The Linux Kernel networking stack processes incoming packets arriving at Layer 2 to the network layer and then passes for local delivery to the transport layer protocols listening to TCP or UDP sockets. Any packets not destined to the local system are sent back down the stack for transmission. The kernel does not handle anything above Layer 4.
The networking subsystem is not an essential component of an operating system kernel (the Linux kernel can be compiled without networking support). It is, however, quite unlikely for a computing system (or even an embedded device) to have a non-networked operating … Monitoring and Tuning the Linux Networking Stack Jun 22, 2016 Linux Networking Subsystem - Technology Focused Hub The Linux Kernel networking stack processes incoming packets arriving at Layer 2 to the network layer and then passes for local delivery to the transport layer protocols listening to TCP or UDP sockets. Any packets not destined to the local system are sent back down the stack for transmission. The kernel does not handle anything above Layer 4 SDN dilemma: Linux kernel networking vs. kernel bypass Linux kernel stack technologies such as eBPF and the Traffic Classifier hold the promise of allowing SmartNIC vendors like Netronome to stick to the Linux kernel networking stack and allow data

The type of firewall provided by this kernel support is called a "packet filter", which means that it can reject individual network packets based on type, source, destination etc.
