[PATCH BlueZ 0/1] Fixes busy loop when disabling

[Dimitris]

Reverts a commit which causes bluetoothd to enter a busy loop if
BT is disabled (eg. rfkill block bluetooth) when one or more
devices are connected.

Steps to reproduce are described in these reports:

Kind regards,

Re: [PATCH BlueZ 1/1] Revert "device: Consider service state on device_is_connected"

[Dimitris]

Hi Paul,

> Please document the reason for the revert.

I've since done a narrower change; instead of the revert I'm only 
factoring out the state check that avoids the busy loop at "rfkill block 
bluetooth" time.

Updated cover letter and patch under the "V2" part of the thread:

https://lore.kernel.org/linux-bluetooth/20240404024521.120349-1-dimitris.on.linux@gmail.com/T/#u

Issue steps to reproduce from e.g. 
https://github.com/bluez/bluez/issues/785 :

- Connect at least one device. Tried this with either one of: Logitech 
MX Master 3, Google Pixel Buds Pro.
- Run rfkill block bluetooth
- bluetoothd takes a whole core, GNOME quick settings and status still 
shows bluetooth as "active". I have to kill -9 the process to get the 
block to really complete.
- Turning off the connected device does not break the loop.

Busy loop stack looks like:

> #0  adapter_remove_connection (adapter=0x55a17e6889d0, device=0x55a17e698d30, bdaddr_type=2 '\002') at src/adapter.c:7476

[PATCH BlueZ 1/1] Refactor btd_device_is_connected

[Dimitris]

Splitting the service state test out of btd_device_is_connected
and using the state-specific test from adapter_remove_connection.

This intends to fix a busy loop that happens when BT is disabled
from userspace with e.g. "rfkill block bluetooth".

Perhaps btd_device_bearer_is_connected would be a better name.

I guess the problem is that some service is indicating it is still
connected though?

Thanks, I'll rename.

Newbie question for sure, but: As this is happening in the code path for 
"disabling bluetooth", shouldn't services already be disconnected here?

That is exactly what I would like to know, why is there a service
still indicating it is connected if the controller is rfkilled, so
while this should break it back to the old behavior we still need to
fix the service that is causing the problem so perhaps we need to
print its profile/drive name and figure out what is the driver that is
causing it.

And it seems that every device I have available triggers this:  MX 
Master 3 mouse, Google Pixel Buds Pro, Google Pixel 7.  Ran experiments 
with each one of the devices being connected when running rfkill block:

The BT adapter is a Mediatek MT7922 WiFi/BT M2 adapter, seems to be 
using the btmtk driver.

In parallel, I've sent a V3 of the "bring back previous behavior" patch 
with the new function named btd_device_bearer_is_connected.

[PATCH BlueZ 0/1] V3: Fix busy loop when disabling BT

[Dimitris]

Splitting the service state test out of btd_device_is_connected
and using only the bearer-specific test from adapter_remove_connection.

This intends to fix a busy loop that happens when BT is disabled
from userspace with e.g. "rfkill block bluetooth":

1. Connect at least one device.
2. Run rfkill block bluetooth.
3. bluetoothd takes 100% CPU.
