2017-10-15Revert "Enforce FIB table creation before use"Florin Coras2-3/+37
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.

2017-10-13VPP-1027: DNS name resolverDave Barach1-0/+3
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 Change-Id: I48c373d5c05d7108ccd814d4055caf8c75ca10b7 Signed-off-by: Dave Barach <dave@barachs.net>
2017-10-10session: add support for application namespacingFlorin Coras4-0/+162
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.

2017-10-05Distributed Virtual Router SupportNeale Ranns2-0/+6
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.

2017-09-05PUNT socket: External control plane processes connected via UNIX domain sockets.Ole Troan3-11/+555
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 Change-Id: I4a0afc8020deebb3d9d74686dde694ee5bcb8d0f Signed-off-by: Ole Troan <ot@cisco.com>
