Detailed Description

This class manages an operative state of VxLAN logical routers (LR) defined via Config logical-router element. The operative state include bonds between LRs, virtual networks, VRFs and corresponding routes which support connectivity between networks connected to a LR.

Given a logical router (LR), there is precisely 1 routing virtual network (VN) and a routing VRF table associated with it and zero or more bridge VNs (and corresponding VRF tables) whose states are manipulated by VxlanRoutingManager using routes leaking process. Routes leaking is a routing tables bi-directional manipulation process during which:

new VM interface routes arising in the bridge VRF tables are being transferred into the routing VRF table associated with the LR (forward propagation of routes);
new routes arising in the routing VRF table are redistributed among the bridge VRF tables associated with the LR (backward propagation of routes);
deletion of created routes in the routing or a bridge VRF leads to the deletion of the corresponding created routes in other VRF tables associated with the LR.

In a nutshell, routes leaking is a kind of data synchronization process between several routing tables.

A bridge virtual network is a basic element in OpenSDN that manages network connectivity between several VMs within a broadcast domain. A routing virtual network is a technical virtual network associated with a LR and providing connectivity between several bridge virtual networks attached to (associated with) the LR.

The information about an LR is loaded into (or unloaded from) the Agent’s operative DB when the processing of a corresponding IF-MAP node changes triggers notifications for associated tables: the interfaces tables (InterfaceTable class), the virtual networks table (VnTable class) and the VRFs tables (VrfTable class). The changes to the IF-MAP nodes arise due to such events as a connection of a virtual network with an LR (or a disconnection of a VN from an LR), appearance of a first VM connected to an LR via a bridge network or a destruction of a last VM (connected to an LR) on a hypervisor. VxlanRoutingManager links these notifications with its member functions: VxlanRoutingManager::VmiNotify, VxlanRoutingManager::VnNotify and VxlanRoutingManager::VrfNotify and they are called VmiNotify, VnNotify and VrfNotify for brevity.

Due to concurrency mechanisms, these functions can run in various order. However, only specific order guarantees lack of inconsistencies in the VxlanRoutingManager data describing state of an LR:

if an LR is being created or updated (e.g., a bridge network is being attached to it), then the correct notifications processing order is VmiNotify, VnNotify and VrfNotify, in this case routes leaking functions which are called by RouteNotify member of VxlanRoutingManager will not start execution until all information from IF-MAP is not correctly transferred into the operative DB;
if an LR is being destroyed (or a bridge network is being detached from it), then the situation is not so obvious, because (a) on the one hand, VrfNotify should be called first to prevent unexpected routes leaking from the disconnected or destroyed bridge virtual network, however this breaks normal event-based mechanism of routes update in the LR's bridge networks due to changes in the LR's routing network (since RouteNotify handler will be disconnected) therefore, (b) the only second viable option is when VnNotify is called first.

The preferred order of execution for functions VrfNotify, VmiNotoify and VnNotify cannot be specified explicitly from VxlanRoutingMananger, since it is controlled by (a) arrival of IF-MAP information on a hypervisor node from a controller and (b) by policies of Agent's operative DB. For some cases, the correctness of execution is guaranteed by the order of IF-MAP nodes processing, in some cases, it is guaranteed by additonal calls inside VxlanRoutingManager.

VxlanRoutingManager acts as a kernel module in some sense: it has several member functions acting as an entry point and providing service to its caller: an information about the current state of the module, modification of the internal state, modifiction of external state (routes advertisement). These entry points are:

VxlanRoutingManager::VxlanRoutingManager, initializes the module, modifies only the internal state;
VxlanRoutingManager::Register: sets/resets handlers for change events in VmiTable, VrfTable and VnTable, modifies only the internal state;
VxlanRoutingManager::VmiNotify: links a VN with a VMI connecting the latter with an LR, modifies the external state (VnEntry and VmInterface states declared in VxlanRoutingManager) and is called whenever a VMI is being attached to an LR (or detached from an LR);
VxlanRoutingManager::VnNotify: establishes (updates) a mapping between an LR and VNs attached to the LR, initiates traversing of the routing and bridge VRF tables to copy (leak) routes between them, modifies the internal and external states and is called whenever a VN is modified;
VxlanRoutingManager::VrfNotify: links VxlanRoutingManager member functions with changes in a modified bridge VN and routing VN routing tables, modifies only the internal state;
VxlanRoutingManager::RouteNotify: propagates locally-originated routes (interface or interface composites) from bridge VRF Inet tables into the routing VRF Inet table associated previously with an LR;
VxlanRoutingManager::XmppAdvertiseEvpnRoute: advertises an external EVPN Type 5 route that came from controller via BGP/XMPP;
VxlanRoutingManager::IsVxlanAvailable: returns true if VxLAN is available;
VxlanRoutingManager::IsRoutingVrf: returns true if the given VRF table object is a VxLAN routing VRF table.

The internal state of VxlanRoutingManager is defined by a map between an LR UUID and virtual networks / VRF tables, associated with this LR. The map is defined in VxlanRoutingVrfMapper class and stored as std::map for a pair of {boost::uuids::uuid, VxlanRoutingVrfMapper::RoutedVrfInfo}, where VxlanRoutingVrfMapper::RoutedVrfInfo stores:

a pointer to a VnEntry object containing description of the routing VN associated with the LR;
a list of pointers to VnEntry objects containing description of bridge VNs associated with the LR;
an array of names of VrfEntry objects containing description of bridge and routing VRF tables linked with the corresponding VNs. In addition, VxlanRoutingVrfMapper contains a reverse map, that determines an LR UUID by a pointer to an VnEntry object, associated with an LR as a bridge or a routing VN.

The external state, which is modified by VxlanRoutingManager, is characterized by:

VRF tables (inet and EVPN) of bridge and routing virtual networks;
operative DB entries states (VxlanRoutingVnState, VxlanRoutingVmiState, VxlanRoutingState) which are associated with a VN, a VRF table or a VMI to store additional information needed by VxlanRoutingManager.

Since the aforementioned VxlanRoutingManager entry points are executed in tasks with the same task code and task data ID (see Task class), their execution is mutually exclusive, i.e., they cannot run in parallel, but the order of their execution is not predetermined.
