Bluetooth: btusb: Use quirk to skip HCI_FLT_CLEAR_ALL on fake CSR controllers

2022-03-18T16:12:07+00:00

Another subset of the more recent batch of Chinese clones aren't
specs-compliant and seem to lock up whenever they receive a
HCI_OP_SET_EVENT_FLT with flt_type set to zero/HCI_FLT_CLEAR_ALL,
which on Linux (until the recent HCI state-machine refactor) happened
right at BR/EDR setup. As there are other less-straightforward ways
of reaching those operations, this patch is still relevant.

So, while all the previous efforts to wrangle the herd of fake CSRs
seem to be paying off (and these also get detected as such) we
still need to take care of this quirk; testers seem to agree
that these dongles tend to work well enough afterwards.

From some cursory USB packet capture on Windows it seems like
that driver doesn't appear to use this clear-all functionality at all.

This patch was tested on some really popular AliExpress-style
dongles, in my case marked as "V5.0". Chip markings: UG8413,
the backside of the PCB says "USB Dangel" (sic).

Here is the `hciconfig -a` output; for completeness:

Also, changed the benign dmesg print that shows up whenever the
generic force-suspend fails from bt_dev_err to bt_dev_warn;
it's okay and done on a best-effort basis, not a problem
if that does not work.

Also, swapped the HCI subver and LMP subver numbers for the Barrot
in the comment, which I copied wrong the last time around.

Bluetooth: mediatek: fix the conflict between mtk and msft vendor event

2022-03-04T15:10:50+00:00

There is a conflict between MediaTek wmt event and msft vendor extension
logic in the core layer since 145373cb1b1f ("Bluetooth: Add framework for
Microsoft vendor extension") was introduced because we changed the type of
mediatek wmt event to the type of msft vendor event in the driver.

But the purpose we reported mediatek event to the core layer is for the
diagnostic purpose with that we are able to see the full packet trace via
monitoring socket with btmon. Thus, it is harmless we keep the original
type of mediatek vendor event here to avoid breaking the msft extension
function especially they can be supported by Mediatek chipset like MT7921
, MT7922 devices and future devices.
