Subject: [GIT PULL] Rust for 6.12
Hi Linus,
This is the next round of the Rust support.
Quite late, but all the commits have been in linux-next for at least a
week (most have been for a few weeks).
This PR is a bit more involved than the usual ones -- the relevant
maintainers were OK with us carrying the patches since there were a few
interdependencies.
Three simple conflicts expected. Please note that akpm and I carried
the same patch ("kasan: simplify and clarify Makefile").
Regarding Rust-related things: you already merged the QR code panic
screen via DRM, the Applied Micro QT2025 PHY driver (with a new `sizes`
module) via netdev, a `k{v,}realloc()` patch via mm and two selftest
config fixes. You have also got a firmware code doc fix via asoc.
Please pull for v6.12 -- thanks!
Cheers,
Miguel

kasan: rust: Add KASAN smoke test via UAF (2024-09-16 18:04:37 +0200)
----------------------------------------------------------------
Rust changes for v6.12
Toolchain and infrastructure:
- Support 'MITIGATION_{RETHUNK,RETPOLINE,SLS}' (which cleans up objtool
warnings), teach objtool about 'noreturn' Rust symbols and mimic
'___ADDRESSABLE()' for 'module_{init,exit}'. With that, we should be
objtool-warning-free, so enable it to run for all Rust object files.
- KASAN (no 'SW_TAGS'), KCFI and shadow call sanitizer support.
- Support 'RUSTC_VERSION', including re-config and re-build on change.
- Split helpers file into several files in a folder, to avoid conflicts
in it. Eventually those files will be moved to the right places with
the new build system. In addition, remove the need to manually export
the symbols defined there, reusing existing machinery for that.
- Relax restriction on configurations with Rust + GCC plugins to just
the RANDSTRUCT plugin.
'kernel' crate:
- New 'list' module: doubly-linked linked list for use with reference
counted values, which is heavily used by the upcoming Rust Binder.
This includes 'ListArc' (a wrapper around 'Arc' that is guaranteed
unique for the given ID), 'AtomicTracker' (tracks whether a 'ListArc'
exists using an atomic), 'ListLinks' (the prev/next pointers for an
item in a linked list), 'List' (the linked list itself), 'Iter' (an
iterator over a 'List'), 'Cursor' (a cursor into a 'List' that allows
to remove elements), 'ListArcField' (a field exclusively owned by a
'ListArc'), as well as support for heterogeneous lists.
- New 'rbtree' module: red-black tree abstractions used by the upcoming
Rust Binder. This includes 'RBTree' (the red-black tree itself),
'RBTreeNode' (a node), 'RBTreeNodeReservation' (a memory reservation
for a node), 'Iter' and 'IterMut' (immutable and mutable iterators),
'Cursor' (bidirectional cursor that allows to remove elements), as
well as an entry API similar to the Rust standard library one.
- 'init' module: add 'write_[pin_]init' methods and the 'InPlaceWrite'
trait. Add the 'assert_pinned!' macro.
- 'sync' module: implement the 'InPlaceInit' trait for 'Arc' by
introducing an associated type in the trait.
- 'alloc' module: add 'drop_contents' method to 'BoxExt'.
- 'types' module: implement the 'ForeignOwnable' trait for
'Pin<Box<T>>' and improve the trait's documentation. In addition,
add the 'into_raw' method to the 'ARef' type.
- 'error' module: in preparation for the upcoming Rust support for
32-bit architectures, like arm, locally allow Clippy lint for those.
Documentation:
- https://rust.docs.kernel.org has been announced, so link to it.
- Enable rustdoc's "jump to definition" feature, making its output a
bit closer to the experience in a cross-referencer.
- Debian Testing now also provides recent Rust releases (outside of
the freeze period), so add it to the list.
MAINTAINERS:
- Trevor is joining as reviewer of the "RUST" entry.
And a few other small bits.
