Hi,
after upgrading to kernel 5.1.1 (and also 5.1.2) my bluetooth speakers
are unable to auto-reconnect. I can connect them without problems, but
once I turn them off and on again an unending sequence of connections
and disconnections begins:
---- manual connection ok ---------
[bluetooth]# connect E0:D1:E6:07:62:E1
Attempting to connect to E0:D1:E6:07:62:E1
[CHG] Device E0:D1:E6:07:62:E1 Connected: yes

[CHG] Device E0:D1:E6:07:62:E1 Connected: yes
[CHG] Device E0:D1:E6:07:62:E1 Connected: no
I've tested this with a number of kernels:
linux-lts 4.19.43: doesn't work
linux 5.0.13: works
linux 5.1: works
linux 5.1.1: doesn't work
linux 5.1.2: doesn't work
All the above tests were done against bluez 5.50. I've also tested
bluez git master against linux 5.1.2 to no avail.
During failed attempts to auto-reconnect, the debug log shows:
May 17 02:25:27 carlos bluetoothd[8178]:

I'm seeing the exact same behavior, but on a mouse (bt 3.x mouse; I
also have another which seems to be BLE and it still connects fine).
Reverting to 5.0 always works.

Please use btmon to collect the HCI trace and attach it to the problem.

Hi Luiz,
I've attached the output for a single auto-reconnect/disconnect sequence.
Notice this was using the 4.19.44 kernel, which is the LTS one in Arch
Linux. As I've pointed out above, the problem seems like a regression,
since it's happening both in older and latest kernels, but not
in-between them.
Best regards

The problem seems to be here:

L2CAP: Connection Response (0x03) ident 1 len 8

Are you seeing any of the following logs on the journal:

Hi,
The HCI log below seems to indicate an issue with the mouse:

From the above it looks like the mouse is initiating an L2CAP Connection
Request to a non-SDP PSM (17 in this case), which is prohibited by the
spec whenever both sides support Secure Simple Pairing (SSP), and the
kernel is correctly responding with a security block error. So to me the
above looks like misbehavior by the mouse. Could you also post the same
log using a kernel that's working for you?

Slight clarification to my earlier mail:

.. *before encryption is enabled*. As can be seen from the log the connection starts unencrypted and does not get encrypted by the time of the L2CAP Connection Request.

When both devices support SSP, encryption is required for any non-SDP PSM. The kernel enforces this regardless of what kind of options were set for the socket.

Perhaps it could be this one:
https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/net/bluetooth/hci_conn.c?id=d5bb334a8e171b262e48f378bd2096c0ea458265
It looks like the test you mentioned it is just above the check for
enc_key_size, though people mentioned it has been working so could it
be that SSP is not enabled after all?
