docs: cec: show broken xrefs and show TOC instead of cec.h content
Enable xref broken warnings. While here, change the output to only show cross-references, as there's no need to show the entire cec.h header at the docs.

It has been a relatively busy cycle in docsland, with changes all over:
- Bring the kernel memory-model docs into the Sphinx build in the "literal
include" mode.
- Lots of build-infrastructure work, further cleaning up long-term
kernel-doc technical debt. The sphinx-pre-install tool has been
converted to Python and updated for current systems.
- A new tool to detect when documents have been moved and generate HTML
redirects; this can be used on kernel.org (or any other site hosting the
rendered docs) to avoid breaking links.
- Automated processing of the YAML files describing the netlink protocol.
- A significant update of the maintainer's PGP guide.
...and a seemingly endless series of typo fixes, build-problem fixes, etc.

Networking changes for 6.18.
Core & protocols
----------------
- Improve drop account scalability on NUMA hosts for RAW and UDP sockets
and the backlog, almost doubling the Pps capacity under DoS.
- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance by
an additional 50%, even more under extreme conditions.
- Add support for PSP encryption of TCP connections; this mechanism has
some similarities with IPsec and TLS, but offers superior HW offloads
capabilities.
- Ongoing work to support Accurate ECN for TCP. AccECN allows more than
one congestion notification signal per RTT and is a building block for
Low Latency, Low Loss, and Scalable Throughput (L4S).
- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath.
- Refactor skb deferral free to better scale on large multi-NUMA hosts,
this improves TCP and UDP RX performances significantly on such HW.
- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds.
- Improve handling of setups with a large number of nexthop, making dump
operating scaling linearly and avoiding unneeded synchronize_rcu() on
delete.
- Improve bridge handling of VLAN FDB, storing a single entry per bridge
instead of one entry per port; this makes the dump order of magnitude
faster on large switches.
- Restore IP ID correctly for encapsulated packets at GSO segmentation
time, allowing GRO to merge packets in more scenarios.
- Improve netfilter matching performance on large sets.
- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting recent
TCP autotuning changes.
- Allow bridges to redirect to a backup port when the bridge port is
administratively down.
- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups.
- Add RCU safety to dst->dev, closing a lot of possible races.
- A significant crypto library API for SCTP, MPTCP and IPv6 SR, reducing
code duplication.
- Supports pulling data from an skb frag into the linear area of an XDP
buffer.
Things we sprinkled into general kernel code
--------------------------------------------
- Generate netlink documentation from YAML using an integrated
YAML parser.
Driver API
----------
- Support using IPv6 Flow Label in Rx hash computation and RSS queue
selection.
- Introduce API for fetching the DMA device for a given queue, allowing
TCP zerocopy RX on more H/W setups.
- Make XDP helpers compatible with unreadable memory, allowing more
easily building DevMem-enabled drivers with a unified XDP/skbs
datapath.
- Add a new dedicated ethtool callback enabling drivers to provide the
number of RX rings directly, improving efficiency and clarity in RX
ring queries and RSS configuration.
- Introduce a burst period for the health reporter, allowing better
handling of multiple errors due to the same root cause.
- Support for DPLL phase offset exponential moving average, controlling
the average smoothing factor.
Device drivers

- Add a new SpacemiT driver for K1 ethernet MAC.
- Add a generic abstraction for shared memory communication devices
(dibps)

iommufd 6.17 merge window pull
- IOMMU HW now has features to directly assign HW command queues to a
guest VM. In this mode the command queue operates on a limited set of
invalidation commands that are suitable for improving guest invalidation
performance and easy for the HW to virtualize.
This PR brings the generic infrastructure to allow IOMMU drivers to
expose such command queues through the iommufd uAPI, mmap the doorbell
pages, and get the guest physical range for the command queue ring
itself.
- An implementation for the NVIDIA SMMUv3 extension "cmdqv" is built on
the new iommufd command queue features. It works with the existing SMMU
driver support for cmdqv in guest VMs.
- Many precursor cleanups and improvements to support the above cleanly,
changes to the general ioctl and object helpers, driver support for
VDEVICE, and mmap pgoff cookie infrastructure.
- Sequence VDEVICE destruction to always happen before VFIO device
destruction. When using the above type features, and also in future
confidential compute, the internal virtual device representation becomes
linked to HW or CC TSM configuration and objects. If a VFIO device is
removed from iommufd those HW objects should also be cleaned up to
prevent a sort of UAF. This became important now that we have HW backing
the VDEVICE.
- Fix one syzkaller found error related to math overflows during iova

