 - Continued refactoring around ASoC DAI links and the ordering of
   trigger callbacks
 - PCM ABI extension for better drain support
 
 ASoC Drivers:
 - Conversions of many drivers to use maple tree based caches
 - Everlasting improvement works on ASoC Intel drivers
 - Compressed audio support for Qualcomm
 - Support for AMD SoundWire, Analog Devices SSM3515, Google Chameleon,

Linus Torvalds
3a8a670eee Networking changes for 6.5. 
Core
 ----
 
  - Rework the sendpage & splice implementations. Instead of feeding
    data into sockets page by page extend sendmsg handlers to support
    taking a reference on the data, controlled by a new flag called
    MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
    to invoke an additional callback instead of trying to predict what
    the right combination of MORE/NOTLAST flags is.
    Remove the MSG_SENDPAGE_NOTLAST flag completely.
 
  - Implement SCM_PIDFD, a new type of CMSG type analogous to
    SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
 
  - Enable socket busy polling with CONFIG_RT.
 
  - Improve reliability and efficiency of reporting for ref_tracker.
 
  - Auto-generate a user space C library for various Netlink families.
 
 Protocols
 ---------
 
  - Allow TCP to shrink the advertised window when necessary, prevent
    sk_rcvbuf auto-tuning from growing the window all the way up to
    tcp_rmem[2].
 
  - Use per-VMA locking for "page-flipping" TCP receive zerocopy.
 
  - Prepare TCP for device-to-device data transfers, by making sure
    that payloads are always attached to skbs as page frags.
 
  - Make the backoff time for the first N TCP SYN retransmissions
    linear. Exponential backoff is unnecessarily conservative.
 
  - Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
 
  - Avoid waking up applications using TLS sockets until we have
    a full record.
 
  - Allow using kernel memory for protocol ioctl callbacks, paving
    the way to issuing ioctls over io_uring.
 
  - Add nolocalbypass option to VxLAN, forcing packets to be fully
    encapsulated even if they are destined for a local IP address.
 
  - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
    in-kernel ECMP implementation (e.g. Open vSwitch) select the same
    link for all packets. Support L4 symmetric hashing in Open vSwitch.
 
  - PPPoE: make number of hash bits configurable.
 
  - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
    (ipconfig).
 
  - Add layer 2 miss indication and filtering, allowing higher layers
    (e.g. ACL filters) to make forwarding decisions based on whether
    packet matched forwarding state in lower devices (bridge).
 
  - Support matching on Connectivity Fault Management (CFM) packets.
 
  - Hide the "link becomes ready" IPv6 messages by demoting their
    printk level to debug.
 
  - HSR: don't enable promiscuous mode if device offloads the proto.
 
  - Support active scanning in IEEE 802.15.4.
 
  - Continue work on Multi-Link Operation for WiFi 7.
 
 BPF
 ---
 
  - Add precision propagation for subprogs and callbacks. This allows
    maintaining verification efficiency when subprograms are used,
    or in fact passing the verifier at all for complex programs,
    especially those using open-coded iterators.
 
  - Improve BPF's {g,s}setsockopt() length handling. Previously BPF
    assumed the length is always equal to the amount of written data.
    But some protos allow passing a NULL buffer to discover what
    the output buffer *should* be, without writing anything.
 
  - Accept dynptr memory as memory arguments passed to helpers.
 
  - Add routing table ID to bpf_fib_lookup BPF helper.
 
  - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
 
  - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
    maps as read-only).
 
  - Show target_{obj,btf}_id in tracing link fdinfo.
 
  - Addition of several new kfuncs (most of the names are self-explanatory):
    - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
      bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
      and bpf_dynptr_clone().
    - bpf_task_under_cgroup()
    - bpf_sock_destroy() - force closing sockets
    - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
 
 Netfilter
 ---------
 
  - Relax set/map validation checks in nf_tables. Allow checking
    presence of an entry in a map without using the value.
 
  - Increase ip_vs_conn_tab_bits range for 64BIT builds.
 
  - Allow updating size of a set.
 
  - Improve NAT tuple selection when connection is closing.
 
