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).

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 many networking tests we had to configure SLIP in the prj.conf
leaving those configurations Qemu specific. This change enables SLIP for
QEMU targets automatically and allows reuse of prj.conf for multiple
boards.
Additionally, the TUN options is removed. This option was not used
anywhere.
To enable self-contained networking tests that do not depend on SLIP, we
introduce the new option NET_TEST which disables TAP and allows testing
in QEMU without the need for a host interface.

Add an initial implementation for the Bluetooth Mesh Profile
Specification. The main code resides in subsys/bluetooth/host/mesh and
the public API can be found in include/bluetooth/mesh.h. There are a
couple of samples provided as well under samples/bluetooth and
tests/bluetooth.
The implementation covers all layers of the Bluetooth Mesh stack and
most optional features as well. The following is a list of some of
these features and the c-files where the implementation can be found:
- GATT & Advertising bearers (proxy.c & adv.c)
- Network Layer (net.c)
- Lower and Upper Transport Layers (transport.c)
- Access Layer (access.c)
- Foundation Models, Server role (health.c & cfg.c)
- Both PB-ADV and PB-GATT based provisioning (prov.c)
- Low Power Node support (lpn.c)
- Relay support (net.c)
- GATT Proxy (proxy.c)
Notable features that are *not* part of the implementation:
- Friend support (initial bits are in place in friend.c)
- Provisioner support (low-value for typical Zephyr devices)
- GATT Client (low-value for typical Zephyr devices)

This patch fixes a regression which the original patch introducing
this code (improving concurrent connection handling) had on
*sequential* connection handling. Without this patch, with the
default CONFIG_NET_TCP_BACKLOG_SIZE of 1, after each connection
request, there was 1s (ACK timeout) "dead time" during which new
connection wasn't ptocessed.
This is because k_delayed_work_remaining_get() was checked the
wrong way. But there's no need to use k_delayed_work_remaining_get()
at all, instead just call k_delayed_work_cancel() and dispatch on
its return code.
Note that there's still a problem of synchronizing access to
the global array tcp_backlog, as worker (which modifies it) may
preempt packet handling code (which also modifies it).

Upcoming memory protection features will be placing some additional
constraints on kernel objects:
- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.
Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.
It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.
There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.
k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.
