[infiniband] Return status code from ib_create_cq() and ib_create_qp()

2017-03-22T09:18:02+00:00

Any underlying errors arising during ib_create_cq() or ib_create_qp() are lost since the functions simply return NULL on error. This makes debugging harder, since a debug-enabled build is required to discover the root cause of the error. Fix by returning a status code from these functions, thereby allowing any underlying errors to be propagated. Signed-off-by: Michael Brown

[infiniband] Avoid multiple calls to ib_cmrc_shutdown()

2016-03-08T12:07:03+00:00

When a CMRC connection is closed, the deferred shutdown process calls ib_destroy_qp(). This will cause the receive work queue entries to complete in error (since they are being cancelled), which will in turn reschedule the deferred shutdown process. This eventually leads to ib_destroy_conn() being called on a connection that has already been freed. Fix by explicitly cancelling any pending shutdown process after the shutdown process has completed. Ironically, this almost exactly reverts commit 019d4c1 ("[infiniband] Use a one-shot process for CMRC shutdown"); prior to the introduction of one-shot processes the only way to achieve a one-shot process was for the process to cancel itself.
