 # Expanding eBPF Compile Once, Run Everywhere(CO-RE) to Userspace Compatibility 
 
+> Yusheng 
+
 eBPF, short for extended Berkeley Packet Filter, is a powerful and versatile technology used in modern Linux systems. It allows for the running of sandboxed programs in a virtual machine-like environment within the kernel, providing a safe way to extend the capabilities of the kernel without the risk of crashing the system or compromising security.
 
 Co-RE, standing for 'Compile Once, Run Everywhere', tackles the critical issue of eBPF program compatibility across diverse kernel versions. This feature allows eBPF programs to run on various kernel versions without the need for recompilation, simplifying deployment and maintenance.
