35 A bpf iterator combines a kernel iterating of particular kernel data (e.g.,
36 tasks, bpf_maps, etc.) and a bpf program called for each kernel data object
40 The *pin* command creates a bpf iterator from *OBJ*, and pin it to *PATH*.
44 Map element bpf iterator requires an additional parameter *MAP* so bpf
45 program can iterate over map elements for that map. User can have a bpf
49 User can then *cat PATH* to see the bpf iterator output.
60 **# bpftool iter pin bpf_iter_netlink.o /sys/fs/bpf/my_netlink**
64 Create a file-based bpf iterator from bpf_iter_netlink.o and pin it
65 to /sys/fs/bpf/my_netlink
67 **# bpftool iter pin bpf_iter_hashmap.o /sys/fs/bpf/my_hashmap map id 20**
71 Create a file-based bpf iterator from bpf_iter_hashmap.o and map with
72 id 20, and pin it to /sys/fs/bpf/my_hashmap
