Due to how pid allocation works the kernel is free to recycle PIDs once a process has been reaped. As such, PIDs do not allow another process to maintain a private, stable reference on a process. On systems under pressure it is thus possible that a PID is recycled without other (non-parent) processes being aware of it. This becomes rather problematic when (non-parent) processes are in charge of managing other processes as is the case for system managers or userspace implementations of OOM killers.\n\nOver the last months we have been working on solving these and other problems by introducing pidfds – process file descriptors. Among other nice properties, the allow callers to maintain a private, stable reference on a process.\n\nIn this talk we will look at challenges we faced and the different approaches people pushed for. We will see what already has been implement and pushed upstream, look into various implementation details and outline what we have planned for the future.","original_language":"eng","persons":["Christian Brauner"],"tags":["asg2019","172","2019"],"view_count":261,"promoted":false,"date":"2019-09-21T00:00:00.000+02:00","release_date":"2019-09-21T02:00:00.000+02:00","updated_at":"2025-03-03T02:15:02.490+01:00","length":2574,"duration":2574,"thumb_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/172-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/172-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/172-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/172-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/ASG2019-172-pidfds-process-file-descriptors-on-linux","url":"https://api.media.ccc.de/public/events/355ea6a0-d58b-5a47-a613-312ede6b1859","conference_title":"All Systems Go! 2019","conference_url":"https://api.media.ccc.de/public/conferences/asg2019","related":[{"event_id":7870,"event_guid":"878e4754-c346-5b93-96d2-1ca8bf5109c3","weight":20},{"event_id":7874,"event_guid":"1ea14c32-c58c-513c-ab1f-40ac082e985c","weight":3},{"event_id":7882,"event_guid":"a738a107-7051-544d-98cf-b6c3adce4a3f","weight":21},{"event_id":7883,"event_guid":"40aa2960-6288-5a2f-bf6f-268746f0ecdf","weight":21},{"event_id":7893,"event_guid":"7bc76c4b-311d-55e4-b60e-1c837b15ed7b","weight":20},{"event_id":7910,"event_guid":"b0b3fa50-d9db-511a-9fb1-9edb96bd3401","weight":20}]},{"guid":"04ca5cae-20ff-516b-a362-94c7b2dc5c6a","title":"Yomi - an openSUSE installer based on SaltStack","subtitle":null,"slug":"ASG2019-118-yomi-an-opensuse-installer-based-on-saltstack","link":"https://cfp.all-systems-go.io/ASG2019/talk/KDEYJZ/","description":"We will present [Yomi](https://github.com/openSUSE/yomi), a new proposal for installing Linux using [SaltStack](https://github.com/saltstack/salt).

In this talk, I want to show the most common and biggest problems and possible solutions.\n\nMore and more Linux Distributors have a Distribution using atomic updates to update the system. They all have the problem of updating the files in /etc, as an admin could do changes after the update but before the reboot to activate the updates. But everybody come up with another solution which solves their usecase, but is not generic useable. Additional there is the \"Factory Reset\" of systemd, which no big distribution has really fully implemented today. A unique handling of /etc for atomic updates could also help to convince upstream developers to add support to their applications, while currently they hesitate to add distribution specific patches and support.\n\nDuring this talk, I will describe the different areas of problems and possible solutions. The goal is to provide a concept working for all Linux Distributors (like the FHS). My dream is, that no package installs anything in /etc, it should only contain changes made by the system administrator or configuration files managed by the system administrator.