f176638af4 USB: Remove Wireless USB and UWB documentation
Support for Wireless USB and Ultra WideBand was removed in 2020 by
commit caa6772db4 ("Staging: remove wusbcore and UWB from the kernel
tree.").  But the documentation files were left behind.

Let's get rid of that out-of-date documentation.

f20765fdfd integrity: Always reference the blacklist keyring with appraisal
Commit 273df864cf ("ima: Check against blacklisted hashes for files with
modsig") introduced an appraise_flag option for referencing the blacklist
keyring.  Any matching binary found on this keyring fails signature
validation. This flag only works with module appended signatures.

An important part of a PKI infrastructure is to have the ability to do
revocation at a later time should a vulnerability be found.  Expand the
revocation flag usage to all appraisal functions. The flag is now
enabled by default. Setting the flag with an IMA policy has been
deprecated. Without a revocation capability like this in place, only
authenticity can be maintained. With this change, integrity can now be
achieved with digital signature based IMA appraisal.

7f48405c3c cpu/SMT: Allow enabling partial SMT states via sysfs
Add support to the /sys/devices/system/cpu/smt/control interface for
enabling a specified number of SMT threads per core, including partial
SMT states where not all threads are brought online.

The current interface accepts "on" and "off", to enable either 1 or all
SMT threads per core.

This commit allows writing an integer, between 1 and the number of SMT
threads supported by the machine. Writing 1 is a synonym for "off", 2 or
more enables SMT with the specified number of threads.

When reading the file, if all threads are online "on" is returned, to
avoid changing behaviour for existing users. If some other number of
threads is online then the integer value is returned.

Architectures like x86 only supporting 1 thread or all threads, should not
define CONFIG_SMT_NUM_THREADS_DYNAMIC. Architecture supporting partial SMT
states, like PowerPC, should define it.

c04e989484 xen: speed up grant-table reclaim
When a grant entry is still in use by the remote domain, Linux must put
it on a deferred list.  Normally, this list is very short, because
the PV network and block protocols expect the backend to unmap the grant
first.  However, Qubes OS's GUI protocol is subject to the constraints
of the X Window System, and as such winds up with the frontend unmapping
the window first.  As a result, the list can grow very large, resulting
in a massive memory leak and eventual VM freeze.

To partially solve this problem, make the number of entries that the VM
will attempt to free at each iteration tunable.  The default is still
10, but it can be overridden via a module parameter.

This is Cc: stable because (when combined with appropriate userspace
changes) it fixes a severe performance and stability problem for Qubes
OS users.

a85ff0db48 usb: gadget: midi2: More flexible MIDI 1.0 configuration
This patch allows users to set up MIDI 1.0 ports more flexibly.
Namely, instead of the fixed mapping only from FB 0, now multiple
block definitions are applied to build up the MIDI 1.0 mapping.

The each block config has midi1_first_group and midi1_num_groups
attributes, and those specify which Groups are used for MIDI 1.0.
Those fields must be within the UMP Groups defined in the block
itself.

29ee7a4ddd usb: gadget: midi2: Add configfs support
This patch adds the support of configfs to MIDI 2.0 function driver
for users to allow configuring the UMP Endpoint and Function Blocks
more flexibly.  The configuration is in a tree form.  The top-most
contains some card-level configurations.  UMP Endpoints are defined in
subdirectories (ep.0, ep.1, etc) that contain Endpoint-specific
configurations such as ep_name, etc.  And, UMP Function Blocks are
defined in the subdirectories (block.0, block.1, etc) under EP
subdirectory.  As default, the driver creates a single UMP Endpoint
(ep.0) and a single Function Block (block.0) to work in a minimalistic
manner.  User can modify those attributes freely to fit with the
demands.

When multiple Function Blocks are required, user can create another
directory as block.1, block.2, and so on (up to block.31).  A block.*
directory can be deleted dynamically, too.  A caveat is that the block
number has to be continuous.

Similarly, when multiple UMP Endpoints are required, user can create
another directory as ep.1, ep.2, up to ep.3.

Also, some driver behavior can be controlled in the card top-level
configs.  e.g. you can pass process_ump=0 to disable the processing of
UMP Stream messages.  This would be equivalent with the older MIDI 2.0
spec that doesn't support UMP v1.1 features.

The configfs interface checks upper- / lower-bound of input values,
and more sanity checks are performed at binding.

Attributes can't be changed any longer once when the instance is
linked to UDC.

5e1cd3e97e iio: Add event enums for running period and count
There are devices (such as Murata IRS-D200 PIR proximity sensor) that
check the data signal with a running period. I.e. for a specified time,
they count the number of conditions that have occurred, and then signal
if that is more than a specified amount.

