fwctl: Basic ioctl dispatch for the character device
Each file descriptor gets a chunk of per-FD driver specific context that allows the driver to attach a device specific struct to. The core code takes care of the memory lifetime for this structure. The ioctl dispatch and design is based on what was built for iommufd. The ioctls have a struct which has a combined in/out behavior with a typical 'zero pad' scheme for future extension and backwards compatibility. Like iommufd some shared logic does most of the ioctl marshaling and compatibility work and table dispatches to some function pointers for each unique ioctl. This approach has proven to work quite well in the iommufd and rdma subsystems. Allocate an ioctl number space for the subsystem.

blk-crypto: add ioctls to create and prepare hardware-wrapped keys
Until this point, the kernel can use hardware-wrapped keys to do encryption if userspace provides one -- specifically a key in ephemerally-wrapped form. However, no generic way has been provided for userspace to get such a key in the first place. Getting such a key is a two-step process. First, the key needs to be imported from a raw key or generated by the hardware, producing a key in long-term wrapped form. This happens once in the whole lifetime of the key. Second, the long-term wrapped key needs to be converted into ephemerally-wrapped form. This happens each time the key is "unlocked". In Android, these operations are supported in a generic way through KeyMint, a userspace abstraction layer. However, that method is Android-specific and can't be used on other Linux systems, may rely on proprietary libraries, and also misleads people into supporting KeyMint features like rollback resistance that make sense for other KeyMint keys but don't make sense for hardware-wrapped inline encryption keys. Therefore, this patch provides a generic kernel interface for these operations by introducing new block device ioctls: - BLKCRYPTOIMPORTKEY: convert a raw key to long-term wrapped form. - BLKCRYPTOGENERATEKEY: have the hardware generate a new key, then return it in long-term wrapped form. - BLKCRYPTOPREPAREKEY: convert a key from long-term wrapped form to ephemerally-wrapped form. These ioctls are implemented using new operations in blk_crypto_ll_ops.

Driver core and debugfs updates
Here is the big set of driver core and debugfs updates for 6.14-rc1.
It's coming late in the merge cycle as there are a number of merge
conflicts with your tree now, and I wanted to make sure they were
working properly. To resolve them, look in linux-next, and I will send
the "fixup" patch as a response to the pull request.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new
stuff coming in through other trees in this merge window.
There are also a bunch of debugfs updates from Al, and there is at least
one user that does have a regression with these, but Al is working on
tracking down the fix for it. In my use (and everyone else's linux-next
use), it does not seem like a big issue at the moment.
Here's a short list of the things in here:
- driver core bindings for PCI, platform, OF, and some i/o functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing things
in complex ways.
- driver core const work, making more of the api take const * for
different parameters to make the rust bindings easier overall.
- other small fixes and updates
All of these have been in linux-next with all of the aforementioned
merge conflicts, and the one debugfs issue, which looks to be resolved
"soon".

Here is the "big" set of char/misc/iio and other smaller driver
subsystem updates for 6.14-rc1. Loads of different things in here this
development cycle, highlights are:
- ntsync "driver" to handle Windows locking types enabling Wine to
work much better on many workloads (i.e. games). The driver
framework was in 6.13, but now it's enabled and fully working
properly. Should make many SteamOS users happy. Even comes with
tests!
- Large IIO driver updates and bugfixes
- FPGA driver updates
- Coresight driver updates
- MHI driver updates
- PPS driver updatesa
- const bin_attribute reworking for many drivers
- binder driver updates
- smaller driver updates and fixes
All of these have been in linux-next for a while with no reported

security: Add EXEC_RESTRICT_FILE and EXEC_DENY_INTERACTIVE securebits
The new SECBIT_EXEC_RESTRICT_FILE, SECBIT_EXEC_DENY_INTERACTIVE, and their *_LOCKED counterparts are designed to be set by processes setting up an execution environment, such as a user session, a container, or a security sandbox. Unlike other securebits, these ones can be set by unprivileged processes. Like seccomp filters or Landlock domains, the securebits are inherited across processes. When SECBIT_EXEC_RESTRICT_FILE is set, programs interpreting code should control executable resources according to execveat(2) + AT_EXECVE_CHECK (see previous commit). When SECBIT_EXEC_DENY_INTERACTIVE is set, a process should deny execution of user interactive commands (which excludes executable regular files). Being able to configure each of these securebits enables system administrators or owner of image containers to gradually validate the related changes and to identify potential issues (e.g. with interpreter or audit logs). It should be noted that unlike other security bits, the SECBIT_EXEC_RESTRICT_FILE and SECBIT_EXEC_DENY_INTERACTIVE bits are dedicated to user space willing to restrict itself. Because of that, they only make sense in the context of a trusted environment (e.g. sandbox, container, user session, full system) where the process changing its behavior (according to these bits) and all its parent processes are trusted. Otherwise, any parent process could just execute its own malicious code (interpreting a script or not), or even enforce a seccomp filter to mask these bits. Such a secure environment can be achieved with an appropriate access control (e.g. mount's noexec option, file access rights, LSM policy) and an enlighten ld.so checking that libraries are allowed for execution e.g., to protect against illegitimate use of LD_PRELOAD. Ptrace restrictions according to these securebits would not make sense because of the processes' trust assumption. Scripts may need some changes to deal with untrusted data (e.g. stdin, environment variables), but that is outside the scope of the kernel.

