For now, just detecting the device and creating generic MBIM or AT
based modems.

meson generates the `mm-daemon-enums-types` source and header files.
These are used when building `ModemManager` executable and different
plugins. However, these enums are only stated as dependencies on the
`ModemManager` executable build.
This has been fixed by also adding the generated files targets as
dependencies in the required plugins.
|
|
The `broadmobi`, `dlink`, `telit` and `tplink` plugins include the
`mm-port-enums-types.h` header. However, they do not use any symbol
defined there.
The `huawei` plugin as includes the `mm-port-enums-types.h` header
but it does not include the build targets as dependencies.
These issues have been fixed by removing the unnecessary includes
from `broadmobi`, `dlink`, `telit` and `tplink` plugins and by
including the enums build target in the `huawei` target.

This silents a warning given by udev:
Configuration file /usr/lib/udev/rules.d/77-mm-fibocom-port-types.rules is marked executable. Please remove executable permission bits. Proceeding anyway.

We won't create a full new different modem object based on whether the
ID_MM_FIBOCOM_INITIAL_EPS_OFF_ON tag is found or not. Instead, we
always will create the same object type, and detect whether the OFF/ON
cycle is required during runtime.
|
|
Assume that the method to change the initial EPS bearer settings is
always implemented in the parent, so that we can avoid the runtime
check.
This also fixes the codepath that would happen if the
iface_modem_3gpp_parent->set_initial_eps_bearer_settings == NULL
condition was valid, as that would end up with a GTask never completed.
|
|
When the attach APN settings are changed, the device will go through a
radio on -> radio off -> radio on cycle so that the new changes are
taken into consideration.
This change is done in a Fibocom-specific MBIM modem implementation
because it's working around a firmware bug that would prevent for the
attach settings to be considered automatically.

fwupd expects device IDs which are unique for each device and its
variants. However, Quectel re-uses the same USB VID & PID among
different variants such as EG25, EC25, EC20, etc. Moreover, each
variant may have subvariants such as EG25GGB, EG25GGC, EG25AFF,
EG25AFX, etc.
Add the name of the modem to the device IDs to build more unique device
IDs such as USB\VID_2C7C&PID_0125&REV_0001&NAME_EC25GGB.

To identify which devices support the firehose update protocol.

The 'update_settings' object must be referenced before the task is completed.

Fibocom's documentation states that we must double-check the connection
is established when setting up an ECM connection. The possible replies -
according to the documentation - are:
+GTRNDIS: <state>,<cid>,<ip>,<prim. dns>,<sec. dns>
OK
or
+GTRNDIS: 0
We just care about the state value which is 1 if everything worked.
|
|
Some modems might have a net port but don't support +GTRNDIS which is
used by the ECM bearer. That case will be caught by this additional
check.
|
|
|
|
|
|
|
|
This is required in order to be able to use a custom bearer which in
turn is necessary for establishing ECM connections.

Quectel modems report only their major firmware version through
AT+GMR, use AT+QGMR instead to report the full firmware version.
|
|
Quectel EG25-G QMI modem firmware revisions are not matched with carrier configs.
Different VoLTE profiles might be selected by the user causing
the carrier config revision to change.
Since fwupd uses this string for firmware updates, it gets confused and
thinks the user has an update available.
|
|
The modem may report the 'apn-type' field is the one to be used as
index; if that's the case, allow setting and deleting profiles based
on the given 'apn-type' field.
This change also makes the internal profile management operations use
one index field or another, based on what the protocol implements.

Main thing that's required to get modem hot-swapping to work is the
UDCONF=50,1 command(see u-blox AT-command manual). But there are a lot
of u-blox modules which do not support this command. So in this patch,
it's supposed that this thing is configured beforehand(Like the UUSBCONF
functioning mode) for modules, where SIM hot-swaping feature is
possible. For the modems where it's not, the patch will not have any effects.
----
For ublox modems, CIEV: 12(X) messages allow to know if
SIM is (un)plugged. The values are encoded as:
- 0: no SIM detected
- 1: SIM detected
It's required from a modem to generate these events about the SIM
detection state.
To set up these `CIEV: 12,(X)` URC events the `+CMER=1,0,0,1,0` command
is used. That command is supported by almost all u-blox modems except
SARA-G300/SARA-G310/LEON-G1(For these models the hot-swap feature will
not work).
As this 12 that is used in CIEV may be completely different in other
modules, the test command parsing is quite important to get that index
number. So, this logic is also added in cind_simind_format_check_ready
function.
----
It seems that it's necessary to issue this `+CMER` set up there despite
that the `+CMER` configuration will take place later in the 3GPP
interface enabling sequence. Because without it simind indications
will not be enabled at all.
CMER configuration may be later overwritten by 3GPP interface enabling
sequence, but in the worst-case scenario only hot-swap feature will not
work.

