Denis Kenzior 820b1f55c8 ppp: Refactor server-side API 
The biggest update here is that the server needs to be in dormant mode
by default, so as not to send a Configure-Req to the peer until the peer
is ready.  This requires adding special constructor for LCP to
initialize it to Stopped state instead of initial state.

Along with this, we pass the server local IP directly to the ppp server
constructor.

Denis Kenzior d7c0640412 ppp: Tweak set_server_info API some more 2010-06-29 11:49:40 -05:00
Zhenhua Zhang 588db02354 gatppp: Add PPP server extension 
1. Add interface to set PPP server info by g_at_ppp_set_server_info.
2. Pass local and peer address through IPCP handshaking.

Before sending to hdlc, set the address and control field.
Fix hardcode of ppp header size.

Denis Kenzior 9ae0dcb47d ppp: get rid of ppp_enter_phase 
This function simply didn't have the context of why the phase was being
entered.  Instead have each protocol notify GAtPPP as to what is
happening.  We already had this more or less for IPCP and AUTH events,
this just now formalizes it for LCP as well.

Kristen Carlson Accardi 71775550fe ppp: implement MRU option 
If the peer requests a MRU option, set the mtu for the network
phase.  When we are in link establishment phase, we should
continue to behave as if no option has been set and the peer
should use the default MRU.

This option is required for the Huawei E160G modem.

Kristen Carlson Accardi 60643ee287 ppp: nak unknown auth protocol 
If we are sent a Config-Request for an auth proto other than
CHAP with MD5, send a NAK.

Denis Kenzior d1d73a75fc ppp: Introduce ppp_net_up_notify and use it 
This is slightly cleaner way than defining a weird callback function.

Denis Kenzior 18e5e26acb ppp: Remove auth_ functions from ppp_auth.c 
These really serve no purpose right now as we use only CHAP.  So they
only take up space and make the code harder to read.  If we implement
1-3 auth protocols, then they're easier handled inside gatppp.c.  If we
have more, then a proper auth driver framework is required.

Denis Kenzior 42f6e8ec6e ppp: introduce ppp_auth_notify 
This function will be notified whenever authentication has succeeded /
failed.  This can happen in the authentication phase or during the
network phase.  If auth fails, then we should proceed to the terminate
phase.

Denis Kenzior fed99b9265 ppp: Transition the phase directly 
Use of the generate event function, while more 'pure' with regard to how
the spec views transitions, actually makes code more difficult to read.

Instead use phase transitions directly inside gatppp.  This still bleeds
through a little into lcp code, and probably should be fixed in a better
way eventually.

Denis Kenzior 2c466c8baf Refactor: Get rid of packet handler registrations 
There are only about 4 protocols that the current ppp code handles and
it is doubtful that it will grow much more.  There's no point in having
an extensive packet handler registration framework.

Denis Kenzior cc1bb46ffa Refactor: Use GAtDisconnectFunc for ppp disconnect 
The ppp argument to the current disconnect callback is useless as the
ppp structure is most likely stored in user data anyway.

Kristen Carlson Accardi 5260379d98 ppp: send Protocol-Reject 
change ppp_decode to store the length of the decoded frame, so that
if we have a packet with a protocol we don't understand, we can send
Protocol-Reject packets.  Modify ppp_cp code to add support for sending
Protocol-Reject packet.
