This commit adds a `NeighborTable` class which provides helper methods
dealing with neighbor, e.g., finding a `Neighbor` (i.e., a `Child`
from `ChildTable`, a `Router` from `RouterTable`, or parent or parent
candidate entries), or iterating through all neighbors. These methods
use the newly added `Neighbor::AddressMacther` to simplify the
implementation. The `NeighborTable` methods replace the similar ones
in `Mle` and `MleRouter`.
This commit implements Thread based Joiner Advertisement from Joiner
side, including:
- A new MeshCop TLV: Joiner Advertisement TLV which includes IEEE OUI
and the Advertisement Data.
- New APIs to set Joiner Advertisement which will be sent along with
Discovery Request messages.
This commit enhances the filtering behavior of Discover Scan. When
filtering is enabled, MLE Discovery Responses with steering data
(bloom filter) not containing a set of bloom filter indexes are
filtered. This commit updates the `DiscoverScanner::Discover()` to
allow filter indexes used for filtering to be optionally specified by
the caller. It can be set to NULL (for default behavior) where the
hash of factory-assigned EUI64 of the device would be used to derive
the bloom filter indexes
This commit adds new class `DiscoverScanner` which implements the MLE
Discover Scan process (moving and simplifying all the code related to
this from `Mle` and `MeshForwarder` into same file/class).
This commit defines a new enum type `Mle::DeviceRole` mirroring the
public `otDeviceRole` enumeration. The enumerator in the new type
follow `kRole{Value}` style and intended for use in the core modules.
It also adds helper method in `Mle`, `IsChild()`, `IsRouter()`,
`IsLeader()`, etc to check the current device role.
This commit improves usability of Network Diagnostic API by:
- Define native structures to represent various Network Diagnostic TLV
values.
- Add facility function otThreadGetNextDiagnosticTlv to parse plain
otMessage into structured data.
- Dump parsed DIAG_GET.ans/.rsp message in readable format for
networkdiagnostic CLI command.
This commit adds `LeaderData` (subclass of `otLeaderData`) to store
the info from Leader Data TLV. It also adds `ReadLeaderData()` to
read Leader Data TLV from a message.
This commit adds a new OpenThread specific `OT_ASSERT()` macro along
with a new config OPENTHREAD_CONFIG_ASSERT_ENABLE option which allows
the assert to be enabled or disabled. This allows a release build to
consider disabling the assert reducing code size. This commit also
adds a new travis (simulation platform) build with asserts disabled.
This commit introduces the first Thread 1.2 feature - enhanced keep
alive.
This commit also introduces the build config
OPENTHREAD_CONFIG_THREAD_VERSION to include/exclude Thread 1.2 code.
This commit adds `Time` class which represents an instance of time
(it is a simple wrapper over a `uint32_t` corresponding to a
numerical time value). The `Time` class provides helpful operator
overloads:
- Operators `+` and `-` with a `Time` instance and a `Duration` to
get a `Time` instance after or before.
- Operator `-` with two `Time` instances to calculate the `Duration`
duration between two time instances.
- Operators `<`, `<=`, `>`,'>=', '==' and `!=` to compare two `Time`
instances. They correctly handle the wrapping of numeric time value.
The core modules are updated to use the new `Time` and `Duration`
types which help make the code simpler. This commit also updates the
unit test `test_timer` to add test cases for newly added types.
This commit adds `Mac::NetworkName` class as C++ wrapper over the
`otNetworkName`. It also adds `NetworkName::Data` to represent the
network name as a pointer to a char array buffer (not necessarily null
terminated) with a given length. This representation is used by
`Mac::BeaconPlayload` and `MeshCop::NetworkNameTlv`. This commit also
adds a unit test for `Mac::NetworkName` class.
This commit adds a `Mle::DeviceMode` class which is warpper over
a device mode bitmask (`uint8_t`) and provides the common helper
functions like `IsRxOnWhenIdle()`, `IsFullThreadDevice()`, etc.
This commit fixes a bug in the commissioner when a joiner's expiration
time has alerady elapsed.
This commit also introduces convenience methods for computing time
elapsed and diffs.
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 simplifies the `Mle::Start()` by combining its parameters.
With the new definition `Start()` would always try to reattach using
any saved active/pending dataset unless it is asked to attach on an
announced network (i.e., `aAnnounceAttach` is `true`).
This commit adds support for a set of MLE counters (e.g., counters to
track number of times device entered different roles, or counters
tracking number of attach attempts, partition ID or parent changes).
The existing router table allocated a router entry for every possible router
id value (63). Beacuse Thread only allows at most 32 active routers in a
given network, allocating 63 router entries is wasteful. This commit
allocates only 32 router entries and dynamically manages the pool of router
entries.
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).
