2019-08-28lacp: mark is_mp_safe for show and dump binary APISteven Luong1-0/+1
show and dump binary APIs for lacp neighbors are running in the same thread as the create and delete interface. There is no need for barrier lock. Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: Id584bd7408210fcc23b464ef2084f11f88bca58b
2019-08-17bonding lacp: deleting virtual interface which was enslaved may cause crashSteven Luong1-3/+4
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.

2019-06-07lacp: create lacp-process on demandSteven Luong1-0/+2
Create lacp-process when the very first slave interface is added to the bond. Log an event message when lacp-process starts/stops. Be mindful when lacp-process is signalled to stop. Type: refactor Change-Id: I79e10e0a2a385a21a52ae5b8735f24631fdba293 Signed-off-by: Steven Luong <sluong@cisco.com>
2019-04-03lacp: passive mode support [VPP-1551]Steven Luong1-3/+26
By definition, passive mode means the node does not start sending lacp pdu until it first hears from the partner or remote. - Rename ptx machine's BEGIN state to NO_PERIODIC state. - Put periodic machine in NO_PERIDOIC state when the interface is enabled for lacp. ptx machine will transition out of NO_PERIODIC state when the local node hears from the remote or when the local node is configured for active mode. - Also add send and receive statistics for debugging.

2018-04-24lacp: deleting the bond subinterface may cause lacp to lose the partner ↵Steven1-13/+7
[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.

2018-03-21bond: Add bonding driver and LACP protocolSteven1-0/+393
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.
