[TLDR: I'm adding the regression report below to regzbot, the Linux kernel regression tracking bot; all text you find below is compiled from a few templates paragraphs you might have encountered already already from similar mails.] Hi, this is your Linux kernel regression tracker speaking. CCing the regression mailing list, as it should be in the loop for all regressions, as explained here: https://www.kernel.org/doc/html/latest/admin-guide/reporting-issues.html On 21.02.22 23:37, Maxim Levitsky wrote: > Today I updated to a new kernel and I am bisecting few regressions: > > I noticed that if I open GNOME's bluetooth setting, it hangs for like minute or so, > and then shows only the paired devices and no scan results. > > I bisected this to this commit. > > For reference I am running fairly old fedora 32 on this machine, and thus I have > bluez 5.55 and stock GNOME from fedora 32. > > I can provide any more info on anything if required and/or test patches. > > I wasn't able tor revert this commit as it is part of a bigger rewrite of scanning > which makes sense. > > I tried merging bluetooth-next master as of today, > into my kernel but no noticeable improvement. Thanks for the report. To be sure this issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking bot: #regzbot ^introduced e8907f76544ffe225ab95d70f73 #regzbot title bluetooth: scanning stopped working #regzbot ignore-activity Reminder for developers: when fixing the issue, please add a 'Link:' tags pointing to the report (the mail quoted above) using lore.kernel.org/r/, as explained in 'Documentation/process/submitting-patches.rst' and 'Documentation/process/5.Posting.rst'. This allows the bot to connect the report with any patches posted or committed to fix the issue; this again allows the bot to show the current status of regressions and automatically resolve the issue when the fix hits the right tree. I'm sending this to everyone that got the initial report, to make them aware of the tracking. I also hope that messages like this motivate people to directly get at least the regression mailing list and ideally even regzbot involved when dealing with regressions, as messages like this wouldn't be needed then. Don't worry, I'll send further messages wrt to this regression just to the lists (with a tag in the subject so people can filter them away), if they are relevant just for regzbot. With a bit of luck no such messages will be needed anyway. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I'm getting a lot of reports on my table. I can only look briefly into most of them and lack knowledge about most of the areas they concern. I thus unfortunately will sometimes get things wrong or miss something important. I hope that's not the case here; if you think it is, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight. -- Additional information about regzbot: If you want to know more about regzbot, check out its web-interface, the getting start guide, and the references documentation: https://linux-regtracking.leemhuis.info/regzbot/ https://gitlab.com/knurd42/regzbot/-/blob/main/docs/getting_started.md https://gitlab.com/knurd42/regzbot/-/blob/main/docs/reference.md The last two documents will explain how you can interact with regzbot yourself if your want to. Hint for reporters: when reporting a regression it's in your interest to CC the regression list and tell regzbot about the issue, as that ensures the regression makes it onto the radar of the Linux kernel's regression tracker -- that's in your interest, as it ensures your report won't fall through the cracks unnoticed. Hint for developers: you normally don't need to care about regzbot once it's involved. Fix the issue as you normally would, just remember to include 'Link:' tag in the patch descriptions pointing to all reports about the issue. This has been expected from developers even before regzbot showed up for reasons explained in 'Documentation/process/submitting-patches.rst' and 'Documentation/process/5.Posting.rst'.
