The filtering architecture already allowed to specify a reject
reason but this has not been used for the access-lists. Extend
the access-list to include a reject reason and extend the test
case to honor it.

So far the payload type used in RTP streams has been taken from the
trunk configuration in NAT mode.
This patch changes the implementation to use the payload type
announced in the SDP part of MGCP messages and responses. SDP
descriptions more than one m=audio line are not yet supported
properly (always the last one is taken).
Ticket: OW#466

These tests mainly check whether the SDP parsing works properly by
looking at the payload type detected.

The jenkins runs make distcheck in the default configuration and
not with the nat enabled.
DISTCHECK_CONFIGURE_FLAGS="--enable-nat" make distcheck

* The post-routing is applied after the first re-writing. To do this
the new number is copied back into the called data structure.
* Add a testcase that goes from 0172 to 0049 and then back to 0049
using the post rule with a table lookup.
|

The test cases did not free some of the resources it allocated.
Improve the situation a bit. There is still data allocated that
is not freed at exit.
|
|
* Increase the rewritten rule to five digits (this is the easiest
for the unit test). This will add another 40kb to the runtime size.
* Create a unit test that tests adding and removing the prefix rules.
* Use the regexp match to replace from one package

Since automake 1.13 INCLUDES is depricates and causes a warning

Find the Cell Identifier from the Complete Layer3 Information and
store it for future reference. We could begin to verify that the
LAC/CI used really belongs to the BSC.

The name sccp_connection is used in the osmo-sccp code, sccp_connections
was used in the NAT for tracking a sccp_connection. Rename it so it is
obvious that the struct belongs to the nat.
The rename was done with sed:
$ sed -i s,"struct sccp_connections","struct nat_sccp_connection",g \
include/openbsc/*.h src/osmo-bsc_nat/* tests/*/*

Prepend the international number with a '+' and then do the normal
re-writing on it. There are a couple of ways to handle this:
\+([0-9]), \+[0-9][0-9]([0-9]), \+49([0-9])
Add a test case for the international re-write based on an already
internationalized number.

We want to send a TRAP with the MGCP statistics from the NAT and
the connected BSC. The BSC endpoint can be either released because
of a DLCX from the MGCP CallAgent or the SCCP Connection release on
the A-link.
This is why we need to queue the statistics when the deleting the
endpoint on the BSC. The processing is continued once the response
arrives. This code assumes that the response of the DLCX will be sent
by the remote side. The current amount of outstanding responses can be
seen on the VTY. This assumption is based on the fact that the BSC has
already responded to the CRCX and maybe to the MDCX.
The MGCP RFC is bended to prefix the transaction identifier with "nat-"
to easily detect the response and hand it to the handler. This will
then parse the response and generate the TRAP. The current version is
v1. We assume that the transaction space is big enough and we will
not re-assign the transaction identifier too early.

Instead of handling MGCP through the UDP socket, read and write messages
through the ipa connection to the MSC.

|
|
In preparation for another kind of black-list allow the filter code
to decide how the connection should be rejected. Introduce a new struct
that will carry the reject causes for certain operations.
|
|
Move all routines related to filtering to a separate file.
|
|
Move the code around to make it more clear what the routines should do.
|
|
This assumes that AMR is used and/or the mode-set is ignored for other
codecs by the remote end.

|
Internationalize the number like we do it for Call Control. Update
the test result to match this new behavior.
|
|
Introduce number rewriting of SMS-SUBMIT. Introduce a new list,
move code around to help with finding a new number, somehow the
number encoding for TP-DA is borked, 03.40 references 04.11 but
the length appears to be strlen(number) without taken the type
field into account.

Match IMSI and destination address against a set of entries, if it
is matching the header will be modified and no sender report will be
requested. Change the test case to request the sender report and then
verify that this bit is reset to 0.

SMS went from SAPI=3 to SAPI=0 and nobody notices on the NAT->MSC direction.
|
|
The quality of the tests is of different value but it is good to
get started and improve from here.

|
Move the regexp parsing code from the NAT to libcommon as it will
be used by the NAT and BSC code. This also adds the #include <regex.h>
include to gsm_data. This header should be split up.

