Protocols
---------
- Implement support for TCP probing the peer being under memory
pressure.
- Remove hard coded limitation on IPv6 specific info placement
inside the socket struct.
- Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated
per socket scaling factor.
- Scaling-up the IPv6 expired route GC via a separated list of
expiring routes.
- In-kernel support for the TLS alert protocol.
- Better support for UDP reuseport with connected sockets.
- Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
header size.

Driver API
----------
- Page pool optimizations, to improve data locality and cache usage.
- Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need
for raw ioctl() handling in drivers.
- Simplify genetlink dump operations (doit/dumpit) providing them
the common information already populated in struct genl_info.
- Extend and use the yaml devlink specs to [re]generate the split ops.
- Introduce devlink selective dumps, to allow SF filtering SF based on
handle and other attributes.
- Add yaml netlink spec for netlink-raw families, allow route, link and
address related queries via the ynl tool.
- Remove phylink legacy mode support.
- Support offload LED blinking to phy.

Developers can easily execute several tests on different devices
by just pushing their branch to their fork in a repository hosted
on gitlab.freedesktop.org which has an infrastructure to run jobs
in several runners and farms with different devices.
There are also other automated tools that uprev dependencies,
monitor the infra, and so on that are already used by the Mesa
project, and we can reuse them too.
Also, store expectations about what the DRM drivers are supposed
to pass in the IGT test suite. By storing the test expectations
along with the code, we can make sure both stay in sync with each
other so we can know when a code change breaks those expectations.
Also, include a configuration file that points to the out-of-tree
CI scripts.
This will allow all contributors to drm to reuse the infrastructure
already in gitlab.freedesktop.org to test the driver on several
generations of the hardware.

There's been quite a lot of generic activity here, but more
administrative than featuers. We also have a bunch of new drivers,
including one that's part of a MFD so we pulled in the core parts of
that:
- Lots of work from both Yang Yingliang and Andy Shevchenko on moving
to host/device/controller based terminology for devices.
- QuadSPI SPI support for Allwinner sun6i.
- New device support Cirrus Logic CS43L43, Longsoon, Qualcomm GENI
QuPv3 and StarFive JH7110 QSPI.

