This patch changes the way we persist the data on disk when running Calico/VPP. Instead of using struc and binary format we transition to json files. Size should not be an issue as number of pods per node are typically low (~100). This will make troubleshooting easier and errors clearer when parsing fails. We thus remove the /bin/debug troubleshooting utility as the data format is not human readable. Doing this, we address an issue where PBL indexes were reused upon dataplane restart, as they were stored in a list. We now will use a map to retain the containerIP mapping. We also split the configuration from runtime spec in LocalPodSpec and add a step to clear it when corresponding VRFs are not found in VPP. Finally we address an issue where uRPF was not properly set up for ipv6. Signed-off-by: Nathan Skrzypczak <[email protected]>
