A UDP-encap object that particiapates in the FIB graph and contributes
DPO to teh output chain. It thereofre resembles a tunnel but without the
interface. FIB paths (and henace routes) can then be created to egress
through the UDP-encap. Said routes can have MPLS labels, hence this also
allows MPLSoUPD.
Encap is uni-directional. For decap, one still registers with the UDP port
dispatcher.

To enable this, applications set the proxy flag in their attach requests
and pass the transport protocols they want to act as proxies for as part
of the attach options.
When proxy is enabled, session rules that point incoming packets to the
proxy app are addedd to the local and global session tables, if these
scopes are accessible to the app. In particular, in case of the former,
the rule accepts packets from all sources and all ports destined to the
namespace's supporting interface address on any port. While in case of
the latter, a generic any destination and any port rule is addedd.

This introduces 5-tuple lookup tables that may be used to implement
custom session layer actions at connection establishment time (session
layer perspective).
The rules table build mask-match-action lookup trees that for a given
5-tuple key return the action for the first longest match. If rules
overlap, ordering is established by tuple longest match with the
following descending priority: remote ip, local ip, remote port, local
port.
At this time, the only match action supported is to forward packets to
the application identified by the action.

- Global variables declared in header files without
the use of the 'extern' keword will result in multiple
instances of the variable to be created by the compiler
-- one for each different source file in which the
the header file is included. This results in wasted
memory allocated in the BSS segments as well as
potentially introducing bugs in the application.

Vat supports setting value for the parameter, but
'not_last' is ignored by ip_add_del_route handler,
so can be removed.
This patch
- updates ip.api,
- removes vat handlers
- updates vpp_papi_provider.py
(also mpls_route_add_del with unused not_last)

This reverts commit f9342023c19887da656133e2688a90d70383b0c5.
Reverting to unblock master. No idea why jjb +1ed this patch! On closer inspection it looks like it -1ed it and subsequently changed opinion. CSIT tests should be fixed before re-merging.

This patch is a plausible first-cut, suitable for initial testing by
vcl (host stack client library).
Main features;
- recursive name resolution
- multiple ip4/ip6 name servers
- cache size limit enforcement
- currently limited to 65K
- ttl / aging
- static mapping support
- show / clear / debug CLI commands
Binary APIs provided for the following:
- add/delete name servers
- enable/disable the name cache
- resolve a name
To Do list:
- Respond to ip4/ip6 client DNS requests (vs. binary API requests)
- Perf / scale tuning
- map pending transaction ids to pool indices, so the cache
can (greatly) exceed 65K entries
- Security improvements
- Use unpredictable dns transaction IDs, related to previous item
- Make sure that response-packet src ip addresses match the server
- Add binary APIs
- deliver raw response data to clients
- control recursive name resolution
- Documentation

Applications are now provided the option to select the namespace they
are to be attached to and the scope of their attachement. Application
namespaces are meant to:
1) constrain the scope of communication through the network by
association with source interfaces and/or fib tables that provide the
source ips to be used and limit the scope of routing
2) provide a namespace local scope to session layer communication, as
opposed to the global scope provided by 1). That is, sessions can be
established without assistance from transport and network layers.
Albeit, zero/local-host ip addresses must still be provided in session
establishment messages due to existing application idiosyncrasies. This
mode of communication uses shared-memory fifos (cut-through sessions)
exclusively.
If applications request no namespace, they are assigned to the default
one, which at its turn uses the default fib. Applications can request
access to both local and global scopes for a namespace. If no scope is
specified, session layer defaults to the global one.
When a sw_if_index is provided for a namespace, zero-ip (INADDR_ANY)
binds are converted to binds to the requested interface.

A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.

- Teach vpp_api_test to send/receive API messages over sockets
- Add memfd-based shared memory
- Add api messages to create memfd-based shared memory segments
- vpp_api_test supports both socket and shared memory segment connections
- vpp_api_test pivot from socket to shared memory API messaging
- add socket client support to libvlibclient.so
- dead client reaper sends ping messages, container-friendly
- dead client reaper falls back to kill (<pid>, 0) live checking
if e.g. a python app goes silent for tens of seconds
- handle ping messages in python client support code
- teach show api ring about pairwise shared-memory segments
- fix ip probing of already resolved destinations (VPP-998)
We'll need this work to implement proper host-stack client isolation

An external (to VPP) process can register (over the VPP binary API) to
receive control plane packets over a UNIX domain socket. The packets are
prepended with a packet descriptor containing meta-data (if_index of
interface, etc).
Currently only UDP is supported.
The socket supports sending of packets/frames as well.
The sent packet is prepended with a descriptor, telling VPP to
route the packet (via ip4-lookup, ip6-lookup) or as an pre-formed
Ethernet frame that is sent directly to interface-output.
The intended use case for this is for an external DHCP client or
a RIP implementation.
New configuration option:
punt { socket <socket path> }
To register use the punt_socket API message.
TODO:
- Add support for pre-routing. I.e send L3 packet to given
TX interface, but do ARP/ND (ip[46]-rewrite)
- Add test scripts
- Support for abstract names (starting with \0)
- Add rate limiting (COP)
- Support for other protocols, e.g. IPv6 ND
