NetworkPolicy not working in EKS

[axkng]

I have a EKS-cluster in which I deployed calico for networkpolicy enforcement.
To test if everything works, I created a test namespace with a pod in it and created a networkpolicy, that would deny all ingress-traffic.
If I now try to reach this pod from another pod in another namespace, it just works.

Expected Behavior

I expected the pod to not be reachable.

Current Behavior

The pod is reachable.

Possible Solution

Steps to Reproduce (for bugs)

1. Create a EKS-cluster (v.1.21.9), with bottlerocket-os on t4g-instances with the cluster using ipv6 and vpc-cni.
2. Now install calico to the cluster, following the guide of AWS
3. Deploy a example workload with a policy denying all ingress.
4. Try to reach the example workload from another pod, possibly in another namespace.

Context

I want to isolate workloads in different namespace from eachother, which is not possible now.

Your Environment

• Calico version 3.22.1
• Orchestrator version (e.g. kubernetes, mesos, rkt): Kubernetes 1.21.9
• Operating System and version: Bottlerocket OS 1.6.2 (on ARM)
• Link to your project (optional):

In my opinion, it would be useful to share at least the network policy manifest.

[axkng]

That is correct.
I used this manifest to setup a quick test environment:

---
apiVersion: v1
kind: Namespace
metadata:
  name: test
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  namespace: test
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 1
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx
        ports:
        - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: nginx
  namespace: test
spec:
  selector:
    app: nginx
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80
---
kind: NetworkPolicy
apiVersion: networking.k8s.io/v1
metadata:
  name: default-ingress-deny
  namespace: test
spec:
  podSelector:
    matchLabels:
      app: nginx
  ingress: []

It does not matter if I try to connect to the pod directly or via the service. I am always able to connect.

[vladyslav-mahilevskyi]

Your Network Policy seems to be wrong.
Please try this one.

---
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: default-deny-ingress
  namespace: test
spec:
  podSelector:
    matchLabels:
      app: nginx
  policyTypes:
  - Ingress

Hi @vladyslav-mahilevskyi ,
I updated the policy, but I am still able to connect.

At which logs would I look to see if Calico even evaluates the config?
To me it seems like the policy is just ignored.

[caseydavenport]

@Furragen I would look at iptables on the host running the nginx pod to see if there are any rules programmed starting with cali-tw.

You can also check the calico/node pod on that host for warning / error level logs.

[axkng]

Hi @caseydavenport ,
thanks for the suggestion.
I looked at the node a saw a lot of rules starting with cali-tw.

The logs of the calico-pod on the node contain no errors.
But, I spotted this for example:

2022-03-24 06:54:37.956 [INFO][52] felix/int_dataplane.go 1520: Received *proto.WorkloadEndpointUpdate update from calculation graph msg=id:<orchestrator_id:"k8s" workload_id:"test/nginx-deployment-7cdf68cd58-vkz5z" endpoint_id:"eth0" > endpoint:<state:"active" name:"enifed5b5a59d8" profile_ids:"kns.test" profile_ids:"ksa.test.default" ipv6_nets:"xxxxxxx/128" tiers:<name:"default" ingress_policies:"test/knp.default.default-ingress-egress-deny"

This looks to me like a hint that calico at least knows about the policy.

Calico version 3.22.1
Orchestrator version (e.g. kubernetes, mesos, rkt): Kubernetes 1.21.9
Operating System and version: Bottlerocket OS 1.6.2 (on ARM)

I was reminded of this issue but if you're not seeing the ipset error logs then that OS is probably using a compatible ipset version.

Are you able to share the relevant cali-tw iptables rules? (With any redactions as needed.)

[axkng]

Hi,
sorry for coming back to this issue so late.

Here are the (probably relevant) iptables-rules from the node on which the pod runs that should not be reachable:

^ These look like the relevant chains to me. You can see that the policy exists and has the correct rules within it here:

Chain cali-pi-_DYtwCKMZFWyxK2RhACP (1 references)
target     prot opt source               destination
           all  --  anywhere             anywhere             /* cali:j53w2cHoSsmy_etr */ /* Policy test/knp.default.default-ingress-egress-deny ingress */

One thing that is missing in this output is a measure of which rules are being hit - I usually prefer to look at iptables-save -c since it includes packet counters.