`IIO_EV_INFO_PERIOD` resets when the condition no longer is true and is
therefore not suitable for these devices. Add a new `iio_event_info`
`IIO_EV_INFO_RUNNING_PERIOD` that can be used as a running period. Also
add a new `IIO_EV_INFO_RUNNING_COUNT` that can be used to specify the
number of conditions that must occur during this running period.

359b84f8db crypto: qat - add heartbeat feature
Under some circumstances, firmware in the QAT devices could become
unresponsive. The Heartbeat feature provides a mechanism to detect
unresponsive devices.

The QAT FW periodically writes to memory a set of counters that allow
to detect the liveness of a device. This patch adds logic to enable
the reporting of those counters, analyze them and report if a device
is alive or not.

In particular this adds
  (1) heartbeat enabling, reading and detection logic
  (2) reporting of heartbeat status and configuration via debugfs
  (3) documentation for the newly created sysfs entries
  (4) configuration of FW settings related to heartbeat, e.g. tick period
  (5) logic to convert time in ms (provided by the user) to clock ticks

This patch introduces a new folder in debugfs called heartbeat with the
following attributes:
 - status
 - queries_sent
 - queries_failed
 - config

All attributes except config are reading only. In particular:
 - `status` file returns 0 when device is operational and -1 otherwise.
 - `queries_sent` returns the total number of heartbeat queries sent.
 - `queries_failed` returns the total number of heartbeat queries failed.
 - `config` allows to adjust the frequency at which the firmware writes
   counters to memory. This period is given in milliseconds and it is
   fixed for GEN4 devices.

8974eb5882 x86/speculation: Add Gather Data Sampling mitigation
Gather Data Sampling (GDS) is a hardware vulnerability which allows
unprivileged speculative access to data which was previously stored in
vector registers.

Intel processors that support AVX2 and AVX512 have gather instructions
that fetch non-contiguous data elements from memory. On vulnerable
hardware, when a gather instruction is transiently executed and
encounters a fault, stale data from architectural or internal vector
registers may get transiently stored to the destination vector
register allowing an attacker to infer the stale data using typical
side channel techniques like cache timing attacks.

This mitigation is different from many earlier ones for two reasons.
First, it is enabled by default and a bit must be set to *DISABLE* it.
This is the opposite of normal mitigation polarity. This means GDS can
be mitigated simply by updating microcode and leaving the new control
bit alone.

Second, GDS has a "lock" bit. This lock bit is there because the
mitigation affects the hardware security features KeyLocker and SGX.
It needs to be enabled and *STAY* enabled for these features to be
mitigated against GDS.

The mitigation is enabled in the microcode by default. Disable it by
setting gather_data_sampling=off or by disabling all mitigations with
mitigations=off. The mitigation status can be checked by reading:

    /sys/devices/system/cpu/vulnerabilities/gather_data_sampling

d25f002575 Merge tag 'cxl-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
 "The highlights in terms of new functionality are support for the
  standard CXL Performance Monitor definition that appeared in CXL 3.0,
  support for device sanitization (wiping all data from a device),
  secure-erase (re-keying encryption of user data), and support for
  firmware update. The firmware update support is notable as it reuses
  the simple sysfs_upload interface to just cat(1) a blob to a sysfs
  file and pipe that to the device.

  Additionally there are a substantial number of cleanups and
  reorganizations to get ready for RCH error handling (RCH == Restricted
  CXL Host == current shipping hardware generation / pre CXL-2.0
  topologies) and type-2 (accelerator / vendor specific) devices.

  For vendor specific devices they implement a subset of what the
  generic type-3 (generic memory expander) driver expects. As a result
  the rework decouples optional infrastructure from the core driver
  context.

  For RCH topologies, where the specification working group did not want
  to confuse pre-CXL-aware operating systems, many of the standard
  registers are hidden which makes support standard bus features like
  AER (PCIe Advanced Error Reporting) difficult. The rework arranges for
  the driver to help the PCI-AER core. Bjorn is on board with this
  direction but a late regression disocvery means the completion of this
  functionality needs to cook a bit longer, so it is code
  reorganizations only for now.

  Summary:

   - Add infrastructure for supporting background commands along with
     support for device sanitization and firmware update

   - Introduce a CXL performance monitoring unit driver based on the
     common definition in the specification.

   - Land some preparatory cleanup and refactoring for the anticipated
     arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1
     topology) error handling.

   - Rework CPU cache management with respect to region configuration
     (device hotplug or other dynamic changes to memory interleaving)

   - Fix region reconfiguration vs CXL decoder ordering rules"

Pull networking changes from Jakub Kicinski:
 "WiFi 7 and sendpage changes are the biggest pieces of work for this
  release. The latter will definitely require fixes but I think that we
  got it to a reasonable point.

