Merge pull request #12160 from yuwata/wait-online-allow-configuring 
wait-online: add --any option

Yu Watanabe 2f9859baa8 wait-online: add --any option 
When this option is specified, wait-online exits with success even
when several interfaces are in configuring state.

Closes #9714.

Yu Watanabe 3abf950fdb network: do not ignore FooOverUDP.Encapsulation= setting

Yu Watanabe b519908cac network: do not abort execution when NetDev.Name= conflicts 
This also changes that .netdev files are loaded in ascending order.
Otherwise, when NetDev.ifname= setting conflicts with other .netdev file,
then .netdev file with large prefix number wins.

Jörg Thalheim 7232c1f9da wireguard: fix exponential backoff when resolving hosts 
It should stop at 25s, not start.
Fixes #12134

Zbigniew Jędrzejewski-Szmek 10c353e1c5 Remove variable only used for an assert 
When compiled with -DNDEBUG, we get warnings about set-but-unused variables.
In general, it's not something we care about, but since removing those
variables arguably makes the code nicer, let's just to it in this case.

Lennart Poettering 6990fb6bc6 tree-wide: (void)ify a few unlink() and rmdir() 
Let's be helpful to static analyzers which care about whether we
knowingly ignore return values. We do in these cases, since they are
usually part of error paths.
 2019-03-27 18:09:56 +01:00
Zbigniew Jędrzejewski-Szmek ca78ad1de9 headers: remove unneeded includes from util.h 
This means we need to include many more headers in various files that simply
included util.h before, but it seems cleaner to do it this way.

Yu Watanabe 3a27af62b5 network: wait for L2TP tunnel to be created before creating sessions 
And if failed to create L2TP tunnel, then do not try to create sessions.
 2019-03-14 10:57:41 +09:00
Yu Watanabe d053d08a37 network: automatically pick an address on link when L2TP.Local= is not specified 
This makes L2TP.Local= support an empty string, 'auto', 'static', and
'dynamic'. When one of the values are specified, a local address is
automatically picked from the local interface of the tunnel.

Susant Sahani 3a56e697c8 networkd: Introduce l2tp tunnel

If some of stacked netdevs are already configured, then link_joined()
is called before netdevs are fully configured.

Yu Watanabe f023184e6d wait-online: support $REQUIRED_OPER_STATE_FOR_ONLINE= in state file 
This also make wait-online optionally take operstate in -i option,
and adds '--operstate' option to wait-online which also takes operstate.

Also, this contains huge refactoring for wait-online.
 2019-03-13 14:29:03 +09:00
Yu Watanabe 4ac77d63e9 network: make RequiredForOnline= also take operational state 
This will be used by systemd-networkd-wait-online.

Yu Watanabe c9cc038343 network: introduce 'degraded-carrier' operstate to order all states 
Previously, 'degraded' state is ambiguous for bonding or bridge master:
1. one or more slave interfaces does not have carrier,
2. no link local address is assigned to the master,
3. combination of the above two.

This makes the above case 1 and 3 are in the new 'degraded-carrier'
state, and makes 'degraded' state as all slaves are active but no
link local address on master.
