Add `-Zsanitize=kernel-hwaddress` by Darksonn · Pull Request #153049 · rust-lang/rust

Darksonn · 2026-02-24T14:39:37Z

The Linux kernel has a config option called CONFIG_KASAN_SW_TAGS that enables -fsanitize=kernel-hwaddress. This is not supported by Rust.

Note that #[sanitize(kernel_hwaddress = "off")] could be supported as an annotation on statics, but since it's also missing for #[sanitize(hwaddress = "off")], I did not add it.
