8fa590bf34 ARM64: 
* Enable the per-vcpu dirty-ring tracking mechanism, together with an
   option to keep the good old dirty log around for pages that are
   dirtied by something other than a vcpu.
 
 * Switch to the relaxed parallel fault handling, using RCU to delay
   page table reclaim and giving better performance under load.
 
 * Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping option,
   which multi-process VMMs such as crosvm rely on (see merge commit 382b5b87a9:
   "Fix a number of issues with MTE, such as races on the tags being
   initialised vs the PG_mte_tagged flag as well as the lack of support
   for VM_SHARED when KVM is involved.  Patches from Catalin Marinas and
   Peter Collingbourne").
 
 * Merge the pKVM shadow vcpu state tracking that allows the hypervisor
   to have its own view of a vcpu, keeping that state private.
 
 * Add support for the PMUv3p5 architecture revision, bringing support
   for 64bit counters on systems that support it, and fix the
   no-quite-compliant CHAIN-ed counter support for the machines that
   actually exist out there.
 
 * Fix a handful of minor issues around 52bit VA/PA support (64kB pages
   only) as a prefix of the oncoming support for 4kB and 16kB pages.
 
 * Pick a small set of documentation and spelling fixes, because no
   good merge window would be complete without those.

041fae9c10 f2fs-for-6.2-rc1 
In this round, we've added two features: 1) F2FS_IOC_START_ATOMIC_REPLACE and
 2) per-block age-based extent cache. 1) is a variant of the previous atomic
 write feature which guarantees a per-file atomicity. It would be more efficient
 than AtomicFile implementation in Android framework. 2) implements another type
 of extent cache in memory which keeps the per-block age in a file, so that block
 allocator could split the hot and cold data blocks more accurately.
 
 Enhancement:
  - introduce F2FS_IOC_START_ATOMIC_REPLACE
  - refactor extent_cache to add a new per-block-age-based extent cache support
  - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs
  - add proc entry to show discard_plist info
  - optimize iteration over sparse directories
  - add barrier mount option
 
 Bug fix
  - avoid victim selection from previous victim section
  - fix to enable compress for newly created file if extension matches
  - set zstd compress level correctly
  - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot
  - correct i_size change for atomic writes
  - allow to read node block after shutdown
  - allow to set compression for inlined file
  - fix gc mode when gc_urgent_high_remaining is 1
  - should put a page when checking the summary info
 
 Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and doc.

Merge tag 'pci-v6.2-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Squash portdrv_{core,pci}.c into portdrv.c to ease maintenance and
     make more things static.

   - Make portdrv bind to Switch Ports that have AER. Previously, if
     these Ports lacked MSI/MSI-X, portdrv failed to bind, which meant
     the Ports couldn't be suspended to low-power states. AER on these
     Ports doesn't use interrupts, and the AER driver doesn't need to
     claim them.

   - Assign PCI domain IDs using ida_alloc(), which makes host bridge
     add/remove work better.

  Resource management:

   - To work better with recent BIOSes that use EfiMemoryMappedIO for
     PCI host bridge apertures, remove those regions from the E820 map
     (E820 entries normally prevent us from allocating BARs). In v5.19,
     we added some quirks to disable E820 checking, but that's not very
     maintainable. EfiMemoryMappedIO means the OS needs to map the
     region for use by EFI runtime services; it shouldn't prevent OS
     from using it.

  PCIe native device hotplug:

   - Build pciehp by default if USB4 is enabled, since Thunderbolt/USB4
     PCIe tunneling depends on native PCIe hotplug.

   - Enable Command Completed Interrupt only if supported to avoid user
     confusion from lspci output that says this is enabled but not
     supported.

   - Prevent pciehp from binding to Switch Upstream Ports; this happened
     because of interaction with acpiphp and caused devices below the
     Upstream Port to disappear.

  Power management:

   - Convert AGP drivers to generic power management. We hope to remove
     legacy power management from the PCI core eventually.

  Virtualization:

   - Fix pci_device_is_present(), which previously always returned
     "false" for VFs, causing virtio hangs when unbinding the driver.

  Miscellaneous:

   - Convert drivers to gpiod API to prepare for dropping some legacy
     code.

   - Fix DOE fencepost error for the maximum data object length.

  Baikal-T1 PCIe controller driver:

   - Add driver and DT bindings.

  Broadcom STB PCIe controller driver:

   - Enable Multi-MSI.

   - Delay 100ms after PERST# deassert to allow power and clocks to
     stabilize.

   - Configure Read Completion Boundary to 64 bytes.

  Freescale i.MX6 PCIe controller driver:

   - Initialize PHY before deasserting core reset to fix a regression in
     v6.0 on boards where the PHY provides the reference.

   - Fix imx6sx and imx8mq clock names in DT schema.

  Intel VMD host bridge driver:

   - Fix Secondary Bus Reset on VMD bridges, which allows reset of NVMe
     SSDs in VT-d pass-through scenarios.

   - Disable MSI remapping, which gets re-enabled by firmware during
     suspend/resume.

  MediaTek PCIe Gen3 controller driver:

   - Add MT7986 and MT8195 support.

  Qualcomm PCIe controller driver:

   - Add SC8280XP/SA8540P basic interconnect support.

  Rockchip DesignWare PCIe controller driver:

   - Base DT schema on common Synopsys schema.

  Synopsys DesignWare PCIe core:

   - Collect DT items shared between Root Port and Endpoint (PERST GPIO,
     PHY info, clocks, resets, link speed, number of lanes, number of
     iATU windows, interrupt info, etc) to snps,dw-pcie-common.yaml.

   - Add dma-ranges support for Root Ports and Endpoints.

   - Consolidate DT resource retrieval for "dbi", "dbi2", "atu", etc. to
     reduce code duplication.

   - Add generic names for clocks and resets to encourage more
     consistent naming across drivers using DesignWare IP.

   - Stop advertising PTM Responder role for Endpoints, which aren't
     allowed to be responders.

  TI J721E PCIe driver:

   - Add j721s2 host mode ID to DT schema.

   - Add interrupt properties to DT schema.

  Toshiba Visconti PCIe controller driver:

   - Fix interrupts array max constraints in DT schema"

08cdc21579 iommufd for 6.2 
iommufd is the user API to control the IOMMU subsystem as it relates to
 managing IO page tables that point at user space memory.
 
 It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO
 container) which is the VFIO specific interface for a similar idea.
 
 We see a broad need for extended features, some being highly IOMMU device
 specific:
  - Binding iommu_domain's to PASID/SSID
  - Userspace IO page tables, for ARM, x86 and S390
  - Kernel bypassed invalidation of user page tables
  - Re-use of the KVM page table in the IOMMU
  - Dirty page tracking in the IOMMU
  - Runtime Increase/Decrease of IOPTE size
  - PRI support with faults resolved in userspace
 
 Many of these HW features exist to support VM use cases - for instance the
 combination of PASID, PRI and Userspace IO Page Tables allows an
 implementation of DMA Shared Virtual Addressing (vSVA) within a
 guest. Dirty tracking enables VM live migration with SRIOV devices and
 PASID support allow creating "scalable IOV" devices, among other things.
 
 As these features are fundamental to a VM platform they need to be
 uniformly exposed to all the driver families that do DMA into VMs, which
 is currently VFIO and VDPA.

Pull drm updates from Dave Airlie:
 "The biggest highlight is that the accel subsystem framework is merged.
  Hopefully for 6.3 we will be able to line up a driver to use it.

  In drivers land, i915 enables DG2 support by default now, and nouveau
  has a big stability refactoring and initial ampere support, AMD
  includes new hw IP support and should build on ARM again. There is
  also an ofdrm driver to take over offb on platforms it's used.

  Stuff outside my tree, the dma-buf patches hit a few places, the vc4
  firmware changes also do, and i915 has some interactions with MEI for
  discrete GPUs. I think all of those should have been acked/reviewed by

102f9d3d45 sound updates for 6.2-rc1 
This looks like a relatively calm development cycle; there have been
 only few changes in ALSA and ASoC core sides while we get lots of
 device-specific fixes and updates as usual.  Most of commits are about
 ASoC, including Intel SOF/AVS and many device tree updates.
 
 Below are some highlights:
 
 Core:
 - Improvement in memalloc helper for fallback allocations
 - More cleanups of ASoC DAPM code
 
 ASoC:
 - Factoring out of mapping hw_params onto SoundWire configuration
 - The ever ongoing overhauls of the Intel DSP code continue, including
   support for loading libraries and probes with IPC4 on SOF.
 - Support for more sample formats on JZ4740
 - Lots of device tree conversions and fixups
 - Support for Allwinner D1, a range of AMD and Intel systems, Mediatek
   systems with multiple DMICs, Nuvoton NAU8318, NXP fsl_rpmsg and
   i.MX93, Qualcomm AudioReach Enable, MFC and SAL, RealTek RT1318 and
   Rockchip RK3588
 
 ALSA:
 - Addition of PCM kselftest; still minimalistic but can be extended
   in future
 - Fixes for corner-case XRUNs with USB-audio implicit feedback mode
 - Usual device-specific quirk updates for USB- and HD-audio
 - FireWire DICE updates
 
 Also, this PR also contains a few cross-tree updates:
 - Some OMAP board file updates for removal of relevant OMAP platforms
 - A new I2C API update for I2C probe API adaption
 - A DRM update for the further hdmi-codec updates

Merge tag 'for-6.2/io_uring-2022-12-08' of git://git.kernel.dk/linux

Pull io_uring updates from Jens Axboe:

 - Always ensure proper ordering in case of CQ ring overflow, which then
   means we can remove some work-arounds for that (Dylan)

 - Support completion batching for multishot, greatly increasing the
   efficiency for those (Dylan)

 - Flag epoll/eventfd wakeups done from io_uring, so that we can easily
   tell if we're recursing into io_uring again.

   Previously, this would have resulted in repeated multishot
   notifications if we had a dependency there. That could happen if an
   eventfd was registered as the ring eventfd, and we multishot polled
   for events on it. Or if an io_uring fd was added to epoll, and
   io_uring had a multishot request for the epoll fd.

   Test cases here:
	https://git.kernel.dk/cgit/liburing/commit/?id=919755a7d0096fda08fb6d65ac54ad8d0fe027cd

   Previously these got terminated when the CQ ring eventually
   overflowed, now it's handled gracefully (me).

 - Tightening of the IOPOLL based completions (Pavel)

 - Optimizations of the networking zero-copy paths (Pavel)

 - Various tweaks and fixes (Dylan, Pavel)

  Landlock is described at [2]. Out of the operations listed there,
  truncate is the only one that modifies file contents, so these patches
  should make it possible to prevent the direct modification of file
  contents with Landlock.

  The new LANDLOCK_ACCESS_FS_TRUNCATE access right covers both the
  truncate(2) and ftruncate(2) families of syscalls, as well as open(2)
  with the O_TRUNC flag. This includes usages of creat() in the case
  where existing regular files are overwritten.

  Additionally, this introduces a new Landlock security blob associated
  with opened files, to track the available Landlock access rights at
  the time of opening the file. This is in line with Unix's general
  approach of checking the read and write permissions during open(), and
  associating this previously checked authorization with the opened
  file. An ongoing patch documents this use case [3].

  In order to treat truncate(2) and ftruncate(2) calls differently in an
  LSM hook, we split apart the existing security_path_truncate hook into
  security_path_truncate (for truncation by path) and
  security_file_truncate (for truncation of previously opened files)"

Pull btrfs updates from David Sterba:
 "This round there are a lot of cleanups and moved code so the diffstat
  looks huge, otherwise there are some nice performance improvements and
  an update to raid56 reliability.

