Support new bonding options and set them carefully. The options cannot
be set arbitrarily because they interfere with each other.
This commit is forward-ported from rhel-6.5, see patch
rh901662-bond-more-options.patch, originally written by Dan Williams.

Static IP addresses were only read from ifcfg-* file when IP method was
'manual' (BOOTPROTO=none|static). This was to match the legacy initscripts
behaviour. However, NetworkManager supports using additional static IPs in
addition to automatically obtained (DHCP, etc.) addresses. So we now read
static IPs even for automatic methods to be able to use this feature.

When freeing one of the collections such as GArray, GPtrArray, GSList,
etc. it is common that the items inside the connections must be
freed/unrefed too.
The previous code often iterated over the collection first with
e.g. g_ptr_array_foreach and passing e.g. g_free as GFunc argument.
For one, this has the problem, that g_free has a different signature
GDestroyNotify then the expected GFunc. Moreover, this can be
simplified either by setting a clear function
(g_ptr_array_set_clear_func) or by passing the destroy function to the
free function (g_slist_free_full).

ifcfg-rh had the rule that if an ifcfg file had no BOOTPROTO and no
IPv4 addresses, then it should be treated as method=auto for
compatibility. But in fact, current ifup treats it as method=disabled,
so we should too.

Make sure that all connections returned from NMSettings or created via
AddAndActivateConnection have an NMSettingIP4Config and an
NMSettingIP6Config, with non-NULL methods, and get rid of
now-unnecessary checks for those.
Also move the slaves-can't-have-IP-config checks into the
platform-independent code as well. This also gets rid of spurious
"ignoring IP4/IP6 configuration" warnings in ifcfg-rh when reading a
slave ifcfg file.
Partly based on a patch from Pavel.

connection_from_file() requires the 'error' parameter. Not passing a
valid 'error' parameter causes the function to fail and return NULL,
which mean that commit_changes() would always re-write the connection
instead of ignoring commits where nothing has actually changed.
connection_from_file() no longer requires the unmanaged, keyfile,
or routefile parameters, so remove them.
The problem is that there is only a single variable in ifcfg file holding dns
domains - DOMAIN. Thus NetworkManager writes both IPv4 and IPv6 dns-search into
it. While reading there is no way to distinguish between IPv4 and IPv6 values,
so the DOMAIN value is read and only put into IPv4 dns-search.
But, when IPv4 is disabled or invalid, the domains got lost. So in such case
we put DOMAIN variable into IPv6 instead.

Routes without gateway are legal and should be treated as a device route
(direct route).

Since Debian 7 (Wheezy) / Ubuntu 11.04 (Natty Narwhal) ifupdown supports
the source stanza to source in other configuration files from
/etc/network/interfaces.
Add support to the ifupdown plugin to include configuration files via
source.
Patch did not apply cleanly and was slightly modified by Thomas Haller.

This also slighly changes the behaviour for writing IPV6_DEFAULTGW.
- IPV6_DEFAULTGW will be written after IPV6ADDR and
IPV6ADDR_SECONDARY.
- Before, if there were no IPv6 addresse present, the IPV6_DEFAULTGW
might not have been cleared. Now IPV6_DEFAULTGW is always written
(or unset as in the case of gateway ::).

Unfortunately, $(AM_CPPFLAGS) gets overridden by per-target _CPPFLAGS
variables, which $(INCLUDES) did not, so this requires some additional
changes.
In most places, I have just gotten rid of the per-target _CPPFLAGS
variables; in directories with a single target, the per-target
variable is unnecessary, and in directories with multiple targets, the
per-target variable is often undesirable, since it forces some files
to be compiled twice, even though there ends up being no difference
between the two files.
If BOOTPROTO is set to "none", user states that no ipv4 setting should
be set. So respect that.
Introduce helper is_any_ip4_address_defined() along the way to make the
code more readable.

In nm_keyfile_plugin_connection_from_file(), disable the "bad owner"
check.
As root you can read all files anyway, or if necessary even chown them,
and for
other users the standard file permissions will do a fine job.
This fixes running "make check" as root.

Plugins that could save connections to disk previously depended on inotify
events from the kernel to know when to signal connection removal; that is
in response to a 'delete' request they would unlink the backing filesystem
resources, get the inotify signal, and cause NM_SETTINGS_CONNECTION_REMOVED
to be emitted.
Unsaved connections don't have any backing resources, so they would never
get the signal emitted, and NMSettings would never forget about them.
Also, when monitor-connection-files=false in the configuration, obviously
the inotify signals will never come in because they aren't set up.
Given that we can no longer rely on inotify, it's best to just explicitly
send out the NM_SETTINGS_CONNECTION_REMOVED signal whenever a connection
is deleted via the D-Bus interface or internally.
The initscripts do this:
MATCH='^.+\.[0-9]{1,4}$'
if [[ "${DEVICE}" =~ $MATCH ]]; then
VID=$(echo "${DEVICE}" | LC_ALL=C sed 's/^.*\.\([0-9]\+\)/\1/')
PHYSDEV=${DEVICE%.*}
fi
MATCH='^vlan[0-9]{1,4}?'
if [[ "${DEVICE}" =~ $MATCH ]]; then
VID=$(echo "${DEVICE}" | LC_ALL=C sed 's/^vlan0*//')
# PHYSDEV should be set in ifcfg-vlan* file
if test -z "$PHYSDEV"; then
net_log $"PHYSDEV should be set for device ${DEVICE}"
exit 1
fi
fi
which means that if the VLAN name starts with "vlan" then
PHYSDEV must be set, otherwise the parent interface cannot
be determined.
Since PHYSDEV, if set, reflects the explicit intentions of the
user instead of assuming the name from DEVICE, make PHYSDEV
take precedence over determining the parent interface from
heuristics.
A couple functions depended on the passed-in error being !NULL to
correctly report errors, and we can't depend on that because it might
not be true. So fix up those functions' call chain to ensure that
errors get reported regardless of whether 'error' is !NULL.
Bonding options are written straight into [bond] group like:
[bond]
interface-name=bbb
mode-active-backup
miimon=300
So we have to handle them explicitly.
We have to copy the UUID (key) because otherwise the pointer can be invalidated
when the connection is destroyed and problems will start.
The issue showed up as an unability to delete a conenction via D-Bus.
Reproducer:
$ nmcli con add type eth con-name AAA ifname blah
$ nmcli con delete AAA
$ nmcli con add type eth con-name AAA ifname blah
$ nmcli con delete AAA
-- here the connection is not removed from NM
(even though ifcfg- file) was removed --
Add a "monitor-connection-files" config option, which can be set to
"false" to disable automatic reloading of connections on file change.
To go with this, add a new ReloadConnections method on
o.fd.NM.Settings that can be used to manually reload connections, and
add an nm-cli command to call it.
Some plugins may emit :new-connection or :unmanaged-specs-changed
while reading connections, so don't connect to those signals until
after the initial load_connections() (and just unconditionally emit
:unmanaged-specs-changed at that point).
In ifcfg-rh's get_unmanaged_specs(), don't bother to try to read the
connections first; if they haven't been read yet, just return NULL;
NMSettings will call it again after the connections have been read.
