dma-mapping: benchmark: add support for dma_map_sg
Support for dma scatter-gather mapping and is intended for testing mapping performance. It achieves by introducing the dma_sg_map_param structure and related functions, which enable the implementation of scatter-gather mapping preparation, mapping, and unmapping operations. Additionally, the dma_map_benchmark_ops array is updated to include operations for scatter-gather mapping. This commit aims to provide a wider range of mapping performance test to cater to different scenarios.

dma-mapping: benchmark: modify the framework to adapt to more map modes
This patch adjusts the DMA map benchmark framework to make the DMA map benchmark framework more flexible and adaptable to other mapping modes in the future. By abstracting the framework into five interfaces: prepare, unprepare, initialize_data, do_map, and do_unmap. The new map schema can be introduced more easily without major modifications to the existing code structure.

dma-buf: Include ioctl.h in UAPI header
include/uapi/linux/dma-buf.h uses several macros from ioctl.h to define its ioctl commands. However, it does not include ioctl.h itself. So, if userspace source code tries to include the dma-buf.h file without including ioctl.h, it can result in build failures. Therefore, include ioctl.h in the dma-buf UAPI header.

RDMA/core: Add netlink command to modify FRMR aging
Allow users to set FRMR pools aging timer through netlink. This functionality will allow user to control how long handles reside in the kernel before being destroyed, thus being able to tune the tradeoff between memory and HW object consumption and memory registration optimization. Since FRMR pools is highly beneficial for application restart scenarios, this command allows users to modify the aging timer to their application restart time, making sure the FRMR handles deregistered on application teardown are kept for long enough in the pools for reuse in the application startup.

wifi: cfg80211: add support for IEEE 802.1X Authentication Protocol
Add an extended feature flag NL80211_EXT_FEATURE_IEEE8021X_AUTH to allow a driver to indicate support for the IEEE 802.1X authentication protocol in non-AP STA mode, as defined in "IEEE P802.11bi/D4.0, 12.16.5". In case of SME in userspace, the Authentication frame body is prepared in userspace while the driver finalizes the Authentication frame once it receives the required fields and elements. The driver indicates support for IEEE 802.1X authentication using the extended feature flag so that userspace can initiate IEEE 802.1X authentication. When the feature flag is set, process IEEE 802.1X Authentication frames from userspace in non-AP STA mode. If the flag is not set, reject IEEE 802.1X Authentication frames. Define a new authentication type NL80211_AUTHTYPE_IEEE8021X for IEEE 802.1X authentication.

wifi: cfg80211: add support to handle incumbent signal detected event from mac80211/driver
When any incumbent signal is detected by an AP/mesh interface operating in 6 GHz band, FCC mandates the AP/mesh to vacate the channels affected by it [1]. Add a new API cfg80211_incumbent_signal_notify() that can be used by mac80211 or drivers to notify the higher layers about the signal interference event with the interference bitmap in which each bit denotes the affected 20 MHz in the operating channel. Add support for the new nl80211 event and nl80211 attribute as well to notify userspace on the details about the interference event. Userspace is expected to process it and take further action - vacate the channel, or reduce the bandwidth.

Miscellaneous fixes:
- Fix zero_vruntime tracking when there's a single task running
- Fix slice protection logic
- Fix the ->vprot logic for reniced tasks
- Fix lag clamping in mixed slice workloads
- Fix objtool uaccess warning (and bug) in the
!CONFIG_RSEQ_SLICE_EXTENSION case caused by unexpected
un-inlining, which triggers with older compilers
- Fix a comment in the rseq registration rseq_size bound check code
- Fix a legacy RSEQ ABI quirk that handled 32-byte area sizes
differently, which special size we now reached naturally and
want to avoid. The visible ugliness of the new reserved field
will be avoided the next time the RSEQ area is extended.

