2019-03-28RDMA/core: Introduce ib_core_device to hold deviceParav Pandit2-17/+36
In order to support sysfs entries in multiple net namespaces for a rdma device, introduce a ib_core_device whose scope is limited to hold core device and per port sysfs related entries. This is preparation patch so that multiple ib_core_devices in each net namespace can be created in subsequent patch who all can share ib_device. (a) Move sysfs specific fields to ib_core_device. (b) Make sysfs and device life cycle related routines to work on ib_core_device. (c) Introduce and use rdma_init_coredev() helper to initialize coredev fields.

2019-03-28RDMA/rdmavt: Use correct sizing on buffers holding page DMA addressesShiraz Saleem1-1/+1
The buffer that holds the page DMA addresses is sized off umem->nmap. This can potentially cause out of bound accesses on the PBL array when iterating the umem DMA-mapped SGL. This is because if umem pages are combined, umem->nmap can be much lower than the number of system pages in umem. Use ib_umem_num_pages() to size this buffer.

2019-03-28RDMA/bnxt_re: Use correct sizing on buffers holding page DMA addressesSelvin Xavier7-53/+67
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.

The variable len is not being inintialized and the uninitialized value is being returned. However, this return path is never reached because the default case in the switch statement returns -ENOSYS. Clean up the code by replacing the return -ENOSYS with a break for the default case and returning -ENOSYS at the end of the function. This allows len to be removed. Also remove redundant break that follows a return statement.
