Backmerge tag 'v6.4-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into drm-next
Linux 6.4-rc7
Need this to pull in the msm work.
Signed-off-by: Dave Airlie <airlied@redhat.com>
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.
Current release - regressions:
- wifi:
- cfg80211: fix double lock bug in reg_wdev_chan_valid()
- iwlwifi: mvm: spin_lock_bh() to fix lockdep regression
Current release - new code bugs:
- handshake: remove fput() that causes use-after-free
Previous releases - regressions:
- sched: cls_u32: fix reference counter leak leading to overflow
- sched: cls_api: fix lockup on flushing explicitly created chain
Previous releases - always broken:
- nf_tables: integrate pipapo into commit protocol
- nf_tables: incorrect error path handling with NFT_MSG_NEWRULE,
fix dangling pointer on failure
- ping6: fix send to link-local addresses with VRF
- sched: act_pedit: parse L3 header for L4 offset, the skb may
not have the offset saved
- sched: act_ct: fix promotion of offloaded unreplied tuple
- sched: refuse to destroy an ingress and clsact Qdiscs if there
are lockless change operations in flight
- wifi: mac80211: fix handful of bugs in multi-link operation
- ipvlan: fix bound dev checking for IPv6 l3s mode
- eth: enetc: correct the indexes of highest and 2nd highest TCs
- eth: ice: fix XDP memory leak when NIC is brought up and down
Misc:
- add deprecation notices for UDP-lite and DCCP
- selftests: mptcp: skip tests not supported by old kernels
- sctp: handle invalid error codes without calling BUG()

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.
Current release - regressions:
- wifi:
- cfg80211: fix double lock bug in reg_wdev_chan_valid()
- iwlwifi: mvm: spin_lock_bh() to fix lockdep regression
Current release - new code bugs:
- handshake: remove fput() that causes use-after-free
Previous releases - regressions:
- sched: cls_u32: fix reference counter leak leading to overflow
- sched: cls_api: fix lockup on flushing explicitly created chain
Previous releases - always broken:
- nf_tables: integrate pipapo into commit protocol
- nf_tables: incorrect error path handling with NFT_MSG_NEWRULE, fix
dangling pointer on failure
- ping6: fix send to link-local addresses with VRF
- sched: act_pedit: parse L3 header for L4 offset, the skb may not
have the offset saved
- sched: act_ct: fix promotion of offloaded unreplied tuple
- sched: refuse to destroy an ingress and clsact Qdiscs if there are
lockless change operations in flight
- wifi: mac80211: fix handful of bugs in multi-link operation
- ipvlan: fix bound dev checking for IPv6 l3s mode
- eth: enetc: correct the indexes of highest and 2nd highest TCs
- eth: ice: fix XDP memory leak when NIC is brought up and down
Misc:
- add deprecation notices for UDP-lite and DCCP
- selftests: mptcp: skip tests not supported by old kernels
- sctp: handle invalid error codes without calling BUG()"
* tag 'net-6.4-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (91 commits)
dccp: Print deprecation notice.
udplite: Print deprecation notice.
octeon_ep: Add missing check for ioremap

Commit e6c6ddb397 ("dt-bindings: clock: meson: add A1 PLL clock
controller bindings") adds a file entry with pattern
"include/dt-bindings/clock/a1*" to the ARM/Amlogic Meson SoC CLOCK
FRAMEWORK section. However, all header files added in the patch series to
add Amlogic A1 clock controller drivers carry the prefix "amlogic,a1", and
there are not header files matching "a1*".
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.
Adjust the pattern of this file entry to match the headers actually added.

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.

Michael is merging KVM PPC patches via the powerpc tree and KVM topic
branches. He doesn't necessarily have time to be across all of KVM so
is reluctant to call himself maintainer, but for the mechanics of how
patches flow upstream, it is maintained and does make sense to have
some contact people in MAINTAINERS.
So add Michael Ellerman as KVM PPC maintainer and myself as reviewer.

For convenience (less code duplication), the pin controller pin
configuration register values were defined in the bindings header.
These are not some IDs or other abstraction layer but raw numbers used
in the registers.
These constants do not fit the purpose of bindings. They do not
provide any abstraction, any hardware and driver independent ID. In
fact, the Linux pinctrl-single driver actually do not use the bindings
header at all.
Commit f2de003e14 ("dt-bindings: pinctrl: k3: Deprecate header with
register constants") already moved users to the local header, so, drop
the binding header. See background discussion in [1].
While at it, clean up the MAINTAINERS file which is the only reference
left.

