[PATCH 0/1] Fix MSFT filter enable

[PATCH 0/1] Fix MSFT filter enable

[Brian Gix]

This patch recodes the execution of msft_set_filter_enable() to use the
syncronous HCI cmd opcode method (__hci_smd_sync_status()). This
function is called from within a safe, blockable context that also calls
the syncronous read_supported_features() call.

I have tested this to my satisfaction, but would like a testing pass be
made by @Mateusz (mat.jonczyk@o2.pl) if possible.

[PATCH 1/1] Bluetooth: Convert MSFT filter HCI cmd to hci_sync

[Brian Gix]

The msft_set_filter_enable() command was using the deprecated
hci_request mechanism rather than hci_sync. This caused the warning error:
hci0: HCI_REQ-0xfcf0

Hello,

On the first time I was testing this patch, I was heavily testing
various Bluetooth functionality. Eventually, something stopped working
and I was no longer able to establish a Bluetooth connection between
my mobile phone and my laptop. To try to resolve this issue, I tried suspending
my laptop, but after resume, I got a kernel panic (dmesg attached below, I may
provide journal extracts on request).

Unfortunately, I am unable to reproduce this issue. Just before this,
I was trying to stream music from my laptop to mobile phone by Bluetooth.
I was trying various knobs and options, but without installing proprietary codecs.
I do not use Bluetooth audio normally.

Rough testing notes:

1. Sending an image file to mobile phone - OK.
2. Sending an image file from mobile phone to laptop - failed somehow,
    turning Bluetooth on and off on mobile phone helped.
3. Bluetooth network tethering from mobile phone - OK.
4. Sending an image file from mobile phone to laptop - worked
    (though slow, but it has always been this way).
5. Sending audio from my laptop to mobile phone - failed
    (probably because I did not install proprietary media codecs).

Today, I have successfully configured a BLE server on my laptop roughly using this guide:
https://punchthrough.com/creating-a-ble-peripheral-with-bluez/
and verified it with the "BLE Scanner (Connect & Notify)" tool from Google Play
(the BLE apps from F-Droid I have tried have limited functionality).
This is (from what I understand) the functionality this patch touches.

Today, sending / receiving image files from / to mobile phone works correctly,
but is slow as always (roughly ~100kB/s).

I don't see the following messages in dmesg any more:
      hci0: HCI_REQ-0xfcf0
but I see the following ones:
      Bluetooth: hci0: HCI_REQ-0x0401
which are triggered by "hcitool scan".

I'm also seeing things like this in "dmesg --level err":

[ 4627.435040] Bluetooth: hci0: Opcode 0x 401 failed: -16
[ 4633.217405] Bluetooth: hci0: HCI_REQ-0x0401
[ 4637.336968] Bluetooth: hci0: Opcode 0x 401 failed: -16

This will not happen during normal operation...  The hcitool opens an
HCI_USER socket, which bypasses all of the kernel based MGMT control,
and gives the user space tool direct control over the controller, and
taking it offline for any shared usage. It therefore does not have the
race conditions that were inherent in MGMT when used by multiple user
threads.   We therefore left the hci_request mechanism in place (in
hci_core.c) to issue the HCI commands from the hcitool.

Hello,

I have to apologize for the delay.

This kernel panic happened to me again, without this patch so now I can
say that it is unrelated. I have again tested the patch you provided and
Bluetooth with it appeared to be working correctly. I have even tested
with a mobile app called "Beacon Simulator" [1] and the beacon was
successfully found on my laptop.

I have tested this on top of 6.2.0-rc8.

Additionally, to see how it worked, I tested it with some debugging
printks and additional calls to
	msft_set_filter_enable(hdev, X);
(patch attached below) and the code appears to do as it is intended, but
when I combined two 
	msft_set_filter_enable(hdev, true);
calls one after the other, I got something like this:

	Bluetooth: hci0: BEGIN msft_set_filter_enable(hdev, 1)
	Bluetooth: hci0: BEGIN msft_le_set_advertisement_filter_enable_cb(hdev, user_data, 0)
	Bluetooth: hci0: END msft_set_filter_enable(hdev, 1), err = 0
	Bluetooth: hci0: BEGIN msft_set_filter_enable(hdev, 1)
	Bluetooth: hci0: Opcode 0xfcf0 failed: -16
	Bluetooth: hci0: BEGIN msft_le_set_advertisement_filter_enable_cb(hdev, user_data, f0)
	Bluetooth: hci0: END msft_set_filter_enable(hdev, 1), err = -16

instead of the error code 0x0C as is described in a comment in
msft_le_set_advertisement_filter_enable_cb() and the Microsoft
specification. Is this expected?

In msft_set_filter_enable() your patch also casts err from int to u8
while calling msft_le_set_advertisement_filter_enable_cb() without
checking its sign.

Greetings,

Mateusz

[Gix, Brian]

Hi Luiz,

Do you need the original patch re-generated, or can you find it in this
thread?
