It seems by themselves the patches don't provide any new functionality, but instead look like plumbing to call external code. This is no-go. There were several attempts to do so in the past, so we documented it here: Documentation/bpf/bpf_design_QA.rst Q: New functionality via kernel modules? ---------------------------------------- Q: Can BPF functionality such as new program or map types, new helpers, etc be added out of kernel module code? A: NO. The answer is still the same.
