There's nothing controversial in here and almost everything has been
in next for more than a week (95% a lot longer than this). The only
thing that has spent less time in next is a new driver so no risk of
regressions.

SoC support. Instead there's a treewide patch series from Maxime that makes
clk_ops::determine_rate mandatory for muxes. Beyond that core framework change
we have the usual pile of clk driver updates such as migrating i2c drivers to
use .probe() again or YAMLfication of clk DT bindings so we can validate DTBs.
Overall the SoCs that got the most updates this time around in terms of
diffstat are the Amlogic and Mediatek drivers because they added new SoC
support or fixed up various drivers to have proper data.
In general things look kinda quiet. I suspect the core framework change may
still shake out some problems after the merge window, mostly because not
everyone tests linux-next where that series has been for some number of weeks.
I saw that there's at least one pending fix for Tegra that needs to be wrapped
up into a proper patch. I'll try to catch those bits before the window closes
so that -rc1 is bootable. More details below.
Core:
- Make clk_ops::determine_rate mandatory for muxes
New Drivers:
- Add amlogic a1 SoC family PLL and peripheral clock controller support
Updates:
- Handle allocation failures from kasprintf() and friends
- Migrate platform clk drivers to .remove_new()
- Migrate i2c clk drivers to .probe() instead of .probe_new()
- Remove CLK_SET_PARENT from all Mediatek MSDC core clocks
- Add infra_ao reset support for Mediatek MT8188 SoCs
- Align driver_data to i2c_device_id tables in some i2c clk drivers
- Use device_get_match_data() in vc5 clk driver
- New Kconfig symbol name (SOC_MICROCHIP_POLARFIRE) for Microchip FPGA clock
drivers
- Use of_property_read_bool() to read "microchip,pic32mzda-sosc" boolean DT
property in clk-pic32mzda
- Convert AT91 clock dt-bindings to YAML
- Remove CLK_SET_RATE_PARENT flag from LDB clocks on i.MX6SX
- Keep i.MX UART clocks enabled during kernel boot if earlycon is set
- Drop imx_unregister_clocks() as there are no users anymore
- Switch to _safe iterator on imx_clk_scu_unregister() to avoid use after free
- Add determine_rate op to the imx8m composite clock
- Use device managed API for iomap and kzalloc for i.MXRT1050, i.MX8MN,
i.MX8MP and i.MX93 clock controller drivers
- Add missing interrupt DT property for the i.MX8M clock controller
- Re-add support for Exynos4212 clock controller because we are
re-introducing the SoC in the mainline
- Add CONFIG_OF dependency to Samsung clk Kconfig symbols to solve some
objtool warnings
- Preselect PLL MIPI as TCON0 parent for Allwinner A64 SoC
- Convert the Renesas clock drivers to readl_poll_timeout_atomic()
- Add PWM clock on Renesas R-Car V3U
- Fix PLL5 on Renesas RZ/G2L and RZ/V2L

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).
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge).
- Support matching on Connectivity Fault Management (CFM) packets.
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug.
- HSR: don't enable promiscuous mode if device offloads the proto.
- Support active scanning in IEEE 802.15.4.
- Continue work on Multi-Link Operation for WiFi 7.
BPF
---
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used,
or in fact passing the verifier at all for complex programs,
especially those using open-coded iterators.
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what
the output buffer *should* be, without writing anything.
- Accept dynptr memory as memory arguments passed to helpers.
- Add routing table ID to bpf_fib_lookup BPF helper.
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only).
- Show target_{obj,btf}_id in tracing link fdinfo.
- Addition of several new kfuncs (most of the names are 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()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter
---------
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value.
- Increase ip_vs_conn_tab_bits range for 64BIT builds.
- Allow updating size of a set.
- Improve NAT tuple selection when connection is closing.
Driver API
----------
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out).
- Support configuring rate selection pins of SFP modules.
- 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).
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message.
- Split devlink instance and devlink port operations.

Pull hardening updates from Kees Cook:
"There are three areas of note:
A bunch of strlcpy()->strscpy() conversions ended up living in my tree
since they were either Acked by maintainers for me to carry, or got
ignored for multiple weeks (and were trivial changes).
The compiler option '-fstrict-flex-arrays=3' has been enabled
globally, and has been in -next for the entire devel cycle. This
changes compiler diagnostics (though mainly just -Warray-bounds which
is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_
coverage. In other words, there are no new restrictions, just
potentially new warnings. Any new FORTIFY warnings we've seen have
been fixed (usually in their respective subsystem trees). For more
details, see commit df8fc4e934.
The under-development compiler attribute __counted_by has been added
so that we can start annotating flexible array members with their
associated structure member that tracks the count of flexible array
elements at run-time. It is possible (likely?) that the exact syntax
of the attribute will change before it is finalized, but GCC and Clang
are working together to sort it out. Any changes can be made to the
macro while we continue to add annotations.
As an example of that last case, I have a treewide commit waiting with
such annotations found via Coccinelle:
https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b
Also see commit dd06e72e68 for more details.