\n\nFor some problems, it would be already enough today if Linux distributors would adjust the configuration of applications or use all features of them. Other requires minimal to intrusive changes to packages, and for the last kind complete new concepts are necessary.","original_language":"eng","persons":["Ignaz Forster"],"tags":["asg2019","119","2019"],"view_count":256,"promoted":false,"date":"2019-09-20T00:00:00.000+02:00","release_date":"2019-09-21T02:00:00.000+02:00","updated_at":"2025-05-21T15:30:06.001+02:00","length":2359,"duration":2359,"thumb_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/119-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/119-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/119-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/119-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/ASG2019-119-atomic-updates-and-configuration-files-in-etc","url":"https://api.media.ccc.de/public/events/9dbd53a6-97d6-55b6-8ef0-e339aae4ff20","conference_title":"All Systems Go! 2019","conference_url":"https://api.media.ccc.de/public/conferences/asg2019","related":[{"event_id":7864,"event_guid":"3d439f1d-e67a-5e92-96b6-3a9c5ad30965","weight":36},{"event_id":7870,"event_guid":"878e4754-c346-5b93-96d2-1ca8bf5109c3","weight":39},{"event_id":7882,"event_guid":"a738a107-7051-544d-98cf-b6c3adce4a3f","weight":36},{"event_id":7883,"event_guid":"40aa2960-6288-5a2f-bf6f-268746f0ecdf","weight":51},{"event_id":7893,"event_guid":"7bc76c4b-311d-55e4-b60e-1c837b15ed7b","weight":24},{"event_id":7910,"event_guid":"b0b3fa50-d9db-511a-9fb1-9edb96bd3401","weight":27},{"event_id":7914,"event_guid":"53354cbe-c92f-5c48-82e3-194690b28f0c","weight":32}]},{"guid":"8617d047-766c-5837-9350-a35c6d29d7cb","title":"Custom cgroup-bpf programs in systemd","subtitle":null,"slug":"ASG2019-144-custom-cgroup-bpf-programs-in-systemd","link":"https://cfp.all-systems-go.io/ASG2019/talk/M8DVWG/","description":"The primary focus is to gather feedback from systemd community regarding ongoing and future work to introduce custom cgroup-bpf programs to systemd.\nThe motivation is to give a user a capability to attach their own cgroup-bpf programs to systemd containers.\n\nThis is a continuation of \u003ca href=\"https://github.com/systemd/systemd/issues/10227\" title=\"discussion\"\u003e started at ASG2018 and followed by \u003ca href=\"https://github.com/systemd/systemd/pull/12151\" title=\"PR12151\"\u003e and \u003ca href=\"https://github.com/systemd/systemd/pull/12419\" title=\"PR12419\"\u003e.\n\nCurrently systemd utilizes BPF macro-assembly which is poorly extendable and maintainable, so the 1st iteration would be introducing `libbpf` library to systemd.

I will dive into the the details of how these builds are performed with systemd-nspawn, how we use the Buck system to define the systemd services and their dependencies, and how these images work at runtime.","original_language":"eng","persons":["Lindsay Salisbury"],"tags":["asg2019","143","2019"],"view_count":100,"promoted":false,"date":"2019-09-21T00:00:00.000+02:00","release_date":"2019-09-21T02:00:00.000+02:00","updated_at":"2025-01-25T11:30:07.547+01:00","length":1539,"duration":1539,"thumb_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/143-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/143-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/143-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/143-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/ASG2019-143-building-portable-service-images-with-buck","url":"https://api.media.ccc.de/public/events/d4f88c04-93ec-56ce-ae97-973a04b96fbd","conference_title":"All Systems Go! 2019","conference_url":"https://api.media.ccc.de/public/conferences/asg2019","related":[{"event_id":7864,"event_guid":"3d439f1d-e67a-5e92-96b6-3a9c5ad30965","weight":1},{"event_id":7865,"event_guid":"9dbd53a6-97d6-55b6-8ef0-e339aae4ff20","weight":1},{"event_id":7870,"event_guid":"878e4754-c346-5b93-96d2-1ca8bf5109c3","weight":7},{"event_id":7871,"event_guid":"4fb36c1f-144d-54a4-b4de-873384e98c40","weight":3},{"event_id":7873,"event_guid":"bc369d82-ced8-535d-a824-32b2efdf9528","weight":1},{"event_id":7876,"event_guid":"2d010334-8e60-5428-b831-b0bf7b3ba6af","weight":1},{"event_id":7877,"event_guid":"0ca00408-9684-58d3-a7c3-7d7b6cae6b75","weight":3},{"event_id":7878,"event_guid":"dcabb3af-fcac-5e83-a77d