RDMA/ocrdma: accept boolean value in ocrdma_dbgfs_ops_write()

2026-07-23T10:05:44+00:00

Since reset is actually controlled by the boolean flag rather than long, switch to 'kstrtobool_from_user()' and use the latter for an overall simplification of 'ocrdma_dbgfs_ops_write()'.

RDMA: Use ib_no_udata_io() in query_device callbacks

2026-07-20T13:00:40+00:00

The query_device callbacks that neither accept driver-specific input nor return a driver-specific response open-code the empty udata handling as ib_is_udata_in_empty() on entry and ib_respond_empty_udata() on exit. ib_no_udata_io() already combines both steps, so replace the entry check with it and simply return 0 on success. Unlike the create and destroy flows, query_device owns no uobject or HW resource - the extended path fills a stack ib_device_attr that the core discards on error - so clearing the empty response buffer on entry rather than on exit is a mechanical change with no functional difference.

RDMA: Remove redundant memset() from query_device callbacks

2026-07-14T06:53:14+00:00

The core always hands the driver's query_device() callback a zeroed ib_device_attr. There are only two callers of the op and both clear the structure before invoking it: setup_device() memsets &device->attrs, and ib_uverbs_ex_query_device() passes an on-stack structure initialized to {}. The open-coded memset(props, 0, sizeof(*props)) at the top of the driver callbacks is therefore redundant. Remove it from all drivers. Signed-off-by: Leon Romanovsky

RDMA: Update the query_device() op

2026-06-03T18:12:43+00:00

This op hasn't followed the normal pattern of passing NULL for udata when invoked by the kernel. Instead the kernel caller creates a dummy ib_udata on the stack and passes that in. It does not seem to currently be a bug, but this flow should be modernized to use the new API flow and in the process accept NULL as well. Only mlx4 uses an input request structure, have every other driver call ib_is_udata_in_empty() to enforce the lack of request structs. Use ib_respond_empty_udata() in every driver that does not use a response struct. Ensure a check for NULL udata before calling ib_respond_udata() in bnxt_re, efa, and mlx5. Make mlx4 safe to be called with NULL. Link: https://patch.msgid.link/r/2-v1-922fa8e828ba+f7-ib_udata_stack_jgg@nvidia.com Signed-off-by: Jason Gunthorpe

RDMA/umem: Rename ib_umem_get() to ib_umem_get_va()

2026-05-29T23:19:57+00:00

The new umem getter family being introduced in follow-up patches need a fitting name for the central all-source helper that resolves attributes, legacy fillers and a UHW VA fallback. Rename the existing VA-pinning helper ib_umem_get() to ib_umem_get_va() so the name is freed up. The new name is consistent with names of rest of the helpers that are about to be introduced.

RDMA: Replace memset with = {} pattern for ib_respond_udata()

2026-05-18T08:58:42+00:00

Most drivers do this already, but some open-code a memset. Switch all instances found. qedr_copy_qp_uresp() is already called with zeroed memory so that memset is redundant. Signed-off-by: Jason Gunthorpe Signed-off-by: Leon Romanovsky

RDMA: Convert drivers using sizeof() to ib_respond_udata()

2026-05-18T08:58:42+00:00

Convert the pattern: ib_copy_to_udata(udata, &resp, sizeof(resp)); Using Coccinelle: @@ identifier resp; expression udata; @@ - ib_copy_to_udata(udata, &resp, sizeof(resp)) + ib_respond_udata(udata, resp) Run another pass with AI to propagate the return code correctly and remove redundant prints.

RDMA/ocrdma: Don't NULL deref uctx on errors in ocrdma_copy_pd_uresp()

2026-05-02T18:30:48+00:00

Sashiko points out that pd->uctx isn't initialized until late in the function so all these error flow references are NULL and will crash. Use the uctx that isn't NULL.