  User visible features:

   - raid56 reliability vs performance trade off:
      - fix destructive RMW for raid5 data (raid6 still needs work): do
        full checksum verification for all data during RMW cycle, this
        should prevent rewriting potentially corrupted data without
        notice
      - stripes are cached in memory which should reduce the performance
        impact but still can hurt some workloads
      - checksums are verified after repair again
      - this is the last option without introducing additional features
        (write intent bitmap, journal, another tree), the extra checksum
        read/verification was supposed to be avoided by the original
        implementation exactly for performance reasons but that caused
        all the reliability problems

   - discard=async by default for devices that support it

   - implement emergency flush reserve to avoid almost all unnecessary
     transaction aborts due to ENOSPC in cases where there are too many
     delayed refs or delayed allocation

   - skip block group synchronization if there's no change in used
     bytes, can reduce transaction commit count for some workloads

  Performance improvements:

   - fiemap and lseek:
      - overall speedup due to skipping unnecessary or duplicate
        searches (-40% run time)
      - cache some data structures and sharedness of extents (-30% run
        time)

   - send:
      - faster backref resolution when finding clones
      - cached leaf to root mapping for faster backref walking
      - improved clone/sharing detection
      - overall run time improvements (-70%)

  Core:

   - module initialization converted to a table of function pointers run
     in a sequence

   - preparation for fscrypt, extend passing file names across calls,
     dir item can store encryption status

   - raid56 updates:
      - more accurate error tracking of sectors within stripe
      - simplify recovery path and remove dedicated endio worker kthread
      - simplify scrub call paths
      - refactoring to support the extra data checksum verification
        during RMW cycle

   - tree block parentness checks consolidated and done at metadata read
     time

   - improved error handling

   - cleanups:
      - move a lot of code for better synchronization between kernel and
        user space sources, split big files
      - enum cleanups
      - GFP flag cleanups
      - header file cleanups, prototypes, dependencies
      - redundant parameter cleanups
      - inline extent handling simplifications
      - inode parameter conversion

1d7b66a7d9 bridge: mcast: Allow user space to specify MDB entry routing protocol 
Add the 'MDBE_ATTR_RTPORT' attribute to allow user space to specify the
routing protocol of the MDB port group entry. Enforce a minimum value of
'RTPROT_STATIC' to prevent user space from using protocol values that
should only be set by the kernel (e.g., 'RTPROT_KERNEL'). Maintain
backward compatibility by defaulting to 'RTPROT_STATIC'.

The protocol is already visible to user space in RTM_NEWMDB responses
and notifications via the 'MDBA_MDB_EATTR_RTPROT' attribute.

The routing protocol allows a routing daemon to distinguish between
entries configured by it and those configured by the administrator. Once
MDB flush is supported, the protocol can be used as a criterion
according to which the flush is performed.

Examples:

 # bridge mdb add dev br0 port dummy10 grp 239.1.1.1 permanent proto kernel
 Error: integer out of range.

 # bridge mdb add dev br0 port dummy10 grp 239.1.1.1 permanent proto static

 # bridge mdb add dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.1 permanent proto zebra

 # bridge mdb add dev br0 port dummy10 grp 239.1.1.2 permanent source_list 198.51.100.1,198.51.100.2 filter_mode include proto 250

Add new netlink attributes to the RTM_NEWMDB request that allow user
space to add (*, G) with a source list and filter mode.

The RTM_NEWMDB message can already dump such entries (created by the
kernel) so there is no need to add dump support. However, the message
contains a different set of attributes depending if it is a request or a
response. The naming and structure of the new attributes try to follow
the existing ones used in the response.

Netfilter/IPVS updates for net-next

1) Incorrect error check in nft_expr_inner_parse(), from Dan Carpenter.

2) Add DATA_SENT state to SCTP connection tracking helper, from
   Sriram Yagnaraman.

3) Consolidate nf_confirm for ipv4 and ipv6, from Florian Westphal.

4) Add bitmask support for ipset, from Vishwanath Pai.

5) Handle icmpv6 redirects as RELATED, from Florian Westphal.

6) Add WARN_ON_ONCE() to impossible case in flowtable datapath,
   from Li Qiong.

7) A large batch of IPVS updates to replace timer-based estimators by
   kthreads to scale up wrt. CPUs and workload (millions of estimators).

Julian Anastasov says:

	This patchset implements stats estimation in kthread context.
It replaces the code that runs on single CPU in timer context every 2
seconds and causing latency splats as shown in reports [1], [2], [3].
The solution targets setups with thousands of IPVS services,
destinations and multi-CPU boxes.

	Spread the estimation on multiple (configured) CPUs and multiple
time slots (timer ticks) by using multiple chains organized under RCU
rules.  When stats are not needed, it is recommended to use
run_estimation=0 as already implemented before this change.

RCU Locking:

- As stats are now RCU-locked, tot_stats, svc and dest which
hold estimator structures are now always freed from RCU
callback. This ensures RCU grace period after the
ip_vs_stop_estimator() call.

Kthread data:

- every kthread works over its own data structure and all
such structures are attached to array. For now we limit
kthreads depending on the number of CPUs.

- even while there can be a kthread structure, its task
may not be running, eg. before first service is added or
while the sysctl var is set to an empty cpulist or
when run_estimation is set to 0 to disable the estimation.

- the allocated kthread context may grow from 1 to 50
allocated structures for timer ticks which saves memory for
setups with small number of estimators

- a task and its structure may be released if all
estimators are unlinked from its chains, leaving the
slot in the array empty

- every kthread data structure allows limited number
of estimators. Kthread 0 is also used to initially
calculate the max number of estimators to allow in every
chain considering a sub-100 microsecond cond_resched
rate. This number can be from 1 to hundreds.

- kthread 0 has an additional job of optimizing the
adding of estimators: they are first added in
temp list (est_temp_list) and later kthread 0
distributes them to other kthreads. The optimization
is based on the fact that newly added estimator
should be estimated after 2 seconds, so we have the
time to offload the adding to chain from controlling
process to kthread 0.

- to add new estimators we use the last added kthread
context (est_add_ktid). The new estimators are linked to
the chains just before the estimated one, based on add_row.
This ensures their estimation will start after 2 seconds.
If estimators are added in bursts, common case if all
services and dests are initially configured, we may
spread the estimators to more chains and as result,
reducing the initial delay below 2 seconds.

Many thanks to Jiri Wiesner for his valuable comments
and for spending a lot of time reviewing and testing
the changes on different platforms with 48-256 CPUs and
1-8 NUMA nodes under different cpufreq governors.

The new IPVS estimators do not use workqueue infrastructure
because:

- The estimation can take long time when using multiple IPVS rules (eg.
  millions estimator structures) and especially when box has multiple
  CPUs due to the for_each_possible_cpu usage that expects packets from
  any CPU. With est_nice sysctl we have more control how to prioritize the
  estimation kthreads compared to other processes/kthreads that have
  latency requirements (such as servers). As a benefit, we can see these
  kthreads in top and decide if we will need some further control to limit
  their CPU usage (max number of structure to estimate per kthread).

- with kthreads we run code that is read-mostly, no write/lock
  operations to process the estimators in 2-second intervals.

- work items are one-shot: as estimators are processed every
  2 seconds, they need to be re-added every time. This again
  loads the timers (add_timer) if we use delayed works, as there are
  no kthreads to do the timings.

Merge tag 'cxl-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull cxl updates from Dan Williams:
 "Compute Express Link (CXL) updates for 6.2.

  While it may seem backwards, the CXL update this time around includes
  some focus on CXL 1.x enabling where the work to date had been with
  CXL 2.0 (VH topologies) in mind.

  First generation CXL can mostly be supported via BIOS, similar to DDR,
  however it became clear there are use cases for OS native CXL error
  handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
  hosts (Restricted CXL Host (RCH) topologies). So, this update brings
  RCH topologies into the Linux CXL device model.

  In support of the ongoing CXL 2.0+ enabling two new core kernel
  facilities are added.

  One is the ability for the kernel to flag collisions between userspace
  access to PCI configuration registers and kernel accesses. This is
  brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
  mailbox over config-cycles.

  The other is a cpu_cache_invalidate_memregion() API that maps to
  wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
  VMs and architectures that do not support it yet. The CXL paths that
  need it, dynamic memory region creation and security commands (erase /
  unlock), are disabled when it is not present.

  As for the CXL 2.0+ this cycle the subsystem gains support Persistent
  Memory Security commands, error handling in response to PCIe AER
  notifications, and support for the "XOR" host bridge interleave
  algorithm.

  Summary:

   - Add the cpu_cache_invalidate_memregion() API for cache flushing in
     response to physical memory reconfiguration, or memory-side data
     invalidation from operations like secure erase or memory-device
     unlock.

   - Add a facility for the kernel to warn about collisions between
     kernel and userspace access to PCI configuration registers

   - Add support for Restricted CXL Host (RCH) topologies (formerly CXL
     1.1)

   - Add handling and reporting of CXL errors reported via the PCIe AER
     mechanism

   - Add support for CXL Persistent Memory Security commands

   - Add support for the "XOR" algorithm for CXL host bridge interleave

   - Rework / simplify CXL to NVDIMM interactions

   - Miscellaneous cleanups and fixes"

9352e7470a Merge remote-tracking branch 'kvm/queue' into HEAD 
x86 Xen-for-KVM:

* Allow the Xen runstate information to cross a page boundary

* Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured

* add support for 32-bit guests in SCHEDOP_poll

x86 fixes:

* One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).

* Reinstate IBPB on emulated VM-Exit that was incorrectly dropped a few
   years back when eliminating unnecessary barriers when switching between
   vmcs01 and vmcs02.

* Clean up the MSR filter docs.

* Clean up vmread_error_trampoline() to make it more obvious that params
  must be passed on the stack, even for x86-64.

* Let userspace set all supported bits in MSR_IA32_FEAT_CTL irrespective
  of the current guest CPUID.

* Fudge around a race with TSC refinement that results in KVM incorrectly
  thinking a guest needs TSC scaling when running on a CPU with a
  constant TSC, but no hardware-enumerated TSC frequency.

* Advertise (on AMD) that the SMM_CTL MSR is not supported

* Remove unnecessary exports

Selftests:

* Fix an inverted check in the access tracking perf test, and restore
  support for asserting that there aren't too many idle pages when
  running on bare metal.

* Fix an ordering issue in the AMX test introduced by recent conversions
  to use kvm_cpu_has(), and harden the code to guard against similar bugs
  in the future.  Anything that tiggers caching of KVM's supported CPUID,
  kvm_cpu_has() in this case, effectively hides opt-in XSAVE features if
  the caching occurs before the test opts in via prctl().

* Fix build errors that occur in certain setups (unsure exactly what is
  unique about the problematic setup) due to glibc overriding
  static_assert() to a variant that requires a custom message.

* Introduce actual atomics for clear/set_bit() in selftests

Documentation:

* Remove deleted ioctls from documentation

* Various fixes

b534dc46c8 net_tstamp: add SOF_TIMESTAMPING_OPT_ID_TCP 
Add an option to initialize SOF_TIMESTAMPING_OPT_ID for TCP from
write_seq sockets instead of snd_una.

This should have been the behavior from the start. Because processes
may now exist that rely on the established behavior, do not change
behavior of the existing option, but add the right behavior with a new
flag. It is encouraged to always set SOF_TIMESTAMPING_OPT_ID_TCP on
stream sockets along with the existing SOF_TIMESTAMPING_OPT_ID.

Intuitively the contract is that the counter is zero after the
setsockopt, so that the next write N results in a notification for
the last byte N - 1.

On idle sockets snd_una == write_seq and this holds for both. But on
sockets with data in transmission, snd_una records the unacked offset
in the stream. This depends on the ACK response from the peer. A
process cannot learn this in a race free manner (ioctl SIOCOUTQ is one
racy approach).

write_seq records the offset at the last byte written by the process.
This is a better starting point. It matches the intuitive contract in
all circumstances, unaffected by external behavior.

The new timestamp flag necessitates increasing sk_tsflags to 32 bits.
Move the field in struct sock to avoid growing the socket (for some
common CONFIG variants). The UAPI interface so_timestamping.flags is
already int, so 32 bits wide.

2706053173 bpf: Rework process_dynptr_func 
Recently, user ringbuf support introduced a PTR_TO_DYNPTR register type
for use in callback state, because in case of user ringbuf helpers,
there is no dynptr on the stack that is passed into the callback. To
reflect such a state, a special register type was created.

