Pull fwctl subsystem from Jason Gunthorpe:
"fwctl is a new subsystem intended to bring some common rules and order
to the growing pattern of exposing a secure FW interface directly to
userspace.
Unlike existing places like RDMA/DRM/VFIO/uacce that are exposing a
device for datapath operations fwctl is focused on debugging,
configuration and provisioning of the device. It will not have the
necessary features like interrupt delivery to support a datapath.
This concept is similar to the long standing practice in the "HW" RAID
space of having a device specific misc device to manage the RAID
controller FW. fwctl generalizes this notion of a companion debug and
management interface that goes along with a dataplane implemented in
an appropriate subsystem.
There have been three LWN articles written discussing various aspects
of this:
https://lwn.net/Articles/955001/
https://lwn.net/Articles/969383/
https://lwn.net/Articles/990802/
This includes three drivers to launch the subsystem:
- CXL provides a vendor scheme for executing commands and a way to
learn the 'command effects' (ie the security properties) of such
commands. The fwctl driver allows access to these mechanism within
the fwctl security model
- mlx5 is family of networking products, the driver supports all
current Mellanox HW still receiving FW feature updates. This
includes RDMA multiprotocol NICs like ConnectX and the Bluefield
family of Smart NICs.
- AMD/Pensando Distributed Services card is a multi protocol Smart
NIC with a multi PCI function design. fwctl works on the management
PCI function following a 'command effects' model similar to CXL"

io_cmd_buf points to an array of ublksrv_io_desc structs but its type is
char *. Indexing the array requires an explicit multiplication and cast.
The compiler also can't check the pointer types.
Change io_cmd_buf's type to struct ublksrv_io_desc * so it can be
indexed directly and the compiler can type-check the code.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Enable Configuration RRS SV, which makes device readiness visible,
early instead of during child bus scanning (Bjorn Helgaas)
- Log debug messages about reset methods being used (Bjorn Helgaas)
- Avoid reset when it has been disabled via sysfs (Nishanth
Aravamudan)
- Add common pci-ep-bus.yaml schema for exporting several peripherals

several features that require multiple drivers (Herve Codina)
Resource management:
- Enlarge devres table[] to accommodate bridge windows, ROM, IOV
BARs, etc., and validate BAR index in devres interfaces (Philipp
Stanner)
- Fix typo that repeatedly distributed resources to a bridge instead
of iterating over subordinate bridges, which resulted in too little
space to assign some BARs (Kai-Heng Feng)
- Relax bridge window tail sizing for optional resources, e.g., IOV
BARs, to avoid failures when removing and re-adding devices (Ilpo
Järvinen)
- Allow drivers to enable devices even if we haven't assigned
optional IOV resources to them (Ilpo Järvinen)
- Rework handling of optional resources (IOV BARs, ROMs) to reduce
failures if we can't allocate them (Ilpo Järvinen)
- Fix a NULL dereference in the SR-IOV VF creation error path (Shay
Drory)

Power management:
- Allow PCI bridges to go to D3Hot when suspending on all non-x86

Power control:
- Create pwrctrl devices in pci_scan_device() to make it more
symmetric with pci_pwrctrl_unregister() and make pwrctrl devices
for PCI bridges possible (Manivannan Sadhasivam)
- Unregister pwrctrl devices in pci_destroy_dev() so DOE, ASPM, etc.
can still access devices after pci_stop_dev() (Manivannan
Sadhasivam)
- If there's a pwrctrl device for a PCI device, skip scanning it
because the pwrctrl core will rescan the bus after the device is
powered on (Manivannan Sadhasivam)

described via devicetree (Manivannan Sadhasivam)
Bandwidth control:
- Add set_pcie_speed.sh to TEST_PROGS to fix issue when executing the

assign for a bridge secondary bus (Lukas Wunner)
Hotplug:
- Drop superfluous pci_hotplug_slot_list, try_module_get() calls, and