Exposes consumer library functions providing support for interfaces
compatible with the venerable Intel 8254 Programmable Interval Timer
(PIT).
The Intel 8254 PIT first appeared in the early 1980s and was used
initially in IBM PC compatibles. The popularity of the original Intel
825x family of chips led to many subsequent variants and clones of the
interface in various chips and integrated circuits. Although still
popular, interfaces compatible with the Intel 8254 PIT are nowdays
typically found embedded in larger VLSI processing chips and FPGA
components rather than as discrete ICs.
A CONFIG_I8254 Kconfig option is introduced by this patch. Modules
wanting access to these i8254 library functions should select this
Kconfig option, and import the I8254 symbol namespace.

Hewlett-Packard (and some HP Compaq) business-class computers report
hardware monitoring information via WMI. This driver exposes that
information to hwmon.
Initial support is provided for temperature, fan speed, and intrusion
sensor types. Provisional support is provided for voltage and current
sensor types.
HP's WMI implementation permits many other types of numeric sensors.
Therefore, a debugfs interface is also provided to enumerate and
inspect all numeric sensors visible on the WMI side. This should
facilitate adding support for other sensor types in the future.
Tested on a HP Z420, a HP EliteOne 800 G1, and a HP Compaq Elite 8300
SFF.
Note that provisionally supported sensor types are untested and seem
to be rare-to-nonexistent in the wild, having been encountered
neither on test systems nor in ACPI dumps from the Linux Hardware
Database. They are included because their popularity in general makes
their presence on past or future HP systems plausible and because no
doubt exists as to how the sensors themselves would be represented in
WMI (alarm attributes will need to wait for hardware to be located).
A 2005 HP whitepaper gives the relevant sensor object MOF definition
and sensor value scaling calculation, and both this driver and the
official HP Performance Advisor utility comply with them (confirmed
in the latter case by reverse engineering).

We have a lot of different virtual media drivers, which can be used for
testing of the userspace applications and media subsystem middle layer.
However, all of them are aimed at testing the video functionality and
simulating the video devices. For audio devices we have only snd-dummy
module, which is good in simulating the correct behavior of an ALSA device.
I decided to write a tool, which would help to test the userspace ALSA
programs (and the PCM middle layer as well) under unusual circumstances
to figure out how they would behave. So I came up with this Virtual PCM
Test Driver.
This new Virtual PCM Test Driver has several features which can be useful
during the userspace ALSA applications testing/fuzzing, or testing/fuzzing
of the PCM middle layer. Not all of them can be implemented using the
existing virtual drivers (like dummy or loopback). Here is what can this
driver do:
- Simulate both capture and playback processes
- Generate random or pattern-based capture data
- Inject delays into the playback and capturing processes
- Inject errors during the PCM callbacks
Also, this driver can check the playback stream for containing the
predefined pattern, which is used in the corresponding selftest to check
the PCM middle layer data transferring functionality. Additionally, this
driver redefines the default RESET ioctl, and the selftest covers this PCM
API functionality as well.
The driver supports both interleaved and non-interleaved access modes, and
have separate pattern buffers for each channel. The driver supports up to
4 channels and up to 8 substreams.

There exists several examples today of devices that embed an ethernet
PHY or PCS directly inside an SoC. In this situation, either the device
is controlled through a vendor-specific register set, or sometimes
exposes the standard 802.3 registers that are typically accessed over
MDIO.
As phylib and phylink are designed to use mdiodevices, this driver
allows creating a virtual MDIO bus, that translates mdiodev register
accesses to regmap accesses.
The reason we use regmap is because there are at least 3 such devices
known today, 2 of them are Altera TSE PCS's, memory-mapped, exposed
with a 4-byte stride in stmmac's dwmac-socfpga variant, and a 2-byte
stride in altera-tse. The other one (nxp,sja1110-base-tx-mdio) is
exposed over SPI.

There have not been a lot of fixes for for the soc tree in 6.4, but
these have been sitting here for too long.
For the devicetree side, there is one minor warning fix for vexpress,
the rest all all for the the NXP i.MX platforms: SoC specific bugfixes
for the iMX8 clocks and its USB-3.0 gadget device, as well as board
specific fixes for regulators and the phy on some of the i.MX boards.
The microchip risc-v and arm32 maintainers now also add a shared
maintainer file entry for the arm64 parts.
The remaining fixes are all for firmware drivers, addressing mistakes in
the optee, scmi and ff-a firmware driver implementation, mostly in the
error handling code, incorrect use of the alloc_workqueue() interface in
SCMI, and compatibility with corner cases of the firmware implementation.

