“Elivepatch” addresses the limitations and shortcomings of the current distributed live patching services as follows:
• 3rd-party trust: Trust on a third-party service can be eliminated by deploying Elivepatch in-house.
• Custom kernel configurations: Live patches can be created for different kernel versions and configurations by varying the parameters to Elivepatch.
• Modified kernels: Support is extended to locally modified kernels (e.g. out-of-tree patch sets) by sending the server a list of patches that should be applied before the live patch creation process starts.
• Client-generated patches: In Elivepatch, clients specify the live patches to be created whereas current systems only support vendor-generated patches.
• Security auditing: Elivepatch is completely open source and thus fully auditable.
