Last time we analyzed IP fragmentation reassembly, this time we will analyze IP fragmentation. First, we need to understand why fragmentation is necessary. For example, in Ethernet, the CSMA/CD protocol (implemented by the network card) specifies a maximum (MTU) and minimum size for link layer packets (excluding the MAC header, but in this kernel version, … Read more
Introduction: The purpose of this content is similar to the previous article, but the starting point is different. Our plan is to read version information from a file instead of setting it in CMakeLists.txt. The goal of storing the version in a separate file is to allow other build frameworks or development tools to use … Read more
