9e01adfa90 main: don't show help text anymore when we detect an unknown kernel cmdline value starting with "systemd."
As generators and other components started to maintain their own kernel
command line options this help text needed more and more exceptions and
wasn't complete anyway. Fixing that would leak more information about
specific generators into PID 1, which we should avoid.

Given that kernel cmdline handling traditionally doesn't generate errors
or show help texts, let's just remove the logic for it for systemd too.

c806ffb959 sd-dhcp6-client: Initialize fd to -1 and rename function
client_initialize name is misleading, since the function is actually
useful at the *end*, to reinitialize the object. But reset is shorter,
so rename it to client_reset.

4138fb2c79 networkd: Add initial DHCPv6 support
Enable DHCPv6 support by creating a DHCPv6 boolean in the Network
section. Add necessary DHCPv6 structures and initial function calls.

947527f832 sd-dhcp6-client: Add reply sending for test

Reply the callback function will be called and the additional
earlier event loop exit can now be removed.

5e256ea7d3 sd-dhcp6-client: Add Advertise sending for test case
Enhance the test case by replying with an Advertise message to the
client. Copy the transaction id, IAID and DUID from the Solicit
message. Verify the Request message created by the DHCPv6 client
implementation and move the main loop exit to the end of the Request
message verification.

7246333cb8 sd-dhcp6-client: Add Request message sending
As described in RFC 3315, Section 17.1.2, a client has to wait until the
first timeout has elapsed before it is allowed to request IPv6 addresses
from the DHCPv6 server. This is indicated by a non-NULL lease and a
non-zero resend count. Should the Advertisement contain a preference
value of 255 or be received after the first timeout, IPv6 address
requesting is started immediately.

In response to these events, create a Request message and set up proper
resend timers to send the message to the server.

859cca44f8 sd-dhcp6-client: Add test case for Advertise message parsing
Add a basic test case excersising once more option parsing function
in addition to lease handling. Check that the address iteration
functions return the correct IPv6 address and lifetimes and that
only one address is returned. Also verify that the server ID and
preference values are read correctly.

ea3b3a75ab sd-dhcp6-lease: Add functions for accessing lease and addresses

as iterating over the addresses and get their preferred and valid
lifetimes.

631bbe7129 sd-dhcp6-client: Receive and parse Advertise messages
When receiving DHCPv6 messages, discard the ones that are not meant
for DHCPv6 clients and verify the transaction id. Once that is done,
process the Advertise message and select the Advertise with the
highest preference.

Create a separate function for lease information parsing so that it
can be reused in other parts of the protocol. Verify both DUID and
IAID in the received message and store other necessary information
with the lease structure.

c6affce874 sd-dhcp6-client: Add IA Address option parsing
Add functionality to parse DHCPv6 Identity Association for
Non-temporary (IA_NA) and Temporary Addresses (IA_TA) options.
Both of them contain one or more IA Address (IAADDR) options
and optinally a status code option. Only the IA_NA option
contains lease lifetimes. See RFC 3315, sections 22.4., 22.5.,
22.6., 22.13. and appendix B. for details. If the lease
timeouts are not set, use the ones recommended for servers in
section 22.4.

Factor out common code in the form of an option header parsing
helper function.

3fb2c57038 sd-dhcp6-lease: Add DHCPv6 lease handling
Create a structure describing a DHCPv6 lease. Add internal functions
for creating a new lease and accessing the server ID, preference and
IAID. Provide functions for clearing addresses and associated timers.

External users are initially given only the capabilities of
referencing and unreferencing the lease structure.

2ea8857eff sd-dhcp6-client: Add DHCPv6 Solicit test case
Verify the Solicit message created by the DHCPv6 client code.

Provide local variants for detect_vm(), detect_container() and
detect_virtualization() defined in virt.h. This makes the DHCPv6
library believe it is run in a container and does not try to request
interface information from udev for the non-existing interface index
used by the test case code.

a9aff3615b sd-dhcp6-client: Add DHCPv6 Solicit message creation and sending
Implement the initial functionality used for creating a DHCPv6 Solicit
message containing the needed options and send it to the DHCPv6
broadcast address. Increase the sent message count and ensure that
the Solicit Initial Retransmission Time is strictly greater than
the Solicitation IRT as described in RFC 3315, section 17.1.2.

34e8c5a23c sd-dhcp6-client: Add functions to bind to DHCPv6 UDP socket
Add a function that creates a UDP socket bound to the given interface
and optionally to an IPv6 address. Add another function that will
send the DHCPv6 UDP packet to its destination.

Using IPV6_PKTINFO in setsockopt to bind the IPv6 socket to an
interface is documented in section 4. of RFC 3542, "Advanced Sockets
Application Program Interface (API) for IPv6"

Add a define for DHCPv6 Relay Agents and Servers multicast address as
its not available elsewhere.

f12ed3bf0b sd-dhcp6-client: Add basic DHCPv6 option handling
Add option appending and parsing. DHCPv6 options are not aligned, thus
the option handling code must be able to handle options starting at
any byte boundary.

d1b0afe365 sd-dhcp6-client: Add DHCPv6 client Solicitation timeout handling
Add the core of DHCPv6 client message retransmission and upper bound
timer and message count handling according to RFC 3315 Secions 7.1.2
and 14. Omit the DHCPv6 initial delay; for now it is assumed that
systemd-networkd will provide decent startup randomization that will
desynchronize the clients.

When reinitializing the client, clear all timers.

f12abb48fc sd-dhcp6-client: Add DHCPv6 IAID functionality
Create structures describing Identity Association IDentifiers and
IPv6 lease addresses.

[tomegun: initialize the IAID when client is started. Base this off of the
predictable udev names, if available, as these satisfy the requirement of
the IAID, and base it off the mac addres otherwise, as that is the best we
have.]

a276e6d686 sd-dhcp6-client: Initialize DUID

DUID is generated based on the machine-id, which satisfies all the
requirements of what an DUID should be. The DUID type is DUID-EN.

e316912679 sd-icmp6-nd: Add Router Solicitation and Advertisement support
Provide functions to bind the ICMPv6 socket to the approriate interface
and set multicast sending and receiving according to RFC 3493, section
5.2. and RFC 3542, sections 3. and 3.3. Filter out all ICMPv6 messages
except Router Advertisements for the socket in question according to
RFC 3542, section 3.2.

Send Router Solicitations to the all routers multicast group as
described in RFC 4861, section 6. and act on the received Router
Advertisments according to section 6.3.7.

Implement a similar API for ICMPv6 handling as is done for DHCPv4 and
DHCPv6.
