SSL/TLS adoption in the Cloud Native environments is growing rapidly. While great for security, the encryption in such environments pose a unique challenge for observability tools. Many traffic sniffing tools can only collect the encrypted data, which is of limited value to the application developer. Important attributes like the operation, the endpoint and the payload are undecipherable. To truly help in the troubleshooting process, application developers need to be able to see these messages and their contents. In this talk, we present how eBPF can be used to tracing SSL/TLS connections. The method we present is used by tools like BCC’s sslsniff and Pixie’s protocol tracer. Specifically, we cover how eBPF uprobes can be attached to popular SSL/TLS libraries, including OpenSSL, BoringSSL and goTLS. We show how eBPF enables us to collect clear text data directly from the TLS library, while discussing the challenges of tracing dynamically vs statically linked TLS libraries. Finally, we also present how this feature could help with improving application observability at some of the largest engineering organizations without disrupting their production environment.