In terms of lines, most changes this time are on the pinned-init API
and infrastructure. While we have a Rust version upgrade, and thus a
bunch of changes from the vendored 'alloc' crate as usual, this time
those do not account for many lines.
Toolchain and infrastructure:
- Upgrade to Rust 1.71.1. This is the second such upgrade, which is a
smaller jump compared to the last time.
This version allows us to remove the '__rust_*' allocator functions
-- the compiler now generates them as expected, thus now our
'KernelAllocator' is used.
It also introduces the 'offset_of!' macro in the standard library
(as an unstable feature) which we will need soon. So far, we were
using a declarative macro as a prerequisite in some not-yet-landed
patch series, which did not support sub-fields (i.e. nested structs):
#[repr(C)]
struct S {
a: u16,
b: (u8, u8),
}
assert_eq!(offset_of!(S, b.1), 3);
- Upgrade to bindgen 0.65.1. This is the first time we upgrade its
version.
Given it is a fairly big jump, it comes with a fair number of
improvements/changes that affect us, such as a fix needed to support
LLVM 16 as well as proper support for '__noreturn' C functions, which
are now mapped to return the '!' type in Rust:
void __noreturn f(void); // C
pub fn f() -> !; // Rust
- 'scripts/rust_is_available.sh' improvements and fixes.
This series takes care of all the issues known so far and adds a few
new checks to cover for even more cases, plus adds some more help
texts. All this together will hopefully make problematic setups
easier to identify and to be solved by users building the kernel.
In addition, it adds a test suite which covers all branches of the
shell script, as well as tests for the issues found so far.
- Support rust-analyzer for out-of-tree modules too.
- Give 'cfg's to rust-analyzer for the 'core' and 'alloc' crates.
- Drop 'scripts/is_rust_module.sh' since it is not needed anymore.
Macros crate:
- New 'paste!' proc macro.
This macro is a more flexible version of 'concat_idents!': it allows
the resulting identifier to be used to declare new items and it
allows to transform the identifiers before concatenating them, e.g.
let x_1 = 42;
paste!(let [<x _2>] = [<x _1>];);
assert!(x_1 == x_2);
The macro is then used for several of the pinned-init API changes in
this pull.
Pinned-init API:
- Make '#[pin_data]' compatible with conditional compilation of fields,
allowing to write code like:
#[pin_data]
pub struct Foo {
#[cfg(CONFIG_BAR)]
a: Bar,
#[cfg(not(CONFIG_BAR))]
a: Baz,
}
- New '#[derive(Zeroable)]' proc macro for the 'Zeroable' trait, which
allows 'unsafe' implementations for structs where every field
implements the 'Zeroable' trait, e.g.:
#[derive(Zeroable)]
pub struct DriverData {
id: i64,
buf_ptr: *mut u8,
len: usize,
}
- Add '..Zeroable::zeroed()' syntax to the 'pin_init!' macro for
zeroing all other fields, e.g.:
pin_init!(Buf {
buf: [1; 64],
..Zeroable::zeroed()
});
- New '{,pin_}init_array_from_fn()' functions to create array
initializers given a generator function, e.g.:
let b: Box<[usize; 1_000]> = Box::init::<Error>(
init_array_from_fn(|i| i)
).unwrap();
assert_eq!(b.len(), 1_000);
assert_eq!(b[123], 123);
- New '{,pin_}chain' methods for '{,Pin}Init<T, E>' that allow to
execute a closure on the value directly after initialization, e.g.:
let foo = init!(Foo {
buf <- init::zeroed()
}).chain(|foo| {
foo.setup();
Ok(())
});
- Support arbitrary paths in init macros, instead of just identifiers
and generic types.
- Implement the 'Zeroable' trait for the 'UnsafeCell<T>' and
'Opaque<T>' types.
- Make initializer values inaccessible after initialization.
- Make guards in the init macros hygienic.
'allocator' module:
- Use 'krealloc_aligned()' in 'KernelAllocator::alloc' preventing
misaligned allocations when the Rust 1.71.1 upgrade is applied later
in this pull.
The equivalent fix for the previous compiler version (where
'KernelAllocator' is not yet used) was merged into 6.5 already,
which added the 'krealloc_aligned()' function used here.
- Implement 'KernelAllocator::{realloc, alloc_zeroed}' for performance,
using 'krealloc_aligned()' too, which forwards the call to the C API.
'types' module:
- Make 'Opaque' be '!Unpin', removing the need to add a 'PhantomPinned'
field to Rust structs that contain C structs which must not be moved.
- Make 'Opaque' use 'UnsafeCell' as the outer type, rather than inner.
Documentation:
- Suggest obtaining the source code of the Rust's 'core' library using
the tarball instead of the repository.
MAINTAINERS:
- Andreas and Alice, from Samsung and Google respectively, are joining
as reviewers of the "RUST" entry.
As well as a few other minor changes and cleanups.

