>IMO 127.0.0.1 should be for SW loopback, not HW RDMA loopback. I disagree, but what does it matter? So, we add a 'software' loopback that uses 127.0.0.1. Openmpi still wouldn't work.
>I will commit to get the fix in openmpi asap. If we don't care if the fix is in the kernel or user space, then we could add an a 'disable-loopback-support' build option to librdmacm, which can fail any attempt to bind to a loopback address. -- 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