-5aa655cd95b3","weight":1},{"event_id":7882,"event_guid":"a738a107-7051-544d-98cf-b6c3adce4a3f","weight":7},{"event_id":7883,"event_guid":"40aa2960-6288-5a2f-bf6f-268746f0ecdf","weight":9},{"event_id":7886,"event_guid":"df4ceb70-2c63-538c-b581-e60adc89f261","weight":4},{"event_id":7887,"event_guid":"06a90eaf-78a4-52d6-b29d-ce47622c4955","weight":1},{"event_id":7888,"event_guid":"dad4ba00-7141-5e7d-af7d-02f492f4b5e5","weight":4},{"event_id":7891,"event_guid":"355ea6a0-d58b-5a47-a613-312ede6b1859","weight":1},{"event_id":7893,"event_guid":"7bc76c4b-311d-55e4-b60e-1c837b15ed7b","weight":1},{"event_id":7894,"event_guid":"b9883475-56ad-5749-9c65-e178a1e6bbfb","weight":9},{"event_id":7910,"event_guid":"b0b3fa50-d9db-511a-9fb1-9edb96bd3401","weight":7},{"event_id":7914,"event_guid":"53354cbe-c92f-5c48-82e3-194690b28f0c","weight":4},{"event_id":7918,"event_guid":"147efef1-ba80-5748-9655-fb5cd41f61f9","weight":1},{"event_id":7922,"event_guid":"090131ec-ac5c-5b60-85a0-6d080ea4054c","weight":4},{"event_id":7923,"event_guid":"19b2b529-d037-53ac-8e5e-81028aea4827","weight":1},{"event_id":7930,"event_guid":"71c8ae1e-b22d-4576-9ec8-cc0920ac61a4","weight":1},{"event_id":7934,"event_guid":"6238c286-33b4-4388-9637-9c4024f0d9e8","weight":1},{"event_id":7936,"event_guid":"fc47f807-2b7a-4409-b980-3e12322fe6d5","weight":1}]},{"guid":"b0b3fa50-d9db-511a-9fb1-9edb96bd3401","title":"systemd @ Facebook in 2019","subtitle":null,"slug":"ASG2019-142-systemd-facebook-in-2019","link":"https://cfp.all-systems-go.io/ASG2019/talk/983XHL/","description":"We'll be covering happenings, learnings and new challenges running and supporting systemd in production on the Facebook fleet throughout the past year.\n\nThis talk is a followup to [State of systemd @ Facebook](https://cfp.all-systems-go.io/ASG2018/talk/192/) that was presented last year.

[Traceloop](https://github.com/kinvolk/traceloop) similarly traces system calls but asynchronously in the background, using BPF and tracing per cgroup. I’ll show how it can be integrated with systemd and with Kubernetes via [Inspektor Gadget](https://github.com/kinvolk/inspektor-gadget).\n\nTraceloop's traces are recorded in a fast, in-memory, overwritable ring buffer like a flight recorder. As opposed to “strace”, the tracing could be permanently enabled on systemd services or Kubernetes pods and inspected in case of a crash. This is like a always-on “strace in the past”.\n\nTraceloop uses BPF through the gobpf library. Several new features have been added in gobpf for the needs of traceloop: support for overwritable ring buffers and swapping buffers when the userspace utility dumps the buffer.\n\nhttps://github.com/kinvolk/traceloop\nhttps://github.com/kinvolk/inspektor-gadget\nhttps://github.com/iovisor/gobpf\n\nSlides: https://docs.google.com/presentation/d/1zIZUrTrD7FkS9pHnWz87ZmoLTrO1g9-J_lDMD7E5kdo/edit","original_language":"eng","persons":["Alban Crequy"],"tags":["asg2019","159","2019"],"view_count":94,"promoted":false,"date":"2019-09-20T00:00:00.000+02:00","release_date":"2019-09-21T02:00:00.000+02:00","updated_at":"2024-02-01T20:15:05.128+01:00","length":2250,"duration":2250,"thumb_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/159-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/159-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/159-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/159-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/ASG2019-159-traceloop-for-systemd-and-kubernetes-inspektor-gadget","url":"https://api.media.ccc.de/public/events/2dd3d338-37ae-5b15-8292-1f124c0235a4","conference_title":"All Systems Go! 