config.h should be included from every .c file, and it should be
included before any other include. Fix that.
(As a side effect of how I did this, this also changes us to
consistently use "config.h" rather than <config.h>. To the extent that
it matters [which is not much], quotes are more correct anyway, since
we're talking about a file in our own build tree, not a system
include.)
The gateway is a global property of the IPv4/IPv6 configuration, not
an attribute of any particular address. So represent it as such in the
API; remove the gateway from NMIPAddress, and add it to
NMSettingIPConfig.
Behind the scenes, the gateway is still serialized along with the
first address in NMSettingIPConfig:addresses, and is deserialized from
that if the settings dictionary doesn't contain a 'gateway' key.
Adjust nmcli's interactive mode to prompt for IP addresses and gateway
separately. (Patch partly from Jirka Klimeš.)
Split a base NMSettingIPConfig class out of NMSettingIP4Config and
NMSettingIP6Config, and update things accordingly.
Further simplifications of now-redundant IPv4-vs-IPv6 code are
possible, and should happen in the future.
Merge NMIP4Address and NMIP6Address into NMIPAddress, and NMIP4Route
and NMIP6Route into NMIPRoute. The new types represent IP addresses as
strings, rather than in binary, and so are address-family agnostic.

The first test case assumes the child does not go away immediately after being
delivered a TERM signal. Add some delay to its teardown code path, so that NM
will set up the timeout the test expects.
Add nm-core-types.h, typedefing all of the GObject types in
libnm-core; this is needed so that nm-setting.h can reference
NMConnection in addition to nm-connection.h referencing NMSetting.
Removing the cross-includes from the various headers causes lots of
fallout elsewhere. (In particular, nm-utils.h used to include
nm-connection.h, which included every setting header, so any file that
included nm-utils.h automatically got most of the rest of libnm-core
without needing to pay attention to specifics.) Fix this up by
including nm-core-internal.h from those files that are now missing
includes.
Instead of creating it in NMSettings, where we must use
NM_IS_DEVICE_ETHERNET() (not NM_DEVICE_TYPE_ETHERNET because various generic
devices masquerade as NM_DEVICE_TYPE_ETHERNET too), push knowledge
of which device types create default wired connections into the device
types themselves. This solves a problem with testcases where
libNetworkManager.a (which testcases link to) requires the symbol
nm_type_device_ethernet().
Change all DBUS_TYPE_G_LIST_OF_STRING and DBUS_TYPE_G_ARRAY_OF_STRING
properties to G_TYPE_STRV, and update everything accordingly.
(This doesn't actually require using
_nm_setting_class_transform_property(); dbus-glib is happy to transform
between 'as' and G_TYPE_STRV.)
The fact that NMRemoteConnection has to be an NMConnection and
therefore can't be an NMObject means that it needs to reimplement bits
of NMObject functionality (and likewise NMObject needs some special
magic to deal with it). Likewise, we will need a daemon-side
equivalent of NMObject as part of the gdbus port, and we would want
NMSettingsConnection to be able to inherit from this as well.
Solve this problem by making NMConnection into an interface, and
having NMRemoteConnection and NMSettingsConnection implement it. (We
use some hacks to keep the GHashTable of NMSettings objects inside
nm-connection.c rather than having to be implemented by the
implementations.)
Since NMConnection is no longer an instantiable type, this adds
NMSimpleConnection to replace the various non-D-Bus-based uses of
NMConnection throughout the code. nm_connection_new() becomes
nm_simple_connection_new(), nm_connection_new_from_hash() becomes
nm_simple_connection_new_from_hash(), and nm_connection_duplicate()
becomes nm_simple_connection_new_clone().
Previously, src/nm-ip4-config.h, libnm/nm-ip4-config.h, and
libnm-glib/nm-ip4-config.h all used "NM_IP4_CONFIG_H" as an include
guard, which meant that nm-test-utils.h could not tell which of them
was being included (and so, eg, if you tried to include
nm-ip4-config.h in a libnm test, it would fail to compile because
nm-test-utils.h was referring to symbols in src/nm-ip4-config.h).
Fix this by changing the include guards in the non-API-stable parts of
the tree:
- libnm-glib/nm-ip4-config.h remains NM_IP4_CONFIG_H
- libnm/nm-ip4-config.h now uses __NM_IP4_CONFIG_H__
- src/nm-ip4-config.h now uses __NETWORKMANAGER_IP4_CONFIG_H__
And likewise for all other headers.
The two non-"nm"-prefixed headers, libnm/NetworkManager.h and
src/NetworkManagerUtils.h are now __NETWORKMANAGER_H__ and
__NETWORKMANAGER_UTILS_H__ respectively, which, while not entirely
consistent with the general scheme, do still mostly make sense in
isolation.
Include <linux/if_ether.h> and <linux/if_infiniband.h> from
nm-utils.h, to get ETH_ALEN and INFINIBAND_ALEN, and remove those
includes (as well as <net/ethernet.h> and <netinet/ether.h>, and
various headers that had been included to get the ARPHRD_* constants)
from other files where they're not needed now.
Drop the arptype-based nm_utils_hwaddr funcs, and rename the
length-based ones to no longer have _len in their names. This also
switches nm_utils_hwaddr_atoba() to using a length rather than an
arptype, and adds a length argument to nm_utils_hwaddr_valid() (making
nm_utils_hwaddr_valid() now a replacement for nm_utils_hwaddr_aton()
in some places, where we were only using aton() to do validity
checking).
Add NetworkManager.h, which includes all of the other NM header, and
require all external users of libnm to use that rather than the
individual headers.
(An exception is made for nm-dbus-interface.h,
nm-vpn-dbus-interface.h, and nm-version.h, which can be included
separately.)
Since the API has not changed at this point, this is mostly just a
matter of updating Makefiles, and changing references to the library
name in comments.
NetworkManager cannot link to libnm due to the duplicated type/symbol
names. So it links to libnm-core.la directly, which means that
NetworkManager gets a separate copy of that code from libnm.so.
Everything else links to libnm.

