RISC-V updates for v7.0-rc8
Before v7.0 is released, fix a few issues with the CFI patchset,
merged earlier in v7.0-rc, that primarily affect interfaces to
non-kernel code:
- Improve the prctl() interface for per-task indirect branch landing
pad control to expand abbreviations and to resemble the speculation
control prctl() interface
- Expand the "LP" and "SS" abbreviations in the ptrace uapi header
file to "branch landing pad" and "shadow stack", to improve
readability
- Fix a typo in a CFI-related macro name in the ptrace uapi header
file
- Ensure that the indirect branch tracking state and shadow stack
state are unlocked immediately after an exec() on the new task so
that libc subsequently can control it
- While working in this area, clean up the kernel-internal,
cross-architecture prctl() function names by expanding the
abbreviations mentioned above

prctl: cfi: change the branch landing pad prctl()s to be more descriptive
Per Linus' comments requesting the replacement of "INDIR_BR_LP" in the
indirect branch tracking prctl()s with something more readable, and
suggesting the use of the speculation control prctl()s as an exemplar,
reimplement the prctl()s and related constants that control per-task
forward-edge control flow integrity.
This primarily involves two changes. First, the prctls are
restructured to resemble the style of the speculative execution
workaround control prctls PR_{GET,SET}_SPECULATION_CTRL, to make them
easier to extend in the future. Second, the "indir_br_lp" abbrevation
is expanded to "branch_landing_pads" to be less telegraphic. The
kselftest and documentation is adjusted accordingly.

netfilter: ctnetlink: use netlink policy range checks
Replace manual range and mask validations with netlink policy
annotations in ctnetlink code paths, so that the netlink core rejects
invalid values early and can generate extack errors.
- CTA_PROTOINFO_TCP_STATE: reject values > TCP_CONNTRACK_SYN_SENT2 at
policy level, removing the manual >= TCP_CONNTRACK_MAX check.
- CTA_PROTOINFO_TCP_WSCALE_ORIGINAL/REPLY: reject values > TCP_MAX_WSCALE
(14). The normal TCP option parsing path already clamps to this value,
but the ctnetlink path accepted 0-255, causing undefined behavior when
used as a u32 shift count.
- CTA_FILTER_ORIG_FLAGS/REPLY_FLAGS: use NLA_POLICY_MASK with
CTA_FILTER_F_ALL, removing the manual mask checks.
- CTA_EXPECT_FLAGS: use NLA_POLICY_MASK with NF_CT_EXPECT_MASK, adding
a new mask define grouping all valid expect flags.
Extracted from a broader nf-next patch by Florian Westphal, scoped to
ctnetlink for the fixes tree.

