Building Event-Driven WebAssembly on Kubernetes: Runtime, Observability, and Security - Brandon Kang, Akamai Technologies & Nam Hai, Hylatek JSC

Tuesday August 11, 2026 11:00 - 11:30 KST

Orchid 2

As cloud native systems evolve, WebAssembly(WASM) is emerging as a runtime that complements and sometimes challenges container based approaches. With fast startup, strong isolation, and portability, WASM enables efficient and secure event driven workloads.

In this session, we explore how to build and run the systems using WebAssembly on Kubernetes, focusing on SpinKube, an open source project that brings WASM workloads into Kubernetes.

Through a live demonstration, we will deploy and run WASM workloads using SpinKube, highlighting real workflows. We will also compare cold start and execution performance, showing millisecond startup and lower latency than traditional containers. Plus to demonstrate observability using eBPF based telemetry, we enable visibility into runtime behavior without overhead. Attendees will learn how to trace execution, monitor performance, and troubleshoot distributed WASM systems.

Finally, we will talk how WebAssembly improves security and operational efficiency by reducing the attack surface and enabling consistent execution across environments, providing a practical guide for production adoption.

Upstream Kernel Hardening: Recent Progress and Challenges - Gustavo A. R. Silva, Linux Kernel Self-Protection Project

Tuesday August 11, 2026 11:00 - 11:30 KST

Orchid 1

With the release of Linux 7.0, Rust is no longer considered experimental. New and safer components are expected to be written in Rust in the near future. However, the Linux kernel still contains more than 35 million lines of code written in C. This code will remain critical for years to come and, for the benefit of everyone, must continue to be maintained, improved, and hardened where possible.

In the Linux Kernel Self-Protection Project, we care deeply about this, and we've been advancing kernel hardening upstream for several years. In this presentation, we'll review recent hardening efforts and discuss the challenges we continue to face as we work toward our ultimate goal of eliminating classes of bugs and methods of exploitation in the upstream Linux kernel.

SBOMs Aren't Enough. Secure Your Software Supply Chain End-To-End - Yongjae Chung, New York University Secure Systems Lab & Justin Cappos, New York University

Tuesday August 11, 2026 11:00 - 11:30 KST

Magnolia

You probably heard that SBOMs are helpful, but did you know that an SBOM only addresses a fraction of what can go wrong in your software supply chain? The SLSA (Supply Chain Levels for Software Artifacts) specification identifies 9 distinct threat areas, spanning from source code, all the way to package distribution. Most development teams address one or two of these and call it a day, leaving gaps that real-world attacks like SolarWinds and Log4J have already exploited. We understand that it is difficult to cover all aspects when it comes to the software supply chain.

How about we make this much easier? In this talk, we will present an overview of the modern software supply chain threat model, and show how you can provide integrity throughout the whole process of your software development life cycle. We will introduce an easy-to-setup, end-to-end open source stack, built from frameworks and tools within the CNCF/OpenSSF ecosystem.

Self-Healing Rollouts: Automating Production Fixes With Agentic AI - Kevin Dubois, IBM

Tuesday August 11, 2026 11:40 - 12:10 KST

Orchid 2

Your software rollouts to production are probably always flawless, right? For the rest of us, once in a while we do run into issues when releasing code to production. Even with robust CI/CD, production rollouts can hit unexpected snags. While in Kubernetes, ArgoCD and Argo Rollouts excels at Progressive Delivery and automated rollbacks to mitigate deployment issues, what if we could go a step further?

This session explores how to elevate your release process by integrating Agentic AI and asynchronous coding agents, with Argo Rollouts canary deployments. We'll demonstrate how an intelligent agent can automatically analyze a rollout failure, pinpointing the root cause. Beyond diagnosis, these agents can take proactive steps on your behalf, suggesting and even implementing code fixes as new pull requests, which can be redeployed automatically after PR review. This approach moves us closer to truly self-healing deployments.

Join us to learn how to combine the power of cloud native projects like Kubernetes, ArgoCD and Argo Rollouts with the autonomous capabilities of Agentic AI, achieving a release experience that is not only seamless but also resilient.

One Binary, Every Package Manager: Shipping a Rust CLI To PyPI, Npm, Homebrew, Winget, and Beyond - Ajit Kumar, Wellmatix

Tuesday August 11, 2026 11:40 - 12:10 KST

Magnolia

Most dev tools die in obscurity because installation friction kills adoption before the first command is run. This talk provides a battle-tested playbook for solving that problem using evnx—a Rust CLI for validating and secret-scanning `.env "files"—as a real-world case study.