"This broadly brings the assigned HW command queue support to iommufd.
This feature is used to improve SVA performance in VMs by avoiding
paravirtualization traps during SVA invalidations.
Along the way I think some of the core logic is in a much better state
to support future driver backed features.

It has been a relatively busy cycle for docs, especially the build system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the turn of
the millennium. Over the following 25 years, it accumulated a vast
amount of cruft, all in a language few people want to deal with anymore.
Mauro's Python replacement in 6.16 faithfully reproduced all of the cruft
in the hope of avoiding regressions. Now that we have a more reasonable
code base, though, we can work on cleaning it up; many of the changes
this time around are toward that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository links.
...and lots of fixes and updates.

media: uvcvideo: Introduce V4L2_META_FMT_UVC_MSXU_1_5
The UVC driver provides two metadata types V4L2_META_FMT_UVC, and V4L2_META_FMT_D4XX. The only difference between the two of them is that V4L2_META_FMT_UVC only copies PTS, SCR, size and flags, and V4L2_META_FMT_D4XX copies the whole metadata section. Now we only enable V4L2_META_FMT_D4XX for the Intel D4xx family of devices, but it is useful to have the whole metadata payload for any device where vendors include other metadata, such as the one described by Microsoft: https://learn.microsoft.com/en-us/windows-hardware/drivers/stream/mf-capture-metadata This patch introduces a new format V4L2_META_FMT_UVC_MSXU_1_5, that is identical to V4L2_META_FMT_D4XX. Let the user enable this format with a quirk for now. This way they can test if their devices provide useful metadata without rebuilding the kernel. They can later contribute patches to auto-quirk their devices. We will also work in methods to auto-detect devices compatible with this new metadata format.

dma-buf: heaps: Give default CMA heap a fixed name
The CMA heap's name in devtmpfs can vary depending on how the heap is defined. Its name defaults to "reserved", but if a CMA area is defined in the devicetree, the heap takes on the devicetree node's name, such as "default-pool" or "linux,cma". To simplify naming, unconditionally name it "default_cma_region", but keep a legacy node in place backed by the same underlying allocator for backwards compatibility.

block: remove pktcdvd driver
This driver has long outlived it's utility, and it's broken and unloved. The main use case for this was direct mount with UDF of cd-rw drives that required 32kb packets. It would collect writes into that size and write them out in multiples of that. That's not a common use case anymore, the world has moved on from those kinds of media. To make matters worse, it's actively breaking setups where it's not even required or useful.

media: v4l2: Add Renesas Camera Receiver Unit pixel formats
The Renesas Camera Receiver Unit in the RZ/V2H SoC can output RAW data captured from an image sensor without conversion to an RGB/YUV format.

