LINUX KERNEL --
In the past year or so there's been a lot to talk about when it comes to eBPF in the Linux kernel as an in-kernel virtual machine. The latest functionality being worked on is supporting eBPF for unprivileged users.

Alexei Starovoitov has published patches to "liberate eBPF from CAP_SYS_ADMIN" and takes care of work from its start to allow it to be used by non-root users.

However, not all users will be able to benefit from eBPF as non-root users. Alexei explained, "Unprivileged eBPF is only meaningful for 'socket filter'-like programs. eBPF programs for tracing and TC classifiers/actions will stay root only."

Those wishing to learn more can see this kernel mailing list post with the relevant patches.
