Now we track the sections for example [Address] via line number.
Which was fine till we din't had dropins dir. If we have multiple
sections which have the ideantical line number in diffrent files
we are overwriting these since line number is the key.
This patch fixes this by taking filename and line number as key.
This fixes [Address] and [Route] section overwriting.

IPv6 Neighbor discovery proxy is the IPv6 equivalent to proxy ARP for IPv4.
It is required when ISPs do not unconditional route IPv6 subnets
to their designated target, but expect neighbor solicitation messages
for every address on a link.
A variable IPv6ProxyNDPAddress= is introduced to the [Network] section,
each representing a IPv6 neighbour proxy entry in the neighbour table.
RDNSS and DNSLL options received in RA are always used, possibly breaking the resolution of private domains hosted on a local DNS server. When setting UseDNS=no in a [IPv6AcceptRA] section of a .network file, both RDNSS and DNSLL options in received RA should be ignored.
Fixes: #5040
In eb64b435eb ActiveSlave/PrimarySlave were inserted in between
IPv6AcceptRA and IPv6AcceptRouterAdvertisements and the comment then didn't
make sense. It turns out that gperf does not understand C-style comments, and
that there's no comment syntax in the keywords section. The following was
generated:
{"/* legacy alias for the above */"},
{"Network.IPv6AcceptRA", config_parse_tristate, 0, offsetof(Network, ipv6_accept_ra)},
In practice this wouldn't lead to problems because this fake pattern would be
hard to match, but it seems better to remove the comments altogether.
Readers of the .gperf file will have to look for the repeated output field to
notice legacy options. To make this easier, let's always keep the legacy option
second.
gperf-3.1 generates lookup functions that take a size_t length
parameter instead of unsigned int. Test for this at configure time.

active_slave:
Specifies the new active slave for modes that support it
(active-backup, balance-alb and balance-tlb).
primary slave:
systemd-networks currently lacks the capability to set the primary slave
in an
active-backup bonding. This is necessary if you prefer one interface
over the
other. A common example is a eth0-wlan0 bonding on a laptop where you'd
want to
switch to the wired connection whenever it's available.

At least bird's implementation of router advertisement does not
set MTU option by default (instead it supplies an option to the user).
In this case just leave MTU as it is.
Otherwise we'd fail with an assertion:
Assertion 't->family == AF_INET' failed at ../src/network/netdev/tunnel.c:244, function netdev_vti_fill_message_create(). Aborting.
When assigning addresses, we'd set the family, and later
verify that the address on the other end has the same family.
But when the address was specified as "any", we'd simply unset
the family. Instead, only unset the family if both addresses
are wiped.
Also, don't bother setting family = AF_UNSPEC, since it's the default (0).
When we are in link_enter_configured we assume that the
link->state should be LINK_STATE_SETTING_ROUTES but in some
situation it's LINK_STATlE_SETTING_ADDRESSES.
Just ignore the wrong state.
Also since the return value not used any where
make link_enter_configured return type void.

This will allow us to have several managers sharing an event loop
and running in parallel, as if they were running in separate processes.
The long term-aim is to allow networkd to be split into separate
processes, so restructure the code to make this simpler.
For now we drop the exit-on-idle logic, as this was anyway severely
restricted at the moment. Once split, we will revisit this as it may
then make more sense again.
If setting the received timezone or transient hostname fails because D-Bus is
not (yet) up, store the data in the Manager object and try again after
connecting to D-Bus.
systemd-networkd runs as user "systemd-network" and thus is not privileged to
set the timezone acquired from DHCP:
systemd-networkd[4167]: test_eth42: Could not set timezone: Interactive authentication required.
Similarly to commit e8c0de912, add a polkit rule to grant
org.freedesktop.timedate1.set-timezone to the "systemd-network" system user.
Move the polkit rules from src/hostname/ to src/network/ to avoid too many
small distributed policy snippets (there might be more in the future), as it's
easier to specify the privileges for a particular subject in this case.
Add NetworkdClientTest.test_dhcp_timezone() test case to verify this (for
all people except those in Pacific/Honolulu, there the test doesn't prove
anything -- sorry ☺ ).
Never propagate DNS/NTP servers on the local link via the DHCP server. The
DNS/NTP servers 0.0.0.0 and 127.0.0.1 only make sense in the local context,
hence never propagate them automatically to other hosts.
Fixes: #4524
DNS servers must be specified as IP addresses, hence let's store them as that
internally, so that they are guaranteed to be fully normalized always, and
invalid data cannot be stored.
Let's reorder them a bit, so that stuff that belongs together semantically is
placed together (in particular, move the various DHCP "use" booleans together).
When systemd-networkd is run on the same IPv6 enabled interface where
radvd is announcing prefixes, a route is being set up pointing to the
interface address. As this will fail with an invalid argument error,
the link is marked as failed and the following message like the
following will appear in in the logs:
systemd-networkd[21459]: eth1: Could not set NDisc route or address: Invalid argument
systemd-networkd[21459]: eth1: Failed
Should the interface be required by systemd-networkd-wait-online,
network-online.target will wait until its timeout hits thereby
significantly delaying system startup.
The fix is to check whether the gateway address obtained from NDisc
messages is equal to any of the interface addresses on the same link
and not set the NDisc route in that case.
