2023-04-12rust: error: Add a helper to convert a C ERR_PTR to a `Result`Sven Van Asbroeck
Some kernel C API functions return a pointer which embeds an optional `errno`. Callers are supposed to check the returned pointer with `IS_ERR()` and if this returns `true`, retrieve the `errno` using `PTR_ERR()`. Create a Rust helper function to implement the Rust equivalent: transform a `*mut T` to `Result<*mut T>`. Lina: Imported from rust-for-linux/linux, with subsequent refactoring and contributions squashed in and attributed below. Renamed the function to from_err_ptr().

2023-04-12rust: sync: arc: Add UniqueArc<MaybeUninit<T>::assume_init()Asahi Lina
We can already create `UniqueArc<MaybeUninit<T>>` instances with `UniqueArc::try_new_uninit()` and write to them with `write()`. Add the missing unsafe `assume_init()` function to promote it to `UniqueArc<T>`, so users can do piece-wise initialization of the contents instead of doing it all at once as long as they keep the invariants (the same requirements as `MaybeUninit::assume_init()`). This mirrors the std `Arc::assume_init()` function. In the kernel, since we have `UniqueArc`, arguably this only belongs there since most use cases will initialize it immediately after creating it, before demoting it to `Arc` to share it. [ Miguel: The "Rust pin-init API for pinned initialization of structs" patch series [1] from Benno Lossin contains a very similar patch: rust: sync: add `assume_init` to `UniqueArc` Adds the `assume_init` function to `UniqueArc<MaybeUninit<T>>` that unsafely assumes the value to be initialized and yields a value of type `UniqueArc<T>`. This function is used when manually initializing the pointee of an `UniqueArc`. To make that patch a noop and thus drop it, I adjusted the `SAFETY` comment here to be the same as in the current latest version of that series (v7). I have also brought the `Reviewed-by`s there into here, and reworded the `Co-authored-by` into `Co-developed-by`. ] Link: https://lore.kernel.org/r/20230408122429.1103522-5-y86-dev@protonmail.com [1] Co-developed-by: Benno Lossin <benno.lossin@proton.me> Signed-off-by: Benno Lossin <benno.lossin@proton.me> Signed-off-by: Asahi Lina <lina@asahilina.net> Reviewed-by: Gary Guo <gary@garyguo.net> Reviewed-by: Wedson Almeida Filho <walmeida@microsoft.com> Reviewed-by: Andreas Hindborg <a.hindborg@samsung.com> Reviewed-by: Alice Ryhl <aliceryhl@google.com> Link: https://lore.kernel.org/r/20230224-rust-arc-v2-2-5c97a865b276@asahilina.net Signed-off-by: Miguel Ojeda <ojeda@kernel.org>

2023-04-10rust: macros: Allow specifying multiple module aliasesAsahi Lina
Modules can (and usually do) have multiple alias tags, in order to specify multiple possible device matches for autoloading. Allow this by changing the alias ModuleInfo field to an Option<Vec<String>>. Note: For normal device IDs this is autogenerated by modpost (which is not properly integrated with Rust support yet), so it is useful to be able to manually add device match aliases for now, and should still be useful in the future for corner cases that modpost does not handle. This pulls in the expect_group() helper from the rfl/rust branch (with credit to authors).

2023-04-10rust: Enable the new_uninit feature for kernel and driver cratesAsahi Lina
The unstable new_uninit feature enables various library APIs to create uninitialized containers, such as `Box::assume_init()`. This is necessary to build abstractions that directly initialize memory at the target location, instead of doing copies through the stack. Will be used by the DRM scheduler abstraction in the kernel crate, and by field-wise initialization (e.g. using `place!()` or a future replacement macro which may itself live in `kernel`) in driver crates.

git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl Pull compute express link (cxl) fixes from Dan Williams: "Several fixes for driver startup regressions that landed during the merge window as well as some older bugs. The regressions were due to a lack of testing with what the CXL specification calls Restricted CXL Host (RCH) topologies compared to the testing with Virtual Host (VH) CXL topologies. A VH topology is typical PCIe while RCH topologies map CXL endpoints as Root Complex Integrated endpoints. The impact is some driver crashes on startup. This merge window also added compatibility for range registers (the mechanism that CXL 1.1 defined for mapping memory) to treat them like HDM decoders (the mechanism that CXL 2.0 defined for mapping Host-managed Device Memory). That work collided with the new region enumeration code that was tested with CXL 2.0 setups, and fails with crashes at startup. Lastly, the DOE (Data Object Exchange) implementation for retrieving an ACPI-like data table from CXL devices is being reworked for v6.4. Several fixes fell out of that work that are suitable for v6.3. All of this has been in linux-next for a while, and all reported issues [1] have been addressed. Summary: - Fix several issues with region enumeration in RCH topologies that can trigger crashes on driver startup or shutdown. - Fix CXL DVSEC range register compatibility versus region enumeration that leads to startup crashes - Fix CDAT endiannes handling - Fix multiple buffer handling boundary conditions - Fix Data Object Exchange (DOE) workqueue usage vs CONFIG_DEBUG_OBJECTS warn splats" Link: http://lore.kernel.org/r/20230405075704.33de8121@canb.auug.org.au [1] * tag 'cxl-fixes-6.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/hdm: Extend DVSEC range register emulation for region enumeration cxl/hdm: Limit emulation to the number of range registers cxl/region: Move coherence tracking into cxl_region_attach() cxl/region: Fix region setup/teardown for RCDs cxl/port: Fix find_cxl_root() for RCDs and simplify it cxl/hdm: Skip emulation when driver manages mem_enable cxl/hdm: Fix double allocation of @cxlhdm PCI/DOE: Fix memory leak with CONFIG_DEBUG_OBJECTS=y PCI/DOE: Silence WARN splat with CONFIG_DEBUG_OBJECTS=y cxl/pci: Handle excessive CDAT length cxl/pci: Handle truncated CDAT entries cxl/pci: Handle truncated CDAT header cxl/pci: Fix CDAT retrieval on big endian

Currently if disk_scan_partitions() failed, GD_NEED_PART_SCAN will still set, and partition scan will be proceed again when blkdev_get_by_dev() is called. However, this will cause a problem that re-assemble partitioned raid device will creat partition for underlying disk.

Some DT devices already have phy device configured in the DT/ACPI. Current implementation scans for a phy unconditionally even though there is a phy listed in the DT/ACPI and already attached. We should check the fwnode if there is any phy device listed in fwnode and decide whether to scan for a phy to attach to.

2023-04-06swiotlb: fix a braino in the alignment check fixPetr Tesarik
The alignment mask in swiotlb_do_find_slots() masks off the high bits which are not relevant for the alignment, so multiple requirements are combined with a bitwise OR rather than AND. In plain English, the stricter the alignment, the more bits must be set in iotlb_align_mask. Confusion may arise from the fact that the same variable is also used to mask off the offset within a swiotlb slot, which is achieved with a bitwise AND.
