Jisheng Zhang <jszhang@kernel.org> says:
When trying to run linux with various opensource riscv core on
resource limited FPGA platforms, for example, those FPGAs with less
than 16MB SDRAM, I want to save mem as much as possible. One of the
major technologies is kernel size optimizations, I found that riscv
does not currently support HAVE_LD_DEAD_CODE_DATA_ELIMINATION, which
passes -fdata-sections, -ffunction-sections to CFLAGS and passes the
--gc-sections flag to the linker.
This not only benefits my case on FPGA but also benefits defconfigs.
Here are some notable improvements from enabling this with defconfigs:
nommu_k210_defconfig:
text data bss dec hex
1112009 410288 59837 1582134 182436 before
962838 376656 51285 1390779 1538bb after
rv32_defconfig:
text data bss dec hex
8804455 2816544 290577 11911576 b5c198 before
8692295 2779872 288977 11761144 b375f8 after
defconfig:
text data bss dec hex
9438267 3391332 485333 13314932 cb2b74 before
9285914 3350052 483349 13119315 c82f53 after
patch1 and patch2 are clean ups.
patch3 fixes a typo.
patch4 finally enable HAVE_LD_DEAD_CODE_DATA_ELIMINATION for riscv.
* b4-shazam-merge:
riscv: disable HAVE_LD_DEAD_CODE_DATA_ELIMINATION for LLD
riscv: enable HAVE_LD_DEAD_CODE_DATA_ELIMINATION
vmlinux.lds.h: use correct .init.data.* section name
riscv: vmlinux-xip.lds.S: remove .alternative section
riscv: move options to keep entries sorted
riscv: Fix orphan section warnings caused by kernel/pi

KVM/arm64 updates for 6.5
- Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of block splitting in the stage-2
fault path.
- Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
services that live in the Secure world. pKVM intervenes on FF-A calls
to guarantee the host doesn't misuse memory donated to the hyp or a
pKVM guest.
- Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.
- Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set configuration
from userspace, but the intent is to relax this limitation and allow
userspace to select a feature set consistent with the CPU.
- Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.
- Use a separate set of pointer authentication keys for the hypervisor
when running in protected mode, as the host is untrusted at runtime.
- Ensure timer IRQs are consistently released in the init failure
paths.
- Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
(FEAT_EVT), as it is a register commonly read from userspace.
- Erratum workaround for the upcoming AmpereOne part, which has broken
hardware A/D state management.
As a consequence of the hVHE series reworking the arm64 software
features framework, the for-next/module-alloc branch from the arm64 tree
comes along for the ride.

It turns out that xtensa has a really odd configuration situation: you
can do a no-MMU config, but still have the page fault code enabled.
Which doesn't sound all that sensible, but it turns out that xtensa can
have protection faults even without the MMU, and we have this:
config PFAULT
bool "Handle protection faults" if EXPERT && !MMU
default y
help
Handle protection faults. MMU configurations must enable it.
noMMU configurations may disable it if used memory map never
generates protection faults or faults are always fatal.
If unsure, say Y.
which completely violated my expectations of the page fault handling.
End result: Guenter reports that the xtensa no-MMU builds all fail with
arch/xtensa/mm/fault.c: In function ‘do_page_fault’:
arch/xtensa/mm/fault.c:133:8: error: implicit declaration of function ‘lock_mm_and_find_vma’
because I never exposed the new lock_mm_and_find_vma() function for the
no-MMU case.
Doing so is simple enough, and fixes the problem.

