`bpftool prog list` and other bpftool subcommands that show BPF program names currently get them from bpf_prog_info.name. That field is limited to 16 (BPF_OBJ_NAME_LEN) chars which leads to truncated names since many progs have much longer names. The idea of this change is to improve all bpftool commands that output prog name so that bpftool uses info from BTF to print program names if available. It tries bpf_prog_info.name first and fall back to btf only if the name is suspected to be truncated (has 15 chars length). Right now `bpftool p show id <id>` returns capped prog name <id>: kprobe name example_cap_cap tag 712e... ... With this change it would return <id>: kprobe name example_cap_capable tag 712e... ... Note, other commands that print prog names (e.g. "bpftool cgroup tree") are also addressed in this change. Signed-off-by: Raman Shukhau <ramasha@fb.com>
