Older value of 256 was introduced in 1.7 times. Testing on
BOARD=96b_carbon with 2 weeks old codebase however showed that TX
thread stack however can grow to 324 bytes. Finally, with the
latest master, following stacks are reported on BLE disconnect
(with CONFIG_INIT_STACKS enabled):
rx stack (real size 1024): unused 452 usage 572 / 1024 (55 %)
tx stack (real size 384): unused 16 usage 368 / 384 (95 %)
Two outcomes:
1. TX stack needs increase.
2. Over time, the stack usage grows, plus variations in SPI
drivers should also be taken into account.
So, increase the stack size to 416 bytes, to leave some headroom
beyond the immediate values seen on 96b_carbon.

A TCP FIN message is passed on to user apps as a tcp_received_callback
with a NULL pkt parameter. This means the connection is closing and
the app should do whatever cleanup it needs as there will be no further
callbacks for the current TCP connection.
Currently, if a HTTP client request doesn't receive a "body" which
the HTTP parser can use to trigger on_message_complete, then the request
will end up timing out and most apps will think an error has occurred.
Instead, let's handle the TCP FIN message and return the waiting
semaphore, leaving the app to deal with whatever has been set in the
current HTTP context response data (IE: http_status).
This fixes using HTTP client to send POST data to servers which
only respond with HTTP_OK status and no body.

Origin: SICS-IoT / Contiki OS
URL: https://github.com/sics-iot/lwm2m-contiki/tree/lwm2m-standalone-dtls
commit: d07b0bcd77ec7e8b93787669507f3d86cfbea64a
Purpose: Introduction of LwM2M client library.
Maintained-by: Zephyr
Lightweight Machine-to-Machine (LwM2M) is a protocol stack extension
of the Constrained Application Protocol (CoAP) which uses UDP
transmission packets.
This library was based on source worked on by Joakim Eriksson,
Niclas Finne and Joel Hoglund which was adopted by Contiki and then
later revamped to work as a stand-alone library.
A VERY high level summary of the changes made:
- [ALL] sources were re-formatted to Zephyr coding standards
- [engine] The engine portion was re-written due to the heavy reliance
on ER-CoAP APIs which are not compatible to the Zephyr CoAP APIs as
well as other Zephyr specific needs.
- [engine] All LWM2M/IPSO object data is now abstracted into resource
data which stores information like the data type, length, callbacks
to help with read/write. The engine modifies this data directly (or
makes callbacks) instead of all of the logic for this living in each
object's code. (This wasn't scaling well as I was implementing
changes).
- [engine] Related to the above change, I also added a generic set of
getter/setter functions that user applications can call to change
the object data instead of having to add getter/setting methods in
each object.
- [engine] The original sources shared the engine's context structure
quite extensively causing a problem with portability. I broke up the
context into it's individual parts: LWM2M path data, input data and
output data and pass only the needed data into each set of APIs.
- [content format read/writer] sources were re-organized into single
.c/h files per content formatter.
- [content format read/writer] sources were re-written where necessary
to remove the sharing of the lwm2m engine's context and instead only
requires the path and input or output data specific to it's
function.
- [LwM2M objects] re-written using the new engine's abstractions

In the 08 Feb 2017 V1.0 LwM2M specification page 80 mentions: in
response to a "Notify" operation for which it is not interested in
any more, the LwM2M Server can send a "Reset Message".
Leshan server sends this CoAP RST response and it does not contain
the originating message token (which is also how the packet flow looks
on page 81 of the LwM2M spec). Using the current ZoAP sources, the
client has no way of matching back to observation which needs to be
cancelled.
Let's add a match for message ID of a reply where there is no token
to handle this case.

There are two kinds of HCI implementations. Bluetooth drivers in
drivers/bluetooth that implement HCI by using a wired serial
transport layer to talk to an external controller chip. And a
bluetooth controller in subsys/bluetooth/controller that directly
talks to an internal on-chip controller node.
Currently, when the the subsys/bluetooth/controller is used there
still exists exposed to the user a bluetooth driver configuration
menu, even though no external bluetooth driver is in use. This is due
to a dependency on certain configs in driver/bluetooth that are needed
even though no external controller is used.
This patch moves one of these configs, BLUETOOTH_HCI_RESERVE, from
drivers/bluetooth/hci/Kconfig to subsys/bluetooth/host/Kconfig such
that eventually we can omit the entire Bluetooth driver menu option.
This re-organization does not change when the config can be enabled.

ReST defines interpreted text roles where text enclosed by single quotes
can be "intrepreted", for example :ref:`some name` becomes a link to
a label anywhere in the doc set named "some name", :c:func:`funcname()`
becomes a link to the API documentation for "funcname", and
:option:`CONFIG_NAME` becomes a link to, in our case, the documentation
for the generated Kconfig option.
This patch fixes uses of `some name` (without a role) by either adding
an explicit role, or changing to ``some name``, which indicates inline
code block formatting (most likely what was intended).
This is a precursor to changing the default behavior of interpreted
text to treat `some name` as :any:`some name` (as configured in
doc/conf.py), which would attempt to create a link to any available
definition of "some name".
We may not change this default role behavior, but it becomes an option
after the fixes in this patch. In any case, this patch fixes incorrect
uses of single-quoted text (possibly introduced because GitHub's
markdown language uses single-quoted text for inline code formatting).

The nRF5 AAR requires the packet pointer to be placed exactly 3 bytes
before the beginning of the address. Since we don't use the S1 extra
length byte, substract one from the address of the radio packet pointer.

Historically, stacks were just character buffers and could be treated
as such if the user wanted to look inside the stack data, and also
declared as an array of the desired stack size.
This is no longer the case. Certain architectures will create a memory
region much larger to account for MPU/MMU guard pages. Unfortunately,
the kernel interfaces treat both the declared stack, and the valid
stack buffer within it as the same char * data type, even though these
absolutely cannot be used interchangeably.
We introduce an opaque k_thread_stack_t which gets instantiated by
K_THREAD_STACK_DECLARE(), this is no longer treated by the compiler
as a character pointer, even though it really is.
To access the real stack buffer within, the result of
K_THREAD_STACK_BUFFER() can be used, which will return a char * type.
This should catch a bunch of programming mistakes at build time:
- Declaring a character array outside of K_THREAD_STACK_DECLARE() and
passing it to K_THREAD_CREATE
- Directly examining the stack created by K_THREAD_STACK_DECLARE()
which is not actually the memory desired and may trigger a CPU
exception

In order to make sure that the ISR never gets an incomplete or partial
local RPA, use pointers to share the local RPA between thread mode and
ISRs. Pointer updates are guaranteed to be atomic at least on ARM
Cortex-M.
Additionally add support for using local RPAs when initiating a
connection or sending a scan request.

This commit introduces controller-based privacy for both the scanner and
the initiator roles. All the features in the specification are
implemented except:
* RPA resolution for directed advertising (TargetA address)
* RPA generation for scan requests and conn ind packets
Follow-up patches will cover the 2 items of functionality still missing
from the basic implementation. Hosts not using controller-based privacy
should not be affected by this change.

As ticker can only drift in 32kHz units, the slave Rx
window should consider a +/- one 32kHz unit in addition to
+/- 16us jitter of the master. Hence, for the current
implementation the slave Rx window jitter is +/- 48us.
Future improvement can be done by using remainder of 32kHz
unit drift to reduce this jitter to +/- 16us.
With this fix 20ppm clock accuracy passes conformance TIM
tests (else 251-500ppm had to be used).
Problem was not seen in real life as master do not have a
+/- 16us jitter.
