Introduction Hey there, tech enthusiasts! If you've been following along, you’re probably as a bit more familiar on what eBPF is and how it works. If not, do not fret. You can go an read my first post, The magic of eBPF I , where we’ve seen how this technology lets us peer into the depths of the Linux kernel, optimize performance, and bolster security. But like all powerful tools, eBPF isn’t all sunshine and rainbows. Welcome to Part 2 of our eBPF series, where we delve into the flip side of this shiny new toy: the Challenges and Limitations . We’ll talk about the steep learning curve you might face, issues of compatibility with different kernel versions, potential performance overheads , and the security considerations you need to keep in mind when working with eBPF. Consider this your eBPF bootcamp, preparing you for the real-world hurdles you might encounter. Challenges and Limitations Learning curve complexity ...
