Then, I discuss the techniques available to play tricks on our brains in which two slightly (but cleverly) distinct two-dimensional images are presented to our eyes in such a way that our mind conjures up depth where there objectively is none.\r\n\r\nThese techniques come in various forms, from very high tech (such as virtual reality goggles) to very low tech (like mechanical stereoscopic viewers), but some can deal without any projection technology at all: this is called freeviewing, and for most people it is a remarkably simple and low-cost way to enjoy stunning three-dimensional imagery.

Unfortunately, these CODEC implementations do not support the alpha plane that provides transparency. \r\n\r\nIn this talk, Nicolas will introduce the audience to retro alpha support, a workaround specification designed by the Google WebM team to enable VP8 & VP9 to support transparency, and will dive into the architecture he has implemented in GStreamer to support this type of video, both with software decoders and hardware-accelerated V4L2 decoders.", "conf_url": "https://lca2022.linux.org.au/schedule/presentation/43/", "cancelled": false, "twitter_id": "ndufresne" }, { "room": "Kaya Theatre", "rooms": [ "Kaya Theatre" ], "start": "2022-01-16T10:45:00", "end": "2022-01-16T11:30:00", "duration": 45, "kind": "talk", "section": "main", "section_name": "Main Conference", "track": null, "conf_key": 25, "license": "CC-BY-SA", "tags": "", "released": true, "contact": [], "name": "The Security Community Expressed As Too Many Venn Diagrams", "authors": [ { "name": "Casey Schaufler", "twitter": "", "contact": "redacted", "picture_url": "/site_media/media/speaker_photos/CaseyInShrewsbury-2017.JPG.120x120_q85_crop.jpg", "code": "46", "biography": "Casey Schaufler founded the Smack project in 2006 after an especially heated debate with the SELinux developers on a topic now long forgotten.

One of the most popular ways of managing memory is through a garbage collector (GC), which frees memory by regularly deallocating unreferenced data. Optimising programming languages' GC algorithms and implementations can be key to improving the performance of large scale, low-latency and high-throughput systems. However, state-of-the-art GC algorithms can be difficult to implement, which often results in new language designers trading performance for simplicity. Additionally, garbage collectors are often tightly integrated into the language runtime, which makes it difficult for existing languages to optimise their GC or switch to new algorithms altogether.\r\n\r\nIn this talk, we introduce the Memory Management Toolkit (MMTk), an Open Source runtime-agnostic garbage collection framework being developed by researchers at ANU. MMTk provides developers with a large library of high-performance GC algorithms (ranging from tried-and-tested to cutting-edge), exposed behind a unified bidirectional API.

This was followed by more wold-firsts: proofs of security enforcement, proof of correctness of the executable binary, sound worst-case execution-time analysis.\r\nseL4 had been developed and verified at NICTA, a public-sector research organisation, and open-sourced in 2014. With NICTA being absorbed into CSIRO in 2015, the seL4 developers, known as the Trustworthy Systems (TS) team, became part of CSIRO, and research, development and community support continued there, mostly through funding from the US government (DARPA) and industry. However, uptake remained limited outside the defence sector. In April 2020 we created the seL4 Foundation (as a project of the Linux Foundation) as a way to encourage broader community engagement as well as removing dependency on a single organisation.\r\nThe importance of the latter aspect became obvious when in May 2021 CSIRO announced that it was abandoning the Trustworthy Systems group and its research agenda of developing truly secure computer systems. This was a near-death experience for seL4: many of our highly-skilled staff and students had job offers within days. The TS team would have disintegrated within weeks, leaving seL4 orphaned, had not UNSW stepped up and offered to fund the team to the end of the year, giving us much needed breathing space.\r\nThis was followed by an amazing rallying of the community. While before we had trouble scaling Foundation membership beyond the half-dozen initial members, companies we never heard of (but who were already building seL4 into their products) joined, increasing the Foundation's membership revenue ten-fold over a period of about 2 months. Many former staff increased their engagement (with backing from their employers), and community contributions increased massively. At the same time the TS continued to hit new firsts, especially on verification and security proofs for seL4 on 64-bit RISC-V. The technology and its ecosystem are very much alive and growing.\r\nWhich leaves a number of questions to explore, specifically: (1) why did we not achieve more community engagement before the cataclysmic events of May'20, and (2) why did things suddenly take off after?\r\nI can only attempt to provide (at best partial) answers, and will welcome feedback from other community leaders. However it is clear that (1) had to do with the steep learning curve of seL4, but also organisational barriers. Specifically, seL4 development was not really open until we set up the Foundation, and even then it took a long time to move everything out from CSIRO, a process that was still on-going when the divorce was announced. Yet it became clear that there was far more seL4 adaptation in industry than we were aware of. (2) was clearly enabled by this existing activity: people realised that the whole of seL4 was under threat, and they had to contribute back if they wanted it to live on. Which leaves us with the question of what could we have done differently to get them engaged earlier, and how can we engage even more of the adopters?

