</div><pre style="font-family: monospace,monospace; white-space: pre-wrap;">Introduce SS7 IPv6 support<br><br>In osmo_ss7_vty_go_parent, "127.0.0.1" is changed to "localhost" to let<br>local NSS decide whether to use IPv4 or IPv6. In newish systems, IPv6<br>::1 will be selected since IPv6 takes precedence over IPv4.<br><br>Similarly, the default source addr needs to be changed from NULL to "localhost"<br>since for some yet unknwon reason, getaddrinfo(AF_UNSPEC, NULL) returns<br>first IPv4 "0.0.0.0" and later "::", which is inconsistent with<br>getaddrinfo("localhost") result, resulting in src=IPv4(0.0.0.0) and<br>dst=IPv6(::1), which is incompatible and will fail.<br>In any case, this change doesn't affect users of osmo_sccp_simple_client<br>because the APIs set both src and dst addresses.<br><br>Change-Id: I69c48819b70635c92fa404cafd917af7802d517c<br>Depends: libosmo-netif.git Change-Id Ie6bb17a9af6ca21d5e350f9c9d2d74c97c5a00af<br>---<br>M
