devres: add free_node callback to struct devres_node
Currently, there are three "subclasses" of struct devres_node, which are
struct devres, struct devres_group, struct devres_action.
release_nodes(), which only knows about the base struct devres_node,
assumes that for all "subclasses" struct devres_node is the first member
in the structure and calls kfree() on struct devres_node.
While this technically works, we can still improve semantical
correctness and type safety with a corresponding free_node() callback.
Additionally, we will need this callback soon in the Rust Devres code,
to allocate and free the required memory on the Rust side.
devres: don't require ARCH_DMA_MINALIGN for devres actions
Currently, devres actions are allocated with devres_alloc(), which
allocates a struct devres with a flexible array member for the actual
data of the resource. The flexible array member is aligned to
ARCH_DMA_MINALIGN, which is wasteful for devres actions that only need
to store a struct action_devres.
Introduce struct devres_action to handle devres actions separately from
struct devres, analogous to what we do for struct devres_group.
Speaking of which, without this patch struct devres_group is treated as
struct devres in release_nodes(). While this is not an actual bug, as
release callbacks for devres nodes in struct devres_group are empty
functions anyways, it is a bit messy and can be confusing.
(Note that besides devres actions, the Rust devres code will also make
use of this. The Rust compiler can figure out the correct alignment of T
in Devres<T> itself, i.e. no need to force a minimum alignment.)

Register abstraction and I/O infrastructure improvements
Introduce the register!() macro to define type-safe I/O register
accesses. Refactor the IoCapable trait into a functional trait, which
simplifies I/O backends and removes the need for overloaded Io methods.
rust: io: introduce `write_reg` and `LocatedRegister`
Some I/O types, like fixed address registers, carry their location
alongside their values. For these types, the regular `Io::write` method
can lead into repeating the location information twice: once to provide
the location itself, another time to build the value.
We are also considering supporting making all register values carry
their full location information for convenience and safety.
Add a new `Io::write_reg` method that takes a single argument
implementing `LocatedRegister`, a trait that decomposes implementors
into a `(location, value)` tuple. This allows write operations on fixed
offset registers to be done while specifying their name only once.
rust: io: use generic read/write accessors for primitive accesses
By providing the required `IoLoc` implementations on `usize`, we can
leverage the generic accessors and reduce the number of unsafe blocks in
the module.
This also allows us to directly call the generic `read/write/update`
methods with primitive types, so add examples illustrating this.
rust: io: add IoLoc type and generic I/O accessors
I/O accesses are defined by the following properties:
- An I/O location, which consists of a start address, a width, and a
type to interpret the read value as,
- A value, which is returned for reads or provided for writes.
Introduce the `IoLoc` trait, which allows implementing types to fully
specify an I/O location.
This allows I/O operations to be made generic through the new `read` and
`write` methods.
This design will allow us to factorize the I/O code working with
primitives, and to introduce ways to perform I/O with a higher degree of
control through register types.

There is a need to access the inner value of a `Bounded` in const

rust: io: provide Mmio relaxed ops through a wrapper type
Relaxed I/O accessors for `Mmio` are currently implemented as an extra
set of methods that mirror the ones defined in `Io`, but with the
`_relaxed` suffix.
This makes these methods impossible to use with generic code, which is a
highly plausible proposition now that we have the `Io` trait.
Address this by adding a new `RelaxedMmio` wrapper type for `Mmio` that
provides its own `IoCapable` implementations relying on the relaxed C
accessors. This makes it possible to use relaxed operations on a `Mmio`
simply by wrapping it, and to use `RelaxedMmio` in code generic against
`Io`.

`IoCapable<T>` is currently used as a marker trait to signal that the
methods of the `Io` trait corresponding to `T` have been overridden by
the implementor (the default implementations triggering a build-time
error).
This goes against the DRY principle and separates the signaling of the
capability from its implementation, making it possible to forget a step
while implementing a new `Io`.
Another undesirable side-effect is that it makes the implementation of
I/O backends boilerplate-y and convoluted: currently this is done using
two levels of imbricated macros that generate unsafe code.
Fix these issues by turning `IoCapable` into a functional trait that
includes the raw implementation of the I/O access for `T` using
unsafe methods that work with an arbitrary address.
This allows us to turn the default methods of `Io` into regular methods
that check the passed offset, turn it into an address, and call into the
corresponding `IoCapable` functions, removing the need to overload them
at all.
`IoCapable` must still be implemented for all supported primitive types,
which is still done more concisely using a macro, but this macro becomes
much simpler and does not require calling into another one.

"Quite a large pull request, partly due to skipping last week and

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).
But who am I kidding---it's a lot of commits and there are a lot of
bugs being fixed here, some of them on the nastier side like the
RISC-V ones.
ARM:
- Correctly handle deactivation 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

snprintf() returns the number of characters that would have been
written excluding the NUL terminator. Output is truncated when the
return value is >= the buffer size, not just > the buffer size.
When ret == size, the current code takes the non-truncated path,
advancing buf by ret and reducing size to 0. This is wrong because
the output was actually truncated (the last character was replaced by
NUL). Fix by using >= so the truncation path is taken correctly.

lib/bootconfig: check bounds before writing in __xbc_open_brace()
The bounds check for brace_index happens after the array write.
While the current call pattern prevents an actual out-of-bounds
access (the previous call would have returned an error), the
write-before-check pattern is fragile and would become a real
out-of-bounds write if the error return were ever not propagated.
Move the bounds check before the array write so the function is
self-contained and safe regardless of caller behavior.