However, some checks have been bypassed incorrectly during the addition
of this feature. First, for arg_type with MEM_UNINIT flag which
initialize a dynptr, they must be rejected for such register type.
Secondly, in the future, there are plans to add dynptr helpers that
operate on the dynptr itself and may change its offset and other
properties.

In all of these cases, PTR_TO_DYNPTR shouldn't be allowed to be passed
to such helpers, however the current code simply returns 0.

The rejection for helpers that release the dynptr is already handled.

For fixing this, we take a step back and rework existing code in a way
that will allow fitting in all classes of helpers and have a coherent
model for dealing with the variety of use cases in which dynptr is used.

First, for ARG_PTR_TO_DYNPTR, it can either be set alone or together
with a DYNPTR_TYPE_* constant that denotes the only type it accepts.

Next, helpers which initialize a dynptr use MEM_UNINIT to indicate this
fact. To make the distinction clear, use MEM_RDONLY flag to indicate
that the helper only operates on the memory pointed to by the dynptr,
not the dynptr itself. In C parlance, it would be equivalent to taking
the dynptr as a point to const argument.

When either of these flags are not present, the helper is allowed to
mutate both the dynptr itself and also the memory it points to.
Currently, the read only status of the memory is not tracked in the
dynptr, but it would be trivial to add this support inside dynptr state
of the register.

With these changes and renaming PTR_TO_DYNPTR to CONST_PTR_TO_DYNPTR to
better reflect its usage, it can no longer be passed to helpers that
initialize a dynptr, i.e. bpf_dynptr_from_mem, bpf_ringbuf_reserve_dynptr.

A note to reviewers is that in code that does mark_stack_slots_dynptr,
and unmark_stack_slots_dynptr, we implicitly rely on the fact that
PTR_TO_STACK reg is the only case that can reach that code path, as one
cannot pass CONST_PTR_TO_DYNPTR to helpers that don't set MEM_RDONLY. In
both cases such helpers won't be setting that flag.

The next patch will add a couple of selftest cases to make sure this
doesn't break.

c1f480b2d0 sed-opal: allow using IOC_OPAL_SAVE for locking too 
Usually when closing a crypto device (eg: dm-crypt with LUKS) the
volume key is not required, as it requires root privileges anyway, and
root can deny access to a disk in many ways regardless. Requiring the
volume key to lock the device is a peculiarity of the OPAL
specification.

Given we might already have saved the key if the user requested it via
the 'IOC_OPAL_SAVE' ioctl, we can use that key to lock the device if no
key was provided here and the locking range matches, and the user sets
the appropriate flag with 'IOC_OPAL_SAVE'. This allows integrating OPAL
with tools and libraries that are used to the common behaviour and do
not ask for the volume key when closing a device.

Callers can always pass a non-zero key and it will be used regardless,
as before.

In the specification documents for the Uncompressed and MJPEG USB
Video Payloads, the field name is bmInterlaceFlags - it has been
misnamed within the kernel.

Although renaming the field does break the kernel's interface to
userspace it should be low-risk in this instance. The field is read
only and hardcoded to 0, so there was never any value in anyone
reading it. A search of the uvc-gadget application and all the
forks that I could find for it did not reveal any users either.

a8ce7b26a5 devlink: Expose port function commands to control migratable 
Expose port function commands to enable / disable migratable
capability, this is used to set the port function as migratable.

Live migration is the process of transferring a live virtual machine
from one physical host to another without disrupting its normal
operation.

In order for a VM to be able to perform LM, all the VM components must
be able to perform migration. e.g.: to be migratable.
In order for VF to be migratable, VF must be bound to VFIO driver with
migration support.

When migratable capability is enabled for a function of the port, the
device is making the necessary preparations for the function to be
migratable, which might include disabling features which cannot be
migrated.

Example of LM with migratable function configuration:
Set migratable of the VF's port function.

$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0
vfnum 1
    function:
        hw_addr 00:00:00:00:00:00 migratable disable

$ devlink port function set pci/0000:06:00.0/2 migratable enable

$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0
vfnum 1
    function:
        hw_addr 00:00:00:00:00:00 migratable enable

Bind VF to VFIO driver with migration support:
$ echo <pci_id> > /sys/bus/pci/devices/0000:08:00.0/driver/unbind
$ echo mlx5_vfio_pci > /sys/bus/pci/devices/0000:08:00.0/driver_override
$ echo <pci_id> > /sys/bus/pci/devices/0000:08:00.0/driver/bind

Attach VF to the VM.
Start the VM.
Perform LM.

Expose port function commands to enable / disable RoCE, this is used to

7fe898041f cxl/security: Drop security command ioctl uapi 
CXL PMEM security operations are routed through the NVDIMM sysfs
interface. For this reason the corresponding commands are marked
"exclusive" to preclude collisions between the ioctl ABI and the sysfs
ABI. However, a better way to preclude that collision is to simply
remove the ioctl ABI (command-id definitions) for those operations.

Now that cxl_internal_send_cmd() (formerly cxl_mbox_send_cmd()) no
longer needs to talk the cxl_mem_commands array, all of the uapi
definitions for the security commands can be dropped.

These never appeared in a released kernel, so no regression risk.

4db52602a6 vfio: Extend the device migration protocol with PRE_COPY 
The optional PRE_COPY states open the saving data transfer FD before
reaching STOP_COPY and allows the device to dirty track internal state
changes with the general idea to reduce the volume of data transferred
in the STOP_COPY stage.

While in PRE_COPY the device remains RUNNING, but the saving FD is open.

Only if the device also supports RUNNING_P2P can it support PRE_COPY_P2P,
which halts P2P transfers while continuing the saving FD.

PRE_COPY, with P2P support, requires the driver to implement 7 new arcs
and exists as an optional FSM branch between RUNNING and STOP_COPY:
    RUNNING -> PRE_COPY -> PRE_COPY_P2P -> STOP_COPY

A new ioctl VFIO_MIG_GET_PRECOPY_INFO is provided to allow userspace to
query the progress of the precopy operation in the driver with the idea it
will judge to move to STOP_COPY at least once the initial data set is
transferred, and possibly after the dirty size has shrunk appropriately.

This ioctl is valid only in PRE_COPY states and kernel driver should
return -EINVAL from any other migration state.

Compared to the v1 clarification, STOP_COPY -> PRE_COPY is blocked
and to be defined in future.
We also split the pending_bytes report into the initial and sustaining
values, e.g.: initial_bytes and dirty_bytes.
initial_bytes: Amount of initial precopy data.
dirty_bytes: Device state changes relative to data previously retrieved.
These fields are not required to have any bearing to STOP_COPY phase.

It is recommended to leave PRE_COPY for STOP_COPY only after the
initial_bytes field reaches zero. Leaving PRE_COPY earlier might make
things slower.

8ec2d95f50 ASoC: Updates for v6.2 
This is a fairly sedate release for the core code, but there's been a
 lot of driver work especially around the x86 platforms and device tree
 updates:
 
  - More cleanups of the DAPM code from Morimoto-san.
  - Factoring out of mapping hw_params onto SoundWire configuration by
    Charles Keepax.
  - The ever ongoing overhauls of the Intel DSP code continue, including
    support for loading libraries and probes with IPC4 on SOF.
  - Support for more sample formats on JZ4740.
  - Lots of device tree conversions and fixups.
  - Support for Allwinner D1, a range of AMD and Intel systems, Mediatek
    systems with multiple DMICs, Nuvoton NAU8318, NXP fsl_rpmsg and
    i.MX93, Qualcomm AudioReach Enable, MFC and SAL, RealTek RT1318 and
    Rockchip RK3588
 
 There's more cross tree updates than usual, though all fairly minor:
 
  - Some OMAP board file updates that were depedencies for removing their
    providers in ASoC, as part of a wider effort removing the support for
    the relevant OMAP platforms.
  - A new I2C API required for updates to the new I2C probe API.
  - A DRM update making use of a new API for fixing the capabilities
    advertised via hdmi-codec.
 
 Since this is being sent early I might send some more stuff if you've
 not yet sent your pull request and there's more come in.

Merge tag 'asoc-v6.2' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

ASoC: Updates for v6.2

This is a fairly sedate release for the core code, but there's been a
lot of driver work especially around the x86 platforms and device tree
updates:

 - More cleanups of the DAPM code from Morimoto-san.
 - Factoring out of mapping hw_params onto SoundWire configuration by
   Charles Keepax.
 - The ever ongoing overhauls of the Intel DSP code continue, including
   support for loading libraries and probes with IPC4 on SOF.
 - Support for more sample formats on JZ4740.
 - Lots of device tree conversions and fixups.
 - Support for Allwinner D1, a range of AMD and Intel systems, Mediatek
   systems with multiple DMICs, Nuvoton NAU8318, NXP fsl_rpmsg and
   i.MX93, Qualcomm AudioReach Enable, MFC and SAL, RealTek RT1318 and
   Rockchip RK3588

There's more cross tree updates than usual, though all fairly minor:

 - Some OMAP board file updates that were depedencies for removing their
   providers in ASoC, as part of a wider effort removing the support for
   the relevant OMAP platforms.
 - A new I2C API required for updates to the new I2C probe API.
 - A DRM update making use of a new API for fixing the capabilities
   advertised via hdmi-codec.

Since this is being sent early I might send some more stuff if you've
not yet sent your pull request and there's more come in.

94a48aef49 btrfs: extend btrfs_dir_item type to store encryption status 
For directories with encrypted files/filenames, we need to store a flag
indicating this fact. There's no room in other fields, so we'll need to
borrow a bit from dir_type. Since it's now a combination of type and
flags, we rename it to dir_flags to reflect its new usage.

The new flag, FT_ENCRYPTED, indicates a directory containing encrypted
data, which is orthogonal to file type; therefore, add the new
flag, and make conversion from directory type to file type strip the
flag.

As the file types almost never change we can afford to use the bits.
Actual usage will be guarded behind an incompat bit, this patch only
adds the support for later use by fscrypt.

ASoC/tda998x: Fix reporting of nonexistent capture streams 
Merge series from Mark Brown <broonie@kernel.org>:

The recently added pcm-test selftest has pointed out that systems with
the tda998x driver end up advertising that they support capture when in
reality as far as I can see the tda998x devices are transmit only.  The
DAIs registered through hdmi-codec are bidirectional, meaning that for
I2S systems when combined with a typical bidrectional CPU DAI the
overall capability of the PCM is bidirectional.  In most cases the I2S
links will clock OK but no useful audio will be returned which isn't so
bad but we should still not advertise the useless capability, and some
systems may notice problems for example due to pinmux management.

This is happening due to the hdmi-codec helpers not providing any
mechanism for indicating unidirectional audio so add one and use it in
the tda998x driver.  It is likely other hdmi-codec users are also
affected but I don't have those systems to hand.

af6397c9ee devlink: support directly reading from region memory 
To read from a region, user space must currently request a new snapshot of
the region and then read from that snapshot. This can sometimes be overkill
if user space only reads a tiny portion. They first create the snapshot,
then request a read, then destroy the snapshot.

For regions which have a single underlying "contents", it makes sense to
allow supporting direct reading of the region data.

Extend the DEVLINK_CMD_REGION_READ to allow direct reading from a region if
requested via the new DEVLINK_ATTR_REGION_DIRECT. If this attribute is set,
then perform a direct read instead of using a snapshot. Direct read is
mutually exclusive with DEVLINK_ATTR_REGION_SNAPSHOT_ID, and care is taken
to ensure that we reject commands which provide incorrect attributes.

Regions must enable support for direct read by implementing the .read()
callback function. If a region does not support such direct reads, a
suitable extended error message is reported.

d624d6652a iommufd: vfio container FD ioctl compatibility 
iommufd can directly implement the /dev/vfio/vfio container IOCTLs by
mapping them into io_pagetable operations.