- Drop 'shpchp_debug' module parameter in favor of standard dynamic
debugging (Ilpo Järvinen)
- Drop unused cpcihp .get_power(), .set_power() function pointers

- Disable hotplug interrupts in portdrv only when pciehp is not
enabled to avoid issuing two hotplug commands too close together
(Feng Tang)

to address a deadlock when resuming after a device was removed
during system sleep (Lukas Wunner)

Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

more or less the same algorithms for both system and i/o memory.
The new implementation is more robust, both implementations are now
feature complete (e.g. pixel order reversing now supported by both),
behaves the same way as it uses the identical code for both variants
and adds support for foreign endian framebuffers.
The other patches add some parameter checks, static attribute groups
for sysfs entries and console fixes:

Pass struct request *rq to ublk_cmd_tw_cb() through ublk_uring_cmd_pdu,
mirroring how it works for ublk_cmd_list_tw_cb(). This saves some

Implement ->queue_rqs() for improving perf in case of MQ.
In this way, we just need to call io_uring_cmd_complete_in_task() once for
whole IO batch, then both io_uring and ublk server can get exact batch from
ublk frontend.
Follows IOPS improvement:
- tests
tools/testing/selftests/ublk/kublk add -t null -q 2 [-z]
fio/t/io_uring -p0 /dev/ublkb0
- results:
more than 10% IOPS boost observed
Pass all ublk selftests, especially the io dispatch order test.

IO split is usually bad in io_uring world, since -EAGAIN is caused and
IO handling may have to fallback to io-wq, this way does hurt performance.
ublk starts to support zero copy recently, for avoiding unnecessary IO
split, ublk driver's segment limit should be aligned with backend
device's segment limit.
Another reason is that io_buffer_register_bvec() needs to allocate bvecs,
which number is aligned with ublk request segment number, so that big
memory allocation can be avoided by setting reasonable max_segments limit.
So add segment parameter for providing ublk server chance to align
segment limit with backend, and keep it reasonable from implementation
viewpoint.

Now ublk driver depends on `ubq->canceling` for deciding if the request
can be dispatched via uring_cmd & io_uring_cmd_complete_in_task().
Once ubq->canceling is set, the uring_cmd can be done via ublk_cancel_cmd()
and io_uring_cmd_done().
So set ubq->canceling when queue is frozen, this way makes sure that the
flag can be observed from ublk_queue_rq() reliably, and avoids
use-after-free on uring_cmd.

When using dm-integrity in standalone mode with a keyed hmac algorithm,
integrity tags are calculated and verified internally.
Using plain memcmp to compare the stored and computed tags may leak the
position of the first byte mismatch through side-channel analysis,
allowing to brute-force expected tags in linear time (e.g., by counting
single-stepping interrupts in confidential virtual machine environments).

If execute_location()'s memcpy of do_nothing() gets inlined and unrolled

mov 0x0(%rip),%rax R_X86_64_PC32 .text+0x1374
mov %rax,0x38(%rbx)
mov 0x0(%rip),%rax R_X86_64_PC32 .text+0x136c

Those .text references point to the middle of the function, causing

commit 8a7d12d674ac ("net: usb: usbnet: fix name regression") assumed
that local addresses always came from the kernel, but some devices hand
out local mac addresses so we ended up with point-to-point devices with
a mac set by the driver, renaming to eth%d when they used to be named
usb%d.
Userspace should not rely on device name, but for the sake of stability
restore the local mac address check portion of the naming exception:
point to point devices which either have no mac set by the driver or
have a local mac handed out by the driver will keep the usb%d name.
(some USB LTE modems are known to hand out a stable mac from the locally
administered range; that mac appears to be random (different for
mulitple devices) and can be reset with device-specific commands, so
while such devices would benefit from getting a OUI reserved, we have
to deal with these and might as well preserve the existing behavior
to avoid breaking fragile openwrt configurations and such on upgrade.)

