Pull networking updates from Jakub Kicinski:
"The sprinkling of SPI drivers is because we added a new one and Mark
sent us a SPI driver interface conversion pull request.
Core
----
- Introduce XDP multi-buffer support, allowing the use of XDP with
jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
- Speed up netns dismantling (5x) and lower the memory cost a little.
Remove unnecessary per-netns sockets. Scope some lists to a netns.
Cut down RCU syncing. Use batch methods. Allow netdev registration
to complete out of order.
- Support distinguishing timestamp types (ingress vs egress) and
maintaining them across packet scrubbing points (e.g. redirect).
- Continue the work of annotating packet drop reasons throughout the
stack.
- Switch netdev error counters from an atomic to dynamically
allocated per-CPU counters.
- Rework a few preempt_disable(), local_irq_save() and busy waiting
sections problematic on PREEMPT_RT.
- Extend the ref_tracker to allow catching use-after-free bugs.
BPF
---
- Introduce "packing allocator" for BPF JIT images. JITed code is
marked read only, and used to be allocated at page granularity.
Custom allocator allows for more efficient memory use, lower iTLB
pressure and prevents identity mapping huge pages from getting
split.
- Make use of BTF type annotations (e.g. __user, __percpu) to enforce
the correct probe read access method, add appropriate helpers.
- Convert the BPF preload to use light skeleton and drop the
user-mode-driver dependency.
- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
its use as a packet generator.
- Allow local storage memory to be allocated with GFP_KERNEL if
called from a hook allowed to sleep.
- Introduce fprobe (multi kprobe) to speed up mass attachment (arch
bits to come later).
- Add unstable conntrack lookup helpers for BPF by using the BPF
kfunc infra.
- Allow cgroup BPF progs to return custom errors to user space.
- Add support for AF_UNIX iterator batching.
- Allow iterator programs to use sleepable helpers.
- Support JIT of add, and, or, xor and xchg atomic ops on arm64.
- Add BTFGen support to bpftool which allows to use CO-RE in kernels
without BTF info.
- Large number of libbpf API improvements, cleanups and deprecations.
Protocols
---------
- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
- Adjust TSO packet sizes based on min_rtt, allowing very low latency
links (data centers) to always send full-sized TSO super-frames.
- Make IPv6 flow label changes (AKA hash rethink) more configurable,
via sysctl and setsockopt. Distinguish between server and client
behavior.
- VxLAN support to "collect metadata" devices to terminate only
configured VNIs. This is similar to VLAN filtering in the bridge.
- Support inserting IPv6 IOAM information to a fraction of frames.
- Add protocol attribute to IP addresses to allow identifying where
given address comes from (kernel-generated, DHCP etc.)
- Support setting socket and IPv6 options via cmsg on ping6 sockets.
- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
Define dscp_t and stop taking ECN bits into account in fib-rules.
- Add support for locked bridge ports (for 802.1X).
- tun: support NAPI for packets received from batched XDP buffs,
doubling the performance in some scenarios.
- IPv6 extension header handling in Open vSwitch.
- Support IPv6 control message load balancing in bonding, prevent
neighbor solicitation and advertisement from using the wrong port.
Support NS/NA monitor selection similar to existing ARP monitor.
- SMC
- improve performance with TCP_CORK and sendfile()
- support auto-corking
- support TCP_NODELAY
- MCTP (Management Component Transport Protocol)
- add user space tag control interface
- I2C binding driver (as specified by DMTF DSP0237)
- Multi-BSSID beacon handling in AP mode for WiFi.
- Bluetooth:
- handle MSFT Monitor Device Event
- add MGMT Adv Monitor Device Found/Lost events
- Multi-Path TCP:
- add support for the SO_SNDTIMEO socket option
- lots of selftest cleanups and improvements
- Increase the max PDU size in CAN ISOTP to 64 kB.
Driver API
----------
- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.
- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.
- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.
- Add header/data split indication to guide user space enabling of
TCP zero-copy Rx.
- Allow configuring completion queue event size.
- Refactor page_pool to enable fragmenting after allocation.
- Add allocation and page reuse statistics to page_pool.
- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.
- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

concurrency-managed work queue.
- Allowing yielding when zapping TDP MMU roots in response to the
root's last reference being put.

paging structure now holds RCU as a proxy for all vCPUs running
in the guest, i.e. to prolongs the grace period on their behalf.
It then kicks the the vCPUs out of guest mode before doing
rcu_read_unlock().

