMODE_PWRITE
enabled.
After a command leaves a response pending, pread(fd, buf, 16, 0x1400)
passes 0x1400 as *off to tpm_common_read(). The transfer length is
bounded by response_length, but the offset is used unchecked when
forming data_buffer + *off. A sufficiently large offset therefore causes
an out-of-bounds heap read through copy_to_user() and, if the copy
succeeds, an out-of-bounds zero-write through the following memset().
Positional I/O does not provide coherent semantics for this interface.
An arbitrary pread offset cannot represent how much of a response has
been consumed sequentially. The write callback always stores a command
at the start of data_buffer, while pwrite() does not update file->f_pos
and can leave the sequential read cursor stale.
Call nonseekable_open() from both open handlers. This removes
FMODE_PREAD and FMODE_PWRITE, causing positional reads and writes to
fail with -ESPIPE before reaching the TPM callbacks, and explicitly
marks the files non-seekable. Normal read() and write() continue to use
the existing sequential f_pos cursor, leaving the response state machine
unchanged.
Tested on Linux 6.12 with KASAN and a swtpm TPM2 device:
- sequential partial reads returned the complete response
- pread() and preadv() with offset 0x1400 returned -ESPIPE
- pwrite() and pwritev() with offset zero returned -ESPIPE
- the pending response remained intact after the rejected operations
- a subsequent normal command/response cycle completed normally
- no KASAN report was produced.

Expose the IOC and board temperature sensors of LSI / Broadcom SAS HBAs
through hwmon. Readings come from MPI IO Unit Page 7 via the accessor added
in the preceding patch.
The same fields are exposed by Broadcom's userspace tooling through the
/dev/mpt[23]ctl ioctl path (typically root-only): IOCTemperature and
BoardTemperature in lsiutil; ROC and Controller in storcli. With this
driver, sensors(1) shows them unprivileged:
$ sensors mpt3sas-pci-0200
mpt3sas-pci-0200
Adapter: PCI adapter
IOC: +42.0°C
Each channel is gated independently by its *TemperatureUnits field through
is_visible(); cards that populate only one sensor expose only one input
file, and cards that populate neither do not register an hwmon device.
The hwmon code is gated directly on CONFIG_HWMON. IS_REACHABLE() is used
rather than IS_ENABLED() so that SCSI_MPT3SAS=y with HWMON=m still builds;
in that configuration, the sensors are not exposed (same pattern as i915
and xe).
