Add `bpftool token show` command to get token info
from bpffs in /proc/mounts.
Example plain output for `token show`:
token_info /sys/fs/bpf/token
allowed_cmds:
map_create prog_load
allowed_maps:
allowed_progs:
kprobe
allowed_attachs:
xdp
token_info /sys/fs/bpf/token2
allowed_cmds:
map_create prog_load
allowed_maps:
allowed_progs:
kprobe
allowed_attachs:
xdp
Example json output for `token show`:
[{
"token_info": "/sys/fs/bpf/token",
"allowed_cmds": ["map_create", "prog_load"],
"allowed_maps": [],
"allowed_progs": ["kprobe"],
"allowed_attachs": ["xdp"]
}, {
"token_info": "/sys/fs/bpf/token2",
"allowed_cmds": ["map_create", "prog_load"],
"allowed_maps": [],
"allowed_progs": ["kprobe"],
"allowed_attachs": ["xdp"]
}]
