v1.15 Backports 2024-04-02 #31727

[ upstream commit efff613 ] This commit restructures the OpenShift installation instructions to point to the Red Hat Ecosystem Catalog, so users may find vendor maintained OLM images. The old installation instructions which refer to the deprecated cilium/cilium-olm repository will be moved to the isovalent/olm-for-cilium repository.

[ upstream commit 0c3570c ] Using the node-map-max flag, one can now override the default 16k node map size. This may be needed for large clusters, where the number of distinct node IPs in the cluster exceeds the standard size. Also provides Size() to nodemap.Map interface such that loader can use this to set the NODE_MAP_MAX var while building bpf programs. Signed-off-by: Tom Hadlaw <tom.hadlaw@isovalent.com>

[ upstream commit a596a5a ] This can be used to override the default node-map-max value which sets bpf node map size. In some cases, node map size may need to be overridden for very large clusters. Signed-off-by: Tom Hadlaw <tom.hadlaw@isovalent.com>

[ upstream commit 3d641e1 ] This is the constant default size prior to adding the flag. There's not much reason to lower this value so to avoid edge cases we'll just say that this is the lower bound.

[ upstream commit 4367ffa ] With previous commits adding the ability to adjust nodemap size, this adds a section explaining the implications of the nodemap sizing. Signed-off-by: Tom Hadlaw <tom.hadlaw@isovalent.com> Signed-off-by: Jussi Maki <jussi@isovalent.com>

[ upstream commit a2bf108 ] Let the docs reflect the limitation from GHSA-j89h-qrvr-xc36. Signed-off-by: Julian Wiedmann <jwi@isovalent.com> Signed-off-by: Jussi Maki <jussi@isovalent.com>

[ upstream commit 16f6afe ] Currently, when building the model for shared Ingress, all Ingresses in the cluster are listed and processed. The order of the Ingresses can differ and potentially influence the generated CiliumEnvoyConfig. This can lead to unnecessary reconciles. (Even though the internal translation already handles a stable CiliumEnvoyConfig generation where possible.) In addition to the existing stable translation logic, this commit sorts all shared Ingresses by their namespace and name before processing. This way a consistent translation is more likely to be guaranteed. Signed-off-by: Marco Hofstetter <marco.hofstetter@isovalent.com> Signed-off-by: Jussi Maki <jussi@isovalent.com>

[ upstream commit 54b2ce4 ] To get more coverage about the host firewall, let's add a new job in the e2e test suites to run it alongside WireGuard encryption. Signed-off-by: Quentin Monnet <qmo@qmon.net> Signed-off-by: Jussi Maki <jussi@isovalent.com>

[ upstream commit 1941679 ] DNS Proxy needs to account for protocol when indexing L7 DNS rules that it needs to adhere to, otherwise L7 rules with differing port-protocols can override each other (nondeterministically) and create overly restrictive, and incorrect DNS rules. The problem with accounting for protocol is that Endpoint restoration logic uses DNS rules that index to port-only as JSON saved to disk. Adding an additional protocol index to a map structure changes the JSON structure and breaks restoration logic between Cilium versions. This change makes the map index backwards compatible, since it changes the index from a uint16 to a uint32, both of which marshal the same into a JSON structure. The endpoint restoration logic will succeed between versions, because the older version will be automatically differentiated with a lack of a 1-bit at bit position 24. Version 2 will save a 1 bit at the 24th bit going forward to differentiate when protocol is indexed or not present.

[ upstream commit bc7fbf3 ] DNS Proxy indexes domain selectors by port only. In cases where protocols collide on port the DNS proxy may have a more restrictive selector than it should because it does not merge port protocols for L7 policies (only ports). All callers of the DNS Proxy are updated to add protocol to any DNS Proxy entries, and all tests are updated to test for port-protocol merge errors. Signed-off-by: Nate Sweet <nathanjsweet@pm.me>

[ upstream commit 6baab36 ] DNSRulesV2 accounts for protocol and DNSRules does not. DNSProxy needs to account for both, and endpoint needs to be able to restore from a downgrade. DNSRulesV2 is used by default now, but DNSRules is maintained in case of a downgrade. Signed-off-by: Nate Sweet <nathanjsweet@pm.me>

[ upstream commit abd7c6e ] In cases where a port-protocol is not present in an restored port protocol, look up up the Version 1 version of the PortoProto in case a Version 1 PortProto was restored. Signed-off-by: Nate Sweet <nathanjsweet@pm.me> Signed-off-by: Jussi Maki <jussi@isovalent.com>

