There is no general purpose file for platform utilities.
We only have nm-platform.h, which contains (mostly) functions
that operate on a NMPlatform instance (and that can be mocked
using NMFakePlatform).
Add a new file for independent utility functions. nm-platform-utils.c
should not call into functions having a NMPlatform instance, to
have them independent from platform caching and the platform
singleton.
(cherry picked from commit ce700d94f5)
nm_platform_query_devices() would raise an 'added' signal
for all its links. That is bad style because it could
confuse other listeners for platform signals which don't
expect such artificial change signals.
The public API of NMPlatform already gives NMManager the ability
to 'pull' all the links and iterate them itself.
Before, nm_platform_query_devices() would also initialize udev
devices, so there was a more compelling reason for this function.
(cherry picked from commit d7a312d17a)
We already populate the netlink cache in constructed(). No need
to wait with udev devices until nm_platform_query_devices(). Just
do it right away.
Add a hack to keep 'lo' default-unmanaged. Now that we load
udev devices earlier, we end up clearing the default-unmanged
flag on 'lo', which has bad consequences.

We don't want error logging for nm_platform_link_add() which
tries to load the bonding module. Later we will run tests as non-root,
where modprobe will fail. Logging an error would break the tests.
(cherry picked from commit 39f2b51abb)
We already have "nm-utils*.h" and "NetworkManagerUtils.h" headers. Rename
"include/nm-utils-internal.h" to "nm-macros-internal.h". I think that
name is better, because this file is header-only, internal, and
repository-wide.
Also, it will never contain non-header-only declarations because
there is no backing object file under "include/".
It will only contain macros and inline functions.

AUTOCONNECT_SLAVES is an NetworkManager extension. initscripts always activate
slaves with the master connection for bond and team, and doesn't activate
automatically slaves for bridge.
NetworkManager behaviour is controlled by this variable. If the variable is
missing the default value from configuration file is used.
(cherry picked from commit 2a497eeadc)
Since introduction for support of ip6-privacy (use_tempaddr,
RFC4941) with commit d376270bfe,
the sysctl value from /etc was always read first.
This is problematic, because an explicit setting in the
connection should not be ignored over a global configuration.
Drop that old behavior. It was also problematic, because we did
not read any files under /etc/sysctl.d (except for sysctl.conf).
Also, we did not honor per-interface configurations.
Now we also use as last fallback the value from
/proc/sys/net/ipv6/conf/default/use_tempaddr
That has the advantage of falling back to the system default value
so that NM doesn't need to have it's own default policy
(Related: https://bugzilla.redhat.com/show_bug.cgi?id=1187525).
This is a change in behavior.
(cherry picked from commit f3c61f8141)
Support default value for setting 'ipv6.ip6-privacy' in
NetworkManager.conf.
If the global value is unset, preserve old behavior of looking into
/etc/sycctl.conf first. That behavior was introduced with commit
d376270bfe, since we support ip6-privacy
setting.
If the global value is set to "unknown", add a new fallback
that instead reads the runtime value from
"/proc/sys/net/ipv6/conf/default/use_tempaddr"
This seems more sensible behavior because we fallback to sysctl,
but instead of looking at static files in /etc, read /proc.
But to preserve the old behavior, we only do that when a global
value is configured at all.

(cherry picked from commit e729dd70ae)
The route-metric can be configured per connection via the
ipv4.route-metric and ipv6.route-metric fields. When the
value is left at -1 (the default), we would determine the
route-metric based on the device type (nm_device_get_priority()).
Extend that scheme by making the default value overwritable in
NetworkManager.conf.
(cherry picked from commit 59a991725a)
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.

Support a device-spec to match by device-type.
This matches on the value as shown by
nmcli -f GENERAL.TYPE device show
(cherry picked from commit 3fb60edf9f)
Add a function to get a concise representation of the
device type.
libnm already has nm_device_get_type_description() for that
and it is shown by
nmcli -f GENERAL.TYPE device show
Reimplement that function for nm-core. Just take care that the
two implementations don't diverge.

In case of error, ibft prints an error message to stderr
with two trailing newlines. This causes multiple lines
in our logfile. Replace newlines in the error message
by whitespaces.

Before, the Wi-Fi plugin was always build. Users who didn't want
to use it would simply drop "libnm-device-plugin-wifi.so".
Add a compile time option to disable needlessly building the plugin.

The Interface held a reference to the manager to listen for the 'available'
signal. Instead of that, let's make the child unaware of the master to
keep the inheritance cleaner.

The user-requested reason is not really appropriate and blocks autoreconnect.
We added a new reason precisely for that.

Add a netlink implementation for reading InfiniBand properties, but fall back to
sysfs when that isn't supported by the kernel.
(cherry picked from commit 5cf226463a)
We need to know whether we can create interfaces of any given
NMDevice subclass or not. So don't rely on just the NMPlatformLink
for that information, because we won't have a platform link for
software devices before we create them.
(cherry picked from commit d4e0a1e8cc)
We can't have devices with duplicate interface names so we might
as well use that for dupe checking instead of the (mostly useless)
UDI.

We'd be able to do so for already existing devices, but not for devices that
are added afterwards, since gudev is hardwired not to listen for events from
kernel.
(cherry picked from commit 26aeb12749)
Mount a private sysfs instance. Otherwise gudev sees the devices from the
parent netns as opposed to our netns.
We do, however need a writable /sys/devices subtree for testing the bridge
code. There doesn't seem to be any other way to get a writable subtree of a
read-only filesystem than remounting it with no parameters after the initial
mount. We use this to get a writable sysfs instance and then bindmount it so
that it fits properly in the sysfs hierarchy.
