Userspace wifi frame crafting

[redfast00]

Hi, ESP8266 can send (almost) arbitrary packets. I am trying to implement EAP on an ESP8266, and I am looking for a library that makes it easy to craft 802.11 packets. I noticed there is no support for making packets (I think). Is making 802.11 packets in scope of this project?

Yes, see https://github.com/br101/libuwifi/blob/master/core/inject.c

So far it only contains the two packet types I needed. Contributions welcome ;)

Oh, hadn't noticed it. Will look into it when I have some spare time (around July/August). Thanks!

Hallo @br101,

Now it has probe response and data frame. Are you planning to write function to create IEEE802.11 frame for all types and subtypes. I.e separate function for each type?? (Current code structure looks like that)

[br101]

Well, i have just implemented what I needed at the time. A separate function for each frame type will result in a lot of functions, so if you have a better idea, please go for it... :)

[warlock20]

Exactly, current structure will result in lot of functions for each frame type.
I have other ideas. Let me try it and will update after its done.

@warlock20: I am curious to what you will implement. Any chance to get an EAP access point working?

[warlock20]

@redfast00 Haven't tried.. What you want to achieve?

[redfast00]

It would be really cool to be able to set up a rogue EAP access point to obtain hashes (like mana-hostapd but on an ESP8266).

@redfast00 First I need to work on this and other features and I never used ESP8266 before. You can start the working and we will see.. :-)

please note that frame injection does not work on esp8266 yet (but possible to do afaik)
