Alina Sudakov 48aa2f4eef Fix race conditions in DHCP test 
The test named "correctly handles multiple DELs for the same container" in the ipam/dhcp package experiences race conditions when multiple goroutines concurrently access and modify the Args struct (of type CmdArgs).
To address these issues, a copy of the CmdArgs struct is now created in each function to eliminate data races.

Also, the test-linux.sh and test-windows.sh scripts have been updated to include the '-race' flag, enabling race detection during testing. This change helps prevent future race conditions by activating the Go race detector.

Plugins

Some CNI network plugins, maintained by the containernetworking team. For more information, see the CNI website.

Read CONTRIBUTING for build and test instructions.

Plugins supplied:

Main: interface-creating

  • bridge: Creates a bridge, adds the host and the container to it.
  • ipvlan: Adds an ipvlan interface in the container.
  • loopback: Set the state of loopback interface to up.
  • macvlan: Creates a new MAC address, forwards all traffic to that to the container.
  • ptp: Creates a veth pair.
  • vlan: Allocates a vlan device.
  • host-device: Move an already-existing device into a container.
  • dummy: Creates a new Dummy device in the container.

Windows: Windows specific

  • win-bridge: Creates a bridge, adds the host and the container to it.
  • win-overlay: Creates an overlay interface to the container.

IPAM: IP address allocation

  • dhcp: Runs a daemon on the host to make DHCP requests on behalf of the container
  • host-local: Maintains a local database of allocated IPs
  • static: Allocate a single static IPv4/IPv6 address to container. It's useful in debugging purpose.

Meta: other plugins

  • tuning: Tweaks sysctl parameters of an existing interface
  • portmap: An iptables-based portmapping plugin. Maps ports from the host's address space to the container.
  • bandwidth: Allows bandwidth-limiting through use of traffic control tbf (ingress/egress).
  • sbr: A plugin that configures source based routing for an interface (from which it is chained).
  • firewall: A firewall plugin which uses iptables or firewalld to add rules to allow traffic to/from the container.

Sample

The sample plugin provides an example for building your own plugin.
