2023-03-27port-probe: don't assume port is QCDM when QCDM is not requiredAleksander Morgado
When QCDM is not required we don't run an explicit QCDM port probing operation. In this case, though, we should not assume that the port is QCDM capable, even if it is also flagged as ignored. Instead, we'll flag the port as QCDM capable and ignored only if there was a udev port type hint associated to the port. Otherwise, we'll report the port as not being QCDM capable, and the port won't even be reported in the list of ports as its type is unknown.

Just ignoring the received indications is not enough, because they could arrive after the operation response has been processed. We now explicitly disable the indications by reconfiguring the modem before and after every profile update operation triggered by our own logic.

2023-02-21base-manager: fix crash when uninhibiting partially removed deviceAleksander Morgado
If the device is not fully removed from the system during inhibition and port additions happen, we reach a state where the MMDevice object is still tracked by ModemManager and we also have new port additions tracked that will require explicit port probings before a new modem object can be created. Solve this mixup by faking the removal of all existing device ports, which will end up completely removing hte MMDevice, so that new port additions reported afterwards also involve the full device probing process triggered by the plugin manager. The issue could be reproduced easily on a MBIM device that also exposed TTYs, as follows: * mmcli -m a --inhibit, leave it running * rmmod cdc_mbim && sleep 5 && modprobe cdc_mbim (so that the cdc-wdm and net ports go away from the system but NOT the TTYs.) * Cltr+C to stop the inhibit in the mmcli call. ModemManager would assert as follows: 0x000079918bcf2a3f (libc.so.6 + 0x00087a3f) pthread_key_delete 0x000079918bca7c6c (libc.so.6 + 0x0003cc6c) gsignal 0x000079918bc93462 (libc.so.6 + 0x00028462) abort 0x000079918bf26f03 (libglib-2.0.so.0 - gtestutils.c: 3253) g_assertion_message 0x000079918bf26f66 (libglib-2.0.so.0 - gtestutils.c: 3279) g_assertion_message_expr 0x0000594ff1093d0c (ModemManager - mm-base-manager.c: 1110) remove_device_inhibition 0x0000594ff1093968 (ModemManager - mm-base-manager.c: 1247) inhibit_device_auth_ready 0x000079918c0536a8 (libgio-2.0.so.0 - gtask.c: 1230) g_task_return_now 0x000079918c0536db (libgio-2.0.so.0 - gtask.c: 1244) complete_in_idle_cb 0x000079918bf053fc (libglib-2.0.so.0 - gmain.c: 3417) g_main_context_dispatch 0x000079918bf05704 (libglib-2.0.so.0 - gmain.c: 4211) g_main_context_iterate 0x000079918bf05978 (libglib-2.0.so.0 - gmain.c: 4411) g_main_loop_run 0x0000594ff108de66 (ModemManager - main.c: 217) main 0x000079918bc936c5 (libc.so.6 + 0x000286c5) __libc_init_first 0x000079918bc93781 (libc.so.6 + 0x00028781) __libc_start_main 0x0000594ff108db80 (ModemManager + 0x00061b80) _start
2023-02-20broadband-modem-mbim: limit the use of context types defined in MBIMExAleksander Morgado
The Tethering context type UUID was defined by Microsoft in its extensions as `5e4e0601-48dc-4e2b-acb8-08b4016bbaac` (along with others like Admin, Xcap, App and EmergencyCalling), see https://learn.microsoft.com/en-us/windows-hardware/drivers/network/mb-provisioned-context-operations. These UUIDs are expected to be usable only if the modem supports `MBIM_CID_MS_PROVISIONED_CONTEXT_V2` (CID=1) in the Basic Connect Extensions service (3d01dcc5-fef5-4d05-0d3abef7058e9aaf). If the modem doesn't support these, we should try to fallback to a more generic APN type automatically, e.g. "Internet", which was defined in MBIM 1.0 and should always be supported. There should be no problem in a modem to have 2 separate PDN connections with the same context type.
