Here's some small fixes for 5.10-rc2 and a big driver removal.
The fixes are for some reported issues in the interconnect and coresight
drivers, nothing major.
The "big" driver removal is the MIC drivers have been asked to be
removed as the hardware never shipped and Intel no longer wants to
maintain something that no one can use. This is welcomed by many as the
DMA usage of these drivers was "interesting" and the security people
were starting to question some issues that were starting to be found in
the codebase.
Note, one of the subsystems for this driver, the "VOP" code, will
probably come back in future kernel versions as it was looking to
potentially solve some PCIe virtualization issues that a number of other
vendors were wanting to solve. But as-is, this codebase didn't work for
anyone else so no actual functionality is being removed.
All of these have been in linux-next with no reported issues.

Fixes all over the place. A new UAPI is borderline: can also be
considered a new feature but also seems to be the only way we could come
up with to fix addressing for userspace - and it seems important to
switch to it now before userspace making assumptions about addressing
ability of devices is set in stone.

This patch removes the MIC drivers from the kernel tree
since the corresponding devices have been discontinued.
Removing the dma and char-misc changes in one patch and
merging via the char-misc tree is best to avoid any
potential build breakage.

- r8169: fix operation under forced interrupt threading, make the

This patch introduces a new ioctl for vhost-vdpa device that can
report the iova range by the device.
For device that implements get_iova_range() method, we fetch it from
the vDPA device. If device doesn't implement get_iova_range() but
depends on platform IOMMU, we will query via DOMAIN_ATTR_GEOMETRY,
otherwise [0, ULLONG_MAX] is assumed.
For safety, this patch also rules out the map request which is not in
the valid range.

Based on the discussion in [0], update the bpf_redirect_neigh() helper to
accept an optional parameter specifying the nexthop information. This makes
it possible to combine bpf_fib_lookup() and bpf_redirect_neigh() without
incurring a duplicate FIB lookup - since the FIB lookup helper will return
the nexthop information even if no neighbour is present, this can simply
be passed on to bpf_redirect_neigh() if bpf_fib_lookup() returns
BPF_FIB_LKUP_RET_NO_NEIGH. Thus fix & extend it before helper API is frozen.

KVM unconditionally provides PV features to the guest, regardless of the
configured CPUID. An unwitting guest that doesn't check
KVM_CPUID_FEATURES before use could access paravirt features that
userspace did not intend to provide. Fix this by checking the guest's
CPUID before performing any paravirtual operations.
Introduce a capability, KVM_CAP_ENFORCE_PV_FEATURE_CPUID, to gate the
aforementioned enforcement. Migrating a VM from a host w/o this patch to
a host with this patch could silently change the ABI exposed to the
guest, warranting that we default to the old behavior and opt-in for
the new one.

- A series from Nick adding ARCH_WANT_IRQS_OFF_ACTIVATE_MM & selecting
it for powerpc, as well as a related fix for sparc.
- Remove support for PowerPC 601.
- Some fixes for watchpoints & addition of a new ptrace flag for
detecting ISA v3.1 (Power10) watchpoint features.
- A fix for kernels using 4K pages and the hash MMU on bare metal
Power9 systems with > 16TB of RAM, or RAM on the 2nd node.
- A basic idle driver for shallow stop states on Power10.
- Tweaks to our sched domains code to better inform the scheduler about
the hardware topology on Power9/10, where two SMT4 cores can be
presented by firmware as an SMT8 core.
- A series doing further reworks & cleanups of our EEH code.
- Addition of a filter for RTAS (firmware) calls done via sys_rtas(),
to prevent root from overwriting kernel memory.
- Other smaller features, fixes & cleanups.

Previously we computed L1.2 parameters in the enumeration path, saved them
in struct pcie_link_state.l1ss, and programmed them into the devices
whenever we enabled or disabled L1.2 on the link. But these parameters are
constant and don't need to be updated when enabling/disabling L1.2.
Compute and program the L1.2 parameters once during enumeration and remove
the struct pcie_link_state.l1ss member. No functional change intended.

