Susant Sahani a6f1848a23 network: Allow to configure addr_gen_mode 
Defines how link-local and autoconf addresses are generated.

	0: generate address based on EUI64 (default)
	1: do no generate a link-local address, use EUI64 for addresses generated
	   from autoconf
	2: generate stable privacy addresses, using the secret from
	   stable_secret (RFC7217)
	3: generate stable privacy addresses, using a random secret if unset

Susant Sahani 35f6a5cb44 network: DHCPv6 - Add support set arbitary request options 2020-05-17 11:18:29 +02:00
Lennart Poettering a0b191b705 condition: add ConditionEnvironment= 
Prompted by the discussions in #15180.

This is a bit more complex than I hoped, since for PID 1 we need to pass
in the synethetic environment block in we generate on demand.

Dan Streetman 589397a277 network: change UseGateway= default to UseRoutes= setting 
Anyone previously using the UseRoutes=false parameter expected their
dhcp4-provided gateway route to be ignored, as well.  However, with
the introduction of the UseGateway= parameter, this is no longer true.

In order to keep backwards compatibility, this sets the UseGateway=
default value to whatever UseRoutes= has been set to.

David Wood 7354900ddd network: Fix split in SendOption= on client and server 
When specifying `DHCPv4.SendOption=`, it is used by systemd-networkd to
set the value of that option within the DHCP request that is sent out.
This differs to setting `DHCPServer.SendOption=`, which will place all
the options together as suboptions into the vendor-specific information
(code 43) option.

This commit adds two new config options, `DHCPv4.SendVendorOption=` and
`DHCPServer.SendVendorOption=`. These both have the behaviour of the old
`DHCPServer.SendOption=` flag, and set the value of the suboption in the
vendor-specific information option.

The behaviour of `DHCPServer.SendOption=` is then changed to reflect
that of `DHCPv4.SendOption=`. It will set the value of the corresponding
option in the DHCP request.

concept and algorithm, and "Fair queue" is mostly used for the implementation
name.

Zbigniew Jędrzejewski-Szmek dade734917 network,udev: refuse .link and .network settings with no matches 
Two releases ago we started warning about this, and I think it is now to turn
this into a hard error. People get bitten by this every once in a while, and
there doesn't see to be any legitimate use case where the same .link or
.network files should be applied to _all_ interfaces, since in particular that
configuration would apply both to lo and any other interfaces. And if for
whatever reason that is actually desired, OriginalName=* or Name=* can be
easily added to silence the warning and achieve the effect.

(The case described in #12098 is particularly nasty: 'echo -n >foo.network'
creates a mask file, 'echo >foo.network' creates a "match all" file.)

Fixes #717, #12098 for realz now.