Merge tag 'vfs/v6.4-rc3/misc.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs fixes from Christian Brauner:
- During the acl rework we merged this cycle the generic_listxattr()
helper had to be modified in a way that in principle it would allow
for POSIX ACLs to be reported. At least that was the impression we
had initially. Because before the acl rework POSIX ACLs would be
reported if the filesystem did have POSIX ACL xattr handlers in
sb->s_xattr. That logic changed and now we can simply check whether
the superblock has SB_POSIXACL set and if the inode has
inode->i_{default_}acl set report the appropriate POSIX ACL name.
However, we didn't realize that generic_listxattr() was only ever
used by two filesystems. Both of them don't support POSIX ACLs via
sb->s_xattr handlers and so never reported POSIX ACLs via
generic_listxattr() even if they raised SB_POSIXACL and did contain
inodes which had acls set. The example here is nfs4.
As a result, generic_listxattr() suddenly started reporting POSIX
ACLs when it wouldn't have before. Since SB_POSIXACL implies that the
umask isn't stripped in the VFS nfs4 can't just drop SB_POSIXACL from
the superblock as it would also alter umask handling for them.
So just have generic_listxattr() not report POSIX ACLs as it never
did anyway. It's documented as such.
- Our SB_* flags currently use a signed integer and we shift the last
bit causing UBSAN to complain about undefined behavior. Switch to
using unsigned. While the original patch used an explicit unsigned
bitshift it's now pretty common to rely on the BIT() macro in a lot
of headers nowadays. So the patch has been adjusted to use that.
- Add Namjae as ntfs reviewer. They're already active this cycle so
let's make it explicit right now.

Krzysztof noticed that patches for arch/arm64/boot/dts/microchip were
getting lost & the listed tree was inactive.
Nicolas and I are willing to shepherd patches to Arnd, using the
existing at91 tree, so add a new entry covering
arch/arm64/boot/dts/microchip, listing us as maintainers.
Drop the tree from the existing sparx5 entry & narrow the devicetree
pattern to just sparx devices, leaving Lars, Steen and Daniel looking
after support for their SoCs.

It's hard to keep track of changes to the process docs.
Subsystem maintainers should probably know what's going on,
to ensure reasonably uniform developer experience across
trees.
We also need a place where process discussions can be held
(i.e. designated mailing list which can be CCed on naturally
arising discussions). I'm using workflows@ in this RFC,
but a new list may be better.
No change to the patch flow intended.

Commit a4422ff221 ("usb: typec: qcom: Add Qualcomm PMIC Type-C driver")
adds the section QUALCOMM TYPEC PORT MANAGER DRIVER in MAINTAINERS with
two file entries for header files in include/dt-bindings/usb/typec/.
However, these files are not added to the repository with this commit or
any commit in the related patch series. Probably, these file entries are
just needless leftover after the work went through some refactoring.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.
Remove the two file entries for non-existent header files.

Commit 361104b056 ("dt-bindings: mfd: Convert da9063 to yaml") converts
da9063.txt to dlg,da9063.yaml and adds a new file pattern in MAINTAINERS.
Unfortunately, the file pattern matches da90*.yaml, but the yaml file is
prefixed with dlg,da90.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken file pattern.
Repair this file pattern in DIALOG SEMICONDUCTOR DRIVERS.

v4: https://lore.kernel.org/all/20230413084253.1524-1-peter_hong@fintek.com.tw
1. Remove f81604_prepare_urbs/f81604_remove_urbs() and alloc URB/buffer
dynamically in f81604_register_urbs(), using "urbs_anchor" for manage
all rx/int URBs.
2. Add F81604 to MAINTAINERS list.
3. Change handle_clear_reg_work/handle_clear_overrun_work to single
clear_reg_work and using bitwise "clear_flags" to record it.
4. Move __f81604_set_termination in front of f81604_probe() to avoid
rarely racing condition.
5. Add __aligned to struct f81604_int_data / f81604_sff / f81604_eff.
6. Add aligned operations in f81604_start_xmit/f81604_process_rx_packet().
7. Change lots of CANBUS functions first parameter from struct usb_device*
to struct f81604_port_priv *priv. But remain f81604_write / f81604_read
/ f81604_update_bits() as struct usb_device* for
__f81604_set_termination() in probe() stage.
8. Simplify f81604_read_int_callback() and separate into
f81604_handle_tx / f81604_handle_can_bus_errors() functions.
v3: https://lore.kernel.org/all/20230327051048.11589-1-peter_hong@fintek.com.tw
1. Change CAN clock to using MEGA units.
2. Remove USB set/get retry, only remain SJA1000 reset/operation retry.
3. Fix all numberic constant to define.
4. Add terminator control. (only 0 & 120 ohm)
5. Using struct data to represent INT/TX/RX endpoints data instead byte
arrays.
6. Error message reports changed from %d to %pe for mnemotechnic values.

