kernel/tools/testing/selftests/net/sample_ret0.bpf.c, branch linux-rolling-stableHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-rolling-stable2024-04-10T21:03:12Zselftests: net: declare section names for bpf_offload2024-04-10T21:03:12ZJakub Kicinskikuba@kernel.org2024-04-09T03:15:48Zurn:sha1:b1c2ce11d42886d08cfa28e38ee07f2b606ced0b
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.

selftests: move bpf-offload test from bpf to net2024-04-10T21:03:12ZJakub Kicinskikuba@kernel.org2024-04-09T03:15:46Zurn:sha1:e59f0e93e92e0ddfd17e3373d586218cf638571e
We're building more python tests on the netdev side, and some
of the classes from the venerable BPF offload tests can be reused.
