If trying to parse a string like 192.0.2.2:80/foobar and setting the length to 12 which means to parse the IP address and port, the parsing failed because it used one extra character from the string. This issue was not present if the input string was terminated after the port number. Add a test case to catch this problem. Signed-off-by: Jukka Rissanen <[email protected]>
Allow user to specify a network interface in the DNS server list. User can append "%" and network interface name to the DNS server to use this. If the network interface is mentioned in the server list, then the DNS queries are sent via this network interface. For example setting the interfaces like this: 192.0.2.2%eth1 [2001:db8::2]:5353%ppp0 would cause the DNS queries to sent to 192.0.2.1 via eth1 in the first example, and to 2001:db8::2 via ppp0 in the second example.

If network interface is specified in the DNS server, then send the queries to the server via the network interface. Print this information in the server list. Signed-off-by: Jukka Rissanen <[email protected]>
In this sample, VLAN has longer interface name so increase it to max. Signed-off-by: Jukka Rissanen <[email protected]>
