Hi,
Changelog from v2 is:
- merge patch 3 and 4
- calls to ConnMan DBus methods are async
- setup_ppp() function is called from reply of
RequestPrivateNetwork() DBus method
- pending calls are stored into hash table and can be cancelled
- there is no more struct private_network_settings
Guillaume Zajac (3):
gatppp: Add new contructor to use external fd
emulator: add drivers to request/release private network from ConnMan
connman: add plugin in oFono to request request/release private
network

Please make sure to follow the proper coding style, see kernel coding

if you set ppp->fd to -1 after creating ppp_net, and this might become:

I'd say you're on the right track here, but modeling this even closer to
gprs-provision might be a good idea. Except you'll need to use a
callback, so something like:
struct ofono_private_network_settings {
...
};
typedef (ofono_private_network_cb_t)(...);
struct ofono_private_network_driver {

+void ofono_emulator_network_driver_unregister(

And then add __ofono_private_network_request / release to src/ofono.h
for now. Similar to how gprs_provision does things.

Should we add a new src into ofono that would implement those
request/release functions and register the ofono_private_network_driver?
Something like private-network-provision.c?
Then we would have the driver and callback type definition into
private-network-provision.h.
Kind regards,
Guillaume

Yep, I think that would be best. Call it private-network.c for now.
