+# Retina
+
+## Overview
+
+Retina is a cloud and vendor agnostic container workload observability platform which helps customers with enterprise grade DevOps, SecOps and compliance use cases. It is designed to cater to cluster network administrators, cluster security administrators and DevOps engineers by providing a centralized platform for monitoring application and network health, and security. Retina is capable of collecting telemetry data from multiple sources and aggregating it into a single time-series database. Retina is also capable of sending data to multiple destinations, such as Prometheus, Azure Monitor, and other vendors, and visualizing the data in a variety of ways, like Grafana, Azure Monitor, Azure log analytics, and more.
+
+## Documentation
+
+See [retina.sh](http://retina.sh) for more information and examples.
+
+## Capabilities
+
+Retina is currently supported in AKS. It has two major features:
+
+### Metrics
+
+[Read more](docs/metrics/intro.md)
+
+### Quick Install Guide
+
+1. Create a Kubernetes cluster with a minimum of 2 nodes. Retina supports Linux (Ubuntu) and Windows (2019 and 2022) nodes.
+2. Follow steps in [Using Managed Prometheus and Grafana](https://retina.sh/docs/metrics/managed-retina)

+# Capture CRD
+
+## Overview
+
+The `Capture` CustomResourceDefinition (CRD) defines a custom resource called `Capture`, which represents the settings of a network trace.
+This CRD allows users to specify the configurations for capturing network packets and storing the captured data.
+
+To use the `Capture` CRD, [install Retina](../installation/setup.md) with capture support.
+
+## CRD Specification
+
+The full specification for the `Capture` CRD can be found in the [Capture CRD](https://github.com/microsoft/retina/blob/main/deploy/manifests/controller/helm/retina/crds/retina.io_captures.yaml) file.
+
+The `Capture` CRD is defined with the following specifications:
+
+- **API Group:** retina.io
+- **API Version:** v1alpha1
+- **Kind:** Capture
+- **Plural:** captures
+- **Singular:** capture
+- **Scope:** Namespaced
+
+### Fields
+
+- **spec.captureConfiguration:** Specifies the configuration for capturing network packets. It includes the following properties:
+  - `captureOption`: Lists options for the capture, such as duration, maximum capture size, and packet size.
+  - `captureTarget`: Defines the target on which the network packets will be captured. It includes namespace, node, and pod selectors.
+  - `filters`: Specifies filters for including or excluding network packets based on IP or port.
+  - `includeMetadata`: Indicates whether networking metadata should be captured.
+  - `tcpdumpFilter`: Allows specifying a raw tcpdump filter string.
+
+- **spec.outputConfiguration:** Indicates where the captured data will be stored. It includes the following properties:
+  - `blobUpload`: Specifies a secret containing the blob SAS URL for storing the capture data.
+  - `hostPath`: Stores the capture files into the specified host filesystem.
+  - `persistentVolumeClaim`: Mounts a PersistentVolumeClaim into the Pod to store capture files.
+
+- **status:** Describes the status of the capture, including the number of active, failed, and completed jobs, completion time, conditions, and more. Check [capture lifecycle](#capture-lifecycle) for more details.
+
+## Usage
+
+### Creating a Capture
+
+To create a `Capture`, create a YAML manifest file with the desired specifications and apply it to the cluster using `kubectl apply`:
+
+```yaml
+apiVersion: retina.io/v1alpha1
+kind: Capture
+metadata:
+  name: example-capture
+spec:
+  captureConfiguration:
+    captureOption:
+      duration: "30s"
+      maxCaptureSize: 100
+      packetSize: 1500
+    captureTarget:
+      namespaceSelector:
+        matchLabels:
+          app: target-app
+  outputConfiguration:
+    hostPath: /captures
+    blobUpload: blob-sas-url
+```
+
+### Capture Lifecycle
+
+Once a Capture is created, the capture controller inside retina-operator is responsible for managing the lifecycle of the Capture.
+A Capture can be turned into error when errors happens like no required selector is specified, or InProgress when created workload are running, or completed when all workloads are completed.
+In implementation, the complete status is defined by setting complete status condition to true, and InProgress is defined as a false complete status condition.
+
+#### Examples of Capture status
+
+- No allowed selectors are specified
+
+```yaml
+Status:
+  Conditions:
+    Last Transition Time:  2023-10-23T06:17:39Z
+    Message:               Neither NodeSelector nor NamespaceSelector&PodSelector is set.
+    Reason:                otherError
+    Status:                True
+    Type:                  error
+```
+
+- Capture is running in progress
+
+```yaml
+Status:
+  Active:  2
+  Conditions:
+    Last Transition Time:  2023-10-23T06:33:56Z
+    Message:               2/2 Capture jobs are in progress, waiting for completion
+    Reason:                JobsInProgress
+    Status:                False
+    Type:                  complete
+```
+
+- Capture is completed
+
+```yaml
+Status:
+  Completion Time:  2023-10-23T06:34:40Z
+  Conditions:
+    Last Transition Time:  2023-10-23T06:34:40Z
+    Message:               All 2 Capture jobs are completed
+    Reason:                JobsCompleted
+    Status:                True
+    Type:                  complete
+  Succeeded:               2
+```

+# MetricsConfiguration CRD
+
+## Overview
+
+Retina by default emits node level metrics, however, customers can apply `MetricsConfiguration`  custom resource definition (CRD) to enable advanced metrics and they can define in which namespaces the advanced metrics to be enabled.  
+
+## CRD Specification
+
+The full specification for the `MetricsConfiguration` CRD can be found in the [MetricsConfiguration CRD](https://github.com/microsoft/retina/blob/main/deploy/manifests/controller/helm/retina/crds/retina.io_metricsconfigurations.yaml) file.
+
+The `MetricsConfiguration` CRD is defined with the following specifications:
+
+- **API Group:** retina.io
+- **API Version:** v1alpha1
+- **Kind:** MetricsConfiguration
+- **Plural:** metricsconfigurations
+- **Singular:** metricsconfiguration
+- **Scope:** Cluster
+
+### Fields
+
+- **spec.contextOptions:** Specifies the configuration for retina plugin metrics context. It includes the following properties:
+  - `additionalLabels`: Represents additional context labels to be collected, such as Direction (ingress/egress).
+  - `destinationLabels`: Represents the destination context labels, such as IP, Pod, port, workload (deployment/replicaset/statefulset/daemonset).
+  - `metricName`: Indicates the name of the metric.
+  - `sourceLabels`: Represents the source context labels, such as IP, Pod, port.
+
+- **spec.namespaces:** Specifies the namespaces to include or exclude in metric collection. It includes the following properties:
+  - `exclude`: Specifies namespaces to be excluded from metric collection.
+  - `include`: Specifies namespaces to be included in metric collection.
+
+- **status:** Describes the status of the metrics configuration, including the last known specification, reason, and state.
+
+## Usage
+
+### Creating a MetricsConfiguration
+
+To create a `MetricsConfiguration`, create a YAML manifest file with the desired specifications and apply it to the cluster using `kubectl apply`:
+
+```yaml
+apiVersion: retina.io/v1alpha1
+kind: MetricsConfiguration
+metadata:
+  name: metricsconfigcrd
+spec:
+  contextOptions:
+    - metricName: drop_count
+      sourceLabels:
+        - ip
+        - podname
+        - port
+      additionalLabels:
+        - direction
+    - metricName: forward_count
+      sourceLabels:
+        - ip
+        - podname
+        - port
+      additionalLabels:
+        - direction
+  namespaces:
+    include:
+      - default
+      - kube-system
+```
+
+## Validation of MetricsConfiguration CRD
+
+The **Operator Pod** acts as a validator for customer-applied CRDs. It reads metrics and/or traces CRDs, validates options, and updates the status of the applied CRDs accordingly.
+
+### Status States
+
+The status of the CRD can be one of the following:
+
+1. **Initiated (optional)**: The initial state upon CRD application. The Operator may set it to "Initiated" when the CRD is first applied. This state can be skipped for simplicity.
+
+2. **Accepted**: After validating the CRD options, the Operator transitions the status to "Accepted" if everything is valid.
+
+3. **Error**: In case of validation issues, the Operator updates the status to "Error" along with a reason for the CRD's invalidity.
+
+### Interaction with Daemon Pods
+
+Daemon Pods wait for the "Accepted" status before applying configurations. This ensures only validated configurations are processed, reducing errors.
+
+After validation, the following section is added to the CRD:
+
+```yaml
+status:
+  state: Initialized/Accepted/Errorred
+  reason: <error reason if any>
+  acceptedSpec: <Operator accepted last known spec>
+```

