Jason Gunthorpe says: ==================== Upon review it turns out there are some long standing problems in BAR mapping area: * BAR pages intended for read-only can be switched to writable via mprotect. * Missing use of rdma_user_mmap_io for the mlx5 clock BAR page. * Disassociate causes SIGBUS when touching the pages. * CPU pages are being mapped through to the process via remap_pfn_range instead of the more appropriate vm_insert_page, causing weird behaviors during disassociation. This series adds the missing VM_* flag manipulation, adds faulting a zero page for disassociation and revises the CPU page mappings to use vm_insert_page. ==================== For dependencies this branch is based on for-rc from git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git * branch 'rdma_mmap': RDMA: Remove rdma_user_mmap_page RDMA/mlx5: Use get_zeroed_page() for clock_info RDMA/ucontext: Fix regression with disassociate RDMA/mlx5: Use rdma_user_map_io for mapping BAR pages RDMA/mlx5: Do not allow the user to write to the clock page Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
