A safety net for eBPF: adding KASAN support to JITed programs

The eBPF technology implemented in the Linux kernel keeps on gaining traction in various areas: infrastructure, observability, security, debugging, and many more. Its wider adoption reinforces one core concept that drives its development: it must be safe for the kernel to load an eBPF program, and so a program that cannot be proven to be safe must be rejected. This fundamental concept led to the development of some complex mechanisms such as the BPF verifier; but this guarantee is not foolproof: the verifier is written in C and can have the same kinds of bugs as the rest of the kernel. Addressing this kind of risk is a key strategy for Alpha-Omega, which is funding initiatives to improve the security and safety of widely used software projects and technologies. Alpha-Omega allocated a grant to the eBPF Foundation, which teamed up with Bootlin, to improve the security and safety of the eBPF technology by implementing KASAN support in eBPF programs, with the goal of enabling better detection of memory-safety issues for eBPF subsystem developers.

Bootlin engineer Alexis Lothoré invited at the Linux Storage Filesystem & Memory Management & BPF Summit

LSF, MM & BPF Summit The Linux Storage, Filesystem, Memory Management & BPF Summit (LSFMMBPF) brings together leading developers, researchers, and Linux kernel subsystem maintainers to discuss, design, and implement improvements to the filesystem, storage, and memory management subsystems. The work initiated at this event typically makes its way into the mainline kernel and Linux distributions within the following 24 to 48 months.

In the context of the partnership between Bootlin, the eBPF Foundation and the Alpha Omega organization, Bootlin engineer Alexis Lothoré is currently working on adding KASAN memory checker support to the eBPF subsystem: this work aims to make it easier for eBPF subsystem developers to catch (early) bugs that could be introduced in complex parts of the kernel, like in the eBPF verifier.

This work has already led to some initial design discussions and proof of concept implementation on the kernel mailing lists, but as it requires some close collaboration with kernel developers and maintainers, Alexis has also been invited to attend LSFMMBPF 2026, taking place from May 4th to May 6th in Zagreb, Croatia, and will present his ongoing work on “Adding KASAN support for JITed programs”. This will be the opportunity to discuss and iron out the roadblocks and details to get the feature integrated in the kernel, as this event is not really a classic conference in which people primarily attend talks: the goal really is to trigger discussions to make solutions and features move forward in the kernel, in a “workshop-like” atmosphere. This work is one among many others on-going topics in the Linux kernel that need discussions, more details are available in the full event schedule.

We are proud to have one of our engineers contributing to this gathering of Linux kernel experts. This invitation highlights Bootlin’s strong involvement in upstream Linux kernel development.

Bootlin engineer Luca Ceresoli speaks at Linux Day 2025 in Bergamo, Italy

Linux DayBootlin is happy to share that our engineer Luca Ceresoli will be speaking at Linux Day 2025 in Bergamo, Italy, on Saturday, October 25, 2025.

Luca’s talk, titled “Software updates on embedded Linux devices” (“Aggiornamenti software su dispositivi embedded Linux”), will take place from 14:00 to 15:00.

About the talk

Many of the electronic products we use every day are powered by Linux, even when we don’t see it. Like PCs, these embedded devices also need software updates to fix bugs and improve functionality. However, unlike PCs, they must perform these updates automatically and reliably, without any user intervention.

In his presentation, Luca will explain one of the most widely used techniques for achieving this: A/B updates. He will describe what they are, how they work, and the most common tools used to implement them in embedded Linux systems.

This talk is a great opportunity for developers and engineers interested in the practical challenges of maintaining and updating Linux-based devices in the field.

About Linux Day

Linux Day is an annual, nationwide event organized across Italy to promote the use and understanding of free and open-source software. Many cities host talks, workshops, and meetups aimed at both newcomers and experienced developers. The Bergamo edition continues this tradition with a full day of technical sessions, community engagement and an install party.

Meet Luca and Bootlin

If you’re attending Linux Day Bergamo 2025, don’t miss Luca’s session! Don’t hesitate to meet Luca to talk about what we do at Bootlin and open job positions!