+# RetinaEndpoint CRD
+
+## Overview
+
+The `RetinaEndpoint` CustomResourceDefinition (CRD) defines a custom resource called `RetinaEndpoint`, which is a representation of a Kubernetes Pod. This CRD allows users to define and manage additional information about Pod  beyond the default Kubernetes metadata as well as reduce the complexity.
+
+In large-scale API servers, each Retina Pod needs to learn about cluster state, which requires the API server to push a lot of data for each list and watch event. To address this issue, we need to reduce the Pod object and convert it to a more manageable `RetinaEndpoint` object.
+
+## CRD Specification
+
+The full specification for the `RetinaEndpoint` CRD can be found in the [RetinaEndpoint CRD]( https://github.com/microsoft/retina/blob/main/deploy/manifests/controller/helm/retina/crds/retina.io_retinaendpoints.yaml) file.
+
+The `RetinaEndpoint` CRD is defined with the following specifications:
+
+- **API Group:** retina.io
+- **API Version:** v1alpha1
+- **Kind:** RetinaEndpoint
+- **Plural:** retinaendpoints
+- **Singular:** retinaendpoint
+- **Scope:** Namespaced
+
+### Fields
+
+- **spec.containers:** An array of container objects associated with the endpoint. Each container object has an `id` and a `name`.
+
+- **spec.labels:** A set of labels to apply to the endpoint.
+
+- **spec.nodeIP:** The IP address of the node associated with the endpoint.
+
+- **spec.ownerReferences:** An array of owner references indicating the resources that own the endpoint.
+
+- **spec.podIP:** The IP address of the Pod associated with the endpoint.
+
+## Usage
+
+### Creating a RetinaEndpoint
+
+To create a `RetinaEndpoint`, create a YAML manifest file with the desired specifications and apply it to the cluster using `kubectl apply`:
+
+```yaml
+apiVersion: retina.io/v1alpha1
+kind: RetinaEndpoint
+metadata:
+  name: example-retinaendpoint
+  namespace: test
+  labels:
+    app: example-app
+spec:
+  containers:
+    - id: container-1
+      name: web
+  nodeIP: 192.168.1.10
+  ownerReferences:
+    - apiVersion: v1
+      kind: Pod
+      name: example-pod
+  podIP: 10.1.2.3
+
+```
+
+## RetinaEndpoint Workflow
+
+In high-scale Kubernetes environments, the scenario where each DaemonSet Pod monitors all Pods within a cluster can lead to a significant volume of data propagation. This situation can potentially strain the API server and cause performance issues.
+To address this challenge, an **Operator Pod** is introduced to streamline data flow.
+
+The **Operator** plays a pivotal role in transforming extensive Pod objects into succinct `RetinaEndpoints`. These `RetinaEndpoints` contain only the crucial fields required for Retina functionality. This approach efficiently reduces data size, enabling rapid propagation across all nodes. The subsequent sections delve into the intricacies of this process.
+
+### Workflow Steps
+
+1. **Operator's Monitoring**: When advanced features are enabled, the **Operator** component will monitor the Kubernetes cluster for Pods. It is the only one that can watch and update the `RetinaEndpoint` Resource.
+
+2. **Data Extraction and Transformation**: The **Operator** extracts relevant Pod information and uses this data to generate a corresponding `RetinaEndpoint` CustomResource (CR) object.
+
+3. **Data Backup**: The newly created `RetinaEndpoint` CR object is backed up to the Kubernetes API server by the **Operator**.
+
+4. **Daemon's Role**: The K8s watchers in daemon set Pods will list and read `RetinaEndpoints` and Service objects from the API server.
+
+5. **Data Enrichment**: Subsequently, these K8s watchers convert these objects into an internal cache, enriching kernel data for efficient usage.

+# Capture with Retina CLI
+
+Retina capture command allows the user to capture network traffic and metadata for the capture target, and then send the capture file to the location by Output Configuration.
+
+Note: captures can also be performed with a [Capture CRD](../CRDs/Capture.md) after [installing Retina](../installation/setup.md) with capture support.
+
+## Retina capture create
+
+`retina capture create` creates a Capture with underlying Kubernetes jobs.
+
+### No wait(default true)
+
+Do not wait for the long-running capture job to finish.
+By default, Retina capture CLI will exit before the jobs are completed. With `--no-wait=false`, the CLI will wait until the jobs are completed and clean up the Kubernetes resources created.
+
+#### Example
+
+- do not wait for the long-running capture job to finish
+
+`kubectl retina capture create --host-path /mnt/capture --node-selectors "kubernetes.io/os=linux" --no-wait=true`
+
+### Namespace(default "default")
+
+Namespace to host capture job and the other k8s resources for a network capture. Please make sure the namespace exists.
+
+#### Example
+
+- deploy the capture job in namespace `capture`
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --node-selectors "kubernetes.io/os=linux"`
+
+### Capture Target(required)
+
+Capture target indicates the target on which the network packets capture will be performed, and the user can select either node, by node-selectors or node-names, or Pods, by pod-selector and namespace-selector pair.
+
+#### Examples
+
+- capture network packets on the node selected by node selectors
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --node-selectors "kubernetes.io/os=linux"`
+
+- capture network packets on the node selected by node names
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --node-names "aks-nodepool1-41844487-vmss000000,aks-nodepool1-41844487-vmss000001"`
+
+- capture network packets on the pod selected by pod-selector and namespace-selector pairs
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --pod-selectors="k8s-app=kube-dns" --namespace-selectors="kubernetes.io/metadata.name=kube-system"`
+
+### Stop Capture(optional with default values)
+
+The Capture can be stopped in either way below:
+
+- In a given time, by the `duration` flag, or when the allowed maximum capture file reaches by the `max-size` flag. When both are specified, the capture will stop when either condition first meets.
+- On demand by deleting the capture before the specified conditions meets.
+
+The network traffic will be uploaded to the specified output location.
+
+#### Capture Duration
+
+Duration of capturing packets(default 1m)
+
+##### Example
+
+- stop the capture in 2 minutes
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --node-selectors "kubernetes.io/os=linux" --duration=2m`
+
+#### Maximum Capture Size
+
+Limit the capture file to MB in size(default 100MB)
+
+##### Example
+
+- stop the capture when the capture file size reaches 50MB
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --node-selectors "kubernetes.io/os=linux" --max-size=50`
+
+#### Packet Size(optional)
+
+Limits the each packet to bytes in size and packets longer than PacketSize will be truncated.
+This is beneficial when the user wants to reduce the capture file size or hide customer data for security concern.
+
+##### Example
+
+- limit each packet size to 96 bytes
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --node-selectors "kubernetes.io/os=linux" --packet-size=96`
+
+### Capture Configuration(optional)
+
+capture configuration indicates the configurations of the network capture.
+
+#### Packet capture filters
+
+Packet capture filters represent a range of filters to be included/excluded in the capture. This is not available on Windows.
+
+##### Example
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --node-selectors "kubernetes.io/os=linux" --exclude-filter="10.224.0.26:80,10.224.0.33:8080" --include-filter="10.224.0.42:80,10.224.0.33:8080"`
+
+#### Tcpdump Filter
+
+Raw tcpdump flags which works only for Linux. Available tcpdump filters can be found in [TCPDUMP MAN PAGE](https://www.tcpdump.org/manpages/tcpdump.1.html)
+NOTE: this includes only tcpdump flags, for expression part, please user [Packet include/exclude filters
+](#packet-capture-filters).
+
+##### Example
+
+- filter DNS query
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --node-selectors "kubernetes.io/os=linux" --tcpdump-filter="udp port 53"`
+
+#### Include Metadata
+
+If true, collect static network metadata into the capture file(default true)
+
+##### Example
+
+- disable collecting network metadata
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --node-selectors "kubernetes.io/os=linux" --include-metadata=false`
+
+### Job Number Limit(optional)
+
+The maximum number of jobs can be created for each capture. The default value 0 indicates no limit.
+This can be configured by CLI flags for each CLI command, or config map consumed by retina-operator.
+When creating a job requires job number exceeds this limit, it will fail with prompt like
+`Error: the number of capture jobs 3 exceeds the limit 2`
+
+#### Example
+
+`kubectl retina capture create --job-num-limit=10 --host-path /mnt/capture --namespace capture --node-selectors "kubernetes.io/os=linux"`
+
+### Output Configuration(required)
+
+OutputConfiguration indicates the location capture will be stored, and at least one location should be specified.
+
+Blob-upload requires a Blob Shared Access Signature with the write permission to the storage account container, to create SAS tokens in the Azure portal, please read [Create SAS Tokens in the Azure Portal](https://learn.microsoft.com/en-us/azure/cognitive-services/translator/document-translation/how-to-guides/create-sas-tokens?tabs=Containers#create-sas-tokens-in-the-azure-portal)
+
+#### Examples
+
+- store the capture file in the node host path `/mnt/capture`
+
+`kubectl retina capture create --host-path /mnt/capture --namespace capture --node-selectors "kubernetes.io/os=linux"`
+
+- store the capture file to a PVC `mypvc` with access mode ReadWriteMany in namespace `capture`
+
+`kubectl retina capture create --pvc mypvc --namespace capture --node-selectors "kubernetes.io/os=linux"`
+
+- store the capture file to a storage account
+
+`kubectl retina capture create --blob-upload <Blob SAS URL with write permission> --node-selectors "kubernetes.io/os=linux"`
+
+### Debug mode
+
+With debug mode, when `--debug` is specified, we can overwrite the capture job Pod image from the default official `MCR` one.
+
+#### Examples
+
+- use `acnpublic` ACR in default debug mode
+
+`kubectl retina capture create --host-path /mnt/test --namespace capture --node-selectors "kubernetes.io/os=linux" --debug`
+
+- use customized retina-agent image
+
+`RETINA_AGENT_IMAGE=<YOUR RETINA AGENT IMAGE> kubectl retina capture create --host-path /mnt/test --namespace capture --node-selectors "kubernetes.io/os=linux" --debug`
+
+## Retina capture delete
+
+`retina capture delete` deletes a Kubernetes Jobs with the specified Capture name.
+
+### Examples
+
+`kubectl retina capture delete --name retina-capture-zlx5v`
+
+## Retina capture list
+
+`retina capture list` lists Captures in a namespace or all namespaces.
+
+### Examples
+
+- list Captures under namespace `capture`
+
+`kubectl retina capture list --namespace capture`
+
+- list Captures under in all namespaces
+
+`kubectl retina capture list --all-namespaces`
+
+## Obtain the output
+
+After downloading or copying the tarball from the location specified, extract the tarball through the `tar` command in either Linux shell or Windows Powershell, for example,
+
+```shell
+tar -xvf retina-capture-aks-nodepool1-41844487-vmss000000-20230320013600UTC.tar.gz
+```
+
+### Name pattern of the tarball
+
+the tarball take such name pattern, `$(capturename)-$(hostname)-$(date +%Y%m%d%H%M%S%Z).tar.gz`, for example, `retina-capture-aks-nodepool1-41844487-vmss000000-20230313101436UTC.tar.gz`.

