Pre-upload SRU review for the principle of this update 2.11 is ahead of Debian. The development release in Ubuntu only got this support in July. This does not give me confidence that this is well tested in the field, whether in Ubuntu or in the wider ecosystem. In particular for wifi, there are compatibility concerns with a very wide range of hardware out there.
> that will test the compatibility with MLO Will you be testing *actual* function with MLO? If this is the reason for the proposed SRU, I think you should be testing MLO extensively in real world situations. What about the test matrix for the various different wifi authentication arrangements that wpa supports? > The kernel is compatible with these since 24.04 (Noble) Which kernel? The release kernel, HWE kernel or both? Your test plan needs to be specific and comprehensive on kernel testing. For _microrelease_ SRUs, we require: https://documentation.ubuntu.com/sru/en/latest/reference/requirements/#new- upstream-microreleases Since this is a feature change, I'd expect something that like to be a requirement, too. For wpa, a test suite seems difficult, but I think it's worth analysing upstream code quality and quality history and what they do manage in lieu of that. The previous 2:2.10- *24* is a red flag here. > [ Where problems could occur ] A really big one here is that if we break a user, it is likely to be very difficult for them to update to a regression fix with their wifi broken. A second one is that wifi configuration and hardware and therefore our required compatibility matrix is much more varied than with an average SRU. I'm not completely opposed to an SRU for this in Noble's lifetime, but it seems premature at the moment. Perhaps doing this in noble-backports first would be a good start, so that users can opt-in, and we'll get a better picture of real world impact before risking wider regression across all users? The last thing we want is a wide swathe of users having wifi problems due to a hardware or configuration compatibility issue we didn't know about. Given the current status of deployment of 2.11 across the ecosystem, I don't think testing five hopefully different configurations is enough. I mentioned earlier elsewhere that adding Wifi 7 sounds like a hardware enablement. It does sound like something users might consider to be towards the end of Noble's lifetime. But right now, I don't see much of a compelling case for improvements in UX for Noble here, when balanced against the risk. ** Summary changed: - Upgrade to 2.11 + No Wifi 7 MLO support -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2117497 Title: No Wifi 7 MLO support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/wpa/+bug/2117497/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
