interest in other Unixes?
by Allison Randal 31 Aug '23

Hi all, How interested would you be in patches for Unix family operating systems other than Linux? I'm working on a prototype lightweight VMM on the Illumos Kernel and Bhyve ioctl interface, and I'm planning to reuse rust-vmm libraries where I can. I prefer to work upstream on shared libraries, but I totally understand if the focus here is Linux, and patches for other Unix family operating systems are undesirable. As a concrete example of how non-disruptive this can be, the patch I'm debating whether to submit is a 4 line substitution in vmm-sys-util, which changes [#cfg(unix)] to [#cfg(linux)]. Right now, those lines are checking for target_family = "unix", but the code in question is actually unique to Linux, and fails to compile on other Unix family operating systems (mostly due to type errors, and using features that only exist on Linux), so it really should be checking target_os = "linux" instead. The specific changes are lines 8, 17, and 19, in src/lib.rs, which determine whether to use the code in the architecture-specific 'unix' directory, and whether to use the bitflags library (which is only used by the 'unix' directory). And, line 183 in src/errno.rs testing a very specific string message as the text for libc::EBADF, which has slightly different wording on other Unix family operating systems. That simple substitution makes it possible to use both vmm-sys-util and vm-memory on Illumos (since vm-memory was only using architecture-independent parts of vmm-sys-util for temp files in tests, and nothing in the 'unix' directory). I haven't started systematically testing other rust-vmm libraries for non-Linux compatibility yet, but I expect I'll find similar patterns. (Full disclosure: I personally prefer Linux Kernel and KVM, but this is paid work, and sparks enough intellectual curiosity for me to be willing to do it.) Thanks for any thoughts, Allison

Licensing Issue in rust-vmm crates
by Andreea Florescu 06 Jul '22

06 Jul '22

[Resending this email from my personal email address as it seems like my other email got into spam for most of you :(] Hey folks, afaria(a)redhat.com reported an issue [1] with the license of some of the rust-vmm crates. In our first rust-vmm meetup we decided the license for the crates to be BSD-3-Clause OR Apache 2.0 (as it's also specified in the meeting notes available here [2]), but when we did the implementation of the crate it looks like we wrote the license for some of the files and crates as "Apache-2.0 AND BSD-3-Clause" instead. This license is unfortunately incompatible with projects such QEMU, and makes the rust-vmm crates impossible to use. With this email I would like to get your agreement to update the license to one that is compatible with QEMU and the other known customers of rust-vmm. One thing that we need to discuss is what the license should be. As there is code in vmm-sys-util coming directly from Crosvm I don't think a Apache 2.0 OR BSD-3-Clause license is appropriate because from my understanding this would require the Crosvm code to be re-licensed as Apache 2.0 OR BSD-3-Clause as well. I would like to propose to re-license it as BSD-3-Clause as this is compatible with the licenses of all projects. More details about the specific files where this is a problem are available in the issue [1]. Thanks, Andreea [1] https://github.com/rust-vmm/vmm-sys-util/issues/161 [2] http://lists.opendev.org/pipermail/rust-vmm/2019-May/000200.html

This is because the survey information will be used to organize the schedule signups which will be done via the PTGBot. If you are not on IRC, please get setup[2] on the OFTC network and join #openinfra-events. You are also encouraged to familiarize yourself with the PTGBot documentation[3] as well. If you have any questions, please reach out! Information about signing up for timeslots will be sent to moderators mid to late August. Registration will open soon! A discounted room block at the PTG venue will be available. Continue to visit openinfra.dev/ptg for updates. -Kendall (diablo_rojo) [1] Team Survey: https://openinfrafoundation.formstack.com/forms/oct2022_ptg_team_signup [2] Setup IRC: https://docs.openstack.org/contributors/common/irc.html [3] PTGBot README: https://opendev.org/openstack/ptgbot/src/branch/master/README.rst

2022 Grace Hopper Celebration Open Source Day - Call for Projects
by Open Source Day AnitaB GHC 08 Jun '22

08 Jun '22

*Hello,We're excited to announce that the 2022 Grace Hopper Celebration Open Source Day is open for projects <https://bit.ly/osd22-cfp>!Open Source Day (OSD) is an all-day hack-a-thon at Grace Hopper Celebration in which participants of all levels contribute and learn about Open Source while working on projects designed to solve real-world problems. OSD provides an opportunity for attendees of all skill levels and backgrounds to learn and experience open source contributions with the support of project maintainers, experienced mentors, and expert speakers, providing a fast track to becoming open source contributors.This year, OSD will be a virtual pre-event before the Grace Hopper Celebration, scheduled for Friday, September 16, 2022, from 8:00am to 3:00pm U.S. Pacific Time.If you're an open source project maintainer, we invite you to submit your project to be part of Open Source Day 2022!OSD provides a great way for open source project maintainers to promote your project, earn new contributors, and improve overall health of your project. In addition, you will take part in the movement to increase diversity in open source! According to the 2021 Linux foundation DEI Survey report <https://www.linuxfoundation.org/wp-content/uploads/LFResearch_DEISurvey_Rep…>, only 14% of open source participants identify as women and 4% as non-binary or third gender and other estimates are a lot lower. Join us and be part of the change!CFP link: https://bit.ly/osd22-cfp-projects <https://bit.ly/osd22-cfp-projects>One of the big focuses of Open Source Day is highlighting women open source maintainers. If you are aware of any open source projects with women maintainers whom you think are a great fit for this opportunity, please forward this announcement to them.Note: Selected project maintainers will receive a complimentary virtual ticket to the 2022 Grace Hopper Celebration.Best regards,The Open Source Day Team* -- The Open Source Day Team

Moderation queue flushed
by Jeremy Stanley 01 Jun '22

01 Jun '22

Just a heads up that I flushed some several dozen messages which were waiting for a moderator to approve, so if you received a sudden flood of messages for the ML (some dating back to February), that's why. The majority were held because they were being sent from or cross-posted by people who aren't subscribed to this list, or because they had very large recipient lists (>10 addresses), or were over the default 40KB size limit. On a related note, if anyone is interested in helping check the moderation queue for this list regularly, please let me know. -- Jeremy Stanley
