commit b3d4f7f2288901ed2392695919b3c0e24c1b4084 upstream.
The 1st and 2nd expansion BAR configuration registers are configured,
when the driver starts up, in variables 'barcfg_msix_general' and
'barcfg_msix_xpb', respectively. The 'LengthSelect' field is ORed in
from bit 0, which is incorrect. The 'LengthSelect' field should
start from bit 27.
This has largely gone un-noticed because
NFP_PCIE_BAR_PCIE2CPP_LengthSelect_32BIT happens to be 0.

never sleepbeing called in atomic context.

commit 93cd256ab224c2519e7c4e5f58bb4f1ac2bf0965 upstream.
Some people are seeing a warning similar to this when using a crystal:
max310x 11-006c: clock is not stable yet
The datasheet doesn't mention the maximum time to wait for the clock to be
stable when using a crystal, and it seems that the 10ms delay in the driver
is not always sufficient.
Jan Kundrát reported that it took three tries (each separated by 10ms) to
get a stable clock.
Modify behavior to check stable clock ready bit multiple times (20), and
waiting 10ms between each try.
Note: the first draft of the driver originally used a 50ms delay, without
checking the clock stable bit.
Then a loop with 1000 retries was implemented, each time reading the clock
stable bit.

commit e0526ec5360a48ad3ab2e26e802b0532302a7e11 upstream.
In commit ac5047671758 ("hv_netvsc: Disable NAPI before closing the
VMBus channel"), napi_disable was getting called for all channels,
including all subchannels without confirming if they are enabled or not.
This caused hv_netvsc getting hung at napi_disable, when netvsc_probe()
has finished running but nvdev->subchan_work has not started yet.
netvsc_subchan_work() -> rndis_set_subchannel() has not created the
sub-channels and because of that netvsc_sc_open() is not running.
netvsc_remove() calls cancel_work_sync(&nvdev->subchan_work), for which
netvsc_subchan_work did not run.
netif_napi_add() sets the bit NAPI_STATE_SCHED because it ensures NAPI
cannot be scheduled. Then netvsc_sc_open() -> napi_enable will clear the
NAPIF_STATE_SCHED bit, so it can be scheduled. napi_disable() does the
opposite.
Now during netvsc_device_remove(), when napi_disable is called for those
subchannels, napi_disable gets stuck on infinite msleep.
This fix addresses this problem by ensuring that napi_disable() is not
getting called for non-enabled NAPI struct.
But netif_napi_del() is still necessary for these non-enabled NAPI struct
for cleanup purpose.

Commit 4c3577db3e4f ("Staging: iio: impedance-analyzer: Fix sparse

in one of the two 16 bit IIO channels always being zero (when both are
enabled).
This is because int is 32 bits wide on most architectures and in the
case of a little-endian machine the two most significant bytes would
occupy the buffer for the second channel as 'val' is being passed as a
void pointer to 'iio_push_to_buffers()'.
Fix by defining 'val' as u16. Tested working on ARM64.

In (e)poll mode, threads often depend on I/O events to determine when
data is ready for consumption. Within binder, a thread may initiate a
command via BINDER_WRITE_READ without a read buffer and then make use
of epoll_wait() or similar to consume any responses afterwards.
It is then crucial that epoll threads are signaled via wakeup when they
queue their own work. Otherwise, they risk waiting indefinitely for an
event leaving their work unhandled. What is worse, subsequent commands
won't trigger a wakeup either as the thread has pending work.

commit 7b55984c96ffe9e236eb9c82a2196e0b1f84990d upstream.
Invoking the make_tx_response() / push_tx_responses() pair with no lock
held would be acceptable only if all such invocations happened from the
same context (NAPI instance or dealloc thread). Since this isn't the
case, and since the interface "spec" also doesn't demand that multicast
operations may only be performed with no in-flight transmits,
MCAST_{ADD,DEL} processing also needs to acquire the response lock
around the invocations.
To prevent similar mistakes going forward, "downgrade" the present
functions to private helpers of just the two remaining ones using them
directly, with no forward declarations anymore. This involves renaming
what so far was make_tx_response(), for the new function of that name
to serve the new (wrapper) purpose.
While there,
- constify the txp parameters,
- correct xenvif_idx_release()'s status parameter's type,
- rename {,_}make_tx_response()'s status parameters for consistency with
xenvif_idx_release()'s.

According to the spec this feature may be used based only the following
three conditions:
6.5.3 a_alt_hnp_support
Setting this feature indicates to the B-device that it is connected to
an A-device port that is not capable of HNP, but that the A-device does
have an alternate port that is capable of HNP.
The A-device is required to set this feature under the following conditions:
• the A-device has multiple receptacles
• the A-device port that connects to the B-device does not support HNP
• the A-device has another port that does support HNP

possible that CCI still reports the previous completion. The
UCSI spec is aware of this and provides two completion bits in

alternate the notification handler can determine if the completion
bit is from the current command.
The initial UCSI code correctly handled this but the distinction
between the two completion bits was lost with the introduction of
the new API.

commit c1d6708bf0d3dd976460d435373cf5abf21ce258 upstream.
If a input device is opened before hid_hw_start is called, events may
not be received from the hardware. In the case of USB-backed devices,
for example, the hid_hw_start function is responsible for filling in
the URB which is submitted when the input device is opened. If a device
is opened prematurely, polling will never start because the device will
not have been in the correct state to send the URB.
Because the wacom driver registers its input devices before calling
hid_hw_start, there is a window of time where a device can be opened
and end up in an inoperable state. Some ARM-based Chromebooks in particular
reliably trigger this bug.
This commit splits the wacom_register_inputs function into two pieces.
One which is responsible for setting up the allocated inputs (and runs
prior to hid_hw_start so that devices are ready for any input events
they may end up receiving) and another which only registers the devices
(and runs after hid_hw_start to ensure devices can be immediately opened
without issue). Note that the functions to initialize the LEDs and remotes
are also moved after hid_hw_start to maintain their own dependency chains.

The xf86-input-wacom driver does not treat '0' as a valid serial
number and will drop any input report which contains an
MSC_SERIAL = 0 event. The kernel driver already takes care to
avoid sending any MSC_SERIAL event if the value of serial[0] == 0
(which is the case for devices that don't actually report a
serial number), but this is not quite sufficient.
Only the lower 32 bits of the serial get reported to userspace,
so if this portion of the serial is zero then there can still
be problems.
This commit allows the driver to report either the lower 32 bits
if they are non-zero or the upper 32 bits otherwise.

