Up until now we only used hash-based tables in the device, but we are going to use the linear table for remote routes adjacency lists.

Listen to any NEIGH_UPDATE events sent and program the device accordingly. If NUD state is VALID and neighbour isn't yet offloaded, then program it into the device's table. Otherwise, just edit its parameters. If NUD state machine transitioned neighbour out of VALID state and it's present in the device's table, then remove it. Note that the device is programmed in delayed work, as the netevent notification chain is atomic and prevents us from going to sleep.

As previously explained, the driver should periodically poll the device for neighbours activity according to the configured DELAY_PROBE_TIME. This will prevent active neighbours from staying in STALE state for long periods of time. During init configure the polling interval according to the DELAY_PROBE_TIME used in the default table. In addition, register a netevent notification block, so that the interval is updated whenever DELAY_PROBE_TIME changes. Using the computed interval schedule a delayed work, which will update the kernel via neigh_event_send() on any active neighbour since the last delayed work.

We need to hold some private data for every neigh entry. It would be possible to do it using neigh_priv_len/ndo_neigh_construct/ ndo_neigh_destroy however only for the port device itself. That would not work for stacked devices like bridge/team/bond. So introduce a private neigh table. Hook onto ndos neigh_construct/destroy and add/remove table entry according to that.

As with the previously introduced L3 interfaces, listen to 'inetaddr' notifications sent for bridges devices configured on top of the port netdevs and create / destroy router interfaces (RIFs) accordingly. This also includes VLAN devices configured on top of the VLAN-aware bridge. The RIFs will be destroyed either when the last IP address is removed or when the underlying FID is is destroyed.

由 Ido Schimmel 提交于
Before introducing support for L3 interfaces on top of the VLAN-aware bridge we need to add some missing infrastructure. Such an interface can either be the bridge device itself or a VLAN device on top of it. In the first case the router interface (RIF) is associated with FID 1, which is created whenever the first port netdev joins the bridge. We currently assume the default PVID is 1 and that it's already created, as it seems reasonable. This can be extended in the future. However, in the second case it's entirely possible we've yet to create a matching FID. This can happen if the VLAN device was configured before making any bridge port member in the VLAN. Prevent such ordering problems by using the VLAN device's CHANGEUPPER event to configure the FID. Make the VLAN device hold a reference to the FID and prevent it from being destroyed even if none of the port netdevs is using it.

Up until now we only supported bridged interfaces. Packets ingressing through the switch ports were either classified to FIDs (in the case of the VLAN-aware bridge) or vFIDs (in the case of VLAN-unaware bridges). The packets were then forwarded according to the FDB. Routing was done entirely in slowpath, by splitting the vFID range in two and using the lower 0.5K vFIDs as dummy bridges that simply flooded all incoming traffic to the CPU. Instead, allow packets to be routed in the device by creating router interfaces (RIFs) that will direct them to the router block. Specifically, the RIFs introduced here are Sub-port RIFs used for VLAN devices and port netdevs. Packets ingressing from the {Port / LAG ID, VID} with which the RIF was programmed with will be assigned to a special kind of FIDs called rFIDs and from there directed to the router. Create a RIF whenever the first IPv4 address was programmed on a VLAN / LAG / port netdev. Destroy it upon removal of the last IPv4 address. Receive these notifications by registering for the 'inetaddr' notification chain. A non-zero (10) priority is used for the notification block, so that RIFs will be created before routes are offloaded via FIB code. Note that another trigger for RIF destruction are CHANGEUPPER notifications causing the underlying FID's reference count to go down to zero. This can happen, for example, when a VLAN netdev with an IP address is put under bridge. While this configuration doesn't make sense it does cause the device and the kernel to get out of sync when the netdev is unbridged. We intend to address this in the future, hopefully in current cycle. Finally, Remove the lower 0.5K vFIDs, as they are deprecated by the RIFs, which will trap packets according to their DIP.

We are just about to introduce router interfaces (RIFs), but before that we need to be able update the device with the correct RIF attributes whenever they change for the netdev the RIF is backing. Two such attributes are MTU and MAC. The MAC is used both to set the source MAC of packets egressing from the RIF and also to program an FDB rule that will direct packets to the router block. Use the existing netdevice notification block and respond to CHANGEADDR and CHANGEMTU accordingly. Store both attributes in the RIF struct in case we need to revert to old attributes following a failed update.