The root cause is, inodeA references inodeB via inodeB's ino, once inodeA
is truncated, it calls truncate_dnode() to truncate data blocks in inodeB's
node page, it traverse mapping data from node->i.i_addr[0] to
node->i.i_addr[ADDRS_PER_BLOCK() - 1], result in out-of-boundary access.
This patch fixes to add sanity check on dnode page in truncate_dnode(),
so that, it can help to avoid triggering such issue, and once it encounters
such issue, it will record newly introduced ERROR_INVALID_NODE_REFERENCE
error into superblock, later fsck can detect such issue and try repairing.
Also, it removes f2fs_truncate_data_blocks() for cleanup due to the
function has only one caller, and uses f2fs_truncate_data_blocks_range()
instead.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Export pcie_retrain_link() for use outside ASPM
- Add Data Link Layer Link Active Reporting as another way for
pcie_retrain_link() to determine the link is up
- Work around link training failures (especially on the ASMedia
ASM2824 switch) by training first at 2.5GT/s and then attempting
higher rates
Resource management:
- When we coalesce host bridge windows, remove invalidated resources
from the resource tree so future allocations work correctly
Hotplug:
- Cancel bringup sequence if card is not present, to keep from
blinking Power Indicator indefinitely
- Reassign bridge resources if necessary for ACPI hotplug
Driver binding:
- Convert platform_device .remove() callbacks to return void instead
of a mostly useless int
Power management:
- Reduce wait time for secondary bus to be ready to speed up resume
- Avoid putting EloPOS E2/S2/H2 (as well as Elo i2) PCIe Ports in
D3cold
- Call _REG when transitioning D-states so AML that uses the PCI
config space OpRegion works, which fixes some ASMedia GPIO
controllers after resume
Virtualization:
- Delay extra 250ms after FLR of Solidigm P44 Pro NVMe to avoid KVM
hang when guest is rebooted
- Add function 1 DMA alias quirk for Marvell 88SE9235
Error handling:
- Unexport pci_save_aer_state() since it's only used in drivers/pci/
- Drop recommendation for drivers to configure AER Capability, since
the PCI core does this for all devices
ASPM:
- Disable ASPM on MFD function removal to avoid use-after-free
- Tighten up pci_enable_link_state() and pci_disable_link_state()
interfaces so they don't enable/disable states the driver didn't
specify
- Avoid link retraining race that can happen if ASPM sets link
control parameters while the link is in the midst of training for
some other reason
Endpoint framework:
- Change "PCI Endpoint Virtual NTB driver" Kconfig prompt to be
different from "PCI Endpoint NTB driver"
- Automatically create a function specific attributes group for
endpoint drivers to avoid reference counting issues
- Fix many EPC test issues
- Return pci_epf_type_add_cfs() error if EPF has no driver
- Add kernel-doc for pci_epc_raise_irq() and pci_epc_map_msi_irq()
MSI vector parameters
- Pass EPF device ID to driver probe functions
- Return -EALREADY if EPC has already been started/stopped
- Add linkdown notifier support and use it in qcom-ep
- Add Bus Master Enable event support and use it in qcom-ep
- Add Qualcomm Modem Host Interface (MHI) endpoint driver
- Add Layerscape PME interrupt handling to manage link-up
notification
Cadence PCIe controller driver:
- Wait for link retrain to complete when working around the J721E
i2085 erratum with Gen2 mode
Faraday FTPC100 PCI controller driver:
- Release clock resources on error paths
Freescale i.MX6 PCIe controller driver:
- Save and restore Root Port MSI control to work around hardware defect
Intel VMD host bridge driver:
- Reset VMD config register between soft reboots
- Capture pci_reset_bus() return value instead of printing junk when
it fails
Qualcomm PCIe controller driver:
- Add SDX65 endpoint compatible string to DT binding
- Disable register write access after init for IP v2.3.3, v2.9.0
- Use DWC helpers for enabling/disabling writes to DBI registers
- Hide slot hotplug capability for IP v1.0.0, v1.9.0, v2.1.0, v2.3.2,
v2.3.3, v2.7.0, v2.9.0
- Reuse v2.3.2 post-init sequence for v2.4.0
Renesas R-Car PCIe controller driver:
- Remove unused static pcie_base and pcie_dev
Rockchip PCIe controller driver:
- Remove writes to unused registers
- Write endpoint Device ID using correct register
- Assert PCI Configuration Enable bit after probe so endpoint
responds instead of generating Request Retry Status messages
- Poll waiting for PHY PLLs to lock
- Update RK3399 example DT binding to be valid
- Use RK3399 PCIE_CLIENT_LEGACY_INT_CTRL to generate INTx instead of
manually generating PCIe message
- Use multiple windows to avoid address translation conflicts
- Use u32 (not u16) when accessing 32-bit registers
- Hide MSI-X Capability, since RK3399 can't generate MSI-X
- Set endpoint controller required alignment to 256
Synopsys DesignWare PCIe controller driver:
- Wait for link to come up only if we've initiated link training
Miscellaneous:
- Add pci_clear_master() stub for non-CONFIG_PCI"