Pull lsm updates from Paul Moore:
- A SafeSetID patch to correct what appears to be a cut-n-paste typo in
the code causing a UID to be printed where a GID was desired.
This is coming via the LSM tree because we haven't been able to get a
response from the SafeSetID maintainer (Micah Morton) in several
months. Hopefully we are able to get in touch with Micah, but until
we do I'm going to pick them up in the LSM tree.
- A small fix to the reiserfs LSM xattr code.
We're continuing to work through some issues with the reiserfs code
as we try to fixup the LSM xattr handling, but in the process we're
uncovering some ugly problems in reiserfs and we may just end up
removing the LSM xattr support in reiserfs prior to reiserfs'
removal.
For better or worse, this shouldn't impact any of the reiserfs users,
as we discovered that LSM xattrs on reiserfs were completely broken,
meaning no one is currently using the combo of reiserfs and a file
labeling LSM.
- A tweak to how the cap_user_data_t struct/typedef is declared in the
header file to appease the Sparse gods.
- In the process of trying to sort out the SafeSetID lost-maintainer
problem I realized that I needed to update the labeled networking
entry to "Supported".
- Minor comment/documentation and spelling fixes.

This pull contains the following branches:
doc.2023.05.10a: Documentation updates
fixes.2023.05.11a: Miscellaneous fixes, perhaps most notably:
o Remove RCU_NONIDLE(). The new visibility of most of the idle
loop to RCU has obsoleted this API.
o Make the RCU_SOFTIRQ callback-invocation time limit also apply
to the rcuc kthreads that invoke callbacks for CONFIG_PREEMPT_RT.
o Add a jiffies-based callback-invocation time limit to handle
long-running callbacks. (The local_clock() function is only
invoked once per 32 callbacks due to its high overhead.)
o Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs,
which fixes a bug that can occur on systems with non-contiguous
CPU numbering.
kvfree.2023.05.10a: kvfree_rcu updates
o Eliminate the single-argument variant of k[v]free_rcu() now
that all uses have been converted to k[v]free_rcu_mightsleep().
o Add WARN_ON_ONCE() checks for k[v]free_rcu*() freeing callbacks
too soon. Yes, this is closing the barn door after the horse

Pull RCU updates from Paul McKenney:
"Documentation updates
Miscellaneous fixes, perhaps most notably:
- Remove RCU_NONIDLE(). The new visibility of most of the idle loop
to RCU has obsoleted this API.
- Make the RCU_SOFTIRQ callback-invocation time limit also apply to
the rcuc kthreads that invoke callbacks for CONFIG_PREEMPT_RT.
- Add a jiffies-based callback-invocation time limit to handle
long-running callbacks. (The local_clock() function is only invoked
once per 32 callbacks due to its high overhead.)
- Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs, which
fixes a bug that can occur on systems with non-contiguous CPU
numbering.
kvfree_rcu updates:
- Eliminate the single-argument variant of k[v]free_rcu() now that
all uses have been converted to k[v]free_rcu_mightsleep().
- Add WARN_ON_ONCE() checks for k[v]free_rcu*() freeing callbacks too
soon. Yes, this is closing the barn door after the horse has
escaped, but Murphy says that there will be more horses.
Callback-offloading updates:
- Fix a number of bugs involving the shrinker and lazy callbacks.

- Parallel CPU bringup
The reason why people are interested in parallel bringup is to shorten
the (kexec) reboot time of cloud servers to reduce the downtime of the
VM tenants.
The current fully serialized bringup does the following per AP:
1) Prepare callbacks (allocate, intialize, create threads)
2) Kick the AP alive (e.g. INIT/SIPI on x86)
3) Wait for the AP to report alive state
4) Let the AP continue through the atomic bringup
5) Let the AP run the threaded bringup to full online state
There are two significant delays:
#3 The time for an AP to report alive state in start_secondary() on
x86 has been measured in the range between 350us and 3.5ms
depending on vendor and CPU type, BIOS microcode size etc.
#4 The atomic bringup does the microcode update. This has been
measured to take up to ~8ms on the primary threads depending on
the microcode patch size to apply.
On a two socket SKL server with 56 cores (112 threads) the boot CPU
spends on current mainline about 800ms busy waiting for the APs to come
up and apply microcode. That's more than 80% of the actual onlining
procedure.
This can be reduced significantly by splitting the bringup mechanism
into two parts:
1) Run the prepare callbacks and kick the AP alive for each AP which
needs to be brought up.
The APs wake up, do their firmware initialization and run the low
level kernel startup code including microcode loading in parallel
up to the first synchronization point. (#1 and #2 above)
2) Run the rest of the bringup code strictly serialized per CPU
(#3 - #5 above) as it's done today.
Parallelizing that stage of the CPU bringup might be possible in
theory, but it's questionable whether required surgery would be
justified for a pretty small gain.
If the system is large enough the first AP is already waiting at the
first synchronization point when the boot CPU finished the wake-up of
the last AP. That reduces the AP bringup time on that SKL from ~800ms
to ~80ms, i.e. by a factor ~10x.
The actual gain varies wildly depending on the system, CPU, microcode
patch size and other factors. There are some opportunities to reduce
the overhead further, but that needs some deep surgery in the x86 CPU
bringup code.
For now this is only enabled on x86, but the core functionality
obviously works for all SMP capable architectures.
- Enhancements for SMP function call tracing so it is possible to locate
the scheduling and the actual execution points. That allows to measure
IPI delivery time precisely.

