The check to know if an invalidation is needed (i.e. when the context changes) is done even if the context does not exist yet. This happens when first setting a key for ciphers and/or hmac operations. This commits adds a check in the _setkey functions to only check if an invalidation is needed when a context exists, as there is no need to perform this check otherwise.

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.
