999f663186 Including fixes from bpf and wireless. 
Nothing scary here. Feels like the first wave of regressions
 from v6.5 is addressed - one outstanding fix still to come
 in TLS for the sendpage rework.
 
 Current release - regressions:
 
  - udp: fix __ip_append_data()'s handling of MSG_SPLICE_PAGES
 
  - dsa: fix older DSA drivers using phylink
 
 Previous releases - regressions:
 
  - gro: fix misuse of CB in udp socket lookup
 
  - mlx5: unregister devlink params in case interface is down
 
  - Revert "wifi: ath11k: Enable threaded NAPI"
 
 Previous releases - always broken:
 
  - sched: cls_u32: fix match key mis-addressing
 
  - sched: bind logic fixes for cls_fw, cls_u32 and cls_route
 
  - add bound checks to a number of places which hand-parse netlink
 
  - bpf: disable preemption in perf_event_output helpers code
 
  - qed: fix scheduling in a tasklet while getting stats
 
  - avoid using APIs which are not hardirq-safe in couple of drivers,
    when we may be in a hard IRQ (netconsole)
 
  - wifi: cfg80211: fix return value in scan logic, avoid page
    allocator warning
 
  - wifi: mt76: mt7615: do not advertise 5 GHz on first PHY
    of MT7615D (DBDC)
 
 Misc:
 
  - drop handful of inactive maintainers, put some new in place

array must be declared as

	struct nlattr *array[XXX_MAX + 1];

I also changed TCA_FLOWER_KEY_CFM_OPT_MAX and cfm_opt_policy
definitions.

a0ade8404c af_packet: Fix warning of fortified memcpy() in packet_getname(). 
syzkaller found a warning in packet_getname() [0], where we try to
copy 16 bytes to sockaddr_ll.sll_addr[8].

Some devices (ip6gre, vti6, ip6tnl) have 16 bytes address expressed
by struct in6_addr.  Also, Infiniband has 32 bytes as MAX_ADDR_LEN.

The write seems to overflow, but actually not since we use struct
sockaddr_storage defined in __sys_getsockname() and its size is 128
(_K_SS_MAXSIZE) bytes.  Thus, we have sufficient room after sll_addr[]
as __data[].

To avoid the warning, let's add a flex array member union-ed with
sll_addr.

Another option would be to use strncpy() and limit the copied length
to sizeof(sll_addr), but it will return the partial address and break
an application that passes sockaddr_storage to getsockname().

[0]:
memcpy: detected field-spanning write (size 16) of single field "sll->sll_addr" at net/packet/af_packet.c:3604 (size 8)

01f23c5f15 usb: ch9: Replace bmSublinkSpeedAttr 1-element array with flexible array 
Since commit 2d47c6956a ("ubsan: Tighten UBSAN_BOUNDS on GCC"),
UBSAN_BOUNDS no longer pretends 1-element arrays are unbounded. Walking
bmSublinkSpeedAttr will trigger a warning, so make it a proper flexible
array. Add a union to keep the struct size identical for userspace in
case anything was depending on the old size.

False positive warning was:

UBSAN: array-index-out-of-bounds in drivers/usb/host/xhci-hub.c:231:31 index 1 is out of range for type '__le32 [1]'

for this line of code:

	ssp_cap->bmSublinkSpeedAttr[offset++] = cpu_to_le32(attr);

406fb9eb19 firewire updates for 6.5-rc1 
The updates consist of three parts; UAPI update, OHCI driver update, and
 several bug fixes.
 
 Firstly, the 1394 OHCI specification defines method to retrieve hardware
 time stamps for asynchronous communication, which was previously
 unavailable in user space. This change adds new events to the UAPI,
 allowing applications to retrieve the time when asynchronous packet are
 received and sent. The new events are tested in the breeding edge of
 libhinawa and look to work well. The new version of libhinawa will be
 released after current merge window is closed.
 
 * https://git.kernel.org/pub/scm/libs/ieee1394/libhinawa.git/
 
 Secondly, the FireWire stack includes a PCM device driver for 1394 OHCI
 hardware, This change modernizes the driver by managed resource (devres)
 framework.
 
 Lastly, the rest of change is bug fixes for firewire-net and firewire-core.

