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	 op‐
	      tional  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  skele‐
	      tons (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