This model is much safer than writing a custom kernel-module which has high maintenance & can cause kernel-panics/crashes, eBPF does not suffer from these issues as, it has an in-kernel verifier which allows a very restricted set of functionalities. Although, eBPF was earlier targeted at only the network data path, it now has evolved into a framework which can be used in almost everywhere in the kernel. Novel usages include writing TCP congestion control algorithms entirely in user-space and load them to the kernel without having to go through a full kernel release cycle. Apart from the network stack, there are various ad-hoc telemetry data that we can extract from the kernel which can aid in tackling performance problems without modifying the kernel.

The CPU namespace virtualizes the CPU information by maintaining an internal translation from the namespace CPU to the logical CPU in the kernel. The CPU namespace will also enable the existing interfaces interfaces like sys/proc, cgroupfs and sched_set(/get)affinity syscalls to be context aware and divulge information of the topology based on the CPU namespace context that requests information from it.\r\n\r\nThe aim of this talk is to propose a mechanism to isolate CPU topology information from applications that are running in a containerized environment.\r\n\r\nThe potential utilities of having the proposed CPU isolation are as follows:\r\n1. An interface for coherent information:\r\n a. Today, most applications that run on containers enforce their CPU limits requirements with the help of the cgroup interface. Cgroups is a control interface rather than an information interface; hence applications do not have a coherent view of the systems and the restrictions they incur.\r\n b. The problem extends beyond to coherency of information. Cloud runtime environments can requests for CPU runtime in millicores, which translate to using CFS period and quota to limit CPU runtime in cgroups. However, generally, applications operate in terms of threads with little to no cognizance of the millicore limit or its connotation.\r\nThis can lead to unexpected running behaviors as well as have high impact on performance. Hence, having a coherent interface for divulge information based on constraints set by different subsystems is important. \r\n2. Potential security and fair use implications on multi-tenant systems:\r\n a. A case where an actor can be in cognizance of the CPU node topology can schedule workloads and select CPUs such that the bus is flooded causing a Denial Of Service attack.\r\n b. A case wherein identifying the CPU system topology can help identify cores that are close to buses and peripherals such as GPUs to get an undue latency advantage from the rest of the workloads.\r\n\r\nCurrently, all of these problems mentioned above can be mitigated with the use of light weight VMs - Kata Containers. However with the use of a CPU namespace, the isolation advantages that are provided by a Kata Container can be achieved without the heaviness of a virtual machine.\r\n\r\nA survey RFD had been posted here highlighting the problem, its impact and the current solutions that exist in the userspace as well as kernel: https://lore.kernel.org/lkml/fe947175-62f5-c3fa-158c-7be2dd886c0e@linux.ibm.com/T/", "conf_url": "https://lca2022.linux.org.au/schedule/presentation/11/", "cancelled": false, "twitter_id": "pratikrsampat" }, { "room": "Kia Ora Theatre", "rooms": [ "Kia Ora Theatre" ], "start": "2022-01-14T14:40:00", "end": "2022-01-14T15:10:00", "duration": 30, "kind": "talk", "section": "main", "section_name": "Main Conference", "track": "System Administration", "conf_key": 88, "license": "CC-BY-SA", "tags": "", "released": true, "contact": [], "name": "\u201cWhy are they asking me to do this?\u201d or Adventures in IR Land", "authors": [ { "name": "Gyle dela Cruz", "twitter": "GyledC", "contact": "redacted", "picture_url": "https://secure.gravatar.com/avatar/e9188515a748a59e351eca918256d967?s=120&d=mp", "code": "22", "biography": "Gyle has a multi-cultural and multi-disciplinary background.

