A Low-Power Wide-Area Network (LPWAN) is a type of wireless telecommunication wide area network designed to allow long range communications at a low bit rate among things (connected objects), such as sensors operated on a battery. It can be used widely in IoT area. LoRaWAN, which is one kind of implementation of LPWAN, is a medium access control (MAC) layer protocol for managing communication between LPWAN gateways and end-node devices, maintained by the LoRa Alliance. LoRaWAN™ Specification could be downloaded at: https://lora-alliance.org/lorawan-for-developers However, LoRaWAN is not implemented in Linux kernel right now, so I am trying to develop it. Here is my repository: https://github.com/starnight/LoRa/tree/lorawan-ndo/LoRaWAN Because it is a kind of network, the ideal usage in an user space program should be like "socket(PF_LORAWAN, SOCK_DGRAM, 0)" and with other socket APIs. Therefore, the definitions like AF_LORAWAN, PF_LORAWAN ..., must be listed in the header files of glibc. For the driver in kernel space, the definitions also must be listed in the corresponding Linux socket header files. Especially, both are for the testing programs. Back to the mentioned "LoRaWAN is not implemented in Linux kernel now". Could or should we add the definitions into corresponding kernel header files now, if LoRaWAN will be accepted as a subsystem in Linux?
