Simplify handling of nameserver configuration in resolver
|
||
|
|
|
||
|
|
Remove use of ext.nsmap member of struct __res_state and always use
|
||
|
|
an identity mapping betwen the nsaddr_list array and the ext.nsaddrs
|
||
|
|
array. The fact that a nameserver has an IPv6 address is signalled by
|
||
|
|
setting nsaddr_list[].sin_family to zero.
