🦋 CANLOOP(4) 🦋

okay bestie, welcome to the Kernel Interfaces Manual — this page is all about canloop, the software loopback CAN network interface ✨

🌸 NAME 🌸

canloop — a software loopback CAN network interface, periodt 💅

🎀 SYNOPSIS 🎀

pseudo-device canloop

✨ DESCRIPTION ✨

So the canloop pseudo interface is literally a loopback interface for the CAN layer. No cap. 🫶

It can be used as a destination by a CAN application when there is no CAN hardware available. It's giving "we make it work anyway" main character energy 😌💖

Other sockets bound to the same canloop interface — or not bound to any interface at all — will receive the frames. Yes, those sockets. They get the frames. iykyk 🦋

canloop interfaces can be created by using the ifconfig(8) create command. Slay. 🔥

🌈 SEE ALSO 🌈

go read those too, bestie — they're iconic 👑

💜 HISTORY 💜

The canloop device appeared in NetBSD 8.0. Not me being nostalgic for a whole release era 😭💀

source/version situation: Debian; date stamp: May 18, 2017 — that's the tea, bestie, bye fr fr 🎀💖
