My understanding is that support for loopback addresses exposes an existing bug in openmpi. It tries to bind to 127.0.0.1, which now succeeds. Openmpi passes that address to a remote node for use in connections. >I'm most concerned that there is another regression in 2.6.33, and if so >I would like to try and avoid letting that get into the final release. Unless we never support loopback addresses, openmpi will see a regression. The only other problem that I'm aware of for 2.6.33 is that the bind to a loopback address will succeed, even though the RDMA device may not support loopback. This is true for the Chelsio and Ammasso drivers. Connections should still fail, but the bind is basically useless in this case. I will try to get a patch for that tomorrow. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
