Tracing Summit 2023 - Programmable dynamic tracing on Linux with DTrace using BPF

The implementation of DTrace for Linux based on BPF as a programmable dynamic tracing solution is nearing feature parity with legacy versions that required invasive kernel patches. The talk will present the current state of the project, and highlight creative solutions to get around kernel limitations. We will also present some problem areas that we found to open conversations about potential solutions.
