Denis Kenzior a6f910e27c gatserver: Change callback signature 
Provide the originating GAtServer to the callback

Denis Kenzior 61b30c025d gatserver: Don't bother reporting command prefixes 
The command line parser knows where the actual command line parameters
begin, so there's no need to make the callback skip the prefix and the
additional separator characters.

Martin Xu ad16e81aff PPP: Fix transmit ACCM and receive ACCM mixup 
According to RFC1662 Section 7.1, ACCM Configuration Option is
used to inform the peer which control characters MUST remain
mapped when the peer sends them.

Vinicius Costa Gomes 2702a2e349 gatchat: fix canceling in progress commands 
As g_queue_peek_head() returns the node data field, we have to compare
it against the actual command, not against the pointer to the queue node.

Denis Kenzior 99107c6c9d gatchat: remove write watcher on a disconnect 
There's a small probability that we call chat_wakeup_writer
just before the channel disonnects.  When this happens the write
watcher still fires causing a potential crash.

Marcel Holtmann 692cf6a6f6 gatchat: Add skeleton for GAtRawIP module 
This adds the basic skeleton for a GAtRawIP support. It is only the
skeleton with its intended API. It has no raw IP support yet.
 2010-10-21 19:36:18 +02:00
Marcel Holtmann 7492223f49 gatchat: Add support for slave chat instances 
This adds support to assign a slave chat instance to an existing chat
instance. The slave chat is now additionally bound by the lifetime of
its master chat instance.

In case the master is cloned, the slave chat instance will also be
cloned as well.

With this it is possible to suspend the master while still have an
active slave for notifications or extra commands.

And make unregister_group use the new function
 2010-10-14 09:42:42 -05:00
Denis Kenzior 7fd86cf94f gatchat: quit early if the group id doesn't match 
If the ID of the notify matches but the group id does not match it means
that the unregister is being called with an id that does not belong to
that particular group.  Checking further entries is no longer necessary.

This function will clone a chat object, but will create a new group
internally.

Denis Kenzior 2356ebf9ef gatchat: Make GAtChat a facade for struct at_chat 
Each GAtChat object is now simply a representation of a set of
outstanding commands and registered unsolicited notification handlers.
This makes it easy to cancel entire groups, e.g. by canceling the
GAtChat object itself rather than forcing the user into tracking all
relevant g_at_chat_register and g_at_chat_send ids.

Zhenhua Zhang a72e092d19 ppp: Add MAX_IPCP_FAILURE to avoid timeout quickly 
We use IPCP NAK response to stall the progress of acquiring the client
IP address from DHCP server. So we need to increase the max failure of
NAKs in IPCP handshaking.

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.

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.

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.
 2010-04-29 14:24:47 -05:00
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.

Shutdown was actually pointless and according to Marcel he only had it

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.

If the peer requests a MRU option, set the mtu for the network

should use the default MRU.

This option is required for the Huawei E160G modem.

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 /

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.

IPCP the link should be opened as soon as LCP is ready anyway.
