2016-10-07lib: add "qobj" object-ID infrastructureDavid Lamparter
This adds 64-bit random identifiers as "safe pointers" which are also type-tracked / can have type-specific extension methods. This will be used by both the CLI (to keep safe references while in config editing mode) as well as the Cap'n Proto code (to hand out pointers to the user in a safe way and add per-type handlers) Signed-off-by: David Lamparter <equinox@opensourcerouting.org>

2016-10-03bgpd: add L3/L2VPN Virtual Network Control featureLou Berger
This feature adds an L3 & L2 VPN application that makes use of the VPN and Encap SAFIs. This code is currently used to support IETF NVO3 style operation. In NVO3 terminology it provides the Network Virtualization Authority (NVA) and the ability to import/export IP prefixes and MAC addresses from Network Virtualization Edges (NVEs). The code supports per-NVE tables. The NVE-NVA protocol used to communicate routing and Ethernet / Layer 2 (L2) forwarding information between NVAs and NVEs is referred to as the Remote Forwarder Protocol (RFP). OpenFlow is an example RFP. For general background on NVO3 and RFP concepts see [1]. For information on Openflow see [2]. RFPs are integrated with BGP via the RF API contained in the new "rfapi" BGP sub-directory. Currently, only a simple example RFP is included in Quagga. Developers may use this example as a starting point to integrate Quagga with an RFP of their choosing, e.g., OpenFlow. The RFAPI code also supports the ability import/export of routing information between VNC and customer edge routers (CEs) operating within a virtual network. Import/export may take place between BGP views or to the default zebera VRF. BGP, with IP VPNs and Tunnel Encapsulation, is used to distribute VPN information between NVAs. BGP based IP VPN support is defined in RFC4364, BGP/MPLS IP Virtual Private Networks (VPNs), and RFC4659, BGP-MPLS IP Virtual Private Network (VPN) Extension for IPv6 VPN . Use of both the Encapsulation Subsequent Address Family Identifier (SAFI) and the Tunnel Encapsulation Attribute, RFC5512, The BGP Encapsulation Subsequent Address Family Identifier (SAFI) and the BGP Tunnel Encapsulation Attribute, are supported. MAC address distribution does not follow any standard BGB encoding, although it was inspired by the early IETF EVPN concepts. The feature is conditionally compiled and disabled by default. Use the --enable-bgp-vnc configure option to enable. The majority of this code was authored by G. Paul Ziemba <paulz@labn.net>. [1] http://tools.ietf.org/html/draft-ietf-nvo3-nve-nva-cp-req [2] https://www.opennetworking.org/sdn-resources/technical-library Now includes changes needed to merge with cmaster-next.

2016-09-19*: split & distribute memtypes and stop (re|ab)using lib/ MTYPEsDavid Lamparter
This is a rather large mechanical commit that splits up the memory types defined in lib/memtypes.c and distributes them into *_memory.[ch] files in the individual daemons. The zebra change is slightly annoying because there is no nice place to put the #include "zebra_memory.h" statement. bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the library for its own use. This is bad practice and would break when the memtype are made static.

2016-09-09lib, vtysh: support multiple VRFs by using linux netnsFeng Lu
We realize VRFs with linux netns by default. The main job is to associate a VRF with a netns. Currently this is done by the configuration: [no] vrf N netns <netns-name> This command is also available in vtysh and goes to only zebra, because presently only zebra supports multiple VRF. A file descriptor is added to "struct vrf". This is for the associated netns file. Once the command "vrf N netns NAME" is executed, the specified file is opened and the file descriptor is stored in the VRF N. In this way the association is formed. In vrf_socket(), we first switch to the specified VRF by using the stored file descriptor, and then can allocate a socket which is working in the associated netns.

2016-07-26lib: Free memory correctly when braces used in parserDon Slice
When braces (optional parameters) are used in the quagga parser, there was a small leak on every iteration. Since this construct is primarily used in the configuation process rather than show commands, it was not readily apparent. With the addition of the "show ip bgp {json}" form of the commands, each time one was run, memory was leaked.
