[systemd-devel] [PATCH 00/11] DHCPv6 DNS and NTP information

[Patrik Flykt]

	Hi,

This patch set adds support for DNS and NTP DHCPv6 options. The information
obtained is written to file in link_save() in systemd-networkd in order
to be used by others.

The first patch is a bug fix triggered when going from Information request
to the full DHCPv6 address lease in the test case when the lease was also
stored as a part of the information request exchange in patch two.

Two helper functions are introduced and used when extracting DNS, NTP
address, domain search list and NTP host name options. Support was added
also for the deprecated SNTP option, it can still be discovered in some
semi-ancient networks.

The test case is improved to look for the DNS and NTP information and
ystemd-networkd is enhanced with the functionality to write this information
nto the link state file. I might be missing something with systemd-networkd
n this area, though.

I do feel a bit rusty with systemd, some conventions may have changed since
last time.

Please review,

       Patrik
