treewide: use get_random_u32() when possible

2022-10-11T23:42:58Z

The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

IB: Set IOVA/LENGTH on IB_MR in core/uverbs layers

2022-09-22T09:46:39Z

Set 'iova' and 'length' on ib_mr in ib_uverbs and ib_core layers to let all drivers have the members filled. Also, this commit removes redundancy in the respective drivers. Previously, commit 04c0a5fcfcf65 ("IB/uverbs: Set IOVA on IB MR in uverbs layer") changed to set 'iova', but seems to have missed 'length' and the ib_core layer at that time.

RDMA: Split kernel-only global device caps from uverbs device caps

2022-04-06T18:02:13Z

Split out flags from ib_device::device_cap_flags that are only used internally to the kernel into kernel_cap_flags that is not part of the uapi. This limits the device_cap_flags to being the same bitmap that will be copied to userspace. This cleanly splits out the uverbs flags from the kernel flags to avoid confusion in the flags bitmap. Add some short comments describing which each of the kernel flags is connected to. Remove unused kernel flags.

RDMA/mlx4: Don't continue event handler after memory allocation failure

2022-02-01T14:12:26Z

The failure to allocate memory during MLX4_DEV_EVENT_PORT_MGMT_CHANGE event handler will cause skip the assignment logic, but ib_dispatch_event() will be called anyway. Fix it by calling to return instead of break after memory allocation failure.
