efa916af13 - Add DM infrastructure for IMA-based remote attestion. These changes
are the basis for deploying DM-based storage in a "cloud" that must
   validate configurations end-users run to maintain trust. These DM
   changes allow supported DM targets' configurations to be measured
   via IMA. But the policy and enforcement (of which configurations are
   valid) is managed by something outside the kernel (e.g. Keylime).
 
 - Fix DM crypt scalability regression on systems with many cpus due to
   percpu_counter spinlock contention in crypt_page_alloc().
 
 - Use in_hardirq() instead of deprecated in_irq() in DM crypt.
 
 - Add event counters to DM writecache to allow users to further assess
   how the writecache is performing.
 
 - Various code cleanup in DM writecache's main IO mapping function.

Pull idmapping documentation updates from Christian Brauner:
 "The bulk of the idmapped work this cycle was adding support for
  idmapped mounts to btrfs.

  While this required the addition of a (simple) new vfs helper all the
  work is going through David Sterba's btrfs tree. It was way simpler to
  do it this way rather then forcing David to coordinate between his
  btrfs and my tree. Plus I don't care who merges it as long as I feel I
  can trust the maintainer and the btrfs folks were really fast and
  helpful in reviewing this work.

  As always, associated with the btrfs port for idmapped mounts is a new
  fstests extension specifically concerned with btrfs ioctls (e.g.
  subvolume creation, deletion etc.) on idmapped mounts which can be
  found in the fstests repo as 5f8179ce8b00 ("btrfs: introduce btrfs
  specific idmapped mounts tests").

  Consequently, this cycle the idmapping pull is boring. It only
  contains documentation updates, specifically about how idmappings and
  idmapped mounts work"

Merge tag '5.15-rc-first-ksmbd-merge' of git://git.samba.org/ksmbd

Pull initial ksmbd implementation from Steve French:
 "Initial merge of kernel smb3 file server, ksmbd.

  The SMB family of protocols is the most widely deployed network
  filesystem protocol, the default on Windows and Macs (and even on many
  phones and tablets), with clients and servers on all major operating
  systems, but lacked a kernel server for Linux. For many cases the
  current userspace server choices were suboptimal either due to memory
  footprint, performance or difficulty integrating well with advanced
  Linux features.

  ksmbd is a new kernel module which implements the server-side of the
  SMB3 protocol. The target is to provide optimized performance, GPLv2
  SMB server, and better lease handling (distributed caching). The
  bigger goal is to add new features more rapidly (e.g. RDMA aka
  "smbdirect", and recent encryption and signing improvements to the
  protocol) which are easier to develop on a smaller, more tightly
  optimized kernel server than for example in Samba.

  The Samba project is much broader in scope (tools, security services,
  LDAP, Active Directory Domain Controller, and a cross platform file
  server for a wider variety of purposes) but the user space file server
  portion of Samba has proved hard to optimize for some Linux workloads,
  including for smaller devices.

  This is not meant to replace Samba, but rather be an extension to
  allow better optimizing for Linux, and will continue to integrate well
  with Samba user space tools and libraries where appropriate. Working
  with the Samba team we have already made sure that the configuration
  files and xattrs are in a compatible format between the kernel and
  user space server.

  Various types of functional and regression tests are regularly run
  against it. One example is the automated 'buildbot' regression tests
  which use the Linux client to test against ksmbd, e.g.

     http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com/#/builders/8/builds/56

  but other test suites, including Samba's smbtorture functional test
  suite are also used regularly"

8596e589b7 Updates for timekeeping, timers and related drivers:
Core code:
 
   - Cure a couple of incorrectness issues in the posix CPU timer code to
     prevent that the tick dependency for NOHZ full is kept alive for no
     reason.
 
   - Avoid expensive double reprogramming of the clockevent device in
     hrtimer_start_range_ns().
 
   - Avoid pointless SMP function calls when the clock was set to avoid
     disturbing CPUs which do not have any affected timers queued.
 
   - Make the clocksource watchdog test work correctly when CONFIG_HZ is
     less than 100.
 
 Drivers:
 
   - Prefer the ARM architected timer over the Exynos timer which is way
     more expensive to access.
 
   - Add device tree bindings for new Ingenic SoCs
 
   - The usual improvements and cleanups all over the place

0a096f240a A reworked version of the opt-in L1D flush mechanism:
A stop gap for potential future speculation related hardware
   vulnerabilities and a mechanism for truly security paranoid
   applications.
 
   It allows a task to request that the L1D cache is flushed when the kernel
   switches to a different mm. This can be requested via prctl().
 
   Changes vs. the previous versions:
 
     - Get rid of the software flush fallback
 
     - Make the handling consistent with other mitigations
 
     - Kill the task when it ends up on a SMT enabled core which defeats the
       purpose of L1D flushing obviously

e5e726f7bb Updates for locking and atomics:
The regular pile:
 
   - A few improvements to the mutex code
 
   - Documentation updates for atomics to clarify the difference between
     cmpxchg() and try_cmpxchg() and to explain the forward progress
     expectations.
 
   - Simplification of the atomics fallback generator
 
   - The addition of arch_atomic_long*() variants and generic arch_*()
     bitops based on them.
 
   - Add the missing might_sleep() invocations to the down*() operations of
     semaphores.
 