 Driver API
 ----------
 
  - Integrate netdev with LED subsystem, to allow configuring HW
    "offloaded" blinking of LEDs based on link state and activity
    (i.e. packets coming in and out).
 
  - Support configuring rate selection pins of SFP modules.
 
  - Factor Clause 73 auto-negotiation code out of the drivers, provide
    common helper routines.
 
  - Add more fool-proof helpers for managing lifetime of MDIO devices
    associated with the PCS layer.
 
  - Allow drivers to report advanced statistics related to Time Aware
    scheduler offload (taprio).
 
  - Allow opting out of VF statistics in link dump, to allow more VFs
    to fit into the message.
 
  - Split devlink instance and devlink port operations.

One small core feature this time around but mostly driver improvements
 and additions for SPI:
 
  - Add support for controlling the idle state of MOSI, some systems can
    support this and depending on the system integration may need it to
    avoid glitching in some situations.
  - Support for polling mode in the S3C64xx driver and DMA on the
    Qualcomm QSPI driver.
  - Support for several Allwinner SoCs, AMD Pensando Elba, Intel Mount

Pull hardening updates from Kees Cook:
 "There are three areas of note:

  A bunch of strlcpy()->strscpy() conversions ended up living in my tree
  since they were either Acked by maintainers for me to carry, or got
  ignored for multiple weeks (and were trivial changes).

  The compiler option '-fstrict-flex-arrays=3' has been enabled
  globally, and has been in -next for the entire devel cycle. This
  changes compiler diagnostics (though mainly just -Warray-bounds which
  is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_
  coverage. In other words, there are no new restrictions, just
  potentially new warnings. Any new FORTIFY warnings we've seen have
  been fixed (usually in their respective subsystem trees). For more
  details, see commit df8fc4e934c12b.

  The under-development compiler attribute __counted_by has been added
  so that we can start annotating flexible array members with their
  associated structure member that tracks the count of flexible array
  elements at run-time. It is possible (likely?) that the exact syntax
  of the attribute will change before it is finalized, but GCC and Clang
  are working together to sort it out. Any changes can be made to the
  macro while we continue to add annotations.

  As an example of that last case, I have a treewide commit waiting with
  such annotations found via Coccinelle:

    https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b

  Also see commit dd06e72e68bcb4 for more details.

Merge tag 'lsm-pr-20230626' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull lsm updates from Paul Moore:

 - A SafeSetID patch to correct what appears to be a cut-n-paste typo in
   the code causing a UID to be printed where a GID was desired.

   This is coming via the LSM tree because we haven't been able to get a
   response from the SafeSetID maintainer (Micah Morton) in several
   months. Hopefully we are able to get in touch with Micah, but until
   we do I'm going to pick them up in the LSM tree.

 - A small fix to the reiserfs LSM xattr code.

   We're continuing to work through some issues with the reiserfs code
   as we try to fixup the LSM xattr handling, but in the process we're
   uncovering some ugly problems in reiserfs and we may just end up
   removing the LSM xattr support in reiserfs prior to reiserfs'
   removal.

   For better or worse, this shouldn't impact any of the reiserfs users,
   as we discovered that LSM xattrs on reiserfs were completely broken,
   meaning no one is currently using the combo of reiserfs and a file
   labeling LSM.

 - A tweak to how the cap_user_data_t struct/typedef is declared in the
   header file to appease the Sparse gods.

 - In the process of trying to sort out the SafeSetID lost-maintainer
   problem I realized that I needed to update the labeled networking
   entry to "Supported".

 - Minor comment/documentation and spelling fixes.

6a46676994 s390 updates for 6.5 merge window 
- Fix the style of protected key API driver source: use
   x-mas tree for all local variable declarations.
 
 - Rework protected key API driver to not use the struct
   pkey_protkey and pkey_clrkey anymore. Both structures
   have a fixed size buffer, but with the support of ECC
   protected key these buffers are not big enough. Use
   dynamic buffers internally and transparently for
   userspace.
 
