Expected results:
Expected not to fail
Additional info:
The bug is in below snippet. If bind-address is IPv6, *addr_len will be
non-zero and it goes to ret = -1 branch, which will cause listen failure
eventually.
rpc/rpc-transport/socket/src/name.c
/* IPV6 server can handle both ipv4 and ipv6 clients */
for (rp = res; rp != NULL; rp = rp->ai_next) {
if (rp->ai_addr == NULL)
continue;
if (rp->ai_family == AF_INET6) { ==============1
memcpy(addr, rp->ai_addr, rp->ai_addrlen);
*addr_len = rp->ai_addrlen;
}
}
if (!(*addr_len) && res && res->ai_addr) {
memcpy(addr, res->ai_addr, res->ai_addrlen);
*addr_len = res->ai_addrlen;
} else { ==================2
ret = -1;
}
freeaddrinfo(res);
