Pull IIO and staging driver updates from Greg KH:
"Here is the big set of staging and IIO driver updates for 5.15-rc1.
Also included in here are the counter driver subsystem updates as the
IIO drivers needed them.
Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
driver and replaced it with a newer version of the driver that had
been maintained out-of-tree by Larry with the end goal of actually
being able to get this driver out of staging eventually. Despite that
driver being "newer" the line count of this pull request is going up.
Some drivers moved out of staging as well, which is always nice to
see, that is why there are additions to the mfc and misc driver
subsystems. All of these were acked by the various subsystem
maintainers involved.
But by far, as normal, it's coding style cleanups all over the
drivers/staging/ tree in here.
Full details of these changes are in the shortlog.
All of these have been in linux-next for a while with no reported
problems"
[ Note: the r8188eu merge clashed with commit 89939e890605 ("staging:
rtlwifi: use siocdevprivate") from the networking tree. When resolving
the issue, I noted that the whole r8188eu rtw_android code is dead
since commit ae7471cae00a ("staging: r8188eu: remove rtw_ioctl
function").
End result: the merge resolution was to throw all of that away,
rather than do the mindless fixup to code that isn't actually
reachable - Linus ]

Pull device mapper updates from Mike Snitzer:
- 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"

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

- Make the handling consistent with other mitigations
- Kill the task when it ends up on a SMT enabled core which defeats

Pull locking and atomics updates from Thomas Gleixner:
"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.
This is a sample of the perf report output:
11.67% kpktgend_0 [ipv6] [k] ipv6_get_saddr_eval
7.89% kpktgend_0 [ipv6] [k] __ipv6_addr_label

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.

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.

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.
