- 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.
