`conf.xml` file in the `app/src/main/res/values/` folder, similar to the one shown below: + +```xml + + + + +``` + +This build-time configuration is applied **only once, at first startup of the app**, as the main use case for this is first-time configuration for newly provisioned devices. +Modifying it afterwards (for example, via an update containing a new version of the RDFM app) will not result in the change of existing configuration. + +### Runtime app configuration + +It is possible to change the app's configuration at runtime by simply starting the RDFM app from the drawer and selecting `Settings` from the context menu. + +### Configuration options + +The following configuration options are available: +- RDFM server URL (`http`/`https` scheme) +- Update check interval (in seconds) +- Maximum amount of concurrent shell sessions (set to `0` to disable reverse shell functionality) + +## Available intents + +### Update check intent + +This intent allows an external app to force

intent and set extra values on the intent to the settings you wish to change. +For example, to set the server address: +```java +Intent configIntent = new Intent("com.antmicro.update.rdfm.configurationSet"); +configIntent.putExtra("ota_server_address", "http://CUSTOM-OTA-ADDRESS/"); +mContext.sendBroadcast(configIntent); +``` + +The supported configuration key names can be found in the `res/values/strings.xml` file with the `preference_` prefix. + +Aside from setting the configuration, you can also fetch the current configuration of the app: +```java +Intent configIntent = new Intent("com.antmicro.update.rdfm.configurationGet"); +mContext.sendBroadcast(configIntent); + +// Now listen for

Zephyr application + +#### Building the image + +To allow your application to be used with MCUmgr client, you will have to enable Zephyr's [device management subsystem](https://docs.zephyrproject.org/latest/services/device_mgmt/index.html#device-mgmt). +For the client to function properly, both [*image management*](https://docs.zephyrproject.org/latest/services/device_mgmt/smp_groups/smp_group_1.html) +and [*OS management*](https://docs.zephyrproject.org/latest/services/device_mgmt/smp_groups/smp_group_0.html) groups need to be enabled. +You will also have to enable and configure [SMP transport](https://docs.zephyrproject.org/latest/services/device_mgmt/smp_transport.html) +(either serial, BLE or udp) that you wish to use. +To learn how to do that, you can reference Zephyr's [`smp_svr` sample](https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/subsys/mgmt/mcumgr/smp_svr) +which provides configuration for all of them. + +You will also have set `MCUBOOT_BOOTLOADER_MODE` setting to match the *swapping algorithm* you've configured for the [bootloader](#building-the-bootloader): + +:::{table} +:name: Swap algorithm configuration options + +MCUboot | Zephyr +--- | --- +`BOOT_SWAP_USING_MOVE` | `MCUBOOT_BOOTLOADER_MODE_SWAP_WITHOUT_SCRATCH` +`BOOT_SWAP_USING_SCRATCH` | `MCUBOOT_BOOTLOADER_MODE_SWAP_SCRATCH` +::: + +:::{important} +####

documentation](https://docs.zephyrproject.org/latest/samples/subsys/mgmt/mcumgr/smp_svr/README.html#smp-svr). + +#### Signing the image + +By default MCUboot will only accept images that are properly signed with the same key as the bootloader itself. +Only `BIN` and `HEX` output types can be signed. +The recommended way for managing signing keys is using [MCUboot's image tool](#generating-image-signing-key), +which is shipped together with Zephyr's MCUboot implementation. +When signing an image, you also have to provide an image version, that's embedded in the signed image header. +This is also the value that will be reported by the MCUmgr client as the current running software version back to the [RDFM server](./rdfm_mgmt_server.md). +Image version is specified in `major.minor.revision+build` format. + +##### Automatically + +Zephyr build system can automatically sign the final image for you. +To enable this functionality, you will have to set: + +* `MCUBOOT_SIGNATURE_KEY_FILE`: path to the signing key +* `MCUBOOT_IMGTOOL_SIGN_VERSION`: version of the produced image +before building your application. +Here's a modification of the build command from [building the image](#building-the-image) with those settings applied: + +```sh + west build \ + -d build \ + -b stm32f746g_disco \ + "~/zephyrproject/zephyr/samples/subsys/mgmt/mcumgr/smp_svr" \ + -- \ + -DDTC_OVERLAY_FILE="stm32_disco.overlay" \ + -DEXTRA_CONF_FILE="overlay-serial.conf" \ + -DCONFIG_MCUBOOT_BOOTLOADER_MODE_SWAP_SCRATCH=y \ + -DCONFIG_MCUBOOT_SIGNATURE_KEY_FILE='"key.pem"' \ + -DCONFIG_IMGTOOL_SIGN_VERSION='"1.2.3+4"' +``` + +##### Manually + +You can also sign the produced images yourself using the [image tool](#generating-image-signing-key). +Below is a sample showing how to sign previously built image: + +```sh +west sign -d build -t imgtool -- --key --version +``` + +Either way, the signed images will be stored next to their unsigned counterparts. They will have `signed` inserted into the filename (e.g. unsigned `zephyr.bin` will produce `zephyr.signed.bin` signed image). + +### Self-confirmed updates + +By default, MCUmgr client will try to manually confirm a new image during an update. +While this works in simple cases, you might wish to run some additional test logic that should be used to determine if an update should be finalized. +For example, you might want to reject an update in case one of the drivers failed to start or if the network stack is misconfigured. +The client supports these kinds of use cases using self-confirming images. +Rather than confirming an update by itself, +the client will instead watch the primary image slot of the device to determine if an update was marked as permanent or if it was rejected. +In that case, the final decision falls on the updated device. + +For this feature to work correctly, you will have to modify your application to include the self-testing logic. + +```c +/* + * An example of self-test function. + * It will first check if this is a fresh update and run the testing logic. + * Based on results, it will either mark the update as permanent or reboot, + * causing MCUboot to revert to the previous version. + * + * This function should be called before the main application logic starts, + * preferably at the beginning of the `main` function. + */ + +#include +#include + +void run_self_tests() { + if (!boot_is_img_confirmed()) { + bool passed; + + /* Testing logic goes here */ + + if (!passed) { + sys_reboot(SYS_REBOOT_COLD); // (1) + return; + } + + boot_write_img_confirmed(); // (2) + } +} +``` +::::{code-annotations} +1.

API authentication **must** be enabled; `RDFM_DISABLE_API_AUTH` **must not** be set. +3. RDFM **must** use a production WSGI server; `RDFM_WSGI_SERVER` **must not** be set to `werkzeug`. + When not provided, the server defaults to using a production-ready WSGI server (`gunicorn`). + The development server (`werkzeug`) does not provide sufficient performance to handle production workloads, and a high percentage of requests will be dropped under heavy load. +4.

Each group can also be assigned one or many packages. +The group itself also contains metadata about the group name, description, update policy, and other arbitrary information which can be used by custom frontends interacting with the server. + +### Update policy + +An update policy defines the target version the devices within a given group will be updated to. +The policy is a string with the syntax `,[arguments]`. +Required arguments depend on the specific policy being used. +Currently, the following policies are supported: +- `no_update` (**default**) - requires no arguments, the server will treat all devices within the group as up-to-date, and will not return any packages to devices requesting an update check. **This is the default update policy for all newly created groups**. +- `exact_match` - specifies that the server will attempt to install the target software version on each of the devices in the group. +Example usage: `exact_match,version1` - this specifies that the server will attempt to bring all of the devices to the software version `version1`. +This process may involve installing many intermediate packages, but the end result is a device that's running the specified version. +The server will use group-assigned packages when resolving the dependency graph required for reaching the target version. + +## Update resolution + +When resolving a path to the correct target version, the server utilizes only the group-assigned packages. +When a device is requesting an update check, a package dependency graph is created. +The edges of the graph correspond to different packages available during the update process (which are compatible with the device, as indicated by the `rdfm.hardware.devtype` field), while the nodes indicate the software versions (as indicated by the `rdfm.software.version` fields of each package). +Next, the group's update policy is queried, which indicates the target version/node each device should be attempting to reach. +The shortest path between the currently running node and the target node is used as instructions for how the server should lead the device to the specified version. + +## Example scenario: simple update assignment + +Consider a group with the following packages assigned: +- P0 - `devtype=foo`, `version=v1` +- P1 - `devtype=bar`, `version=v2` +- P2 - `devtype=baz`, `version=v3` + +The group is specified to update to version `v3` per the policy.

