For those ifcfg files that do have HWADDR and thus can have their
device be unmanaged, we want to read in a much of the connection as
possible since unmanaged devices are tracked via internal NMIfcfgConnection
objects. For BRIDGE/VLAN ifcfg files that don't have HWADDR, we do
want to ignore them completely, but also return a useful error
message.
Previously the code would assume that if the ifcfg file had no backing
connection that we should try to read it in regardless of what the
inotify event was. But if the event was DELETED, there's no point in
trying to read a deleted file in; it's gone. Don't print bogus
warnings about failure to read the long-gone ifcfg file.
Kind of a hack for now, would be better to push down a flag about
whether the update request came in from D-Bus, internally, or from
inotify, but that's a lot more invasive.
Treat them as unmanaged for now so that they dont' need NM_CONTROLLEd=no
which would require further configuration when NM does start to support
these configs.
There are so many... so handle them as a table of key/value pairs
instead of having separate functions for each one. At the moment
nothing but subchannels is used internally, but this allows plugins
to preserve options that NM doesn't care about when reading/writing
system configuration.
This commit implements MAC cloning feature in NetworkManager. To support that,
'PermHwAddress' property is added into *.Device.Wired and *.Device.Wireless
interfaces. The permanent MAC address is obtained when creating the device, and
is used for 'locking' connections to the device. If a cloned MAC is specified
in connection to be activated, the MAC is set to the interface in stage1. While
disconecting, the permanent MAC is set back to the interface.
ifcfg-rh plugin didn't prepend 's:' prefix when writing out ASCII WEP
keys. That rendered the keys file invalid. Moreover, the reading part
was incorrect too not having recognized correct ASCII keys.
All IPv6 enabled sites are expected to provide router advertisement
support apparently. If standalone DHCP is really used in the wild
then we can clearly re-enable it later.
ifcfg-rh wasn't updated for WEP passphrases after that capability
got added. Can't use KEY for passphrases since there's no way
to distinguish some WEP passphrases from some WEP Hex and ASCII
keys, so we use KEY_PASSPHRASE instead.
Instead of not including the IP4 setting, set its method to disabled.
In reality either one is legal, but including the IP4 setting wtih
the method set to 'disabled' is more explicit.
ifcfg-rh plugin was not able to reset MTU to "automatic" if it had been
set to a value, for wired connection. This fix removes "MTU" variable
from the ifcfg-* file when mtu is 0.
ifup/ifdown, nmcli, and possibly other tools need a way to get the
internally generated connection UUID and possibly it's path given
just the ifcfg file path. Not all ifcfg files have the UUID in
the file, so ifcfg-rh generates one. But external tools don't know
what that UUID is or what the logic that NM uses to generate it is.
Help them out a bit so that ifup/ifdown can easily poke NM given
just the ifcfg file.
