db52926fb0 HID: Intel-thc-hid: Intel-quickspi: Correct device state after S4
During S4 retore flow, quickspi device was resetted by driver and state
was changed to RESETTED. It is needed to be change to ENABLED state
after S4 re-initialization finished, otherwise, device will run in wrong
state and HID input data will be dropped.

e53fc232a6 HID: hid-steam: Fix use-after-free when detaching device
When a hid-steam device is removed it must clean up the client_hdev used for
intercepting hidraw access. This can lead to scheduling deferred work to
reattach the input device. Though the cleanup cancels the deferred work, this
was done before the client_hdev itself is cleaned up, so it gets rescheduled.
This patch fixes the ordering to make sure the deferred work is properly
canceled.

This happens due to the malformed report items sent by the emulated device
which results in a report, that has no fields, being added to the report list.
Due to this appleir_input_configured() is never called, hidinput_connect()
fails which results in the HID_CLAIMED_INPUT flag is not being set. However,
it  does not make appleir_probe() fail and lets the event callback to be
called without the associated input device.

Thus, add a check for the HID_CLAIMED_INPUT flag and leave the event hook
early if the driver didn't claim any input_dev for some reason. Moreover,
some other hid drivers accessing input_dev in their event callbacks do have
similar checks, too.

221cea1003 HID: apple: disable Fn key handling on the Omoton KB066
Remove the fixup to make the Omoton KB066's F6 key F6 when not holding
Fn. That was really just a hack to allow typing F6 in fnmode>0, and it
didn't fix any of the other F keys that were likewise untypable in
fnmode>0. Instead, because the Omoton's Fn key is entirely internal to
the keyboard, completely disable Fn key translation when an Omoton is
detected, which will prevent the hid-apple driver from interfering with
the keyboard's built-in Fn key handling. All of the F keys, including
F6, are then typable when Fn is held.

The Omoton KB066 and the Apple A1255 both have HID product code
05ac:022c. The self-reported name of every original A1255 when they left
the factory was "Apple Wireless Keyboard". By default, Mac OS changes
the name to "<username>'s keyboard" when pairing with the keyboard, but
Mac OS allows the user to set the internal name of Apple keyboards to
anything they like. The Omoton KB066's name, on the other hand, is not
configurable: It is always "Bluetooth Keyboard". Because that name is so
generic that a user might conceivably use the same name for a real Apple
keyboard, detect Omoton keyboards based on both having that exact name
and having HID product code 022c.

07583a0010 HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove()
The system can experience a random crash a few minutes after the driver is
removed. This issue occurs due to improper handling of memory freeing in
the ishtp_hid_remove() function.

The function currently frees the `driver_data` directly within the loop
that destroys the HID devices, which can lead to accessing freed memory.
Specifically, `hid_destroy_device()` uses `driver_data` when it calls
`hid_ishtp_set_feature()` to power off the sensor, so freeing
`driver_data` beforehand can result in accessing invalid memory.

This patch resolves the issue by storing the `driver_data` in a temporary
variable before calling `hid_destroy_device()`, and then freeing the
`driver_data` after the device is destroyed.

8239878414 HID: intel-ish-hid: Fix use-after-free issue in hid_ishtp_cl_remove()
During the `rmmod` operation for the `intel_ishtp_hid` driver, a
use-after-free issue can occur in the hid_ishtp_cl_remove() function.
The function hid_ishtp_cl_deinit() is called before ishtp_hid_remove(),
which can lead to accessing freed memory or resources during the
removal process.

Additionally, ishtp_hid_remove() is a HID level power off, which should
occur before the ISHTP level disconnect.

This patch resolves the issue by reordering the calls in
hid_ishtp_cl_remove(). The function ishtp_hid_remove() is now
called before hid_ishtp_cl_deinit().

Syzbot[1] has detected a stack-out-of-bounds read of the ep_addr array from

function from usb.c core driver, which executes a for loop that iterates
over the elements of the passed array. Not finding a null element at the end of

To fix this, a 0 element was added at the end of the array to break the for
loop.

819083cb6e HID: apple: fix up the F6 key on the Omoton KB066 keyboard
The Omoton KB066 is an Apple A1255 keyboard clone (HID product code
05ac:022c). On both keyboards, the F6 key becomes Num Lock when the Fn
key is held. But unlike its Apple exemplar, when the Omoton's F6 key is
pressed without Fn, it sends the usage code 0xC0301 from the reserved
section of the consumer page instead of the standard F6 usage code
0x7003F from the keyboard page. The nonstandard code is translated to
KEY_UNKNOWN and becomes useless on Linux. The Omoton KB066 is a pretty
popular keyboard, judging from its 29,058 reviews on Amazon at time of
writing, so let's account for its quirk to make it more usable.

