The xfrpc project is a lightweight implementation of the FRP client written in C language for OpenWRT and IoT systems. It is designed to provide an efficient solution for resource-constrained devices such as OpenWRT routers and IoT devices, which often have limited ROM and RAM space.
feat: curing static library environment, libevent is 2.1.10-stable, openssl is 1.1.0f, json-c is 0.16 and add low level linux kernel support.
