Update ticker implementation to reschedule unreserved ticker
that use ticks_slot_window.
This will avoid unreserved ticker from continuously
overlapping with reserved tickers. And the change is
required to reduce processing overheads before reserve
ticker timeout callback executes.
Unreserved tickers with ticks_slot_window will always yield
to any colliding reserved or unreserved tickers.
The implementation moves unreserved tickers (no ticks_slot
value, in this case continuous scan window) to end of a
colliding reserved/unreserved ticker so that reserved
tickers (like central role) do not have high overheads due
to unreserved ticker's prepare (scanner) be preempted
everytime before reserved ticker's prepare (central).

Updated the 3 places in extended advertising where the ticker was
previously inquired about the expiration of another ticker ID in a
separate mayfly (adv_aux, adv_sync and adv_iso). It will now use the
new ticker feature where another ticker IDs expiration info will be
added to the callback.
Channel map updates are now handled in ticker_cb and applied immediately
if the ticker is not running

It is now possible (via the extended ticker interface) to ask for
expiration information for another ticker ID to be returned in the
ticker callback. This utilises the extended ticker interface and a

In general, RTC and TIMER driver implements counter API but there
are exception when those peripherals are used in a custom way
(e.g. for system timer or bluetooth). In that case, system must
prevent using counter based on a reserved instance. Previously,
it was managed by Kconfig options but that cannot be maintained
when switching to devicetree configuration of the counter driver.
A new approach removes Kconfig options and instead adds static
asserts in the files which are using direct peripherals. Those
asserts check if given node is not enabled in the device tree.

Fix ull_prepare_dequeue to not skip events when preempt
does not match the event in the head of the prepare queue.
The head of the prepare queue does not match when
ull_prepare_dequeue has put the head of the queue to the
last of the queue when it is calling lll_resume interface.
This happens when there is already an active event which
needs a preempt timeout to be setup and there is another
non-resume event in the pipeline which now becomes the
head. The fix ensure to restore the order of the events
if a preempt timeout was to be setup.
Currently ull_prepare_dequeue loops through all events
before stopping at the original way the queue was. This is
not efficient and is a scope for improvement in future.

The nRF HW models have been updated to correspond to a 52833 instead
of a 52832. Let's follow them.
The motivation for the change is to enable proper BIS encryption support
(for BT LE Audio ISO).
Changes:
* Point in manifest to latest HW models
* SOC_COMPATIBLE_NRF52832 has been removed, and SOC_COMPATIBLE_NRF52833
added in its place (with no uses at this point)
* Where SOC_COMPATIBLE_NRF52832 was used to set encryption like for a 52832
(to avoid using the MAXPACKETLENGHT), we set the condition to just

New LLCP will process the CIS establishement in the TX path, meaning it
will only process once every ACL connection interval.
If ACL connection interval is significantly longer than the ISO
interval, CIS packets corresponding to the ACL connection interval will
be lost. This may cause latency in audio rendition.
By processing the CIS establishment in the RX path, notification will be
sent immediately, and audio path is enabled fast to reduce latency.
When a CIS fails to establish, the controller shall complete the
procedure by sending a CIS_ESTABLISHED event containing the error.

According to Bluetooth 5.3 Vol 4, Part E section 7.7.65.21 the
Controller should send an IQ report with Packet_Status set to 0xFF
and Sample_Count to 0x0, to inform Host that it is not able to
store IQ samples for all received Constant Tone Extensions and has
failed to sample at least once.
This commit adds handling of such situation for direction finding
in connectionless mode in lower link layer. It includes:
- lack of node_rx_iq_report to store IQ samples,
- lack of free node_rx to report received advertising data (generates
an advertising data report with indication "incomplete, no more to
come" and cancels reception of chained PDUs,
- cancellation of chained PDUs reception due to other scheduling
reasons.
In all of these situations CTE reception must be enabled and number of
received CTEs is smaller than requested by Host.
If there is not sufficient number of node_rx_iq_report nodes and
report was generated, the CTE will not be samples in a given
periodic advertising synchronization event. The CTE will be
sampled again in next event if there are node_rx_iq_report available.
End user applications may check periodic advertising sync event
counter when use of the reports to be sure about sync event
the received report is connected with.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

