The Hedge 58: Michael Kehoe and eBPF

Most packet processing in Linux “wants” to be in the kernel. The problem is that adding code to the kernel is a painstaking process because a single line of bad code can cause havoc for millions of Linux hosts. How, then, can new functionality be pushed into the kernel, particularly for packet processing, with reduced risk? Enter eBPF, which allows functions to be inserted into the kernel through a sort of “lightweight container.”

Michael Kehoe joins Tom Ammon and Russ White to discuss eBPF technology and its importance.
