This is a fork of Node.js project adapted to be used with KasperskyOS. For more information about the target OS, please refer to KasperskyOS Community Edition Online Help.
Please note, that to be able to develop your own NodeJS application with KasperskyOS you'd need to build OS principles understanding (see mention link for examples, API and so on).
For general information on using Node.js, its features and so on, please see the Node.js website.
Please refer to the original Node.js (parent) README.md for more details not related to this fork.
How to build (on Linux host)In order to build the code successfully, you'll need to install KasperskyOS Community Edition SDK on your system. The latest version of the SDK can be downloaded from this link.
All of the files required to build a web interpreter with KasperskyOS, and some examples of how you can bridge it with your solution, are located in the folder:
Please note that the minimum required version of KasperskyOS Community Edition SDK is 1.2. The recent SDK release could be downloaded from the project official page.
Once you have cloned git repository with project sources and satisfied all the requirements listed in Building Node.js, KasperskyOS-specific build is performed as follows:
./kos.<KasperskyOS SDK root>/toolchain/bin to your PATH environment variable.make configure to do actual project config (this is a wrapper for ./configure with a pre-defined arguments list).make compile -j XX (select number of threads XX according to your system's HW performance).Once you have the NodeJS build completed it is time to prepare your own Solution with using the NodeJS and some custom JS-script. In order to do that there are some files prepared at the kos/image_builder directory already, and all you need to do is to invoke following command (staying at the kos folder):
SDK_VERSION=<KasperskyOS SDK version> make helloworld
This will build KasperskyOS image for Qemu and run very simple Hello-World example, which is a very simple test to make sure that binary you've just built actually works (this command will also build KasperskyOS romfs image and so on). Please, note that make helloworld command will run qemu-system-aarch64 from SDK and will, eventually, run KasperskyOS-image under emulator control.
Note: specifying SDK_VERSION is only necessary when <KasperskyOS SDK root> contains SDK which number differs from what is assigned in make-vars.mk (see Directory structure section below).
It is also possible to run NodeJS as part of KasperskyOS-based user solution on the Raspberry Pi 4B board. Further instructions describe the way to build and run hello world NodeJS application.
First of all it is advised to prepare bootable flash-card following instruction from the KasperskyOS Community Edition Online Help or using either Raspberry Pi Imager or grab & flash pre-build board image, which could be found here
As the Raspberry Pi has no u-boot shipped with image, it is required to prepare one for you specific board and update board boot configuration to start u-boot binary instead of default RaspbianOS kernel (see guide from the KasperskyOS Community Edition Online Help or do your own setup).
Then, the easiest way to prepare KasperskyOS image to run on hardware is invoke following commands:
make qemubuild
make helloworld FOR_HW=1
And eventually, copy the kos/image_builder/build-arm64/einit/kos-image file to the first partition of the flash-card. Then plug it (sd-card) in, power-up the board and have fun.
The explicit way to build NodeJS with hello world application is
make qemubuild
make realhw NODE_ARG="/opt/node/test/message/hello_world.js"
You can find all the applications in the directory: kos/image_builder/build-arm64/rootfs/root/opt/node/test
If you still need some hint how to run it using u-boot, so here is the commands, assuming that your boot partition is formatted to FAT32.
fatload mmc 0 ${loadaddr} kos-image
bootelf ${loadaddr} ${fdt_addr}
So the solution will start.
Makefile - main Makefile to configure & build Node.js project for KasperskyOS. Use make help target to see available options & usage guidelines.add-ons - example hello add-on along with its build fixtures.image_builder - sources and CMake-based build system for KasperskyOS images along with build output files.
build-<arch> - architecture-specific KasperskyOS build artifacts.einit, env, klog_storage - sources and CMake build rules for corresponding entities.node - CMake build rules for Node.js itself.resources - description files for all the entities.
certs - TLS-related stuff.edl - entities *.edl description filesramfs - additional files to be added to the KasperskyOS image filesystems.CMakeLists.txt - project-level CMake build rules.rules - build rules for the aarch64 Node.js customized project (all the files from this folder are included into main Makefile, see above).