Pull scheduler fixes from Ingo Molnar:
- Fix zero_vruntime tracking when there's a single task running
- Fix slice protection logic
- Fix the ->vprot logic for reniced tasks
- Fix lag clamping in mixed slice workloads
- Fix objtool uaccess warning (and bug) in the
!CONFIG_RSEQ_SLICE_EXTENSION case caused by unexpected un-inlining,
which triggers with older compilers
- Fix a comment in the rseq registration rseq_size bound check code
- Fix a legacy RSEQ ABI quirk that handled 32-byte area sizes
differently, which special size we now reached naturally and want to
avoid. The visible ugliness of the new reserved field will be avoided
the next time the RSEQ area is extended.

sched/deadline: Add reporting of runtime left & abs deadline to sched_getattr() for DEADLINE tasks
The SCHED_DEADLINE scheduler allows reading the statically configured run-time, deadline, and period parameters through the sched_getattr() system call. However, there is no immediate way to access, from user space, the current parameters used within the scheduler: the instantaneous runtime left in the current cycle, as well as the current absolute deadline. The `flags' sched_getattr() parameter, so far mandated to contain zero, now supports the SCHED_GETATTR_FLAG_DL_DYNAMIC=1 flag, to request retrieval of the leftover runtime and absolute deadline, converted to a CLOCK_MONOTONIC reference, instead of the statically configured parameters. This feature is useful for adaptive SCHED_DEADLINE tasks that need to modify their behavior depending on whether or not there is enough runtime left in the current period, and/or what is the current absolute deadline. Notes: - before returning the instantaneous parameters, the runtime is updated; - the abs deadline is returned shifted from rq_clock() to ktime_get_ns(), in CLOCK_MONOTONIC reference; this causes multiple invocations from the same period to return values that may differ for a few ns (showing some small drift), albeit the deadline doesn't move, in rq_clock() reference; - the abs deadline value returned to user-space, as unsigned 64-bit value, can represent nearly 585 years since boot time; - setting flags=0 provides the old behavior (retrieve static parameters). See also the notes from discussion held at OSPM 2025 on the topic "Making user space aware of current deadline-scheduler parameters".

drm/xe/uapi: Introduce a flag to disallow vm overcommit in fault mode
Some compute applications may try to allocate device memory to probe how much device memory is actually available, assuming that the application will be the only one running on the particular GPU. That strategy fails in fault mode since it allows VM overcommit. While this could be resolved in user-space it's further complicated by cgroups potentially restricting the amount of memory available to the application. Introduce a vm create flag, DRM_XE_VM_CREATE_NO_VM_OVERCOMMIT, that allows fault mode to mimic the behaviour of !fault mode WRT this. It blocks evicting same vm bos during VM_BIND processing. However, it does *not* block evicting same-vm bos during pagefault processing, preferring eviction rather than VM banning in OOM situations.

drm/nouveau: Add DRM_IOCTL_NOUVEAU_GET_ZCULL_INFO
Add kernel-side support for using the zcull hardware in nvidia gpus. zcull aims to improve memory bandwidth by using an early approximate depth test, similar to hierarchical Z on an AMD card. Add a new ioctl that exposes zcull information that has been read from the hardware. Userspace uses each of these parameters either in a heuristic for determining zcull region parameters or in the calculation of a buffer size. It appears the hardware hasn't changed its structure for these values since FERMI_C (circa 2011), so the assumption is that it won't change on us too quickly, and is therefore reasonable to include in UAPI. This bypasses the nvif layer and instead accesses nvkm_gr directly, which mirrors existing usage of nvkm_gr_units(). There is no nvif object for nvkm_gr yet, and adding one is not trivial.