 - Add support for a new 'non CCA clear key token' with
   ECC clear keys supported: ECC P256, ECC P384, ECC P521,
   ECC ED25519 and ECC ED448. This makes it possible to
   derive a protected key from the ECC clear key input via
   PKEY_KBLOB2PROTK3 ioctl, while currently the only way
   to derive is via PCKMO instruction.
 
 - The s390 PMU of PAI crypto and extension 1 NNPA counters
   use atomic_t for reference counting. Replace this with
   the proper data type refcount_t.
 
 - Select ARCH_SUPPORTS_INT128, but limit this to clang for
   now, since gcc generates inefficient code, which may lead
   to stack overflows.
 
 - Replace one-element array with flexible-array member in
   struct vfio_ccw_parent and refactor the rest of the code
   accordingly. Also, prefer struct_size() over sizeof() open-
   coded versions.
 
 - Introduce OS_INFO_FLAGS_ENTRY pointing to a flags field and
   OS_INFO_FLAG_REIPL_CLEAR flag that informs a dumper whether
   the system memory should be cleared or not once dumped.
 
 - Fix a hang when a user attempts to remove a VFIO-AP mediated
   device attached to a guest: add VFIO_DEVICE_GET_IRQ_INFO and
   VFIO_DEVICE_SET_IRQS IOCTLs and wire up the VFIO bus driver
   callback to request a release of the device.
 
 - Fix calculation for R_390_GOTENT relocations for modules.
 
 - Allow any user space process with CAP_PERFMON capability
   read and display the CPU Measurement facility counter sets.
 
 - Rework large statically-defined per-CPU cpu_cf_events data
   structure and replace it with dynamically allocated structures
   created when a perf_event_open() system call is invoked or
   /dev/hwctr device is accessed.

bc6cb4d5bc Locking changes for v6.5: 
- Introduce cmpxchg128() -- aka. the demise of cmpxchg_double().
 
   The cmpxchg128() family of functions is basically & functionally
   the same as cmpxchg_double(), but with a saner interface: instead
   of a 6-parameter horror that forced u128 - u64/u64-halves layout
   details on the interface and exposed users to complexity,
   fragility & bugs, use a natural 3-parameter interface with u128 types.
 
 - Restructure the generated atomic headers, and add
   kerneldoc comments for all of the generic atomic{,64,_long}_t
   operations. Generated definitions are much cleaner now,
   and come with documentation.
 
 - Implement lock_set_cmp_fn() on lockdep, for defining an ordering
   when taking multiple locks of the same type. This gets rid of
   one use of lockdep_set_novalidate_class() in the bcache code.
 
 - Fix raw_cpu_generic_try_cmpxchg() bug due to an unintended
   variable shadowing generating garbage code on Clang on certain
   ARM builds.

====================
Netfilter/IPVS updates for net-next

1) Allow slightly larger IPVS connection table size from Kconfig for
   64-bit arch, from Abhijeet Rastogi.

2) Since IPVS connection table might be larger than 2^20 after previous
   patch, allow to limit it depending on the available memory.
   Moreover, use kvmalloc. From Julian Anastasov.

3) Do not rebuild VLAN header in nft_payload when matching source and
   destination MAC address.

4) Remove nested rcu read lock side in ip_set_test(), from Florian Westphal.

5) Allow to update set size, also from Florian.

6) Improve NAT tuple selection when connection is closing,
   from Florian Westphal.

7) Support for resetting set element stateful expression, from Phil Sutter.

Merge tag 'v6.5/vfs.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs mount updates from Christian Brauner:
 "This contains the work to extend move_mount() to allow adding a mount
  beneath the topmost mount of a mount stack.

  There are two LWN articles about this. One covers the original patch
  series in [1]. The other in [2] summarizes the session and roughly the
  discussion between Al and me at LSFMM. The second article also goes
  into some good questions from attendees.

  Since all details are found in the relevant commit with a technical
  dive into semantics and locking at the end I'm only adding the
  motivation and core functionality for this from commit message and
  leave out the invasive details. The code is also heavily commented and
  annotated as well which was explicitly requested.

