This commit adds a new file
`tests/scripts/thread-cert/border_router/nat64/test_upstream_dns.py`
to test scripts for testing the DNS forwarding functions.
The test adds a record `test.domain` to the bind9 interface since when
adding to DNSSD tests, the OpenThread's DNSSD server will be conflict
with the Docker's DNS forwarding functions.
This commit adds `otNetDataGetNextLowpanContextInfo()` to iterate
through the list of LoWPAN Context entries in Thread Network Data
providing info about the prefix, its LoWPAN Context ID and Compress
flag (relating to `ContextTlv` sub-TLVs of `PrefixTlv`s in Network
Data).
This commit also updates CLI command `netdata show` to list the
context IDs in addition to prefixes, routes, and services.
This commit updates `MleRouter to send an immediate MLE Advertisement
on promotion to `router` role and assignment of new Router ID. This
helps inform our former parent of our newly allocated Router ID and
cause it to reset it own advertisement trickle timer. This can help
speed up the dissemination of the new Router ID to other routers. It
can also help with quicker link establishment with our former parent
and other routers.
It also removes tx of multicast Link Request (including its delay
mechanism) upon promotion to `router` role.
It also updates `Mle` so if we receive an MLE advertisement from a
former child (which is recently get promoted to router) to accept it
immediately and copy the info from `Child` entry to `Router`.
Finally this commit updates the following test-cases which are
impacted by the changes above (e.g., skipping the checks for
multicast Link Request):
- `v1_2_router_5_1_1`
- `Cert_5_1_01_RouterAttach`
- `Cert_5_2_04_REEDUpgrade`
- `Cert_5_5_02_LeaderReboot`
- `Cert_5_5_05_SplitMergeREED`
This commit contains changes to child supervision feature. It adds a
new mechanism for a child to inform its desired supervision interval
to its parent. A new optional MLE TLV is added with type 27 and value
of `uint16_t` indicating the supervision interval in seconds. This
TLV is included in MLE Child ID Request and MLE Child Update Request
(sent from the child). The parent echoes back this TLV in the
corresponding responses to indicate that it supports supervision. This
commit changes the parent implementation to track the supervision
interval per child.
This commit also updates the OT public APIs along with the related
CLI commands:
- API now allows the supervision interval to be set on a child.
- New field in `otChildInfo` to indicate the child's supervision
interval.
- New counter is added to track the number of supervision check
timeouts failures on a child (intended for testing and debugging).
This commit adds a test `test_child_supervision` to cover behavior of
child supervision and its new behaviors.
This change allows backward compatibility: If the parent does not
support child supervision, it ignores the new TLV in the MLE messages
and the child would fall back to periodically exchanging MLE Child
Update Request with parent. If the child does not support supervision
and/or does not indicate its desired child supervision interval, the
parent will fall back to use the configured default interval.
This commit adds new public OT APIs in `border_routing.h` to get the
current state of `RoutingManager` and to get the current favored
on-link prefix.
This commit also updates CLI `br` commands:
- It moves the CLI `br` implementation into own `cli_br` module.
- It adds `br state` to get the current state
- It changes `br omrprefix`, `br onlinkprefix`, and `br nat64prefix`
to output both local and favored prefixes when no additional arg
is provided and allow the use of `local` or `favored` extra arg to
specify the type.
- It updates the documentation of `br` related commands in the source
code and also adding `cli/README_BR.md`.
According to Thread 1.3.0 Section 4.7.1.3, router synchronization
after reset requires the multicast link request message to be
retransmitted until a response is received, or the maximum
transmission limit has been reached. If the router was a leader or had
more than 5 children prior to reset, it MUST be retransmitted as a
critical message. Each multicast retransmission of an MLE Message on a
TL1 or TL2 Link must be delayed by MLE_MULTICAST_RETRANSMISSION_DELAY
multiplied by a random value between 0.9 and 1.1 with a resolution of
at least 1 ms.
