Package: modem-manager-gui
Version: 0.0.18-1
Severity: normal
Dear Maintainer,
Recently, I bought a "Fibocom L810 LTE Module
(http://www.fibocom.com/product/2-1-5-4.html)" modem in the form of a mini
pci-e card, with usb id 1519:0443 and recognized as "Comneon Telit LN930". It
can be powered by the current version of modemmanager with the "Generic"
plugin.
But modem-manager-gui crashed when using this modem (it works fine with
Huawei's internal modem module and detachable usb modem). I managed to get the
core and dump a backtrace, and noticed that the order of parameters during the
call of memcpy by mmgui_module_gsm_operator_code (between stack layer #5 and
#6) is reversed!
#5 0x00007f846972b17a in memcpy (__len=17, __src=0x7f8464004223,
__dest=0x7ffd28c7ef60) at /usr/include/x86_64-linux-gnu/bits/string3.h:51
#6 mmgui_module_gsm_operator_code (opcodestr=0x7f8464004220
"00340036003000300031") at mm07.c:287
Finally, it goes to abort the execution.
I will attached the complete backtrace and info about the modem (generated with
mmcli), may it be useful to you.