There was also an incorrect reference to dma-names being "rxtx" where

this is corrected in the conversion.

- Fix MAINTAINERS file to point to proper mailing list for rtla and rv
The mailing list pointed to linux-trace-devel instead of
linux-trace-kernel. The former is for the tracing libraries
and the latter is for anything in the Linux kernel tree.
The wrong mailing list was used because linux-trace-kernel did not
exist when rtla and rv were created.
- User events:
. Fix matching of dynamic events to their user events
When user writes to dynamic_events file, a lookup of the
registered dynamic events are made, but there were some cases
that a match could be incorrectly made.
. Add auto cleanup of user events
Have the user events automatically get removed when the last
reference (file descriptor) is closed. This was asked for to
prevent leaks of user events hanging around needing admins
to clean them up.
. Add persistent logic (but not let user space use it yet)
In some cases, having a persistent user event (one that does not
get cleaned up automatically) is useful. But there's still
debates about how to expose this to user space. The infrastructure
is added, but the API is not.
. Update the selftests
Update the user event selftests to reflect the above changes.

Per-VMA locking allows us to lock a struct vm_area_struct without
taking the process-wide mmap lock in read mode.
Consider a process workload where the mmap lock is taken constantly in
write mode. In this scenario, all zerocopy receives are periodically
blocked during that period of time - though in principle, the memory
ranges being used by TCP are not touched by the operations that need
the mmap write lock. This results in performance degradation.
Now consider another workload where the mmap lock is never taken in
write mode, but there are many TCP connections using receive zerocopy
that are concurrently receiving. These connections all take the mmap
lock in read mode, but this does induce a lot of contention and atomic
ops for this process-wide lock. This results in additional CPU
overhead caused by contending on the cache line for this lock.
However, with per-vma locking, both of these problems can be avoided.
As a test, I ran an RPC-style request/response workload with 4KB
payloads and receive zerocopy enabled, with 100 simultaneous TCP
connections. I measured perf cycles within the
find_tcp_vma/mmap_read_lock/mmap_read_unlock codepath, with and
without per-vma locking enabled.
When using process-wide mmap semaphore read locking, about 1% of
measured perf cycles were within this path. With per-VMA locking, this
value dropped to about 0.45%.

Selftests excluded - we have 58 patches and diff of +442/-199,
which isn't really small but perhaps with the exception of
the WiFi locking change it's old(ish) bugs.
We have no known problems with v6.4.
The selftest changes are rather large as MPTCP folks try to apply
Greg's guidance that selftest from torvalds/linux should be able
to run against stable kernels.
Last thing I should call out is the DCCP/UDP-lite deprecation notices,
we are fairly sure those are dead, but if we're wrong reverting them
back in won't be fun.

Add support for TPS65219 PMICs GPIO interface.
3 GPIO pins:
- GPIO0 only is IO but input mode reserved for MULTI_DEVICE_ENABLE usage.
- GPIO1 and GPIO2 are Output only and referred as GPO1 and GPO2 in spec.
GPIO0 is statically configured as input or output prior to Linux boot.
it is used for MULTI_DEVICE_ENABLE function.
This setting is statically configured by NVM.
GPIO0 can't be used as a generic GPIO (specification Table 8-34).
It's either a GPO when MULTI_DEVICE_EN=0 or a GPI when MULTI_DEVICE_EN=1.
Datasheet describes specific usage for non standard GPIO.

At LFS 2023, it was suggested we should publicly document the name and
email of reviewers who new contributors can trust. This also gives them
some recognition for their work as reviewers.

Some of MediaTek's Filogic SoCs come with built-in gigabit Ethernet
PHYs which require calibration data from the SoC's efuse.
Despite the similar design the driver doesn't share any code with the
existing mediatek-ge.c.
Add support for such PHYs by introducing a new driver with basic
support for MediaTek SoCs MT7981 and MT7988 built-in 1GE PHYs.
