I can set up a persistent Linux tap interface and make it owned by a specific user and group with one of these:tunctl -u someuser -g somegroup -t example.tapip tuntap add dev example.tap mode tap user someuser group somegroupI can confirm the interface is there and see a bit of information about it withip link list dev example.tapBut how, after the fact, can I find out which user or group the interface is owned by?  ip tuntap seems very sparsely documented and ip link list doesn't seem to show ownership.
How can I find out the ownership of a tap interface?
