Release Notes

containernetworking/cni (github.com/containernetworking/cni)

v1.2.1: CNI Spec v1.1 / libcni v1.2.1

Compare Source

This is a minor release that fixes some small bugs:

Improvements

• (#​1098). SPEC: add warning about preserving shared resources for GC
• (#​1090). Spec, libcni: add disableGC flag This allows administrators to disable garbage collection in exceptional circumstances, such as multiple runtimes sharing a network configuration.

Bug fixes:

• (#​1097). Fix faulty json.Marshal behavior for embeds types.NetConf Fix #​1096
• (#​1095). libcni: always delete the cache on conflist for CNI DEL This aligns the call with DelNetwork, and allows CRIO tests to bump

v1.2.0: CNI spec v1.1 / libcni v1.2.0

Compare Source

This is libcni v1.2.0, which releases the new CNI spec version v1.1.0.

Major changes:

GC verb

The GC verb allows runtimes to specify the set of known-good attachments, allowing plugins to clean up stale and leaked resources such as IPAM reservations. Libcni will also synthesize a CNI DEL for any stale cached attachments, so all users will have a form of GC, even if their plugins do not support CNI v1.1

STATUS verb

The STATUS verb allows a plugin to report its readiness to accept ADD requests. Runtimes such as containerd and cri-o will no longer have to rely merely on the presence of a CNI configuration file to determine network readiness.

Version negotiation

CNI configurations may now contain multiple versions, so that an administrator can opportunistically update the protocol version without breaking older runtimes:

{
  "cniVersion": "1.0.0",
  "cniVersions": ["1.0.0", "1.1.0"]
}

New fields

A number of new fields have been added to the result type:

• (#​1060). Add MTU to CNI result
• (#​1068). Add Scope property for routes Fixes: #​598
• (#​1069). Add SocketPath/PciID to Interface struct This is to resolve: #​1050
• (#​1062). Add table ID property for routes Fixes #​1061
• (#​1041). Add route attributes - MTU, AdvMSS, Priority

Other improvements

• (#​911). libcni: add specific type for CHECK not supported
• (#​1072). tolerate invalid cni caches for deletion
• (#​1054). Add Version() to CNI interface