Replace affected kref_read calls with a macro that reads the

commit 1692b9775e745f84b69dc8ad0075b0855a43db4e upstream.
The cited commit introduces and uses the string constants dpp_tx_err and
dpp_rx_err. These are assigned to constant fields of the array
dwxgmac3_error_desc.
It has been reported that on GCC 6 and 7.5.0 this results in warnings
such as:
.../dwxgmac2_core.c:836:20: error: initialiser element is not constant
{ true, "TDPES0", dpp_tx_err },
I have been able to reproduce this using: GCC 7.5.0, 8.4.0, 9.4.0 and 10.5.0.
But not GCC 13.2.0.
So it seems this effects older compilers but not newer ones.
As Jon points out in his report, the minimum compiler supported by
the kernel is GCC 5.1, so it does seem that this ought to be fixed.
It is not clear to me what combination of 'const', if any, would address
this problem. So this patch takes of using #defines for the string
constants
Compile tested only.

After commit 936e4d49ecbc ("Input: atkbd - skip ATKBD_CMD_GETID in
translated mode") the keyboard on Dell XPS 13 9350 / 9360 / 9370 models
has stopped working after a suspend/resume.
The problem appears to be that atkbd_probe() fails when called
from atkbd_reconnect() on resume, which on systems where
ATKBD_CMD_GETID is skipped can only happen by ATKBD_CMD_SETLEDS
failing. ATKBD_CMD_SETLEDS failing because ATKBD_CMD_GETID was
skipped is weird, but apparently that is what is happening.
Fix this by also skipping ATKBD_CMD_SETLEDS when skipping
ATKBD_CMD_GETID.

commit a60e6c3918d20848906ffcdfcf72ca6a8cfbcf2e upstream.
When closing the laptop lid with an external screen connected, the mouse
pointer has a constant movement to the lower right corner. Opening the
lid again stops this movement, but after that the touchpad does no longer
register clicks.
The touchpad is connected both via i2c-hid and PS/2, the predecessor of
this device (NS70MU) has the same layout in this regard and also strange
behaviour caused by the psmouse and the i2c-hid driver fighting over
touchpad control. This fix is reusing the same workaround by just
disabling the PS/2 aux port, that is only used by the touchpad, to give the
i2c-hid driver the lone control over the touchpad.

Commit 4373534a9850 ("scsi: core: Move scsi_host_busy() out of host lock

EH. The core idea was to move scsi_host_busy() out of the host lock when
processing individual commands for EH. However, a suggested style change
inadvertently caused scsi_host_busy() to remain under the host lock. Fix
this by calling scsi_host_busy() outside the lock.

Before commit 7108b80a542b ("hwmon/coretemp: Handle large core ID
value"), there is a fixed mapping between
1. cpu_core_id
2. the index in pdata->core_data[] array
3. the sysfs attr name, aka "tempX_"
The later two always equal cpu_core_id + 2.
After the commit, pdata->core_data[] index is got from ida so that it
can handle sparse core ids and support more cores within a package.
However, the commit erroneously maps the sysfs attr name to
pdata->core_data[] index instead of cpu_core_id + 2.
As a result, the code is not aligned with the comments, and brings user
visible changes in hwmon sysfs on systems with sparse core id.
For example, before commit 7108b80a542b ("hwmon/coretemp: Handle large
core ID value"),
/sys/class/hwmon/hwmon2/temp2_label:Core 0
/sys/class/hwmon/hwmon2/temp3_label:Core 1
/sys/class/hwmon/hwmon2/temp4_label:Core 2
/sys/class/hwmon/hwmon2/temp5_label:Core 3
/sys/class/hwmon/hwmon2/temp6_label:Core 4
/sys/class/hwmon/hwmon3/temp10_label:Core 8
/sys/class/hwmon/hwmon3/temp11_label:Core 9
after commit,
/sys/class/hwmon/hwmon2/temp2_label:Core 0
/sys/class/hwmon/hwmon2/temp3_label:Core 1
/sys/class/hwmon/hwmon2/temp4_label:Core 2
/sys/class/hwmon/hwmon2/temp5_label:Core 3
/sys/class/hwmon/hwmon2/temp6_label:Core 4
/sys/class/hwmon/hwmon2/temp7_label:Core 8

[ Upstream commit 4373534a9850627a2695317944898eb1283a2db0 ]
Inside scsi_eh_wakeup(), scsi_host_busy() is called & checked with host
lock every time for deciding if error handler kthread needs to be waken up.
This can be too heavy in case of recovery, such as:
- N hardware queues
- queue depth is M for each hardware queue
- each scsi_host_busy() iterates over (N * M) tag/requests
If recovery is triggered in case that all requests are in-flight, each
scsi_eh_wakeup() is strictly serialized, when scsi_eh_wakeup() is called
for the last in-flight request, scsi_host_busy() has been run for (N * M -
1) times, and request has been iterated for (N*M - 1) * (N * M) times.
If both N and M are big enough, hard lockup can be triggered on acquiring
host lock, and it is observed on mpi3mr(128 hw queues, queue depth 8169).
Fix the issue by calling scsi_host_busy() outside the host lock. We don't
need the host lock for getting busy count because host the lock never
covers that.