  TL;DR:

    > mount -t ext4 /dev/sda /mnt
      |
      └─/mnt    /dev/sda    ext4

    > mount --beneath -t xfs /dev/sdb /mnt
      |
      └─/mnt    /dev/sdb    xfs
        └─/mnt  /dev/sda    ext4

    > umount /mnt
      |
      └─/mnt    /dev/sdb    xfs

  The longer motivation is that various distributions are adding or are
  in the process of adding support for system extensions and in the
  future configuration extensions through various tools. A more detailed
  explanation on system and configuration extensions can be found on the
  manpage which is listed below at [3].

  System extension images may – dynamically at runtime — extend the
  /usr/ and /opt/ directory hierarchies with additional files. This is
  particularly useful on immutable system images where a /usr/ and/or
  /opt/ hierarchy residing on a read-only file system shall be extended
  temporarily at runtime without making any persistent modifications.

  When one or more system extension images are activated, their /usr/
  and /opt/ hierarchies are combined via overlayfs with the same
  hierarchies of the host OS, and the host /usr/ and /opt/ overmounted
  with it ("merging"). When they are deactivated, the mount point is
  disassembled — again revealing the unmodified original host version of
  the hierarchy ("unmerging"). Merging thus makes the extension's
  resources suddenly appear below the /usr/ and /opt/ hierarchies as if
  they were included in the base OS image itself. Unmerging makes them
  disappear again, leaving in place only the files that were shipped
  with the base OS image itself.

  System configuration images are similar but operate on directories
  containing system or service configuration.

  On nearly all modern distributions mount propagation plays a crucial
  role and the rootfs of the OS is a shared mount in a peer group
  (usually with peer group id 1):

     TARGET  SOURCE  FSTYPE  PROPAGATION  MNT_ID  PARENT_ID
     /       /       ext4    shared:1     29      1

  On such systems all services and containers run in a separate mount
  namespace and are pivot_root()ed into their rootfs. A separate mount
  namespace is almost always used as it is the minimal isolation
  mechanism services have. But usually they are even much more isolated
  up to the point where they almost become indistinguishable from
  containers.

  Mount propagation again plays a crucial role here. The rootfs of all
  these services is a slave mount to the peer group of the host rootfs.
  This is done so the service will receive mount propagation events from
  the host when certain files or directories are updated.

  In addition, the rootfs of each service, container, and sandbox is
  also a shared mount in its separate peer group:

     TARGET  SOURCE  FSTYPE  PROPAGATION         MNT_ID  PARENT_ID
     /       /       ext4    shared:24 master:1  71      47

  For people not too familiar with mount propagation, the master:1 means
  that this is a slave mount to peer group 1. Which as one can see is
  the host rootfs as indicated by shared:1 above. The shared:24
  indicates that the service rootfs is a shared mount in a separate peer
  group with peer group id 24.

  A service may run other services. Such nested services will also have
  a rootfs mount that is a slave to the peer group of the outer service
  rootfs mount.

  For containers things are just slighly different. A container's rootfs
  isn't a slave to the service's or host rootfs' peer group. The rootfs
  mount of a container is simply a shared mount in its own peer group:

     TARGET                    SOURCE  FSTYPE  PROPAGATION  MNT_ID  PARENT_ID
     /home/ubuntu/debian-tree  /       ext4    shared:99    61      60

  So whereas services are isolated OS components a container is treated
  like a separate world and mount propagation into it is restricted to a
  single well known mount that is a slave to the peer group of the
  shared mount /run on the host:

     TARGET                  SOURCE              FSTYPE  PROPAGATION  MNT_ID  PARENT_ID
     /propagate/debian-tree  /run/host/incoming  tmpfs   master:5     71      68

  Here, the master:5 indicates that this mount is a slave to the peer
  group with peer group id 5. This allows to propagate mounts into the
  container and served as a workaround for not being able to insert
  mounts into mount namespaces directly. But the new mount api does
  support inserting mounts directly. For the interested reader the
  blogpost in [4] might be worth reading where I explain the old and the
  new approach to inserting mounts into mount namespaces.

  Containers of course, can themselves be run as services. They often
  run full systems themselves which means they again run services and
  containers with the exact same propagation settings explained above.

