generic_permission() presently checks CAP_DAC_OVERRIDE prior to CAP_DAC_READ_SEARCH. This can cause misleading audit messages when using a LSM such as SELinux or AppArmor, since CAP_DAC_OVERRIDE may not be required for the operation. Flip the order of the tests so that CAP_DAC_OVERRIDE is only checked when required for the operation.

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.
