Thanks for sharing my site!
I've been thinking about building a platform like this for a while, and it was quite fun to build.
Let me know if you have questions or ideas for new exercises.
Thanks for making this, looking forward trying it out!
This is really cool.
Are you planning to add "lessons" related to deployment? For example, using libbcc vs CO-RE?
I wanted to add all kind of exercises, but I'm not sure what's a good way of presenting a deployment exercise.
On libbcc specifically, I'm not sure it's worth it, CO-RE / BTF is where things are heading, and any reasonably new kernel supports it (<5 years old)
For all it's innovative way of kernel programming, isn't eBPF a huge attack surface? Even a paradise for rootkit devs, perfectly able to hide using eBPF features.
Nice, always wanted to get my hands on eBPF and this looks like a good way to try it out. Thanks!
