Maybe you have some funky hardware in your machine that needs a quirk. Regards Marcel

I asked, because I see no hint that anything goes wrong.

My suspicion is that the use_ll_privacy check is the wrong one here. It only checks if hardware feature is available, not if it is also enabled. Regards Marcel

Corrupted white-space issues aside, yes, it works! I am running 5.9-rc8 with just this change on it and my tracball works just fine. > My suspicion is that the use_ll_privacy check is the wrong one here. It only checks if hardware feature is available, not if it is also enabled. How would one go about enabling such a hardware feature if they wanted to? :) Anyway, feel free to put: Tested-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> on the above patch and hopefully get it to Linus for 5.9-final. thanks, greg k-h

The trace file gives it away. So my suspicion is that the device you want to connect to uses RPA (aka random addresses). And we added support for resolving them in the firmware. Your hardware does support that, but the host side is not fully utilizing it and thus your device is filtered out. If I am not mistaken, then the use_ll_privacy() check in these two specific places need to be replaced with LL Privacy Enabled check. And then the allow_rpa condition will do its job as expected. We can confirm this if you send me a trace with the patch applied. Anyhow, if my suspicion is correct, then I just need to figure out on how we fix this for 5.9-rc8 and also net-next. We might have to have two different patches. Just carrying the revert forward is going to cause some complicated merging and a broken -next. Regards Marcel

Want me to disconnect the device and then reconnect it using bluetootctl? I'll go do that now... Ok, it's attached, I did: $ bluetoothctl disconnect F1:85:91:79:73:70 Attempting to disconnect from F1:85:91:79:73:70 [CHG] Device F1:85:91:79:73:70 ServicesResolved: no Successful disconnected And then the gnome bluetooth daemon (or whatever it has) reconnected it automatically, so you can see the connection happen, and some movements in the log. If there's anything else you need, just let me know. thanks, greg k-h

Now I am confused. What is the content of /sys/kernel/debug/bluetooth/hci0/identity_resolving_keys? The only way I can explain this if you have an entry in that file, but the device is not using it. If you have btmgmt (from bluez.git) you can try "./tools/btmgmt irks” to clear that list and try again. Regards Marcel

Want me to reboot to a "clean" 5.9-rc8? I rebooted into a clean 5.9-rc8 and the device does not connect. So I did the following to trace this: $ sudo btmgmt irks Identity Resolving Keys successfully loaded $ sudo cat /sys/kernel/debug/bluetooth/hci0/identity_resolving_keys $ bluetoothctl connect F1:85:91:79:73:70 Attempting to connect to F1:85:91:79:73:70 Failed to connect: org.bluez.Error.Failed and ran another btmon session to see this, it is attached. thanks, greg k-h

Ok, I remove the entry for IdentityResolvingKey and restarted bluetoothd and now it works on a clean 5.9-rc8! I'll stop it again and run the monitor and attach it below when it starts back up. Ah, I did just that, and it did not connect this time. Attached is the trace.

Restarting bluetoothd a few times, and then it stops working on the 2nd restart. Logging out of GNOME and then back in, it's working again. Ugh. Don't know what to say now, but 5.9-rc8 is working for me. I guess. Watch out for this with users when 5.9 is released if they end up with the same problem. Let me do a jump back to 5.8 and then to 5.9 and see if that changes anything... thanks, greg k-h

This reverts commit 0eee35bdfa3b472cc986ecc6ad76293fdcda59e2 as it breaks all bluetooth connections on my machine. Cc: Marcel Holtmann <marcel@holtmann.org> Cc: Sathish Narsimman <sathish.narasimman@intel.com> Fixes: 0eee35bdfa3b ("Bluetooth: Update resolving list when updating whitelist") Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> --- net/bluetooth/hci_request.c | 41 ++----------------------------------- 1 file changed, 2 insertions(+), 39 deletions(-) This has been bugging me for since 5.9-rc1, when all bluetooth devices stopped working on my desktop system. I finally got the time to do bisection today, and it came down to this patch. Reverting it on top of 5.9-rc7 restored bluetooth devices and now my input devices properly work. As it's almost 5.9-final, any chance this can be merged now to fix the issue?
