2023-12-07RDMA/hns: Add a max length of gid tableJunxian Huang
IB-core and rdma-core restrict the sgid_index specified by users, which is uint8_t/u8 data type, to only be within the range of 0-255, so it's meaningless to support excessively large gid_table_len. On the other hand, ib-core creates as many sysfs gid files as gid_table_len, most of which are not only useless because of the reason above, but also greatly increase the traversal time of the sysfs gid files for applications. This patch limits the maximum length of gid table to 256.

2023-11-13RDMA/siw: Use crypto_shash_digest() in siw_qp_prepare_tx()Eric Biggers
Simplify siw_qp_prepare_tx() by using crypto_shash_digest() instead of an init+update+final sequence. This should also improve performance.

2023-11-13RDMA/bnxt_re: Remove roundup_pow_of_two depth for all hardware queue resourcesChandramohan Akula
Rounding up the queue depth to power of two is not a hardware requirement. In order to optimize the per connection memory usage, removing drivers implementation which round up to the queue depths to the power of 2. Implements a mask to maintain backward compatibility with older library.

2023-11-13RDMA/bnxt_re: Refactor the queue index updateChandramohan Akula
The queue index wrap around logic is based on power of 2 size depth. All queues are created with power of 2 depth. This increases the memory usage by the driver. This change is required for the next patches that avoids the power of 2 depth requirement for each of the queues. Update the function that increments producer index and consumer index during wrap around. Also, changes the index handling across multiple functions.

2023-11-13RDMA/hfi1: Copy userspace arrays safelyPhilipp Stanner
Currently, memdup_user() is utilized at two positions to copy userspace arrays. This is done without overflow checks. Use the new wrapper memdup_array_user() to copy the arrays more safely.

2023-11-13RDMA/siw: Use ib_umem_get() to pin user pagesBernard Metzler
Abandon siw private code to pin user pages during user memory registration, but use ib_umem_get() instead. This will help maintaining the driver in case of changes to the memory subsystem.