When directed advertising and continuous scanning are
simultaneously active, and a connection request is received
by the directed advertising state then the connection was
not established due to the done event not being generated.
Done event from the directed advertising state was not
generated because the prepare pipeline only had resume
event which does not get scheduled when there is prepare
event of the continuous scan state.
The fix is to explicitly abort all pending prepare and

state when connection request is received.

Nordic Radio Direction Finding Extension provides 12 bits wide IQ
samples. The Bluetooth Core Specification 5.3 Vol 4, Part E sections
7.7.65.21 and 7.7.65.22 limits IQ samples to be 8 bits wide.
There are other way to convert 12 bits IQ samples into Bluetooth Core
specification compliant 8 bits IQ samples than ordinary 4 bits right
shift. If one is sure that samples will never go over 10 bits or 8
bits then, it is allowed to use 2 bits right shift or even 8 least

The initialisation of DLE parameters for the peripheral
was done before the intialisation of the PHY settings.
Since the DLE parameters depend on PHY settings this
can result in incorrect parameters for tx/rx time and
octets
One scenario is where a previous connection set the PHY to
2M or CODED, then when a new connection is established
it uses the same memory-locations for connection settings as the
previous connection, and the (uninitialised) PHY settings will be
set to 2M or CODED, and thus the DLE parameters will be wrong

Mayfly by design uses a memq for storage of its jobs. The memq
requires head and tail to track the content. It is considered
empty is head equals tail.
When memq instance is initialized then there is a new link
instance stored in head and tail, nevertheless the memq is
still empty.
When new job is enqueued to a memq, the inilial link is used
to store the job. New link, provided by enqueue call, is stored
in the tail for future enqueue.
When enqueued job was served and is dequeued, the link it was
assigned to is returned and stored in the job object.
That link will be used in future for call to enqueue.
Now lets consider a situation when we are just after initalization.
Some default initial link is in empty memq. We enqueue and dequeue
a job. After dequeue, the job object stores the initial link object.
The one that was put into the memq during initialization.
Next Bluetooth stack is disabled and enabled again.
The job is enqueued again, but it still stores the initial link
address. After enqueue the memq head points to initial link object,
that stores new job. Tail points to link deliveded by enqueue call,
that is also the initial link object. The memq is considered to be
empty, nevertheless there was a successful enqueue operation.
The issue is casued by lack of re-initialization of a job object
on init. In most cases these objects are static members of some
functions, hence there is no re-initialization after bt_disable
and bt_enable calls.
The problem is fixed by re-initialization of mayfly only once
on bt_enable() call. Then it doesn't matter what links are stored
in dequeued objects and there is no need to re-initialized mayfly
job objects.

If there is a PHY change on a connection it may happen that effective
RX and TX time changes also. That change is applied after an instant.
Implemented handling of effective time calculation is based on the
maximum PDU length, new PHY and local (default) maximum TX or RX time.
The maximum TX value is set to default one that corresponds to PHY 1M
during the Controller initialization. It can be updated by host to other
value. By default Zephyr Host updates it to max possible TX time for all
supported PHYs. If PHY CODED is enabled, it is the longest possible TX
duration 17040 us.
The maximum RX value is set to default during connection creation.
In case of use of legacy advertising, the value is also related with
PHY 1M. It can be updated by data length extension procedure.
If the maximum RX value is set to some value and there is a change
of a PHY to one that requires more time to send a PDU with the same
length, then the maximum RX value is wrongly calculated.
Function pu_calc_eff_time returns a value that is the default_time
argument. The problem is that the default_time should be adjusted
to new maximum RX time required for a new PHY.
To solve that there should be an evaluation of a new maximum RX and
TX time based on new PHY.
The commit adds missing evaluation.
The problem occurred in DF tests that check collision mitigation
between PHY update control procedure and CTE request control procedure.
There was missing CONFIG_BT_CTLR_PHY_CODED option in CTE request
unit tests. The code was working because the ULL implementation of
PHY change control procedure does not verify if PHY CODED is supported.
When missing support was enabled, tests showed wrong evaluation of
maximum RX time. It also unveiled error in CTE request unit tests
implementation. The default_tx_time was set to wrong value 2120 us
as if PHY CODED was not supported. To fix it, the value was changed
to PDU_DC_PAYLOAD_TIME_MAX_CODED.
There was also added a mock for a feature exchange procedure done
during unit tests setup step. That allows to correctly calculate
maximum TX time by ull_dle_max_time_get function.

