vm: add strcmp_ext for use by testcases Also add a testcase that copies strings to the stack and calls strcmp_ext.
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)
[Instruction set reference] (https://github.com/iovisor/bpf-docs/blob/master/eBPF.md)
This project includes an eBPF assembler, disassembler, interpreter, and JIT compiler for x86-64.
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
You can then pass the contents of prog.o to ubpf_load_elf, 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.
