For advertising, we wish to know the LE tx power capabilities of the
controller in userspace, so this patch edits the Security Info MGMT
command to be more generic, such that other various controller
capabilities can be included in the EIR data. This change also includes
the LE min and max tx power into this newly-named command.
The change was tested by manually verifying that the MGMT command
returns the tx power range as expected in userspace.

Queries tx power via HCI_LE_Read_Transmit_Power command when the hci
device is initialized, and stores resulting min/max LE power in hdev
struct. If command isn't available (< BT5 support), min/max values
both default to HCI_TX_POWER_INVALID.
This patch is manually verified by ensuring BT5 devices correctly query
and receive controller tx power range.

This patch takes the min/max intervals and tx power optionally provided
in mgmt interface, stores them in the advertisement struct, and uses
them when configuring the hci requests. While tx power is not used if
extended advertising is unavailable, software rotation will use the min
and max advertising intervals specified by the client.
This change is validated manually by ensuring the min/max intervals are
propagated to the controller on both hatch (extended advertising) and
kukui (no extended advertising) chromebooks, and that tx power is
propagated correctly on hatch. These tests are performed with multiple
advertisements simultaneously.

This patch adds support for the new advertising add interface, with the
first command setting advertising parameters and the second to set
advertising data. The set parameters command allows the caller to leave
some fields "unset", with a params bitfield defining which params were
purposefully set. Unset parameters will be given defaults when calling
hci_add_adv_instance. The data passed to the param mgmt command is
allowed to be flexible, so in the future if bluetoothd passes a larger
structure with new params, the mgmt command will ignore the unknown
members at the end.
This change has been validated on both hatch (extended advertising) and
kukui (no extended advertising) chromebooks running bluetoothd that
support this new interface. I ran the following manual tests:
- Set several (3) advertisements using modified test_advertisement.py
- For each, validate correct data and parameters in btmon trace
- Verified both for software rotation and extended adv
Automatic test suite also run, testing many (25) scenarios of single and
multi-advertising for data/parameter correctness.

This patch implements the interleaving between allowlist scan and
no-filter scan. It'll be used to save power when at least one monitor is
registered and at least one pending connection or one device to be
scanned for.
The durations of the allowlist scan and the no-filter scan are
controlled by MGMT command: Set Default System Configuration. The
default values are set randomly for now.

Emit controller suspend and resume events when we are ready for suspend
and we've resumed from suspend.
The controller suspend event will report whatever suspend state was
successfully entered. The controller resume event will check the first
HCI event that was received after we finished preparing for suspend and,
if it was a connection event, store the address of the peer that caused
the event. If it was not a connection event, we mark the wake reason as
an unexpected event.
Here is a sample btmon trace with these events:
@ MGMT Event: Controller Suspended (0x002d) plen 1
Suspend state: Page scanning and/or passive scanning (2)
@ MGMT Event: Controller Resumed (0x002e) plen 8
Wake reason: Remote wake due to peer device connection (2)

For new advertising features, it will be important for userspace to
know the capabilities of the controller and kernel. If the controller
and kernel support extended advertising, we include flags indicating
hardware offloading support and support for setting tx power of adv
instances.
In the future, vendor-specific commands may allow the setting of tx
power in advertising instances, but for now this feature is only
marked available if extended advertising is supported.
This change is manually verified in userspace by ensuring the
advertising manager's supported_flags field is updated with new flags on
hatch chromebook (ext advertising supported).

For some reason they tend to squat on the very first CSR/
Cambridge Silicon Radio VID/PID instead of paying fees.
This is an extremely common problem; the issue goes as back as 2013
and these devices are only getting more popular, even rebranded by
reputable vendors and sold by retailers everywhere.
So, at this point in time there are hundreds of modern dongles reusing
the ID of what originally was an early Bluetooth 1.1 controller.
Linux is the only place where they don't work due to spotty checks
in our detection code. It only covered a minimum subset.
So what's the big idea? Take advantage of the fact that all CSR
chips report the same internal version as both the LMP sub-version and
HCI revision number. It always matches, couple that with the manufacturer
code, that rarely lies, and we now have a good idea of who is who.
Additionally, by compiling a list of user-reported HCI/lsusb dumps, and
searching around for legit CSR dongles in similar product ranges we can
find what CSR BlueCore firmware supported which Bluetooth versions.
That way we can narrow down ranges of fakes for each of them.
e.g. Real CSR dongles with LMP subversion 0x73 are old enough that
support BT 1.1 only; so it's a dead giveaway when some
third-party BT 4.0 dongle reuses it.
So, to sum things up; there are multiple classes of fake controllers
reusing the same 0A12:0001 VID/PID. This has been broken for a while.

Starting with the upgrade to v5.8-rc3, I've noticed I wasn't able to
connect to my Bluetooth headset properly anymore. While connecting to
the device would eventually succeed, bluetoothd seemed to be confused
about the current connection state where the state was flapping hence
and forth. Bisecting this issue led to commit 3ca44c16b0dc (Bluetooth:
Consolidate encryption handling in hci_encrypt_cfm, 2020-05-19), which
refactored `hci_encrypt_cfm` to also handle updating the connection
state.
The commit in question changed the code to call `hci_connect_cfm` inside
`hci_encrypt_cfm` and to change the connection state. But with the
conversion, we now only update the connection state if a status was set
already. In fact, the reverse should be true: the status should be
updated if no status is yet set. So let's fix the isuse by reversing the
condition.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

Let drivers have a hook to disable configuring scanning during suspend.
Drivers should use the device_may_wakeup function call to determine
whether hci should be configured for wakeup.
For example, an implementation for btusb may look like the following:
bool btusb_prevent_wake(struct hci_dev *hdev)
{
struct btusb_data *data = hci_get_drvdata(hdev);
return !device_may_wakeup(&data->udev->dev);

The BT qualification test SM/MAS/PKE/BV-01-C needs us to turn off
the MITM flag when pairing, and at the same time also set the io
capability to something other than no input no output.
Currently the MITM flag is only unset when the io capability is set
to no input no output, therefore the test cannot be executed.
This patch introduces a debugfs option to force MITM flag to be
turned off.
