bpftool: show flow_dissector attachment status
Right now there is no way to query whether BPF flow_dissector program is attached to a network namespace or not. In previous commit, I added support for querying that info, show it when doing `bpftool net`: $ bpftool prog loadall ./bpf_flow.o \ /sys/fs/bpf/flow type flow_dissector \ pinmaps /sys/fs/bpf/flow $ bpftool prog 3: flow_dissector name _dissect tag 8c9e917b513dd5cc gpl loaded_at 2019-04-23T16:14:48-0700 uid 0 xlated 656B jited 461B memlock 4096B map_ids 1,2 btf_id 1 ... $ bpftool net -j [{"xdp":[],"tc":[],"flow_dissector":[]}] $ bpftool prog attach pinned \ /sys/fs/bpf/flow/flow_dissector flow_dissector $ bpftool net -j [{"xdp":[],"tc":[],"flow_dissector":["id":3]}] Doesn't show up in a different net namespace: $ ip netns add test $ ip netns exec test bpftool net -j [{"xdp":[],"tc":[],"flow_dissector":[]}] Non-json output: $ bpftool net xdp: tc: flow_dissector: id 3 v2: * initialization order (Jakub Kicinski) * clear errno for batch mode (Quentin Monnet) Signed-off-by: Stanislav Fomichev <sdf@google.com> Reviewed-by: Quentin Monnet <quentin.monnet@netronome.com> Reviewed-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
