Matter Linux/Mac All Clusters Example

Compiling all-clusters-app for testing on Linux and Mac

To compile all-clusters-app on Intel Mac, using the bootstrap-provided clang, run:

$ ./scripts/run_in_build_env.sh "./scripts/build/build_examples.py --target darwin-x64-all-clusters-no-ble-asan-clang build"

at the top level of the Matter tree.

To compile all-clusters-app on Intel Mac, using the system clang, run:

$ ./scripts/run_in_build_env.sh "./scripts/build/build_examples.py --target darwin-x64-all-clusters-no-ble-asan build"

To compile on an Arm Mac, which can only be done using the system clang, run:

$ ./scripts/run_in_build_env.sh "./scripts/build/build_examples.py --target darwin-arm64-all-clusters-no-ble-asan build"

Similarly, to compile on Linux x86-64 run:

$ ./scripts/run_in_build_env.sh "./scripts/build/build_examples.py --target linux-x64-all-clusters-no-ble-asan-clang build"

And to compile on Linux ARM run:

$ ./scripts/run_in_build_env.sh "./scripts/build/build_examples.py --target linux-arm64-all-clusters-no-ble-asan-clang build"

Fuzzing integration

This example also supports compilation with libfuzzer enabled. This should be used when trying to fuzz-test the Matter SDK.

Compiling with fuzzing enabled

To compile with libfuzzer enabled on Mac, run:

$ ./scripts/run_in_build_env.sh "./scripts/build/build_examples.py --target darwin-x64-all-clusters-no-ble-asan-libfuzzer-clang build"

at the top level of the Matter tree.

Similarly, to compile on Linux run:

$ ./scripts/run_in_build_env.sh "./scripts/build/build_examples.py --target linux-x64-all-clusters-no-ble-asan-libfuzzer-clang build"

Running libfuzzer-enabled binaries

Initial run

To run the resulting binary with no particular inputs do:

$ ./out/darwin-x64-all-clusters-no-ble-asan-libfuzzer-clang/chip-all-clusters-app-fuzzing

or

$ ./out/linux-x64-all-clusters-no-ble-asan-libfuzzer-clang/chip-all-clusters-app-fuzzing

If this crashes, it will output the input that caused the crash in a variety of formats, looking something like this:

0xe,0x0,0xf1,0xb1,0xf1,0xf1,0xf1,0xf1,0xed,0x73,0x7,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0xc1,0x0,0x0,0x0,0x0,0x0,0x5c,0xf3,0x25,0x0,0x0,0x0,0x0,0x0,
\016\000\361\261\361\361\361\361\355s\007\000\000\000\000\000\000\000\301\000\000\000\000\000\\\363%\000\000\000\000\000
artifact_prefix='./'; Test unit written to ./crash-c9fd2434ccf4a33a7f49765dcc519e1fd529a8e5
Base64: DgDxsfHx8fHtcwcAAAAAAAAAwQAAAAAAXPMlAAAAAAA=

Note that this creates a file holding the input that caused the crash.

Run with a fixed input

To run the binary with a specific input, place the input bytes in a file (which a crashing run of the fuzzer does automatically). If $(INPUT_FILE) is the name of that file, then run:

$ ./out/darwin-x64-all-clusters-no-ble-asan-libfuzzer-clang/chip-all-clusters-app-fuzzing $(INPUT_FILE)

or

$ ./out/linux-x64-all-clusters-no-ble-asan-libfuzzer-clang/chip-all-clusters-app-fuzzing $(INPUT_FILE)

Additional execution options.

The binary can be run with -help=1 to see more available options.

Running with ASAN_OPTIONS="handle_abort=2" set in the environment may produce nicer stack traces.

Trigger event using all-cluster-app event named pipe

You can send a command to all-cluster-app to trigger specific event via all-cluster-app event named pipe /tmp/chip_all_clusters_fifo-.

Trigger SoftwareFault events

  1. Generate event SoftwareFault when a software fault takes place on the Node.
$ echo '{"Name":"SoftwareFault"}' > /tmp/chip_all_clusters_fifo-<PID>

Trigger HardwareFault events

  1. Generate event HardwareFaultChange to indicate a change in the set of hardware faults currently detected by the Node.
$ echo '{"Name":"HardwareFaultChange"}' > /tmp/chip_all_clusters_fifo-<PID>
  1. Generate event RadioFaultChange to indicate a change in the set of radio faults currently detected by the Node.
$ echo '{"Name":"RadioFaultChange"}' > /tmp/chip_all_clusters_fifo-<PID>
  1. Generate event NetworkFaultChange to indicate a change in the set of network faults currently detected by the Node.
$ echo '{"Name":"NetworkFaultChange"}' > /tmp/chip_all_clusters_fifo-<PID>
  1. Generate event BootReason to indicate the reason that caused the device to start-up, from the following set of BootReasons.

  • PowerOnReboot The Node has booted as the result of physical interaction with the device resulting in a reboot.

  • BrownOutReset The Node has rebooted as the result of a brown-out of the Node’s power supply.

  • SoftwareWatchdogReset The Node has rebooted as the result of a software watchdog timer.

  • HardwareWatchdogReset The Node has rebooted as the result of a hardware watchdog timer.

  • SoftwareUpdateCompleted The Node has rebooted as the result of a completed software update.

  • SoftwareReset The Node has rebooted as the result of a software initiated reboot.

$ echo '{"Name":"<BootReason>"}' > /tmp/chip_all_clusters_fifo-<PID>

Trigger Switch events

  1. Generate event SwitchLatched, when the latching switch is moved to a new position.
$ echo '{"Name":"SwitchLatched","NewPosition":3}' > /tmp/chip_all_clusters_fifo-<PID>
  1. Generate event InitialPress, when the momentary switch starts to be pressed.
$ echo '{"Name":"InitialPress","NewPosition":3}' > /tmp/chip_all_clusters_fifo-<PID>
  1. Generate event LongPress, when the momentary switch has been pressed for a “long” time.
$ echo '{"Name":"LongPress","NewPosition":3}' > /tmp/chip_all_clusters_fifo-<PID>
  1. Generate event ShortRelease, when the momentary switch has been released.
$ echo '{"Name":"ShortRelease","PreviousPosition":3}' > /tmp/chip_all_clusters_fifo-<PID>
  1. Generate event LongRelease when the momentary switch has been released and after having been pressed for a long time.
$ echo '{"Name":"LongRelease","PreviousPosition":3}' > /tmp/chip_all_clusters_fifo-<PID>
  1. Generate event MultiPressOngoing to indicate how many times the momentary switch has been pressed in a multi-press sequence, during that sequence.
$ echo '{"Name":"MultiPressOngoing","NewPosition":3,"CurrentNumberOfPressesCounted":4}' > /tmp/chip_all_clusters_fifo-<PID>
  1. Generate event MultiPressComplete to indicate how many times the momentary switch has been pressed in a multi-press sequence, after it has been detected that the sequence has ended.
$ echo '{"Name":"MultiPressComplete","PreviousPosition":3,"TotalNumberOfPressesCounted":2}' > /tmp/chip_all_clusters_fifo-<PID>