Networking changes for 6.16.
Core
----
- Implement the Device Memory TCP transmit path, allowing zero-copy
data transmission on top of TCP from e.g. GPU memory to the wire.
- Move all the IPv6 routing tables management outside the RTNL scope,
under its own lock and RCU. The route control path is now 3x times
faster.
- Convert queue related netlink ops to instance lock, reducing
again the scope of the RTNL lock. This improves the control plane
scalability.
- Refactor the software crc32c implementation, removing unneeded
abstraction layers and improving significantly the related
micro-benchmarks.
- Optimize the GRO engine for UDP-tunneled traffic, for a 10%
performance improvement in related stream tests.
- Cover more per-CPU storage with local nested BH locking; this is a
prep work to remove the current per-CPU lock in local_bh_disable()
on PREMPT_RT.
- Introduce and use nlmsg_payload helper, combining buffer bounds
verification with accessing payload carried by netlink messages.
Netfilter
---------
- Rewrite the procfs conntrack table implementation, improving
considerably the dump performance. A lot of user-space tools
still use this interface.
- Implement support for wildcard netdevice in netdev basechain
and flowtables.
- Integrate conntrack information into nft trace infrastructure.
- Export set count and backend name to userspace, for better
introspection.
BPF
---
- BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops
programs and can be controlled in similar way to traditional qdiscs
using the "tc qdisc" command.
- Refactor the UDP socket iterator, addressing long standing issues
WRT duplicate hits or missed sockets.
Protocols
---------
- Improve TCP receive buffer auto-tuning and increase the default
upper bound for the receive buffer; overall this improves the single
flow maximum thoughput on 200Gbs link by over 60%.
- Add AFS GSSAPI security class to AF_RXRPC; it provides transport
security for connections to the AFS fileserver and VL server.
- Improve TCP multipath routing, so that the sources address always
matches the nexthop device.
- Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS,
and thus preventing DoS caused by passing around problematic FDs.
- Retire DCCP socket. DCCP only receives updates for bugs, and major
distros disable it by default. Its removal allows for better
organisation of TCP fields to reduce the number of cache lines hit
in the fast path.
- Extend TCP drop-reason support to cover PAWS checks.
Driver API
----------
- Reorganize PTP ioctl flag support to require an explicit opt-in for
the drivers, avoiding the problem of drivers not rejecting new
unsupported flags.
- Converted several device drivers to timestamping APIs.
- Introduce per-PHY ethtool dump helpers, improving the support for
dump operations targeting PHYs.
Tests and tooling
-----------------
- Add support for classic netlink in user space C codegen, so that
ynl-c can now read, create and modify links, routes addresses and
qdisc layer configuration.
- Add ynl sub-types for binary attributes, allowing ynl-c to output
known struct instead of raw binary data, clarifying the classic
netlink output.
- Extend MPTCP selftests to improve the code-coverage.
- Add tests for XDP tail adjustment in AF_XDP.
New hardware / drivers
----------------------
- OpenVPN virtual driver: offload OpenVPN data channels processing
to the kernel-space, increasing the data transfer throughput WRT
the user-space implementation.
- Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC.
- Broadcom asp-v3.0 ethernet driver.
- AMD Renoir ethernet device.
- ReakTek MT9888 2.5G ethernet PHY driver.
- Aeonsemi 10G C45 PHYs driver.

A moderately busy cycle for documentation this time around:
- The most significant change is the replacement of the old kernel-doc
script (a monstrous collection of Perl regexes that predates the Git era)
with a Python reimplementation. That, too, is a horrifying collection of
regexes, but in a much cleaner and more maintainable structure that
integrates far better with the Sphinx build system.
This change has been in linux-next for the full 6.15 cycle; the small
number of problems that turned up have been addressed, seemingly to
everybody's satisfaction. The Perl kernel-doc script remains in tree (as
scripts/kernel-doc.pl) and can be used with a command-line option if need
be. Unless some reason to keep it around materializes, it will probably
go away in 6.17.

misc: amd-sbi: Add support for AMD_SBI IOCTL
The present sbrmi module only support reporting power via hwmon. However, AMD data center range of processors support various system management functionality using custom protocols defined in Advanced Platform Management Link (APML) specification. Register a miscdevice, which creates a device /dev/sbrmiX with an IOCTL interface for the user space to invoke the APML Mailbox protocol, which is already defined in sbrmi_mailbox_xfer(). The APML protocols depend on a set of RMI registers. Having an IOCTL as a single entry point will help in providing synchronization among these protocols as multiple transactions on RMI register set may create race condition. Support for other protocols will be added in subsequent patches. APML mailbox protocol returns additional error codes written by SMU firmware in the out-bound register 0x37. These errors include, invalid core, message not supported over platform and others. This additional error codes can be used to provide more details to user space. Open-sourced and widely used https://github.com/amd/esmi_oob_library will continue to provide user-space programmable API.

