KDBUS Kernel D-Bus Code Continues Advancing

Linux Kernel

While KDBUS isn't yet ready for merging into the mainline Linux kernel, work on this kernel D-Bus implementation continues moving forward in step with systemd.

Last month I wrote about KDBUS and systemd now working and making a bootable Fedora system. That milestone ended out 2013 while last week Lennart Poettering presented on KDBUS at Linux.Conf.Au.

Kernel developers continue to pursue adding D-Bus to the kernel as a better IPC mechanism with it being "fantastic and solves real problems." The design of D-Bus was described by Lennart during his LCA presentation as being the right approach and D-Bus is the single most used local, high-level IPC system on Linux.

The KDBUS port to the kernel is suitable for large amounts of data and is zero-copy, very efficient, comprehensive credentials, provides implicit timestammping, available during the entire Linux system process, open for security modules to hook into from the kernel side, activation is identical to activation of other services, and the user-space is made much simpler. View the LCA video or check out the PDF slides for a full explanation.

Greg Kroah-Hartman has now blogged the latest KDBUS details. Greg also points out a systemd hack-fest is coming up before FOSDEM, the code is still on GitHub, and it's unlikely that KDBUS will replace Android's Binder code in the near future.