rseq: slice ext: Ensure rseq feature size differs from original rseq size
Before rseq became extensible, its original size was 32 bytes even though the active rseq area was only 20 bytes. This had the following impact in terms of userspace ecosystem evolution: * The GNU libc between 2.35 and 2.39 expose a __rseq_size symbol set to 32, even though the size of the active rseq area is really 20. * The GNU libc 2.40 changes this __rseq_size to 20, thus making it express the active rseq area. * Starting from glibc 2.41, __rseq_size corresponds to the AT_RSEQ_FEATURE_SIZE from getauxval(3). This means that users of __rseq_size can always expect it to correspond to the active rseq area, except for the value 32, for which the active rseq area is 20 bytes. Exposing a 32 bytes feature size would make life needlessly painful for userspace. Therefore, add a reserved field at the end of the rseq area to bump the feature size to 33 bytes. This reserved field is expected to be replaced with whatever field will come next, expecting that this field will be larger than 1 byte. The effect of this change is to increase the size from 32 to 64 bytes before we actually have fields using that memory. Clarify the allocation size and alignment requirements in the struct rseq uapi comment. Change the value returned by getauxval(AT_RSEQ_ALIGN) to return the value of the active rseq area size rounded up to next power of 2, which guarantees that the rseq structure will always be aligned on the nearest power of two large enough to contain it, even as it grows. Change the alignment check in the rseq registration accordingly. This will minimize the amount of ABI corner-cases we need to document and require userspace to play games with. The rule stays simple when __rseq_size != 32: #define rseq_field_available(field) (__rseq_size >= offsetofend(struct rseq_abi, field)) Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://patch.msgid.link/20260220200642.1317826-3-mathieu.desnoyers@efficios.com |

fs: add generic FS_IOC_SHUTDOWN definitions
Currently, several filesystems (e.g., xfs, ext4, btrfs) implement a "shutdown" or "going down" ioctl to simulate filesystem force a shutdown. While they often use the same underlying numeric value, the definition is duplicated across filesystem headers or private definitions. Add generic definitions for FS_IOC_SHUTDOWN in uapi/linux/fs.h. This allows new filesystems (like ntfs) to implement this feature using a standard VFS definition and paves the way for existing filesystems to unify their definitions later. The flag names are standardized as FS_SHUTDOWN_* to be consistent with the ioctl name, replacing the historical GOING_DOWN naming convention. Reviewed-by: "Darrick J.

Musl defines its own struct ethhdr and thus defines __UAPI_DEF_ETHHDR to zero. To avoid struct redefinition errors, user space is therefore supposed to include netinet/if_ether.h before (or instead of) linux/if_ether.h. To relieve them from this burden, include the libc header here if not building for kernel space.

io_uring/bpf_filter: pass in expected filter payload size
It's quite possible that opcodes that have payloads attached to them, like IORING_OP_OPENAT/OPENAT2 or IORING_OP_SOCKET, that these paylods can change over time. For example, on the openat/openat2 side, the struct open_how argument is extensible, and could be extended in the future to allow further arguments to be passed in. Allow registration of a cBPF filter to give the size of the filter as seen by userspace. If that filter is for an opcode that takes extra payload data, allow it if the application payload expectation is the same size than the kernels. If that is the case, the kernel supports filtering on the payload that the application expects. If the size differs, the behavior depends on the IO_URING_BPF_FILTER_SZ_STRICT flag: 1) If IO_URING_BPF_FILTER_SZ_STRICT is set and the size expectation differs, fail the attempt to load the filter. 2) If IO_URING_BPF_FILTER_SZ_STRICT isn't set, allow the filter if the userspace pdu size is smaller than what the kernel offers. 3) Regardless if IO_URING_BPF_FILTER_SZ_STRICT, fail loading the filter if the userspace pdu size is bigger than what the kernel supports. An attempt to load a filter due to sizing will error with -EMSGSIZE. For that error, the registration struct will have filter->pdu_size populated with the pdu size that the kernel uses.