This is a big patch that ports openBSC over libosmo-abis.
Sorry, the changes that are included here are all dependent
of libosmo-abis, splitting them into smaller pieces would
leave the repository in some intermediate state, which is
not desired.
The main changes are:
- The directory libabis/ has been removed as it now lives in
libosmo-abis.
- new configuration file format for nanoBTS and HSL femto, we
need to define the virtual e1_line and attach it to the OML
link.
- all the existing BTS drivers (nanoBTS, hsl femto, Nokia site,
BS11 and rbs2000) now use the new libosmo-abis framework.
- use r232 input driver available in libosmo-abis for bs11_config.
- use ipa_msg_recv instead of old ipaccess_read_msg function.
- delete definition of gsm_e1_subslot and input_signal_data.
These structures now lives in libosmo-abis.
Most of this patch are deletions of libabis/ which has been
moved to libosmo-abis.
This patch also modifies openBSC to use all the new definitions
available in libosmocore and libosmo-abis. In order to do that,
we have replaced the following:
- DINP, DMI, DMIB and DMUX by their respective DL* correspondences.
- SS_GLOBAL by SS_L_GLOBAL
- SS_INPUT by SS_L_INPUT
- S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN
- SS_INPUT by SS_L_INPUT
- S_INP_* by S_L_INP_* sub-signals
- E1INP_NODE by L_E1INP_NODE vty node
This patch has been tested with:
- one nanoBTS
- the HSL femto with the examples available under libosmo-abis
- BS11 with both dahdi and misdn drivers.

Match the used SMSC and the destination of the SMS and change
the SMSC address if both are matched.
|
|
Use the same filtering infrasturcture to patch the SMSC
address in a CP-DATA/RP-DATA message. Add a very simple
testcase for this code.
|
|
Refactor the code to allow having different handlers. The goal
is to be able to patch some SMS messages too.
|
|
The idea that MCC and MNC is enough to classify a subscriber
turns out to be wrong. Certain operatos license a number range
of IMSIs to others. When we see a '^' in the MCC field we treat
it as a regexp. The code now turns the MCC/MNC into a regexp
for the IMSI. It is not using extended POSIX regexp to match
the behavior of the access list.
|
|
Use the libosmocore code to ignore certain signals by
default (e.g. SIGHUP, SIGPIPE) and use the new code to
create a default stderr logging target and initialize
it properly.

The current code tries to find _one_ bsc for a paging message
and then continues. The new code will try to find multiple BSCs
for each LAC. This is done in preparation of having two BSCs
handle the same LAC. This code right now is O(m*n) but it will
be worse once paging groups are landed.
The code to test the function was reduced to just test the lac
lookup code as the other part can not be tested in a standalone
setup anymore.

If the regexp fails to compile the internal dfa is NULL and a
regexec will crash nicely. Fail and free the string if the regexp
fails to compile.

In 136f453dd2492b95004461a33c90b11732f33bd8, I forgot to update
the new header path in the test/bsc-nat files (this happened to
me because I forgot to configured openBSC without --enable-nat).

We want to support real trunks in the MGCP code and we need to
have some better book keeping for those. Move the code around.
|
|
|
|
|
|
This code allocates endpoints from multiple multiplexes but
will always leave 0x0 and 0x1f unassigned in the multiplex.
|
|
On a classic BSC we have 32 channels but one is reserved for
signalling. Make sure that we are not assigning 0x1f as we
assume that this is the signalling channel. This means that
from 32 possible voice channels we are only going to use 30
as we are already not using the 0x0.
|
|
Allocate the status for an endpoint dynamically. We will support
BSCs with different amount of multiplexes and need to have this
flexibility in the future. Add the proper null checks to the
current users of this code.
|
|
We now need to have access to a mgcp_cfg and the change to the
setup number patching needs new data. We now set the number to
international type.
|
|
bsc_init.c was a big mess even only for two supported BTS models,
so before adding more BTS types, this needs a cleanup.
All the BTS specific code from bsc_init.c has now moved into
bts_{siemens_bs11,ipaccess_nanobts}.c
This has required that input_event() and nm_state_event() get both
converted to proper libosmocore signals instead of referencing external
symbols.
