[ Upstream commit a72f64261359b7451f8478f2a2bf357b4e6c757f ] In the write to the output_fd in the error condition of record_saved_cmdline(), we are writing 8 bytes from a memory location on the stack that contains a primitive that is only 4 bytes in size. Change the primitive to 8 bytes in size to match the size of the write in order to avoid reading unknown memory from the stack.

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.
