Denis Kenzior 1149210e16 ppp: Use auth->proto, not ppp->proto 
Otherwise we move on to NCP stage prematurely
 2010-04-06 23:11:26 -05:00

Denis Kenzior 7b447dd0e2 Refactor: Move valid code selection to ipcp/lcp 
We already have a set_valid_codes function, let us use it
 2010-04-05 16:16:14 -05:00
Denis Kenzior 4f5de3426e Refactor: Move packet_ops to a static look-up 
No need to allocate space for this, as it is always the same for all
instances.
 2010-04-05 16:14:39 -05:00
Denis Kenzior 48a012c810 Refactor: Make option_scan more type safe 2010-04-05 14:32:11 -05:00
Denis Kenzior 5e8a9c2941 Refactor: Make option_process more typesafe 
option_process was declared with two gpointer arguments for the sole
reason of being used as a GFunc.  Casting to a GFunc or re-writing the
foreach as a loop is preferable.
 2010-04-05 14:25:14 -05:00
Denis Kenzior 60d96505dc Refactor: Add pppcp_set_data & pppcp_get_data 
Using these functions makes the code much cleaner than trying to pass
the priv pointer everywhere
 2010-04-05 14:16:00 -05:00
Marcel Holtmann 331fcaea32 Make pppcp_code enum a private structure 2010-04-05 11:12:43 -07:00
Marcel Holtmann 12ffb2c772 Make pppcp_event_type enum a private structure 2010-04-05 11:05:08 -07:00
Denis Kenzior 64ffcf1cfa Refactor: Move to a transition state table 
It is much more compact to re-implement the transition states as a table
as opposed to functions with switch/case statements.  The logic is made
much easier to follow and much of the code duplication is eliminated
 2010-04-05 12:36:43 -05:00
Denis Kenzior d6517e63fe Refactor: Make the enum assignments explicit 
They will be used for certain magic later on

Denis Kenzior 349d4d8c5d Remove the PPP option from gsmdial 
Pointless since we should always connect using PPP
 2010-04-02 15:13:25 -05:00
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.
 2010-04-02 15:11:48 -05:00

Kristen Carlson Accardi 74e1abd353 ppp: use queue to transmit 
Since we are using non buffered I/O, use a queue to transmit when buffer
space is available.
 2010-04-02 13:05:47 -05:00
Denis Kenzior 1ed6966cb4 Split out ipcp protocol into ppp_ipcp.c 2010-04-02 12:53:45 -05:00
Kristen Carlson Accardi c2a589e732 ppp: fix event generation on close

 2010-04-02 12:53:45 -05:00
Marcel Holtmann edba0296c5 Remove PPP CP event_queue handling and process events directly 2010-04-01 21:44:07 -07:00
Denis Kenzior a182034336 Fix: Stop infinite attempts to register 
Sometimes if the modem firmware is particularly nutty we will see
frequent cell-reselections at startup, resulting in us attempting to
register multiple times.  Try to stop this behavior by keeping track of
what state we're in and hoping the hardware is at least somewhat sane.
 2010-04-01 22:32:58 -05:00
Marcel Holtmann a845dc8da7 Remove obfuscation for some of the event handling 2010-04-01 20:40:39 -07:00

Denis Kenzior 988b24adb0 Fix: Introduce PPP data state 
Some modems send PPP data introspersed along with the CONNECT final
response.  Fixup the parser so we can still detect the final response.
 2010-03-31 18:48:52 -05:00
Denis Kenzior ee8084c0d0 Fix: Update gsm dial to the new GAtPPP API 2010-03-31 18:48:30 -05:00
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.
 2010-03-31 18:47:30 -05:00
Denis Kenzior d6093b819f Refactor: GAtPPP connect callback 
The connect callback was not giving enough information and the
information it was providing was not in a convenient form.

- Provide the ppp interface name (e.g. tun0)
- Provide ip, dns1 & dns2 as strings
- Do not send the ppp structure in the callback, it is most likely
  present in the user data anyway
 2010-03-31 18:45:17 -05:00

Also use proper indentation style

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.
 2010-03-26 19:19:46 -07:00
Kristen Carlson Accardi 3772a6401c ppp: comment fix

Kristen Carlson Accardi 5b656cdf34 gsmdial: shutdown ppp link if we have one 
If we have created a ppp link, shut it down when the signal handler
is called.
 2010-03-25 06:50:17 -07:00
Kristen Carlson Accardi f720a27a1f separate memory cleanup from PPP shutdown 
don't free memory at PPP shutdown, because we need to be able to
send terminate traffic.  Free memory when we have reached the
PPP_DEAD phase instead.
 2010-03-25 06:50:10 -07:00
Kristen Carlson Accardi 06ae2b2c98 add tracing for PPP terminate path

Prevent conflicts between config timer information and terminate timer
information by providing a new data structure which keeps timer information
for config and terminate requests separate.
 2010-03-24 23:04:45 -05:00
Kristen Carlson Accardi fb40115bf2 switch to g_timeout_add_seconds() 
we don't care that much about the exactness of our timer, so use
the more power efficient call.

Denis Kenzior 1905d4deda Fix: Make CONNECT <baud> responses work 2010-03-24 19:42:16 -05:00
Denis Kenzior 9ed01bfecd Refactor: Simplify parsing logic 
It isn't actually necessary to check the basic command prefixes, if the
extended prefix doesn't match we try to parse it like a basic command.
That one does the same exact check anyway.  If that fails, then this is
not a recognized command line anyway.

Denis Kenzior c1c3b5502e Style: No point to write a function to wrap g_free 
Using casting magic works well enough, and more consistent with the rest
of the library.

It's the basic skeleton of GAtServer, including new/shutdown, ref/
unref, received_data/parse_buffer and set_discuss/set_debug.

GAtServer is to emulate the server side of AT conversation. It
complies with V.250 and 27.007 spec to accept AT command like
ATV1, ATE0 and extended command like AT+CLCC. Upper layer could
create customize server to expose TTY, tcp or unix socket to
client side application.

Denis Kenzior e8d18946b9 Fix: One more fix for disconnect detection 
In situations where lots of data is generated by the remote side (e.g.
phonebook is being read) we can get our ring buffer filled up.  In this
case setting rbytes to zero first and then breaking out of the loop
leads to an erroneous disconnect detection.  The fix is to move setting
of rbytes after we know we still have some space.
