2014-06-19sd-dhcp6-client: Receive and parse Advertise messagesPatrik Flykt
When receiving DHCPv6 messages, discard the ones that are not meant for DHCPv6 clients and verify the transaction id. Once that is done, process the Advertise message and select the Advertise with the highest preference. Create a separate function for lease information parsing so that it can be reused in other parts of the protocol. Verify both DUID and IAID in the received message and store other necessary information with the lease structure.
2014-06-19sd-dhcp6-client: Add DHCPv6 Solicit message creation and sendingPatrik Flykt
Implement the initial functionality used for creating a DHCPv6 Solicit message containing the needed options and send it to the DHCPv6 broadcast address. Increase the sent message count and ensure that the Solicit Initial Retransmission Time is strictly greater than the Solicitation IRT as described in RFC 3315, section 17.1.2.
2014-06-19sd-dhcp6-client: Add DHCPv6 client Solicitation timeout handlingPatrik Flykt
Add the core of DHCPv6 client message retransmission and upper bound timer and message count handling according to RFC 3315 Secions 7.1.2 and 14. Omit the DHCPv6 initial delay; for now it is assumed that systemd-networkd will provide decent startup randomization that will desynchronize the clients. When reinitializing the client, clear all timers.
2014-06-19sd-dhcp6-client: Add DHCPv6 IAID functionalityPatrik Flykt
Create structures describing Identity Association IDentifiers and IPv6 lease addresses. [tomegun: initialize the IAID when client is started. Base this off of the predictable udev names, if available, as these satisfy the requirement of the IAID, and base it off the mac addres otherwise, as that is the best we have.]
2014-06-19sd-dhcp6-client: Initialize DUIDTom Gundersen
Initialize DHCP Unique Identifier when creating the client. The DUID is generated based on the machine-id, which satisfies all the requirements of what an DUID should be. The DUID type is DUID-EN. Based on patch by Patrik Flykt.
2014-06-19sd-dhcp6-client: Add initial DHCPv6 client filesPatrik Flykt
Add initial structure definition and functions for setting index, MAC address, callback and event loop. Define protocol values and states.