Launched in early 2026, evnx achieved thousands of cross-ecosystem downloads within weeks by treating distribution as a first-class engineering concern. The session breaks down a complete distribution matrix:

Registry Packaging: Using crates.io as a source of truth, Maturin for native Python wheels, and npm wrappers for platform-specific binaries.
OS Package Managers: Automating Homebrew formulas via cargo-dist, plus Scoop and Winget submissions.
Developer Integration: GitHub Actions with SARIF output, pre-commit hooks, and lightweight Docker CI images.
Supply-Chain Security: Leveraging PyPI Trusted Publishing (OIDC), provenance attestations, and cosign for signed containers.

Attendees will receive reusable GitHub Actions workflows and manifest templates from the public evnx repo to ship any Rust CLI across ecosystems without sacrificing security or maintainer sanity.

Beyond Round-Robin: GPU-Aware Load Balancing for LLM Inference in Kubernetes - Seokhwan Kong, NETLOX

Tuesday August 11, 2026 13:35 - 14:05 KST

Orchid 2

Standard load balancers route LLM requests without awareness of KV-cache state or GPU queue depth — causing inflated Time-To-First-Token and wasted accelerator capacity.

loxilb closes this gap with an eBPF-native AI gateway. The L4 layer uses XDP/TC and kernel sockmap for zero-copy forwarding. The L7 layer adds API-key validation, token-quota enforcement, and accelerator-aware routing via Consistent Hashing with Bounded Loads (CHWBL).

This talk focuses on KV-exact routing for P/D disaggregated deployments. When requests share a prompt prefix, prefill GPUs recompute identical KV tensors repeatedly — wasting up to 80% of GPU cycles. Tier 1.5 eliminates this: loxilb tokenizes the prompt in-process (HuggingFace Rust tokenizer via CGO), computes block hashes matching vLLM's internal format, and routes to the exact GPU already holding those KV blocks — via a live inventory fed by vLLM's native ZMQ event stream.

Unlike serving-layer schedulers (llm-d, Dynamo), this runs in the eBPF data-plane hot path with no Kubernetes dependency — works on bare metal, VMs, and BlueField DPUs.

We'll trace a live request through the P/D testbed and share lessons from building GPU-state-aware routing

Science in the Agentic Era: Structured Experimentation With Ado - Alessandro Pomponio, IBM

Tuesday August 11, 2026 13:35 - 14:05 KST

Grand Ballroom 2-3

As AI agents become increasingly capable of generating code and executing complex workflows, their use in research is still limited by concerns about rigour and reproducibility. This session introduces ado, an open-source framework that brings structure to agent-driven scientific experimentation.

ado defines schemas for the core elements of a discovery process: the problem space and how to explore it. Agents iteratively propose and refine experimental campaigns as validated configurations based on these schemas, while ado handles execution. This separation of research intent from execution constrains agents to focus on the research task, reducing hallucinations and the need to write boilerplate code. Combined with a set of agent skills for formulating problems, creating and running experiments, and analysing their results, ado provides a framework for end-to-end agent-driven discovery workflows.

Whether you are an experienced researcher or new to computational experimentation, this talk presents a practical model for integrating AI agents into research workflows while keeping experimentation structured, transparent, and reproducible.

Sponsored Session: Trust by Design: Engineering Reliable Enterprise AI Workflows with Open Source - KyoSeok Kim & Suyeon Woo, IBM

Tuesday August 11, 2026 13:35 - 14:05 KST

Rose

When enterprises bring AI into real-world operations, reliability challenges extend far beyond hallucinations and response accuracy. Document structure and meaning can be lost during processing, retrieval may fail to provide sufficient grounding, and models may violate business rules or operational constraints. As agents connect to enterprise systems, additional risks emerge, including unauthorized tool calls and actions that are difficult to trace or audit.
These challenges cannot be addressed by adding a guardrail at the final stage. Reliability must be designed across the entire workflow, from document understanding and retrieval to reasoning, generation, and execution.
This session presents an open-source reference architecture that combines document representation with Docling and DocLang, grounded retrieval and reasoning with OpenRAG and Granite, requirement-driven generation and validation with Mellea, and controlled, observable tool integration with ContextForge.