setups easier to identify and to be solved by users building the
kernel.
In addition, it adds a test suite which covers all branches of the
shell script, as well as tests for the issues found so far.
- Support rust-analyzer for out-of-tree modules too.
- Give 'cfg's to rust-analyzer for the 'core' and 'alloc' crates.
- Drop 'scripts/is_rust_module.sh' since it is not needed anymore.
Macros crate:
- New 'paste!' proc macro.
This macro is a more flexible version of 'concat_idents!': it
allows the resulting identifier to be used to declare new items and
it allows to transform the identifiers before concatenating them,
e.g.
let x_1 = 42;
paste!(let [<x _2>] = [<x _1>];);
assert!(x_1 == x_2);
The macro is then used for several of the pinned-init API changes
in this pull.
Pinned-init API:
- Make '#[pin_data]' compatible with conditional compilation of
fields, allowing to write code like:
#[pin_data]
pub struct Foo {
#[cfg(CONFIG_BAR)]
a: Bar,
#[cfg(not(CONFIG_BAR))]
a: Baz,
}
- New '#[derive(Zeroable)]' proc macro for the 'Zeroable' trait,
which allows 'unsafe' implementations for structs where every field
implements the 'Zeroable' trait, e.g.:
#[derive(Zeroable)]
pub struct DriverData {
id: i64,
buf_ptr: *mut u8,
len: usize,
}
- Add '..Zeroable::zeroed()' syntax to the 'pin_init!' macro for
zeroing all other fields, e.g.:
pin_init!(Buf {
buf: [1; 64],
..Zeroable::zeroed()
});
- New '{,pin_}init_array_from_fn()' functions to create array
initializers given a generator function, e.g.:
let b: Box<[usize; 1_000]> = Box::init::<Error>(
init_array_from_fn(|i| i)
).unwrap();
assert_eq!(b.len(), 1_000);
assert_eq!(b[123], 123);
- New '{,pin_}chain' methods for '{,Pin}Init<T, E>' that allow to
execute a closure on the value directly after initialization, e.g.:
let foo = init!(Foo {
buf <- init::zeroed()
}).chain(|foo| {
foo.setup();
Ok(())
});
- Support arbitrary paths in init macros, instead of just identifiers
and generic types.
- Implement the 'Zeroable' trait for the 'UnsafeCell<T>' and
'Opaque<T>' types.
- Make initializer values inaccessible after initialization.
- Make guards in the init macros hygienic.
'allocator' module:
- Use 'krealloc_aligned()' in 'KernelAllocator::alloc' preventing
misaligned allocations when the Rust 1.71.1 upgrade is applied
later in this pull.
The equivalent fix for the previous compiler version (where
'KernelAllocator' is not yet used) was merged into 6.5 already,
which added the 'krealloc_aligned()' function used here.
- Implement 'KernelAllocator::{realloc, alloc_zeroed}' for
performance, using 'krealloc_aligned()' too, which forwards the
call to the C API.
'types' module:
- Make 'Opaque' be '!Unpin', removing the need to add a
'PhantomPinned' field to Rust structs that contain C structs which
must not be moved.
- Make 'Opaque' use 'UnsafeCell' as the outer type, rather than
inner.
Documentation:
- Suggest obtaining the source code of the Rust's 'core' library
using the tarball instead of the repository.
MAINTAINERS:
- Andreas and Alice, from Samsung and Google respectively, are
joining as reviewers of the "RUST" entry.

Some platforms may not boot if a device driver doesn't

Add the "pcie-mem" & "cpu-pcie" interconnect path as a required
property to the bindings.

- The biggest change is introduction of a new iteration of the
SCHED_FAIR interactivity code: the EEVDF ("Earliest Eligible Virtual
Deadline First") scheduler.
EEVDF too is a virtual-time scheduler, with two parameters (weight
and relative deadline), compared to CFS that had weight only.
It completely reworks the base scheduler: placement, preemption,
picking -- everything.
LWN.net, as usual, has a terrific writeup about EEVDF:
https://lwn.net/Articles/925371/
Preemption (both tick and wakeup) is driven by testing against
a fresh pick. Because the tree is now effectively an interval
tree, and the selection is no longer the 'leftmost' task,
over-scheduling is less of a problem. A lot of the CFS
heuristics are removed or replaced by more natural latency-space
parameters & constructs.
In terms of expected performance regressions: we'll and can fix
everything where a 'good' workload misbehaves with the new scheduler,
but EEVDF inevitably changes workload scheduling in a binary fashion,
hopefully for the better in the overwhelming majority of cases,
but in some cases it won't, especially in adversarial loads that
got lucky with the previous code, such as some variants of hackbench.
We are trying hard to err on the side of fixing all performance
regressions, but we expect some inevitable post-release iterations
of that process.
- Improve load-balancing on hybrid x86 systems: enable cluster
scheduling (again).
- Improve & fix bandwidth-scheduling on nohz systems.
- Improve bandwidth-throttling.
- Use lock guards to simplify and de-goto-ify control flow.

