BTW, sifting through the OFED 1.3 libibverbs tree, I do see that the commit to add max_xrc_domains to struct ibv_device_attr did break things by adding the member in the middle of the structure (so that an app compiled against the old header will see bogus values for local_ca_ack_delay and phys_port_count.
Actually looking at the commit again, it's worse than that... anything compiled against the old header that calls ibv_query_device() may get memory corrupted, because the new ibv_query_device() writes to a bigger structure than the app passes in. The perils of not reviewing properly I guess... - R. _______________________________________________ ewg mailing list ewg@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg
