Merge tag 'vfs-6.8.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull misc vfs updates from Christian Brauner:
"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual fses.
Features:
- Add Jan Kara as VFS reviewer
- Show correct device and inode numbers in proc/<pid>/maps for vma
files on stacked filesystems. This is now easily doable thanks to
the backing file work from the last cycles. This comes with
selftests
Cleanups:
- Remove a redundant might_sleep() from wait_on_inode()
- Initialize pointer with NULL, not 0
- Clarify comment on access_override_creds()
- Rework and simplify eventfd_signal() and eventfd_signal_mask()
helpers
- Process aio completions in batches to avoid needless wakeups
- Completely decouple struct mnt_idmap from namespaces. We now only
keep the actual idmapping around and don't stash references to
namespaces
- Reformat maintainer entries to indicate that a given subsystem
belongs to fs/
- Simplify fput() for files that were never opened
- Get rid of various pointless file helpers
- Rename various file helpers
- Rename struct file members after SLAB_TYPESAFE_BY_RCU switch from
last cycle
- Make relatime_need_update() return bool
- Use GFP_KERNEL instead of GFP_USER when allocating superblocks
- Replace deprecated ida_simple_*() calls with their current ida_*()
counterparts
Fixes:
- Fix comments on user namespace id mapping helpers. They aren't
kernel doc comments so they shouldn't be using /**
- s/Retuns/Returns/g in various places
- Add missing parameter documentation on can_move_mount_beneath()
- Rename i_mapping->private_data to i_mapping->i_private_data
- Fix a false-positive lockdep warning in pipe_write() for watch
queues
- Improve __fget_files_rcu() code generation to improve performance
- Only notify writer that pipe resizing has finished after setting
pipe->max_usage otherwise writers are never notified that the pipe
has been resized and hang
- Fix some kernel docs in hfsplus
- s/passs/pass/g in various places
- Fix kernel docs in ntfs
- Fix kcalloc() arguments order reported by gcc 14
- Fix uninitialized value in reiserfs"
* tag 'vfs-6.8.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (36 commits)
reiserfs: fix uninit-value in comp_keys

This is a relatively quiet release, there's a lot of driver specific
changes and the usual high level of activity in the SOF core but the
one big core change was Mormioto-san's work to support more N:M
CPU:CODEC mapping cases. Highlights include:
- Enhanced support for N:M CPU:CODEC mappings in the core and in
audio-graph-card2.
- Support for falling back to older SOF IPC versions where firmware for
new versions is not available.
- Support for notification of control changes generated by SOF firmware
with IPC4.
- Device tree support for describing parts of the card which can be
active over suspend (for very low power playback or wake word use
cases).
- ACPI parsing support for the ES83xx driver, reducing the number of
quirks neede for x86 systems.
- Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm
SM8250, SM8550, SM8650 and X1E80100.
- Removal of Freescale MPC8610 support, the SoC is no longer supported
by Linux.

This driver exposes hardware sensors of the Gigabyte AORUS Waterforce
all-in-one CPU liquid coolers, which communicate through a proprietary
USB HID protocol. Report offsets were initially discovered in [1] and
confirmed by me on a Waterforce X240 by observing the sent reports from
the official software.
Available sensors are pump and fan speed in RPM, as well as coolant
temperature. Also available through debugfs is the firmware version.
Attaching a fan is optional and allows it to be controlled from the
device. If it's not connected, the fan-related sensors will report
zeroes.
The addressable RGB LEDs and LCD screen are not supported in this
driver and should be controlled through userspace tools.

Link topologies containing multiple network PHYs attached to the same
net_device can be found when using a PHY as a media converter for use
with an SFP connector, on which an SFP transceiver containing a PHY can
be used.
With the current model, the transceiver's PHY can't be used for
operations such as cable testing, timestamping, macsec offload, etc.
The reason being that most of the logic for these configuration, coming
from either ethtool netlink or ioctls tend to use netdev->phydev, which
in multi-phy systems will reference the PHY closest to the MAC.
Introduce a numbering scheme allowing to enumerate PHY devices that
belong to any netdev, which can in turn allow userspace to take more
precise decisions with regard to each PHY's configuration.
The numbering is maintained per-netdev, in a phy_device_list.
The numbering works similarly to a netdevice's ifindex, with
identifiers that are only recycled once INT_MAX has been reached.
This prevents races that could occur between PHY listing and SFP
transceiver removal/insertion.
The identifiers are assigned at phy_attach time, as the numbering
depends on the netdevice the phy is attached to.

A late/optimistic second pull request. The bots have been poking them
since Wednesday without any issues. There are a few fixes in the
ad7091r5 driver as part of rework to enable the ad7091r8 parts that
are included at start of that series.
Includes pre-work for major changes to the DMA buffers that should
land in 6.9 and will greatly improve performance and flexibility for
high performance devices by enabling DMABUF based zero copy transfers
when we don't need to bounce the data via user space.
New device support
------------------
adi,ad7091r8
- Major refactor of existing adi,ad7091r5 driver to separate out useful
shared library code that can be used by I2C and SPI parts.
- Use that library from a new driver supporting the AD7091R-2, AD7091R-4
and AD7091R-8 12-Bit SPI ADCs.
- Series includes some late breaking fixes for the ad7091r5.
microchip,mcp4821
- New driver for MCP4801, MCP4802, MCP4811, MCP4812, MCP4821 and MCP4822
I2C single / dual channel DACs.
Cleanup
-------
buffers:
- Use IIO_SEPARATE in place of some hard-coded 0 values.
dma-buffers:
- Simplify things to not use an outgoing queue given it only ever has
up to two elements and we only need to track which is first.
- Split the iio_dma_buffer_fileio_free() function up to make it easier
to read and enable reuse in a series lining up for 6.9
iio.h
- Drop some stale documentation of struct fields that don't exist.

IIO: 2nd set of new device support, features and cleanup for 6.8
A late/optimistic second pull request. The bots have been poking them
since Wednesday without any issues. There are a few fixes in the
ad7091r5 driver as part of rework to enable the ad7091r8 parts that
are included at start of that series.
Includes pre-work for major changes to the DMA buffers that should
land in 6.9 and will greatly improve performance and flexibility for
high performance devices by enabling DMABUF based zero copy transfers
when we don't need to bounce the data via user space.
New device support
------------------
adi,ad7091r8
- Major refactor of existing adi,ad7091r5 driver to separate out useful
shared library code that can be used by I2C and SPI parts.
- Use that library from a new driver supporting the AD7091R-2, AD7091R-4
and AD7091R-8 12-Bit SPI ADCs.
- Series includes some late breaking fixes for the ad7091r5.
microchip,mcp4821
- New driver for MCP4801, MCP4802, MCP4811, MCP4812, MCP4821 and MCP4822
I2C single / dual channel DACs.
Cleanup
-------
buffers:
- Use IIO_SEPARATE in place of some hard-coded 0 values.
dma-buffers:
- Simplify things to not use an outgoing queue given it only ever has
up to two elements and we only need to track which is first.
- Split the iio_dma_buffer_fileio_free() function up to make it easier
to read and enable reuse in a series lining up for 6.9
iio.h
- Drop some stale documentation of struct fields that don't exist.

Add MACsec support.
The MACsec block has four TX SCs and four RX SCs. The driver supports up
to four SecY. Each SecY with one TX SC and one RX SC.
The RX SCs can have two keys, key A and key B, written in hardware and
enabled at the same time.
The TX SCs can have two keys written in hardware, but only one can be
active at a given time.
On TX, the SC is selected using the MAC source address. Due of this
selection mechanism, each offloaded netdev must have a unique MAC
address.
On RX, the SC is selected by SCI(found in SecTAG or calculated using MAC
SA), or using RX SC 0 as implicit.

There's a problem with dependencies between netfslib and fscache as each
wants to access some functions of the other. Deal with this by moving
fs/fscache/* into fs/netfs/ and renaming those files to begin with
"fscache-".
For the moment, the moved files are changed as little as possible and an
fscache module is still built. A subsequent patch will integrate them.

Eric Paris is an important part of SELinux history and we are all

several years (his last SELinux kernel commit was in 2013) so it's
time to officially drop Eric as a maintainer.
I also want to get ahead of any claims of impropriety and state that

Having a platform need a mach-* directory should be seen as a negative,
it means the platform needs special non-standard handling. ARM64 support
does not allow mach-* directories at all. While we may not get to that
given all the non-standard architectures we support, we should still try
to get as close as we can and reduce the number of mach directories.
The mach-sunplus/ directory and files, provides just one "feature":
having the kernel print the machine name if the DTB does not also contain
a "model" string (which they always do). To reduce the number of mach-*
directories let's do without that feature and remove this directory.
NOTE: The default l2c_aux_mask is now ~0 but these devices never have
this type of cache controller so this is safe.

Support for SM8650 and X1E is added to the LLCC driver, the
LLCC_TRP_ATTR2_CFGn register stride is corrected, and a bug where for
each iteration looping over slices previous settings for dis_cap_alloc
and retain_on_pc are overwritten.
A quirk is introduced in UCSI, for implementations that does not handle
UCSI_GET_PDOS for non-PD partners. With this, USCI support is enabled by
default in pmic_glink. It is later reverted for SC8280XP due reported
errors.
A few memory leaks in error paths of qseecom are taken care of.
A small driver to expose the ADSP PDCharger ULOG debug log is
introduced, to aid debugging issues with pmic_glink.
The identiy of SM8650, PM8937 and a few DSPs are added to the Qualcomm
socinfo driver.
The Qualcomm sleep stats driver is extended to allow getting detailed
statistics about usage of various DDR states. Unfortunately this ABI
does not seem to be stable across platforms, so this addition is dropped
again while the reported problems are investigated further.
Andy is moved from MAINTAINERS to CREDITS. Thank you, Andy.

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms. The experimental support starts with Tiger Lake.
i915 will continue be the main production driver for the platforms
up to Meteor Lake and Alchemist. Then the goal is to make this Intel
Xe driver the primary driver for Lunar Lake and newer platforms.
It uses most, if not all, of the key drm concepts, in special: TTM,
drm-scheduler, drm-exec, drm-gpuvm/gpuva and others.

Adds driver for the MCP48xx series of DACs.
Device uses a simplex SPI channel. To set the value of an output channel,
a 16-bit data of following format must be written:
Bit field | Description
15 [MSB] | Channel selection bit
0 -> Channel A
1 -> Channel B
13 | Output Gain Selection bit
0 -> 2x Gain (Vref = 4.096V)
1 -> 1x Gain (Vref = 2.048V)
12 | Output Shutdown Control bit
0 -> Shutdown the selected channel
1 -> Active mode operation
11-0 [LSB]| DAC Input Data bits
Value's big endian representation is taken as input for the
selected DAC channel. For devices with a resolution of less
than 12-bits, only the x most significant bits are considered
where x is the resolution of the device.
Reference: Page#22 [MCP48x2 Datasheet]
Supported devices:
+---------+--------------+-------------+
| Device | Resolution | Channels |
|---------|--------------|-------------|
| MCP4801 | 8-bit | 1 |
| MCP4802 | 8-bit | 2 |
| MCP4811 | 10-bit | 1 |

Introduce the Maintainers of the new drm/xe driver for upcoming
Intel GPUs.
Since it has a shared display with drm/i915, let's also create a
dedicated block to group display related files. But without any
substantial change to the i915 side. The display patches will
continue to flow through i915 from drm-intel-next branches for now.

Cleanup
-------

Some PWM devices require sleeping, for example if the pwm device is
connected over I2C. However, many PWM devices could be used from atomic
context, e.g. memory mapped PWM. This is useful for, for example, the
pwm-ir-tx driver which requires precise timing. Sleeping causes havoc
with the generated IR signal.
Since not all PWM devices can support atomic context, we also add a

In order to introduce a pwm api which can be used from atomic context,
we will need two functions for applying pwm changes:
int pwm_apply_might_sleep(struct pwm *, struct pwm_state *);
int pwm_apply_atomic(struct pwm *, struct pwm_state *);
This commit just deals with renaming pwm_apply_state(), a following
commit will introduce the pwm_apply_atomic() function.

Introduce a vfio driver over virtio devices to support the legacy
interface functionality for VFs.
Background, from the virtio spec [1].
--------------------------------------------------------------------
In some systems, there is a need to support a virtio legacy driver with
a device that does not directly support the legacy interface. In such
scenarios, a group owner device can provide the legacy interface
functionality for the group member devices. The driver of the owner
device can then access the legacy interface of a member device on behalf
of the legacy member device driver.
For example, with the SR-IOV group type, group members (VFs) can not
present the legacy interface in an I/O BAR in BAR0 as expected by the
legacy pci driver. If the legacy driver is running inside a virtual
machine, the hypervisor executing the virtual machine can present a
virtual device with an I/O BAR in BAR0. The hypervisor intercepts the
legacy driver accesses to this I/O BAR and forwards them to the group
owner device (PF) using group administration commands.
--------------------------------------------------------------------
Specifically, this driver adds support for a virtio-net VF to be exposed
as a transitional device to a guest driver and allows the legacy IO BAR
functionality on top.
This allows a VM which uses a legacy virtio-net driver in the guest to
work transparently over a VF which its driver in the host is that new
driver.
The driver can be extended easily to support some other types of virtio
devices (e.g virtio-blk), by adding in a few places the specific type
properties as was done for virtio-net.
For now, only the virtio-net use case was tested and as such we introduce
the support only for such a device.
Practically,
Upon probing a VF for a virtio-net device, in case its PF supports
legacy access over the virtio admin commands and the VF doesn't have BAR
0, we set some specific 'vfio_device_ops' to be able to simulate in SW a
transitional device with I/O BAR in BAR 0.
The existence of the simulated I/O bar is reported later on by
overwriting the VFIO_DEVICE_GET_REGION_INFO command and the device
exposes itself as a transitional device by overwriting some properties
upon reading its config space.
Once we report the existence of I/O BAR as BAR 0 a legacy driver in the
guest may use it via read/write calls according to the virtio
specification.
Any read/write towards the control parts of the BAR will be captured by
the new driver and will be translated into admin commands towards the
device.
In addition, any data path read/write access (i.e. virtio driver
notifications) will be captured by the driver and forwarded to the
physical BAR which its properties were supplied by the admin command
VIRTIO_ADMIN_CMD_LEGACY_NOTIFY_INFO upon the probing/init flow.
With that code in place a legacy driver in the guest has the look and
feel as if having a transitional device with legacy support for both its
control and data path flows.

His first major IMA contribution was IMA template support. He also
contributed extending TPM 2.0 PCRs with properly calculated per TPM
bank digests and included file metadata information in the IMA
measurement list.
Regarding EVM, Roberto contributed to making EVM portable and immutable
signatures more usable. He also prepared the LSM infrastructure to
support EVM as a fully fledged LSM, by ensuring that the latter receives
from the former all xattrs provided by other registered LSMs at inode
creation time, for HMAC calculation.
Roberto is currently working on making IMA and EVM full fledged LSMs.

Steps in reading the VOC sensor value over i2c:
1. Read 5 bytes from the register `AGS02MA_TVOC_READ_REG` [0x00]
2. The first 4 bytes are taken as the big endian sensor data with final
byte being the CRC
3. The CRC is verified and the value is returned over an
`IIO_CHAN_INFO_RAW` channel as percents

Although the file has not been touched a lot lately, the git history tells
us that Gregory Clement and Andrew Lunn integrated patches specific to
this driver code. Further, the driver's config depends on config
PLAT_ORION, and the code for this platform is defined in

MLX90635 is an Infra Red contactless temperature sensor most suitable
for consumer applications where measured object temperature is in range
between -20 to 100 degrees Celsius. It has improved accuracy for
measurements within temperature range of human body and can operate in
ambient temperature range between -20 to 85 degrees Celsius.
Driver provides simple power management possibility as it returns to
lowest possible power mode (Step sleep mode) in which temperature
measurements can still be performed, yet for continuous measuring it
switches to Continuous power mode where measurements constantly change
without triggering.

Patch series "samples: introduce cgroup events listeners", v3.
To begin with, this patch series relocates the cgroup example code to the
samples/cgroup directory, which is the appropriate location for such code
snippets.
Furthermore, a new memcg events listener is introduced. This listener is
a simple yet effective tool for monitoring memory events and managing
counter changes during runtime.
Additionally, as per Andrew Morton's suggestion, a helpful reminder
comment is included in the memcontrol implementation. This comment serves
to ensure that the samples code is updated whenever new events are added.
This patch (of 3):
Move the cgroup_event_listener for cgroup v1 to the samples directory.
This suggestion was proposed by Andrew Morton during the discussion [1].

different subsystem drivers.
Split overall TEE subsystem documentation modularly where:
- The userspace API has been moved to Documentation/userspace-api/tee.rst.
- The driver API has been moved to Documentation/driver-api/tee.rst.
- The first module covers the overview of TEE subsystem.
- The further modules are dedicated to different TEE implementations like:
- OP-TEE
- AMD-TEE
- and so on for future TEE implementation support.

The MAINTAINERS entry's F: currently only matches the 32-bit device trees,
as commit 724ba67515 ("ARM: dts: Move .dts files to vendor sub-directories")
inadvertently dropped the 64-bit DT match when it added the 32 bit
matches. The entry has a N: imx, which reduced the impact a bit, but
still some board device trees may not contain the substring and would
thus not be covered by the entry.
Reinstate the missing F: line to restore previous behavior.

The Vishay VEMl6075 is a low power, 16-bit resolution UVA and UVB
light sensor with I2C interface and noise compensation (visible and
infrarred).
Every UV channel generates an output signal measured in counts per
integration period, where the integration time is configurable.
This driver adds support for both UV channels and the ultraviolet
index (UVI) inferred from them according to the device application note
with open-air (no teflon) coefficients.

Merge series from Nam Cao <namcao@linutronix.de>:
While running the spl022, I got the following warning:
BUG: sleeping function called from invalid context at drivers/spi/spi.c:1428
This is because between spi transfers, spi_transfer_delay_exec() (who
may sleep if the delay is >10us) is called in interrupt context. This is
a problem for anyone who runs this driver and need more than 10us delay.
Patch 1 adds an error reporting mechanism, needed by patch 2 who switch
to use the default spi_transfer_one_message(), which fix the problem.
The series is tested with polling transfer mode and interrupt transfer
mode. I can't test the DMA mode, so some help testing here is very
appreciated.

The THP7312 is an external ISP from THine. As such, it implements a
large number of parameters to control all aspects of the image
processing. Many of those controls are already standard in V4L2, but
some are fairly device-specific.
Reserve a range of 32 controls for the device. The driver will implement
4 device-specific controls to start with, define and document them. 28
additional device-specific controls should be enough for future
development.

Addition of support for the Galaxy Core GC2145 XVGA sensor.
The sensor supports both DVP and CSI-2 interfaces however for
the time being only CSI-2 is implemented.
Configurations are currently based on initialization scripts
coming from Galaxy Core and so for that purpose only 3 static
resolutions are supported:
- 640x480
- 1280x720
- 1600x1200

Analyzed a few structs in the networking stack by looking at variables
within them that are used in the TCP/IP fast path.
Fast path is defined as TCP path where data is transferred from sender to
receiver unidirectionally. It doesn't include phases other than
TCP_ESTABLISHED, nor does it look at error paths.
We hope to re-organizing variables that span many cachelines whose fast
path variables are also spread out, and this document can help future
developers keep networking fast path cachelines small.
Optimized_cacheline field is computed as
(Fastpath_Bytes/L3_cacheline_size_x86), and not the actual organized
results (see patches to come for these).
Investigation is done on 6.5
Name Struct_Cachelines Cur_fastpath_cache Fastpath_Bytes Optimized_cacheline
tcp_sock 42 (2664 Bytes) 12 396 8
net_device 39 (2240 bytes) 12 234 4
inet_sock 15 (960 bytes) 14 922 14
Inet_connection_sock 22 (1368 bytes) 18 1166 18
Netns_ipv4 (sysctls) 12 (768 bytes) 4 77 2
linux_mib 16 (1060) 6 104 2
Note how there isn't much improvement space for inet_sock and
Inet_connection_sock because sk and icsk_inet respectively takes up so
much of the struct that rest of the variables become a small portion of
the struct size.
So, we decided to reorganize tcp_sock, net_device, netns_ipv4

While doing some code cleanup in drivers/bus/, I noticed that the files
drivers/bus/omap*.[ch] have no maintainer.
As far as I see from the git history, important changes to those files went
through Tony Lindgren. Further, the inclusion of those drivers depend on
the config ARCH_OMAP2PLUS being enabled. This suggests these drivers are
part of the section OMAP2+ SUPPORT.
Add the omap bus drivers to OMAP2+ SUPPORT.

When running Linux inside a Nitro Enclave, the hypervisor provides a
special virtio device called "Nitro Security Module" (NSM). This device
has 3 main functions:
1) Provide attestation reports
2) Modify PCR state
3) Provide entropy
This patch adds a driver for NSM that exposes a /dev/nsm device node which
user space can issue an ioctl on this device with raw NSM CBOR formatted
commands to request attestation documents, influence PCR states, read
entropy and enumerate status of the device. In addition, the driver
implements a hwrng backend.

As discussed at the ClangBuiltLinux '23 meetup (co-located with Linux Plumbers
Conf '23), I'll be taking a step back from kernel work to focus on my growing
family and helping Google figure out its libc story. So I think it's time to
formally hand over the reigns to my co-maintainer Nathan.
As such, remove myself from reviewer for:
- CLANG CONTROL FLOW INTEGRITY SUPPORT
- COMPILER ATTRIBUTES
- KERNEL BUILD
For CLANG/LLVM BUILD SUPPORT I'm bumping myself down from maintainer to
reviewer, adding Bill and Justin, and removing Tom (Tom and I confirmed this
via private email; thanks for the work done Tom, ++beers_owed).
It has been my pleasure to work with everyone to improve the toolchain
portability of the Linux kernel, and to help bring LLVM to the table as a
competitor. The work here is not done. I have a few last LLVM patches in the
works to improve stack usage of clang which has been our longest standing open
issue (getting "rm" inline asm constraints to DTRT is part of that). But
looking back I'm incredibly proud of where we are to today relative to where we
were when we started the ClangBuiltLinux journey, and am confident that the
team and processes we have put in place will continue to be successful. I
continue to believe that a rising tide will lift all boats.
I identify first and foremost as a Linux kernel developer, and an LLVM dev
second. May it be a cold day in hell when that changes.
Wake me when you need me.

Commit 33ec3e5fc1 ("iio: adc: adding support for MCP3564 ADC") adds a new
iio driver and corresponding MAINTAINERS section. It however uses spaces
instead of a single tab for all the entries in that MAINTAINERS section.
Although, the get_maintainer.pl script handles spaces instead of tabs
silently, the MAINTAINERS will quickly get into a messy state with
different indentations throughout the file. So, the checkpatch.pl script
complains when spaces instead of a single tab are used.
Fix this recently added section using tabs instead of spaces.
Further, add the driver's ABI documentation file to this section as well.

The Monolithic Power (MPS) MP3309C is a WLED step-up converter, featuring a
programmable switching frequency to optimize efficiency.
The brightness can be controlled either by I2C commands (called "analog"
mode) or by a PWM input signal (PWM mode).
This driver supports both modes.
For DT configuration details, please refer to:
- Documentation/devicetree/bindings/leds/backlight/mps,mp3309c.yaml
The datasheet is available at:

indirect_call_wrapper.h is not, strictly speaking, networking specific.
However, it's git history indicates that in practice changes go through
netdev and thus the netdev maintainers have effectively been taking
responsibility for it.
Formalise this by adding it to the NETWORKING [GENERAL] section in the
MAINTAINERS file.
It is not clear how many other files under include/linux fall into this
category and it would be interesting, as a follow-up, to audit that and
propose further updates to the MAINTAINERS file as appropriate.