powerpc/pseries: Add a char driver for physical-attestation RTAS
The RTAS call ibm,physical-attestation is used to retrieve
information about the trusted boot state of the firmware and
hypervisor on the system, and also Trusted Platform Modules (TPM)
data if the system is TCG 2.0 compliant.
This RTAS interface expects the caller to define different command
structs such as RetrieveTPMLog, RetrievePlatformCertificat and etc,
in a work area with a maximum size of 4K bytes and the response
buffer will be returned in the same work area.
The current implementation of this RTAS function is in the user
space but allocation of the work area is restricted with the system
lockdown. So this patch implements this RTAS function in the kernel
and expose to the user space with open/ioctl/read interfaces.
PAPR (2.13+ 21.3 ibm,physical-attestation) defines RTAS function:
- Pass the command struct to obtain the response buffer for the
specific command.
- This RTAS function is sequence RTAS call and has to issue RTAS
call multiple times to get the complete response buffer (max 64K).
The hypervisor expects the first RTAS call with the sequence 1 and
the subsequent calls with the sequence number returned from the
previous calls.
Expose these interfaces to user space with a
/dev/papr-physical-attestation character device using the following
programming model:
int devfd = open("/dev/papr-physical-attestation");
int fd = ioctl(devfd, PAPR_PHY_ATTEST_IOC_HANDLE,
struct papr_phy_attest_io_block);
- The user space defines the command struct and requests the
response for any command.
- Obtain the complete response buffer and returned the buffer as
blob to the command specific FD.
size = read(fd, buf, len);
- Can retrieve the response buffer once or multiple times until the
end of BLOB buffer.
Implemented this new kernel ABI support in librtas library for
system lockdown

powerpc/pseries: Add papr-platform-dump character driver for dump retrieval
ibm,platform-dump RTAS call in combination with writable mapping
/dev/mem is issued to collect platform dump from the hypervisor
and may need multiple calls to get the complete dump. The current
implementation uses rtas_platform_dump() API provided by librtas
library to issue these RTAS calls. But /dev/mem access by the
user space is prohibited under system lockdown.
The solution should be to restrict access to RTAS function in user
space and provide kernel interfaces to collect dump. This patch
adds papr-platform-dump character driver and expose standard
interfaces such as open / ioctl/ read to user space in ways that
are compatible with lockdown.
PAPR (7.3.3.4.1 ibm,platform-dump) provides a method to obtain
the complete dump:
- Each dump will be identified by ID called dump tag.
- A sequence of RTAS calls have to be issued until retrieve the
complete dump. The hypervisor expects the first RTAS call with
the sequence 0 and the subsequent calls with the sequence
number returned from the previous calls.
- The hypervisor returns "dump complete" status once the complete
dump is retrieved. But expects one more RTAS call from the
partition with the NULL buffer to invalidate dump which means
the dump will be removed in the hypervisor.
- Sequence of calls are allowed with different dump IDs at the
same time but not with the same dump ID.
Expose these interfaces to user space with a /dev/papr-platform-dump
character device using the following programming model:
int devfd = open("/dev/papr-platform-dump", O_RDONLY);
int fd = ioctl(devfd,PAPR_PLATFORM_DUMP_IOC_CREATE_HANDLE, &dump_id)
- Restrict user space to access with the same dump ID.
Typically we do not expect user space requests the dump
again for the same dump ID.
char *buf = malloc(size);
length = read(fd, buf, size);
- size should be minimum 1K based on PAPR and <= 4K based
on RTAS work area size. It will be restrict to RTAS work
area size. Using 4K work area based on the current
implementation in librtas library
- Each read call issue RTAS call to get the data based on
the size requirement and returns bytes returned from the
hypervisor
- If the previous call returns dump complete status, the
next read returns 0 like EOF.
ret = ioctl(PAPR_PLATFORM_DUMP_IOC_INVALIDATE, &dump_id)
- RTAS call with NULL buffer to invalidates the dump.
The read API should use the file descriptor obtained from ioctl
based on dump ID so that gets dump contents for the corresponding
dump ID. Implemented support in librtas (rtas_platform_dump()) for
this new ABI to support system lockdown.

