tracing: Why is a packet being dropped or a request rejected. The policy tracing framework allows to trace the policy decision process for both, running workloads and based on arbitrary label defini�ons. Integrated capability of the Linux kernel to accept compiled bytecode that is run at various hook / trace points within the kernel. Cilium compiles BPF programs and has the kernel run them at key points in way to verify if and what policy rules apply between two endpoints. We can use the cilium policy trace to simulate a policy decision between the source and des�na�on endpoints. We will use the example

community interest. It is planned for removal in 1.12. The in-pod Cilium CLI command cilium policy trace has been deprecated in favor of approaches using the Network Policy Editor [https://app.networkpolicy BPF_MAP_TYPE_PROG_ARRAY, BPF_MAP_TYPE_PERF_EVENT_ARRAY, BPF_MAP_TYPE_CGROUP_ARRAY, BPF_MAP_TYPE_STACK_TRACE, BPF_MAP_TYPE_ARRAY_OF_MAPS, BPF_MAP_TYPE_HASH_OF_MAPS. For example, BPF_MAP_TYPE_PROG_ARRAY is an and early throw an error to the user. Helper functions such as trace_printk() can be worked around as follows: static void BPF_FUNC(trace_printk, const char *fmt, int fmt_size, ...); #ifndef printk #