ARM:
- Correctly handle deeactivation of interrupts that were activated from
LRs. Since EOIcount only denotes deactivation of interrupts that
are not present in an LR, start EOIcount deactivation walk *after*
the last irq that made it into an LR.
- Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when
pKVM is already enabled -- not only thhis isn't possible (pKVM
will reject the call), but it is also useless: this can only
happen for a CPU that has already booted once, and the capability
will not change.
- Fix a couple of low-severity bugs in our S2 fault handling path,
affecting the recently introduced LS64 handling and the even more
esoteric handling of hwpoison in a nested context
- Address yet another syzkaller finding in the vgic initialisation,
where we would end-up destroying an uninitialised vgic with nasty
consequences
- Address an annoying case of pKVM failing to boot when some of the
memblock regions that the host is faulting in are not page-aligned
- Inject some sanity in the NV stage-2 walker by checking the limits
against the advertised PA size, and correctly report the resulting
faults
PPC:
- Fix a PPC e500 build error due to a long-standing wart that was exposed by
the recent conversion to kmalloc_obj(); rip out all the ugliness that
led to the wart.
RISC-V:
- Prevent speculative out-of-bounds access using array_index_nospec()
in APLIC interrupt handling, ONE_REG regiser access, AIA CSR access,
float register access, and PMU counter access
- Fix potential use-after-free issues in kvm_riscv_gstage_get_leaf(),
kvm_riscv_aia_aplic_has_attr(), and kvm_riscv_aia_imsic_has_attr()
- Fix potential null pointer dereference in kvm_riscv_vcpu_aia_rmw_topei()
- Fix off-by-one array access in SBI PMU
- Skip THP support check during dirty logging
- Fix error code returned for Smstateen and Ssaia ONE_REG interface
- Check host Ssaia extension when creating AIA irqchip
x86:
- Fix cases where CPUID mitigation features were incorrectly marked as
available whenever the kernel used scattered feature words for them.
- Validate _all_ GVAs, rather than just the first GVA, when processing
a range of GVAs for Hyper-V's TLB flush hypercalls.
- Fix a brown paper bug in add_atomic_switch_msr().
- Use hlist_for_each_entry_srcu() when traversing mask_notifier_list,
to fix a lockdep warning; KVM doesn't hold RCU, just irq_srcu.
- Ensure AVIC VMCB fields are initialized if the VM has an in-kernel local
APIC (and AVIC is enabled at the module level).
- Update CR8 write interception when AVIC is (de)activated, to fix a bug
where the guest can run in perpetuity with the CR8 intercept enabled.
- Add a quirk to skip the consistency check on FREEZE_IN_SMM, i.e. to allow
L1 hypervisors to set FREEZE_IN_SMM. This reverts (by default) an
unintentional tightening of userspace ABI in 6.17, and provides some
amount of backwards compatibility with hypervisors who want to freeze
PMCs on VM-Entry.
- Validate the VMCS/VMCB on return to a nested guest from SMM, because
either userspace or the guest could stash invalid values in memory
and trigger the processor's consistency checks.
Generic:
- Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from being
unnecessary and confusing, triggered compiler warnings due to
-Wflex-array-member-not-at-end.
- Document that vcpu->mutex is take outside of kvm->slots_lock and
kvm->slots_arch_lock, which is intentional and desirable despite being
rather unintuitive.
Selftests:
- Increase the maximum number of NUMA nodes in the guest_memfd selftest to
64 (from 8).

Pull kvm fixes from Paolo Bonzini:
"Quite a large pull request, partly due to skipping last week and
therefore having material from ~all submaintainers in this one. About
a fourth of it is a new selftest, and a couple more changes are large
in number of files touched (fixing a -Wflex-array-member-not-at-end
compiler warning) or lines changed (reformatting of a table in the API
documentation, thanks rST).

-Wflex-array-member-not-at-end.
- Document that vcpu->mutex is take outside of kvm->slots_lock and
kvm->slots_arch_lock, which is intentional and desirable despite being
rather unintuitive.

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.

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.

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 |

mshv: Add SMT_ENABLED_GUEST partition creation flag
Add support for HV_PARTITION_CREATION_FLAG_SMT_ENABLED_GUEST to allow userspace VMMs to enable SMT for guest partitions. Expose this via new MSHV_PT_BIT_SMT_ENABLED_GUEST flag in the UAPI. Without this flag, the hypervisor schedules guest VPs incorrectly, causing SMT unusable. Signed-off-by: Anatol Belski <anbelski@linux.microsoft.com> Signed-off-by: Wei Liu <wei.liu@kernel.org> |

Pull more io_uring updates from Jens Axboe:
"This is a mix of cleanups and fixes. No major fixes in here, just a
bunch of little fixes. Some of them marked for stable as it fixes
behavioral issues
- Fix an issue with SOCKET_URING_OP_SETSOCKOPT for netlink sockets,
due to a too restrictive check on it having an ioctl handler
- Remove a redundant SQPOLL check in ring creation
- Kill dead accounting for zero-copy send, which doesn't use ->buf
or ->len post the initial setup
- Fix missing clamp of the allocation hint, which could cause
allocations to fall outside of the range the application asked
for. Still within the allowed limits.
- Fix for IORING_OP_PIPE's handling of direct descriptors
- Tweak to the API for the newly added BPF filters, making them
more future proof in terms of how applications deal with them
- A few fixes for zcrx, fixing a few error handling conditions
- Fix for zcrx request flag checking
- Add support for querying the zcrx page size
- Improve the NO_SQARRAY static branch inc/dec, avoiding busy
conditions causing too much traffic
- Various little cleanups"

include: uapi: netfilter_bridge.h: Cover for musl libc
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"
* tag 'vfs-7.0-rc1.misc.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:

