15dfec4df6 Bluetooth: host: Fix ECC thread stack size too small
Fix ECC thread stack size which is to small to account for the worst
case scenario. When an interrupt happens at the point where the ECC
thread is at the highest stack size usage pushing the thread context
to service the ISR causes a stack overflow.

Increase the ECC thread stack size by atleast the size of the basic
stack frame of 32 bytes aligned on 8 byte for ARM architectures.

22068d4967 Bluetooth: services: Do not set current object until selected
Do not make the first object added to the object transfer server the
current (=selected object).  This leads to the server having no
current object until one is selected by the client.

This solves a startup issue where the selected callback is not called
by the server if the first object selected by the client happens to be
the same object as the object that was first added to the server.  In
that case, the user of the OTS does not know which object is selected,
and therefore may not be able to supply the correct data later.

This has not caused issues so far, but when the ref member
of the struct ull_hdr if placed in the beginning of a

bf942bdf9a Bluetooth: Mesh: Report configured LPNTimeout in cfg_srv
Changes lpn_timeout_get behavior in the config server to report the
configured LPN timeout, instead of the currently remaining timeout time.
According to the Bluetooth Mesh Profile specification, section 4.2.21,
the PollTimeout list is a list of the PollTimeout timer values, and
according to table 4.32 in this section, values 1-9 are prohibited.
Although this is not explicitly stated, this indicates that the
PollTimeout value is the configured poll timeout time - not the time
remaining until the timeout value expires. This patch changes the
implementation to reflect this.

820cfc52ad Bluetooth: Mesh: Rework publication timer
Periodic publication would previously build and send the first
publication inside the bt_mesh_model_pub() function, before cancelling
and rescheduling the next publication. The timer handler would only
handle retransmissions, and would abandon the rest of the publication
event if one of the packets failed to send.

This design has three issues:
- If the initial timer cancel fails, the publication would interfer with
  the periodic publication management, which might skip an event or
  send too many packets.
- If any of the messages fail to publish, the full publication event
  would be abandoned. This is not predictable or expected from the API.
- bt_mesh_model_pub() required 384 bytes of stack to build the message,
  which has to be factored into all calling threads.

This patch moves all transmission into the publication timer by
replacing k_work_cancel with a single k_work_reschedule(K_NO_WAIT). It
also changes the error recovery behavior to attempt to finish the full
publication event even if some of the transmissions fail.

Split out from #33782.

07278fc98f Bluetooth: controller: Guard against race in conn. establishment
In the time between a NODE_RX_TYPE_CONNECTION node is sent from LLL and
demuxed in ULL, an ADV role disable may be executed.
This makes the LLL data referenced in the node NULL/invald, and
ull_conn_setup would operate on invalid data.

This commit introduces a check in ADV disable to disallow the operation
(including conn invalidation), if a connection has been initiated.

To prevent pipeline-queued prepares from advertising after disable has
been initiated, set 'cancelled' flag for immediate signalling to LLL.

27c26eb1e7 Bluetooth: controller: Fix LLL done and pipeline enqueue race
There is a race between the pipeline enqueue by the ULL
context when processing the LLL done event, and the
pipeline queue by the ticker timeout for a new radio
event. This caused an already enqueued event prepare to be
placed after the newly arrived request to enqueue a prepare
by ticker timeout.

Fix this race by placing the new prepare in the pipeline
instead of starting the event, when ULL is still processing
the LLL done event.

As ticker timeout and ULL processing of LLL done event are
in the same ULL_HIGH context, the pipeline handling is safe
with the order of prepares maintained correctly.
