2014-02-15sd-dhcp: network - don't hardcode portsTom Gundersen
We want to reuse these functions for the server library too.
2014-01-21libsystemd-dhcp: revert merge into libsystemdTom Gundersen
Unlike the other merged libs, the rest of libsystemd will never depend on sd-dhcp-client, so there is no reason not to keep it separate.

2013-12-22libsystemd-dhcp: add some assertsTom Gundersen
2013-12-22libsystemd-dhcp: Add functions for sending unicast UDP messagesPatrik Flykt
Create a helper functions setting up an unicast DHCP UDP socket and sending data. Add function stubs for the test program. [tomegun: initialize structs when allocating, and drop unneccesary 'err']
2013-12-22libsystemd-dhcp: Return proper error if bind failsPatrik Flykt
This also fixes a minor indentation damage. [tomegun: use close_noint_nofail() instead and drop 'err' variables]
2013-12-12dhcp: Handle received DHCP Offer messagePatrik Flykt
Create a function for handling the full IP, UDP and DHCP packet and tie it to the main loop. Verify IP and UDP headers and checksum. Creat a new lease structure with using the values supplied in the DHCP message. Free the lease structure when client is stopped. Split out socket handling into a creation and a sending part. As a result modify the test code.
2013-12-12dhcp: Add function for sending a raw packetPatrik Flykt
Open a packet socket, create a link level header, send packet and close socket. Adding it to a separate file makes testing of the DHCP sending much easier, as the test program can supply any socket to the DHCP client code.
