commit 4b14752ec4e0d87126e636384cf37c8dd9df157c upstream. We can't do anything reasonable in security_bounded_transition() if we don't have a policy loaded, and in fact we could run into problems with some of the code inside expecting a policy. Fix these problems like we do many others in security/selinux/ss/services.c by checking to see if the policy is loaded (ss_initialized) and returning quickly if it isn't.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
