NMExportedConnection originally implemented its DBus method call
handlers as virtual functions, primarily so that system and user
settings services could implement them differently.
NMIfupdownConnection also depended on GetSecrets being virtual, so this
was retained when NMExportedConnection was flattened into
NMSysconfigConnection.
However, it turns out that NMIfupdownConnection doesn't really need
these functions to be virtual; it's more appropriate to override the
methods of NMSettingsConnectionInterface (which are used by the DBus
handlers). Indeed, we really don't want settings plugins to override
the DBus handlers, as we must authorize the caller before doing anything
else. So we can save a bunch of code and devirtualize these handlers.
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.
In continuation of the theme, the removal of user settings services
means that the distinction between NMSysconfigConnection and
NMExportedConnection is no longer needed. Merge NMExportedConnection
into NMSysconfigConnection.
Much as with nm-remote-settings and nm-remote-settings-system, the
removal of user settings services means there is no more need for
separate interfaces for user and system settings services.
In libnm-glib, this commit merges everything in
nm-settings-system-interface into nm-settings-interface. Alongside with
that, we merge everything in the
org.freedesktop.NetworkManagerSettings.System DBus interface into
org.freedesktop.NetworkManagerSettings.
Now that we have only one settings service, there is no more need to
have common settings service code in libnm-glib. So we can simplify
things somewhat my moving everything from nm-settings-service into
nm-sysconfig-settings.
Remove code related to "connection scope" and such. Later, we will also
do lots of code flattening and simplification that's possible now that
user settings are gone.
Remove all references to connection scope and user-settings services
from the various internal APIs of the daemon. The external DBus API
remains unchanged, albeit in stub form for scope stuff.
It turns out that user settings services are strange and complicated
beasts. We will remove support for them, and we will later implement
security mechanisms on the system settings service that will do what
user settings services were intended to do.
This commit is a bulk removal of nm-manager's internal support code for
user settings services. The external API is largely unchanged, but
errors are returned if anyone ties to do something with user settings.
Work remaining includes some possible flattening of nm-manager's
internal code, along with code removal and API changes in other modules.
If the client was disabled with --with-dhclient=no or
--with-dhcpcd=no, then it's corresponding _PATH will be an empty
string. In that case we want to ignore that client completely
since it was disabled at build time.
The wifi device is considered to be 'scanning' if the supplicant emits
the scanning signal or if it's in the scanning state; but the code
didn't correctly handle notifications when the supplicant was in the
scanning state.
This reverts commit b172519045.
When something like NTP updates the system clock, that can cause
dhclient to expire the lease, and at that point we just want NM
to let dhclient re-aquire the lease instead of failing the
whole connection.
Even though we prefer NetworkManager.conf, we need to check the
old nm-system-settings.conf first to preserve compat with older
setups. In package managed systems dropping a NetworkManager.conf
onto the system would make NM use it instead of nm-system-settings.conf,
changing behavior during an upgrade. We don't want that.
The PPP setting will usually be all defaults anyway, so lets just
created it when needed if it doesn't yet exist. Fixes an error
where the connection editor couldn't edit system DSL connections
because it tried to request secrets for the PPP setting that didn't
actually exist in the connection because the 'keyfile' plugin
wouldn't save all-default settings, thus that setting wouldn't
exist when read back in.
Some proprietary drivers (wl.o) report tuned frequency (like when
scanning) instead of the associated AP's frequency. This is a great
example of how WEXT is underspecified. We use frequency to find the
active AP in the scan list because some configurations use the same
SSID/BSSID on the 2GHz and 5GHz bands simultaneously, and we need to
make sure we get the right AP in the right band. This configuration
is uncommon though, and the frequency check penalizes closed drivers we
can't fix. Because we're not total dicks, ignore the frequency condition
if the associated BSSID/SSID exists only in one band since that's most
likely the AP we want.
Monitor the kernel firmware directory (set at configure-time with
--with-kernel-firmware-dir=<path>) for changes, and if there
are any, try bringing up devices that are missing firmware.
Not all drivers will return errors when even when they don't provide
the GPERMADDR ethtool call; sometimes you'll get 00:00:00:00:00:00
which is clearly not right. In this case, fall back to the current
HW address just like if the ethtool GPERMADDR call failed.
- Just use a byte array to old MAC addresses so we don't need to
use .ether_addr_octet everywhere
- Consolidate setting the current MAC address into one location
- Make sure that if the GPERMADDR call fails we use the current MAC
(this wasn't done for wired devices)
- Make log messages consistent