powerpc/iommu: fix lockdep warning during PCI enumeration
Commit a75b2be249d6 ("iommu: Add iommu_driver_get_domain_for_dev()
helper") introduced iommu_driver_get_domain_for_dev() for driver
code paths that hold iommu_group->mutex while attaching a device
to an IOMMU domain.
The same commit also added a lockdep assertion in
iommu_get_domain_for_dev() to ensure that callers do not hold
iommu_group->mutex when invoking it.
On powerpc platforms, when PCI device ownership is switched from
BLOCKED to the PLATFORM domain, the attach callback
spapr_tce_platform_iommu_attach_dev() still calls
iommu_get_domain_for_dev(). This happens while iommu_group->mutex
is held during domain switching, which triggers the lockdep warning
below during PCI enumeration:
Fix this by using iommu_driver_get_domain_for_dev() instead of
iommu_get_domain_for_dev() in spapr_tce_platform_iommu_attach_dev(),
which is the appropriate helper for callers holding the group mutex.

__xbc_open_brace() pushes entries with post-increment
(open_brace[brace_index++]), so brace_index always points one past
the last valid entry. xbc_verify_tree() reads open_brace[brace_index]
to report which brace is unclosed, but this is one past the last
pushed entry and contains stale/zero data, causing the error message
to reference the wrong node.
Use open_brace[brace_index - 1] to correctly identify the unclosed
brace. brace_index is known to be > 0 here since we are inside the
if (brace_index) guard.

kernfs: Send IN_DELETE_SELF and IN_IGNORED
Currently some kernfs files (e.g. cgroup.events, memory.events) support
inotify watches for IN_MODIFY, but unlike with regular filesystems, they
do not receive IN_DELETE_SELF or IN_IGNORED events when they are
removed. This means inotify watches persist after file deletion until
the process exits and the inotify file descriptor is cleaned up, or
until inotify_rm_watch is called manually.
This creates a problem for processes monitoring cgroups. For example, a
service monitoring memory.events for memory.high breaches needs to know
when a cgroup is removed to clean up its state. Where it's known that a
cgroup is removed when all processes die, without IN_DELETE_SELF the
service must resort to inefficient workarounds such as:
1) Periodically scanning procfs to detect process death (wastes CPU
and is susceptible to PID reuse).
2) Holding a pidfd for every monitored cgroup (can exhaust file
descriptors).
This patch enables IN_DELETE_SELF and IN_IGNORED events for kernfs files
and directories by clearing inode i_nlink values during removal. This
allows VFS to make the necessary fsnotify calls so that userspace
receives the inotify events.
As a result, applications can rely on a single existing watch on a file
of interest (e.g. memory.events) to receive notifications for both
modifications and the eventual removal of the file, as well as automatic
watch descriptor cleanup, simplifying userspace logic and improving
efficiency.
There is gap in this implementation for certain file removals due their
unique nature in kernfs. Directory removals that trigger file removals
occur through vfs_rmdir, which shrinks the dcache and emits fsnotify
events after the rmdir operation; there is no issue here. However kernfs
writes to particular files (e.g. cgroup.subtree_control) can also cause
file removal, but vfs_write does not attempt to emit fsnotify events
after the write operation, even if i_nlink counts are 0. As a usecase
for monitoring this category of file removals is not known, they are
left without having IN_DELETE or IN_DELETE_SELF events generated.
Fanotify recursive monitoring also does not work for kernfs nodes that
do not have inodes attached, as they are created on-demand in kernfs.

kernfs: Don't set_nlink for directories being removed
If a directory is already in the process of removal its i_nlink count
becomes irrelevant because its contents are also about to be removed and
any pending filesystem operations on it or its contents will soon start
to fail. So we can avoid setting it for directories already flagged for
removal.
This avoids a race in the next patch, which adds clearing of the i_nlink
count for kernfs nodes being removed to support inotify delete events.
Use protection from the kernfs_iattr_rwsem to avoid adding more
contention to the kernfs_rwsem for calls to kernfs_refresh_inode.

rust: kbuild: allow `unused_features`
Starting with the upcoming Rust 1.96.0 (to be released 2026-05-28),
`rustc` introduces the new lint `unused_features` [1], which warns [2]:
warning: feature `used_with_arg` is declared but not used
--> <crate attribute>:1:93
|
1 | #![feature(asm_const,asm_goto,arbitrary_self_types,lint_reasons,offset_of_nested,raw_ref_op,used_with_arg)]
| ^^^^^^^^^^^^^
|
= note: `#[warn(unused_features)]` (part of `#[warn(unused)]`) on by default
The original goal of using `-Zcrate-attr` automatically was that there
is a consistent set of features enabled and managed globally for all
Rust kernel code (modulo exceptions like the `rust/` crated).
While we could require crates to enable features manually (even if we
still keep the `-Zallow-features=` list, i.e. removing the `-Zcrate-attr`
list), it is not really worth making all developers worry about it just
for a new lint.
The features are expected to eventually become stable anyway (most already
did), and thus having to remove features in every file that may use them
is not worth it either.
Thus just allow the new lint globally.
The lint actually existed for a long time, which is why `rustc` does
not complain about an unknown lint in the stable versions we support,
but it was "disabled" years ago [3], and now it was made to work again.
For extra context, the new implementation of the lint has already been
improved to avoid linting about features that became stable thanks to
Benno's report and the ensuing discussion [4] [5], but while that helps,
it is still the case that we may have features enabled that are not used
for one reason or another in a particular crate.