[ Upstream commit 1291b716bbf969e101d517bfb8ba18d958f758b8 ]
When a device with AER detects an error, it logs error information in its
own AER Error Status registers. It may send an Error Message to the Root
Port (RCEC in the case of an RCiEP), which logs the fact that an Error
Message was received (Root Error Status) and the Requester ID of the
message source (Error Source Identification).
aer_print_port_info() prints the Requester ID from the Root Port Error
Source in the usual Linux "bb:dd.f" format, but when find_source_device()
finds no error details in the hierarchy below the Root Port, it printed the
raw Requester ID without decoding it.
Decode the Requester ID in the usual Linux format so it matches other
messages.
Sample message changes:
- pcieport 0000:00:1c.5: AER: Correctable error received: 0000:00:1c.5
- pcieport 0000:00:1c.5: AER: can't find device of ID00e5
+ pcieport 0000:00:1c.5: AER: Correctable error message received from 0000:00:1c.5
+ pcieport 0000:00:1c.5: AER: found no error details for 0000:00:1c.5

The capability CAP_CHECKPOINT_RESTORE was introduced to allow non-root
users to checkpoint and restore processes as non-root with CRIU.
This change extends CAP_CHECKPOINT_RESTORE to enable the CRIU option
'--shell-job' as non-root. CRIU's man-page describes the '--shell-job'
option like this:
Allow one to dump shell jobs. This implies the restored task will
inherit session and process group ID from the criu itself. This option
also allows to migrate a single external tty connection, to migrate
applications like top.
TIOCSLCKTRMIOS can only be done if the process has CAP_SYS_ADMIN and
this change extends it to CAP_SYS_ADMIN or CAP_CHECKPOINT_RESTORE.
With this change it is possible to checkpoint and restore processes
which have a tty connection as non-root if CAP_CHECKPOINT_RESTORE is
set.

A PCI device hot removal may occur while stdev->cdev is held open. The call
to stdev_release() then happens during close or exit, at a point way past
switchtec_pci_remove(). Otherwise the last ref would vanish with the
trailing put_device(), just before return.
At that later point in time, the devm cleanup has already removed the
stdev->mmio_mrpc mapping. Also, the stdev->pdev reference was not a counted
one. Therefore, in DMA mode, the iowrite32() in stdev_release() will cause
a fatal page fault, and the subsequent dma_free_coherent(), if reached,
would pass a stale &stdev->pdev->dev pointer.
Fix by moving MRPC DMA shutdown into switchtec_pci_remove(), after
stdev_kill(). Counting the stdev->pdev ref is now optional, but may prevent
future accidents.

WDTCTRL bit 3 sets the mode choice for the clock input of IT8784/IT8786.
Some motherboards require this bit to be set to 1 (= PCICLK mode),
otherwise the watchdog functionality gets broken. The BIOS of those
motherboards sets WDTCTRL bit 3 already to 1.
Instead of setting all bits of WDTCTRL to 0 by writing 0x00 to it, keep
bit 3 of it unchanged for IT8784/IT8786 chips. In this way, bit 3 keeps
the status as set by the BIOS of the motherboard.

| spin_unlock_irqrestore(&priv->lock, flags)

| ipoib_mcast_remove_list(&remove_list)
(Here, `mcast` is no longer on the | list_for_each_entry_safe(mcast, tmcast,

spinning on the `remove_list` of | >>> wait_for_completion(&mcast->done)
the other thread which is blocked |
and the list is still valid on |
it's stack.)
Fix this by keeping the lock held and changing to GFP_ATOMIC to prevent
eventual sleeps.
Unfortunately we could not reproduce the lockup and confirm this fix but
based on the code review I think this fix should address such lockups.

[ Upstream commit 16ac5b21b31b439f03cdf44c153c5f5af94fb3eb ]
Based on grepping through the source code this driver appears to be
missing a call to drm_atomic_helper_shutdown() at system shutdown time
and at driver unbind time. Among other things, this means that if a
panel is in use that it won't be cleanly powered off at system
shutdown time.
The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart and at driver remove (or unbind) time comes
straight out of the kernel doc "driver instance overview" in
drm_drv.c.
A few notes about this fix:
- When adding drm_atomic_helper_shutdown() to the unbind path, I added
it after drm_kms_helper_poll_fini() since that's when other drivers
seemed to have it.
- Technically with a previous patch, ("drm/atomic-helper:
drm_atomic_helper_shutdown(NULL) should be a noop"), we don't
actually need to check to see if our "drm" pointer is NULL before
calling drm_atomic_helper_shutdown(). We'll leave the "if" test in,
though, so that this patch can land without any dependencies. It
could potentially be removed later.
- This patch also makes sure to set the drvdata to NULL in the case of
bind errors to make sure that shutdown can't access freed data.

When using 32 bit RGB formats, the RGA on the rk3568 produces wrong
colors as the wrong color channels are read or written. The reason is
that the format description for the channel swizzeling is wrong and the
wrong bits are configured. For example, when converting ARGB32 to NV12,
the alpha channel is used as blue channel.. This doesn't happen if the
color format is the same on both sides.
Fix the color_swap settings of the formats to correctly handle 32 bit
RGB formats.
For RGA_COLOR_FMT_XBGR8888, the RGA_COLOR_ALPHA_SWAP bit doesn't have an
effect. Thus, it isn't possible to handle the V4L2_PIX_FMT_XRGB32. Thus,
it is removed from the list of supported formats.

It's been reported that DSI host driver's detach can be called without
the attach ever happening:
https://lore.kernel.org/all/20230412073954.20601-1-tony@atomide.com/
After reading the code, I think this is what happens:
We have a DSI host defined in the device tree and a DSI peripheral under
that host (i.e. an i2c device using the DSI as data bus doesn't exhibit
this behavior).
The host driver calls mipi_dsi_host_register(), which causes (via a few
functions) mipi_dsi_device_add() to be called for the DSI peripheral. So
now we have a DSI device under the host, but attach hasn't been called.
Normally the probing of the devices continues, and eventually the DSI
peripheral's driver will call mipi_dsi_attach(), attaching the
peripheral.
However, if the host driver's probe encounters an error after calling
mipi_dsi_host_register(), and before the peripheral has called
mipi_dsi_attach(), the host driver will do cleanups and return an error
from its probe function. The cleanups include calling
mipi_dsi_host_unregister().
mipi_dsi_host_unregister() will call two functions for all its DSI
peripheral devices: mipi_dsi_detach() and mipi_dsi_device_unregister().
The latter makes sense, as the device exists, but the former may be
wrong as attach has not necessarily been done.
To fix this, track the attached state of the peripheral, and only detach
from mipi_dsi_host_unregister() if the peripheral was attached.
Note that I have only tested this with a board with an i2c DSI
peripheral, not with a "pure" DSI peripheral.
However, slightly related, the unregister machinery still seems broken.
E.g. if the DSI host driver is unbound, it'll detach and unregister the
DSI peripherals. After that, when the DSI peripheral driver unbound
it'll call detach either directly or using the devm variant, leading to
a crash. And probably the driver will crash if it happens, for some
reason, to try to send a message via the DSI bus.
But that's another topic.