+# Captures
+
+## Overview
+
+Retina Capture allows users to capture network traffic/metadata for the specified Nodes/Pods.
+
+Captures are on-demand and can be output to the host filesystem, a storage blob, etc.
+
+## Usage
+
+There are two methods for triggering a Capture:
+- [CLI command](#option-1-retina-cli) or
+- [CRD/YAML configuration](#option-2-capture-crd-custom-resource-definition).
+
+### Option 1: Retina CLI
+
+Available after [Installing Retina CLI](../installation/cli.md).
+
+See [Capture Command](../captures/cli.md) for more details.
+
+#### Example
+
+This example captures network traffic for all Linux Nodes, storing the output in the folder */mnt/capture* on each Node.
+
+```shell
+kubectl-retina capture create --host-path /mnt/capture --node-selectors "kubernetes.io/os=linux"
+```
+
+#### Architecture
+
+For each Capture, a Kubernetes Job is created for each relevant Node (the Node could be selected and/or could be hosting a selected Pod).
+The Job's worker Pod runs for the specified duration, captures and wraps the network information into a tarball, and copies the tarball to the specified output location(s).
+As a special case, a Kubernetes secret will be created containing a storage blob SAS for security concerns, then mounted to the Pod.
+
+A random hashed name is assigned to each Retina Capture to uniquely label it.
+
+![Overview of Retina Capture without operator](img/capture-architecture-without-operator.png "Overview of Retina Capture without operator")
+
+### Option 2: Capture CRD (Custom Resource Definition)
+
+Available after after [installing Retina](../installation/setup.md) with capture support.
+
+See [Capture CRD](../CRDs/Capture.md) for more details.
+
+#### Example
+
+This example creates a Capture and stores the Capture artifacts into a storage account specified by Blob SAS URL.
+
+Create a secret to store blob SAS URL:
+
+```yaml
+apiVersion: v1
+data:
+  ## Data key is required to be "blob-upload-url"
+  blob-upload-url: <based-encode-blob-sas-url>
+kind: Secret
+metadata:
+  name: blob-sas-url
+  namespace: default
+type: Opaque
+```
+
+Create a Capture specifying the secret created as blobUpload, this example will also store the artifact on the node host path
+
+```yaml
+apiVersion: retina.io/v1alpha1
+kind: Capture
+metadata:
+  name: capture-test
+spec:
+  captureConfiguration:
+    captureOption:
+      duration: 30s
+    captureTarget:
+      nodeSelector:
+        matchLabels:
+          kubernetes.io/hostname: aks-nodepool1-11396069-vmss000000
+  outputConfiguration:
+    hostPath: "/tmp/retina"
+    blobUpload: blob-sas-url
+```
+
+More Retina Capture samples can be found [here](https://github.com/microsoft/retina/tree/main/samples/capture)
+
+#### Architecture
+
+Similarly to Option 1, a Kubernetes Job is created for each relevant Node.

+
+## Development
+
+### Configurations
+
+FIXME just link the Config page
+
+Configurations are passed through `retina-config` configmap in `retina` namespace. Following configurations are currently supported:
+
+- `apiserver.port` : the port for `retina-agent` Pod
+- `logLevel` : supported - `debug`, `info`, `error`, `warn`, `panic`, `fatal`
+- `enabledPlugin` : eBPF plugins to be installed in worker node. Currently supported plugins are `dropreason` and `packetforward`
+- `metricsInterval` : interval, in seconds, to scrape/publish metrics
+
+Note: Changes to configmap after retina is deployed would require re-deployment of `retina-agent`.
+
+### Supported Metrics Plugins
+
+FIXME just link metrics page
+
+### Pre-Requisites
+
+```bash
+export LLVM_VERSION=14
+curl -sL https://apt.llvm.org/llvm.sh  | sudo bash -s "$LLVM_VERSION"
+```
+
+Download [Helm](https://helm.sh/) as well.
+
+### Test
+
+```bash
+make retina-ut # run unit-test locally
+make retina-test-image # run tests in docker container
+```

+```
+
+To build a `retina-agent` container image with specific tag:
+
+```bash
+TAG=<tag> make retina-image
+```
+
+To build binary of a plugin and test it
+
+```bash
+# Test packetforward.
+$ cd <Retina_repository>/test/plugin/packetforward
+$ 
+$ go build . && sudo ./packetforward
+info    metrics Metrics initialized
+info    packetforward   Packet forwarding metric initialized

+debug   packetforward   Received PacketForward data     {"Data": "IngressBytes:898 IngressPackets:12 EgressBytes:23808 EgressPackets:70"}
+...
+```
+
+### Deploying Locally on Kind
+
+```bash
+make kind-setup # This deploys a Kind cluster and installs azure NPM
+make retina-image && make kind-install # Skip building image if already done
+make kind-clean # Delete Kind cluster

+# Retina Config
+
+## Overview
+
+To customize metrics and other options, you can modify Retina's ConfigMap called `retina-config`.
+Defaults are specified for each component in *deploy/manifests/controller/helm/retina/values.yaml*.
+
+## Agent Config
+
+* `enablePodLevel`: When this toggle is set to true, Retina will gather Advanced/Pod-Level metrics. Advanced metrics can attach Pod metadata to Retina's metrics.
+* `remoteContext`: When this toggle is set to true, retina will watch Pods on the cluster.
+* `enableAnnotations`: When this toggle is set to true, retina will gather metrics for the annotated resources. Namespaces or Pods can be annotated with "retina.io/v1alpha=observe". The operator and enableRetinaEndpoint for the operator should be enabled.
+* `enabledPlugin_linux`: Array of enabled plugins for linux.
+* `enabledPlugin_win`: Array of enabled plugins for windows.
+* `metricsInterval`: the interval for which metrics will be gathered.
+
+## Operator Config
+
+* `installCRDs`: When this toggle is set, the operator will handle installing Retina-related CRDs.
+* `enableRetinaEndpoint`: When this toggle is set, the operator will watch and update the cache with Pod metadata.

+# Configuring Grafana
+
+## Pre-Requisites
+
+Follow either:
+
+- [Unmanaged Prometheus/Grafana](./prometheus-unmanaged.md) or
+- [Azure-Hosted Prometheus/Grafana](prometheus-azure-managed.md).
+
+Make sure that you're still port-forwarding your server to localhost:9090, or configure your server for some other HTTP endpoint.
+
+## Configuration
+
+1. Check Grafana to make sure the managed Prometheus datasource exists:
+
+   ![alt text](img/portal-grafana.png)
+
+2. Go to the dashboard page and select "import":
+
+   ![alt text](img/grafana-dashboard-import.png)
+
+3. Import the [published dashboards](https://grafana.com/grafana/dashboards/) by ID, or import the dashboards by JSON at *deploy/grafana/dashboards/*.
+
+4. The Grafana dashboard should now be visible.
+
+   ![alt text](img/grafana-dashboard.png)
+
+FIXME add published dashboard links
+
+## Pre-Installed Dashboards

+4. Link both the Azure Monitor Workspace and Grafana instance to your cluster:
+
+   ```shell
+   az aks update --enable-azure-monitor-metrics \
+     -n $NAME \
+     -g $RESOURCE_GROUP \
+     --azure-monitor-workspace-resource-id $AZMON_RESOURCE_ID \
+     --grafana-resource-id  $GRAFANA_RESOURCE_ID
+   ```
+
+5. Verify that the Azure Monitor Pods are running. For example:
+
+   ```shell
+   kubectl get pod -n kube-system
+   ```
+
+   ```shell
+   NAME                                  READY   STATUS    RESTARTS   AGE
+   ama-metrics-5bc6c6d948-zkgc9          2/2     Running   0          26h

+   ama-metrics-win-node-tkrm8            2/2     Running   0          26h
+   ```
+
+6. Verify that the Retina Pods are discovered by port-forwarding an AMA node Pod:
+
+   ```bash
+   kubectl port-forward -n kube-system $(kubectl get pod -n kube-system -l dsName=ama-metrics-node -o name | head -n 1) 9090:9090
+   ```
+
+   ```bash
+   Forwarding from 127.0.0.1:9090 -> 9090
+   Forwarding from [::1]:9090 -> 9090
+   ```
+
+7. Then go to [http://localhost:9090/targets](http://localhost:9090/targets) to see the Retina Pods being discovered and scraped:

+  ```shell
+  helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
+  helm repo update
+  ```
+
+2. Install the Prometheus chart
+
+  ```shell
+  helm install prometheus -n kube-system -f deploy/prometheus/values.yaml prometheus-community/kube-prometheus-stack
+  ```
+
+3. Save the Prometheus values below to `deploy/prometheus/values.yaml`
+
+  ```yaml
+  prometheus:
+    prometheusSpec:
+      additionalScrapeConfigs: |
+        - job_name: "retina-pods"

+            - role: pod
+          relabel_configs:
+            - source_labels: [__meta_kubernetes_pod_container_name]
+              action: keep
+              regex: retina(.*)
+            - source_labels:
+                [__address__, __meta_kubernetes_pod_annotation_prometheus_io_port]
+              separator: ":"
+              regex: ([^:]+)(?::\d+)?
+              target_label: __address__
+              replacement: ${1}:${2}
+              action: replace
+            - source_labels: [__meta_kubernetes_pod_node_name]
+              action: replace
+              target_label: instance
+          metric_relabel_configs:
+            - source_labels: [__name__]
+              action: keep
+              regex: (.*)
+  ```
+
+4. Upgrade deployment with
+
+  ```shell
+  helm upgrade prometheus -n kube-system -f deploy/prometheus/values.yaml prometheus-community/kube-prometheus-stack
+  ```
+
+5. Install Retina
+
+  ```shell
+  helm install retina ./deploy/manifests/controller/helm/retina/ --namespace kube-system --dependency-update
+  ```
+
+6. Verify that the Retina Pods are being scraped by port-forwarding the Prometheus server:
+
+  ```shell
+  kubectl port-forward --namespace kube-system svc/prometheus-operated 9090
+  ```
+
+7. Then go to [http://localhost:9090/targets](http://localhost:9090/targets) to see the Retina Pods being discovered and scraped:

