[systemd-devel] [PATCH 00/11] Finalize initial DHCP support

[Patrik Flykt]

	Hi,

The first seven patches fix a few issues with the current code.

Patch 09 adds DHCP lease renewing support when timer T1 triggers. Using
the UDP socket sending implementation in patch 08, the DHCP lease
renewal is unicasted to the DHCP server. This means that systemd-network
should have applied the acquired IP address and default route to the
proper interface before timer T1 triggers.

Common code is factored out in patch 10, which makes patch 11 containing
the broadcasting of DHCP Requests at timer T2 trigger quite small.

At this point in time support for fetching DNS, NTP, etc options from
the DHCP message(s) is still missing, sorry for that. Also Init-Reboot
state support is missing; adding that functionality can speed up the
address acquisition if the host comes back to a known network where
it still has an unexpired lease.


Please review,