Pull probes updates from Masami Hiramatsu:
- fprobe: Pass return address to the fprobe entry/exit callbacks so
that the callbacks don't need to analyze pt_regs/stack to find the
function return address.
- kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN
flags so that those are not set at once.
- fprobe events:
- Add a new fprobe events for tracing arbitrary function entry and
exit as a trace event.
- Add a new tracepoint events for tracing raw tracepoint as a
trace event. This allows user to trace non user-exposed
tracepoints.
- Move eprobe's event parser code into probe event common file.
- Introduce BTF (BPF type format) support to kernel probe (kprobe,
fprobe and tracepoint probe) events so that user can specify
traced function arguments by name. This also applies the type of
argument when fetching the argument.
- Introduce '$arg*' wildcard support if BTF is available. This
expands the '$arg*' meta argument to all function argument
automatically.
- Check the return value types by BTF. If the function returns
'void', '$retval' is rejected.
- Add some selftest script for fprobe events, tracepoint events
and BTF support.
- Update documentation about the fprobe events.
- Some fixes for above features, document and selftests.
- selftests for ftrace (in addition to the new fprobe events):
- Add a test case for multiple consecutive probes in a function
which checks if ftrace based kprobe, optimized kprobe and normal
kprobe can be defined in the same target function.
- Add a test case for optimized probe, which checks whether kprobe
can be optimized or not.

Pull tracing updates from Steven Rostedt:
- Add new feature to have function graph tracer record the return
value. Adds a new option: funcgraph-retval ; when set, will show the
return value of a function in the function graph tracer.
- Also add the option: funcgraph-retval-hex where if it is not set, and
the return value is an error code, then it will return the decimal of
the error code, otherwise it still reports the hex value.
- Add the file /sys/kernel/tracing/osnoise/per_cpu/cpu<cpu>/timerlat_fd
That when a application opens it, it becomes the task that the timer
lat tracer traces. The application can also read this file to find
out how it's being interrupted.
- Add the file /sys/kernel/tracing/available_filter_functions_addrs
that works just the same as available_filter_functions but also shows
the addresses of the functions like kallsyms, except that it gives
the address of where the fentry/mcount jump/nop is. This is used by
BPF to make it easier to attach BPF programs to ftrace hooks.
- Replace strlcpy with strscpy in the tracing boot code.

For pid namespaces, struct pid uses a dynamically sized array member,
"numbers". This was implemented using the ancient 1-element fake
flexible array, which has been deprecated for decades.
Replace it with a C99 flexible array, refactor the array size
calculations to use struct_size(), and address elements via indexes.
Note that the static initializer (which defines a single element) works
as-is, and requires no special handling.
Without this, CONFIG_UBSAN_BOUNDS (and potentially
CONFIG_FORTIFY_SOURCE) will trigger bounds checks:

Fix the STI console to be able to execute either the 64-bit STI ROM code
or the 32-bit STI ROM code.
This is necessary on 64-bit only machines (e.g. C8000 workstation) which
otherwise won't show the STI text console with HP graphic cards like
Visualize-FX5/FX10/FXe.
Note that when calling 32-bit code from a 64-bit kernel one needs to
copy contents on the CPU stack from high memory down below the 4GB
limit.

Pull slab updates from Vlastimil Babka:
- SLAB deprecation:
Following the discussion at LSF/MM 2023 [1] and no objections, the
SLAB allocator is deprecated by renaming the config option (to make
its users notice) to CONFIG_SLAB_DEPRECATED with updated help text.
SLUB should be used instead. Existing defconfigs with CONFIG_SLAB are
also updated.
- SLAB_NO_MERGE kmem_cache flag (Jesper Dangaard Brouer):
There are (very limited) cases where kmem_cache merging is
undesirable, and existing ways to prevent it are hacky. Introduce a
new flag to do that cleanly and convert the existing hacky users.
Btrfs plans to use this for debug kernel builds (that use case is
always fine), networking for performance reasons (that should be very
rare).
- Replace the usage of weak PRNGs (David Keisar Schmidt):
In addition to using stronger RNGs for the security related features,
the code is a bit cleaner.
- Misc code cleanups (SeongJae Parki, Xiongwei Song, Zhen Lei, and
zhaoxinchao)

Pull new ARM SoC support from Arnd Bergmann:
"There are two new SoC families this time, and both appear fairly
similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are
both dual-core Cortex-A35 based chips for the low-power industrial
embedded market, and they mark the first 64-bit product in a widely
used family of 32-bit Arm MCUs and SoCs.
The way into the kernel is completely different here: The team at ST
has a long history of working upstream with their STM32MP1 and other
SoCs, and they produced a complete port to arm64 together with the
initial announcement. Nuvoton also has multiple SoC product lines with
current or previous upstream support, but those are maintained by
third parties and are unrelated. The patch series from Nuvoton's Jacky
Huang had to go through many revisisions to get to this point and is
still missing a few drivers including the serial port for the moment.