+# Introduction to Retina
+
+## What is Retina?
+
+Retina is a cloud-agnostic, open-source **Kubernetes Network Observability platform** which helps with DevOps, SecOps and compliance use cases.
+It provides a **centralized hub for monitoring application and network health and security**, catering to Cluster Network Administrators, Cluster Security Administrators and DevOps Engineers.
+
+Retina **collects customizable telemetry**, which can be exported to **multiple storage options** (such as Prometheus, Azure Monitor, and other vendors) and **visualized in a variety of ways** (like Grafana, Azure Log Analytics, and other vendors).
+
+## Features
+
+- **[eBPF](https://ebpf.io/what-is-ebpf#what-is-ebpf)-based** Network Observability platform for Kubernetes workloads.
+- **On-Demand** and **Configurable**.
+- Actionable, industry-standard **Prometheus metrics**.
+- Streamlined **Packet Captures** for deep dives.
+- **Cloud-agnostic**, supporting multiple OS (like Linux, Windows, Azure Linux).
+
+## Why Retina?
+
+Retina lets you **investigate network issues on-demand** and **continuously monitor your clusters**. Here are a couple scenarios where Retina shines, minimizing pain points and investigation time.
+
+### Investigations: Debugging Network Connectivity
+
+*Why can't my Pods connect to each other any more?* **Typical investigation is time-intensive** and involves performing packet captures, where one must identify the Nodes involved, gain access to each Node, run `tcpdump` commands, and export the results off of each Node.
+
+With Retina, you can **automate this process** with a **single CLI command** or CRD/YAML that can:
+- Run captures on all Nodes hosting the Pods of interest.
+- Upload each Node's results to a storage blob.
+
+To begin using the CLI, see [Quick Start Installation](./installation/cli.md).
+
+### Monitoring Network Health
+
+Retina supports actionable insights through **Prometheus** alerting, **Grafana** dashboards, and more. For instance, you can:
+
+- Monitor dropped traffic in a namespace.
+- Alert on a spike in production DNS errors.
+- Watch changes in API Server latency while testing your application's scale.
+- Notify your Security team if a Pod starts sending too much traffic.
+
+## Telemetry
+
+Retina uses two types of telemetry: metrics and captures.
+
+### Metrics
+
+Retina metrics provide **continuous observability** into:
+- Incoming/outcoming traffic
+- Dropped packets
+- TCP/UDP
+- DNS
+- API Server latency
+- Node/interface statistics
+
+Retina provides both:
+- **Basic metrics** (default, Node-Level metrics) and
+- **Advanced/Pod-Level metrics** (if enabled).
+
+For more info and a list of metrics, see [Metrics](metrics/modes.md).
+
+### Captures
+
+A Retina capture **logs network traffic** and metadata **for the specified Nodes/Pods**.
+
+Captures are **on-demand** and can be output to multiple destinations. For more info, see [Captures](captures/readme.md).
+
+## Extendable Architecture
+
+Retina supports **several options for storage and insights/visualization**. Below is the high-level architecture for Retina, conveying some of these options.

+# Advanced Metrics
+
+There are two Advanced modes (see [Metric Modes](./modes.md)) which include all [Basic Metrics](./basic.md) plus extra metrics providing Pod-Level context.
+
+The two Advanced modes are *remote context* and *local context*. The difference lies in the [Context Labels](#context-labels).
+Additionally, *local context* supports [Annotations](./annotations.md).
+
+## Prefix
+
+All metrics have the prefix `networkobservability_`.
+
+## Universal Labels
+
+Node and Cluster metadata are included with the labels:
+- `cluster`
+- `instance` (Node name)
+
+## Context Labels
+
+There are Pod-Level context labels for metrics prepended with `adv_`.
+
+To customize context labels, see [MetricsConfiguration CRD](../CRDs/MetricsConfiguration.md).
+
+### Remote Context
+
+For Advanced mode with *remote context*, default context labels are the following:
+- `source_ip`
+- `source_namespace`
+- `source_pod`
+- `source_workload`
+- `destination_ip`
+- `destination_namespace`
+- `destination_pod`
+- `destination_workload`
+
+### Local Context
+
+For Advanced mode with *local context*, default context labels are the following for *outgoing* traffic:
+- `source_ip`
+- `source_namespace`
+- `source_pod`
+- `source_workload`
+
+For *incoming* traffic:
+- `destination_ip`
+- `destination_namespace`
+- `destination_pod`
+- `destination_workload`
+

+# Metric Modes
+
+Retina provides **three modes** with their own metrics and scale capabilities.
+Each mode is **fully customizable** (only create the metrics/labels you need).
+
+Note that below, "metric cardinality" refers to the number of time series (metric values with a unique set of labels).
+The larger the cardinality, the more load induced on a Prometheus server for instance.
+

+## Where Do Metrics Come From?
+
+A Retina agent generates metrics on each Node.
+The Linux agent inserts eBPF programs and gathers data from Linux utilities.
+The Windows agent gathers data from HNS and VFP.

+
+See *pkg/plugin/dropreason/drop_reason.c*:
+
+```c

+    __u64 bytes;
+};
+
+```
+
+### eBPF Hook Points for Drop Reason
+
+| Reason | Description | eBPF Hook Point |

+# `linuxutil` (Linux)
+
+Gathers TCP/UDP statistics and network interface statistics from the `netstats` and `ethtool` Node utilities (respectively).
+
+## Metrics
+
+See metrics for [Basic Mode](../basic.md#plugin-linuxutil-linux) (Advanced modes have identical metrics).
+
+## Architecture
+
+The plugin uses the following utilities as data sources:
+
+1. `netstat`
+    - TCP Socket information
+    - UDP Socket information
+    - "/proc/net/netstat" for IP and UDP statistics
+2. `ethtool`
+    - Interface statistics
+
+### Code Locations
+
+- Plugin code interfacing with the Node utilities: *pkg/plugin/linuxutil/*
+
+### Configuration (in Code)
+
+Both `ethtool` and `netstat` data can be curated to remove unwanted data. Below options in a struct in *linuxutil.go* can be used to configure the same.
+
+```go
+type EthtoolOpts struct {
+	// when true will only include keys with err or drop in its name
+	errOrDropKeysOnly bool
+
+	// when true will include all keys with value 0
+	addZeroVal bool
+}
+```
+
+```go
+type NetstatOpts struct {
+	// when true only includes curated list of keys
+	CuratedKeys bool
+
+	// when true will include all keys with value 0
+	AddZeroVal bool
+
+	// get only listening sockets
+	ListenSock bool
+}
+```
+
+These are initialized in the linuxutil.go file.
+

