Seems the CCFC implementation on Telit firmware is not v.250 compliant:
ofonod[445]: Aux: > AT+CCFC=0,2\r
ofonod[445]: Aux: < \r\n\r\n+CCFC:0,7\r\n\r\nOK\r\n
In certain cases the #QSS notification is never sent, or sent too early.
Make sure that we enable #QSS notification only after the modem has been
set as powered. Also make sure that we explicitly query #QSS in case we
missed the earlier #QSS notification.
EF_PNN was not being read properly (see TS 24.008, section 10.5.3.5a,
for network names format), which affected the displayed PLMN name for
some MVNOs. Some modems already read the file and return the right
string: these do not show the problem.
This patch adds a new gdbus helper to notify the clients that
GetManagedObjects reply was received and the last proxy has been
informed previously by the proxy_added callback.
The current bitshift logic in idmap incorrectly uses
the literal 1 for the value to shift in idmap_alloc(),
idmap_take(), and idmap_alloc_next(). This causes the
resulting value to be an int instead of a long, which
results in the wrong bit being set once the number of
bits to shift operand exceeds sizeof(int). Also
on some platforms, the behavior of the left bitshift
operator is undefined when this overflow occurs.
Commit abfc2b0dd5c3e33abfdf1a815b16d492c1751c06 attempted to fix a crash
related to improper reference counting, but the main issue was that the
reference was taken only during the function call (which is usually
unnecessary for single thread), but still passed a pointer to
DBusConnection to a function that is called by the mainloop. This left a
window where the DBusConnection can be destroyed.
Fixes this crash on unit/test-gdbus-client:
