This commit adds the Multicast Listener Table for BBR:
- Implements Multicast Listener Table on BBR
- Adds registered MAs to MulticastListenerTable
- Reject when the table is full or the multicast address is invalid
and return failed status
- Respond with unsuccessful status along with failed addresses
- Expire Listeners from MulticastListenerTable per second (using
MinHeap for better performance)
- MLR enhancement
- Re-register only failed multicast addresses (used to register all
registering multicast addresses)
- Reference Device only APIs
- Some APIs are defined for reference devices and tests.
- Add tests
- Add unit test: test_multicast_listener_table.cpp (runs for 1.2-bbr
only)
- Add functional tests
This commit adds one test to verify that if a node subscribed MAs when
there is no PBBR in the network, it should still be able to send
MLR.req after PBBR is enabled.
This is a case that wasn't tested in existing tests.
With Thread 1.2, it is possible to receive an Enh-ACK with security
enabled. This commit:
- Move receive AES CCM related code to Frame class.
- Verify received Enh-ACK in Mac layer. If MIC check failed, the
transmitted frame will be marked as OT_ERROR_NO_ACK.
To enable CSL, it is necessary to get received Enh-ACK timestamp so
that the next sample time could be calculated with this timestamp and
CSL phase in CSL IE.
This commit removes the config setting
OPENTHREAD_CONFIG_MAC_CSL_RECEIVER_ENABLE automatically when it's 1.2
and MTD. The reason is that it's in core config and it's also used in
platform (radio) which cannot access core config.
If CSL_RECEIVER is not set in options in cmake and it's 1.2, then in
core config, OPENTHREAD_CONFIG_MAC_CSL_RECEIVER_ENABLE would be turned
on if it's MTD. While in platform, it's not turned on. And then there
would be a link issue.
A SSED uses the Child Update Request to start CSL synchronization. If
the CSL Channel TLV is not present in the message, the parent assigns
the Thread Network channel as the CSL channel for this child during
the attachment.
However, it may happen that a child changes its CSL channel to a
different one with a Child Update Request and decides to keep using
it. In a subsequent Child Update Request it could omit the CSL Channel
TLV (no changes) but the parent would change its CSL channel to the
Thread Network channel. This commit avoids that.
The `Message` data is stored in a sequence of linked-listed `Buffer`
instances. When reading or writing data in the `Message`, the internal
implementation iterates over the `Buffer` list and updates the data in
chunks. This commit adds two helper methods `GetFirstChunk()` and
`GetNextChunk()` to get first/next data chunk (contiguous buffer)
corresponding to a given offset and length into the message. These
helper methods are then used to simplify `Read()`, `Write()`, and
`UpdateChecksum()` methods. The unit test `test_message` is also
updated to verify reading and writing data at different offsets and
lengths.
This commit adds `TimeTicker` class which emits periodic ticks (with
one second period interval) to a set of registered tick receiver
modules. The `TimeTicker` would invoke `HandleTimeTick()` method
periodically on the registered receiver objects.
The `TimeTicker` model helps simplify the implementation of many
modules (such as `MeshForwarder`, `MleRoutuer`, `AddressResolver`,
`Ip6`, `DuaManager`, etc) which require periodic update/check of some
state (avoid each class using its own timer).
OT_CONFIG was used to specify a customized OpenThread core config file
which is only included by OpenThread core library. This commit changes
the behavior so that it specifies the OPENTHREAD_CONFIG_FILE which is
used by all components of OpenThread including the core library.
This commit contain a list of smaller enhancements in `Ip6` modules:
- Simplify `Ip6::Header` removing the PoD definition and providing
`enum` constants for the byte offset to different fields in the header
(replacing/removing static methods).
- Declare some of the `Ip6` methods as `private`.
- Remove error logs (not used/applicable anymore).
- Simplify checking of `destPort` in `ProcessReceiveCallback()`.
- Specify `int` size of `enum` definitions (declare internally-used
`enum`s a `private`).
- Add unit test `TestIp6Header()`.
This commit implements the CSL feature in Thread 1.2.
- Add macro definitions for low power to control the compiling of
source code.
- Add data and methods for running CSL in Mac and SubMac. This mainly
includes setting CSL parameters, starting/stopping CSL, and the
timer handling process.
- Add otPlatTimeGetAPI and implementation.
- Add CSL transmission implementation. CSL transmission is a new kind
of transmission, the related definition and implementaion for the
whole transmitting process is added.
- Add calling of start/stop CSL in certain cases.
- Implement CSL synchronization maintainence. If a CSL cordinator
didn't get a frame containing CSL IE for CSLTimeout, the CSL
receiver is regarded as de-synchronized.
- Add Cli interface for using CSL.
- Implement enhanced Ack with IE. The original code can only generate
auto ack for Imm-Ack. As CSL requires CSL IE included in enhanced
ack. This PR implements it.
- Add basic functional test for CSL transmission. More tests
corresponding to test plan would be added later.
It is possible that log is printed before the Interpreter (UART or
CONSOLE) object is created when FULL LOGS is enabled. In such case, OT
crashes. This commit fixes this bug.
In 802.15.4-2015 spec Table 7-2, it is possible to receive frame with
destination address but without destination PAN ID. This commit
changes the address filter function to avoid dropping such frames.
Use the config specified on the command line, so that overriding this
with a project specific config doesn't cause preprocessor macro
redefinition errors.
The `ThreadLinkInfo` mirrors the `otThreadLinkInfo` definition.
It is mostly used in `MeshForwarder` and `Mle` class. Here are
some related helper methods:
- New helper methods in `Ip6::MessageInfo` to get and set the
link info as `ThreadLinkInfo`.
- Helper method `ThreadLinkInfo::SetFrom()` allows it to be set
from a given `Mac::RxFrame`.
- Helper method `Message::SetLinkInfo()` allows message link info
related fields (in message metadata) to be set/updated from a
given `ThreadLinkInfo`.
This commit adds a group of `Init` methods in `NetifUnciastAddress`
for common initializations of a unicast address with different
parameters (origin, scope, prefix length, and preferred/valid flags).
This commit makes packet verification to run for multiple times.
Since now we are developing many packet verification scripts, this
commit can help us reduce the chance of merging a verification code
that could fail by chance, which is very often for packet verification
code.
This commit addresses an issue where the MLE Link Accept message may
be too large to fit within a single IEEE 802.15.4 frame. Thread
requires any MLE message transported using 6LoWPAN fragmentation to
also enable IEEE 802.15.4 MAC frame security. However, the purpose of
MLE Link Accept messages is to establish a secure link and cannot
itself be transported with IEEE 802.15.4 MAC frame security enabled.
An MLE Link Accept message may carry a Route64 TLV that has a length
dependent on the number of active routers in the network. When there
are many active routers, the Route64 TLV is large and the MLE Link
Accept message can no longer fit within a single IEEE 802.15.4
frame. The side effect is that a router coming out of reset will not
be able to diretly restore its router role and must first attach as an
end device.
This commit limits the size of a Route64 TLV when included in MLE Link
Accept messages. When the number of active routers is above a
threshold, some routers will be elided from the Route64 TLV and the
Router ID Sequence value is decremented. This allows the device coming
out of reset to restore its router role and retrieve the current
Route64 TLV in a subsequent message exchange.
