2017-10-26Fix multicast packet reception.Michael Borokhovich2-16/+23
This commit adds the 224.0.0.0/24 entry to the mfib, making it possible to receive multicast packets. Previously, multicast packets would not be received because the entry was added to the unicast fib and not mfib.

2017-10-09[router] Remove call to vlib_buffer_chain_validateJeff Shaw1-2/+0
The vlib_buffer_chain_validate() function was removed from VPP. To avoid referencing an undefined symbol, this commit removes the function call. Change-Id: I53f911a7d7b3d6121b8a4a0768b259af20730686 Signed-off-by: Jeff Shaw <jeffrey.b.shaw@intel.com>
2017-10-09[router] Set VLIB_RX metadata to valid sw_if_indexJeff Shaw1-1/+1
In normal cases, some multicast frames from the control plane are dropped by VPP before being sent. We were not setting the VLIB_RX interface to a valid sw_if_index, causing a segmentation fault when updating counters in the process_drop node.

2016-10-04[router] IPv6 support and refactoring.Jeff Shaw7-692/+1173
This change adds support for IPv6 while refactoring most of the original plugin code in the following ways. - Adhere to vpp style guidelines. - Split the netlink, node, and tap processing into separate files named with a "tap_inject" prefix which more accurately represents the functionality. - Implement our own tap management and rx/tx. This is to reduce the overhead of passing packets in and out of vnet tap devices, in favor of directly reading/writing from the tap. - Change how nodes work. Now we have neighbor, rx, and tx nodes. The neighbor node sends ARP replies and ICMP6 neighbor advertisements to the arp-input and icmp6-neighbor-solicitation nodes, respectively, before also injecting the packet to the host, making it possible for both vpp and the host network stack to resolve the next hop. The tx node injects packets into the host by writing to the tap. The rx node reads packets from the tap and sends them on its associated data plane interface. - Simplify the CLI. Instead of creating taps specifically for a given interface we create a tap for all of the Ethernet interfaces with the "enable tap-inject" CLI command. The interfaces are named with a "vpp" prefix, i.e. "vpp0". Also add a "disable tap-inject" option. - Provide ability to enable at configuration time with the tap-inject { enable } stanza.

2016-08-18[router] Support UDP protocol.Jeff Shaw1-0/+18
Register an IP protocol handler for UDP. When a UDP packet arrives on a tapped interface configured for UDP, the packet is injected on the input device's respective tap. commit f560a490c already adds support for directing multicast packets to the tap device.

2016-08-12[router] Handle initial tap link state.Jeff Shaw1-2/+37
When an interface is tapped, the tap inherits the link state of the underlying device. Also, the hw vector was being resized in the time between getting the interface and when the hw_address was referenced, leading to a segmentation fault. Resolve the issue by saving the mac address contents on the stack before passing to other functions.

2016-08-08[router] Link state eventsElza Mathew1-0/+47
This patch introduces a method to listen to link state events. The method invokes callback functions to set the interface flags. Change-Id: I284bc5dd92a38c91f093d6709fb43b6b5ae57c56 Signed-off-by: Elza Mathew <elza.mathew@intel.com>
2016-08-03[router] Support igmp and ospf multicast.Jeff Shaw1-3/+62
When requested, inject IGMP and OSPF packets with a multicast address of 224.0.0.0/24 to the respective tap. Change-Id: I2763e3df1929d12bd7b5a68bca51f83febc63b28 Signed-off-by: Jeff Shaw <jeffrey.b.shaw@intel.com>
2016-08-02[router] Correctly handle per-interface protocolsJeff Shaw1-46/+70
Previously, if one interface were configured to inject a protocol, then all interfaces would inject the protocol. In other words, if iface 1 were configured for arp,icmp4 and iface 2 were configured for arp,icmp4,tcp, then iface 1 would erroneously inject tcp. This commit fixes the above behavior such that each packet is compared with the protocols enabled for the interface before injecting.