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 |

NFSD 7.0 Release Notes
Neil Brown and Jeff Layton contributed a dynamic thread pool sizing mechanism for NFSD. The sunrpc layer now tracks minimum and maximum thread counts per pool, and NFSD adjusts running thread counts based on workload: idle threads exit after a timeout when the pool exceeds its minimum, and new threads spawn automatically when all threads are busy. Administrators control this behavior via the nfsdctl netlink interface. Rick Macklem, FreeBSD NFS maintainer, generously contributed server- side support for the POSIX ACL extension to NFSv4, as specified in draft-ietf-nfsv4-posix-acls. This extension allows NFSv4 clients to get and set POSIX access and default ACLs using native NFSv4 operations, eliminating the need for sideband protocols. The feature is gated by a Kconfig option since the IETF draft has not yet been ratified. Chuck Lever delivered numerous improvements to the xdrgen tool. Error reporting now covers parsing, AST transformation, and invalid declarations. Generated enum decoders validate incoming values against valid enumerator lists. New features include pass-through line support for embedding C directives in XDR specifications, 16-bit integer types, and program number definitions. Several code generation issues were also addressed.

The sunrpc layer now tracks minimum and maximum thread counts per pool, and NFSD adjusts running thread counts based on workload: idle threads exit after a timeout when the pool exceeds its minimum, and new threads spawn automatically when all threads are busy. Administrators control this behavior via the nfsdctl netlink interface. Rick Macklem, FreeBSD NFS maintainer, generously contributed server- side support for the POSIX ACL extension to NFSv4, as specified in draft-ietf-nfsv4-posix-acls. This extension allows NFSv4 clients to get and set POSIX access and default ACLs using native NFSv4 operations, eliminating the need for sideband protocols. The feature is gated by a Kconfig option since the IETF draft has not yet been ratified. Chuck Lever delivered numerous improvements to the xdrgen tool. Error reporting now covers parsing, AST transformation, and invalid declarations. Generated enum decoders validate incoming values against valid enumerator lists. New features include pass-through line support for embedding C directives in XDR specifications, 16-bit integer types, and program number definitions.

Networking changes for 7.0
Core & protocols
----------------
- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls for
small helper and stack canary overhead in the fast-path. This
generates better and faster code with very small or no text size
increases, as in many cases the call generated more code than the
actual inlined helper.
- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.
- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage by
up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the RX
path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without the
HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified, aligning
IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the rate
shaper of sch_cake across multiple CPUs, while still enforcing a
single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations that
are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information, saving
cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most protocols,
avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies between
the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented
optimizations.
- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes back
online.
Driver API
----------
- Support for switching the working mode (automatic vs manual) of a DPLL
device via netlink.
- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.

