Add the rcu synchronization mechanism for accessing smk_ipv6_port_list in smack IPv6 hooks. Access to the port list is vulnerable to a race condition issue,it does not apply proper synchronization methods while working on critical section. It is possible that when one thread is reading the list, at the same time another thread is modifying the same port list, which can cause the major problems. To ensure proper synchronization between two threads, rcu mechanism has been applied while accessing and modifying the port list. RCU will also not affect the performance, as there are more accesses than modification where RCU is most effective synchronization mechanism.

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.
