tools/bpf: selftests: Add bpf_iter selftests
The added test includes the following subtests:
- test verifier change for btf_id_or_null
- test load/create_iter/read for
ipv6_route/netlink/bpf
tools/bpf: selftests: Add bpf_iter selftests
The added test includes the following subtests:
- test verifier change for btf_id_or_null
- test load/create_iter/read for
ipv6_route/netlink/bpf_map/task/task_file
- test anon bpf iterator
- test anon bpf iterator reading one char at a time
- test file bpf iterator
- test overflow (single bpf program output not overflow)
- test overflow (single bpf program output overflows)
- test bpf prog returning 1
The ipv6_route tests the following verifier change
- access fields in the variable length array of the structure.
The netlink load tests the following verifier change
- put a btf_id ptr value in a stack and accessible to
tracing/iter programs.
The anon bpf iterator also tests link auto attach through skeleton.
