Changes
This PR features an experimental service mapping that combines the kubeapi and the UID extraction from cgroups. The extracted data are combined in a HashMap for O(1) access. The aim is to give more information such as the pod name to better identify the source of a TCP packet (can also have better precision than the bpf_get_current_comm() function that we are currently using)
Changes:
- added unit tests
- added tcp_analyzer function to extract relevant information from the tcp_v4_connect kprobe
- added a new ClusterRole to allow pod info extraction from the kubeapi
- refactored map pinning function
Testing
Docker image:
cortexflow-identity:0.1.1-cgroup_scannerv_exp
