Only for basic SMS-SUBMIT PDUs at the moment, and doesn't
support large SMSs yet.

There's no encoding information about 8-bit SMS messages,
and they are often binary things like ringtones or voicemail
indicator commands. Since there's no point to our parsing
them just let clients deal with it.

Various bits of the code didn't check if response was valid
or not during error conditions, and when an error occurs
sometimes it'll be NULL (since not all errors are translated
errors from the modem, some are serial or general ones). We
have to make sure we don't try to use response->str when
response doesn't exist.
Found in the generic CDMA code likely as a result of
d5d9eec2b52363a7460aeec0c020b1c6a7af6b03 but was a bug long
before that commit happened anyway.

Change the error handling to be a bit more like what appears to have
been intended: if constructing the regex fails, report an error and
return. The existing code looked like it was set up to do this, but
wasn't quite wired together, and had process-terminating calls
(g_error()) followed by other code.

First, arrange for received/complete signals to be sent by calling
cmti_received_has_sms() with the message properties even if the
message isn't complete yet.
Second, make the operation of the List command's multipart message
handling independent of message order by doing one pass to insert the
messages into the cache and second pass to retrieve the complete messages.

Reporting errors instead of just returning permits routines like
mm-generic-gsm.c:simple_get_status() to work again, as their callbacks
get the error they are expecting. To make this work, adapt get_csq_done()
to handle a NULL response when error is set, and make sure that multiple
errors don't step on each other in the mm_callback_info_chain() sequence
created by simple_get_status().

Some modems don't allow most commands when they are PIN locked, so
the initial facility lock check errors out. Check the locks again
after the SIM is unlocked.
|
|
The property EnabledFacilityLocks on the .Modem.Gsm.Card interface
is a bit mask that indicates which of the various personalization
codes from 3GPP TS 22.022, plus the SIM PIN lock and SIM PIN2 lock,
are enabled. The set of facility locks supported by the modem is
determined at the time the modem is initialized, and the state of
each supported lock (enabled or disabled) is determined. When the
state of a lock changes, a property-change signal is sent out. Note
that ModemManager only supports enabling and disabling SIM-PIN, via
the EnablePin method on Modem.Gsm.Card.
|
|
Added a PinRetryCounts property on org.freedesktop.ModemManager.Modem.
This is dictionary that records the number of PIN tries remaining
for each of the possible PIN code types for which the modem is
capable of reporting the count. Also, these counts are kept up
to date across ChangePin and EnablePin operations, not just when
an unlock is attempted.
|
|
Otherwise, we can schedule a main loop call to
mm_serial_port_queue_process() for an object that's about to
disappear, leading to a crash.

Rearrange the primary and secondary-port disable operations so that
there's a linear chain of callbacks rather than a second dangling
callback chain for the secondary port; it's possible for the primary
port operations to complete, and for the callback to finish and start
tearing down the entire device, before the secondary port commands
run.

Keep a local cache of SMS message fragments when we perform a List or
Get command on the modem; use this cache to reassemble fragments into
complete messages, which are then what is returned by the Get and List
DBus commands. Similarly, cause Delete to delete all known parts of a
multipart message.
While here, remove some extra whitespace in the SMS commands we send
to the modem.

The "glib/gtypes.h" is now considered private, and only "glib.h" should be
included directly.

Some Cinterion modems send a NUL byte before the "CONNECTED" reply to "ATD"
(only during the first ATD try anyway).
This fix will ignore any NUL byte leading the real response.
|
|
In particular, g_regex_match() and g_regex_match_full() allocate a
match_info structure on both success and failure, so calling
g_match_info_free() only in the success case is insufficient.

When receiving a SMS message with raw 8-bit data, sanitize it by
replacing non-ASCII characters with \xNN escape sequences. This
prevents a problem further down the line where the body of the message
is passed into DBus as a string, and DBus requires strings to be UTF-8.

On a ZTE MF626, sometimes the aux port will respond only with
"ERROR" to probing commands (while the SIM is starting up) and
previously we'd lose the port because we were only looking for
valid probe responses. But if the port returns ERROR or CME ERROR
etc we know it's an AT port and that we can use it once we've
gotten the type response (CDMA or GSM) from the main port.
|
|
When connecting, and the modem isn't yet registered or denied, poll
both CS and PS registration state instead of just CS state, because
we're really more interested in PS state anyway. If at least one
of the CS and PS state checks is successful then proceed with the
connection.

If there was data waiting, the task freed it, but then the port
got closed, and the data callback might have freed the data again.

It seems the Motorola Flipout with Android 2.1 doesn't like to return
configured PDP contexts via AT+CGDCONT?; it returns an error. It
seems to accept the rest of the dial sequence though, so just ignore
the error when reading existing PDP contexts.

d3c2228f7b55465f4433bedb36d47744b8d791f1 (bgo #650740)
Fix one more possible memory leak (left un-fixed by d3c2228 but not
caused by it) and ensure that modems that do want flashing get it
by default by adding the missing G_PARAM_CONSTRUCT so FLASH_OK
defaults to TRUE.
|

Flashing is a technique to break out of the data/PPP stream and
re-enter command stream (like +++) and MM uses it in the generic
paths in various cases. But devices that don't need it (ie, ones
with at least one AT capable port that won't be used for data)
now sometimes appear to have side-effects.
The Ericsson F5521gw firmware R2A07 resets port attributes like
echo and &C and such when the port is flashed, leading to
confusion on the part of MM. Since the Ericsson devices will
always have at least one free AT port they don't need flashing
anyway.
|
|
No point in requiring these to be done from the primary port.
|
|
Generic code (like the QCDM CM/HDR checks) would determine the EVDO
registration state, which would then get blown away by the device-specific
registration state query method. Modems that have a more specific check
were fine, but generic devices that don't have more specific reg
state checks can simply rely on the generic checks done earlier and
don't need to update the EVDO state from real_query_registration_state().

Fourth and final in a series.
This fixes an off-by-one (septet) error in the calculation of the
amount of data to skip in the presence of a user data header, and adds
the test case from the wild that triggered it.
|
|
Third in a series. This fixes the bug detected by the dcsf1 test in
the just-added unit tests, by more thoroughly parsing the TP-DCS
field.
|
|
Second in a series. Builds on the previous by actually unit-testing
the sms_parse_pdu() function. Note that the dcf1 test does not pass
as the code is currently written.
