Description
The new TUN subsystem has a number of things that should be fixed.
- TAP-related code.
Does this actually work? (It doesn't look like it.) FreeBSD does have a unified TUN/TAP driver in their kernel, but there's a lot of TAP-related branching that we do not have. It may make more sense to remove a lot of this (as it doesn't appear to be correct anyway) until/when we actually implement TAP support.
- Separate driver interface.
There's a lot of places where the network device module reads/writes into the driver interface or otherwise interacts with it across a FD boundary. This should be done away with, and the published device in devfs managed directly from the network device module. This should simplify a lot of code.
- Proper path placement.
Reading FreeBSD's manual page, TUN interfaces behave like any other network interface (can be used with ifconfig, etc.) We thus shouldn't have /dev/tun0
, but rather /dev/net/tun/0
etc. (As TUN interfaces are created on-demand, there won't be a /dev/net/tun
directory at all unless one is created.)

Attaching an openvpn patch to help. This refactor the one in haikuports to be "more sane" (and follow this new naming)
- fixing the odd static tap to a dynamic tun
- making the dynamic_name equal to the full path (later in the code it mentions dynamic_name is used simply for ifconfig calls.. our ifconfig uses full device paths)
Feel free to use, or adjust

Overhaul done in hrev57427.
Reassigning to myself. I guess I will take a look at these things next week.
