            Bug ID: 52557
           Summary: GetNetworkParams loops forever on musl
           Product: Wine
           Version: 7.2
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: iphlpapi
          Assignee: wine-bugs at winehq.org
          Reporter: me at atiltedtree.dev
      Distribution: ---

On musl, res_getservers does not exist and dnsapi/resolv_get_serverlist will
fall back to res_state.nsaddr_list. But musl also does not set
res_state.nsaddr_list causing dnsapi/resolv_get_serverlist to always return
DNS_ERROR_NO_DNS_SERVERS.

iphlpapi/get_dns_server_list will call DnsQueryConfig( DnsConfigDnsServerList,
...), which calls dnsapi/resolv_get_serverlist, until it does not return an
error, but on musl it will always return an error causing
iphlpapi/get_dns_server_list to loop infinitely. 

This means that any application that calls iphlpapi.GetNetworkParams or
iphlpapi.GetPerAdapterInfo will loop infinitely, if wine was built on musl.