exec: Add a new AT_EXECVE_CHECK flag to execveat(2)
Add a new AT_EXECVE_CHECK flag to execveat(2) to check if a file would
be allowed for execution. The main use case is for script interpreters
and dynamic linkers to check execution permission according to the
kernel's security policy. Another use case is to add context to access
logs e.g., which script (instead of interpreter) accessed a file. As
any executable code, scripts could also use this check [1].
This is different from faccessat(2) + X_OK which only checks a subset of
access rights (i.e. inode permission and mount options for regular
files), but not the full context (e.g. all LSM access checks). The main
use case for access(2) is for SUID processes to (partially) check access
on behalf of their caller. The main use case for execveat(2) +
AT_EXECVE_CHECK is to check if a script execution would be allowed,
according to all the different restrictions in place. Because the use
of AT_EXECVE_CHECK follows the exact kernel semantic as for a real
execution, user space gets the same error codes.
An interesting point of using execveat(2) instead of openat2(2) is that
it decouples the check from the enforcement. Indeed, the security check
can be logged (e.g. with audit) without blocking an execution
environment not yet ready to enforce a strict security policy.
LSMs can control or log execution requests with
security_bprm_creds_for_exec(). However, to enforce a consistent and
complete access control (e.g. on binary's dependencies) LSMs should
restrict file executability, or measure executed files, with
security_file_open() by checking file->f_flags & __FMODE_EXEC.
Because AT_EXECVE_CHECK is dedicated to user space interpreters, it
doesn't make sense for the kernel to parse the checked files, look for
interpreters known to the kernel (e.g. ELF, shebang), and return ENOEXEC
if the format is unknown. Because of that, security_bprm_check() is
never called when AT_EXECVE_CHECK is used.
It should be noted that script interpreters cannot directly use
execveat(2) (without this new AT_EXECVE_CHECK flag) because this could
lead to unexpected behaviors e.g., `python script.sh` could lead to Bash
being executed to interpret the script. Unlike the kernel, script
interpreters may just interpret the shebang as a simple comment, which
should not change for backward compatibility reasons.
Because scripts or libraries files might not currently have the
executable permission set, or because we might want specific users to be
allowed to run arbitrary scripts, the following patch provides a dynamic
configuration mechanism with the SECBIT_EXEC_RESTRICT_FILE and
SECBIT_EXEC_DENY_INTERACTIVE securebits.
This is a redesign of the CLIP OS 4's O_MAYEXEC:

iommufd 6.13 merge window pull
Several new features and uAPI for iommufd:
- IOMMU_IOAS_MAP_FILE allows passing in a file descriptor as the backing
memory for an iommu mapping. To date VFIO/iommufd have used VMA's and
pin_user_pages(), this now allows using memfds and memfd_pin_folios().
Notably this creates a pure folio path from the memfd to the iommu page
table where memory is never broken down to PAGE_SIZE.
- IOMMU_IOAS_CHANGE_PROCESS moves the pinned page accounting between two
processes. Combined with the above this allows iommufd to support a VMM
re-start using exec() where something like qemu would exec() a new
version of itself and fd pass the memfds/iommufd/etc to the new
process. The memfd allows DMA access to the memory to continue while
the new process is getting setup, and the CHANGE_PROCESS updates all
the accounting.
- Support for fault reporting to userspace on non-PRI HW, such as ARM
stall-mode embedded devices.
- IOMMU_VIOMMU_ALLOC introduces the concept of a HW/driver backed virtual
iommu. This will be used by VMMs to access hardware features that are
contained with in a VM. The first use is to inform the kernel of the
virtual SID to physical SID mapping when issuing SID based invalidation
on ARM. Further uses will tie HW features that are directly accessed by
the VM, such as invalidation queue assignment and others.
- IOMMU_VDEVICE_ALLOC informs the kernel about the mapping of virtual
device to physical device within a VIOMMU. Minimially this is used to
translate VM issued cache invalidation commands from virtual to physical
device IDs.
- Enhancements to IOMMU_HWPT_INVALIDATE and IOMMU_HWPT_ALLOC to work with
the VIOMMU
- ARM SMMuv3 support for nested translation. Using the VIOMMU and VDEVICE
the driver can model this HW's behavior for nested translation. This
includes a shared branch from Will.

media: uapi: videodev2: Add V4L2_META_FMT_RK_ISP1_EXT_PARAMS
The rkisp1 driver stores ISP configuration parameters in the fixed rkisp1_params_cfg structure. As the members of the structure are part of the userspace API, the structure layout is immutable and cannot be extended further. Introducing new parameters or modifying the existing ones would change the buffer layout and cause breakages in existing applications. The allow for future extensions to the ISP parameters, introduce a new extensible parameters format, with a new format 4CC. Document usage of the new format in the rkisp1 admin guide.

media: cec: core: add new CEC_MSG_FL_REPLY_VENDOR_ID flag
If this flag is set, then the reply is expected to consist of the CEC_MSG_VENDOR_COMMAND_WITH_ID opcode followed by the Vendor ID (as used in bytes 1-4 of the message), followed by the struct cec_msg reply field. Note that this assumes that the byte after the Vendor ID is a vendor-specific opcode. This flag makes it easier to wait for replies to vendor commands, using the same CEC framework support for waiting for regular replies. Support for this flag is indicated by setting the new CEC_CAP_REPLY_VENDOR_ID capability.

Nothing hugely exciting happening in the documentation tree this time
around, mostly more of the usual:
- More Spanish, Italian, and Chinese translations
- A new script, scripts/checktransupdate.py, can be used to see which
commits have touched an (English) document since a given translation was
last updated.
- A couple of "best practices" suggestions (on Link: tags and off-list
discussions) that were not entirely at consensus level, but I concluded
they were close enough to accept.
- Some nice cleanups removing documentation for kernel parameters that have
not been recognized for ... a long time.
...along with the usual updates, typo fixes, and such.

misc: mrvl-cn10k-dpi: add Octeon CN10K DPI administrative driver
Adds a misc driver for Marvell CN10K DPI(DMA Engine) device's physical function which initializes DPI DMA hardware's global configuration and enables hardware mailbox channels between physical function (PF) and it's virtual functions (VF). VF device drivers (User space drivers) use this hw mailbox to communicate any required device configuration on it's respective VF device. Accordingly, this DPI PF driver provisions the VF device resources. At the hardware level, the DPI physical function (PF) acts as a management interface to setup the VF device resources, VF devices are only provisioned to handle or control the actual DMA Engine's data transfer capabilities.

