[PATCH bpf-next 0/4] RV64 BPF JIT Optimizations

2020-05-05 Thread Luke Nelson
This patch series introduces a set of optimizations to the BPF JIT on RV64. The optimizations are related to the verifier zero-extension optimization and BPF_JMP BPF_K. We tested the optimizations on a QEMU riscv64 virt machine, using lib/test_bpf and test_verifier, and formally verified their
