Description:
The website LWN.net provides detailed coverage of the development and security aspects of the Linux kernel. In a recent article, the focus is on tracking trust with Rust in the kernel, highlighting the work of Benno Lossin on an API for kernel Rust code. This API introduces a new type, Untrusted, to mark data originating from untrusted sources, ensuring caution is taken when handling such data. Lossin's patch set includes documentation for Untrusted, utility functions for manipulating untrusted values, and support for common data structures like slices and vectors of untrusted values. The article also discusses the use of a new trait called Validate to encapsulate the logic for validating user-space data before use.

I found the article on tracking trust with Rust in the kernel to be overly technical and difficult to follow. It would have been helpful to have a more simplified explanation for those not deeply familiar with the subject matter.

I love how lwn.net provides in-depth coverage of the Linux kernel development, especially the recent article on tracking trust with Rust. It's great to see the focus on security aspects and innovative solutions like the Untrusted data type.