mm/memfd: add documentation for MFD_NOEXEC_SEAL MFD_EXEC
When MFD_NOEXEC_SEAL was introduced, there was one big mistake: it didn't have proper documentation. This led to a lot of confusion, especially about whether or not memfd created with the MFD_NOEXEC_SEAL flag is sealable. Before MFD_NOEXEC_SEAL, memfd had to explicitly set MFD_ALLOW_SEALING to be sealable, so it's a fair question. As one might have noticed, unlike other flags in memfd_create, MFD_NOEXEC_SEAL is actually a combination of multiple flags. The idea is to make it easier to use memfd in the most common way, which is NOEXEC + F_SEAL_EXEC + MFD_ALLOW_SEALING. This works with sysctl vm.noexec to help existing applications move to a more secure way of using memfd. Proposals have been made to put MFD_NOEXEC_SEAL non-sealable, unless MFD_ALLOW_SEALING is set, to be consistent with other flags [1], Those are based on the viewpoint that each flag is an atomic unit, which is a reasonable assumption. However, MFD_NOEXEC_SEAL was designed with the intent of promoting the most secure method of using memfd, therefore a combination of multiple functionalities into one bit. Furthermore, the MFD_NOEXEC_SEAL has been added for more than one year, and multiple applications and distributions have backported and utilized it. Altering ABI now presents a degree of risk and may lead to disruption. MFD_NOEXEC_SEAL is a new flag, and applications must change their code to use it. There is no backward compatibility problem. When sysctl vm.noexec == 1 or 2, applications that don't set MFD_NOEXEC_SEAL or MFD_EXEC will get MFD_NOEXEC_SEAL memfd. And old-application might break, that is by-design, in such a system vm.noexec = 0 shall be used. Also no backward compatibility problem. I propose to include this documentation patch to assist in clarifying the semantics of MFD_NOEXEC_SEAL, thereby preventing any potential future confusion. Finally, I would like to express my gratitude to David Rheinsberg and Barnabás Pőcze for initiating the discussion on the topic of sealability.

docs: gpio: prefer pread(2) for interrupt reading
In legacy sysfs GPIO, when using poll(2) on the sysfs GPIO value for state change awaiting, a subsequent read(2) is required for consuming the event, which the doc recommends the use of lseek(2) or close-and-reopen to reset the file offset afterwards. The recommendations however, require at least 2 syscalls to consume the event. Gladly, use of pread(2) require only 1 syscall for the consumption. Let's advertise this usage by prioritizing its placement.

Networking changes for 6.10.
Core & protocols
----------------
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd passing
functionality. New method based on Tarjan's Strongly Connected Components
algorithm should be both faster and remove a lot of workarounds
we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP packets
and forwarding them together. Useful for small switches / routers which
lack basic checksum offload in some scenarios (e.g. PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't
use NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory accounting,
RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked,
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states.
State can be used either for input or output packet processing.
Things we sprinkled into general kernel code
--------------------------------------------
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter
---------
- Use GFP_KERNEL to clone elements, to deal better with OOM situations
and avoid failures in the .commit step.
BPF
---
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function entry
and return, the entry program can decide if the return program gets
executed and the entry program can share u64 cookie value with return
program. "Session mode" is a common use-case for tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw tracepoint
programs in order to ease migration from classic to raw tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V JITs.
This allows inlining functions which need to access per-CPU state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86 instruction.
Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor process-context
bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API
----------
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line) config.
- Initial bits of a queue control API, for now allowing a single queue
to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling
-----------------
- Remove the need to create a config file to run the net forwarding tests
so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test machine).
Add a few such tests.
- Create a shared code library for writing Python tests. Expose the YAML
Netlink library from tools/ to the tests for easy Netlink access.
- Move netfilter tests under net/, extend them, separate performance tests
from correctness tests, and iron out issues found by running them
"on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF info,
TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers
-------
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application rather
than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):

media: v4l: subdev: Add len_routes field to struct v4l2_subdev_routing
The len_routes field is used to tell the size of the routes array in struct v4l2_subdev_routing. This way the number of routes returned from S_ROUTING IOCTL may be larger than the number of routes provided, in case there are more routes returned by the driver. Note that this uAPI is still disabled in the code, so this change can safely be done. Anyone who manually patched the code to enable this uAPI must update their code. The patch also increases the number of reserved fields in struct v4l2_subdev_routing.

media: v4l: Support line-based metadata capture
Many camera sensors, among other devices, transmit embedded data and image data for each CSI-2 frame. This embedded data typically contains register configuration of the sensor that has been used to capture the image data of the same frame. The embedded data is received by the CSI-2 receiver and has the same properties as the image data, including that it is line based: it has width, height and bytesperline (stride). Add these fields to struct v4l2_meta_format and document them. Also add V4L2_FMT_FLAG_META_LINE_BASED to tell a given format is line-based i.e. these fields of struct v4l2_meta_format are valid for it.

media: uapi: v4l: Add generic 8-bit metadata format definitions
Generic 8-bit metadata formats define the in-memory data layout but not the format of the data itself. The reasoning for having such formats is to allow CSI-2 receiver drivers to receive and DMA drivers to write the data to memory without knowing a large number of device-specific formats. These formats may be used only in conjunction with a Media Controller pipeline where the internal pad of the source sub-device defines the specific format of the data (using an mbus code).

media: uapi: Add generic serial metadata mbus formats
Add generic serial metadata mbus formats. These formats describe data width and packing but not the content itself. The reason for specifying such formats is that the formats as such are fairly device specific but they are still handled by CSI-2 receiver drivers that should not be aware of device specific formats. What makes generic metadata formats possible is that these formats are parsed by software only, after capturing the data to system memory. Also add a definition for "Data Unit" to cover what is essentially a pixel but is not image data.

ntsync: Introduce NTSYNC_IOC_CREATE_SEM.
This corresponds to the NT syscall NtCreateSemaphore(). Semaphores are one of three types of object to be implemented in this driver, the others being mutexes and events. An NT semaphore contains a 32-bit counter, and is signaled and can be acquired when the counter is nonzero. The counter has a maximum value which is specified at creation time. The initial value of the semaphore is also specified at creation time. There are no restrictions on the maximum and initial value. Each object is exposed as an file, to which any number of fds may be opened. When all fds are closed, the object is deleted. Objects hold a pointer to the ntsync_device that created them. The device's reference count is driven by struct file.