LLMs Change — Where Should Knowledge Live? (Lessons From SBOM) - Koji Annoura, Annoura Office

Tuesday August 11, 2026 14:15 - 14:45 KST

Rose

Large Language Models (LLMs) are widely used to search, summarize, and generate answers. They are powerful, but results are not always stable and can be difficult to verify.

Many systems use Retrieval-Augmented Generation (RAG) to connect LLMs with external data. This helps, but does not fully solve the problem. The same question can produce different answers depending on the model or context, making knowledge hard to manage.

This raises a simple question: where should knowledge be managed?

A similar issue exists in software supply chains. SBOM (Software Bill of Materials) makes components and relationships visible, but is often treated as static data.

Based on hands-on experience designing graph-based knowledge systems, this session introduces a design approach: managing knowledge outside LLMs as structured, persistent data.

We discuss lessons from SBOM and how graph-based approaches—using technologies such as SQL/PGQ or GQL—can help understand relationships and trace changes.

The focus is a practical way of thinking for more open and sustainable knowledge practices.

The Era of Vibe Coding: Why High-Skill Engineers Are More Critical Than Ever - Yongjin Lee, Songnae High-school

Tuesday August 11, 2026 14:15 - 14:45 KST

Grand Ballroom 2-3

"Let’s be real: My AI has dementia."
"Vibe-coding in real: Me and My AI is stupid"
Welcome to the "Vibe Coding" era, where anyone can prompt their way to complex code. But as a 17-year-old developer who "bullied" LLMs to build a custom Linux Based OS (MaruxOS) from scratch, I’ve seen the ugly truth: AI is a brilliant assistant, but a chronic liar with a 5-minute memory.
In this session, I expose the messy reality of AI-native development. I’ll share how I battled "Contextual Dementia"—where AI forgets my ARM64 architecture mid-patch—and survived "Mindless Yes-Clicking Syndrome," where a single trusted prompt almost nuked my entire glibc.
Key Takeaways:
The Hallucination Hunter: Sniffing out AI’s "confident bullshit."
The Dementia Doctor: Managing AI’s memory loss to maintain architectural integrity.
The Final Decider: Moving beyond the "Yes-Clicking" trap to take true technical ownership.
AI might be writing the code, but only a real engineer can stop it from burning the house down.

From Contribution To Culture: 14 Years of Building an OSPO That Outgrew Itself - Darae Ahn, Samsung Electronics

Tuesday August 11, 2026 14:15 - 14:45 KST

Magnolia

Over the past decade, many organizations have established OSPOs to manage open source usage and compliance. However, building a sustainable open source culture requires more than policies and processes.

This session shares a 14-year journey of an OSPO that evolved from a contribution-focused group into a broader organization encompassing usage, compliance, and internal enablement.

It explores how open source practices were embedded into engineering culture through project incubation, developer engagement, and internal leadership programs. Over time, these efforts led to a shift where open source activities became self-sustaining, with teams proactively initiating projects and contributions.

The session also reflects on an unexpected outcome: talent mobility. As internal open source leaders grew, many moved on to new opportunities, revealing both retention challenges and the broader impact of cultivating open talent.

Key lessons include the balance between control and autonomy, the role of leadership in cultural change, and how open source can be viewed not only as a compliance requirement, but as a long-term investment in culture and organizational brand.

The Butterfly Effect of a Broken Disk: Top-Down Ceph Troubleshooting To Upstream Contribution - Sangyun Lee, CJ OliveNetworks

Tuesday August 11, 2026 14:55 - 15:25 KST

Orchid 2

Tech blogs usually talk about huge Ceph clusters with thousands of disks. But in reality, many of us run smaller on-prem setups. I will share my real experience of debugging a small Ceph cluster (10 nodes, 10 NVMe, 15 normal SSDs) and how tracking a slow app led me to write an upstream C++ patch.

It started when our Valkey (Redis) pods suffered from severe write latency. We checked CephFS metadata and Istio network metrics, but they were fine. So we dug into the storage layer using ceph osd perf. We saw huge latency on one specific node. Looking at the kernel logs (dmesg -k), we found a failing NVMe disk. I will explain the "Slow OSD" issue—how one broken disk can freeze a 3-replication cluster.

During this outage, reading ceph osd perf was very frustrating because the OSD IDs were completely unordered. Since it made debugging harder, I decided to fix it. I looked into Ceph's C++ code, changed the unordered hash map to a sorted vector (std::sort), and opened PR #67915 (https://github.com/ceph/ceph/pull/67915). I will share my experience discussing the fix with Ceph maintainers and why I believe engineers should fix the open-source tools they use.

