2019-09-06bonding: add weight support for active-backup modeSteven Luong1-76/+198
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 Luong1-3/+3
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]Steven1-3/+5
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.

2018-04-24lacp: deleting the bond subinterface may cause lacp to lose the partner ↵Steven1-9/+1
[VPP-1251] Problem: When the bond subinterface is removed, it was observed that we lost the lacp partner. Show hardware shows rx counter goes up, but show interface does not for the slave interfaces. Cause: We reset the interface promiscuous mode when the bond subinterface is deleted. This causes dpdk not to accept any packet. Leave the interface in promiscuous mode fixes the problem. Other fixes: There are few places we use hw_if_index as if they are sw_if_index. But they don't necessarily have the same value. As soon as a subinterface is created, they start to diverge. The fix is to use the correct API for the hw_if_index and sw_if_index.

2018-04-13bond: ping fails between l2 BD [VPP-1238]Steven1-15/+33
In dpdk based bonding, when the bond interface is configured for l2, it automatically sets the bond interface to promiscuous mode and sets rx redirect to ethernet-input. This allows traffic to be bridged to non compute node facing interface when it is received from the compute node interface. For native vpp bonding, we need to do similar things. When the bond interface is configured for l2, we set the slave interfaces to promiscuous mode and set rx redirect to ethernet-input because dpdk does not know anything about the bond interface. Likewise, when a new interface is enslaved, we also need to do the same thing if the bond interface has already been configured for l2.

2018-03-30bond: show trace causes a crash if the interface is deletedSteven1-3/+14
For the debug image, if the interface is removed and the trace was collected prior to the interface delete, show trace may cause a crash. This is because vnet_get_sw_interface_name and vnet_get_sup_hw_interface are not safe if the interface is deleted. The fix is to use format_vnet_sw_if_index_name if all we need is to get the interface name in the trace to display. It would show "DELETED" which is better than a crash.

2018-03-21bond: Add bonding driver and LACP protocolSteven1-0/+706
Add bonding driver to support creation of bond interface which composes of multiple slave interfaces. The slave interfaces could be physical interfaces, or just any virtual interfaces. For example, memif interfaces. The syntax to create a bond interface is create bond mode <lacp | xor | acitve-backup | broadcast | round-robin> To enslave an interface to the bond interface, enslave interface TenGigabitEthernet6/0/0 to BondEthernet0 Please see src/plugins/lacp/lacp_doc.md for more examples and additional options. LACP is a control plane protocol which manages and monitors the status of the slave interfaces. The protocol is part of 802.3ad standard. This patch implements LACPv1. LACPv2 is not supported. To enable LACP on the bond interface, specify "mode lacp" when the bond interface is created. The syntax to enslave a slave interface is the same as other bonding modes.
