Rethinking Writeback: Scaling Linux Filesystem and Memory Performance for the Next Decade - Kundan Kumar, Samsung R&D Institute India - Bangalore & Anuj Gupta, Samsung Semiconductor India

Monday August 25, 2025 11:20 - 12:00 CEST

Linux’s current writeback infrastructure, while robust, was designed before large folios, CXL-tiered memory, and AI workloads demanding low-latency, high-throughput I/O. Today, workloads like RAG pipelines using vector databases with buffered I/O, and memory tiering on CXL, are exposing scalability limits in how the kernel handles writeback.

This talk presents a forward-looking view on evolving Linux’s writeback model. We’ll explore how the single-threaded design stalls page migration and reduces memory compaction effectiveness—affecting hugepage allocations and folio movement across memory tiers, contributing to fragmentation. On the storage side, parallelizing writeback improves throughput and responsiveness under dirty-page pressure, especially for sustained-write workloads with large memory footprints on High capacity SSDs.

We’ll also touch on early experiments within the kernel community, including efforts to make writeback more filesystem-geometry aware and parallelize it based on overwrites/new allocations.

This session invites open source community to reimagine writeback as a scalable, performance-critical component in Linux.

Upstream Kernel Hardening: Progress on Enabling -Wflex-array-member-not-at-end - Gustavo A. R. Silva, The Linux Foundation

Monday August 25, 2025 13:30 - 14:10 CEST

The -Wflex-array-member-not-at-end compiler option was introduced in GCC 14. At the time, it revealed around 60,000 warnings in the upstream Linux kernel. While many of these were duplicates, about 650 are unique and require individual auditing and attention. These issues span different categories and vary in complexity, which adds to the challenge of globally enabling this compiler option in the upstream Linux kernel.

In this presentation, we'll share the progress we've made on this work as part of the Kernel Self-Protection Project (KSPP) over the past few months. We'll go over the challenges we've encountered, show concrete code examples, and demonstrate how to fix these kinds of problems. We'll also discuss why enabling this option is important for the kernel, and how we plan to complete this work in the near future.

Whether you're a seasoned kernel developer or someone looking to start contributing upstream, this presentation will introduce useful helpers and strategies you can use to fix existing code or implement new functionality, and in doing so, help us harden the upstream Linux kernel for the benefit of everyone.

Extending BCC as a Data Source for System Monitoring - Eunseon Lee, LG Electronics

Monday August 25, 2025 14:25 - 15:05 CEST

eBPF enables efficient tracing and monitoring of modern Linux systems. However, tools in the BCC (BPF Compiler Collection) are primarily designed for standalone use, making it challenging to adopt them directly in real-time, streaming-based observability systems.

This talk introduces a practical approach to extending BCC tools for use as data sources in system monitoring pipelines. I demonstrate an architecture that transforms BCC output into time-series data by integrating with InfluxDB, and visualizes the data using Grafana. This enables real-time tracking of kernel and user-space events such as memory allocation over time.

I also explore enhancements to existing BCC tools, such as adding options to output data in time-series–friendly formats (e.g., InfluxDB’s line protocol), enabling easier ingestion by monitoring agents. These modifications help bridge the gap between raw eBPF observability and modern telemetry systems, without compromising BCC’s standalone usability. GitHub PR (https://github.com/iovisor/bcc/pull/5281) demonstrate these improvements.

Attendees will learn to leverage BCC tools for real-time insights and contribute enhancements for broader monitoring use cases.

The Power of the Device Mapper - From Dm-cache To Dm-zoned - Werner Fischer, Thomas-Krenn.AG

Tuesday August 26, 2025 11:55 - 12:35 CEST

The device mapper has been part of the Linux kernel since kernel version 2.6. It allows the creation of virtual block devices by mapping their address space to other block devices or special functions. In this way, it can map physical block devices such as hard disks or SSDs to higher-level virtual block devices. It is the basis for the Logical Volume Manager (LVM), Linux software RAIDs and dm-crypt encryption, and provides additional features such as file system snapshots.

However, the use of Device Mapper targets is not limited to that. Many other targets offer often unknown features. Most of these are intended for production use. However, there are also some targets designed specifically for debugging.

In this talk, Werner gives a full overview of all Device Mapper targets.

For production use these are: dm-cachd, dm-clone, dm-crypt, dm-ebs, dm-era, dm-integrity, dm-linear, dm-mirror, dm-raid, dm-stripe, dm-switch, dm-thin, dm-unstripe, dm-verity, dm-vdo, dm-writecache and dm-zoned.

For debugging: dm-delay, dm-dust, dm-flakey and dm-zero.

He also briefly shows drbd, md (RAID) and bcache, which, like device mapper targets, can work as devices "on top" of normal block devices.

Understanding Data Races in the Linux Kernel - Abhirup Vijay Gunakar, Arizona State University

Tuesday August 26, 2025 11:55 - 12:35 CEST

Data races in the Linux kernel can lead to unpredictable behavior, silent data corruption, and severe security vulnerabilities. In this session, we’ll explore how concurrency works in the kernel, explain the root causes of kernel data races, and illustrate how they can silently destabilize entire systems.