 The PREEMPT_RT locking core:
 
   - Scheduler updates to support the state preserving mechanism for
     'sleeping' spin- and rwlocks on RT. This mechanism is carefully
     preserving the state of the task when blocking on a 'sleeping' spin- or
     rwlock and takes regular wake-ups targeted at the same task into
     account. The preserved or updated (via a regular wakeup) state is
     restored when the lock has been acquired.
 
   - Restructuring of the rtmutex code so it can be utilized and extended
     for the RT specific lock variants.
 
   - Restructuring of the ww_mutex code to allow sharing of the ww_mutex
     specific functionality for rtmutex based ww_mutexes.
 
   - Header file disentangling to allow substitution of the regular lock
     implementations with the PREEMPT_RT variants without creating an
     unmaintainable #ifdef mess.
 
   - Shared base code for the PREEMPT_RT specific rw_semaphore and rwlock
     implementations. Contrary to the regular rw_semaphores and rwlocks the
     PREEMPT_RT implementation is writer unfair because it is infeasible to
     do priority inheritance on multiple readers. Experience over the years
     has shown that real-time workloads are not the typical workloads which
     are sensitive to writer starvation. The alternative solution would be
     to allow only a single reader which has been tried and discarded as it
     is a major bottleneck especially for mmap_sem. Aside of that many of
     the writer starvation critical usage sites have been converted to a
     writer side mutex/spinlock and RCU read side protections in the past
     decade so that the issue is less prominent than it used to be.
 
   - The actual rtmutex based lock substitutions for PREEMPT_RT enabled
     kernels which affect mutex, ww_mutex, rw_semaphore, spinlock_t and
     rwlock_t. The spin/rw_lock*() functions disable migration across the
     critical section to preserve the existing semantics vs. per CPU
     variables.
 
   - Rework of the futex REQUEUE_PI mechanism to handle the case of early
     wake-ups which interleave with a re-queue operation to prevent the
     situation that a task would be blocked on both the rtmutex associated
     to the outer futex and the rtmutex based hash bucket spinlock.
 
     While this situation cannot happen on !RT enabled kernels the changes
     make the underlying concurrency problems easier to understand in
     general. As a result the difference between !RT and RT kernels is
     reduced to the handling of waiting for the critical section. !RT
     kernels simply spin-wait as before and RT kernels utilize rcu_wait().
 
   - The substitution of local_lock for PREEMPT_RT with a spinlock which
     protects the critical section while staying preemptible. The CPU
     locality is established by disabling migration.
 
   The underlying concepts of this code have been in use in PREEMPT_RT for
   way more than a decade. The code has been refactored several times over
   the years and this final incarnation has been optimized once again to be
   as non-intrusive as possible, i.e. the RT specific parts are mostly
   isolated.
 
   It has been extensively tested in the 5.14-rt patch series and it has
   been verified that !RT kernels are not affected by these changes.

Netfilter updates for net-next

The following patchset contains Netfilter updates for net-next:

1) Clean up and consolidate ct ecache infrastructure by merging ct and
   expect notifiers, from Florian Westphal.

2) Missing counters and timestamp in nfnetlink_queue and _log conntrack
   information.

3) Missing error check for xt_register_template() in iptables mangle,
   as a incremental fix for the previous pull request, also from
   Florian Westphal.

4) Add netfilter hooks for the SRv6 lightweigh tunnel driver, from
   Ryoga Sato. The hooks are enabled via nf_hooks_lwtunnel sysctl
   to make sure existing netfilter rulesets do not break. There is
   a static key to disable the hooks by default.

   The pktgen_bench_xmit_mode_netif_receive.sh shows no noticeable
   impact in the seg6_input path for non-netfilter users: similar
   numbers with and without this patch.

0e35f63f7f hwmon: add driver for Aquacomputer D5 Next
This driver exposes hardware sensors of the Aquacomputer D5 Next
watercooling pump, which communicates through a proprietary USB HID
protocol.

Available sensors are pump and fan speed, power, voltage and current, as
well as coolant temperature. Also available through debugfs are the serial
number, firmware version and power-on count.

Attaching a fan is optional and allows it to be controlled using
temperature curves directly from the pump. If it's not connected,
the fan-related sensors will report zeroes.

The pump can be configured either through software or via its physical
interface. Configuring the pump through this driver is not implemented,
as it seems to require sending it a complete configuration. That
includes addressable RGB LEDs, for which there is no standard sysfs
interface. Thus, that task is better suited for userspace tools.

This driver has been tested on x86_64, both in-kernel and as a module.

246b184fff pktgen: document the latest pktgen usage options
Currently, the pktgen.rst documentation doesn't cover the latest pktgen
sample usage options such as count and IPv6, and so on. Also, this
documentation includes the old sample scripts which are no longer use
because it was removed by the commit a4b6ade8359f ("samples/pktgen :
remove remaining old pktgen sample scripts")

Thus, this commit documents pktgen sample usage using the latest options
and removes old sample scripts, and fixes a minor typo.

029ee6b143 ethtool: add two coalesce attributes for CQE mode
Currently, there are many drivers who support CQE mode configuration,
some configure it as a fixed when initialized, some provide an
interface to change it by ethtool private flags. In order to make it
more generic, add two new 'ETHTOOL_A_COALESCE_USE_CQE_TX' and
'ETHTOOL_A_COALESCE_USE_CQE_RX' coalesce attributes, then these
parameters can be accessed by ethtool netlink coalesce uAPI.

Also add an new structure kernel_ethtool_coalesce, then the
new parameter can be added into this struct.
