This commit adds a new module `Uptime` which tracks the number of
milliseconds since OpenThread stack initialization as an `uint64_t`
value. It also adds public OT APIs to get the current uptime value
(either as the number of milliseconds or in human-readable string
format like "2 days 12:45:12.762"). A CLI `uptime` command is also
added. This feature can be enabled using the newly added config
option `OPENTHREAD_CONFIG_UPTIME_ENABLE` (or the related CMake
`OT_UPTIME` option).
This commit adds History Tracker feature and its CLI support. This
feature records history of different events as the Thread network
operates (e.g., history of RX and TX IPv6 messages or network info
changes).
Recorded entries are timestamped. When the history list is read, the
timestamps are given as the entry age relative to the time the list
is being read. For example in CLI a timestamp can be shown as
`02:31:50.628 ago` indicating the entry was recorded 2 hours, 31 min,
50 sec, and 628 msec ago. Number of days is added for events that are
older than 24 hours, e.g., `31 days 03:00:23.931 ago`. Timestamps use
millisecond accuracy and are tacked up to 49 days. If an event is
older than 49 days, the entry is still tracked in the list but the
timestamp is shown as old or `more than 49 days ago`.
The `HistoryTracker` currently maintains 3 lists. The Network Info
history tracks changes to Device Role, Mode, RLOC16 and Partition ID.
The RX/TX history list records information about the received/sent
IPv6 messages:
- Message type (UDP, TCP, ICMP6 (and its subtype), etc.)
- Source and destination IPv6 addresses and port numbers
- IPv6 payload length
- The message checksum (for UDP, TCP, or ICMP6).
- Whether or not the link-layer security was used
- Message priority: low, norm, high, net (for control messages)
- Short address (RLOC16) of neighbor who send/received the msg
- Received Signal Strength (in dBm) for RX only
- Radio link info (15.4/TREL) on which msg was sent/received
(useful when `OPENTHREAD_CONFIG_MULTI_RADIO` is enabled)
Config `HISTORY_TRACKER_EXCLUDE_THREAD_CONTROL_MESSAGES` can be used
to configure `HistoryTracker` to exclude Thread Control message
(e.g., MLE, TMF) from TX and RX history.
The number of entries recorded for each history list is configurable
through a set of OpenThread config options, e.g., number of entries
in Network Info history list is specified by OpenThread config option
`OPENTHREAD_CONFIG_HISTORY_TRACKER_NET_INFO_LIST_SIZE`. The
`HistoryTracker` will keep the most recent entries overwriting oldest
ones when the list gets full.
This commit also adds support for `HistoryTracker` in CLI. The CLI
commands provide two style for printing the history information: A
table format (more human-readable) and list style (better suited for
parsing by machine/code). `README_HISTORY.md` is added to document
the commands and the info provided by each history list entry.
This commit also adds `test_history_tracker.py` test-case which
covers the behavior of `HistoryTracker`.
This commit implements a new feature "Network Data Publisher" which
provides mechanisms to limit the number of similar entries (service
and/or prefix) in the Thread Network Data by monitoring the Network
Data and managing if or when to add or remove entries. This feature is
enabled using `OPENTHREAD_CONFIG_NETDATA_PUBLISHER_ENABLE` config, or
`NETDATA_PUBLISHER` in autoconf, or `OT_NETDATA_PUBLISHER` cmake
option.
This commit adds support for publishing DNS/SRP anycast/unicast
service, on-mesh prefix, and external route prefix entries.
When there is a request to publish an entry, the `Publisher` monitors
the Network Data and counts the number of similar entries. If there
are fewer entries than a desired target number, the entry is added
after a short random delay.
If there are too many similar entries, `Publisher` starts the process
of removing its own entry (again after some random wait time). When
removing entries, certain entries are preferred over others (e.g., an
entry from a router over one from an end-device or if they are from
the same type of node, the one with smaller RLOC16). If `Publisher`
determines that its own entry is a preferred one, it adds an extra
wait time before removing its entry. This gives higher chance for a
non-preferred entry from another device to be removed before removing
a preferred entry which helps towards quicker convergence of the
process to the desired number of entries.
On-mesh prefix and external route entries have a "preference" field.
When publishing such an entry, a matching entry in the network data is
counted only if its preference is same or higher than the entry's
preference. This ensures that a device with a higher preference entry
publishes its entry even when there are many lower preference similar
entries in the network data (potentially causing a lower preference
entry to be removed).
This commit also adds `test_netdata_publisher.py` to verify the
behavior of the `Publisher`.
This commit fixes reporting expect failures by adding fail on error
flag to the ot_exec_expect_script function in script/test script.
This commit also fixes failing expect tests and removes expect tests
on macOS for unstable issues.
The default Thread version has been set to 1.2 when building. Our test
script which checks building hasn't been updated accordingly. This
commit fixes this error.
This commit splits OPENTHREAD_CONFIG_MLE_LINK_METRICS_ENABLE macro
into two subsequent ones:
- OPENTHREAD_CONFIG_MLE_LINK_METRICS_SUBJECT_ENABLE
- OPENTHREAD_CONFIG_MLE_LINK_METRICS_INITIATOR_ENABLE
This addresses `clang-tidy` warning for unused `using` statement. This
commit also ensures `OT_DNSSD_SERVER` is enabled in `make-pretty`
script and therefore covered by github action `build pretty`
workflow.
Summary of changes:
- Enable building OpenThread RCP image on the Raspberry Pi (aarch64)
directly (using Ubuntu)
- Fix problem with not having access to the /opt folder as a user
List of changes:
- modified Autotools, CMake and Android build systems
- increased heap size as new version requires additional 64B
- replaced deprecated API (mbedtls_ecdsa_sign_det)
- removed workaround with defining mbedtls_ecp_restart_ctx
This commit updates `toranj/build.sh` script for posix based builds to
generate CLI executable. It also updates the posix platform to provide
log functionality when `LOG_OUTPUT` is set to `LOG_OUTPUT_APP`.
This commit also adds CI build checks for multi-radio and TREL build
configurations under posix platform.
Since OT_TREL is going to be set to ON in OTBR, this commit makes sure
we test OTBR with TREL off.
Also removed -DOTBR_DNSSD_DISCOVERY_PROXY=ON since it's now ON by
default.
The POSIX NCP app(ot-ncp) is simulating of NCP with an RCP. With the
latest otbr-agent, this is not needed any more. It is only used in CI
tests. This commit removes the app to save maintenance efforts.
This commit implements DNS-SD Discovery Proxy.
- Implemented DNS-SD Discovery Proxy functionalities - OT part
- Fixed an memory issue of NameCompressInfo (introduced in #6155 , but
somehow revealed by this commit)
Some implementation details:
- Discovery Proxy subscribes to services/service instances/hosts
through callbacks set by a public OT API. It is up to the platform
mDNS implementation to collect service instance/host information and
notify OT via a public OT API.
- Discovery Proxy can handle DNS browsing of one service or DNS
resolving of one service instance/host. We leave browsing multiple
services or resolving multiple service instances/hosts for future
enhancements if necessary.
This commit adds CMake support for the efr32 platforms and Silicon
Labs gecko_sdk_suite. It also adds the option to build the efr32
sleepy-demo apps.
Other changes:
- jlinkrtt: remove NordicSemi specific options/definitions/includes
from default build
- Remove old include dirs that don't exist anymore from efr32 automake
files
This commit removes application library CLI/NCP dependency on platform
layer UART APIs. Instead, application layer provides callbacks sending
CLI/NCP data.
With this change, platforms with native support for formatted output
can simply implement the CLI output callback with something like
`vprintf()`.
