If, for example, a bond interface has dynamic IPv4 configuration
and static IPv6 configuration, then without slaves IPv6 config
can proceed but IPv4 cannot until a slave is present. Allow
subclasses to postpone a specific IP configuration path until
they're ready, but let others proceed.
We don't need to check device state here because the manager, which
is the only thing that calls nm_device_activate() in
internal_activate_device() ensures that the device is deactivated
before starting a new activation request.
Allows to attach any connection to a bridge using the BRIDGE= key.
IP configuration is optional for bridge components but not
prohibited. Test case included.
Provides functions to create and delete bridging devices and
to attach/detach slaves from bridging devices.
It currently relies on the ioctl() kernel interface. The long
term goal is to use the netlink interface for this.
This function gets used for both /proc/sys (ie, sysctl) and for
sysfs attributes. There are two issues with it:
1) most sysctl values don't care about a trailing LF, but some
sysfs attributes (infiniband) do; so we always have to add the
trailing LF. Just move that into the function to ensure that
callers don't forget to add it.
2) neither sysfs or sysctl support partial writes, while the
existing function did partial writes. Practically, both the
write handlers for sysfs and sysctl should always handle all
the data, but if they don't, partial writes are wrong. So
instead, try three times to write all the data.
Can't leave the backup files lying around when doing 'make distcheck',
so when backup up a file, return the backup file path so that the
caller can (optionally) remove it.
If the certificate path from the supplicant config is not absolute,
we need to make it absolute. When building with a different builddir,
the certificate from the supplicant config is actually in the srcdir,
but the builddir is the current PWD.
Recent automake versions switched to not creating empty directories,
but at the moment NetworkManager g_warning()s on startup if it doesn't
find $(pkglibdir). So let's make it.

(core: move DNS change handling to the policy and optimize DNS updates (bgo #676778))
It consolidated DNS update handling, but mistakenly removed hostname changing
from NM_DEVICE_STATE_ACTIVATED state handler.

When enumerating devices, libgudev's matching by default will return
devices which udev has not yet finished initializing.
This was frequently causing boot-time races on the OLPC XO, where
NetworkManager would bring a device up before udev had renamed it,
causing the later rename to fail.
To solve this, filter the enumeration matches to only include
initialized devices. The devices that are present but uninitialized
at this time will arrive a short time later, via a uevent.

(dcbw: update gudev version check in configure.ac)
Until we remove libnl-1.x and libnl-2.x support, it should be
possible to choose the libnl version at build time. This is
mostly important for testing legacy libnl support but it also
helps distributions that ship other tools built agains them.

