[ Upstream commit 015c44d7bff3f44d569716117becd570c179ca32 ] Since the recent introduction supporting the SM3 and SM4 hash algos for IPsec, the kernel produces invalid pfkey acquire messages, when these encryption modules are disabled. This happens because the availability of the algos wasn't checked in all necessary functions. This patch adds these checks.

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.