From roads and footpaths to power lines and fibre-optic cables, we rely on basic foundations to access both utilities and communal spaces. Similarly, much of the Internet is built on top of open-source frameworks that make it easy to develop complex websites and applications.\r\n\r\nNot all of our public infrastructure is easy for people with disabilities to access. However, the Internet is far less accessible than physical public spaces. Various sources have come up with different numbers for 'the percentage of public websites that disabled people can't use'; most are over 50 percent, and depending on the specific disability referenced, some are as high as 98 percent.\r\n\r\nWhat are the barriers that have resulted in that figure being so high? There are quite a few of them, but one important reason is that so much of the modern internet is built on frameworks, plugins, and extensions. In the same way that complex signage in cities stops people with cognitive disabilities from travelling independently, and crumbling sidewalks limit wheelchair users to their homes, inaccessible frameworks create a lot of difficulty for folks with disabilities. Anyone creating a website using them has to do a lot of remediation work if they want the final product to be accessible, and due to time and budget constraints, that work often doesn't happen.\r\n\r\nOf course, provided that they're open-source, anyone can contribute to the common frameworks that power our software. This gives us an opportunity to make improvements that others can leverage, rather than just remediating issues in your own work. However, this requires more than just web development skills.

Gprofng is a standalone tool however and specifically targets Linux. It includes several tools to collect and view the performance data. Various processors from Intel, AMD, and Arm are supported.\r\n\r\nThe focus is on applications written in C, C++, Java, and Scala. For C/C++ we assume gcc has been used to build the code. In the case of Java and Scala, OpenJDK and compatible implementations are supported.\r\n\r\nAmong other things, another difference with the widely known gprof tool is that gprofng offers full support for shared libraries and multithreading using Posix Threads, OpenMP, or Java Threads.\r\n\r\nUnlike gprof, gprofng can also be used in case the source code of the target executable is not available. Gprofng also works with unmodified executables. There is no need to recompile, or instrument the code. By profiling the production executable it is ensured that the profile reflects the actual run time behaviour and conditions of a production run.\r\n\r\nAfter the data has been collected, the performance information can be viewed at the function, source, and disassembly level. Individual thread views are supported as well. Through command line options, the user specifies the information to be displayed. In addition to this, a simple, but yet powerful scripting feature can be used to produce a variety of performance reports in an automated way. This may also be combined with filters to zoom in on specific aspects of the profile. For example, it is very easy to zoom in on one or more threads, but also to compare the behaviour across threads.\r\n\r\nOne of the very powerful features of gprofng is the ability to compare two or more profiles. This allows for an easy way to spot regressions, or find scalability bottlenecks for example.\r\n\r\nIn the talk, we start with a description of the architecture of the gprofng tools suite. This is followed by an overview of the various tools that are available, plus the main features. A comparison with gprof will be made, but the bulk of the talk consists of examples to show the functionality and features. We conclude with the plans for future developments.

\r\n

Donna Benjamin, Nicola Nye, Steven Ellis and Hugh Blemings

\r\n

An annual tradition of linux.conf.au, the Newcomers Session is an opportunity for first time attendees (and those who enjoy coming along year after year...) to find out more about the conference and everything it has to offer.

\r\n

An informal session, it's hosted by a number of folk who have attended one or more (for some, many more) LCAs in the past. Please join us in the Newcomers Session room in Venueless.
