The size of fields within a structure is needed in a few places in the kernel already, and will be needed for the usercopy whitelisting when declaring whitelist regions within structures. This creates a dedicated macro and redefines offsetofend() to use it. Existing usage, ignoring the 1200+ lustre assert uses: $ git grep -E 'sizeof\(\(\((struct )?[a-zA-Z_]+ \*\)0\)->' | \ grep -v staging/lustre | wc -l 65 Signed-off-by: Kees Cook <keescook@chromium.org>
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.