gpio updates for v6.9
Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to GPIO device
structs themselves and to GPIO descriptors
- make the GPIO subsystem resilient to the GPIO providers being unbound while
the API calls are in progress
- don't dereference the SRCU-protected chip pointer if the information we need
can be obtained from the GPIO device structure
- move some of the information contained in struct gpio_chip to struct
gpio_device to further reduce the need to dereference the former
- pass the GPIO device struct instead of the GPIO chip to sysfs callback to,
again, reduce the need for accessing the latter
- get GPIO descriptors from the GPIO device, not from the chip for the same
reason
- allow for mostly lockless operation of the GPIO driver API: assure
consistency with SRCU and atomic operations
- remove the global GPIO spinlock
- remove the character device RW semaphore
Core GPIOLIB:
- constify pointers in GPIO API where applicable
- unify the GPIO counting APIs for ACPI and OF
- provide a macro for iterating over all GPIOs, not only the ones that are
requested
- remove leftover typedefs
- pass the consumer device to GPIO core in devm_fwnode_gpiod_get_index() for
improved logging
- constify the GPIO bus type
- don't warn about removing GPIO chips with descriptors still held by users as
we can now handle this situation gracefully
- remove unused logging helpers
- unexport functions that are only used internally in the GPIO subsystem
- set the device type (assign the relevant struct device_type) for GPIO devices
New drivers:
- add the ChromeOS EC GPIO driver
Driver improvements:
- allow building gpio-vf610 with COMPILE_TEST as well as disabling it in
menuconfig (before it was always built for i.MX cofigs)
- count the number of EICs using the device properties instead of hard-coding
it in gpio-eic-sprd
- improve the device naming, extend the debugfs output and add lockdep asserts
to gpio-sim
DT bindings:
- document the 'label' property for gpio-pca9570
- convert aspeed,ast2400-gpio bindings to DT schema
- disallow unevaluated properties for gpio-mvebu
- document a new model in renesas,rcar-gpio
Documentation:
- improve the character device kerneldocs in user-space headers
- add proper documentation for the character device uAPI (both v1 and v2)
- move the sysfs and gpio-mockup docs into the "obsolete" section
- improve naming consistency for GPIO terms
- clarify the line values description for sysfs
- minor docs improvements
- improve the driver API contract for setting GPIO direction
- mark unsafe APIs as deprecated in kerneldocs and suggest replacements
Other:
- remove an obsolete test from selftests

Merge tag 'gpio-updates-for-v6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"The biggest feature is the locking overhaul. Up until now the
synchronization in the GPIO subsystem was broken. There was a single
spinlock "protecting" multiple data structures but doing it wrong (as
evidenced by several places where it would be released when a sleeping
function was called and then reacquired without checking the protected
state).
We tried to use an RW semaphore before but the main issue with GPIO is
that we have drivers implementing the interfaces in both sleeping and
non-sleeping ways as well as user-facing interfaces that can be called
both from process as well as atomic contexts. Both ends converge in
the same code paths that can use neither spinlocks nor mutexes. The
only reasonable way out is to use SRCU and go mostly lockless. To that
end: we add several SRCU structs in relevant places and use them to
assure consistency between API calls together with atomic reads and
writes of GPIO descriptor flags where it makes sense.
This code has spent several weeks in next and has received several
fixes in the first week or two after which it stabilized nicely. The
GPIO subsystem is now resilient to providers being suddenly unbound.
We managed to also remove the existing character device RW semaphore
and the obsolete global spinlock.
Other than the locking rework we have one new driver (for Chromebook
EC), much appreciated documentation improvements from Kent and the
regular driver improvements, DT-bindings updates and GPIOLIB core
tweaks.
Serialization rework:
- use SRCU to serialize access to the global GPIO device list, to
GPIO device structs themselves and to GPIO descriptors
- make the GPIO subsystem resilient to the GPIO providers being
unbound while the API calls are in progress
- don't dereference the SRCU-protected chip pointer if the
information we need can be obtained from the GPIO device structure
- move some of the information contained in struct gpio_chip to
struct gpio_device to further reduce the need to dereference the
former
- pass the GPIO device struct instead of the GPIO chip to sysfs
callback to, again, reduce the need for accessing the latter
- get GPIO descriptors from the GPIO device, not from the chip for
the same reason
- allow for mostly lockless operation of the GPIO driver API: assure
consistency with SRCU and atomic operations
- remove the global GPIO spinlock
- remove the character device RW semaphore
Core GPIOLIB:
- constify pointers in GPIO API where applicable
- unify the GPIO counting APIs for ACPI and OF
- provide a macro for iterating over all GPIOs, not only the ones
that are requested
- remove leftover typedefs
- pass the consumer device to GPIO core in
devm_fwnode_gpiod_get_index() for improved logging
- constify the GPIO bus type
- don't warn about removing GPIO chips with descriptors still held by
users as we can now handle this situation gracefully
- remove unused logging helpers
- unexport functions that are only used internally in the GPIO
subsystem
- set the device type (assign the relevant struct device_type) for
GPIO devices
New drivers:
- add the ChromeOS EC GPIO driver
Driver improvements:
- allow building gpio-vf610 with COMPILE_TEST as well as disabling it
in menuconfig (before it was always built for i.MX cofigs)
- count the number of EICs using the device properties instead of
hard-coding it in gpio-eic-sprd
- improve the device naming, extend the debugfs output and add
lockdep asserts to gpio-sim
DT bindings:
- document the 'label' property for gpio-pca9570
- convert aspeed,ast2400-gpio bindings to DT schema
- disallow unevaluated properties for gpio-mvebu
- document a new model in renesas,rcar-gpio
Documentation:
- improve the character device kerneldocs in user-space headers
- add proper documentation for the character device uAPI (both v1 and v2)
- move the sysfs and gpio-mockup docs into the "obsolete" section
- improve naming consistency for GPIO terms
- clarify the line values description for sysfs
- minor docs improvements
- improve the driver API contract for setting GPIO direction
- mark unsafe APIs as deprecated in kerneldocs and suggest
replacements
Other:
- remove an obsolete test from selftests"

