83f4c1c9bf core: strip trailing dot from domain search list
dhclient adds a trailing dot to domain search list entries received
from the server, while the same domains received by other means
(dhcpcd on RA) don't have the final dot. The result is that
resolv.conf can be populated with duplicated entries.

Fix this by stripping the trailing dot when a new search domain is
added to a IP configuration.

b78e10a064 core: fix assuming a connection without S390 properties (rh #1276343)
When a connection should be assumed and the generated connection did not
contain a wired setting, the connection did not match due to S390 properties.
Such a connection should be allowed to match to a connection with a wired
setting with default (empty) S390 properties.

This can happen when there is a VLAN profile configured that contains a wired
setting in it and NetworkManager is (re)started.

Example/reproducer:
$ nmcli con add type vlan con-name vlan-test autoconnect no dev em1 id 44
$ nmcli con mod vlan-test eth.mtu 1450   (modify the connection, so that it has a wired setting)
$ nmcli con up vlan-test                 (activate the connection)
$ sudo systemctl restart NetworkManager
$ nmcli device
check that 'vlan-test' connection is active on em1.44 device
(and not the auto-generated em1.44)

e0ca2bdb63 build: extract version macros from "nm-version.h" to new header file "nm-version-macros.h"
For libnm library, "nm-dbus-interface.h" contains defines like the D-Bus
paths of NetworkManager. It is desirable to have this header usable without
having a dependency on "glib.h", for example for a QT application. For that,
commit c0852964a8 removed that dependancy.

For libnm-glib library, the analog to "nm-dbus-interface.h" is
"NetworkManager.h", and the same applies there. Commit
159e827a72 removed that include.
However, that broke build on PackageKit [1] which expected to get the
version macros by including "NetworkManager.h". So at least for libnm-glib,
we need to preserve old behavior so that a user including
"NetworkManager.h" gets the version macros, but not "glib.h".

Extract the version macros to a new header file "nm-version-macros.h".
This header doesn't include "glib.h" and can be included from
"NetworkManager.h". This gives as previous behavior and a glib-free
include.

For libnm we still don't include "nm-version-macros.h" to "nm-dbus-interface.h".
Very few users will actually need the version macros, but not using
libnm.
Users that use libnm, should just include (libnm's) "NetworkManager.h" to
get all headers.
As a special case, a user who doesn't want to use glib/libnm, but still
needs both "nm-dbus-interface.h" and "nm-version-macros.h", can include
them both separately.

2b9f0db807 utils: match a cloned mac address with a connection that does not specify it
We do the same for the original MAC address.

A device enslaved to a bond it inherits the bond's MAC address. When
NetworkManager tries to assume a connection the generated cloned-mac property
causes a mismatch with the connection that originally brought up the device,
causing the generated connection to be used instead:

9aecabe29f config: workaround invocation of "config-changed" signal
There seems to be a bug in glib/ffi that hits on s390x/ppc64 architecture.
It causes @changes in nm-dns-manager.c:config_changed_cb() to be NONE,
although it is clearly set (see the related bug rh #1260577 for glib).

Workaround this, by making the argument type a plain guint.

Note that the ill behavior is caught by test_config_signal() in
"src/tests/config/test-config.c".

5d6b1bce8e config/tests: fix tests after introducing NMExportedObject class
The config-tests contain a NMTestDevice which derives from NMDevice.
However, for testing, it just skips the constructor and destructor of
NMDevice. This caused also the destructors of NMExportedObject to be skipped
and thus valgrind complained about leaked memory.

Fixes: 6fcc1deee0

aadf202cf2 core: add @merge_flags argument to nm_ip4_config_merge() and nm_ip6_config_merge()
The new flags are not yet used, so there is no change in functionality.

The flags NM_IP_CONFIG_MERGE_NO_ROUTES and NM_IP_CONFIG_MERGE_NO_DNS go
together with the 'ignore-auto-routes' and 'ignore-auto-dns' setting.

