[PATCH 4.14 083/189] IB: make INFINIBAND_ADDR_TRANS configurable

From: Greg Kroah-Hartman
Date: Mon Jun 18 2018 - 04:34:24 EST


4.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Greg Thelen <gthelen@xxxxxxxxxx>

[ Upstream commit f7cb7b85be55a4906b4b4b30596db1043dae6335 ]

Allow INFINIBAND without INFINIBAND_ADDR_TRANS because fuzzing has been
finding fair number of CM bugs. So provide option to disable it.
