d93489035c Bluetooth: host: Add flag to indicate ext adv set
It should be possible to identify whether advertising set uses legacy
or extended advertising to avoid performing operations that are not
supported on either of them.

For example, scannable advertising can have advertising data set only
if legacy PDUs are used.

Add support for multiple advertising set. Move the advertising state
flags to be per advertising set and loop over advertising sets instead
of looking up legacy advertiser set or handle 0.

Since it is not certain that the advertising set terminated event can
arrive directly after the connection complete event there is currently
a limitation that there can only be one local identity used by
connectable advertisers at a time. This guarantees that we know
the local identity being used in the connection complete event.

18bee9178f Bluetooth: host: Add non-connectable directed advertising support
This patch introduces two major changes to the directed advertising
feature of the bluetooth host.

Deprecating the bt_conn_create_slave_le, and removing
bt_conn_le_create_slave which has never been released. This behaviour
has now been moved by to providing the peer direct address into the
advertising parameters.

Introducing directed advertising support for nonconnectable
directed extended advertising, both scannable and non-scannable.

A bug was also fixed in the the directed-adv command in the shell
when the argument "low" was given. The advertiseng parameter pointer
declared with BT_LE_ADV_CONN_DIR_LOW_DUTY was declared in a scope that
was no longer valid when it was used to start the advertiser.

19434a1056 Bluetooth: host: Do not set adv random address before adv parameters
The LE Set Extended Advertising Set Random Address command may be
issued at any time after an advertising set identified by
the Advertising Handle parameter has been created using the
LE Set Extended Advertising Parameters command.

This commit fixes the advertising set issueing the set random address
command before the advertising set is created in the controller.
Since the le_adv_set_random_addr function has is used to get the the
own address parameter for the it could not simply be moved, and
moving the own address parameter handling out of this function
would create a potentioal maintaince problem.
Also this function is used for both with and without advertising
extension feature so changing it is not trivial without breaking all
the previous random address handling already put in place.
The simplest solution was therefore to postpone the command until the
parameters has been set using 2 flags.

   for this identity would be randomly generated but not

2. Fix the handling of the above issue which was fixed
   for the random address but would initiate settings save

3. Fix the host not using the Vendor Specific HCI commands

   to generate an IRK as specified in the BT Core spec.

d8689cdc72 Bluetooth: host: Fix deadlocks with pending TX packet handling
This is a moderate redesign of the pending TX packet handling that
aims to eliminate potential deadlocks between the TX thread and the
system workqueue thread. The main changes are:

 - TX context (bt_conn_tx) is allocated during buffer allocation, i.e.
   not in the TX thread.

 - We don't allocate a TX context unless there's an associated
   callback. When there's no callback simple integer counters are used
   for tracking.

 - The TX thread is no longer responsible for TX callbacks or
   scheduling of TX callbacks. Instead, the callbacks get directly
   scheduled (k_work_submit) from the RX priority thread.

 - CONFIG_BT_CONN_TX_MAX defaults to CONFIG_BT_L2CAP_TX_BUF_COUNT,
   and in most cases wont need changing. The value now only indicates
   how many pending packets with a callback are possible.

0bf9931c2c Bluetooth: Host: Fix create connection fails to stop scanner
Fix race condition in bt_conn_create_le for the state of the scanner in
the Host. This leads to the host issuing a create connection command
without stopping the scanner first. This leads to command disallowed and
failing to establish connection. As well as inconsistent state in the
host which does not allow to stop the running scanner.

The race condition exists because the processing of le_adv_report
handler is done before the thread that called bt_conn_create_le was
woken up to continue after the command_complete event.

12a413779d Bluetooth: Fix init procedure handling with BT_SETTINGS
The treatment of the BT_DEV_READY flag was broken when used together
with BT_SETTINGS. The flag would get set even though the stack was
still in a partially initialized state. Even worse, for central role
the stack would potentially try to initiate passive scanning without

Refactor the code that sets the BT_DEV_READY flag (among other
initialization) into a separate bt_finalize_init() helper function and
call it when the settings have been loaded. Also clarify the warning
message given to the user in case settings_load() needs to be called.

d22b7c9f2d Bluetooth: Remove bt_storage API
The same functionality is now supported by the settings-based
solution, so remove bt_storage out of the way. There were stubs in
bt_storage to handle per-peer information (e.g. pairing keys) but this
was never actually implemented in full. The next step is to add this
support to the settings-based solution.

Leave the code for generating temporary IRK and identity address in
case BT_SETTINGS is not enabled. Also leave the code for using vendor
HCI to read the identity address, in which case the settings
implementation will not touch it.

Introduce a new bt_unpair() API to replace the removed
bt_storage_clear(), since the latter was actually doing more than just
storage management: it was also handling runtime storage of pairing
information. Later, the bt_unpair() implementation will be extended to
clear settings-based pairing storage.

There is one feature that the bt shell module looses: the ability to
give a specific identity address to the "init" command as a parameter.
We might look later in the future if this is really needed, and add a
separate API for this.