RDFM Server API Reference

+

API Authentication

+

By default, the RDFM server expects all API requests to be authenticated. +Depending on the type of the API, this can be either:

+
    +

  • Device Token

    • +

  • Management Token

    • +
+

In either case, the server expects the token to be passed as part of the request, in the HTTP Authorization header. +An example authenticated request is shown below:

+
GET /api/v1/groups HTTP/1.1
+Host: rdfm-server:5000
+User-Agent: python-requests/2.31.0
+Accept-Encoding: gzip, deflate
+Accept: */*
+Connection: keep-alive
+Authorization: Bearer token=eyJhbGciOiJSUzI1NiIsInR5cC<...truncated...>RpPonb7-IAsk89YpGayxg
+
+
+

Any request that was not successfully authenticated (because of a missing or otherwise invalid token) will return the 401 Unauthorized status code. +Additionally, in the case of management tokens, if the given token does not provide sufficient access to the requested resource, the request will be rejected with a 403 Forbidden status code. +This can happen if the token does not claim all scopes required by the target endpoint (for example: trying to upload a package using a read-only token).

+

Error Handling

+

Should an error occur during the handling of an API request, either because of incorrect request data or other endpoint-specific scenarios, the server will return an error structure containing a user-friendly description of the error. +An example error response is shown below:

+
{
+   "error": "delete failed, the package is assigned to at least one group"
+}
+
+
+

Packages API

+

The RDFM Android Device Client allows for integrating an Android-based device with the RDFM server. +Currently, only OTA update functionality is implemented.

+

Integrating the app

+

This app is not meant to be built separately (i.e in Android Studio), but as part of the source tree for an existing device. +The app integrates with the Android UpdateEngine to perform the actual update installation, which requires it to be a system app. +Some configuration is required to the existing system sources.

+

Copying the sources

+

First, copy the sources of the app to the root directory of the AOSP source tree. +After cloning this repository, run the following:

+
mkdir -v -p <path-to-aosp-tree>/vendor/antmicro/rdfm
+cd devices/android-client/
+cp -r app/src/main/* <path-to-aosp-tree>/vendor/antmicro/rdfm
+
+
+

Configuring the device Makefile

+

The product Makefile must be configured to build the RDFM app into the system image. +To do this, add rdfm to the PRODUCT_PACKAGES variable in the target device Makefile:

+
PRODUCT_PACKAGES += rdfm
+
+
+

Building the app

+

Afterwards, the usual Android build procedure can be used to build just the app. +From an already configured build environment, run:

+
mma rdfm
+
+
+

The resulting signed APK is in out/target/product/<product-name>/system/app/rdfm/rdfm.apk.

+

Using HTTPS for server requests

+

The default Android system CA certificates are used when validating the certificate presented by the server. +If the RDFM server that is configured in the app uses a certificate that is signed by a custom Certificate Authority, the CA certificate must be added to the system roots.

+

System versioning

+

The app performs update check requests to the configured RDFM server. +The build version and device type are retrieved from the system properties:

+
    +

  • ro.build.version.incremental - the current software version (matches rdfm.software.version)

    • +

  • ro.build.product - device type (matches rdfm.hardware.devtype)

    • +
+

When uploading an OTA package to the RDFM server, currently these values must be manually extracted from the update package, and passed as arguments to rdfm-mgmt:

+
rdfm-mgmt packages upload --path ota.zip --version <ro.build.version.incremental> --device <ro.build.product>
+
+
+

You can extract the values from the package metadata file by unzipping the OTA package.

+

Configuring the app

+

The application will automatically start on system boot. +Available configuration options are shown below.

+

Build-time app configuration

+

The default build-time configuration can be modified by providing a custom conf.xml file in the app/src/main/res/values/ folder, similar to the one shown below:

+
<?xml version="1.0" encoding="utf-8"?>
+<resources>
+<!--
+    This is an example overlay configuration file for the RDFM app.
+    To modify the default server address, you can do:
+
+        <string name="default_rdfm_server_address">http://rdfm.example.local:6000/</string>
+
+    Likewise, overlaying the default update check interval can be done similarly:
+
+        <string name="default_update_check_interval_seconds">240</string>
+
+    NOTE: These settings are only used during the app's first startup. To change them afterwards,
+    you must delete the existing configuration file.
+-->
+</resources>
+
+
+

This build-time configuration is applied only once, at first startup of the app, as the main use case for this is first-time configuration for newly provisioned devices. +Modifying it afterwards (for example, via an update containing a new version of the RDFM app) will not result in the change of existing configuration.

+

Runtime app configuration

+

It is possible to change the app’s configuration at runtime by simply starting the RDFM app from the drawer and selecting Settings from the context menu.

+

Configuration options

+

The following configuration options are available:

+
    +

  • RDFM server URL (http/https scheme)

    • +

  • Update check interval (in seconds)

    • +

  • Maximum amount of concurrent shell sessions (set to 0 to disable reverse shell functionality)

    • +
+

Available intents

+

Update check intent

+

This intent allows an external app to force perform an update check outside of the usual automatic update check interval. +To do this, the app that wants to perform the update check must have the com.antmicro.update.rdfm.permission.UPDATE_CHECK permission defined in its AndroidManifest.xml file:

+
<uses-permission android:name="com.antmicro.update.rdfm.permission.UPDATE_CHECK" />
+
+
+

Afterwards, an update check can then be forced like so:

+
Intent configIntent = new Intent("com.antmicro.update.rdfm.startUpdate");
+mContext.sendBroadcast(configIntent);
+
+
+

External configuration via intents

+

The app settings can also be configured via intents, for example in order to change between different deployment environments. +To do this, the app that performs the configuring step must have the com.antmicro.update.rdfm.permission.CONFIGURATION permission defined in its AndroidManifest.xml file:

+
<uses-permission android:name="com.antmicro.update.rdfm.permission.CONFIGURATION" />
+
+
+

To configure the app, use the com.antmicro.update.rdfm.configurationSet intent and set extra values on the intent to the settings you wish to change. +For example, to set the server address:

+
Intent configIntent = new Intent("com.antmicro.update.rdfm.configurationSet");
+configIntent.putExtra("ota_server_address", "http://CUSTOM-OTA-ADDRESS/");
+mContext.sendBroadcast(configIntent);
+
+
+

The supported configuration key names can be found in the res/values/strings.xml file with the preference_ prefix.

+

Aside from setting the configuration, you can also fetch the current configuration of the app:

+
Intent configIntent = new Intent("com.antmicro.update.rdfm.configurationGet");
+mContext.sendBroadcast(configIntent);
+
+// Now listen for `com.antmicro.update.rdfm.configurationResponse` broadcast intent
+// The intent's extras bundle will contain the configuration keys and values
+
+
+

Development

+

The provided Gradle files can be used for development purposes, simply open the devices/android-client directory in Android Studio. +Missing references to the UpdateEngine class are expected, but they do not prevent regular use of the IDE.

+

Do note however that the app is not buildable from Android Studio, as it requires integration with the aforementioned system API. +To test the app, an existing system source tree must be used. +Copy the modified sources to the AOSP tree, and re-run the application build. +The modified APK can then be uploaded to the device via ADB by running:

+
adb install <path-to-rdfm.apk>
+
+
+

Restarting the app

+

With the target device connected via ADB, run:

+
adb shell am force-stop com.antmicro.update.rdfm
+adb shell am start -n com.antmicro.update.rdfm/.MainActivity
+
+
+

Fetching app logs

+

To view the application logs, run:

+
adb logcat --pid=`adb shell pidof -s com.antmicro.update.rdfm`

RDFM Artifact utility

+

Introduction

+

The RDFM Artifact tool (rdfm-artifact) allows for easy creation and modification of RDFM Linux client-compatible artifacts containing rootfs partition images. +A basic RDFM artifact consists of a rootfs image, as well as its checksum, metadata and compatibility with certain device types.

+

Additionally, rdfm-artifact allows for the generation of delta updates, which contain only the differences between two versions of an artifact rather than the entire artifact itself. +This can be useful for reducing the size of updates and improving the efficiency of the deployment process.

+

rdfm-artifact can also be used for generation of Zephyr MCUboot artifacts, which allows for updating embedded devices running Zephyr. +Additionally, multiple Zephyr images can be combined into one grouped artifact to allow multiple boards to act as one logical device.

+

Getting started

+

In order to support robust updates and rollback, the RDFM Client requires proper partition layout and a bootloader that supports A/B update scheme. To make it easy to integrate the RDFM Client into your Yocto image-building project, it’s recommended to use the meta-rdfm Yocto layer when building the BSPs.

