commit 72ef98445a upstream.
While looking at a crash report on a timer list being corrupted, which
usually happens when a timer is freed while still active. This is
commonly triggered by code calling del_timer() instead of
del_timer_sync() just before freeing.
One possible culprit is the hci_qca driver, which does exactly that.
Eric mentioned that wake_retrans_timer could be rearmed via the work
queue, so also move the destruction of the work queue before
del_timer_sync().

[ Upstream commit e4412654e2 ]
There is a conflict between MediaTek wmt event and msft vendor extension
logic in the core layer since 145373cb1b ("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.

Fix the following kernel oops in btmtksdio_interrrupt

[ 14.339168] kthread+0x148/0x3ac
[ 14.339176] ret_from_fork+0x10/0x30
That happened because hdev->power_on is already called before
sdio_set_drvdata which btmtksdio_interrupt handler relies on is not
properly set up.
The details are shown as the below: hci_register_dev would run
queue_work(hdev->req_workqueue, &hdev->power_on) as WQ_HIGHPRI
workqueue_struct to complete the power-on sequeunce and thus hci_power_on
may run before sdio_set_drvdata is done in btmtksdio_probe.
The hci_dev_do_open in hci_power_on would initialize the device and enable
the interrupt and thus it is possible that btmtksdio_interrupt is being
called right before sdio_set_drvdata is filled out.
When btmtksdio_interrupt is being called and sdio_set_drvdata is not filled
, the kernel oops is going to happen because btmtksdio_interrupt access an
uninitialized pointer.

Currently, there is a loop in btmtksdio_txrx_work() which iteratively

But the variable int_status should be masked out with the actual interrupt
sources (MTK_REG_CHISR bit 0-15) before we check the loop condition.
Otherwise, RX_PKT_LEN (MTK_REG_CHISR bit 16-31) which is read-only and

commit b3cf94c8b6 upstream.
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).

This patch fixes the broken LED quirk for Intel legacy ROM devices.
To fix the LED issue that doesn't turn off immediately, the host sends
the SW RFKILL command while shutting down the interface and it puts the
devices in SW RFKILL state.
Once the device is in SW RFKILL state, it can only accept HCI_Reset to
exit from the SW RFKILL state. This patch checks the quirk for broken
LED and sends the HCI_Reset before sending the HCI_Intel_Read_Version
command.

sock.h is pretty heavily used (5k objects rebuilt on x86 after
it's touched). We can drop the include of filter.h from it and
add a forward declaration of struct sk_filter instead.
This decreases the number of rebuilt objects when bpf.h
is touched from ~5k to ~1k.
There's a lot of missing includes this was masking. Primarily
in networking tho, this time.

For Mediatek chipset, it can not enabled if there are something wrong
in btmtk_setup_firmware_79xx(). Thus, the process must be terminated
and returned error code.

This makes btusb to queue ACL and events during a polling interval
by using of a delayed work, with the interval working as a time window
where frames received from different endpoints are considered to be
arrived at same time and then attempt to resolve potential conflics by
processing the events ahead of ACL packets.
It worth noting though that priorizing events over ACL data may result
in inverting the order compared to how they appeared over the air, for
instance there may be packets received before a disconnect event that
will be discarded and unencrypted packets received before encryption
change which would considered encrypted, because of these potential
changes on the order the support for queuing during the polling
interval is not enabled by default so it requires setting
force_poll_sync debugfs while the adapter is down.

Some Macs with the T2 security chip had Bluetooth not working.
To fix it we add DMI based quirks to disable querying of LE Tx power.

btmtksdio have to rely on MMC_PM_KEEP_POWER in pm_flags to avoid that
SDIO power is being shut off during the device is in suspend. That fixes
the SDIO command fails to access the bus after the device is resumed.

Runtime pm ops is not aware the sdio_func status that is probably
being disabled by btmtksdio_close. Thus, we are only able to access the
sdio_func for the runtime pm operations only when the sdio_func is
available.

Cancel sync commands when transmission of URBs fail. This is done for
both failures to send a command URB and also when the interrupt URB used
to retrieve a response fails.
This approach is sufficient to quickly deal with certain errors such as
a device being disconnected while synchronous commands are done during
initialization.

After the previous patches, noone needs 'file' parameter in neither
ioctl hook from tty_ldisc_ops. So remove 'file' from both of them.

The board ID should be split into two bytes.
The 1st byte is chip ID, and the 2nd byte is platform ID.
For example, board ID 0x010A, 0x01 is platform ID. 0x0A is chip ID.
we have several platforms, and platform IDs are continuously added.
We would not distinguish different chips if we get these mixed up.
Platform ID:
0x00 is for Mobile
0x01 is for X86
0x02 is for Automotive
0x03 is for Consumer electronic
