Displaying cookies for kprobe multi link, in plain mode:
# bpftool link
...
1397: kprobe_multi prog 47532
kretprobe.multi func_cnt 3
addr cookie func [module]
ffffffff82b370c0 3 bpf_fentry_test1
ffffffff82b39780 1 bpf_fentry_test2
ffffffff82b397a0 2 bpf_fentry_test3
And in json mode:
# bpftool link -j | jq
...
{
"id": 1397,
"type": "kprobe_multi",
"prog_id": 47532,
"retprobe": true,
"func_cnt": 3,
"missed": 0,
"funcs": [
{
"addr": 18446744071607382208,
"func": "bpf_fentry_test1",
"module": null,
"cookie": 3
},
{
"addr": 18446744071607392128,
"func": "bpf_fentry_test2",
"module": null,
"cookie": 1
},
{
"addr": 18446744071607392160,
"func": "bpf_fentry_test3",
"module": null,
"cookie": 2
}
]
}
Cookie is attached to specific address, and because we sort addresses
before printing, we need to sort cookies the same way, hence adding
the struct addr_cookie to keep and sort them together.
Also adding missing dd.sym_count check to show_kprobe_multi_json.
