Ticket #3484 Note that for now prefixlen is useless in ipv6 tunnels. IPv4 accepts them

Fix #3483 only use IPv4 DNS servers in DHCP v4 conf

Version for 2.1 branch

Make is_linklocal case-insensitive and fix #3433

Properly detect when there are issues with communicating with syncip and to use the local DB for this. Otherwise detect if the remote says the voucher is not valid say its not valid.

Properly compile the query to insert the values. Pointy-hat: myself. While here respect the redirurl when passed to portal_allow and use proper function to do redirection.

Ticket #2627. Just pass the array over no need to traverse it

Fixes #2627. When an interface goes down try to shut the RAs and dhcpd6 service on that interface

Avoid recursion of convert_real_interface_to_friendly_interface_name with get_parent and on linkup of parent interface properly configure especially useful on ppp type links

Be friendly to memory

Fix problem with the voucher synching that was introduced during conversion to zones
