RDMA/cm: Remove unused cm_class

2020-08-18T18:43:07Z

Previous commits removed all references to the /sys/class/infiniband_cm/ directory represented by the cm_class symbol. Remove the directory and cm_class.

RDMA/include: Replace license text with SPDX tags

2020-07-29T17:48:36Z

The header files in RDMA subsystem are dual licensed and can be described by simple SPDX tag, so replace all of them at once together with making them use the same coding style for header guard defines.

RDMA/cm: Use specific keyword to check define

2019-10-28T13:15:10Z

There is a specific define keyword to check if define exists or not, let's use it instead of open-coded variant. Link: https://lore.kernel.org/r/20191020071559.9743-3-leon@kernel.org Signed-off-by: Leon Romanovsky Reviewed-by: Jason Gunthorpe Signed-off-by: Jason Gunthorpe

RDMA/core: Annotate timeout as unsigned long

2018-10-16T17:34:01Z

The ucma users supply timeout in u32 format, it means that any number with most significant bit set will be converted to negative value by various rdma_*, cma_* and sa_query functions, which treat timeout as int. In the lowest level, the timeout is converted back to be unsigned long. Remove this ambiguous conversion by updating all function signatures to receive unsigned long.

IB/core: Introduce and use sgid_attr in CM requests

2018-07-26T15:47:47Z

For RoCE, when CM requests are received for RC and UD connections, netdevice of the incoming request is unavailable. Because of that CM requests are always forwarded to init_net namespace. Now that we have the GID attribute available, introduce SGID attribute in incoming CM requests and refer to the netdevice of it. This is similar to existing SGID attribute field in outgoing CM requests for RC and UD transports.
