In xfs_dir2_data_use_free, we examine on-disk metadata and ASSERT if it doesn't make sense. Since a carefully crafted fuzzed image can cause the kernel to crash after blowing a bunch of assertions, let's move those checks into a validator function and rig everything up to return EFSCORRUPTED to userspace. Found by lastbit fuzzing ltail.bestcount via xfs/391. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com> |

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.