[axkng]

Hi,
so the only lines I found in the output of iptables-save -c with the relevant chains in them are these:

:cali-pi-_DYtwCKMZFWyxK2RhACP - [0:0]
[0:0] -A cali-pi-_DYtwCKMZFWyxK2RhACP -m comment --comment "cali:j53w2cHoSsmy_etr" -m comment --comment "Policy test/knp.default.default-ingress-egress-deny ingress"
[0:0] -A cali-tw-enibb9994cc117 -m comment --comment "cali:rYjWtMya5MVONeA_" -m mark --mark 0x0/0x20000 -j cali-pi-_DYtwCKMZFWyxK2RhACP

Is that helpful for you?

[caseydavenport]

It seems to suggest that no packets are reaching the default-deny rule, so are probably being accepted / handled earlier in iptables processing.

[axkng]

Okay, thats what I was suspecting. Why would that be?

Also, I stumbled upon logs like this, while researching something else:

timeout or abort while handling: method=GET URI="/apis/projectcalico.org/v3/networkpolicies?allowWatchBookmarks=true&resourceVersion=14995051&timeout=32s&watch=true"

This is from the apiserver.
Is that relevant?

[caseydavenport]

probably not - that error is probably just the API server's normal timeout for watches, which triggers Calico to restart the watch. Unless you're seeing error logs in the Calico logs that seem correlated, that's probably a red herring.

I think the next step here is just to collect all of the relevant diags at once so I can try to comb through for what might be wrong. Right now I'm missing a few things:

• Full iptables-save -c output for packet counts (after sending some traffic that you expect to be blocked).
• Full calico/node logs from the node hosting that pod
• kubectl get networkpolicy -A -o yaml

I'll also try to find some time to repro this myself, but our automated EKS tests do verify this setup so I expect this might be something specific to your environment.

[axkng]

Hi,
so I collected the data and create a few pastebins.

Looks like for whatever reason, the Calico to / from workload chains are being skipped entirely. These rules should be matched by any traffic going through any eni* interfaces. Could you double check that your hosts:

• Have pod interfaces prefixed with "eni"
• That your pods don't have multiple interfaces (perhaps with different names)

[axkng]

So,
I checked the nodes and they have multiple interfaces prefixed with "eni" as I expected.
The pods however have multiple interfaces too.
I did not check all pods, but the ones I checked had interfaces named like this:
"eth0@if107" and "v4if0@if108".

So I guess the pods having more than one interface is a problem?

[caseydavenport]

Potentially - what does your CNI config look like? Are you using multus or something similar to attach pods to multiple networks?

If the pod is sending traffic down an interface that enters the host on a veth (or other interface type) that Calico doesn't know about, it won't be able to enforce policy.

[axkng]

We use vpc-cni, which is installed as a EKS-addon (v1.10.3-eksbuild.1). The config is just the defaults.

Calico is deployed via helm (v3.23.1).
The value that was set there is:

installation:
  kubernetesProvider: EKS

Everything else is just the defaults.

[axkng]

Hi,
can I do anything else to maybe get to the root of this problem?
Shall I provide you with configs or something?

[lwr20]

So I guess the pods having more than one interface is a problem?
Yes it is. It suggests that you have multiple CNI plugins installed somehow.

aws-vpc-cni creates pod interfaces starting with eni. Calico creates them starting with cali. Not sure which plugin creates them like eth0@if107 or v4if0@if108.

Can we see your CNI config file please? i.e. the file on your hosts in /etc/cni/net.d/. Or multiple files if present.

I think we need to fix up your CNI config and disable the rogue plugin.

[lwr20]

Might be unrelated, but I've seen reports recently where containerd and CRIO have started shipping with their own CNI plugin (which doesn't work in kubernetes).