In case there are pending two control procedures: local and remote,

considered as expected packet for all local and remote control

That is not correct. It does not allow local procedure to handle

A remote device should not send LL_REJECT_IND PDU for locally initiated
control procedures, hence local device should not expect to receive
LL_REJECT_IND PDU to be expected one for pending remote control
procedure.

The CTE request procedure should be enabled only if a peer supports
CTE response feature. That information can be obtained by feature
exchange procedure. If there were no feature exchange then CTE
request feature may be disabled if a peer responses with LL_UNKNOWN_RSP
for a CTE request.
The implementation of ll_df_set_conn_cte_req_enable was checking if
CTE response feature is supported only when there was feature exchange.
There was missing possibility to stop CTE request if a peer responded
with LL_UNKNOWN_RSP for an earlier CTE request.
The commit changes the implementation of ll_df_set_conn_cte_req_enable.
The CTE response feature check is moved to ull_cp_cte_req function,
because it belongs more to control procedure than to function that
handles Host request to start the procedure.
Second change is related with use of conn->llcp.fex.features_used.
It stores information about features supported by peer. It does
not depend on execution of the feature exchange control procedure.

Current implementation of ll_sync_create_cancel does not allow to stop
synchronization after ull_sync_setup is called. When that is done,
sync->timeout_reload is not zero and the ll_sync_create_cancel will
return BT_HCI_ERR_CMD_DISALLOWED. That means the Controller is able to
cancel periodic advertising synchronization only in period between
call to ll_sync_create and reception of AUX_ADV_IND that has SyncInfo
field.
The Controller should be able to cancell synchronization until first
AUX_SYNC_IND PDU is received and host notified about synchronization
established.
Complete information about synchronization status is provdied by two
ll_sync_set members: node_rx_sync_established and timeout_reload.
These two members of the structure were used in ll_sync_create_cancel
function to do a proper cancel and cleanup.
The node_rx_sync_established member was not cleared when sync was
established or expired. That was required to get a proper information
about synchronization state.
Besides that, to avoid race condition between ll_sync_create_cancel
and ull_sync_established_report, the latter function was extended
to check if cancel operation or sync lost has happened.

Direction finding functionality does antenna switching during CTE
reception in AoA mode and CTE transmission in AoD mode. Antennas are
switched according to user provided antenna switch pattern. If a CTE
length is enough to exhaust all antenna ids in a switch pattern then
radio should loopback to reference antenna and continue from switching
from that. Current implementation loops back to antenna that is just
after reference antenna in the switch pattern.
The commit fixes that by insertion of the reference antenna
at the end of switch pattern. Radio will operate as it was before,
it will restart switching from the same index in a switch pattern.
At the same time reference antenna will be inserted into the loop
if switching pattern is exhausted. That also means, the maximum
number of antenna ids in a switch pattern has to be decreased by
one.
The commit also fixes lower bound in the BT_CTLR_DF_MAX_ANT_SW_PATTERN-
_LEN that should be equal two. It was set to three, because in the
past the antenna at index zero was used for reception of a PDU.
Now this antenna ID is provided by device tree configuration.

