红帽全球峰会8.9. Updating kernel patch modules
The kernel patch modules are delivered and applied through RPM packages. The process of updating a cumulative kernel patch module is similar to updating any other RPM package.
Prerequisites
- The system is subscribed to the live patching stream, as described in Subscribing the currently installed kernels to the live patching stream.
Procedure
Update to a new cumulative version for the current kernel:
# dnf update kpatchThis command automatically installs and applies any updates that are available for the currently running kernel. Including any future released cumulative live patches.
Alternatively, update all installed kernel patch modules:
# dnf update kpatch
注意
When the system reboots into the same kernel, the kernel is automatically live patched again by the kpatch.service systemd service.
