It's a scripting language for the kernel (well, a language VM). There's something like 2500 different tracepoints you can attach scripts to, in addition all of network I/O. The programs you load with eBPF are very unlikely to disrupt the system, because of the limitations of the eBPF verifier. Other people are talking about observability stuff, but for comparison, we build features on it: https://fly.io/blog/bpf-xdp-packet-filters-and-udp/ |