From Black Box To Insight: Observability for AI Agents in Production - Mostafa Radwan, Datadog & Brandon Kang, Akamai Technologies

Tuesday August 11, 2026 14:55 - 15:25 KST

Rose

AI agents are quickly moving from prototypes to production systems that manage APIs, tools, and complex reasoning tasks.

Once these systems are deployed, they often act like black boxes, hiding failures, slowdowns, and unexpected behavior.

This session will show you how to add observability to agentic systems with open-source tools and cloud-native tech.

Brandon and Mostafa will break down the lifecycle of an AI agent, covering prompt execution, tool invocation, memory access, and multi-agent coordination, and demonstrate how to make each stage observable.

Using a practical, architecture-focused approach, they will show how to:

- Trace agent workflows across distributed systems
- Monitor latency and token usage
- Detect anomalies such as hallucinations, tool misuse, and runaway behavior.
- Connect LLM behavior with infrastructure metrics like GPU, container, and network data.

They will also present a complete reference architecture that uses open-source projects including OpenTelemetry (OTel), Prometheus, Grafana, and some new tools for LLM observability.

Attendees will learn practical ways to build transparent and reliable production AI agent systems.

From Region To Multi-AZ: Building Resilient Cloud Infrastructure With OpenStack, Kubernetes, and OVN - Seungjin Han, kt cloud

Tuesday August 11, 2026 15:55 - 16:25 KST

Orchid 2

As cloud service providers evolve their infrastructure, Multi-AZ architecture becomes essential for service continuity, failure isolation, and operational resilience. However, building a Multi-AZ cloud with open source technologies is not simply about spreading components across data centers. It requires design decisions across compute, networking, storage, observability, automation, and failure validation.

This session shares a CSP’s journey from a region-centric architecture toward a Multi-AZ cloud model using open source technologies such as OpenStack, Kubernetes, OVN, Kube-OVN, OpenStack-Helm, Cluster API, Ceph, and cloud native observability tools.

The talk will cover regional versus AZ-local service design, OpenStack control plane deployment on Kubernetes, zone-aware networking, storage replication, image availability, observability, and DR validation. It will also discuss trade-offs in traffic locality, failover behavior, data consistency, and complexity.

Rather than presenting a vendor-specific platform, this session focuses on reusable architecture patterns and lessons for cloud operators who want to build resilient open cloud infrastructure with open source software.

Maximizing Heterogeneous Memory Bandwidth in Multi-Socket Systems - Rakie Kim, Yunjeong Mun & Honggyu Kim, SK Hynix

Tuesday August 11, 2026 15:55 - 16:25 KST

Orchid 1

The advent of heterogeneous memory like CXL allows systems to secure additional bandwidth, but effectively utilizing it remains challenging. While widely adopted memory tiering optimizes latency by migrating hot pages to fast memory, bandwidth-intensive workloads require utilizing multiple memory tiers simultaneously.

To address this, Weighted Interleaving was introduced to distribute pages proportionally based on each node's bandwidth. However, it has a critical limitation: it ignores the physical topology of multi-socket systems, often leading to inefficient cross-socket memory accesses.

To resolve this, we introduce Socket-aware Weighted Interleave, an advanced memory policy currently being upstreamed to the mainline Linux kernel. It recognizes multi-socket boundaries, preventing performance degradation from unintended remote accesses and maximizing total throughput via localized allocation.

This advanced policy is a newly integrated feature of HMSDK, an open-source toolkit introduced last year. This session will focus primarily on this new capability, exploring how HMSDK efficiently manages large-scale CXL and heterogeneous memory systems.

MCP Adoption and Why OSPO Skills Matter - Ana Jiménez Santamaría, Linux Foundation (TODO Group and PyTorch Foundation)

Tuesday August 11, 2026 15:55 - 16:25 KST

Grand Ballroom 2-3

As organizations explore the Model Context Protocol (MCP), many of the early conversations naturally happen around AI tooling, integrations, and experimentation. At the same time, MCP may also raise questions that are familiar to Open Source Program Offices (OSPOs) and related teams or professionals with open source management experience, including governance, contribution strategy, standards engagement, and cross-functional coordination

This talk reflects on what organizations might gain by bringing those perspectives into MCP discussions earlier, as well as into their broader Agentic AI strategy. Rather than treating MCP only as a technical AI topic, the session will explore it as an area where open source process knowledge may also add value. Attendees will leave with ideas for how OSPOs can contribute to MCP adoption in practical, collaborative, and organization-aware ways

Flexible Paging in Linux: Per-process Page Size - Dev Jain, Arm Ltd

Tuesday August 11, 2026 16:35 - 17:05 KST

Orchid 1

Applications often run faster on a 64K page size kernel than on 4K. This is because larger pages reduce TLB pressure and pagetable walk overhead, greatly improving memory access speed. But, sysadmins are hesitant to use a 16K/64K kernel as most applications have been historically tuned for 4K pages, and larger pages can increase memory waste due to internal fragmentation. This creates a tradeoff between performance and memory waste.

