This commit changes how the objects in OpenThread access each other.
It adds a template `Get<Type>()` method in `InstanceLocator`. This
method returns a reference to a given `Type` object belonging to the
OpenThread instance (e.g. `Get<MeshForwarder>()` returns a reference
to `MeshForwarder` object on the OpenThread instance). The
`InstanceLocator` is used as base class of all OpenThread classes so
every class can easily access any other object. This commit also
changes how the main instance is retrieved in `InstanceLocator` for
the single-instance case. The method `GetInstance()` directly uses the
raw buffer `gInstanceRaw`. This change helps make the `GetInstance()`
and in turn all `Get<Type>()` methods in-line. This commit also
removes the existing getters across all classes to use the new
`Get<Type>()` model.
This commit enhances the SLAAC support in OpenThread core. It contains
the following changes and features:
The `Utils::Slaac` class is updated to include all the related code
for managing SLAAC addresses (e.g., `Slaac` class maintains the
address buffer and directly subscribes to `Notifier` to listen for
Network Data changes to update SLAAC addresses).
The SLAAC address module is changed to support and use semantically
opaque IID generation algorithm (RFC 7217) instead of random IID
generation. This ensures that SLAAC addresses are random but stable
(i.e., the same SLAAC address is added on a device for the same
prefix) and aligns the implementation with Thread specification
requirement.
The semantically opaque IID generation logic is updated to follow RFC
7217 with SHA-256 as the pseudo-random function, and a 256 bit secret
key (generated once using true random number generator and saved in
non-volatile settings).
A new feature is added to allow SLAAC support to be enabled or
disabled during network operation. When enabled, SLAAC addresses are
generated and added to the interface. When disabled, any previously
added SLAAC address is removed.
This commit also adds "SLAAC prefix filter" feature which allows
OpenThread users to register a filter handler with SLAAC module. The
handler is invoked by SLAAC module when it is about to add a SLAAC
address based on a prefix. The returned boolean value from the handler
determines whether the address should be filtered or not.
This commit makes the following changes: It defines the public
`otInstance` as an empty opaque structure which is used by all public
C OpenThread APIs. It defines a new class `ot::Instance` (inheriting
from `otInstance) which is then used in core source files. The
functionality related to the instance is also moved/added into the
newly added `Instance` class (as class/static or member methods).
This commit simplifies the config header files includes in
OpenThread core and non-public source files. With this change the
"openthread-core-config.h" becomes the main config header file. This
header file includes all other config ones:
1) The `configure` generated `<openthread/config.h>;
2) The project specific one by `OPENTHREAD_PROJECT_CORE_CONFIG_FILE`;
3) The "openthread-core-default-config.h" defining default settings.
With the change in this commit, all header files include "openthread-
core-config.h" as the first `#include`, and in `.cpp` files, the first
`#include` continues to be the unit's corresponding header file. The
new model ensures that the configuration settings are visible and
consistent in all the source files. This commit also updates the
style guide document accordingly.
