2024-05-07api: add to_net parameter to endian messagesOle Troan1-2/+3
The VPP API auto-generated endian conversion functions are intended to be symmetrical. They are used both by the API client and the API server. Called on send to convert from host endian to network endian and on receive to convert back. For variable length arrays, we have to iterate over the array and call a more specific handler for the array type. Unfortunately the length of the array is part of the api definition, and if it's endian swapped prior to the for loop, unexpected behaviour will ensue. There was an earlier fix, for some specific messages, but unfortunately that only fixed the problem from the VPP (server) side. This adds a new parameters to the endian handler, so the boundary argument to the loop can be treated differently depending on if this message is to the network or from the network.

2022-05-12pnat: add support to wildcard IP Protocol field if not specifiedFahad Naeem4-4/+39
- add pnat_binding_add_v2 which explicitly requires match mask to set to PNAT_PROTO if we want to match on IP Protocol - fix pnat_binding_add backward compatibility i.e. no need to set match mast to PNAT_PROTO Type: improvement Signed-off-by: Fahad Naeem <fahadnaeemkhan@gmail.com> Change-Id: I5a23244be55b7d4c10552c555881527a4b2f325f
2022-05-10tests: replace pycodestyle with blackKlement Sekera1-14/+16
Drop pycodestyle for code style checking in favor of black. Black is much faster, stable PEP8 compliant code style checker offering also automatic formatting. It aims to be very stable and produce smallest diffs. It's used by many small and big projects. Running checkstyle with black takes a few seconds with a terse output. Thus, test-checkstyle-diff is no longer necessary. Expand scope of checkstyle to all python files in the repo, replacing test-checkstyle with checkstyle-python. Also, fixstyle-python is now available for automatic style formatting. Note: python virtualenv has been consolidated in test/Makefile, test/requirements*.txt which will eventually be moved to a central location. This is required to simply the automated generation of docker executor images in the CI.

2021-02-05nat: 1:1 policy NATOle Troan12-0/+2178
A NAT sub-plugin doing statically configured match/rewrite on IP4 input or output. It's stateless (no connection tracking). Currently it supports rewriting of SA, DA and TCP/UDP ports. It should be simple to add new rewrites if required. API: pnat_binding_add, pnat_binding_del, pnat_bindings_get, pnat_interfaces_get CLI: set pnat translation interface <name> match <5-tuple> rewrite <5-tuple> {in|out} [del] show pnat translations show pnat interfaces Trying a new C based unit testing scheme. Where the graph node is tested in isolation. See pnat/pnat_test.c. Also added new cmake targets to generate coverage directly.