Networking changes for 6.9.
Core & protocols
----------------
- Large effort by Eric to lower rtnl_lock pressure and remove locks:
- Make commonly used parts of rtnetlink (address, route dumps etc.)
lockless, protected by RCU instead of rtnl_lock.
- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core
instead of once for each driver / callback.
- Remove locks / serialization in the socket diag interface.
- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
- Remove the dev_base_lock, depend on RCU where necessary.
- Support busy polling on a per-epoll context basis. Poll length
and budget parameters can be set independently of system defaults.
- Introduce struct net_hotdata, to make sure read-mostly global config
variables fit in as few cache lines as possible.
- Add optional per-nexthop statistics to ease monitoring / debug
of ECMP imbalance problems.
- Support TCP_NOTSENT_LOWAT in MPTCP.
- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.
- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.
- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.
- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.
- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for
use on fastpaths).
- Speed up scanning for expired routes by keeping a dedicated list.
- Speed up "generic" XDP by trying harder to avoid large allocations.
- Support attaching arbitrary metadata to netconsole messages.
Things we sprinkled into general kernel code
--------------------------------------------
- Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce
VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena).
- Rework selftest harness to enable the use of the full range of
ksft exit code (pass, fail, skip, xfail, xpass).
Netfilter
---------
- Allow userspace to define a table that is exclusively owned by a daemon
(via netlink socket aliveness) without auto-removing this table when
the userspace program exits. Such table gets marked as orphaned and
a restarting management daemon can re-attach/regain ownership.
- Speed up element insertions to nftables' concatenated-ranges set type.
Compact a few related data structures.
BPF
---
- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.
- Introduce bpf_arena which is sparse shared memory region between BPF
program and user space where structures inside the arena can have
pointers to other areas of the arena, and pointers work seamlessly
for both user-space programs and BPF programs.
- Introduce may_goto instruction that is a contract between the verifier
and the program. The verifier allows the program to loop assuming it's
behaving well, but reserves the right to terminate it.
- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.
- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops type.
- Add support for retrieval of cookies for perf/kprobe multi links.
- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF firewalls.
- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF objects.
Wireless
--------
- Add SPP (signaling and payload protected) AMSDU support.
- Support wider bandwidth OFDMA, as required for EHT operation.
Driver API
----------
- Major overhaul of the Energy Efficient Ethernet internals to support
new link modes (2.5GE, 5GE), share more code between drivers
(especially those using phylib), and encourage more uniform behavior.
Convert and clean up drivers.
- Define an API for querying per netdev queue statistics from drivers.
- IPSec: account in global stats for fully offloaded sessions.
- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.
- Enable Rx hashing (RSS) on GTP protocol fields.
Misc
----
- Improvements and refactoring all over networking selftests.
- Create uniform module aliases for TC classifiers, actions,
and packet schedulers to simplify creating modprobe policies.
- Address all missing MODULE_DESCRIPTION() warnings in networking.
- Extend the Netlink descriptions in YAML to cover message encapsulation
or "Netlink polymorphism", where interpretation of nested attributes
depends on link type, classifier type or some other "class type".

Add an ioctl for getting and setting epoll_params. User programs can use
this ioctl to get and set the busy poll usec time, packet budget, and
prefer busy poll params for a specific epoll context.
Parameters are limited:
- busy_poll_usecs is limited to <= s32_max
- busy_poll_budget is limited to <= NAPI_POLL_WEIGHT by unprivileged
users (!capable(CAP_NET_ADMIN))

fs: FS_IOC_GETUUID
Add a new generic ioctls for querying the filesystem UUID. These are lifted versions of the ext4 ioctls, with one change: we're not using a flexible array member, because UUIDs will never be more than 16 bytes. This patch adds a generic implementation of FS_IOC_GETFSUUID, which reads from super_block->s_uuid. We're not lifting SETFSUUID from ext4 - that can be done on offline filesystems by the people who need it, trying to do it online is just asking for too much trouble.

media: mc: Expand MUST_CONNECT flag to always require an enabled link
The MEDIA_PAD_FL_MUST_CONNECT flag indicates that the pad requires an enabled link to stream, but only if it has any link at all. This makes little sense, as if a pad is part of a pipeline, there are very few use cases for an active link to be mandatory only if links exist at all. A review of in-tree drivers confirms they all need an enabled link for pads marked with the MEDIA_PAD_FL_MUST_CONNECT flag. Expand the scope of the flag by rejecting pads that have no links at all. This requires modifying the pipeline build code to add those pads to the pipeline.

Documentation: userspace-api: Document perf ring buffer mechanism
In the Linux perf tool, the ring buffer serves not only as a medium for transferring PMU event data but also as a vital mechanism for hardware tracing using technologies like Intel PT and Arm CoreSight, etc. Consequently, the ring buffer mechanism plays a crucial role by ensuring high throughput for data transfer between the kernel and user space while avoiding excessive overhead caused by the ring buffer itself. This commit documents the ring buffer mechanism in detail. It explains the implementation of both the regular ring buffer and the AUX ring buffer. Additionally, it covers how these ring buffers support various tracing modes and explains the synchronization with memory barriers.

fbdev/intelfb: Remove driver
From looking at the PCI IDs, every device supported by intelfb is also supported by i915. Anyone still using intelfb should please move on to i915, which does everything intelfb does but better. Removing intelfb is motivated by the driver's excessive use of the global screen_info state. The state belongs to architecture and firmware code; device drivers should not attempt to access it. But fixing intelfb would require a significant change in the driver's probing logic. As intelfb has been obsolete for nearly 2 decades, it is probably not worth the effort. Let's just remove it. Also remove the related documentation. Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maik Broemme <mbroemme@libmpq.org> Signed-off-by: Helge Deller <deller@gmx.de> |

- Various kernel-doc tweaks to, for example, make it deal properly with

Networking changes for 6.8.
Core & protocols
----------------
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up
build time warnings to safeguard against future header changes.
This improves TCP performances with many concurrent connections
up to 40%.
- Add page-pool netlink-based introspection, exposing the
memory usage and recycling stats. This helps indentify
bad PP users and possible leaks.
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set.
This lowers the time taken by connect() for hosts having
many active connections to the same destination.
- Refactor the TCP bind conflict code, shrinking related socket
structs.
- Refactor TCP SYN-Cookie handling, as a preparation step to
allow arbitrary SYN-Cookie processing via eBPF.
- Tune optmem_max for 0-copy usage, increasing the default value
to 128KB and namespecifying it.
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations.
- Reduce extension header parsing overhead at GRO time.
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries.
- Reorder nftables struct members, to keep data accessed by the
datapath first.
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer.
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex).
- More data-race annotations.
- Extend the diag interface to dump TCP bound-only sockets.
- Conditional notification of events for TC qdisc class and actions.
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID.
- Implement SMCv2.1 virtual ISM device support.
- Add support for Batman-avd mulicast packet type.
BPF
---
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers. It
improves the verifier "instructions processed" metric from single
digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload.
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y.
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques.

