- What I did
Added support for secure upgrade.
- How I did it
During sonic_installer install, added secure upgrade image verification.
HLD can be found in the following PR: sonic-net/SONiC#1024
- Why I did it
Feature is used to allow image was not modified since built from vendor. During installation, image can be verified with a signature attached to it.
- How I did it
Feature includes image signing during build (in sonic buildimage repo) and verification during image install (in sonic-utilities).
- How to verify it
In order for image verification - image must be signed - need to provide signing key and certificate (paths in SECURE_UPGRADE_DEV_SIGNING_KEY and SECURE_UPGRADE_DEV_SIGNING_CERT in rules/config) during build , and during image install, need to enable secure boot flag in bios, and signing_certificate should be available in bios.
- Feature dependencies
In order for this feature to work smoothly, need to have secure boot feature implemented as well.
The Secure boot feature will be merged in the near future.