powerpc/pseries: Define papr_indices_io_block for papr-indices ioctls
To issue ibm,get-indices, ibm,set-dynamic-indicator and ibm,get-dynamic-sensor-state in the user space, the RMO buffer is allocated for the work area which is restricted under system lockdown. So instead of user space execution, the kernel will provide /dev/papr-indices interface to execute these RTAS calls. The user space assigns data in papr_indices_io_block struct depends on the specific HCALL and passes to the following ioctls: PAPR_INDICES_IOC_GET: Use for ibm,get-indices. Returns a get-indices handle fd to read data. PAPR_DYNAMIC_SENSOR_IOC_GET: Use for ibm,get-dynamic-sensor-state.

netlink: specs: rename rtnetlink specs in accordance with family name
The rtnetlink family names are set to rt-$name within the YAML but the files are called rt_$name. C codegen assumes that the generated file name will match the family. The use of dashes is in line with our general expectation that name properties in the spec use dashes not underscores (even tho, as Donald points out most genl families use underscores in the name). We have 3 un-ideal options to choose from: - accept the slight inconsistency with old families using _, or - accept the slight annoyance with all languages having to do s/-/_/ when looking up family ID, or - accept the inconsistency with all name properties in new YAML spec being separated with - and just the family name always using _. Pick option 1 and rename the rtnl spec files.

iommufd 6.15 merge window pull
Two significant new items:
- Allow reporting IOMMU HW events to userspace when the events are clearly
linked to a device. This is linked to the VIOMMU object and is intended to
be used by a VMM to forward HW events to the virtual machine as part of
emulating a vIOMMU. ARM SMMUv3 is the first driver to use this
mechanism. Like the existing fault events the data is delivered through
a simple FD returning event records on read().
- PASID support in VFIO. "Process Address Space ID" is a PCI feature that
allows the device to tag all PCI DMA operations with an ID. The IOMMU
will then use the ID to select a unique translation for those DMAs. This
is part of Intel's vIOMMU support as VT-D HW requires the hypervisor to
manage each PASID entry. The support is generic so any VFIO user could
attach any translation to a PASID, and the support should work on ARM
SMMUv3 as well. AMD requires additional driver work.
Some minor updates, along with fixes:
- Prevent using nested parents with fault's, no driver support today
- Put a single "cookie_type" value in the iommu_domain to indicate what
owns the various opaque owner fields

fwctl first pull request
fwctl is a new subsystem intended to bring some common rules and order to the growing pattern of exposing a secure FW interface directly to userspace. Unlike existing places like RDMA/DRM/VFIO/uacce that are exposing a device for datapath operations fwctl is focused on debugging, configuration and provisioning of the device. It will not have the necessary features like interrupt delivery to support a datapath. This concept is similar to the long standing practice in the "HW" RAID space of having a device specific misc device to manage the RAID controller FW. fwctl generalizes this notion of a companion debug and management interface that goes along with a dataplane implemented in an appropriate subsystem. There have been three LWN articles written discussing various aspects of this: https://lwn.net/Articles/955001/ https://lwn.net/Articles/969383/ https://lwn.net/Articles/990802/ This pull requests includes three drivers to launch the subsystem: - CXL provides a vendor scheme for executing commands and a way to learn the 'command effects' (ie the security properties) of such commands. The fwctl driver allows access to these mechanism within the fwctl security model - mlx5 is family of networking products, the driver supports all current Mellanox HW still receiving FW feature updates. This includes RDMA multiprotocol NICs like ConnectX and the Bluefield family of Smart NICs. - AMD/Pensando Distributed Services card is a multi protocol Smart NIC with a multi PCI function design. fwctl works on the management PCI function following a 'command effects' model similar to CXL. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQRRRCHOFoQz/8F5bUaFwuHvBreFYQUCZ939zQAKCRCFwuHvBreF YdOoAQCJq59/UC7lXU+sOsR6LISaDVTT5jAweBo0o036P9+DNAEA1iQdZ/GK2yCJ Ub33Xo9L+hzIpIbCouI3BtCXqymybAg= =f5YG -----END PGP SIGNATURE----- Merge tag 'for-linus-fwctl' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma Pull fwctl subsystem from Jason Gunthorpe: "fwctl is a new subsystem intended to bring some common rules and order to the growing pattern of exposing a secure FW interface directly to userspace.

