Denis Kenzior ae24477801 ppp: Refactor server RCR action 
We need to generate the Conf-Rej / Conf-Nak in the same order as the
client sent us.

Zhenhua Zhang 28b2c32dc7 ppp: Fix incorrect packet length for little-endian 
packet->length is in TCP/IP network byte order. It needs to call ntohs()
to convert to host byte order, which is little-endian.

Kristen Carlson Accardi 2d8a1462db ppp: transition to dead when lcp finished 
Transition to DEAD when lcp is finished and ignore any io
disconnects if we are already dead.

Denis Kenzior 6d20194e75 ppp: Refactor connect / disconnect callbacks 
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.
 2010-04-30 15:31:26 -05:00
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 9d5eb5110f ppp: transition to dead when read io destroyed 
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.

Denis Kenzior c9edf56fc6 ppp: Hang set_recording off the GAtPPP object 
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.

Kristen Carlson Accardi a9c0be7339 ppp: use default ACCM when sending LCP codes 1-7 
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.

Denis Kenzior fde23f113a ppp: Request MRU if we ever get NAKed with it 
Huawei E160G hardware seems to NAK our configure request and suggest
that it will never send packets bigger than 1440 bytes.  Since we don't
particularly care (our receive ring buffer is 4K, so it can handle 2048
byte packets), we just re-send the Configure Request with the preferred
value.

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.

Denis Kenzior 15d93ad0b9 Fix: GAtMux channels should return EAGAIN

Denis Kenzior 71ddfca269 ppp: Use chap functions directly, instead of auth 2010-04-13 14:21:16 -05:00
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.