+

Building from source

+

Requirements

+
    +

  • Go compiler

    • +

  • C Compiler

    • +

  • liblzma-dev and libglib2.0-dev packages

    • +
+

Steps

+

To build rdfm-artifact on a device from source, clone the repository and build the binary using make:

+
git clone https://github.com/antmicro/rdfm.git && cd tools/rdfm-artifact/
+make
+
+
+

Basic usage

+

The basic functionality of writing an artifact is available with the write subcommand:

+
NAME:
+   rdfm-artifact write - Allows creation of RDFM-compatible artifacts
+
+USAGE:
+   rdfm-artifact write command [command options] [arguments...]
+
+COMMANDS:
+   rootfs-image        Create a full rootfs image artifact
+   delta-rootfs-image  Create a delta rootfs artifact
+   zephyr-image        Create a full Zephyr MCUboot image artifact
+   zephyr-group-image  Create a Zephyr MCUboot group image artifact
+
+OPTIONS:
+   --help, -h  show help
+
+
+

Creating a full-rootfs artifact

+

For example, to create a simple rootfs artifact for a given system image:

+
rdfm-artifact write rootfs-image \
+	--file "my-rootfs-image.img" \
+	--artifact-name "my-artifact-name" \
+	--device-type "my-device-type" \
+	--output-path "path-to-output.rdfm"
+
+
+

Creating a delta rootfs artifact

+

For creating a delta artifact, you should have already created two separate full-rootfs artifacts:

+
    +

  • base artifact - the rootfs image that the deltas will be applied on top of, or in other words: the currently running rootfs on the device

    • +

  • target artifact - the updated rootfs image that will be installed on the device

    • +
+

Given these two artifacts, a delta artifact can be generated like this:

+
rdfm-artifact write delta-rootfs-image \
+    --base-artifact "base.rdfm" \
+    --target-artifact "target.rdfm" \
+    --output-path "base-to-target.rdfm"
+
+
+

Creating a Zephyr MCUboot artifact

+

To create a Zephyr MCUboot artifact, you’ll have to have already created a Zephyr image with MCUboot support enabled. +You should use the signed bin image (by default zephyr.signed.bin). +Artifact version will be extracted from provided image.

+

With this image, you can generate an artifact like so:

+
rdfm-artifact write zephyr-image \
+   --file "my-zephyr-image.signed.bin" \
+   --artifact-name "my-artifact-name" \
+   --device-type "my-device-type" \
+   --output-path "path-to-output.rdfm"
+
+
+

Creating a Zephyr MCUboot group artifact

+

To create a grouped Zephyr MCUboot artifact, you should have already created at least two Zephyr images with MCUboot support enabled. +The version of individual images in a grouped artifact must be identical.

+

Given images one.bin and two.bin for group targets one and two respectively, an artifact can be generated with:

+
rdfm-artifact write zephyr-group-image \
+	--group-type "my-group" \
+	--target "one:one.bin" \
+	--target "two:two.bin" \
+	--ouptput-path "path-to-output.rdfm"
+
+
+
+

Note

+

It’s possible to create a grouped artifact with just one image, +however in cases like that you should create simple zephyr-image instead.

+
+

Running tests

+

To run rdfm-artifact tests, use the test Makefile target:

+
make test

RDFM Linux Device Client

+

Introduction

+

The RDFM Linux Device Client (rdfm-client) integrates an embedded Linux device with the RDFM Server. +This allows for performing robust Over-The-Air (OTA) updates of the running system and remote management of the device.

+

rdfm-client runs on the target Linux device and handles the process of checking for updates in the background along with maintaining a connection to the RDFM Management Server.

+

Getting started

+

In order to support robust updates and rollback, the RDFM Client requires proper partition layout and integration with the U-Boot bootloader. To make it easy to integrate the RDFM Client into your Yocto image-building project, it’s recommended to use the meta-rdfm Yocto layer when building the BSPs.

+

Installing from source

+

Requirements

+
    +

  • C compiler

    • +

  • Go compiler

    • +

  • liblzma-dev, libssl-dev and libglib2.0-dev packages

    • +
+

Steps

+

To install an RDFM client on a device from source, first clone the repository and build the binary:

+
git clone https://github.com/antmicro/rdfm.git && cd devices/linux-client/
+make
+
+
+

Then run the install command:

+
make install
+
+
+

Installation notes

+

Installing rdfm this way does not offer a complete system updater. +System updates require additional integration with the platform’s bootloader and a dual-root partition setup for robust updates. +For this, it’s recommended to build complete BSPs containing rdfm using the meta-rdfm Yocto layer.

+

Building using Docker

+

All build dependencies for compiling the RDFM Client are included in a dedicated Dockerfile. To build a development container image, you can use:

+
git clone https://github.com/antmicro/rdfm.git && cd devices/linux-client/
+sudo docker build -t rdfmbuilder .
+
+
+

This will create a Docker image that can be later used to compile the RDFM binary:

+
sudo docker run --rm -v <rdfm-dir>:/data -it rdfmbuilder
+cd data/devices/linux-client
+make
+
+
+

Testing server-device integration with a demo Linux device client

+

For development purposes, it’s often necessary to test server integration with an existing device client. +To do this, it is possible to use the RDFM Linux device client, without having to build a compatible system image utilizing the Yocto meta-rdfm layer. +First, build the demo container image:

+
cd devices/linux-client/
+make docker-demo-client
+
+
+

You can then start a demo Linux client by running the following:

+
docker-compose -f docker-compose.demo.yml up
+
+
+

If required, the following environment variables can be changed in the above docker-compose.demo.yml file:

+
    +

  • RDFM_CLIENT_SERVER_URL - URL to the RDFM Management Server, defaults to http://127.0.0.1:5000/.

    • +

  • RDFM_CLIENT_SERVER_CERT (optional) - path (within the container) to the CA certificate to use for verification of the connection to the RDFM server. When this variable is set, the server URL must also be updated to use HTTPS instead of HTTP.

    • +

  • RDFM_CLIENT_DEVTYPE - device type that will be advertised to the RDFM server; used for determining package compatibility, defaults to x86_64.

    • +

  • RDFM_CLIENT_PART_A, RDFM_CLIENT_PART_B (optional) - specifies path (within the container) to the rootfs A/B partitions that updates will be installed to. They do not need to be specified for basic integration testing; any updates that are installed will go to /dev/zero by default.

    • +
+

The demo client will automatically connect to the specified RDFM server and fetch any available packages. +To manage the device and update deployment, you can use the RDFM Manager utility.

+

Developer Guide

+

Running tests

+

Use the test make target to run the unit tests:

+
make test
+
+
+

Additionally, run the scripts available in the scripts/test-docker directory. These scripts test basic functionality of the RDFM client.

RDFM Manager utility

+

Introduction

+

The RDFM Manager (rdfm-mgmt) utility allows authorized users to manage resources exposed by the RDFM Management Server.

+

Installation

+

Before proceeding, make sure that you have installed Python (at least version 3.11) and the pipx utility:

+
    +

  • Debian (Bookworm) - run sudo apt update && sudo apt install pipx

    • +

  • Arch - sudo pacman -S python-pipx

    • +
+

The prefered mode of installation for rdfm-mgmt is via pipx. +To install rdfm-mgmt, you must first clone the RDFM repository:

+
git clone https://github.com/antmicro/rdfm.git
+cd rdfm/
+
+
+

Afterwards, run the following commands:

+
cd manager/
+pipx install .
+
+
+

This will install the rdfm-mgmt utility and its dependencies for the current user within a virtual environment located at /home/<user>/.local/pipx/venv. +The rdfm-mgmt executable will be placed in /home/<user>/.local/bin/ and should be immediately accessible from the shell. +Depending on the current system configuration, adding the above directory to the PATH may be required.

+

Configuration

+

Additional RDFM Manager configuration is stored in the current user’s $HOME directory, in the $HOME/.config/rdfm-mgmt/config.json file. +By default, RDFM Manager will add authentication data to all requests made to the RDFM server, which requires configuration of an authorization server and client credentials for use with the OAuth2 Client Credentials flow. +If authentication was disabled on the server-side, you can disable it in the manager as well by passing the --no-api-auth CLI flag like so:

+
rdfm-mgmt --no-api-auth groups list
+
+
+

An example configuration file is shown below. +In this case, the Keycloak authorization server was used:

+
{
+        "auth_url": "http://keycloak:8080/realms/master/protocol/openid-connect/token",
+        "client_id": "rdfm-client",
+        "client_secret": "RDSwDyUMOT7UXxMqMmq2Y4vQ1ezxqobi"
+}
+
+
+

Explanation of each required configuration field is shown below:

+
    +

  • auth_url - URL to the authorization server’s token endpoint

    • +

  • client_id - Client ID to use for authentication using OAuth2 Client Credentials flow

    • +

  • client_secret - Client secret to use for authentication using OAuth2 Client Credentials flow

    • +
+
+

Note

+

If you’re also setting up the server, please note that the above client credentials are NOT the same as the server’s Token Introspection credentials. +Each user of rdfm-mgmt should receive different credentials and be assigned scopes based on their allowed access level.

+
+

Building the wheel

+

For installation instructions, see the Installation section. +Building the wheel is not required in this case.

+

To build the rdfm-mgmt wheel, you must have Python 3 installed, along with the Poetry dependency manager.

