2018-01-23VPPAPIGEN: vppapigen replacement in Python PLY.Ole Troan2-2/+2
This is a version of the VPP API generator in Python PLY. It supports the existing language, and has a plugin architecture for generators. Currently C and JSON are supported. Changes: - vl_api_version to option version = "major.minor.patch" - enum support - Added error checking and reporting - import support (removed the C pre-processor) - services (tying request/reply together) Version: option version = "1.0.0"; Enum: enum colours { RED, BLUE = 50, }; define foo { vl_api_colours_t colours; }; Services: service { rpc foo returns foo_reply; rpc foo_dump returns stream foo_details; rpc want_stats returns want_stats_reply events ip4_counters, ip6_counters; }; Future planned features: - unions - bool, text - array support (including length) - proto3 output plugin - Refactor C/C++ generator as a plugin - Refactor Java generator as a plugin Change-Id: Ifa289966c790e1b1a8e2938a91e69331e3a58bdf Signed-off-by: Ole Troan <ot@cisco.com>

2018-01-11api: remove transport specific code from handlersFlorin Coras2-67/+64
This does not update api client code. In other words, if the client assumes the transport is shmem based, this patch does not change that. Furthermore, code that checks queue size, for tail dropping, is not updated.

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.