228a27cf78 vhost: Allow worker switching while work is queueing 
This patch drops the requirement that we can only switch workers if work
has not been queued by using RCU for the vq based queueing paths and a
mutex for the device wide flush.

We can also use this to support SIGKILL properly in the future where we
should exit almost immediately after getting that signal. With this
patch, when get_signal returns true, we can set the vq->worker to NULL
and do a synchronize_rcu to prevent new work from being queued to the
vhost_task that has been killed.

c1ecd8e950 vhost: allow userspace to create workers 
For vhost-scsi with 3 vqs or more and a workload that tries to use
them in parallel like:

fio --filename=/dev/sdb  --direct=1 --rw=randrw --bs=4k \
--ioengine=libaio --iodepth=128  --numjobs=3

the single vhost worker thread will become a bottlneck and we are stuck
at around 500K IOPs no matter how many jobs, virtqueues, and CPUs are
used.

To better utilize virtqueues and available CPUs, this patch allows
userspace to create workers and bind them to vqs. You can have N workers
per dev and also share N workers with M vqs on that dev.

This patch adds the interface related code and the next patch will hook
vhost-scsi into it. The patches do not try to hook net and vsock into
the interface because:

1. multiple workers don't seem to help vsock. The problem is that with
only 2 virtqueues we never fully use the existing worker when doing
bidirectional tests. This seems to match vhost-scsi where we don't see
the worker as a bottleneck until 3 virtqueues are used.

2. net already has a way to use multiple workers.

  - Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
    services that live in the Secure world. pKVM intervenes on FF-A calls
    to guarantee the host doesn't misuse memory donated to the hyp or a
    pKVM guest.
 
  - Support for running the split hypervisor with VHE enabled, known as
    'hVHE' mode. This is extremely useful for testing the split
    hypervisor on VHE-only systems, and paves the way for new use cases
    that depend on having two TTBRs available at EL2.
 
  - Generalized framework for configurable ID registers from userspace.
    KVM/arm64 currently prevents arbitrary CPU feature set configuration
    from userspace, but the intent is to relax this limitation and allow
    userspace to select a feature set consistent with the CPU.
 
  - Enable the use of Branch Target Identification (FEAT_BTI) in the
    hypervisor.
 
  - Use a separate set of pointer authentication keys for the hypervisor
    when running in protected mode, as the host is untrusted at runtime.
 
  - Ensure timer IRQs are consistently released in the init failure
    paths.
 
  - Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
    (FEAT_EVT), as it is a register commonly read from userspace.
 
  - Erratum workaround for the upcoming AmpereOne part, which has broken
    hardware A/D state management.
 
 As a consequence of the hVHE series reworking the arm64 software
 features framework, the for-next/module-alloc branch from the arm64 tree
 comes along for the ride.

Merge tag 'pci-v6.5-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Export pcie_retrain_link() for use outside ASPM

   - Add Data Link Layer Link Active Reporting as another way for
     pcie_retrain_link() to determine the link is up

   - Work around link training failures (especially on the ASMedia
     ASM2824 switch) by training first at 2.5GT/s and then attempting
     higher rates

  Resource management:

   - When we coalesce host bridge windows, remove invalidated resources
     from the resource tree so future allocations work correctly

  Hotplug:

   - Cancel bringup sequence if card is not present, to keep from
     blinking Power Indicator indefinitely

   - Reassign bridge resources if necessary for ACPI hotplug

  Driver binding:

   - Convert platform_device .remove() callbacks to return void instead
     of a mostly useless int

  Power management:

   - Reduce wait time for secondary bus to be ready to speed up resume

   - Avoid putting EloPOS E2/S2/H2 (as well as Elo i2) PCIe Ports in
     D3cold

   - Call _REG when transitioning D-states so AML that uses the PCI
     config space OpRegion works, which fixes some ASMedia GPIO
     controllers after resume

  Virtualization:

   - Delay extra 250ms after FLR of Solidigm P44 Pro NVMe to avoid KVM
     hang when guest is rebooted

   - Add function 1 DMA alias quirk for Marvell 88SE9235

  Error handling:

   - Unexport pci_save_aer_state() since it's only used in drivers/pci/

   - Drop recommendation for drivers to configure AER Capability, since
     the PCI core does this for all devices

  ASPM:

