2025-01-09bcachefs: Handle -BCH_ERR_need_mark_replicas in gcKent Overstreet
Locking considerations (possibly no longer relevant?) mean that when an accounting update needs a new superblock replicas entry to be created, it's deferred to the transaction commit error path. But accounting updates for gc/fcsk aren't done from the transaction commit path - so we need to handle -BCH_ERR_btree_insert_need_mark_replicas locally.

2025-01-09bcachefs: add counter_flags for countersHongbo Li
In bcachefs, io_read and io_write counter record the amount of data which has been read and written. They increase in unit of sector, so to display correctly, they need to be shifted to the left by the size of a sector. Other counters like io_move, move_extent_{read, write, finish} also have this problem. In order to support different unit, we add extra column to mark the counter type by using TYPE_COUNTER and TYPE_SECTORS in BCH_PERSISTENT_COUNTERS().

2025-01-09net: ethernet: ti: cpsw_ale: Fix cpsw_ale_get_field()Sudheer Kumar Doredla
CPSW ALE has 75-bit ALE entries stored across three 32-bit words. The cpsw_ale_get_field() and cpsw_ale_set_field() functions support ALE field entries spanning up to two words at the most. The cpsw_ale_get_field() and cpsw_ale_set_field() functions work as expected when ALE field spanned across word1 and word2, but fails when ALE field spanned across word2 and word3. For example, while reading the ALE field spanned across word2 and word3 (i.e. bits 62 to 64), the word3 data shifted to an incorrect position due to the index becoming zero while flipping. The same issue occurred when setting an ALE entry. This issue has not been seen in practice but will be an issue in the future if the driver supports accessing ALE fields spanning word2 and word3 Fix the methods to handle getting/setting fields spanning up to two words.

2025-01-09scsi: core: Fix command pass through retry regressionMike Christie
scsi_check_passthrough() is always called, but it doesn't check for if a command completed successfully. As a result, if a command was successful and the caller used SCMD_FAILURE_RESULT_ANY to indicate what failures it wanted to retry, we will end up retrying the command. This will cause delays during device discovery because of the command being sent multiple times. For some USB devices it can also cause the wrong device size to be used. This patch adds a check for if the command was successful. If it is we return immediately instead of trying to match a failure.

2025-01-10rust: use host dylib naming convention to support macOSTamir Duberstein
Because the `macros` crate exposes procedural macros, it must be compiled as a dynamic library (so it can be loaded by the compiler at compile-time). Before this change the resulting artifact was always named `libmacros.so`, which works on hosts where this matches the naming convention for dynamic libraries. However the proper name on macOS would be `libmacros.dylib`. This turns out to matter even when the dependency is passed with a path (`--extern macros=path/to/libmacros.so` rather than `--extern macros`) because rustc uses the file name to infer the type of the library (see link). This is because there's no way to specify both the path to and the type of the external library via CLI flags. The compiler could speculatively parse the file to determine its type, but it does not do so today. This means that libraries that match neither rustc's naming convention for static libraries nor the platform's naming convention for dynamic libraries are *rejected*. The only solution I've found is to follow the host platform's naming convention. This patch does that by querying the compiler to determine the appropriate name for the artifact. This allows the kernel to build with CONFIG_RUST=y on macOS.

2025-01-10rust: kernel: move `build_error` hidden function to prevent mistakesMiguel Ojeda
Users were using the hidden exported `kernel::build_error` function instead of the intended `kernel::build_error!` macro, e.g. see the previous commit. To force to use the macro, move it into the `build_assert` module, thus making it a compilation error and avoiding a collision in the same "namespace". Using the function now would require typing the module name (which is hidden), not just a single character. Now attempting to use the function will trigger this error with the right suggestion by the compiler: error[E0423]: expected function, found macro `kernel::build_error` --> samples/rust/rust_minimal.rs:29:9 | 29 | kernel::build_error(); | ^^^^^^^^^^^^^^^^^^^ not a function | help: use `!` to invoke the macro | 29 | kernel::build_error!(); | + An alternative would be using an alias, but it would be more complex and moving it into the module seems right since it belongs there and reduces the amount of code at the crate root.

