Hi,
So far we have been discussing CID races, but if we solve the CID issue,
we still might end up with two "identical" Connections activated with the same
connection properties (APN, Username, Password), one initiated by the modem
in the LTE Combined Attach procedure and the other being a "normal

Hi,
My two cents on context activation race: the collision between a network
initiated context activation and UE initiated context activation. There is a
potential issue if the modem and ofono try to assign the same CID at the same
time
Basically the sequence of AT commands looks like the foll

Negative, to my understanding the CID is allocated in src/gprs.c and used
when activating

How do we assure that this CID is not already in use?
I think the M7400 is going to use CID=0 and M700 uses CID=1.

ofono_gprs_context_activated : this function is symetric to
ofono_gprs_context_deactivated.
This function must be call by any gprs-context driver when a context has been
activated without explicit request.
