2018-01-23VPPAPIGEN: vppapigen replacement in Python PLY.Ole Troan1-1/+1
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>

2017-10-05Distributed Virtual Router SupportNeale Ranns1-7/+1
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.

2017-05-23ARP/ND entries for the same address on different interfaces (VPP-848)Neale Ranns2-99/+20
there are, intentionally, no validation checks in the ARP/ND code to prevent an ARP/ND entry from being installed for an address that is not local to the interface's sub-net. This is ok, since the adjacency/FIB code is designed to handle this case using the 'refinement' criteria - i.e. only installing a FIB entry for the address if the address 'refines' (i.e. is more specific than) the interface's sub-net. However, the refinement criteria currently operates on the FIB entry's prefix (which is a /32, so on the address) and not on the next-hop in the path. So, enter multiple ARP entries for the same address on different links, and this refinement criteria uses only the last added path, and so will remove the FIB entry should the ARP entries be added in the 'wrong' order. This fix updates the refinement criteria to work on each path of the FIB entry. The entry is installed if one of the paths refines the covers and only paths refining the cover contribute forwarding. Per-path refinement checks are stored in path-extensions. The patch is rather large as path-extension, which were previously used only for out-going MPLS labels, have been generalized.

1 - interface-DPO Used in the Data-plane to change a packet's input interface 2 - MPLS multicast FIB entry Same as a unicast entry but it links to a replicate not a load-balance DPO 3 - Multicast MPLS tunnel Update MPLS tunnels to use a FIB path-list to describe the endpoint[s]. Use the path-list to generate the forwarding chain (DPOs) to link to . 4 - Resolve a path via a local label (of an mLDP LSP) For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP. 5 - MPLS disposition path sets RPF-ID For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet. 6 - RPF check with per-entry RPF-ID An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.

This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent.

Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
