Merge tag 'gpio-v5.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This time very little driver changes but lots of core changes.
We have some interesting cooperative work for ARM and Intel alike,
making the GPIO subsystem more and more suitable for industrial
systems and the like, in addition to the in-kernel users.
We touch driver core (device properties) and lib/* by adding one
simple string array free function, these are authored by Andy
Shevchenko who is a well known and recognized core helpers maintainers
so this should be fine.
We also see some Android GKI-related modularization in the MXC
drivers.
Core changes:
- The big core change is the updated (v2) userspace character device
API.
This corrects badly designed 64-bit alignment around the line
events. We also add the debounce request feature. This echoes the
often quotes passage from Frederick Brooks "The mythical man-month"
to always throw one away, which we have seen before in things such
as V4L2. So we put in a new one and deprecate and obsolete the old
one.
- All example tools in tools/gpio/* are migrated to the new API to
set a good example. The libgpiod userspace library has been
augmented to use this new API pretty much from day 1.
- Some misc API hardening by using strn* function calls has been
added as well.
- Use the simpler IDA interface for GPIO chip instance enumeration.
- Add device core function for counting string arrays in device
properties.
- Provide a generic library function kfree_strarray() that can be
used throughout the kernel.
Driver enhancements:
- The DesignWare dwapb-gpio driver has been enhanced and now uses the
IRQ handling in the gpiolib core.
- The mockup and aggregator drivers have seen some substantial code
clean-up and now use more of the core kernel inftrastructure.
- Misc cleanups using dev_err_probe().
- The MXC drivers (Freescale/NXP) can now be built modularized, which
makes modularized GKI Android kernels happy"

Merge tag 'for-5.10-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"Mostly core updates with a few user visible bits and fixes.
Hilights:
- fsync performance improvements
- less contention of log mutex (throughput +4%, latency -14%,
dbench with 32 clients)
- skip unnecessary commits for link and rename (throughput +6%,
latency -30%, rename latency -75%, dbench with 16 clients)
- make fast fsync wait only for writeback (throughput +10..40%,
runtime -1..-20%, dbench with 1 to 64 clients on various
file/block sizes)
- direct io is now implemented using the iomap infrastructure, that's
the main part, we still have a workaround that requires an iomap
API update, coming in 5.10
- new sysfs exports:
- information about the exclusive filesystem operation status
(balance, device add/remove/replace, ...)
- supported send stream version
Core:
- use ticket space reservations for data, fair policy using the same
infrastructure as metadata
- preparatory work to switch locking from our custom tree locks to
standard rwsem, now the locking context is propagated to all
callers, actual switch is expected to happen in the next dev cycle
- seed device structures are now using list API
- extent tracepoints print proper tree id
- unified range checks for extent buffer helpers
- send: avoid using temporary buffer for copying data
- remove unnecessary RCU protection from space infos
- remove unused readpage callback for metadata, enabling several
cleanups
- replace indirect function calls for end io hooks and remove
extent_io_ops completely
Fixes:
- more lockdep warning fixes
- fix qgroup reservation for delayed inode and an occasional
reservation leak for preallocated files
- fix device replace of a seed device
- fix metadata reservation for fallocate that leads to transaction
aborts
- reschedule if necessary when logging directory items or when
cloning lots of extents
- tree-checker: fix false alert caused by legacy btrfs root item
- send: fix rename/link conflicts for orphanized inodes
- properly initialize device stats for seed devices
- skip devices without magic signature when mounting
Other:
- error handling improvements, BUG_ONs replaced by proper handling,
fuzz fixes
- various function parameter cleanups
- various W=1 cleanups
- error/info messages improved
Mishaps:

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"There's quite a lot of code here, but much of it is due to the
addition of a new PMU driver as well as some arm64-specific selftests
which is an area where we've traditionally been lagging a bit.
In terms of exciting features, this includes support for the Memory
Tagging Extension which narrowly missed 5.9, hopefully allowing
userspace to run with use-after-free detection in production on CPUs
that support it. Work is ongoing to integrate the feature with KASAN
for 5.11.
Another change that I'm excited about (assuming they get the hardware
right) is preparing the ASID allocator for sharing the CPU page-table
with the SMMU. Those changes will also come in via Joerg with the
IOMMU pull.
We do stray outside of our usual directories in a few places, mostly
due to core changes required by MTE. Although much of this has been
Acked, there were a couple of places where we unfortunately didn't get
any review feedback.
Other than that, we ran into a handful of minor conflicts in -next,
but nothing that should post any issues.
Summary:
- Userspace support for the Memory Tagging Extension introduced by
Armv8.5. Kernel support (via KASAN) is likely to follow in 5.11.
- Selftests for MTE, Pointer Authentication and FPSIMD/SVE context
switching.
- Fix and subsequent rewrite of our Spectre mitigations, including
the addition of support for PR_SPEC_DISABLE_NOEXEC.
- Support for the Armv8.3 Pointer Authentication enhancements.
- Support for ASID pinning, which is required when sharing
page-tables with the SMMU.
- MM updates, including treating flush_tlb_fix_spurious_fault() as a
no-op.
- Perf/PMU driver updates, including addition of the ARM CMN PMU
driver and also support to handle CPU PMU IRQs as NMIs.
- Allow prefetchable PCI BARs to be exposed to userspace using normal
non-cacheable mappings.
- Implementation of ARCH_STACKWALK for unwinding.
- Improve reporting of unexpected kernel traps due to BPF JIT
failure.
- Improve robustness of user-visible HWCAP strings and their
corresponding numerical constants.
- Removal of TEXT_OFFSET.
- Removal of some unused functions, parameters and prototypes.
- Removal of MPIDR-based topology detection in favour of firmware
description.
- Cleanups to handling of SVE and FPSIMD register state in
preparation for potential future optimisation of handling across
syscalls.
- Cleanups to the SDEI driver in preparation for support in KVM.
- Miscellaneous cleanups and refactoring work"

rxrpc: Miscellaneous fixes
Here are some miscellaneous rxrpc fixes:
(1) Fix the xdr encoding of the contents read from an rxrpc key.
(2) Fix a BUG() for a unsupported encoding type.
(3) Fix missing _bh lock annotations.
(4) Fix acceptance handling for an incoming call where the incoming call
is encrypted.
(5) The server token keyring isn't network namespaced - it belongs to the
server, so there's no need. Namespacing it means that request_key()
fails to find it.
(6) Fix a leak of the server keyring.

rxrpc: Fix accept on a connection that need securing
When a new incoming call arrives at an userspace rxrpc socket on a new
connection that has a security class set, the code currently pushes it onto
the accept queue to hold a ref on it for the socket. This doesn't work,
however, as recvmsg() pops it off, notices that it's in the SERVER_SECURING
state and discards the ref. This means that the call runs out of refs too
early and the kernel oopses.
By contrast, a kernel rxrpc socket manually pre-charges the incoming call
pool with calls that already have user call IDs assigned, so they are ref'd
by the call tree on the socket.
Change the mode of operation for userspace rxrpc server sockets to work
like this too. Although this is a UAPI change, server sockets aren't
currently functional.

block: scsi_ioctl: Avoid the use of one-element arrays
One-element arrays are being deprecated[1]. Replace the one-element array with a simple object of type compat_caddr_t: 'compat_caddr_t unused'[2], once it seems this field is actually never used. Also, update struct cdrom_generic_command in UAPI by adding an anonimous union to avoid using the one-element array _reserved_.

io_uring: provide IORING_ENTER_SQ_WAIT for SQPOLL SQ ring waits
When using SQPOLL, applications can run into the issue of running out of SQ ring entries because the thread hasn't consumed them yet. The only option for dealing with that is checking later, or busy checking for the condition. Provide IORING_ENTER_SQ_WAIT if applications want to wait on this condition.

io_uring: allow disabling rings during the creation
This patch adds a new IORING_SETUP_R_DISABLED flag to start the rings disabled, allowing the user to register restrictions, buffers, files, before to start processing SQEs. When IORING_SETUP_R_DISABLED is set, SQE are not processed and SQPOLL kthread is not started. The restrictions registration are allowed only when the rings are disable to prevent concurrency issue while processing SQEs. The rings can be enabled using IORING_REGISTER_ENABLE_RINGS opcode with io_uring_register(2).

