Fix common misspellings by using the list available at

From the list cited above, the substitution script found the following

Unset IO disconnect function when we try to destroy GAtPPP instance.
After freeing the instance, the IO disconnect function should not be
invoked.

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.

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.

Transition to DEAD when lcp is finished and ignore any io
disconnects if we are already dead.
|
|
Right now it is very hard to figure out whether we should be calling the
connect callback or the disconnect callback. So refactor as follows:
- Connect callback is only called once the net is actually up
- Disconnect callback is called once ppp is down, with a reason
for why it is so.
|
|
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.

remove call to signal_close for lcp object, it is redundent. If
our io is destroyed we are dead, so transition the ppp phase to
DEAD so our disconnect callback can be called.
|

Marcel: recording right now only works for PPP, so we'd need some sort
of multi-protocol support.
So for now expose set_recording to be used through the main PPP object.
HDLC object recording support needs to be extended.

According to the spec, you must transmit all Link Configuration,
Termination, and Code-Reject packets as if no options had been
negotiated. This requires that when encoding we use the
default ACCM of 0xffffffff when sending these types of packets.

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.

|
The read_watch and write_watches both take a ref
|
|
We will not support pfc or acfc
|
|
There really isn't a need for these now

This is slightly cleaner way than defining a weird callback function.

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.
|
|
Also refactor the set credentials function, we will be removing the auth
object shortly
|
|
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.
|
|
This removes the need for the layer_started functions in lcp and ipcp.
For LCP the link is always up unless the socket has been closed, and for
IPCP the link should be opened as soon as LCP is ready anyway.
|
|
This can happen when e.g. the modem is physically removed from the
system and it is not feasible to wait for the nice shutdown state to be
reached.

|
|
No real need to wrap them behind lcp_ functions