Pull tasklist_lock optimizations from Eric Biederman:
"prlimit and getpriority tasklist_lock optimizations
The tasklist_lock popped up as a scalability bottleneck on some
testing workloads. The readlocks in do_prlimit and set/getpriority are
not necessary in all cases.
Based on a cycles profile, it looked like ~87% of the time was spent
in the kernel, ~42% of which was just trying to get *some* spinlock
(queued_spin_lock_slowpath, not necessarily the tasklist_lock).
The big offenders (with rough percentages in cycles of the overall
trace):
- do_wait 11%
- setpriority 8% (done previously in commit 7f8ca0edfe07)
- kill 8%
- do_exit 5%
- clone 3%
- prlimit64 2% (this patchset)
- getrlimit 1% (this patchset)
I can't easily test this patchset on the original workload for various
reasons. Instead, I used the microbenchmark below to at least verify
there was some improvement. This patchset had a 28% speedup (12% from
baseline to set/getprio, then another 14% for prlimit).
This series used to do the setpriority case, but an almost identical
change was merged as commit 7f8ca0edfe07 ("kernel/sys.c: only take
tasklist_lock for get/setpriority(PRIO_PGRP)") so that has been
dropped from here.
One interesting thing is that my libc's getrlimit() was calling
prlimit64, so hoisting the read_lock(tasklist_lock) into sys_prlimit64
had no effect - it essentially optimized the older syscalls only. I
didn't do that in this patchset, but figured I'd mention it since it
was an option from the previous patch's discussion"

Pull ARM SoC updates from Arnd Bergmann:
"SoC specific code is generally used for older platforms that don't
(yet) use device tree to do the same things.
- Support is added for i.MXRT10xx, a Cortex-M7 based microcontroller
from NXP. At the moment this is still incomplete as other portions
are merged through different trees.
- Long abandoned support for running NOMMU ARMv4 or ARMv5 platforms
gets removed, now the Arm NOMMU platforms are limited to the
Cortex-M family of microcontrollers
- Two old PXA boards get removed, along with corresponding driver
bits.
- Continued cleanup of the Intel IXP4xx platforms, removing some
remnants of the old board files.
- Minor Cleanups and fixes for Orion, PXA, MMP, Mstar, Samsung
- CPU idle support for AT91
- A system controller driver for Polarfire"

Pull asm-generic updates from Arnd Bergmann:
"There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good.
This was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly tricky
and error-prone code. There is a small merge conflict against a
parisc cleanup, the solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel.
The hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks"

Pull ARM updates from Russell King:
"Updates for IRQ stacks and virtually mapped stack support, and ftrace:
- Support for IRQ and vmap'ed stacks
This covers all the work related to implementing IRQ stacks and
vmap'ed stacks for all 32-bit ARM systems that are currently
supported by the Linux kernel, including RiscPC and Footbridge. It
has been submitted for review in four different waves:
- IRQ stacks support for v7 SMP systems [0]
- vmap'ed stacks support for v7 SMP systems[1]
- extending support for both IRQ stacks and vmap'ed stacks for all
remaining configurations, including v6/v7 SMP multiplatform
kernels and uniprocessor configurations including v7-M [2]
- fixes and updates in [3]
- ftrace fixes and cleanups
Make all flavors of ftrace available on all builds, regardless of
ISA choice, unwinder choice or compiler [4]:
- use ADD not POP where possible
- fix a couple of Thumb2 related issues
- enable HAVE_FUNCTION_GRAPH_FP_TEST for robustness
- enable the graph tracer with the EABI unwinder
- avoid clobbering frame pointer registers to make Clang happy
- Fixes for the above"