The current FC error recovery is sending up to three REC (recovery) frames
in 10 second intervals, and as a final step sending an ABTS after 30
seconds for the command itself. Unfortunately sending an ABTS is also the
action for the SCSI abort handler, and the default timeout for SCSI
commands is also 30 seconds. This causes two ABTS to be scheduled, with the
libfc one slightly earlier. The ABTS scheduled by SCSI EH then sees the
command to be already aborted, and will always return with a 'GOOD' status
irrespective on the actual result from the first ABTS. This causes the
SCSI EH abort handler to always succeed, and SCSI EH never to be engaged.
Fix this by not issuing an ABTS when a SCSI command is present for the
exchange, but rather wait for the abort scheduled from SCSI EH. And warn
if an abort is already scheduled to avoid similar errors in the future.

Use list_first_entry_or_null instead of list_first_entry to retrieve

The function list_first_entry always return a non NULL pointer even if
the list is empty. Hence checking if the pointer returned is NULL does
not tell if the list is empty or not.

[ Upstream commit a70297d2213253853e95f5b49651f924990c6d3b ]
There are two major types of uncorrected recoverable (UCR) errors :
- Synchronous error: The error is detected and raised at the point of
the consumption in the execution flow, e.g. when a CPU tries to
access a poisoned cache line. The CPU will take a synchronous error
exception such as Synchronous External Abort (SEA) on Arm64 and
Machine Check Exception (MCE) on X86. OS requires to take action (for
example, offline failure page/kill failure thread) to recover this
uncorrectable error.
- Asynchronous error: The error is detected out of processor execution
context, e.g. when an error is detected by a background scrubber.
Some data in the memory are corrupted. But the data have not been
consumed. OS is optional to take action to recover this uncorrectable
error.
When APEI firmware first is enabled, a platform may describe one error
source for the handling of synchronous errors (e.g. MCE or SEA notification
), or for handling asynchronous errors (e.g. SCI or External Interrupt
notification). In other words, we can distinguish synchronous errors by
APEI notification. For synchronous errors, kernel will kill the current
process which accessing the poisoned page by sending SIGBUS with
BUS_MCEERR_AR. In addition, for asynchronous errors, kernel will notify the
process who owns the poisoned page by sending SIGBUS with BUS_MCEERR_AO in
early kill mode. However, the GHES driver always sets mf_flags to 0 so that
all synchronous errors are handled as asynchronous errors in memory failure.
To this end, set memory failure flags as MF_ACTION_REQUIRED on synchronous
events.

According to the comments in include/linux/fortify-string.h, 'memcpy()',
'memmove()' and 'memset()' must not be used beyond individual struct
members to ensure that the compiler can enforce protection against
buffer overflows, and, IIUC, this also applies to partial copies from
the particular member ('vendor->byte_data' in this case). So it should
be better (and safer) to do both copies at once (and 'byte_data' of
'struct acpi_resource_vendor_typed' seems to be a good candidate for
'__counted_by(byte_length)' as well).

The use_count of a regulator should only be incremented when the
enable_count changes from 0 to 1. Similarly, the use_count should
only be decremented when the enable_count changes from 1 to 0.
In the previous implementation, use_count was sometimes decremented
to 0 when some consumer called unbalanced disable,
leading to unexpected disable even the regulator is enabled by
other consumers. With this change, the use_count accurately reflects
the number of users which the regulator is enabled.
This should make things more robust in the case where a consumer does
leak references.

In mtk_jpeg_dec_device_run, if error happens in

mark the job as finished by invoking v4l2_m2m_job_finish.
There are two methods to trigger the bug. If we remove the

The possible sequence is as follows, which will cause a
use-after-free bug.
CPU0 CPU1
mtk_jpeg_dec_... |

If we close the file descriptor, which will call mtk_jpeg_release,
it will have a similar sequence.
Fix this bug by starting timeout worker only if started jpegdec worker
successfully. Then v4l2_m2m_job_finish will only be called in

commit 95d4b471953411854f9c80b568da7fcf753f3801 upstream.
tidss_crtc_atomic_flush() checks if the crtc is enabled, and if not,
returns immediately as there's no reason to do any register changes.
However, the code checks for 'crtc->state->enable', which does not
reflect the actual HW state. We should instead look at the
'crtc->state->active' flag.
This causes the tidss_crtc_atomic_flush() to proceed with the flush even
if the active state is false, which then causes us to hit the
WARN_ON(!crtc->state->event) check.
Fix this by checking the active flag, and while at it, fix the related
debug print which had "active" and "needs modeset" wrong way.

commit cb4daf271302d71a6b9a7c01bd0b6d76febd8f0c upstream.
If we get a deadlock after the fb lookup in drm_mode_page_flip_ioctl()
we proceed to unref the fb and then retry the whole thing from the top.
But we forget to reset the fb pointer back to NULL, and so if we then
get another error during the retry, before the fb lookup, we proceed
the unref the same fb again without having gotten another reference.
The end result is that the fb will (eventually) end up being freed
while it's still in use.
Reset fb to NULL once we've unreffed it to avoid doing it again
until we've done another fb lookup.
This turned out to be pretty easy to hit on a DG2 when doing async
flips (and CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y). The first symptom I
saw that drm_closefb() simply got stuck in a busy loop while walking
the framebuffer list. Fortunately I was able to convince it to oops
instead, and from there it was easier to track down the culprit.

