Debugging the BPF Virtual Machine Lorenzo Fontana October 28, 2020 ● Debugging is useful to understand how things work ● Sometimes, eBPF programs can’t even load ● I couldn’t find good resources on this this, so, here I am ● I break lots of eBPF programs ● The BPF Virtual machine is not easy to understand Why ? The BPF subsystem lives in the kernel AND The kernel can be debugged using gdb The

Innovation Projects DPUDirect DPU SIG DPUDirect creates a collaborative operating environment for services, enabling them to be easily offloaded and ported between hosts and DPUs. The feature includes of service code on the management plane is needed to ensure software compatibility and evolving services, as well as reducing component maintenance costs. Features The figure illustrates the architecture requirements of the management-plane processes, eliminating the need to split and reconstruct too many services.

is open source software for transparently securing the network connectivity between application services deployed using Linux container management platforms like Docker and Kubernetes. At the foundation built on top of Cilium and eBPF to enable deep visibility into the communication and behavior of services as well as the networking infrastructure in a completely transparent manner. By building on top eBPF powers. Hubble can answer questions such as: Service dependencies & communication map What services are communicating with each other? How frequently? What does the service dependency graph look like

is open source software for transparently securing the network connectivity between application services deployed using Linux container management platforms like Docker and Kubernetes. At the foundation often referred to as microservices, wherein a large application is split into small independent services that communicate with each other via APIs using lightweight protocols like HTTP. Microservices applications application traffic for security purposes as the port is utilized for a wide range of messages across services. An additional challenge is the ability to provide accurate visibility as traditional systems are