io_uring: add IOURING_REGISTER_RESTRICTIONS opcode
The new io_uring_register(2) IOURING_REGISTER_RESTRICTIONS opcode permanently installs a feature allowlist on an io_ring_ctx. The io_ring_ctx can then be passed to untrusted code with the knowledge that only operations present in the allowlist can be executed. The allowlist approach ensures that new features added to io_uring do not accidentally become available when an existing application is launched on a newer kernel version. Currently is it possible to restrict sqe opcodes, sqe flags, and register opcodes. IOURING_REGISTER_RESTRICTIONS can only be made once. Afterwards it is not possible to change restrictions anymore. This prevents untrusted code from removing restrictions.

gpio: uapi: define uAPI v2
Add a new version of the uAPI to address existing 32/64-bit alignment issues, add support for debounce and event sequence numbers, allow requested lines with different configurations, and provide some future proofing by adding padding reserved for future use. The alignment issue relates to the gpioevent_data, which packs to different sizes on 32-bit and 64-bit platforms. That creates problems for 32-bit apps running on 64-bit kernels. uAPI v2 addresses that particular issue, and the problem more generally, by adding pad fields that explicitly pad structs out to 64-bit boundaries, so they will pack to the same size now, and even if some of the reserved padding is used for __u64 fields in the future. The new structs have been analysed with pahole to ensure that they are sized as expected and contain no implicit padding. The lack of future proofing in v1 makes it impossible to, for example, add the debounce feature that is included in v2. The future proofing is addressed by providing configurable attributes in line config and reserved padding in all structs for future features. Specifically, the line request, config, info, info_changed and event structs receive updated versions and new ioctls. As the majority of the structs and ioctls were being replaced, it is opportune to rework some of the other aspects of the uAPI: v1 has three different flags fields, each with their own separate bit definitions. In v2 that is collapsed to one - gpio_v2_line_flag. The handle and event requests are merged into a single request, the line request, as the two requests were mostly the same other than the edge detection provided by event requests. As a byproduct, the v2 uAPI allows for multiple lines producing edge events on the same line handle. This is a new capability as v1 only supports a single line in an event request. As a consequence, there are now only two types of file handle to be concerned with, the chip and the line, and it is clearer which ioctls apply to which type of handle. There is also some minor renaming of fields for consistency compared to their v1 counterparts, e.g. offset rather than lineoffset or line_offset, and consumer rather than consumer_label. Additionally, v1 GPIOHANDLES_MAX becomes GPIO_V2_LINES_MAX in v2 for clarity, and the gpiohandle_data __u8 array becomes a bitmap in gpio_v2_line_values. The v2 uAPI is mostly a reorganisation and extension of v1, so userspace code, particularly libgpiod, should readily port to it.

media: v4l2: extend the CSC API to subdevice.
This patch extends the CSC API in video devices to be supported also on sub-devices. The flag V4L2_MBUS_FRAMEFMT_SET_CSC set by the application when calling VIDIOC_SUBDEV_S_FMT ioctl. The flags: V4L2_SUBDEV_MBUS_CODE_CSC_COLORSPACE, V4L2_SUBDEV_MBUS_CODE_CSC_XFER_FUNC, V4L2_SUBDEV_MBUS_CODE_CSC_YCBCR_ENC/V4L2_SUBDEV_MBUS_CODE_CSC_HSV_ENC V4L2_SUBDEV_MBUS_CODE_CSC_QUANTIZATION are set by the driver in the VIDIOC_SUBDEV_ENUM_MBUS_CODE ioctl. New 'flags' fields were added to the structs v4l2_subdev_mbus_code_enum, v4l2_mbus_framefmt which are borrowed from the 'reserved' field The patch also replaces the 'ycbcr_enc' field in 'struct v4l2_mbus_framefmt' with a union that includes 'hsv_enc' Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |
