It looks like I want four security operations/hooks for cachefiles: FYI, I added the following vectors: # kernel services that need to override task security class kernel_service { use_as_override create_files_as } The first allows: avc_has_perm(daemon_tsec->sid, nominated_sid, SECCLASS_KERNEL_SERVICE, KERNEL_SERVICE__USE_AS_OVERRIDE, NULL); And the second something like: avc_has_perm(tsec->sid, inode->sid, SECCLASS_KERNEL_SERVICE, KERNEL_SERVICE__CREATE_FILES_AS, NULL); Rather than specifically dedicating them to the cache, I made them general.
