2011-02-28mgcp: Introduce a mgcp_trunk_config enum for endpoint configsHolger Hans Peter Freyther2-3/+3
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.
2011-02-27nat: Fix some corruption in the test caseHolger Hans Peter Freyther1-0/+2
2011-02-27nat: Change number of multiplexes to the max-endpointsHolger Hans Peter Freyther1-3/+4
2011-02-26nat: Allocate endpoints from multiple multiplexes.Holger Hans Peter Freyther1-0/+45
This code allocates endpoints from multiple multiplexes but will always leave 0x0 and 0x1f unassigned in the multiplex.
2011-02-26nat: Verify that we are not assigning 0x1f as endpoint.Holger Hans Peter Freyther1-5/+5
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.
2011-02-26nat: Allocate the endpoint status dynamicallyHolger Hans Peter Freyther1-2/+2
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.
2011-02-25nat: Update the tests to make them going againHolger Hans Peter Freyther2-4/+7
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.
2011-02-11[BSC] Move the BTS-type specific code from bcs_init.c to bts_*.cHarald Welte5-20/+2
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.
2011-01-07mgcp: We want to count trunks starting from one.Holger Hans Peter Freyther1-2/+2
2011-01-06mgcp: Parse a Digital Trunk endpoint name.Holger Hans Peter Freyther3-1/+95
2011-01-06subscr: Dump the pending requests to help with debugging state.Holger Hans Peter Freyther2-0/+2
2011-01-06subscr: Stop all paging requests if one is failing.Holger Hans Peter Freyther1-0/+1
If one paging request is timing out the others will timeout soon as well. With the current code the next timeout would expire the next request in the queue. We will now stop all paging requests and then issue a next paging request. So for both paging success and failure we will now stop all the other requests. This is mostly a workaround, one should count on how many BTSes we are paging and wait for all failures before we remove the item from the queue.
2011-01-01License change: We are now AGPLv3+ instead of GPLv2+Harald Welte5-25/+20
The reason for this is quite simple: We want to make sure anyone running a customized version of OpenBSC to operate a network will have to release all custom modifiations to the source code.
2010-12-22misc: Remove gsm_subscriber.h from the db.h fileHolger Hans Peter Freyther1-0/+1
Reduce the dependencies on the header files.
2010-12-21test: Make it compile but it is segfaulting on start nowHolger Hans Peter Freyther1-0/+2
2010-11-15misc: Introduce a --enable-coverage mode to build with gprof coverageHolger Hans Peter Freyther2-2/+4
This adds a test coverage build. One can use gcov and lcov on the resulting data afterwards to see which code paths were executed and which were not.
2010-10-28nat: Add test case for matching phone numbersopenbsc/0.9.100.9.10Holger Hans Peter Freyther1-0/+62
Add the test case for matching '*' and for not matching at all
2010-10-27nat: Implement rewriting, have a very basic test for that featureHolger Hans Peter Freyther2-0/+107
2010-10-21nat: Copy the IMSI, then free it or move the context to the connectionHolger Hans Peter Freyther1-1/+3
Extract the IMSI from the first message as well and safe it in the connection structure. The problem is that we do not have this structure at this point, so we will allocate the imsi as child of the bsc_connection and then move/steal it.
2010-10-19nat: Change the order of the DENY/ALLOW rule for the BSC.Holger Hans Peter Freyther1-1/+18
Currently it is not is not easily possible to disable everyone and then only allow certain SIMs. By changing the order we can do: access-list imsi-deny only-something ^[0-9]*$ access-list imsi-allow only-something ^123[0-9]*$ and still keep the usecase of only forbidding certain SIMs on certain LACs. Adjust test case, test that the other cases are still functional.
2010-10-12misc: Replace the idiom for replacing a string with a function callHolger Hans Peter Freyther1-1/+2
Remove a lot of code in favor of a new function that is freeing the old string and copying the new one. I should have gotten the context and the strings right.
2010-10-08nat: Allow a BSC to have multiple LACsHolger Hans Peter Freyther1-8/+18
Make it possible that one BSC is serving multiple cells. Introduce a list of lacs, add functions to manipulate the lists. The current test cases for paging by lac continue to work.
2010-09-20nat: Test for a bug inside the TLV definition for GSM 08.08Holger Hans Peter Freyther2-3/+22
The 0x1 inside a CIC IE could indicate a new IE... add test data and test case to verify that the patching works correctly.
2010-09-20nat: Test the endpoint finding a bit better...Holger Hans Peter Freyther1-3/+5
2010-09-18janitor: Move the * to the variable nameHolger Hans Peter Freyther3-3/+3
2010-09-15nat: Parse the id response, extract the IMSI, compare itHolger Hans Peter Freyther2-0/+62
Add a test case and also add a basic check that we got some size checks correct. The next step is to act on the result.
