Patch is based on work by tiggerswelt.net. They say: " We wanted udhcpc6 to release its IPv6-Addresses on quit (-R-commandline-option) which turned out to generate once again kind of garbage on the network-link. We tracked this down to two issues: - udhcpc6 uses a variable called "srv6_buf" to send packets to the dhcp6-server, but this variable is never initialized correctly and contained kind of a garbage-address - The address of the dhcp6-server is usually a link-local-address, that requires an interface-index when using connect() on an AF_INET6- socket We added an additional parameter for ifindex to d6_send_kernel_packet() and made d6_recv_raw_packet() to capture the address of the dhcp6-server and forward it to its callee.
