[$] Standards for use of unsafe Rust in the kernel
Date:
Wed, 14 Aug 2024 14:17:38 +0000
Description:
Rust is intended to let programmers write safer code.
But compilers are
not omniscient, and writing Rust code that interfaces with hardware (or that works with memory outside of Rust's lifetime paradigm) requires, at
some point, the programmer's assurance that some operations are permissible. Benno Lossin suggested adding
some more documentation to the Rust-for-Linux project clarifying the
standards for commenting uses of unsafe in kernel code. There's general agreement that such standards are necessary, but less agreement on exactly when
it is appropriate to use unsafe .