2019","conference_url":"https://api.media.ccc.de/public/conferences/asg2019","related":[{"event_id":7864,"event_guid":"3d439f1d-e67a-5e92-96b6-3a9c5ad30965","weight":4},{"event_id":7865,"event_guid":"9dbd53a6-97d6-55b6-8ef0-e339aae4ff20","weight":4},{"event_id":7874,"event_guid":"1ea14c32-c58c-513c-ab1f-40ac082e985c","weight":1},{"event_id":7875,"event_guid":"21aca390-bc0c-5eef-a867-1b57a7ee36ab","weight":4},{"event_id":7877,"event_guid":"0ca00408-9684-58d3-a7c3-7d7b6cae6b75","weight":5},{"event_id":7888,"event_guid":"dad4ba00-7141-5e7d-af7d-02f492f4b5e5","weight":6},{"event_id":7890,"event_guid":"8a203dd4-c4d8-51af-b01e-8a199a515c16","weight":3},{"event_id":7894,"event_guid":"b9883475-56ad-5749-9c65-e178a1e6bbfb","weight":7},{"event_id":7910,"event_guid":"b0b3fa50-d9db-511a-9fb1-9edb96bd3401","weight":5},{"event_id":7922,"event_guid":"090131ec-ac5c-5b60-85a0-6d080ea4054c","weight":3},{"event_id":7926,"event_guid":"47ead120-c630-5091-bf6e-5b72c6f98ec8","weight":5}]},{"guid":"fd85bb93-e67e-5ecc-ad41-8470024119fe","title":"The state of Thunderbolt on GNU/Linux","subtitle":null,"slug":"ASG2019-150-the-state-of-thunderbolt-on-gnu-linux","link":"https://cfp.all-systems-go.io/ASG2019/talk/HXLJNF/","description":"A summary of the current state of Thunderbolt, kernel as well as user space, including the latest development where the the input–output memory management unit (IOMMU) is used to prevent Direct Memory Access (DMA) attacks.

Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them.\n\nGNU poke is a new interactive editor for binary data.  Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them.  Once a user has defined a structure for binary data (usually matching some file format) she can search, inspect, create, shuffle and modify abstract entities such as ELF relocations, MP3 tags, DWARF expressions, partition table entries, and so on, with primitives resembling simple editing of bits and bytes.  The program comes with a library of already written descriptions (or \"pickles\" in poke parlance) for many binary formats.\n\nGNU poke is useful in many domains.  It is very well suited to aid in the development of programs that operate on binary files, such as assemblers and linkers.  This was in fact the primary inspiration that brought me to write it: easily injecting flaws into ELF files in order to reproduce toolchain bugs.  Also, due to its flexibility, poke is also very useful for reverse engineering, where the real structure of the data being edited is discovered by experiment, interactively.  It is also good for the fast development of prototypes for programs like linkers, compressors or filters, and it provides a convenient foundation to write other utilities such as diff and patch tools for binary files.\n\nThis talk (unlike Gaul) is divided into four parts.  First I will introduce the program and show what it does: from simple bits/bytes editing to user-defined structures.  Then I will show some of the internals, and how poke is implemented.  The third block will cover the way of using Poke to describe user data, which is to say the art of writing \"pickles\".  The presentation ends with a status of the project, a call for hackers, and a hint at future works.","original_language":"eng","persons":["Jose E.

This includes a CGEN cpu description, assembler, disassembler and linker.  By the time of the conference a simulator will be available as well, along with GDB support. A GCC backend will be submitted for inclusion upstream before September.\n\nThe first part of the talk will be a brief general description of the project, its components, what motivated us to start working on it, and an update on the project's status at the time of the conference.\n\nThen we will discuss the particular challenges of supporting a target like eBPF:\n\nOn one hand, the kernel virtual machine has some unique characteristics that have a definitive impact on the tooling, like the in-kernel validator and the specialized contexts in which eBPF programs run.  We will show how the tools can help improving the eBPF programmer's experience.\n\nOn the other hand, the exact shape of compiled eBPF code is still subject to change, and is in fact rapidly changing and evolving.  Initially quite simple in terms of toolchain needs (single compilation units, no linking) this is changing as more kernel systems are being changed/written to be based on eBPF, and as the in-kernel validator is becoming more and more sophisticated.  Along with bigger and more complex programs comes the need for more abstraction, hence modularity and code reuse.