Instead of a 'modem#' identifier, use the primary port of the modem as unique
identifier. The modem UID will be set afterwards as the Device Iface, which is
then used by libnm-glib to gather vendor/product string from the udev device
associated with the Device Iface; so it really needs to be a real port.
Trying to ARP with no other machines in the broadcast domain
is pretty pointless, and in many cases doesn't work (ZTE MF691
/T-Mobile Rocket 2), so turn it off.
The only case where this was being used was in PPP-based connections, as the
ppp0 interface was reported by pppd once the IP setup was done. Instead, just
update the 'NM_MODEM_DATA_PORT' property, as the NMDevices already listen for
changes in that property.
The new ModemManager1-based `NMModemBroadband' objects will set the data port
information only after having created the bearer as part of the connection
process. The devices, therefore, need to listen to changes in the `data-port'
property, so that the `ip-iface' in the `NMDevice' is set before finishing the
stage1 of the activation. This is required in order to have a proper ifup of the
data port.
G_TYPE_INSTANCE_GET_PRIVATE() is known to be slow, so just call it once when
the private data is created, and keep a 'priv' pointer around for easy access.
The new `MMManager' object takes care of notifying modems added or removed from
the ModemManager1 interface.
We will listen to both the old and new ModemManager implementations, but as soon
as the first ModemManager implementation is found, the other one gets cleared,
so that we don't wait forever to appear.
The new ModemManager comes with its own headers, and defines its own symbols to
name e.g. each interface. In order not to collide with the new ones, rename the
existing ones with a 'MM_OLD_DBUS' prefix instead of just 'MM_DBUS'.
Previously, when a new bond or VLAN connection was created, NM would
always create the virtual device right away. But on startup, it only
creates virtual devices for connections that can autoconnect. Fix
connection_added() to make that check as well.
This patch makes DHCPv6 support more or less equivalent to that
one of IPv4 DHCP.
(dcbw: fix some formatting, rearrange code so it's less convoluted,
fix up writing hostname to ifcfg files)
For NetworkManager, dhclient is a runtime dependency. Distribution dhclient
configuration is either put directly into /etc or in /etc/dhcp. It is much
safer to check this at runtime than to guess the location from distribution
name.
Additionally, the distribution dhclient configuration files can be overriden
by a configuration file in /etc/NetworkManager.
TODO: Functions get_dhclient_config() and merge_dhclient_config() should
be also used for IPv6.
DHCP lease file names are built by NetworkManager and contain connection UUID
which makes them NM-specific. Their new location belongs to NetworkManager and
doesn't have to be guessed. With no guessing, we don't need distribution-specific
conditionals.
Note: This change may require modifications to the selinux policy. But after all
these files actually belong to NetworkManager as well as the instance of dhclient
that uses them.
Use --enable-doc and --enable-tests instead of --with-docs and
--with-tests. This is consistent with other features and with
--enable-gtk-doc option. Support current variants as fallback.
Don't build tests unless --enable-tests is specified.
You can now use 'address=' even for IPv6 and it's the encouraged way
to set up a single address manually. For multiple addresses,
'address0=', 'address1=', etc, should be preferred.
Example:
address=10.0.0.15/24/10.0.0.1
address0=192.168.0.1/24
address1=10.0.0.16/32
Example (backward compatibility):
addresses=10.0.0.15/24/10.0.0.1
addresses0=192.168.0.1/24
addresses1=10.0.0.16/32
IPv4 and IPv6 address configuration is now handled together and supports
the following syntax (slashes can be replaced with semicolons):
address/plen
address/plen,gateway
IPv4 and IPv6 route configuration is also handled uniformly and supports
the following syntax:
address/plen (for device routes)
address/plen,gateway (for gateway routes)
address/plen,gateway,metric (for gateway routes with metric)
For compatibility reasons, slash (/), comma (,) and semicolon (;) are
considered equal by the parser. The /plen part is optional for both
addresses and routes for compatibility reasons.
Leaving out the prefix length is not considered a good idea. IPv6
addresses default to 64 and IPv4 now defaults to 24 which is the closest
possible IPv4 counterpart. Routes default to single addresses.
Example 1:
[ipv4]
method=manual
addresses1=192.168.56.5/24,192.168.56.1
addresses2=192.168.57.5/24
routes1=4.5.6.0/24
routes2=1.2.3.0/24,4.5.6.7
routes3=7.8.9.0/24,4.5.6.7,99
[ipv6]
method=manual
addresses1=2001:db8:a🅱️:3/64,2001:db8:a🅱️:1
addresses2=2001:db8:c:d::3/64
routes1=2001:db8:e:f::/64,2001:db8:a🅱️:4
Example 2 (equivalent):
[ipv4]
method=manual
addresses1=192.168.56.5;24;192.168.56.1
addresses2=192.168.57.5;24
routes1=4.5.6.0;24
routes2=1.2.3.0;24;4.5.6.7
routes3=7.8.9.0;24;4.5.6.7;99
[ipv6]
method=manual
addresses1=2001:db8:a🅱️:3;64;2001:db8:a🅱️:1
addresses2=2001:db8:c:d::3;64
routes1=2001:db8:e:f::;64;2001:db8:a🅱️:4
For writing, I have arbitrarily chosen one of the formats 'reader'
can parse. Address and prefix length are separated by slash (/),
everything else is separated by comma (,).
addresses1=address/plen,gateway
routes1=address/plen,gateway,metric
Note: The modified 'reader' exposes a bug in the 'writer' and ignores
out badly-formatted routes. This problem is also fixed by this
commit. Keyfile tests now pass.
