2019-11-13RDMA: Change MAD processing function to remove extra casting and parameterLeon Romanovsky1-11/+6
All users of process_mad() converts input pointers from ib_mad_hdr to be ib_mad, update the function declaration to use ib_mad directly. Also remove not used input MAD size parameter.

2019-05-14RDMA: Directly cast the sockaddr union to sockaddrJason Gunthorpe1-3/+2
gcc 9 now does allocation size tracking and thinks that passing the member of a union and then accessing beyond that member's bounds is an overflow. Instead of using the union member, use the entire union with a cast to get to the sockaddr. gcc will now know that the memory extends the full size of the union.

2019-05-03RDMA: Introduce and use GID attr helper to read RoCE L2 fieldsParav Pandit1-4/+5
Instead of RoCE drivers figuring out vlan, smac fields while working on QP/AH, provide a helper routine to read the L2 fields such as vlan_id and source mac address. This moves logic from mlx5 driver to core for wider usage for RoCE ports. This is a preparation patch to allow detaching netdev in subsequent patch.

2019-04-08RDMA: Handle AH allocations by IB/coreLeon Romanovsky1-16/+9
Simplify drivers by ensuring lifetime of ib_ah object. The changes in .create_ah() go hand in hand with relevant update in .destroy_ah(). We will use this opportunity and convert .destroy_ah() to don't fail, as it was suggested a long time ago, because there is nothing to do in case of failure during destroy.

2019-04-01IB: Pass uverbs_attr_bundle down ib_x destroy pathShamir Rabinovitch1-1/+1
The uverbs_attr_bundle with the ucontext is sent down to the drivers ib_x destroy path as ib_udata.

2018-06-18RDMA: Convert drivers to use sgid_attr instead of sgid_indexParav Pandit1-15/+9
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.

rdma_ah_attr can now be either ib or roce allowing core components to use one type or the other and also to define attributes unique to a specific type. struct ib_ah is also initialized with the type when its first created.

In order to support alternate sized MADs (and variable sized MADs on OPA devices) add in/out MAD size parameters to the process_mad core call. In addition, add an out_mad_pkey_index to communicate the pkey index the driver wishes the MAD stack to use when sending OPA MAD responses. The out MAD size and the out MAD PKey index are required by the MAD stack to generate responses on OPA devices. Furthermore, the in and out MAD parameters are made generic by specifying them as ib_mad_hdr rather than ib_mad. Drivers are modified as needed and are protected by BUG_ON flags if the MAD sizes passed to them is incorrect.