If we have a modem with an established connection, and then the
SIM is getting removed from that modem, this forces modem reprobing
sequence.
It looks like that:
```
mm-base-modem:mm_base_modem_process_sim_event
-> mm-base-modem:mm_base_modem_disable
-> mm-base-modem:disable
-> mm-broadband-modem:common_disable
-> mm-broadband-modem:disabling_step,
-> ctx->step=DISABLING_STEP_FIRST
-> ctx->step=DISABLING_STEP_WAIT_FOR_FINAL_STATE
-> ctx->step=DISABLING_STEP_DISCONNECT_BEARERS
```
At this stage, there is no actual connection existing already, but
bearer objects still exist and are still marked as connected.
So, if there were any active bearers - they will be disconnected.
In order to disconnect, ublox bearer sends +CGACT=0,%u, modem then
will return CME ERROR: 10(SIM not inserted):
```
[modem0/ttyACM0/at] --> 'AT+CGACT=0,1<CR>'
[modem0/ttyACM0/at] <-- '<CR><LF>+CME ERROR: 10<CR><LF>'
[modem0/ttyACM0/at] operation failure: 10 (SIM not inserted)
[modem0/bearer0] couldn't disconnect: SIM not inserted
```
this error will break disabling and reprobing. To fix that, it's
require to add 'SIM not inserted' state as a valid condition to
continue bearer disconnection.

The port type hints for the FM101 were updated to be in line with the final product layout,
where USB interface #2 is now used as an AT port (not ignored) and USB interface #4 is now
used as debug port. USB interface #6 is removed as it no longer exists.

The udev rules expect matches based on shell globbing pattern, not
based on regex. This means that "[0-9]*" doesn't mean "zero or more
digits", it actually means "one digit and zero or more other
characters".
So, avoid the regex like match, even if it worked for us, because it
didn't mean what we thought it meant, plus, it breaks our custom udev
rules processing logic, in which we convert the input patterns into
real regex expressions.
See https://bbs.archlinux.org/viewtopic.php?pid=1415916#p1415916
While at it, also make sure that the wildcard matching is done
exclusively for prefix and suffix matches, never in the middle of
a string, or our custom rules parser would not match correctly.

We remove the built-in FCC unlock procedures from the ModemManager, we
will no longer run them automatically, and instead rely on external
scripts/programs to do that.
Packages providing the external FCC unlock tools can install them in
${pkglibdir}/fcc-unlock.d.
Users manually enabling external FCC unlock tools can install them in
${pkgsysconfdir}/fcc-unlock.d.
The user-enabled path takes precedence over the package-enabled one.

This patch add fibocom FM101 to 77-mm-fibocom-port-types.rules file.
which contains two sets of vid and pid pairs, "2cb7:01a2" and "2cb7:01a4".

Different options are set as `feature`, also every possible plugin,
but this may cause confusion.
All options set as `feature` but plugins have been made `boolean` to
avoid further confusions.
`help2man` is also installed in the CI image because is required to
build different libraries.

We keep the 'WHITELIST-ONLY' filter type name still as an option in
--filter-policy=[POLICY], but deprecated and with the better
'ALLOWLIST-ONLY' replacement suggested from now on.

For T99W175, Qualcomm realized mcfg switching mechanism
in FW side. It can work indepently without MM's help.
Therefore, delete mcfg switching mechanism in MM.

When trying to lock the modem LE910S1 replies:
'AT+CSIM=1<CR>'
'<CR><LF>ERROR<CR><LF>'
but the modem actually supports CSIM unlock retries reporting.

Telit modems that require hexadecimal number when specifying 4G bands
also reply to #BND=? command with a 4th parameter <LTE_band_ext>
(e.g. LM940, LM960, LN920, FN980).
On the other hand, modems that require decimal number when specifying 4G
bands only return 3 parameters to the same command.
It is then possible replace the detection of ext_4g_bands via UDEV tags
with an inspection of BND=? reply.

Since the 'wwan' subsystem addition to the qcom-soc plugin, the rules
to say a modem is handled by this plugin are too broad, and the plugin
attempts to support any kind of device exposed by the WWAN subsystem,
not just those from Qualcomm SoCs.
Update the plugin to require a new ID_MM_QCOM_SOC udev tag that is set
in the plugin udev rules, given that these rules already check for the
expected SoC drivers (bam-dmux, ipa, qcom-q6v5-mss).

Improved the way the plugins are set to allow a smaller summary.
