- Error module: fix the description for 'ECHILD' and fix Markdown
style nit
- Code docs: fix logo replacement
- Docs: update docs output path

The Rust code documentation output path moved from `rust/doc` to
`Documentation/output/rust/rustdoc`. The `make cleandocs` target
takes care of cleaning it now since it is integrated with the rest
of the documentation.
Thus remove the old reference.

Currently the Kconfig fragments in kernel/configs and arch/*/configs
that aren't used internally aren't discoverable through "make help",
which consists of hard-coded lists of config fragments. Instead, list
all the fragment targets that have a "# Help: " comment prefix so the
targets can be generated dynamically.
Add logic to the Makefile to search for and display the fragment and
comment. Add comments to fragments that are intended to be direct targets.

The modules_sign target is currently only available for in-tree modules,
but it actually works for external modules as well.
Move the modules_sign rule to the common part.

Pull rust updates from Miguel Ojeda:
"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.

This reverts the old commit "kbuild: Introduce source symlink in
/lib/modules/.../". [1]
The current Kbuild does not require $(MODLIB)/source. If the kernel was
built in a separate output directory, $(MODLIB)/build/Makefile wraps
the Makefile in the source tree. It is enough for building external
modules.

Move the depmod rule to scripts/Makefile.modinst and run it only when
$(modules_sign_only) is empty.

Warning options are enabled and disabled in inconsistent ways and
inconsistent locations. Start rearranging those by moving all options
into Makefile.extrawarn.
This should not change any behavior, but makes sure we can group them
in a way that ensures that each warning that got temporarily disabled
is turned back on at an appropriate W=1 level later on.

Introduced in Rust 1.69.0 [1], this lint prevents forgetting to set
the C ABI when using `#[no_mangle]` (or thinking it is implied).
For instance, it would have prevented the issue [2] fixed by commit
c682e4c37d2b ("rust: kernel: Mark rust_fmt_argument as extern "C"").
error: `#[no_mangle]` set on a function with the default (`Rust`) ABI

Thus enable it.
In rare cases, we may need to use the Rust ABI even with `#[no_mangle]`
(e.g. one case, before 1.71.0, would have been the `__rust_*`
functions). In those cases, we would need to `#[allow(...)]` the lint,
since using `extern "Rust"` explicitly (as the compiler suggests)
currently gets overwritten by `rustfmt` [3].

The -v option is passed when this script is invoked from Makefile,
but not when invoked from Kconfig.
As you can see in scripts/Kconfig.include, the 'success' macro suppresses
stdout and stderr anyway, so this script does not need to be quiet.

Adds support for out-of-tree rust modules to use the `rust-analyzer`
make target to generate the rust-project.json file.
The change involves adding an optional parameter `external_src` to the
`generate_rust_analyzer.py` which expects the path to the out-of-tree
module's source directory. When this parameter is passed, I have chosen
not to add the non-core modules (samples and drivers) into the result
since these are not expected to be used in third party modules. Related
changes are also made to the Makefile and rust/Makefile allowing the
`rust-analyzer` target to be used for out-of-tree modules as well.

There are some cases where we want to run a command with the same
environment variables as Kbuild uses. For example, 'make coccicheck'
invokes scripts/coccicheck from the top Makefile so that the script can
reference to ${LINUXINCLUDE}, ${KBUILD_EXTMOD}, etc. The top Makefile
defines several phony targets that run a script.
We do it also for an internally used script, which results in a somewhat
complex call graph.
One example:
debian/rules binary-arch
-> make intdeb-pkg
-> scripts/package/builddeb
It is also tedious to add a dedicated target like 'intdeb-pkg' for each
use case.
Add a generic target 'run-command' to run an arbitrary command in an
environment with all Kbuild variables set.
The usage is:
$ make run-command KBUILD_RUN_COMMAND=<command>
The concept is similar to:
$ dpkg-architecture -c <command>
This executes <command> in an environment which has all DEB_* variables
defined.
Convert the existing 'make intdeb-pkg'.
Another possible usage is to interrogate a Make variable.
$ make run-command KBUILD_RUN_COMMAND='echo $(KBUILD_CFLAGS)'
might be useful to see KBUILD_CFLAGS set by the top Makefile.

This diagnostic checks whether there is a type mismatch when
converting enums (assign an enum of type A to an enum of type B, for
example) and it caught a legit issue recently. The reason it didn't show
is because that warning is enabled only with -Wextra with GCC. Clang,
however, enables it by default.
GCC folks were considering enabling it by default but it was too noisy
back then:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78736
Now that due to clang all those warnings have been fixed, enable it with
GCC too.

crossbuilds.
