v1.3.0

What's Changed

• RFC - Support safe subdirectory-based plugin conf loading by @bleggett in #1052

This adds a new config flag loadPluginsFromFolder - if present, for a given named network bar, plugin configuration objects will be loaded from <path-to-bar-network-config-file>/bar/xxx.conf. This may be useful for vendors providing chained plugins: you can add your plugin to a chain without needing to edit the file in-place.

New Contributors

• @bleggett made their first contribution in #1052

Full Changelog: v1.2.3...v1.3.0

libcni v1.2.3

This is a minor release to correct a divergence between the specification and libcni. In this case, the specification was updated, as it concerns a new feature, GC, that is not yet deployed.

What's Changed

• SPEC, libcni: harmonize GC valid-attachment key by @squeed in #1103

libcni v1.2.2

What's Changed

• libcni: remove use of Masterminds/semver by @squeed in #1100

Full Changelog: v1.2.1...v1.2.2

CNI Spec v1.1 / libcni v1.2.1

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

CNI spec v1.1 / libcni v1.2.0

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

CNI v1.1.2

This is a minor update to the CNI libraries and tooling. This does not bump the protocol / spec version, which remains at v1.0.0.

What's Changed

• spec: fix format by @drivebyer in #902
• Fix successfully unmarshalled nil raw result by @brandond in #904

New Contributors

• @drivebyer made their first contribution in #902
• @brandond made their first contribution in #904

CNI v1.1.1

This is a minor update to the CNI libraries and tooling. This does not bump the protocol / spec version, which remains at v1.0.0.

Changes include:

• cnitool: address golint error by @fujitatomoya in #894
• invoke: if Result CNIVersion is empty use netconf CNIVersion by @dcbw in #896

CNI v1.1.0

This is a minor update to the CNI libraries and tooling. This does not bump the protocol / spec version, which remains at v1.0.0.

Changes include:

• libcni: handle empty version when parsing version (#893). Without this, Delete failed for empty-version configs, which was a regression from v0.8.0.
• Fix incorrect pointer inputs to json.Unmarshal (#880).
• [exec-plugins]: support plugin lists (#865).
• skel: remove superfluous err nil check in (*dispatcher).pluginMain (#864).
• skel: print out CNI versions supported in help text (#860).

🎉 CNI v1.0.1 🎉

Hot off the presses, it's CNI v1.0!

CNI v1.0 doesn't change much about how CNI works, but it declares API stability.

This release includes

• a rewritten spec (for clarity)
• libcni improvements
• way more tests.

CNI v0.8.1

libcni v0.8.1

This is a security release that fixes a single bug:

• tighten up plugin-finding logic (#811).

Users of libcni are strongly encouraged to update.
