The 10th was yesterday (when you said:
"We are going to add support for this kernel today. Please try to apply KernelCare patches sometime later today.";)

Care to make an update on the release date progress?

and now we have 2.6.32-754.2.1.el6.x86_64

when will patches or new kernelcare be available for this one?

The system kernel is at version “2.6.32-754.el6”, but an update is available: 2.6.32-754.2.1.el6.x86_64
You must take one of the following actions to ensure the system is up-to-date:•Wait a few days for KernelCare to publish a kernel patch.
Update the system (run “yum -y update” on the command line), and reboot the system.

According to https://patches.kernelcare.com/ this kernel version is already supported. If KernelCare reports it as not supported, please open a ticket and we will resolve it: https://cloudlinux.zendesk.com/hc/requests/new

Indeed, kernel is supported only on RHEL and Oracle Linux. We are going to add support for this kernel on CentOS tomorrow.

Is kcare even working or should we remove it? We have had “unknown kernel” notices for over a month, the extra patch set is invalid, and now we are getting these notices during autoupdate:

sysctl: cannot stat /proc/sys/fs/enforce_symlinksifowner: No such file or directory
sysctl: cannot stat /proc/sys/fs/symlinkown_gid: No such file or directory

CentOS 7, 3.10.0-862.9.1.el7.x86_64

CPanel recommended we use this, but I don’t trust or know enough to know if its actually doing anything for us.

after receiving the reply above, I reattempted the automated process of /usr/bin/kcarectl --auto-update --gradual-rollout=auto and can confirm it is now updating without errors. Our maintenance scripts run in the a.m. I just assumed it was still the same since I've been getting "unknown..." for the last few weeks. The extra package type error is also gone.

My question is...even though the kernel is unknown, or the extra package type isn't recognize (I assume for the current kernel of the system), kcare is still doing something, right? As a novice, it just felt like after weeks of the unknown kernel message that we weren't being "protected". After my post I was reading that other things are going on that make the kcare useful, even during interim events where new kernels surpass the patch level of kcare (?that's more of a question than a statement).

KernelCare can only apply patches to supported kernels. If kernel is not supported, no patches are applied which means no extra protection is provided. But since new kernels usually do not have known vulnerabilities and we constantly adding support for new kernels, there should be no problems with it. I mean if kernel is new and not yet supported, it is safe enough to run it because it is new and already has all the latest security fixes.

KernelCare has not updated my Centos System now for over 2 weeks...

I receive the following;


Unknown Kernel (CentOS 2.6.32-754.3.5.el6.x86_64)


When will this version be supported?

CloudLinux 6.10

Been getting these in the past 24 hours:

Cron <root> /usr/bin/kcarectl --auto-update --gradual-rollout=auto

Unknown Kernel (CloudLinux Server 2.6.32-954.3.5.lve1.4.58.el6.x86_64)

I have my paid CloudLinux licenses through cPanel and my paid KernelCare licenses right through CL/KC here.

Is this a matter of waiting for a patch? Or is this more significant?

Thank you,
Dave