[axkng]

I just wanted to provide you with the configs you asked, but when I connected to one the nodes there was no /etc/cni/net.d.
I just found a snapshot-directory from containerd, projecting this directory into a pod.
So I guessed this would be mounted inside a aws-vpc-cni-pod.
And sure enough, inside those pods I can find a 10-aws.conflist in the mounted directory:

{
  "cniVersion": "0.4.0",
  "name": "aws-cni",
  "disableCheck": true,
  "plugins": [
    {
      "name": "aws-cni",
      "type": "aws-cni",
      "vethPrefix": "eni",
      "mtu": "9001",
      "pluginLogFile": "/var/log/aws-routed-eni/plugin.log",
      "pluginLogLevel": "DEBUG"
    },
    {
      "name": "egress-v4-cni",
      "type": "egress-v4-cni",
      "mtu": 9001,
      "enabled": "true",
      "nodeIP": "x.x.x.x",
      "ipam": {
         "type": "host-local",
         "ranges": [[{"subnet": "x.x.x.x/xx"}]],
         "routes": [{"dst": "0.0.0.0/0"}],
         "dataDir": "/run/cni/v6pd/egress-v4-ipam"
      },
      "pluginLogFile": "/var/log/aws-routed-eni/egress-v4-plugin.log",
      "pluginLogLevel": "DEBUG"
    },
    {
      "type": "portmap",
      "capabilities": {"portMappings": true},
      "snat": true
    }
  ]
}

I wonder how any rogue cni might have gotten into the cluster though, as I only ever installed vpc-cni and calico, nothing else.

Also, thanks for your feedback :)

[lwr20]

That file looks pretty close to the template in the vpc-cni repo: https://github.com/aws/amazon-vpc-cni-k8s/blob/master/misc/10-aws.conflist

but when I connected to one the nodes there was no /etc/cni/net.d.
I just found a snapshot-directory from containerd, projecting this directory into a pod.

So we need to figure out where on your nodes the CNI config is - /etc/cni/net.d is the default, clearly you're not using the default. The CNI plugin is run on the host directly (either by kubelet or by your container runtime), not inside a container or pod, so we need to find where your host is looking for CNI config and what its running. Look at kubelet and CNI configs and see if you can find that info.

[axkng]

So, I made a mistake when I first looked for the config.
In Bottlerocket OS, when you use the admin-container that does not mean you see the actual contents of the rootfs of the host.
But you can do that if you use sheltie.
And it turns out that /etc/cni/net.d/is present and contains the config I posted earlier.

[Linutux42]

Hello,

I just found this issue while troubleshooting a very similar behavior on our side and thought sharing might help.
We are running EKS 1.21 with vpc-cni and Calico. We just migrated this morning from the old calico yaml files to calico helm chart 3.23.1 without major issues. (just a few hiccups with annotation and node selector being present and cpu limits making the readiness probe to always fail on the calico-node pods, to which we just removed the limits for now and it is fine now)

And when we tried to play with a basic namespace deny-all policy in order to validate that calico was still working, we had troubles :)
So we created a basic http deployment+service+ingress answering 200/OK. Working without issues.
Then we added a network policy to deny all traffic in the namespace which would block the traffic from nginx to the pod. But then nothing happened. We looked at the calico-node's log and we could see the update of the policy being mentionned. And finally after a good 2 minutes the traffic was blocked.
So then we tried to remove the deny-all policy from the namespace and now the traffic is still stuck between nginx and the pod.

I checked /etc/cni/net.d/ and there is one file called 10-aws.conflist with the following content:

{
  "cniVersion": "0.3.1",
  "name": "aws-cni",
  "plugins": [
    {
      "name": "aws-cni",
      "type": "aws-cni",
      "vethPrefix": "eni",
      "mtu": "9001",
      "pluginLogFile": "/var/log/aws-routed-eni/plugin.log",
      "pluginLogLevel": "DEBUG"
    },
    {
      "type": "portmap",
      "capabilities": {"portMappings": true},
      "snat": true
    }
  ]
}

I checked the pod interfaces as well and there is only 1 interface attached to the pod which ends with an interface called eni<something> which looks like what you said it should look like.

I also checked the iptables-save -c and found the rule but the packet counter are at 0 even though nginx is still unable to talk to the pod.

If there is tests you want me to perform, let me know :)
Cheers

[axkng]

Any news on this?
Is more info necessary on something?

[axkng]

Hey,
is somebody still looking into this?

@Linutux42 did you maybe find a solution or workaround?

[christian-vdz]

Hello, I'm having the same issue using EKS version 1.22 with amazon optimized AMI and VPC CNI + Calico plugin.
I'd love to know if anyone has found out how to fix this.

[Linutux42]

@Linutux42 did you maybe find a solution or workaround?

@Furragen I haven't had time to investigate more for now, sorry :/

[pgarrett-twc]

Hi, same problem here. I'm following the stars policy demo instructions, and when I get to adding the default-deny policy, it has no effect.

