Maintenance Updates

Wind River Linux releases align with Yocto Project releases

Annual Wind River Linux releases align with Yocto Project community releases.

The Wind River Linux release model follows a one-year release cadence, i.e., one release version every year. In effect, this means that roughly every 12 months Wind River introduces a new release with a new kernel for the Wind River Linux base platform and other architectural changes deriving from this, in alignment with Yocto Project community releases.

Rolling Cumulative Patch Layers

Software patches and minor updates to current releases, with active maintenance, are delivered via rolling cumulative patch layers (RCPLs). These RCPLs are provided on an ongoing basis according to a predictable schedule and do not trigger any major kernel, tool chain, or user space packages revisions (unless a critical issue requires specific action).

RCPLs are accessible using the Wind River electronic software delivery mechanism, and information about each RCPL, including technical content, is available on the Wind River Support Network. Certain product enhancements and new board support packages (BSPs) may also be included in these monthly patches, and RCPLs are mandatory installations. All RCPLs go through the Wind River standard product validation tests.

Example of RCPL Content and Trend

Wind River provides cumulative updates to CVEs

Wind River provides cumulative updates to CVEs through a support and maintenance agreement.

The value of maintenance includes delivery of fixes for defects (broken functionality) and Common Vulnerabilities and Exposures (CVEs). For example, for the first five years of the Wind River Linux LTS18 lifecycle, the value of each RCPL delivery increased incrementally.

  • In the first couple of years, with the new technology adoption and deployment, the trend was toward higher defect fixes.
  • As the code stabilized from a functionality perspective and the number of defects decreased, trending toward zero, the overall number of CVEs was slowly increasing before stabilizing and having a linear decrease trend.

The cumulative updates are available to customers with a valid, active standard support and maintenance agreement and can be downloaded throughout the product lifecycle. RCPLs are available on the Wind River Support Network.

The latest RCPL can be downloaded from the “Downloads” section of its respective Linux product on the Wind River Support Network. Whenever a new RCPL is released, the previous one goes into the Legacy section.
