Containers and Checkpoint/Restore MC Accepted into 2019 Linux Plumbers Conference

We are pleased to announce that the Containers and Checkpoint/Restore Microconference has been accepted into the 2019 Linux Plumbers Conference! Even after the success of last year’s Containers Microconference, there’s still more to work on this year.

Last year had a security focus that featured seccomp support and LSM namespacing and stacking, but now the need to look at the next steps and sets of blockers for those needs to be discussed.

Since last year’s Linux Plumbers in Vancouver, binderfs has been accepted into mainline, but more work is needed in order to fully support Android containers.

Another improvement since Vancouver is that shiftfs is now functional and included in Ubuntu, however, more work is required (including changes to VFS) before shiftfs can be accepted into mainline.

CGroup V2 is an ongoing task needing more work, with one topic of particular interest being feature parity with V1.

Additional important discussion topics include:

  • Even better container security
  • New namespaces (time, logging, …)
  • Adoption and improvement of the new mount and pidfd APIs
  • Speeding up container live migration.

Come join us and participate in the discussion on what holds “The Cloud” together.

Distribution Kernels Microconference Accepted into 2019 Linux Plumbers Conference

We are pleased to announce that the Distribution Kernels Microconference has been accepted to the 2019 Linux Plumbers Conference. This is the
first time Plumbers has offered a microconference focused on kernel distribution collaboration.

Linux distributions come in many forms, ranging from community run distributions like Debian and Gentoo, to commercially supported ones offered by SUSE or Red Hat, to focused embedded distributions like Android or Yocto. Each of these distributions maintains a kernel, making choices related to features and stability. The focus of this track is on the pain points distributions face in maintaining their chosen kernel and common solutions every distribution can benefit from.

Example topics include:

  • Backporting kernel patches and how to make it easier
  • Consuming the stable kernel trees
  • Automated testing for distributions
  • Managing ABIs
  • Distribution packaging/infrastructure
  • Cross distribution bug reporting and tracking
  • Common distribution kconfig
  • Distribution default settings
  • Which patch sets are distributions carrying?

“Distribution kernel” is used in a very broad manner. If you maintain a kernel tree for use by others, we welcome you to come and share your experiences.

Here is a list of proposed topics. For Linux Plumbers 2019, new topics for microconferences can be submitted via the Call for Proposals (CfP) interface. Please visit the CfP page for more information.

Linux Plumbers Earlybird Registration Quota Reached, Regular Registration Opens 30 June

A few days ago we added more capacity to the earlybird registration quota, but that too has now filled up, so your next opportunity to register for Plumbers will be Regular Registration on 30 June … or alternatively the call for presentations to the refereed track is still open and accepted talks will get a free pass.

Quotas were added a few years ago to avoid the entire conference selling out months ahead of time and accommodate attendees whose approval process takes a while or whose company simply won’t allow them to register until closer to the date of the conference.

Additional early bird slots available for LPC 2019

The Linux Plumbers Conference (LPC) registration web site has been showing “sold out” recently because the cap on early bird registrations
was reached. We are happy to report that we have reviewed the registration numbers for this year’s conference and were able to open more early bird registration slots. Beyond that, regular registration will open July 1st. Please note that speakers and microconference runners get free passes to LPC, as do some microconference presenters, so that may be another way to attend the conference. Time is running out for new refereed-track and microconference proposals, so visit the CFP page soon. Topics for accepted microconferences are welcome as well.

LPC will be held in Lisbon, Portugal from Monday, September 9 through Wednesday, September 11.

We hope to see you there!

Tracing Microconference Accepted into 2019 Linux Plumbers Conference

We are pleased to announce that the Tracing Microconference has been accepted into the 2019 Linux Plumbers Conference! Its return to Linux Plumbers shows that tracing is not finished in Linux, and there continue to be challenging problems to solve.

There’s a broad list of ways to perform Tracing in Linux. From the original mainline Linux tracer, Ftrace, to profiling tools like perf, more complex customized tracing like BPF and out-of-tree tracers like LTTng, systemtap, and Dtrace. Part of the trouble with tracing within Linux is that there is so much to choose from. Each of these have their own audience, but there is a lot of overlap. This year’s theme is to find those common areas and combine them into common utilities.

There is also a lot of new work that is happening and discussions between top maintainers will help keep everyone in sync, and provide good direction for the future.