We propose a design that changes the game by separating the page size of the user and the kernel. Instead of enforcing a single system-wide page size, processes can operate under different page-size ABIs. A performance-critical app can use a 64K page-size ABI while still running on a 4K kernel. We achieve this by enabling Linux to provide memory in 64K chunks via 16 contiguous 4K pages, and by translating operations on the 4K page table into a 64K “native” page table that serves as the actual hardware page table.

At the same time, lightweight or memory-sensitive applications can continue using 4K pages to minimize memory waste. All of this happens on the same Linux kernel, without requiring separate builds of the kernel.

From Frankenstein To Kamaji: Lessons in Building a Single CAPI Cluster Across Multiple Providers - Antonia von den Driesch, Giant Swarm

Tuesday August 11, 2026 17:15 - 17:45 KST

Orchid 2

At Giant Swarm we use Cluster API to provision and bootstrap our k8s clusters. With this setup, control plane (CP) and worker nodes must run on the same infrastructure which was never an issue so far...

However, in bare-metal environments, using 128-core servers for CP nodes is luxury. It's far more efficient to host them as virtual machines on a hypervisor while keeping workers on physical hardware. But can we get around CAPI's limitations?

We will walk through how we built Frankenstein's cluster by mixing vSphere for the CP and Proxmox for workers as a testing ground. While technically functional, this required "hacky engineering". We will share the hurdles we hit and the operational risks of this hybrid cluster setup.

Finally, we will demonstrate how we solved this challenge with a cleaner, upstream-friendly alternative. Kamaji lets us run the CP as pods in a management cluster. We achieved even better resource optimisation with full native community support and no custom hacks.

Implementing a Stateless V4L2 Decoder Driver: Architecture and Lessons Learned - SungHo Lee, Chips&Media

Tuesday August 11, 2026 17:15 - 17:45 KST

Orchid 1

Stateless video decoding has become the standard approach in V4L2 using the Request API, but implementing a stateless decoder driver remains complex. It requires careful handling of codec parameters, buffer management, and coordination between userspace and the kernel.

This session presents a practical overview of implementing a stateless V4L2 decoder driver based on real development experience. It covers how SPS/PPS and per-frame parameters are passed from userspace, how reference frames are managed, and how hardware constraints are handled within a generic V4L2 framework.

We also discuss common pitfalls such as synchronization issues and buffer lifecycle management, and highlight key differences from traditional stateful decoders.

Attendees will gain a clear understanding of stateless decoder architecture and practical insights for developing robust V4L2 drivers.

GitAIOps: A 4-Layer Architecture for Predictable AI-Assisted Operations - Hoon Jo, Megazone

Tuesday August 11, 2026 17:15 - 17:45 KST

Magnolia

AI agents have no memory between sessions. Every conversation starts from zero. Git becomes the only persistent memory an AI agent can rely on. GitAIOps is the pattern built on this principle: Git is the memory, and a 4-layer architecture defines what goes into that memory.

I applied this to a production migration: 15 Helm releases, Kafka ZooKeeper-to-KRaft, Redis-to-Valkey, full observability stack rebuild. The question: what does Git need to contain so any AI session picks up where the last one left off?

The answer is a 4-layer Git structure, each layer born from a production failure.
Layer 1: Human plans in Git (36 files, 23,854 lines). Too verbose for AI.
Layer 2: Distilled AI context in Git (6 files, 1,254 lines). 19:1 compression as a project state dashboard.
Layer 3: Command Guardrails in Git (117 files). Enforced ordering, no AI-generated commands.
Layer 4: Locked values in Git (30 files). Zero interpretation, reviewed like code.

Every AI action reads from Git, executes, and commits back. The loop is closed.

DEV: 2 weeks → 2 days. PROD: 1 week → 1 day. The session covers the architecture, each layer's failure, and real production artifacts.

