Socket.IO Client is a real-time WebSocket client library that establishes persistent bidirectional connections to a server, with automatic fallback to HTTP long-polling when WebSocket connections are unavailable. It provides an event-based bidirectional messaging framework where clients and servers exchange named events with serializable data, supporting acknowledgements and timeouts for reliable communication. The client distinguishes itself through automatic reconnection with exponential backoff, maintaining connection reliability by monitoring health and reconnecting with increasing delays
Partitions a single connection into isolated logical namespaces for separating application logic and authorization boundaries.
Bubblewrap is a Linux sandbox runner that creates lightweight, isolated execution environments for running untrusted applications. It combines Linux user, mount, network, PID, and UTS namespaces with seccomp-BPF system call filtering to restrict filesystem, network, process, and inter-process communication access. The project provides comprehensive process isolation by giving each sandbox its own private tmpfs root with selective bind-mounts, a separate network stack containing only a loopback interface, an independent process ID space, and remapped user and group identifiers. It applies secc

CRI-O is an open-source container runtime that implements the Kubernetes Container Runtime Interface (CRI) to manage container images, pods, and containers on cluster nodes using OCI-compatible runtimes. It serves as a node-level container manager that handles image pulling, container lifecycle, and resource monitoring for Kubernetes clusters, running containers according to the Open Container Initiative specifications. The runtime distinguishes itself through live configuration reloading that applies changes to runtime definitions, registry mirrors, and TLS certificates without restarting th
Skips the infra container when pod-level PID namespace is not requested, as an experimental feature.
Try ist ein Werkzeug zur Verwaltung ephemerer Shell-Umgebungen und zur Ausführung von Befehlen innerhalb einer isolierten Sandbox. Es nutzt OverlayFS und Linux-Namespaces, um zu verhindern, dass Prozesse das Live-System verändern, und fungiert sowohl als Befehls-Sandbox als auch als Auditor für Dateisystemänderungen. Das Projekt ermöglicht es Benutzern, Dateimodifikationen in einer temporären Schicht zu erfassen und diese Änderungen zu inspizieren, bevor entschieden wird, ob sie angewendet oder verworfen werden sollen. Es unterstützt einen Workflow des Auditings von Ergänzungen und Modifikationen, um verifizierte Änderungen anschließend wieder in das Host-Dateisystem zusammenzuführen. Das Tool bietet Funktionen für interaktive Sandbox-Shells, Verwaltung benutzerdefinierter Sandbox-Verzeichnisse und die Möglichkeit, mehrere Overlay-Verzeichnisse in einer einzigen geschichteten Umgebung zusammenzuführen. Es enthält zudem Shell-Completion-Skripte für Befehls- und Flag-Autovervollständigung.
Provides a sandbox that uses Linux namespaces and OverlayFS to execute commands without altering the host system.
Tetragon ist ein auf eBPF basierendes Toolset für Laufzeitsicherheit und Observability, das für Linux- und Kubernetes-Umgebungen entwickelt wurde. Es fungiert als Security-Policy-Manager, Observability-Agent und Enforcement-Engine, die sich in Kernel-Funktionen und Tracepoints einklinkt, um Privilegieneskalationen, Container-Ausbrüche und unbefugte Systemaktivitäten zu erkennen. Das Projekt zeichnet sich durch seine Fähigkeit zur Echtzeit-Durchsetzung auf Kernel-Ebene aus, wodurch bösartige Prozesse synchron beendet oder Rückgabewerte von Funktionen noch vor Abschluss eines Systemaufrufs modifiziert werden können. Es bietet eine tiefe Kubernetes-Integration durch die Synchronisierung von Container-Identitäten und die direkte Zuordnung von Low-Level-Kernel-Ereignissen zu Pods und Namespaces. Die weiteren Funktionen umfassen eine umfassende Systemaufruf-Prüfung (Auditing), die Verfolgung von Netzwerkverbindungen und die Überwachung der Dateiintegrität. Das System unterstützt ein dynamisches Policy-Management und bietet Diagnosetools zur Überwachung der BPF-Performance und Ressourcennutzung. Das Deployment wird in Kubernetes-Clustern über Helm-Charts sowie durch eigenständige Container und native Betriebssystempakete unterstützt.
Tracks Linux namespace operations to detect when processes attempt to switch namespaces.
Pouch ist eine Linux-Container-Runtime und eine OCI-Container-Engine, die für die Ausführung containerisierter Anwendungen entwickelt wurde. Sie fungiert als Kubernetes-Container-Runtime und integriert sich in Orchestratoren, um den Lebenszyklus von Pods und isolierten Anwendungsumgebungen zu verwalten. Das Projekt bietet ein Peer-to-Peer-Image-Verteilungssystem, um große Container-Images über große Cluster hinweg bereitzustellen und gleichzeitig die Bandbreitenlast zu reduzieren. Es bietet zudem Unterstützung für ältere Linux-Kernel-Versionen, wodurch moderne Container-Runtimes die Kompatibilität mit älterer Hardware aufrechterhalten können. Die Runtime implementiert Anwendungsisolierung mithilfe von Hypervisor-basierten Sandboxes und Kernel-Level-Ressourcenisolierung. Ihre Architektur umfasst ein geschichtetes Dateisystem-Overlay und ein Shim-basiertes Lifecycle-Management-System, das die Kompatibilität mit Open-Container-Initiative-Image- und Runtime-Spezifikationen sicherstellt.

Modifies execution environments using kernel namespaces to hide processes or isolate applications.
The project provides an open container runtime specification and standardized schema for defining container configurations, namespaces, resource limits, security policies, and filesystem mounts across platforms. It outlines the formal configuration formats, lifecycle operations, and execution environments necessary for portable, isolated container workloads.

CRIU is a Linux process checkpointing tool and state manager used to freeze running applications and save their memory and state to disk for later restoration. It functions as a container migration engine and an OCI checkpoint image converter, allowing the live state of running containers to be transferred between different hosts. The project distinguishes itself through its ability to persist network connectivity, acting as a TCP connection state persister that saves and reconstructs network socket states to maintain active communication after a restart. It further enables the distribution o