2025-01-10rust: give Clippy the minimum supported Rust versionMiguel Ojeda
Clippy's lints may avoid emitting a suggestion to use a language or library feature that is not supported by the minimum supported version, if given by the `msrv` field in the configuration file. For instance, Clippy should not suggest using `let ... else` in a lint if the MSRV did not implement that syntax. If the MSRV is not provided, Clippy will assume all features are available. Thus enable it with the minimum Rust version the kernel supports. Note that there is currently a small disadvantage in doing so: since we still use unstable features that nevertheless work in the range of versions we support (e.g. `#[expect(...)]`), we lose suggestions for those. However, over time we will stop using unstable features (especially language and library ones) as it is our goal, thus, in the end, we will want to have the `msrv` set. Rust is also considering adding a similar feature in `rustc` too, which we should probably enable if it becomes available [2].

2025-01-09drm/amdgpu/gfx10: Enable cleaner shader for GFX10.3.2/10.3.4/10.3.5 GPUsSrinivasan Shanmugam
Enable the cleaner shader for GFX10.3.2/10.3.4/10.3.5 GPUs to provide data isolation between GPU workloads. The cleaner shader is responsible for clearing the Local Data Store (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which helps prevent data leakage and ensures accurate computation results. This update extends cleaner shader support to GFX10.3.2/10.3.4/10.3.5 GPUs, previously available for GFX10.3.0. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.

2025-01-09drm/amdgpu: Fix shift type in amdgpu_debugfs_sdma_sched_mask_set()Dan Carpenter
The "mask" and "val" variables are type u64. The problem is that the BIT() macros are type unsigned long which is just 32 bits on 32bit systems. It's unlikely that people will be using this driver on 32bit kernels and even if they did we only use the lower AMDGPU_MAX_SDMA_INSTANCES (16) bits. So this bug does not affect anything in real life. Still, for correctness sake, u64 bit masks should use BIT_ULL().

2025-01-09drm/amd/display: Increase sanitizer frame larger than limit when compile ↵Nathan Chancellor
testing with clang Commit 24909d9ec7c3 ("drm/amd/display: Overwriting dualDPP UBF values before usage") added a new warning in dml2/display_mode_core.c when building allmodconfig with clang: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6268:13: error: stack frame size (3128) exceeds limit (3072) in 'dml_prefetch_check' [-Werror,-Wframe-larger-than] 6268 | static void dml_prefetch_check(struct display_mode_lib_st *mode_lib) | ^ Commit be4e3509314a ("drm/amd/display: DML21 Reintegration For Various Fixes") introduced one in dml2_core/dml2_core_dcn4_calcs.c with the same configuration: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7236:13: error: stack frame size (3256) exceeds limit (3072) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than] 7236 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params) | ^ In the case of the first warning, the stack usage was already at the limit at the parent change, so the offending change was rather innocuous. In the case of the second warning, there was a rather dramatic increase in stack usage compared to the parent: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_dcn4_calcs.c:7032:13: error: stack frame size (2696) exceeds limit (2048) in 'dml_core_mode_support' [-Werror,-Wframe-larger-than] 7032 | static bool dml_core_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params) | ^ This is an unfortunate interaction between an issue with stack slot reuse in LLVM that gets exacerbated by sanitization (which gets enabled with all{mod,yes}config) and function calls using a much higher number of parameters than is typical in the kernel, necessitating passing most of these values on the stack. While it is possible that there should be source code changes to address these warnings, this code is difficult to modify for various reasons, as has been noted in other changes that have occurred for similar reasons, such as commit 6740ec97bcdb ("drm/amd/display: Increase frame warning limit with KASAN or KCSAN in dml2"). Increase the frame larger than limit when compile testing with clang and the sanitizers enabled to avoid this breakage in all{mod,yes}config, as they are commonly used and valuable testing targets. While it is not the best to hide this issue, it is not really relevant when compile testing, as the sanitizers are commonly stressful on optimizations and they are only truly useful at runtime, which COMPILE_TEST states will not occur with the current build.
