selftests: net: declare section names for bpf_offload

2024-04-10T21:03:12+00:00

Non-ancient ip (iproute2-5.15.0, libbpf 0.7.0) refuses to load the sample with maps because we don't generate BTF: libbpf: BTF is required, but is missing or corrupted. ERROR: opening BPF object file failed Enable BTF by adding -g to clang flags. With that done neither of the programs load: libbpf: prog 'func': error relocating .BTF.ext function info: -22 libbpf: prog 'func': failed to relocate calls: -22 libbpf: failed to load object 'ksft-net-drv/net/sample_ret0.bpf.o' Andrii explains that this is because we don't specify section names for the code. Add the section names, too.

We're building more python tests on the netdev side, and some of the classes from the venerable BPF offload tests can be reused. Acked-by: Stanislav Fomichev Acked-by: Martin KaFai Lau Link: https://lore.kernel.org/r/20240409031549.3531084-2-kuba@kernel.org Signed-off-by: Jakub Kicinski