The SYNC_STAT_READY_OR_CONT_SCAN state into two: SYNC_STAT_READY
and SYNC_STAT_CONT_SCAN. The connected state was used for two
cases:
- synchronization with periodic advertising is already established,
- CTE type is wrong but periodic advertising list is used to filter
synchronized devices.
In the past states were connected because there was only one difference
between them. In case of sync already established, Controller generated
sync report notification to host.The sync was not terminated when
Controller was about to continue search for other periodic advertiser.
The state was split because now Controller terminates sync ticker and
continues search for other periodic advertised. The split improves
readability and makes code easier to understand.
Signed-off-by: Piotr Pryga <piotr.pryga@nordicsemi.no>
In case of use of filtering based on: periodic advertising list and
CTE type, the synchronization can hang. That is possible if a periodic
advertiser uses wrong CTE type. In such situation the sync is not
released in ull_sync_done call. What more the sync->timeout_reload
is not cleared and Host is not able to cancel the synchronization.
The periodic advertising is in a semi-sync-established state.
There are no reports send to Host. Host can't use the sync set to
synchronize with other device. It is only able to terminate the
sync (call to ll_sync_terminate).
To fix the issue following changes should be applied:
- isr_rx_adv_sync_estab should call isr_rx_done_cleanup
with sync_term parameter in case the sync_ok isn't SYNC_STAT_ALLOWED.
In any case the CTE type is wrong, no matter is the periodic
advertising list filtering is enabled or not.
- ull_sync_established_report should set sync->is_term to true
in case the CTE type is not allowed. That change is required for devices
that do not support Direction Finding Extension. For those devices CTE
type based filtering is done in ULL by ull_sync_established_report
function. The sync->is_term should be set unconditionally, hence is
moved up in the function.
With these two changes done, ull_sync_done function will execute
sync_ticker_release in case the CTE has wrong type. ULL, depending on
notifications prepared by ull_sync_established_report, will follow up
on sync termination if required.

The periodic CTE_REQ disable command, requested by Host, may be locked
until connection is dropped due to missing CTE_RSP from peer device.
That is caused by implementation of CTE_REQ disable and CTE_REQ
control procedure handling.
The procedure is marked as active when CTE request was send to peer
device. It is marked as inactive after completion of the procedure.
That caused locking of CTE disable on a semaphore.
The BT 5.3 Core Spec, Vol 4, Part E, section 7.8.85 says the HCI_LE_-
Connection_CTE_Request_Enable should be considered active on a conne-
ction from when Host successfully issues the command with Enable=0x1
until a command is issued with Enable=0x0 or single LLCP CTE request
has finished (CTE_Request_Interval=0x0). Also there is a clarification
from BT SIG that the command with Enable=0x0 does not affect any
initiated LLCP CTE request. That means Controller is allowed to finish
already started procedure and it is not allowed to start new LLCP CTE
request procedure after completion of the command with Enable=0x0.
Taking that into account, there is no need to synchronize ULL and LLL
in regard of disable the LLCP CTE request while the procedure is
pending. Controller is free to complete the procedure or terminate it.
The change removes all code related with cte_req.is_active, disable
callback and waiting of ULL for LLL to finish the LLCP CTE request.
The ULL will complete the HCI_LE_Connection_Request_Enable with
Enable=0x0 immediately. In case the procedure is disabled in before
the response arrives, then further processing of the response is
dropped and the procedure context released.
The context is not released by the code responsible for disable
handling, to have single place where it is done.

Some of control procedures has set ctx->rx_opcode in rp_comm_tx
function to values that state there is an expected PDU.
This is not always true. In case of procedures that do not expect
any response from remote device, the ctx->rx_opcode should be set
to PDU_DATA_LLCTRL_TYPE_UNUSED.
In the worst cases scenario, when the same control procedure
is executed locally and remotely, correct response PDU may
cause an assertion in ull_cp_rx. It could happen because
of wrong ctx->rx_opcode value. A packet with opcode that is
set in remote and local control procedure context rx_opcode
will be treated as expected value for both. That is a situation
that cannot happen.

After update of the condition, the function call places
