* Setting the adv data, scan rsp and adv aux ad data can happen on
overlapping buffers
* There can be other memcpy's that need to be changed to memmove but
these are the only ones I could reproduce the issue and since memmove
has a performance penalty, I left the others as is.

c334ed515b Bluetooth: Controller: Fix multiple Extended Adv chain reception
Fix assertion when enabling simultaneous multiple Extended
Advertising chain reception that is enabled by increasing
supported auxiliary scan contexts.

ULL sets the association of aux context to scan and sync
context, and LLL resets the association; this is safer
compared to earlier implementation where ULL did both the
association and reset which caused aux context memory
leak.

Supported auxiliary scan contexts can be increased using
CONFIG_BT_CTLR_SCAN_AUX_SET value.

670bd3bed2 Bluetooth: controller: fixing issue re. assert on overlapping conn upd proc
If a connection update (from central) overlaps a peripheral initiated
conneection param request, then central rejects peripheral request
and continues central procedure. This lead to an assert in peripheral
On instant there would not be an rx_node for notification, as this
would have been discarded by the reception of the REJECT.

This fix ensures that once an rx_node has been 'accepted' for retention
it will not be discarded/overwritten by future rx_nodes

The test will trigger the assert without the fix in.

417a9e81ec Bluetooth: Controller: Add device tree dependency to selection
This commit makes the device tree configuration decide
which link layer is compiled in. We do this to avoid
hard-to-understand linker errors referencing device tree nodes.

The following configuration creates a difficult to parse
linker error:
* BT_LL_CHOICE contains multiple entries, BT_LL_SW_SPLIT
  is selected.
* Each BT_LL_CHOICE has its own unique device tree node with its
  own "compatible".
* Only one of the link layer device tree nodes has status "okay",
  but not the one corresponding to BT_LL_SW_SPLIT.

The linker error indicates that code using the HCI driver fails
to link with the controller. This because the HCI driver device
tree node references the link layer selected in devicetree which
is not compiled in.

By adding a dependendency to the device tree node, this can no longer
happen. Instead, if BT_LL_SW_SPLIT is now selected in a configuration
file, a Kconfig warning will be issued:

```
warning: The choice symbol BT_LL_SW_SPLIT
(defined at subsys/bluetooth/controller/Kconfig:129) was
selected (set =y), but BT_LL_SOFTDEVICE (defined at
/home/ruge/ncs/nrf/subsys/bluetooth/controller/Kconfig:11)
ended up as the choice selection.
```

This should be easier to understand than:

```
...(hci_core.c.obj):(.data.bt_dev+0x16c):
undefined reference to `__device_dts_ord_132'
```

After this commit we should consider getting rid of link layer
selection from Kconfig completely as the link layer is in practice
selected through device tree.

Unit tests have been updated to satisfy the dts dependency.

9fa18600ee Bluetooth: Controller: Fix hang due to loop in node_rx list
Fix Controller hang due to infinite looping caused by
duplicate node_rx enqueued in auxiliary context.

When LLL scheduling is not applied due to invalid aux offset
then ULL scheduling too would skip setting up the reception
after similarly checking the validity of aux offset required
to schedule the reception of auxiliary PDU. This check in
ULL was after the received node_rx being enqueued into the
auxiliary context causing a loop in the list of node_rx.

Dequeue of a list with a loop of node_rx caused an infinite
loop execution in the Controller.

Regression introduced in commit 3590bd648f ("Bluetooth:

Only 3 bytes (PDU_EM_LL_SIZE_MAX) is required for empty PDU
transmission, but in case of Radio ISR latency if rx packet
pointer is not setup then Radio DMA will use previously
assigned buffer which can be this empty PDU buffer. Radio
DMA will overrun this buffer and cause memory corruption.
Any detection of ISR latency will not happen if the ISR
function pointer in RAM is corrupted by this overrun.
Increasing ISR latencies in OS and CPU usage in the
ULL_HIGH priority if it is same as LLL priority in
Controller implementation then it is making it tight to
execute Controller code in the tIFS between Tx-Rx PDU's

64faceea72 Bluetooth: controller: Stop Sync ISO ticker when establishment fails
When an ISO stream fails to sync to a broadcaster within the first 6
events, the establishment fails (as expected). However, it did not stop
the ticker, and subsequently it was impossible to establish a new sync
after this.

Make asynchronous call to ticker_stop when establishment fails, and exit
done handling. Cleanup is handled via ll_rx_dequeue().

This fixes a bug where the stack may get stuck in the
POWER_CLOCK ISR after enabling and disabling the Bluetooth
stack a couple of times. It happens after calling
`onoff_request()` after a failing call to `onoff_release()`.
Then the `lf_cli`s next points to itself, generating a
circular list of clients.

Calling `onoff_release()` may fail if there is an outstanding
request. By calling `onoff_cancel()` we enter a state where
we can safely remove the client.

This was not seen earlier because the return value
from `ll_deinit()` in `hci_driver_close()` was ignored.

it to be very complex and awkward to use. In addition, it only handles
a single PDU, meaning callers have to handle the chain.
It has been replaced with simpler, more complete functions for handling
the relevant operations

Fixed issues include:

- Fragmentation of adv data over HCI is now decoupled from PDU
  fragmentation, fixing HCI/DDI/BI-13-C, LL/DDI/ADV/BV-26-C and
  LL/DDI/ADV/BV-55-C
- Adding BigInfo now preserves the PDU chain
- Enabling periodic advertising with ADI on would sometimes fail
  due to insufficient space in a single PDU to add ADI

e9256135d6 Bluetooth: Controller: nrf5: Allocate GPIOTE channels
Allocate the GPIOTE channels that the Bluetooth Controller needs to use
with the dedicated function provided by the nrfx_gpiote driver instead
of using hard-coded indexes of these channels, as now, when the driver
supports multiple GPIOTE instances, it would be much more difficult to
properly inform the driver which channels should be reserved.

06870146e6 Bluetooth: controller: Allow any valid ISO sync receiver BIG handle
The BIG handle for an ISO sync receiver is provided by the host. The
valid range is [0x00..0xEF], and this requires the controller to allow
non-consecutive handle numbering. This means that even if only one sync
set is supported, a BIG handle of ex. value 2 must be supported.

As the code uses indexing and range checking directly by handle, this
needs to be changed. Introducing the handle index, which sequnces the
handles such that index = 0 is always the "first handle", regardless
of value.

slight overhead on the controller side of enabling some more vendor

7f82b6a219 Bluetooth: controller: Prevent invalid compiler code reordering
In ull_disable, it is imperative that the callback is set up before a
second reference counter check, otherwise it may happen that an LLL done
event has already passed when the disable callback and semaphore is
assigned.

This causes the HCI thread to wait until timeout and assert after
ull_ticker_stop_with_mark.

For certain compilers, due to compiler optimizations, it can be seen
from the assembler code that the callback is assigned after the second
reference counter check.

By adding memory barriers, the code correctly reorders code to the
expected sequence.
