Environment
Release : All
Component : CA ControlMinder CA PIM CA PAMSC
Cause
The OS vender reports these messages to document the loading of any third party module into the kernel
Resolution
The feature that reports the message is intended to help identify conditions which may make it to properly troubleshoot a kernel problem. While this message may be displayed for a variety of reasons the case of this product seos kernel drivers as long as you are using the supported build of our endpoint software on this machine these messages can be ignored. For a specific definition
loading out-of-tree module taints kernel --- means the module is not included in the Linux Kernel source code
module license 'Proprietary' taints kernel --- means the module belongs to third party comapny and not supplied by the OS vendor
Disabling lock debugging due to kernel taint -- means that the built in OS supplied lock debuging is not turned on
module verification failed: signature and/or required key missing - tainting kernel --- means that this module version was not code signed with a PKI certificate or that certificate was not imported into the system.
These messages are usually simply informational except for the last one. If you enable Linux Secure Boot feature the module verification failed may indicate that the kernel will not load this module on boot. With the latest builds of our endpoint software we do ship the certificate which can be imported for verification.