How x402 Brings Open Source Governance to Payments - Junhyeok Yoo, Four Pillars

Tuesday August 11, 2026 17:15 - 17:45 KST

Rose

In April 2026, x402 joined the Linux Foundation with over 20 founding members. It is the first payment protocol under open source governance at the Linux Foundation.

x402 activates HTTP 402 "Payment Required," reserved in 1997 but never used. A server responds with 402 and payment terms, the client settles on-chain, the resource is delivered. Apache 2.0, zero protocol fees, chain-agnostic, no single-organization dependency.

Part 1: Why now. Every internet layer runs on open protocols except payments. That breaks when AI agents must pay at machine speed. We map the agentic payment stack and ask: is it open, who governs it?

Part 2: How x402 works. HTTP 402 challenge-response, stateless architecture, one middleware line to gate any API, production deployments today.

Part 3: Bottom-up to foundation. x402 was open-sourced, developers adopted it, major infrastructure providers shipped native support, competing protocols chose to integrate x402 rather than build a rival. Then it moved to the Linux Foundation.

Part 4: What comes next. The protocol is early. Foundation governance changes the signal. We examine what sustained adoption requires.

Keynote: Zephyr RTOS: 10 Years After Applying OSS Best Practices - Kate Stewart, Vice President of Dependable Embedded Systems, The Linux Foundation

Wednesday August 12, 2026 09:30 - 09:45 KST

Grand Ballroom 2-3

Zephyr initially set out to solve a problem that many embedded teams quietly struggled with: how to build dependable real-time systems without being locked into a single vendor, toolchain, or proprietary stack. The project introduced a new model built around portability, adoption of open source and security best practices, modern tooling, and a shared ecosystem of drivers and middleware.

From the start, there was the commitment to apply known best practices to its development. While Zephyr is a different code base, a lot of the lessons learned from developing the Linux Kernel were applied. The project has also focused on incorporating security best practices from the start which now enables it to make compliance easier for manufacturers looking to conform to the emerging Cybersecurity Resilence Act (CRA).

Best practices have also enabled the project to work towards achieving formal safety certification for 61508 and 26262. The project has achieved 61508 concept approval at this point, as is working towards formal certification, using a combination of traditional V-Model analysis, and innovative techniques to keep up with the speed of open source development.

Building and Orchestrating Production-ready Agentic AI Systems - Kevin Dubois, IBM & Daniel Oh, Red Hat

Wednesday August 12, 2026 11:00 - 11:30 KST

Orchid 2

Agentic AI is all the hype right now, but how do you actually implement such a system for real enterprise, cloud based use cases?

The challenge for developers, architects and platform engineers alike lies in custom building agents, and even more so, orchestrating these agents to collaborate effectively towards a common goal. Unfortunately though, despite all the promises from vendors, a "one-size-fits-all" or “off-the-shelf” approach just doesn't work due to the complex nature of software. In addition, just like traditional apps, these agentic systems will likely need to be deployed, managed and observed in cloud environments.

In this session we'll explore:
* The spectrum of Agentic AI patterns
* A real world-ish implementation of a highly performant - open source - agentic system (with Java!)
* Deploying this agentic system to Kubernetes
* Other considerations such as observability and fault tolerance to get it all running smoothly in production.

Exploring Unikernel: An Empirical Comparison With Linux - Taekyung Kang & Kyungha Kim, Boeing

Wednesday August 12, 2026 11:00 - 11:30 KST

Magnolia

Unikernels are specialized operating systems designed for efficiency by including only the components needed by an application. By eliminating the traditional user–kernel separation and omitting general-purpose services such as background daemons and unused device drivers, this design reduces system complexity and overhead while providing a fundamentally different execution model from conventional Linux systems.
This study examines the structure of Unikraft-based unikernels from a library operating system perspective. It also presents an empirical comparison with Linux under controlled conditions. Both systems were deployed on the same Xen hypervisor and executed on a hardware platform, running the same application with a common subset of POSIX APIs. Execution latency was measured, and assembly-level analysis was performed to investigate potential reasons for the observed differences.
The results are presented as an example of combining performance measurement and low-level inspection when analyzing specialized operating systems. Similar approaches may be applicable to other specialized OS or unikernel contexts, depending on the application and execution environment.