Pull ARM SoC devicetree updates from Arnd Bergmann:
"The biggest change this time is for the 32-bit devicetree files, which
are all moved to a new location, using separate subdirectories for
each SoC vendor, following the same scheme that is used on arm64, mips
and riscv. This has been discussed for many years, but so far we never
did this as there was a plan to move the files out of the kernel
entirely, which has never happened.
The impact of this will be that all external patches no longer apply,
and anything depending on the location of the dtb files in the build
directory will have to change. The installed files after 'make
dtbs_install' keep the current location.
There are six added SoCs here that are largely variants of previously
added chips. Two other chips are added in a separate branch along with
their device drivers.
- The Samsung Exynos 4212 makes its return after the Samsung Galaxy
Express phone is addded at last. The SoC support was originally
added in 2012 but removed again in 2017 as it was unused at the
time.
- Amlogic C3 is a Cortex-A35 based smart IP camera chip
- Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of
the still common MSM8916 (Snapdragon 410) phone chip that has been
supported for a long time.
- Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end
laptop chips, used in the Lenovo Flex 5G, which is added along with
the reference board.
- Qualcomm SDX75 is the latest generation modem chip that is used as
a peripherial in phones but can also run a standalone Linux. Unlike
the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55.
- Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the
Xuantie C910 core, a step up from all previously added rv64 chips.
All of the above come with reference board implementations, those
included there are 39 new board files, but only five more 32-bit this
time, probably a new low:
- Marantec Maveo board based on dhcor imx6ull module
- Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip
- Epson Moverio BT-200 AR glasses based on TI OMAP4
- PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM
- ICnova ADB4006 board based on Allwinner A20
On the 64-bit side, there are also fewer addded machines than we had
in the recent releases:
- Three boards based on NXP i.MX8: Emtop SoM & Baseboard, NXP i.MX8MM
EVKB board and i.MX8MP based Gateworks Venice gw7905-2x device.
- NVIDIA IGX Orin and Jetson Orin Nano boards, both based on tegra234
- Qualcomm gains support for 6 reference boards on various members of
their IPQ networking SoC series, as well as the Sony Xperia M4 Aqua
phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board on top
of the various reference platforms for their new chips.
- Rockchips support for several newer boards: Indiedroid Nova
(rk3588), Edgeble Neural Compute Module 6B (rk3588), FriendlyARM
NanoPi R2C Plus (rk3328), Anbernic RG353PS (rk3566), Lunzn
Fastrhino R66S/R68S (rk3568)
- TI K3/AM625 based PHYTEC phyBOARD-Lyra-AM625 board and Toradex
Verdin family with AM62 COM, carrier and dev boards
Other changes to existing boards contain the usual minor improvements
along with
- continued updates to clean up dts files based on dtc warnings and
binding checks, in particular cache properties and node names
- support for devicetree overlays on at91, bcm283x
- significant additions to existing SoC support on mediatek,
qualcomm, ti k3 family, starfive jh71xx, NXP i.MX6 and i.MX8, ST
STM32MP1
As usual, a lot more detail is available in the individual merge

When receiving a scan response there is no way to know if the remote
device is connectable or not, so when it cannot be merged don't
make any assumption and instead just mark it with a new flag defined as
MGMT_DEV_FOUND_SCAN_RSP so userspace can tell it is a standalone
SCAN_RSP.

"We have two new drivers, some improvements to the core code, lots of
different updates to existing GPIO drivers and some dt-bindings on
top.
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.
The single merge pulls in changes that remove all usage of global GPIO
numbers from arch/arm/mach-omap.
Core GPIO library:
- remove unused symbols
- don't spam the kernel log with messages about hogs
- remove old sysfs API cruft
- improve handling of GPIO masks
New drivers:
- add a driver for the BlueField-3 GPIO controller
- add GPIO support for the TPS65219 PMIC
Driver improvements:
- extend the gpio-aggregator driver to support ramp-up/ramp-down
delay
- remove unnecessary CONFIG_OF guards from gpio-aggregator
- readability improvements in gpio-tangier
- switch i2c drivers back to using probe() now that it's been
converted in the i2c subsystem to not taking the id parameter
- remove unused inclusions of of_gpio.h in several drivers
- make pm ops static in gpio-davinci and fix a comment
- use more devres in drivers to shrink and simplify the code
- add missing include in gpio-sa1100
- add HAS_IOPORT KConfig dependency where needed
- add permissions checks before accessing pins in gpio-tegra186
- convert the gpio-zynq driver to using immutable irqchips
- preserve output settings set by the bootloader in gpio-mpc8xxx
Selftests:
- tweak the variable naming in script tests
Device tree updates:
- convert gpio-mmio and gpio-stmpe to YAML
- add parsing of GPIO hogs to gpio-vf610
- add bindings for the Cirrus EP93xx GPIO controller

