LINUX KERNEL --
The BPF In-Kernel Virtual Machine will likely see new functionality with the next Linux kernel release cycle, Linux 4.1.

A new patch series led by Alexei Starovoitov appears about ready as new tracing code that allows for eBPF programs to be attached to KProbes. Alexei mentioned in his latest tracing patch series that this eBPF code for kprobes appears ready, "I think it's good to go."

While the Berkeley Packet Filter started with network packet filtering, it's since been extended to largely become a universal in-kernel virtual machine. Via the new patch series are also some example applications for letting BPF do I/O latency analysis and kmem_alloc/free tracker.
