Frequently Asked Questions
Q:What is eBPF?
eBPF stands for extended Berkeley Packet Filter, a technology that allows the Linux kernel to execute user-defined programs in response to events.
Q:How does eBPF enhance kernel programmability?
eBPF enhances kernel programmability by enabling developers to write custom code that can run in the kernel space without needing to modify the kernel source code.
Q:What are some use cases for eBPF?
Use cases for eBPF include network traffic filtering, performance monitoring, security enforcement, and tracing system calls.
Q:Is eBPF safe to use in production environments?
Yes, eBPF is designed with safety features that prevent user-defined programs from crashing the kernel, making it suitable for production use.
Q:What programming languages can be used to write eBPF programs?
eBPF programs are typically written in C, but there are also higher-level languages and tools that can compile to eBPF bytecode.