When hw-gro is enabled, the maximum number of header entries that are
needed per wqe (hd_per_wqe) is calculated based on the size of the
reservations among other parameters.
Miscalculation of the size of reservations leads to incorrect
calculation of hd_per_wqe as 0, particularly in the case of large page
size like in aarch64, this prevents the SHAMPO header from being
correctly initialized in the device, ultimately causing the following
cqe err that indicates a violation of PD.

Frag allocators, such as netdev_alloc_frag(), were not designed to
work for fragsz > PAGE_SIZE.
So, switch to page pool for jumbo frames instead of using page frag
allocators. This driver is using page pool for smaller MTUs already.

Calling verity_verify_io in bh for IO of all sizes is not suitable for
embedded devices. From our tests, it can improve the performance of 4K
synchronise random reads.
For example:
./fio --name=rand_read --ioengine=psync --rw=randread --bs=4K \
--direct=1 --numjobs=8 --runtime=60 --time_based --group_reporting \
--filename=/dev/block/mapper/xx-verity
But it will degrade the performance of 512K synchronise sequential reads
on our devices.
For example:
./fio --name=read --ioengine=psync --rw=read --bs=512K --direct=1 \
--numjobs=8 --runtime=60 --time_based --group_reporting \
--filename=/dev/block/mapper/xx-verity
A parameter array is introduced by this change. And users can modify the
default config by /sys/module/dm_verity/parameters/use_bh_bytes.
The default limits for NONE/RT/BE is set to 8192.
The default limits for IDLE is set to 0.
Call verity_verify_io directly when verity_end_io is not in hardirq.

Pull printk updates from Petr Mladek:
- New option "printk.debug_non_panic_cpus" allows to store printk
messages from non-panic CPUs during panic. It might be useful when
panic() fails. It is disabled by default because it increases the
chance to see the messages printed before panic() and on the
panic-CPU.
- New build option "CONFIG_NULL_TTY_DEFAULT_CONSOLE" allows to build
kernel without the virtual terminal support which prefers ttynull
over serial console.
- Do not unblank suspended consoles.
- Some code clean up.

Choices aggregates passed to _aggregate_choices() are already filled
with ones, therefore we can avoid copying a new bitmap on the first
iteration.
This makes setting the PLATFORM_PROFILE_LAST bit on aggregates
unnecessary, so drop it as well.
While at it, add a couple empty lines to improve style.

Depending on the secureboot signature on EFI\BOOT\BOOTX86.EFI the
Lenovo Yoga Tab 3 UEFI will switch its OSID ACPI variable between
1 (Windows) and 4 (Android(GMIN)).
In Windows mode a GPIO event handler gets installed for GPO1 pin 5,
causing Linux' x86-android-tables code which deals with the general
brokenness of this device's ACPI tables to fail to probe with:
[ 17.853705] x86_android_tablets: error -16 getting GPIO INT33FF:01 5
[ 17.859623] x86_android_tablets x86_android_tablets: probe with driver
which renders sound, the touchscreen, charging-management,
battery-monitoring and more non functional.
Add ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS to the existing quirks for this
device to fix this.

Intel Over-Clocking Watchdogs are described in ACPI tables by both the
generic PNP0C02 _CID and their ACPI _HID. The presence of the _CID then
causes the PNP scan handler to attach to the watchdog, preventing the
actual watchdog driver from binding. Address this by adding the ACPI
_HIDs to the list of non-PNP devices, so that the PNP scan handler is
bypassed.
Note that these watchdogs can be described by multiple _HIDs for what
seems to be identical hardware. This commit is not a complete list of
all the possible watchdog ACPI _HIDs.

Driver use devm APIs to manage clk/irq/resources and register the spi
controller, but the legacy remove function will be called first during
device detach and trigger kernel panic. Drop the remove function and use
devm_add_action_or_reset() for driver cleanup to ensure the release
sequence.
