Rework update_system_hostname() to use the new properties from the
hostname setting.
In the default configuration where all the 3 boolean properties
hostname.{from-dhcp,from-dns,only-from-default} are true, the behavior
is the same as before.
The following merge request in ModemManager introduces a more or less
common timeout value for the connection attempts in all plugin and
protocol implementations:
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/391
The value chosen by default for the steps that may take long to
complete in a connection attempt is 180s, and 120s for the steps in
the disconnection path.
Until now, every different plugin or protocol had a different timeout
value, all of them <= 180s, and with that change in ModemManager, the
values are now aligned for all.
Note, though, that this does not mean that a connection attempt will
take always less than 180s, as there may be multiple other steps in
addition to the one that took the maximum timeout. The value chosen
for NetworkManager is a compromise between the new defaults from MM
and what the user would expect under e.g. very low quality conditions.

In connection_removed we use the id.name that was being g_freed a few
lines further down.

C casts unconditionally force the type, and as such they don't
necessarily improve type safety, but rather overcome restrictions
from the compiler when necessary.
Casting a void pointer is unnecessary (in C), it does not make the
code more readable nor more safe. In particular for g_object_new(),
which is known to return a void pointer of the right type.
Drop such casts.

Before, ovsdb_call_method() has a long list of arguments
to account for all possible commands. That does not scale.
Instead, introduce a separate OvsdbMethodPayload type and
only add a macro to allow passing the right parameters.
The text should match the OvsdbCommand enum. If the enum
value is named OVSDB_ADD_INTERFACE, then we should print
"add-interface". Or alternatively, if you think spelling
out interface is too long, then the enum should be renamed.
I don't care, but name should correspond.
ovsdb sends monitor updates, with "new" and "old" values that indicate
whether this is an addition, and update, or a removal.
Since we also cache the entries, we might not agree with what ovsdb
says. E.g. if ovsdb says this is an update, but we didn't have the
interface in our cache, we should rather pretend that the interface
was added. Even if this possibly indicates some inconsistency between
what OVS says and what we have cached, we should make the best of it.
Rework the code. On update, we compare the result with our cache
and care less about the "new" / "old" values.
We will call the function directly as well. Lets aim to
get the types right.
Also the compiler would warn if the cast to (GDestroyNotify)
would be to a fundamtally different function signature.
GHashTable is optimized for data that has no separate value
pointer. We can use the OpenvswitchBridge structs as key themselves,
by having the id as first field of the structure and only use
g_hash_table_add().
Of course, in practice "mtu" is much smaller than 2^31, and
also is sizeof(int) >= sizeof(uint32_t) (on our systems). Hence,
this was correct. Still, it feels ugly to pass a unsigned integer
where not the entire range is covered.
- rename "id" to something more distinct: "call_id".
- consistently use guint64 type. We don't want nor need
to handle negative values. For CALL_ID_UNSPEC we can use
G_MAXUINT64.
- don't use "i" format string for the call id. That expects
an "int", so it's not clear how this was working correctly
previously. Also, "int" has a smaller range than our 64bits.
Use instead "json_int_t" and cast properly in the variadic
arguments of json_pack().
Also, never update the value to %NULL. If the current
message does not contain a UUID, keep the previous one.

"nm-device-logging.h" defines logging macros for a NMDevice instance.
It also expects a "self" variable in the call environment, and that
variable had to be in the type of NMDevice or the NMDevice subclass.
Extend the macro foo, so that @self can be either a NMDevice* pointer
or a NMDevice$SUBTYPE.
Of course, that would have always been possible, if we would simply cast
to "(NMDevice *)" where we need it. The trick is that the macro only
works if @self is one of the two expected types, and not some arbitrary
unrelated type.
Kernel does a auto-mtu adjusting process whenever a port is added/removed from
the bridge, this can cause issues when NM wants to explicitly set an MTU which is
equal to the bridge default one (1500) because if later a port is added with a
different MTU the kernel will assign the bridge that port's MTU resulting in the bridge
runtime configuration differing from the bridge's NM connection profile.
What we can do is to always apply the MTU manually for the bridge (if explicitly
set by the profile), after doing so the kernel won't modify the MTU anymore,
which is what we want, problem is that kernel won't actually apply the MTU
to the netdev if it's not actually changing so we first apply it to
MTU-1 and then to the desired value.

- we commonly use "int addr_family" as parameters to functions.
But then inside the function, we often need to do something for
IPv4 or IPv6 specifically. Instead of having lots of redundant
"if (addr_family == AF_INET)" checks, prefer to have a variable
IS_IPv4 and/or use NM_IS_IPv4() macro.
- don't make the "IS_IPv4" variable a gboolean but an int. gboolean
is a typedef for int, so it's in practice exactly the same. However,
we use "IS_IPv4" as index to arrays of length 2, where at position
"1" we have the value related to IPv4. Using a gboolean to index
an array is a bit odd. Maybe a "int" is preferable here.
This is more about doing consistently one or the other. There are
no strong reasons to prefer gboolean or int.
Apparently it is not actually used, but the function implements
a return value for AF_UNSPEC, while also asserting that the addr_family
is AF_INET/AF_INET6. Drop the assertions.
These macros are consistent with NMP_OBJECT_TYPE_IP_ADDRESS()
and NMP_OBJECT_TYPE_IP_ROUTE(), in name and usage.
Replace the previous functions that had inconsistent and a verbose
naming.
It's a bit ugly that NMActRequest also tracks the shared rules.
Why? It's just some additional state (the rules) and some additional
actions that should be done when activating/deactivating the profile.
NMActRequest also doesn't track the NMDhcpClient, so why these shared
rules?
Also, removing the rules from an object destructor is ugly. NMActRequest
is a GObject and ref-counted. We should not make assumptions when the
last reference gets releases, at least not in cases like this, where
we hand out the reference and the object is passed around through large
parts of the source code.
For now, still let NMActRequest keep track of NMUtilsShareRules.
Later this will be refactored too.
A static const array is marked as immutable by the linker.
This is what we want, because there is no need to change this
array.
Also, the tailing %NULL entry is not necessary, we can just
iterate over the fixed number of elements.
For hidden networks, we usually don't have an SSID. We try to match
and fill the SSID based on the profiles that we have:
<debug> [1603798852.9918] device[6b383dca267b6878] (wlp2s0): matched hidden AP AA:BB:CC:DD:EE:FF => "SSID"
However, we should not clear that value again on the next update:
<trace> [1603798856.5724] sup-iface[66c1a0883a262394,0,wlp2s0]: BSS /fi/w1/wpa_supplicant1/Interfaces/0/BSSs/3 updated
<debug> [1603798856.5726] device[6b383dca267b6878] (wlp2s0): wifi-ap: updated AA:BB:CC:DD:EE:FF (none)
Once we have a SSID, we can only update it to a better value,
but not clear it.