+

Building the wheel can be done as follows:

+
cd manager/
+poetry build
+
+
+

Usage

+

For more detailed information, see the help messages associated with each subcommand:

+
$ rdfm-mgmt -h
+usage: rdfm-mgmt
+
+RDFM Manager utility
+
+options:
+  -h, --help            show this help message and exit
+  --url URL             URL to the RDFM Management Server (default: http://127.0.0.1:5000/)
+  --cert CERT           path to the server CA certificate used for establishing an HTTPS connection (default: ./certs/CA.crt)
+  --no-api-auth         disable OAuth2 authentication for API requests (default: False)

RDFM MCUmgr Device Client

+

Introduction

+

The RDFM MCUmgr Device Client (rdfm-mcumgr-client) allows for integrating an embedded device running ZephyrRTOS with the RDFM server via its MCUmgr SMP server implementation. +Currently, only the update functionality is implemented with support for serial, UDP and BLE transports.

+

rdfm-mcumgr-client runs on a proxy device that’s connected to the targets via one of the supported transports that handles the process of checking for updates, fetching update artifacts and pushing update images down to correct targets.

+

Getting started

+

In order to properly function, both the Zephyr application and the rdfm-mcumgr-client have to be correctly configured in order for the update functionality to work. +Specifically:

+
    +

  • Zephyr applications must be built with MCUmgr support, with any transport method of your choice and with image management and reboot command groups enabled.

    • +

  • The device running Zephyr must be connected to a proxy device running rdfm-mcumgr-client as the updates are coming from it.

    • +

  • For reliable updates, the SMP server must be running alongside your application and be accessible at all times.

    • +
+

Building client from source

+

Requirements

+
    +

  • C compiler

    • +

  • Go compiler (1.22+)

    • +

  • liblzma-dev and libssl-dev packages

    • +
+

Steps

+

To install the proxy client from source, first clone the repository and build the binary:

+
git clone https://github.com/antmicro/rdfm.git
+cd rdfm/devices/mcumgr-client/
+make
+
+
+

Then run the install command:

+
make install
+
+
+

Setting up target device

+

Setting up the bootloader

+

To allow rollbacks and update verification, the MCUboot bootloader is used. +Images uploaded by rdfm-mcumgr-client are written to a secondary flash partition, while leaving the primary (currently running) image intact. +During update, the images are swapped by the bootloader. +If the update was successful, the new image is permanently set as the primary one, otherwise the images are swapped back to restore the previous version. +For more details on MCUboot, you can read the official guide from MCUboot’s website.

+

Generating image signing key

+

In order to enable updates, MCUboot requires all images to be signed. +During update, the bootloader will first validate the image using this key.

+

MCUboot provides imgtool.py image tool script which can be used to generate appropriate signing key. +Below are the steps needed to generate a new key using this tool:

+

Install additional packages required by the tool (replace ~/zephyrproject with path to your Zephyr workspace):

+
cd ~/zephyrproject/bootloader/mcuboot
+pip3 install --user -r ./scripts/requirements.txt
+
+
+

Generate new key:

+
cd ~/zephyrproject/bootloader/mcuboot/scripts
+./imgtool.py keygen -k <filename.pem> -t <key-type>
+
+
+

MCUboot currently supports rsa-2048, rsa-3072, ecdsa-p256 or ed25519 key types. +For more details on the image tool, please refer to its official documentation.

+

Building the bootloader

+

Besides the signing key, MCUboot also requires that the target board has specific flash partitions defined in its devicetree. +These partitions are:

+
    +

  • boot_partition: for MCUboot itself

    • +

  • slot0_partition: the priamry slot of image 0

    • +

  • slot1_partition: the secondary slot of image 0

    • +
+

If you choose the swap-using-scratch update algorithm, one more partition has to be defined:

+
    +

  • scratch_partition: the scratch slot

    • +
+

You can check whether your board has those partitions predefined by looking at its devicetree file (boards/<arch>/<board>/<board>.dts). +Look for fixed-partitions compatible entry. If your default board configuration doesn’t specify those partitions (or you would like to modify them), +you can either modify the devicetree file directly or use devicetree overlays.

+

Sample overlay file for the stm32f746g_disco board:

+
#include <mem.h>
+
+/delete-node/ &quadspi;
+
+&flash0 {
+    partitions {
+        compatible = "fixed-partitions";
+        #address-cells = <1>;
+        #size-cells = <1>;
+
+        boot_partition: partition@0 {
+            label = "mcuboot";
+            reg = <0x00000000 DT_SIZE_K(64)>;
+        };
+
+        slot0_partition: partition@40000 {
+            label = "image-0";
+            reg = <0x00040000 DT_SIZE_K(256)>;
+        };
+
+        slot1_partition: partition@80000 {
+            label = "image-1";
+            reg = <0x00080000 DT_SIZE_K(256)>;
+        };
+
+        scratch_partition: partition@c0000 {
+        	label = "scratch";
+        	reg = <0x000c0000 DT_SIZE_K(256)>;
+        };
+    };
+};
+
+/ {
+    aliases {
+        /delete-property/ spi-flash0;
+    };
+
+    chosen {
+        zephyr,flash = &flash0;
+        zephyr,flash-controller = &flash;
+        zephyr,boot-partition = &boot_partition;
+        zephyr,code-partition = &slot0_partition;
+    };
+};
+
+
+
+

Note

+

If you do use devicetree overlay, make sure to add app.overlay as the last overlay file +since it’s needed to correctly store the MCUboot image in boot_partition.

+
+

Besides the devicetree, you also have to specify:

+
    +

  • BOOT_SIGNATURE_KEY_FILE: path to the previously generate signing key

    • +

  • BOOT_SIGNATURE_TYPE: signing key type:

    +
      +

    • BOOT_SIGNATURE_TYPE_RSA and BOOT_SIGNATURE_TYPE_RSA_LEN

      • +

    • BOOT_SIGNATURE_TYPE_ECDSA_P256

      • +

    • BOOT_SIGNATURE_TYPE_ED25519

      • +
    +
    • +

  • BOOT_IMAGE_UPGRADE_MODE: the update algorithm used for swapping images in primary and secondary slots:

    +
      +

    • BOOT_SWAP_USING_MOVE

      • +

    • BOOT_SWAP_USING_SCRATCH

      • +
    +
    • +
+

For example, if you wanted to build the bootloader for the stm32f746g_disco board with partitions defined in stm32_disco.overlay, +using swap-using-scratch update algorithm and using rsa-2048 key.pem signing key, +you would run (replace ~/zephyrproject with path to your Zephyr workspace):

+
    west build \
+        -d mcuboot \
+        -b stm32f746g_disco \
+        ~/zephyrproject/bootloader/mcuboot/boot/zephyr \
+        -- \
+            -DDTC_OVERLAY_FILE="stm32_disco.overlay;app.overlay" \
+            -DCONFIG_BOOT_SIGNATURE_KEYFILE='"key.pem"' \
+            -DCONFIG_BOOT_SIGNATURE_TYPE_RSA=y \
+            -DCONFIG_BOOT_SIGNATURE_TYPE_RSA_LEN=2048 \
+            -DCONFIG_BOOT_SWAP_USING_SCRATCH=y
+
+
+

The produced image can be flashed to your device. +For more details on building and using MCUboot with Zephyr, please refer to official MCUboot guide.

+

Setting up the Zephyr application

+

Building the image

+

To allow your application to be used with MCUmgr client, you will have to enable Zephyr’s device management subsystem. +For the client to function properly, both image management +and OS management groups need to be enabled. +You will also have to enable and configure SMP transport +(either serial, BLE or udp) that you wish to use. +To learn how to do that, you can reference Zephyr’s smp_svr sample +which provides configuration for all of them.

+

You will also have set MCUBOOT_BOOTLOADER_MODE setting to match the swapping algorithm you’ve configured for the bootloader:

+ + + + + + + + + + + + + + +

MCUboot

Zephyr

BOOT_SWAP_USING_MOVE

MCUBOOT_BOOTLOADER_MODE_SWAP_WITHOUT_SCRATCH

BOOT_SWAP_USING_SCRATCH

MCUBOOT_BOOTLOADER_MODE_SWAP_SCRATCH

+
+

Important

+

Bluetooth specific

+

Bluetooth transport additionally requires you to manually start SMB Bluetooth advertising. +Refer to the main.c +and bluetooth.c +from the smp_svr sample for details on that.

+
+

To build the smp_svr sample +for the stm32f746g_disco board with stm32_disco.overlay devicetree overlay, +configured to use serial transport with swap-using-scratch update algorithm, +you would run (replace ~/zephyrproject with path to your Zephyr workspace):

+
    west build \
+        -d build \
+        -b stm32f746g_disco \
+        "~/zephyrproject/zephyr/samples/subsys/mgmt/mcumgr/smp_svr" \
+        -- \
+            -DDTC_OVERLAY_FILE="stm32_disco.overlay" \
+            -DEXTRA_CONF_FILE="overlay-serial.conf" \
+            -DCONFIG_MCUBOOT_BOOTLOADER_MODE_SWAP_SCRATCH=y
+
+
+

For more information on the smp_svr sample, please refer to Zephyr’s documentation.

