| H A D | README | f0fdfefb Tue Aug 18 23:27:57 CDT 2020 Alexei Starovoitov <ast@kernel.org> bpf: Add BPF program and map iterators as built-in BPF programs.
The program and map iterators work similar to seq_file-s.
Once the program is pinned in bpffs it can be read with "cat" tool
to print human readable output. In this case about BPF programs and maps.
For example:
$ cat /sys/fs/bpf/progs.debug
id name attached
5 dump_bpf_map bpf_iter_bpf_map
6 dump_bpf_prog bpf_iter_bpf_prog
$ cat /sys/fs/bpf/maps.debug
id name max_entries
3 iterator.rodata 1
To avoid kernel build dependency on clang 10 separate bpf skeleton generation
into manual "make" step and instead check-in generated .skel.h into git.
Unlike 'bpftool prog show' in-kernel BTF name is used (when available)
to print full name of BPF program instead of 16-byte truncated name.
