We try to combine in common envvars the compiler and linker flags shared by the
different components, and where possible, also re-using the implicit AM_CFLAGS
and AM_LDFLAGS variables that automake provides, and which apply to all objects
being built in the same Makefile.am.
The internal libmodem-helpers.la library is also renamed to libhelpers.la
* Add new async virtual method init_current_storages to
MMIfaceModemMessaging
* Add logic of init_current_storages to MMBroadbandModem
* Add step "INIT_CURRENT_STORAGES" in MMIfaceModemMessaging
initialization in order to load and store current SMS
storages for mem1 and mem2.
* Add usage of current sms storage value for mem1 in place
of an empty string parameter when the command AT+CPMS
is used.

The CPMS test parser was expecting 3 groups (parenthesis enclosed lists) of
memory IDs, e.g.:
+CPMS: ("SM","ME"),("SM","ME"),("SM","ME")
But some modems like the Huawei MU609 may just report single elements, not
groups, e.g.:
+CPMS: "SM","SM","SM"
This patch avoids using g_strsplit() to split the groups, as that is unaware
of the possible replies without groups. Instead, a new helper method is
implemented which does the group/item split itself, considering also the
possibility of a reply with mixed groups and non-groups, like e.g.:
+CPMS: ("SM","ME"),"SM","SM"
Additionally, we also now support the case where the groups are empty, e.g.:
+CPMS: (),(),()
https://bugs.freedesktop.org/show_bug.cgi?id=92243
Variability in the response style from certain modems causes the parsing
of the +CGMR response to fail. For example, the Telit HE910 inserts an
empty string ("") in the second field of the response, causing the
sscanf implementation to fail.
This patch converts the parsing of the CGMR response to a regex that
allows for more flexibility and robustness, and adds unit tests around
the parsing call.

Build all targets, except for CLI tools (mmcli, uml290), with special
flags needed for collecting code coverage information when the build has
been configured with --enable-code-coverage.
Three new targets are available in the top build directory:
- `check-code-coverage' runs the test suite and generates a code
coverage report,
- `code-coverage-capture' generates a code coverage report from already
collected data, which can come in handy when one wants to see code
paths touched by a particular test,
- `code-coverage-clean' removes the collected coverage data and the
generated reports.
The QCDM port commands are never cached, so remove the option from the command()
method. Will also simplify command caching afterwards as it will be an AT-only
thing.
This patch modifies mm_3gpp_parse_iccid() to auto-detect if an ICCID
response is character swapped or not by comparsing the major industry
identifier part of the ICCID response to the known value (89) for
telecommunication purposes. This addresses the issue where the same AT
command (e.g. AT^ICCID used by the huawei plugin) does not report ICCID
in a consistent format.
The format of CREG/CGREG/CEREG responses is not very precisely defined
in or strictly enforced by the 3GPP specifications. That leads to the
fact that some modems put leading zeros in integer type fields (e.g.
<n>, <stat>, <AcT>), and not all modems put double quotes around string
type fields (e.g. <lac>, <ci>) in those C*REG responses.
For example, 0001 can be a valid value for both <stat> and <lac>. The
original C*REG parsing code in ModemManager could potentially interpret
'+CREG: <stat>,<lac>,<ci>,<AcT>' as '+CREG: <n>,<stat>,<lac>,<ci>'. This
patch addresses this issue by refining the regular expressions returned
by mm_3gpp_creg_regex_get() with the following assumptions:
1. If a modem puts leading zeros in integer type fields, it puts double
quotes around string type fields.
2. If a modem omits double quotes around string type fields, it does not
put leading zeros in integer type fields.
Tests had either their own g_print()s or they would enable a _mm_log() method to
get all g_debug()s from the libraries printed. In order to cleanup the result of
the tests run, avoid this stdout dumps by default, and only enable them if
explicitly enabled in CFLAGS, e.g.:
$> ./configure CFLAGS="-DENABLE_TEST_MESSAGE_TRACES"
Changes being:
* Don't rely on the band preference TLVs presence. The band preference TLVs are
always given, even if the modem doesn't support the specific capability right
away. E.g. a GSM/UMTS/LTE modem configured with 'gsm-umts' capability (no
'lte') still shows the LTE band preference TLV in the SSP responses.
* Don't automatically add LTE as current capability. We needed this when we
were not able to change capabilities, so that we didn't lose the ability to
set 4G mode as allowed.
And also make it a list of masks, specifying which are the specific combinations
supported, not just one mask with all.
E.g.:
-------------------------
Hardware | manufacturer: 'Sierra Wireless, Incorporated'
| model: 'MC7710'
| revision: 'SWI9200X_03.05.19.04ap r5475 carmd-en-10527 2012/09/17 17:57:14'
| supported: 'gsm-umts
| gsm-umts, lte'
| current: 'gsm-umts, lte'
| equipment id: '358178040668164'
For loading current capabilities we use a mix of "Technology Preference" (TP),
"System Selection Preference" (SSP) and DMS-reported capabilities. But, as we
also use TP and SSP for allowed modes, it may be the case that we end up
leaving 4G out of the allowed modes, which afterwards will make the modem not
report LTE as current capabilitiy, as TP/SSP don't include LTE.
So, just assume LTE is a current capability if DMS-reported capabilities include
it. We can really do this because LTE is the only 4G technology, the same logic
wouldn't apply correctly for 2G or 3G (due to having different techs for 3GPP
and 3GPP2).
We don't want to support only 'relative' validity, so don't assume that the
Validity property will always be a uint32 value.
Instead, we define the Validity propery as '(uv)' tuple, where the first value
(a MMSmsValidityType) specifies the type of validity, and the second value is
a variant formatted accordingly to what the validity type specifies (e.g. a
uint32 value if the type is MM_SMS_VALIDITY_TYPE_RELATIVE).
Pantech UMW190 modem uses a custom +CMGL response which includes only
three fields before the actual PDU, e.g:
+CMGL: <index>,<status>,<something>\r\n<PDU>
instead of what we had before:
+CMGL: <index>,<status>,<alpha>,<length>\r\n<PDU>
The CMGL parsing logic is now updated to use a regex to match the reply, and
also considering the UMW190 specific case.
Actually, we end up reading only the two first fields (index and status) which
are the ones we really need, so we skip the <length> and the <alpha> if given.
Added also unit tests to cover all these known cases.
Partially fixes https://bugzilla.gnome.org/show_bug.cgi?id=696723 (missing the
actual PDU parsing fixes).
+GSN response differs widely between modems. Some prefix the
MEID and/or ESN with 0x, some have leading zeros, some return the
MEID and the ESN, and some append the serial number to the end of
the IMEI. Handle that and make the ESN, MEID, IMEI, and
EquipmentIdentifier parsing consistent.
This patch adds the support for solicited/unsolicited EPS network
registration status via AT+CEREG, which is configurable via the
'iface-modem-3gpp-eps-network-supported' property of the
MMIfaceModem3gpp interface and is disabled by default.