From CVEs To Compliance: Automating Embedded Linux Kernel Security - Kyungsik Lee, LG Electronics

Wednesday August 12, 2026 11:40 - 12:10 KST

Magnolia

Global security regulations such as the EU Cyber Resilience Act (CRA) have raised security requirements for embedded products. Open source components, especially the Linux kernel, must now support systematic vulnerability management, fast security patching, and long-term maintenance, making kernel security a key challenge.

This session discusses practical solutions for managing Linux kernel vulnerabilities in embedded products. It begins with an overview of recent kernel CVE trends and their impact on long-lived and customized kernels. The session then introduces a CI-based vulnerability response pipeline designed to minimize the time from CVE disclosure to patch deployment.

A key challenge is backporting security fixes to older or vendor-modified kernels, where patches often do not apply cleanly. To address this, the session presents an AI agent–based approach that assists developers by analyzing CVE data, upstream patches, and kernel context to suggest candidate backports.

By adopting an AI-assisted vulnerability response workflow, teams can reduce response time and prepare for compliance with evolving global security regulations.

Simplifying AI for Edge Compute with HAMi - Reza Jelveh, Dynamia

Wednesday August 12, 2026 11:40 - 12:10 KST

Rose

Open-source agents like Hermes and OpenClaw can reason and use tools, but edge deployment is still hard - not the model, the compute underneath: limited memory, tight power budgets, no ops team. Democratizing agentic AI means fixing the compute layer. This deep dive covers GPU and memory slicing at the edge: carving one device’s unified memory so multiple agents run concurrently on hardware as small as an NVIDIA Jetson, and time-sharing when demand exceeds memory.

We compare Jetson-class GPUs with NPUs from Axelera and DeepX - higher performance per watt - and what it takes to make them schedulable. HAMi, the CNCF Incubation project for hardware-agnostic GPU virtualization, is that layer: one scheduling plane across heterogeneous accelerators, fine-grained memory slicing, open source. A blueprint for edge AI without a cloud budget.

From Closed To Collaborative: Perspectives and Lessons From Qualcomm’s Open Development Experience - Craig Northway, Qualcomm Technologies Inc

Wednesday August 12, 2026 13:35 - 14:05 KST

Magnolia

For more than 15 years, Qualcomm’s been actively involved in a range of Open Source ecosystems. Until recently, some parts of our development were handled behind closed doors, with contributions coming a bit later and enablement being somewhat limited. We tried various projects and partnerships to push things upstream sooner, but it wasn’t until lately that we truly made a complete shift.

Over the past 18 months, we’ve totally revisited our approach—moving an entire Linux product development ecosystem, with hundreds of contributors, from a private downstream setup to a full-blown Open Development model. This wasn’t just a surface change: it meant overhauling how our engineers work, syncing up our internal systems with open practices, and fundamentally changing the way our developers connect and collaborate.

In this session, we’ll share what made this transition work for us—including how we managed to weave our internal systems into Open Source workflows, encouraged developers to embrace new ways of thinking, and built scalable processes that can handle all sorts of Linux ecosystems and distributions.

Trusted OSS is an open-source self-certification kit that guides any organization from zero to ISO/IEC 5230 (license compliance) and ISO/IEC 18974 (security assurance) conformance using AI agents.
No prior expertise required.

Built by the OpenChain Korea Work Group and released under CC BY 4.0, the kit features:

• AI agents (Claude Code) that auto-generate company-specific compliance artifacts: OSS policy, SBOM, vulnerability response procedures, training curriculum, and conformance declaration
• DevSecOps pipelines (SAST, SCA, secret detection, IaC) ready to drop into any CI/CD environment
• A 5-level AI Coding Governance Maturity Model — from ad-hoc prompting (Level 1) to AI-augmented defense (findings-driven review, AI fuzzing) and continuous auto-remediation (Level 5).

In this session, I'll walk through how any team can go from no compliance process to a fully documented, self-certifiable program in hours, not months. I'll also share how we're using AI to close the compliance skills gap across Korean enterprises and SMEs — making OpenChain certification accessible to all.

Clouds on Clouds: OpenStack and Kubernetes With Cloud-Barista - Seokho Son, ETRI

Wednesday August 12, 2026 14:15 - 14:45 KST

Orchid 2

Can you build OpenStack and Kubernetes clusters anywhere, across multiple clouds, and still understand how network connectivity works?

This session explores that question through a scenario using Cloud-Barista, an open-source multi-cloud orchestrator.