- Support partial SMT enablement.
So far the sysfs SMT control only allows to toggle between SMT on and
off. That's sufficient for x86 which usually has at max two threads
except for the Xeon PHI platform which has four threads per core.
Though PowerPC has up to 16 threads per core and so far it's only
possible to control the number of enabled threads per core via a
command line option. There is some way to control this at runtime, but
that lacks enforcement and the usability is awkward.
This update expands the sysfs interface and the core infrastructure to
accept numerical values so PowerPC can build SMT runtime control for
partial SMT enablement on top.
The core support has also been provided to the PowerPC maintainers who
added the PowerPC related changes on top.
- Minor cleanups and documentation updates.

Pull CPU hotplug updates from Thomas Gleixner:
"Updates for the CPU hotplug core:
- Support partial SMT enablement.
So far the sysfs SMT control only allows to toggle between SMT on
and off. That's sufficient for x86 which usually has at max two
threads except for the Xeon PHI platform which has four threads per
core
Though PowerPC has up to 16 threads per core and so far it's only
possible to control the number of enabled threads per core via a
command line option. There is some way to control this at runtime,
but that lacks enforcement and the usability is awkward
This update expands the sysfs interface and the core infrastructure
to accept numerical values so PowerPC can build SMT runtime control
for partial SMT enablement on top
The core support has also been provided to the PowerPC maintainers
who added the PowerPC related changes on top
- Minor cleanups and documentation updates"

"We've got some big changes for this release -- I'm very happy to be
landing willy's work to enable large folios for the page cache for
general read and write IOs when the fs can make contiguous space
allocations, and Ritesh's work to track sub-folio dirty state to
eliminate the write amplification problems inherent in using large
folios.
As a bonus, io_uring can now process write completions in the caller's
context instead of bouncing through a workqueue, which should reduce
io latency dramatically. IOWs, XFS should see a nice performance bump
for both IO paths.
Summary:
- Make large writes to the page cache fill sparse parts of the cache

Merge tag 'v6.6-vfs.super' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull superblock updates from Christian Brauner:
"This contains the super rework that was ready for this cycle. The
first part changes the order of how we open block devices and allocate
superblocks, contains various cleanups, simplifications, and a new
mechanism to wait on superblock state changes.
This unblocks work to ultimately limit the number of writers to a
block device. Jan has already scheduled follow-up work that will be
ready for v6.7 and allows us to restrict the number of writers to a
given block device. That series builds on this work right here.
The second part contains filesystem freezing updates.
Overview:
The generic superblock changes are rougly organized as follows
(ignoring additional minor cleanups):
(1) Removal of the bd_super member from struct block_device.
This was a very odd back pointer to struct super_block with
unclear rules. For all relevant places we have other means to get
the same information so just get rid of this.
(2) Simplify rules for superblock cleanup.
Roughly, everything that is allocated during fs_context
initialization and that's stored in fs_context->s_fs_info needs
to be cleaned up by the fs_context->free() implementation before
the superblock allocation function has been called successfully.
After sget_fc() returned fs_context->s_fs_info has been
transferred to sb->s_fs_info at which point sb->kill_sb() if
fully responsible for cleanup. Adhering to these rules means that
cleanup of sb->s_fs_info in fill_super() is to be avoided as it's
brittle and inconsistent.
Cleanup shouldn't be duplicated between sb->put_super() as
sb->put_super() is only called if sb->s_root has been set aka
when the filesystem has been successfully born (SB_BORN). That
complexity should be avoided.
This also means that block devices are to be closed in
sb->kill_sb() instead of sb->put_super(). More details in the
lower section.
(3) Make it possible to lookup or create a superblock before opening
block devices
There's a subtle dependency on (2) as some filesystems did rely
on fill_super() to be called in order to correctly clean up
sb->s_fs_info. All these filesystems have been fixed.
(4) Switch most filesystem to follow the same logic as the generic
mount code now does as outlined in (3).
(5) Use the superblock as the holder of the block device. We can now
easily go back from block device to owning superblock.
(6) Export and extend the generic fs_holder_ops and use them as
holder ops everywhere and remove the filesystem specific holder
ops.
(7) Call from the block layer up into the filesystem layer when the
block device is removed, allowing to shut down the filesystem
without risk of deadlocks.
(8) Get rid of get_super().
We can now easily go back from the block device to owning
superblock and can call up from the block layer into the
filesystem layer when the device is removed. So no need to wade
through all registered superblock to find the owning superblock
anymore"