+

Signing the image

+

By default MCUboot will only accept images that are properly signed with the same key as the bootloader itself. +Only BIN and HEX output types can be signed. +The recommended way for managing signing keys is using MCUboot’s image tool, +which is shipped together with Zephyr’s MCUboot implementation. +When signing an image, you also have to provide an image version, that’s embedded in the signed image header. +This is also the value that will be reported by the MCUmgr client as the current running software version back to the RDFM server. +Image version is specified in major.minor.revision+build format.

+
Automatically
+

Zephyr build system can automatically sign the final image for you. +To enable this functionality, you will have to set:

+
    +

  • MCUBOOT_SIGNATURE_KEY_FILE: path to the signing key

    • +

  • MCUBOOT_IMGTOOL_SIGN_VERSION: version of the produced image +before building your application. +Here’s a modification of the build command from building the image with those settings applied:

    • +
+
    west build \
+        -d build \
+        -b stm32f746g_disco \
+        "~/zephyrproject/zephyr/samples/subsys/mgmt/mcumgr/smp_svr" \
+        -- \
+            -DDTC_OVERLAY_FILE="stm32_disco.overlay" \
+            -DEXTRA_CONF_FILE="overlay-serial.conf" \
+            -DCONFIG_MCUBOOT_BOOTLOADER_MODE_SWAP_SCRATCH=y \
+            -DCONFIG_MCUBOOT_SIGNATURE_KEY_FILE='"key.pem"' \
+            -DCONFIG_IMGTOOL_SIGN_VERSION='"1.2.3+4"'
+
+
+
Manually
+

You can also sign the produced images yourself using the image tool. +Below is a sample showing how to sign previously built image:

+
west sign -d build -t imgtool -- --key <key-file> --version <sign-version>
+
+
+

Either way, the signed images will be stored next to their unsigned counterparts. They will have signed inserted into the filename (e.g. unsigned zephyr.bin will produce zephyr.signed.bin signed image).

+

Self-confirmed updates

+

By default, MCUmgr client will try to manually confirm a new image during an update. +While this works in simple cases, you might wish to run some additional test logic that should be used to determine if an update should be finalized. +For example, you might want to reject an update in case one of the drivers failed to start or if the network stack is misconfigured. +The client supports these kinds of use cases using self-confirming images. +Rather than confirming an update by itself, +the client will instead watch the primary image slot of the device to determine if an update was marked as permanent or if it was rejected. +In that case, the final decision falls on the updated device.

+

For this feature to work correctly, you will have to modify your application to include the self-testing logic.

+
/*
+ * An example of self-test function.
+ * It will first check if this is a fresh update and run the testing logic.
+ * Based on results, it will either mark the update as permanent or reboot,
+ * causing MCUboot to revert to the previous version.
+ *
+ * This function should be called before the main application logic starts,
+ * preferably at the beginning of the `main` function.
+ */
+
+#include <zephyr/dfu/mcuboot.h>
+#include <zephyr/sys/reboot.h>
+
+void run_self_tests() {
+    if (!boot_is_img_confirmed()) {
+        bool passed;
+
+        /* Testing logic goes here */
+
+        if (!passed) {
+            sys_reboot(SYS_REBOOT_COLD); // (1)
+            return;
+        }
+
+        boot_write_img_confirmed(); // (2)
+    }
+}
+
+
    +

  1. Tests failed - device reboots itself, returning to previous version

    2. +

  2. Tests passed - device confirms the update, marking it as permanent

    3. +
+
+

Configuring MCUmgr client

+

Search locations

+

The client is configured using config.json configuration file. +By default, the client will look for this file in:

+
    +

  • current working directory

    • +

  • $HOME/.config/rdfm-mcumgr

    • +

  • /etc/rdfm-mcumgr

    • +
+

stopping at first configuration file found. +You can override this by specifying path to a different configuration file with -c/--config flag:

+
rdfm-mcumgr-client --config <path-to-config>
+
+
+

All of the non-device specific options can also be overwritten by specifying their flag counterpart. +For a full list you can run:

+
rdfm-mcumgr-client --help
+
+
+

      • +
    +
    • +
+

Device groups

+

The client supports grouping multiple Zephyr MCUboot boards to act as one complete device from management server’s perspective. +While each device in a group can be running different Zephyr application, +all devices are synchronized by the MCUmgr client to be running the exact same software version. +Group updates are performed using zephyr group artifacts +which contain update images for each member of the group and metadata on how to match image to device.

+

During an update, the MCUmgr client matches each image to its target member and tries to apply it. +Group update is considered successful only if all members of the group went through the update process without errors. +Otherwise all members are rolled back by the client to the previous version.

+

Device keys

+

Each device uses its own private key for authentication with rdfm-server as described in device authentication. +Each key should be stored under key_dir specified in configuration. +If the client doesn’t find corresponding device key for configured device, it will attempt to generate one itself. +The resulting key will be saved to the configured location with 0600 permissions.

+
+

Note

+

Device keys are different from the signing key used for signing the bootloader and application images!

RDFM Management Server

+

Introduction

+

The RDFM Management Server is a core part of the RDFM ecosystem. The server manages incoming device connections and grants authorization only to those which are allowed to check-in with the server. +It also handles package upload and management, deploy group management and other crucial functionality required for robust and secure device Over-The-Air (OTA) updates along with allowing remote system management without exposing devices to the outside world.

+

REST API

+

The server exposes a management and device API that is used by management software and end devices. A comprehensive list of all API endpoints is available in the RDFM Server API Reference chapter.

+

Setting up a Dockerized development environment

+

The preferred method for running the RDFM server is by using a Docker container. +To set up a local development environment, first clone the RDFM repository:

+
git clone https://github.com/antmicro/rdfm.git
+cd rdfm/
+
+
+

A Dockerfile is provided in the server/deploy/ directory that builds a container suitable for running the server. +Currently, it is required to build the container image manually. +To do this, run the following from the cloned RDFM repository root folder:

+
docker build -f server/deploy/Dockerfile -t antmicro/rdfm-server:latest .
+
+
+

A simple docker-compose file that can be used to run the server is provided below, and in the server/deploy/docker-compose.development.yml file.

+
services:
+  rdfm-server:
+    image: antmicro/rdfm-server:latest
+    restart: unless-stopped
+    environment:
+      - RDFM_JWT_SECRET=<REPLACE_WITH_CUSTOM_JWT_SECRET>
+      - RDFM_DB_CONNSTRING=sqlite:////database/development.db
+      - RDFM_HOSTNAME=rdfm-server
+      - RDFM_API_PORT=5000
+      - RDFM_DISABLE_ENCRYPTION=1
+      - RDFM_DISABLE_API_AUTH=1
+      - RDFM_LOCAL_PACKAGE_DIR=/packages/
+      - RDFM_WSGI_SERVER=werkzeug
+    ports:
+      - "5000:5000"
+    volumes:
+      - db:/database/
+      - pkgs:/packages/
+
+volumes:
+  db:
+  pkgs:
+
+
+

The server can then be started using the following command:

+
docker-compose -f server/deploy/docker-compose.development.yml up
+
+
+

Configuration via environment variables

+

Configuration of the RDFM server can be changed by using the following environment variables:

+
    +

  • RDFM_JWT_SECRET - secret key used by the server when issuing JWT tokens, this value must be kept secret and not easily guessable (for example, a random hexadecimal string).

    • +

  • RDFM_DB_CONNSTRING - database connection string, for examples please refer to: SQLAlchemy - Backend-specific URLs. Currently, only the SQLite and PostgreSQL engines were verified to work with RDFM (however: the PostgreSQL engine requires adding additional dependencies which are currently not part of the default server image, this may change in the future).

    • +
+

Development configuration:

+
    +

  • RDFM_DISABLE_ENCRYPTION - if set, disables the use of HTTPS, falling back to exposing the API over HTTP. This can only be used in production if an additional HTTPS reverse proxy is used in front of the RDFM server.

    • +

  • RDFM_DISABLE_API_AUTH - if set, disables request authentication on the exposed API routes. WARNING: This is a development flag only! Do not use in production! This causes all API methods to be freely accessible, without any access control in place!

    • +
+

HTTP/WSGI configuration:

+
    +

  • RDFM_HOSTNAME - hostname/IP address to listen on. This is additionally used for constructing package URLs when storing packages in a local directory.

    • +

  • RDFM_API_PORT - API port.

    • +

  • RDFM_SERVER_CERT - required when HTTPS is enabled; path to the server’s certificate. The certificate can be stored on a Docker volume mounted to the container. For reference on generating the certificate/key pairs, see the server/tests/certgen.sh script.

    • +

  • RDFM_SERVER_KEY - required when HTTPS is enabled; path to the server’s private key. Additionally, the above also applies here.

    • +

  • RDFM_WSGI_SERVER - WSGI server to use, this value should be left default. Accepted values: gunicorn (default, production-ready), werkzeug (recommended for development).