This talk covers past, present, and future development along with possible plans for systemd integration.\n\nRunning out of memory on a host is a particularly nasty scenario. In the Linux kernel, if memory is being overcommitted, it results in the kernel out-of-memory (OOM) killer kicking in. Perhaps surprisingly, the kernel does not often handle this well. oomd builds on top of recent kernel development to effectively implement OOM killing in userspace. This results in a faster, more predictable, and more accurate handling of OOM scenarios.\n\noomd has gained a number of new features and interesting deployments in the last year. The most notable feature is a complete redesign of the control plane which enables arbitrary but \"gotcha\"-free configurations. In this talk, Daniel Xu will cover past, present, future, and path-not-taken development plans along with experiences gained from overseeing large deployments of oomd.

The challenges to run diskless in the context of blockchain hashing for cryptocurrencies are different. There are constraints like to run sufficiently on hundreds of machines with commodity 1 Gbit/s network hardware or the modest RAM size of 4 Gigabyte. This talk will provide insights in the technical approaches that made it possible to run GPU-clusters for blockchain hashing diskless and provide an outlook to  other potential GPU-based use cases beyond blockchain hashing.\nI will discuss like how some early userspace trickery and state of the art RAM compression is used. How to handle the modest given RAM size and how a neat toolset based on container-runtimes helps to easily build boot images and plug-in packages. And how to use plug-in packages as an elegant way for adding further software like proprietary GPU drivers to the computing nodes of the clusters.","original_language":"eng","persons":["Gunter Miegel"],"tags":["asg2019","141","2019"],"view_count":91,"promoted":false,"date":"2019-09-21T00:00:00.000+02:00","release_date":"2019-09-21T02:00:00.000+02:00","updated_at":"2025-01-21T09:15:07.125+01:00","length":1434,"duration":1434,"thumb_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/141-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/141-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/141-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/141-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/ASG2019-141-coinboot-cost-effective-diskless-gpu-clusters-for-blockchain-hashing-and-beyond","url":"https://api.media.ccc.de/public/events/3c8f6eff-42ef-5c5d-abfd-00fb58b4d6e8","conference_title":"All Systems Go! 2019","conference_url":"https://api.media.ccc.de/public/conferences/asg2019","related":[{"event_id":7869,"event_guid":"8f67b425-117b-5575-839f-f6d9e3604f3a","weight":3},{"event_id":7870,"event_guid":"878e4754-c346-5b93-96d2-1ca8bf5109c3","weight":4},{"event_id":7876,"event_guid":"2d010334-8e60-5428-b831-b0bf7b3ba6af","weight":4},{"event_id":7878,"event_guid":"dcabb3af-fcac-5e83-a77d-5aa655cd95b3","weight":3},{"event_id":7883,"event_guid":"40aa2960-6288-5a2f-bf6f-268746f0ecdf","weight":5},{"event_id":7884,"event_guid":"0caaa7aa-f6bd-55ba-8ccc-e698afa5c9df","weight":3},{"event_id":7889,"event_guid":"d4f88c04-93ec-56ce-ae97-973a04b96fbd","weight":4},{"event_id":7890,"event_guid":"8a203dd4-c4d8-51af-b01e-8a199a515c16","weight":3},{"event_id":7894,"event_guid":"b9883475-56ad-5749-9c65-e178a1e6bbfb","weight":3},{"event_id":7895,"event_guid":"259c3989-a0c3-57a0-8515-c10f29613830","weight":3},{"event_id":7910,"event_guid":"b0b3fa50-d9db-511a-9fb1-9edb96bd3401","weight":6}]},{"guid":"53354cbe-c92f-5c48-82e3-194690b28f0c","title":"Boot Loader Specification + sd-boot","subtitle":null,"slug":"ASG2019-163-boot-loader-specification-sd-boot","link":"https://cfp.all-systems-go.io/ASG2019/talk/HFJMLU/","description":"The boot loader specification defines a generic drop-in based solution for defining boot targets. sd-boot is a boot loader for UEFI systems, and included in the systemd source tree.

