2018-04-17vhost: show vhost-user <interface> may crash [VPP-1242]Steven1-0/+7
show vhost-user <interface> may cause a crash if interface is semi-bogus. Semi-bogus means it is a known vpp interface which has a hw_if_index, but it is bogus because it is not a vhost-user interface. The fix is to add a check to reject non vhost-user interface for the command. Change-Id: I63f1e8bfbf46f5ec4c30f9fb3546982b63cd7cc5 Signed-off-by: Steven <sluong@cisco.com>

2018-04-16Implement ip_probe_neighbor APIJohn Lo2-9/+63
Add API support similar to VPP CLI "ip probe-neighbor" except API call is asynch and will not wait, as the CLI does, for address resolution of probed neighbor. The API client can use the APIs want_ip4_arp_events or want_ip6_nd_events to get notified of the desired address resolution event.

2018-04-13bond: ping fails between l2 BD [VPP-1238]Steven4-15/+91
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.

2018-04-10Make IPsec tunnel intf work with IPv4 output featuresMatthew Smith2-0/+13
With no IPv4 output features on an IPsec tunnel inferface, when packets are forwarded to that interface, they reach the ipsec-if-output node via the output_node_index on the hw interface and they are handled correctly. When an IPv4 output feature (e.g. output ACL, outbound NAT) is enabled on an IPsec tunnel interface, outbound IPsec stops working for that interface. The last node in the ip4-output feature arc is interface-output. From there a packet is sent to ipsec<N>-output, and then ipsec<N>-tx. The tx function for an IPsec tunnel interface that is called by ipsec<N>-tx is a dummy that doesn't do anything except write a warning message. Enable a feature on the interface-output feature arc for an IPsec tunnel interface so the ipsec-if-output node is reached from the interface-output node.

2018-03-30bond: show trace causes a crash if the interface is deletedSteven3-13/+32
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.

coverity complains about statements in function A function A { x % vec_len (y) } because vec_len (y) is a macro and may return 0 if the pointer y is null. But coverity fails to realize the same statement vec_len (y) was already invoked and checked in the caller of function A and punt if vec_len (y) is 0. We can fix the coverity warning and shave off a few cpu cycles by caching the result of vec_len (y) and pass it around to avoid calling vec_len (y) again in multiple places.

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.
