2019-12-02bonding: add/del secondary mac address callbackMatthew Smith2-0/+77
Type: feature Add a callback to the bond device class which allows a secondary mac address to be added/deleted. The desired operation is performed on all the hardware interfaces which belong to the bond interface. This allows virtual MAC addresses to be used on bond interfaces without requiring the hardware interfaces to have promiscuous mode enabled. When a hardware interface is added or removed from a bond, if there are any secondary MAC addresses configured on the bond, they are added or removed from the hardware interface.

2019-09-06bonding: add weight support for active-backup modeSteven Luong4-82/+258
Not all interfaces have the same characteristics within the bonding group. For active-backup mode, we should do our best to select the slave that performs the best as the primary slave. We already did that by preferring the slave that is local numa. Sometimes, this is not enough. For example, when all are local numas, the selection is arbitrary. Some slave interfaces may have higher speed or better qos than the others. But this is hard to infer. One rule does not fit all. So we let the operator to optionally specify the weight for each slave interface. Our primary slave selection rule is now 1. biggest weight 2. is local numa 3. current primary slave (to avoid churn) 4. lowest sw_if_index (for deterministic behavior) This selection rule only applies to active-backup mode which only one slave is used for forwarding traffic until it becomes unreachable. At that time, the next "best" slave candidate is automatically promoted. The slaves are sorted according to the preference rule when they are up. So there is no need to find the next best candidate when the primary slave goes down. Another good thing about this rule is when the down slave comes back up, it is selected as the primary slave again unless there is indeed a "better" slave than this down slave that were added during that period. To set the weight for the slave interface, do this after the interface is enslaved set interface bond <interface-name> weight <value> Type: feature Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I59ced6d20ce1dec532e667dbe1afd1b4243e04f9

2019-08-17bonding lacp: deleting virtual interface which was enslaved may cause crashSteven Luong3-26/+39
Virtual interfaces may be part of the bonding like physical interfaces. The difference is virtual interfaces may disappear dynamically. As an example, the following CLI sequence may crash the debug image create vhost-user socket /tmp/sock1 create bond mode lacp bond add BondEthernet0 VirtualEthernet0/0/0 delete vhost-user VirtualEhernet0/0/0 Notice the virtual interface is deleted without first doing bond delete. The proper order is to first remove the slave interface from the bond prior to deleting the virtual interface as shown below. But we should handle it anyway. create vhost-user socket /tmp/sock1 create bond mode lacp bond add BondEthernet0 VirtualEthernet0/0/0 bond del VirtualEthernet0/0/0 <----- delete vhost-user VirtualEhernet0/0/0 The fix is to register for VNET_SW_INTERFACE_ADD_DEL_FUNCTION and remove the slave interface from the bond if the to-be-deleted interface is part of the bond. We check the interface that it is actually up before we send the lacp pdu. Up means both hw and sw admin up.

2019-01-23bond: packet drops on VPP bond interface [VPP-1544]Steven2-20/+21
We register callback for VNET_HW_INTERFACE_LINK_UP_DOWN_FUNCTION and VNET_SW_INTERFACE_ADMIN_UP_DOWN_FUNCTION to add and remove the slave interface from the bond interface accordingly. For static bonding without lacp, one would think that it is good enough to put the slave interface into the ective slave set as soon as it is configured. Wrong, sometimes the slave interface is configured to be part of the bonding without ever bringing up the hardware carrier or setting the admin state to up. In that case, we send traffic to the "dead" slave interface. The fix is to make sure both the carrier and admin state are up before we put the slave into the active set for forwarding traffic.

- Reduce per packet cost by buffering the output packet buffer indexes in the queue and process the queue outside the packet processing loop. - Move unnecessary variable initialization outside of the while loop. - There is no need to save the old interface if tracing is not enabled. Test result for 256 bytes packet comparison. Other packet size shows similar improvement.
