d53c3eaaef ARM: SoC devicetree changes for 6.4
The devicetree changes overall are again dominated by the Qualcomm
 Snapdragon platform that weighs in at over 300 changesets, but there
 are many updates across other platforms as well, notably Mediatek, NXP,
 Rockchips, Renesas, TI, Samsung and ST Microelectronics. These all
 add new features for existing machines, as well as new machines and
 SoCs.
 
 The newly added SoCs are:
 
  - Allwinner T113-s, an Cortex-A7 based variant of the RISC-V
    based D1 chip.
 
  - StarFive JH7110, a RISC-V SoC based on the Sifive U74 core
    like its JH7100 predecessor, but with additional CPU cores
    and a GPU.
 
  - Apple M2 as used in current Macbook Air/Pro and Mac Mini
    gets added, with comparable support as its M1 predecessor.
 
  - Unisoc UMS512 (Tiger T610) is a midrange smartphone SoC
 
  - Qualcomm IPQ5332 and IPQ9574 are Wi-Fi 7 networking SoCs,
    based on the Cortex-A53 and Cortex-A73 cores, respectively.
 
  - Qualcomm sa8775p is an automotive SoC derived from the
    Snapdragon family.
 
 Including the initial board support for the added SoC platforms,
 there are 52 new machines. The largest group are 19 boards
 industrial embedded boards based on the NXP i.MX6 (32-bit)
 and i.MX8 (64-bit) families.
 
 Others include:
 
  - Two boards based on the Allwinner f1c200s ultra-low-cost chip
 
  - Three "Banana Pi" variants based on the Amlogic g12b
    (A311D, S922X) SoC.
 
  - The Gl.Inet mv1000 router based on Marvell Armada 3720
 
  - A Wifi/LTE Dongle based on Qualcomm msm8916
 
  - Two robotics boards based on Qualcomm QRB chips
 
  - Three Snapdragon based phones made by Xiaomi
 
  - Five developments boards based on various Rockchip SoCs,
    including the rk3588s-khadas-edge2 and a few NanoPi
    models
 
  - The AM625 Beagleplay industrial SBC
 
 Another 14 machines get removed: both boards for the obsolete "oxnas"
 platform, three boards for the Renesas r8a77950 SoC that were only for
 pre-production chips, and various chromebook models based on the Qualcomm
 Sc7180 "trogdor" design that were never part of products.

e7989789c6 Timers and timekeeping updates:
- Improve the VDSO build time checks to cover all dynamic relocations
 
     VDSO does not allow dynamic relcations, but the build time check is
     incomplete and fragile.
 
     It's based on architectures specifying the relocation types to search
     for and does not handle R_*_NONE relocation entries correctly.
     R_*_NONE relocations are injected by some GNU ld variants if they fail
     to determine the exact .rel[a]/dyn_size to cover trailing zeros.
     R_*_NONE relocations must be ignored by dynamic loaders, so they
     should be ignored in the build time check too.
 
     Remove the architecture specific relocation types to check for and
     validate strictly that no other relocations than R_*_NONE end up
     in the VSDO .so file.
 
   - Prefer signal delivery to the current thread for
     CLOCK_PROCESS_CPUTIME_ID based posix-timers
 
     Such timers prefer to deliver the signal to the main thread of a
     process even if the context in which the timer expires is the current
     task. This has the downside that it might wake up an idle thread.
 
     As there is no requirement or guarantee that the signal has to be
     delivered to the main thread, avoid this by preferring the current
     task if it is part of the thread group which shares sighand.
 
     This not only avoids waking idle threads, it also distributes the
     signal delivery in case of multiple timers firing in the context
     of different threads close to each other better.
 
   - Align the tick period properly (again)
 
     For a long time the tick was starting at CLOCK_MONOTONIC zero, which
     allowed users space applications to either align with the tick or to
     place a periodic computation so that it does not interfere with the
     tick. The alignement of the tick period was more by chance than by
     intention as the tick is set up before a high resolution clocksource is
     installed, i.e. timekeeping is still tick based and the tick period
     advances from there.
 
     The early enablement of sched_clock() broke this alignement as the time
     accumulated by sched_clock() is taken into account when timekeeping is
     initialized. So the base value now(CLOCK_MONOTONIC) is not longer a
     multiple of tick periods, which breaks applications which relied on
     that behaviour.
 
     Cure this by aligning the tick starting point to the next multiple of
     tick periods, i.e 1000ms/CONFIG_HZ.
 