We’ll then dive into the Kernel Concurrency Sanitizer (KCSAN), a specialized tool that helps developers detect data races in kernel code. You’ll learn how KCSAN differs from user-space tools like ThreadSanitizer (TSan), understand its dynamic instrumentation approach, and see how to read typical race reports. We’ll also discuss best practices for preventing kernel data races: consistent use of spinlocks, mutexes, atomics, and lock ordering conventions.

By the end of this talk, you’ll grasp the core challenges of concurrency in the Linux kernel, know how to spot and diagnose data races using KCSAN, and walk away with proven techniques for keeping kernel code race-free and reliable.

Extending Container Performance Isolation: Regulating Memory Bandwidth & Cache in the Kernel - Jonathan Perry, Unvariance

Tuesday August 26, 2025 14:10 - 14:50 CEST

While containers provide isolation for CPU cycles and memory capacity, they offer limited protection against performance interference through shared CPU caches and memory bandwidth. Such contention was shown to increase application response times by 4-13x. The Linux resctrl infrastructure provides monitoring and control mechanisms, but has limitations for controlling real-world applications.

For example, child processes do not inherit their parent's resctrl groups, leaving any application that forks improperly monitored and controlled. Additionally, the current filesystem-based interface makes it difficult to build a controller that can monitor and adjust quickly enough to keep up with frequently changing application memory behavior.

This talk introduces the memory interference problem and presents new kernel mechanisms to address these limitations. A new collector enables effective control by capturing per-container measurements of cache and memory bandwidth usage at millisecond frequencies. We'll cover how the solution combines Intel RDT, AMD QoS, high-resolution timers, perf counters, and cgroups to achieve this. We'll discuss future work and opportunities for collaboration.

Hybrid THP Mechanism. Selective Use of Huge Pages by Hot Applications - Asier Gutierrez, Huawei

Tuesday August 26, 2025 14:10 - 14:50 CEST

Currently, THP policies are used globally, for the entire system. This leads to memory fragmentation and memory waste. Main memory has increased a lot faster than TLB entries, and it will continue to do so. Given the limited TLB cache entries, this becomes a serious bottleneck for real world applications. Huge pages are supposed to resolve this issue, since the a single entry in the TLB can map a big chunk of memory. However, this eventually leads to memory fragmentation and eventually the system runs out of usable memory. Hence, most sysadmins and user space application suggest to disable huge pages

We introduce a hybrid page mechanism where hot applications can use huge pages transparently, while avoiding the entire system to use huge pages.

During the talk, we will show how we managed to decrease the huge page consumption as well as benchmarks on real applications.

More Effective Approach To Detecting Potential Deadlocks, DEPT(DEPendency Tracker) - Byungchul Park, SK hynix

Tuesday August 26, 2025 15:05 - 15:45 CEST

Lockdep is a tool in the Linux kernel designed to detect potential deadlocks by tracking the order in which locks are acquired. However, deadlocks can occur not only due to incorrect lock acquisition order, but also from waits that cannot be resolved. For more effective deadlock detection, it is crucial to track the waits and events themselves, rather than focusing on lock acquisition order. This is where DEPT (DEPendency Tracker) comes in. DEPT accurately identifies conditions that can lead to deadlocks by tracking waits and events. Let me introduce DEPT and explain how it works.

Data Placement in Linux: Evolving Block and File I/O - Kanchan Joshi, Samsung Semiconductor

Tuesday August 26, 2025 16:20 - 17:00 CEST

As technologies evolve, so must Linux. Flexible Data Placement (FDP) is a new storage capability that gives the host more influence over the physical data layout—crucial for improving performance, usable space, and overall energy efficiency.

While initial Linux support was possible through an io_uring-driven passthrough interface, many real-world deployments require block and file path support, as well as collaboration across the I/O stack.

This talk will present the current state in Linux, dive into key design decisions, and walk through how both block and file I/O paths are being adapted to better take advantage of data placement. Expect discussion around the use of per-file and extended per-I/O interfaces that involve io_uring, filesystems, the block layer, and the NVMe driver.

Whether you are developing filesystems, optimizing performance tools, or are simply curious about how Linux keeps up with evolving hardware, this presentation offers a glimpse into the next stage of I/O evolution with deeper software–hardware coordination.

Strategies for Rate Limiting Network Packet Ingress - Schuyler Patton & Daolin Qiu, Texas Instruments

Wednesday August 27, 2025 15:05 - 15:45 CEST

A major concern of a network connected application on an embedded platform is reducing any impact from high network traffic that is unrelated to the running application. Typically, this is called network broadcast storms and network attacks. Rate limiting packet ingress is a key strategy in preventing high processor bandwidth consumption caused by a network storm. In general, rate limiting packet ingress implies intentionally dropping packets. In order to setup ingress rate limiting, several different options are possible. These options include evaluating the tc Linux utility (e.g. tc qdisc), eBPF, or simply adjusting the Ethernet PHY link speed. A demonstration of these three options in action and how they can be used to prevent high-rate ingress traffic from causing negative processor impact will be showcased. A comparison of the impact from using tc and eBPF will also be discussed. The overall goal is to use these options to drop ingress packets in order to minimize ARM microprocessor bandwidth.
