Add association between extended advertising, periodic

Error conditions being, trying to create BIG without a valid

vendor-specific content to internal header files, in particular ADV
buffer handling. Define the vendor-specific type lll_adv_pdu in a

Remove LL_ASSERT from functions that return latest advertising PDU.
The LL_ASSERT was raised in situation that there is no memory to
store unused PDUs memory in a pdu_free queue or extra_data_free queue
Those functions return NULL in such sitation. The returned value is
verified by callers by LL_ASSERT. That gives better context if lack
of memory issue issue occurs.

Besides that there was removed a LL_ASSERT from lll_adv_pdu_and_extra_-
data_alloc. The reasons is the same as above, to give better context
when the lack of memory issue occurs.
This function is used in ULL context (ll_adv_sync_ad_data_set).
If it returns NULL the caller will return BT_HCI_ERR_MEM_CAPACITY_-

Add set of functions that will make possible to configure

Some of the new Radio API functions are provided as separate
functions changing the same Radio peripheral registers, e.g.
radio_df_mode_set_aoa, radio_df_mode_set_aod. This is done on
purpose and is related with lack of DFE in nrf52_bsim.
To avoid use of conditionally compiled constants to represent
e.g. CTE mode; separate functions were introduced.
Thanks to that DF unit tests are able to compile successfully
without changes in nrf52_bsim platform. Also if DFE is added
to nrf52_bsim there is no need to change the code until it is

b56a2d1384 Bluetooth: controller: Add extra data storage for ext. adv. configuration
The storage for extra data is required for implementation of
CTE transmission with periodic advertising.

Data required to transmit CTE correctly are compound of two parts:
- PDU field CTEInfo
- radio configuration to transmit actual constant tone at the end
  of PDU.

Extra data is a storage required for radio configuration data.
Nevertheless it must be in compliance with content of CTEInfo field.
Because of that extra data is stored as part of lll_adv_pdu and
is double buffered like PDU memory.

Bluetooth 5.1 spec. allows to enable or disable CTE TX
and change CTE TX parameters when periodic advertising is
enabled. Besides that CTE TX settings may be set before periodic
advertising parameters are set. In such situation ll_adv_sync_set
may be not yet created.
To overcome these constraints ULL should store CTE TX
settings and forward them to LLL only when CTE TX is enabled.
Because of above reasons ULL stores CTE TX settings in ll_adv_set.

10841b9a14 Bluetooth: host: Release ATT request buffers once sent
The ATT request buffers are held until the ATT response has been
received. This means that the ATT request buffers are released by the
RX thread, instead of the from the RX priority context of
num_complete.
This can cause a deadlock in the RX thread when we allocate buffers
and all the available buffers are ATT requests, since the RX thread is
the only thread that can release buffers.

Release the ATT request buffers once they have been sent and instead
handle ATT request resending by reconstructing the buffer from the
GATT parameters.

Also re-order the order of resource allocation by allocating the
request context before the buffer. This ensures that we cannot
allocate more buffers for ATT requests than there are ATT requests.

Fixed a buf reference leak that could occur when the ATT request buffer
has been allocated, but GATT returns an error before handing the
responsebility of the buffer to ATT, for example when bt_att_req_alloc
fails.
This is fixed by moving the functionality of att_req_destroy to
bt_att_req_free.

When ATT resends an ATT request it is sent as a "response" instead of
as a request. This causes the ATT request buffer to be released and
the ATT request cannot be resent one more time.

This causes a problem when the ATT request requires authentication
but the elevation of security is not enforcing MITM protection.
In this case the ATT will first require security level 2 and then resend
the request once this has been reached.
This will lead to a new ATT error response and ATT will require security

dbe4a5f0d2 Bluetooth: host: Remove ATT modification of L2CAP conn pointer
Remove ATT modifying the L2CAP channel state by unassigning the
the connection pointer on timeout.
Unassigning this pointer does not prevent the ATT channel from receiving
since bt_l2cap_recv does not inspect this pointer before calling the
channel receive function.
This prevented the disconnected callback from being called on the
channel after the channel had timed out, but since the disconnected
callback now handles this case this workaroun is no longer needed.

28bddf9380 Bluetooth: host: Handle ATT timeout on disconnected ATT channel
Handle ATT timeout on disconnected ATT channel.
When the ATT channel is disconnected with a pending request the ATT
timeout is canceled and the response processed with an error code.
However canceling of delayed work is not guaranted to succeed, e.g:
"Work queue thread has removed the work item from the queue but has not
 called its handler"
This could lead to timeout handler being invoked after the disconnected
handler.

561a8e4f0e Bluetooth: Mesh: Break up mesh settings
The mesh settings.c module is a giant piece of code responsible for
storing the mesh stack configuration. Such approach makes it difficult
to control the data to be stored, breaks the stack modules'
encapsulation by forcing them to reveal the internal kitchen, which
leads to unpleasant issues such as #19799.

This commit moves the responsibility of storing the configuration
to corresponding modules while keeping control of the moment of storing
the configuration and of starting the stack after the settingss loading
is completed.

This doesn't introduce any abstraction between the mesh settings.c and
other modules as it will add more complexity and overhead than necessary
for the actual task.

Improve multiple DHKey handling by allowing the next DHKey calculation
to be started in the dhkey ready callback.

07ebf3d06d Bluetooth: controller: Release resources on failed AUX_CONNECT_RSP
We allocate nodes on receiving AUX_CONNECT_REQ, but we can only use
them if AUX_CONNECT_RSP is sent successfully. If that fails, we need
to release those nodes.

3fc74be7e7 Bluetooth: controller: Allow to simply release node allocated in LLL
If we allocate a node in LLL and it turns out that we don't need it
(e.g. allocated connection on AUX_CONNECT_REQ, but connection handshake
did not complete and we don't need it) we still need to send it to ULL
to be released. We can use existing NODE_RX_TYPE_DC_PDU_RELEASE node
type for this purpose, but we just need to make sure it's passed from
LLL to ULL properly.

Also, since this now does not only release DC PDUs, let's change its
name to a more generic one.

dd102e61c0 Bluetooth: controller: Add support for connectable ext adv
This adds handling for received AUX_CONNECT_REQ PDU which enables slave
connection with extended advertising.

Once AUX_CONNECT_REQ is received, standard checks are performed to
determine if we have resource to create connection, however unlike for
CONNECT_IND an rx node is temporarily kept in LLL until AUX_CONNECT_RSP
is successfully sent. This is to prevent creating a connection in case
response PDU was not sent for whatever reason.

A separate scratch buffer is created for AUX_CONNECT_RSP since default
radio scratch buffer is already used by received AUX_CONNECT_REQ.

transmitWindowDelay is either 2.5ms or 3.75ms when AUX_CONNECT_REQ is
used (for 1M/2M and Coded respectively). It also uses the same unit
as transmitWindowOffset (1.25ms) so we can just simply add both.

68723274da Bluetooth: controller: Use decoded AdvA/TargetA for conn ind helper
The same helper will be used for legacy and extended advertising so we
better pass AdvA and TargetA directly instead of complete advertising
PDU. This is because those fields are at different locations in legacy
and extended advertising PDUs so caller can figure them out.

Also, we can now check for directed advertising using TargetA since it
will be only supplied for such advertising (NULL otherwise).
