WebeBPF (often aliased BPF) is a technology that can run sandboxed programs in a privileged context such as the operating system kernel. It is used to safely and efficiently extend the capabilities of the kernel at runtime without requiring to change kernel source code or load kernel modules. Safety is provided through an in-kernel verifier which performs static … Webthe eBPF bytecode to the programmable hardware’s machine code. Maps may also be ofﬂoaded as the hardware contains 2-8GB DRAM. The ﬁrmware is then able to return processed frames along with metadata and statistics to the host.
