Nico Golde 4df2ad9ac6 [SMS] avoid mktime on NULL 
gmtime(NULL) returns NULL at least in glibc and *can not* be used as
time(NULL). Since we compare two time_t values when checking the validity
period this can be replaced by time(NULL)

Holger Hans Peter Freyther c8bf3c178f misc: make the compiler happy... 
The compiler treats uint8_t*[] and uint8_t* differently,
use the address of the first element and assign that.

Thanks to Sylvain for the hint that lead to this fix.

Holger Hans Peter Freyther db4ef0d369 bsc_api: Remove the lchan usage from the Paging Response handling. 2010-06-21 16:40:09 +08:00
Holger Hans Peter Freyther 758f4dfa17 silent_call: Use the gsm_subscriber_connection instead of lchan->conn 2010-06-21 16:40:09 +08:00
Holger Hans Peter Freyther 1afbd76155 abis_nm.c: Reading the in_addr can lead to unaligned memory access 
The value of the in_addr might not be 32 bit aligned and reading
it can generate an alignment error on ARM. Fix it by using memcpy
to copy the data into a local variable.

There are many more potential alignment issues that we will fix
when we hit them.

Holger Hans Peter Freyther 34949ae924 bsc_init: Avoid unaligned access to nanobts_attr_nsvc0 
nanobts_attr_nsvc0 + 10 is unlikely to be 32 bit aligned
and will trigger an alignment error on ARM..

laforge 694a5cfe06 [BSC] RSL: Fix Channel Identification IE in RSL CHAN ACT 
We now not only include the 04.08 channel description but also
the 04.08 Mobile Allocation nested IEs

Harald Welte 9575fd0732 [BSC] add example hopping config file for BS-11 in 2TRX config 2010-06-20 16:08:36 +02:00

laforge f87ebe69d5 [BSC] NM: Correct treatment of ARFCN_LIST for BS-11 
For Siemens BS-11, the 'length' value of the ARFCN_LIST IE is interpreted in
violation of the spec.  The spec says it is a length in octets, while Siemens
treats it as 'count of 16bit ARFCN values'.

laforge 09108bff95 [BSC] RSL: properly include MA in IMM ASS CMD 
When we build an IMMediate ASSign CoManD for a hopping channel,
we need to include the length of the MA in the total length of
the 04.08 message

Harald Welte c8794b5977 [BSC] SI: make sure we initialize the data field, not the bitvec structure 2010-06-20 10:44:54 +02:00
Harald Welte 9da921b8b0 add more executables to .gitignore 2010-06-20 10:44:54 +02:00
Harald Welte 29aca17ed0 [BSC] Hopping: Add MA IE to ASS CMD, IMM ASS CMD and HO CMD 
Also, make sure the bit ordering in the pre-computed MA is correct,
as well as the cell channel description of the target cell being
present in the HO CMD.

Harald Welte 7401ae6a79 [BSC] Keep a SYSTEM INFORMATION cache for each BTS 
This will later be useful for handover where we need to copy the cell
channel allocation into a normal 04.08 message

Harald Welte fd3708976a [BSC] Generate MA for each timeslot that has hopping enabled 
The MA is used in 04.08 channel assignment related messages
 2010-06-20 10:44:53 +02:00
Harald Welte c2fb3d0c3d [BSC] Make sure we only enable hopping on BTS that support it 2010-06-20 10:44:53 +02:00
Harald Welte f3d8e92731 [BSC] introduce the concept of 'BTS features' 
We can then check if a bts supports a certain feature or not.
 2010-06-20 10:44:53 +02:00
Harald Welte a39b0f2bb7 [BSC] Implement per-timeslot ARFCN lists for frequency hopping 
We now compute the Cell Channel Description for SI 1 by bit-wise
OR of the ARFCN bitmask of each timeslot on all the TRX of the BTS.

Also, support generating a GSM 04.08 Channel Description IE for
the hopping case (with HSN/MAIO instead of ARFCN).

What's still missing now: Sending the 04.08 Mobile Allocation IE

Harald Welte 6e0cd04725 unfinished support for hopping channels 2010-06-20 10:44:52 +02:00
Harald Welte b37e5f8a60 [BSC] mISDN: Avoid sending RSL messages to wrong channel number 
In some cases, we get a DL_INFORMATION_IND with a wrong channel
number, and only in the DL_ESTABLISH_IND we will see the real
channel number that is to be used for this (TEI, SAPI) tuple.

Harald Welte b88b6d3ea6 [wireshark] Major wireshark OML dissector 
Now it properly parses message types and IEs that are defined different
depending on the BTS vendor / A-bis implementor.  This fixes a lot of
decoding bugs with Siemens BS-11 traces.

Holger Hans Peter Freyther 8330c1c386 nat: Count the number of dropped SCCP and MGCP calls as well. 
Count the number of dropped calls and lost SCCP connections
due the loss of a connection to the BSC...

Holger Hans Peter Freyther f6d0e06940 bsc_api: Set the l3h header from within the dtap method 
This is fixing USSD which broke when the code was
switched to use the BSC API.

Holger Hans Peter Freyther 9764331062 bsc_api: Move gsm48_rcvmsg into the BSC API and dispatch. 
The next step in the way to the BSC API. We have a clear a
new connection was opened signal now... and the MSC could
use it...
 2010-06-17 16:41:25 +08:00
Holger Hans Peter Freyther 86481c29d4 bsc_api: Make paging/silent call work with the subscriber_connection 
Do not use the lchan for the paging but operate on the
subscriber_connection, change the signals too to not carry
the lchan but the subscriber connection... the silent call
and vty code still assume there is a lchan inside the
subscriber connection.

Holger Hans Peter Freyther 77008464be bsc_api: Move BSC API between MSC and RSL code... 
The lowlevel BSC paging API is a simple wrapper around
the RSL command. The BTS will automatically repeat these
messages but if we end up with two MSC inputs we will
need to count these messages somewhere...

Holger Hans Peter Freyther b2be195b50 bsc_api: Rename lchan_for_subscr to connection_for_subscr and update code 
With handover and late/early assignment there might be two channels
for one subscriber and only the BSC knows which one to use, so use
the gsm_subscriber_connection everywhere...