  - A set of NOHZ fixes and enhancements
 
    - Cure the concurrent writer race for idle and IO sleeptime statistics
 
      The statitic values which are exposed via /proc/stat are updated from
      the CPU local idle exit and remotely by cpufreq, but that happens
      without any form of serialization. As a consequence sleeptimes can be
      accounted twice or worse.
 
      Prevent this by restricting the accumulation writeback to the CPU
      local idle exit and let the remote access compute the accumulated
      value.
 
    - Protect idle/iowait sleep time with a sequence count
 
      Reading idle/iowait sleep time, e.g. from /proc/stat, can race with
      idle exit updates. As a consequence the readout may result in random
      and potentially going backwards values.
 
      Protect this by a sequence count, which fixes the idle time
      statistics issue, but cannot fix the iowait time problem because
      iowait time accounting races with remote wake ups decrementing the
      remote runqueues nr_iowait counter. The latter is impossible to fix,
      so the only way to deal with that is to document it properly and to
      remove the assertion in the selftest which triggers occasionally due
      to that.
 
    - Restructure struct tick_sched for better cache layout
 
    - Some small cleanups and a better cache layout for struct tick_sched
 
  - Implement the missing timer_wait_running() callback for POSIX CPU timers
 
    For unknown reason the introduction of the timer_wait_running() callback
    missed to fixup posix CPU timers, which went unnoticed for almost four
    years.
 
    While initially only targeted to prevent livelocks between a timer
    deletion and the timer expiry function on PREEMPT_RT enabled kernels, it
    turned out that fixing this for mainline is not as trivial as just
    implementing a stub similar to the hrtimer/timer callbacks.
 
    The reason is that for CONFIG_POSIX_CPU_TIMERS_TASK_WORK enabled systems
    there is a livelock issue independent of RT.
 
    CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y moves the expiry of POSIX CPU timers
    out from hard interrupt context to task work, which is handled before
    returning to user space or to a VM. The expiry mechanism moves the
    expired timers to a stack local list head with sighand lock held. Once
    sighand is dropped the task can be preempted and a task which wants to
    delete a timer will spin-wait until the expiry task is scheduled back
    in. In the worst case this will end up in a livelock when the preempting
    task and the expiry task are pinned on the same CPU.
 
    The timer wheel has a timer_wait_running() mechanism for RT, which uses
    a per CPU timer-base expiry lock which is held by the expiry code and the
    task waiting for the timer function to complete blocks on that lock.
 
    This does not work in the same way for posix CPU timers as there is no
    timer base and expiry for process wide timers can run on any task
    belonging to that process, but the concept of waiting on an expiry lock
    can be used too in a slightly different way.
 
    Add a per task mutex to struct posix_cputimers_work, let the expiry task
    hold it accross the expiry function and let the deleting task which
    waits for the expiry to complete block on the mutex.
 
    In the non-contended case this results in an extra mutex_lock()/unlock()
    pair on both sides.
 
    This avoids spin-waiting on a task which is scheduled out, prevents the
    livelock and cures the problem for RT and !RT systems.

Merge tag 'v6.4/kernel.user_worker' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull user work thread updates from Christian Brauner:
 "This contains the work generalizing the ability to create a kernel
  worker from a userspace process.

  Such user workers will run with the same credentials as the userspace
  process they were created from providing stronger security and
  accounting guarantees than the traditional override_creds() approach
  ever could've hoped for.

  The original work was heavily based and optimzed for the needs of
  io_uring which was the first user. However, as it quickly turned out
  the ability to create user workers inherting properties from a
  userspace process is generally useful.

  The vhost subsystem currently creates workers using the kthread api.
  The consequences of using the kthread api are that RLIMITs don't work
  correctly as they are inherited from khtreadd. This leads to bugs
  where more workers are created than would be allowed by the RLIMITs of
  the userspace process in lieu of which workers are created.

  Problems like this disappear with user workers created from the
  userspace processes for which they perform the work. In addition,
  providing this api allows vhost to remove additional complexity. For
  example, cgroup and mm sharing will just work out of the box with user
  workers based on the relevant userspace process instead of manually
  ensuring the correct cgroup and mm contexts are used.