Note that for IPv4, NM_IP_CONFIG_MERGE_NO_DNS also ignores NIS, WINS, and dns-options.
This is different from current other places that handle 'ignore-auto-dns'
and only care about nameservers, domains, and searches.

b159b668b3 route-manager: add argument to to only remove routes that were added by NMRouteManager
Add an argument @full_sync to the sync method of NMRouteManager.
@full_sync was what we did up to now, meaning, we removed every
route on the interface that was no on our internal list of known
routes.

Now with !@full_sync, only remove routes that were tracked previously.
This means, we will only remove routes that were added by us previously.

Don't make use of the new option yet. So there is no change of behavior
yet.

cce7884fe6 route-manager: always add conflicting direct routes and bump the route-metric if necessary
Kernel does not allow to add the same route (as determined by network/plen,metric)
on two different interfaces (ifindex). In case of conflict, NMRouteManager used to
ignore any but the firstly added route.

On the other hand, we cannot add a gateway-route, if there is no direct
route to the gateway. Hence, skipping duplicate routes can mean that we
skip a direct route what was necessary to add another gateway-route,
which then leads to a failure to add that route.

This also applies to IPv4 device routes that since recently are managed
by NMRouteManager.

For example, say you connect two interfaces to the same IP subnet.
The route-metric can conflict if the interfaces are of the same type
or if the user explicitly configured a conflict.
In case of conflicts, NMRouteManager would only configure the first
appearing route and skip the shadowed route on the second interface.
Now we cannot configure gateway-routes on the second interface because
the gateway is unreachable.

There are many scenarios where this issue can happen, especially with
default-routes and user-configured-routes.
For example with default-routes, ip4_config_merge_and_apply() would check
if the default-gateway requires an explict route and possibly add it.
But then NMRouteManager might not add the route because it is shadowed
by a route on an other interface.

This patch solves the issue by having NMRouteManager configure shadowed
routes too, similar to what NMDefaultRouteManager does.
It does that by searching for an unused, non-conflicting, higher metric
for the route, i.e. bump the metric by 1 until we can add it without
conflict.

Also note that NMRouteManager still ensures that for conflicting routes
the best route sticks to the interface that configured it first. That
means if you later add the conflicting route on another interface, it
will be added with higher metric and the data is still routed along the
first interface.

500f590033 config: only handle 'option+' and 'option-' keys for known settings
It is wrong to blindly merge keys that have an 'option+' or 'option-'.
Merging options is only possibly when we understand what the option
means and how to merge it.

No longer handle every setting but only those that are explicitly known

1b66696f6a config: add NMConfigGetValueFlags argument to nm_config_data_get_value()
In some cases we want the returned value to be stripped. In some cases,
we want to read the raw value instead of the string parsed by GKeyFile.
Add an flags argument to nm_config_data_get_value(). It is up to the caller
to determine the exact meaning (and whether to strip).

By adding the flags argument, the caller can get the desired behavior easier
without having to workaround it afterwards. But more importantly, it becomes
apparent that there are different ways to retrieve the value and the caller
should decide on the details.

14202e10b7 config: fix order of processing [connection] sections in NMConfig
We support the "NetworkManager.conf" sections '[connection]' and
'[connection.\+]' (with arbitrary suffix).

Fix the order of how we evaluate these section.

Note that the literal '[connection]' section is always evaluated lastly
after any other '[connection.\+]' section.

Within one file, we want to evaluate the sections in top-to-bottom
order. But accross multiple files, we want to order them
later-files-first. That gives a reasonable behavior if the user
looks at one file, and also if he wants to overwrite configuration
via configuration snippets like "conf.d/99-last.conf".

Note that if a later file extends/overwrites a section defined in an
earlier file, the section is still considered with lower priority
This is intentional, because the user ~extends~ a lower priority
section. If he wants to add a higher priority section, he should
choose a new suffix.

23d747c77e route-manager: refactor route-manager and route_sync()
Refactor the implementation of nm_route_manager_ip4_route_sync()
and nm_route_manager_ip6_route_sync().