+# Basic Metrics TSG
+
+## Overview
+
+Basic metrics is covered by the [Metrics](../metrics/intro.md) section of the Retina documentation. This guide is intended to help you troubleshoot issues with basic metrics.
+
+## Metrics are not being generated or showing up in Grafana dashboards
+
+If you are not seeing metrics in Grafana, it is likely that the metrics are not being generated. To troubleshoot this issue, you can check the following:
+
+### Check Retina Pods are running
+
+Check that all Retina Pods are running. You can do this by running the following command:
+
+```shell
+kubectl get pods -n kube-system -l k8s-app=retina
+```
+
+If any of the pods are not running, you can describe the Pod to see what the issue is. You can do this by running the following command:
+
+```shell
+kubectl describe pod -n kube-system <retina pod name>
+```
+
+### Check Retina Pod Logs
+
+If retina Pods are running, you can check the logs for the Pod to see what the issue is. You can do this by running the following command:
+
+```shell
+kubectl logs -n kube-system <retina pod name>
+```
+
+you should see log lines like the following:
+
+```shell
+2023-04-15T23:52:08.046Z        info    dropreason      dropreason/dropreason_linux.go:208      DropReason data collection complete
+2023-04-16T00:10:55.598Z        info    linuxutil       linuxutil/linuxutil.go:100      Updated ethTool metrics
+```
+
+### Check Retina ConfigMap
+
+If not then the plugin is not running correctly. Please check retina config map and make sure the plugins is enabled.
+
+```shell
+kubectl get configmap retina-config -n kube-system -oyaml
+```
+
+```yaml
+apiVersion: v1
+data:
+  config.yaml: |-
+    apiServer:
+      host: 0.0.0.0
+      port: 10093
+    logLevel: info
+    enabledPlugin: ["dropreason","packetforward","linuxutil"]
+    metricsInterval: 10
+    enableTelemetry: true
+kind: ConfigMap
+metadata:
+  annotations:
+    meta.helm.sh/release-name: retina
+    meta.helm.sh/release-namespace: kube-system
+  creationTimestamp: "2023-04-13T21:56:08Z"
+  labels:
+    app.kubernetes.io/managed-by: Helm
+  name: retina-config
+  namespace: kube-system
+  resourceVersion: "427462"
+  uid: 1d45f43a-2db5-4f93-a467-aca106ac3fcb
+  ```
+
+### Check Retina Metrics are being generated
+
+You can check that metrics are being generated by calling the metrics endpoint. You can do this by running the following command from inside one of the nodes:
+
+```shell
+curl http://<retina-pod-ip>:10093/metrics | grep -i retina
+```
+
+You should see metrics like the following:
+
+```shell
+# HELP retina_forward_bytes Total forwarded bytes
+# TYPE retina_forward_bytes gauge
+retina_forward_bytes{direction="egress"} 1.9064666952e+10

+# HELP retina_udp_connection_stats UDP connections Statistics
+# TYPE retina_udp_connection_stats gauge
+retina_udp_connection_stats{statistic_name="ACTIVE"} 5
+```
+
+If you are not seeing metrics like the above, then the plugin is not running correctly. Please check retina config map and make sure the plugins is enabled.
+
+### Check if Managed Prometheus is scraping Retina metrics
+
+If you are using managed Prometheus, you can check if it is scraping the retina metrics by following below steps.
+
+1. Check if AMA-Metrics Pods are running
+
+    ```shell
+    kubectl get pods -n kube-system -l dsName=ama-metrics-node
+    ```
+
+2. If they are running, then port forward one of the AMA metrics Pods to see if it can identify retina Pods
+
+    ```shell
+    kubectl port-forward -n kube-system <ama-metrics-pod-name> 9090:9090
+    ```
+
+3. Open the following URL in your browser to see if retina Pods are being discovered
+
+    ```shell
+    http://localhost:9090/targets
+    ```
+
+    ![alt text](imgs/prometheus-retina-targets.png)
+
+    a. check if service discovery is recognizing retina Pods
+
+    ```shell
+    http://localhost:9090/service-discovery#retina-pods
+    ```
+
+    ![alt text](imgs/prom-retina-service-discovery.png)
+
+4. If Retina Pods are not discovered then please check prometheus configuration and make sure the Retina Pod's job is added to the scrape config.
+
+    ```shell
+    http://localhost:9090/config
+    ```
+
+    ![alt text](imgs/prom-retina-config.png)
+
+5. If the Retina Pod's scrape job is not present in prom config, please check ama-metrics-node config map for the presence of this job or the setting called
+
+    ```shell
+    kubectl get configmap ama-metrics-prometheus-config-node -n kube-system -oyaml
+    ```

+# Capture TSG
+
+Retina Capture create Kubernetes Jobs and translate the flags into the specification of the Pod. Locating the Pods by the Capture is essential to troubleshooting Retina Capture issues.
+
+## Find the Pod created for each Capture
+
+Run the following command to list captures:
+
+```shell
+kubectl retina capture list -n <capture namespace>
+```
+
+or get jobs through the capture name:
+
+```shell
+kubectl get job --selector  capture-name=<capture name> -n <capture namespace>
+```
+
+and then get the Pod through the job name by:
+
+```shell
+kubectl get pod -n <capture namespace> --seletor job-name=<capture job name>
+```
+
+## Capture Pod ImagePullBackOff
+
+By default, kubectl retina plugin will eventually create Capture Pods from the [MCR](https://mcr.microsoft.com/) image with the same version as the kubectl plugin. If the kubectl plugin is built from a local environment, the MCR image cannot be found. Check [capture CLI Debug Mode](../captures/cli.md#Debug_mode) for local development and testing.
+
+## Windows node allows only one capture job running at one time
+
+Retina Capture utilizes [`netsh`](https://learn.microsoft.com/en-us/windows-server/networking/technologies/netsh/netsh-contexts) to capture network traffic on Windows, and as only one netsh trace session is allowed on one Windows node, when a Windows node contains a pending or running Capture Pod, creating a Capture targeting the node will raise an error.
+To continue creating a capture on this windows node, you may delete the Capture per
+
+- List Capture Pods running on the Windows node
+
+```shell
+kubectl get pod -A -o wide |grep <Windows node name>
+```
+
+- Get Capture name from the Pod
+
+```shell
+kubectl describe pod <capture pod name> -n <capture pod namespace>  |grep capture-name| awk -F "=" '{print $2}' 
+```
+
+- Delete the Capture
+
+```shelll
+kubectl retina capture delete --namespace <capture pod namespace> --name <capture name>
+```
+
+## Network packets are not correctly captured
+
+In case you want to confirm how the network capture is performed, please check tcpdump.log/netsh.log in Capture bundle, or get the pod container log if the Capture is not deleted.
+The pcap file name includes UTC time, which records the network capture start time, which might also be helpful.

+4. Have a container registry setup and attach to the cluster (Create your own or login to an existing one)
+`az acr login --name <acr-name>`
+5. Additional flags for acr login if using an existing container registry: `--username <username> --password <password>`
+6. Attach credentials to your cluster/resource-group to the container registry
+`az aks update -n <cluster> -g <resource-group> --attach-acr <acr-name>`
+7. Build the docker image for retina `make retina-image`
+8. Push to container registry:
+`docker push <container-registry-url>/retina:<TAG>`
+9. Installing retina onto the cluster -

+ * Deduplicate BTF types and strings.
+ *
+ * BTF dedup algorithm takes as an input `struct btf` representing `.BTF` ELF
+ * section with all BTF type descriptors and string data. It overwrites that
+ * memory in-place with deduplicated types and strings without any loss of
+ * information. If optional `struct btf_ext` representing '.BTF.ext' ELF section
+ * is provided, all the strings referenced from .BTF.ext section are honored
+ * and updated to point to the right offsets after deduplication.
+ *
+ * If function returns with error, type/string data might be garbled and should
+ * be discarded.
+ *
+ * More verbose and detailed description of both problem btf_dedup is solving,
+ * as well as solution could be found at:
+ * https://facebookmicrosites.github.io/bpf/blog/2018/11/14/btf-enhancement.html
+ *
+ * Problem description and justification
+ * =====================================
+ *
+ * BTF type information is typically emitted either as a result of conversion
+ * from DWARF to BTF or directly by compiler. In both cases, each compilation
+ * unit contains information about a subset of all the types that are used
+ * in an application. These subsets are frequently overlapping and contain a lot
+ * of duplicated information when later concatenated together into a single
+ * binary. This algorithm ensures that each unique type is represented by single
+ * BTF type descriptor, greatly reducing resulting size of BTF data.
+ *
+ * Compilation unit isolation and subsequent duplication of data is not the only
+ * problem. The same type hierarchy (e.g., struct and all the type that struct
+ * references) in different compilation units can be represented in BTF to
+ * various degrees of completeness (or, rather, incompleteness) due to
+ * struct/union forward declarations.
+ *
+ * Let's take a look at an example, that we'll use to better understand the
+ * problem (and solution). Suppose we have two compilation units, each using
+ * same `struct S`, but each of them having incomplete type information about
+ * struct's fields:
+ *
+ * // CU #1:
+ * struct S;
+ * struct A {
+ *	int a;
+ *	struct A* self;
+ *	struct S* parent;
+ * };
+ * struct B;
+ * struct S {
+ *	struct A* a_ptr;
+ *	struct B* b_ptr;
+ * };
+ *
+ * // CU #2:
+ * struct S;
+ * struct A;
+ * struct B {
+ *	int b;
+ *	struct B* self;
+ *	struct S* parent;
+ * };
+ * struct S {
+ *	struct A* a_ptr;
+ *	struct B* b_ptr;
+ * };
+ *
+ * In case of CU #1, BTF data will know only that `struct B` exist (but no
+ * more), but will know the complete type information about `struct A`. While
+ * for CU #2, it will know full type information about `struct B`, but will
+ * only know about forward declaration of `struct A` (in BTF terms, it will
+ * have `BTF_KIND_FWD` type descriptor with name `B`).
+ *
+ * This compilation unit isolation means that it's possible that there is no
+ * single CU with complete type information describing structs `S`, `A`, and
+ * `B`. Also, we might get tons of duplicated and redundant type information.
+ *
+ * Additional complication we need to keep in mind comes from the fact that
+ * types, in general, can form graphs containing cycles, not just DAGs.
+ *
+ * While algorithm does deduplication, it also merges and resolves type
+ * information (unless disabled throught `struct btf_opts`), whenever possible.
+ * E.g., in the example above with two compilation units having partial type
+ * information for structs `A` and `B`, the output of algorithm will emit
+ * a single copy of each BTF type that describes structs `A`, `B`, and `S`
+ * (as well as type information for `int` and pointers), as if they were defined
+ * in a single compilation unit as:
+ *
+ * struct A {
+ *	int a;
+ *	struct A* self;
+ *	struct S* parent;
+ * };
+ * struct B {
+ *	int b;
+ *	struct B* self;
+ *	struct S* parent;
+ * };
+ * struct S {
+ *	struct A* a_ptr;
+ *	struct B* b_ptr;
+ * };
+ *
+ * Algorithm summary
+ * =================
+ *
+ * Algorithm completes its work in 6 separate passes:
+ *
+ * 1. Strings deduplication.
+ * 2. Primitive types deduplication (int, enum, fwd).
+ * 3. Struct/union types deduplication.
+ * 4. Reference types deduplication (pointers, typedefs, arrays, funcs, func
+ *    protos, and const/volatile/restrict modifiers).
+ * 5. Types compaction.
+ * 6. Types remapping.
+ *
+ * Algorithm determines canonical type descriptor, which is a single
+ * representative type for each truly unique type. This canonical type is the
+ * one that will go into final deduplicated BTF type information. For
+ * struct/unions, it is also the type that algorithm will merge additional type
+ * information into (while resolving FWDs), as it discovers it from data in
+ * other CUs. Each input BTF type eventually gets either mapped to itself, if
+ * that type is canonical, or to some other type, if that type is equivalent
+ * and was chosen as canonical representative. This mapping is stored in
+ * `btf_dedup->map` array. This map is also used to record STRUCT/UNION that
