Holger Freyther 91754473ca db.c: tmsi may be empty so put it into '' to make that obvoius (Andreas Eversberg)
during attachment, the "tmsi" field of the subscriber may be an empty
string, so the string must be quoted in the sql request, or the sql
request fails due to incorrect syntax.

also i added "extension" field to debug output.

Holger Freyther d51524f654 gsm_04_08.c: Kill duplication pointed out by Andreas Eversberg
Introduce the internal gsm0408_authorize that will determine
if we allow the user into our network. If allowed a new tmsi
will be allocated, the subscr_update will be called, the loc_operation
released, and the accept sent. Otherwise just return 0.

The code was copied from mm_rx_id_resp.

Holger Freyther 7a12faa195 gsm_04_08.c: Call subscr_update everytime we let someone in (Andreas Eversberg)
If location update is requested, but subscriber is not yet authorised
within mm_rx_loc_upd_req() function, the subscr_update() is not called,
because subscriber information is not complete.
During mm_rx_id_resp() the subscriber informations is may be complete,
so authorize subscriber succeeds and database must be updated.

Holger Freyther 3cf00fb954 Add the isdnsync program which enable layer1 and layer2 on a card
this small tool is used to enable layer 1 and 2 on a given isdn card.
the card can be used to retrieve clock signal from a network. layer 2
(PTP) is required to keep layer 1 without interruption. this tool works
on e1 and s0 cards. to use the clock signal with other cards,
interconnection with a clock-slave-card is required.

Holger Freyther 6d9f77acd0 openbscdefines.h: Add header file to control visibility of symbols
Add the hooks/configure detection to compile everything with
-fvisibility=hidden and then make certain symbols visible. This
will be used to make parts of the API public.
There are no users yet but we should have some soon.

Holger Freyther c7aa3c4f79 pkg-config: Create and install a pkg-config file
Let automake create the openbsc.pc and then install it
into the pkg-config directory of ${libdir}. This is done
in preparation for the public API that will be added soon.

The advertised include directory will be ${incluedir}/openbsc-1.0
to follow userspace practive from glib/gtk/cairo/freetype2 and
many more.

Holger Freyther eaf0469a8b gsm_04_08.c: Some spoofing protection against two location updating requests
Do not allow two location updating requests on the same lchan. Such
an event is certainly spoofed and can confuse the internal logic of
the application. Prevent that.

Holger Freyther 7c19f74084 lchan: Handle the abnormal case of channel getting closed
The abnormal case is that lchan_free ist getting called due
a RSL_MT_CHAN_REL_ACK in the RSL but the refcount of this
channel is not zero. This means that some "logical operation"
is still going on that needs to be cancelled.
Instead of always queuing up all operations in the
struct gsm_lchan use the signal framework to inform higher
layers about this abnormal case.

In gsm_04_08.c a signal handler is installed and in the
abnormal case the location updating request operation is

Holger Freyther c7b86f9011 Revert "[db] Keep track of the current gsm_network"
This was a stupid decision. We will have to assign the
network at some other place. The problem will be a problem
when we have two gsm_networks in one process and the same
subscriber is traveling in both networks.

Holger Freyther c3d4b2d441 [subscr] Remove the struct gsm_bts pointer from subscriber
The pointer was initially added to support to open a lchan
by using the gsm_subscriber structure. We would have restored
the struct gsm_bts from the db when loading the subscriber.

Instead we will dynamically resolve the gsm_bts and might end
up paging multiple bts in the same (stored/old) location area
until it answers.

Holger Freyther 2e99605b7e [misc] Search for the crypt symbol to conditionally enable crypt in VTY

needed, $(LIB_CRYPT) will be -lcrypt.

Compiles on OS X and Linux and reenables crypt.

Holger Freyther 8521e5f050 [l2] Do not always release the layer2 when closing the socket (Andreas Eversberg)
Tells mISDN not to release layer 2 on closing socket, when not
requested. If mISDN was told to release layer 2 once, it will continue
to release layer 2 on every shutdown of OpenBSC.

Holger Freyther b8be6543cd [e1] Correctly initialize the e1link (Andreas Eversberg)
During bootstrap of BS11, the e1links are initialized. This must also be
done when BS11 is already bootstrapped (when restarting OpenBSC). It is
required to correctly multiplex the audio traffic between channels.
Without it, all time slots refer to card 0, slot 0, subslot 0, which
causes crashes when handling TRAU frames..

Holger Freyther c21cfbc4aa [subcriber] Fix the subscriber use counting in gsm_04_08.c (Andreas Eversberg)
This patch will fix subscriber usage countinig.
It may happen, that the subscriber count will not be 0 after releasing
of a call. (This problem is solved with the application patch (27),
which will replace static call transaction by a dynamic transaction
list, and use subscriber for each transaction created.)

Harald Welte 45b407ad25 With this patch, the TRAU muxing code supports not just bridging only.
A new function trau_recv_lchan() is used to link a channel to a call reference
of a transaction. (Transactions are used in later patches.) TRAU frames will
then be forwarded to the application with the given call reference (in later
patches). Also the application can send TRAU frames by using trau_send_lchan().

A new list is introduced in trau_mux.c. (upqueue_entry) All subslots
that must be sent to application are listed here.

Received TRAU frames are written in the upqueue of application
interface, if a call reference is found in the upqueue-list. If an entry
is found the ss_entry list, the TRAU frames are bridged as before. The
frames have a message type (msg_type), a call reference (callref) and a
trau frame (data). The length of trau frame is defined by the content of
the c-bits inside the frame.

There is no support for ip.access yet, as they don't use the traditional
TRAU frame format. Harald must add this in order to use application interface
with ip-access. The bridging with ip-access works as before.

Harald Welte c125a680ef A new debug flag is introduced: "DMNCC". MNCC is the Mobile Network Call

Harald Welte a4d49e96ab Some messages have one or two length-value information elements. The is
no IE type included in the message. These information elements are
mandatory, so their actual IE type is known. The improved parse_tlv()
function allows to parse zero, one, or two length-value elements.

Harald Welte e7b452a7a0 add FIXME comment about the fact that we're paging in the wrong BTS 2009-05-23 06:34:37 +00:00
Harald Welte f55b49fef3 To slow down transmission of many ABIS frames at a time, a delay timer
is used for the E1's time slot. This timer replaces the "usleep()"
function, so the process will not block the execution of libbsc. The
timer is started after a frame is transmitted. If another frame is in
the transmit queue, the frame will only be queued until the timer times
out. If the timer is not running or times out, the frame is transmitted
and the timer is restarted.

The problem with partly provisioned TRX (locks show on LMT) is solved.
The adjustment for the inter frame delay of 50 miliseconds is for
further study.
