The Android system was once famous for extensive, out-of-tree kernel
enhancements. Many of those have been eliminated or upstreamed over
the years, bringing Android much closer to the mainline kernel. One
significant component in the “upstreamed” category is Binder, an
interprocess communication mechanism that is used only by Android. There
are a number of factors that make Binder a good candidate for rewriting in
the Rust language; at the 2023 Linux
Plumbers Conference, Carlos Llamas and Alice Rhyl described the
motivation behind and implementation of a rewrite of Binder in Rust.
