2021-12-03fib: Fix the display (or lack of) for fib node types in dependent children listsNeale Ranns1-1/+2
Type: fix When registering a new FIB node type, no name was required on the API, and so no name was printed. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I8a99cf29c194637a550061b0a5e9782ffe8b31dd
2021-11-19fib: Don't use [midchain] adjacencies to change an interface's feature arcNeale Ranns2-3/+6
Type: fix Using the adjacency to modify the interface's feature arc doesn't work, since there are potentially more than one adj per-interface. Instead have the interface, when it is created, register what the end node of the feature arc is. This end node is then also used as the interface's tx node (i.e. it is used as the adjacency's next-node). rename adj-midhcain-tx as 'tunnel-output', that's a bit more intuitive. There's also a fix in config string handling to: 1- prevent false sharing of strings when the end node of the arc is different. 2- call registered listeners when the end node is changed For IPSec the consequences are that one cannot provide per-adjacency behaviour using different end-nodes - this was previously done for the no-SA and an SA with no protection. These cases are no handled in the esp-encrypt node. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: If3a83d03a3000f28820d9a9cb4101d244803d084

2021-02-08tunnel: support copying TTL and flow label from inner to outerNeale Ranns1-2/+3
Type: feature The added functionality is to support copying TTL and flow label from inner to outer. The .api was extened to support expressing this and also adding a common tunnel endpoint type. i find it best to make API changes in one patch so there are less versions of the API.

2020-05-04fib: midchain adjacency optimisationsNeale Ranns1-11/+27
Type: improvement - inline some common encap fixup functions into the midchain rewrite node so we don't incur the cost of the virtual function call - change the copy 'guess' from ethernet_header (which will never happen) to an ip4 header - add adj-midchain-tx to multiarch sources - don't run adj-midchain-tx as a feature, instead put this node as the adj's next and at the end of the feature arc. - cache the feature arc config index (to save the cache miss going to fetch it) - don't check if features are enabled when taking the arc (since we know they are) the last two changes will also benefit normal adjacencies taking the arc (i.e. for NAT, ACLs, etc) for IPSec: - don't run esp_encrypt as a feature, instead when required insert this node into the adj's next and into the end of the feature arc. this implies that encrypt is always 'the last feature' run, which is symmetric with decrypt always being the first. - esp_encrpyt for tunnels has adj-midchain-tx as next node Change-Id: Ida0af56a704302cf2d7797ded5f118a781e8acb7 Signed-off-by: Neale Ranns <nranns@cisco.com>

Split generation of API message enum and the typedefs into separate files, so that the type file can be included from elsewhere. Generate a C file for VPP that contains the API registration, this was previously done via X macros by the C pre- processor. This allows deleting lots of skeleton/copy paste code for each feature. plugins/flowprobe plugins/map examples/sample-plugin vnet/ipip used as Guinea pigs. Generate a C Test file for VAT, that does the same for VAT plugins. Also add support for a per-message CLI option, that is currently limited to VAT help text. option vat_help = "<help text>"; Type: refactor Change-Id: I245e3104bb76f7e1fb69a59ab20cc7c8dfcdd460 Signed-off-by: Ole Troan <ot@cisco.com>
2019-07-19fib: FIB Entry trackingNeale Ranns1-10/+7
Instead of all clients directly RR sourcing the entry they are tracking, use a deidcated 'tracker' object. This tracker object is a entry delegate and a child of the entry. The clients are then children of the tracker. The benefit of this aproach is that each time a new client tracks the entry it doesn't RR source it. When an entry is sourced all its children are updated. Thus, new clients tracking an entry is O(n^2). With the tracker as indirection, the entry is sourced only once.
