2017-03-07DHCP Multiple Servers (VPP-602, VPP-605)Neale Ranns10-176/+440
Multiple DHCP (4 and/or 6) servers can be added and removed through multiple calls to the 'set dhcp server' API. All 4/6/ discover/solicit messages will then be replicated to all servers in the list. The expectation is that the servers/system is configured in such a way that this is viable. If VSS information is providied for the clinet VRF which also has multiple servers configured, then the same VSS information is sent to each server. Likewise the source address of packets sent to from VPP to each server is the same. Change-Id: I3287cb084c84b3f612b78bc69cfcb5b9c1f8934d Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-03-03Implement a loopback instance allocation scheme.Jon Loeliger2-12/+117
To support creating loopback interfaces with a specific instance number, a new CREATE_LOOPBACK_INSTANCE API call with flag is_specified and value user_instance is introduced. Presumably the existing CREATE_LOOPBACK API message will be obsoleted and revmoved. The VAT cli commands can now mention and format the new field as 'instance %d' data. If no instance number is named, the old call CREATE_LOOPBACK is used to maintain backward compatibility. However, if the instance is named, the new CREATE_LOOPBACK_INSTANCE message will be used. Both the dynamically allocated and user-requested instance number are tracked in a bitvector. If is_specified is 0, the next free instance will be used.. A request for a specific instance number will be granted if it is available. On error, the value ~0 is returned.

2017-03-03VPP-651: Ensure sw_if_index to node mapping for L2 output path is only done ↵Andrew Yourtchenko3-3/+17
via l2output_main.next_nodes Before this commit, several output features that happen to be the last in the list of features to be executed, send the packets directly to <interfaceName>-output. To do this, they use l2_output_dispatch, which builds a list of sw_if_index to next index mappings. When interfaces are deleted and the new interfaces are created, these mappings become stale, and cause the packets being sent to wrong interface output nodes. This patch (thanks John Lo for the brilliant idea!) adds a feature node "output", whose sole purpose is dispatching the packets to the correct interface output nodes. To do that, it uses the l2output_main.next_nodes, which is already taken care of for the case of the sw_if_index reuse, so this makes the dependent features all work correctly. Since this changes the packet path, for the features that were always the last ones it has triggered a side problem of the output feat_next_node_index not being properly initalized. These two users are l2-output-classify node and the output nodes belonging to the acl-plugin. For the first one the less invasive fix is just to initialize that field. For the acl-plugin nodes, rewrite the affected part of the code to use feat_bitmap_get_next_node_index since this is essentially what the conditional in l2_output_dispatch does, and fix the compiler warnings generated. This fix was first made in stable/1701 under commit e7dcee4027854b0ad076101471afdfff67eb9011.

Removed a fair number of "BUG" message handlers, due to conflicts with actual message handlers in api_format.c.

With VPP-651, the L2 output config with L2-tag rewrite was not cleared when a sub-interface is deleted. Subsequently, when the same sw_if_index was reused for another interface, the L2 output config with L2-tag rewrite remained on the new interface. On deleting a (sub-)interface which is in L2 mode, it will be changed to L3 mode first to clear any L2 config. The L2 to L3 mode change path did address L2 input config cleanup. It is now fixed to also clear L2 output config. Change-Id: I3352a89d92e1b27340a5adcf75bbaa01a5050c29 Signed-off-by: John Lo <loj@cisco.com>