A userspace application can test against iommufd and confirm compatibility
then simply make a small change to open /dev/iommu instead of
/dev/vfio/vfio.

For testing purposes /dev/vfio/vfio can be symlinked to /dev/iommu and
then all applications will use the compatibility path with no code
changes. A later series allows /dev/vfio/vfio to be directly provided by
iommufd, which allows the rlimit mode to work the same as well.

This series just provides the iommufd side of compatibility. Actually
linking this to VFIO_SET_CONTAINER is a followup series, with a link in
the cover letter.

Internally the compatibility API uses a normal IOAS object that, like
vfio, is automatically allocated when the first device is
attached.

Userspace can also query or set this IOAS object directly using the
IOMMU_VFIO_IOAS ioctl. This allows mixing and matching new iommufd only
features while still using the VFIO style map/unmap ioctls.

While this is enough to operate qemu, it has a few differences:

 - Resource limits rely on memory cgroups to bound what userspace can do
   instead of the module parameter dma_entry_limit.

 - VFIO P2P is not implemented. The DMABUF patches for vfio are a start at
   a solution where iommufd would import a special DMABUF. This is to avoid
   further propogating the follow_pfn() security problem.

 - A full audit for pedantic compatibility details (eg errnos, etc) has
   not yet been done

 - powerpc SPAPR is left out, as it is not connected to the iommu_domain
   framework. It seems interest in SPAPR is minimal as it is currently
   non-working in v6.1-rc1. They will have to convert to the iommu
   subsystem framework to enjoy iommfd.

The following are not going to be implemented and we expect to remove them
from VFIO type1:

 - SW access 'dirty tracking'. As discussed in the cover letter this will
   be done in VFIO.

aad37e71d5 iommufd: IOCTLs for the io_pagetable 
Connect the IOAS to its IOCTL interface. This exposes most of the
functionality in the io_pagetable to userspace.

This is intended to be the core of the generic interface that IOMMUFD will
provide. Every IOMMU driver should be able to implement an iommu_domain
that is compatible with this generic mechanism.

It is also designed to be easy to use for simple non virtual machine
monitor users, like DPDK:
 - Universal simple support for all IOMMUs (no PPC special path)
 - An IOVA allocator that considers the aperture and the allowed/reserved
   ranges
 - io_pagetable allows any number of iommu_domains to be connected to the
   IOAS
 - Automatic allocation and re-use of iommu_domains

Along with room in the design to add non-generic features to cater to
specific HW functionality.

2ff4bed7fe iommufd: File descriptor, context, kconfig and makefiles 
This is the basic infrastructure of a new miscdevice to hold the iommufd
IOCTL API.

It provides:
 - A miscdevice to create file descriptors to run the IOCTL interface over

 - A table based ioctl dispatch and centralized extendable pre-validation
   step

 - An xarray mapping userspace ID's to kernel objects. The design has
   multiple inter-related objects held within in a single IOMMUFD fd

 - A simple usage count to build a graph of object relations and protect
   against hostile userspace racing ioctls

The only IOCTL provided in this patch is the generic 'destroy any object
by handle' operation.

e937452495 netfilter: ipset: Add support for new bitmask parameter 
Add a new parameter to complement the existing 'netmask' option. The
main difference between netmask and bitmask is that bitmask takes any
arbitrary ip address as input, it does not have to be a valid netmask.

The name of the new parameter is 'bitmask'. This lets us mask out
arbitrary bits in the ip address, for example:
ipset create set1 hash:ip bitmask 255.128.255.0
ipset create set2 hash:ip,port family inet6 bitmask ffff::ff80

bff3d05348 netfilter: conntrack: add sctp DATA_SENT state 
SCTP conntrack currently assumes that the SCTP endpoints will
probe secondary paths using HEARTBEAT before sending traffic.

But, according to RFC 9260, SCTP endpoints can send any traffic
on any of the confirmed paths after SCTP association is up.
SCTP endpoints that sends INIT will confirm all peer addresses
that upper layer configures, and the SCTP endpoint that receives
COOKIE_ECHO will only confirm the address it sent the INIT_ACK to.

So, we can have a situation where the INIT sender can start to
use secondary paths without the need to send HEARTBEAT. This patch
allows DATA/SACK packets to create new connection tracking entry.

A new state has been added to indicate that a DATA/SACK chunk has
been seen in the original direction - SCTP_CONNTRACK_DATA_SENT.
State transitions mostly follows the HEARTBEAT_SENT, except on
receiving HEARTBEAT/HEARTBEAT_ACK/DATA/SACK in the reply direction.

State transitions in original direction:
- DATA_SENT behaves similar to HEARTBEAT_SENT for all chunks,
   except that it remains in DATA_SENT on receving HEARTBEAT,
   HEARTBEAT_ACK/DATA/SACK chunks
State transitions in reply direction:
- DATA_SENT behaves similar to HEARTBEAT_SENT for all chunks,
   except that it moves to HEARTBEAT_ACKED on receiving
   HEARTBEAT/HEARTBEAT_ACK/DATA/SACK chunks

Note: This patch still doesn't solve the problem when the SCTP
endpoint decides to use primary paths for association establishment
but uses a secondary path for association shutdown. We still have
to depend on timeout for connections to expire in such a case.

d8ba8ba4c8 KVM: x86/xen: Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured 
Closer inspection of the Xen code shows that we aren't supposed to be
using the XEN_RUNSTATE_UPDATE flag unconditionally. It should be
explicitly enabled by guests through the HYPERVISOR_vm_assist hypercall.
If we randomly set the top bit of ->state_entry_time for a guest that
hasn't asked for it and doesn't expect it, that could make the runtimes
fail to add up and confuse the guest. Without the flag it's perfectly
safe for a vCPU to read its own vcpu_runstate_info; just not for one
vCPU to read *another's*.

I briefly pondered adding a word for the whole set of VMASST_TYPE_*
flags but the only one we care about for HVM guests is this, so it
seemed a bit pointless.

0871561055 misc: fastrpc: Add support for audiopd 
In order to be able to start the adsp listener for audiopd using adsprpcd,
we need to add the corresponding ioctl for creating a static process.
On that ioctl call we need to allocate the heap. Allocating the heap needs
to be happening only once and needs to be kept between different device
open calls, so attach it to the channel context to make sure that remains
until the RPMSG driver is removed. Then, if there are any VMIDs associated
with the static ADSP process, do a call to SCM to assign it.
And then, send all the necessary info related to heap to the DSP.

by the DVB-C2 (ETSI EN 302 769) and DVB-S2X (ETSI EN 302 307-2)
standards to be ready for frontend drivers for such receivers.

While most parameters will be "read-only" due to being autodetected by
the receiver and only being reported back for informational purposes,
the addition of SYS_DVBC2 to the delivery systems enum is required,
because there are DVB-C2 capable receivers which are not capable of
DVB-C/C2 autodetection and thus need this enum value to be explicitly
instructed to search for a DVB-C2 signal.

As for DVB-S2X, as that is an extension to DVB-S2, the same delivery
system enum as for DVB-S2 can be used.

Add the additional enum values and comments to the documentation.

1dbb4f0235 virt: acrn: Mark the uuid field as unused 
After the commits for userspace (see Link tags below) the uuid field
is not being used in the ACRN code. Update kernel to reflect these
changes, i.e. do the following:
- adding a comment explaining that it's not used anymore
- replacing the specific type by a raw buffer
- updating the example code accordingly

The advertised field confused users and actually never been used.
So the wrong part here is that kernel puts something which userspace
never used and hence this may confuse a reader of this code.

Note, that there is only a single tool that had been prepared a year
ago for these forthcoming changes in the kernel.

fb491d5500 KVM: s390: pv: asynchronous destroy for reboot 
Until now, destroying a protected guest was an entirely synchronous
operation that could potentially take a very long time, depending on
the size of the guest, due to the time needed to clean up the address
space from protected pages.

This patch implements an asynchronous destroy mechanism, that allows a
protected guest to reboot significantly faster than previously.

This is achieved by clearing the pages of the old guest in background.
In case of reboot, the new guest will be able to run in the same
address space almost immediately.

The old protected guest is then only destroyed when all of its memory
has been destroyed or otherwise made non protected.

Two new PV commands are added for the KVM_S390_PV_COMMAND ioctl:

KVM_PV_ASYNC_CLEANUP_PREPARE: set aside the current protected VM for
later asynchronous teardown. The current KVM VM will then continue
immediately as non-protected. If a protected VM had already been
set aside for asynchronous teardown, but without starting the teardown
process, this call will fail. There can be at most one VM set aside at
any time. Once it is set aside, the protected VM only exists in the
context of the Ultravisor, it is not associated with the KVM VM
anymore. Its protected CPUs have already been destroyed, but not its
memory. This command can be issued again immediately after starting
KVM_PV_ASYNC_CLEANUP_PERFORM, without having to wait for completion.

KVM_PV_ASYNC_CLEANUP_PERFORM: tears down the protected VM previously
set aside using KVM_PV_ASYNC_CLEANUP_PREPARE. Ideally the
KVM_PV_ASYNC_CLEANUP_PERFORM PV command should be issued by userspace
from a separate thread. If a fatal signal is received (or if the
process terminates naturally), the command will terminate immediately
without completing. All protected VMs whose teardown was interrupted
will be put in the need_cleanup list. The rest of the normal KVM
teardown process will take care of properly cleaning up all remaining
protected VMs, including the ones on the need_cleanup list.

153524053b fuse: allow non-extending parallel direct writes on the same file 
In general, as of now, in FUSE, direct writes on the same file are
serialized over inode lock i.e we hold inode lock for the full duration of
the write request.  I could not find in fuse code and git history a comment
which clearly explains why this exclusive lock is taken for direct writes.
Following might be the reasons for acquiring an exclusive lock but not be
limited to

 1) Our guess is some USER space fuse implementations might be relying on
    this lock for serialization.

 2) The lock protects against file read/write size races.

 3) Ruling out any issues arising from partial write failures.

This patch relaxes the exclusive lock for direct non-extending writes only.
File size extending writes might not need the lock either, but we are not
entirely sure if there is a risk to introduce any kind of regression.
Furthermore, benchmarking with fio does not show a difference between patch
versions that take on file size extension a) an exclusive lock and b) a
shared lock.

A possible example of an issue with i_size extending writes are write error
cases.  Some writes might succeed and others might fail for file system
internal reasons - for example ENOSPACE.  With parallel file size extending
writes it _might_ be difficult to revert the action of the failing write,
especially to restore the right i_size.

With these changes, we allow non-extending parallel direct writes on the
same file with the help of a flag called FOPEN_PARALLEL_DIRECT_WRITES.  If
this flag is set on the file (flag is passed from libfuse to fuse kernel as
part of file open/create), we do not take exclusive lock anymore, but
instead use a shared lock that allows non-extending writes to run in
parallel.  FUSE implementations which rely on this inode lock for
serialization can continue to do so and serialized direct writes are still
the default.  Implementations that do not do write serialization need to be
updated and need to set the FOPEN_PARALLEL_DIRECT_WRITES flag in their file
open/create reply.

On patch review there were concerns that network file systems (or vfs
multiple mounts of the same file system) might have issues with parallel
writes.  We believe this is not the case, as this is just a local lock,
which network file systems could not rely on anyway.  I.e. this lock is
just for local consistency.

4f8d37020e fuse: add "expire only" mode to FUSE_NOTIFY_INVAL_ENTRY 
Add a flag to entry expiration that lets the filesystem expire a dentry
without kicking it out from the cache immediately.

This makes a difference for overmounted dentries, where plain invalidation
would detach all submounts before dropping the dentry from the cache.  If
only expiry is set on the dentry, then any overmounts are left alone and
until ->d_revalidate() is called.

Note: ->d_revalidate() is not called for the case of following a submount,
so invalidation will only be triggered for the non-overmounted case.  The
dentry could also be mounted in a different mount instance, in which case
any submounts will still be detached.

caf1aeaffc eventpoll: add EPOLL_URING_WAKE poll wakeup flag 
We can have dependencies between epoll and io_uring. Consider an epoll
context, identified by the epfd file descriptor, and an io_uring file
descriptor identified by iofd. If we add iofd to the epfd context, and
arm a multishot poll request for epfd with iofd, then the multishot
poll request will repeatedly trigger and generate events until terminated
by CQ ring overflow. This isn't a desired behavior.