Add redirect_neigh() BPF packet redirect helper, allowing to limit stack
traversal in common container configs and improving TCP back-pressure.
Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain.
Expand netlink policy support and improve policy export to user space.
(Ge)netlink core performs request validation according to declared
policies. Expand the expressiveness of those policies (min/max length
and bitmasks). Allow dumping policies for particular commands.
This is used for feature discovery by user space (instead of kernel
version parsing or trial and error).
Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge.
Allow more than 255 IPv4 multicast interfaces.
Add support for Type of Service (ToS) reflection in SYN/SYN-ACK
packets of TCPv6.
In Multi-patch TCP (MPTCP) support concurrent transmission of data
on multiple subflows in a load balancing scenario. Enhance advertising
addresses via the RM_ADDR/ADD_ADDR options.
Support SMC-Dv2 version of SMC, which enables multi-subnet deployments.
Allow more calls to same peer in RxRPC.
Support two new Controller Area Network (CAN) protocols -
CAN-FD and ISO 15765-2:2016.
Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit
kernel problem.
Add TC actions for implementing MPLS L2 VPNs.
Improve nexthop code - e.g. handle various corner cases when nexthop
objects are removed from groups better, skip unnecessary notifications
and make it easier to offload nexthops into HW by converting
to a blocking notifier.
Support adding and consuming TCP header options by BPF programs,
opening the doors for easy experimental and deployment-specific
TCP option use.
Reorganize TCP congestion control (CC) initialization to simplify life
of TCP CC implemented in BPF.
Add support for shipping BPF programs with the kernel and loading them
early on boot via the User Mode Driver mechanism, hence reusing all the
user space infra we have.
Support sleepable BPF programs, initially targeting LSM and tracing.
Add bpf_d_path() helper for returning full path for given 'struct path'.
Make bpf_tail_call compatible with bpf-to-bpf calls.
Allow BPF programs to call map_update_elem on sockmaps.
Add BPF Type Format (BTF) support for type and enum discovery, as
well as support for using BTF within the kernel itself (current use
is for pretty printing structures).
Support listing and getting information about bpf_links via the bpf
syscall.
Enhance kernel interfaces around NIC firmware update. Allow specifying
overwrite mask to control if settings etc. are reset during update;
report expected max time operation may take to users; support firmware
activation without machine reboot incl. limits of how much impact
reset may have (e.g. dropping link or not).
Extend ethtool configuration interface to report IEEE-standard
counters, to limit the need for per-vendor logic in user space.
Adopt or extend devlink use for debug, monitoring, fw update
in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw,
mv88e6xxx, dpaa2-eth).
In mlxsw expose critical and emergency SFP module temperature alarms.
Refactor port buffer handling to make the defaults more suitable and
support setting these values explicitly via the DCBNL interface.
Add XDP support for Intel's igb driver.
Support offloading TC flower classification and filtering rules to
mscc_ocelot switches.
Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
fixed interval period pulse generator and one-step timestamping in
dpaa-eth.
Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
offload.
Add Lynx PHY/PCS MDIO module, and convert various drivers which have
this HW to use it. Convert mvpp2 to split PCS.
Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
7-port Mediatek MT7531 IP.
Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
and wcn3680 support in wcn36xx.
Improve performance for packets which don't require much offloads
on recent Mellanox NICs by 20% by making multiple packets share
a descriptor entry.
Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto
subtree to drivers/net. Move MDIO drivers out of the phy directory.
Clean up a lot of W=1 warnings, reportedly the actively developed
subsections of networking drivers should now build W=1 warning free.
Make sure drivers don't use in_interrupt() to dynamically adapt their
code. Convert tasklets to use new tasklet_setup API (sadly this
conversion is not yet complete).

nftables payload statements are used to mangle SCTP headers, but they can
only replace the Internet Checksum. As a consequence, nftables rules that
mangle sport/dport/vtag in SCTP headers potentially generate packets that
are discarded by the receiver, unless the CRC-32C is "offloaded" (e.g the
rule mangles a skb having 'ip_summed' equal to 'CHECKSUM_PARTIAL'.
Fix this extending uAPI definitions and L4 checksum update function, in a
way that userspace programs (e.g. nft) can instruct the kernel to compute
CRC-32C in SCTP headers. Also ensure that LIBCRC32C is built if NF_TABLES
is 'y' or 'm' in the kernel build configuration.

The biggest change is retrying the initial information fetch from the

and one group was having trouble with the management controller not
being ready when the OS started up. So a retry was added.

