For example, the kernel version we are working with is 3. A kpatch with a level is the initial empty patch, used to subscribe the system to future live updates for this kernel version. A kpatch package with a version or higher contains live kernel patches.

The kpatch patches are cumulative, so in general, we want to use the latest one for the kernel version that is being live patched. To see the kpatch updates available in the Satellite environment,from the Satellite web interface, go to the Content menu, and select Packages. Next, filter for kpatch-patch , which will show a list of available kpatch live kernel update patches.

From the previous screenshot, we can see that there are kpatch updates available for three different kernel versions: 3. In this post, we are working with kernel 3. For these lines, we can see that there are three kpatch levels available: , , and Because kpatchs are cumulative, we will go with the latest kpatch version available for this kernel version, which is version We are now ready to install the live kernel patch on our Satellite clients running the 3.

To start the process, go to the Monitor menu, select Jobs , and click the blue Run Job button in the upper right corner. Additionally, select the previously created search bookmark named hosts with kernel 3. We can verify the live kernel patches were successfully loaded by running another remote execution job, which will check the status of the kpatch list command.

To check this, go back to the Monitor menu, select Jobs , and click the blue Run Job button in the upper right corner. We will again select the previously created search bookmark named hosts with kernel 3. The easiest way to find the text to use in the command is to login to one of the client servers that was patched and run kpatch list to see a list of enabled kpatchs.

If this remote execution job fails on any hosts, investigate further to determine the issue. This is where tracer comes in to help identify which processes need to be restarted after installing package updates. As a reminder, tracer, in Satellite versions 6.

Please review my previous post covering an Introduction to the Tracer feature in Satellite , as it covers how to get tracer setup in the environment. Having tracer setup in the environment is necessary before proceeding with further steps in this post. This command will install the security related updates and exclude the kernel related packages, since we previously live patched the kernel. To check this, go to the Hosts menu, and click on Content Hosts. Next, click on a host that was updated and go to the Traces tab, which shows that the ksmtuned daemon needs to be restarted for the updated packages to take effect:.

Depending on the environment, we might need to see which processes need to be restarted by checking each content host individually, selecting the processes to be restarted, and clicking the Restart Selected button.
