The Lenovo ThinkPad W530 uses a nvidia k1000m GPU. When this gets used
together with one of the older nvidia binary driver series (the latest
series does not support it), then backlight control does not work.
This is caused by commit 3dbc80a3e4c5 ("ACPI: video: Make backlight
class device registration a separate step (v2)") combined with
commit 5aa9d943e9b6 ("ACPI: video: Don't enable fallback path for
creating ACPI backlight by default").
After these changes the acpi_video# backlight device is only registered
when requested by a GPU driver calling acpi_video_register_backlight()
which the nvidia binary driver does not do.
I realize that using the nvidia binary driver is not a supported use-case
and users can workaround this by adding acpi_backlight=video on the kernel
commandline, but the ThinkPad W530 is a popular model under Linux users,
so it seems worthwhile to add a quirk for this.
I will also email Nvidia asking them to make the driver call
acpi_video_register_backlight() when an internal LCD panel is detected.
So maybe the next maintenance release of the drivers will fix this...

On the Apple iMac14,1 and iMac14,2 all-in-ones (monitors with builtin "PC")
the connection between the GPU and the panel is seen by the GPU driver as
regular DP instead of eDP, causing the GPU driver to never call
acpi_video_register_backlight().
(GPU drivers only call acpi_video_register_backlight() when an internal
panel is detected, to avoid non working acpi_video# devices getting
registered on desktops which unfortunately is a real issue.)
Fix the missing acpi_video# backlight device on these all-in-ones by
adding a acpi_backlight=video DMI quirk, so that video.ko will
immediately register the backlight device instead of waiting for
an acpi_video_register_backlight() call.

Commit 3dbc80a3e4c5 ("ACPI: video: Make backlight class device
registration a separate step (v2)") combined with
commit 5aa9d943e9b6 ("ACPI: video: Don't enable fallback path for
creating ACPI backlight by default")
Means that the video.ko code now fully depends on the GPU driver calling
acpi_video_register_backlight() for the acpi_video# backlight class
devices to get registered.
This means that if the GPU driver does not do this, acpi_backlight=video
on the cmdline, or DMI quirks for selecting acpi_video# will not work.
This is a problem on for example Apple iMac14,1 all-in-ones where
the monitor's LCD panel shows up as a regular DP connection instead of
eDP so the GPU driver will not call acpi_video_register_backlight() [1].
Fix this by making video.ko directly register the acpi_video# devices
when these have been explicitly requested either on the cmdline or
through DMI quirks (rather then auto-detection being used).
[1] GPU drivers only call acpi_video_register_backlight() when an internal
panel is detected, to avoid non working acpi_video# devices getting
registered on desktops which unfortunately is a real issue.

Allow callers of __acpi_video_get_backlight_type() to pass a pointer
to a bool which will get set to false if the backlight-type comes from
the cmdline or a DMI quirk and set to true if auto-detection was used.
And make __acpi_video_get_backlight_type() non static so that it can
be called directly outside of video_detect.c .
While at it turn the acpi_video_get_backlight_type() and
acpi_video_backlight_use_native() wrappers into static inline functions
in include/acpi/video.h, so that we need to export one less symbol.

The device can report discard support without setting the ONCS DSM bit.
When not set, the driver clears max_discard_size expecting it to be set
later. We don't know the size until we have the namespace format,
though, so setting it is deferred until configuring one, but the driver
was abandoning the discard settings due to that initial clearing.
Move the max_discard_size calculation above the check for a '0' discard
size.

When calling dev_set_name() memory is allocated for the name for the
struct device. Once that structure device is registered, or attempted
to be registerd, with the driver core, the driver core will handle
cleaning up that memory when the device is removed from the system.
Unfortunatly for the memstick code, there is an error path that causes
the struct device to never be registered, and so the memory allocated in
dev_set_name will be leaked. Fix that leak by manually freeing it right
before the memory for the device is freed.

Currently job->done_fence is added to every BO handle within a job. If job
handle (command buffer) is shared between multiple submits, KMD will add
the fence in each of them. Then bo_wait_ioctl() executed on command buffer
will exit only when all jobs containing that handle are done.
This creates deadlock scenario for user mode driver in case when job handle
is added as dependency of another job, because bo_wait_ioctl() of first job
will wait until second job finishes, and second job can not finish before
first one.
Having fences added only to job buffer handle allows user space to execute
bo_wait_ioctl() on the job even if it's handle is submitted with other job.

One motivation for mapping range registers to decoder objects is
to use those settings for region autodiscovery.
The need to map a region for devices programmed to use range registers
is especially urgent now that the kernel no longer routes "Soft
Reserved" ranges in the memory map to device-dax by default. The CXL
memory range loses all access mechanisms.
Complete the implementation by marking the DPA reservation and setting
the endpoint-decoder state to signal autodiscovery. Note that the
default settings of ways=1 and granularity=4096 set in cxl_decode_init()
do not need to be updated.