  The whole system is designed so that it can be easily updated,
  including all services in various fine-grained ways without having to
  enter every single service's mount namespace which would be
  prohibitively expensive. The mount propagation layout has been
  carefully chosen so it is possible to propagate updates for system
  extensions and configurations from the host into all services.

  The simplest model to update the whole system is to mount on top of
  /usr, /opt, or /etc on the host. The new mount on /usr, /opt, or /etc
  will then propagate into every service. This works cleanly the first
  time. However, when the system is updated multiple times it becomes
  necessary to unmount the first update on /opt, /usr, /etc and then
  propagate the new update. But this means, there's an interval where
  the old base system is accessible. This has to be avoided to protect
  against downgrade attacks.

  The vfs already exposes a mechanism to userspace whereby mounts can be
  mounted beneath an existing mount. Such mounts are internally referred
  to as "tucked". The patch series exposes the ability to mount beneath
  a top mount through the new MOVE_MOUNT_BENEATH flag for the
  move_mount() system call. This allows userspace to seamlessly upgrade
  mounts. After this series the only thing that will have changed is
  that mounting beneath an existing mount can be done explicitly instead
  of just implicitly.

  The crux is that the proposed mechanism already exists and that it is
  so powerful as to cover cases where mounts are supposed to be updated
  with new versions. Crucially, it offers an important flexibility.
  Namely that updates to a system may either be forced or can be delayed
  and the umount of the top mount be left to a service if it is a
  cooperative one"

Pull misc vfs updates from Christian Brauner:
 "Miscellaneous features, cleanups, and fixes for vfs and individual fs

  Features:

   - Use mode 0600 for file created by cachefilesd so it can be run by
     unprivileged users. This aligns them with directories which are
     already created with mode 0700 by cachefilesd

   - Reorder a few members in struct file to prevent some false sharing
     scenarios

   - Indicate that an eventfd is used a semaphore in the eventfd's
     fdinfo procfs file

   - Add a missing uapi header for eventfd exposing relevant uapi
     defines

   - Let the VFS protect transitions of a superblock from read-only to
     read-write in addition to the protection it already provides for
     transitions from read-write to read-only. Protecting read-only to
     read-write transitions allows filesystems such as ext4 to perform
     internal writes, keeping writers away until the transition is
     completed

  Cleanups:

   - Arnd removed the architecture specific arch_report_meminfo()
     prototypes and added a generic one into procfs.h. Note, we got a
     report about a warning in amdpgpu codepaths that suggested this was
     bisectable to this change but we concluded it was a false positive

   - Remove unused parameters from split_fs_names()

   - Rename put_and_unmap_page() to unmap_and_put_page() to let the name
     reflect the order of the cleanup operation that has to unmap before
     the actual put

   - Unexport buffer_check_dirty_writeback() as it is not used outside
     of block device aops

   - Stop allocating aio rings from highmem

   - Protecting read-{only,write} transitions in the VFS used open-coded
     barriers in various places. Replace them with proper little helpers
     and document both the helpers and all barrier interactions involved
     when transitioning between read-{only,write} states

   - Use flexible array members in old readdir codepaths

  Fixes:

   - Use the correct type __poll_t for epoll and eventfd

   - Replace all deprecated strlcpy() invocations, whose return value
     isn't checked with an equivalent strscpy() call

   - Fix some kernel-doc warnings in fs/open.c

   - Reduce the stack usage in jffs2's xattr codepaths finally getting
     rid of this: fs/jffs2/xattr.c:887:1: error: the frame size of 1088
     bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
     royally annoying compilation warning

   - Use __FMODE_NONOTIFY instead of FMODE_NONOTIFY where an int and not
     fmode_t is required to avoid fmode_t to integer degradation
     warnings

   - Create coredumps with O_WRONLY instead of O_RDWR. There's a long
     explanation in that commit how O_RDWR is actually a bug which we
     found out with the help of Linus and git archeology

   - Fix "no previous prototype" warnings in the pipe codepaths

   - Add overflow calculations for remap_verify_area() as a signed
     addition overflow could be triggered in xfstests