Add EPOLL_URING so that io_uring can pass it in as part of the poll wakeup
key, and io_uring can check for that to detect a potential recursive
invocation.

0c5e259b06 RDMA/hns: Fix incorrect sge nums calculation 
The user usually configures the number of sge through the max_send_sge
parameter when creating qp, and configures the maximum size of inline data
that can be sent through max_inline_data. Inline uses sge to fill data to
send. Expect the following:

1) When the sge space cannot hold inline data, the sge space needs to be
   expanded to accommodate all inline data

2) When the sge space is enough to accommodate inline data, the upper
   limit of inline data can be increased so that users can send larger
   inline data

Currently case one is not implemented. When the inline data is larger than
the sge space, an error of insufficient sge space occurs.  This part of
the code needs to be reimplemented according to the expected rules. The
calculation method of sge num is modified to take the maximum value of
max_send_sge and the sge for max_inline_data to solve this problem.

f20a0a0519 ethtool: doc: clarify what drivers can implement in their get_drvinfo() 
Many of the drivers which implement ethtool_ops::get_drvinfo() will
prints the .driver, .version or .bus_info of struct ethtool_drvinfo.
To have a glance of current state, do:

  $ git grep -W "get_drvinfo(struct"

Printing in those three fields is useless because:

  - since [1], the driver version should be the kernel version (at
    least for upstream drivers). Arguably, out of tree drivers might
    still want to set a custom version, but out of tree is not our
    focus.

  - since [2], the core is able to provide default values for .driver
    and .bus_info.

In summary, drivers may provide .fw_version and .erom_version, the
rest is expected to be done by the core.

In struct ethtool_ops doc from linux/ethtool: rephrase field
get_drvinfo() doc to discourage developers from implementing this
callback.

In struct ethtool_drvinfo doc from uapi/linux/ethtool.h: remove the
paragraph mentioning what drivers should do. Rationale: no need to
repeat what is already written in struct ethtool_ops doc. But add a
note that .fw_version and .erom_version are driver defined.

Also update the dummy driver and simply remove the callback in order
not to confuse the newcomers: most of the drivers will not need this
callback function any more.

6c8c1406a6 virt: Add TDX guest driver 
TDX guest driver exposes IOCTL interfaces to service TDX guest
user-specific requests. Currently, it is only used to allow the user to
get the TDREPORT to support TDX attestation.

Details about the TDX attestation process are documented in
Documentation/x86/tdx.rst, and the IOCTL details are documented in
Documentation/virt/coco/tdx-guest.rst.

Operations like getting TDREPORT involves sending a blob of data as
input and getting another blob of data as output. It was considered
to use a sysfs interface for this, but it doesn't fit well into the
standard sysfs model for configuring values. It would be possible to
do read/write on files, but it would need multiple file descriptors,
which would be somewhat messy. IOCTLs seem to be the best fitting
and simplest model for this use case. The AMD sev-guest driver also
uses the IOCTL interface to support attestation.

This is because we try to copy the whole ip/ip6 address to the flow_key,
while we only point the to ip/ip6 saddr. Note that since these are UAPI
headers, __struct_group() is used to avoid the compiler warnings.

f0c5941ff5 bpf: Support bpf_list_head in map values 
Add the support on the map side to parse, recognize, verify, and build
metadata table for a new special field of the type struct bpf_list_head.
To parameterize the bpf_list_head for a certain value type and the
list_node member it will accept in that value type, we use BTF
declaration tags.

The definition of bpf_list_head in a map value will be done as follows:

struct foo {
	struct bpf_list_node node;
	int data;
};

struct map_value {
	struct bpf_list_head head __contains(foo, node);
};

Then, the bpf_list_head only allows adding to the list 'head' using the
bpf_list_node 'node' for the type struct foo.

The 'contains' annotation is a BTF declaration tag composed of four
parts, "contains:name:node" where the name is then used to look up the
type in the map BTF, with its kind hardcoded to BTF_KIND_STRUCT during
the lookup. The node defines name of the member in this type that has
the type struct bpf_list_node, which is actually used for linking into
the linked list. For now, 'kind' part is hardcoded as struct.

This allows building intrusive linked lists in BPF, using container_of
to obtain pointer to entry, while being completely type safe from the
perspective of the verifier. The verifier knows exactly the type of the
nodes, and knows that list helpers return that type at some fixed offset
where the bpf_list_node member used for this list exists. The verifier
also uses this information to disallow adding types that are not
accepted by a certain list.

For now, no elements can be added to such lists. Support for that is
coming in future patches, hence draining and freeing items is done with
a TODO that will be resolved in a future patch.

Note that the bpf_list_head_free function moves the list out to a local
variable under the lock and releases it, doing the actual draining of
the list items outside the lock. While this helps with not holding the
lock for too long pessimizing other concurrent list operations, it is
also necessary for deadlock prevention: unless every function called in
the critical section would be notrace, a fentry/fexit program could
attach and call bpf_map_update_elem again on the map, leading to the
same lock being acquired if the key matches and lead to a deadlock.
While this requires some special effort on part of the BPF programmer to
trigger and is highly unlikely to occur in practice, it is always better
if we can avoid such a condition.

While notrace would prevent this, doing the draining outside the lock
has advantages of its own, hence it is used to also fix the deadlock
related problem.

9bb053490f bpf: Add hwtstamp field for the sockops prog 
The bpf-tc prog has already been able to access the
skb_hwtstamps(skb)->hwtstamp.  This patch extends the same hwtstamp
access to the sockops prog.

In sockops, the skb is also available to the bpf prog during
the BPF_SOCK_OPS_PARSE_HDR_OPT_CB event.  There is a use case
that the hwtstamp will be useful to the sockops prog to better
measure the one-way-delay when the sender has put the tx
timestamp in the tcp header option.

ASoC: Set BQ parameters for some Dell models 
There are some Dell SKUs that need to set the parameters of the
crossover filter (biquad).  Each amplifier connects to one tweeter
speaker and one woofer speaker.  We should control HPF/LPF to output the
proper frequency for the different speakers.  If the codec driver got
the BQ parameters from the device property, it will apply these
parameters to the hardware.

86bdf3ebcf KVM: Support dirty ring in conjunction with bitmap 
ARM64 needs to dirty memory outside of a VCPU context when VGIC/ITS is
enabled. It's conflicting with that ring-based dirty page tracking always
requires a running VCPU context.

Introduce a new flavor of dirty ring that requires the use of both VCPU
dirty rings and a dirty bitmap. The expectation is that for non-VCPU
sources of dirty memory (such as the VGIC/ITS on arm64), KVM writes to
the dirty bitmap. Userspace should scan the dirty bitmap before migrating
the VM to the target.

Use an additional capability to advertise this behavior. The newly added
capability (KVM_CAP_DIRTY_LOG_RING_WITH_BITMAP) can't be enabled before
KVM_CAP_DIRTY_LOG_RING_ACQ_REL on ARM64. In this way, the newly added
capability is treated as an extension of KVM_CAP_DIRTY_LOG_RING_ACQ_REL.

d1a372af1c drm/amdgpu: Set MTYPE in PTE based on BO flags 
The same BO may need different MTYPEs and SNOOP flags in PTEs depending
on its current location relative to the mapping GPU. Setting MTYPEs from
clients ahead of time is not practical for coherent memory sharing.
Instead determine the correct MTYPE for the desired coherence model and
current BO location when updating the page tables.

To maintain backwards compatibility with MTYPE-selection in
AMDGPU_VA_OP_MAP, the coherence-model-based MTYPE selection is only
applied if it chooses an MTYPE other than MTYPE_NC (the default).

Add two AMDGPU_GEM_CREATE_... flags to indicate the coherence model. The
default if no flag is specified is non-coherent (i.e. coarse-grained
coherent at dispatch boundaries).

Update amdgpu_amdkfd_gpuvm.c to use this new method to choose the
correct MTYPE depending on the current memory location.

v2:
* check that bo is not NULL (e.g. PRT mappings)
* Fix missing ~ bitmask in gmc_v11_0.c
v3:
* squash in "drm/amdgpu: Inherit coherence flags on dmabuf import"

include/uapi/linux/swab: Fix potentially missing __always_inline 
Commit bc27fb68aa ("include/uapi/linux/byteorder, swab: force inlining
of some byteswap operations") added __always_inline to swab functions
and commit 283d757378 ("uapi/linux/stddef.h: Provide __always_inline to
userspace headers") added a definition of __always_inline for use in
exported headers when the kernel's compiler.h is not available.

However, since swab.h does not include stddef.h, if the header soup does
not indirectly include it, the definition of __always_inline is missing,
resulting in a compilation failure, which was observed compiling the
perf tool using exported headers containing this commit:

In file included from /usr/include/linux/byteorder/little_endian.h:12:0,
                 from /usr/include/asm/byteorder.h:14,
                 from tools/include/uapi/linux/perf_event.h:20,
                 from perf.h:8,
                 from builtin-bench.c:18:
/usr/include/linux/swab.h:160:8: error: unknown type name `__always_inline'
 static __always_inline __u16 __swab16p(const __u16 *p)

Fix this by replacing the inclusion of linux/compiler.h with
linux/stddef.h to ensure that we pick up that definition if required,
without relying on it's indirect inclusion. compiler.h is then included
indirectly, via stddef.h.

This patch is to add helper support in act_ct for OVS actions=ct(alg=xxx)

The difference is when adding TC actions family and proto cannot be got
from the filter/match, other than helper name in tb[TCA_CT_HELPER_NAME],
we also need to send the family in tb[TCA_CT_HELPER_FAMILY] and the
proto in tb[TCA_CT_HELPER_PROTO] to kernel.

9a0f830f80 ethtool: linkstate: add a statistic for PHY down events 
The previous attempt to augment carrier_down (see Link)
was not met with much enthusiasm so let's do the simple
thing of exposing what some devices already maintain.
Add a common ethtool statistic for link going down.
Currently users have to maintain per-driver mapping
to extract the right stat from the vendor-specific ethtool -S
stats. carrier_down does not fit the bill because it counts
a lot of software related false positives.

Add the statistic to the extended link state API to steer
vendors towards implementing all of it.

Implement for bnxt and all Linux-controlled PHYs. mlx5 and (possibly)
enic also have a counter for this but I leave the implementation
to their maintainers.

ASoC: SOF: Add support to parse pin binding array from topology 
Add support for parsing sink/source pin binding array
per widget from topology. The pin binding arrays will
be used to determine the source and sink queue IDs during
widget binding for widget that requires special pin binding.

An example of widget that requires special pin binding is
the smart amplifier widget, its feedback sink pin has to be
connected to a capture DAI copier for codec feedback, while
the other sink pin has to be connected to a host DAI copier.
Pin ID is required during widget binding for correct route setup.

Conversely, the pin ID for 'generic' pins is not defined in the
topology and will be allocated by the kernel dynamically. When
only one pin is supported, the pin ID shall always be zero. When
more than one pin is supported, the pin ID is determined with the
ID allocation mechanism in the kernel.

d4b9fd006f media: aspeed: Support aspeed mode to reduce compressed data 
aspeed supports differential jpeg format which only compress the parts
which are changed. In this way, it reduces both the amount of data to be
transferred by network and those to be decoded on the client side.

2 new ctrls are added:
* Aspeed HQ Mode: to control aspeed's high quality(2-pass) compression mode
  This only works with yuv444 subsampling.
* Aspeed HQ Quality: to control the quality of aspeed's HQ mode
  only useful if Aspeed HQ mode is enabled

Aspeed JPEG Format requires an additional buffer, called bcd, to store
the information about which macro block in the new frame is different
from the previous one.