    • +

  • RDFM_WSGI_MAX_CONNECTIONS - (when using Gunicorn) maximum amount of connections available to the server worker. This value must be set to at minimum the amount of devices that are expected to be maintaining a persistent (via WebSocket) connection with the server. Default: 4000.

    • +
+

API OAuth2 configuration (must be present when RDFM_DISABLE_API_AUTH is omitted):

+
    +

  • RDFM_OAUTH_URL - specifies the URL to an authorization server endpoint compatible with the RFC 7662 OAuth2 Token Introspection extension. This endpoint is used to authorize access to the RDFM server based on tokens provided in requests made by API users.

    • +

  • RDFM_OAUTH_CLIENT_ID - if the authorization server endpoint provided in RDFM_OAUTH_URL requires the RDFM server to authenticate, this variable defines the OAuth2 client_id used for authentication.

    • +

  • RDFM_OAUTH_CLIENT_SEC - if the authorization server endpoint provided in RDFM_OAUTH_URL requires the RDFM server to authenticate, this variable defines the OAuth2 client_secret used for authentication.

    • +
+

Package storage configuration:

+
    +

  • RDFM_STORAGE_DRIVER - storage driver to use for storing artifacts. Accepted values: local (default), s3.

    • +

  • RDFM_LOCAL_PACKAGE_DIR - specifies a path (local for the server) to a directory where the packages are stored.

    • +

  • RDFM_S3_BUCKET - when using S3 storage, name of the bucket to upload the packages to.

    • +

  • RDFM_S3_ACCESS_KEY_ID - when using S3 storage, Access Key ID to access the specified bucket.

    • +

  • RDFM_S3_ACCESS_SECRET_KEY - when using S3 storage, Secret Access Key to access the specified bucket.

    • +
+

Configuring package storage location

+

Storing packages locally

+

By default (when not using one of the above deployment setups), the server stores all uploaded packages to a temporary folder under /tmp/.rdfm-local-storage/. +To persist package data, configuration of an upload folder is required. +This can be done by using the RDFM_LOCAL_PACKAGE_DIR environment variable (in the Dockerized deployment), which should contain a path to the desired upload folder.

+
+

Warning

+

This storage method should NOT be used for production deployments! +The performance of the built-in file server is severely limited and provides NO caching, which will negatively affect the update speed for all devices even when a few of them try downloading an update package at the same time. +It is recommended to use a dedicated storage solution such as S3 to store packages.

+
+

Storing packages on S3-compatible storage

+

The RDFM server can also store package data on S3 and other S3 API-compatible object storage servers. +The following environment variables allow changing the configuration of the S3 integration:

+
    +

  • RDFM_S3_BUCKET - name of the bucket to upload the packages to

    • +

  • RDFM_S3_ACCESS_KEY_ID - Access Key ID to access the specified bucket

    • +

  • RDFM_S3_ACCESS_SECRET_KEY - Secret Access Key to access the specified bucket +Additionally, when using S3 storage, the environment variable RDFM_STORAGE_DRIVER must be set to s3.

    • +
+

An example reference setup utilizing the MinIO Object Storage server is provided in the server/deploy/docker-compose.minio.yml file. +To run it, first build the RDFM server container like in the above setup guides:

+
docker build -f server/deploy/Dockerfile -t antmicro/rdfm-server:latest .
+
+
+

Then, run the following:

+
docker-compose -f server/deploy/docker-compose.minio.development.yml up
+
+
+

Configuring API authentication

+

Basic configuration

+

The above development setup does not provide any authentication for the RDFM API. +This is helpful for development or debugging purposes, however under no circumstance should this be used in production deployments, as it exposes the entire API with no restrictions in place.

+

By default, the RDFM server requires configuration of an external authorization server to handle token creation and scope management. +To be compatible with RDFM Management Server, the authentication server MUST support the OAuth2 Token Introspection extension (RFC 7662).

+

The authorization server is configured using the following environment variables:

+
    +

  • RDFM_OAUTH_URL - specifies the URL to the Token Introspection endpoint of the authorization server.

    • +

  • RDFM_OAUTH_CLIENT_ID - specifies the client identifier to use for authenticating the RDFM server to the authorization server.

    • +

  • RDFM_OAUTH_CLIENT_SEC - specifies the client secret to use for authenticating the RDFM server to the authorization server.

    • +
+

For accessing the management API, the RDFM server does not issue any tokens itself. +This task is delegated to the authorization server that is used in conjunction with RDFM. +The following scopes are used for controlling access to different methods of the RDFM API:

+
    +

  • rdfm_admin_ro - read-only access to the API (fetching devices, groups, packages)

    • +

  • rdfm_admin_rw - complete administrative access to the API with modification rights

    • +
+

Refer to the RDFM Server API Reference chapter for a breakdown of the scopes required for accessing each API method.

+

API authentication using Keycloak

+

Running the services

+

An example docker-compose file that can be used to run the RDFM server using Keycloak Identity and Access Management server as an authorization server is provided below, and in the server/deploy/docker-compose.keycloak.development.yml file.

+
services:
+  rdfm-server:
+    image: antmicro/rdfm-server:latest
+    restart: unless-stopped
+    environment:
+      - RDFM_JWT_SECRET=<REPLACE_WITH_CUSTOM_JWT_SECRET>
+      - RDFM_DB_CONNSTRING=sqlite:////database/development.db
+      - RDFM_HOSTNAME=rdfm-server
+      - RDFM_API_PORT=5000
+      - RDFM_DISABLE_ENCRYPTION=1
+      - RDFM_LOCAL_PACKAGE_DIR=/packages/
+      - RDFM_OAUTH_URL=http://keycloak:8080/realms/master/protocol/openid-connect/token/introspect
+      - RDFM_OAUTH_CLIENT_ID=rdfm-server-introspection
+      - RDFM_OAUTH_CLIENT_SEC=<REPLACE_WITH_RDFM_INTROSPECTION_SECRET>
+    networks:
+      - rdfm
+    ports:
+      - "5000:5000"
+    volumes:
+      - db:/database/
+      - pkgs:/packages/
+
+  keycloak:
+    image: quay.io/keycloak/keycloak:22.0.1
+    restart: unless-stopped
+    environment:
+      - KEYCLOAK_ADMIN=admin
+      - KEYCLOAK_ADMIN_PASSWORD=admin
+    networks:
+      - rdfm
+    ports:
+      - "8080:8080"
+    command:
+      - start-dev
+    volumes:
+      - keycloak:/opt/keycloak/data/
+
+volumes:
+  db:
+  pkgs:
+  keycloak:
+
+networks:
+  rdfm:
+
+
+

Before running the above services, you must first build the RDFM server container by running the following from the RDFM repository root folder:

+
docker build -f server/deploy/Dockerfile -t antmicro/rdfm-server:latest .
+
+
+

You can then run the services by running:

+
docker-compose -f server/deploy/docker-compose.keycloak.development.yml up
+
+
+

Keycloak configuration

+

Further configuration on the Keycloak server is required before any requests are successfully authenticated. +First, navigate to the Keycloak Administration Console found at http://localhost:8080/ and login with the initial credentials provided in Keycloak’s configuration above (by default: admin/admin).

+

Next, go to Clients and press Create client. +This client is required for the RDFM server to perform token validation. +The following settings must be set when configuring the client:

+
    +

  • Client ID - must match RDFM_OAUTH_CLIENT_ID provided in the RDFM server configuration, can be anything (for example: rdfm-server-introspection)

    • +

  • Client Authentication - set to On

    • +

  • Authentication flow - select only Service accounts roles

    • +
+

After saving the client, go to the Credentials tab found under the client details. +Make sure the authenticator used is Client Id and Secret, and copy the Client secret. +This secret must be configured in the RDFM server under the RDFM_OAUTH_CLIENT_SEC environment variable.

+
+

Note

+

After changing the docker-compose variables, remember to restart the services (by pressing Ctrl+C and re-running the docker-compose up command).

+
+

Additionally, you must create proper client scopes to define which users have access to the read-only and read-write parts of the RDFM API. +To do this, navigate to the Client scopes tab and select Create client scope. +Create two separate scopes with the following names; the rest of the settings can be left as default (if required, you may also add a description to the scope):

+
    +

  • rdfm_admin_ro

    • +

  • rdfm_admin_rw

    • +
+

After restarting the services, the RDFM server will now validate requests against the Keycloak server.

+

Adding an API user

+

First, navigate to the Keycloak Administration Console found at http://localhost:8080/ and login with the initial credentials provided in Keycloak’s configuration above (by default: admin/admin).

+

Next, go to Clients and press Create client. +This client will represent a user of the RDFM API. +The following settings must be set when configuring the client:

+
    +

  • Client Authentication - set to On

    • +

  • Authentication flow - select only Service accounts roles

    • +
+

After saving the client, go to the Credentials tab found under the client details. +Make sure the authenticator used is Client Id and Secret, and copy the Client secret.