Merge tag 'net-next-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"The most interesting thing is probably the networking structs
reorganization and a significant amount of changes is around
self-tests.
Core & protocols:
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up build
time warnings to safeguard against future header changes
This improves TCP performances with many concurrent connections up
to 40%
- Add page-pool netlink-based introspection, exposing the memory
usage and recycling stats. This helps indentify bad PP users and
possible leaks
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
lowers the time taken by connect() for hosts having many active
connections to the same destination
- Refactor the TCP bind conflict code, shrinking related socket
structs
- Refactor TCP SYN-Cookie handling, as a preparation step to allow
arbitrary SYN-Cookie processing via eBPF
- Tune optmem_max for 0-copy usage, increasing the default value to
128KB and namespecifying it
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations
- Reduce extension header parsing overhead at GRO time
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries
- Reorder nftables struct members, to keep data accessed by the
datapath first
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex)
- More data-race annotations
- Extend the diag interface to dump TCP bound-only sockets
- Conditional notification of events for TC qdisc class and actions
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID
- Implement SMCv2.1 virtual ISM device support
- Add support for Batman-avd mulicast packet type
BPF:
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers.
This improves the verifier "instructions processed" metric from
single digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer
experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques
- Support uid/gid options when mounting bpffs
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is
identified by its id
- Extend verifier to allow bpf_refcount_acquire() of a map value
field obtained via direct load which is a use-case needed in
sched_ext
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter

The first syscall simply lists the LSMs enabled, while the second and third get and set the current process' LSM attributes. Yes, these syscalls may provide similar functionality to what can be found under /proc or /sys, but they were designed to support multiple, simultaneaous (stacked) LSMs from the start as opposed to the current /proc based solutions which were created at a time when only one LSM was allowed to be active at a given time. We have spent considerable time discussing ways to extend the existing /proc interfaces to support multiple, simultaneaous LSMs and even our best ideas have been far too ugly to support as a kernel API; after +20 years in the kernel, I felt the LSM layer had established itself enough to justify a handful of syscalls. Support amongst the individual LSM developers has been nearly unanimous, with a single objection coming from Tetsuo (TOMOYO) as he is worried that the LSM_ID_XXX token concept will make it more difficult for out-of-tree LSMs to survive. Several members of the LSM community have demonstrated the ability for out-of-tree LSMs to continue to exist by picking high/unused LSM_ID values as well as pointing out that many kernel APIs rely on integer identifiers, e.g. syscalls (!), but unfortunately Tetsuo's objections remain. My personal opinion is that while I have no interest in penalizing out-of-tree LSMs, I'm not going to penalize in-tree development to support out-of-tree development, and I view this as a necessary step forward to support the push for expanded LSM stacking and reduce our reliance on /proc and /sys which has occassionally been problematic for some container users. Finally, we have included the linux-api folks on (all?) recent revisions of the patchset and addressed all of their concerns. - Add a new security_file_ioctl_compat() LSM hook to handle the 32-bit ioctls on 64-bit systems problem. This patch includes support for all of the existing LSMs which provide ioctl hooks, although it turns out only SELinux actually cares about the individual ioctls. It is worth noting that while Casey (Smack) and Tetsuo (TOMOYO) did not give explicit ACKs to this patch, they did both indicate they are okay with the changes. - Fix a potential memory leak in the CALIPSO code when IPv6 is disabled at boot. While it's good that we are fixing this, I doubt this is something users are seeing in the wild as you need to both disable IPv6 and then attempt to configure IPv6 labeled networking via NetLabel/CALIPSO; that just doesn't make much sense. Normally this would go through netdev, but Jakub asked me to take this patch and of all the trees I maintain, the LSM tree seemed like the best fit. - Update the LSM MAINTAINERS entry with additional information about our process docs, patchwork, bug reporting, etc. I also noticed that the Lockdown LSM is missing a dedicated MAINTAINERS entry so I've added that to the pull request. I've been working with one of the major Lockdown authors/contributors to see if they are willing to step up and assume a Lockdown maintainer role; hopefully that will happen soon, but in the meantime I'll continue to look after it. - Add a handful of mailmap entries for Serge Hallyn and myself. * tag 'lsm-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (27 commits) lsm: new security_file_ioctl_compat() hook lsm: Add a __counted_by() annotation to lsm_ctx.ctx calipso: fix memory leak in netlbl_calipso_add_pass() selftests: remove the LSM_ID_IMA check in lsm/lsm_list_modules_test MAINTAINERS: add an entry for the lockdown LSM MAINTAINERS: update the LSM entry mailmap: add entries for Serge Hallyn's dead accounts mailmap: update/replace my old email addresses lsm: mark the lsm_id variables are marked as static lsm: convert security_setselfattr() to use memdup_user() lsm: align based on pointer length in lsm_fill_user_ctx() lsm: consolidate buffer size handling into lsm_fill_user_ctx() lsm: correct error codes in security_getselfattr() lsm: cleanup the size counters in security_getselfattr() lsm: don't yet account for IMA in LSM_CONFIG_COUNT calculation lsm: drop LSM_ID_IMA LSM: selftests for Linux Security Module syscalls SELinux: Add selfattr hooks AppArmor: Add selfattr hooks Smack: implement setselfattr and getselfattr hooks ... |

media: v4l2-subdev: Add which field to struct v4l2_subdev_frame_interval
Due to a historical mishap, the v4l2_subdev_frame_interval structure is the only part of the V4L2 subdev userspace API that doesn't contain a 'which' field. This prevents trying frame intervals using the subdev 'TRY' state mechanism. Adding a 'which' field is simple as the structure has 8 reserved fields. This would however break userspace as the field is currently set to 0, corresponding to V4L2_SUBDEV_FORMAT_TRY, while the corresponding ioctls currently operate on the 'ACTIVE' state. We thus need to add a new subdev client cap, V4L2_SUBDEV_CLIENT_CAP_INTERVAL_USES_WHICH, to indicate that userspace is aware of this new field.

