Public bug reported:
Binary package hint: network-manager
Hi.
The issue comes when a GPS device (u-blox chipset), that implement a
standard communication class (Abstract Line Control Model) to parse
positioning information in binary format, is connected to a ubuntu 8.10
machine.
The issue is coming from the fact that, in the ubuntu version of the
connection manager, there is a parse-modem functionality, that open the
newly detected device to verify if its' a modem, without the option
O_NOCTTY.
The GPS device, with a special configuration that send continuosly
binary data, is then sending the escape character to the CM, and
therefore the sistem detects a SIGINT signal and terminates.
The solution would be to add the option O_NOCTTY in the open of the
device, inside the probe_modem() function, in the probe-modem.c module.
I have tested that after this modification the CM do not crash any more.
The patch is enclosed.
Ciao,
Andrea