This commit implements the above requirement. With this requirement,
in the cases when a router is reset and there is no other router to
respond to the link request then it takes longer time for the router
to join thread network. Thus some test cases are modified to allow
longer router sync time in such cases.
he power calibration is supported by OT, this commit adds diag
commands that are used to measure the mapping between the actual power
and raw power settings, show the platform used power settings table.
1. Add "diag powersettings" to show the platform currently used power
settings table.
2. Add "diag rawpowersetting" to make the platform to use the given
raw power settings to transmit frames.
3. Add "diag cw" to transmit the continuous carrier wave.
This commit adds support for TLS in the TCP CLI tool, along with a
test of TLS functionality.
The main purpose of this is to provide an example of how to use
mbedTLS with TCPlp to run TLS. I felt it is important to have an
example because I expect that many applications that use TCP,
particularly those in which a Thread device exchanges data with a
device outside the Thread mesh, will need to run TLS over TCP for
security reasons.
A secondary benefit is to add TCP functionality to the TCP CLI
tool. Additionally, by having the example code be part of a "real"
application (the CLI tool), there is less risk of the code going stale
as OpenThread evolves.
I added an "expects" test for the TLS functionality in the CLI tool. I
also ran the code on two Nordic NRF52840-DK boards to make sure it
works.
The performance impact of TLS appears to be small. When using TCP
without TLS, I am able to achieve ~80 kb/s goodput between two
NRF52840-DK boards. With TLS in the same setup, I am able to achieve
~70-75 kb/s goodput.
This commit add `discover reqcallback {enable/disable}` CLI command
which registers callback to output whenever device gets a "MLE
Discovery Request". This command allows the callback to be explicitly
set when needed and avoid having it be enabled by default (since the
extra output from this callback can be treated as unexpected result by
tests that parse the CLI output).
If an infrastructure-provided NAT64 prefix is present, we should
bypass the NAT64 translator to let the border router forward the
packet to the infra NAT64 service.
The actual output power of the Thread device may be determined by both
the Thread radio chip and the FEM. Consider the output power error of
the Thread radio chip and the gain error of the FEM, the actual output
power is inconsistent with the expected output power. To guarantee
that the actual output power is accurate and meet the regulatory
requirements, the output power should be calibrated in the factory if
the output power is not accurate.
This commit contains the following changes:
- Adds a power calibration implementation
- Adds a config file to configure the target power for different
countries
- Adds a tool for the factory to persist the power calibration data
This commit updates behavior when device mode gets changed
so to re-attach on switching between MTD/FTD modes and also on
switching from rx-on to sleepy (rx-off) mode (when attached as a
child).
This commit also updates `test-027-child-mode-change.py` to match
the new behavior.
This commit increases the wait time in `test_single_border_router`
after re-enabling `ether` link. It also changes the order of pings
in the test (first ping from host to Thread router and the opposite
direction).
This commit add a new feature in `Srp::Client` to allow user to
specify the lease and/or key lease intervals explicitly per service.
The lease intervals in a service can be left unspecified(set to zero)
in which case the default lease intervals will be used.
In an SRP Update message, the lease info is included in additional
section in an Update Lease Option record. Therefore the lease values
are applicable to the entire message and all its records. If we have
services with different lease intervals, they need to be registered
in separate messages. This commit updates `Srp::Client` to implement
such a mechanism. When preparing an SRP message, we first determine
the lease and key lease intervals and ensure the services using
matching intervals are included in the message.
This commit also updates and simplifies the "single service mode"
functionality to use the newly added mechanism for tracking which
services are included in the message.
This commit adds `test_srp_register_services_diff_lease` which covers
the behavior of the newly added mechanisms.
This commit updates CLI `SrpServer`, `CoapSecure`, `UdpExample`, and
`TcpExample` to use the template `Process<Cmd("cmd")>` model. This
helps make them similar to other CLI modules.