To have bcd correctly working, we need to swap the buffers for src0/1 to
make src1 refer to previous frame and src0 to the coming new frame.

a35ec8e38c bridge: Add MAC Authentication Bypass (MAB) support 
Hosts that support 802.1X authentication are able to authenticate
themselves by exchanging EAPOL frames with an authenticator (Ethernet
bridge, in this case) and an authentication server. Access to the
network is only granted by the authenticator to successfully
authenticated hosts.

The above is implemented in the bridge using the "locked" bridge port
option. When enabled, link-local frames (e.g., EAPOL) can be locally
received by the bridge, but all other frames are dropped unless the host
is authenticated. That is, unless the user space control plane installed
an FDB entry according to which the source address of the frame is
located behind the locked ingress port. The entry can be dynamic, in
which case learning needs to be enabled so that the entry will be
refreshed by incoming traffic.

There are deployments in which not all the devices connected to the
authenticator (the bridge) support 802.1X. Such devices can include
printers and cameras. One option to support such deployments is to
unlock the bridge ports connecting these devices, but a slightly more
secure option is to use MAB. When MAB is enabled, the MAC address of the
connected device is used as the user name and password for the
authentication.

For MAB to work, the user space control plane needs to be notified about
MAC addresses that are trying to gain access so that they will be
compared against an allow list. This can be implemented via the regular
learning process with the sole difference that learned FDB entries are
installed with a new "locked" flag indicating that the entry cannot be
used to authenticate the device. The flag cannot be set by user space,
but user space can clear the flag by replacing the entry, thereby
authenticating the device.

Locked FDB entries implement the following semantics with regards to
roaming, aging and forwarding:

1. Roaming: Locked FDB entries can roam to unlocked (authorized) ports,
   in which case the "locked" flag is cleared. FDB entries cannot roam
   to locked ports regardless of MAB being enabled or not. Therefore,
   locked FDB entries are only created if an FDB entry with the given {MAC,
   VID} does not already exist. This behavior prevents unauthenticated
   devices from disrupting traffic destined to already authenticated
   devices.

2. Aging: Locked FDB entries age and refresh by incoming traffic like
   regular entries.

3. Forwarding: Locked FDB entries forward traffic like regular entries.
   If user space detects an unauthorized MAC behind a locked port and
   wishes to prevent traffic with this MAC DA from reaching the host, it
   can do so using tc or a different mechanism.

Enable the above behavior using a new bridge port option called "mab".
It can only be enabled on a bridge port that is both locked and has
learning enabled. Locked FDB entries are flushed from the port once MAB
is disabled. A new option is added because there are pure 802.1X
deployments that are not interested in notifications about locked FDB
entries.

6182d5875c net: dcb: add new apptrust attribute 
Add new apptrust extension attributes to the 8021Qaz APP managed object.

Two new attributes, DCB_ATTR_DCB_APP_TRUST_TABLE and
DCB_ATTR_DCB_APP_TRUST, has been added. Trusted selectors are passed in
the nested attribute DCB_ATTR_DCB_APP_TRUST, in order of precedence.

The new attributes are meant to allow drivers, whose hw supports the
notion of trust, to be able to set whether a particular app selector is
trusted - and in which order.

ec32c0c42d net: dcb: add new pcp selector to app object 
Add new PCP selector for the 8021Qaz APP managed object.

As the PCP selector is not part of the 8021Qaz standard, a new non-std
extension attribute DCB_ATTR_DCB_APP has been introduced. Also two
helper functions to translate between selector and app attribute type
has been added. The new selector has been given a value of 255, to
minimize the risk of future overlap of std- and non-std attributes.

The new DCB_ATTR_DCB_APP is sent alongside the ieee std attribute in the
app table. This means that the dcb_app struct can now both contain std-
and non-std app attributes. Currently there is no overlap between the
selector values of the two attributes.

The purpose of adding the PCP selector, is to be able to offload
PCP-based queue classification to the 8021Q Priority Code Point table,
see 6.9.3 of IEEE Std 802.1Q-2018.

PCP and DEI is encoded in the protocol field as 8*dei+pcp, so that a
mapping of PCP 2 and DEI 1 to priority 3 is encoded as {255, 10, 3}.

58ba426388 net/packet: add PACKET_FANOUT_FLAG_IGNORE_OUTGOING 
Extend packet socket option PACKET_IGNORE_OUTGOING to fanout groups.

The socket option sets ptype.ignore_outgoing, which makes
dev_queue_xmit_nit skip the socket.

When the socket joins a fanout group, the option is not reflected in
the struct ptype of the group. dev_queue_xmit_nit only tests the
fanout ptype, so the flag is ignored once a socket joins a
fanout group.

Inheriting the option from a socket would change established behavior.
Different sockets in the group can set different flags, and can also
change them at runtime.

Testing in packet_rcv_fanout defeats the purpose of the original
patch, which is to avoid skb_clone in dev_queue_xmit_nit (esp. for
MSG_ZEROCOPY packets).

Instead, introduce a new fanout group flag with the same behavior.

Tested with https://github.com/wdebruij/kerneltools/blob/master/tests/test_psock_fanout_ignore_outgoing.c

AudioReach Modules can connect to other modules using source and
destination port, and each module in theory can support up to 255 port
connections. But in practice this limit is at max 8 ports at a time.
So add support for allowing multiple port connections.

This support is needed for more detailed graphs like ECNS, speaker

7984ceb134 crypto: af_alg - Support symmetric encryption via keyring keys 
We want to leverage keyring to store sensitive keys, and then use those
keys for symmetric encryption via the crypto API. Among the key types we
wish to support are: user, logon, encrypted, and trusted.

User key types are already able to have their data copied to user space,
but logon does not support this. Further, trusted and encrypted keys will
return their encrypted data back to user space on read, which does not
make them ideal for symmetric encryption.

To support symmetric encryption for these key types, add a new
ALG_SET_KEY_BY_KEY_SERIAL setsockopt() option to the crypto API. This
allows users to pass a key_serial_t to the crypto API to perform
symmetric encryption. The behavior is the same as ALG_SET_KEY, but
the crypto key data is copied in kernel space from a keyring key,
which allows for the support of logon, encrypted, and trusted key types.

Keyring keys must have the KEY_(POS|USR|GRP|OTH)_SEARCH permission set
to leverage this feature. This follows the asymmetric_key type where key
lookup calls eventually lead to keyring_search_rcu() without the
KEYRING_SEARCH_NO_CHECK_PERM flag set.

12dee519d4 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next 
Pablo Neira Ayuso says:

====================
Netfilter updates for net-next

1) Move struct nft_payload_set definition to .c file where it is
   only used.

2) Shrink transport and inner header offset fields in the nft_pktinfo
   structure to 16-bits, from Florian Westphal.

3) Get rid of nft_objref Kbuild toggle, make it built-in into
   nf_tables. This expression is used to instantiate conntrack helpers
   in nftables. After removing the conntrack helper auto-assignment
   toggle it this feature became more important so move it to the nf_tables
   core module. Also from Florian.

4) Extend the existing function to calculate payload inner header offset
   to deal with the GRE and IPIP transport protocols.

6) Add inner expression support for nf_tables. This new expression
   provides a packet parser for tunneled packets which uses a userspace
   description of the expected inner headers. The inner expression
   invokes the payload expression (via direct call) to match on the
   inner header protocol fields using the inner link, network and
   transport header offsets.

   An example of the bytecode generated from userspace to match on
   IP source encapsulated in a VxLAN packet:

   # nft --debug=netlink add rule netdev x y udp dport 4789 vxlan ip saddr 1.2.3.4
     netdev x y
       [ meta load l4proto => reg 1 ]
       [ cmp eq reg 1 0x00000011 ]
       [ payload load 2b @ transport header + 2 => reg 1 ]
       [ cmp eq reg 1 0x0000b512 ]
       [ inner type vxlan hdrsize 8 flags f [ meta load protocol => reg 1 ] ]
       [ cmp eq reg 1 0x00000008 ]
       [ inner type vxlan hdrsize 8 flags f [ payload load 4b @ network header + 12 => reg 1 ] ]
       [ cmp eq reg 1 0x04030201 ]

7) Store inner link, network and transport header offsets in percpu
   area to parse inner packet header once only. Matching on a different
   tunnel type invalidates existing offsets in the percpu area and it
   invokes the inner tunnel parser again.

8) Add support for inner meta matching. This support for
   NFTA_META_PROTOCOL, which specifies the inner ethertype, and
   NFT_META_L4PROTO, which specifies the inner transport protocol.

9) Extend nft_inner to parse GENEVE optional fields to calculate the
   link layer offset.

10) Update inner expression so tunnel offset points to GRE header
    to normalize tunnel header handling. This also allows to perform
    different interpretations of the GRE header from userspace.

* git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next:
  netfilter: nft_inner: set tunnel offset to GRE header offset
  netfilter: nft_inner: add geneve support
  netfilter: nft_meta: add inner match support
  netfilter: nft_inner: add percpu inner context
  netfilter: nft_inner: support for inner tunnel header matching
  netfilter: nft_payload: access ipip payload for inner offset
  netfilter: nft_payload: access GRE payload via inner offset
  netfilter: nft_objref: make it builtin

bc7ed4d308 drm/i915/perf: Apply Wa_18013179988 
OA reports in the OA buffer contain an OA timestamp field that helps
user calculate delta between 2 OA reports. The calculation relies on the
CS timestamp frequency to convert the timestamp value to nanoseconds.
The CS timestamp frequency is a function of the CTC_SHIFT value in
RPM_CONFIG0.

In DG2, OA unit assumes that the CTC_SHIFT is 3, instead of using the
actual value from RPM_CONFIG0. At the user level, this results in an
error in calculating delta between 2 OA reports since the OA timestamp
is not shifted in the same manner as CS timestamp. Also the periodicity
of the reports is different from what the user configured because of
mismatch in the CS and OA frequencies.

The issue also affects MI_REPORT_PERF_COUNT command.

To resolve this, return actual OA timestamp frequency to the user in
i915_getparam_ioctl, so that user can calculate the right OA exponent as
well as interpret the reports correctly.

c4bcfb38a9 bpf: Implement cgroup storage available to non-cgroup-attached bpf progs 
Similar to sk/inode/task storage, implement similar cgroup local storage.

There already exists a local storage implementation for cgroup-attached
bpf programs.  See map type BPF_MAP_TYPE_CGROUP_STORAGE and helper
bpf_get_local_storage(). But there are use cases such that non-cgroup
attached bpf progs wants to access cgroup local storage data. For example,
tc egress prog has access to sk and cgroup. It is possible to use
sk local storage to emulate cgroup local storage by storing data in socket.
But this is a waste as it could be lots of sockets belonging to a particular
cgroup. Alternatively, a separate map can be created with cgroup id as the key.
But this will introduce additional overhead to manipulate the new map.
A cgroup local storage, similar to existing sk/inode/task storage,
should help for this use case.

The life-cycle of storage is managed with the life-cycle of the
cgroup struct.  i.e. the storage is destroyed along with the owning cgroup
with a call to bpf_cgrp_storage_free() when cgroup itself
is deleted.

The userspace map operations can be done by using a cgroup fd as a key
passed to the lookup, update and delete operations.

Typically, the following code is used to get the current cgroup:
    struct task_struct *task = bpf_get_current_task_btf();
    ... task->cgroups->dfl_cgrp ...
and in structure task_struct definition:
    struct task_struct {
        ....
        struct css_set __rcu            *cgroups;
        ....
    }
With sleepable program, accessing task->cgroups is not protected by rcu_read_lock.
So the current implementation only supports non-sleepable program and supporting
sleepable program will be the next step together with adding rcu_read_lock
protection for rcu tagged structures.