powerpc/pseries/papr-sysparm: Expose character device to user space
Until now the papr_sysparm APIs have been kernel-internal. But user space needs access to PAPR system parameters too. The only method available to user space today to get or set system parameters is using sys_rtas() and /dev/mem to pass RTAS-addressable buffers between user space and firmware. This is incompatible with lockdown and should be deprecated. So provide an alternative ABI to user space in the form of a /dev/papr-sysparm character device with just two ioctl commands (get and set). The data payloads involved are small enough to fit in the ioctl argument buffer, making the code relatively simple. Exposing the system parameters through sysfs has been considered but it would be too awkward: * The kernel currently does not have to contain an exhaustive list of defined system parameters. This is a convenient property to maintain because we don't have to update the kernel whenever a new parameter is added to PAPR. Exporting a named attribute in sysfs for each parameter would negate this. * Some system parameters are text-based and some are not. * Retrieval of at least one system parameter requires input data, which a simple read-oriented interface can't support.

powerpc/pseries: Add papr-vpd character driver for VPD retrieval
PowerVM LPARs may retrieve Vital Product Data (VPD) for system
components using the ibm,get-vpd RTAS function.
We can expose this to user space with a /dev/papr-vpd character
device, where the programming model is:
struct papr_location_code plc = { .str = "", }; /* obtain all VPD */
int devfd = open("/dev/papr-vpd", O_RDONLY);
int vpdfd = ioctl(devfd, PAPR_VPD_CREATE_HANDLE, &plc);
size_t size = lseek(vpdfd, 0, SEEK_END);
char *buf = malloc(size);
pread(devfd, buf, size, 0);
When a file descriptor is obtained from ioctl(PAPR_VPD_CREATE_HANDLE),
the file contains the result of a complete ibm,get-vpd sequence. The
file contents are immutable from the POV of user space. To get a new
view of the VPD, the client must create a new handle.
This design choice insulates user space from most of the complexities
that ibm,get-vpd brings:
* ibm,get-vpd must be called more than once to obtain complete
results.
* Only one ibm,get-vpd call sequence should be in progress at a time;
interleaved sequences will disrupt each other. Callers must have a
protocol for serializing their use of the function.
* A call sequence in progress may receive a "VPD changed, try again"
status, requiring the client to abandon the sequence and start
over.
The memory required for the VPD buffers seems acceptable, around 20KB
for all VPD on one of my systems. And the value of the
/rtas/ibm,vpd-size DT property (the estimated maximum size of VPD) is
consistently 300KB across various systems I've checked.
I've implemented support for this new ABI in the rtas_get_vpd()
function in librtas, which the vpdupdate command currently uses to
populate its VPD database. I've verified that an unmodified vpdupdate
binary generates an identical database when using a librtas.so that
prefers the new ABI.
Along with the papr-vpd.h header exposed to user space, this
introduces a common papr-miscdev.h uapi header to share a base ioctl
ID with similar drivers to come.

Documentation: Destage TEE subsystem documentation
Add a separate documentation directory for TEE subsystem since it is a standalone subsystem which already offers devices consumed by multiple different subsystem drivers. Split overall TEE subsystem documentation modularly where: - The userspace API has been moved to Documentation/userspace-api/tee.rst. - The driver API has been moved to Documentation/driver-api/tee.rst. - The first module covers the overview of TEE subsystem. - The further modules are dedicated to different TEE implementations like: - OP-TEE - AMD-TEE - and so on for future TEE implementation support.

LSM: syscalls for current process attributes
Create a system call lsm_get_self_attr() to provide the security
module maintained attributes of the current process.
Create a system call lsm_set_self_attr() to set a security
module maintained attribute of the current process.
Historically these attributes have been exposed to user space via
entries in procfs under /proc/self/attr.
The attribute value is provided in a lsm_ctx structure. The structure
identifies the size of the attribute, and the attribute value. The format
of the attribute value is defined by the security module. A flags field
is included for LSM specific information. It is currently unused and must
be 0. The total size of the data, including the lsm_ctx structure and any
padding, is maintained as well.
struct lsm_ctx {
__u64 id;
__u64 flags;
__u64 len;
__u64 ctx_len;
__u8 ctx[];
};
Two new LSM hooks are used to interface with the LSMs.
security_getselfattr() collects the lsm_ctx values from the
LSMs that support the hook, accounting for space requirements.
security_setselfattr() identifies which LSM the attribute is
intended for and passes it along.

LSM: Identify modules by more than name
Create a struct lsm_id to contain identifying information about Linux Security Modules (LSMs). At inception this contains the name of the module and an identifier associated with the security module. Change the security_add_hooks() interface to use this structure. Change the individual modules to maintain their own struct lsm_id and pass it to security_add_hooks(). The values are for LSM identifiers are defined in a new UAPI header file linux/lsm.h. Each existing LSM has been updated to include it's LSMID in the lsm_id. The LSM ID values are sequential, with the oldest module LSM_ID_CAPABILITY being the lowest value and the existing modules numbered in the order they were included in the main line kernel. This is an arbitrary convention for assigning the values, but none better presents itself. The value 0 is defined as being invalid. The values 1-99 are reserved for any special case uses which may arise in the future. This may include attributes of the LSM infrastructure itself, possibly related to namespacing or network attribute management. A special range is identified for such attributes to help reduce confusion for developers unfamiliar with LSMs. LSM attribute values are defined for the attributes presented by modules that are available today. As with the LSM IDs, The value 0 is defined as being invalid. The values 1-99 are reserved for any special case uses which may arise in the future.

landlock: Allow FS topology changes for domains without such rule type
Allow mount point and root directory changes when there is no filesystem rule tied to the current Landlock domain. This doesn't change anything for now because a domain must have at least a (filesystem) rule, but this will change when other rule types will come. For instance, a domain only restricting the network should have no impact on filesystem restrictions. Add a new get_current_fs_domain() helper to quickly check filesystem rule existence for all filesystem LSM hooks. Remove unnecessary inlining.