make-images.mk - a set of rules to build KasperskyOS images.make-vars.mk - declaration of variables to control build rules.make-run-tests.mk- a set of rules to run KasperskyOS test images.make-debug.mk - a set of debug-enabled build targets.IPv6 is not yet supported at the moment, as it's not available in KasperskyOS for now.OpenSSL CLI (since it needs to start a separate process(es) in runtime).process.getuid() isn't supported (corresponding KasperskyOS API calls getuid/geteuid always return 0).fs.watch() isn't supported (returns ENOSYS in KasperskyOS).Socket.addSourceSpecificMembership() isn't supported (returns ENOSYS in KasperskyOS).fs.utimesSync() isn't supported (utime returns ENOSYS in KasperskyOS).process.cpuUsage() and process.resourceUsage() aren't supported (return ENOSYS in KasperskyOS).process.kill() isn't supported (returns ENOSYS in KasperskyOS due to limitation of inter-process communication).Node.js inspector (V8 inspector, profiler and sampler) isn't fully supported (due to KasperskyOS signals implementation restrictions).Unhandled Page Fault).QEMU option -smp 1) aren't supported.AF_UNIX/AF_LOCAL) are not bindable. is an empty string).getaddrinfo failures (returns EAI_AGAIN or ENOTFOUND) on Raspberry Pi 4B target (for instance test-async-exec-resource-http.js);test-async-local-storage-promises.js);test-esm-loader-thenable.mjs): 2 minutes per test isn't enough for real HW every now and then, even though typical test takes roughly 1 minute.In order to be able to run Node.js tests for KasperskyOS, its configuration and build have to be done using the following commands (from <project repository root>/kos folder):
make configure CFLAGS=-DKOS_NODE_TEST=1 CXXFLAGS=-DKOS_NODE_TEST=1 make compile -j XX CFLAGS=-DKOS_NODE_TEST=1 CXXFLAGS=-DKOS_NODE_TEST=1 python -m pip install pandas psutil
The latter one installs pandas and psutil Python modules for the current user (depending on Linux distribution being used this command might require python-is-python3 package to have been installed).
After the build has completed all the tests can be run with:
make tests options="-j XX --test-root=../test -t 120"
Again, the number of threads XX depends on your system's HW performance.
Please also note: tests are being run via QEMU with -smp 4 option thus allowing each thread to spawn 3 others (even though it might not be the case for the particular QEMU simulation running Node.js test(s)).
Alternatively, one may wish to run a specific test as follows:
make tests options="-j XX --logfile test.log --test-root=../test --filter-test=<path to the test .js file> -t 120"
Path to .js file is relative to the folder specified as --test-root. --filter-test parameter allows specifying several (comma-separated) .js files with tests as well as a (relative) path to a folder containing .js files (i.e. parallel/).
There are three tested demo projects on the TotalJS platform:
To run these demos, firstly you need to build NodeJS according to the instructions.
Then it's necessary to clone these three demo repositories into a free folder:
git clone https://github.com/totaljs/cms git clone https://github.com/totaljs/files git clone https://github.com/totaljs/messenger
To automatically install dependencies for demo projects, you should have npmjs pre-installed on the host system.
After cloning the repositories, you need to go to the folder with the desired demo project and run:
It is also necessary to uncomment the line: options.port = parseInt(process.argv[2]) in the files cms\index.js, files\index.js, messenger\release.js.
To start the CMS and File Manager demos it is required to run the following command:
make run NODE_ARG="/demo/index.js;\"8080\";--release" NODE_PORT=1234 QEMU_NET=1 NODE_DEMO=1 DEMO_PATH=<path to demo>
DEMO_PATH - path to the demo directory.
To run the Messenger demo project, run the following command:
make run NODE_ARG="/demo/release.js;\"8080\";--release" NODE_PORT=1234 QEMU_NET=1 NODE_DEMO=1 DEMO_PATH=<path to demo>
Running demos will be available from the browser at http://localhost:1234/. The port can be configured through a variable NODE_PORT.
It is not recommended to change port 8080 as QEMU is configured to only forward from this port to the port specified in NODE_PORT.
Following list of built-in third-party subprojects which were changed with respect to enabling KasperskyOS support:
Please see the CONTRIBUTING.md page for generic info.
We'll follow the parent project contributing rules but would consider to accept only KasperskyOS-specific changes, so for that it is advised to use pull-requests.