  Core:

   - Rework the sendpage & splice implementations

     Instead of feeding data into sockets page by page extend sendmsg
     handlers to support taking a reference on the data, controlled by a
     new flag called MSG_SPLICE_PAGES

     Rework the handling of unexpected-end-of-file to invoke an
     additional callback instead of trying to predict what the right
     combination of MORE/NOTLAST flags is

     Remove the MSG_SENDPAGE_NOTLAST flag completely

   - Implement SCM_PIDFD, a new type of CMSG type analogous to
     SCM_CREDENTIALS, but it contains pidfd instead of plain pid

   - Enable socket busy polling with CONFIG_RT

   - Improve reliability and efficiency of reporting for ref_tracker

   - Auto-generate a user space C library for various Netlink families

  Protocols:

   - Allow TCP to shrink the advertised window when necessary, prevent
     sk_rcvbuf auto-tuning from growing the window all the way up to
     tcp_rmem[2]

   - Use per-VMA locking for "page-flipping" TCP receive zerocopy

   - Prepare TCP for device-to-device data transfers, by making sure
     that payloads are always attached to skbs as page frags

   - Make the backoff time for the first N TCP SYN retransmissions
     linear. Exponential backoff is unnecessarily conservative

   - Create a new MPTCP getsockopt to retrieve all info
     (MPTCP_FULL_INFO)

   - Avoid waking up applications using TLS sockets until we have a full
     record

   - Allow using kernel memory for protocol ioctl callbacks, paving the
     way to issuing ioctls over io_uring

   - Add nolocalbypass option to VxLAN, forcing packets to be fully
     encapsulated even if they are destined for a local IP address

   - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
     in-kernel ECMP implementation (e.g. Open vSwitch) select the same
     link for all packets. Support L4 symmetric hashing in Open vSwitch

   - PPPoE: make number of hash bits configurable

   - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
     (ipconfig)

     self-explanatory):
      - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
        bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
        and bpf_dynptr_clone().
      - bpf_task_under_cgroup()

   - Factor Clause 73 auto-negotiation code out of the drivers, provide
     common helper routines

   - Add more fool-proof helpers for managing lifetime of MDIO devices
     associated with the PCS layer

   - Allow drivers to report advanced statistics related to Time Aware
     scheduler offload (taprio)

867eab655d Merge branch 'for-6.5/cxl-fwupd' into for-6.5/cxl
Add the first typical (non-sanitization) consumer of the new background
command infrastructure, firmware update. Given both firmware-update and
sanitization were developed in parallel from the common
background-command baseline, resolve some minor context conflicts.

9521875bbe cxl: add a firmware update mechanism using the sysfs firmware loader
The sysfs based firmware loader mechanism was created to easily allow
userspace to upload firmware images to FPGA cards. This also happens to
be pretty suitable to create a user-initiated but kernel-controlled
firmware update mechanism for CXL devices, using the CXL specified
mailbox commands.

Since firmware update commands can be long-running, and can be processed
in the background by the endpoint device, it is desirable to have the
ability to chunk the firmware transfer down to smaller pieces, so that
one operation does not monopolize the mailbox, locking out any other
long running background commands entirely - e.g. security commands like
'sanitize' or poison scanning operations.

The firmware loader mechanism allows a natural way to perform this
chunking, as after each mailbox command, that is restricted to the
maximum mailbox payload size, the cxl memdev driver relinquishes control
back to the fw_loader system and awaits the next chunk of data to
transfer. This opens opportunities for other background commands to
access the mailbox and send their own slices of background commands.

Add the necessary helpers and state tracking to be able to perform the
'Get FW Info', 'Transfer FW', and 'Activate FW' mailbox commands as
described in the CXL spec. Wire these up to the firmware loader
callbacks, and register with that system to create the memX/firmware/
sysfs ABI.

180ffd338c cxl/mem: Support Secure Erase
Implement support for the non-pmem exclusive secure erase, per
CXL specs. Create a write-only 'security/erase' sysfs file to
perform the requested operation.

As with the sanitation this requires the device being offline
and thus no active HPA-DPA decoding.

The expectation is that userspace can use it such as:

	cxl disable-memdev memX
	echo 1 > /sys/bus/cxl/devices/memX/security/erase
	cxl enable-memdev memX

48dcdbb16e cxl/mem: Wire up Sanitization support
Implement support for CXL 3.0 8.2.9.8.5.1 Sanitize. This is done by
adding a security/sanitize' memdev sysfs file to trigger the operation
and extend the status file to make it poll(2)-capable for completion.
Unlike all other background commands, this is the only operation that
is special and monopolizes the device for long periods of time.

In addition to the traditional pmem security requirements, all regions
must also be offline in order to perform the operation. This permits
avoiding explicit global CPU cache management, relying instead on the
implict cache management when a region transitions between
CXL_CONFIG_ACTIVE and CXL_CONFIG_COMMIT.

The expectation is that userspace can use it such as:

    cxl disable-memdev memX
    echo 1 > /sys/bus/cxl/devices/memX/security/sanitize
    cxl wait-sanitize memX
    cxl enable-memdev memX