My environment is:

• EKS
• Kubernetes 1.22
• IPv6
• vpc-cni 1.11.2
• calico installed via tigera-operator helm chart 3.23.3

[Linutux42]

Hello,

I upgraded my EKS clusters to 1.22 a few days ago and I found a few minutes to test again the migration to the official tigera-operator helm chart v3.24.1.
I tried to spawn a pod in a namespace with a deny all network policy and i couldn't reach anything within that pod. The second I removed the netpol everything was working as planned.
So something fixed the issue between k8s 1.21 and 1.22 and between tigera-operator v3.21.4 and v3.24.1.
I can't tell you what fixed it, or which of the 2 fixed it and unfortunately I don't have time to investigate further for the moment.

@Furragen Try with v3.24.1 and see if it works ¯\(ツ)/¯

[rusanki]

any update on this ? I am stuck with the same issue and not able to enforce NetworkPolicy. It works sometimes but not all the times when I reapply.

[groovybears]

Greetings,

We are having the same issue but only with one cluster out of two:

1. both EKS clusters are 1.21
2. identical in every configuration/services deployed
3. same tigera operator version/helm chart

[tomastigera]

Closing as stale, pls reopen if you are still seeing these issues.

[aadamovich]

EKS 1.27, VPC-CNI, Calico 3.26.1. Behavior seems to be quite random. Some policies work as expected. Some services just timeout without any policies and others work fine.

[gss2002]

I am seeing this with EKS 1.24 and VPC-CNI with Calico 3.26.1... Exactly as @aadamovich describes some times things are blocked sometimes they are not.. results are very un-predicitable.

[vaskozl]

Official documentation now states:

You can't use IPv6 with the Calico network policy engine add-on.

@tomastigera can you please re-open the issue, at the present this is the only one I can find tracking IPv6 netpols with the EKS provider and it definitely doesn't work, even with ipv6Support=true in the felixconfiguration.

[gss2002]

In my case I am not using IPv6 followed Calico/AWS EKS doc to the T and nothing works... The two things that I wonder if its affecting it is use of secondary subnet 100.x.x.x subnets with PODS

    - name: ENABLE_IPv6
      value: "false"
    - name: ENABLE_POD_ENI
      value: "true"
    - name: POD_SECURITY_GROUP_ENFORCING_MODE
      value: standard
    - name: ANNOTATE_POD_IP
      value: "true"
    - name: AWS_VPC_K8S_CNI_CUSTOM_NETWORK_CFG
      value: "true"

I also see the following errors in calico-node logs:

[gss2002]

Does anyone know if this is the proper doc to follow to enable K8S Policies using Calico with EKS as AWS doesn't seem to reference purging aws-node daemonset.

https://docs.aws.amazon.com/eks/latest/userguide/calico.html - doesn't reference deleting "aws-node" daemonset

Where as the Calico Doc says purge "aws-node" - https://docs.tigera.io/calico/latest/getting-started/kubernetes/managed-public-cloud/eks#install-eks-with-amazon-vpc-networking

Once aws-node is purged and the rest of the instructions are followed here NetworkPolicies work...

Since this cluster will use Calico for networking, you must delete the aws-node daemon set to disable AWS VPC networking for pods.

kubectl delete daemonset -n kube-system aws-node

https://docs.tigera.io/calico/latest/getting-started/kubernetes/managed-public-cloud/eks#install-eks-with-amazon-vpc-networking

[lwr20]

I think there might be some confusion.
https://docs.tigera.io/calico/latest/getting-started/kubernetes/managed-public-cloud/eks
talks about 2 completely different ways to use Calico with an EKS cluster.

One is combining Calico with AWS-VPC-CNI (which is installed by aws-node).
The other is removing AWS-VPC-CNI and replacing it with Calico CNI.

Calico with VPC-CNI installation instructions are here: https://docs.aws.amazon.com/eks/latest/userguide/calico.html
If you're using this, you MUST NOT delete the aws-node daemonset.

Calico with Calico-cni installation instructions are here: https://docs.tigera.io/calico/latest/getting-started/kubernetes/managed-public-cloud/eks#install-eks-with-calico-networking

Both methods should "just work". Both methods have pros and cons (see the doc).

Hi

We are facing similar issues. sometimes connection was successful and sometimes it failed.. any response much appreciated