This commit adds a QCOM PMIC TCPM driver with an initial pm8150b
block.
The driver is layered as follows:
qcom_pmic_typec.c : Responsible for registering with TCPM and arbitrates
access to the Type-C and PDPHY hardware blocks in one
place. This presents a single TCPM device to device to
the Linux TCPM layer.
qcom_pmic_typec_pdphy.c: Responsible for interfacing with the PDPHY hardware and
processing power-delivery related calls from TCPM.
This hardware binding can be extended to
facilitate similar hardware in different PMICs.
qcom_pmic_typec_port.c: Responsible for notifying and processing Type-C
related calls from TCPM. Similar to the pdphy this
layer can be extended to handle the specifics of
different Qualcomm PMIC Type-C port managers.
This code provides all of the same functionality as the existing
qcom typec driver plus power-delivery as well.
As a result commit 6c8cf36951 ("usb: typec: Add QCOM PMIC typec detection
driver") can be deleted entirely.

MAINTAINERS: adjust file entry for ARM/APPLE MACHINE SUPPORT
media: dt-bindings: ov2685: Correct data-lanes attribute
It's been a few years since we've sorted this thing, and the end result
is that we've added MAINTAINERS entries in the wrong order, and a number
of entries have their fields in non-canonical order too.
So roll this boulder up the hill one more time by re-running
./scripts/parse-maintainers.pl --order
on it.
This file ends up being fairly painful for merge conflicts even
normally, since unlike almost all other kernel files it's one of those
"everybody touches the same thing", and re-ordering all entries is only
going to make that worse. But the alternative is to never do it at all,
and just let it all rot..
The rc2 week is likely the quietest and least painful time to do this.

the WMI driver core. The information regarding the ACPI interface

thermal: intel: powerclamp: Fix NULL pointer access issue
Commit 2b6a7409ac ("thermal: intel: menlow: Get rid of this driver")
removes the driver drivers/thermal/intel/intel_menlow.c, but misses to
remove its reference in MAINTAINERS.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.
Remove the INTEL MENLOW THERMAL DRIVER section in MAINTAINERS.

Core changes:
- Make a lot of pin controllers with GPIO and irqchips immutable,
i.e. not living structs, but const structs. This is driving a
changed initiated by the irqchip maintainers.
New drivers:
- New driver for the NXP S32 SoC pin controller
- As part of a thorough cleanup and restructuring of the
Ralink/Mediatek drivers, the Ralink MIPS pin control drivers
were folded into the Mediatek directory and the family is
renamed "mtmips". The Ralink chips live on as Mediatek MIPS
family where new variants can be added. As part of this work
also the device tree bindings were reworked.
- New subdriver for the Qualcomm SM7150 SoC.
- New subdriver for the Qualcomm IPQ9574 SoC.
- New driver for the nVidia BlueField-3 SoC.
- Support for the Qualcomm PMM8654AU mixed signal circuit GPIO.
- Support for the Qualcomm PMI632 mixed signal circuit GPIO.
Improvements:
- Add some missing pins and generic cleanups on the Renesas
r8a779g0 and r8a779g0 pin controllers. Generic Renesas
extension for power source selection on several SoCs.
- Misc cleanups for the Atmel AT91 and AT91-PIO4 pin
controllers
- Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi
driver.
- Several device tree binding cleanups as the binding
YAML syntax is solidifying.

More additions to the Rust core. Importantly, this adds the pin-init
API, which will be used by other abstractions, such as the
synchronization ones added here too:
- pin-init API: a solution for the safe pinned initialization problem.
This allows to reduce the need for 'unsafe' code in the kernel when
dealing with data structures that require a stable address. Commit
90e53c5e70 ("rust: add pin-init API core") contains a nice
introduction -- here is an example of how it looks like:
#[pin_data]
struct Example {
#[pin]
value: Mutex<u32>,
#[pin]
value_changed: CondVar,
}
impl Example {
fn new() -> impl PinInit<Self> {
pin_init!(Self {
value <- new_mutex!(0),
value_changed <- new_condvar!(),
})
}
}
// In a `Box`.
let b = Box::pin_init(Example::new())?;
// In the stack.
stack_pin_init!(let s = Example::new());
- 'sync' module: new types 'LockClassKey' ('struct lock_class_key'),
'Lock', 'Guard', 'Mutex' ('struct mutex'), 'SpinLock'
('spinlock_t'), 'LockedBy' and 'CondVar' (uses 'wait_queue_head_t'),
plus macros such as 'static_lock_class!' and 'new_spinlock!'.
In particular, 'Lock' and 'Guard' are generic implementations that
contain code that is common to all locks. Then, different backends
(the new 'Backend' trait) are implemented and used to define types
like 'Mutex':
type Mutex<T> = Lock<T, MutexBackend>;
In addition, new methods 'assume_init()', 'init_with()' and
'pin_init_with()' for 'UniqueArc<MaybeUninit<T>>' and 'downcast()'
for 'Arc<dyn Any + Send + Sync>'; as well as 'Debug' and 'Display'
implementations for 'Arc' and 'UniqueArc'. Reduced stack usage of
'UniqueArc::try_new_uninit()', too.
- 'types' module: new trait 'AlwaysRefCounted' and new type 'ARef'
(an owned reference to an always-reference-counted object, meant to
be used in wrappers for C types that have their own ref counting
functions).
Moreover, new associated functions 'raw_get()' and 'ffi_init()'
for 'Opaque'.
- New 'task' module with a new type 'Task' ('struct task_struct'), and
a new macro 'current!' to safely get a reference to the current one.
- New 'ioctl' module with new '_IOC*' const functions (equivalent to
the C macros).
- New 'uapi' crate, intended to be accessible by drivers directly.
- 'macros' crate: new 'quote!' macro (similar to the one provided in
userspace by the 'quote' crate); and the 'module!' macro now allows
specifying multiple module aliases.
- 'error' module: new associated functions for the 'Error' type,
such as 'from_errno()' and new functions such as 'to_result()'.
- 'alloc' crate: more fallible 'Vec' methods: 'try_resize` and
'try_extend_from_slice' and the infrastructure (imported from
the Rust standard library) they need.

