Hey everybody, I see that sockets, protocols and network device drivers are pieces of a same puzzle. So after some digging and thinking I'm considering write the driver in such way that it only deals with data link layer, no socket bits. It should sit at 2nd OSI layer and let routing and segmenting for the other layers. This way everything that works with TCP/UDP/IP should work with our little radio transciver. The one million dollars question remains, how do this with only 32bytes MTU and as a bonus, how to spread the communications of several nodes throughout all available channels so that I have less collisions as possible. The first idea that I have was using some connection based protocol where, when someone wants to transfers some N bytes of data, the source makes a request to destination which choses one avaible channel to be used for the transfers. The data is transferred through the selected channel and the connection is closed. The comunication used to open some "connection" would be done on a "control channel" which should be used as few as possible, while the realdata is transmitted on *some of* "data channels". What you guys think? I'll keep working (as much as my sparse time allows me) to get this up and running then I think at details, if someone has interest here is the (not yet finished) code: https://github.com/gkos/nrf24l01p Cheers 2016-03-28 17:08 GMT-03:00 Rami Rosen <roszenrami@xxxxxxxxx>: > Hi, > Header files under include/net are for kernel internal use. > Header files under include/uapi are for exposure to userspace: > http://lxr.free-electrons.com/source/include/uapi/ > > Regards, > Rami Rosen > http://ramirose.wix.com/ramirosen > > בתאריך 28 במרץ 2016 18:04, "Manoj Nayak" <manojnayak2005@xxxxxxxxx> כתב: >> >> > 1) Is it possible to write a new protocol for linux with an out of >> > tree module without modifing socket.h file? >> >> I think this has been already tried in the following code. >> >> http://lxr.free-electrons.com/source/include/net/bluetooth/bluetooth.h#L36 >> >> http://lxr.free-electrons.com/source/include/linux/socket.h#L239 >> >> The challenge is to expose this development specific header file to >> userspace. >> The following document talks about that. >> >> http://kernelnewbies.org/KernelHeaders >> >> Regards >> Manoj Nayak >> >> >> _______________________________________________ >> Kernelnewbies mailing list >> Kernelnewbies@xxxxxxxxxxxxxxxxx >> http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies >> > > _______________________________________________ > Kernelnewbies mailing list > Kernelnewbies@xxxxxxxxxxxxxxxxx > http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies > -- "Do or do not.
