| D | bpftool-iter.rst | 29 A bpf iterator combines a kernel iterating of
31 and a bpf program called for each kernel data object
35 The *pin* command creates a bpf iterator from *OBJ*,
41 Map element bpf iterator requires an additional parameter
42 *MAP* so bpf program can iterate over map elements for
43 that map. User can have a bpf program in kernel to run
47 User can then *cat PATH* to see the bpf iterator output.
58 **# bpftool iter pin bpf_iter_netlink.o /sys/fs/bpf/my_netlink**
62 Create a file-based bpf iterator from bpf_iter_netlink.o and pin it
63 to /sys/fs/bpf/my_netlink

| D | bpftool-net.rst | 5 tool for inspection of netdev/tc related bpf prog attachments
34 List bpf program attachments in the kernel networking subsystem.
45 bpf programs, users should consult other tools, e.g., iproute2.
48 all tc class/qdisc bpf program attachments. Both xdp programs and
49 tc programs are ordered based on ifindex number. If multiple bpf
51 the order will be first all bpf programs attached to tc classes, then
52 all bpf programs attached to non clsact qdiscs, and finally all
53 bpf programs attached to root and clsact qdisc.
56 Attach bpf program *PROG* to network interface *NAME* with
57 type specified by *ATTACH_TYPE*. Previously attached bpf program