By the way, it would be nice if we could automatically set fnmode to 0
for Omoton keyboards because they handle the Fn key internally and the
kernel's Fn key handling creates undesirable side effects such as making
F1 and F2 always Brightness Up and Brightness Down in fnmode=1 (the
default) or always F1 and F2 in fnmode=2. Unfortunately I don't think
there's a way to identify Bluetooth keyboards more specifically than the
HID product code which is obviously inaccurate. Users of Omoton
keyboards will just have to set fnmode to 0 manually to get full Fn key
functionality.

the faulty mode by bypassing the early returns if lizard mode is disabled.

363236d709 HID: ignore non-functional sensor in HP 5MP Camera
The HP 5MP Camera (USB ID 0408:5473) reports a HID sensor interface that
is not actually implemented. Attempting to access this non-functional
sensor via iio_info causes system hangs as runtime PM tries to wake up
an unresponsive sensor.

  [453] hid-sensor-hub 0003:0408:5473.0003: Report latency attributes: ffffffff:ffffffff
  [453] hid-sensor-hub 0003:0408:5473.0003: common attributes: 5:1, 2:1, 3:1 ffffffff:ffffffff

Add this device to the HID ignore list since the sensor interface is
non-functional by design and should not be exposed to userspace.

a5a056c8d2 HID: intel-thc: fix CONFIG_HID dependency
In drivers/hid/, most drivers depend on CONFIG_HID, while a couple of the
drivers in subdirectories instead depend on CONFIG_HID_SUPPORT and use
'select HID'. With the newly added INTEL_THC_HID, this causes a build
warning for a circular dependency:

WARNING: unmet direct dependencies detected for HID
  Depends on [m]: HID_SUPPORT [=y] && INPUT [=m]
  Selected by [y]:
  - INTEL_THC_HID [=y] && HID_SUPPORT [=y] && X86_64 [=y] && PCI [=y] && ACPI [=y]

  - PANTHERLORD_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_PANTHERLORD [=m]

It's better to be consistent and always use 'depends on HID' for HID
drivers. The notable exception here is USB_KBD/USB_MOUSE, which are
alternative implementations that do not depend on the HID subsystem.

Do this by extending the "if HID" section below, which means that a few
of the duplicate "depends on HID" and "depends on INPUT" statements
can be removed in the process.

52572cde8b HID: lenovo: select CONFIG_ACPI_PLATFORM_PROFILE
A previous patch tried to fix this link failure:

x86_64-linux-ld: drivers/hid/hid-lenovo.o: in function `lenovo_raw_event':
hid-lenovo.c:(.text+0x22c): undefined reference to `platform_profile_cycle'

but got it wrong in three ways:

 - the link failure still exists with CONFIG_ACPI_PLATFORM_PROFILE=m
   when hid-lenovo is built-in

 - There is no way to manually enable CONFIG_ACPI_PLATFORM_PROFILE, as
   it is intended to be selected by its users.

Remove the broken #if check again and instead select the symbol like
the other users do. This requires adding a dependency on CONFIG_ACPI.

7e0d1cff12 HID: intel-ish-hid: Send clock sync message immediately after reset
The ISH driver performs a clock sync with the firmware once at system
startup and then every 20 seconds. If a firmware reset occurs right
after a clock sync, the driver would wait 20 seconds before performing
another clock sync with the firmware. This is particularly problematic
with the introduction of the "load firmware from host" feature, where
the driver performs a clock sync with the bootloader and then has to
wait 20 seconds before syncing with the main firmware.

This patch clears prev_sync immediately upon receiving an IPC reset,
so that the main firmware and driver will perform a clock sync
immediately after completing the IPC handshake.

4b54ae6919 HID: intel-ish-hid: fix the length of MNG_SYNC_FW_CLOCK in doorbell
The timestamps in the Firmware log and HID sensor samples are incorrect.
They show 1970-01-01 because the current IPC driver only uses the first
8 bytes of bootup time when synchronizing time with the firmware. The
firmware converts the bootup time to UTC time, which results in the
display of 1970-01-01.

