            Bug ID: 203643
           Summary: [REGRESSION][BISECTED] Sixaxis gamepad no longer
                    connects via Bluetooth
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.14.119, 4.19.42, 5.0.16, 5.1.3
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Bluetooth
          Assignee: [email protected]
          Reporter: [email protected]
        Regression: No

Hi,

Since commit d5bb334a8e171b262e48f378bd2096c0ea458265 some devices doesn't connect via bluetooth (like Sixaxis gamepad). 'bluetoothctl' shows that device is connected, and soon after disconnected.

Link for commit which causes the issue:
https://github.com/torvalds/linux/commit/d5bb334a8e171b262e48f378bd2096c0ea458265

I checked the "conn->enc_key_size", it reports the value of 0 for Sixaxis gamepad (not the value of 7, which is the minimum encryption key size).

I noticed that other people also having issue after kernel upgrade, but I'm not sure if it exactly the same bug:

I confirm the bug related to this commit, and to its backported version in 5.0.15. My device is a Sony DR-BT21G headset.

With this commit, the hcidump reports this error message:

Without it, the hcidump reports a successful connection:

Just chiming in to report that this bug also affects HHKB-BT Pro (Happy Hacking BT Keyboard).

It happens regardless of which BT controllor/adaptor that I use. I haven't yet had the chance to attempt backing out the change conditional that could be causing the issue in 5.0.16, but will try to find time in the next week or so.

With the breadth of devices that are affected, I imagine this should be fixed quickly.

For my Logitech BT 2.0 mouse, this bug is fixed by Fedora kernel 5.1.4.

For reference to others Fedora pulled in the RFC patch to the Fedora 5.1.4 build.

Sadly the RFC patch above does not fix it for me, the revert does The device is edifier w330nb headset.

It also did not fix it for my two Sony DualShock 4 Wave Blue CUH-ZCT1 (the issue was reproducible with both), although it did for the following devices:
* Sony DualShock 4 Glacier White CUH-ZCT1 (same generation as the Wave Blue ones);
* Microsoft Bluetooth Mobile Keyboard 6000;
* Memteq Bluetooth Optical Mouse.

The only way to solve the issue for my two DualShock 4 Wave Blue was to revert the culprit commit, just like it has been done recently ->
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.1.10&id=b528880e8b0167c34cb36c1b4e6165192f76267c

Just to confirm that patch does not work for all devices.

This also affects the PS3 Blu-Ray Remote control, which I use for my media server. After many hours of debugging I came across this regression.

Any news on when the fix (revert commit d5bb334a8e171b262e48f378bd2096c0ea458265) will reach upstream?

--- Comment #22 from Matias Karhumaa ([email protected]) --- Hi Martin,

There is another regression: https://bugzilla.kernel.org/show_bug.cgi?id=203997

If the remote control has minimum enc key size of 7, then this is most likely same problem. Could you check with btmon?

Feel free to try the patch posted on mailing list.

Br,
Matias