are a couple patches to the core clk framework, but they're all basically
cleanups or debugging aids. The driver updates and new additions are dominated
in the diffstat by Qualcomm and MediaTek drivers. Qualcomm gained a handful of
new drivers for various SoCs, and MediaTek gained a bunch of drivers for
MT8188. The MediaTek drivers are being modernized as well, so there are
updates all over that vendor's clk drivers. There's also a couple other new clk
drivers in here, for example the Starfive JH7110 SoC support is added.
Outside of the two major SoC vendors though, we have the usual collection of
non-critical fixes and cleanups to various clk drivers. It's good to see that
we're getting more cleanups and modernization patches. Maybe one day we'll be
able to properly split clk providers from clk consumers.
Core:
- Print an informational message before disabling unused clks
New Drivers:
- BCM63268 timer clock and reset controller
- Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and

Updates:
- Shrink size of clk_fractional_divider a little
- Convert various clk drivers to devm_of_clk_add_hw_provider()
- Convert platform clk drivers to remove_new()
- Converted most Mediatek clock drivers to struct platform_driver

Pull clk updates from Stephen Boyd:
"Nothing looks out of the ordinary in this batch of clk driver updates.
There are a couple patches to the core clk framework, but they're all
basically cleanups or debugging aids. The driver updates and new
additions are dominated in the diffstat by Qualcomm and MediaTek
drivers. Qualcomm gained a handful of new drivers for various SoCs,
and MediaTek gained a bunch of drivers for MT8188. The MediaTek
drivers are being modernized as well, so there are updates all over
that vendor's clk drivers. There's also a couple other new clk drivers
in here, for example the Starfive JH7110 SoC support is added.
Outside of the two major SoC vendors though, we have the usual
collection of non-critical fixes and cleanups to various clk drivers.
It's good to see that we're getting more cleanups and modernization
patches. Maybe one day we'll be able to properly split clk providers
from clk consumers.
Core:
- Print an informational message before disabling unused clks
New Drivers:
- BCM63268 timer clock and reset controller
- Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and
MT8195 SoCs
- Mediatek MT8188 SoC clk drivers
- Clock driver for Sunplus SP7021 SoC
- Clk driver support for Loongson-2 SoCs
- Clock driver for Skyworks Si521xx I2C PCIe clock generators
- Initial Starfive JH7110 clk/reset support

MSM8917 and IPQ5332 SoCs
- GPU clock controller drivers for SM6115, SM6125, SM6375 and SA8775P
SoCs
Updates:
- Shrink size of clk_fractional_divider a little
- Convert various clk drivers to devm_of_clk_add_hw_provider()
- Convert platform clk drivers to remove_new()
- Converted most Mediatek clock drivers to struct platform_driver
- MediaTek clock drivers can be built as modules
- Reimplement Loongson-1 clk driver with DT support
- Migrate socfpga clk driver to of_clk_add_hw_provider()
- Support for i3c clks on Aspeed ast2600 SoCs

Now that we have platform-specific infrastructure for the dw i3c driver,
add platform support for the ASPEED AST2600 SoC.
The AST2600 has a small set of "i3c global" registers, providing
platform-level i3c configuration outside of the i3c core.
For the ast2600, we need a couple of extra setup operations:
- on probe: find the i3c global register set and parse the SDA pullup
resistor values
- on init: set the pullups accordingly, and set the i3c instance IDs