   - Disable ASPM on MFD function removal to avoid use-after-free

   - Tighten up pci_enable_link_state() and pci_disable_link_state()
     interfaces so they don't enable/disable states the driver didn't
     specify

   - Avoid link retraining race that can happen if ASPM sets link
     control parameters while the link is in the midst of training for
     some other reason

  Endpoint framework:

   - Change "PCI Endpoint Virtual NTB driver" Kconfig prompt to be
     different from "PCI Endpoint NTB driver"

   - Automatically create a function specific attributes group for
     endpoint drivers to avoid reference counting issues

   - Fix many EPC test issues

   - Return pci_epf_type_add_cfs() error if EPF has no driver

   - Add kernel-doc for pci_epc_raise_irq() and pci_epc_map_msi_irq()
     MSI vector parameters

   - Pass EPF device ID to driver probe functions

   - Return -EALREADY if EPC has already been started/stopped

   - Add linkdown notifier support and use it in qcom-ep

   - Add Bus Master Enable event support and use it in qcom-ep

   - Add Qualcomm Modem Host Interface (MHI) endpoint driver

   - Add Layerscape PME interrupt handling to manage link-up
     notification

  Cadence PCIe controller driver:

   - Wait for link retrain to complete when working around the J721E
     i2085 erratum with Gen2 mode

  Faraday FTPC100 PCI controller driver:

   - Release clock resources on error paths

  Freescale i.MX6 PCIe controller driver:

   - Save and restore Root Port MSI control to work around hardware defect

  Intel VMD host bridge driver:

   - Reset VMD config register between soft reboots

   - Capture pci_reset_bus() return value instead of printing junk when
     it fails

  Qualcomm PCIe controller driver:

   - Add SDX65 endpoint compatible string to DT binding

   - Disable register write access after init for IP v2.3.3, v2.9.0

   - Use DWC helpers for enabling/disabling writes to DBI registers

   - Hide slot hotplug capability for IP v1.0.0, v1.9.0, v2.1.0, v2.3.2,
     v2.3.3, v2.7.0, v2.9.0

   - Reuse v2.3.2 post-init sequence for v2.4.0

  Renesas R-Car PCIe controller driver:

   - Remove unused static pcie_base and pcie_dev

  Rockchip PCIe controller driver:

   - Remove writes to unused registers

   - Write endpoint Device ID using correct register

   - Assert PCI Configuration Enable bit after probe so endpoint
     responds instead of generating Request Retry Status messages

   - Poll waiting for PHY PLLs to lock

   - Update RK3399 example DT binding to be valid

   - Use RK3399 PCIE_CLIENT_LEGACY_INT_CTRL to generate INTx instead of
     manually generating PCIe message

   - Use multiple windows to avoid address translation conflicts

   - Use u32 (not u16) when accessing 32-bit registers

   - Hide MSI-X Capability, since RK3399 can't generate MSI-X

   - Set endpoint controller required alignment to 256

  Synopsys DesignWare PCIe controller driver:

   - Wait for link to come up only if we've initiated link training

  Miscellaneous:

   - Add pci_clear_master() stub for non-CONFIG_PCI"

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.

9408d8a37e nvme: improved uring polling 
Drivers can poll requests directly, so use that. We just need to ensure
the driver's request was allocated from a polled hctx, so a special
driver flag is added to struct io_uring_cmd.

The allows unshared and multipath namespaces to use the same polling
callback, and multipath is guaranteed to get the same queue as the
command was submitted on. Previously multipath polling might check a
different path and poll the wrong info.

The other bonus is we don't need a bio payload in order to poll,
allowing commands like 'flush' and 'write zeroes' to be submitted on the
same high priority queue as read and write commands.

Finally, using the request based polling skips the unnecessary bio
overhead.

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 df8fc4e934.

  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

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.

8) Use NLA_POLICY_MAX to narrow down maximum attribute value in nf_tables,
   from Florian Westphal.

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

     POSIX"

Marc Kleine-Budde says:

====================
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.

735d86a8aa can: uapi: move CAN_RAW_FILTER_MAX definition to raw.h 
CAN_RAW_FILTER_MAX is only relevant for CAN_RAW sockets and used in
linux/can/raw.c or in userspace applications that include the raw.h
file anyway.

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
