bpftool-token(8)            System Manager's Manual           bpftool-token(8)

Name
       bpftool-token - tool for inspection and simple manipulation of eBPF
       tokens

SYNOPSIS
       bpftool [OPTIONS] token COMMAND

       OPTIONS := { { -j | --json } [{ -p | --pretty }] | { -d | --debug } }

       COMMANDS := { show | list | help }

TOKEN COMMANDS
       bpftool token { show | list }
       bpftool token help



DESCRIPTION

       bpftool token { show | list }
              List BPF token information for each bpffs mount point containing
              token information on the system. Information include mount point
              path, allowed bpf() system call commands, maps, programs, and
              attach types for the token.

       bpftool prog help
              Print short help message.

OPTIONS

       -h, --help
              Print short help message (similar to bpftool help).

       -V, --version
              Print bpftool's version number (similar to bpftool version), the
              number of the libbpf version in use, and optional features that
              were included when bpftool was compiled. Optional features
              include linking against LLVM or libbfd to provide the
              disassembler for JIT-ted programs (bpftool prog dump jited) and
              usage of BPF skeletons (some features like bpftool prog profile
              or showing pids associated to BPF objects may rely on it).

       -j, --json
              Generate JSON output. For commands that cannot produce JSON,
              this option has no effect.

       -p, --pretty
              Generate human-readable JSON output. Implies -j.

       -d, --debug
              Print all logs available, even debug-level information. This
              includes logs from libbpf as well as from the verifier, when
              attempting to load programs.

EXAMPLES

       # mkdir -p /sys/fs/bpf/token
       # mount -t bpf bpffs /sys/fs/bpf/token
         -o delegate_cmds=prog_load:map_create
         -o delegate_progs=kprobe
         -o delegate_attachs=xdp
       # bpftool token list


          token_info  /sys/fs/bpf/token
                  allowed_cmds:
                    map_create          prog_load
                  allowed_maps:
                  allowed_progs:
                    kprobe
