We repeatedly call nm_device_update_hw_address() to reset the cached
MAC address of the device. However, we don't allow changing the address
length once it is set.
Multiple entities (initial, current and permanent MAC address) are all
checked to have the same address length. Changing the length would be a
very strange thing (and probably indicate a bug somewhere else).
Just don't allow that.
On devices that have no real permanent hardware address (as returned
by ethtool), we take the current MAC address of the device.
Currently, NM is a bit flaky about whether to accept such fake permanent
addresses for settings like keyfile.unmanaged-devices or the per-
connection property ethernet.mac-address. Probably, we should allow
using fake addresses there in general.
However, that leads to problems because NetworkManager itself changes
the current MAC address of such devices. For example when
configuing
keyfile.unmanaged-device=22:33:44:55:66:77
and later activating a connection with
ethernet.cloned-mac-address=22:33:44:55:66:77
we have a strange situation after restart and the device becomes
unmanaged.
We are going to avoid that, by remembering the fake permanent address
in the device state file.
This only matters:
- for devices that don't have a real permanent address (veth)
- if the user or NetworkManager itself changed the MAC address
of the device
- after a restart of NetworkManager, without reboot. A reboot
clears the device state for /var/run/NetworkManager.
_nm_utils_hwaddr_length() did a validation of the string
and returned the length of the address. In all cases where
we were interested in that, we also either want to validate
the address, get the address in binary form, or canonicalize
the address.
We can avoid these duplicate checks, by using _nm_utils_hwaddr_aton()
which both does the parsing and returning the length.
nm_settings_connection_set_autoconnect_blocked_reason() must be called
on the settings-connection. Fixes the following:
GLib-GObject-WARNING **: invalid cast from 'NMSimpleConnection' to 'NMSettingsConnection'

We only needed proper glib enum types for having properties
and signal arguments. These got all converted to plain int,
so no longer generate such an enum type.
Had to rename "nm-enum-types.h" because it works badly with
"libnm/nm-enum-types.h". Maybe I could fix that differently,
but duplicate names is anyway error prone.
Note that "nm-core-enum-types.h" is already taken too, so
"nm-src-enum-types.h" it is.
We should enable tests by default, probably we even should drop
the configure flags to enable tests and just always build them.
Anyway, at this point there is no use in guarding check-local
with a check for ENABLE_TESTS. A user who does't want to run
the tests, should just not call `make check`.
Internal device types are a static thing. Let's not do a
constructor function to register the device factory.
This gets rid of all attribute((constructor)) functions inside
NetworkManager core. That is desired, because we don't want to
run code before main(). For example, at that point logging is
not yet initialized, but with code that runs before main() it
is hard to ensure that we don't log anything yet.
An interface would make sense to allow the actual device-factory to inherit
from another type.
However, glib interfaces make code much harder to follow and less
efficient. The device factory shall be a very simple type with meta data
about supported device types and the ability to create device instances.
There is no need to make this an interface implementation, instead just
let the factories inherit from NM_TYPE_DEVICE_FACTORY directly.
The default wired connection is already generated allowing the use of a fake
address, but for the state file and the device matching specs only non-fake
addresses are used. Let's allow fake addresses consistently, so that default
wired connections work properly in containers (where the veth address is
considered fake) as well.
Also, it would really be a better idea to use ifnames everywhere instead, but
that would change the format of the state file.
All callers of request_wireless_scan() cleared the periodic scan
source immediately before calling the function, so just move that
into request_wireless_scan(). The only one that doesn't clear
it is request_wireless_scan_periodic() but that sets the source
id to 0 already, so the clear has no effect.

Some TTY drivers or devices appear to ignore port speed and always
report zero. Technically this means the port is hung up and control
lines should be disconnected, but with USB devices many of the serial
port attributes are meaningless and ignored by some devices.
pppd requires the port's speed to be greater than zero, and will
exit immediately when that is not the case, even though these
modems will work fine. Passing an explicit speed to pppd in this
case works around the issue, as pppd attempts to set that speed
on the port and doesn't actually care if that operation fails.

First of all, G_LOG_DOMAIN only matters when using g_log() directly.
Inside core, we always want to log via nm-logging. Every call to a
g_log() is a bug in the first place (like a failed assertion that logs
a g_critical() during g_return_if_fail()).
So, for all practic purposes, the logging domain is not used.
For nm-logging, the G_LOG_DOMAIN has no effect. Unless we find a proper
use of this domain, G_LOG_DOMAIN should not differ from what the rest of
core.
NMAccessPoint was in file "nm-wifi-ap.h" with
method nm_ap_*(). Make the naming consistent.
Also rename "nm-wifi-ap-utils.*" as it contains general
purpose wifi utilities. No need to have special "ap" utilities.
Same for "test-wifi-ap-utils.c". It just contains general wifi
tests.
The names NMPacRunnerManager, nm_pac_runner_manager were inconsistent
with NM_PACRUNNER_MANAGER and nm-pacrunner-manager.[hc]. They should
be consistent.
It seems pacrunner project calls itself "PACrunner" or just "pacrunner",
so prefer the spelling with lower-case 'r'.
As the type is called NMPacRunnerManager, the proper name for the
functions is nm_pac_runner_manager*(). Alternatively, it the type
should be NMPacrunnerManager.
nm_pacrunner_manager_send() would only fail if passed in a NULL proxy_config.
And then it would log a <info> message without details about what failed.
Just don't do that.
src: Fixes in nm-device.c and nm-vpn-connection.c to update PacRunner
at the right place and moment. When a device goes up PacRunner is
configured with the Device IPxConfigs and Proxy Config. When it goes
down the same configuration is removed from PacRunner.
ifcfg-rh: Fixed to read and write proxy settings to the ifcfg network
scripts.
- use _NM_GET_PRIVATE() and _NM_GET_PRIVATE_PTR() everywhere.
- reorder statements, to have GObject related functions (init, dispose,
constructed) at the bottom of each file and in a consistent order w.r.t.
each other.
- unify whitespaces in signal and properties declarations.
- use NM_GOBJECT_PROPERTIES_DEFINE() and _notify()
- drop unused signal slots in class structures
- drop unused header files for device factories