Recall that range register emulation seeks to treat the 2 potential
range registers as Linux CXL "decoder" objects. The number of range
registers can be 1 or 2, while HDM decoder ranges can include more than
2.
Be careful not to confuse DVSEC range count with HDM capability decoder
count. Commit to range register earlier in devm_cxl_setup_hdm().
Otherwise, a device with more HDM decoders than range registers can set
@cxlhdm->decoder_count to an invalid value.
Avoid introducing a forward declaration by just moving the definition of
should_emulate_decoders() earlier in the file. should_emulate_decoders()
is unchanged.

Each time the contents of a given HPA are potentially changed in a cache
incoherent manner the CXL core sets CXL_REGION_F_INCOHERENT to
invalidate CPU caches before the region is used.
Successful invocation of attach_target() indicates that DPA has been
newly assigned to a given HPA in the dynamic region creation flow.
However, attach_target() is also reused in the autodiscovery flow where
the region was activated by platform firmware. In that case there is no
need to invalidate caches because that region is already in active use
and nothing about the autodiscovery flow modifies the HPA-to-DPA
relationship.
In the autodiscovery case cxl_region_attach() exits early after
determining the endpoint decoder is already correctly attached to the
region.

RCDs (CXL memory devices that link train without VH capability and show
up as root complex integrated endpoints), hide the presence of the link
between the endpoint and the host-bridge. The CXL region setup/teardown
paths assume that a link hop is present and go looking for at least one
'struct cxl_port' instance between the CXL root port-object and an
endpoint port-object leading to crashes of the form:

The find_cxl_root() helper is used to lookup root decoders and other CXL
platform topology information for a given endpoint. It turns out that
for RCDs it has never worked. The result of find_cxl_root(&cxlmd->dev)
is always NULL for the RCH topology case because it expects to find a
cxl_port at the host-bridge. RCH topologies only have the root cxl_port
object with the host-bridge as a dport. While there are no reports of
this being a problem to date, by inspection region enumeration should
crash as a result of this problem, and it does in a local unit test for
this scenario.
However, an observation that ever since:
commit f17b558d6663 ("cxl/pmem: Refactor nvdimm device registration, delete the workqueue")
...all callers of find_cxl_root() occur after the memdev connection to
the port topology has been established. That means that find_cxl_root()
can be simplified to a walk of the endpoint port topology to the root.
Switch to that arrangement which also fixes the RCD bug.

So for example vdpasim_net_work(), which uses the net->*_stats variables,

The right place to add the debugfs create is in
setup_driver() and remove it in teardown_driver().
Current code adds the debugfs when creating the device but resetting a

We normally clear the endpoint then unmap LUNs so the devices are fully
shutdown when the LUN is unmapped, but it's legal to unmap before
clearing. If the user does that while TMFs are running then we can end
up crashing.
vhost_scsi_port_unlink assumes that the LUN's tmf struct will always be on
the tmf_queue list. However, if a TMF is running then it will have been
removed while it's executing. If we do a LUN unmap at this time, then
we assume the entry is on the list and just start accessing it and free
it.
This fixes the bug by just allocating the vhost_scsi_tmf struct when it's
needed like is done with the se_tmr struct that's needed when we submit
the TMF. In this path perf is not an issue and we can use GFP_KERNEL
since it won't swing directly back on us, so we don't need to preallocate
the struct.

If vhost_scsi_setup_vq_cmds fails we leave the tpg->vhost_scsi pointer
set. If the device is freed and then the user unmaps the LUN, the call to
vhost_scsi_port_unlink -> vhost_scsi_hotunplug will see the that
tpg->vhost_scsi is still set and try to use it.
This has us clear the vhost_scsi pointer in the failure path. It also
has us take tv_tpg_mutex in this failure path, because tv_tpg_vhost_count
is accessed under this mutex in vhost_scsi_drop_nexus and in the future
we will want to serialize access to tpg->vhost_scsi with that mutex
instead of the vhost_scsi_mutex.

When the kernel is built without support for zoned block devices,
virtio-blk probe needs to error out any host-managed device scans
to prevent such devices from appearing in the system as non-zoned.
The current virtio-blk code simply bypasses all ZBD checks if
CONFIG_BLK_DEV_ZONED is not defined and this leads to host-managed
block devices being presented as non-zoned in the OS. This is one of
the main problems this patch series is aimed to fix.
In this patch, make VIRTIO_BLK_F_ZONED feature defined even when
CONFIG_BLK_DEV_ZONED is not. This change makes the code compliant with
the voted revision of virtio-blk ZBD spec. Modify the probe code to
look at the situation when VIRTIO_BLK_F_ZONED is negotiated in a kernel
that is built without ZBD support. In this case, the code checks
the zoned model of the device and fails the probe is the device
is host-managed.
The patch also adds the comment to clarify that the call to perform
the zoned device probe is correctly placed after virtio_device ready().

