Hello, does it possible to use rdma_getaddrinfo and specify in node port GUID? I'm try with fe80:0000:0000:0000:0002:c903:00ef:6651 this simple test: #include <stdlib.h> #include <stdio.h> #include <rdma/rdma_cma.h> #include <infiniband/ib.h> int main(int argc, char **argv) { struct rdma_addrinfo *hints, *info; int ret = -1; hints = malloc(sizeof(hints)); memset(hints, '\0', sizeof(hints)); hints->ai_flags = RAI_NUMERICHOST; hints->ai_family = AF_IB; // hints->ai_port_space = RDMA_PS_IB; ret = rdma_getaddrinfo(argv[1], NULL, hints, &info); if (ret < 0) { fprintf(stderr, "%d rdma_getaddrinfo\n", ret); return ret; } if (info == NULL) { fprintf(stderr, "%d rdma_getaddrinfo null\n", ret); return -1; } return 0; } But getting INET6 address Also noted that i don't enable IPoIB, why address not IF_IB family ? -- Vasiliy Tolstov, e-mail: v.tolstov@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