The summary of the changes for this pull requests is:
* Song Liu's new struct module_memory replacement
* Nick Alcock's MODULE_LICENSE() removal for non-modules
* My cleanups and enhancements to reduce the areas where we vmalloc
module memory for duplicates, and the respective debug code which
proves the remaining vmalloc pressure comes from userspace.
Most of the changes have been in linux-next for quite some time except
the minor fixes I made to check if a module was already loaded
prior to allocating the final module memory with vmalloc and the
respective debug code it introduces to help clarify the issue. Although
the functional change is small it is rather safe as it can only *help*
reduce vmalloc space for duplicates and is confirmed to fix a bootup
issue with over 400 CPUs with KASAN enabled. I don't expect stable
kernels to pick up that fix as the cleanups would have also had to have
been picked up. Folks on larger CPU systems with modules will want to
just upgrade if vmalloc space has been an issue on bootup.
Given the size of this request, here's some more elaborate details
on this pull request.
The functional change change in this pull request is the very first
patch from Song Liu which replaces the struct module_layout with a new
struct module memory. The old data structure tried to put together all
types of supported module memory types in one data structure, the new
one abstracts the differences in memory types in a module to allow each
one to provide their own set of details. This paves the way in the
future so we can deal with them in a cleaner way. If you look at changes
they also provide a nice cleanup of how we handle these different memory
areas in a module. This change has been in linux-next since before the
merge window opened for v6.3 so to provide more than a full kernel cycle
of testing. It's a good thing as quite a bit of fixes have been found
for it.
Jason Baron then made dynamic debug a first class citizen module user by
using module notifier callbacks to allocate / remove module specific
dynamic debug information.
Nick Alcock has done quite a bit of work cross-tree to remove module
license tags from things which cannot possibly be module at my request
so to:
a) help him with his longer term tooling goals which require a
deterministic evaluation if a piece a symbol code could ever be
part of a module or not. But quite recently it is has been made
clear that tooling is not the only one that would benefit.
Disambiguating symbols also helps efforts such as live patching,
kprobes and BPF, but for other reasons and R&D on this area
is active with no clear solution in sight.
b) help us inch closer to the now generally accepted long term goal
of automating all the MODULE_LICENSE() tags from SPDX license tags
In so far as a) is concerned, although module license tags are a no-op
for non-modules, tools which would want create a mapping of possible
modules can only rely on the module license tag after the commit
8b41fc4454 ("kbuild: create modules.builtin without Makefile.modbuiltin
or tristate.conf"). Nick has been working on this *for years* and
AFAICT I was the only one to suggest two alternatives to this approach
for tooling. The complexity in one of my suggested approaches lies in
that we'd need a possible-obj-m and a could-be-module which would check
if the object being built is part of any kconfig build which could ever
lead to it being part of a module, and if so define a new define
-DPOSSIBLE_MODULE [0]. A more obvious yet theoretical approach I've
suggested would be to have a tristate in kconfig imply the same new
-DPOSSIBLE_MODULE as well but that means getting kconfig symbol names
mapping to modules always, and I don't think that's the case today. I am
not aware of Nick or anyone exploring either of these options. Quite
recently Josh Poimboeuf has pointed out that live patching, kprobes and
BPF would benefit from resolving some part of the disambiguation as
well but for other reasons. The function granularity KASLR (fgkaslr)
patches were mentioned but Joe Lawrence has clarified this effort has
been dropped with no clear solution in sight [1].
In the meantime removing module license tags from code which could never
be modules is welcomed for both objectives mentioned above. Some
developers have also welcomed these changes as it has helped clarify
when a module was never possible and they forgot to clean this up,
and so you'll see quite a bit of Nick's patches in other pull
requests for this merge window. I just picked up the stragglers after
rc3. LWN has good coverage on the motivation behind this work [2] and
the typical cross-tree issues he ran into along the way. The only
concrete blocker issue he ran into was that we should not remove the
MODULE_LICENSE() tags from files which have no SPDX tags yet, even if
they can never be modules. Nick ended up giving up on his efforts due
to having to do this vetting and backlash he ran into from folks who
really did *not understand* the core of the issue nor were providing
any alternative / guidance. I've gone through his changes and dropped
the patches which dropped the module license tags where an SPDX
license tag was missing, it only consisted of 11 drivers. To see
if a pull request deals with a file which lacks SPDX tags you
can just use:
./scripts/spdxcheck.py -f \
$(git diff --name-only commid-id | xargs echo)
You'll see a core module file in this pull request for the above,
but that's not related to his changes. WE just need to add the SPDX
license tag for the kernel/module/kmod.c file in the future but
it demonstrates the effectiveness of the script.
Most of Nick's changes were spread out through different trees,
and I just picked up the slack after rc3 for the last kernel was out.
Those changes have been in linux-next for over two weeks.
The cleanups, debug code I added and final fix I added for modules
were motivated by David Hildenbrand's report of boot failing on
a systems with over 400 CPUs when KASAN was enabled due to running
out of virtual memory space. Although the functional change only
consists of 3 lines in the patch "module: avoid allocation if module is
already present and ready", proving that this was the best we can
do on the modules side took quite a bit of effort and new debug code.
The initial cleanups I did on the modules side of things has been
in linux-next since around rc3 of the last kernel, the actual final
fix for and debug code however have only been in linux-next for about a
week or so but I think it is worth getting that code in for this merge
window as it does help fix / prove / evaluate the issues reported
with larger number of CPUs. Userspace is not yet fixed as it is taking
a bit of time for folks to understand the crux of the issue and find a
proper resolution. Worst come to worst, I have a kludge-of-concept [3]
of how to make kernel_read*() calls for modules unique / converge them,
but I'm currently inclined to just see if userspace can fix this
instead.

