Userspace eBPF VM
This project aims to create an Apache-licensed library for executing eBPF programs. The primary implementation of eBPF lives in the Linux kernel, but due to its GPL license it can't be used in many projects.
[Linux documentation for the eBPF instruction set] (https://www.kernel.org/doc/Documentation/networking/filter.txt).
This project includes an eBPF assembler, disassembler, interpreter, JIT compiler for x86-64, and instruction set reference.
Run make -c vm to build the VM. This produces a static library libubpf.a
and a simple executable used by the testsuite.
You'll need [Clang 3.7] (http://llvm.org/releases/download.html#3.7.0).
clang-3.7 -O2 -target bpf -c prog.c -o prog.o
objcopy -I elf64-little -O binary prog.o prog.bin
You can then pass the contents of prog.bin to ubpf_create, or to the stdin of
the vm/test binary.
Please fork the project on GitHub and open a pull request. You can run all the
tests with nosetests.
