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!