   - Fix a null pointer dereference in sysv

   - Use an unsigned variable for length calculations in jfs avoiding
     compilation warnings with gcc 13

   - Fix a dangling pipe pointer in the watch queue codepath

   - The legacy mount option parser provided as a fallback by the VFS
     for filesystems not yet converted to the new mount api did prefix
     the generated mount option string with a leading ',' causing issues
     for some filesystems

   - Fix a repeated word in a comment in fs.h

   - autofs: Update the ctime when mtime is updated as mandated by
     POSIX"

====================
pull-request: can-next 2023-06-22

The first patch is by Carsten Schmidt, targets the kvaser_usb driver
and adds len8_dlc support.

Marcel Hellwig's patch for the xilinx_can driver adds support for CAN
transceivers via the PHY framework.

Frank Jungclaus contributes 6+2 patches for the esd_usb driver in
preparation for the upcoming CAN-USB/3 support.

The 2 patches by Miquel Raynal for the sja1000 driver work around
overruns stalls on the Renesas SoCs.

The next 3 patches are by me and fix the coding style in the
rx-offload helper and in the m_can and ti_hecc driver.

Vincent Mailhol contributes 3 patches to fix and update the
calculation of the length of CAN frames on the wire.

Oliver Hartkopp's patch moves the CAN_RAW_FILTER_MAX definition into
the correct header.

The remaining 14 patches are by Jimmy Assarsson, target the
kvaser_pciefd driver and bring various updates and improvements.

492432074e mptcp: introduce MPTCP_FULL_INFO getsockopt 
Some user-space applications want to monitor the subflows utilization.

Dumping the per subflow tcp_info is not enough, as the PM could close
and re-create the subflows under-the-hood, fooling the accounting.
Even checking the src/dst addresses used by each subflow could not
be enough, because new subflows could re-use the same address/port of
the just closed one.

This patch introduces a new socket option, allow dumping all the relevant
information all-at-once (everything, everywhere...), in a consistent
manner.

38967f424b mptcp: track some aggregate data counters 
Currently there are no data transfer counters accounting for all
the subflows used by a given MPTCP socket. The user-space can compute
such figures aggregating the subflow info, but that is inaccurate
if any subflow is closed before the MPTCP socket itself.

Add the new counters in the MPTCP socket itself and expose them
via the existing diag and sockopt. While touching mptcp_diag_fill_info(),
acquire the relevant locks before fetching the msk data, to ensure
better data consistency

95a55437dc block: change all __u32 annotations to __be32 in affs_hardblocks.h 
The Amiga partition parser module uses signed int for partition sector
address and count, which will overflow for disks larger than 1 TB.

Use u64 as type for sector address and size to allow using disks up to
2 TB without LBD support, and disks larger than 2 TB with LBD. The RBD
format allows to specify disk sizes up to 2^128 bytes (though native
OS limitations reduce this somewhat, to max 2^68 bytes), so check for
u64 overflow carefully to protect against overflowing sector_t.

This bug was reported originally in 2012, and the fix was created by
the RDB author, Joanne Dow <jdow@earthlink.net>. A patch had been
discussed and reviewed on linux-m68k at that time but never officially
submitted (now resubmitted as patch 1 of this series).

Patch 3 (this series) adds additional error checking and warning
messages. One of the error checks now makes use of the previously
unused rdb_CylBlocks field, which causes a 'sparse' warning
(cast to restricted __be32).

Annotate all 32 bit fields in affs_hardblocks.h as __be32, as the
on-disk format of RDB and partition blocks is always big endian.

97228ca375 powerpc/ptrace: Expose HASHKEYR register to ptrace 
The HASHKEYR register contains a secret per-process key to enable unique
hashes per process. In general it should not be exposed to userspace
at all and a regular process has no need to know its key.

However, checkpoint restore in userspace (CRIU) functionality requires
that a process be able to set the HASHKEYR of another process, otherwise
existing hashes on the stack would be invalidated by a new random key.