2010-09-15nat: Update the test for the new <0,0,1 semantic of the filter functionHolger Hans Peter Freyther1-5/+5
A test case with a TMSI is missing, this would be needed for better coverage of the filter test case.
2010-09-06chan: Store the to be assigned channel type in the GSM Network.Holger Hans Peter Freyther1-0/+1
Store the mapping from request to channel type in the GSM Network struct as there is some policy involved with handling the request. E.g. in a half rate network we don't want emergy calls to be getting a TCH/F, or we want to have a different policy for early/late assignment of phone calls. Update the table when creating the network and when the neci is changed.
2010-08-30nat: Replace the MGCP Endpoint if that is requiredHolger Hans Peter Freyther2-4/+4
Add code to replace the Endpoint number for the mgcp.
2010-08-29nat: Attempt to assign the BSC Timeslot based on a free listHolger Hans Peter Freyther1-4/+9
Do attempt to not reassign an endpoint immediately but go to the next free one.
2010-08-29nat: Make the code work in terms of endpoints instead of timeslot/multiplexHolger Hans Peter Freyther1-12/+5
We are going to have more than one trunk, so all code hardcoding the multiplex to zero must go. Avoid this kind of problem by saving the MGCP endpoint number and comparing that.
2010-08-03Use new include paths of libosmo-sccp 0.0.2Harald Welte1-1/+1
2010-07-31nat: Fix compilation with nat not being enabled.Holger Hans Peter Freyther1-0/+1
common_vty.c was including bsc_nat.h which tried to get the sccp/sccp_types.h which is not required to be installed. Move all structs using/embedding SCCP structures into the bsc_nat_sccp.h and include. This should fix the compilation.
2010-07-31sccp: Use the external libosmo-sccp as sccp implementationHolger Hans Peter Freyther5-862/+10
Add --enable-nat and --enable-osmo-bsc to build applications requiring the Osmo SCCP library to be installed. We are not using autodiscover as this is out of fashion.
2010-07-23nat: u_int16_t -> uint16_tHolger Hans Peter Freyther1-1/+1
2010-07-23nat: u_int8_t -> uint8_tHolger Hans Peter Freyther2-29/+29
2010-07-23sccp: u_int16_t -> uint16_tHolger Hans Peter Freyther1-1/+1
2010-07-23sccp: u_int8_t -> uint8_tHolger Hans Peter Freyther1-19/+19
2010-07-05nat: Fix the testcase and init the logging infrastructureHolger Hans Peter Freyther1-0/+1
2010-06-17bsc_api: Move gsm48_rcvmsg into the BSC API and dispatch.Holger Hans Peter Freyther1-4/+0
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...
2010-06-15nat: Add the OSMO NAT to the build process.Holger Hans Peter Freyther1-1/+1
2010-06-15nat: Make the test compile, no bssap.c, use log_targetHolger Hans Peter Freyther2-6/+5
2010-06-15nat: Allow to specify multiple entries in the access-list...Holger Hans Peter Freyther1-3/+10
Inside the access-list we have a list of entries that have either one allow or one deny rule... we do not allow to remove a single rule but one has to remove the whole list, in that case talloc will handle cleaning all entries. Right now the matching is O(n*m) as we traverse the list (multiple times) and run the regexp multiple times. One way to make it faster would be to concat all regexps into one.
2010-06-15nat: Shorten the access-list struct and method names (still way too long)Holger Hans Peter Freyther1-3/+3
2010-06-15[nat] Introduce the concept of access-listHolger Hans Peter Freyther1-3/+9
One can set one access-list to one BSC and one access-list to one NAT. The matching of IMSIs remains the same for now, also applying the white/blacklist. Access lists can not be deleted for now and no perf opt is done (e.g. one could cache the result of the last lookup in the bsc struct).
2010-06-15[nat] Make create_sccp_src_ref return the SCCP Connection.Holger Hans Peter Freyther1-3/+7
Right now it was not possible to just find a connection, by returning the connection that is created we will have direct access to it. It will be used by the local connection handling.
2010-06-15[nat] Remove parameter that is never accessed directlyHolger Hans Peter Freyther1-1/+1
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.
2010-06-15[nat] Set the connection type/reason as out parameterHolger Hans Peter Freyther1-2/+15
We are analyzing each CR message and it is nice to know the reason these connections were created. Change the nat method.
2010-06-15[nat] Parse the PAGING RESPONSE inside a CR message as well.Holger Hans Peter Freyther1-0/+16
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.
2010-06-15[nat] Remove the imsi allow option on the nat level.Holger Hans Peter Freyther1-5/+0
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
