2018-06-18RDMA: Convert drivers to use sgid_attr instead of sgid_indexParav Pandit16-237/+96
The core code now ensures that all driver callbacks that receive an rdma_ah_attrs will have a sgid_attr's pointer if there is a GRH present. Drivers can use this pointer instead of calling a query function with sgid_index. This simplifies the drivers and also avoids races where a gid_index lookup may return different data if it is changed.

2018-06-18IB{cm, core}: Introduce and use ah_attr copy, move, replace APIsJason Gunthorpe6-6/+70
Introduce AH attribute copy, move and replace APIs to be used by core and provider drivers. In CM code flow when ah attribute might be re-initialized twice while processing incoming request, or initialized once while from path record while sending out CM requests. Therefore use rdma_move_ah_attr API to handle such scenarios instead of memcpy(). Provider drivers keeps a copy ah_attr during the lifetime of the ah. Therefore, use rdma_replace_ah_attr() which conditionally release reference to old ah_attr and holds reference to new attribute whose referrence is released when the AH is freed.

2018-06-18IB/core: Add a sgid_attr pointer to struct rdma_ah_attrJason Gunthorpe2-27/+232
The sgid_attr will ultimately replace the sgid_index in the ah_attr. This will allow for all layers to have a consistent view of what gid table entry was selected as processing runs through all stages of the stack. This commit introduces the pointer and ensures it is set before calling any driver callback that includes a struct ah_attr callback, allowing future patches to adjust both the drivers and the callers to use sgid_attr instead of sgid_index.

2018-06-18IB/core: Introduce GID entry reference countsParav Pandit2-103/+221
In order to be able to expose pointers to the ib_gid_attrs in the GID table we need to make it so the value of the pointer cannot be changed. Thus each GID table entry gets a unique piece of kref'd memory that is written only during initialization and remains constant for its lifetime. This eventually will allow the struct ib_gid_attrs to be returned without copy from many of query the APIs, but it also provides a way to track when all users of a HW table index go away. For roce we no longer allow an in-use HW table index to be re-used for a new an different entry. When a GID table entry needs to be removed it is hidden from the find API, but remains as a valid HW index and all ib_gid_attr points remain valid. The HW index is not relased until all users put the kref. Later patches will broadly replace the use of the sgid_index integer with the kref'd structure. Ultimately this will prevent security problems where the OS changes the properties of a HW GID table entry while an active user object is still using the entry.
