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.

Our internal copy of systemd should not be in the search path.
Instead, let users only
#include "systemd/nm-sd.h"
which then includes everything from systemd that we need.
We want to avoid to accidentally include anything from our
systemd-copy. Any user of that should only include "nm-sd.h",
which then includes everything that is needed further.
For example, "src/devices/wwan/nm-modem-manager.c" has
#include <systemd/nm-daemon.h>
which in turn includes
#include "_sd-common.h"
This works all correctly before, because #include "" will first
look in the directory where sd-daemon.h is. However, our mixing of
external systemd library and internal copy is rather dangerous.
Try to avoid it further by keeping the include paths clean.
NMPolicy:auto_activate_device() would wrongly not free the
specific_object, although it is documented as transfer-full.
The only implementation of can_auto_connect() that returned
a specific-object is NMDeviceWifi:can_auto_connect(). So, there
wasn't any actual bug or memory leak.

No need for the setter/getter of this property.
Immutable properties are so much nicer. Remove the setter and
ensure that the nm_plugin_missing property is only set during
object construction.
Unify the two check_ip_done() and check_ip_failed() functions into a
single one to have all the state transition logic in the same place.
This also fixes a regression introduced by commit 553717bb1c
("device: don't set ip4_state=IP_FAIL for ipv4.method=disabled").
After that commit the device immediately proceeded to IP_CHECK when
there was a disabled/ignore method. Now we wait for the termination of
the other method, like it used to be.

Some drivers (brcmfmac) don't change the MAC address right away.
NetworkManager works around that by waiting synchronously until
the address changes (commit 1a85103765).
wpa_supplicant on the other hand, only re-reads the MAC address
when changing state from DISABLED to ENABLED, which happens when
the interface comes up.
That is a bug in wpa_supplicant and the driver, but we can work-around by
waiting until the MAC address actually changed before setting the interface
IFF_UP. Also note, that there is still a race in wpa_supplicant which might
miss a change to DISABLED state altogether.
https://bugzilla.gnome.org/show_bug.cgi?id=770504https://bugzilla.redhat.com/show_bug.cgi?id=1374023
This was added by commit 4de8851eca, probably
by copying from NMDeviceVlan. It's not clear why a netlink request to
set the device IFF_UP would fail, or why that warrants a retry.
This retry loop was added by commit dc6341acec.
But I suspect, that the main-point there was not to retry the netlink
request to set the interface up. Why would that fail, and why would
a failure to set the interface up require a retry?
I think it was added to wait for carrier. But waiting for carrier was
later dropped with commit 5074898591
and it is not clear why we would wait for carrier at all -- we don't
do that for other device types either.
Instead of letting the sub-class check the "enabled" state, let
it be handled by nm_device_bring_up().
Note that nm_device_get_enabled() only has two implementations:
NMDeviceModem:bring_up() and NMDeviceWifi:bring_up().
The virtual function NMDevice:set_enabled() has two implementations:
NMDeviceModem and NMDeviceWifi. Likewise, the get_enabled() function
should also be implemented by those types.
The only caller of nm_device_get_enabled() is NMPolicy:schedule_activate_check().
It is correct to skip Wi-Fi devices based on their enabled state.
Long ago before commit 1b49f94, NetworkManager did not touch the
MAC address at all. Since 0.8.2 NetworkManager would modify the
MAC address, and eventually it would reset the permanent MAC address
of the device.
This prevents a user from externally setting the MAC address via tools
like macchanger and rely on NetworkManager not to reset it to the
permanent MAC address. This is considered a security regression in
bgo#708820.
This only changed with commit 9a354cd and 1.4.0. Since then it is possible
to configure "cloned-mac-address=preserve", which instead uses the "initial"
MAC address when the device activates.
That also changed that the "initial" MAC address is the address which was
externally configured on the device as last. In other words, the
"initial" MAC address is picked up from external changes, unless it
was NetworkManager itself who configured the address when activating a
connection.
However, in absence of an explicit configuration the default for
"cloned-mac-address" is still "permanent". Meaning, the user has to
explicitly configure that NetworkManager should not touch the MAC address.
It makes sense to change the upstream default to "preserve". Although this
is a change in behavior since 0.8.2, it seems a better default.
This change has the drastic effect that all the existing connections
out there with "cloned-mac-address=$(nil)" change behavior after upgrade.
I think most users won't notice, because their devices have the permanent
address set by default anyway. I would think that there are few users
who intentionally configured "cloned-mac-address=" to have NetworkManager
restore the permanent address.

... and don't set ip6_state=IP_FAIL for ipv6.method=ignore.
The disabled state is like having an empty NMIP4Config object.
It should not result in %IP_FAIL state. Instead, we just want
to proceed and commit an empty NMIP4Config instance.
This was introduced by commit 0652d9c596,
which I think was wrong.
Likewise, for ipv6.method=ignore we also don't want to mark the
IP state as failed. Instead, we want to proceed and set IP_DONE
right away -- without commiting anything, which is a difference
to the IPv4 case.
This is especially important, because an ip4_state/ip6_state of IP_FAIL
causes nm_device_can_assume_active_connection() to return FALSE, which
means we unmanage devices at shutdown. Ony might say that it doesn't
matter so much for a device without IP configuration, but imagine a
bond with VLANs on top that only has Layer 2 configuration. This will
bring down the entire stack.
With this change, devices with IP methods disabled/ignore stay up on
exit of NetworkManager (rh#1371126). Of course, that means on restart
software devices stay unamanged due to external-down (because since
commit e1edcda, devices without IP address are also external-down).
So, this really just fixes one scenario, breaking another one.
This should be fixed with bgo#746440 by not assuming connections.

brcmfmac and possibly other drivers don't change the MAC address
right away, but instead the result is delayed. That is problematic
because we cannot continue activation before the MAC address is
settled.
Add a hack to workaround the issue by waiting until the MAC address
changed.
The previous attempt to workaround this was less intrusive: we would
just refresh the link once and check the result. But that turns out
not to be sufficent for all cases. Now, wait and poll.

After the fix in [1], if the connection is assumed we don't update its
firewall zone. The goal of that change was to prevent NM from
interfering with the configuration done externally on devices not
created by NM.
However if there is an assumed persistent connection active on the
device NM touches the configuration in other ways, for example it
configures DHCP and manages the default route. So it seems correct to
also update the firewall zone.
OTOH, if the connection is assumed-generated there is no persistent
connection specifying a firewall zone and updating it makes no sense.
Bug [1] was about not interfering with devices unknown to NM (for
which there is no persistent connection) and so this change should not
conflict with the previous fix.
[1] https://bugzilla.redhat.com/show_bug.cgi?id=1098281https://bugzilla.redhat.com/show_bug.cgi?id=1366288
At this point we don't know if the slave has been using an assumed
connection that just vanished -- the best bet is to let the device be.
If it's meant to be unenslaved, it won't be due to an external event.

When a software device unrealizes, we want to forget about the "user-explict"
unmanaged state. It means, that after a software device is deleted, the
"user-explict" managed flag will be cleared for that device.
It might be nice to preserve the managed-state after deletion of the device.
However, the unrealized-device only exists as long as we have a connection
for the device. That means, before this patch whether the unmanaged flag
was forgotten depends on whether the user had some connections that keep
the device alive as unrealized. That behavior was complicated, just don't
do that.
It seems some drivers return success for nm_platform_link_set_address(),
but at that point the address did not yet actually change *sigh*.
It changes a bit later, possibly after setting the device up.
Add a workaround to retry reading the MAC address when platform indicates
success but the address still differs at first.
