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

rust-vmm sync meetings

?Hey everyone, In the last sync meeting Sebastien (in CC) proposed to move all occurrences of the rust-vmm meeting at the same hour. He proposed we use the US friendly time as it has more attendees, and having meetings at irregular times is confusing. [Context: the rust-vmm sync meetings occur every 2 weeks on Monday, with one meeting at an European-friendly hour (11:00 AM to 12:00 PM EEST), and one at an US-friendly hour (6:00 PM to 7:00 PM EEST)]. I wanted to check with you what do you think about this proposal. If nobody is opposing this, I will send an invite with the new time. Next European-friendly meeting is on ?July 26, so it would be nice to reach a decision by July 19 to give people enough time to clear their calendars (if needed). BTW, you can check the meeting notes & agenda here: https://etherpad.opendev.org/p/rust-vmm-sync-2021? Thanks, Andreea Amazon Development Center (Romania) S.R.L. registered office: 27A Sf.