Merge tag 'vfs-7.0-rc1.misc.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull more misc vfs updates from Christian Brauner:
"Features:
- Optimize close_range() from O(range size) to O(active FDs) by using
find_next_bit() on the open_fds bitmap instead of linearly scanning
the entire requested range. This is a significant improvement for
large-range close operations on sparse file descriptor tables.
- Add FS_XFLAG_VERITY file attribute for fs-verity files, retrievable
via FS_IOC_FSGETXATTR and file_getattr(). The flag is read-only.
Add tracepoints for fs-verity enable and verify operations,
replacing the previously removed debug printk's.
- Prevent nfsd from exporting special kernel filesystems like pidfs
and nsfs. These filesystems have custom ->open() and ->permission()
export methods that are designed for open_by_handle_at(2) only and
are incompatible with nfsd. Update the exportfs documentation
accordingly.
Fixes:
- Fix KMSAN uninit-value in ovl_fill_real() where strcmp() was used
on a non-null-terminated decrypted directory entry name from
fscrypt. This triggered on encrypted lower layers when the
decrypted name buffer contained uninitialized tail data.
The fix also adds VFS-level name_is_dot(), name_is_dotdot(), and
name_is_dot_dotdot() helpers, replacing various open-coded "." and
".." checks across the tree.
- Fix read-only fsflags not being reset together with xflags in
vfs_fileattr_set(). Currently harmless since no read-only xflags
overlap with flags, but this would cause inconsistencies for any
future shared read-only flag
- Return -EREMOTE instead of -ESRCH from PIDFD_GET_INFO when the
target process is in a different pid namespace. This lets userspace
distinguish "process exited" from "process in another namespace",
matching glibc's pidfd_getpid() behavior
Cleanups:
- Use C-string literals in the Rust seq_file bindings, replacing the
kernel::c_str!() macro (available since Rust 1.77)
- Fix typo in d_walk_ret enum comment, add porting notes for the
readlink_copy() calling convention change"

Loongarch:
- Add more CPUCFG mask bits. - Improve feature detection. - Add lazy load support for FPU and binary translation (LBT) register state. - Fix return value for memory reads from and writes to in-kernel devices. - Add support for detecting preemption from within a guest. - Add KVM steal time test case to tools/selftests. ARM: - Add support for FEAT_IDST, allowing ID registers that are not implemented to be reported as a normal trap rather than as an UNDEF exception. - Add sanitisation of the VTCR_EL2 register, fixing a number of UXN/PXN/XN bugs in the process. - Full handling of RESx bits, instead of only RES0, and resulting in SCTLR_EL2 being added to the list of sanitised registers. - More pKVM fixes for features that are not supposed to be exposed to guests. - Make sure that MTE being disabled on the pKVM host doesn't give it the ability to attack the hypervisor. - Allow pKVM's host stage-2 mappings to use the Force Write Back version of the memory attributes by using the "pass-through' encoding. - Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the guest. - Preliminary work for guest GICv5 support. - A bunch of debugfs fixes, removing pointless custom iterators stored in guest data structures. - A small set of FPSIMD cleanups. - Selftest fixes addressing the incorrect alignment of page allocation. - Other assorted low-impact fixes and spelling fixes. RISC-V: - Fixes for issues discoverd by KVM API fuzzing in kvm_riscv_aia_imsic_has_attr(), kvm_riscv_aia_imsic_rw_attr(), and kvm_riscv_vcpu_aia_imsic_update() - Allow Zalasr, Zilsd and Zclsd extensions for Guest/VM - Transparent huge page support for hypervisor page tables - Adjust the number of available guest irq files based on MMIO register sizes found in the device tree or the ACPI tables - Add RISC-V specific paging modes to KVM selftests - Detect paging mode at runtime for selftests s390: - Performance improvement for vSIE (aka nested virtualization) - Completely new memory management. s390 was a special snowflake that enlisted help from the architecture's page table management to build hypervisor page tables, in particular enabling sharing the last level of page tables. This however was a lot of code (~3K lines) in order to support KVM, and also blocked several features. The biggest advantages is that the page size of userspace is completely independent of the page size used by the guest: userspace can mix normal pages, THPs and hugetlbfs as it sees fit, and in fact transparent hugepages were not possible before. It's also now possible to have nested guests and guests with huge pages running on the same host. - Maintainership change for s390 vfio-pci - Small quality of life improvement for protected guests x86: - Add support for giving the guest full ownership of PMU hardware (contexted switched around the fastpath run loop) and allowing direct access to data MSRs and PMCs (restricted by the vPMU model). KVM still intercepts access to control registers, e.g. to enforce event filtering and to prevent the guest from profiling sensitive host state. This is more accurate, since it has no risk of contention and thus dropped events, and also has significantly less overhead. For more information, see the commit message for merge commit |
