eBPF

eBPF allows developers to dynamically load custom code into the Linux kernel, enhancing capabilities for observability, tracing, and security without modifying the kernel itself. By distinguishing between kernel space and user space, the post underscores the advantages of running code with kernel-level privileges. It explores various methods for executing custom logic in the kernel, including Kernel Modules, adding programs via a kernel patch, using Kernel Hooks, employing System Tap and DTrace, and leveraging eBPF. eBPF stands out for its efficiency, security, and support for high-level languages.