Pull clk updates from Stephen Boyd:
"This batch of clk driver updates contains almost no new 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

In a future change, the driver will need to determine whether PTP RX
timestamping is enabled on a port (including whether traps were set up
on that port in particular) and that is currently not possible.
The driver supports different RX filters (L2, L4) and kinds of TX
timestamping (one-step, two-step) on its ports, but it saves all
configuration in a single struct hwtstamp_config that is global to the
switch. So, the latest timestamping configuration on one port
(including a request to disable timestamping) affects what gets reported
for all ports, even though the configuration itself is still individual
to each port.
The port timestamping configurations are only coupled because of the
common structure, so replace the hwtstamp_config with a mask of trapped
protocols saved per port. We also have the ptp_cmd to distinguish
between one-step and two-step PTP timestamping, so with those 2 bits of
information we can fully reconstruct a descriptive struct
hwtstamp_config for each port, during the SIOCGHWTSTAMP ioctl.

This modifies our user mode stack expansion code to always take the
mmap_lock for writing before modifying the VM layout.
It's actually something we always technically should have done, but
because we didn't strictly need it, we were being lazy ("opportunistic"
sounds so much better, doesn't it?) about things, and had this hack in
place where we would extend the stack vma in-place without doing the
proper locking.
And it worked fine. We just needed to change vm_start (or, in the case
of grow-up stacks, vm_end) and together with some special ad-hoc locking
using the anon_vma lock and the mm->page_table_lock, it all was fairly
straightforward.
That is, it was all fine until Ruihan Li pointed out that now that the
vma layout uses the maple tree code, we *really* don't just change
vm_start and vm_end any more, and the locking really is broken. Oops.
It's not actually all _that_ horrible to fix this once and for all, and
do proper locking, but it's a bit painful. We have basically three
different cases of stack expansion, and they all work just a bit
differently:
- the common and obvious case is the page fault handling. It's actually
fairly simple and straightforward, except for the fact that we have
something like 24 different versions of it, and you end up in a maze
of twisty little passages, all alike.
- the simplest case is the execve() code that creates a new stack.
There are no real locking concerns because it's all in a private new
VM that hasn't been exposed to anybody, but lockdep still can end up
unhappy if you get it wrong.
- and finally, we have GUP and page pinning, which shouldn't really be
expanding the stack in the first place, but in addition to execve()
we also use it for ptrace(). And debuggers do want to possibly access
memory under the stack pointer and thus need to be able to expand the
stack as a special case.
None of these cases are exactly complicated, but the page fault case in
particular is just repeated slightly differently many many times. And
ia64 in particular has a fairly complicated situation where you can have
both a regular grow-down stack _and_ a special grow-up stack for the
register backing store.
So to make this slightly more manageable, the bulk of this series is to
first create a helper function for the most common page fault case, and
convert all the straightforward architectures to it.
Thus the new 'lock_mm_and_find_vma()' helper function, which ends up
being used by x86, arm, powerpc, mips, riscv, alpha, arc, csky, hexagon,
loongarch, nios2, sh, sparc32, and xtensa. So we not only convert more
than half the architectures, we now have more shared code and avoid some
of those twisty little passages.
And largely due to this common helper function, the full diffstat of
this series ends up deleting more lines than it adds.
That still leaves eight architectures (ia64, m68k, microblaze, openrisc,
parisc, s390, sparc64 and um) that end up doing 'expand_stack()'
manually because they are doing something slightly different from the
normal pattern. Along with the couple of special cases in execve() and
GUP.
So there's a couple of patches that first create 'locked' helper
versions of the stack expansion functions, so that there's a obvious
path forward in the conversion. The execve() case is then actually
pretty simple, and is a nice cleanup from our old "grow-up stackls are
special, because at execve time even they grow down".
The #ifdef CONFIG_STACK_GROWSUP in that code just goes away, because
it's just more straightforward to write out the stack expansion there
manually, instead od having get_user_pages_remote() do it for us in some
situations but not others and have to worry about locking rules for GUP.
And the final step is then to just convert the remaining odd cases to a
new world order where 'expand_stack()' is called with the mmap_lock held
for reading, but where it might drop it and upgrade it to a write, only
to return with it held for reading (in the success case) or with it
completely dropped (in the failure case).
In the process, we remove all the stack expansion from GUP (where
dropping the lock wouldn't be ok without special rules anyway), and add
it in manually to __access_remote_vm() for ptrace().
Thanks to Adrian Glaubitz and Frank Scheiner who tested the ia64 cases.
Everything else here felt pretty straightforward, but the ia64 rules for
stack expansion are really quite odd and very different from everything
else. Also thanks to Vegard Nossum who caught me getting one of those
odd conditions entirely the wrong way around.
Anyway, I think I want to actually move all the stack expansion code to
a whole new file of its own, rather than have it split up between
mm/mmap.c and mm/memory.c, but since this will have to be backported to
the initial maple tree vma introduction anyway, I tried to keep the
patches _fairly_ minimal.
Also, while I don't think it's valid to expand the stack from GUP, the
final patch in here is a "warn if some crazy GUP user wants to try to
expand the stack" patch. That one will be reverted before the final
release, but it's left to catch any odd cases during the merge window
and release candidates.

