bpftool: Add misc section and probe for large INSN limit
Introduce a new probe section (misc) for probes not related to concrete map types, program types, functions or kernel configuration. Introduce a probe for large INSN limit as the first one in that section. Example outputs: # bpftool feature probe [...] Scanning miscellaneous eBPF features... Large program size limit is available # bpftool feature probe macros [...] /*** eBPF misc features ***/ #define HAVE_HAVE_LARGE_INSN_LIMIT # bpftool feature probe -j | jq '.["misc"]' { "have_large_insn_limit": true } Signed-off-by: Michal Rostecki <mrostecki@opensuse.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Reviewed-by: Quentin Monnet <quentin.monnet@netronome.com> Link: https://lore.kernel.org/bpf/20200108162428.25014-3-mrostecki@opensuse.org