+ * FWD type got resolved to.
+ *
+ * To facilitate fast discovery of canonical types, we also maintain canonical
+ * index (`btf_dedup->dedup_table`), which maps type descriptor's signature hash
+ * (i.e., hashed kind, name, size, fields, etc) into a list of canonical types
+ * that match that signature. With sufficiently good choice of type signature
+ * hashing function, we can limit number of canonical types for each unique type
+ * signature to a very small number, allowing to find canonical type for any
+ * duplicated type very quickly.
+ *
+ * Struct/union deduplication is the most critical part and algorithm for
+ * deduplicating structs/unions is described in greater details in comments for
+ * `btf_dedup_is_equiv` function.

+ * here, though keep in mind that not all types in canonical graph are
+ * necessarily canonical representatives themselves, some of them might be
+ * duplicates or its uniqueness might not have been established yet).
+ * Returns:
+ *  - >0, if type graphs are equivalent;
+ *  -  0, if not equivalent;
+ *  - <0, on error.
+ *
+ * Algorithm performs side-by-side DFS traversal of both type graphs and checks
+ * equivalence of BTF types at each step. If at any point BTF types in candidate
+ * and canonical graphs are not compatible structurally, whole graphs are
+ * incompatible. If types are structurally equivalent (i.e., all information
+ * except referenced type IDs is exactly the same), a mapping from `canon_id` to
+ * a `cand_id` is recored in hypothetical mapping (`btf_dedup->hypot_map`).
+ * If a type references other types, then those referenced types are checked
+ * for equivalence recursively.
+ *
+ * During DFS traversal, if we find that for current `canon_id` type we
+ * already have some mapping in hypothetical map, we check for two possible
+ * situations:
+ *   - `canon_id` is mapped to exactly the same type as `cand_id`. This will
+ *     happen when type graphs have cycles. In this case we assume those two
+ *     types are equivalent.
+ *   - `canon_id` is mapped to different type. This is contradiction in our
+ *     hypothetical mapping, because same graph in canonical graph corresponds
+ *     to two different types in candidate graph, which for equivalent type
+ *     graphs shouldn't happen. This condition terminates equivalence check
+ *     with negative result.
+ *
+ * If type graphs traversal exhausts types to check and find no contradiction,
+ * then type graphs are equivalent.
+ *
+ * When checking types for equivalence, there is one special case: FWD types.
+ * If FWD type resolution is allowed and one of the types (either from canonical
+ * or candidate graph) is FWD and other is STRUCT/UNION (depending on FWD's kind
+ * flag) and their names match, hypothetical mapping is updated to point from
+ * FWD to STRUCT/UNION. If graphs will be determined as equivalent successfully,
+ * this mapping will be used to record FWD -> STRUCT/UNION mapping permanently.
+ *
+ * Technically, this could lead to incorrect FWD to STRUCT/UNION resolution,
+ * if there are two exactly named (or anonymous) structs/unions that are
+ * compatible structurally, one of which has FWD field, while other is concrete
+ * STRUCT/UNION, but according to C sources they are different structs/unions
+ * that are referencing different types with the same name. This is extremely
+ * unlikely to happen, but btf_dedup API allows to disable FWD resolution if
+ * this logic is causing problems.
+ *
+ * Doing FWD resolution means that both candidate and/or canonical graphs can
+ * consists of portions of the graph that come from multiple compilation units.
+ * This is due to the fact that types within single compilation unit are always
+ * deduplicated and FWDs are already resolved, if referenced struct/union
+ * definiton is available. So, if we had unresolved FWD and found corresponding
+ * STRUCT/UNION, they will be from different compilation units. This
+ * consequently means that when we "link" FWD to corresponding STRUCT/UNION,
+ * type graph will likely have at least two different BTF types that describe
+ * same type (e.g., most probably there will be two different BTF types for the
+ * same 'int' primitive type) and could even have "overlapping" parts of type
+ * graph that describe same subset of types.
+ *
+ * This in turn means that our assumption that each type in canonical graph
+ * must correspond to exactly one type in candidate graph might not hold
+ * anymore and will make it harder to detect contradictions using hypothetical
+ * map. To handle this problem, we allow to follow FWD -> STRUCT/UNION
+ * resolution only in canonical graph. FWDs in candidate graphs are never
+ * resolved. To see why it's OK, let's check all possible situations w.r.t. FWDs
+ * that can occur:
+ *   - Both types in canonical and candidate graphs are FWDs. If they are
+ *     structurally equivalent, then they can either be both resolved to the
+ *     same STRUCT/UNION or not resolved at all. In both cases they are
+ *     equivalent and there is no need to resolve FWD on candidate side.
+ *   - Both types in canonical and candidate graphs are concrete STRUCT/UNION,
+ *     so nothing to resolve as well, algorithm will check equivalence anyway.
+ *   - Type in canonical graph is FWD, while type in candidate is concrete
+ *     STRUCT/UNION. In this case candidate graph comes from single compilation
+ *     unit, so there is exactly one BTF type for each unique C type. After
+ *     resolving FWD into STRUCT/UNION, there might be more than one BTF type
+ *     in canonical graph mapping to single BTF type in candidate graph, but
+ *     because hypothetical mapping maps from canonical to candidate types, it's
+ *     alright, and we still maintain the property of having single `canon_id`
+ *     mapping to single `cand_id` (there could be two different `canon_id`
+ *     mapped to the same `cand_id`, but it's not contradictory).
+ *   - Type in canonical graph is concrete STRUCT/UNION, while type in candidate
+ *     graph is FWD. In this case we are just going to check compatibility of
+ *     STRUCT/UNION and corresponding FWD, and if they are compatible, we'll
+ *     assume that whatever STRUCT/UNION FWD resolves to must be equivalent to
+ *     a concrete STRUCT/UNION from canonical graph. If the rest of type graphs
+ *     turn out equivalent, we'll re-resolve FWD to concrete STRUCT/UNION from
+ *     canonical graph.

+ * doesn't work here because both variants have 4 input arguments.
+ *
+ * (void *) casts are necessary to avoid compilation warnings about type
+ * mismatches, because even though __builtin_choose_expr() only ever evaluates
+ * one side the other side still has to satisfy type constraints (this is
+ * compiler implementation limitation which might be lifted eventually,
+ * according to the documentation). So passing struct btf_ext in place of
+ * btf_dump_printf_fn_t would be generating compilation warning.  Casting to
+ * void * avoids this issue.
+ *
+ * Also, two type compatibility checks for a function and function pointer are
+ * required because passing function reference into btf_dump__new() as
+ * btf_dump__new(..., my_callback, ...) and as btf_dump__new(...,
+ * &my_callback, ...) (not explicit ampersand in the latter case) actually
+ * differs as far as __builtin_types_compatible_p() is concerned. Thus two
+ * checks are combined to detect callback argument.
+ *
+ * The rest works just like in case of ___libbpf_override() usage with symbol
+ * versioning.
+ *
+ * C++ compilers don't support __builtin_types_compatible_p(), so at least
+ * don't screw up compilation for them and let C++ users pick btf_dump__new
+ * vs btf_dump__new_deprecated explicitly.

+ * Determine order of emitting dependent types and specified type to satisfy
+ * C compilation rules.  This is done through topological sorting with an
+ * additional complication which comes from C rules. The main idea for C is
+ * that if some type is "embedded" into a struct/union, it's size needs to be
+ * known at the time of definition of containing type. E.g., for:
+ *
+ *	struct A {};
+ *	struct B { struct A x; }
+ *
+ * struct A *HAS* to be defined before struct B, because it's "embedded",
+ * i.e., it is part of struct B layout. But in the following case:
+ *
+ *	struct A;
+ *	struct B { struct A *x; }
+ *	struct A {};
+ *
+ * it's enough to just have a forward declaration of struct A at the time of
+ * struct B definition, as struct B has a pointer to struct A, so the size of
+ * field x is known without knowing struct A size: it's sizeof(void *).
+ *
+ * Unfortunately, there are some trickier cases we need to handle, e.g.:
+ *
+ *	struct A {}; // if this was forward-declaration: compilation error
+ *	struct B {
+ *		struct { // anonymous struct
+ *			struct A y;
+ *		} *x;
+ *	};
+ *
+ * In this case, struct B's field x is a pointer, so it's size is known
+ * regardless of the size of (anonymous) struct it points to. But because this
+ * struct is anonymous and thus defined inline inside struct B, *and* it
+ * embeds struct A, compiler requires full definition of struct A to be known
+ * before struct B can be defined. This creates a transitive dependency
+ * between struct A and struct B. If struct A was forward-declared before
+ * struct B definition and fully defined after struct B definition, that would
+ * trigger compilation error.
+ *
+ * All this means that while we are doing topological sorting on BTF type
+ * graph, we need to determine relationships between different types (graph
+ * nodes):
+ *   - weak link (relationship) between X and Y, if Y *CAN* be
+ *   forward-declared at the point of X definition;
+ *   - strong link, if Y *HAS* to be fully-defined before X can be defined.
+ *
+ * The rule is as follows. Given a chain of BTF types from X to Y, if there is
+ * BTF_KIND_PTR type in the chain and at least one non-anonymous type
+ * Z (excluding X, including Y), then link is weak. Otherwise, it's strong.
+ * Weak/strong relationship is determined recursively during DFS traversal and
+ * is returned as a result from btf_dump_order_type().
+ *
+ * btf_dump_order_type() is trying to avoid unnecessary forward declarations,
+ * but it is not guaranteeing that no extraneous forward declarations will be
+ * emitted.
+ *
+ * To avoid extra work, algorithm marks some of BTF types as ORDERED, when
+ * it's done with them, but not for all (e.g., VOLATILE, CONST, RESTRICT,
+ * ARRAY, FUNC_PROTO), as weak/strong semantics for those depends on the
+ * entire graph path, so depending where from one came to that BTF type, it
+ * might cause weak or strong ordering. For types like STRUCT/UNION/INT/ENUM,
+ * once they are processed, there is no need to do it again, so they are
+ * marked as ORDERED. We can mark PTR as ORDERED as well, as it semi-forces
+ * weak link, unless subsequent referenced STRUCT/UNION/ENUM is anonymous. But
+ * in any case, once those are processed, no need to do it again, as the
+ * result won't change.
+ *
+ * Returns:
+ *   - 1, if type is part of strong link (so there is strong topological
+ *   ordering requirements);
+ *   - 0, if type is part of weak link (so can be satisfied through forward
+ *   declaration);
+ *   - <0, on error (e.g., unsatisfiable type loop detected).

+ * Emit type declaration (e.g., field type declaration in a struct or argument

+ * cases worth mentioning:
+ *   - function prototypes (especially nesting of function prototypes);
+ *   - arrays;
+ *   - const/volatile/restrict for pointers vs other types.
+ *
+ * For a good discussion of *PARSING* C syntax (as a human), see
+ * Peter van der Linden's "Expert C Programming: Deep C Secrets",
+ * Ch.3 "Unscrambling Declarations in C".
+ *
+ * It won't help with BTF to C conversion much, though, as it's an opposite
+ * problem. So we came up with this algorithm in reverse to van der Linden's
+ * parsing algorithm. It goes from structured BTF representation of type
+ * declaration to a valid compilable C syntax.
+ *
+ * For instance, consider this C typedef:
+ *	typedef const int * const * arr[10] arr_t;
+ * It will be represented in BTF with this chain of BTF types:
+ *	[typedef] -> [array] -> [ptr] -> [const] -> [ptr] -> [const] -> [int]
+ *
+ * Notice how [const] modifier always goes before type it modifies in BTF type
+ * graph, but in C syntax, const/volatile/restrict modifiers are written to