In this talk, we will demonstrate a solution to this problem that we plan to propose for standardisation within the Open Container Initiative (code-named \"OCIv2 images\").\n\nThis talk is specific to the Open Container Initiative's image specification, but the same techniques could be applied to other systems (though we'd obviously recommend using OCI). \n\nIn order to avoid the [numerous issues with tar archives](https://www.cyphar.com/blog/post/ociv2-images-i-tar) it is necessary to come up with a different format. In addition, layer representations result in needless wasted space for storage of files which are no longer relevant to running containers. Massive amounts of duplication are also rampant within OCI images because tar archives are completely opaque to OCI's content-addressable store.\n\nLuckily the problem of representing a container root filesystem for distribution is very similar to existing problems within backup systems, and we can take advantage of prior art such as [restic](https://restic.net/) to show us how we can get significant space-savings and possibly efficiency savings.\n\nHowever, we also must ensure that the runtime cost of using this new system is equivalent to existing container images. Container images are efficient at runtime because they map directly to how overlay filesystems represent change-sets as layers, but with some tricks it is possible for us to obtain most of the improvements we also gained in distribution with de-duplication.\n\nOur proposed solution to all of these problems will be laid out, with opportunities for feedback and discussion.","original_language":"eng","persons":["Aleksa Sarai"],"tags":["asg2019","123","2019"],"view_count":376,"promoted":false,"date":"2019-09-21T00:00:00.000+02:00","release_date":"2019-09-21T02:00:00.000+02:00","updated_at":"2025-05-11T13:30:04.545+02:00","length":2327,"duration":2327,"thumb_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/123-hd.jpg","poster_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/123-hd_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/123-hd.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/all_systems_go/2019/123-hd.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/ASG2019-123-ociv2-container-images-considered-harmful","url":"https://api.media.ccc.de/public/events/b9883475-56ad-5749-9c65-e178a1e6bbfb","conference_title":"All Systems Go! 2019","conference_url":"https://api.media.ccc.de/public/conferences/asg2019","related":[{"event_id":7864,"event_guid":"3d439f1d-e67a-5e92-96b6-3a9c5ad30965","weight":10},{"event_id":7865,"event_guid":"9dbd53a6-97d6-55b6-8ef0-e339aae4ff20","weight":8},{"event_id":7870,"event_guid":"878e4754-c346-5b93-96d2-1ca8bf5109c3","weight":15},{"event_id":7875,"event_guid":"21aca390-bc0c-5eef-a867-1b57a7ee36ab","weight":2},{"event_id":7880,"event_guid":"8617d047-766c-5837-9350-a35c6d29d7cb","weight":1},{"event_id":7881,"event_guid":"faa5c5e3-6a1e-5c6d-bd90-eb270142ec6e","weight":7},{"event_id":7882,"event_guid":"a738a107-7051-544d-98cf-b6c3adce4a3f","weight":10},{"event_id":7883,"event_guid":"40aa2960-6288-5a2f-bf6f-268746f0ecdf","weight":17},{"event_id":7884,"event_guid":"0caaa7aa-f6bd-55ba-8ccc-e698afa5c9df","weight":2},{"event_id":7886,"event_guid":"df4ceb70-2c63-538c-b581-e60adc89f261","weight":1},{"event_id":7888,"event_guid":"dad4ba00-7141-5e7d-af7d-02f492f4b5e5","weight":8},{"event_id":7891,"event_guid":"355ea6a0-d58b-5a47-a613-312ede6b1859","weight":1},{"event_id":7893,"event_guid":"7bc76c4b-311d-55e4-b60e-1c837b15ed7b","weight":10},{"event_id":7895,"event_guid":"259c3989-a0c3-57a0-8515-c10f29613830","weight":13},{"event_id":7910,"event_guid":"b0b3fa50-d9db-511a-9fb1-9edb96bd3401","weight":15},{"event_id":7922,"event_guid":"090131ec-ac5c-5b60-85a0-6d080ea4054c","weight":2},{"event_id":7926,"event_guid":"47ead120-c630-5091-bf6e-5b72c6f98ec8","weight":10}]},{"guid":"0ca00408-9684-58d3-a7c3-7d7b6cae6b75","title":"Revamping libcontainer's systemd driver","subtitle":null,"slug":"ASG2019-151-revamping-libcontainer-s-systemd-driver","link":"https://cfp.all-systems-go.io/ASG2019/talk/YPU3HL/","description":"In this talk, I'll go through my efforts to revamp libcontainer's systemd driver, in particular to support the unified cgroup hierarchy.\n\nlibcontainer is part of runc (opencontainers/runc in GitHub) and is used by the Docker and containerd ecosystem to spawn containers.