  So the vhost subsystem should simply be made to use the same mechanism
  as io_uring. To this end the original mechanism used for
  create_io_thread() is generalized into user workers:

   - Introduce PF_USER_WORKER as a generic indicator that a given task
     is a user worker, i.e., a kernel task that was created from a
     userspace process. Now a PF_IO_WORKER thread is just a specialized
     version of PF_USER_WORKER. So io_uring io workers raise both flags.

   - Make copy_process() available to core kernel code

   - Extend struct kernel_clone_args with the following bitfields
     allowing to indicate to copy_process():
       - to create a user worker (raise PF_USER_WORKER)
       - to not inherit any files from the userspace process
       - to ignore signals

  After all generic changes are in place the vhost subsystem implements
  a new dedicated vhost api based on user workers. Finally, vhost is
  switched to rely on the new api moving it off of kthreads.

  Thanks to Mike for sticking it out and making it through this rather
  arduous journey"

Merge tag 'selinux-pr-20230420' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:

 - Stop passing the 'selinux_state' pointers as function arguments

   As discussed during the end of the last development cycle, passing a
   selinux_state pointer through the SELinux code has a noticeable
   impact on performance, and with the current code it is not strictly
   necessary.

   This simplifies things by referring directly to the single
   selinux_state global variable which should help improve SELinux
   performance.

 - Uninline the unlikely portions of avc_has_perm_noaudit()

   This change was also based on a discussion from the last development
   cycle, and is heavily based on an initial proof of concept patch from
   you. The core issue was that avc_has_perm_noaudit() was not able to
   be inlined, as intended, due to its size. We solved this issue by
   extracting the less frequently hit portions of avc_has_perm_noaudit()
   into a separate function, reducing the size of avc_has_perm_noaudit()
   to the point where the compiler began inlining the function. We also
   took the opportunity to clean up some ugly RCU locking in the code
   that became uglier with the change.

 - Remove the runtime disable functionality

   After several years of work by the userspace and distro folks, we are
   finally in a place where we feel comfortable removing the runtime
   disable functionality which we initially deprecated at the start of
   2020.

   There is plenty of information in the kernel's deprecation (now
   removal) notice, but the main motivation was to be able to safely
   mark the LSM hook structures as '__ro_after_init'.

   LWN also wrote a good summary of the deprecation this morning which
   offers a more detailed history:

        https://lwn.net/SubscriberLink/927463/dcfa0d4ed2872f03

 - Remove the checkreqprot functionality

   The original checkreqprot deprecation notice stated that the removal
   would happen no sooner than June 2021, which means this falls hard
   into the "better late than never" bucket.

   The Kconfig and deprecation notice has more detail on this setting,
   but the basic idea is that we want to ensure that the SELinux policy
   allows for the memory protections actually applied by the kernel, and
   not those requested by the process.

   While we haven't found anyone running a supported distro that is
   affected by this deprecation/removal, anyone who is affected would
   only need to update their policy to reflect the reality of their
   applications' mapping protections.

 - Minor Makefile improvements

   Some minor Makefile improvements to correct some dependency issues
   likely only ever seen by SELinux developers. I expect we will have at
   least one more tweak to the Makefile during the next merge window,
   but it didn't quite make the cutoff this time around.

689ca16e52 Bluetooth: NXP: Add protocol support for NXP Bluetooth chipsets
This adds a driver based on serdev driver for the NXP BT serial protocol
based on running H:4, which can enable the built-in Bluetooth device
inside an NXP BT chip.

This driver has Power Save feature that will put the chip into sleep state
whenever there is no activity for 2000ms, and will be woken up when any
activity is to be initiated over UART.

This driver enables the power save feature by default by sending the vendor
specific commands to the chip during setup.

During setup, the driver checks if a FW is already running on the chip
by waiting for the bootloader signature, and downloads device specific FW
file into the chip over UART if bootloader signature is received..

f3948874c3 MAINTAINERS: replace maintainer of FireWire subsystem
In the last few years, I have reviewed patches for FireWire subsystem and
requested sound subsystem maintainer to sent them to mainline, since
FireWire subsystem maintainer has been long absent. This situation is not
preferable since we have some user of sound hardware in IEEE 1394 bus.

I will stand for the maintainer, and work for FireWire core functions and
1394 OHCI driver, as well as sound drivers. This commit replaces the
corresponding entry.

As you know, IEEE 1394 is enough legacy. I would like to schedule the end
of my work in the subsystem. My effort will last next 6 years. In 2026, I
will start strong announcement for users to migrate their work load from
IEEE 1394 bus (e.g. by purchasing alternative devices in USB and hardening
system for them), then in 2029 let me resign the maintainer and close
Linux 1394 project.