+ * the right of pointers, but to the left of other types. There are also other
+ * quirks, like function pointers, arrays of them, functions returning other
+ * functions, etc.
+ *
+ * We handle that by pushing all the types to a stack, until we hit "terminal"
+ * type (int/enum/struct/union/fwd). Then depending on the kind of a type on
+ * top of a stack, modifiers are handled differently. Array/function pointers
+ * have also wildly different syntax and how nesting of them are done. See
+ * code for authoritative definition.
+ *
+ * To avoid allocating new stack for each independent chain of BTF types, we
+ * share one bigger stack, with each chain working only on its own local view
+ * of a stack frame. Some care is required to "pop" stack frames after
+ * processing type declaration chain.

+	 * maps of a different BPF object.
+	 * As an example, let's say we have bpf_object named 'my_object_name'
+	 * and internal map corresponding to '.rodata' ELF section. The final
+	 * map name advertised to user and to the kernel will be
+	 * 'my_objec.rodata', taking first 8 characters of object name and
+	 * entire 7 characters of '.rodata'.
+	 * Somewhat confusingly, if internal map ELF section name is shorter
+	 * than 7 characters, e.g., '.bss', we still reserve 7 characters
+	 * for the suffix, even though we only have 4 actual characters, and
+	 * resulting map will be called 'my_objec.bss', not even using all 15
+	 * characters allowed by the kernel. Oh well, at least the truncated
+	 * object name is somewhat consistent in this case. But if the map
+	 * name is '.kconfig', we'll still have entirety of '.kconfig' added
+	 * (8 chars) and thus will be left with only first 7 characters of the
+	 * object name ('my_obje'). Happy guessing, user, that the final map
+	 * name will be "my_obje.kconfig".
+	 * Now, with libbpf starting to support arbitrarily named .rodata.*
+	 * and .data.* data sections, it's possible that ELF section name is
+	 * longer than allowed 15 chars, so we now need to be careful to take
+	 * only up to 15 first characters of ELF name, taking no BPF object
+	 * name characters at all. So '.rodata.abracadabra' will result in
+	 * '.rodata.abracad' kernel and user-visible name.
+	 * We need to keep this convoluted logic intact for .data, .bss and
+	 * .rodata maps, but for new custom .data.custom and .rodata.custom
+	 * maps we use their ELF names as is, not prepending bpf_object name
+	 * in front. We still need to truncate them to 15 characters for the
+	 * kernel. Full name can be recovered for such maps by using DATASEC
+	 * BTF type associated with such map's value type, though.

+ * Relocate sub-program calls.
+ *
+ * Algorithm operates as follows. Each entry-point BPF program (referred to as
+ * main prog) is processed separately. For each subprog (non-entry functions,
+ * that can be called from either entry progs or other subprogs) gets their
+ * sub_insn_off reset to zero. This serves as indicator that this subprogram
+ * hasn't been yet appended and relocated within current main prog. Once its
+ * relocated, sub_insn_off will point at the position within current main prog
+ * where given subprog was appended. This will further be used to relocate all
+ * the call instructions jumping into this subprog.
+ *
+ * We start with main program and process all call instructions. If the call
+ * is into a subprog that hasn't been processed (i.e., subprog->sub_insn_off
+ * is zero), subprog instructions are appended at the end of main program's
+ * instruction array. Then main program is "put on hold" while we recursively
+ * process newly appended subprogram. If that subprogram calls into another
+ * subprogram that hasn't been appended, new subprogram is appended again to
+ * the *main* prog's instructions (subprog's instructions are always left
+ * untouched, as they need to be in unmodified state for subsequent main progs
+ * and subprog instructions are always sent only as part of a main prog) and
+ * the process continues recursively. Once all the subprogs called from a main
+ * prog or any of its subprogs are appended (and relocated), all their
+ * positions within finalized instructions array are known, so it's easy to
+ * rewrite call instructions with correct relative offsets, corresponding to
+ * desired target subprog.
+ *
+ * Its important to realize that some subprogs might not be called from some
+ * main prog and any of its called/used subprogs. Those will keep their
+ * subprog->sub_insn_off as zero at all times and won't be appended to current
+ * main prog and won't be relocated within the context of current main prog.
+ * They might still be used from other main progs later.
+ *
+ * Visually this process can be shown as below. Suppose we have two main
+ * programs mainA and mainB and BPF object contains three subprogs: subA,
+ * subB, and subC. mainA calls only subA, mainB calls only subC, but subA and
+ * subC both call subB:
+ *
+ *        +--------+ +-------+
+ *        |        v v       |
+ *     +--+---+ +--+-+-+ +---+--+
+ *     | subA | | subB | | subC |
+ *     +--+---+ +------+ +---+--+
+ *        ^                  ^
+ *        |                  |
+ *    +---+-------+   +------+----+
+ *    |   mainA   |   |   mainB   |
+ *    +-----------+   +-----------+
+ *
+ * We'll start relocating mainA, will find subA, append it and start
+ * processing sub A recursively:
+ *
+ *    +-----------+------+
+ *    |   mainA   | subA |
+ *    +-----------+------+
+ *
+ * At this point we notice that subB is used from subA, so we append it and
+ * relocate (there are no further subcalls from subB):
+ *
+ *    +-----------+------+------+
+ *    |   mainA   | subA | subB |
+ *    +-----------+------+------+
+ *
+ * At this point, we relocate subA calls, then go one level up and finish with
+ * relocatin mainA calls. mainA is done.
+ *
+ * For mainB process is similar but results in different order. We start with
+ * mainB and skip subA and subB, as mainB never calls them (at least
+ * directly), but we see subC is needed, so we append and start processing it:
+ *
+ *    +-----------+------+
+ *    |   mainB   | subC |
+ *    +-----------+------+
+ * Now we see subC needs subB, so we go back to it, append and relocate it:
+ *
+ *    +-----------+------+------+
+ *    |   mainB   | subC | subB |
+ *    +-----------+------+------+
+ *
+ * At this point we unwind recursion, relocate calls in subC, then in mainB.

+ * Many libbpf API functions which return pointers have logic to encode error

+ * should be used on the return value from these functions immediately after
+ * calling the API function, with no intervening calls that could clobber the

+ * For these API functions, if `libbpf_set_strict_mode(LIBBPF_STRICT_CLEAN_PTRS)`
+ * is enabled, NULL is returned on error instead.
+ *
+ * If ptr is NULL, then errno should be already set by the failing
+ * API, because libbpf never returns NULL on success and it now always
+ * sets errno on error.
+ *
+ * Example usage:
+ *
+ *   struct perf_buffer *pb;
+ *
+ *   pb = perf_buffer__new(bpf_map__fd(obj->maps.events), PERF_BUFFER_PAGES, &opts);

+ * Calculate CO-RE relocation target result.
+ *
+ * The outline and important points of the algorithm:
+ * 1. For given local type, find corresponding candidate target types.
+ *    Candidate type is a type with the same "essential" name, ignoring
+ *    everything after last triple underscore (___). E.g., `sample`,
+ *    `sample___flavor_one`, `sample___flavor_another_one`, are all candidates
+ *    for each other. Names with triple underscore are referred to as
+ *    "flavors" and are useful, among other things, to allow to
+ *    specify/support incompatible variations of the same kernel struct, which
+ *    might differ between different kernel versions and/or build
+ *    configurations.
+ *
+ *    N.B. Struct "flavors" could be generated by bpftool's BTF-to-C
+ *    converter, when deduplicated BTF of a kernel still contains more than
+ *    one different types with the same name. In that case, ___2, ___3, etc
+ *    are appended starting from second name conflict. But start flavors are
+ *    also useful to be defined "locally", in BPF program, to extract same
+ *    data from incompatible changes between different kernel
+ *    versions/configurations. For instance, to handle field renames between
+ *    kernel versions, one can use two flavors of the struct name with the
+ *    same common name and use conditional relocations to extract that field,
+ *    depending on target kernel version.
+ * 2. For each candidate type, try to match local specification to this
+ *    candidate target type. Matching involves finding corresponding
+ *    high-level spec accessors, meaning that all named fields should match,
+ *    as well as all array accesses should be within the actual bounds. Also,
+ *    types should be compatible (see bpf_core_fields_are_compat for details).
+ * 3. It is supported and expected that there might be multiple flavors
+ *    matching the spec. As long as all the specs resolve to the same set of
+ *    offsets across all candidates, there is no error. If there is any
+ *    ambiguity, CO-RE relocation will fail. This is necessary to accomodate
+ *    imprefection of BTF deduplication, which can cause slight duplication of
+ *    the same BTF type, if some directly or indirectly referenced (by
+ *    pointer) type gets resolved to different actual types in different
+ *    object files. If such situation occurs, deduplicated BTF will end up
+ *    with two (or more) structurally identical types, which differ only in
+ *    types they refer to through pointer. This should be OK in most cases and
+ *    is not an error.
+ * 4. Candidate types search is performed by linearly scanning through all
+ *    types in target BTF. It is anticipated that this is overall more
+ *    efficient memory-wise and not significantly worse (if not better)
+ *    CPU-wise compared to prebuilding a map from all local type names to
+ *    a list of candidate type names. It's also sped up by caching resolved
+ *    list of matching candidates per each local "root" type ID, that has at
+ *    least one bpf_core_relo associated with it. This list is shared
+ *    between multiple relocations for the same type ID and is updated as some
+ *    of the candidates are pruned due to structural incompatibility.

+/* libbpf's USDT support consists of BPF-side state/code and user-space
+ * state/code working together in concert. BPF-side parts are defined in
+ * usdt.bpf.h header library. User-space state is encapsulated by struct
+ * usdt_manager and all the supporting code centered around usdt_manager.
+ *
+ * usdt.bpf.h defines two BPF maps that usdt_manager expects: USDT spec map
+ * and IP-to-spec-ID map, which is auxiliary map necessary for kernels that
+ * don't support BPF cookie (see below). These two maps are implicitly
+ * embedded into user's end BPF object file when user's code included
+ * usdt.bpf.h. This means that libbpf doesn't do anything special to create
+ * these USDT support maps. They are created by normal libbpf logic of
+ * instantiating BPF maps when opening and loading BPF object.
+ *
+ * As such, libbpf is basically unaware of the need to do anything
+ * USDT-related until the very first call to bpf_program__attach_usdt(), which
+ * can be called by user explicitly or happen automatically during skeleton
+ * attach (or, equivalently, through generic bpf_program__attach() call). At
+ * this point, libbpf will instantiate and initialize struct usdt_manager and
+ * store it in bpf_object. USDT manager is per-BPF object construct, as each
+ * independent BPF object might or might not have USDT programs, and thus all
+ * the expected USDT-related state. There is no coordination between two
+ * bpf_object in parts of USDT attachment, they are oblivious of each other's
+ * existence and libbpf is just oblivious, dealing with bpf_object-specific
+ * USDT state.
+ *
+ * Quick crash course on USDTs.
+ *
+ * From user-space application's point of view, USDT is essentially just
+ * a slightly special function call that normally has zero overhead, unless it
+ * is being traced by some external entity (e.g, BPF-based tool). Here's how
+ * a typical application can trigger USDT probe:
+ *
+ * #include <sys/sdt.h>  // provided by systemtap-sdt-devel package