Pull tracing updates from Steven Rostedt:
- New user_events interface. User space can register an event with the
kernel describing the format of the event. Then it will receive a
byte in a page mapping that it can check against. A privileged task
can then enable that event like any other event, which will change
the mapped byte to true, telling the user space application to start
writing the event to the tracing buffer.
- Add new "ftrace_boot_snapshot" kernel command line parameter. When
set, the tracing buffer will be saved in the snapshot buffer at boot
up when the kernel hands things over to user space. This will keep
the traces that happened at boot up available even if user space boot
up has tracing as well.
- Have TRACE_EVENT_ENUM() also update trace event field type
descriptions. Thus if a static array defines its size with an enum,
the user space trace event parsers can still know how to parse that
array.
- Add new TRACE_CUSTOM_EVENT() macro. This acts the same as the
TRACE_EVENT() macro, but will attach to an existing tracepoint. This
will make one tracepoint be able to trace different content and not
be stuck at only what the original TRACE_EVENT() macro exports.
- Fixes to tracing error logging.
- Better saving of cmdlines to PIDs when tracing (use the wakeup events
for mapping).

cpsw_ethtool_begin directly returns the result of pm_runtime_get_sync
when successful.
pm_runtime_get_sync returns -error code on failure and 0 on successful
resume but also 1 when the device is already active. So the common case
for cpsw_ethtool_begin is to return 1. That leads to inconsistent calls
to pm_runtime_put in the call-chain so that pm_runtime_put is called
one too many times and as result leaving the cpsw dev behind suspended.
The suspended cpsw dev leads to an access violation later on by
different parts of the cpsw driver.
Fix this by calling the return-friendly pm_runtime_resume_and_get
function.

ice_send_event_to_aux() eventually descends to mutex_lock()
(-> might_sched()), so it must not be called under non-task
context. However, at least two fixes have happened already for the
bug splats occurred due to this function being called from atomic
context.
To make the emergency landings softer, bail out early when executed
in non-task context emitting a warn splat only once. This way we
trade some events being potentially lost for system stability and
avoid any related hangs and crashes.

As Andrew correctly mentioned previously[0], the following call
ladder happens:
ice_misc_intr() <- hardirq
ice_send_event_to_aux()
device_lock()
mutex_lock()
might_sleep()
might_resched() <- oops
Add a new PF state bit which indicates that an aux critical error
occurred and serve it in ice_service_task() in process context.
The new ice_pf::oicr_err_reg is read-write in both hardirq and
process contexts, but only 3 bits of non-critical data probably
aren't worth explicit synchronizing (and they're even in the same
byte [31:24]).

All packets on ingress (except for jumbo) are terminated with a 4-bytes
CRC checksum. It's the responsability of the driver to strip those 4
bytes. Unfortunately a change dating back to March 2017 re-shuffled some
code and made the CRC stripping code effectively dead.
This change re-orders that part a bit such that the datalen is
immediately altered if needed.

The Kconfig symbols required for the Allwinner F1C100 (MACH_SUNIV) are
currently not selected by any defconfig. sunxi_defconfig only covers the
v7 SoCs, but the F1C100s is ARMv5, so we cannot share a single image.
Add the required symbols to multi_v5_defconfig, to give people some sane
default config when playing around with this chip. This is probably more
important as there are surely not many distros out there supporting
ARMv5 out of the box.
This allows my LicheePi Nano board to boot to a busybox prompt.

DSA ports are stacked devices, so they use dev_mc_add() to sync their
address list to their lower interface (DSA master). But they are also
hardware devices, so they program those addresses to hardware using the
__dev_mc_add() sync and unsync callbacks.
Unfortunately both cannot work at the same time, and it seems that the
multicast addresses which are already present on the DSA master, like
33:33:00:00:00:01 (added by addrconf.c as in6addr_linklocal_allnodes)
are synced to the master via dev_mc_sync(), but not to hardware by
__dev_mc_sync().
This happens because both the dev_mc_sync() -> __hw_addr_sync_one()
code path, as well as __dev_mc_sync() -> __hw_addr_sync_dev(), operate
on the same variable: ha->sync_cnt, in a way that causes the "sync"
method (dsa_slave_sync_mc) to no longer be called.
To fix the issue we need to work with the API in the way in which it was
intended to be used, and therefore, call dev_uc_add() and friends for
each individual hardware address, from the sync and unsync callbacks.
