As I understand it eBPF has also given up on that due to Spectre. As a result you need root to use it on most distros anyway, and the kernel devs aren't going to expand its use (some systems are stuck on cBPF).

So it's not like eBPF is secure and this isn't. They're both insecure in different ways.

So eBPF for a WAF isn't worth it?

> Should a microkernel implement eBPF and WASM, or, for the same reasons that justify a microkernel should eBPF and most other things be confined or relegated or segregated in userspace; in terms of microkernel goals like separation of concerns and least privilege and then performance?