+ * // folly also provide similar functionality in folly/tracing/StaticTracepoint.h
+ *
+ * STAP_PROBE3(my_usdt_provider, my_usdt_probe_name, 123, x, &y);
+ *
+ * USDT is identified by it's <provider-name>:<probe-name> pair of names. Each
+ * individual USDT has a fixed number of arguments (3 in the above example)
+ * and specifies values of each argument as if it was a function call.
+ *
+ * USDT call is actually not a function call, but is instead replaced by
+ * a single NOP instruction (thus zero overhead, effectively). But in addition
+ * to that, those USDT macros generate special SHT_NOTE ELF records in
+ * .note.stapsdt ELF section. Here's an example USDT definition as emitted by
+ * `readelf -n <binary>`:
+ *
+ *   stapsdt              0x00000089       NT_STAPSDT (SystemTap probe descriptors)
+ *   Provider: test
+ *   Name: usdt12
+ *   Location: 0x0000000000549df3, Base: 0x00000000008effa4, Semaphore: 0x0000000000a4606e
+ *   Arguments: -4@-1204(%rbp) -4@%edi -8@-1216(%rbp) -8@%r8 -4@$5 -8@%r9 8@%rdx 8@%r10 -4@$-9 -2@%cx -2@%ax -1@%sil
+ *
+ * In this case we have USDT test:usdt12 with 12 arguments.
+ *
+ * Location and base are offsets used to calculate absolute IP address of that
+ * NOP instruction that kernel can replace with an interrupt instruction to
+ * trigger instrumentation code (BPF program for all that we care about).
+ *
+ * Semaphore above is and optional feature. It records an address of a 2-byte
+ * refcount variable (normally in '.probes' ELF section) used for signaling if
+ * there is anything that is attached to USDT. This is useful for user
+ * applications if, for example, they need to prepare some arguments that are
+ * passed only to USDTs and preparation is expensive. By checking if USDT is
+ * "activated", an application can avoid paying those costs unnecessarily.
+ * Recent enough kernel has built-in support for automatically managing this
+ * refcount, which libbpf expects and relies on. If USDT is defined without
+ * associated semaphore, this value will be zero. See selftests for semaphore
+ * examples.
+ *
+ * Arguments is the most interesting part. This USDT specification string is
+ * providing information about all the USDT arguments and their locations. The
+ * part before @ sign defined byte size of the argument (1, 2, 4, or 8) and
+ * whether the argument is signed or unsigned (negative size means signed).
+ * The part after @ sign is assembly-like definition of argument location
+ * (see [0] for more details). Technically, assembler can provide some pretty
+ * advanced definitions, but libbpf is currently supporting three most common
+ * cases:
+ *   1) immediate constant, see 5th and 9th args above (-4@$5 and -4@-9);
+ *   2) register value, e.g., 8@%rdx, which means "unsigned 8-byte integer
+ *      whose value is in register %rdx";
+ *   3) memory dereference addressed by register, e.g., -4@-1204(%rbp), which
+ *      specifies signed 32-bit integer stored at offset -1204 bytes from
+ *      memory address stored in %rbp.
+ *
+ *   [0] https://sourceware.org/systemtap/wiki/UserSpaceProbeImplementation
+ *
+ * During attachment, libbpf parses all the relevant USDT specifications and
+ * prepares `struct usdt_spec` (USDT spec), which is then provided to BPF-side
+ * code through spec map. This allows BPF applications to quickly fetch the
+ * actual value at runtime using a simple BPF-side code.
+ *
+ * With basics out of the way, let's go over less immediately obvious aspects
+ * of supporting USDTs.
+ *
+ * First, there is no special USDT BPF program type. It is actually just
+ * a uprobe BPF program (which for kernel, at least currently, is just a kprobe
+ * program, so BPF_PROG_TYPE_KPROBE program type). With the only difference
+ * that uprobe is usually attached at the function entry, while USDT will
+ * normally will be somewhere inside the function. But it should always be
+ * pointing to NOP instruction, which makes such uprobes the fastest uprobe
+ * kind.
+ *
+ * Second, it's important to realize that such STAP_PROBEn(provider, name, ...)
+ * macro invocations can end up being inlined many-many times, depending on
+ * specifics of each individual user application. So single conceptual USDT
+ * (identified by provider:name pair of identifiers) is, generally speaking,
+ * multiple uprobe locations (USDT call sites) in different places in user
+ * application. Further, again due to inlining, each USDT call site might end
+ * up having the same argument #N be located in a different place. In one call
+ * site it could be a constant, in another will end up in a register, and in
+ * yet another could be some other register or even somewhere on the stack.
+ *
+ * As such, "attaching to USDT" means (in general case) attaching the same
+ * uprobe BPF program to multiple target locations in user application, each
+ * potentially having a completely different USDT spec associated with it.
+ * To wire all this up together libbpf allocates a unique integer spec ID for
+ * each unique USDT spec. Spec IDs are allocated as sequential small integers
+ * so that they can be used as keys in array BPF map (for performance reasons).
+ * Spec ID allocation and accounting is big part of what usdt_manager is
+ * about. This state has to be maintained per-BPF object and coordinate
+ * between different USDT attachments within the same BPF object.
+ *
+ * Spec ID is the key in spec BPF map, value is the actual USDT spec layed out
+ * as struct usdt_spec. Each invocation of BPF program at runtime needs to
+ * know its associated spec ID. It gets it either through BPF cookie, which
+ * libbpf sets to spec ID during attach time, or, if kernel is too old to
+ * support BPF cookie, through IP-to-spec-ID map that libbpf maintains in such
+ * case. The latter means that some modes of operation can't be supported
+ * without BPF cookie. Such mode is attaching to shared library "generically",
+ * without specifying target process. In such case, it's impossible to
+ * calculate absolute IP addresses for IP-to-spec-ID map, and thus such mode
+ * is not supported without BPF cookie support.
+ *
+ * Note that libbpf is using BPF cookie functionality for its own internal
+ * needs, so user itself can't rely on BPF cookie feature. To that end, libbpf
+ * provides conceptually equivalent USDT cookie support. It's still u64
+ * user-provided value that can be associated with USDT attachment. Note that
+ * this will be the same value for all USDT call sites within the same single
+ * *logical* USDT attachment. This makes sense because to user attaching to
+ * USDT is a single BPF program triggered for singular USDT probe. The fact
+ * that this is done at multiple actual locations is a mostly hidden
+ * implementation details. This USDT cookie value can be fetched with
+ * bpf_usdt_cookie(ctx) API provided by usdt.bpf.h
+ *
+ * Lastly, while single USDT can have tons of USDT call sites, it doesn't
+ * necessarily have that many different USDT specs. It very well might be
+ * that 1000 USDT call sites only need 5 different USDT specs, because all the
+ * arguments are typically contained in a small set of registers or stack
+ * locations. As such, it's wasteful to allocate as many USDT spec IDs as
+ * there are USDT call sites. So libbpf tries to be frugal and performs
+ * on-the-fly deduplication during a single USDT attachment to only allocate
+ * the minimal required amount of unique USDT specs (and thus spec IDs). This
+ * is trivially achieved by using USDT spec string (Arguments string from USDT
+ * note) as a lookup key in a hashmap. USDT spec string uniquely defines
+ * everything about how to fetch USDT arguments, so two USDT call sites
+ * sharing USDT spec string can safely share the same USDT spec and spec ID.
+ * Note, this spec string deduplication is happening only during the same USDT
+ * attachment, so each USDT spec shares the same USDT cookie value. This is
+ * not generally true for other USDT attachments within the same BPF object,
+ * as even if USDT spec string is the same, USDT cookie value can be
+ * different. It was deemed excessive to try to deduplicate across independent
+ * USDT attachments by taking into account USDT spec string *and* USDT cookie
+ * value, which would complicated spec ID accounting significantly for little
+ * gain.

+# Overview
+
+We use GITHUB_TOKEN to get the following:
+
+1. Workflow ID with the retina test yaml
+2. Get the latest main branch successful workflow run with that id
+3. Get the artifacts from that run and download them
+
+## Testing Locally
+
+1. Set your PAT from github developer settings as `GITHUB_TOKEN` env variable
+https: //docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token#creating-a-personal-access-token-classic
+2. Set a test PR number as `PULL_REQUEST_NUMBER` env variable
+3. generate coverage.out for local branch with `go test -coverprofile=coverage.out ./...`
+4. run `make retina-cc` on your local branch and not main.

+# Website
+
+This website is built using [Docusaurus 2](https://docusaurus.io/), a modern static website generator.
+
+## Development
+
+When adding a new doc, make sure to add it to /site/sidebars.js
+
+To test, run `make docs` to spin up local webserver and view changes with hot reload
+
+## Using Yarn
+
+### Installation
+
+Install `yarn` (e.g. for Ubuntu, try [this guide](https://www.linuxcapable.com/how-to-install-yarn-on-ubuntu-linux/#install-yarn-on-ubuntu-2204-or-2004-via-nodesource)).
+
+In this directory (*retina/site/*), run:
+```bash
+yarn
+```
+
+### Local Development
+
+```bash
+yarn start
+```
+
+This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
+
+### Build
+
+```bash
+yarn build
+```
+
+This command generates static content into the `build` directory and can be served using any static contents hosting service.
+
+## Deployment
+
+Using SSH:
+
+```bash
+USE_SSH=true yarn deploy
+```
+
+Not using SSH:
+
+```bash
+GIT_USER=<Your GitHub username> yarn deploy
+```
+
+If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the `gh-pages` branch.

+# Integration Tests
+
+## Framework + Structure
+
+We are using ginkgo to run and test retina for our integration tests. The MAKEFILE provide commands to run these tests and create test images. These integration tests will run on an AKS cluster which can be found here
+`Retina/scripts/create_aks_cluster.sh`
+When testing for advanced metrics, we should check if enablePodLevel is set. For an example, we can look at ./plugins/dropreson/dropreason_suite_test.go. This checks for the environment variable set before adding a new test entry for advanced metrics.
+
+The azure pipeline was updated to accomdate these changes. The pipeline will create cluster for each profile, install retina with ENABLE_POD_LEVEL=true when the profile is "adv", and then it will run the integration tests.
+
+/capture - integration tests related to capture command
+/common - common tools we will use for our integration tests
+/fixtures - these are static files which will be used for integration tests, such as crd configuraitons
+/plugins - these are integration tests related to our ebpf programs
+
+[This is the PR which has the integration test changes and pipeline changes](https://github.com/microsoft/retina/pull/)562/files
+
+## Expectations
+
+Each suite should:
+
+* be idempotent
+* not change cluster state (like delete retina-agent)
+* no interference with other tests

+# Retina Scale Testing
+
+* example-*.yaml files are used to generate resources for the cluster using `./generate-yamls.sh`. This generates cluster role bindings, deployments, network polcies, and service accounts.
+
+* `create-all.sh` will create all the resources for the cluster.
+
+* `cpu-and-mem.sh` is the script used to track the cpu and mem of retina pods, and node metrics and output the results as a csv in `./results/`.
+
+* `pprof.sh` will get the pprof for retina agents which have mem > 100 Mb and will output the results in `./results/$pod`.
+
+* `restarts.sh` will get the previous logs for retina agents which have restarted and will output the results in `./results`.
+
+* `scrape-metrics.sh` is currently not used, but can be used/modified to go through each retina pod and get logs or metrics.
+
+* `az aks nodepool scale --name <node-pool> --cluster-name <cluster-name> --resource-group <resource-group-name> --node-count 1000` was used to scale to 1k nodes for testing.
