RDMA/bnxt_re: Honor vlan_id in GID entry comparison A GID entry consists of GID, vlan, netdev and smac. Extend GID duplicate check comparisons to consider vlan_id as well to support IPv6 VLAN based link local addresses. Introduce a new structure (bnxt_qplib_gid_info) to hold gid and vlan_id information. The issue is discussed in the following thread https://lore.kernel.org/r/AM0PR05MB4866CFEDCDF3CDA1D7D18AA5D1F20@AM0PR05MB4866.eurprd05.prod.outlook.com Fixes: 823b23da7113 ("IB/core: Allow vlan link local address based RoCE GIDs") Cc: <stable@vger.kernel.org> # v5.2+ Link: https://lore.kernel.org/r/20190715091913.15726-1-selvin.xavier@broadcom.com Reported-by: Yi Zhang <yi.zhang@redhat.com> Co-developed-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Selvin Xavier <selvin.xavier@broadcom.com> Tested-by: Yi Zhang <yi.zhang@redhat.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>

RDMA/bnxt_re: Use correct sizing on buffers holding page DMA addresses umem->nmap is used while allocating internal buffer for storing page DMA addresses. This causes out of bounds array access while iterating the umem DMA-mapped SGL with umem page combining as umem->nmap can be less than number of system pages in umem. Use ib_umem_num_pages() instead of umem->nmap to size the page array. Add a new structure (bnxt_qplib_sg_info) to pass sglist, npages and nmap.

Merge branch 'k.o/wip/dl-for-rc' into k.o/wip/dl-for-next Due to bug fixes found by the syzkaller bot and taken into the for-rc branch after development for the 4.17 merge window had already started being taken into the for-next branch, there were fairly non-trivial merge issues that would need to be resolved between the for-rc branch and the for-next branch. This merge resolves those conflicts and provides a unified base upon which ongoing development for 4.17 can be based. Conflicts: drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524 (IB/mlx5: Fix cleanup order on unload) added to for-rc and commit b5ca15ad7e61 (IB/mlx5: Add proper representors support) add as part of the devel cycle both needed to modify the init/de-init functions used by mlx5. To support the new representors, the new functions added by the cleanup patch needed to be made non-static, and the init/de-init list added by the representors patch needed to be modified to match the init/de-init list changes made by the cleanup patch. Updates: drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function prototypes added by representors patch to reflect new function names as changed by cleanup patch drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init stage list to match new order from cleanup patch Signed-off-by: Doug Ledford <dledford@redhat.com>

Workaround to handle the problem where the HW fast path engine continues to access DMA memory in retranmission mode even after the WQE has already been completed.