Some subdirectories of src/ encapsulate large chunks of functionality,
but src/config/, src/logging/, and src/posix-signals/ are really only
separated out because they used to be built into separate
sub-libraries that were needed either for test programs, or to prevent
circular dependencies. Since this is no longer relevant, simplify
things by moving their files back into the main source directory.
Clean up some of the cross-includes between headers (which made it so
that, eg, if you included NetworkManagerUtils.h in a test program, you
would need to build the test with -I$(top_srcdir)/src/platform, and if
you included nm-device.h you'd need $(POLKIT_CFLAGS)) by moving all
GObject struct definitions for src/ and src/settings/ into nm-types.h
(which already existed to solve the NMDevice/NMActRequest circular
references).
Update various .c files to explicitly include the headers they used to
get implicitly, and remove some now-unnecessary -I options from
Makefiles.
5b4be27f moved test-dhcp-options from src/tests/ to
src/dhcp-manager/tests/, but src/tests/Makefile.am still included it
in "TESTS" (which would still work until you tried to build from a
clean tree...)
Previously the tests required that a NMDHCPClient object was
created, but all that's really being tested is the DHCP option
parsing and that doesn't need a client object now that the
option parsing has been split out.
Also, the options test wasn't in src/dhcp-manager/, so put it there.
Lastly, the test ran for both dhclient and dhcpcd, but the code
executed for both cases was the same, so there's no reason to keep
running the test for both clients.
nm-version.h was getting disted, making srcdir!=builddir work for
tarball builds, but not for git builds.
Also, remove "-I${top_builddir}/include" from all Makefile.ams, since
there's nothing generated in include/ any more.
Some tests want to assert against the messages logged using g_test_expect_message().
In this mode, nmtst will not log anything itself.
Interpret the option no-expect-message which turns g_test_expect_message()
into a NOP and turns logging on. The use of this is for debugging such
tests, without asserting against the messages but printing them instead.
For tests that are not in the assert_message mode, the option has no
effect.
Example:
NMTST_DEBUG=debug,no-expect-message make -C src/settings/plugins/keyfile/tests/ check

In this mode, nmtst itself will not log anything and not set the logging
level. Also, it will set g_log_set_always_fatal().
This is for tests that want to assert against all logged messages via
g_test_expect_message().
In this mode also setting the logging level via NMTST_DEBUG variable has
no effect. The test is expected to manage the logging level itself and
changing the logging level might interfere with the test.
As a showcase, move keyfile/tests/test-keyfile.c to nmtst.
