Add ability to access DGRAM packet sockets on Linux. #21

Not sure this is exactly what you would want, so I thought I'd just send it for review.

hugelgupf commented 6 years ago

ping?

mdlayher commented 6 years ago

Interesting change. Do you have a concrete use case for this?

It can probably go in, but we may want to look at an additional options API for platform-specific options like this.

hugelgupf commented 6 years ago

I'm just tired of filling in ethernet headers myself in DHCP clients. (at least the v4 seems to currently have a need for raw sockets.)

hugelgupf commented 6 years ago

(Actually, I likely won't need to do all that after all, so nevermind :))

mdlayher commented 6 years ago

I forgot that DHCP clients may be a bit more awkward than servers since they don't have an IP yet. Let me know if you find a workable solution either way.

hugelgupf commented 6 years ago

Actually, I would like to get this in. I'm trying to eventually not use this, but right now this is the only way I can make my client work. I may have to screw with SO_BINDTODEVICE to get regular sockets to work. At least for DHCPv4 raw sockets seem to be necessary right now. (DHCPv6 at least has the EUI64 address to bind to...)
