Linux namespaces are a resource isolation technique. Each namespace type wraps some global system resource in an abstraction that makes it appear to the processes within the namespace that they have their own isolated instance of that resource, when in fact there are multiple instances of the resource, with each instance private to a particular group of process. Namespaces are key building blocks for a number of interesting technologiesmost notably containers, but also a range of other interesting applications such as Flatpak and Firejail. In this presentation we'll look at various Linux namespace typesincluding UTS, mount, network, and PID namespacesin order to understand what resources they govern and what use cases they serve. Along the way, we should have time for a live demo or two, so as to make the "theory" more concrete.

Network Namespaces Basics Explained in 15 Minutes

Get introduced to the basics of Network Namespaces in Linux. Access full course here: 🤍 Network Namespaces are used by containerization technologies like Docker to isolate network between containers. We’ll start with a simple host. As we know already containers are separated from the underlying host using namespaces. So what are namespaces? When the container is created we create a network namespace for it that way it has no visibility to any network-related information on the host. Within its namespace the container can have its own virtual interfaces, routing and ARP tables. The container has an interface. To create a new network namespace on a Linux host, run the ip nets add command. In this case we create two network namespaces read and blue. To list the network namespaces run the ip netns command. To list the interfaces on my host, I run the ip link command. I see that my host has the loopback interface and the eth0 interface. Now, how do we view the same within the network namespace we created? How do we run the same command within the red or blue namespace? Pre-fix the command with the command ip netns exec followed by the namespace name which is red. Now the ip link command will be executed inside the red namespace. Another way to do it is to add the –n option to the original ip link command. Both of these are the same, the second one is simpler though. But remember this only works if you intend to run the ip command inside the namespace. As you can see it only lists the loopback interface. You cannot see the eth0 interface on the host. So with namespaces we have successfully prevented the container from seeing the hosts interface. #NetworkNamespacesBasics #KodeKloud

Samuel Karp Amazon Web Services In this session, we’ll explore the different Linux primitives that are commonly used in implementing container runtimes. We’ll learn about the Linux primitives that underlie container runtimes like Docker, including cgroups, namespaces, and union filesystems. We’ll see how Docker uses these primitives, and how the OCI standard makes it possible to customize how your containers run. We’ll also discuss alternative container runtimes like CRI-O, rkt, and systemd-nspawn and what makes them different. This will be an interactive session with a live demo and open questions.

with Jérôme Petazzoni, Tinkerer Extraordinaire, Docker Linux containers are different from Solaris Zones or BSD Jails: they use discrete kernel features like cgroups, namespaces, SELinux, and more. We will describe those mechanisms in depth, as well as demo how to put them together to produce a container. We will also highlight how different container runtimes compare to each other. Learn more about Docker 🤍 Docker is an open platform for developers and system administrators to build, ship and run distributed applications. With Docker, IT organizations shrink application delivery from months to minutes, frictionlessly move workloads between data centers and the cloud and can achieve up to 20X greater efficiency in their use of computing resources. Inspired by an active community and by transparent, open source innovation, Docker containers have been downloaded more than 700 million times and Docker is used by millions of developers across thousands of the world’s most innovative organizations, including eBay, Baidu, the BBC, Goldman Sachs, Groupon, ING, Yelp, and Spotify. Docker’s rapid adoption has catalyzed an active ecosystem, resulting in more than 180,000 “Dockerized” applications, over 40 Docker-related startups and integration partnerships with AWS, Cloud Foundry, Google, IBM, Microsoft, OpenStack, Rackspace, Red Hat and VMware.

Current State of Kernel Audit and Linux Namespaces, Looking Ahead to Containers

Current State of Kernel Audit and Linux Namespaces, Looking Ahead to Containers - Richard Guy Briggs, Red Hat Namespaces have been around since the mount namespace was introduced over a decade ago and audit was introduced a couple of years later. Since then, audit's relationship with namespaces has evolved to restrict everything to PID and user initial namespaces for reporting integrity reasons, but then start to loosen things up again, first listening in all network namespaces, then permitting user audit message writes from any PID namespace. Looking forward, audit will need to run in containers, possibly for distributions, but more likely for docker micro-services to meet new certification requirements. Anchoring the audit daemon in the user namespace with its own rulespace and queue looks to make the most sense. Since the kernel has no concept of containers, identifying namespaces in audit messages will equip tracking tools to follow process events in containers. About Richard Guy Briggs Richard was an early adopter of Linux, having used it since 1992. He was also a founding board member of Ottawa Canada Linux Users Group and a speaker at the inaugural Ottawa Linux Symposium. Richard has written UNIX and Linux device drivers for telecom, video and network applications and embedded devices, having a good knowledge of IPsec protocols. He is comfortable in C, bash, Perl, with a soldering iron, oscilloscope, at a podium or chalkboard. He is now a Red Hat kernel security engineer.

User namespaces are at the heart of many interesting technologies that allow isolation and sandboxing of applications, for example running containers without root privileges and sandboxes for web browser plug-ins. In this presentation, we'll look in detail at user namespaces, building up a basic understanding of what a user namespace is and going on to questions such as: what does being “superuser inside a user namespace” allow you do (and what does it not allow); what is the relationship between user namespaces and other namespace types (PID, UTS, network, etc.); and what are the security implications of user namespaces? We'll also explore some simple shell commands that can be used for creating and experimenting with user namespaces in order to better understand how they work. Along the way, there will hopefully be time for a few live demos. You will likely find it helpful to attend my other presentation, "Linux namespaces", beforehand, but this is not essential.

The Linux Foundation Embedded Linux Conference 2013 Namespaces for Security By Jake Edge San Francisco, California Namespace support has been growing in the Linux kernel, so there are now a number of ways that namespaces can be used to help protect Linux systems (embedded or otherwise) from exploits. Using namespaces (in particular, the mount, network, and user namespaces) can isolate processes in ways that will prevent some types of vulnerabilities from compromising more of the system. Namespaces can be used as part of a "defense in depth" strategy to avoid the harm (or most of the harm) from exploits of vulnerable user-space applications. This talk will be for developers of embedded systems, particularly "system level" developers. It will assume some knowledge of C and Linux, but not require in-depth knowledge of either. Participants can expect to come away with a good foundation on what namespaces are and can do, along with concrete ideas of how to use namespaces in their projects.

20.04.2020

User namespaces have become one of the most important security features for container workloads. But since they can be created by any user on the system they restrict access to a wide range of features including mounting of filesystems. In recent years a lot of work went into making mounts of filesystems from non-initial user namespace safe. Starting with kernel 4.18 it is possible to mount FUSE filesystems in user namespaces. It is expected that overlayfs will follow in future kernel releases. In this talk we will take a closer look at the infrastructure that was added to the kernel, the underlying security mechanisms, and upcoming filesystem that might be available to unprivileged containers in the future. Christian Brauner is a core developer and maintainer of the LXD and LXC projects. He works mostly upstream for Canonical as part of the Ubuntu Server team on the Linux Kernel and lower-level problems. He's been active in the open source community for a long time and is a frequent speaker at various large Linux events; he is also strongly committed to working in the open, and a strong proponent of Free Software. 🤍 🤍containercamp
