2014-02-16sd-dhcp: silently ignore malformed packetsTom Gundersen
This fixes a regression introduced in e5002702.
2014-02-15sd-dhcp: network - don't hardcode portsTom Gundersen
We want to reuse these functions for the server library too.
2014-02-15sd-dhcp: minimum options size is part of the protocolTom Gundersen
2014-02-15sd-dhcp-client: explicitly handle raw and udp messagesTom Gundersen
Split the recevie_message callback into _raw and _udp parts and a generic DHCPMessage handler. Also always verify the xid/MAC, rather than only for udp messages.
2014-02-12sd-dhcp: make sure client->secs > 0Tom Gundersen
Some DHCP servers will not work correctly if secs == 0, so round up to at least 1.
2014-02-11sd-dhcp: split out packet handling from clientTom Gundersen
2014-02-07sd-dhcp-client: split sd_dhcp_lease from sd_dhcp_clientTom Gundersen
This allows us users of the library to keep copies of old leases. This is used by networkd to know what addresses to drop (if any) when the lease expires. In the future this may be used by DNAv4 and sd-dhcp-server.
2014-01-31libsystemd-dhcp: Update secs field only when sending DiscoverPatrik Flykt
Compute the 'secs' field as seconds since start of lease acquisition procedure. Start off with a value of zero and increase it only for each resent DHCP discover message. See the discussion before and after http://www.ietf.org/mail-archive/web/dhcwg/current/msg05836.html and Section 3.1 of RFC 2131.
2014-01-31libsystemd-dhcp: Fix stopping of DHCP clientPatrik Flykt
Go back to Init state independent of the current state the client is in.
2014-01-31libsystemd-dhcp: Compute UDP checksum only if setPatrik Flykt
A checksum field with value zero means no UDP checksum has been computed for the packet.
2014-01-31libsystemd-dhcp: Rename function to be clearer that options are parsedPatrik Flykt
2014-01-31libsystemd-dhcp: DNS name option must be a multiple of 4 bytesPatrik Flykt
2014-01-30sd-dhcp-client/net-util: make netmask_to_prefixlen genericTom Gundersen
This was originally included in the dhcp-client at my request, but it is not really dhcp-specific and useful outside of it, so let's pull it out.
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.