The running list is supposed to contain requests that are pinning the
exclusive lock, i.e. those that must be flushed before exclusive lock
is released. When wake_lock_waiters() is called to handle an error,
requests on the acquiring list are failed with that error and no
flushing takes place. Briefly moving them to the running list is not
only pointless but also harmful: if exclusive lock gets acquired
before all of their state machines are scheduled and go through
rbd_lock_del_request(), we trigger
rbd_assert(list_empty(&rbd_dev->running_list));

commit 84a6be7db9050dd2601c9870f65eab9a665d2d5d upstream.
There is no need to duplicate what SPI core or individual controller
drivers already do, i.e. mapping the buffers for DMA capable transfers.
Note, that the code, besides its redundancy, was buggy: strictly speaking
there is no guarantee, while it's true for those which can use this code
(see below), that the SPI host controller _is_ the device which does DMA.
Also see the Link tags below.
Additional notes. Currently only two SPI host controller drivers may use
premapped (by the user) DMA buffers:
- drivers/spi/spi-au1550.c
- drivers/spi/spi-fsl-spi.c
Both of them have DMA mapping support code. I don't expect that SPI host
controller code is worse than what has been done in mmc_spi. Hence I do
not expect any regressions here. Otherwise, I'm pretty much sure these
regressions have to be fixed in the respective drivers, and not here.
That said, remove all related pieces of DMA mapping code from mmc_spi.

commit 4d0c8d0aef6355660b6775d57ccd5d4ea2e15802 upstream.
Field Firmware Update (ffu) may use close-ended or open ended sequence.
Each such sequence is comprised of a write commands enclosed between 2
switch commands - to and from ffu mode. So for the close-ended case, it
will be: cmd6->cmd23-cmd25-cmd6.
Some host controllers however, get confused when multi-block rw is sent
without sbc, and may generate auto-cmd12 which breaks the ffu sequence.
I encountered this issue while testing fwupd (github.com/fwupd/fwupd)
on HP Chromebook x2, a qualcomm based QC-7c, code name - strongbad.
Instead of a quirk, or hooking the request function of the msm ops,
it would be better to fix the ioctl handling and make it use mrq.sbc
instead of issuing SET_BLOCK_COUNT separately.

Ensure read and write locks for the channel are not taken in succession by
dropping the read lock from parse_xfer_event() such that a callback given
to client can potentially queue buffers and acquire the write lock in that
process. Any queueing of buffers should be done without channel read lock
acquired as it can result in multiple locks and a soft lockup.

When dma_async_device_unregister() is called (because of managed API or

unregistered, leading to this NULL pointer:

Look at dma_async_device_register() function error path, channel device
unregistration is done only if chan->local is not NULL.
Then add the same condition at the beginning of

The ADC needs a voltage reference to work correctly.
Users can provide an external voltage reference or use the chip internal
reference to operate the ADC.
The availability of an in chip reference for the ADC saves the user from
having to supply an external voltage reference, which makes the external
reference an optional property as described in the device tree
documentation.
Though, to use the internal reference, it must be enabled by writing to
the configuration register.

AD7091R-5 devices are supported by the ad7091r-5 driver together with
the ad7091r-base driver. Those drivers declared iio events for notifying
user space when ADC readings fall bellow the thresholds of low limit
registers or above the values set in high limit registers.
However, to configure iio events and their thresholds, a set of callback
functions must be implemented and those were not present until now.
The consequence of trying to configure ad7091r-5 events without the
proper callback functions was a null pointer dereference in the kernel
because the pointers to the callback functions were not set.
Implement event configuration callbacks allowing users to read/write
event thresholds and enable/disable event generation.
Since the event spec structs are generic to AD7091R devices, also move
those from the ad7091r-5 driver the base driver so they can be reused
when support for ad7091r-2/-4/-8 be added.

The original comment is confusing because it implies that variants other
than the SC16IS762 supports other SPI modes beside SPI_MODE_0.
Extract from datasheet:
The SC16IS762 differs from the SC16IS752 in that it supports SPI clock
speeds up to 15 Mbit/s instead of the 4 Mbit/s supported by the
SC16IS752... In all other aspects, the SC16IS762 is functionally and
electrically the same as the SC16IS752.
The same is also true of the SC16IS760 variant versus the SC16IS740 and
SC16IS750 variants.
For all variants, only SPI mode 0 is supported.
Change comment and abort probing if the specified SPI mode is not
SPI_MODE_0.

To properly handle ACK on the bus when transferring more than one
message in polling mode, move the polling handling loop from
s3c24xx_i2c_message_start() to s3c24xx_i2c_doxfer(). This way
i2c_s3c_irq_nextbyte() is always executed till the end, properly
acknowledging the IRQ bits and no recursive calls to
i2c_s3c_irq_nextbyte() are made.
While touching this, also fix finishing transfers in polling mode by
using common code path and always waiting for the bus to become idle
and disabled.

[ Upstream commit 483ae90d8f976f8339cf81066312e1329f2d3706 ]
When tc filters are first added to a net device, the corresponding local
port gets bound to an ACL group in the device. The group contains a list
of ACLs. In turn, each ACL points to a different TCAM region where the
filters are stored. During forwarding, the ACLs are sequentially
evaluated until a match is found.
One reason to place filters in different regions is when they are added
with decreasing priorities and in an alternating order so that two
consecutive filters can never fit in the same region because of their
key usage.
In Spectrum-2 and newer ASICs the firmware started to report that the
maximum number of ACLs in a group is more than 16, but the layout of the
register that configures ACL groups (PAGT) was not updated to account
for that. It is therefore possible to hit stack corruption [1] in the
rare case where more than 16 ACLs in a group are required.
Fix by limiting the maximum ACL group size to the minimum between what
the firmware reports and the maximum ACLs that fit in the PAGT register.
Add a test case to make sure the machine does not crash when this
condition is hit.

[ Upstream commit 6d6eeabcfaba2fcadf5443b575789ea606f9de83 ]
Lately, a bug was found when many TC filters are added - at some point,
several bugs are printed to dmesg [1] and the switch is crashed with
segmentation fault.
The issue starts when gen_pool_free() fails because of unexpected
behavior - a try to free memory which is already freed, this leads to BUG()
call which crashes the switch and makes many other bugs.
Trying to track down the unexpected behavior led to a bug in eRP code. The
function mlxsw_sp_acl_erp_table_alloc() gets a pointer to the allocated
index, sets the value and returns an error code. When gen_pool_alloc()
fails it returns address 0, we track it and return -ENOBUFS outside, BUT
the call for gen_pool_alloc() already override the index in erp_table
structure. This is a problem when such allocation is done as part of
table expansion. This is not a new table, which will not be used in case
of allocation failure. We try to expand eRP table and override the
current index (non-zero) with zero. Then, it leads to an unexpected
behavior when address 0 is freed twice. Note that address 0 is valid in
erp_table->base_index and indeed other tables use it.
gen_pool_alloc() fails in case that there is no space left in the
pre-allocated pool, in our case, the pool is limited to
ACL_MAX_ERPT_BANK_SIZE, which is read from hardware. When more than max
erp entries are required, we exceed the limit and return an error, this
error leads to "Failed to migrate vregion" print.
Fix this by changing erp_table->base_index only in case of a successful
allocation.
Add a test case for such a scenario. Without this fix it causes
segmentation fault:

In ravb_start_xmit(), ravb driver uses u32 variable to store result of
dma_map_single() call. Since ravb hardware has 32-bit address fields in
descriptors, this works properly when mapping is successful - it is
platform's job to provide mapping addresses that fit into hardware
limitations.
However, in failure case dma_map_single() returns DMA_MAPPING_ERROR
constant that is 64-bit when dma_addr_t is 64-bit. Storing this constant
in u32 leads to truncation, and further call to dma_mapping_error()
fails to notice the error.
Fix that by storing result of dma_map_single() in a dma_addr_t
variable.

