  • Add license and let it could automatically generate

    Add license and let it could automatically generate

    1. update the dependency licenses
    2. integrate with skywalking-eyes, let it could generate the license automatically.
    3. Add to the CI, so it can check the dependency license in each PR.

    @kezhenxu94 Please help to check the license generate code, there have some duplicated codes with eyes, not all of them. Maybe we could let the eyes generate it?

  • Introduce the BTFhub module

    Introduce the BTFhub module

    Follow Blog: https://kinvolk.io/blog/2022/03/btfgen-one-step-closer-to-truly-portable-ebpf-programs/ I see it could help users running the eBPF program with CO-RE on the old kernel(without recompile kernel), It's pretty cool. So we could add it.

  • Fix the profiling data finished time is greater than task duration

    Fix the profiling data finished time is greater than task duration

    The rover uses the scratch mechanism to get data from the eBPF runner with intervals, but the profiling task duration is fixed. So the end time of the profiling data could be out of the profiling task duration. When the duration of the profiling task is the same as the time that OAP can analyze, it may cause the failure to analyze.

  • Fix profiling issue and add logs

    Fix profiling issue and add logs

    1. Add logs in the profiling module to help understand the profiling status.
    2. Fix the problem that docker based processes cannot be detected.
    3. Fix can't do ON_CPU profiling twice error, It's a bug in the current milestone, so don't need to add it to the change log.
    4. Add the download links to the [README.md].

  • Update to using frequency mode to `ON_CPU` Profiling.

    Update to using frequency mode to `ON_CPU` Profiling.

    Follow https://man7.org/linux/man-pages/man2/perf_event_open.2.html The description of the sample_period, sample_freq, we need to change the ON_CPU to frequency sampling mode.

  • Support OFF CPU Profiling

    Support OFF CPU Profiling

    We also need to wait the CLI, OAP support, and automatic generate the BTF, after these finished, I will add the E2E testing for the OFF_CPU Profiling.

  • Fix process id analyze error when same process bind to multiple entities

    Fix process id analyze error when same process bind to multiple entities

    When a process has multiple entities, such as in the Kubernetes detector, the process may belong to MESH and K8S_SERVICE. Currently, the rover only matches the first process ID to process. When profiling the process, it will not match the process.
