What to know

  • Linux 7.4 kernel removes the C-based Binder driver that handled interprocess communication for all Android devices, ending its role after growing complex over years of maintenance.
  • The Rust-based Binder replacement has achieved feature parity with the C implementation and reportedly outperforms it in some benchmarks, with billions of future Android devices positioned to use it.
  • The transition represents a major milestone for Rust in the Linux kernel, with the Binder driver becoming the earliest prominent Rust-based kernel driver to reach production scale.

“Google's C-written Binder driver has left the kernel with the Rust-based modern Binder driver ready to take for the role of being used by all future Android devices”