[ Upstream commit e398822c4751017fe401f57409488f5948d12fb5 ]
The RZ/G3S SMARC Module has 2 KSZ9131 PHYs. In this setup, the KSZ9131 PHY
is used with the ravb Ethernet driver. It has been discovered that when
bringing the Ethernet interface down/up continuously, e.g., with the
following sh script:
$ while :; do ifconfig eth0 down; ifconfig eth0 up; done
the link speed and duplex are wrong after interrupting the bring down/up
operation even though the Ethernet interface is up. To recover from this
state the following configuration sequence is necessary (executed
manually):
$ ifconfig eth0 down
$ ifconfig eth0 up
The behavior has been identified also on the Microchip SAMA7G5-EK board
which runs the macb driver and uses the same PHY.
The order of PHY-related operations in ravb_open() is as follows:
ravb_open() ->
ravb_phy_start() ->
ravb_phy_init() ->
of_phy_connect() ->
phy_connect_direct() ->
phy_attach_direct() ->
phy_init_hw() ->
phydev->drv->soft_reset()
phydev->drv->config_init()
phydev->drv->config_intr()
phy_resume()
kszphy_resume()
The order of PHY-related operations in ravb_close is as follows:
ravb_close() ->
phy_stop() ->
phy_suspend() ->
kszphy_suspend() ->
genphy_suspend()
// set BMCR_PDOWN bit in MII_BMCR
In genphy_suspend() setting the BMCR_PDWN bit in MII_BMCR switches the PHY
to Software Power-Down (SPD) mode (according to the KSZ9131 datasheet).
Thus, when opening the interface after it has been previously closed (via
ravb_close()), the phydev->drv->config_init() and
phydev->drv->config_intr() reach the KSZ9131 PHY driver via the
ksz9131_config_init() and kszphy_config_intr() functions.
KSZ9131 specifies that the MII management interface remains operational
during SPD (Software Power-Down), but (according to manual):
- Only access to the standard registers (0 through 31) is supported.
- Access to MMD address spaces other than MMD address space 1 is possible
if the spd_clock_gate_override bit is set.
- Access to MMD address space 1 is not possible.
The spd_clock_gate_override bit is not used in the KSZ9131 driver.
ksz9131_config_init() configures RGMII delay, pad skews and LEDs by
accessesing MMD registers other than those in address space 1.
The datasheet for the KSZ9131 does not specify what happens if registers
from an unsupported address space are accessed while the PHY is in SPD.
To fix the issue the .soft_reset method has been instantiated for KSZ9131,
too. This resets the PHY to the default state before doing any
configurations to it, thus switching it out of SPD.

of a received frame. This value is written to the register
AM65_CPSW_PORT_REG_RX_MAXLEN.
The maximum MTU configured on the network device should then leave
some room for the ethernet headers and frame check. Otherwise, if
the network interface is configured to its maximum mtu possible,
the frames will be larger than AM65_CPSW_MAX_PACKET_SIZE and will
get dropped as oversized.
The switch supports ethernet frame sizes between 64 and 2024 bytes

The PCI driver invokes the PHY APIs using the ks_pcie_enable_phy()
function. The PHY in this case is the Serdes. It is possible that the
PCI instance is configured for two lane operation across two different
Serdes instances, using one lane of each Serdes.
In such a configuration, if the reference clock for one Serdes is
provided by the other Serdes, it results in a race condition. After the
Serdes providing the reference clock is initialized by the PCI driver by
invoking its PHY APIs, it is not guaranteed that this Serdes remains
powered on long enough for the PHY APIs based initialization of the
dependent Serdes. In such cases, the PLL of the dependent Serdes fails
to lock due to the absence of the reference clock from the former Serdes
which has been powered off by the PM Core.
Fix this by obtaining reference to the PHYs before invoking the PHY
initialization APIs and releasing reference after the initialization is
complete.

In ACM support for sending breaks to devices is optional.
If a device says that it doenot support sending breaks,
the host must respect that.
Given the number of optional features providing tty operations
for each combination is not practical and errors need to be

In case a device does not support break, we want the tty layer
to treat that like it treats drivers that statically cannot

The reset gpio was being handled with inverted polarity. This means that
as far as gpiolib is concerned we were actually leaving the pin asserted
(in theory, this would mean reset). However, inverting the polarity in
devicetree made things work. Fix it by doing it the proper way and how
gpiolib expects it to be done.
While at it, moved the handling to it's own function and dropped
'reset_gpio' from the 'struct ad9467_state' as we only need it during
probe. On top of that, refactored things so that we now request the gpio
asserted (i.e in reset) and then de-assert it. Also note that we now use
gpiod_set_value_cansleep() instead of gpiod_direction_output() as we
already request the pin as output.