netlink: add variable-length / auto integers
We currently push everyone to use padding to align 64b values in netlink. Un-padded nla_put_u64() doesn't even exist any more. The story behind this possibly start with this thread: https://lore.kernel.org/netdev/20121204.130914.1457976839967676240.davem@davemloft.net/ where DaveM was concerned about the alignment of a structure containing 64b stats. If user space tries to access such struct directly: struct some_stats *stats = nla_data(attr); printf("A: %llu", stats->a); lack of alignment may become problematic for some architectures. These days we most often put every single member in a separate attribute, meaning that the code above would use a helper like nla_get_u64(), which can deal with alignment internally. Even for arches which don't have good unaligned access - access aligned to 4B should be pretty efficient. Kernel and well known libraries deal with unaligned input already. Padded 64b is quite space-inefficient (64b + pad means at worst 16B per attr vs 32b which takes 8B). It is also more typing: if (nla_put_u64_pad(rsp, NETDEV_A_SOMETHING_SOMETHING, value, NETDEV_A_SOMETHING_PAD)) Create a new attribute type which will use 32 bits at netlink level if value is small enough (probably most of the time?), and (4B-aligned) 64 bits otherwise. Kernel API is just: if (nla_put_uint(rsp, NETDEV_A_SOMETHING_SOMETHING, value)) Calling this new type "just" sint / uint with no specific size will hopefully also make people more comfortable with using it. Currently telling people "don't use u8, you may need the bits, and netlink will round up to 4B, anyway" is the #1 comment we give to newcomers. In terms of netlink layout it looks like this: 0 4 8 12 16 32b: [nlattr][ u32 ] 64b: [ pad ][nlattr][ u64 ] uint(32) [nlattr][ u32 ] uint(64) [nlattr][ u64 ] Signed-off-by: Jakub Kicinski <kuba@kernel.org> Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.

Documentation work keeps chugging along; stuff for 6.6 includes:
- Work from Carlos Bilbao to integrate rustdoc output into the generated
HTML documentation. This took some work to figure out how to do it
without slowing the docs build and without creating people who don't have
Rust installed, but Carlos got there.
- Move the loongarch and mips architecture documentation under
Documentation/arch/.
- Some more maintainer documentation from Jakub
...plus the usual assortment of updates, translations, and fixes.

Char/Misc drivers for 6.4-rc1
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 issues.

Networking changes for 6.4.
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.

Commit volume in documentation is relatively low this time, but there is
still a fair amount going on, including:
- Reorganizing the architecture-specific documentation under
Documentation/arch. This makes the structure match the source directory
and helps to clean up the mess that is the top-level Documentation
directory a bit. This work creates the new directory and moves x86 and
most of the less-active architectures there. The current plan is to move
the rest of the architectures in 6.5, with the patches going through the
appropriate subsystem trees.
- Some more Spanish translations and maintenance of the Italian
translation.
- A new "Kernel contribution maturity model" document from Ted.
- A new tutorial on quickly building a trimmed kernel from Thorsten.
Plus the usual set of updates and fixes.

media: v4l2-subdev: Add new ioctl for client capabilities
Add new ioctls to set and get subdev client capabilities. Client in this context means the userspace application which opens the subdev device node. The client capabilities are stored in the file handle of the opened subdev device node, and the client must set the capabilities for each opened subdev. For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which indicates that the client is streams-aware. The reason for needing such a flag is as follows: Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain reserved fields (usually a single array field). These reserved fields can be used to extend the ioctl. The userspace is required to zero the reserved fields. We recently added a new 'stream' field to many of these structs, and the space for the field was taken from these reserved arrays. The assumption was that these new 'stream' fields are always initialized to zero if the userspace does not use them. This was a mistake, as, as mentioned above, the userspace is required to zero the _reserved_ fields. In other words, there is no requirement to zero this new stream field, and if the userspace doesn't use the field (which is the case for all userspace applications at the moment), the field may contain random data. This shows that the way the reserved fields are defined in v4l2 is, in my opinion, somewhat broken, but there is nothing to do about that. To fix this issue we need a way for the userspace to tell the kernel that the userspace has indeed set the 'stream' field, and it's fine for the kernel to access it. This is achieved with the new ioctl, which the userspace should usually use right after opening the subdev device node.

I relicensed Netlink spec code to GPL-2.0 OR BSD-3-Clause but
we still put a slightly different license on the uAPI header
than the rest of the code. Use the Linux-syscall-note on all
the specs and all generated code. It's moot for kernel code,
but should not hurt. This way the licenses match everywhere.

char: pcmcia: remove all the drivers
These char PCMCIA drivers are buggy[1] and receive only minimal care. It was concluded[2], that we should try to remove most pcmcia drivers completely. Let's start with these char broken one. Note that I also removed a UAPI header: include/uapi/linux/cm4000_cs.h. I found only coccinelle tests mentioning some ioctl constants from that file. But they are not actually used. Anyway, should someone complain, we may reintroduce the header (or its parts).

ynl: re-license uniformly under GPL-2.0 OR BSD-3-Clause
I was intending to make all the Netlink Spec code BSD-3-Clause to ease the adoption but it appears that: - I fumbled the uAPI and used "GPL WITH uAPI note" there - it gives people pause as they expect GPL in the kernel As suggested by Chuck re-license under dual. This gives us benefit of full BSD freedom while fulfilling the broad "kernel is under GPL" expectations.

Networking changes for 6.3.
Core
----
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used
to describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols
---------
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP
path manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF
---
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key
to better support decap on GRE tunnel devices not operating
in collect metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk
and bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols
by livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter
---------
- Remove the CLUSTERIP target. It has been marked as obsolete
for years, and we still have WARN splats wrt. races of
the out-of-band /proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to
the existing 'delete' commands, but do not return an error if
the referenced object (set, chain, rule...) did not exist.
Driver API
----------
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into multiple
files, drop some of the unnecessarily granular locks and factor out
common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless Extensions
for Wi-Fi 7 devices at all. Everyone should switch to using nl80211
interface instead.
- Improve the CAN bit timing configuration. Use extack to return error
messages directly to user space, update the SJW handling, including
the definition of a new default value that will benefit CAN-FD
controllers, by increasing their oscillator tolerance.

Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core:
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used to
describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols:
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF:
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols by
livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter:
- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.
Driver API:
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.
- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.
