2019-11-07tools, bpf_asm: Warn when jumps are out of rangeIlya Leoshkevich1-2/+12
When compiling larger programs with bpf_asm, it's possible to accidentally exceed jt/jf range, in which case it won't complain, but rather silently emit a truncated offset, leading to a "happy debugging" situation. Add a warning to help detecting such issues. It could be made an error instead, but this might break compilation of existing code (which might be working by accident).

2017-10-04tools: rename tools/net directory to tools/bpfJakub Kicinski1-0/+656
We currently only have BPF tools in the tools/net directory. We are about to add more BPF tools there, not necessarily networking related, rename the directory and related Makefile targets to bpf.
