Talks

2018	Spying on the Linux kernel for fun and profit
45'	Do you ever wonder what the kernel is doing while your code is running? This talk will explore some methodologies and techniques (eBPF, ftrace, etc.) to look under the hood of the Linux kernel and understand what it’s actually doing behind the scenes. This talk explores methodologies that allow to take a look “live” at kernel internal operations, from a network perspective, to I/O paths, CPU usage, memory allocations, etc., using in-kernel technologies, like eBPF and ftrace. Understanding such kernel internals can be really helpful to track down performance bottlenecks, debug system failures and it can be also a very effective way to approach to kernel development.
