Our lease is tracked in a plain string dictionary. For dhclient plugin
and similar, the keys are received via the environment, they are thus
unlimited. For the internal plugins they are known at compile time and
static strings. We thus sometimes need to clone the string, and
sometimes not.
Unfortunately, we cannot ask the GHashTable whether it has a free
function for the key, so we need to explicitly tell it. Add a parameter
for that.
dhclient exports the currently used IAID in the environment as
hex string. We expose this environment in our API, so this is also
the format that NetworkManager uses.
Accept setting the ipv[46].dhcp-iaid as hex string, so that the same
format is accepted on the profile.
While at it, also accept a hex number (0x) because it is also
convenient, and this change already introduces the precedent that the
IAID string is not unique/normalized.
There should be one function for parsing the string. Use it everywhere.
Also, because we will accept specifying the IAID as hex string so the
same parsing code should be used everywhere.
When a software device is deactivated, normally we schedule a idle
task to unrealize the device (delete_on_deactivate). However, if a new
activation is enqueued on the same device (and that implies that the
new profile is compatible with the device), then the idle task is not
scheduled and the device will normally transition to the different
states (disconnected, prepare, config, etc.).
For ovs-interfaces, we remove the db entry on disconnect and that
makes the link go away; however, we don't clear the hw_addr* fields of
the device struct.
When the new link appears, we try to set the new cloned MAC but the
stale hw_addr field indicates that it's already set. Avoid this
problem by updating the address as soon as the link appears.

The configure flag and APN for the initial EPS bearer are used when
bringing up cellular modem connections. These settings are only relevant
for LTE modems.

- Only consider preferred context of "internet" type. There can be
multiple preferred contexts of multiple types, and we care about
"internet" type only.
- Don't check for "internet+mms" type. It turns out that "internet+mms"
isn't a thing in oFono, and is used to represent "internet" context
with MMSC in the lomiri-system-setting's UI only.

Ensuring to have 1000 bytes available is not a good start.
Because, if we start with an empty buffer (allocated fewer
than 1000 bytes), on first call we will reserve 1000 bytes.
If we then just read one byte, on the next read we would again
try to reserve 1000 bytes, and already require a reallocation.
In this case it is better to reserve 488+1 or 1000+1 bytes.
"configure-for-system.sh" is supposed to be in sync with
NetworkManager.spec. Update for the recent changes.
Also add a make/ninja call at the end. Almost always we want to build
after the configure.
When building network-manager in cross-compile environment meson is not able
to detect the right location of the mobile-broadband-provider-info
database by using the pkg-config module.
By adding the option 'mobile_broadband_provider_info_database' to set the
correct path to the datafile this can be solved.

- only printing the scan list is not gonna cut it. It's usually stale,
and we need to request a new scan.
- don't hard-code the GEnum and GFlags values that we understand. We
have libnm, which provides us some meta information about the data.
Use it.
- Some code cleanup.

We also do that with g_return*() macros. These strings increase the
binary size for little use. Drop them, unless we build with
more asserts enabled.
This affects nm_assert() messages.
glibc defines __assert_fail as:
extern void __assert_fail (const char *__assertion, const char *__file,
unsigned int __line, const char *__function)
__THROW __attribute__ ((__noreturn__));
but musl as:
_Noreturn void __assert_fail (const char *, const char *, int, const char *);
(note the difference in the type for the line argument).
This cannot be made to work, unless we would detect the used type at configure
time, which seems too much effort.
Drop this again.
This reverts commit 1ce29e120b.

[thaller@redhat.com: I introduced this bug when taking the original patch].
Fixes: 820f6f3a4a ('contrib/rpm: sync obsoletes_{initscripts_updown,ifcfg_rh} version')
Initially, when we obsoleted {initscripts_updown,ifcfg_rh}, the package
versions that we build from this upstream spec file differed from what
we put into Fedora/RHEL.
By now, this is long gone, and for upstream package builds we don't care
to accurately track the version, when using upstream/copr builds. Just
sync the version to what they are in Fedora/RHEL.
The idea of nm_free_secret() is to clear the secrets from memory. That
surely is some layer of extra snake oil, because we tend to pass secrets
via D-Bus, where the memory gets passed down to (D-Bus) libraries which
have no idea to keep it private. Still...
But turns out, malloc_usable_size() might not actually be usable for
this. Read the discussion at [1].
Stop using malloc_usable_size(), which seems unfortunate.
There is probably no secret relevant data after the NUL byte anyway,
because we tend to create such strings once, and don't rewrite/truncate
them afterwards (which would leave secrets behind as garbage).
Note that systemd's erase_and_free() still uses malloc_usable_size()
([2]) but the macro foo to get that right is terrifying ([3]).

(cherry picked from commit 8b66865a88)
NetworkManager dispatcher will now run dispatcher scripts with 'reapply'
as action as well. Each time the connection is reapplied on a device,
this action is triggered. Document this action in the documentation.
(cherry picked from commit 0e3d2c367c)
Trigger a dispatcher event when a connection is reapplied on a NM device.
Some devices such as phones have already a DHCP client running for accepting
connections when they are plugged into USB to transfer data over SSH.
When NetworkManager switches the connection IP method to shared,
it spawns a dnsmasq process to handle DHCP and DNS for that connection.
However, a dispatcher event is needed to disable the external DHCP server
for these USB connections as NetworkManager's dnsmasq handles them now.
Moreover, when the connection method is switched to a different mode,
the external DHCP server needs to be spawned again to make sure that
SSH connections are still possible to the device.
To achieve this, add a new NetworkManager Dispatcher event
'reapply' which is triggered when a connection is reapplied on a NM
device. This way, a dispatcher script can handle the case above by
inspecting the IP method in the dispatcher script.
