797b9f0af0 [nat] Remove parameter that is never accessed directly 
The msgb needs to be around when we access the parsed structure
but that needs to be guranteed by the caller handing out the parsed
structure.

677f0e7f90 [nat] Add the notion of a "local" connection. 
A local connection is only between the MUX and the real BSC. We will
not forward anything to the MSC. This will be needed for the IMSI
filtering as sending a CREF is not liked by every BSC...

ddbb5a4e1e [nat] Do not access the con after the removal 
In case of a RLC message we will destroy the SCCP connection. This means
that accessing the con and con->bsc will access old memory. Keep the status
local and move the con into an inner scope.

abd0719f23 gsm48: Separate CM Service Reject sending and creation. 
Split out the msg generation from the sending, this will
be used by the nat to send a refusal message.

5bac62216e [nat] Move the SCCP CREF handling into a new method. 
We will need to generate messages with a proper reason
and it is easier to do that from a dedicated method.

c93c523872 [bsc_msc_ip] Move the command to the right place 
Apparently I could not find the vty_interface_bsc.c when I was
searching for it. Move an extra BSC command into that file.

11c17233fe [nat] Set the connection type/reason as out parameter 
We are analyzing each CR message and it is nice to know the
reason these connections were created. Change the nat method.

e27740a0e2 [nat] Use the new gsm48 method to parse the MI followed by a classmark. 2010-05-16 01:13:28 +08:00
Holger Hans Peter Freyther
95defd542d gsm48: Add a generic MI from classmark+mi extraction. 
This is a generic MI extraction for the MI if it is followed
after a classmark. For the Phase1 Phones the classmark2 is not
four bytes but it might be different. This code can be used
by the CM Service Request handling as well.

775b3dc566 [nat] Parse the PAGING RESPONSE inside a CR message as well. 
Now we are parsing a CM Service Request, Location Updating Request
and the Paging Response. For all other messages we claim to not
support it and force a refuse.

Holger Hans Peter Freyther
45bb8bfc1a gsm48: Add size checks to the paging response mi parsing. 
We go from no size checks to some content checking. We should
refactor the whole classmark2 + mi parsing that is used throughout
the code into one place with proper size checking. This is the
start and requires a new libosmocore as well.

Holger Hans Peter Freyther
66ac860f62 [nat] Add code to filter the CM Service Request by IMSI. 
The code should be shared among the GSM0408 implementation
and this one, and like the LU we are not handling a TMSI
properly as we have no idea where it is coming from.

60fa0efcc8 [sccp] Make it optional to send data on a SCCP Connection Refuse 
This can be used to send a Location Updating Reject down to the
BSC when it is clear that a subscriber is not allowed.

3dfcd4636a [nat] Remove the imsi allow option on the nat level. 
For now we have:
1.) bsc imsi deny to deny at the BSC level
2.) bsc imsi allow to allow a SIM at the BSC level
3.) nat imsi deny to deny at the global level

50818d0c20 [nat] Separate exit2/exit3 as this can not be shared... 
We have tried to send a refuse for arbitary things and ended
up with a segfault... separate the exi2 and exit3 label to have
separate exits and cleanups.

id get code and sending the token.

34c0b245fb nat: Add code to parse the SCCP optional data. 
First we have the Complete Layer3 Information, then we have
the IE for the Layer3 information, then the GSM48 hdr, then
the actual content with data. Right now we are parsing the
LU but we are not filtering anything yet.
