KCM and strparser hasn't been reviewed extensively during their upstreaming phase and were accepted despite criticism of the architecture. Doing socket(AF_KCM) autoloads the module and exposes it for ordinary users. Please blacklist this module from autoloading or (even better) remove it from the kernel config completely.
The option had been turned on when it came in because it was available as a module. There was no strong use case so I turned it off on all branches. It will be staying off until we hear that the architecture problems have been addressed.
