Patch proposed to solve problem seen by Eswaran Vinothkumar in thread: Ofono 1.21 crashes with Sierra MC7455. Tested by Jonas Bonn on his setup.
On my side, I did that to solve an Ofono crash seen with this setup: - huawei E3372 USB key plugged - MC7304 I stop Ofono, power off and on both modems and restart Ofono immediately. Sometimes I see an Ofono crash. Here is the result of the debug I made: When sierra modem reappears, Ofono will ask Modem which service it supports. Usually modem answers quickly. >From traces, here is what happened: - Sep 26 14:11:56: modem asks the list of supported services - Sep 26 14:12:01: no answer after 5s, modem asks the list of supported services again - Sep 26 14:12:03: modem replies to request sent at Sep 26 14:11:56. Ofono crashes during message treatment Problem is that when a timeout occurs for this type of request, part of the data is released. When answer arrives, this data is used. I still have the corresponding trace but I don't think it will be very useful.
