When receiving a state message, function tipc_link_validate_msg() is called to validate its header portion. Then, its data portion is validated before it can be accessed correctly. However, current data sanity check is done after the message header is accessed to update some link variables. This commit fixes this issue by moving the data sanity check to the beginning of state message handling and right after the header sanity check.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
