In Thread 1.2, it is possible to receive an IEEE 802.15.4-2015
packet. Per specification, receiver should acknowledge this packet
with an IEEE 802.15.4-2015 ACK(Enh-ACK). This Enh-ACK can include
header IE with it and requires security enabled bit in FCF be set to
true. It is impractical for the host to generate the Enh-ACK and send
to RCP for transmission within AIFS time(192us). So RCP should prepare
the Enh-ACK by itself, which requires it to fill in the frame counter
and do the encryption/authentication. This commit tries to address the
need of transmission security/authentication by including the
following changes,
- Move Key ID mode 1 AES-CCM* related functions from MAC layer to
SubMac layer, which is mirrored in RCP.
- Distribute the MAC key and MAC key ID to RCP in posix app using
newly added spinel properties.
- Make it possible for radio(either in radio driver or hardware) to do
transmission AES-CCM* if the platform supports by adding radio
capability OT_RADIO_CAPS_TRANSMIT_SEC.
- Enable this for RCP mode on simulation platform.
This commit enables building OpenThread deb packages:
* openthread-simulation: simulation of OpenThread
* openthread-daemon: daemon of OpenThread Host
* openthread-standalone: standalone binaries of OpenThread Host
platform-utils has a dependency on the core ot library, which was
causing the build to fail. I have resolved this by making
platform-utils an 'object library', which means the object files
will always be used by the linker, preventing the 'smart linker'
errors that occur with ld and cyclic dependencies.
I also provided a static (.a) implementation of the library in case
any non-cmake project wanted to consume the results (at which point
that project can deal with the dependency as it wishes).
So now it is up to the 'platform layer' to include the 'platform utils'
objects inside its own library if it requires them. I have implemented
this for the current cmake example platforms.
This commit adds a new log output model for NCP to use a newly added
spinel stream log property. `OPENTHREAD_CONFIG_LOG_OUTPUT_NCP_SPINEL`
can be used to be select the new log output model.
This commit defines a new spinel property `SPINEL_PROP_STREAM_LOG`
which provides streaming of formatted log string from NCP along with
an optional metadata structure. OpenThread log level and log region
are included as part of the metadata.
This commit also updates the `toranj` configuration header file to
use the new log output model.
Pseudo resets allow for `otPlatReset()` to reset the OpenThread state
without resetting the chip. This is important if the SoC is presenting
itself as a USB device.
The build option `OPENTHREAD_PLATFORM_USE_PSEUDO_RESET` can be used to
force this feature to be enabled or disabled by setting it to `1` or
`0` accordingly. Otherwise it will be set to a platform-specified
default value.
The existing platform.h is really a part of the examples and not a part of
OpenThread core. This commit moves the platform.h out of the public API
and into the examples directory.
* [ncp] Transforming spinel frames between AP and NCP
NCP Spinel Transformer allows to transform spinel frames sent between
Application Processor (AP) and Network Co-Processor (NCP).
Spinel frames can be transformed by using transformer library
(or libraries) implementing spinel_transformer.hpp. Libraries
can be specified using option --with-ncp-spinel-transformer-libs.
Addidionaly, transformer's outbound buffer can be changed if needed,
using option --with-ncp-spinel-transformer-outbound-buffer-size.
Thread (and OpenThread) does not employ any form of transmit power control.
As a result, while OpenThread provides APIs to control transmit power, it
simply buffers and passes the transmit power value straight through to the
radio.
Currently, the transmit power APIs allow specifying an int8_t in units of
dBm. This is overly constraining for platforms that have more advanced ways
of configuring the transmit power.
This commit removes the transmit power configuration from the core. This
provides better flexibility in platform-specific ways to configure transmit
power.

Previously, a global 'map.map' filename was used. However, when
building FTD and MTD versions of a given application, the 'map.map'
files would overwrite each other. This commit gives different filenames
to each .map file for a given binary.
