Support tunnel routing in Multi-Pool IPAM mode #38483

pippolo84 · 2025-03-25T11:06:33Z

Rework of #38015 after the introduction of clusterID aware ipcache in #38379

The main difference with #38015 is commit fa35fa0 where we take advantage of the ClusterPrefix parameter type in ipcache API to enrich the node prefixes (namely, the CiliumInternalIP, the Ingress and health IPs and the v4/v6 allocation CIDRs) with the result of a customizable PrefixClusterMutatorFn. This guarantees feature parity with the tunnel map previously used for node allocation CIDRs.

Description of the previous version of the PR (#38015) below:

This PR introduces support for tunnel routing with the Multi-Pool IPAM mode. This is achieved by removing the reliance on the tunnel map as a fallback mechanism and instead use Pod CIDR entries in IPCache that act as this fallback. The pod CIDR entries contain the node's tunnel endpoint and encryption key and have the reserved:world identity (i.e. the same identity as the existing catch-all fallback, which would have been hit before this PR).

The bulk of the work in this PR was done by @pippolo84. This PR is a replacement for his PR #37146 with a few notable changes:

The first commit has been reworked to add unit tests and fix up some issues in the previous version (c.f. Use ipcache for tunneling #37146 (comment)).
A commit has been added adding some unit tests to the IPCache package emulating some of the expected corner cases.
Commit node: Remove insertions and deletions to tunnel map has been dropped. In other words, even though the tunnel map is no longer used in the main branch, we still populate it. This addresses concerns with regards to downgrades.
The Conformance Multi-Pool workflow has been extended to also test in tunnel mode.

This change will eventually allow us to remove the tunnel map completely (ref #20170).

Add support for tunnel routing in multi-pool IPAM mode

Thanks! A couple of comments inline, besides that looks great to me.

docs good

besides Marco's review about waiting for image step, looks good for github-sec and ci-structure

One more comment inline (above), looks good to me otherwise.

Multi-Pool IPAM is now compatible with tunneling, update the IPAM modes feature compatibility table accordingly. Related: cilium#38483 Signed-off-by: Fabio Falzoi <fabio.falzoi@isovalent.com>

Thanks to the VinE support added in #37723, when in tunnel mode we encrypt the traffic after the encapsulation, at the native egress device. Therefore, the only entries (policies and states) needed for the XFRM framework to encrypt the traffic are the ones related to the remote nodes, not the ones related to the remote pod CIDRs. As a consequence, the multi-pool IPAM mode is now supported when IPSec is enabled in tunnel mode, therefore, update the related startup check to stop the agent only when multi-pool IPAM and IPSec transparent encryption are enabled in native routing mode.

Multi-Pool IPAM is now compatible with tunneling too and it does not require native routing mode anymore. Therefore, in order to simplify the Multi-Pool IPAM tutorial in the docs, remove the options related to native routing. Related: #38483 Signed-off-by: Fabio Falzoi <fabio.falzoi@isovalent.com>

Therefore, in order to simplify the Multi-Pool IPAM tutorial in the docs, remove the options related to native routing. Related: cilium#38483 Signed-off-by: Fabio Falzoi <fabio.falzoi@isovalent.com>
