6 years ago Some detailed steps to figure out.
- [x] Simple packet filter demo with classic BPF
- Write assembly in C and directly attach to socket with setsockopt(fd, SOL_SOCKET, SO_ATTACH_FILTER, ...)
- [x] HTTP monitor demo with python BCC
- Write restricted C for extended BPF, and attach with BCC.
- Use eBPF maps to store states and pass data to userspace.
- [ ] Compile eBPF object files with LLVM and attach with C
Explore the language feature and characteristics of BPF/eBPF as well as its capabilities before we move on to consider what and how to automatically generate BPF/eBPF code for protocol specification verification and QoS metrics measurement.