[ upstream commit 5185252 ] The Sort methods are updated to take an unused testing.T structure to indicate to all callers that they are only for testing purposes. Signed-off-by: Nate Sweet <nathanjsweet@pm.me> Signed-off-by: Jussi Maki <jussi@isovalent.com>

[ upstream commit e2e97f3 ] While testing cluster scale downs, we noticed that under constant traffic load, we sometimes had drops of type "No node ID found". We confirmed that these are expected when the remote node was just deleted, the delete event received by the local agent, but a local pod is still sending traffic to pods on that node. In that case, the node is removed from the node ID map, but information on pods hosted by that node may still be present. This commit documents it with the other expected reasons for "No node ID found" drops. Signed-off-by: Paul Chaignon <paul.chaignon@gmail.com> Signed-off-by: Jussi Maki <jussi@isovalent.com>

[ upstream commit 43bd8c1 ] This commit fixes a bug in the `cilium-health-ep` controller restart logic where it did not give the cilium-health endpoint enough time to startup before it was re-created. For context, the `cilium-health-ep` performs two tasks: 1. Launch the cilium-health endpoint when the controller is started for the first time. 2. Ping the cilium-health endpoint, and if it does not reply, destroy and re-create it. The controller has a `RunInterval` of 60 seconds and a default `ErrorRetryBaseDuration` of 1 second. This means that after launching the initial cilium-health endpoint, we wait for 60 seconds before we attempt to ping it. If that ping succeeds, we then keep pinging the health endpoint every 60 seconds. However, if a ping fails, the controller deletes the existing endpoint and creates a new one. Because the controller then also returns an error, it is immediately re-run after one second, because in the failure case a controller retries with an interval of `consecutiveErrors * ErrorRetryBaseDuration`. This meant that after a failed ping, we deleted the unreachable endpoint, recreated a new one, and after 1s would immediately try to ping it. Because the newly launched endpoint will is unlikely to be reachable after just one second (it requires a full endpoint regeneration with BPF compilation), the `cilium-health-ep` logic would declare the still starting endpoint as dead and re-create it. This loop would continue endlessly, causing lots of unnecessary CPU churn, until enough consecutive errors have happened for the wait time between launch and the first ping to be long enough for a cilium-health endpoint to be fully regenerated. This commit attempts to fix the logic by not immediately killing a unreachable health endpoint and instead waiting for three minutes to pass before we attempt to try again. Three minutes should hopefully be enough time for the initial endpoint regeneration to succeed. Signed-off-by: Sebastian Wicki <sebastian@isovalent.com>

[ upstream commit 283cb04 ] These configs were recent additions, and missed the introduction of the key-type-* parameters. Add them now. Suggested-by: Paul Chaignon <paul.chaignon@gmail.com> Signed-off-by: Julian Wiedmann <jwi@isovalent.com> Signed-off-by: Jussi Maki <jussi@isovalent.com>

[ upstream commit 820aa07 ] During the key rotations, we compare the number of keys to the expected number to know where we are in the process (started the rotation or finished it). The expected number of keys depends on the configuration so let's print it in the logs to help debug.

[ upstream commit 034aee7 ] Delegated ipam returns ipv6 address to cilium cni even if ipv6 disabled in cilium agent config. In this scenario, ipv6 node addressing is not set and its causing cilium cni to crash if delegated ipam returns ipv6 but disabled in cilium agent.

[ upstream commit 2d32dab ] Like other images used in the Cilium helm chart, use a digest in addition to the tag for the nodeinit image. Signed-off-by: Tobias Klauser <tobias@cilium.io>

[ upstream commit ac804b6 ] Make sure the latest version of the image is used in the helm charts by letting renovatebot update it automatically. Signed-off-by: Tobias Klauser <tobias@cilium.io>

[ upstream commit 129f2e2 ] In commit 6fee46f ("ci/ipsec: Fix downgrade version retrieval") we added a check to make sure that GitHub credentials are removed before pulling the untrusted branch from the Pull Request's author. It appears that this check occasionally fails and causes the whole job to abort. But Cilium's repository _is_ public, and it's unclear why ".private == false" does not evaluate to "false" as we expected in that case. Did the curl request fail? Did the reply miss the expected .private field? We'll probably loosen the check as a workaround, but before that it would be interesting to understand better what's going on. Here we remove the -s flag from curl and print the reply from the GitHub API request, so we can better understand what's going on next time we observe a failure.
