Subject: [BUG] iproute2 - ip -d -j tuntap outputs malformed JSON
Date: Fri, 21 Nov 2025 12:25:41 +0800	[thread overview]
Message-ID: <87jyzkvwoq.fsf@fuzy.me> (raw)

Hi iproute2 maintainers,

    $ sudo ip -d -j tuntap
    [{"ifname":"tun0","flags":["tun","persist"],"processes":["name":"ssh","pid":86812]}]

The “processes” value looks like it should be an array of objects, so
the inner braces seem to be missing:

    [{"ifname":"tun0","flags":["tun","persist"],"processes":[{"name":"ssh","pid":86812}]}]

Could you confirm whether this is a formatting bug or if the output is
intentionally flattened?

Thanks!