Pull pidfd updates from Christian Brauner:
"This introduces a new extension to the pidfd_open() syscall. Users can
now raise the new PIDFD_NONBLOCK flag to support non-blocking pidfd
file descriptors. This has been requested for uses in async process
management libraries such as async-pidfd in Rust.
Ever since the introduction of pidfds and more advanced async io
various programming languages such as Rust have grown support for
async event libraries. These libraries are created to help build
epoll-based event loops around file descriptors. A common pattern is
to automatically make all file descriptors they manage to O_NONBLOCK.
For such libraries the EAGAIN error code is treated specially. When a
function is called that returns EAGAIN the function isn't called again
until the event loop indicates the the file descriptor is ready.
Supporting EAGAIN when waiting on pidfds makes such libraries just
work with little effort.
This introduces a new flag PIDFD_NONBLOCK that is equivalent to
O_NONBLOCK. This follows the same patterns we have for other (anon
inode) file descriptors such as EFD_NONBLOCK, IN_NONBLOCK,
SFD_NONBLOCK, TFD_NONBLOCK and the same for close-on-exec flags.
Passing a non-blocking pidfd to waitid() currently has no effect, i.e.
is not supported. There are users which would like to use waitid() on
pidfds that are O_NONBLOCK and mix it with pidfds that are blocking
and both pass them to waitid().
The expected behavior is to have waitid() return -EAGAIN for
non-blocking pidfds and to block for blocking pidfds without needing
to perform any additional checks for flags set on the pidfd before
passing it to waitid(). Non-blocking pidfds will return EAGAIN from
waitid() when no child process is ready yet. Returning -EAGAIN for
non-blocking pidfds makes it easier for event loops that handle EAGAIN
specially.
It also makes the API more consistent and uniform. In essence,
waitid() is treated like a read on a non-blocking pidfd or a recvmsg()
on a non-blocking socket.
With the addition of support for non-blocking pidfds we support the
same functionality that sockets do. For sockets() recvmsg() supports
MSG_DONTWAIT for pidfds waitid() supports WNOHANG. Both flags are
per-call options. In contrast non-blocking pidfds and non-blocking
sockets are a setting on an open file description affecting all
threads in the calling process as well as other processes that hold
file descriptors referring to the same open file description. Both
behaviors, per call and per open file description, have genuine
use-cases.
The interaction with the WNOHANG flag is documented as follows:
- If a non-blocking pidfd is passed and WNOHANG is not raised we
simply raise the WNOHANG flag internally. When do_wait() returns
indicating that there are eligible child processes but none have
exited yet we set EAGAIN. If no child process exists we continue
returning ECHILD.
- If a non-blocking pidfd is passed and WNOHANG is raised waitid()
will continue returning 0, i.e. it will not set EAGAIN. This ensure
backwards compatibility with applications passing WNOHANG
explicitly with pidfds"

tests: remove O_NONBLOCK before waiting for WSTOPPED
tests: add waitid() tests for non-blocking pidfds

Core changes:
- The big core change is the updated (v2) userspace character
device API. This corrects badly designed 64-bit alignment around
the line events. We also add the debounce request feature.
This echoes the often quotes passage from Frederick Brooks
"The mythical man-month" to always throw one away, which we
have seen before in things such as V4L2. So we put in a new
one and deprecate and obsolete the old one.
- All example tools in tools/gpio/* are migrated to the new API
to set a good example. The libgpiod userspace library has been
augmented to use this new API pretty much from day 1.
- Some misc API hardening by using strn* function calls has been
added as well.
- Use the simpler IDA interface for GPIO chip instance enumeration.
- Add device core function for counting string arrays in
device properties.
- Provide a generic library function kfree_strarray() that can
be used throughout the kernel.
Driver enhancements:
- The DesignWare dwapb-gpio driver has been enhanced and now
uses the IRQ handling in the gpiolib core.
- The mockup and aggregator drivers have seen some substantial
code clean-up and now use more of the core kernel
inftrastructure.
- Misc cleanups using dev_err_probe().
- The MXC drivers (Freescale/NXP) can now be built modularized,
which makes modularized GKI Android kernels happy.

We have some interesting cooperative work for ARM and Intel alike,
making the GPIO subsystem more and more suitable for industrial
systems and the like, in addition to the in-kernel users.
We touch driver core (device properties) and lib/* by adding one
simple string array free function, these are authored by Andy
Shevchenko who is a well known and recognized core helpers maintainers
so this should be fine.
We also see some Android GKI-related modularization in the MXC
drivers.

