BPF originally stood for Berkeley Packet Filter, but has been extended in Linux to become a generic kernel execution engine, capable of running a new type of user-defined and kernel-mode applications.

After 25 months of development the Debian project is proud to present its new stable version 10 (code name "buster"), which will be supported for the next 5 years thanks to the combined work of the Debian Security team and of the Debian Long Term Support team.

Unikernels have demonstrated enormous advantages over Linux in many important domains, causing some to propose that the days of Linux’s dominance may be coming to an end. On the contrary, we believe that unikernels’ advantages represent the next natural evolution for Linux, as it can adopt the best ideas from the unikernel approach and, along with its battle-tested codebase and large open source community, continue to dominate. In this paper, we posit that an up- streamable unikernel target is achievable from the Linux kernel, and, through an early Linux unikernel prototype, demonstrate that some simple changes can bring dramatic performance advantages.