Exposing HASHKEYR in this way also makes it appear in core dumps, which
is a security concern. Multiple threads may share a key, for example
just after a fork() call, where the kernel cannot know if the child is
going to return back along the parent's stack. If such a thread is
coerced into making a core dump, then the HASHKEYR value will be
readable and able to be used against all other threads sharing that key,
effectively undoing any protection offered by hashst/hashchk.

Therefore we expose HASHKEYR to ptrace when CONFIG_CHECKPOINT_RESTORE is
enabled, providing a choice of increased security or migratable ROP
protected processes. This is similar to how ARM exposes its PAC keys.

884ad5c52d powerpc/ptrace: Expose DEXCR and HDEXCR registers to ptrace 
The DEXCR register is of interest when ptracing processes. Currently it
is static, but eventually will be dynamically controllable by a process.
If a process can control its own, then it is useful for it to be
ptrace-able to (e.g., for checkpoint-restore functionality).

It is also relevant to core dumps (the NPHIE aspect in particular),
which use the ptrace mechanism (or is it the other way around?) to
decide what to dump. The HDEXCR is useful here too, as the NPHIE aspect
may be set in the HDEXCR without being set in the DEXCR. Although the
HDEXCR is per-cpu and we don't track it in the task struct (it's useless
in normal operation), it would be difficult to imagine why a hypervisor
would set it to different values within a guest. A hypervisor cannot
safely set NPHIE differently at least, as that would break programs.

Expose a read-only view of the userspace DEXCR and HDEXCR to ptrace.
The HDEXCR is always readonly, and is useful for diagnosing the core
dumps (as the HDEXCR may set NPHIE without the DEXCR setting it).

d297eedf83 drm/amdkfd: bump kfd ioctl minor version for event age availability 
Bump the minor version to declare event age tracking feature is now
available.

In kernel amdgpu driver, kfd_wait_on_events is used to support user
space signal event wait function. For multiple threads waiting on same
event scenery, race condition could occur since some threads after
checking signal condition, before calling kfd_wait_on_events, the
event interrupt could be fired and wake up other thread which are
sleeping on this event. Then those threads could fall into sleep
without waking up again. Adding event age tracking in both kernel and
user mode, will help avoiding this race condition.

508b662b69 Merge branch 'topic/midi20' into for-next 
As the updated MIDI 2.0 spec has been published freshly, this is a
catch up to add the support for new specs, especially UMP v1.1
features, on Linux kernel.

The new UMP v1.1 introduced the concept of Function Blocks (FB), which
is a kind of superset of USB MIDI 2.0 Group Terminal Blocks (GTB).
The patch set adds the support for FB as the primary information
source while keeping the parse of GTB as fallback.  Also UMP v1.1
supports the groupless messages, the protocol switch, static FBs, and
other new fundamental features, and those are supported as well.

01dfa8e969 ALSA: ump: Add info flag bit for static blocks 
UMP v1.1 spec allows to inform whether the function blocks are static
and not dynamically updated.  Add a new flag bit to
snd_ump_endpoint_info to reflect that attribute, too.

The flag is set when a USB MIDI device is still in the old MIDI 2.0
without UMP 1.1 support.  Then the driver falls back to GTBs, and they
are supposed to be static-only.

5437ac9bad ALSA: seq: ump: Handle groupless messages 
The UMP Utility and Stream messages are "groupless", i.e. an incoming
groupless packet should be sent only to the UMP EP port, and the event
with the groupless message is sent to UMP EP as is without the group
translation per port.

Also, the former reserved bit 0 for the client group filter is now
used for groupless events.  When the bit 0 is set, the groupless
events are filtered out and skipped.

Add a few more fields to snd_ump_endpoint_info and snd_ump_block_info
that are added in the new v1.1 spec.  Those are filled by the UMP Stream
messages.

The rawmidi protocol version is bumped to 2.0.4 to indicate those
updates.

Also, update the proc outputs to show the newly introduced fields.

7b26952a91 net: core: add getsockopt SO_PEERPIDFD 
Add SO_PEERPIDFD which allows to get pidfd of peer socket holder pidfd.
This thing is direct analog of SO_PEERCRED which allows to get plain PID.