The merged patch series to support zoned block devices in virtio-blk
is not the most up to date version. The merged patch can be found at
https://lore.kernel.org/linux-block/20221016034127.330942-3-dmitry.fomichev@wdc.com/
but the latest and reviewed version is
https://lore.kernel.org/linux-block/20221110053952.3378990-3-dmitry.fomichev@wdc.com/
The reason is apparently that the correct mailing lists and
maintainers were not copied.
The differences between the two are mostly cleanups, but there is one
change that is very important in terms of compatibility with the
approved virtio-zbd specification.
Before it was approved, the OASIS virtio spec had a change in
VIRTIO_BLK_T_ZONE_APPEND request layout that is not reflected in the
current virtio-blk driver code. In the running code, the status is
the first byte of the in-header that is followed by some pad bytes
and the u64 that carries the sector at which the data has been written
to the zone back to the driver, aka the append sector.
This layout turned out to be problematic for implementing in QEMU and
the request status byte has been eventually made the last byte of the
in-header. The current code doesn't expect that and this causes the
append sector value always come as zero to the block layer. This needs
to be fixed ASAP.

stmmac_reinit_queues() fails to fix up the RX hash. Even if the number
of channels gets restricted, the output of `ethtool -x' indicates that
all RX queues are used:
$ ethtool -l enp0s29f2
Channel parameters for enp0s29f2:
Pre-set maximums:
RX: 8
TX: 8
Other: n/a
Combined: n/a
Current hardware settings:
RX: 8
TX: 8
Other: n/a
Combined: n/a
$ ethtool -x enp0s29f2
RX flow hash indirection table for enp0s29f2 with 8 RX ring(s):

Fix this by setting the indirection table according to the number

syzkaller found that the calculation of batch_last_index should use
'start_index' since at input to this function the batch is either empty or
it has already been adjusted to cross any accesses so it will start at the
point we are unmapping from.
Getting this wrong causes the unmap to run over the end of the pages
which corrupts pages that were never mapped. In most cases this triggers
the num pinned debugging:

In the am65_cpsw_nuss_probe() function's cleanup path, the call to
of_platform_device_destroy() for the common->mdio_dev device is invoked
unconditionally. It is possible that either the MDIO node is not present
in the device-tree, or the MDIO node is disabled in the device-tree. In
both these cases, the MDIO device is not created, resulting in a NULL
pointer dereference when the of_platform_device_destroy() function is
invoked on the common->mdio_dev device on the cleanup path.
Fix this by ensuring that the common->mdio_dev device exists, before
attempting to invoke of_platform_device_destroy().

Gregory Price reports a WARN splat with CONFIG_DEBUG_OBJECTS=y upon CXL
probing because pci_doe_submit_task() invokes INIT_WORK() instead of
INIT_WORK_ONSTACK() for a work_struct that was allocated on the stack.
All callers of pci_doe_submit_task() allocate the work_struct on the
stack, so replace INIT_WORK() with INIT_WORK_ONSTACK() as a backportable
short-term fix.
The long-term fix implemented by a subsequent commit is to move to a
synchronous API which allocates the work_struct internally in the DOE
library.

If the length in the CDAT header is larger than the concatenation of the
header and all table entries, then the CDAT exposed to user space
contains trailing null bytes.
Not every consumer may be able to handle that. Per Postel's robustness
principle, "be liberal in what you accept" and silently reduce the
cached length to avoid exposing those null bytes.

If truncated CDAT entries are received from a device, the concatenation
of those entries constitutes a corrupt CDAT, yet is happily exposed to
user space.
Avoid by verifying response lengths and erroring out if truncation is
detected.
The last CDAT entry may still be truncated despite the checks introduced
herein if the length in the CDAT header is too small. However, that is
easily detectable by user space because it reaches EOF prematurely.
A subsequent commit which rightsizes the CDAT response allocation closes
that remaining loophole.
The two lines introduced here which exceed 80 chars are shortened to
less than 80 chars by a subsequent commit which migrates to a
synchronous DOE API and replaces "t.task.rv" by "rc".
The existing acpi_cdat_header and acpi_table_cdat struct definitions
provided by ACPICA cannot be used because they do not employ __le16 or
__le32 types. I believe that cannot be changed because those types are
Linux-specific and ACPI is specified for little endian platforms only,
hence doesn't care about endianness. So duplicate the structs.

cxl_cdat_get_length() only checks whether the DOE response size is
sufficient for the Table Access response header (1 dword), but not the
succeeding CDAT header (1 dword length plus other fields).
It thus returns whatever uninitialized memory happens to be on the stack
if a truncated DOE response with only 1 dword was received. Fix it.