This commit fixes the "single service mode" behavior to handle
if there are many simultaneous service removes. It also updates the
test to cover this situation.
This commit updates CLI `linkmetrics query` command to allow it
to be used in blocking mode (wait for response to query). This
is then used in different tests to validate the `LinkMetrics`
module behavior. In particular, `v1_2_test_single_probe` and
`v1_2_LowPower_7_2_01_ForwardTrackingSeries` are updated to
validate that the received query report message is correctly
parsed.
This commit imports `Crypto` module only when it's used.
This helps thread-cert tests that do not use message factory to run
without having to install `Crypto` module.
According to the Spec, egress packets from LLA should not be
forwarded. Linux kernel doesn't automatically block such forwarding
so that we need to check this before adding the MFC entry.
According to Thread Spec, PBBR should not forward a multicast packet
from Thread interface to Backbone interface when the source address is
Mesh-Local.
This commit fetches the NAT64 prefix on infrastructure interface and
advertise it to Network Data at medium preference.
- Use `getaddrinfo_a()` function to asynchronously lookup the ipv6
address of the special domain `ipv4only.arpa`. The infrastructure
NAT64 prefix is extracted from the domain answer.
- `mInfraIfNat64PrefixStaleTimer` is scheduled to monitor the presence
and change of infrastructure NAT64 prefix.
- `EvaluateNat64Prefix` evaluates whether to advertise the
infrastructure prefix or the local ULA prefix or neither. When there
is a new infrastructure prefix, it will withdraw the legacy one and
add the new one. When the infrastructure prefix no longer exists, it
will withdraw the legacy one and add the local ULA prefix. When the
infrastructure prefix presents again, it will add the infrastructure
prefix and withdraw the local ULA prefix.
New tests are added to test the scenarios when infrastructure NAT64
prefix exists. `DNS64` on OTBR is turned on to enable `bind9` with
NAT64 prefix on infrastructure interface for these tests. `bind9` is
explicitly turned off when testing local ULA prefix. Since bind9 is
conflict with other components like dnssd, all nat64 tests are moved
under /nat64 directory and configured separately.
The case that two or more BRs have same infrastructure NAT64 prefix is
not covered by this commit and will be followed up later.
This commit updates how unspecified CSL channel is conveyed in MLE
messages. Special value of zero in CSL Channel TLV is used to
indicate that the CSL channel is unspecified. The exclusion of the
TLV keeps the CSL channel as before (no change to the previously
set CSL channel).
This commit updates `test_mle_msg_key_seq_jump` to increase the wait
time after key index change for MLE advertisement transmissions. The
MLE advertisement uses trickle timer with max interval of 32 seconds.
Based on this the max interval between two consecutive advertisement
transmissions can be 1.5 times the trickle timer max interval or 48
seconds. The test uses 52 sec as wait time which includes a 4 sec
additional guard time to account for any action and/or message
exchanges after rx of an advertisement. This change should help
address the occasional failures of this test.
Thread BR may advertise IPv6 GUA rather than LLA. For example, Avahi
stops publishing LLA when any GUA is found on the network interface.
This commit enhances mdns_query to find border agents with
non-link-local addresses.
This commit changes the NAT64 CI tests to be ran as an independent
job. A new /nat64 folder is added and it would make it easier to
configure new NAT64 tests in the future.
This commit updates the MLE attach process so that in the first attach
cycle device tries a total of six MLE Parent Requests, the first two
to routers only followed by four to routers and REEDs. For example,
the six Parent Request message will be used before device can decide
to act the leader. An MTD in the next attach attempt (if cannot find a
parent in first attempt cycle), will go to the model of two Parent
Requests (first to routers, then to routers/REEDs).
This change impacts the time it takes for a device to start as leader
(due to increased number of Parent Request and wait time). This commit
updates different test scripts to address the change in the wait
time. It adds a new `config.LEADER_STARTUP_DELAY` constants which is
used for wait time for leader to start.