+

Finally, assign the required scope to the client: under the Client scopes tab, click Add client scope and select one of the two RDFM scopes: read-only rdfm_admin_ro or read-write rdfm_admin_rw.

+
+

Note

+

The newly-created client will now have access to the RDFM API. +To configure rdfm-mgmt to use this client, follow the Configuration section of the RDFM manager manual.

+
+

Configuring HTTPS

+

For simple deployments, the server can expose an HTTPS API directly without requiring an additional reverse proxy. +Configuration of the server’s HTTPS can be done using the following environment variables:

+
    +

  • RDFM_SERVER_CERT - path to the server’s signed certificate

    • +

  • RDFM_SERVER_KEY - path to the server’s private key

    • +
+

Both of these files must be accessible within the server Docker container.

+

HTTPS demo deployment

+
+

Warning

+

This demo deployment explicitly disables API authentication, and is only meant to be used as a reference on how to configure your particular deployment.

+
+

An example HTTPS deployment can be found in the server/deploy/docker-compose.https.development.yml file. +Before running it, you must execute the tests/certgen.sh in the server/deploy/ directory:

+
cd server/deploy/
+../tests/certgen.sh
+
+
+

This script generates a root CA and an associated signed certificate to be used for running the server. +The following files are generated:

+
    +

  • certs/CA.{crt,key} - CA certificate/private key that is used as the root of trust

    • +

  • certs/SERVER.{crt,key} - signed certificate/private key used by the server

    • +
+

To run the deployment, you must first build the RDFM server container by running the following from the RDFM repository root folder:

+
docker build -f server/deploy/Dockerfile -t antmicro/rdfm-server:latest .
+
+
+

You can then start the deployment by running:

+
docker-compose -f server/deploy/docker-compose.https.development.yml up
+
+
+

To verify the connection to the server, you must provide the CA certificate. +For example, when using curl to access API methods:

+
curl --cacert server/deploy/certs/CA.crt https://127.0.0.1:5000/api/v1/devices
+
+
+

When using rdfm-mgmt:

+
rdfm-mgmt --url https://127.0.0.1:5000/     \
+          --cert server/deploy/certs/CA.crt \
+          --no-api-auth                     \
+          devices list
+
+
+

Production deployments

+

Production considerations

+

The following is a list of considerations when deploying the RDFM server:

+
    +

  1. HTTPS must be enabled; RDFM_DISABLE_ENCRYPTION must not be set (or the server is behind a dedicated reverse proxy that adds HTTPS on the edge).

    2. +

  2. API authentication must be enabled; RDFM_DISABLE_API_AUTH must not be set.

    3. +

  3. RDFM must use a production WSGI server; RDFM_WSGI_SERVER must not be set to werkzeug. +When not provided, the server defaults to using a production-ready WSGI server (gunicorn). +The development server (werkzeug) does not provide sufficient performance to handle production workloads, and a high percentage of requests will be dropped under heavy load.

    4. +

  4. RDFM must use a dedicated (S3) package storage location; the local directory driver does not provide adequate performance when compared to dedicated object storage.

    5. +
+

Refer to the above configuration chapters for how to configure each aspect of the RDFM server:

+
    +

  1. Configuring HTTPS

    2. +

  2. Configuring API authentication

    3. +

  3. Configuring the WSGI server

    4. +

  4. Configuring S3 package storage

    5. +
+

A practical example of a deployment that includes all the above considerations can be found below, in the Production example deployment section.

+

Production example deployment

+
+

Warning

+

For simplicity, this example deployment has static credentials pre-configured pretty much everywhere, and as such should never be used directly as a production setup. +At least the following secrets are pre-configured and would require changes:

+
    +

  • S3 Access Key ID/Access Secret Key

    • +

  • rdfm-server JWT secret

    • +

  • Keycloak Administrator username/password

    • +

  • Keycloak Client: rdfm-server introspection Client ID/Secret

    • +

  • Keycloak Client: rdfm-mgmt admin user Client ID/Secret

    • +
+

Additionally, the Keycloak server requires further configuration for production deployments. +For more information, refer to the Configuring Keycloak for production page in Keycloak documentation.

+
+

A reference setup is provided in server/deploy/docker-compose.production.yml that can be used for customizing production server deployments. +Prior to starting the deployment, you must generate a signed server certificate that will be used for establishing the HTTPS connection to the server. +This can be done by either providing your own certificate, or by running the provided example certificate generation script:

+
cd server/deploy/
+../tests/certgen.sh
+
+
+

When using the certgen.sh script, the CA certificate found at server/deploy/certs/CA.crt can be used for validating the connection made to the server.

+

Similarly to previous example deployments, it can be started by running the following command from the RDFM monorepository root folder:

+
docker-compose -f server/deploy/docker-compose.production.yml up
+
+
+

rdfm-mgmt configuration for this deployment can be found in server/deploy/test-rdfm-mgmt-config.json. +After copying the configuration to $HOME/.config/rdfm-mgmt/config.json, you can access the server by running:

+
rdfm-mgmt --url https://127.0.0.1:5000/ --cert server/deploy/CA.crt \
+          devices list

RDFM OTA Manual

+

This chapter contains key information about the RDFM OTA update system.

+

Key concepts

+

Below is a brief explanation of the key entities of the RDFM update system.

+

Devices

+

From the server’s point of view, a device is any system that is running an RDFM-compatible update client. +For example, see RDFM Linux Device Client. +Each device actively reports its metadata to the server:

+
    +

  • Currently running software version (rdfm.software.version)

    • +

  • Device type (rdfm.hardware.devtype)

    • +

  • Other client-specific metadata

    • +
+

Packages

+

A package is any file that can be used by a compatible update client to update the running system. +From the server’s point of view, update packages are simple binary blobs and no specific structure is enforced. +Each package has metadata assigned to it that indicates its contents. +The following metadata fields are mandatory for all packages:

+
    +

  • Software version (rdfm.software.version) - indicates the version of the contained software

    • +

  • Device type (rdfm.hardware.devtype) - indicates the device type a package is compatible with

    • +
+

The device type is used as the first filter when searching for a compatible update package. +Any package that does not match the device type reported by the update client will be considered incompatible.

+

A package may also contain metadata with requires: clauses. +The requires clause is used to indicate dependencies on certain metadata properties of the device. +In its most basic form, it can be used to indicate a dependency on a certain system image to be installed for proper delta update installation. +For more complex use cases involving many intermediate update steps, it can also be used to enforce an order in which certain packages must be installed.

+

Groups

+

A group consists of many assigned devices. Each group can also be assigned one or many packages. +The group itself also contains metadata about the group name, description, update policy, and other arbitrary information which can be used by custom frontends interacting with the server.

+

Update policy

+

An update policy defines the target version the devices within a given group will be updated to. +The policy is a string with the syntax <policy>,[arguments]. +Required arguments depend on the specific policy being used. +Currently, the following policies are supported:

+
    +

  • no_update (default) - requires no arguments, the server will treat all devices within the group as up-to-date, and will not return any packages to devices requesting an update check. This is the default update policy for all newly created groups.

    • +

  • exact_match - specifies that the server will attempt to install the target software version on each of the devices in the group. +Example usage: exact_match,version1 - this specifies that the server will attempt to bring all of the devices to the software version version1. +This process may involve installing many intermediate packages, but the end result is a device that’s running the specified version. +The server will use group-assigned packages when resolving the dependency graph required for reaching the target version.

    • +
+

Update resolution

+

When resolving a path to the correct target version, the server utilizes only the group-assigned packages. +When a device is requesting an update check, a package dependency graph is created. +The edges of the graph correspond to different packages available during the update process (which are compatible with the device, as indicated by the rdfm.hardware.devtype field), while the nodes indicate the software versions (as indicated by the rdfm.software.version fields of each package). +Next, the group’s update policy is queried, which indicates the target version/node each device should be attempting to reach. +The shortest path between the currently running node and the target node is used as instructions for how the server should lead the device to the specified version.

+

Example scenario: simple update assignment

+

Consider a group with the following packages assigned:

+
    +

  • P0 - devtype=foo, version=v1

    • +

  • P1 - devtype=bar, version=v2

    • +

  • P2 - devtype=baz, version=v3

    • +
+

The group is specified to update to version v3 per the policy. Devices are reporting the following metadata:

+
    +

  • D0 - devtype=foo, version=v3

    • +

  • D1 - devtype=bar, version=v3

    • +

  • D2 - devtype=baz, version=v3

    • +
+

In this scenario, devices D0 and D1 shall receive the update packages P0 and P1 respectively. +The device D2 is considered up-to-date, as its version matches the target specified in the group policy.