- merge the implementations for IPv4 and IPv6.

- pre-sort the routes and iterate them in a way that we don't
  need to lookup a route in other lists. Do this by iterating
  two sorted lists at a time in a merge-sort way.
  The runtime complexity of sync is now O(n*ln(n)).

- previously, the algorithm would merge routes it found in platform
  to priv->ipx_routes. That was wrong, because then we loose the
  information which routes we wanted to configure internally and which
  are present externally.
  Instead, priv->ipx_routes now contains all the routes that were
  explicitly configured via sync(). Hence, it knows what should be
  configured (@ipx_routes) and can compare to what is configured
  (@plat_routes).

9bd4cf340d core: add NMMultiIndex class
A class to do efficient lookup for multiple values based on a key.

The values are opaque pointers (void*). These values can be
associated with keys. The keys are an opaque type NMMultiIndexId
with arbitrary hash/equal functions.

Think of the keys being a set of buckets. A value can be associated with multiple
keys, just like with a regular GHashTable (i.e. it can be in multiple buckets).
But one key can also be associated with multiple values (i.e. one bucket can contain
multiple values). Hence the name "multi".
One bucket can only either contain a value or not. It cannot contain the same
value multiple times.

This is implemented as a hash of hashes with the outer keys being
NMMultiIndexId. The inner hashes are the "buckets".

This class will be used as an efficient lookup index to find all values
that belong to a certain key (bucket). Later we will ask for example
"Which IP4-Addresses are associated with a certain ifindex" and
efficiently retrieve the cached result list.

a64e81703e config: support a [connection] section to NetworkManager.conf to specify connection defaults
Add support for a new section [connection] in NetworkManager.conf.
If the connection leaves an option at "unknown"/"default", we can
support overwriting the value from global configuration.

We also support other sections that are named with "connection"
as a prefix, such as [connection2], [connection-wifi]. This is
to support multiple default values that can be applied depending
on the used device.

I think this has great potential. Only downside is that when
the user looks at a connection value, it will see that it is
unspecified. But the actually used value depends on the device
type and might not be obvious.

832023fe1c core: add nm_match_spec_split() function
There are currently three device spec properties: 'main.ignore-carrier',
'main.no-auto-default' and 'keyfile.unmanaged-devices'.

The first two, called g_key_file_parse_value_as_string() to split
the string into individual device specs. This uses ',' as separator
and supports escaping using '\\'.

'keyfile.unmanaged-devices' is split using ',' or ';' as separator
without supporting escaping.

Add a new function nm_match_spec_split(), to unify these two behaviors
and support both formats. That is, both previous formats are mostly
supported, but obviously there are some behavioral changes if the string
contains one of '\\', ',', or ';'.

nm_match_spec_split() is copied from glibs g_key_file_parse_value_as_string()
and adjusted.

a01da5f95e core: rework matching of nm_match_spec()
This includes several changes how to match device specs:

- matching the interface name is no longer case-insenstive as
  interface names themselves are case-sensitive.

- Now we skip patterns that start with "mac:" or "s390-subchannels:"
  for comparing interface names. Previously a spec "mac:1" would have
  matched an interface named "mac:1", now it doesn't.
  To match such an interface, you would have to specify
  "interface-name:mac:1".

- previously, a pattern "a" would have matched an interface
  named "interface-name:a", now it doesn't. Since valid interface
  name (in the kernel) can be at most 15 characters long, this is
  however no problem.

- if the spec has the prefix "interface-name:", we support
  simple globbing using GPatternSpec. Globbing without exact
  spec type will still not match "vboxnet*" -- with the exception
  of "*".
  You can disable globbing by putting an '=' immediately
  after the ':'.
     (a) "interface-name:em1"  | matches "em1"
     (b) "interface-name:em*"  | matches "em", "em1", "em2", etc.

41598c1f1a config: move no-auto-default to NMConfigData

modifyable parts migrated to NMConfigData.

Another advantage is that components can now subscribe to
NMConfig changes to pickup changes to no-auto-default.