Drivers: hv: Introduce mshv_root module to expose /dev/mshv to VMMs
Provide a set of IOCTLs for creating and managing child partitions when running as root partition on Hyper-V. The new driver is enabled via CONFIG_MSHV_ROOT. A brief overview of the interface: MSHV_CREATE_PARTITION is the entry point, returning a file descriptor representing a child partition. IOCTLs on this fd can be used to map memory, create VPs, etc. Creating a VP returns another file descriptor representing that VP which in turn has another set of corresponding IOCTLs for running the VP, getting/setting state, etc. MSHV_ROOT_HVCALL is a generic "passthrough" hypercall IOCTL which can be used for a number of partition or VP hypercalls. This is for hypercalls that do not affect any state in the kernel driver, such as getting and setting VP registers and partition properties, translating addresses, etc. It is "passthrough" because the binary input and output for the hypercall is only interpreted by the VMM - the kernel driver does nothing but insert the VP and partition id where necessary (which are always in the same place), and execute the hypercall.

landlock: Clarify IPC scoping documentation
* Clarify terminology * Stop mixing the unix(7) and signal(7) aspects in the explanation. Terminology: * The *IPC Scope* of a Landlock domain is that Landlock domain and its nested domains. * An *operation* (e.g., signaling, connecting to abstract UDS) is said to be *scoped within a domain* when the flag for that operation was set at ruleset creation time. This means that for the purpose of this operation, only processes within the domain's IPC scope are reachable.

coresight: docs: Remove target sink from examples
Previously the sink had to be specified, but now it auto selects one by default. Including a sink in the examples causes issues when copy pasting the command because it might not work if that sink isn't present.

Make the text a but more concise now that it's in the advanced section, and similarly for removing the old kernel advice.

fwctl/mlx5: Support for communicating with mlx5 fw
mlx5 FW has a built in security context called UID. Each UID has a set of permissions controlled by the kernel when it is created and every command is tagged by the kernel with a particular UID. In general commands cannot reach objects outside of their UID and commands cannot exceed their UID's permissions. These restrictions are enforced by FW. This mechanism has long been used in RDMA for the devx interface where RDMA will sent commands directly to the FW and the UID limitations restrict those commands to a ib_device/verbs security domain. For instance commands that would effect other VFs, or global device resources. The model is suitable for unprivileged userspace to operate the RDMA functionality. The UID has been extended with a "tools resources" permission which allows additional commands and sub-commands that are intended to match with the scope limitations set in FWCTL. This is an alternative design to the "command intent log" where the FW does the enforcement rather than having the FW report the enforcement the kernel should do. Consistent with the fwctl definitions the "tools resources" security context is limited to the FWCTL_RPC_CONFIGURATION, FWCTL_RPC_DEBUG_READ_ONLY, FWCTL_RPC_DEBUG_WRITE, and FWCTL_RPC_DEBUG_WRITE_FULL security scopes. Like RDMA devx, each opened fwctl file descriptor will get a unique UID associated with each file descriptor. The fwctl driver is kept simple and we reject commands that can create objects as the UID mechanism relies on the kernel to track and destroy objects prior to detroying the UID. Filtering into fwctl sub scopes is done inside the driver with a switch statement. This substantially limits what is possible to primarily query functions ad a few limited set operations. mlx5 already has a robust infrastructure for delivering RPC messages to fw. Trivially connect fwctl's RPC mechanism to mlx5_cmd_do(). Enforce the User Context ID in every RPC header accepted from the FD so the FW knows the security context of the issuing ID.

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".

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.

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"
