Quentin Monnet 05a06be722 bpftool: Return an error on prog dumps if both CFG and JSON are required ... We do not support JSON output for control flow graphs of programs with bpftool. So far, requiring both the CFG and JSON output would result in producing a null JSON object. It makes more sense to raise an error directly when parsing command line arguments and options, so that users know they won't get any output they might expect. If JSON is required for the graph, we leave it to Graphviz instead: # bpftool prog dump xlated <REF> visual | dot -Tjson Suggested-by: Eduard Zingerman <eddyz87@gmail.com> Signed-off-by: Quentin Monnet <quentin@isovalent.com> Link: https://lore.kernel.org/r/20230405132120.59886-5-quentin@isovalent.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>		2023-04-05 21:27:27 -07:00
