Changes

Prepare v1.5.1 release

Reason

Added

  • #4287
    Document a caveat to the jailer docs when using the --parent-cgroup option,
    which results in it being ignored by the jailer. Refer to the jailer
    documentation
    for a workaround.

Changed

  • #4191:
    Refactored error propagation to avoid logging and printing an error on
    exits with a zero exit code. Now, on successful exit
    "Firecracker exited successfully" is logged.

Fixed

  • #4277: Fixed a
    bug that ignored the --show-log-origin option, preventing it from printing
    the source code file of the log messages.
  • #4179:
    Fixed a bug reporting a non-zero exit code on successful shutdown when
    starting Firecracker with --no-api.
  • #4271: Fixed
    a bug where Firecracker would log "RunWithApiError error: MicroVMStopped
    without an error: GenericError" when exiting after encountering an emulation
    error. It now correctly prints "RunWithApiError error: MicroVMStopped with an
    error: GenericError".
  • #4270:
    Fixed a bug introduced in Update logger #4047 that limited the --level option of logger
    to Pascal-cased values (e.g. accepting "Info", but not "info"). It now
    ignores case again.
  • #4295:
    Fixed a bug in the asynchronous virtio-block engine that rendered the device
    non-functional after a PATCH request was issued to Firecracker for updating
    the path to the host-side backing file of the device.

Yes, the release fixes only exist in this branch at the moment. Depending on this release experience, we will forward port them to the main branch.
