2017-11-10add classify session action set-sr-policy-indexGabriel Ganne1-0/+2
This allows to use the classifier to steer source routing packets instead of using the "sr steer" command. This way we can steer on anything instead of only the dst ip address. test: * add add_node_next function to the VppPapiProvider class. * add simple test scenario using the classifier to steer packets with dest ip addr == a7::/8 to the source routing insert node. * use new interface indexes (3,4) instead of (0,1) to prevent a cleanup conflict with the other tests which attach a specific fib to the interface. The test creates interfaces sepsrated from the other tests to prevent a conflict in the cleaning of the ip6 fib index 1 which causes vpp not to be able to find a default route on this table.

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. Change-Id: I23bd345523b20789a1de1b02022ea1148ca50797 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-11-01session: add support for proxying appsFlorin Coras1-1/+3
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. Change-Id: I791f8c1cc083350f02e26a2ac3bdbbfbfa19ece3 Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-10-28session: rules tablesFlorin Coras2-0/+118
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.

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.