Since map name BPF_MAP_TYPE_CGROUP_STORAGE has been used for old cgroup local
storage support, the new map name BPF_MAP_TYPE_CGRP_STORAGE is used
for cgroup storage available to non-cgroup-attached bpf programs. The old
cgroup storage supports bpf_get_local_storage() helper to get the cgroup data.
The new cgroup storage helper bpf_cgrp_storage_get() can provide similar
functionality. While old cgroup storage pre-allocates storage memory, the new
mechanism can also pre-allocate with a user space bpf_map_update_elem() call
to avoid potential run-time memory allocation failure.
Therefore, the new cgroup storage can provide all functionality w.r.t.
the old one. So in uapi bpf.h, the old BPF_MAP_TYPE_CGROUP_STORAGE is alias to
BPF_MAP_TYPE_CGROUP_STORAGE_DEPRECATED to indicate the old cgroup storage can
be deprecated since the new one can provide the same functionality.

3a07327d10 netfilter: nft_inner: support for inner tunnel header matching 
This new expression allows you to match on the inner headers that are
encapsulated by any of the existing tunneling protocols.

This expression parses the inner packet to set the link, network and
transport offsets, so the existing expressions (with a few updates) can
be reused to match on the inner headers.

The inner expression supports for different tunnel combinations such as:

- ethernet frame over IPv4/IPv6 packet, eg. VxLAN.
- IPv4/IPv6 packet over IPv4/IPv6 packet, eg. IPIP.
- IPv4/IPv6 packet over IPv4/IPv6 + transport header, eg. GRE.
- transport header (ESP or SCTP) over transport header (usually UDP)

The following fields are used to describe the tunnel protocol:

- flags, which describe how to parse the inner headers:

  NFT_PAYLOAD_CTX_INNER_TUN, the tunnel provides its own header.
  NFT_PAYLOAD_CTX_INNER_ETHER, the ethernet frame is available as inner header.
  NFT_PAYLOAD_CTX_INNER_NH, the network header is available as inner header.
  NFT_PAYLOAD_CTX_INNER_TH, the transport header is available as inner header.

For example, VxLAN sets on all of these flags. While GRE only sets on
NFT_PAYLOAD_CTX_INNER_NH and NFT_PAYLOAD_CTX_INNER_TH. Then, ESP over
UDP only sets on NFT_PAYLOAD_CTX_INNER_TH.

The tunnel description is composed of the following attributes:

- header size: in case the tunnel comes with its own header, eg. VxLAN.

- type: this provides a hint to userspace on how to delinearize the rule.
  This is useful for VxLAN and Geneve since they run over UDP, since
  transport does not provide a hint. This is also useful in case hardware
  offload is ever supported. The type is not currently interpreted by the
  kernel.

- expression: currently only payload supported. Follow up patch adds
  also inner meta support which is required by autogenerated
  dependencies. The exthdr expression should be supported too
  at some point. There is a new inner_ops operation that needs to be
  set on to allow to use an existing expression from the inner expression.

This patch adds a new NFT_PAYLOAD_TUN_HEADER base which allows to match
on the tunnel header fields, eg. vxlan vni.

The payload expression is embedded into nft_inner private area and this
private data area is passed to the payload inner eval function via
direct call.

   - a DVB core security fix

   - lots of fixes and cleanups for atomisp staging driver

   - old drivers that are VB1 are being moved to staging to be
     deprecated

   - several driver updates - mostly for embedded systems, but there are
     also some things addressing issues with some PC webcams, in the UVC
     video driver"

d182bf156c usb: gadget: uvc: default the ctrl request interface offsets 
For the userspace it is needed to distinguish between requests for the
control or streaming interface. The userspace would have to parse the
configfs to know which interface index it has to compare the ctrl
requests against. Since the interface numbers are not fixed, e.g. for
composite gadgets, the interface offset depends on the setup.

The kernel has this information when handing over the ctrl request to
the userspace. This patch removes the offset from the interface numbers
and expose the default interface defines in the uapi g_uvc.h.

72655fb942 drm/panfrost: replace endian-specific types with native ones 
__le32 and __le64 types aren't portable and are not available on
FreeBSD (which uses the same uAPI).

Instead of attempting to always output little endian, just use native
endianness in the dumps. Tools can detect the endianness in use by
looking at the 'magic' field, but equally we don't expect big-endian to
be used with Mali (there are no known implementations out there).

7228d9d792 drm/panfrost: Remove type name from internal structs 
The two structs internal to struct panfrost_dump_object_header were
named, but sadly that is incompatible with C++, causing an error: "an
anonymous union may only have public non-static data members".

However nothing refers to struct pan_reg_hdr and struct pan_bomap_hdr
and there's no need to export these definitions, so lets drop them. This
fixes the C++ build error with the minimum change in userspace API.

0ec8ce0739 dmaengine: idxd: Do not enable user type Work Queue without Shared Virtual Addressing 
When the idxd_user_drv driver is bound to a Work Queue (WQ) device
without IOMMU or with IOMMU Passthrough without Shared Virtual
Addressing (SVA), the application gains direct access to physical
memory via the device by programming physical address to a submitted
descriptor. This allows direct userspace read and write access to
arbitrary physical memory. This is inconsistent with the security
goals of a good kernel API.

Unlike vfio_pci driver, the IDXD char device driver does not provide any
ways to pin user pages and translate the address from user VA to IOVA or
PA without IOMMU SVA. Therefore the application has no way to instruct the
device to perform DMA function. This makes the char device not usable for
normal application usage.

Since user type WQ without SVA cannot be used for normal application usage
and presents the security issue, bind idxd_user_drv driver and enable user
type WQ only when SVA is enabled (i.e. user PASID is enabled).

landlock: Support file truncation 
Introduce the LANDLOCK_ACCESS_FS_TRUNCATE flag for file truncation.

This flag hooks into the path_truncate, file_truncate and
file_alloc_security LSM hooks and covers file truncation using
truncate(2), ftruncate(2), open(2) with O_TRUNC, as well as creat().

This change also increments the Landlock ABI version, updates
corresponding selftests, and updates code documentation to document
the flag.

In security/security.c, allocate security blobs at pointer-aligned
offsets. This fixes the problem where one LSM's security blob can
shift another LSM's security blob to an unaligned address (reported
by Nathan Chancellor).

The following operations are restricted:

open(2): requires the LANDLOCK_ACCESS_FS_TRUNCATE right if a file gets
implicitly truncated as part of the open() (e.g. using O_TRUNC).

Notable special cases:
* open(..., O_RDONLY|O_TRUNC) can truncate files as well in Linux
* open() with O_TRUNC does *not* need the TRUNCATE right when it
  creates a new file.

truncate(2) (on a path): requires the LANDLOCK_ACCESS_FS_TRUNCATE
right.

ftruncate(2) (on a file): requires that the file had the TRUNCATE
right when it was previously opened. File descriptors acquired by
other means than open(2) (e.g. memfd_create(2)) continue to support
truncation with ftruncate(2).

We've added 33 non-merge commits during the last 14 day(s) which contain
a total of 31 files changed, 874 insertions(+), 538 deletions(-).

The main changes are:

1) Add RCU grace period chaining to BPF to wait for the completion
   of access from both sleepable and non-sleepable BPF programs,
   from Hou Tao & Paul E. McKenney.

2) Improve helper UAPI by explicitly defining BPF_FUNC_xxx integer
   values. In the wild we have seen OS vendors doing buggy backports
   where helper call numbers mismatched. This is an attempt to make
   backports more foolproof, from Andrii Nakryiko.

3) Add libbpf *_opts API-variants for bpf_*_get_fd_by_id() functions,
   from Roberto Sassu.

4) Fix libbpf's BTF dumper for structs with padding-only fields,
   from Eduard Zingerman.

5) Fix various libbpf bugs which have been found from fuzzing with
   malformed BPF object files, from Shung-Hsi Yu.

6) Clean up an unneeded check on existence of SSE2 in BPF x86-64 JIT,
   from Jie Meng.

7) Fix various ASAN bugs in both libbpf and selftests when running
   the BPF selftest suite on arm64, from Xu Kuohai.

8) Fix missing bpf_iter_vma_offset__destroy() call in BPF iter selftest
   and use in-skeleton link pointer to remove an explicit bpf_link__destroy(),
   from Jiri Olsa.

9) Fix BPF CI breakage by pointing to iptables-legacy instead of relying
   on symlinked iptables which got upgraded to iptables-nft,
   from Martin KaFai Lau.

10) Minor BPF selftest improvements all over the place, from various others.

d54576a074 drm/i915/uapi: expose GTT alignment 
On some platforms we potentially have different alignment restrictions
depending on the memory type. We also now have different alignment
restrictions for the same region across different kernel versions.
Extend the region query to return the minimum required GTT alignment.

Testcase: igt@gem_create@create-ext-placement-alignment
Testcase: igt@i915_query@query-regions-sanity-check

8133a6daad drm/i915: enable PS64 support for DG2 
It turns out that on production DG2/ATS HW we should have support for
PS64. This feature allows to provide a 64K TLB hint at the PTE level,
which is a lot more flexible than the current method of enabling 64K GTT
pages for the entire page-table, since that leads to all kinds of
annoying restrictions, as documented in:

commit caa574ffc4
Author: Matthew Auld <matthew.auld@intel.com>
Date:   Sat Feb 19 00:17:49 2022 +0530

    drm/i915/uapi: document behaviour for DG2 64K support

    On discrete platforms like DG2, we need to support a minimum page size
    of 64K when dealing with device local-memory. This is quite tricky for
    various reasons, so try to document the new implicit uapi for this.

With PS64, we can now drop the 2M GTT alignment restriction, and instead
only require 64K or larger when dealing with lmem. We still use the
compact-pt layout when possible, but only when we are certain that this
doesn't interfere with userspace.

Note that this is a change in uAPI behaviour, but hopefully shouldn't be
a concern (IGT is at least able to autodetect the alignment), since we
are only making the GTT alignment constraint less restrictive.

Based on a patch from CQ Tang.

v2: update the comment wrt scratch page
v3: (Nirmoy)
 - Fix the selftest to actually use the random size, plus some comment
   improvements, also drop the rem stuff.

d3cf405133 VFIO updates for v6.1-rc1 
- Prune private items from vfio_pci_core.h to a new internal header,
    fix missed function rename, and refactor vfio-pci interrupt defines.
    (Jason Gunthorpe)
 
  - Create consistent naming and handling of ioctls with a function per
    ioctl for vfio-pci and vfio group handling, use proper type args
    where available. (Jason Gunthorpe)
 
  - Implement a set of low power device feature ioctls allowing userspace
    to make use of power states such as D3cold where supported.
    (Abhishek Sahu)
 
  - Remove device counter on vfio groups, which had restricted the page
    pinning interface to singleton groups to account for limitations in
    the type1 IOMMU backend.  Document usage as limited to emulated IOMMU
    devices, ie. traditional mdev devices where this restriction is
    consistent.  (Jason Gunthorpe)
 
  - Correct function prefix in hisi_acc driver incurred during previous
    refactoring. (Shameer Kolothum)
 
  - Correct typo and remove redundant warning triggers in vfio-fsl driver.
    (Christophe JAILLET)
 
  - Introduce device level DMA dirty tracking uAPI and implementation in
    the mlx5 variant driver (Yishai Hadas & Joao Martins)
 
  - Move much of the vfio_device life cycle management into vfio core,
    simplifying and avoiding duplication across drivers.  This also
    facilitates adding a struct device to vfio_device which begins the
    introduction of device rather than group level user support and fills
    a gap allowing userspace identify devices as vfio capable without
    implicit knowledge of the driver. (Kevin Tian & Yi Liu)
 
  - Split vfio container handling to a separate file, creating a more
    well defined API between the core and container code, masking IOMMU
    backend implementation from the core, allowing for an easier future
    transition to an iommufd based implementation of the same.
    (Jason Gunthorpe)
 
  - Attempt to resolve race accessing the iommu_group for a device
    between vfio releasing DMA ownership and removal of the device from
    the IOMMU driver.  Follow-up with support to allow vfio_group to
    exist with NULL iommu_group pointer to support existing userspace
    use cases of holding the group file open.  (Jason Gunthorpe)
 
  - Fix error code and hi/lo register manipulation issues in the hisi_acc
    variant driver, along with various code cleanups. (Longfang Liu)
 
  - Fix a prior regression in GVT-g group teardown, resulting in
    unreleased resources. (Jason Gunthorpe)
 
  - A significant cleanup and simplification of the mdev interface,
    consolidating much of the open coded per driver sysfs interface
    support into the mdev core. (Christoph Hellwig)
 
  - Simplification of tracking and locking around vfio_groups that
    fall out from previous refactoring. (Jason Gunthorpe)
 
  - Replace trivial open coded f_ops tests with new helper.