Pull networking changes from Jakub Kicinski:
"WiFi 7 and sendpage changes are the biggest pieces of work for this
release. The latter will definitely require fixes but I think that we
got it to a reasonable point.
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 sysctl updates from Luis Chamberlain:
"The changes for sysctl are in line with prior efforts to stop usage of
deprecated routines which incur recursion and also make it hard to
remove the empty array element in each sysctl array declaration.
The most difficult user to modify was parport which required a bit of
re-thinking of how to declare shared sysctls there, Joel Granados has
stepped up to the plate to do most of this work and eventual removal
of register_sysctl_table(). That work ended up saving us about 1465
bytes according to bloat-o-meter. Since we gained a few bloat-o-meter
karma points I moved two rather small sysctl arrays from
kernel/sysctl.c leaving us only two more sysctl arrays to move left.
Most changes have been tested on linux-next for about a month. The
last straggler patches are a minor parport fix, changes to the sysctl
kernel selftest so to verify correctness and prevent regressions for
the future change he made to provide an alternative solution for the
special sysctl mount point target which was using the now deprecated
sysctl child element.
This is all prep work to now finally be able to remove the empty array
element in all sysctl declarations / registrations which is expected
to save us a bit of bytes all over the kernel. That work will be
tested early after v6.5-rc1 is out"

Pull module updates from Luis Chamberlain:
"The changes queued up for modules are pretty tame, mostly code removal
of moving of code.
Only two minor functional changes are made, the only one which stands
out is Sebastian Andrzej Siewior's simplification of module reference
counting by removing preempt_disable() and that has been tested on
linux-next for well over a month without no regressions.
I'm now, I guess, also a kitchen sink for some kallsyms changes"
[ There was a mis-communication about the concurrent module load changes
that I had expected to come through Luis despite me authoring the
patch. So some of the module updates were left hanging in the email
ether, and I just committed them separately.
It's my bad - I should have made it more clear that I expected my
own patches to come through the module tree too. Now they missed
linux-next, but hopefully that won't cause any issues - Linus ]
* tag 'v6.5-rc1-modules-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux:
kallsyms: make kallsyms_show_value() as generic function
kallsyms: move kallsyms_show_value() out of kallsyms.c
kallsyms: remove unsed API lookup_symbol_attrs
kallsyms: remove unused arch_get_kallsym() helper
module: Remove preempt_disable() from module reference counting.

Drivers can poll requests directly, so use that. We just need to ensure
the driver's request was allocated from a polled hctx, so a special
driver flag is added to struct io_uring_cmd.
The allows unshared and multipath namespaces to use the same polling
callback, and multipath is guaranteed to get the same queue as the
command was submitted on. Previously multipath polling might check a
different path and poll the wrong info.
The other bonus is we don't need a bio payload in order to poll,
allowing commands like 'flush' and 'write zeroes' to be submitted on the
same high priority queue as read and write commands.
Finally, using the request based polling skips the unnecessary bio
overhead.