Expected topics include:

  • bpf tracing – Anything to do with BPF and tracing combined
  • libtrace – Making libraries from our tools
  • Packaging – Packaging these libraries
  • babeltrace – Anything that we need to do to get all tracers talking to each other
  • Those pesky tracepoints – How to get what we want from places where trace events are taboo
  • Changing tracepoints – Without breaking userspace
  • Function tracing – Modification of current implementation
  • Rewriting of the Function Graph tracer – Can kretprobes and function graph tracer merge as one
  • Histogram and synthetic tracepoints – Making a better interface that is more intuitive to use

Come and join us and not only learn but help direct the future progress of tracing inside the Linux kernel and beyond!

Here is a list of proposed tracing topics. For Linux Plumbers 2019, new topics for microconferences can be submitted via the Call for Proposals (CfP) interface. Please visit the CfP page for more information.

We hope to see you there!

RISC-V microconference accepted for the 2019 Linux Plumbers Conference

The open nature of the RISC-V ecosystem has allowed contributions from both academia and industry leading to an unprecedented number of new hardware design proposals in a very short time span. Linux support is the key to enabling these new hardware options. Since last year’s Plumbers, many kernel features were added to RISC-V. To name a few, we now have out-of-box 32-bit and eBPF support, some key issues with Linux boot process have been addressed, and hypervisor support is on its way.

Last year’s RISC-V microconference was such a success that we would like to repeat that again this year by focusing on finding solutions and discussing ideas that require kernel changes.

Topics for this year microconference are expected to cover:

  • RISC-V Platform Specification Progress, including some extensions such as power management
  • Fixing the Linux boot process in RISC-V (RISC-V now has better support for open source boot loaders like U-Boot and coreboot compared to last year. As a result of this developers can use the same boot loaders to boot Linux on RISC-V as they do in other architectures, but there’s more work to be done)
  • RISC-V hypervisor emulation
  • NOMMU Linux for RISC-V
  • Any other subject of interest

If you’re interested in participating in this microconference, please contact Atish Patra (atish.patra@wdc.com) or Palmer Dabbelt (palmer@dabbelt.com) . For Linux Plumbers 2019, new topics for microconferences can be submitted via the Call for Proposals (CfP) interface. Please visit the CfP page for more information.

LPC will be held in Lisbon, Portugal from Monday, September 9 through Wednesday, September 11.

We hope to see you there!

BPF microconference accepted into 2019 Linux Plumbers Conference

We are pleased to announce that the BPF microconference has been accepted into the 2019 Linux Plumbers Conference! Last year’s BPF microconference was such a success that it will be held again this year.

BPF along with its just-in-time (JIT) compiler inside the Linux kernel allows for versatile programmability of the kernel and plays a major role in networking (XDP, tc BPF, etc.), tracing (kprobes, uprobes, tracepoints) and security (seccomp, landlock) subsystems.

Since last year’s Plumbers Conference, many of the discussed improvements have been tackled and found their way into the Linux kernel such as significant steps towards allowing for a compile-once paradigm with the help of BTF and global data support as well as considerable verifier scalability improvements to name a few. The topics proposed for this year’s event include:

– libbpf, loader unification
– Standardized BPF ELF format
– Multi-object semantics and linker-style logic for BPF loaders
– Verifier scalability work towards 1 million instructions
– Sleepable BPF programs
– BPF loop support
– Indirect calls in BPF
– Unprivileged BPF
– BPF type format (BTF)
– BPF timers
– bpftool
– LLVM BPF backend, JITs and BPF offloading
– and more

Come join us and participate in the decision making of one of the most cutting edge advancements in the Linux kernel!

See here for a detailed preview of the proposed and accepted topics. For Linux Plumbers 2019, new topics for microconferences can be submitted
via the Call for Proposals (CfP) interface. Please visit the CfP page for more information.

We hope to see you there!

Linux Plumbers Conference 2019 Call for Bird of a Feather (BoF) Session Proposals

On the heels of the previous announcements, we are also pleased to announce the Bird of a Feather (BoF) Session Proposals for the 2019 edition of the Linux Plumbers Conference, which will be held in Lisbon, Portugal on September 9-11 in conjunction with the Linux Kernel Maintainer Summit.

BoFs are free-form get-togethers for people wishing to discuss a particular topic. As always, you only need to submit proposals for BoFs you want to hold on-site. In contrast, and again as always, informal BoFs may be held at local drinking establishments or in the “hallway track” at your convenience.

For more information on submitting a BoF session proposal, see the following:

https://www.linuxplumbersconf.org/event/4/abstracts

Please note that the submission system is the same as 2018. If you created an user account last year, you will be able to re-use the same credentials to submit and modify your proposal(s) this year.

The call for Microconferences and Refereed-Track proposals are also open, and we hope to see you in Lisbon this coming September!