228565100d vDPA: allow userspace to query features of a vDPA device 
This commit adds a new vDPA netlink attribution
VDPA_ATTR_VDPA_DEV_SUPPORTED_FEATURES. Userspace can query
features of vDPA devices through this new attr.

This commit invokes vdpa_config_ops.get_config()
rather than vdpa_get_config_unlocked() to read
the device config spcae, so no races in
vdpa_set_features_unlocked()

Userspace tool iproute2 example:
$ vdpa dev config show vdpa0
vdpa0: mac 00:e8:ca:11:be:05 link up link_announce false max_vq_pairs 4 mtu 1500
  negotiated_features MRG_RXBUF CTRL_VQ MQ VERSION_1 ACCESS_PLATFORM

d3dcbe24a0 USB/Thunderbolt changes for 6.1-rc1 
Here is the big set of USB and Thunderbolt driver changes for 6.1-rc1.
 
 Nothing major in here, lots of little things with new devices supported
 and updates for a few drivers.  Highlights include:
 	- thunderbolt/USB4 devices supported a bit better than before,
 	  and some new ids to enable new hardware devices
 	- USB gadget uvc updates for newer video formats and better v4l
 	  integration (the v4l portions were acked by those maintainers)
 	- typec updates for tiny issues and more typec drivers for new
 	  chips.
 	- xhci tiny updates for minor issues
 	- big usb-serial ftdi_sio driver update to handle new devices
 	  better
 	- lots of tiny dwc3 fixes and updates for the IP block that is
 	  showing up everywhere these days
 	- dts updates for new devices being supported
 	- other tiny janitorial and cleanups fixes for lots of different
 	  USB drivers.  Full details are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

Merge tag 'usb-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB / Thunderbolt updates from Greg KH:
 "Here is the big set of USB and Thunderbolt driver changes for 6.1-rc1.

  Nothing major in here, lots of little things with new devices
  supported and updates for a few drivers. Highlights include:

   - thunderbolt/USB4 devices supported a bit better than before, and
     some new ids to enable new hardware devices

   - USB gadget uvc updates for newer video formats and better v4l
     integration (the v4l portions were acked by those maintainers)

   - typec updates for tiny issues and more typec drivers for new chips.

   - xhci tiny updates for minor issues

   - big usb-serial ftdi_sio driver update to handle new devices better

   - lots of tiny dwc3 fixes and updates for the IP block that is
     showing up everywhere these days

   - dts updates for new devices being supported

   - other tiny janitorial and cleanups fixes for lots of different USB
     drivers. Full details are in the shortlog.

  All of these have been in linux-next for a while with no reported
  issues"

62e6e5940c SCSI misc on 20221007 
Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr,
 mpt3sas, target); the biggest change (from my biased viewpoint) being
 that the mpi3mr now attached to the SAS transport class, making it the
 first fusion type device to do so.  Beyond the usual bug fixing and
 security class reworks, there aren't a huge number of core changes.

Pull io_uring updates from Jens Axboe:

 - Add supported for more directly managed task_work running.

   This is beneficial for real world applications that end up issuing
   lots of system calls as part of handling work. Normal task_work will
   always execute as we transition in and out of the kernel, even for
   "unrelated" system calls. It's more efficient to defer the handling
   of io_uring's deferred work until the application wants it to be run,
   generally in batches.

   As part of ongoing work to write an io_uring network backend for
   Thrift, this has been shown to greatly improve performance. (Dylan)

 - Add IOPOLL support for passthrough (Kanchan)

 - Improvements and fixes to the send zero-copy support (Pavel)

90fea5a800 vdpa: device feature provisioning 
This patch allows the device features to be provisioned through
netlink. A new attribute is introduced to allow the userspace to pass
a 64bit device features during device adding.

This provides several advantages:

- Allow to provision a subset of the features to ease the cross vendor
  live migration.
- Better debug-ability for vDPA framework and parent.

This results in mismatch between transition disable policy

Pull btrfs updates from David Sterba:
 "There's a bunch of performance improvements, most notably the FIEMAP
  speedup, the new block group tree to speed up mount on large
  filesystems, more io_uring integration, some sysfs exports and the
  usual fixes and core updates.

  Summary:

  Performance:

   - outstanding FIEMAP speed improvement
      - algorithmic change how extents are enumerated leads to orders of
        magnitude speed boost (uncached and cached)
      - extent sharing check speedup (2.2x uncached, 3x cached)
      - add more cancellation points, allowing to interrupt seeking in
        files with large number of extents
      - more efficient hole and data seeking (4x uncached, 1.3x cached)
      - sample results:
	    256M, 32K extents:   4s ->  29ms  (~150x)
	    512M, 64K extents:  30s ->  59ms  (~550x)
	    1G,  128K extents: 225s -> 120ms (~1800x)

   - improved inode logging, especially for directories (on dbench
     workload throughput +25%, max latency -21%)

   - improved buffered IO, remove redundant extent state tracking,
     lowering memory consumption and avoiding rb tree traversal

   - add sysfs tunable to let qgroup temporarily skip exact accounting
     when deleting snapshot, leading to a speedup but requiring a rescan
     after that, will be used by snapper

   - support io_uring and buffered writes, until now it was just for
     direct IO, with the no-wait semantics implemented in the buffered
     write path it now works and leads to speed improvement in IOPS
     (2x), throughput (2.2x), latency (depends, 2x to 150x)

   - small performance improvements when dropping and searching for
     extent maps as well as when flushing delalloc in COW mode
     (throughput +5MB/s)

  User visible changes:

   - new incompatible feature block-group-tree adding a dedicated tree
     for tracking block groups, this allows a much faster load during
     mount and avoids seeking unlike when it's scattered in the extent
     tree items
      - this reduces mount time for many-terabyte sized filesystems
      - conversion tool will be provided so existing filesystem can also
        be updated in place
      - to reduce test matrix and feature combinations requires no-holes
        and free-space-tree (mkfs defaults since 5.15)

   - improved reporting of super block corruption detected by scrub

   - scrub also tries to repair super block and does not wait until next
     commit

   - discard stats and tunables are exported in sysfs
     (/sys/fs/btrfs/FSID/discard)

   - qgroup status is exported in sysfs
     (/sys/sys/fs/btrfs/FSID/qgroups/)

   - verify that super block was not modified when thawing filesystem

  Fixes:

   - FIEMAP fixes
      - fix extent sharing status, does not depend on the cached status
        where merged
      - flush delalloc so compressed extents are reported correctly

   - fix alignment of VMA for memory mapped files on THP

   - send: fix failures when processing inodes with no links (orphan
     files and directories)

   - fix race between quota enable and quota rescan ioctl

   - handle more corner cases for read-only compat feature verification

   - fix missed extent on fsync after dropping extent maps

  Core:

   - lockdep annotations to validate various transactions states and
     state transitions

   - preliminary support for fs-verity in send

   - more effective memory use in scrub for subpage where sector is
     smaller than page

   - block group caching progress logic has been removed, load is now
     synchronous

   - simplify end IO callbacks and bio handling, use chained bios
     instead of own tracking

   - add no-wait semantics to several functions (tree search, nocow,
     flushing, buffered write

   - cleanups and refactoring

  MM changes:

   - export balance_dirty_pages_ratelimited_flags"

43d3f3b94e drm/fourcc: add Vivante tile status modifiers 
The tile status modifiers can be combined with all of the usual
color buffer modifiers. When they are present an additional plane
is added to the surfaces to share the tile status buffer. The
TS modifiers describe the interpretation of the tag bits in this
buffer.

8a76145a2e bpf: explicitly define BPF_FUNC_xxx integer values 
Historically enum bpf_func_id's BPF_FUNC_xxx enumerators relied on
implicit sequential values being assigned by compiler. This is
convenient, as new BPF helpers are always added at the very end, but it
also has its downsides, some of them being:

  - with over 200 helpers now it's very hard to know what's each helper's ID,
    which is often important to know when working with BPF assembly (e.g.,
    by dumping raw bpf assembly instructions with llvm-objdump -d
    command). it's possible to work around this by looking into vmlinux.h,
    dumping /sys/btf/kernel/vmlinux, looking at libbpf-provided
    bpf_helper_defs.h, etc. But it always feels like an unnecessary step
    and one should be able to quickly figure this out from UAPI header.

  - when backporting and cherry-picking only some BPF helpers onto older
    kernels it's important to be able to skip some enum values for helpers
    that weren't backported, but preserve absolute integer IDs to keep BPF
    helper IDs stable so that BPF programs stay portable across upstream
    and backported kernels.

While neither problem is insurmountable, they come up frequently enough
and are annoying enough to warrant improving the situation. And for the
backporting the problem can easily go unnoticed for a while, especially
if backport is done with people not very familiar with BPF subsystem overall.

Anyways, it's easy to fix this by making sure that __BPF_FUNC_MAPPER
macro provides explicit helper IDs. Unfortunately that would potentially
break existing users that use UAPI-exposed __BPF_FUNC_MAPPER and are
expected to pass macro that accepts only symbolic helper identifier
(e.g., map_lookup_elem for bpf_map_lookup_elem() helper).

As such, we need to introduce a new macro (___BPF_FUNC_MAPPER) which
would specify both identifier and integer ID, but in such a way as to
allow existing __BPF_FUNC_MAPPER be expressed in terms of new
___BPF_FUNC_MAPPER macro. And that's what this patch is doing. To avoid
duplication and allow __BPF_FUNC_MAPPER stay *exactly* the same,
___BPF_FUNC_MAPPER accepts arbitrary "context" arguments, which can be
used to pass any extra macros, arguments, and whatnot. In our case we
use this to pass original user-provided macro that expects single
argument and __BPF_FUNC_MAPPER is using it's own three-argument
__BPF_FUNC_MAPPER_APPLY intermediate macro to impedance-match new and
old "callback" macros.

Once we resolve this, we use new ___BPF_FUNC_MAPPER to define enum
bpf_func_id with explicit values. The other users of __BPF_FUNC_MAPPER
in kernel (namely in kernel/bpf/disasm.c) are kept exactly the same both
as demonstration that backwards compat works, but also to avoid
unnecessary code churn.

Note that new ___BPF_FUNC_MAPPER() doesn't forcefully insert comma
between values, as that might not be appropriate in all possible cases
where ___BPF_FUNC_MAPPER might be used by users. This doesn't reduce
usability, as it's trivial to insert that comma inside "callback" macro.

To validate all the manually specified IDs are exactly right, we used
BTF to compare before and after values:

  $ bpftool btf dump file ~/linux-build/default/vmlinux | rg bpf_func_id -A 211 > after.txt
  $ git stash # stach UAPI changes
  $ make -j90
  ... re-building kernel without UAPI changes ...
  $ bpftool btf dump file ~/linux-build/default/vmlinux | rg bpf_func_id -A 211 > before.txt
  $ diff -u before.txt after.txt
  --- before.txt  2022-10-05 10:48:18.119195916 -0700
  +++ after.txt   2022-10-05 10:46:49.446615025 -0700
  @@ -1,4 +1,4 @@

          'BPF_FUNC_map_lookup_elem' val=1
          'BPF_FUNC_map_update_elem' val=2

As can be seen from diff above, the only thing that changed was resulting BTF
type ID of ENUM bpf_func_id, not any of the enumerators, their names or integer
values.

The only other place that needed fixing was scripts/bpf_doc.py used to generate
man pages and bpf_helper_defs.h header for libbpf and selftests. That script is
tightly-coupled to exact shape of ___BPF_FUNC_MAPPER macro definition, so had
to be trivially adapted.