In write_ipc_from_queue(), when sending the MNG_SYNC_FW_CLOCK message,
the clock is updated according to the definition of ipc_time_update_msg.
However, in _ish_sync_fw_clock(), the message length is specified as the
size of uint64_t when building the doorbell. As a result, the firmware
only receives the first 8 bytes of struct ipc_time_update_msg.
This patch corrects the length in the doorbell to ensure the entire
ipc_time_update_msg is sent, fixing the timestamp issue.

   - Fix .probe() error path cleanup in the ACPI fan driver to avoid

   - Constify 'struct bin_attribute' in some places in the ACPI
     subsystem and mark it as __ro_after_init in one place to prevent
     binary blob attributes from being updated (Thomas Weißschuh)

   - Add empty stubs for several ACPI-related symbols so that they can

 "There's one big bit of work this time around, the addition of support
  for a greater range of MBQ access sizes to SoundWire devices together

  The MBQ register maps generally have variable register sizes, the
  variable regiseter size support allows them to be handled much more
  naturally within regmap with less open coding in drivers.

  The deferred read/write support avoids spurious errors when devices
  make use of a bus feature allowing them to indicate they're busy.

Pull networking updates from Paolo Abeni:
 "This is slightly smaller than usual, with the most interesting work
  being still around RTNL scope reduction.

  Core:

   - More core refactoring to reduce the RTNL lock contention, including
     preparatory work for the per-network namespace RTNL lock, replacing
     RTNL lock with a per device-one to protect NAPI-related net device
     data and moving synchronize_net() calls outside such lock.

   - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge
     and more specific TCP coverage.

   - Reduce network namespace tear-down time by removing per-subsystems
     synchronize_net() in tipc and sched.

   - Add flow label selector support for fib rules, allowing traffic
     redirection based on such header field.

  Netfilter:

   - Do not remove netdev basechain when last device is gone, allowing
     netdev basechains without devices.

   - Revisit the flowtable teardown strategy, dealing better with fin,
     reset and re-open events.

   - Scale-up IP-vs connection dumping by avoiding linear search on each
     restart.

  Protocols:

   - A significant XDP socket refactor, consolidating and optimizing
     several helpers into the core

   - Better scaling of ICMP rate-limiting, by removing false-sharing in
     inet peers handling.

   - Introduces netlink notifications for multicast IPv4 and IPv6
     address changes.

   - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
     aggregation and fragmentation of the inner IP.

   - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
     avoid local port exhaustion issues when the average connection
     lifetime is very short.

   - Support updating keys (re-keying) for connections using kernel TLS
     (for TLS 1.3 only).

   - Support ipv4-mapped ipv6 address clients in smc-r v2.

   - Add support for jumbo data packet transmission in RxRPC sockets,
     gluing multiple data packets in a single UDP packet.

   - Support RxRPC RACK-TLP to manage packet loss and retransmission in
     conjunction with the congestion control algorithm.

  Driver API:

   - Introduce a unified and structured interface for reporting PHY
     statistics, exposing consistent data across different H/W via
     ethtool.

   - Make timestamping selectable, allow the user to select the desired
     hwtstamp provider (PHY or MAC) administratively.

   - Add support for configuring a header-data-split threshold (HDS)
     value via ethtool, to deal with partial or buggy H/W
     implementation.

   - Consolidate DSA drivers Energy Efficiency Ethernet support.

   - Add EEE management to phylink, making use of the phylib
     implementation.

   - Add phylib support for in-band capabilities negotiation.

   - Simplify how phylib-enabled mac drivers expose the supported
     interfaces.

  Tests and tooling:

   - Make the YNL tool package-friendly to make it easier to deploy it
     separately from the kernel.

   - Increase TCP selftest coverage importing several packetdrill
     test-cases.

   - Regenerate the ethtool uapi header from the YNL spec, to ease
     maintenance and future development.

   - Add YNL support for decoding the link types used in net self-tests,
     allowing a single build to run both net and drivers/net.

  Drivers:

   - Ethernet high-speed NICs:
      - nVidia/Mellanox (mlx5):
         - add cross E-Switch QoS support
         - add SW Steering support for ConnectX-8

5f537664e7 cachestat: fix page cache statistics permission checking
When the 'cachestat()' system call was added in commit cf264e1329
("cachestat: implement cachestat syscall"), it was meant to be a much
more convenient (and performant) version of mincore() that didn't need
mapping things into the user virtual address space in order to work.

But it ended up missing the "check for writability or ownership" fix for
mincore(), done in commit 134fca9063 ("mm/mincore.c: make mincore()
more conservative").

This just adds equivalent logic to 'cachestat()', modified for the file
context (rather than vma).