My current work focuses on real time data (sampling data) transmission
protocol in packet-oriented communication, thus I would provide less help
to implementations for the other type of protocol; i.e. IPv4/IPv6 over
IEEE 1394 bus (firewire-net), SCSI transport protocol over IEEE 1394 bus
(firewire-sbp2) and iSCSI target (sbp-target).

If receiving few objections from developers, I will start my work to send
fixes for v6.3 prepatch, and PR for future v6.4 or later. I'm pleased if
getting any help until the end.

11841c52fa MAINTAINERS: make me a reviewer of VIRTIO CORE AND NET DRIVERS
First of all, I personally love open source, linux and virtio. I have
also participated in community work such as virtio for a long time.

I think I am familiar enough with virtio/virtio-net and is adequate as a
reviewer.

Every time there is some patch/bug, I wish I can get pinged
and I will feedback on that.

For me personally, being a reviewer is an honor and a responsibility,
and it also makes it easier for me to participate in virtio-related
work. And I will spend more time reviewing virtio patch. Better advance
virtio development

I had some contributions to virtio/virtio-net and some support for it.

* per-queue reset
* virtio-net xdp
* some bug fix
* ......

I make a humble request to grant the reviewer role for the virtio core
and net drivers.

b0cf5d5021 MAINTAINERS: add Benno Lossin as Rust reviewer
Benno has been involved with the Rust for Linux project for
the better part of a year now. He has been working on solving
the safe pinned initialization problem [1], which resulted in
the pin-init API patch series [2] that allows to reduce the
need for `unsafe` code in the kernel. He is also working on
the field projection RFC for Rust [3] to bring pin-init as
a language feature.

His expertise with the language will be very useful to have
around in the future if Rust grows within the kernel, thus
add him to the `RUST` entry as reviewer.

4daa669efc kernel/configs: Drop Android config fragments
In the old days where each device had a custom kernel, the
android config fragments were useful to provide the required
and reccomended options expected by userland.

However, these days devices are expected to use the GKI kernel,
so these config fragments no longer needed, and out of date, so
they seem to only cause confusion.

So lets drop them. If folks are curious what configs are
expected by the Android environment, check out the gki_defconfig
file in the latest android common kernel tree.

3b3009ea8a net/handshake: Create a NETLINK service for handling handshake requests
When a kernel consumer needs a transport layer security session, it
first needs a handshake to negotiate and establish a session. This
negotiation can be done in user space via one of the several
existing library implementations, or it can be done in the kernel.

No in-kernel handshake implementations yet exist. In their absence,
we add a netlink service that can:

a. Notify a user space daemon that a handshake is needed.

b. Once notified, the daemon calls the kernel back via this
   netlink service to get the handshake parameters, including an
   open socket on which to establish the session.

c. Once the handshake is complete, the daemon reports the
   session status and other information via a second netlink
   operation. This operation marks that it is safe for the
   kernel to use the open socket and the security session
   established there.

The notification service uses a multicast group. Each handshake
mechanism (eg, tlshd) adopts its own group number so that the
handshake services are completely independent of one another. The
kernel can then tell via netlink_has_listeners() whether a handshake
service is active and prepared to handle a handshake request.

A new netlink operation, ACCEPT, acts like accept(2) in that it
instantiates a file descriptor in the user space daemon's fd table.
If this operation is successful, the reply carries the fd number,
which can be treated as an open and ready file descriptor.

While user space is performing the handshake, the kernel keeps its
muddy paws off the open socket. A second new netlink operation,
DONE, indicates that the user space daemon is finished with the
socket and it is safe for the kernel to use again. The operation
also indicates whether a session was established successfully.

cf21f328fc media: nxp: Add i.MX8 ISI driver
The Image Sensing Interface (ISI) combines image processing pipelines
with DMA engines to process and capture frames originating from a
variety of sources. The inputs to the ISI go through Pixel Link
interfaces, and their number and nature is SoC-dependent. They cover
both capture interfaces (MIPI CSI-2 RX, HDMI RX) and memory inputs.

95a9ea8a13 media: i2c: Drop unused mt9t001 camera sensor driver
The mt9t001 camera sensor driver doesn't support DT and relies on
platform data. No board file has ever provided platform data for that
device. The driver has thus never been used in the mainline kernel since
its introduction in v3.2. Drop it.
