IB: move from strlcpy with unused retval to strscpy

2022-08-21T11:18:02Z

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

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/bnxt_re: Use bitmap_zalloc() when applicable

2021-11-29T18:33:56Z

Use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency.

RDMA/bnxt_re: Remove dynamic pkey table

2021-11-25T17:35:51Z

The RoCE spec requires RoCE devices to support only the default pkey. However the bnxt_re driver maintains a 0xFFFF entry pkey table and uses only the first entry. Remove the pkey table and hard code a table of length one hard wired with the default pkey.

RDMA/bnxt_re: Scan the whole bitmap when checking if "disabling RCFW with pending cmd-bit"

2021-11-16T17:54:24Z

The 'cmdq->cmdq_bitmap' bitmap is 'rcfw->cmdq_depth' bits long. The size stored in 'cmdq->bmap_size' is the size of the bitmap in bytes. Remove this erroneous 'bmap_size' and use 'rcfw->cmdq_depth' directly in 'bnxt_qplib_disable_rcfw_channel()'. Otherwise some error messages may be missing. Other uses of 'cmdq_bitmap' already take into account 'rcfw->cmdq_depth' directly.
