    ipv6: Fixed source specific default route handling. · e16e888b
    Markus Stenberg authored
    If there are only IPv6 source specific default routes present, the
    host gets -ENETUNREACH on e.g. connect() because ip6_dst_lookup_tail
    calls ip6_route_output first, and given source address any, it fails,
    and ip6_route_get_saddr is never called.
    
    The change is to use the ip6_route_get_saddr, even if the initial
    ip6_route_output fails, and then doing ip6_route_output _again_ after
    we have appropriate source address available.
    
    Note that this is '99% fix' to the problem; a correct fix would be to
    do route lookups only within addrconf.c when picking a source address,
    and never call ip6_route_output before source address has been
    populated.
