Firecracker contained the agent in testing, but the agent still hardlocked the host through Linux kernel flaws. ### Source excerpt Traditional virtual machines are inadequate for isolating cyber-capable autonomous agents. Tests using GPT-5.6-Cyber indicated multiple escape attempts due to kernel flaws. While Firecracker provided some containment, vulnerabilities remained. The study underscores the need for minimal attack surface virtualisation technologies and rapid, proactive patching strategies to safeguard host systems.

But that operation of writing a minimal yet working Unix kernel for the 386 (at the beginning Linux was, let's say, mono-architecture) was something within the reach of many other programmers and students. Many in the sense of, I don't know, 0.1%, one in a thousand, one in ten thousand. Obviously most people are not able to do this kind of feat, but a lot of people are. If you look at Hacker News in the latest years, you'll see how many projects of kernels written in C, microkernels implemented from scratch, kernels written in Rust, kernels made in all sauces and manners, small Unix systems created vertically for the Raspberry Pi, operating systems for the ESP32 and so forth. Writing a kernel is not something within everybody's reach, but it is something that many can complete, if they put enough effort into it. Then, of course, not everybody will do it well. He is a genius programmer, without any doubt, so he did it better. And yet, of Linus there is only one. This implementative capacity of his, in fact, would not tell us much about him: what we should focus on, instead, is what happened later. ## He stopped writing code Among the maintainers of the famous open source projects, he was one of the very few that, very early in the history of the development of Linux, almost completely stopped writing code in order to concentrate on the leading of the project. On being the leader, the coordinator, the single mind holding the clarity about what the goals of the project must be, and so on. And this is a rare thing. Many maintainers (myself included, for a long time) continue instead to implement things directly, to not delegate much, an ## Безопасность микроядра: где заканчивается трюизм и начинается инженерия DevFeed: [Безопасность микроядра: где заканчивается трюизм и начинается инженерия]() Original publisher: [Read original article]() Author: AnnaTref ("Лаборатория Касперского") Published: 2026-07-16T12:16:48Z Content type: article Language: ru Sources: ["Лаборатория Касперского" RU]() Topics: [Kernel](), [Linux]() Tags: [kasperskyos](), [kernel](), [linux-kernel](), [os](), [tag-4d5248fd6bfe](), [tag-6a561fc81855](), [tag-9fe8963de219](), [tag-a7f27c878c10](), [tag-cf876daf714c]() ### AI overview This article examines the security architecture of microkernel-based operating systems, using KasperskyOS as context. It discusses why a smaller trusted code base and attack surface may enable different hardening strategies, how data transfers from user space can be secured, and how microkernel protections compare with those in monolithic kernels. ### Source excerpt Привет, Хабр! Меня зовут Анна Мелехова, я старший архитектор ПО в "Лаборатории Касперского". Вместе с командой занимаюсь разработкой микроядерной KasperskyOS. Безопасность микроядра часто воспринимается как почти очевидный тезис, то есть трюизм: микроядро компактное, драйверы вынесены в user space, а значит, поверхность атаки меньше и система в целом безопаснее. Но за этим базовым утверждением скрывается множество менее очевидных инженерных решений -- случаев, когда количественное сокращение приводит к качественно иной архитектуре безопасности. В этой статье, основанной на моем докладе для OS DevConf 2025, разберем, почему механизмы харденинга могут эффективнее работать в микроядре, чем в монолите; как "закрутить гайки" при передаче данных из user space; и насколько отличаются защитные механизмы в микроядерной архитектуре и в монолитной.

It explains how documenting the previously undocumented SO_TIMESTAMPNS feature led to his first man-pages patch and eventually to a career focused on clarity in open source communities. Google sponsors his work on the Linux Kernel man-pages project. ### Source excerpt by Daryl Ducharme, Google Open Source When you think of "innovation" in open source, your mind probably jumps to the latest AI model or a revolutionary new framework. You might not immediately think of manual pages. Even Alejandro "Alex" Colomar, who spends his days maintaining Linux Kernel documentation, jokingly admits that some might find the work "boring" because it focuses on fixing existing issues and documenting new features rather than flashy inventions. But as any developer knows, the most powerful code is only as good as the documentation behind it. At Google, we believe that investing in the success of projects we don't own is a core part of being a good open source citizen. That is why we are proud to sponsor Alejandro's work on the Linux Kernel man-pages project--supporting the critical infrastructure that many of our own systems rely on every day. Documentation is the gift you give to your future self and your whole community. The precision of a robot Alejandro's journey into the world of essential documentation started at university. He was working with robotic arms that used a proprietary scripting language. Wanting more control, he decided to write a C library to communicate with the robots over the network by sniffing packets with Wireshark. It worked, but it was slow--he had to wait seconds between commands to ensure the robot had finished moving. To make the movements smooth, he needed to understand the messages the robot was sending back in real-time. This required high-precision timing. He found SO_TIMESTAMP, which provided microsecond precision, but he noticed a macro called SO_TIMESTAMPNS in the header files that promised nanosecond resolution. The problem? It wasn't documented in the manual page. The first patch After figuring out how to use the undocumented feature by looking at the kernel source code, Alejandro decided to ensure the next person wouldn't have to struggle. He cloned the man-pages repository, wrote a new paragraph based on exis ## 【eBPF 内核实现深度拆解】从验证器到 JIT，从 BTF 到调度器 DevFeed: [【eBPF 内核实现深度拆解】从验证器到 JIT，从 BTF 到调度器]() Original publisher: [Read original article]() Author: Liao Tonglang Published: 2026-06-12T00:00:00Z Content type: article Language: zh Sources: [土法炼钢 - 系统与基础设施]() Topics: [eBPF](), [Linux](), [JIT](), [Benchmark](), [clang](), [hash](), [benchmarking](), [RISC-V](), [ast-matchers]() Tags: [arm](), [array](), [benchmark](), [bpf-jit](), [bpf-maps](), [bpf-verifier](), [btf](), [clang](), [co-re](), [cpu](), [ebpf](), [fentry](), [hash](), [jit](), [kernel](), [libbpf](), [linux](), [linux-kernel](), [precision](), [risc-v](), [sched-ext](), [trampoline](), [x86](), [xdp]() ### AI overview This Chinese-language series systematically explains eBPF's Linux kernel implementation, covering the BPF instruction set and registers, verifier algorithms, JIT compilation, map data structures and concurrency, helper type checking, BTF and CO-RE relocation, libbpf loading, trampolines, and sched_ext interfaces.

It also observes that forwarded traffic uses ECMP while locally originated traffic does not, despite different routing-table entries. ### Source excerpt When I wrote about the anycast-ECMP-in-MPLS behavior in 2011, I had to use Cisco IOS to prove that ECMP worked, since Arista cEOS (running the Linux kernel for IP forwarding) didn't install more than one equal-cost path into the Linux forwarding table. Arista cEOS got better in the meantime; IPv4 ECMP works like a charm on cEOS release 4.35.02F.
