[PATCH 00/13] [RFC] Rust support

From: Miguel Ojeda Some of you have noticed the past few weeks and months that a serious attempt to bring a second language to the kernel was being forged. We are finally here, with an RFC that adds support for Rust to the Linux kernel. This cover letter is fairly long, since there are quite a f

[PATCH 01/13] kallsyms: Support "big" kernel symbols (2-byte lengths)

From: Miguel Ojeda Rust symbols can become quite long due to namespacing introduced by modules, types, traits, generics, etc. Increasing to 255 is not enough in some cases, and therefore we need to introduce 2-byte lengths to the symbol table. We call these "big" symbols. In order to avoid incr

[PATCH 02/13] kallsyms: Increase maximum kernel symbol length to 512

From: Miguel Ojeda Rust symbols can become quite long due to namespacing introduced by modules, types, traits, generics, etc. For instance, for: pub mod my_module { pub struct MyType; pub struct MyGenericType(T); pub trait MyTrait { fn my_method() -> u32;

[PATCH 03/13] Makefile: Generate CLANG_FLAGS even in GCC builds

From: Miguel Ojeda To support Rust under GCC-built kernels, we need to save the flags that would have been passed if the kernel was being compiled with Clang. The reason is that bindgen -- the tool we use to generate Rust bindings to the C side of the kernel -- relies on libclang to parse C. Ide

[PATCH 05/13] Rust: Compiler builtins crate

From: Miguel Ojeda Rust provides `compiler_builtins` as a port of LLVM's `compiler-rt`. Since we do not need the vast majority of them, we avoid the dependency by providing our own crate. We also need a helpers C source file to contain some forwarders to C macros and inlined functions. For the m

[PATCH 08/13] Rust: Export generated symbols

From: Miguel Ojeda Now that all the shared Rust infrastructure is in, we export all the symbols reusing the `EXPORT_SYMBOL_GPL` macro from C. The lists of symbols are generated on the fly when compiling the crates. There are three main sets of symbols to distinguish: - The ones from the `core

[PATCH 06/13] Rust: Module crate

[PATCH 10/13] Documentation: Rust general information

From: Miguel Ojeda Most of the documentation for Rust is written within the source code itself, as it is idiomatic for Rust projects. This applies to both the shared infrastructure at `rust/` as well as any other Rust module (e.g. drivers) written across the kernel. These documents are general i

[PATCH 07/13] Rust: Kernel crate

[PATCH bpf-next v4 0/6] Add a snprintf eBPF helper

We have a usecase where we want to audit symbol names (if available) in callback registration hooks. (ex: fentry/nf_register_net_hook) A few months back, I proposed a bpf_kallsyms_lookup series but it was decided in the reviews that a more generic helper, bpf_snprintf, would be more useful. This

[PATCH bpf-next v4 3/6] bpf: Add a bpf_snprintf helper

The implementation takes inspiration from the existing bpf_trace_printk helper but there are a few differences: To allow for a large number of format-specifiers, parameters are provided in an array, like in bpf_seq_printf. Because the output string takes two arguments and the array of parameters

[PATCH bpf-next v4 2/6] bpf: Add a ARG_PTR_TO_CONST_STR argument type

[PATCH bpf-next v4 4/6] libbpf: Initialize the bpf_seq_printf parameters array field by field

[PATCH bpf-next v4 1/6] bpf: Factorize bpf_trace_printk and bpf_seq_printf

[PATCH bpf-next v4 5/6] libbpf: Introduce a BPF_SNPRINTF helper macro
