Top 4 Features
Zero Execution Interruption
Stopping the kernel is problematic for low-latency applications such as transactional databases. Live Patching uses the familiar ftrace-based approach to perform the updates. This happens without ever stopping the kernel, not even for a moment.
Minimalist Design
Live Patching is easy to add to your existing code base. It leverages the technologies and ideas already present in the upstream Linux kernel: ftrace and its mcount-based space allocation in function prologues.
Secure
The Live Patching kernel complies with advanced security technologies such as UEFI secure boot, which require kernel modules to be signed by an approved signing key.
Familiar Deployment Methods
Like all maintenance updates, the patches delivered by Live Patching are delivered as signed RPMs. Introducing the solution into your established administrative process is simple because you can reuse existing deployment methods, including YaST, zypper, and SUSE Multi-Linux Manager.
