Advantages of kdbus with enhanced capabilities feature

[Pedro Giffuni]

FWIW;

While kdbus seems to be in a somewhat flaky situation in other 
communities, we still have interest in *some* form of IPC
for the kernel, or perhaps something mixed kernel/userland.

One such mechanism could be Solaris doors, which were implemented
for linux but never caught up much steam:

I think there was also something interesting done for a microkernel
(L4?) and it was made compatible with an Apple's Darwin Mach ports.

It's an interesting topic for research, but if you want to do it
as a GSoC you will have to discuss this with the mentor from the
GSoC ideas page.
