Abstract:
1. A method for providing subnet management packet (SMP) firewall restrictions in a middleware machine environment operable on one or more microprocessors, comprising: providing a secure firmware implementation on a host channel adaptor (HCA) that connects to an infiniband (IB) fabric, wherein the HCA is associated with a host; receiving at least one SMP via the secure firmware implementation, wherein the at least one SMP is either received from the host or destined for the host; preventing, via the secure firmware implementation, the host from sending the at least one SMP to the IB fabric or receiving the at least one SMP destined for the host; allowing the secure firmware implementation to include a proxy function, wherein the proxy function can communicate with host software through a local out of band interface; and allowing a subnet manger to send SMPs to host software via the proxy function.
