2017-03-27udhcp6: fix releasingDenys Vlasenko
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.

2017-03-27udhcp6: fix problems found running against dnsmasqDenys Vlasenko
Patch is based on work by tiggerswelt.net. They say: " But when we tried to use dnsmasq on server-side, udhcpc6 was unable to forward the acquired address to its setup-script although the IPv6-Address had been assigned by the server as we could see via tcpdump. We traced this issue down to a problem on how udhcpc6 parses DHCPv6-Options: When moving to next option, a pointer-address is increased and a length buffer is decreased by the length of the option. The problem is that it is done in this order: option += 4 + option[3]; len_m4 -= 4 + option[3]; But this has to be switched as the length is decreased by the length of the *next* option, not the current one. This affected both - internal checks if a required option is present and the function to expose options to the environment of the setup-script. There was also a bug parsing D6_OPT_STATUS_CODE Options, that made dnsmasq not work as udhcpc6 thought it is receiving a non-positive status-code (because it did not parse the status-code as required in RFC 3315). In addition we introduced basic support for RFC 3646 (OPTION_DNS_SERVERS and OPTION_DOMAIN_LIST) and RFC 4704 (OPTION_CLIENT_FQDN). " Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Good news that TLS_RSA_WITH_AES_256_CBC_SHA256 still works with new code ;) This change adds inevitable extension to have different sized hashes and AES key sizes. In libbb, md5_end() and shaX_end() are extended to return result size instead of void - this helps *a lot* in tls (the cost is ~5 bytes per _end() function).
