This bug was not causing a crash for me because of the !IS_NM_DEVICE_IWD
check and because my glib version probably had the assertion within
NM_IWD_MANAGER_GET_PRIVATE disabled.
While there, change the g_signal_connect line to use the macro for the
signal name.
Make sure .set_enabled uses the Device.Powered property to basically
bring the netdev UP and DOWN as I understand is expected by the
nm_device logic.
Device.Powered should generally reflect the UP state immediately but
just to avoid possible race conditions .is_available() will now return
a value that is an AND of the local "enabled" state and IWD's Powered
property.
Change from the default dbus call timeout (-1) to infinite (G_MAXINT)
because the call may now include the secret requests which have their
own timeout policies.
Remove the code (mostly copied from nm-device-wifi.c) that handles
checking if the secrets were provided and requesting missing secrets
before starting a connection attempt. Instead, request secrets when
we're asked for them by IWD through its agent interface. This happens
while the dbus Connect call is running. We change the NMDevice from
the CONFIG state to NEED_AUTH and then change back to CONFIG once we
sent the secrets back to IWD.
The current code would require the secrets only based on whether a
network is a KnownNetwork but IWD may need a new passwords even for
KnownNetworks if the last connection attempt has failed.
The parsing of the certificate consists of a series of checks, and if a
check matches, we determine the type and are done.
Moving these checks to different functions (that are only called once)
makes it more complicated to understand what really happens. Merge them
all together.
Refactor cert_parser() to return early.
Also, rework handle_as_scheme() and handle_as_path() to check for
success first and return early. This in the next step will allow
to merge the functions.
Always read and load ipv4 property values when method is shared also if
they will not be used: instead of dropping them at connection update,
keep their values in the ifcfg file.
Exceptions: ipv4.dns and ipv4.dns-search. They will be not read, otherwise
they may trigger a failure in nm-setting-ip4-config.c:verify() on load.

Passing ownership with a function call is confusing. Don't do that.
Since we have the cleanup attribute, it doesn't significantly
complicate the callers, as all they need to do is marking the
@msg variable to free the message when going out of scope.
That results in the function that allocates the message also being
responsible to free it.
The callers expect _nl80211_send_and_recv() to free @msg.
This was broken by the previous commit, which wrongly removed
the nm_auto_nlmsg cleanup attribute.
Fix the compiler warning differently.

It's very likely that the product said something that was filtered out
by the fixup, such as "PCI Ethernet" or "Wi-Fi Adapter". Use a generic
type name in place of it.
The product names are generally of rather poor quality. The product name
is no place to enumerate product capabilities, the bus it's attached on
and similar nonsense.
If there's a [<string>] that survived the substitution, then the string
is supposed to be a short form that is generally preferrable.
That's great in theory, but actually it's rather often pure garbage for
product names. Let's prefer it just for vendors and provide an option to
drop it (will be useful for fixing up product names).
The hwdb generally contains the strings of rather poor quality,
especially when it comes to sensibly presenting them to the user and
they need various cleanups.
While the following patches add fixups, this one splits out vendor
fixups, because it turns out that a different set of fixups is needed
than for products.
systemd commit f11cba7479fe ("libsystemd-network: fix unaligned loads
(issue #7654)") changed the way in which the MAC address is read to
use native endiannes:
htobe32(*((uint32_t *)x) -> unaligned_read_ne32(x)
This is wrong because loads done with BPF_LD + BPF_ABS are big-endian, as it
can be seen for the ethertype and arp-operation loads above in the
filter. Also, the same commit changed:
htobe32(*((unsigned int *)x) -> unaligned_read_be32(x)
in _bind_raw_socket(), which is the correct form.
The commit broke IPv4LL in presence of loops, as the sender now considers its
own packets as conflicting.

Now that every call to nm_device_set_ip_iface() and nm_device_set_ip_ifindex()
is checked, and setting an interface that does not exist causes the device
state to fail, we no longer need to allow setting an ip-iface if we are
unable to retrieve the ip-ifindex.
Depending on the bearer's configuration method, the data-port is
either a networking interface, or an tty for ppp.
Let's treat them strictily separate.
Also, rework how NM_MODEM_DATA_PORT was used in both contexts.
Instead, use the that we actually care about.
Also, when nm_device_set_ip_ifindex() fails, fail activation
right away.
Also, we early try to resolve the network interface's name to
an ifindex. If that fails, the device is already gone and we
fail early.
nm_device_modem_new() is only called with a newly created
NMModemBroadband or NMModemOfono instance.
See the callers
- NMModemManager:handle_new_modem()
- NMWwanFactory:modem_added_cb()
- NMDeviceModem:nm_device_modem_new()
Hence, at that point, the modem cannot yet have a data-port
or ip-iface set, because that is only obtained later.
- don't even bother to look into the platform cache, but use
if_indextoname() / if_nametoindex(). In most cases, we obtained
the ifindex/ifname not from the platform cache in the first
place. Hence, there is a race, where the interface might not
exist.
However, try to process events of the platform cache, hoping
that the cache contains an interface for the given ifindex/ifname.
- let set_ip_ifindex() and set_ip_iface() both return a boolean
value to indicate whether a ip-interface is set or not. That is,
whether we have a positive ip_ifindex. That seems more interesting
information, then to return whether anything changed.
- as before, set_ip_ifindex() can only clear an ifindex/ifname,
or error out without doing anything. That is different from
set_ip_iface(), which will also set an ifname if no ifindex
can be resolved. That is curreently ugly, because then ip-ifindex
and ip-iface don't agree. That shall be improved in the future
by:
- trying to set an interface that cannot be resolved shall
lead to a disconnect in any case.
- we shall make less use of the ip-iface and rely more on the
ifindex.
The error should be freed by callback functions, but only
_monitor_bridges_cb() actually does it. Simplify this by letting the
caller own the error.