generalize polarity inversion requirements for differential signaling.
- Add helper to create, prepare and enable managed clocks.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Don't try to enable Extended Tags on VFs since that bit is Reserved
and causes misleading log messages (Håkon Bugge)
- Initialize Endpoint Read Completion Boundary to match Root Port,
regardless of ACPI _HPX (Håkon Bugge)
- Apply _HPX PCIe Setting Record only to AER configuration, and only
when OS owns PCIe hotplug but not AER, to avoid clobbering Extended
Tag and Relaxed Ordering settings (Håkon Bugge)
Resource management:
- Move CardBus code to setup-cardbus.c and only build it when
CONFIG_CARDBUS is set (Ilpo Järvinen)
- Fix bridge window alignment with optional resources, where
additional alignment requirement was previously lost (Ilpo
Järvinen)
- Stop over-estimating bridge window size since they are now assigned
without any gaps between them (Ilpo Järvinen)
- Increase resource MAX_IORES_LEVEL to avoid /proc/iomem flattening
for nested bridges and endpoints (Ilpo Järvinen)
- Add pbus_mem_size_optional() to handle sizes of optional resources
(SR-IOV VF BARs, expansion ROMs, bridge windows) (Ilpo Järvinen)
- Don't claim disabled bridge windows to avoid spurious claim
failures (Ilpo Järvinen)
Driver binding:
- Fix device reference leak in pcie_port_remove_service() (Uwe
Kleine-König)
- Move pcie_port_bus_match() and pcie_port_bus_type to PCIe-specific
portdrv.c (Uwe Kleine-König)
- Convert portdrv to use pcie_port_bus_type.probe() and .remove()
callbacks so .probe() and .remove() can eventually be removed from
struct device_driver (Uwe Kleine-König)
Error handling:
- Clear stale errors on reporting agents upon probe so they don't
look like recent errors (Lukas Wunner)
- Add generic RAS tracepoint for hotplug events (Shuai Xue)
- Add RAS tracepoint for link speed changes (Shuai Xue)
Power management:
- Avoid redundant delay on transition from D3hot to D3cold if the
device was already in D3hot (Brian Norris)
- Prevent runtime suspend until devices are fully initialized to
avoid saving incompletely configured device state (Brian Norris)
Power control:
- Add power_on/off callbacks with generic signature to pwrseq,
tc9563, and slot drivers so they can be used by pwrctrl core
(Manivannan Sadhasivam)
- Add PCIe M.2 connector support to the slot pwrctrl driver
(Manivannan Sadhasivam)
- Switch to pwrctrl interfaces to create, destroy, and power on/off
devices, calling them from host controller drivers instead of the
PCI core (Manivannan Sadhasivam)
- Drop qcom .assert_perst() callbacks since this is now done by the
controller driver instead of the pwrctrl driver (Manivannan
Sadhasivam)
Virtualization:
- Remove an incorrect unlock in pci_slot_trylock() error handling
(Jinhui Guo)
- Lock the bridge device for slot reset (Keith Busch)
- Enable ACS after IOMMU configuration on OF platforms so ACS is
enabled an all devices; previously the first device enumerated
(typically a Root Port) didn't have ACS enabled (Manivannan
Sadhasivam)
- Disable ACS Source Validation for IDT 0x80b5 and 0x8090 switches to
work around hardware erratum; previously ACS SV was only
temporarily disabled, which worked for enumeration but not after
reset (Manivannan Sadhasivam)
Peer-to-peer DMA:
- Release per-CPU pgmap ref when vm_insert_page() fails to avoid hang
when removing the PCI device (Hou Tao)
- Remove incorrect p2pmem_alloc_mmap() warning about page refcount
(Hou Tao)
Endpoint framework:
- Add configfs sub-groups synchronously to avoid NULL pointer
dereference when racing with removal (Liu Song)
- Fix swapped parameters in pci_{primary/secondary}_epc_epf_unlink()
functions (Manikanta Maddireddy)
ASPEED PCIe controller driver:
- Add ASPEED Root Complex DT binding and driver (Jacky Chou)
Freescale i.MX6 PCIe controller driver:
- Add DT binding and driver support for an optional external refclock
in addition to the refclock from the internal PLL (Richard Zhu)
- Fix CLKREQ# control so host asserts it during enumeration and
Endpoints can use it afterwards to exit the L1.2 link state
(Richard Zhu)
NVIDIA Tegra PCIe controller driver:
- Export irq_domain_free_irqs() to allow PCI/MSI drivers that tear
down MSI domains to be built as modules (Aaron Kling)
- Allow pci-tegra to be built as a module (Aaron Kling)
NVIDIA Tegra194 PCIe controller driver:
- Relax Kconfig so tegra194 can be built for platforms beyond
Tegra194 (Vidya Sagar)
Qualcomm PCIe controller driver:
- Merge SC8180x DT binding into SM8150 (Krzysztof Kozlowski)
- Move SDX55, SDM845, QCS404, IPQ5018, IPQ6018, IPQ8074 Gen3,
IPQ8074, IPQ4019, IPQ9574, APQ8064, MSM8996, APQ8084 to dedicated
schema (Krzysztof Kozlowski)
- Add DT binding and driver support for SA8255p Endpoint being
configured by firmware (Mrinmay Sarkar)
- Parse PERST# from all PCIe bridge nodes for future platforms that
will have PERST# in Switch Downstream Ports as well as in Root
Ports (Manivannan Sadhasivam)
Renesas RZ/G3S PCIe controller driver:
- Use pci_generic_config_write() since the writability provided by
the custom wrapper is unnecessary (Claudiu Beznea)
SOPHGO PCIe controller driver:
- Disable ASPM L0s and L1 on Sophgo 2044 PCIe Root Ports (Inochi
Amaoto)
Synopsys DesignWare PCIe controller driver:
- Extend PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() to return a
pointer to the preceding Capability, to allow removal of
Capabilities that are advertised but not fully implemented (Qiang
Yu)
- Remove MSI and MSI-X Capabilities in platforms that can't support
them, so the PCI core automatically falls back to INTx (Qiang Yu)
- Add ASPM L1.1 and L1.2 Substates context to debugfs ltssm_status
for drivers that support this (Shawn Lin)
- Skip PME_Turn_Off broadcast and L2/L3 transition during suspend if
link is not up to avoid an unnecessary timeout (Manivannan
Sadhasivam)
- Revert dw-rockchip, qcom, and DWC core changes that used link-up
IRQs to trigger enumeration instead of waiting for link to be up
because the PCI core doesn't allocate bus number space for
hierarchies that might be attached (Niklas Cassel)
- Make endpoint iATU entry for MSI permanent instead of programming
it dynamically, which is slow and racy with respect to other
concurrent traffic, e.g., eDMA (Koichiro Den)
- Use iMSI-RX MSI target address when possible to fix endpoints using
32-bit MSI (Shawn Lin)
- Allow DWC host controller driver probe to continue if device is not
found or found but inactive; only fail when there's an error with
the link (Manivannan Sadhasivam)
- For controllers like NXP i.MX6QP and i.MX7D, where LTSSM registers
are not accessible after PME_Turn_Off, simply wait 10ms instead of
polling for L2/L3 Ready (Richard Zhu)
- Use multiple iATU entries to map large bridge windows and DMA
ranges when necessary instead of failing (Samuel Holland)
- Add EPC dynamic_inbound_mapping feature bit for Endpoint
Controllers that can update BAR inbound address translation without
requiring EPF driver to clear/reset the BAR first, and advertise it
for DWC-based Endpoints (Koichiro Den)
- Add EPC subrange_mapping feature bit for Endpoint Controllers that
can map multiple independent inbound regions in a single BAR,
implement subrange mapping, advertise it for DWC-based Endpoints,
and add Endpoint selftests for it (Koichiro Den)
- Make resizable BARs work for Endpoint multi-PF configurations;
previously it only worked for PF 0 (Aksh Garg)
- Fix Endpoint non-PF 0 support for BAR configuration, ATU mappings,
and Address Match Mode (Aksh Garg)
- Set up iATU when ECAM is enabled; previously IO and MEM outbound
windows weren't programmed, and ECAM-related iATU entries weren't
restored after suspend/resume, so config accesses failed (Krishna
Chaitanya Chundru)
Miscellaneous:
- Use system_percpu_wq and WQ_PERCPU to explicitly request per-CPU
work so WQ_UNBOUND can eventually be removed (Marco Crivellari)"

* Update gendwarfksyms documentation with required dependencies (Jihan
LIN)
* Reject invalid LLVM= values to avoid unintentionally falling back to
system toolchain (Thomas Weißschuh)
* Add a script to help run the kernel build process in a container for
consistent environments and testing (Guillaume Tucker)
* Simplify kallsyms by getting rid of the relative base (Ard Biesheuvel)
* Performance and usability improvements to scripts/make_fit.py (Simon
Glass)
* Minor various clean ups and fixes
Kconfig changes
===============
* Move XPM icons to individual files, clearing up GTK deprecation
warnings (Rostislav Krasny)
* Support
depends on FOO if BAR
as syntactic sugar for
depends on FOO || !BAR' (Nicolas Pitre, Graham Roff)
* Refactor merge_config.sh to use awk over shell/sed/grep, dramatically
speeding up processing large number of config fragments (Anders
Roxell, Mikko Rapeli)
