| # libbpf-rs tests |
| |
| libbpf-rs tests are designed to be independent of libbpf-cargo and underlying |
| compiler versions. To that end, we check in pre-compiled bpf object files in |
| `libbpf-rs/tests/bin`. To help with writing new tests, the original source |
| code for the pre-compiled objects are placed in `libbpf-rs/tests/bin/src`. |
| |
| To regenerate the test bpf object files |
| run bpf_object_regen.sh script via the command: |
| $ ./bpf_object_regen.sh |
| |
| The script bpf_object_regen.sh depends on the following packages installed: |
| |
| bash |
| bpftool (optional) |
| clang |
| libbpf |
| |