"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual filesystems.
Features:
- Block mode changes on symlinks and rectify our broken semantics
- Report file modifications via fsnotify() for splice
- Allow specifying an explicit timeout for the "rootwait" kernel
command line option. This allows to timeout and reboot instead of
always waiting indefinitely for the root device to show up
- Use synchronous fput for the close system call
Cleanups:
- Get rid of open-coded lockdep workarounds for async io submitters
and replace it all with a single consolidated helper
- Simplify epoll allocation helper
- Convert simple_write_begin and simple_write_end to use a folio
- Convert page_cache_pipe_buf_confirm() to use a folio
- Simplify __range_close to avoid pointless locking
- Disable per-cpu buffer head cache for isolated cpus
- Port ecryptfs to kmap_local_page() api
- Remove redundant initialization of pointer buf in pipe code
- Unexport the d_genocide() function which is only used within core
vfs
- Replace printk(KERN_ERR) and WARN_ON() with WARN()
Fixes:
- Fix various kernel-doc issues
- Fix refcount underflow for eventfds when used as EFD_SEMAPHORE
- Fix a mainly theoretical issue in devpts
- Check the return value of __getblk() in reiserfs
- Fix a racy assert in i_readcount_dec

quota infrastructure is added to support it and a new QFMT_SHMEM
uapi option is exposed.
This offers user and group quotas to tmpfs (project quotas will be
added later). Similar to other filesystems tmpfs quota are not
supported within user namespaces yet.
- Add support for user xattrs. While tmpfs already supports security
xattrs (security.*) and POSIX ACLs for a long time it lacked
support for user xattrs (user.*). With this pull request tmpfs will
be able to support a limited number of user xattrs.
This is accompanied by a fix (see below) to limit persistent simple
xattr allocations.
- Add support for stable directory offsets. Currently tmpfs relies on
the libfs provided cursor-based mechanism for readdir. This causes
issues when a tmpfs filesystem is exported via NFS.
NFS clients do not open directories. Instead, each server-side
readdir operation opens the directory, reads it, and then closes
it. Since the cursor state for that directory is associated with
the opened file it is discarded after each readdir operation. Such
directory offsets are not just cached by NFS clients but also
various userspace libraries based on these clients.
As it stands there is no way to invalidate the caches when
directory offsets have changed and the whole application depends on
unchanging directory offsets.
At LSFMM we discussed how to solve this problem and decided to
support stable directory offsets. libfs now allows filesystems like
tmpfs to use an xarrary to map a directory offset to a dentry. This
mechanism is currently only used by tmpfs but can be supported by
others as well.
Fixes
=====
- Change persistent simple xattrs allocations in libfs from
GFP_KERNEL to GPF_KERNEL_ACCOUNT so they're subject to memory
cgroup limits. Since this is a change to libfs it affects both
tmpfs and kernfs.
- Correctly verify {g,u}id mount options.
A new filesystem context is created via fsopen() which records the
namespace that becomes the owning namespace of the superblock when
fsconfig(FSCONFIG_CMD_CREATE) is called for filesystems that are
mountable in namespaces. However, fsconfig() calls can occur in a
namespace different from the namespace where fsopen() has been
called.
Currently, when fsconfig() is called to set {g,u}id mount options
the requested {g,u}id is mapped into a k{g,u}id according to the
namespace where fsconfig() was called from. The resulting k{g,u}id
is not guaranteed to be resolvable in the namespace of the
filesystem (the one that fsopen() was called in).
This means it's possible for an unprivileged user to create files
owned by any group in a tmpfs mount since it's possible to set the
setid bits on the tmpfs directory.
The contract for {g,u}id mount options and {g,u}id values in
general set from userspace has always been that they are translated
according to the caller's idmapping. In so far, tmpfs has been
doing the correct thing. But since tmpfs is mountable in
unprivileged contexts it is also necessary to verify that the
resulting {k,g}uid is representable in the namespace of the
superblock to avoid such bugs.
The new mount api's cross-namespace delegation abilities are
already widely used. Having talked to a bunch of userspace this is
the most faithful solution with minimal regression risks"
