Bob Pearson 5ff31dfcd6 Subject: RDMA/rxe: Handle zero length rdma ... Currently the rxe driver does not handle all cases of zero length rdma operations correctly. The client does not have to provide an rkey for zero length RDMA read or write operations so the rkey provided may be invalid and should not be used to lookup an mr. This patch corrects the driver to ignore the provided rkey if the reth length is zero for read or write operations and make sure to set the mr to NULL. In read_reply() if length is zero rxe_recheck_mr() is not called. Warnings are added in the routines in rxe_mr.c to catch NULL MRs when the length is non-zero.
