Patch has been applied, however you made one small error here:

The break statement seems to be in error and I fixed it in a follow on
commit. Let me know if I was wrong.

Yes, that is error, thanks for correction. And sorry for the mistake.
What is still missing from the integration point of view? Thanks in advance!

I've reviewed the other patches, however I'm not completely happy with
the API changes and a few scenarios do not seem to work. I spent most
of Friday trying to figure out better alternatives, but have not come up
with anything yet. Let it stew in my brain for a bit longer.

So for consistency sake I think we should introduce
g_at_ppp_set_ipv6_server_info(GAtPPP *ppp, const char *remote_prefix);
For the local prefix, I'm leaning towards creating a new set of v6 and
dual-stack specific constructors:
g_at_ppp_ipv6_new(const char *local_prefix);
g_at_ppp_ipv6_server_new(const char *local_prefix);
g_at_ppp_ipv4v6_new(const char *local_prefix);
g_at_ppp_ipv4v6_server_new(const char *local_ip, const char *local_prefix);
The key difference between constructors being whether to create ipcp,
ipv6cp or both. We might need a _full version of the server
constructors as well. I'm not entirely happy with this, so if you have
better ideas, I'd love to hear them.

That looks OK to me. Regarding alternatives, one would be:
enum ofono_ppp_proto {
OFONO_PPP_PROTO_IP = 0x1,
OFONO_PPP_PROTO_IPV6 = 0x2,
OFONO_PPP_PROTO_IPV4V6 = 0x4,
};
struct _GAtPPP {
[...]
guint8 proto;
};
g_at_ppp_new(guint8 proto);
or/and
g_at_ppp_set_proto(GAtPPP *ppp, guint8 proto, ...);
The usage would be:
- IPv4 only:
g_at_ppp_new(OFONO_GPRS_PROTO_IP);
- IPv6 only:
g_at_ppp_new(OFONO_GPRS_PROTO_IPV6);
- IPv4v6, both optional, but at least one is mandatory:
g_at_ppp_new(OFONO_GPRS_PROTO_IPV4V6);
- IPv4v6, both mandatory:
g_at_ppp_new(OFONO_GPRS_PROTO_IPV4V6 |
OFONO_GPRS_PROTO_IP | OFONO_GPRS_PROTO_IPV6);
- IPv4v6, IPv4 mandatory:
g_at_ppp_new(OFONO_GPRS_PROTO_IPV4V6 | OFONO_GPRS_PROTO_IP);
and so on.
For g_at_ppp_set_proto(GAtPPP *ppp, guint8 proto, ...) there might be optional
parameters (one IPv4/IPv6 local address or both IPv4 and IPv6 local addresses),
depending on the need. And similarly for g_at_ppp_set_server_info().

Oleg

There are some interesting ideas here, but I want to keep the API
changes and the impact on existing code minimal for now. This means not
touching the original API if possible.
Besides, we simply don't know if we need all this flexibility, so lets
just consider the ipv4 only, ipv6 only and both ipv4 and ipv6 being
required as use cases we want to address.

-Denis

Sure, let's keep it simple then. I will prepare another patch.

Actually you can't do it this way. There's only a single IP layer, so
it is considered 'live' as soon as one of the NCPs (e.g. IPCP or IPv6CP)
has been negotiated (e.g. went to 'up' state).

See my previous comments, entering of the LINK_UP phase can happen as
soon as one of IPCP or IPV6CP has been negotiated, so this needs to be
reworked a bit. If it makes things easier, for now we can assume that
if IPCP or IPV6CP goes down, then the other one should probably be shut
down as well, if it exists.

Thanks for the explanation of the semantics here.
Regarding the ppp_net, it might be possible to do just with one instance,
enhancing struct ppp_net with guint8 proto field. The protocol that goes up
first, creates the interface, the second one just adds relevant protocol
configuration. Maybe, the reference counter, would be useful here then.
What would be the preferred approach here?

I added it for consistency. But, true, it isn't needed, I will drop it.

OK, understood. Let me check this once again, I will try to address this.

That sounds fine, basically we need a single TUN interface to handle
both IPv6 and IPv4 packets. We can probably get by with simply checking
the state of each NCP inside ppp_drop_packet on the rx side.
On the tx side we most likely need to peek inside the IP packet to
figure out and set the protocol accordingly.
