commit 19d7df69fdb2636856dc8919de72fc1bf8f79598 upstream. We don't have a compat layer for xfrm, so userspace and kernel structures have different sizes in this case. This results in a broken configuration, so refuse to configure socket policies when trying to insert from 32 bit userspace as we do it already with policies inserted via netlink.

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.
