Since keyfile uses the connection's ID as the filename by default,
we could run into a situation where two connections with the same
ID are visible to different users. We don't want one connection
overwriting the other in that case, so we need to pick a new name
for one of them. Append the connection's UUID to the end to
minimize the risk of further conflicts for that name.
Duh, AND-ing flags with 0 (which is NM_SETTING_SECRET_FLAG_SYSTEM_OWNED)
is always going to be FALSE... NM_SETTING_SECRET_FLAG_SYSTEM_OWNED is
special; because it's the default value if the key isn't present,
and at this point it's exclusive of all other flags. So (at least for
now) it's OK that it's 0 but we might want to change it later so that
NM_SETTING_SECRET_FLAG_SYSTEM_OWNED can actually be used as a flag.
Now that keyfile is built in, we may have symbol naming conflicts
with the other plugins where code was copied & pasted around. Fix
that by namespacing common function names in the keyfile plugin.
Thanks to Giovanni Campagna for pinpointing the issue.
Since settings storage is now handled by NetworkManager, we must
have the ability to read/write all connection types at all times.
Since the 'keyfile' plugin is the only plugin that can handle all
connection types, build it into NetworkManager.
Keep compat with old format if the SSID includes unprintable
characters. But having to type an int list for an SSID is just silly
and it's about damn time we fix that.
The IO library was in io/ because I was too lazy to find autotools'
SUBDIRS rules at the time and that you could use '.' for the current
directory. Fix that and use its own error defines instead of
the system settings service. Clean up a for more things for good
measure too (like KEYFILE_DIR, etc).
This should help people debug issues with keyfile not recognizing
files since it'll actually print out something when it fails to
parse stuff. Also logs changes, new connections, and deletions.
NMSettingsConnectionInterface was created to allow the daemon and NM
clients to have common code that handled both system and user
connections. It's no longer needed now that user settings services are
gone.
This concludes the flattening of libnm-glib.
The various "update" functions implemented by NMSysconfigConnection have
become confusing. Depending on how you count, we've wound up with about
4 functions that all share the name "update" but nonetheless do
different things. These functions used to be distributed over several
interfaces implemented by NMSysconfigConnection, but now that we've
removed NMExportedConnection and are about to remove
NMSettingsConnectionInterface, they will be all crammed into a single
interface and will be even more confusing than before. It's time to
give better names to these guys.
The renames planned are:
- nm_settings_connection_interface_update() -->
nm_sysconfig_connection_commit_changes()
- nm_sysconfig_connection_update() with signal_update==FALSE -->
nm_sysconfig_connection_replace_settings()
- nm_sysconfig_connection_update() with signal_update==TRUE -->
nm_sysconfig_connection_replace_and_commit()
This commit performs the last two renames. The first will be performed
when removing NMSettingsConnectionInterface.
We also have nm_sysconfig_connection_replace_and_commit() have an
async-ish API that accepts a callback. This fits nicely with the
async-ish API of nm_settings_connection_interface_update(), and it lets
us clean up pk_update_cb() a bit.
NMSettingsInterface was created to allow code to operate on a settings
service without caring about what kind of settings service it was. Now
that we have just one settings service, this is no longer needed.
More work needs to be done in order to handle errors and permission
settings in an appropriate manner.
For exported connections, nm_settings_connection_interface_update() is
supposed to cause the emission of a
NM_SETTINGS_CONNECTION_INTERFACE_UPDATED signal. This is usually done
by chaining up to the NMExportedConnection implementation of this
method, which actually emits the signal. However, the
NMKeyfileConnection implementation usually forgot to do this. Rewrite
so that we always chain up after successfully saving settings.
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.
If the wired setting isn't modified at all from the default values
it won't get written out anymore after 12dcc07b74,
so make sure we include it when necessary.