Instead of separate project overviews, this talk connects Cloud-Barista, OpenStack, and Kubernetes as infrastructure layers. Cloud-Barista provisions VMs on public clouds, then OpenStack is deployed on them. The OpenStack-based cloud is registered back into Cloud-Barista to create VMs and host a web service.

Will that service be reachable from Internet? If not, why? What makes it complex? These questions guide our explanation of network paths and reachability. We will apply the same lens to Kubernetes on multi-cloud VMs.

The focus is not just automation, but how connectivity works: public/private IPs, bastion access, cluster nodes, and how users reach workloads.

Beginners curious about these topics will gain practical insight into open-source infrastructure stacks.

This is not another cluster deployment talk. It is an experimental journey across open-source cloud layers, from multi-cloud IaaS to OpenStack and Kubernetes.

AI coding tools can generate patches quickly, but maintainers still cannot merge a PR on generated code alone. They need evidence, what was reproduced, what changed, how it was validated, and whether the contributor actually reduced review work instead of shifting it downstream.

In this session, I draw on recurring patterns from reviewing and maintaining Argo CD contributions to show why many AI-assisted PRs stall and what makes others move quickly. I present a simple four-stage framework for review-ready OSS contributions, Set up the environment, validate the problem before changing code, harden the fix with tests and checks, and submit a PR with enough context and proof for efficient review.

From Continuous Tracing To Automated Insights: AI-Driven Performance Analysis With Guider - Peace Lee & Jaeguk Lee, Hyundai Motor Company

Wednesday August 12, 2026 14:55 - 15:25 KST

Orchid 1

Catching transient performance drops is notoriously hard; by the time you attach a profiler, the bottleneck is often gone. Continuous tracing is the solution, but manually analyzing the resulting massive data is a huge hurdle.

This session introduces a practical methodology for always-on performance monitoring and automated analysis using Guider. First, we demonstrate how Guider efficiently profiles system performance in the background with minimal overhead. Upon detecting an anomaly, it automatically generates a retroactive report using trace data captured just before the event.

We will then show how to feed these structured reports into an AI pipeline. Instead of manually deciphering complex kernel metrics, you will see how AI instantly pinpoints the root cause of performance regressions.

Attendees will learn to build a continuous monitoring pipeline that automatically turns raw trace data into real-time, actionable insights.

Live Demo: Event-Driven Terraform Drift Detection With Falco - Keita Higaki, Sysdig,Inc

Wednesday August 12, 2026 16:35 - 17:05 KST

Orchid 2

Terraform is widely used to manage infrastructure as code, but traditional drift detection relies on periodic scans or manual checks such as terraform plan. This approach often fails to detect real-time changes, manual modifications, or unauthorized actions.

In this technical feature demonstration, we present an open source approach to drift detection using an event-driven model powered by Falco.

We will demonstrate how:

infrastructure is provisioned using Terraform
manual or out-of-band changes introduce drift
Falco detects these changes in real time via event streams
an open source tool analyzes and surfaces these events as actionable drift signals

Unlike traditional drift detection tools, this approach enables near real-time detection, user attribution, and continuous visibility into infrastructure changes.

This session introduces the concept of “event-driven runtime drift” and shows how it complements Terraform-based workflows using open source technologies.

The demo is based on a publicly available open source project, allowing attendees to reproduce the setup and apply it to their own environments.

Reboot Without Rebooting: Updating Linux Userspace at the Speed of a Service Restart - Nandakumar Raghavan & Prasanna Kumar T S M, Microsoft

Wednesday August 12, 2026 16:35 - 17:05 KST

Orchid 1

What if you could replace your entire OS userspace — binaries, configs, services, even init itself — without ever stopping the kernel? No firmware POST, no hardware re-init, no multi-minute downtime. Just a clean userspace restart in seconds.

That's what soft-reboot (systemctl soft-reboot), implemented in systemd, delivers: a primitive that tears down all of userspace, pivots into a fresh root filesystem, and re-launches PID 1 — while the running kernel stays untouched.

This talk unpacks how soft-reboot works under the hood, why it matters for modern OS update workflows, and how it compares to a traditional reboot and kexec. We'll walk through real production use cases: zero-downtime OS updates, staged fleet rollouts, and rapid recovery from a wedged userspace — without paying the cost of a full boot cycle.

Attendees will leave with a clear mental model of soft-reboot internals, practical guidance on when to choose it over a full reboot or kexec, and concrete patterns for building soft-reboot-aware update pipelines.

If you've ever wished you could ship an OS update as fast as restarting a service, this talk is for you.
