The "lg" variable is declared as int so in all places where this variable is used as a shift operand, the output will be int too. This produces the following smatch warning: drivers/infiniband/hw/mthca/mthca_cmd.c:701 mthca_map_cmd() warn: should '1 << lg' be a 64 bit type? Simple declaration of "1" to be "1ULL" will fix the issue. Signed-off-by:

When rdma_cm is initializing a cma_device it checks if this device supports the preferred default GID type. This check was done in a wrong way and therefore sometimes rdma_cm is coming up with default GID type that is not supported by the device. Fix that by checking for supported GID type properly.

Commit 44c58487 ("IB/core: Define 'ib' and 'roce' rdma_ah_attr types") introduced the concept of type in ah_attr: * During ib_register_device, each port is checked for its type which is stored in ib_device's port_immutable array. * During uverbs' modify_qp, the type is inferred using the port number in ib_uverbs_qp_dest struct (address vector) by accessing the relevant port_immutable array and the type is passed on to providers. IB spec (version 1.3) enforces a valid port value only in Reset to Init. During Init to RTR, the address vector must be valid but port number is not mentioned as a field in the address vector, so its value is not validated, which leads to accesses to a non-allocated memory when inferring the port type. Save the real port number in ib_qp during modify to Init (when the comp_mask indicates that the port number is valid) and use this value to infer the port type. Avoid copying the address vector fields if the matching bit is not set in the attr_mask. Address vector can't be modified before the port, so no valid flow is affected.

The current timeout logic for Control Queue-Pair (CQP) OPs does not take into account whether CQP makes progress but rather blindly waits for a large timeout value, 100000 jiffies for the completion event. Improve this by setting the timeout based on whether the CQP is making progress or not. If the CQP is hung, the timeout will happen sooner, in 5000 jiffies. Each time the CQP progress is detetcted, the timeout extends by 5000 jiffies. Signed-off-by:
