Kernel DBus Now Boots With Systemd On Fedora

Posted by timothy on from the trying-new-things dept.

An anonymous reader writes "Red Hat developers doing some holiday hacking have managed to get a bootable system with systemd + KDBUS on Fedora 20. KDBUS is a new DBus implementation for the Linux kernel that provides greater security and better performance than the DBus daemon in user-space. Systemd in turn interfaces with KDBUS for user-space interaction. Testing was done on Fedora 20 but the systemd + KDBUS configuration should work on any modern distribution when using the newest code."

    Why do we need in-kernel DBUS implementation. And please don't tell me about performance, lot's of software with much higher performance requirements is more than happy in userland...

  2. More Bloat ? by fluffy99 · · Score: 5, Insightful

    Why is this NOT another example of kernel bloat, and the opposite direcion they should be heading (ie getting user stuff out of the kernel)? Seems like the primary use of D-BUS is for the desktop components, which already abuse/overuse inter-process communication. The "huge performance improvement" is only for those processes that shouldn't be abusing this anyway.

    Nope, it's because gotos are very nice for error handling over rats nests of if/else. Which is what its predominate use in the kernel is.
