Mohsin Kazmi 6809538e64 vlib: refactor checksum offload support
Type: refactor

This patch refactors the offload flags in vlib_buffer_t.
There are two main reasons behind this refactoring.
First, offload flags are insufficient to represent outer
and inner headers offloads. Second, room for these flags
in first cacheline of vlib_buffer_t is also limited.

This patch introduces a generic offload flag in first
cacheline. And detailed offload flags in 2nd cacheline
of the structure for performance optimization.

Wireguard vpp-plugin

Overview

This plugin is an implementation of wireguard protocol for VPP. It allows one to create secure VPN tunnels. This implementation is based on wireguard-openbsd.

Crypto

The crypto protocols:

OpenSSL:

  • curve25519
  • chachapoly1305

Plugin usage example

Create wireguard interface

> vpp# wireguard create listen-port <port> private-key <priv_key> src <src_ip4> [generate-key]
> *wg_interface*
> vpp# set int state <wg_interface> up
> vpp# set int ip address <wg_interface> <wg_ip4>

Add a peer configuration:

> vpp# wireguard peer add <wg_interface> public-key <pub_key_other> endpoint <ip4_dst> allowed-ip <prefix> dst-port <port_dst> persistent-keepalive [keepalive_interval]
> vpp# *peer_idx*

Show config

> vpp# show wireguard interface
> vpp# show wireguard peer

Remove peer

> vpp# wireguard peer remove <peer_idx>

Delete interface

> vpp# wireguard delete <wg_interface>

Main next steps for improving this implementation

  1. Use all benefits of VPP-engine.
  2. Add IPv6 support (currently only supports IPv4)
  3. Add DoS protection as in original protocol (using cookie)
