interest in other Unixes?

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

Fwd: vPTG October 2023 Team Signup Kickoff
by Kendall Nelson 23 Jul '23

23 Jul '23

Hi Everyone, Hopefully, you have seen by now that the next OpenInfra vPTG[1] which will take place October 23-27, 2023 virtually and registration is open[2]! *To sign up your team, you must complete the survey[3] by August 20th at 7:00 UTC.* We NEED accurate contact information (email and IRC nickname ideally) for the moderator of your team’s sessions. This is because the survey information will be used to organize the schedule sign ups which will be done via the PTGBot. If you are not on IRC, please get setup[4] on the OFTC network and join #openinfra-events. You are also encouraged to familiarize yourself with the PTGBot documentation[5] as well. If you have any questions, please reach out! Information about signing up for time will be sent to moderators late August after the interest survey deadline on August 20. -Kendall (diablo_rojo) [1] PTG Site: https://openinfra.dev/ptg/ [2] PTG Registration: http://ptg2023.openinfra.dev/ [3] Team Survey: https://openinfrafoundation.formstack.com/forms/oct2023_ptg_team_signup [4] Setup IRC: https://docs.openstack.org/contributors/common/irc.html [5] PTGBot README: https://opendev.org/openstack/ptgbot/src/branch/master/README.rst

[administrivia] Recent spam-posting subscriber and the held message queue
by Jeremy Stanley 11 Jul '23

11 Jul '23

I noticed someone subscribed to this list earlier today and then sent half a dozen spam posts. I've unsubscribed them and deleted their posts from the archive, but if this continues we may want to consider adjusting the new member policy for the list. For example, we can make it so that anyone else who subscribes from now on will have their posts moderated until a moderator sets that new subscriber as allowed to post unmoderated, once they've demonstrated that they're here for the intended topics of discussion. Unrelated, I checked the moderator queue and see quite a few held posts which look legitimate (presumably because Andreea is on sabbatical and there are no other active moderators for this list), so I'm going to approve them through to the list now and set myself as a stand-in moderator while we seek additional volunteers for the task. -- Jeremy Stanley