[ Upstream commit 78d60dae9a0c9f09aa3d6477c94047df2fe6f7b0 ]
When using the serial port as RS485 port, the tx statemachine is used to
control the RTS pin to drive the RS485 transceiver TX_EN pin. When the
TTY port is closed in the middle of a transmission (for instance during
userland application crash), imx_uart_shutdown disables the interface
and disables the Transmission Complete interrupt. afer that,
imx_uart_stop_tx bails on an incomplete transmission, to be retriggered
by the TC interrupt. This interrupt is disabled and therefore the tx
statemachine never transitions out of SEND. The statemachine is in
deadlock now, and the TX_EN remains low, making the interface useless.
imx_uart_stop_tx now checks for incomplete transmission AND whether TC
interrupts are enabled before bailing to be retriggered. This makes sure
the state machine handling is reached, and is properly set to
WAIT_AFTER_SEND.

commit 502296030ec6b0329e00f9fb15018e170cc63037 upstream.
There appear to be a few different ways that Wacom devices can deal with
confidence:
1. If the device looses confidence in a touch, it will first clear
the tipswitch flag in one report, and then clear the confidence
flag in a second report. This behavior is used by e.g. DTH-2452.
2. If the device looses confidence in a touch, it will clear both
the tipswitch and confidence flags within the same report. This
behavior is used by some AES devices.
3. If the device looses confidence in a touch, it will clear *only*
the confidence bit. The tipswitch bit will remain set so long as
the touch is tracked. This behavior may be used in future devices.
The driver does not currently handle situation 3 properly. Touches that
loose confidence will remain "in prox" and essentially frozen in place
until the tipswitch bit is finally cleared. Not only does this result
in userspace seeing a stuck touch, but it also prevents pen arbitration
from working properly (the pen won't send events until all touches are
up, but we don't currently process events from non-confident touches).
This commit centralizes the checking of the confidence bit in the
wacom_wac_finger_slot() function and has 'prox' depend on it. In the
case where situation 3 is encountered, the treat the touch as though
it was removed, allowing both userspace and the pen arbitration to
act normally.

commit b3943b3c2971444364e03224cfc828c5789deada upstream.
Ever since introduction in the commit 0c8173385e54 ("rtl8192ce: Add new
driver") the rtlwifi code has, according to comments, attempted to
disable/enable ASPM of the upstream bridge by writing into its LNKCTL
register. However, the code has never been correct because it performs
the writes to the device instead of the upstream bridge.
Worse yet, the offset where the PCIe capabilities reside is derived
from the offset of the upstream bridge. As a result, the write will use
an offset on the device that does not relate to the LNKCTL register
making the ASPM disable/enable code outright dangerous.
Because of those problems, there is no indication that the driver needs
disable/enable ASPM on the upstream bridge. As the Capabilities offset
is not correctly calculated for the write to target device's LNKCTL
register, the code is not disabling/enabling device's ASPM either.
Therefore, just remove the upstream bridge related ASPM disable/enable
code entirely.
The upstream bridge related ASPM code was the only user of the struct
mp_adapter members num4bytes, pcibridge_pciehdr_offset, and
pcibridge_linkctrlreg so those are removed as well.
Note: This change does not remove the code related to changing the
device's ASPM on purpose (which is independent of this flawed code
related to upstream bridge's ASPM).

commit afc95681c3068956fed1241a1ff1612c066c75ac upstream.
In some cases the firmware expects cbndx 1 to be assigned to the GMU,
so we also want the default domain for the GMU to be an identy domain.
This way it does not get a context bank assigned. Without this, both
of_dma_configure() and drm/msm's iommu_domain_attach() will trigger
allocating and configuring a context bank. So GMU ends up attached to
both cbndx 1 and later cbndx 2. This arrangement seemingly confounds
and surprises the firmware if the GPU later triggers a translation
fault, resulting (on sc8280xp / lenovo x13s, at least) in the SMMU
getting wedged and the GPU stuck without memory access.

commit 15e4c1f462279b4e128f27de48133e0debe9e0df upstream.
The driver's fsync() is supposed to flush any pending operation to
hardware. It is implemented in this driver by cancelling the queued
deferred IO first, then schedule it for "immediate execution" by calling
schedule_delayed_work() again with delay=0. However, setting delay=0
only means the work is scheduled immediately, it does not mean the work
is executed immediately. There is no guarantee that the work is finished
after schedule_delayed_work() returns. After this driver's fsync()
returns, there can still be pending work. Furthermore, if close() is
called by users immediately after fsync(), the pending work gets
cancelled and fsync() may do nothing.
To ensure that the deferred IO completes, use flush_delayed_work()
instead. Write operations to this driver either write to the device
directly, or invoke schedule_delayed_work(); so by flushing the
workqueue, it can be guaranteed that all previous writes make it to the
device.

from the probe() function and is now only called through the function
uart_add_one_port() which is located at the end of the probe() function.
But the clock is already switched off in this area. To ensure that the
clock is enabled during register access, move the disabling of the clock
to the very end of the probe() function. To avoid leaking enabled clocks
on error also add an error path for exiting with disabling the clock.

accesses rp->b_size and rp->b_vec without locking, risking array
out-of-bounds access or use-after-free bugs due to possible modifications
in mon_bin_ioctl().
This possible bug is found by an experimental static analysis tool
developed by our team, BassCheck[1]. This tool analyzes the locking APIs
to extract function pairs that can be concurrently executed, and then
analyzes the instructions in the paired functions to identify possible
concurrency bugs including data races and atomicity violations. The above
possible bug is reported when our tool analyzes the source code of
Linux 6.2.
To address this issue, it is proposed to add a spin lock pair in
mon_bin_vma_fault() to ensure atomicity. With this patch applied, our tool
never reports the possible bug, with the kernel configuration allyesconfig
for x86_64. Due to the lack of associated hardware, we cannot test the
patch in runtime testing, and just verify it according to the code logic.

commit e9d40b215e38480fd94c66b06d79045717a59e9c upstream.
Current implementation blocks the running operations when Plug-out and
Plug-In is performed continuously, process gets stuck in
dwc3_thread_interrupt().
Code Flow:
CPU1
->Gadget_start
->dwc3_interrupt
->dwc3_thread_interrupt
->dwc3_process_event_buf
->dwc3_process_event_entry
->dwc3_endpoint_interrupt
->dwc3_ep0_interrupt
->dwc3_ep0_inspect_setup
->dwc3_ep0_stall_and_restart
By this time if pending_list is not empty, it will get the next request
on the given list and calls dwc3_gadget_giveback which will unmap request
and call its complete() callback to notify upper layers that it has
completed. Currently dwc3_gadget_giveback status is set to -ECONNRESET,
whereas it should be -ESHUTDOWN based on condition if not dwc->connected
is true.

