Bring Your Own License (BYOL)

Release 4.0.0​

Release Date: Jan 14, 2025

New Features and Improvements​

  • I95-54266 AWS SSR image support for vTPM

On first boot of the SSR volume, the instance of the vTPM (if detected) is automatically initialized with the RSA encryption key pair. The BYOL image contains a script which is used to validate the vTPM operations based on the initialization.

Encrypt: /usr/libexec/128technology/t128_tpm_crypto encrypt -i secret.txt -o secret.txt.enc Decrypt: /usr/libexec/128technology/t128_tpm_crypto decrypt -i secret.txt.enc -o output.txt

important

SSR version 7.1.3-r2 or higher is required to leverage the vTPM capabilities in software.

  • WAN-4033, I95-60406 Enhancements to onboarding-config via cloud-init

New options were added to the onboarding-config (typically installed via cloud-init) to enable additional use cases. Some examples of new additions:

  • Support custom NTP server
  • Support static HTTPS Proxy for MIST connection
  • I95-62888 Support for HA sync and fabric links

Support for HA fabric and HA sync to establish a dual-node HA in public cloud.

Resolved Issues​

  • I95-62016 Sanitize sensitive information from logs and files on disk

    Resolution: Certain sensitive onboarding information is not properly scrubbed from files on disk and logs.

  • I95-63304 BYOL Template is not producing consistent interface ordering

    Resolution: Updated the udev and cloud-init rules to ensure a more strict ordering and naming of interfaces which matches the device map and SSR-ROLE tags more appropriately.

  • I95-62888 Interface tagging in Azure is not consistent

    Resolution: Some changes on the Azure side broke how the image manages interface tagging for role assignments. The Azure SDK has been updated to use managed identity APIs and more consistent parsing of the SSR-ROLE tags.