Pull btrfs updates from David Sterba:
"Mostly core updates with a few user visible bits and fixes.
Hilights:
- fsync performance improvements
- less contention of log mutex (throughput +4%, latency -14%,
dbench with 32 clients)
- skip unnecessary commits for link and rename (throughput +6%,
latency -30%, rename latency -75%, dbench with 16 clients)
- make fast fsync wait only for writeback (throughput +10..40%,
runtime -1..-20%, dbench with 1 to 64 clients on various
file/block sizes)
- direct io is now implemented using the iomap infrastructure, that's
the main part, we still have a workaround that requires an iomap
API update, coming in 5.10
- new sysfs exports:
- information about the exclusive filesystem operation status
(balance, device add/remove/replace, ...)
- supported send stream version
Core:
- use ticket space reservations for data, fair policy using the same
infrastructure as metadata
- preparatory work to switch locking from our custom tree locks to
standard rwsem, now the locking context is propagated to all
callers, actual switch is expected to happen in the next dev cycle
- seed device structures are now using list API
- extent tracepoints print proper tree id
- unified range checks for extent buffer helpers
- send: avoid using temporary buffer for copying data
- remove unnecessary RCU protection from space infos
- remove unused readpage callback for metadata, enabling several
cleanups
- replace indirect function calls for end io hooks and remove
extent_io_ops completely
Fixes:
- more lockdep warning fixes
- fix qgroup reservation for delayed inode and an occasional
reservation leak for preallocated files
- fix device replace of a seed device
- fix metadata reservation for fallocate that leads to transaction
aborts
- reschedule if necessary when logging directory items or when
cloning lots of extents
- tree-checker: fix false alert caused by legacy btrfs root item
- send: fix rename/link conflicts for orphanized inodes
- properly initialize device stats for seed devices
- skip devices without magic signature when mounting
Other:
- error handling improvements, BUG_ONs replaced by proper handling,
fuzz fixes
- various function parameter cleanups
- various W=1 cleanups
- error/info messages improved
Mishaps:
- commit 62cf539120 ("btrfs: move btrfs_rm_dev_replace_free_srcdev
outside of all locks") is a rebase leftover after the patch got
merged to 5.9-rc8 as a466c85edc ("btrfs: move
btrfs_rm_dev_replace_free_srcdev outside of all locks"), the
remaining part is trivial and the patch is in the middle of the
series so I'm keeping it there instead of rebasing"

This release, we rework the implementation of creating new encrypted
files in order to fix some deadlocks and prepare for adding fscrypt
support to CephFS, which Jeff Layton is working on.
We also export a symbol in preparation for the above-mentioned CephFS
support and also for ext4/f2fs encrypt+casefold support.
Finally, there are a few other small cleanups.
As usual, all these patches have been in linux-next with no reported
issues, and I've tested them with xfstests.

Pull arm64 updates from Will Deacon:
"There's quite a lot of code here, but much of it is due to the
addition of a new PMU driver as well as some arm64-specific selftests
which is an area where we've traditionally been lagging a bit.
In terms of exciting features, this includes support for the Memory
Tagging Extension which narrowly missed 5.9, hopefully allowing
userspace to run with use-after-free detection in production on CPUs
that support it. Work is ongoing to integrate the feature with KASAN
for 5.11.
Another change that I'm excited about (assuming they get the hardware
right) is preparing the ASID allocator for sharing the CPU page-table
with the SMMU. Those changes will also come in via Joerg with the
IOMMU pull.
We do stray outside of our usual directories in a few places, mostly
due to core changes required by MTE. Although much of this has been
Acked, there were a couple of places where we unfortunately didn't get
any review feedback.
Other than that, we ran into a handful of minor conflicts in -next,
but nothing that should post any issues.
Summary:
- Userspace support for the Memory Tagging Extension introduced by
Armv8.5. Kernel support (via KASAN) is likely to follow in 5.11.
- Selftests for MTE, Pointer Authentication and FPSIMD/SVE context

This patch adds the NF_INET_INGRESS pseudohook for the NFPROTO_INET
family. This is a mapping this new hook to the existing NFPROTO_NETDEV
and NF_NETDEV_INGRESS hook. The hook does not guarantee that packets are
inet only, users must filter out non-ip traffic explicitly.
This infrastructure makes it easier to support this new hook in nf_tables.