When CONFIG_USB_OTG is not set, mxs_phy_is_otg_host() will always return
false. This behaviour is wrong. Since phy.last_event will always be set
for either host or device mode. Therefore, CONFIG_USB_OTG condition

commit 9a9ab0d963621d9d12199df9817e66982582d5a5 upstream.
Task A calls binder_update_page_range() to allocate and insert pages on
a remote address space from Task B. For this, Task A pins the remote mm
via mmget_not_zero() first. This can race with Task B do_exit() and the
final mmput() refcount decrement will come from Task A.
Task A | Task B
------------------+------------------
mmget_not_zero() |
| do_exit()
| exit_mm()
| mmput()
mmput() |
exit_mmap() |
remove_vma() |
fput() |
In this case, the work of ____fput() from Task B is queued up in Task A
as TWA_RESUME. So in theory, Task A returns to userspace and the cleanup
work gets executed. However, Task A instead sleep, waiting for a reply
from Task B that never comes (it's dead).
This means the binder_deferred_release() is blocked until an unrelated
binder event forces Task A to go back to userspace. All the associated
death notifications will also be delayed until then.
In order to fix this use mmput_async() that will schedule the work in
the corresponding mm->async_put_work WQ instead of Task A.

commit c7ec4f2d684e17d69bbdd7c4324db0ef5daac26a upstream.
While frontends may submit zero-size requests (wasting a precious slot),
core networking code as of at least 3ece782693c4b ("sock: skb_copy_ubufs
support for compound pages") can't deal with SKBs when they have all
zero-size fragments. Respond to empty requests right when populating
fragments; all further processing is fragment based and hence won't
encounter these empty requests anymore.
In a way this should have been that way from the beginning: When no data
is to be transferred for a particular request, there's not even a point
in validating the respective grant ref. That's no different from e.g.
passing NULL into memcpy() when at the same time the size is 0.
This is XSA-448 / CVE-2023-46838.

commit 3f489c2067c5824528212b0fc18b28d51332d906 upstream.
The mmap read lock is used during the shrinker's callback, which means
that using alloc->vma pointer isn't safe as it can race with munmap().
As of commit dd2283f2605e ("mm: mmap: zap pages with read mmap_sem in
munmap") the mmap lock is downgraded after the vma has been isolated.
I was able to reproduce this issue by manually adding some delays and
triggering page reclaiming through the shrinker's debug sysfs. The
following KASAN report confirms the UAF:

Fix this issue by performing instead a vma_lookup() which will fail to
find the vma that was isolated before the mmap lock downgrade. Note that
this option has better performance than upgrading to a mmap write lock
which would increase contention. Plus, mmap_write_trylock() has been
recently removed anyway.

The iser_reg_resources structure has two pointers to MR but only one
mr_valid field. The implementation assumes that we use only *sig_mr when
pi_enable is true. Otherwise, we use only *mr. However, it is only
sometimes correct. Read commands without protection information occur even
when pi_enble is true. For example, the following SCSI commands have a
Data-In buffer but never have protection information: READ CAPACITY (16),
INQUIRY, MODE SENSE(6), MAINTENANCE IN. So, we use
*sig_mr for some SCSI commands and *mr for the other SCSI commands.
In most cases, it works fine because the remote invalidation is applied.
However, there are two cases when the remote invalidation is not
applicable.
1. Small write commands when all data is sent as an immediate.
2. The target does not support the remote invalidation feature.
The lazy invalidation is used if the remote invalidation is impossible.
Since, at the lazy invalidation, we always invalidate the MR we want to
use, the wrong MR may be invalidated.
To fix the issue, we need a field per MR that indicates the MR needs
invalidation. Since the ib_mr structure already has such a field, let's
use ib_mr.need_inval instead of iser_reg_resources.mr_valid.

The code does this, but only for iLO5.
The intent was to preserve legacy, Gen9 and earlier, semantics of
using hpwdt for error containtment as hardware/firmware would signal
fatal IO errors as an NMI with the expectation of hpwdt crashing
the system. Howerver, these IO errors should be received by hpwdt
as an NMI_IO_CHECK. So the test is overly permissive and should
not be limited to only ilo5.
We need to enable this protection for future iLOs not matching the

When the new watchdog character device is registered, it becomes
available for opening. This creates a race where userspace may open the
device before the character device's owner is set. This results in an
imbalance in module_get calls as the cdev_get in cdev_open will not
increment the reference count on the watchdog driver module.
This causes problems when the watchdog character device is released as
the module loader's reference will also be released. This makes it
impossible to open the watchdog device later on as it now appears that
the module is being unloaded. The open will fail with -ENXIO from
chrdev_open.
The legacy watchdog device will fail with -EBUSY from the try_module_get
in watchdog_open because it's module owner is the watchdog core module

Currently zynqmp divider round rate is considering single parent and
calculating rate and parent rate accordingly. But if divider clock flag
is set to SET_RATE_PARENT then its not trying to traverse through all
parent rate and not selecting best parent rate from that. So use common
divider_round_rate() which is traversing through all clock parents and
its rate and calculating proper parent rate.

[ Upstream commit b782921ddd7f84f524723090377903f399fdbbcb ]
Currently zynqmp clock driver is not calculating closest mux rate and
because of that Linux is not setting proper frequency for CPU and
not able to set given frequency for dynamic frequency scaling.
E.g., In current logic initial acpu clock parent and frequency as below
apll1 0 0 0 2199999978 0 0 50000 Y
acpu0_mux 0 0 0 2199999978 0 0 50000 Y
acpu0_idiv1 0 0 0 2199999978 0 0 50000 Y
acpu0 0 0 0 2199999978 0 0 50000 Y
After changing acpu frequency to 549999994 Hz using CPU freq scaling its
selecting incorrect parent which is not closest frequency.
rpll_to_xpd 0 0 0 1599999984 0 0 50000 Y
acpu0_mux 0 0 0 1599999984 0 0 50000 Y
acpu0_div1 0 0 0 533333328 0 0 50000 Y
acpu0 0 0 0 533333328 0 0 50000 Y
Parent should remain same since 549999994 = 2199999978 / 4.
So use __clk_mux_determine_rate_closest() generic function to calculate
closest rate for mux clock. After this change its selecting correct
parent and correct clock rate.
apll1 0 0 0 2199999978 0 0 50000 Y
acpu0_mux 0 0 0 2199999978 0 0 50000 Y
