This patch series primarily increases sizes of variables that hold lid values from 16 to 32 bits. Additionally, it adds a check in the IB mad stack to verify a properly formatted MAD when OPA extended LIDs are used. Changes from v3: --------------- * Add 'IB/core: Add functions to convert 32 bit lids to 16 bits' and use them in place of casts. Changes from v2: --------------- * Remove 'IB/mad: Ensure DR MADs are correctly specified when using OPA devices' as this will be handled in a lower layer. Changes from v1: --------------- * Remove extraneous slid set. * Replace slid casts with helper function. * Return default subnet prefix on rdma_ah_conv_opa_to_ib() failure. The patches are origanized as follows: * Patch 1 converts an OPA ah_attr to an IB ah_attr when copying from kernel to user. Since OPA ah_attr is only defined in the kernel, the function takes care of adding OPA GIDs that contain the extended LID before copying to user. * Patch 2 increases the lid and sm_lid variables in srpt to 32 bits. * Patch 3 increases the local_lid variable in IPoIB to 32 bits. * Patch 4 increases the slid variable in MAD RMPP to 32 bits. * Patch 5 Adds functions to convert 32 bit lids to 16 bits. * Patch 6 increases the lid field in struct ib_port_attr from 16 to 32 bits. * Patch 7 increases the sm_lid field in struct ib_port_attr from 16 to 32 bits. * Patch 8 increases the slid field in struct ib_wc from 16 to 32 bits.