+

Example scenario: downgrades

+

Consider a group with the following packages assigned:

+
    +

  • P0 - devtype=foo, version=v4

    • +
+

The group is specified to update to version v4 per the policy. Devices are reporting the following metadata:

+
    +

  • D0 - devtype=foo, version=v5

    • +
+

In this scenario, the device D0 will receive the package P0 to be installed next.

+

Example scenario: sequential updates

+

Consider a group with the following packages assigned:

+
    +

  • P0 - devtype=foo, version=v2, requires:version=v1

    • +

  • P1 - devtype=foo, version=v3, requires:version=v2

    • +
+

The group is specified to update to version v3 per the policy. Devices are reporting the following metadata:

+
    +

  • D0 - devtype=foo, version=v1

    • +
+

In this scenario, the device D0 will first be updated to the package P0, as it’s the only package that is compatible (matching device type and different version than the one running on the device). +The package’s only requires clause also matches against the device’s metadata.

+

After successful installation, during the next update check on the newly installed version (v1), the device will receive the next available package. +As the device is now reporting a version field of v1 and the package’s requires: clause passes, package P1 becomes the next candidate package available for installation. +After successful instalation of P1, no more packages are available and the device is considered to be up-to-date.

+

Example scenario: delta updatess

+

Consider a group with the following packages assigned:

+
    +

  • P0 (delta) - devtype=foo, version=v5, rootfs=e6e2531.., requires:version=v0, requires:rootfs=2f646ac..

    • +

  • P1 (delta) - devtype=foo, version=v5, rootfs=e6e2531.., requires:version=v2, requires:rootfs=6d9aee4..

    • +
+

The group is specified to update to version v5 per the policy. Devices are reporting the following metadata:

+
    +

  • D0 - devtype=foo, version=v0, rootfs=2f646ac..

    • +

  • D1 - devtype=foo, version=v2, rootfs=6d9aee4..

    • +
+

In this scenario, devices D0 and D1 will receive packages P0 and P1 as updates respectively. +The packages themselves contain different binary contents, in this case a delta between a given base version’s system partition (v0 and v2) and the target (v5), but the end result is an identical system on both devices. +This way, many delta packages may be provided for updating a fleet consisting of a wide range of running versions.

Server Integration flows

+

This chapter describes the various integration flows between device clients and the RDFM Management server.

+

Device authentication

+

At the start of their execution, all RDFM-compatible device clients shall authenticate with the server. +This shall be done by utilizing the /api/v1/auth/device endpoint. +For details on the request schema, refer to the Server API Reference chapter. +An example request made to this endpoint is shown below:

+
{
+    "metadata": {
+        "rdfm.hardware.devtype": "device-type",
+        "rdfm.software.version": "foo",
+        "rdfm.hardware.macaddr": "00:11:22:33:44:55",
+    }
+    "public_key": "<RSA public key of the device in PEM format>",
+    "timestamp": 1694681536,
+}
+
+
+

The JSON payload bytes must be signed by the device client with its securely stored RSA private key using PKCS #1 v1.5 signature with SHA-256 digest (function RSASSA-PKCS1-V1_5-SIGN defined in RFC 8017) +The calculated signature must then be attached, encoded as base64, to the authorization request in the header X-RDFM-Device-Signature. +If the server successfully validates the attached signature, the device will be registered in the server’s database, if it wasn’t previously registered already. +The device-specified MAC address is used as a unique identifier for this specific device.

+

Before the device is authorized to access the RDFM API, it must be accepted first by an administrative entity interacting via a separate API with the RDFM server. +If the device was not accepted, or its acceptation status was revoked, the above request shall fail with the 401 Unauthorized HTTP status code. The device client must handle this status code gracefully, for example by retrying the attempted request after a certain time has passed.

+

Once the device is accepted into the RDFM server, the above request shall return a device-specific app token, that can be used to interact with device-side API endpoints. +The app token is not permanent, and will expire after a certain time period. +The device client must not make any assumptions about the length of the usability period, and instead should take a defensive approach to any requests made to the device-side API and reauthenticate when a response with the 401 status code is received.

+

Device update check

+

Once authorized, a device client will have access to the device-side API of the RDFM server. +The device client is expected to regularly poll for updates by utilizing the /api/v1/update/check endpoint.

+

In the update check request, the device client must provide all of its local metadata. +The metadata, which consists of simple key/value pairs, uniquely describes the set of software and/or hardware present on the device, but may also represent other transient +properties not persisted in storage, such as temperature sensor values.

+

When making the update check, the device client is advised to provide all of its metadata to the server in the update request. +At the time of writing, below three metadata properties are mandatory and must be present in all update checks:

+
    +

  • rdfm.software.version - version identifier of the currently running software package

    • +

  • rdfm.hardware.devtype - device type, used for limiting package compatibility only to a subset of devices

    • +

  • rdfm.hardware.macaddr - MAC address of the device’s main network interface

    • +
+

For future compatibility, device clients are advised to provide all of their metadata, not only the mandatory keys, in the update check request. +For more details on the structure of an update check request, consult the Update API Reference

+

When a new package is available, the response shall be as described in the API Reference, and a one-time download URL to the package is generated. +The device client shall use this URL to download and install, or in the case of clients capable of stream installation, directly install the package. +The device client MUST verify the hash of the package as described in the update check response.

+

Additionally, the device client MUST verify whether the package contents look sane before attempting to install it. +The server shall never return a package that is not of the same device type as the one advertised by the client. +However, the server itself currently imposes no limitations on the binary contents of the packages themselves.

+

Management WebSocket

+

If supported, the device may also connect to a device management WebSocket. +This provides additional management functionality of registered devices, such as reverse shell and file transfer. +To connect to the WebSocket, a device token is required to be provided in the Authorization header of the WebSocket handshake. +The format of the header is exactly the same as in other device routes and is described in the API Reference chapter.

+

The general management flow is as follows:

+
    +

  1. Device connects to the management WebSocket: /api/v1/devices/ws

    2. +

  2. Device sends a CapabilityReport message indicating the capabilities it supports

    3. +

  3. Device reads incoming management messages from the server and handles them accordingly

    4. +

  4. Device may also send messages to the server to notify of certain situations

    5. +
+

RDFM Management Protocol

+

The management protocol is message-oriented and all messages are expected to be sent in WebSocket text mode. +Each message is a JSON object in the form:

+
{
+    "method": "<method_name>",
+    "arg0": "...",
+    "arg1": {"...": "..."},
+    "...": "..."
+}
+
+
+

The type of message sent is identified by the method field. +The rest of the object fields are unspecified and depend on the specific message type. +Schema for messages used by the server can be found in common/communication/src/request_models.py. +On error during handling of a request, the server may return a custom WebSocket status code. +A list of status codes used by the server can be found in common/communication/src/rdfm/ws.py.

+

Capabilities

+

A capability indicates what management functionality is supported by a device. +The device should report its capabilities using the CapabilityReport message immediately after connecting to the server. +By default it is assumed that the device does not provide any capabilities.

+

Capability - shell

+

This capability indicates that a device supports spawning a reverse shell. +The following methods must be supported by the device:

+
    +

  • shell_attach

    • +
+

A device with the shell capability should react to shell_attach messages by connecting to a shell WebSocket at /api/v1/devices/<shell_attach.mac_addr>/shell/attach/<shell_attach.uuid>. +This establishes a connection between the requesting manager and the device. +This WebSocket can then be used to stream the contents of the shell session and receive user input. +The format of messages sent over this endpoint is implementation defined. +However, generally the shell output/input are simply sent as binary WebSocket messages containing the standard output/input as raw bytes.

System Architecture

+

The reference architecture of an RDFM system consists of:

+
    +

  • RDFM Management Server - handles device connections, packages, deployment, remote device management

    • +

  • Devices - devices connect to a central management server and utilize the exposed REST API and device-server RDFM protocol for providing remote management functionality

    • +

  • Users - individual users that are authenticated and allowed read-only/read-write access to resources exposed by the server

    • +
+

The system architecture can be visualized as follows:

+
+Architecture summary +
+

Figure 1 +Summary of the system architecture

+
+

HTTP REST API

+

For functionality not requiring a persistent connection, the server exposes an HTTP API. A complete list of available endpoints can be found +in the RDFM Server API Reference chapter. The clients use this API to perform update checks.

+

Device-server RDFM Protocol

+

The devices also maintain a persistent connection to the RDFM Management Server by utilizing JSON-based messages sent over a WebSocket route. +This is used to securely expose additional management functionality without directly exposing device ports to the Internet.

+

Each message sent using the RDFM protocol is structured as follows:

+
0                            h
++----------------------------+
+| utf-8 encoded JSON message |
++----------------------------+
+
+
+

The message is a UTF-8 encoded JSON object, where each message is distinguished by the mandatory 'method' field.

+

An example request sent to the server may look like:

+

{'method': 'capability_report', 'capabilities': {'shell': True}}

+

A response from the server may look like:

+

{'method': 'alert', 'alert': {'devices': ['d1', 'd2']}}
