That sounds interesting ... will you be able to follow up the port with our development, or what is your plan on that? I'd assume that you need to rewrite a rather large chunk of "Linuxism" as you say, and I would assume that porting newer versions as we release would be quite some manual work. > > So I'd like to ask: > 1- Is it better approach to "rewrite" batman-adv.ko [at least > Netlink-ish (let's call "Linuxism") parts] than what I'm doing now? I don't have enough knowledge of FreeBSD to answer that. I would assume that the skb handling and netlink/debugfs parts are Linux specific. You'd at least need to rewrite those. You better don't touch the routing code, I would not advise rewriting that. > 2- Any other efforts are being done out there? I'm not aware. At least nothing serious (I remember someone demanding batman- adv to work in web browsers). :D > 3- is batmand deprecated [So I should mainly focus on batman-adv.ko]? We agreed to not call it deprecated, but there hasn't been any developments in the past 7 years except for some build-specific issues. I'd suggest to focus on batman-adv.ko. batmand may be easier to port though, but I see more people using batman-adv today. > 4- any other comments do you have? :D Good luck! :D And please keep us posted! > > P.S. sorry if I'm not really good at starting conversation from scratch > and out-of-nowhere :D > but I hope by continuing the collaboration we can have better (more > enriched) FreeBSD and better (as in more portable) B.A.T.M.A.N :-) Looking forward to it!