Here is the "big" set of char/misc and other driver subsystems for
6.4-rc1.
It's pretty big, but due to the removal of pcmcia drivers, almost breaks
even for number of lines added vs. removed, a nice change.
Included in here are:
- removal of unused PCMCIA drivers (finally!)
- Interconnect driver updates and additions
- Lots of IIO driver updates and additions
- MHI driver updates
- Coresight driver updates
- NVMEM driver updates, which required some OF updates
- W1 driver updates and a new maintainer to manage the subsystem

"Here is the "big" set of char/misc and other driver subsystems for
6.4-rc1.
It's pretty big, but due to the removal of pcmcia drivers, almost
breaks even for number of lines added vs. removed, a nice change.
Included in here are:
- removal of unused PCMCIA drivers (finally!)
- Interconnect driver updates and additions
- Lots of IIO driver updates and additions
- MHI driver updates
- Coresight driver updates
- NVMEM driver updates, which required some OF updates
- W1 driver updates and a new maintainer to manage the subsystem
- FPGA driver updates
- New driver subsystem, CDX, for AMD systems
- lots of other small driver updates and additions
All of these have been in linux-next for a while with no reported

Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening in
the driver core in the quest to be able to move "struct bus" and "struct
class" into read-only memory, a task now complete with these changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules for
all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most of
them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.
All of these have been in linux-next for a while with no reported
problems.

The pull request includes a few changes, Its main purpose is to prepare
for my future work by taking over maintainership from Stefan Richter. I
have plans to work on several items; e.g. packet processing in workqueue
context instead of tasklet.
As you may be aware, the IEEE 1394 technology is outdated. However, we
still have users. It is better to ensure a smooth transition for the users
to shift to other categories of devices. The first commit includes my
schedule to maintain the subsystem for the next six years. I would
appreciate your assistance throughout this period.

MAINTAINERS: replace maintainer of FireWire subsystem
A fairly standard release for SPI with the exception of a change to the
API for specifying chip selects done in preparation for supporting
devices with more than one chip select, this required some mechanical
changes throughout the tree which have been cooking in -next happily for
a while. There's also a new API to allow us to TPM chips on half duplex
controllers.
There's three commits in here that were mangled by a bad interaction
between the alsa-devel mailing list software and b4, I didn't notice
until there were merges on top with it being SPI not ALSA. It seemed
clear enough to not be worth going back and fixing.
- Refactoring in preparation for supporting multiple chip selects for a
single device, needed by some flash devices, which required a change
in the SPI device API visible throughout the tree.
- Support for hardware assisted interaction with SPI TPMs on half
duplex controllers, implemented on nVidia Tedra210 QuadSPI.
- Optimisation for large transfers on fsl-cpm devices.
- Cleanups around device property use which fix some sisues with
fwnode.
- Use of both void remove() and devm_platform_.*ioremap_resource().
- Support for AMD Pensando Elba, Amlogic A1, Cadence device mode,
Intel MetorLake-S and StarFive J7110 QuadSPI.
The final commit converting to DEV_PM_OPS() was applied late to fix a
warning that was introduced by some of the earlier work.

