Capability-based IPC for Linux


Bus1 is a subsystem to provide object-oriented Inter-Process Communication on Linux. It is a lightweight and scalable way for services and operating system tasks to share signals, data and resources; while at the same time allowing modularization, privilege separation, information hiding and isolation.

Bus1 uses lightweight handles to represent objects. It supports single-copy data transfer, message multicast and gives global-order guarantees.

Bus1 itself does not maintain any globally shared state, all references to objects need to be explicitely handed out to be visible to a peer.
