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> |