At this time, it's an interesting mixture of changes for both old and
new stuff. Majority of changes are about ASoC (lots of systematic
changes for converting remove callbacks to void, and cleanups), while
we got the fixes and the enhancements of very old PCI cards, too.
Here are some highlights:
ALSA/ASoC Core:
- Continued effort of more ASoC core cleanups
- Minor improvements for XRUN handling in indirect PCM helpers
- Code refactoring of PCM core code
ASoC:
- Continued feature and simplification work on SOF, including addition
of a no-DSP mode for bringup, HDA MLink and extensions to the IPC4
protocol
- Hibernation support for CS35L45
- More DT binding conversions
- Support for Cirrus Logic CS35L56, Freescale QMC, Maxim MAX98363,

Core
----
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances.
- Reduce compound page head access for zero-copy data transfers.
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible.
- Threaded NAPI improvements, adding defer skb free support and unneeded
softirq avoidance.
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking.
- Add lockless accesses annotation to sk_err[_soft].
- Optimize again the skb struct layout.
- Extends the skb drop reasons to make it usable by multiple
subsystems.
- Better const qualifier awareness for socket casts.
BPF
---
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and variable-sized
accesses.
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward.
- Add more precise memory usage reporting for all BPF map types.
- Adds support for using {FOU,GUE} encap with an ipip device operating
in collect_md mode and add a set of BPF kfuncs for controlling encap
params.
- Allow BPF programs to detect at load time whether a particular kfunc
exists or not, and also add support for this in light skeleton.
- Bigger batch of BPF verifier improvements to prepare for upcoming BPF
open-coded iterators allowing for less restrictive looping capabilities.
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF
programs to NULL-check before passing such pointers into kfunc.
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in
local storage maps.
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps.
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree.
- Add BPF verifier support for ST instructions in convert_ctx_access()
which will help new -mcpu=v4 clang flag to start emitting them.
- Add ARM32 USDT support to libbpf.
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations.
Protocols
---------
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address.
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition.
- Add the handshake upcall mechanism, allowing the user-space
to implement generic TLS handshake on kernel's behalf.
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures.
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers.
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction.
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore.
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter
---------
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged.
- Update bridge netfilter and ovs conntrack helpers to handle
IPv6 Jumbo packets properly, i.e. fetch the packet length
from hop-by-hop extension header. This is needed for BIT TCP
support.
- The iptables 32bit compat interface isn't compiled in by default
anymore.
- Move ip(6)tables builtin icmp matches to the udptcp one.
This has the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used.
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device.
Driver API
----------
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time.
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them.
- Allow the page_pool to directly recycle the pages from safely
localized NAPI.
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization.
- Add YNL support for user headers and struct attrs.
- Add partial YNL specification for devlink.
- Add partial YNL specification for ethtool.
- Add tc-mqprio and tc-taprio support for preemptible traffic classes.

Merge tag 'net-next-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"Core:
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances
- Reduce compound page head access for zero-copy data transfers
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
possible
- Threaded NAPI improvements, adding defer skb free support and
unneeded softirq avoidance
- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking
- Add lockless accesses annotation to sk_err[_soft]
- Optimize again the skb struct layout
- Extends the skb drop reasons to make it usable by multiple
subsystems
- Better const qualifier awareness for socket casts
BPF:
- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and
variable-sized accesses
- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward
- Add more precise memory usage reporting for all BPF map types
- Adds support for using {FOU,GUE} encap with an ipip device
operating in collect_md mode and add a set of BPF kfuncs for
controlling encap params
- Allow BPF programs to detect at load time whether a particular
kfunc exists or not, and also add support for this in light
skeleton
- Bigger batch of BPF verifier improvements to prepare for upcoming
BPF open-coded iterators allowing for less restrictive looping
capabilities
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce
BPF programs to NULL-check before passing such pointers into kfunc
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
in local storage maps
- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps
- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree
- Add BPF verifier support for ST instructions in
convert_ctx_access() which will help new -mcpu=v4 clang flag to
start emitting them
- Add ARM32 USDT support to libbpf
- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations
Protocols:
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition
- Add the handshake upcall mechanism, allowing the user-space to
implement generic TLS handshake on kernel's behalf
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures
- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers
- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction
- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore
- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support
Netfilter:
- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged
- Update bridge netfilter and ovs conntrack helpers to handle IPv6
Jumbo packets properly, i.e. fetch the packet length from
hop-by-hop extension header. This is needed for BIT TCP support
- The iptables 32bit compat interface isn't compiled in by default
anymore
- Move ip(6)tables builtin icmp matches to the udptcp one. This has
the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used
- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device
Driver API:
- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time
- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them
- Allow the page_pool to directly recycle the pages from safely
localized NAPI
- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization
- Add YNL support for user headers and struct attrs
- Add partial YNL specification for devlink
- Add partial YNL specification for ethtool
- Add tc-mqprio and tc-taprio support for preemptible traffic classes
- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device
- Add basic LED support for switch/phy
- Add NAPI documentation, stop relaying on external links
- Convert dsa_master_ioctl() to netdev notifier. This is a
preparatory work to make the hardware timestamping layer selectable
by user space
- Add transceiver support and improve the error messages for CAN-FD
controllers
